[Palmar radioscapholunate arthrodesis with distal scaphoidectomy]. Oper Orthop Traumatol. 2020 Feb 25;: Authors: Quadlbauer S, Leixnering M, Rosenauer R, Jurkowitsch J, Hausner T, Pezzei C Abstract OBJECTIVE: Radioscapholunate (RSL) arthrodesis with distal scaphoidectomy using an angular stable plate and palmar access in post-traumatic or degenerative osteoarthritis limited to the radiocarpal joint. INDICATIONS: Osteoarthritis limited to the radiocarpal joint with intact mediocarpal joint after malunited intra-articular distal radius fractures, rheumatoid osteoarthritis, scapholunate advanced collapse (SLAC) up to stage II. CONTRAINDICATIONS: Mediocarpal osteoarthritis, poor patient compliance, SLAC from stage III, osteitis. SURGICAL TECHNIQUE: The palmar RSL arthrodesis is performed using the palmar approach between the flexor carpi radialis tendon and the radial artery. After releasing the pronator quadratus muscle, a longitudinal capsulotomy is performed and the radiocarpal joint is inspected. After correction of a volar or dorsal intercalated segmental instability of the lunate, the lunate is temporarily fixed to the scaphoid using a K-wire. The distal quarter of the scaphoid and the palmar rim of the distal radius is resected and the cartilage between the scaphoid, lunate and distal radius is removed. The scaphoid and lunate are temporarily fixed to the distal radius using K‑wires. Under image inte...
