Introduction: Surgical treatment for indicated spinal metastases cases is an option to improve patients' outcomes. Local data in analysing the potential of patients' improvement after surgical treatment are limited. We intend to review the clinical outcomes of surgeries performed for cancer patients who were diagnosed with spinal metastases. We aim to identify factors associated with improved spinal pain, neurological deficit and patient survival.

Material and methods: The medical records of 51 patients who were diagnosed with thoracolumbar spinal metastatic tumour and underwent palliative single-stage posterior approach spinal surgery between June 2015 and June 2022 were recruited retrospectively. Patient demographic data, pre-operative and post-operative pain scores, neurological assessment and survival duration were collected from the medical records. Radiological findings were studied using respective imaging and reports.

Results: The mean age was 57.5 years, and the median survival was nine months after the surgical treatment. The post-operative pain improvements were statistically significant at two weeks (VAS improved from 5 to 2), and three months follow-up VAS was one (p<0.001 and p=0.009, respectively). At initial presentation, patients with a single-level spinal involvement had higher VAS compared to multiple spinal metastases (p=0.018). A total of 18 (35.3%) patients had improved one or more ASIA grades, of which eight (15.7%) of them had gain of ambulatory function (p<0.001). Twenty-seven (52.9%) patients were ambulatory post-operative. The slow growth type of primary carcinoma, post-operative ambulatory ability, and the absence of perioperative morbidity were factors associated with favourable survival duration (p=0.006, p<0.001 and p<0.001, respectively). Synchronous visceral metastases adversely affected the survival duration (p=0.008).

Conclusion: Single-stage posterior decompression and stabilisation improved the clinical outcomes of spinal pain and neurological deficit in metastatic spinal tumours. Type of primary tumour, visceral metastasis, perioperative morbidity, and post-operative ambulatory status significantly impact post-operative survival duration.

A 54-year-old gentleman with underlying hypertension and congestive cardiac disease was diagnosed with left lower limb necrotizing fasciitis following commencement of oral dabigatran. Small bruises on the limb progressed to full-blown sepsis. The calculated perioperative risk for surgery was unfavourable. Immediate diagnosis combined with targeted medical treatment managed to produce a medical wonder.

Introduction: Multiple reviews of the applicability, cost-effectiveness, and safety of daycare reconstruction of anterior cruciate ligament have been published in French, American, and British setups, but have not been described in our population.

Materials and methods: In this study, 25 patients who underwent Anterior Cruciate Ligament Reconstruction (ACLR) as a daycare surgery in our setup were assessed retrospectively. Post-operatively patients were reviewed for pain, complications, conversion from daycare to inpatients, readmission within two weeks post ACLR and cost-effectiveness.

Results: None of the patients required readmission within two weeks post-operatively, two patients were admitted on request from Surgical Day Care (SDC) to inpatient postoperatively, two patients developed urinary retention. Daycare ACLR was also cost-effective, as shown by cost analysis a reduction of cost by 26.9 %.

Conclusion: Daycare ACLR is safe, feasible, and cost-effective treatment modality for young patients and can provide a substantial cost saving.

Introduction: Recurrence after Giant Cell Tumour (GCT) treatment depends on the type of treatment used. Poly-Methyl-Meth-Acrylate (PMMA) after extended curettage provides structural support and allows for early identification of recurrence but carries a risk of thermal damage to the surrounding healthy tissue. The aim of this study was to compare long-term functional outcomes and complications in patients with GCT around the knee treated with extended curettage and bone grafting or cementation.

Material and methods: All patients with biopsy-proven GCT, involving either the distal femur or proximal tibia, and treated with either curettage with bone grafting (CBG), curettage with bone cementation (CBC), or curettage combined with grafting and cementation (the Sandwich technique) were included. They were further classified according to Campanacci grading. Patients were followed for a minimum of two years, and all complications were recorded.

Results: The three groups showed a statistically significant difference in terms of persistent pain after surgery (p=0.03), development of long-term arthritis (p=0.01), as well as overall complications (p=0.005). There was no significant difference in terms of the overall recurrence rate between each group (p>0.05). For Campanacci Grade II lesions, there was a statistically significant difference in terms of local recurrence (p=0.01), with lower recurrence rates observed after cementation procedures.

Conclusion: The study indicates that the Sandwich technique was associated with a lower rate of complications compared to CBG or CBC. Patients in the CBG group reported persistent pain, while those in the CBC group exhibited early arthritic changes within five years of the index surgery. Although there was no overall difference in recurrence rates, cementation procedures had a significantly lower rate of recurrence in Campanacci Grade II lesions.

