    The national clinical practice guideline has recommended that prophylactic antibiotic be given in orthopaedic surgery involving joint replacements and internal fixation of fractures. The aim of this study is to assess the current antibiotics prophylaxis practice in a state level hospital. One hundred and three patients (68 males, 35 females; mean age 41.6 +/- 22.2 years) undergoing internal fixation for closed fractures and joint replacement surgery were included in this prospective study. The choice of pre and post-operative antibiotics, their dosages and duration of administration were recorded. The pre-operative antibiotics were only deemed to have been given if it was documented in the case notes and in the case of post-operative antibiotics if it was signed on the drug chart. Eighty eight percent were given pre-operative prophylactic antibiotics and 92% were given post-operative antibiotics. For patients undergoing internal fixation of fractures, the most commonly used antibiotic for both pre and post-op is intravenous cefuroxime. For joint replacement surgery, the most commonly used antibiotic is intravenous cefoperazone. The duration or number of doses of post-operative antibiotics was highly variable. It was not stated in 56% of the post-operative instructions. Post-operative antibiotic was ordered for 48 hours or longer in 10%. In conclusion, prophylactic antibiotics appear to be widely practised. The first line antibiotics as recommended by the present guideline were not given in any of the patients. Second generation followed by third generation cephalosporins are the most popular antibiotics, with a trend towards using third generation cephalosporins in arthroplasty patients. Single dose prophylaxis was rarely practised.

    Revision surgery following failed open reduction for developmental dysplasia of the hip (DDH) is technically demanding. We reviewed 12 patients in our institution that required a revision surgery between January 1994 and December 2003. The aims of this study are to identify the causes of redislocation after the primary open reduction and to determine the clinical and radiological outcome after the revision surgery. The mean age at presentation for DDH was 31 months (range 1-84) and the mean age at primary open reduction surgery was 38 months (range 15-84) and the mean age at revision surgery was 69 months (range 21-180). The mean follow-up period after revision surgery was 20 months (range 3-84). All the revision surgery was performed via an anterior Smith Peterson approach. The most common cause for redislocation was inadequate exposure and failure to release the obstructing soft tissues around the hip. The bony factors for redislocation included failure to perform a femoral shortening and excessive derotation of an anteverted femoral head combined with a Salter osteotomy. Three cases with posterior acetabular wall deficiency needed immobilization of the hip in extension as the hip tended to dislocate in flexion. Six patients had limb length discrepancy ranging from 1 cm to 4 cm and 50% developed avascular necrosis. Only 2 patients were asymptomatic and the majority had a limp and limitation of motion. All were pain free except one. In view of the technically demanding surgery and poor results after revision, the surgeon should recognize the pathology and ensure that the primary procedure achieves a stable and concentric reduction.

    Treatment of articular cartilage lesions remains a clinical challenge. The uses of prosthetic joint replace allograft and/or autograft transplant carry a risk of complications due to infection, loosening of its component, immunological rejection and morbidity at the donor site. There has been an increasing interest in the management of cartilage damages, owing to the introduction of new therapeutic options. Tissue engineering as a method for tissue restoration begins to provide a potential alternative therapy for autologous grafts transplantations. We aimed to evaluate how well a tissue engineered neocartilage implant, consist of human articular chondrocytes cultured with the presence of autologous serum and mixed in a fresh fibrin derived from patient, would perform in subcutaneous implantation in athymic mice.

    A rare case of bilateral anterior hip dislocation reduced under sedation was reported in this study. A 47-year-old man was knocked down by a car and sustained bilateral anterior hip dislocation which was reduced successfully with sedation using titrated dose of intravenous Midazolam in combination with Pethidine. A modified Lefkowitz maneuver using the manipulator's thigh as a fulcrum was used. Patient started weight bearing in the second month after injury and was walking without any hip pain at the twenty-fourth month follow-up. Thirteen case reports describing bilateral anterior hip dislocations were found while reviewing the literature and it was noticed that only one author had reported the usage of intravenous sedation (Propofol) for the reduction procedure. However, no author reported the use of Lefkowitz maneuver for this purpose. Consequently, reduction of a bilateral anterior hip dislocation is possible with sedation using a modified Lefkowitz maneuver.

