    We are all aware that there has been a dramatic increase in the number of anterior cruciate ligament (ACL) reconstructions that are carried out here in Malaysia as well as around the world. The numbers of ACL injuries have undoubtedly increased over the years with greater participation of young adults in sporting activities. However it is not certain whether the increase in the numbers of reconstructions can be accounted for by the increasing numbers of ACL injuries. Without doubt commercial interests as well the influence of the biomedical companies have a role to play. In the past the rationale for surgical treatment of an ACL tear was that the ACL is vital for knee function and that in the long term ACL deficiency will lead to more injuries of the meniscus and more degeneration of the joint. This belief was prevalent because the natural history of an ACL deficient knee and the ultimate outcome of reconstruction of the ACL were both not known. However in recent years a substantial amount of research has been published, which has elucidated the natural history of ACL deficient knees as well as the long term outcome of reconstruction of the ACL.

    INTRODUCTION: The awareness of under-representation of female surgeons in orthopaedics has been increasing in this decade. We aim to investigate the reasons why female surgeons chose orthopaedic, the barriers that possibly hinder female surgeons into orthopaedics and analyse the obstacles that they encountered in their career in Malaysian context.

    MATERIALS AND METHODS: A total of 101 registered female orthopaedic surgeons registered with the Malaysian Medical Council, during the period 1980 to 2020, were contacted for a cross-sectional survey, consisting of thirty-four questions on their experience in the orthopaedic career. Eighty-two responses were received (81.2%). Questions in this survey consisted of four sections: (1) demographic details, (2) current clinical practice environment, (3) orthopaedics training experience, and (4) career experience.

    RESULTS: A total of 49% of respondents had subspeciality training, highest in paediatric orthopaedic (30%). Enjoyment of manual tasks (64.6%) and professional satisfaction (64.6%) were the top reasons for choosing orthopaedic as a career. Primary barriers to orthopaedic were physical strength required (56.0%) and public gender bias (52.4%). Twenty-eight percent reported gender discrimination in career opportunities while 60% reported similar in daily work. Thirty-three percent reported verbal and 11% physical sexual harassment in their career. Forty-four percent of respondents reported benefits as female orthopaedic surgeon in their work.

    CONCLUSION: The reasons for Malaysian female orthopaedic surgeons to choose orthopaedic as their career and the barriers perceived to hinder other females from choosing orthopaedics were similar to reports worldwide with no exception to gender discrimination and sexual harassment. The support given by male colleagues to married female surgeons marked a unique phenomenon in Malaysian culture.

    Introduction: Lower limb amputations have a profound impact on the quality of life (QoL) of the patients. This study was done to assess the QoL of patients with transtibial (below-the-knee) amputations (TTA) and transtibial amputees fitted with prosthesis.

    Material and Methods: A case-control study of patients who had undergone TTA from 2015 to 2018 was conducted in Raja Isteri Pengiran Anak Saleha Hospital (RIPAS). Complete data was available for 30 subjects and it was compared with 30 diabetic, non-amputee patients matched for age and gender. QoL was assessed using the RAND 36-Item Health Survey (SF-36) and the functional outcome of prosthesis-fitted transtibial amputees was assessed using the Houghton Scale.

    Results: Almost all cases of TTA were a result of vascular problems related to diabetes and chronic renal disease (n=29; 97%). Eighteen (60%) participants were fitted with prosthesis and 15 (50%) reported having phantom pain. QoL of participants was found to be significantly lower than that of age and sex-matched diabetic non-amputees with regards to physical functioning, role limitation due to physical health, emotional well-being, social functioning, and bodily pain. The mean Houghton Score for participants fitted with prosthesis was 4.89 (SD= 2.83) suggesting low functional outcome.

    Conclusion: TTA has a negative impact on the QoL of patients, especially in terms of functionality. The availability of prosthesis does not significantly improve the quality of life except in the physical functioning domain. Emotional well-being should be emphasised more in the rehabilitation process as this study found poor emotional well-being among participants.

    Gouty arthritis commonly affects peripheral joints and is associated with hyperuricaemia. Spinal manifestations of gouty arthritis are not common, and majority of published articles worldwide were case reports. This is a case report of spinal gouty arthritis that presented with spinal vertebrae destruction and cauda equina syndrome. The magnetic resonance imaging (MRI) showed destruction of L5/S1end plates with cystic collection mimicking infective changes. The tissue histological examination confirmed presence of urate crystal needles that displayed negative double refraction on light microscopy. Spinal gouty arthritis is part of the differential diagnoses in gouty arthritis patients.