Introduction: This study compares the quality of hydroxyapatite in Anadara granosa waste and laying chicken eggshell waste to commercial synthetic hydroxyapatite.

Material and methods: This experimental research included 27 samples of hydroxyapatite derived from clam shell waste (CSW-HAP), hydroxyapatite derived from eggshell waste (ESW-HAP), and commercial synthetic hydroxyapatite, with nine samples of each. The calcination method was used to process clam shell waste and eggshell waste into hydroxyapatite, which was then compared with synthetic hydroxyapatite from Bongros® for calcium and phosphate content. Scanning electron microscopy was used to compare their morphological structures.

Result: The mean calcium levels in the CW-HAP, EW-HAP, and control groups were 41.3±2.9%, 41.5±2.3%, and 39.6±5.0%, respectively. According to One Way ANOVA, there was no significant difference between the CW-HAP or EW-HAP groups and the control group (p=0.49). The mean phosphate levels in the CW-HAP, EW-HAP, and control groups were 8.1±1.2%, 8.1±1.3%, and 9.4±2.0%, respectively. The results were also not significant (p=0.146).

Conclusion: Clam shell waste and eggshells can be an alternative source of hydroxyapatite substitution, as demonstrated by the structural and porous formation of hydroxyapatite obtained from these sources (CW-HAP and EW-HAP) when compared to commercial synthetic hydroxyapatite.

Introduction: The Malaysian Orthopaedic Journal (MOJ) (ISSN 1985-2533 / 2232-111X) is the official publication of the Malaysian Orthopaedic Association (MOA) and the ASEAN Orthopaedic Association (AOA). In May 2007, MOA published the first standalone issue of MOJ with the aim of disseminating new knowledge and providing updates in orthopaedics, trauma and musculoskeletal research. Since then, MOJ has grown significantly, achieving indexing in numerous databases and attaining a 2nd Quartile (Q2) rank in the Scopus database in 2022. This bibliometric analysis aims to explore the trends and distribution of articles published in MOJ.

Materials and methods: Bibliometric data for MOJ was extracted from the SCOPUS database, covering the years from its indexing to 2022. Information such as authors, country, document type, author's keywords, citations, and other parameters were extracted using the bibliometrix package in the R Studio software. The data were then presented in tables and illustrative graphs using the same software.

Results: A total of 305 articles were retrieved from the Scopus database during the study period. Two-thirds of the articles were original articles and review articles. The highest number of citations received by an article is 56, and top ten articles in MOJ were authored by researchers from seven different countries, highlighting the journal's diversity. Despite receiving submissions from various countries, there is minimal collaboration between authors of different countries. Keywords such as "covid-19" and "pandemic" dominate the authors' keyword section due to the once-in-a-life-time COVID-19 which during the study period, resulting in numerous publications related to this issue.

Conclusion: This bibliometric analysis reviews all the articles indexed in the Scopus database and provides insight into the contributors' information and the trends in orthopaedic research. By identifying the lack of collaboration between countries, it is hoped that this analysis can inspire more orthopaedic surgeons and researchers to collaborate and produce high-quality publications.

Introduction: Post-operative urinary retention (POUR) is a common complication after total knee arthroplasty (TKA) and may result in severe complications such as urinary tract infection and deep joint sepsis, leading to prolonged hospital stay and increased medical costs. Hence a retrospective study was performed to identify the incidence and modifiable factors associated with POUR after elective TKA in Asian patients with the aim to prevent POUR and its undesirable consequences.

Materials and methods: The medical records of 496 consecutive patients who underwent elective TKA between 1 August 2017 and 30 July 2018 were reviewed. There were 154 male (31.0%) and 342 female (69.0%) patients with an average age of 68 years old. The incidence of POUR was analysed with respect to various modifiable and non-modifiable risk factors, including patient demographics, medical comorbidities, duration of surgery, type of intra-operative anaesthesia and post-operative analgesia and early initiation of physiotherapy using univariate and multivariate analyses.

Results: A total of 120 (24.2%) of the 496 patients who underwent elective TKA developed POUR. The odds of a patient with patient-controlled analgesia (PCA) and peripheral nerve block (PNB) developing POUR were 4.2 times and 4.7 times that of a patient without PCA and PNB, respectively. Age, male gender and type of anaesthesia were not found to be significant.