    Acromio-clavicular joint (ACJ) dislocation usually occurs in young adults following trauma or sports injury. Fourteen patients underwent surgical treatment for symptomatic total ACJ dislocation (Rockwood and Matsen Type III-VI) in our unit between January 1996 and June 1997. Eight patients were operated within three weeks of injury and six in the chronic period (after three weeks). In the acute group, two patients had Botsworth procedure and six had Weaver-Dunn operations. All six in the chronic group had Rockwood procedure. Nine patients achieved excellent outcome with full range of shoulder movement, pain free and return to work within three months of surgery. Two patients had good outcome. Three other patients had satisfactory outcome with tolerable pain and light duty at three months. Two patients developed chronic shoulder pain and one had painful hypertrophic surgical scar. Two patients had screw breakage requiring revision surgery. In conclusion, surgical treatment for ACJ dislocation produces good results. We suggest that surgical treatment be the treatment of choice for young patients requiring early recovery and good shoulder function.

    This position development conference (PDC) Task Force examined the assessment of bone status in orthopedic surgery patients. Key questions included which orthopedic surgery patients should be evaluated for poor bone health prior to surgery and which subsets of patients are at high risk for poor bone health and adverse outcomes. Second, the reliability and validity of using bone densitometry techniques and measurement of specific geometries around the hip and knee before and after arthroplasty was determined. Finally, the use of computed tomography (CT) attenuation coefficients (Hounsfield units) to estimate bone quality at anatomic locations where orthopedic surgery is performed including femur, tibia, shoulder, wrist, and ankle were reviewed. The literature review identified 665 articles of which 198 met inclusion exclusion criteria and were selected based on reporting of methodology, reliability, or validity results. We recommend that the orthopedic surgeon be aware of established ISCD guidelines for determining who should have additional screening for osteoporosis. Patients with inflammatory arthritis, chronic corticosteroid use, chronic renal disease, and those with history of fracture after age 50 are at high risk of osteoporosis and adverse events from surgery and should have dual energy X-ray absorptiometry (DXA) screening before surgery. In addition to standard DXA, bone mineral density (BMD) measurement along the femur and proximal tibia is reliable and valid around implants and can provide valuable information regarding bone remodeling and identification of loosening. Attention to positioning, selection of regions of interest, and use of special techniques and software is required. Plain radiographs and CT provide simple, reliable methods to classify the shape of the proximal femur and to predict osteoporosis; these include the Dorr Classification, Cortical Index, and critical thickness. Correlation of these indices to central BMD is moderate to good. Many patients undergoing orthopedic surgery have had preoperative CT which can be utilized to assess regional quality of bone. The simplest method available on most picture archiving and communications systems is to simply measure a regions of interest and determine the mean Hounsfield units. This method has excellent reliability throughout the skeleton and has moderate correlation to DXA based on BMD. The prediction of outcome and correlation to mechanical strength of fixation of a screw or implant is unknown.

    PURPOSE: This study aims to investigate further how the coronavirus disease 2019 (COVID-19) pandemic is affecting orthopaedic surgeon in Malaysia in terms of exposure, general perceptions of risk, and the impact on their current and future practice.

    METHODS: Orthopaedic surgeons nationwide were invited through email and text messages to answer an online self-administered questionnaire collecting demographic information, COVID-19 exposure experience, perception of risk, and impact on orthopaedic practice.

    RESULTS: Of the respondents, 4.7% and 14.0% were involved in frontline treatment for COVID-19 patients with non-orthopaedic and orthopaedic problem, respectively. Respondents working in Ministry of Health had highest percentage of involvement as frontliner, 7.8% (8/103) and 20.4% (21/103) for non-orthopaedic and orthopaedic related COVID-19 treatment, respectively (not significant). Their main concern was an infection of family members (125/235, 53.2%). Majority of respondents were still working (223/235, 94.9%), running outpatient clinics (168/223, 75.3%), and continued with their semi-emergency (190/223, 85.2%) and emergency surgeries (213/223, 95.5%). Of the surgeons, 11.2% (25/223) did not screen their patients for COVID-19 prior to elective surgeries, 30.9% (69/223) did not have any training on proper handling of personal protective equipment (PPE), 84.8% (189/223) make decision to manage more conservatively due to COVID-19 and 61.9% (138/223) had their income affected. Of the surgeons, 19.3% (43/223) started using telehealth facilities.

    CONCLUSION: Direct exposure to treatment of COVID-19 patients among the respondent is low and the main concern was infecting their family member. There are still several surgeons who did not conduct preoperative COVID-19 screening and practice without proper PPE training.

    Diplopodia, being a rare congenital disorder, is infrequently discussed in published texts. Most reported cases have accounted the involvement of duplicated preaxial digits with other associated organ system and physical deformities. Here, we present an unusual case of isolated diplopodia involving postaxial toes in a child with no other organ and physical abnormalities. Radiological studies revealed a set of 10-digit-duplicated foot over the lateral aspect of the native foot, complete with phalanges and its corresponding metatarsals as well as tarsals, supplied by an anomalous posterior branch of the popliteal artery. Definitive surgery was performed just before the child was learning to walk.

