    We present a case of chronic acromioclavicular joint dislocation (Rockwood type 5) in which the choice of acromioclavicular reconstruction using autogenous semitendinosus tendon graft was made due to its superiority in anatomical reconstruction of the coracoclavicular ligaments, and the impact of postoperative rehabilitation on the recovery of this patient. We also discuss the rationale behind this.

    Treatment of chronic Rockwood's type V Acromioclavicular (AC) joint dislocation remains controversial. We describe a surgical technique to reduce and maintain AC joint using a combination of gracilis autograft with GraftMax™ button (Conmed Inc, Utica, NY). Graft was prepared using running whip stitch technique with No. 5 Hi-Fi high strength suture (ConMed Linvatec, Largo, FL). Our technique reduces intraoperative clavicular and coracoid tunnel fracture and restores anatomical coracoclavicular ligament. At sixth week and third month postoperatively, the patient demonstrated good clinical and radiographic outcome.

    Objectives: To evaluate the feasibility of ultrasonographic examination in predicting 4-strand semitendinosus and gracilis tendon (4S-STG) autograft size preoperatively in anterior cruciate ligament reconstruction and to evaluate the use of anthropometric measurement to predict the 4-strand semitendinosus and gracilis tendons (4S-STG) autograft size pre-operatively in anterior cruciate ligament reconstruction.

    Method: Twenty-seven patients were included in this study conducted from 1st January to 31st December 2013. All patients were skeletally mature and scheduled to undergo primary anterior cruciate ligament reconstruction using 4S-STG autograft. Ultrasonographic examination of semitendinosus and gracilis tendons to measure the cross sectional area was conducted and anthropometric data (weight, height, leg length and thigh circumference) was measured one day prior to surgery. True autograft diameters were measured intraoperatively using closed-hole sizing block in 0.5 mm incremental size.

    Results: There is a statistically significant correlation between the measured combined cross sectional area (semitendinosus and gracilis tendons) and 4S-STG autograft diameter (p = 0.023). An adequate autograft size (at least 7 mm) can be obtained when the combined cross sectional area is at least 15 mm2. There was no correlation with the anthropometric data except for thigh circumference (p = 0.037). Autograft size of at least 7 mm can be obtained when the thigh circumference is at least 41 mm.

    Conclusions: Both combined cross sectional area (semitendinosus and gracilis tendons) and thigh circumference can be used to predict an adequate 4S-STG autograft size.

    Various methods, such as vascularized bone transfers, Illizarov bone transport, allogenic bone grafts, bone graft substitutes, are available in treating traumatic bone loss. Free non-vascularised fibular graft is an autografting method that only requires minimal facilities or expertise. However, this method is not popularized due to its avascular property and there is not many reports regarding its use in treating a large traumatic bone loss. We reported a case in our center to demonstrate its possibility of successfully treating the traumatic radial bone loss in pediatric patient. Patient had good recovery with the regain of good range of movement of forearm and there is no harvest site morbidity after two years of follow up.

    Ewing sarcoma is a primary bone malignancy that rarely occurs in the hand. Resection and reconstruction will usually result in reduced or loss of thumb function. We describe a case of successful transplantation of non- vascularized osteoarticular second metatarsal autograft following wide resection of Ewing sarcoma of first metacarpal in an 11-year-old girl. The capsule of the graft’s metatarso-phalangeal joint was repaired to achieve mobility of the joint. This enabled preservation of thumb function by a relatively simple surgical technique. Detailed surgical procedures and excellence function after 2 years following surgery are described.

    Limb salvage surgery is a treatment of choice for sarcomas of the extremities. One of the options in skeletal reconstruction after tumour resection is by using a recycled bone autograft. The present accepted methods of recycling bone autografts include autoclaving, pasteurization and irradiation. At the moment there is lack of studies that compare the effectiveness of various sterilization methods used for recycling bone autografts and their effects in terms of bone incorporation. This study was performed to determine the effects of different methods of sterilization on bone autografts in rabbit by radiological, biomechanical and histopathological evaluations.