Conclusion: In our study population, the incidence of POUR after elective TKA was 24% with major modifiable risk factors being associated with the use of PCA and PNB as post-operative anaesthesia. POUR can have deleterious effects thus alternative post-operative analgesia should be considered.

Shoulder arthroscopy is an increasingly common procedure. Pneumothorax post-shoulder arthroscopy is a rare complication. Our aim is to highlight a case report of pneumothorax post-shoulder arthroscopy and to conduct a literature review to evaluate the possible risk factors. We report the case of a 75-year-old male non-smoker, who underwent right shoulder arthroscopy without regional anaesthesia in the left lateral position and subsequently suffered a pneumothorax post-operatively. A PubMed Medline and Cochrane database search was carried out, and 32 articles were identified and thoroughly reviewed. Overall, among the articles that propose a mechanism, 75% (9/12) consider the pathogenesis to be multifactorial. The exact mechanism is currently unknown. Awareness of this complication and timely recognition are important to prevent life-threatening sequelae. Surgeons should maintain a low threshold for obtaining diagnostic plain radiographs in the event of clinical suspicion.

Introduction: Bony surface cleaning using a pulse lavage device (PLD) is essential for modern cementation of hip and knee arthroplasties. This costly single-use device is a medical waste and unaffordable for some patients. Reprocessing is a worldwide standard strategy to solve this problem. To determine the technical properties and biological safety of a reprocessed PLD handpiece and compare its performance under different power supplies.

Materials and methods: Eight brand-new disposable PLDs were tested for baseline technical properties (flow rate, pulse frequency, and peak pressure). Thereafter, they were reprocessed and retested for 10 rounds using two different power supplies. An adenosine triphosphate (ATP) swab test was performed on the PLD accessory parts after cleansing and disinfection. Passed-through isotonic sodium chloride solution ejected from the reprocessed PLD underwent aerobic bacterial culture. The unit costs of production were analysed.

Results: The mean flow rate of the disposable PLD (1.5±0.1 L/min) was less than that of reprocessed PLD using DC15V battery (2.5±0.3 L/min, p<0.001) and AC/DC15V3A adapter (6.1±0.4 L/min, p<0.001). The mean pulse frequency and peak pressure of the disposable PLD and reprocessed PLD using DC15V battery were not different (18.5±0.8 vs 18.8±2.5 Hz, p=0.155 and 0.37±0.04 vs 0.38±0.03 N/mm2, p=0.640, respectively), but were lower than those using AC/DC15V3A adapter (47.0±2.7 Hz, 0.45±0.03 N/mm2, p<0.001). All ATP swab tests, and aerobic fluid cultures yielded negative results. The total cost of reprocessing was 10% of disposable PLD.

Conclusion: A disposable PLD handpiece can be reprocessed without deteriorating its technical properties and used with either retrieved DC15V battery or AC/DC15V3A adapter for the power supply. As the biological safety of reprocessed and disposable PLDs was comparable, it may be clinically utilised with 90% cost reduction.

Introduction: Post-trauma patients are at risk of developing symptoms of post-traumatic stress disorder (PTSD) and major depression. The primary goal of this study is to estimate the prevalence of PTSD and depression symptoms in patients who have been hospitalised for the treatment of physical trauma. Additionally, we wanted to compare the prevalence of PTSD or depression symptoms alone versus PTSD associated with depression symptoms, in orthopaedic post-trauma patients.

Materials and methods: This study had involved orthopaedic post-trauma patients in the orthopaedic ward and clinic of Hospital Tuanku Jaafar (HTJ), Seremban, Malaysia, using an online questionnaire, which consist of English and Malay language. We then determined the prevalence of depression and PTSD symptoms in orthopaedic post-trauma patients and compared this prevalence to the severity of the injuries sustained and any association between PTSD and depression symptoms.

Results: Only 12.9% of the participants are likely to have post-traumatic stress disorder (PTSD) symptoms and 43.3% of participants have depression symptoms. There is no significant association between patient demographics and severity of the injuries with the prevalence of post-traumatic stress disorder (PTSD) and depression symptoms. However, of those deemed likely to have PTSD, 93.5% of them had both post-traumatic stress disorder (PTSD) symptoms as well as depressive symptoms.

Conclusion: Only a few of the participants are likely to develop post-traumatic stress disorder (PTSD) while almost half of the participants are likely to have developed depression. Physicians caring for trauma patients should screen them for early symptoms of PTSD and depression and treat them accordingly.
