V-Y Quadricepsplasty for Knee Stiffness Post Total Knee Arthroplasty: A Case Report and Literature Review.

Introduction: Knee stiffness post-total knee arthroplasty (TKA) represents a common and challenging complication. Standard treatment protocols primarily include physical therapy, manipulation under anesthesia (MUA), fibrotic tissue release, lysis of adhesions (LOA), and in refractory cases, revision arthroplasty. However, these interventions often show minimal improvement in refractory cases. This report introduces V-Y quadricepsplasty as an innovative approach for addressing knee stiffness post-TKA, particularly in cases unresponsive to MUA and LOA, without any evidence of prosthetic component malposition or failure. Case Report: We present a case involving a middle-aged woman experiencing persistent knee stiffness post-TKA, unresponsive to both MUA and LOA. Diagnostic evaluations confirmed no malposition or failure of the prosthetic component. The patient underwent a successful V-Y quadricepsplasty, which resulted in significant improvement in her condition. Conclusion: This case underscores the efficacy of V-Y quadricepsplasty in managing knee stiffness post-TKA, especially in cases where traditional treatments such as MUA and LOA are ineffective and there is no evidence of prosthetic component failure or malposition. This approach potentially offers a new avenue for treatment in similar clinical scenarios.

Isolated lateral radial head dislocation in a child: A case report and literature review.

INTRODUCTION: Radial head dislocations in children can result from congenital anomalies, traumatic events, or as part of more complex injuries like Monteggia fractures. These dislocations are rare and may be overlooked unless considered in differential diagnoses. CASE PRESENTATION: We describe a unique instance of a post-traumatic isolated lateral radial head dislocation in a 5-year-old boy with no previous medical concerns. The child presented with persistent pain and limited mobility in the left elbow following an unwitnessed fall at home. Diagnosis was confirmed via radiographs showing the dislocation without associated fractures. Closed reduction under anesthesia was successfully performed. CLINICAL DISCUSSION: This case underscores the importance of a high index of suspicion and thorough imaging in diagnosing pediatric radial head dislocations. Our discussion includes a review of the literature and the clinical approach for managing such injuries, highlighting the specifics of the closed reduction technique used. CONCLUSION: Isolated lateral radial head dislocations, although rare, can occur and are amenable to closed reduction. This case contributes to the limited reports of such dislocations in pediatric patients, emphasizing the need for awareness and precise management strategies to prevent long-term complications.

Cortical Trajectory Versus Traditional Pedicle Screw Trajectory in Open Transforaminal Lumbar Interbody Fusion: Meta-analysis of Complications and Clinical Outcomes.

BACKGROUND: Lumbar degenerative disease imposes a substantial burden on global healthcare expenditures. Transforaminal lumbar interbody fusion (TLIF) utilizing either traditional trajectory (TT) pedicle screws or cortical bone trajectory (CT) pedicle screws have become increasingly common. This meta-analysis evaluates the outcomes and safety of open TLIF with TT compared to CT. METHODS: PubMed, Cochrane, and Google Scholar (pages 1-20) were explored until April 2024. The studied outcomes included complications, revision surgeries, operative room (OR) time, estimated blood loss (EBL), length of hospital stay (LOS), incision length, Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and the Japanese Orthopedic Association (JOA) score. RESULTS: Five studies were included in this meta-analysis. A total of 770 patients undergoing TLIF were included, with 415 in the CT group and 355 in the TT group. No statistically significant differences were found in the rate of overall complications, including specific complications, the rate of revision surgeries, PROMS scores, OR time, and EBL. However, the CT group demonstrated shorter LOS (p=0.05), and shorter incision lengths (p<.001) compared to the TT group. CONCLUSION: Both TT and CT techniques in TLIF procedures demonstrated comparable rates of complications, reoperations, and PROMs. Despite similar OR times and EBL, the CT group exhibited shorter incision lengths, and shorter LOS compared to the TT group. Both cortical and traditional trajectory pedicle screws are safe and effective options for TLIF. There are potential benefits to CT such as shorter incision and LOS, although TT remains an essential tool for spinal instrumentation techniques.

Laminoplasty Versus Laminectomy and Posterior Fusion for Cervical Myelopathy: A Meta-analysis of Radiographic and Clinical Outcomes.

