Lunotriquetral arthrodesis using cancellous bone graft.

Previous reports of lunotriquetral arthrodesis suggest relatively low rates of primary fusion without the use of permanent fixation and/or prolonged immobilization. We performed 26 lunotriquetral arthrodeses in 24 patients with a technique using cancellous bone graft to fill a biconcave space created in the adjoining bones with parallel K-wire fixation. The indications included symptomatic lunotriquetral instability and degenerative arthritis. All patients received conservative treatment before surgery. Primary fusion was achieved in all wrists in an average of 50 days. Postoperative wrist flexion/extension averaged 77%/80% of unaffected sides. Radial/ulnar deviation averaged 95%/91% of unaffected sides. Pain relief was good or very good in 83%. Eight-eight percent returned to the workforce. This study shows reliable, effective results with a technique that adheres to the principles of intercarpal arthrodesis and avoids permanent internal fixation.

One thousand intercarpal arthrodeses.

Limited wrist arthrodesis is a useful method for treating specific carpal disorders that maximizes residual wrist motion and strength while eliminating pain. Selective fusion of specific carpal units can be used in degenerative arthritis, rotary subluxation of the scaphoid, midcarpal instability, scaphoid nonunion, Kienbock's disease, and congenital synchondrosis or partial fusion of specific carpal joints. This report presents our experience with more than 1000 limited wrist arthrodeses, and provides a review of the indications and technical considerations for specific intercarpal fusions, and subsequent results. To date this is the largest series of intercarpal arthrodeses and the study has demonstrated that these techniques are reliable and effective in dealing with a wide range of wrist disorders.

The natural progression of scaphoid instability.

Wrist injury or repeated wrist sprains probably result in injury to the scapholunate ligament more commonly than previously recognized, which may allow abnormal scaphoid skid under load. This results in a common clinical entity termed DWS. Scaphoid instability is a spectrum condition ranging from minor, asymptomatic findings (seen in 20% of normal adults) through symptomatic findings in patients with normal radiographs to abnormal instability on radiographs, to degenerative change, and, ultimately, to SLAC wrist (see Fig. 1). Appropriate diagnosis and management of each of these wrist disorders are highly dependent upon a keen understanding of normal periscaphoid anatomy as well as the anatomic derangements that occur within the wrist that predispose a given patient to subsequent degenerative changes. With that understanding, the appropriateness of conservative therapy, SL exploration and arthroplasty, ligament repair, triscaphe arthrodesis, or SLAC reconstruction can be readily determined in each case.
