Summary: This study evaluates the thickness and density of subchondral bone in the trapeziometacarpal joint and their relationship with early-stage osteoarthritis. The results show that lower thickness and higher density are associated with decreased bone mineral density, elevated osteocalcin levels, and more severe osteoarthritis.

Summary: This article focuses on the anatomy and biomechanics of the trapeziometacarpal joint, as well as the best evidence for diagnosis and treatment of thumb osteoarthritis. It also touches on treatment pitfalls and complications avoidance when dealing with this type of arthritis.

Summary: This study compared the outcomes of two surgical procedures for thumb carpometacarpal (TCMC) osteoarthritis and found that the double-mobility TCMC prosthesis had superior outcomes at 6 weeks, but no significant differences at 6 months and 1 year postoperatively. The implant survival rate after 12 months was 96%, which was acceptable.

Summary: The purpose of this study was to evaluate changes in the range of motion (ROM) of the thumb MCP joint before and after TMC arthrodesis. The results showed that the motion of the MCP joint shifted from hyperextension to flexion after TMC arthrodesis, but there was no significant change in the total ROM.

Summary: Painful habitual instability of the thumb basal joint (PHIT) is a rarely diagnosed condition that can severely impair hand function and increase the risk of developing carpometacarpal arthritis of the thumb (CMAOT). This study investigated two radiographically obtainable parameters, slope angle and bony offset, as potential risk factors for PHIT. The results showed a significant association between high bony offset values and PHIT.

Summary: Injuries to the ulnar collateral ligament (UCL) of the thumb metacarpophalangeal joint, also known as gamekeeper's thumb, are common and can cause pain and instability. Diagnosis can be made through physical examination or imaging techniques. Surgical treatment options, including suture tape augmentation, have excellent outcomes and low complication rates.

Summary: The basal joint complex of the thumb is crucial for hand function but can be unstable and painful due to various reasons, requiring thorough evaluation and treatment options.

Summary: This study aimed to improve existing models by creating a muscle-driven finite element thumb model and using it to simulate the biomechanical effects of hand therapy exercises and ligament reconstructive surgeries. The results showed that tightening the dorsal ligament complex, thenar eminence strengthening, and Eaton-Littler reconstruction were the most effective interventions in reducing cartilage stress. These findings align with clinically observed favorable outcomes.

Summary: Over the past 19 years, the number of patients undergoing BTOA surgery has increased, with a low rate of further procedures and SAES after surgery. Patients undergoing arthrodesis and arthroplasty were significantly more likely to require a further procedure than those undergoing simple trapeziectomy.

Summary: This study investigated the changes in anterior knee laxity, stiffness, general joint laxity, and genu recurvatum during the menstrual cycle in female non-athletes and athletes. Results showed that stiffness was significantly higher in the oligomenorrhea group compared to the eumenorrhea group, and genu recurvatum was significantly higher in the late follicular, ovulation, and luteal phases compared to the early follicular phase in female athletes.

Summary: This study aimed to examine the effect of thumb interphalangeal joint position on movements of the trapeziometacarpal joint during thumb opposition. The findings suggest that thumb interphalangeal joint extension increases trapeziometacarpal joint movement and thenar muscle activity, indicating the importance of thumb interphalangeal joint position in thumb opposition.

Summary: This study quantified and analyzed the 3D kinematics of RS, ST, and TMC joints during thumb movement in a healthy population. Strong inter-joint coupling was observed between RS and ST joints, while coupling between other joints was moderate to weak. These findings provide valuable input for modeling studies and can be compared to patients with TMC osteoarthritis or other joint pathologies.

Summary: Trapeziometacarpal joint arthrodesis decreases the range of thumb circumduction motion, but subsequent resections at the trapeziotrapezoid and trapezio-second metacarpal joint spaces can increase thumb motion range.

Summary: By investigating the anatomical relationships, we have determined the pathogenesis of TMC joint instability and found that the dorsal ligaments are part of the capsuloaponeurotic complex consisting of the FDI aponeurosis and joint capsule. Additionally, we have found that the activation of OPP muscle is essential for TMC joint stabilization.
