Joint replacement arthroplasty for the treatment of thumb osteoarthritis is gaining popularity as recent studies have demonstrated better pinch and grip strength and faster rehabilitation. Our aim was to identify early complications in modern implant designs using a multicenter study. A total of 381 patients who underwent thumb carpometacarpal replacement surgery in six participating hospitals were enrolled. The complications included were fractures, dislocations, infections, tendon and nerve injuries, and complex regional pain syndrome. Major complications were defined as a failure to implant the prosthesis, revision surgery to remove the implant, and any other need for further surgical intervention. The secondary outcomes were any other complications treated non-surgically and the timing of the complications. Eleven procedures failed, and these patients were treated with trapeziectomies. Twelve other patients required repeat surgical interventions. Minor adverse events occurred in 25.4% of the cases, and transient irritation of the superficial radial nerve and De Quervain tendinopathy were the most prevalent complications. Although this cohort depicted the learning curves of multiple surgeons, our study demonstrated low short-term failure rates. An inability to achieve primary stability of the cup in the trapezium was the leading cause of failure. Dislocations and other major complications with modern implants were very few.

Background/Objectives: Proximal femoral fractures (PFFs) are a common worldwide ailment, causing high morbidity and mortality among the elderly, with one-year mortality estimated at 15–30%. This study aimed to identify factors influencing in-hospital patient survival after proximal femoral fracture surgery. Methods: A retrospective cohort study of patients over 65 admitted to an orthopedic surgery department due to a PFF over five years was carried out. Medical records, surgery reports, anesthesia and post-anesthesia care unit sheets, and laboratory archives were reviewed. Results: The study group consisted of 48 patients who died during the first postoperative week, while the control group consisted of 69 patients who were discharged for rehabilitation after a week. The study group was older, less active, and had higher rates of comorbidities. Anesthetic factors, such as the type of anesthesia and admixture of drugs, did not have a significant association with mortality. However, a binary logistic regression showed that age (OR = 1.15, p < 0.001), intraoperative lactate levels (OR = 5.86, p < 0.001), and post-anesthesia care unit (PACU) overnight stays (OR = 17.54, p < 0.001) were significantly associated with early mortality. Conclusions: The study highlights the challenge of identifying PFF patients at risk of early mortality and the need to better understand the decision-making algorithm to create a reliable scale that can predict mortality and adjust treatment. In our study, solid mortality parameters were age and intraoperative lactate levels. The most significant parameter was PACU overnight stay, which represents the anesthesiologist’s soft-skill-based decision that is challenging to scale and reproduce.

Introduction: Lumbar range of motion (ROM) is a critical component of spinal function and often affected by age and sex. This study aimed to evaluate the variations in lumbar ROM across different age groups in a healthy adult population and determine the influence of sex, height, weight, and body mass index. Methods: A total of 208 subjects (106 men, 102 women) were recruited and stratified into age groups from the 20s to 60s and older. Lumbar ROM was measured using the Wolfson modified Schober test. Data were analyzed for flexion, extension, and total ROM. Linear regression examined the predictors of lumbar ROM. Results: The study found a progressive decline in lumbar flexion and total ROM with age. Age was the only notable predictor of lumbar flexion, with no notable effect of weight and body mass index on ROM. Extension measurements were inconsistent and did not show a clear pattern across age groups. Discussion: Age-related changes in lumbar ROM were consistent with known physiological changes within the spine. Despite physical differences in height and weight, the lumbar spine ROM was similar between sexes, highlighting the influence of age over sex in lumbar motion. Lumbar ROM decreases with age, with flexion affected more than extension.

Introduction: The shoulder rotator cuff (RC) is crucial to shoulder function and involvement in shoulder pathology. RC tears have been extensively studied, and several classifications have been devised to quantify their magnitude. Various RC measurement techniques were introduced previously, utilizing cadaveric specimens, X-rays, CT scans, and MRI with different results published regarding humeral heads’ different plane diameters and the correlation to age, gender, and height. There are very few studies measuring RC length in the general population. Purpose: We aimed to assess the geometrical relation between rotator cuff tendon length and humeral head sagittal and axial diameters. Methods: A total of 100 shoulder MRI scans of labral tear-suspected patients were reviewed, and the geometrical parameters of the rotator cuff length and proximal humerus sagittal and axial diameters were measured. Results: The healthy population has wide variability in humeral diameter and rotator cuff length. We found a high correlation between humeral head sagittal and axial plane diameters and the rotator cuff tendon dimension. The orthogonal plane diameters disagree with the humeral head being round but rather spheric. The rotator cuff length changes according to the patient’s gender and height. Conclusion: This is a novel method for rotator cuff measurement, description, and classification according to the percentage of tear instead of length (cm). This method is more clinically oriented and relevant than most other previous methods.

Background and Objectives: The association between female breast size and spinal back pain is widely suggested in clinical practice but remains insufficiently quantified in general, non-surgical populations in the scientific literature. Larger breasts may increase biomechanical strain on the spine, contributing to musculoskeletal pain and reduced quality of life. This study aimed to evaluate the association between breast size and back pain in a general orthopedic population of young women. Materials and Methods: A cross-sectional study was conducted among 200 women aged 18–36 who attended orthopedic clinics for non-spinal complaints. Data were collected via structured telephone questionnaires, including demographics, self-reported breast size (cup and band), pain characteristics, and SF-12 quality of life scores. Binary logistic regression, ANOVA, and chi-square analyses assessed associations between breast size, pain presence, severity, and functional outcomes. Results: Back pain prevalence increased with breast size: only 4.9% of B cup participants reported backache, compared to 85% of DD/E cup participants. VAS scores rose from 0.3 ± 1.6 (B cup) to 6.0 ± 2.9 (DD/E cup). Each 1 cm increase in band length raised the odds of back pain by 19.8% (OR = 1.198, p < 0.001), while large cup size was associated with up to 12-fold increased odds of pain. Larger breast size was also significantly associated with work limitations and social impairment. Conclusions: Breast size was strongly associated with the presence and severity of back pain, particularly in the thoracic and cervical regions. Clinicians should consider breast size in the assessment of backache, and reduction mammaplasty may have therapeutic value beyond aesthetics.

Introduction: Elbow dislocation is usually treated conservatively with a good outcome. When there is associated injury to the capitellum, “Osborne-Cotterill Lesion,” then the clinical course is less predictable and controversial. In this article, we attempt to define the critical point on the capitellum surface that, when breached, forebodes potential engagement of the radial head in the defect and imminent dislocation. Case Report: We present two cases of fracture and fracture dislocation of the elbow with “Osborne-Cotterill lesion.” They were treated with fracture reduction and fixation. In the first case, a posterior plate was utilized for the olecranon, and in the second case, cannulated screws were employed for the capitellum fracture. In both cases, a posterior humeral plate was applied to counteract the “Osborne-Cotterill lesion” with bone grafting of the defect. Conclusion: When the critical point of the capitellum is breached (roughly a quarter of the capitellar articular surface or less when the radial head is injured),we recommend bone grafting the defect and plating the posterior capitellum to impede potential dislocation.
