Summary
Standard wrist arthrodesis implants are generally designed for adult joints with arthritis. They are often too big for patients with limb spasticity who generally tend to have osteopenic and smaller bones for their age, resulting in high complication rates. We previously described the novel use of volar distal radius variable-angle locking plate (APTUS® Wrist distal radius system 2.5, Medartis AG, Basel, Switzerland) on the dorsum for wrist arthrodesis in patients with limb spasticity. This study aimed to further establish the use of the implant by reporting the outcomes in cohort A (nondistal radius plate) and cohort B (distal radius plate cohort). Patient-reported outcome measures were used to assess the primary outcome, whereas secondary outcomes included implant-related complications and improvement in wrist position and fusion rates. A total of 17 wrist arthrodesis procedures were performed over a period of 4 years in 15 patients for wrist deformity secondary to limb spasticity. There were no complaints of implant prominence, implant or tendon irritation, metacarpal prominence, or extension requiring further treatment in cohort B. Cohort A had a high implant removal rate that is comparable to the published literature. Both groups reported significant improvement in hygiene and wrist position but neither group had any appreciable gain in function. Volar distal radius variable-angle locking plates appear to be safe and have superior patient acceptability and low complication rates when used dorsally for wrist arthrodesis in patients with upper limb spasticity. Comparable overall satisfaction rates in cohort B were reported in relation to the literature and the cohort A in this study.
