Abstract

Purpose

Proximal row carpectomy and 4-corner arthrodesis are 2 well-established motion-preserving treatment strategies for scapholunate advanced collapse. In this study, we present an arthrodesis technique involving the capitolunate and triquetrohamate joints as another potential treatment option.

Methods

From 2000 to 2009, 27 consecutive patients with degenerative scapholunate advanced collapse and scaphoid nonunion advanced collapse were evaluated prospectively and treated with scaphoid excision and intercarpal arthrodesis between the capitate and lunate and between the hamate and triquetrum. This cohort consisted of 18 men and 9 women, involving dominant-sided surgery in 20 of 27 patients. Two patients were active smokers, and 3 cases were work related. Average age at time of surgery was 55 ± 3 years, and average follow-up was 51 ± 7 months. Preoperative and postoperative range of motion, grip strength, and radiographic evidence of osseous union were documented. Standardized Patient-Rated Wrist Evaluation scores for both pain and function were collected.
