Proximal row carpectomy versus four-corner arthrodesis: a retrospective comparative study.

Background: Four-corner arthrodesis with scaphoid excision (FCA) and proximal row carpal resection (PRC) are frequently performed in wrists with post-traumatic Scaphoid Non- Union Advanced Collapse (SNAC)/Scapho-Lunate Advanced Collapse (SLAC) osteoarthritis. The aim of this study was to compare the clinical outcomes of these two procedures.

Methods: This single-center, retrospective cohort study included all patients who had PRC or FCA between January 1st, 2009 and January 1st, 2019 and who were followed up.

Bone-retinaculum-bone reconstruction for chronic posttraumatic instability of the metacarpophalangeal joint of the thumb.

Purpose: This study presents an autograft technique for the surgical management of chronic posttraumatic instability of the thumb metacarpophalangeal (MCP) joint by using a bone-retinaculum-bone graft from the second compartment of the extensor retinaculum.

Methods: The bone-retinaculum-bone graft was harvested from the second compartment. The graft ends were fixed into the host site with screws.