    INTRODUCTION: The tendon of the palmaris longus is commonly used as a tendon graft in many reconstructive surgeries. Easy to access and at proximity to the hand, the palmaris longus tendon is considered as the optimal tendon source for hand reconstructive surgery. However, and besides its inconsistency, the size of the palmaris longus tendon is reported to show variability. The aim of this study is to look for the surgical adequacy of the palmaris longus tendon by conducting a quantitative synthesis on its length and width in human populations and its correlation with the forearm length.

    METHODS: Twenty-four studies met the inclusion criteria including 1761 cadaveric limbs.

    RESULTS: The results were as following: (a) the mean palmaris longus tendon length was of 13.9 ± 2.6 cm, (b) the mean ratio palmaris longus tendon length/forearm length was of 0.545 ± 0.06, (c) the weighted correlation value was of 0.686, and (d) the mean palmaris longus tendon width was of 4.0 ± 1.7 mm. Only five studies reported a palmaris longus tendon length of more than 15 cm. The palmaris longus tendon length was shown to vary between ancestries; the Japanese had the shortest while Malaysian the longest palmaris longus tendons. All studies but one reported a palmaris longus tendon mean width of more than 3 mm where the minimal mean palmaris longus tendon width was of 2.5 mm.

    CONCLUSION: While the requested length depends on the recipient site and/or type of reconstructive surgery, the palmaris longus tendon often met the required diameter for grafting. Our review demonstrated that while palmaris longus length varies between ancestries, its width is often adequate for grafting. In addition, the forearm length could be a good predictor of palmaris longus tendon length; such correlation could assist surgeons when planning to use palmaris longus tendon as a graft source.

    Background: Total knee replacement (TKR) is a major orthopedic surgery that is considered high risk for the development of venous thromboembolism (VTE).

    Objective: The aim of this study is to evaluate the clinical outcomes that resulted from the use of a new proposed VTE risk stratification protocol for selecting a suitable extended VTE prophylaxis for post TKR surgery patients administered in conjunction with patient education programs.

    Method: A randomized controlled trial was conducted in two medical centers in Saudi Arabia. A total of 242 patients were enrolled in the study, 121 patients in each group. The experimental group (A) was assessed by using the proposed VTE risk stratification protocol and also took part in patient education programs about TKR and its complications. The control group (B) was assessed by using the 2005 Caprini risk assessment tool and no education programs were given to this group. Both groups were followed for 35 days post operation.

    Results: The mean age of the participants was 65.86 (SD 8.67) and the majority of them were female 137 (56.6%). The mean body mass index of the study sample was 32.46 (SD 5.51). There were no significant differences between the two groups except for surgery type; the proportion of bilateral TKR in group A was higher than in group B (69/121 (28.5%) vs. 40/121(16.5%), p<0.05). There were no confirmed pulmonary embolism cases in the study sample and diagnosis of deep-vein thrombosis was confirmed in 12/242 (5.0%) of patients: 1/121 (0.8%) in group A and 11/121 (9.1%) in group B (p<0.05). The readmission rate for all patients was 2.5% (6/242), all of whom were in group B (p<0.05).

    Conclusion: The proposed VTE risk stratification protocol that was applied in conjunction with patient education programs reduced VTE complications and readmission events, post TKR surgery. Trial Registration: ClinicalTrials.gov: Identifier: NCT04031859.

    The COVID-19 pandemic has affected most healthcare systems around the world. Routine care operations such as outpatient clinics and elective surgery remain badly hit. This situation cannot continue for long as it puts patients at a higher risk for complications due to delayed management. Hence, it is essential to resume routine, especially elective surgery. Regarding orthopaedic practice, various authors and organisations have come out with guidelines to resume elective surgeries. However, clear consensus and common strategies need be derived. With this motive, we conducted a review of the literature for guidelines to resume elective orthopaedic surgery amid COVID-19 pandemic and shortlisted scholarly publications and information from regional organisations. We have summarised the information and derived an organised algorithm considering the guidelines provided by various sources. In this extraordinary time, guidelines come in as a relief for every surgeon who is in a dilemma whether to resume electives or not. Putting safety first, these guidelines or suitable versions should be followed at all levels wherever possible to avoid the lack of trained manpower in the event of staff morbidity.