    BACKGROUND: Monteggia fracture-dislocation is rare in children. Various reports attest to its rarity, while recording the many variant of this injury. It is, therefore, easy to miss the diagnosis in the absence of proper clinical examination and radiographs.

    CASE REPORT: This report highlights two rare variants of Monteggia fracture-dislocation seen in children. The first case was a 12-year old girl alleged to have fallen from a 15- feet tall tree and sustaining a combined type III Monteggia injury with ipsilateral Type II Salter-Harris injury of distal end radius with a metaphyseal fracture of the distal third of the ulna. The second case was a 13-year old who had sustained a closed fracture of atypical Type I Monteggia hybrid lesion, in a road traffic accident.

    CONCLUSION: This report highlights the rare variants of Monteggia fracture dislocation which could have been missed without proper clinical examinations and radiographs.

    INTRODUCTION: The purpose of this study is to determine the validity, reliability, and responsiveness of the Malay Shoulder Pain and Disability Index (M-SPADI) in Malay speakers suffering from shoulder pain.

    MATERIALS AND METHODS: The M-SPADI, the Numerical Rating Scale (NRS), and measurements of shoulder active range of motion (AROM) were completed by 140 patients with shoulder pain (68 with rotator cuff pathology and 72 with other shoulder pathology). Thirty-four patients were retested for test-retest reliability with M-SPADI after an average of 9.2 days. M-SPADI was performed on twenty-one individuals three months after completing treatment for rotator cuff disorders to assess response.

    RESULTS: The results of exploratory factor analysis revealed a bidimensional structure for M-SPADI. M-SPADI disability score was significantly greater in patients with rotator cuff pathologies (median = 31.87, IQR 82.50) than in patients with other shoulder pathologies (median = 20.00, IQR 23.84). In multi-group factor analysis, measurement invariance revealed no significant difference between the two groups (p>0.05). There was a significant positive correlation between M-SPADI and NRS (Pain = 0.86, Disability = 0.75, Total = 0.82, p=0.005), and a significant negative correlation between M-SPADI and shoulder AROM (Pain = -0.34 to -0.67, Disability =-0.44 to -0.73, Total =0.43 to -0.72, p=0.005). M-SPADI had a high degree of internal consistency (Cronbach's 0.92 for pain and 0.95 for disability). Test-retest reliability was moderate to excellent (ICC Pain = 0.84, ICC Disability = 0.78, ICC Total = 0.81, p=0.001), and the smallest detectable change ranges (Pain = 8.74, Disability = 3.21, Total = 3.83) were less than the minimal detectable change ranges (Pain = 21.57, Disability = 6.82, Total = 8.79). The area under the receiver operating characteristic curve (AUC) for M-SPADI was greater than 0.90 (Pain = 0.99, Disability = 0.94, Total = 0.96).

    CONCLUSION: The M-SPADI has established construct validity, internal consistency, test-retest reliability, and responsiveness. The M-SPADI is a reliable and valid instrument for evaluating shoulder pain among Malay-speaking individuals. In addition, the M-SPADI disability subscale may be useful for monitoring functional score changes in patients with rotator cuff pathology.

    Introduction: This study was designed to produce a validated and reliable Malay version of the Identification of Functional Ankle Instability (IdFAI-M) questionnaire.

    Materials and method: The cross-cultural adaptation was conducted based on standard guidelines to produce the Malay version of the Identification of Functional Ankle Instability (IdFAI-M) questionnaire. The reliability and validity testing were then performed among one hundred and twenty-three physically active University of Malaya students. Among them, twenty-two students also participated in the second return of the questionnaire over a two-week interval, which was then evaluated for test-retest reliability testing.

    Results: The content validity for item-level (I-CVI) and Kappa values for all items were more than 0.7, respectively and the all scales-level (S-CVI) values were 0.983 (consistency), 0.967 (representativeness), 1.00 (relevance) and 0.983 (clarity). The questionnaire also demonstrated excellent reliability with an intraclass correlation coefficient (ICC2.1) above 0.850 for all items. It was observed that outer loading of most items were more than the minimum acceptable value (0.7). Fornell-Larcker criterion demonstrate all values for each reflective construct was larger than the correlations with other constructs, indicating discriminant. The cross-loading values of each item has shown a weak correlation with all other constructs, except for the one to which it was theoretically associated.

    Conclusions: The Malay version of the IdFAI (IdFAI-M) is a reliable and valid instrument that can be readily utilised to subjectively assess ankle instability.

