Unusual Mechanism of Injury during a Wedding Tradition Leading to a Metacarpal Shaft Fracture - A Case Report.

Introduction: "Joota Chori" is a traditional Indian wedding ritual which involves playful competition between the bride's and the groom's friends, with the aim of hiding and retrieving the groom's shoes. Case Report: We describe a rare case scenario wherein an orthopedic surgeon sustained a metacarpal shaft fracture while gripping the shoe and engaging in a tussle with the groom's friends. Despite feeling a sudden snap and experiencing pain, the surgeon held onto the shoe. The subsequent diagnosis revealed a 4th metacarpal long oblique shaft fracture. Conclusion: This case highlights the uncommon mechanism of injury involving forceful hyperextension of the MCP joint and the potential risks associated with physically intense wedding rituals. It also emphasizes the importance of adequate first aid resources and medical attention at wedding venues to promptly address musculoskeletal injuries.

Preoperative estimation of humerus intramedullary nail length using clinical landmarks.

PURPOSE: Intramedullary interlocking nailing is one of the accepted methods of treating humerus diaphyseal fractures. Appropriate nail length and diameter are of paramount importance to achieve a stable fracture fixation. Estimating the nail length can be as challenging in certain cases as it is important. This study aims to provide an easy-to-use formula utilizing clinical measurements from contra lateral arm to accurately estimate humeral nail length. METHODS: This descriptive cross-sectional study was conducted at 3 tertiary care hospitals in Mangalore, India. Patients above the age of 18 years coming to the outpatient department with elbow, shoulder or arm complaints requiring radiological investigation from July 2021 to July 2022 were included. Patients with fractures or dislocations of upper limbs, malunited or non-united fractures of upper limbs, congenital or developmental deformities and patients with open growth plates were excluded. Patients' variables (like age and gender), radiological humerus length and contralateral arm clinical measurements were recorded. An independent samples t-test was used for univariate analysis, and linear regression analysis was done to estimate the desired nail length using the clinical measurement of the humerus (cm) in both genders separately. The significance level was set at p < 0.05. RESULTS: Our study included 204 participants of which 108 were male and 96 were female. The formula for predicting humeral nail length in males is (-2.029) + (0.883 × clinical measurement). The formula for females is 1.862 + (0.741 × clinical measurement). A simplified formula to determine humeral nail length is 0.9 clinical length - 2 cm (in males) and 0.7 × clinical length + 2 cm (in females). CONCLUSION: To improve the stability of fixation with intramedullary nails it is imperative to select the appropriate nail length. There have been studies that devised reliable methods of determining nail lengths in the tibia and femur using preoperative clinical measurements. A similar clinical method of determining humeral nail length is lacking in the literature. Our study was able to correlate radiological lengths of the humerus medullary canal with clinical measurements performed using anatomical landmarks to arrive at a formula. This allows for a reliable and easy nail length determination preoperatively.

Cardiovascular Outcomes of Redo-coronary Artery Bypass Graft Versus Percutaneous Coronary Intervention of Index Bypass Grafts Among Acute Coronary Syndrome: Regression Matched National Cohort Study.

Procedural and hospital outcomes of Percutaneous coronary intervention (PCI) versus Coronary artery bypass grafting (CABG) among ACS patients with prior history of CABG remains understudied. PCI and CABG formed the 2 comparison cohorts. Nationwide Inpatient Sample (NIS) from 2015 to 2020 were analyzed using the ICD-10 coding system. Demographic characteristics, baseline comorbidities, and outcomes such as inpatient mortality, cardiogenic shock, mechanical circulatory support, length of stay (LOS), and cost of hospitalization were compared between the two cohorts. A total of 503,900 ACS hospitalizations with prior history of CABG were identified who underwent PCI and CABG (141650 vs 7715, respectively). Median age was 71 vs 67, with male predominance (74.6% vs 75.4%), Caucasian had the most hospitalizations (79.3% vs 75.1%) in the PCI group compared to patients who underwent CABG. A higher burden of smoking (57.1% vs 52.6%, P < 0.0001) was noted in the CABG group. On adjusted analysis, ACS patients undergoing Redo- CABG had a higher risk of in-hospital mortality (aOR 1.69, CI 1.53-1.87, P < 0.0001) compared to those undergoing PCI. In addition, Redo-CABG group were more likely to have CS (aOR 1.37, CI 1.26-1.48, P < 0.0001), MCS devices use (aOR 2.61, CI 2.43-2.80, P < 0.0001), AKI (aOR 1.42, CI 1.34-1.50, P < 0.0001) and respiratory failure (aOR 1.39, CI 1.29-1.47, P < 0.0001) as compared to PCI group. CABG in acute myocardial infarction with prior history of CABG is associated with higher cardiovascular complications compared to PCI. Further exploration and individual-patient level risk assessment is crucial.