    Introduction: The optimal surgical treatment for acromioclavicular joint (ACJ) injuries remains controversial. The modified Weaver-Dunn (WD) procedure is one of the frequently used techniques. Recently when it was compared with anatomical autogenous tendon graft reconstruction procedures, the results were inferior. However, these anatomical procedures are technically more demanding with small margin of error and they have tendency for postoperative pain because of extra donor site incision. Materials and Methods: Forty patients with type IV to VI ACJ dislocations were treated by modified WD procedure using non-absorbable synthetic suture passed through the base of coracoid process for augmentation of transferred coraco-acromial (CA) ligament. Functional outcome was assessed using the Oxford Shoulder Score, Nottingham Clavicular Score and Visual Analog Score (VAS) at the final follow-up after surgery. Results: The mean pre-operative Oxford Shoulder Score improved from 25.22±2.64 (range 20 to 30) to 44.75±1.99 (range 40 to 48) and mean pre-operative Nottingham Shoulder Score improved from 49.25±4.91 (range 39 to 58) to 87.27±4.39 (range 79 to 96) at last follow-up after surgery with p-value <0.001. Thirty-five (87.5%) patients had excellent outcomes, four (10%) patients had good outcomes and one (2.5%) patient had fair outcome. Thirty-eight (95%) patients had no pain while two (5%) had moderate pain based on VAS score. Conclusion: Modified Weaver-Dunn is a simple well established technique for grade IV to VI ACJ dislocation. We cannot consider this procedure as old and outdated on the argument that the long term functional outcomes are not suboptimal.

    We reviewed the incidence and treatment of flexor carpi radialis tendinitis in 77 patients (81 thumbs) who had trapeziectomy and abductor pollicis longus suspensionplasty for thumb carpometacarpal joint arthritis. Eighteen patients, 20 wrists (25%) had flexor carpi radialis tendinitis. The onset was 2-10 months (mean 4.7) after surgery. Two cases had preceding trauma. Eight cases (40%) responded to splinting and steroid injection. Ten patients, 12 wrists (60%) underwent surgery after failing non-operative treatment. Eleven wrists had frayed or partially torn flexor carpi radialis tendon and one had a complete tendon rupture with pseudotendon formation. Flexor carpi radialis tenotomy and pseudotendon excision were performed. All operated patients obtained good pain relief initially post-operatively. However, the pain recurred in two patients after 8 months. One required a local steroid injection for localized tenderness at the site of the proximal tendon stump. The other patient required a revision operation for scaphotrapezoid impingement. Both obtained complete pain relief. Our study has shown a high incidence of flexor carpi radialis tendinitis following trapeziectomy and abductor pollicis longus suspensionplasty. Patients should be warned about this potential complication.

    Glove perforation during surgery has always been a matter of concern as it increases the infection rate and the risk of transmission of blood borne diseases. To determine the common causes, the site and the awareness of glove perforations in orthopaedic surgery, a prospective study was conducted to assess the rate of glove perforation during 130 consecutive orthopaedic operations. All gloves worn by the surgical team were assessed after the surgery using the water-loading test. A total of 1452 gloves were tested, and the rate of perforation was 3.58%. Most of these perforations (61.5%) were unnoticed. The main surgeons had the most perforations (76.9%), followed by first assistants (13.5%) and second assistants (9.6%). Most perforations occurred at the non-dominant hand. The commonest site of perforation was the index finger followed by the thumb. Shearing force with instruments accounted for 45% of the noticed perforations. Majority of these occurred during nailing procedures (33%) and internal fixation without the use of wires (19%). Our rate of glove perforation is similar to other series. Most of them went unnoticed and were mainly due to shearing injuries rather than perforation by sharps. Therefore, there is an increased risk of contamination and break in asepsis during surgery.

    Sleeve fracture of the inferior pole of the patella is a rare and distinctive fracture in children with few published reports. These fractures are frequently misdiagnosed and neglected. We highlight a case of a neglected and misdiagnosed sleeve fracture of the patella in an eleven-year-old boy. This was initially diagnosed as an avulsion fracture of the tibial tubercle. A good outcome was achieved after open reduction and internal fixation.

    Staphylococcus aureus infection remains the commonest organism causing musculoskeletal infection and antibiotic is the mainstay of treatment apart from adequate and appropriate surgical intervention. The exact figure of antibiotic resistance in orthopaedic practice is not known but it is expected to be higher than previously reported as the use of antibiotics is rampant. Its sensitivity to various antibiotics differs from one center to another making local surveillance necessary. From 66 patients with musculoskeletal infections studied in our centre, Staphylococcus aureus was cultured in 50-65% of patients, depending on the sample taken. Fifteen percent of this were methicillin resistant Staphylococcus aureus (MRSA). Staphylococcus aureus was found to be sensitive to cloxacillin in 95% of patients' sample. MRSA remained highly sensitive to vancomycin, clindamycin and fucidic acid.