    Introduction: Malunited intertrochanteric fractures are frequently seen in rural populations as they tend to go in for native treatment with traditional bone setters. The resulting Coxa vara is associated with shortening, abductor weakness, limp and decreased range of movement of the affected hip. The aim of this study was to evaluate the role of Valgus osteotomy with Dynamic hip screw (DHS) fixation in the management of these fractures and to evaluate the functional outcome using the Harris hip score.

    Materials and Methods: Fifteen patients with malunited intertrochanteric fractures who presented between January 2011 to January 2013 were managed by Valgus osteotomy with DHS fixation and were followed-up for a minimum period of three years.

    Results: There was a male preponderance seen in our study with the right hip being more commonly affected. The most common mode of injury was slip and fall followed by road traffic accidents. The duration of native treatment ranged from seven to 12 weeks and the time of presentation to the hospital ranged from four to nine months following injury. Pre-operative mean neck shaft angle was 94.73° while it was 134.6° post-operatively. The mean pre-operative Harris hip score was 72.33 and it was 91 at follow-up. All patients were happy with the procedure and the functional outcome.

    Conclusion: Valgus osteotomy with DHS fixation is an effective procedure in the management of malunited intertrochanteric fractures. It corrects the limb length discrepancy, restores the decreased neck shaft angle, improves range of movement, restores the integrity of the abductor mechanism of the hip and gives good functional results.

    Coronal malalignment due to malrotated trochanteric nail placement in femoral fracture fixation has never been reported. We present a case of a femoral segmental fracture fixed with a trochanteric nail, with a malrotated placement resulting in a valgus malaligned nail and femur, associated with a rotational malalignment. Knowledge of the modern nail design with proper intra-operative precautions, would avoid this underestimated technical error.

    The objective of this study was to assess the rate of screw cut out in elderly patients treated with the dynamic hip screw and the relationship to the Tip Apex Distance (TAD). This is a retrospective radiological evaluation of 100 cases of elderly patients with intertrochanteric fracture treated with dynamic hip screw fixation surgically treated between 1998 and 2002. The incidence of screw cut out was assessed and correlation of risk of cut out with the TAD was assessed. The rate of screw cut out was 9.0% and the average length of time to screw cut out was 3.8 months (range, 1 to 6 months) postoperatively. The incidence of screw cut out increased significantly when the TAD was 20 mm or more. The screw cut out rates were 2.9%, 20.0%, 30.8%, 50% and 100% for TAD of 20-24 mm, 25-29 mm, 30-34 mm, 35-44 mm and > 45 mm respectively. Overall, a TAD of 20mm or more was associated with a statistically significant screw cut out risk in this Malaysian population

    The treatment of fractures in osteopetrosis can be complicated and difficult. We describe the use of an industrial grade tungsten carbide drill bit in the treatment of one of these complex fractures. An industrial grade tungsten carbide drill bit was used to fashion a medullary canal in the surgical treatment of a left peri-implant fracture of the neck of femur in a patient with osteopetrosis. The patient was successfully treated with a hemiarthroplasty with good functional outcomes. A tungsten carbide drill bit serves as an effective and safe option in the treatment of osteopetrotic femoral neck fractures.

    Interlocked intramedullary nailing is accepted as the gold standard for femoral shaft fractures. However for Winquist type I and II femoral fractures at the isthmus region, unlocked intramedullary nailing (Küntscher nailing) is still a good option. We performed a retrospective study on 86 patients with a total of 88 femoral shaft fractures around the isthmus that presented at our institution between 1 January 1988 and 31 August 2003. All patients (84.1% Winquist type I and 15.9% Winquist Type II fractures) were treated with unlocked intramedullary nail. The average time to union was 16 weeks with 97.7% rate of union. There were two cases (2.3%) of infection and non-union each. Overall results were comparable to standard interlocking intramedullary nailing. We conclude that unlocked intramedullary nailing is a good treatment option for Winquist Type I and II femoral fracture around the isthmus with its good union rate and minimal complications.

    Bone lengthening with distraction osteogenesis involves prolonged application of an external fixator frame. Qualitative and quantitative evaluation of callus has been described using various imaging modalities but there is no simple reliable and readily available method. This study aims to investigate the use of a densitometer to analyze plain radiographic images and correlate them with the rate of new bone formation as represented by the bone healing index. A total of 34 bone lengthening procedures in 29 patients were retrospectively reviewed. We used an X-Rite 301 densitometer to measure densities of new callus on plain radiographs taken at 4 and 8 weeks after surgery. Patients aged below 16y had significantly lower BHIs indicating faster bone healing and shorter duration of treatment. The ratio of radiographic densities between centre and edge of the new bone measured from plain radiographs taken at 8 weeks correlated positively with the eventual BHI of the patient. This method provides a simple and easy way to predict the rate of bone healing at an early stage of treatment and may also allow remedial action to be taken for those with poor progress in bone formation.

