Unstable distal clavicle fractures: Outcomes of internal fixation of clavicle and coracoclavicular stabilization

Puntos clave

This research aims to evaluate the outcomes of internal fixation techniques for unstable distal clavicle fractures, especially with or without coracoclavicular stabilization.
Retrospective review of patients from 2017 to 2024 who underwent open repair of unstable distal clavicle fractures.
Fixation techniques included locking plate alone or with coracoclavicular stabilization methods.
Outcome measures included PROMIS scores, ASES scores, and VAS pain scores.
Seventeen patients were followed for an average of 32.0 months, with PROMIS scores indicating moderate function (49.2).
Three patients (18%) experienced postoperative complications like plate prominence and shoulder stiffness, with no reoperations required.
Adding coracoclavicular stabilization resulted in favorable outcomes and predictable healing rates.

Resumen

Background This study evaluates outcomes following internal fixation of unstable distal clavicle fractures (DCFs) with or without coracoclavicular (CC) stabilization. Methods A retrospective review was conducted for patients who underwent open repair of unstable DCFs at a single institution from 2017 to 2024. Fixation techniques included locking plate alone (P) or plate with CC stabilization transcoracoid suture button (P + B), coracoid anchor (P + A). Collected variables included demographics, clinical details, patient-reported outcome measurement information system (PROMIS) scores, American Shoulder and Elbow Surgeons (ASES) scores, and Visual Analog Scale (VAS) Pain. Results Seventeen patients with DCFs (17 shoulders;11 males, 6 females; mean age 45 23–78 years) were followed for an average of 32.0 (3.4–69.3) months. Fixation groups included P (6), P + B (8), and P + A (3). Neer types included IIA (4), IIB (6), and V (7). Mean outcome scores were PROMIS upper extremity 49.2 ± 10.5, pain interference 47.0 ± 7.2, pain intensity 39.3 ± 7.0, ASES 89.3 ± 14.3, and VAS 1.5 ± 2.2. Three patients (18%) experienced postoperative issues: plate prominence (2) and shoulder stiffness (1); none required reoperation. Discussion The addition of CC stabilization to locking plate fixation in high-risk unstable DCFs results in favorable outcomes and predictable healing rates. Level of evidence IV, case series.