    Introduction: Hamstring tendon (HT) and bone patellar tendon bone (BPTB) are the commonly used
    autograft in an anterior cruciate ligament reconstruction surgery. The BPTB is said to have more incidence of
    anterior knee pain compared to HT. The study aimed to compare the severity of knee pain during Islamic
    prayer kneeling. Methods: A cross sectional cohort analysis of patients undergoing ACL reconstruction surgery
    using BPTB with HT autografts was conducted to determine differences in postoperative pain while kneeling
    and ability to pray in normal position. Kneeling during prayer and the ability to sit while performing prayer
    were assessed at 3rd, 4th, 5th and 6th month. Results: There were no significant differences in mean pain score
    while kneeling at 3rd, 4th, 5th and 6th month. The mean difference of patient’s ability to perform normal
    prayers for BPTB (3.56+1.16) and HT (3.30+1.05) was found insignificant. The average number of patients in
    both groups was able to pray between 3 to 4 months post operatively as full range of motion of knee is
    allowed within this period. Total 49 patients (BPTB 23, HT 26) out of 60 were able to pray normally within 4
    months post-operation. Mostly delayed due to anterior knee pain. Conclusion: There is no different in term of
    knee pain during kneeling while performing Islamic prayer between those who had their ACL reconstructed
    either using BPTB or HT autograft.

    Introduction: Mega endoprosthesis replacement for resection of primary malignant bone tumour requires immediate and long-term stability, particularly in the young and active patient. Extracortical bone bridge interface (EBBI) is a technique whereby autograft is wrapped around the interface junction of bone and porous-coated implant to induce and enhance bone formation for biological incorporation. This procedure increases the mean torsional stiffness and the mean maximum torque, which eventually improves the implant's long-term survival.

    Material and methods: The extracortical bone bridge interface's radiological parameter was evaluated at the prosthesis bone junction two years after surgery utilising a picture archiving and communication system (PACS). The radiograph's anteroposterior and lateral view was analysed for both thickness and length in all four cortices. The analysis was done in SPSS Version 24 using One-Way ANOVA and independent T-Test. Results were presented as mean and standard deviation and considered significant when the p-value was < 0.05.

    Results: The mean average thickness was 2.2293mm (SD 1.829), and the mean average length was 31.95% (SD 24.55). We observed that the thickness and length of EBBI were superior in the young patient or patients with giant cell tumour that did not receive chemotherapy, compared to patients treated for osteosarcoma. The distal femur also had better EBBI compared to the proximal tibia. However, the final multivariable statistical analysis showed no significant difference in all variables. EBBI thickness was significantly and positively correlated with EBBI Length (p<0.001). We conclude that, for each 1mm increase in EBBI thickness, the length will increase by 0.06% on average. About 17.2% of patients out of the 29 showed no radiological evidence of EBBI.

    Conclusion: From our study, there were no factors that significantly contributed to the formation and incorporation of EBBI.

    Objective To compare long-term functional results of ACL reconstruction with a single bundle (SB) and double bundle (DB). Methods Sixty patients who underwent ACL reconstructions from January 2007 to December 2008 were retrospectively evaluated (30 SB and 30 DB ACL reconstructions). Clinical and functional outcomes were measured pre- and postoperatively in terms of anterior drawer test, Lachman's test, pivot shift test, KT1000 side-to-side difference, range of motion, International Knee Documentation Committee Scoring, Lysholm knee scoring scale (LKS), and Tegner activity level scale. The period of follow-up was 10 years. Results Clinical outcome measured showed that anterior drawer test result were equally normal for both groups (93.3%; p > 0.995); however, the Lachman test was 76.7% in the DB group and 56.7% in the SB group (p > 0.100), the pivot shift was 83% in the DB group and 50% in the SB group (p < 0.001), and KT1000 was 76.7% in the DB group and 56.7% in the SB group (p > 0.100). Regarding the functional outcome, it favored the DB group of patients, with the LKS being statistically significant (p < 0.007) and the Tegner activity level scale p-value being <0.001 Conclusions DB ACL reconstruction produces better rotational stability and gives superior functional outcome in terms of return to pre-injury activity level in comparison to SB reconstruction. DB ACL reconstruction using hamstring tendon autograft produces better functional results at 10 years follow-up.