"Screw First" Technique to Get Past Nail-Jig Mismatch in Proximal Femoral Nailing.

Proximal femoral nailing is the gold standard of surgical treatment for unstable intertrochanteric hip fractures. One of the intraoperative complications encountered in this procedure is the nail-jig mismatch due to causes such as manufacturing errors and fatigue deformation of sleeves or jig. Nail-jig mismatch leads to eccentric placement of guidewire within the screw slots of PFN and subsequent difficulty in reaming and screw insertion. The potential complications of this include guide wire deformation, breakage, nail damage and screw malposition. We propose a simple and effective technique to tackle this complication, called as "Screw first" technique. The principle of this technique is to utilize screws as guide wire sleeves to effectively centralize the guidewire position within nail slots. On identifying a mismatch by the eccentric position of guidewire, a long screw is first inserted partially till its shaft engages into the screw slot allowing subsequent insertion of a guidewire which assumes a centralized position, thus bypassing the mismatch of jig. Following this, the usual steps of reaming and final screw insertion are undertaken. This method is effective, simple, quick and requires no special instrumentation.

Neurogenic heterotopic ossificans of hips in a case of expanded dengue syndrome following critical illness polyneuropathy.

We present a case of 71-year-old man with bilateral hip neurogenic heterotopic ossificans following critical illness polyneuropathy as a complication of expanded dengue syndrome. His left hip was stiff and showed a circumferential ossific mass. After initial medical management, the patient underwent excision of ossific mass using posterior approach. For adequate excision, femoral head and neck were resected and a hybrid total hip arthroplasty was performed. The patient was followed up for 2 years and showed good clinical outcome without recurrence of heterotopic ossification. This case highlights the rare aetiology of neurogenic heterotopic ossification which is critical illness polyneuropathy following expanded dengue syndrome. It highlights that adequate resection and a total hip arthroplasty can be a viable option in selected cases of circumferential heterotopic ossification in old individuals.

Cross-sectional assessment of cardiovascular risk factors in patients with knee osteoarthritis.

Background: Osteoarthritis (OA) and cardiovascular disease (CVD) are prevalent in India. However, there is dearth of literature among Indians studying the relationship between the two. This study was carried out to assess various cardiovascular (CV) risk factors in patients with knee OA with an objective to investigate their association, screening and management.  Methods: In total, 225 patients were included in this cross-sectional study. Participants were diagnosed with knee OA on the basis of the Kellgren and Lawrence (K-L) classification of their radiograph. Participants were also assessed for CV risk factors; age, body mass index, systolic blood pressure, diabetes mellitus, total cholesterol, high-density lipoprotein, smoking. Joint British Society QRisk3 calculator (JBS3) a comprehensive risk score calculator as well as a screening tool, which produces three more variables, namely 10-years risk of developing CVD, physiological heart age and life expectancy, was used. Chi Square, Fishers exact test and one-way ANOVA tests were used to compare the categorical and quantitative variables, respectively.. Multiple regression analysis was done to adjust the multiple con-founders and determine their significance. Results: Patients with severe knee OA had a statistically significantly higher prevalence of CV risk factors (p<0.05). Grade 4 knee OA patients were found to have a mean JBS3 risk of 38%, heart age of 82 years and life expectancy of 77 years as compared to grade 2 patients who had a mean JBS3 risk of 11%, heart age of 63 years and life expectancy of 82 years.  Conclusions: Our study concluded that there is a strong relation between knee OA and CVD, with CV risk score being positively correlated to the severity of OA.
