A new plate for partial wrist fusions: results in midcarpal arthrodesis.

Partial wrist fusions are commonly performed for various degenerative conditions. In this series 30 wrists had a scaphoidectomy and midcarpal arthrodesis performed with a new plate. The most common indications were SLAC and SNAC wrists. In 24 cases a four-corner arthrodesis was done and in the other six the triquetrum was not included. Mean follow-up was 3 years. Mean flexion was 31° and extension 35°. Union was achieved in all wrists despite movement being commenced early. The plates proved straightforward to use, allowing some latitude in placement. This series confirms that scaphoidectomy and midcarpal arthrodesis is a useful salvage procedure and that these plates are suitable for that purpose.