STUDY DESIGN: Meta-analysis. OBJECTIVE: This meta-analysis investigates the outcomes of laminoplasty (LP) and laminectomy with fusion (LF) to guide effective patient selection for these two procedures. BACKGROUND: While LF traditionally offers the ability for excellent posterior decompression, it may alter cervical spine biomechanics and increase the risk of adjacent segment degeneration. LP aims to preserve the natural kinematics of the spine but has not been universally accepted, and may be associated with inadequate decompression, neck pain, and recurrent stenosis. METHODS: PubMed, Cochrane, and Google Scholar (Pages 1-20) were searched up until March 2024. The outcomes studied were surgery-related outcomes (operating room (OR) time, estimated blood loss (EBL), and length of stay (LOS)), adverse events (overall complications, C5 palsy, and reoperations), radiographic outcomes (cervical lordosis (CL), cervical sagittal vertical axis (cSVA), and T1 slope angle (T1SA)), and patient-reported outcome measures (PROMs) (Neck Disability Index (NDI), Visual Analog Scale (VAS) for neck pain, and Japanese Orthopaedic Association (JOA)). RESULTS: Twenty-two studies were included in this meta-analysis, of which 19 were retrospective studies, two were prospective non-randomized studies, and one was a randomized controlled trial. A total of 2,128 patients were included, with 1,025 undergoing LP and 1,103 undergoing LF. LP patients experienced significantly shorter OR time (P=0.009), less EBL (P=0.02), a lower rate of overall complications (P<0.00001) and C5 palsy (P=0.003), a lower T1SA (P=0.02), and a lower NDI (P=0.0004). No significant difference was observed in the remaining outcomes. CONCLUSION: This meta-analysis demonstrates that for cervical myelopathy, LP has the benefits of shorter OR time, less EBL, and reduced incidence of C5 palsy as well as overall complication rate. Given these findings, LP remains an important surgical option with a favorable complication profile in patients with cervical myelopathy, although careful patient selection is still paramount in choosing the right procedure for individual patients.

Same-Day Versus Staged Spinal Fusion: A Meta-analysis of Clinical Outcomes.

STUDY DESIGN: Meta-analysis. OBJECTIVE: This meta-analysis aims to compare same-day versus staged spine surgery, assessing their effects on patient care and health care system efficiency. BACKGROUND: In spinal surgery, the debate between whether same-day and staged surgeries are better for patients continues, as the decision may impact patient-related outcomes, health care resources, and overall costs. While some surgeons advocate for staged surgeries, citing reduced risks of complications, others proclaim same-day surgeries may minimize costs and length of hospital stays. METHODS: PubMed, Cochrane, and Google Scholar (pages 1-20) were searched up until February 2024. The studied outcomes were operative room (OR) time, estimated blood loss (EBL), length of hospital stay (LOS), overall complications, venous thromboembolism (VTE), death, operations, and nonhome discharge. RESULTS: Sixteen retrospective studies were included in this meta-analysis, representing a total of 2346 patients, of which 644 underwent staged spinal fusion surgeries and 1702 same-day surgeries. No statistically significant difference was observed in EBL between staged and same-day surgery groups. However, the staged group exhibited a statistically significant longer OR time ( P =0.05) and LOS ( P =0.004). A higher rate of overall complications ( P =0.002) and VTE ( P =0.0008) was significantly associated with the staged group. No significant differences were found in the rates of death, reoperations, and nonhome discharge between the 2 groups. CONCLUSIONS: Both staged and same-day spinal fusion surgeries showed comparable rates of death, operations, and nonhome discharges for patients undergoing spinal surgeries. However, given the increased OR time, LOS, and complications associated with staged spinal surgeries, this study supports same-day surgeries when possible to minimize the burden on healthcare resources and enhance efficiency.

ChatGPT Earns American Board Certification in Hand Surgery.

