Cervical translaminar screw fixation has been shown to be safe, efficient and provides alternative for cervical fixation. However, its use in the Asian population should be considered cautiously because the cervical lamina diameter may not be adequate to accommodate the standard lamina screw size. We studied the average transverse lamina diameter of the cervical spine in the Malaysian population to evaluate the feasibility and safety of lamina screw fixation in this population.

Fulltext Orthopaedic infections: organisms and antibiotic sensitivity

Yusof MI, Yusof AH

Med J Malaysia, 2004 Dec;59(5):574-7.

PMID: 15889557

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.

Med J Malaysia, 2006 Jun;61(2):181-8.

PMID: 16898309

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.

Yeak RD, Daud H, Nizlan NM

Chin J Traumatol, 2019 Jun;22(3):182-185.

PMID: 31060897 DOI: 10.1016/j.cjtee.2019.03.004

Acromioclavicular joint (ACJ) injury is a common shoulder injury. There are various techniques of ACJ reconstruction. Superficial infection after ACJ reconstruction is not an uncommon complication. However, osteomyelitis post ACJ reconstruction has never been highlighted as a possible complication. Our patient is a 31-year-old male who sustained a Rockwood 5 ACJ dislocation and had anatomical ACJ reconstruction with autogenous gracilis and semitendinosus graft. Our technique involved the anatomical reconstruction of the ACJ and the coracoclavicular ligament with the usage of two bioscrews and the temporary stabilisation of the ACJ with two k-wires. As in any orthopaedic surgery, infection is often disastrous especially when the surgery involves implants. It can be disastrous with high morbidity to the patient as well as a costly complication to treat. Therefore, we wish to highlight this case as despite its rarity, osteomyelitis can be devastating to the patient and should be prevented if possible.

Morphometric analysis and surgical adequacy of palmaris longus as a tendon graft. A systematic review of cadaveric studies

Yammine K, Erić M

Surg Radiol Anat, 2020 Mar;42(3):259-267.

PMID: 31741040 DOI: 10.1007/s00276-019-02381-x

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.

PMID: 24276110

Intra-articular haemangioma is a rare and uncommon condition that sometimes presents in infants. The lesion can be a diagnostic challenge, with misdiagnosis often leading to delayed diagnosis and treatment. It is essential to establish and treat the condition early, as intra-articular haemangioma can lead to destruction of the joint and secondary arthrosis. Herein, we report the case of a five-year-old boy who presented with intra-articular haemangioma and discuss the management of his condition.

PMID: 32700619 DOI: 10.1177/2309499020938877

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.

It is very rare indeed in the practice of children's orthopaedics today in Malaysia that the natural history of long bone osteomyelitis is seen. A case is presented where a shoulder abscess in a 3-year-old child developed into septic arthritis of the shoulder and subsequently chronic osteomyelitis of the adjacent humerus. The parents refused active surgical debridement and sequestrectomies. Three years later the child had regenerated a new humerus over the sequestra. Radiographs are presented illustrating the entire natural history of osteomyelitis with the regeneration of a new humerus.

Samsudin OC, Aminuddin BS, Munirah S, Chua KH, Fuzina NH, Isa MR, et al.

Med J Malaysia, 2004 May;59 Suppl B:15-6.

PMID: 15468796

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.

The comparison between the different generations of autologous chondrocyte implantation with other treatment modalities: a systematic review of clinical trials

Samsudin EZ, Kamarul T

Knee Surg Sports Traumatol Arthrosc, 2016 Dec;24(12):3912-3926.

PMID: 26003481

PURPOSE: This paper aims to review the current evidence for autologous chondrocyte implantation (ACI) generations relative to other treatment modalities, different cell delivery methods and different cell source application.

METHODS: Literature search was performed to identify all level I and II studies reporting the clinical and structural outcome of any ACI generation in human knees using the following medical electronic databases: PubMed, EMBASE, Cochrane Library, CINAHL, SPORTDiscus and NICE healthcare database. The level of evidence, sample size calculation and risk of bias were determined for all included studies to enable quality assessment.

RESULTS: Twenty studies were included in the analysis, reporting on a total of 1094 patients. Of the 20 studies, 13 compared ACI with other treatment modalities, seven compared different ACI cell delivery methods, and one compared different cell source for implantation. Studies included were heterogeneous in baseline design, preventing meta-analysis. Data showed a trend towards similar outcomes when comparing ACI generations with other repair techniques and when comparing different cell delivery methods and cell source selection. Majority of the studies (80 %) were level II evidence, and overall the quality of studies can be rated as average to low, with the absence of power analysis in 65 % studies.

CONCLUSION: At present, there are insufficient data to conclude any superiority of ACI techniques. Considering its two-stage operation and cost, it may be appropriate to reserve ACI for patients with larger defects or those who have had inadequate response to other repair procedures until hard evidence enables specific clinical recommendations be made.

LEVEL OF EVIDENCE: II.

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.

Stability of cervical spine after one-level corpectomy using different numbers of screws and plate systems

Rosli R, Abdul Kadir MR, Kamarul T

Proc Inst Mech Eng H, 2014 Apr;228(4):342-9.

PMID: 24622982 DOI: 10.1177/0954411914527074

Anterior corpectomy and reconstruction using a plate with locking screws are standard procedures for the treatment of cervical spondylotic myelopathy. Although adding more screws to the construct will normally result in improved fixation stability, several issues need to be considered. Past reports have suggested that increasing the number of screws can result in the increase in spinal rigidity, decreased spine mobility, loss of bone and, possibly, screw loosening. In order to overcome this, options to have constrained, semi-constrained or hybrid screw and plate systems were later introduced. The purpose of this study is to compare the stability achieved by four and two screws using different plate systems after one-level corpectomy with placement of cage. A three-dimensional finite-element model of an intact C1-C7 segment was developed from computer tomography data sets, including the cortical bone, soft tissue and simulated corpectomy fusion at C4-C5. A spinal cage and an anterior cervical plate with different numbers of screws and plate systems were constructed to a fit one-level corpectomy of C5. Moment load of 1.0 N m was applied to the superior surface of C1, with C7 was fixed in all degrees of freedom. The kinematic stability of a two-screw plate was found to be statistically equivalent to a four-screw plate for one-level corpectomy. Thus, it can be a better option of fusion and infers comparable stability after one-level anterior cervical corpectomy, instead of a four-screw plate.

PMID: 10968190

We studied 95 patients who underwent knee Arthroscopy under local anaesthesia between JANUARY 1995 till 1997. Materials used were 1% Xylocaine and 0.25% Bupivacaine of 20 mls each combined with midazolam 2 mg and IV pethidine 30 mgm for sedation. The patients were attached to monitors (pulse Oxymeter, ECG and BP and pulse recorders) and blood less field was created using a tornquet. The procedures lasted about 45 minutes. 90 out of 95 patients completed the procedures successfully without any complications. 2 developed respiratory embarrassments and were intubated and ventilated. 3 procedures abandoned and converted to general anaesthesia. The range of procedures done include meniscectomy, meniscal repair, synovial biopsy, debridement for osteoarthrosis, shaving of osteophytes, drilling of cartilage and bones and removal of loose bodies. This study is to show that knee arthroscopy under LA is a safe alternative in hospitals where GA time is limited.
