The heel and sole possess unique anatomical characteristics that serve a weight-bearing and shock-absorbing function. The heel is particularly vital, as any defects in this area can lead to gait instability. Reconstructing a heel defect presents challenges, as the donor flap must be durable enough to withstand high force loads while also providing protective sensation. Recently, the medial plantar artery flap has been successfully employed for the reconstruction of defective heel pads. This flap offers glabrous skin capable of weight transmission and intact protective sensation. In this report, we present two cases of heel pad loss secondary to chronic diabetic complications and trauma, respectively, which were treated with medial plantar artery flap reconstruction. Both cases were successfully treated, and they showed a good functional outcome.
Primary non-Hodgkin lymphoma arising from the spine is exceedingly rare. Spinal cord compression can be the first presentation of a patient with primary spinal non-Hodgkin lymphoma. Due to its rarity and vague clinical presentation, the diagnosis can be confused with tuberculosis of the spine, a more common disease in this country. We present a case of primary thoracic spine B-cell lymphoma in a 45-year-old lady who presented with spinal cord compression. This case highlights the importance of obtaining histopathological samples for examination and the treating physician should be vigilant on this rare cause of spinal cord compression. Treatment can be initiated promptly once the diagnosis is established as primary spinal non-Hodgkin lymphoma carries a dire prognosis.
Background and objective Femoral neck fractures are relatively rare in young adults, but they result in prolonged loss of function in these patients, thereby placing a huge burden on a country's healthcare and economy. Femoral neck fractures in young adults are normally treated with head salvage surgery. However, primary head replacement surgeries have been gaining traction recently to expedite the recovery of these patients. In this study, we aimed to investigate the outcomes in young patients with femoral neck fractures and factors associated with their complications. Patients and methods Patients with femoral neck fractures who underwent surgery in three tertiary hospitals [Hospital Tengku Ampuan Afzan (HTAA), Hospital Sultan Haji Ahmad Shah (HOSHAS), and Hospital Kuala Lipis] in Pahang state in Malaysia were reviewed and included in this study. The demographic profile of the patients, injury patterns, intervention details, functional outcomes, and complications were analyzed. The comparison between the sociodemographics, clinical assessment, and complication outcomes was analyzed using statistical software. Results The complications were associated with the mechanism of injury, capsulotomy, and type of fixation. A total of 46 patients were included in the study. Most of the patients were found to have severe displacement based on Garden and Pauwels classification. The majority of the patients underwent femoral head salvage surgeries. Almost half of the patients sustained complications and were unable to achieve weight-bearing status at six months postoperatively. Conclusion Despite a relatively short follow-up period in our study, femoral neck fractures in young adults were found to be associated with a high rate of complications. Primary head replacement surgeries should be considered in high-risk patients with femoral neck fractures.
Background and objective Periprosthetic joint infection (PJI) is one of the dreaded complications in patients after arthroplasty surgeries, owing to the risk of morbidity and arduous investigations and management associated with it. Nevertheless, as Malaysia is currently battling against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-induced coronavirus disease 2019 (COVID-19) pandemic head-on, the treatment for other non-life-threatening diseases including PJI has taken a backseat. In this study, we present a case series of 11 patients with PJI who were managed surgically at the largest tertiary hospital in Malaysia and we hope to shed some light on the difficulties we have encountered during this trying period. Patients and methods Patients with PJIs who underwent surgical intervention during the ongoing COVID-19 pandemic (March 1, 2020, to June 30, 2021) were reviewed and included in this study. The demographic profile of the patients, presenting complaints, prosthesis topography, biochemical investigative findings, surgical interventions, and short-term outcomes were summarized. Results A total of 11 patients were treated surgically at Hospital Kuala Lumpur for PJI. Among them, five patients are still awaiting their second-stage surgeries despite the completion of their antibiotic regimes, and they are fit for the procedure. Conclusion The COVID-19 pandemic has wreaked havoc on the treatment of patients with PJI. In a setting with scarce resources, surgeons should strongly consider single-stage revision surgeries for the treatment of patients with PJI.