PURPOSE: Artificial Intelligence (AI), and specifically ChatGPT, has shown potential in healthcare, yet its performance in specialized medical examinations such as the Orthopaedic Surgery In-Training Examination and European Board Hand Surgery diploma has been inconsistent. This study aims to evaluate the capability of ChatGPT-4 to pass the American Hand Surgery Certifying Examination. METHODS: ChatGPT-4 was tested on the 2019 American Society for Surgery of the Hand (ASSH) Self-Assessment Exam. All 200 questions available online (https://onlinecme.assh.org) were retrieved. All media-containing questions were flagged and carefully reviewed. Eight media-containing questions were excluded as they either relied purely on videos or could not be rationalized from the presented information. Descriptive statistics were used to summarize the performance (% correct) of ChatGPT-4. The ASSH report was used to compare ChatGPT-4's performance to that of the 322 physicians who completed the 2019 ASSH self-assessment. RESULTS: ChatGPT-4 answered 192 questions with an overall score of 61.98%. Performance on media-containing questions was 55.56%, while on non-media questions it was 65.83%, with no statistical difference in performance based on media inclusion. Despite scoring below the average physician's performance, ChatGPT-4 outperformed in the 'vascular' section with 81.82%. Its performance was lower in the 'bone and joint' (48.54%) and 'neuromuscular' (56.25%) sections. CONCLUSIONS: ChatGPT-4 achieved a good overall score of 61.98%. This AI language model demonstrates significant capability in processing and answering specialized medical examination questions, albeit with room for improvement in areas requiring complex clinical judgment and nuanced interpretation. ChatGPT-4's proficiency is influenced by the structure and language of the examination, with no replacement for the depth of trained medical specialists. This study underscores the supportive role of AI in medical education and clinical decision-making while highlighting the current limitations in nuanced fields such as hand surgery.

Acromioclavicular joint dislocation and concomitant labral lesions: a systematic review.

Acromioclavicular (AC) joint dislocations frequently co-occur with intra-articular glenohumeral pathologies. Few comprehensive studies have focused on labral tears specifically associated with AC joint trauma. This systematic review will address this gap. A comprehensive electronic search was conducted across PubMed, Cochrane Library, and Google Scholar (pages 1-20) spanning from 1976 to May 19, 2023. Seven studies met the inclusion criteria for this systematic review, consisting of three retrospective studies and four case series. These studies collectively involved 1,044 patients, of whom 282 had concomitant labral lesions. The pooled prevalence of intra-articular labral injuries associated with acute AC joint dislocation was 27%. The prevalence of these labral lesions varied significantly between studies, ranging from 13.9% to 84.0% of patients, depending on the study and the grade of AC joint dislocation. Various types of labral tears were reported, with superior labrum anterior to posterior (SLAP) lesions being the most common. The prevalence of SLAP lesions ranged from 7.2% to 77.4%, with higher grades of AC joint dislocations often associated with a higher prevalence of SLAP tears. Moreover, grade V dislocations exhibited a complete correlation with SLAP tears. The studies yielded contradictory findings regarding older age and higher grades of AC joint dislocation as risk factors for concurrent labral lesions. This review underscores the frequent association between labral lesions and AC joint dislocations, particularly in cases of lower-grade injuries. Notably, SLAP lesions emerged as the predominant type of labral tear.

Infantile Fibrosarcoma of the Bone: A Case Report and Literature Review.

Introduction: In adults, fibrosarcoma (FS) of the bone is a rare occurrence. Infantile FS, particularly in the distal radius, is an exceedingly uncommon tumor and, to the best of our knowledge, has not yet been documented in the literature. In the subsequent report, we present a case involving a 2-year-old male diagnosed with primary FS of the distal radius. Case Report: We hereby report the case of a 2-year-old Caucasian boy presenting with primary bone FS in the distal radius. X-rays revealed an osseous mass with an extraosseous component. MRI showed heterogeneous enhancement, suggestive of non-liquefied necrosis or possible fibrosis within the extraosseous soft-tissue component. The patient underwent a resection of the tumor, followed by central translocation of the ulna. Conclusion: Managing infantile FS of the bone requires a multidisciplinary approach. A high index of suspicion is crucial for diagnosing the tumor. Further studies are needed to enhance our approach and management of infantile FS of the bone.

Arthroscopic Meniscus Trephination: A Novel Technique for the Treatment of Symptomatic Meniscal Degeneration: Surgical Technique and Literature Review.

