Abstract:
We report two cases of extensor pollicis longus tendon tethering following K-wire insertion to treat unstable distal radius fractures, an unusual complication. In both cases, extensor pollicis longus function returned with conservative management. The structures considered "at risk" during K-wire insertion are described, and the common complications are discussed. Operative approaches to minimise soft tissue damage during K-wire insertion are reviewed. This case report is the first to demonstrate the potential for ultrasound scanning to aid in the diagnosis of extensor pollicis longus tethering.
