Abstract
Background
Compared with traditional methods of fixation in four-corner arthrodesis, reviews of results using a dorsal circular plate (DCP) have identified higher complication rates. As the use of circular plate fixation for limited wrist arthrodesis was found to be a valuable concept per se and continued innovation and technical advancement are crucial to improve future treatment, changes in plate design were encouraged.
Questions/purposes
To further evaluate the use of DCP fixation in four-corner arthrodesis, we report the first results using a radiolucent, nonmetallic (polyetheretherketone), locked DCP for four-corner arthrodesis.
Methods
We retrospectively analyzed the clinical and radiographic results of 24 patients who underwent four-corner arthrodesis with a locked DCP at a minimum followup of 63 months (mean, 76 months; range, 63–91 months). There were nine women and 15 men, with a mean age of 53 years (range, 37–78 years) at the time of surgery. We evaluated ROM with a goniometer and grip strength with a dynamometer. Function was assessed using QuickDASH. Radiographs were evaluated for union, carpal alignment, and hardware problems.
Results
At latest followup, ROM averaged 66% and 77% of the uninjured side in flexion-extension and radioulnar deviation, respectively. Grip strength averaged 70% of the uninjured side. The average postoperative QuickDASH score was 19.11. Union was achieved by 22 of the 24 patients.
Conclusions
Our data show four-corner arthrodesis with a radiolucent, nonmetallic, locked DCP is an effective procedure that allows stable primary fixation as a basis for good functional outcome, provided surgical technique and quality of bone graft are adequate.