    Objectives: We investigated the role of various biomaterials on cell viability and in healing of an experimentally induced femoral bone hole model in rats.

    Materials and Methods: Cell viability and cytotoxicity of gelatin (Gel; 50 µg/µl), chitosan (Chi; 20 µg/µl), hydroxyapatite (HA; 50 µg/µl), nanohydroxyapatite (nHA; 10 µg/µl), three-calcium phosphate (TCP; 50 µg/µl) and strontium carbonate (Sr; 10 µg/µl) were evaluated on hADSCs via MTT assay. In vivo femoral drill-bone hole model was produced in rats that were either left untreated or treated with autograft, Gel, Chi, HA, nHA, TCP and Sr, respectively. The animals were euthanized after 30 days. Their bone holes were evaluated by gross-pathology, histopathology, SEM and radiography. Also, their dry matter, bone ash and mineral density were measured.

    Results: Both the Gel and Chi showed cytotoxicity, while nHA had no role on cytotoxicity and cell-viability. All the HA, TCP and Sr significantly improved cell viability when compared to controls (P<0.05). Both the Gel and Chi had no role on osteoconduction and osteoinduction. Compared to HA, nHA showed superior role in increasing new bone formation, mineral density and ash (P<0.05). In contrast to HA and nHA, both the TCP and Sr showed superior morphological, radiographical and biochemical properties on bone healing (P<0.05). TCP and Sr showed the most effective osteoconduction and osteoinduction, respectively. In the Sr group, the most mature type of osteons formed.

    Conclusion: Various biomaterials have different in vivo efficacy during bone regeneration. TCP was found to be the best material for osteoconduction and Sr for osteoinduction.

    Despite increasing use of bone graft in Malaysia, there was still lack of data to quantify knowledge level on bone banking among orthopaedic community who are involved in transplantation related work. Therefore, a survey on awareness in tissue banking specifically bone banking, usage and choice of bone grafts was conducted. From 80 respondents, 82.5% were aware about tissue banking however only 12.5% knew of the existence of tissue banks in Malaysia. Femoral head was the bone allograft most often used as a substitute to autograft. Only 34.8% respondents preferred irradiated bone grafts whilst 46.9% preferred nonirradiated, indicating the need to educate the importance of radiation for sterilising tissues. Exhibition was the most preferred medium for awareness programme to disseminate information about bone banking in the orthopaedic community. The professional awareness is necessary to increase the knowledge on the use of bone graft, hence to increase bone transplantation for musculoskeletal surgeries in the country.

    PURPOSE OF REVIEW: To bring together and annotate publications about personalised external aortic root support reported in the 18 months preceding submission.

    RECENT FINDINGS: The total number of personalised external aortic root support (PEARS) operations is now approaching 700 in 30 centres in Australia, Belgium, Brazil, Czech Republic, Great Britain, Greece, Ireland, Malaysia, Netherlands, New Zealand, Poland and Slovakia. There are continued reports of stability of aortic dimensions and aortic valve function with the only exceptions known being where the surgeon has deviated from the instructions for use of the device. The median root diameter of Marfan patients having PEARS was 47 mm suggesting that the existing criterion of 50 mm is due for reconsideration. The peri-operative mortality currently estimated to be less than 0.3%. The first recipient remains alive and well after 18 years. The use of PEARS as an adjunct to the Ross operation to support the pulmonary autograft is being explored in several centres.

    SUMMARY: The operation requires proctoring and adherence to a strict operative protocol and with those precautions excellent results are attained. The evidence and opinions provided in the cited publications indicate that PEARS is a proven and successful prophylactic operation for aortic root aneurysm.

