Ulnar abutment (ulnocarpal impaction) syndrome may be a source of ulnar-sided wrist pain in the athlete. This condition results from excessive load transfer across the triangular fibrocartilage complex and ulnocarpal joints with characteristic degenerative changes. It frequently occurs in patients with either static or dynamic ulnar positive variance. Treatment is tailored to the athlete and their sporting demands. Surgical treatment focuses on addressing ulnar variance to unload the ulnocarpal joint, with multiple surgical options, including the metaphyseal closing wedge osteotomy achieving this goal. This review focuses on the presentation, biomechanics, and treatment options for ulnar abutment syndrome in the athlete.

We present the case of a 47-year-old patient with a congenital positive ulnar variance and elucidate its effects on nearby structures in relation to ulnocarpal abutment syndrome (UAS). While magnetic resonance imaging (MRI) helped to identify soft tissue changes in the wrist, the use of an arthrogram, in this case, allowed for a more comprehensive and detailed analysis of the ligaments and soft tissues. Image findings included a complex degenerative tear of the disc of the triangular fibrocartilage (TFCC), a degenerated triquetrum, and partial tears of the scapholunate and lunotriquetral ligaments.

Objectives: The primary purpose of this study was to compare the rates of nonunion among different osteotomy designs (company brand) and the rates of nonunion between oblique and transverse osteotomies. We secondarily aimed to assess the differences in reoperation and hardware removal rates after ulnar shortening osteotomy (USO).
Methods: A retrospective cohort study of patients undergoing ulnar shortening osteotomy between 2015 and 2022 in our institute amongst 17 providers resulted in 92 consecutive patients.

Context: Ulnar variance (UV) is a measurement of the relative locations of the radius and ulna that may become perturbed in athletic populations. Positive UV can be associated with wrist pathologies often treated conservatively or surgically and may result in interruption of sports participation.
Objective: This scoping review aims to summarize diagnostic measures of UV in athletes, describe its relation to separate wrist conditions, and present treatment strategies for symptomatic UV.

Open or arthroscopic partial resection of the elongated ulnar styloid is the surgical treatment of choice for ulnar styloid impaction syndrome. A patient with a severely elongated processus styloideus ulnae (PSU) with a chronic impaction of the distal-radial margin against the triquetrum suffered a traumatic triangular fibrocartilage complex (TFCC) Palmer 1B rupture and DRUJ instability. The length of the PSU was 9 mm.

Ulnocarpal impaction syndrome is a common cause for ulnarsided wrist pain caused by an abutment between the ulnar head and the lunotriquetral complex. This pain is typically triggered by load bearing and rotation of the forearm. Radiographic examination is often associated with positive ulnar variance and cysts in the lunate, edema of the ulnoproximal lunate is shown in MRI.