Introduction Computed tomography pulmonary angiography (CTPA) is the reference investigation of choice to diagnose pulmonary embolism (PE). Nevertheless, the use of CTPA should be weighed against its risks, such as radiation and contrast-induced nephropathy. We aim to assess the yield of CTPA in diagnosing PE at a tertiary centre in Malaysia. We also identify predictive factors associated with the yield of CTPA in this cohort. Methods This was a cross-sectional study involving all patients who had had CTPA done at Hospital Tengku Ampuan Afzan, Kuantan, Malaysia, from January 1, 2021, to November 30, 2021. All patients' records were retrieved and reviewed. CTPA images were retrieved from the Radiology Information System (RIS) and Picture Archiving and Communication System (PACS). They were double-reviewed by the authors, with the initial reports redacted from reporting radiologists to prevent reporting bias. The predictive factors were determined using simple logistic regression and multiple logistic regression. Results A total of 351 CTPAs were reviewed, of which 93 were found to be positive for PE, giving rise to an overall CTPA yield of 26.5%. Upon simple logistic regression, factors such as gender, discipline, history of trauma, presence of COVID-19 infection, and pneumonia were found to be associated with positive CTPA. Upon multiple logistic regression, male patients were found to have a higher chance of positive CTPA results. On the other hand, patients with COVID-19 infection and pneumonia have a lower chance of positive results in CTPA. Conclusion The yield of CTPA in diagnosing PE at our institution was acceptable at 26.5%. Upon multiple logistic regression, patients with COVID-19 infection and pneumonia were more likely to have a negative CTPA result, highlighting the need for clinicians to be more prudent in requesting CTPAs in these patients.
CT pulmonary angiography (CTPA) is the investigation of choice for diagnosing pulmonary embolism (PE). Due to the speed and ease of performing the CTPA scans, more clinicians are becoming overly reliant on them, even for patients without strong suspicion of PE. We conducted a bibliometric analysis on the PubMed database from 1990 to 2022 to investigate the literature on the diagnostic yield of CTPA in the diagnosis of PE. A total of 166 articles were published in 98 journals. The number of publications has steadily increased since 2010 and peaked in 2020. Authors from 24 countries contributed to these publications, with the overwhelming majority emanating from United States of America, totaling 66 articles. The authors' contributions were relatively well spread out, with the top four authors publishing the highest number of articles at six each. When we investigated the collaboration between the authors, we found limited multinational and multi-institutional collaborations on this topic. Therefore, more multinational and multi-institutional collaborations will be valuable in future studies. In conclusion, this bibliometric analysis summarizes the literature on diagnostic yield of CTPA in the diagnosis of PE and sheds light on the future pathway that researchers and institutions can focus on.
Background A soft tissue defect resulting from a diabetic heel ulcer can be difficult to address due to limited reconstructive options and unique local area demand. The medial plantar artery flap is ideal for heel defect coverage as it provides a thick glabrous skin with good sensory feedback. The prerequisite of medial plantar artery flap surgery is a patent medial plantar artery, which is a branch of the posterior tibial artery (PTA). Nevertheless, no feasibility study of the medial plantar artery flap in diabetic patients with vascular insufficiency has been reported so far. We conducted a pilot study with the aim of investigating the patency of the medial plantar artery in diabetic patients with suspected peripheral artery disease to determine the vascular feasibility of the medial plantar artery flap in these patients. Material and methods A pilot study was performed at Sultan Ahmad Shah Medical Centre at International Islamic University Malaysia (IIUM). A total of 15 diabetic patients with suspected vascular insufficiency who had undergone lower limb computed tomography angiography (CTA) from January 2022 to June 2023 were included in this study. All patients were identified via the electronic record system. Lower limb CTA images were retrieved from the Radiology Information System (RIS) and Picture Archiving and Communication System (PACS) and were double-reviewed. Both the posterior tibial artery (PTA) and medial plantar artery (MPA) were assessed for their patency, and the diameter of the lumens was measured if they were patent. Bedside clinical assessments such as palpation of pulses and portable Doppler assessment were evaluated to determine