Abstract：Objective To summarize and analyze the clinical outcomes of arthroplasty for traumatic arthritis of the 5th carpometacarpal ( CMC ) joint. Methods From January 2006 to January 2011, 6 patients were identiifed with traumatic arthritis of the 5th CMC joint. There were 5 males and 1 female, with a mean age of ( 45±10 ) years old ( range;31-55 years ). One case was on the left side, and the other 5 cases were on the right side. All patients underwent Scheker CMC arthroplasty. The clinical and radiographic outcomes were respectively recorded preoperatively and postoperatively, including the grip strength, the 5th metacarpophalangeal ( MCP ) range of motion ( ROM ) and the 5th metacarpal height. The Visual Analogue Scale ( VAS ) was used to assess the subjective degree of pain before and after the operation. Results All patients were followed up for an average period of ( 17.6±10.4 ) months ( range;9-36 months ). The osteotomy union were obtained after an average period of ( 6.2±0.8 ) weeks ( range;5-7 weeks ) after the CMC arthroplasty. The grip strength was improved from ( 33.6±12.2 ) kg before the operation to ( 44.2± 12.7 ) kg after the operation, and the differences were statistically signiifcant ( t=-4.566, P=0.006 ). The ROM of the 5th MCP joint of the affected little ifnger was ( 88.5±3.6 ) ° before the operation and ( 87.8±2.6 ) ° after the operation, and the differences were not statistically significant ( t=1.195, P=0.286 ). The 5th metacarpal height was ( 53.7± 4.0 ) mm before the operation and ( 52.3±3.6 ) mm after the operation, and the differences were not statistically significant ( t=1.754, P=0.140 ). The VAS scores were improved from 2.8 points preoperatively to 0.2 points postoperatively on average. Conclusions Scheker CMC arthroplasty is an effective method for traumatic arthritis of the 5th CMC joint, with the grip strength improved and the pain of the ulnar-sided wrist relieved.