    The purpose of this study was to compare the use of autologous fibrin to human amniotic membrane (HAM) as a scaffold in cultivating autologous conjunctiva for transplantation in treatment of conjunctival defect. An experimental study was performed using 18 adult New Zealand white strain rabbits which were divided into 3 groups. Each group consists of 6 rabbits. The conjunctiva on the temporal site was excised to create a conjunctival epithelial defect. The excised area in the Group 1 was transplanted with autologous conjunctiva cultivated on autologous fibrin; Group 2 was transplanted with autologous conjunctiva cultivated on HAM and Group 3 was left bare. The rabbits were followed up at regular intervals until 6 weeks. The mean period of complete conjunctival epithelization was 11.50 ± 8.22 days for the autologous fibrin group, 15.33 ± 11.80 days for the HAM group and 25.33 ± 5.32 days in the bare sclera group. The epithelization rate for the autologous fibrin group was faster compared to the other two groups. However all the results were not statistically significant (p value >0.05). There were no postoperative complications noted during the follow up. Autologous fibrin is comparable to HAM as a scaffold for cultivation of conjunctiva in the treatment of conjunctival defect.

    Today, articular cartilage damage is a major health problem, affecting people of all ages. The existing conventional articular cartilage repair techniques, such as autologous chondrocyte implantation (ACI), microfracture, and mosaicplasty, have many shortcomings which negatively affect their clinical outcomes. Therefore, it is essential to develop an alternative and efficient articular repair technique that can address those shortcomings. Cartilage tissue engineering, which aims to create a tissue-engineered cartilage derived from human mesenchymal stem cells (MSCs), shows great promise for improving articular cartilage defect therapy. However, the use of tissue-engineered cartilage for the clinical therapy of articular cartilage defect still remains challenging. Despite the importance of mechanical loading to create a functional cartilage has been well demonstrated, the specific type of mechanical loading and its optimal loading regime is still under investigation. This review summarizes the most recent advances in the effects of mechanical loading on human MSCs. First, the existing conventional articular repair techniques and their shortcomings are highlighted. The important parameters for the evaluation of the tissue-engineered cartilage, including chondrogenic and hypertrophic differentiation of human MSCs are briefly discussed. The influence of mechanical loading on human MSCs is subsequently reviewed and the possible mechanotransduction signaling is highlighted. The development of non-hypertrophic chondrogenesis in response to the changing mechanical microenvironment will aid in the establishment of a tissue-engineered cartilage for efficient articular cartilage repair.

    BACKGROUND: Pterygium, a growth of the conjunctiva over the cornea, is a progressive disease leading in advanced stages to visual impairment, restriction of ocular motility, chronic inflammation and cosmetic concerns. Surgical removal is the treatment of choice, but recurrence can be a problem. Currently the best surgical option in terms of recurrence is conjunctival autograft. To date the most common surgical methods of attaching conjunctival autografts to the sclera are through suturing or fibrin glue. Each method presents its own advantages and disadvantages. Sutures require considerable skill from the surgeon and can be associated with a prolonged operation time, postoperative discomfort and suture-related complications, whereas fibrin glue may give a decreased operation time, improve postoperative comfort and avoid suture-related problems.

    OBJECTIVES: To assess the effectiveness of fibrin glue compared to sutures in conjunctival autografting for the surgical treatment of pterygium.

    SEARCH METHODS: We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 9), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to October 2016), Embase (January 1980 to October 2016), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 14 October 2016.

    SELECTION CRITERIA: We included randomised controlled trials (RCTs) in any setting where fibrin glue was compared with sutures to treat people with pterygium.

    DATA COLLECTION AND ANALYSIS: Two review authors independently screened the search results, assessed trial quality, and extracted data using standard methodological procedures expected by Cochrane. Our primary outcome was recurrence of pterygium defined as any re-growth of tissue from the area of excision across the limbus onto the cornea. The secondary outcomes were surgical time and complication rate. We graded the certainty of the evidence using GRADE.