whether they could serve as substitutes for computed tomography angiography (CTA) in assessing the feasibility of medial plantar artery flap using the McNemar test. Results In this study cohort, the medial plantar artery was present in 16 legs and absent in another 14 legs. The largest diameter of the medial plantar artery was 2.5mm (range 0-2.5mm). Palpation of the posterior tibial artery was not optimal for predicting the patency of the medial plantar artery, with a false positive of 21.4% and a false negative of 68.7%. Similarly, a hand-held Doppler assessment of the posterior tibial artery was also ineffective, with a false positive of 64.3% and a false negative of 18.8%. While the medial plantar artery is a continuation of the posterior tibial artery (PTA), PTA patency did not necessarily correlate with medial plantar artery patency. This was demonstrated on CTA assessment, where two legs with absent PTA still have reconstitution, resulting in patency of the medial plantar artery. Additionally, one leg with patent PTA did not have a patent medial plantar artery distally due to calcified vessels. Conclusion This is a first-of-its-kind pilot study attempting to determine the feasibility of medial plantar artery in diabetic patients with vascular insufficiency. The medial plantar artery was present in more than 50% of the investigated lower limbs, paving the way for using the medial plantar artery flap in these patients. Nevertheless, a computed tomography angiogram is essential to determine the patency of the medial plantar artery prior to the flap procedure, as palpation and hand-held Doppler were inadequate to predict the patency of the medial plantar artery in these high-risk patients.
Robotic-assisted hip and knee arthroplasty represents cutting-edge advancements in orthopedic surgery, harnessing robotic technology to enhance precision, improve clinical outcomes, and facilitate intra-operative procedures. In these robotic-assisted surgeries, the robotic systems assist surgeons in planning and executing joint replacement surgeries, thereby facilitating personalized implant positioning and optimizing the fit and alignment of hip and knee implants. Despite the increasing attention garnered by robotic-assisted hip and knee arthroplasty in recent years, a comprehensive bibliometric analysis using the Scopus database has yet to be conducted. This bibliometric analysis reviews the Scopus database from 1961 until 2022 to investigate the literature on the field of robotic-assisted hip and knee arthroplasty. A total of 577 articles that satisfied the selection criteria were included in this review. The majority of the articles focus more on total knee replacement, compared to total hip replacement and unicompartmental knee arthroplasty. The overwhelming majority of the articles were authored by researchers and clinicians from the United States of America (USA) and the United Kingdom (UK). Similarly, most of the articles with the highest number of citations were authored by researchers and clinicians from these regions. This comprehensive bibliometric analysis using Scopus in the domain of robotic-assisted hip and knee replacement has the potential to act as a roadmap for researchers, clinicians, and policymakers, facilitating informed decision-making, promoting collaborative initiatives, and guiding the development of future studies to further advance the field of robotic-assisted hip and knee arthroplasty.
Diabetic foot problems are among the most debilitating complications of diabetes mellitus. These problems incur significant economic costs and reduce quality of life. The integration of thermography technology in the screening and management of diabetic foot problems has been proven to be successful in recent years. By detecting changes in temperature, thermography helps identify early infections and assists in patient monitoring. These early successes have inspired more research and publications in this field. To date, a comprehensive bibliometric analysis of thermography-related research on diabetic foot using the Scopus database has not been conducted. This bibliometric analysis aims to fill this gap by reviewing the Scopus database from its inception until 2023 to examine the literature on thermography-related research on diabetic foot. A total of 342 articles met the selection criteria and were included in this analysis. The number of articles in this field remained low until the 2010s, when there was a sudden surge of interest that prompted numerous publications. Authors from the USA contributed the highest number of articles and had the greatest scholarly impact in this field. Despite the major contribution from the USA, there were numerous collaborations between various countries, underscoring the importance of international collaboration in advancing research and exchanging knowledge.
