Rusdi A, Shahrulazua A, Siti HT, Nizlan NM

Clin Ter, 2014;165(1):e28-34.
PMID: 24589957 DOI: 10.7471/CT.2014.1668

AIMS: To evaluate the functional outcomes of a delayed (>6 months post-injury) and combined reconstruction of grade III posterior cruciate ligament (PCL) and grade III posterolateral corner (PLC) deficiencies.
PATIENTS AND METHODS: Between March 2006 and October 2009, a delayed surgery consisting of arthroscopically-assisted PCL reconstruction and open reconstruction of the PLC was performed on 19 men and 2 women (average age, 29 years). The mean time-to-surgery was 18 months (range, 7-51 months) and duration of follow-up was 22 months (range, 12-48 months). Postoperatively, patients were evaluated using Lysholm score, Tegner activity score, and International Knee Documentation Committee (IKDC) subjective and objective scores.
RESULTS: At the final follow-up, majority of the knees (61.9%) achieved either normal or nearly normal rating objective IKDC score. The means of IKDC subjective score, Lysholm score and Tegner activity level were 62.09, 74.35 and 5.14 respectively. One patient was able to participate in competitive sport, 5 patients were able to be involved in recreational sports for at least 5 times per week, 10 patients were able to perform heavy labour and recreational sports for at least twice weekly, 4 patients were able to engage in moderately heavy labour work and one patient was only able to perform light labour work. There was no significant statistical association found between the time-to-surgery and the final patients' outcomes.
CONCLUSIONS: A delayed simultaneous reconstruction of chronic grade III PCL and PLC deficiencies can restore sufficient function for standard daily and recreational sports activities to the patients.
Fulltext Osteomyelitis post acromioclavicular joint reconstruction

Yeak RD, Daud H, Nizlan NM

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

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.

J Orthop Surg (Hong Kong), 2020 7 24;28(2):2309499020938877.
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.
Fulltext An Unusual Case of Chronic Partial Quadriceps Tear in a Child: A Case Report

Yeak RDK, Yap YY, Nizlan NM

JNMA J Nepal Med Assoc, 2020 Dec 31;58(232):1083-1085.

Quadriceps tendon rupture usually occurs in adults and is rare in children. A six-year-old boy was playing at home and had a fall. He was unable to extend his right knee but there was no gap felt over the patella tendon or quadriceps. He was first seen by a family doctor and presented late to the surgeon three months after the injury. Radiographs and ultrasound were performed. The magnetic resonance imaging confirmed the findings of partial quadriceps tear. The patient was put in a cylinder case with the knee in extension for two months. Six months post-injury, he regained full range of motion without any complications. We present an unusual case of partial quadriceps tear in an otherwise healthy six-year-old boy that was treated successfully despite a delayed presentation. Besides a high index of suspicion, magnetic resonance imaging is a good modality to detect partial quadriceps tear in children.

Malays Orthop J, 2017 Jul;11(2):30-35.
PMID: 29021876 MyJurnal DOI: 10.5704/MOJ.1707.012

Introduction: The aims of this study are to define the coracoid process anatomy in a Malaysian population, carried out on patients in Hospital Serdang with specific emphasis on the dimension of the base of coracoid process which is important in coraco-acromial (CC) ligament reconstruction, to define the average amount of bone available for use in coracoid transfer, and to compare the size of coracoid process based on gender and race, and with findings in previous studies. Materials and Methods: Fifteen pairs of computed tomography (CT) based 3-dimensional models of shoulders of patients aged between 20 to 60 years old were examined. The mean dimensions of coracoid were measured and compared with regards to gender and race. The data were also compared to previously published studies. Results: The mean length of the coracoid process was 37.94 ± 4.30 mm. Male subjects were found to have larger-sized coracoids in all dimensions as compared to female subjects. The mean tip of coracoid dimension overall was 19.99 + 1.93mm length × 10.03 + 1.48mm height × 11.63 + 2.12mm width. The mean base of coracoid dimension was 18.96 + 3.71mm length × 13.84 + 1.76mm width. No significant differences were observed with regards to racial denomination. The overall coracoid size measurements were found to be smaller compared to previous studies done on the Western population. Conclusion: This study may suggest that Malaysians have smaller coracoid dimension compared to Caucasians. The findings further suggest that the incidence of coracoid fracture and implants pull out in Malaysian subjects may be higher.

Shoulder pain is a common complaint seen in the orthopedic clinic. Here, we report a rare case of primary extranodal ileocecal with exceedingly rare right shoulder deltoid non-Hodgkin's lymphoma (NHL). A 67-year-old female presented with abdominal swelling for four months associated with loss of appetite, loss of weight, and night sweats. Abdominal contrast-enhanced CT and cecal biopsy confirmed the diagnosis of ileocecal NHL. A right hemicolectomy was performed, and the patient completed six cycles of chemotherapy. The patient developed right shoulder pain with swelling three months later and was diagnosed with a relapse ileocecal lymphoma with dissemination to the right deltoid muscle after a repeat positron emission tomography scan. Clinicians need to consider NHL as a differential diagnosis in evaluating shoulder pain or swelling even though it is exceedingly rare. A partial or non-response to chemotherapy with dissemination to skeletal muscle carries a poor prognosis.

Tan EK, Alias A, Yeak R, Jaafar MS, Nizlan NM

Cureus, 2022 Oct;14(10):e30606.
PMID: 36426341 DOI: 10.7759/cureus.30606

The sural nerve is a commonly encountered anatomical structure in foot and ankle surgeries. Knowledge of its location and course is imperative in performing surgeries within its vicinity to avoid neurological deficits. We herein report a rare anatomical variation of the sural nerve where it trifurcates above the level of the lateral malleolus that was discovered in a patient who underwent internal fixation for a trimalleolar ankle fracture with ipsilateral navicular fracture. This study aimed to raise awareness on a unique anatomical variation of the sural nerve in order to reduce the risk of iatrogenic injury.

INTRODUCTION: Corona Mortis (CMOR) is a term used to describe an anatomical vascular variant of retropubic anastomosis located posterior to superior pubic ramus. We aim to provide sufficient data on the incidence, morphology and mean location of 'crown of death' in Asian population. Other objectives include to assess the relationship between CMOR incidence with gender, race and age.
MATERIALS AND METHODS: This is a cross-sectional cadaveric study involving 164 randomly selected fresh multiracial Asian hemipelves (82 cadavers). Hemipelves were dissected to expose and evaluate the vascular elements posterior to superior pubic rami. Data were analysed using Chi-Square, t-test and with the help of IBM SPSS Statistics v26 software.
RESULTS: CMOR was found in 117 hemipelves (71.3%). No new morphological subtype was found. The mean distance of CMOR to symphysis pubis was 54.72mm (SD 9.35). Based on the results, it is evident that precaution needed to be taken at least within 55mm from symphysis pubis during any surgical intervention. The lack of statistically significant correlation between CMOR occurrence and gender, race and age suggest that the incidence of CMOR could be sporadic in manner.
CONCLUSION: We conclude that CMOR is not just aberrant vessel as the incidence is high and this finding is comparable to other studies. The mean location of CMOR obtained in this study will guide surgeons from various disciplines in Asia to manage traumatic vascular injury and to perform a safe surgical procedure involving the pelvis area.
