[Indexed for MEDLINE] 15. Hand Clin. 2005 Nov;21(4):553-9. doi: 10.1016/j.hcl.2005.08.006. Proximal row carpectomy. Diao E(1), Andrews A, Beall M. Author information: (1)Department of Orthopaedic Surgery, University of California San Francisco, 500 Parnassus Avenue, MU320W, San Francisco, CA 94143-0728, USA. diaoe@orthosurg.ucsf.edu Proximal row carpectomy is extremely useful as a wrist reconstructive technique for cases of degenerative joint arthritis of the radiocarpal joint cause by scapholunate advanced collapse, scapholunate advanced collapse, schaphoid nonunion advanced collapse, trans-scaphoid perilunate fracture dislocations, lunate dislocations, and Kienböck disease. It should be selected with caution for patients younger than 35 years old. The procedure can be performed with or without temporary internal fixation with with Kirschner wires, and adjunctive techniques of dorsal capsule interposition, proximal capitate excision, and radial styloidectomy can be used. The longevity of the operation is good, but the patient should be informed preoperatively that secondary procedures may be required. Based on historical series, these procedures have included addition have included of radial styloidectomy when this has not been performed at the index procedure, revision of the surgery with capitate debridement or conversion to total wrist arthodesis. Conversion of proximal row carpectomy to total wrist arthoplasty with implants can be contemplated in selected patient particularly as newer implants are designed. The technique the senior author has used on occasion has been to perform revision surgery on those patients who have chronic pain who might need further debridement of the radius in the radial styloid, the proximal capitate, or evaluation of the integrity of the interposition.
