The purpose of the study was to examine the possibilities of high resolution US to visualize and diagnose the changes within the fissures of hand metacarpophalangeal joints and to assess the dimensions of metacarpophalangeal joints in healthy people and selected diseases. The study involved 44 individuals subjected to ultrasound examinations of the hands. The group included 35 healthy right-handed persons (22 women and 13 men), aged 21-53 (average - 33), 7 right-handed patients with rheumatoid arthritis (RA) (5 women and 2 men), aged 41-73 (average - 54) and 2 right-handed men treated for acromegaly, aged 43 and 58. The Logic 500 ultrasonograph (GE) was used. The images of metacarpophalangeal joints of both hands in the dorsal transverse and longitudinal projections were performed using the broad-band linear head with the frequency of 8.5-11 MHz. The analysis included 880 measurements of the metacarpophalangeal joints. The results were presented using the metacarpophalangeal joints of the 1st and 3rd fingers. The results in men and women, healthy and ill individuals were compared. In the authors' opinion high resolution US is a valuable method of imaging the anatomical structures of metacarpophalangeal joints, which may be used to evaluate morphological changes and to estimate the degree of joint destruction in some diseases.

A 42-year-old man suffered an avulsion amputation of his right middle finger. He had undergone several surgeries since the age of 24, including amputation plasty and implantation of the injured nerve into fat and bone, but had difficulty returning to work due to persistent severe pain. He underwent nerve capping with an artificial nerve conduit at a university hospital, and his symptoms improved slightly, but immediately flared up again.

Intra-articular corticosteroids, such as triamcinolone acetonide (TA), help reduce pain related to osteoarthritis (OA), but they may impair cartilage metabolism. In contrast, platelet-rich plasma (PRP) therapy, a regenerative therapy, has shown potential to promote healing and regeneration of articular cartilage. This study investigates the effects of combining PRP with TA to treat osteoarthritis in racehorses.

Background: Extra-articular but severely comminuted distal basal fractures of the proximal phalanx (PP) are rarely reported. Therefore, the aim of this study was to achieve proper union and desirable outcomes using low-profile locking plates/screws. We introduced our own surgical approach and reported the clinical/radiographic outcomes via retrospective case series.

Article Synopsis
- Non-Dupuytren's contracture, often resulting from trauma or surgery, usually doesn't need surgery; however, in this case, an 81-year-old woman had a series of surgeries for finger issues, leading to ongoing complications.
- During her surgeries, procedures like limited fasciectomy, flexor tenolysis, and joint mobilization were performed, but the flexion contracture persisted after initial attempts.
- Ultimately, despite multiple interventions including excision of the cord and attempts to improve motion, the flexion contracture recurred, highlighting the need to anticipate potential recurrence in surgical planning for non-Dupuytren's contracture.

Background: Adhesion formation poses a significant challenge for both patients and hand surgeons following tendon repair. One common strategy to prevent adhesion formation is the use of physical barriers. This study aimed to compare the outcomes of extensor tendon repair with and without the application of the OrthoWrap bioresorbable Sheet, specifically in terms of adhesion prevention.