    MAIN RESULTS: We included 14 RCTs conducted in Brazil, China, Egypt, India, Malaysia, New Zealand, Philippines, Saudi Arabia, Sweden and Turkey. The trials were published between 2004 and 2016, and were assessed as a mixture of unclear and low risk of bias with three studies at high risk of attrition bias. Only adults were enrolled in these studies.Using fibrin glue for the conjunctival autograft may result in less recurrence of pterygium compared with using sutures (risk ratio (RR) 0.47, 95% CI 0.27 to 0.82, 762 eyes, 12 RCTs; low-certainty evidence). If pterygium recurs after approximately 10 in every 100 surgeries with sutures, then using fibrin glue may result in approximately 5 fewer cases of recurrence in every 100 surgeries (95% CI 2 fewer to 7 fewer cases). Using fibrin glue may lead to more complications compared with sutures (RR 1.92; 95% CI 1.22 to 3.02, 11 RCTs, 673 eyes, low-certainty evidence). The most common complications reported were: graft dehiscence, graft retraction and granuloma. On average using fibrin glue may mean that surgery is quicker compared with suturing (mean difference (MD) -17.01 minutes 95% CI -20.56 to -13.46), 9 RCTs, 614 eyes, low-certainty evidence).

    AUTHORS' CONCLUSIONS: The meta-analyses, conducted on people with pterygium in a hospital or outpatient setting, show fibrin glue may result in less recurrence and may take less time than sutures for fixing the conjunctival graft in place during pterygium surgery. There was low-certainty evidence to suggest a higher proportion of complications in the fibrin glue group.

    We propose a standardized technique of repair and lavage with the outcomes of 50 consecutive patients treated at our institution. The perforation was closed primarily and reinforced with omental patch. It was then followed by peritoneal lavage in a focused sequential manner that involved quadrant to quadrant lavage with tilting of operating table and changing of position between the surgeon and the camera surgeon. None of our patients had postoperative intra-abdominal complications, but unfortunately 1 patient succumbed to respiratory complications. Respiratory complications was the most common postoperative complication in our series (9 patients), whereas 2 patients had ileus. There were no leaks or reoperations in our series. Laparoscopic repair and sutured omentoplasty, followed by focused sequential lavage in a systematic manner, if performed diligently, will yield good outcomes.

    BACKGROUND: Centella asiatica (L.) is a plant with neuroprotective and neuroregenerative properties; however, its effects on the neurodifferentiation of mesenchymal stem cells (MSCs) and on peripheral nerve injury are poorly explored. This study aimed to investigate the effects of C. asiatica (L.)-neurodifferentiated MSCs on the regeneration of peripheral nerve in a critical-size defect animal model.

    METHODS: Nerve conduit was developed using decellularised artery seeded with C. asiatica-neurodifferentiated MSCs (ndMSCs). A 1.5 cm sciatic nerve injury in Sprague-Dawley rat was bridged with reversed autograft (RA) (n = 3, the gold standard treatment), MSC-seeded conduit (MC) (n = 4) or ndMSC-seeded conduit (NC) (n = 4). Pinch test and nerve conduction study were performed every 2 weeks for a total of 12 weeks. At the 12th week, the conduits were examined by histology and transmission electron microscopy.

    RESULTS: NC implantation improved the rats' sensory sensitivity in a similar manner to RA. At the 12th week, nerve conduction velocity was the highest in NC compared with that of RA and MC. Axonal regeneration was enhanced in NC and RA as shown by the expression of myelin basic protein (MBP). The average number of myelinated axons was significantly higher in NC than in MC but significantly lower than in RA. The myelin sheath thickness was higher in NC than in MC but lower than in RA.

    CONCLUSION: NC showed promising effects on nerve regeneration and functional restoration similar to those of RA. These findings revealed the neuroregenerative properties of C. asiatica and its potential as an alternative strategy for the treatment of critical size nerve defect.