Intraarticular injection of osteoarthritis knee is one of the treatment options for pain management and delays the need for knee surgery. Various materials have been promoted for the procedure, ranging from corticosteroid to viscosupplement to the more recent autologous biological materials. Despite the increasing attention and interest in regard to the material selection, efficacy, safety, and effect of this intervention, a comprehensive bibliometric analysis using the Scopus database has yet to be conducted. In this bibliometric analysis, we reviewed the Scopus database from 2003 to 2023 to investigate the literature on intraarticular injection for the treatment of knee osteoarthritis. A total of 1,318 articles that satisfied the selection criteria were included in this review. The trend of intervention shows changes since 2006, with corticosteroid injection and hyaluronic acid as the main topics of publication before 2006. However, starting in 2010, there has been a noticeable shift towards biological agents, such as plasma-rich proteins, and autologous materials, including marrow aspiration and stromal vascular fraction. This shift reflects the increasing interest in regenerative medicine and the potential of these newer therapies to provide improved outcomes. The overwhelming majority of the articles were authored by researchers and clinicians from across European countries, the United States of America (USA), and Australia. Similarly, most of the articles with the highest number of citations were authored by researchers and clinicians from these regions. This comprehensive bibliometric analysis using Scopus in the domain of intraarticular injection has the potential to act as a roadmap for researchers, clinicians, and policymakers, facilitating informed decision-making, promoting collaborative initiatives, and guiding the development of future studies to further advance the options of knee intraarticular injection, specifically in the management of knee osteoarthritis.
Introduction With the advancing age of the population, there are an increasing number of patients with geriatric hip fractures. Despite the advancement of surgical knowledge and improvement of implant designs to treat geriatric hip fractures, mortality and morbidity remain high among these frail patients. In conjunction with the COVID-19 pandemic, the collateral damage dealt to these patients remains unknown as scarce resources are funneled to deal with the pandemic. This study is geared to investigate the surgical outcomes of patients with geriatric hip fractures who were admitted during the initial phase of the COVID-19 pandemic. Methods This retrospective study was carried out at Hospital Kuala Lumpur, the largest public hospital in the capital of Malaysia, from March 1, 2020, to March 1, 2021. All patients of age 60 years and above were screened for suitability. Only patients who had undergone surgical intervention during the study period were included in this study. Patients' demographic data, mechanism of injury, waiting time for surgery, type of surgery, complications and ambulatory status were obtained from the medical records. Univariate analysis was performed to determine the factors associated with complications as well as the post-operative ambulatory status of the patients. Results A total of 52 patients were included in this study, with a median age of 72 years. The majority of the patients were Chinese (n=21, 40.4%). This was followed by Malay and Indian (n=14, 26.9% each) and other ethnicity (n=3, 5.8%). More than three-quarters of the patients had a trivial injury such as a fall due to a miss-step (n=16, 30.8%) and slip (n=16, 30.8%) and a fall due to dizziness (n=8, 15.4%). Only 12 patients (23.1%) sustained hip fractures due to trauma. The median time to surgery for these patients was 5 days (interquartile range: 4 days). Most of these patients underwent total hip replacement (n=30, 57.7%). This was followed by unipolar hemiarthroplasty (n=11, 21.2%), bipolar hemiarthroplasty (n=10, 19.2%) and internal fixation (n=1, 1.9%). Among these patients, six of them had documented complications. There were periprosthetic joint infection (n=2, 3.8%), dislocation (n=2, 3.8%), hematoma formation (n=1, 1.9%) and seroma (n=1, 1.9%). Six months after the surgery, most of the patients were able to ambulate, albeit some patients required walking aid such as walking stick and walking frame. Univariate analysis showed that all the factors were not associated with the complications and the post-operative ambulatory status of the patients. Conclusion The incidence of geriatric hip fractures remains high during the COVID-19 pandemic despite the movement control order (MCO) being enforced in Malaysia. With prompt surgical intervention, most of the patients can regain ambulatory status, albeit with a walking aid.