    We evaluated the efficacy of a cement gun to improve the depth of cement penetration in total knee arthroplasty. Ninety-one consecutive patients from two hospitals were recruited for this study. For Group I cement was applied to the tibial baseplate and the proximal tibia with fingers. Group 2 had similar application of cement to the tibial baseplate but cement was pressurized into the proximal tibia using a cement gun.. The knee was kept extended until the cement hardened. Standard post-operative x-rays were reviewed to assess cement penetration into the proximal tibia. The mean cement penetration was 2.1 mm in Group 1 and 3.1 mm in Group 2 and the difference was statistically significant. The use of the cement gun improves cement penetration into the proximal tibia and facilitates early stability of the implant fixation to the bone.

    Disc herniation is one of most common causes of spine surgery. Because of the presence of posterior longitudinal ligaments, disc fragments often migrate into the ventral epidural space. A posterior epidural herniation of a disc fragment is a rare occurrence. We report two cases of posterior migrated disc fragments, with, radiological and clinical findings. Because of the rarity of a posterior migration of the intervertebral disc fragments, a differential diagnosis can be challenging. This painful syndrome associated with neurological lower limb deficits can be confused initially, with other posterior epidural space-occupying lesions such as tumours, abscess or hematomas. A gadolinium-enhanced MRI scan is the gold standard for a correct diagnosis. Early surgical decompression of the spine with a posterior approach remains the optimal technique in ensuring the best possible outcome for the patient.

    Lumbar decompressive laminectomy is a standard treatment for degenerative lumbar spinal stenosis, but in some cases, can lead to iatrogenic spondylolysis and delayed segmental instability. Iatrogenic spondylolysis occurs in most cases in pars interarticularis, but rare cases have also been reported, pediculolysis in pedicle and laminolysis in lamina. Minimally invasive spine surgery (MIS) is known to have a low risk of developing these iatrogenic spondylolyses, and unilateral biportal endoscopy is the MIS that has been drawing attention. We present a case of a 72-year-old female who was diagnosed with L4-5 unstable non-isthmic spondylolisthesis and severe right central disc extrusion 10 weeks after UBE assisted unilateral laminotomy for bilateral decompression (ULBD) at the consecutive segments of L3-4 and L4-5. Pre-operative imaging studies revealed severe central stenosis without spondylolisthesis at L3-L4 and L4-L5 along with L4-L5 facet tropism. She was managed by anterior lumbar interbody fusion and cement augmented pedicle screw fixation, which resulted in the complete resolution of her clinical and neurologic symptoms.

    Interlocking intramedullary nailing is suitable for comminuted femoral isthmus fractures, but for noncomminuted fractures its benefit over unlocked nailing is debatable. This study was undertaken to compare outcomes of interlocking nailing versus unlocked intramedullary nailing in such fractures. Ninety-three cases of noncomminuted femoral isthmus fractures (Winquist I and II) treated with interlocking nailing and unlocked nailing from 1 June 2004 to 1 June 2005 were reviewed; radiological and clinical union rates, bony alignment, complication and knee function were investigated. There was no statistical significant difference with regard to union rate, implant failure, infection and fracture alignment in both study groups. Open fixation with unlocked femoral nailing is technically less demanding and requires less operating time; additionally, there is no exposure to radiation and cost of the implant is cheaper. We therefore conclude that unlocked nailing is still useful for the management of non-comminute isthmus fractures of the femur.

    Purpose: To evaluate the usefulness of ultrasound guidance in percutaneous needle biopsy for musculoskeletal tumours.
    Methods: Forty-five consecutive patients underwent ultrasound-guided needle biopsy. An additional group of 50 patients who underwent needle biopsy without ultrasound guidance was retrospectively selected as historical control. The sample was considered adequate when a diagnosis can be made, and diagnostic when the diagnosis is similar to the final report based on the excised tumour.
    Results: Adequacy of the biopsy samples was 84% in ultrasound-guided group as compared 76% in the group with no ultrasound guidance. Diagnostic accuracy was 64% in the ultrasound-guided group and 52% in the group without ultrasound guidance. Both of these differences were not statistically significant.
    Conclusions: Ultrasound guidance did not provide a significant advantage in the biopsy of musculoskeletal tumours. Diagnostic accuracy seems to improve with the use of larger 14 gauge biopsy needle but further evaluation is necessary.