Introduction: Meniscal pathology constitutes a major reason for a vast number of patients suffering from knee pain. It is, in general, attributed either to meniscal tearing or degeneration. Debridement and partial meniscectomy, or repair, when possible, is the mainstay surgical approach for refractory knee pain from meniscal degeneration or tears. Sometimes, the patient has clinical symptoms of meniscal pathology, but despite those highly suggestive clinical symptoms, the patient turns out, during knee arthroscopy, to have meniscal degeneration and hardening of the meniscus without frank tearing of the meniscus. Surgical Technique: To initiate meniscal trephination, we first conduct a diagnostic knee arthroscopy to examine the suprapatellar space, the gutters, and the anterior knee space for any pathologies. Following this, both menisci are inspected for any signs of tearing or hardening. For the purposes of our study, the medial meniscus is considered pathological if it shows signs of degeneration or hardening, which then justifies our intervention. An 18-gauge spinal needle, manually bent for the procedure, is inserted through the portal to perform trephination on the hardened menisci. Care is taken to adequately space the needle insertion points to prevent accidental tearing. Our trephination technique aims to soften the meniscus, facilitating its ability to compact and compress when patients ambulate. Additionally, the needle insertion points help attract blood flow to the meniscus, thereby enriching it with growth factors and stem cells that may aid in improving the degenerative condition. Conclusion: Meniscal trephination is benign and effective for meniscal degenerative pathologies. The procedure allows for a healthier meniscus, free from degeneration, that would otherwise disable patients. The intervention does not have long-term adverse effects. To this end, more comparative trials are required to confirm the effectiveness of the technique and to ensure minimal to no associated side effects.

Low molecular weight heparin in COVID-19: benefits and concerns.

Since its emergence, the COVID-19 pandemic had a dramatic impact on the public health worldwide and it scarred the medical, economical, and social determinants of health. Even after the significant vaccination advances, the disease of SARS-CoV-2 can manifest in severe presentations with life-threatening thromboembolic and multi-organ complications leading to notable morbidity and mortality. Clinicians and researchers are on continuous pursuit of investigating different approaches in the attempt to prevent the infection and minimize its severity. Although the COVID-19's pathophysiology remains relatively unclear, it is well established now that coagulopathy, systemic thrombotic propensity, and a robust immunoinflammatory response are some of the most important determinants of its morbidity and mortality. Accordingly, research efforts have focused on addressing the inflammatory and hematological cascades using available agents to avoid thromboembolic events. Several studies and investigators have emphasized the importance of Low molecular weight heparin (LMWH), namely, Lovenox, in addressing these sequelae of the COVID-19 disease, either prophylactically or therapeutically. This review explores the benefits and concerns of employing LMWH, a widely used anticoagulant, in COVID-19 disease. It delves into Enoxaparin as a molecule, along with its pharmacology, mechanism of action, and clinical uses. It also reviews the current high-quality clinical evidence that highlight the role of enoxaparin in SARS-CoV-2 infection.

COVID-19 in Cyanotic Congenital Heart Disease.

Congenital heart disease (CHD) is the most prevalent congenital defect in newborn infants. Due to the various types of heart abnormalities, CHD can have a wide range of symptoms. Cardiac lesions comprise a range of different types and accordingly varying severities. It is highly helpful to classify CHD into cyanotic and acyanotic heart diseases. In this review, we are investigating the course of Coronavirus disease 2019 (COVID-19) in cyanotic CHD patients. The infection may directly or indirectly affect the heart by affecting the respiratory system and other organs. The effect on the heart that is pressure- or volume-overloaded in the context of CHD is theoretically more severe. Patients with CHD are at a higher risk of mortality from COVID-19 infection or suffering worse complications. While the anatomic complexity of CHD does not seem to predict the severity of infection, patients with worse physiological stages are more susceptible such as cyanosis and pulmonary hypertension. Patients with CHD exhibit continuous hypoxemia and have lower oxygen saturations because of a right-to-left shunt. Such individuals run the danger of rapidly deteriorating in the event of respiratory tract infections with inadequate oxygenation. Additionally, these patients have a higher risk of paradoxical embolism. Hence, critical care should be given to cyanotic heart disease patients with COVID-19 in comparison to acyanotic patients and this is through proper management, close observation, and adequate medical therapy.
