Four-corner fusion: Clinical and radiological outcome after fixation by headless compression screws or dorsal locking plate at minimum 5 years’ follow-up - 24/08/21
Abstract |
Introduction |
Among the various procedures for degenerative carpal lesions, four-corner fusion relieves pain while conserving motion and strength. There are various fixation options, not presently standardised.
Hypothesis |
Internal fixation by screws or dorsal locking plate provides good 5-year clinical results in four-corner fusion.
Material and method |
A single-centre retrospective study included 18 four-corner fusions at a minimum 5 years’ follow-up: 8 plate and 10 screw fixations. Endpoints comprised pain, wrist range of motion, grip strength, QuickDASH and PRWE scores, and immobilisation time. Radiographic analysis was performed and complications inventoried.
Results |
Pain VAS score fell to 1/10 in both groups. Flexion–extension was 56° with screws and 55° with plates. QuickDASH was 20.5 and 4.6 respectively, and PRWE 11 and 9. Grip strength was 16kg in both groups. The consolidation rate was 85.7% with screws and 57.1% with plates. Eighty percent of patients with screw fixation progressed toward radiolunate osteoarthritis. Four patients required revision surgery: 3 in the screw group and 1 in the plate group.
Discussion |
There was clear clinical and functional improvement in both groups at a minimum 5 years. Consolidation was better with screw fixation, but with risk of radiolunate osteoarthritis.
Level of evidence |
IV, retrospective study.