    Pterygium is a common external eye problem. It is more frequently seen in tropical areas regions where exposure to ultraviolet sunlight is high. Clinically, a pterygium is a wing shaped fibrovascular growth arising from the bulbar conjunctiva onto the superficial cornea. Complications of pterygium include decreased in visual acuity, dryness, foreign body sensation and persistent redness. Surgical management is the mainstay of treatment for this condition. Numerous surgical techniques have been described in the treatment of pterygium. They include the bare sclera technique, simple direct conjunctival closure, rotational conjunctival graft and conjunctival autograft. Additional treatment to some of these techniques may include the use of beta particle therapy and antimetabolite therapy. Despite the wide range of surgical procedures described for its treatment, the main concern from these procedures has been the recurrence, which could be as high as 30% to 70%. Recurrent pterygium is often accompanied by increased conjunctival inflammation and accelerated corneal involvement. Repeated surgical procedures often only worsen the situation, as loss of conjunctival tissue and scarring can result in obliteration of the fornices and mechanical restriction of extraocular movements, with clinically significant diplopia. In Hospital Tengku Ampuan Afzan, pterygium excision is the most common surgical procedure after cataract extraction. We reviewed patients who had undergone pterygium surgery in HTAA in order to determine the most effective surgical method that could minimize recurrence. PURPOSE: To compare success rates of various excision techniques performed for primary and recurrent pterygium in Hospital Tengku Ampuan Afzan, Kuantan, Pahang.
    METHODS: The outcome of 47 cases of pterygia (44 primary and 3 recurrent) excised with various techniques between January 2004 to September 2004 was retrospectively reviewed. Six clinical specialists and four trainees performed the surgical procedures. Outcome was evaluated in terms of recurrence of pterygia onto the cornea. RESULTS: The mean follow up was 3.04 months (range, 1-7 months). All pterygia were morphologically graded as intermediate or fleshy type except one. Four types of pterygium excision techniques were performed. Twenty-four cases had bare sclera, seventeen cases had conjunctival autograft transplantation, six cases had direct conjunctival closure and one had amniotic membrane transplantation done. Recurrence of pterygia occurred in thirteen eyes. Twelve cases from primary pterygia group and one case from recurrent group recurred. Recurrence rate was noted to be higher in direct conjunctival closure (4 out of 6 cases) and lowest in conjunctival autograft transplantation (2 out of 17 cases). Recurrence rate for bare sclera technique was noted to rank second in this study (6 out of 24 cases). In five cases of recurrence, subconjunctival tissue invasions were more than 1 mm but further surgical interventions were not needed at the time of this review was done. CONCLUSIONS: Conjunctival autografting was found to have less recurrent rate when compared with other techniques. The bare sclera technique was quoted to be associated with higher recurrence rate in other literatures. Interestingly in our series, recurrence rate for direct conjunctival closure technique was higher when compared to the former technique. This may be related to inadequate excision of pterygia tissue, which led to direct apposition of abnormal tissue to the cornea in the direct conjunctival closure technique. Even though the bare sclera technique is associated with a higher recurrence rate, it is still the preferred excision technique. This could be because it is less time consuming and technically easier to perform. Based on this study, conjunctival autografting should be the surgical procedure of choice for pteryigum in order to minimise the risk of recurrence.

    Osteosarcoma occurring in the humerus is often confined to the proximal part, in which case, reconstruction after excision is less daunting. When the tumour spreads down the medullary cavity distally, a total humeral replacement is often required. This is costly and beyond the means of the average patient in a developing country. An amputation is often the procedure of first resort. We report a 13-year-old boy with osteosarcoma originating from the left proximal humerus, with involvement of the marrow reaching down to the distal diaphyseal-metaphyseal junction, leaving only 6 cm of the distal humerus intact after wide resection. Reconstruction of the defect was done with a composite cement-autoclaved autograft fixed to the remaining humerus with a plate. At 40 months of follow-up, the patient is well with normal function of the elbow, wrist and hand. Salvaging the limb despite near total involvement of the humerus by high grade osteosarcoma is possible using material available in the average orthopaedic operating room.

    Giant cell tumour of tendon sheath is a benign soft tissue lesion most commonly found in the flexor aspect of hand and wrist. However, it is uncommon in foot and ankle and rare in bilateral achilles tendon. We report a case of 17-year-old female who presented with progressive enlargement of bilateral achilles tendon for six months. MRI findings showed that most of the tumour had intermediate to low signal intensity. Histopathology confirmed the diagnosis of giant cell tumour of tendon sheath. To help the patient regain the strength of the achilles tendon and walking abilities, a large area of tendon tumour was excised, followed by reconstruction with transfer of the peroneus brevis (PB) and posterior tibial (PT) tendon autograft. At two years follow-up, functional result was satisfactory.
