Mid- to Long-Term Clinical and Radiological Outcome after Perilunate Injuries

Abstract Background Perilunate dislocations (PLD) and perilunate fracture (PLFD) are rare but severe injuries to the wrist, usually resulting from a high-energy trauma occurring in sports injuries, motor vehicle accidents, falls or machine related accidents. Treatment of choice is early reduction with carpal transfixation, fixation refixation injured ligaments. Aims As reports on mid- long-term outcome scarce, we aimed investigate clinical radiological open treatment after minimal follow-up 2 years. Methods Patients treated for PLD PLFD our institution were identified back 2008. Inclusion criteria who underwent surgery, had years available follow-up. Clinical examination included ROM grip strength. PRWE, quick DASH, SF-12 single assessment numeric evaluation (SANE) score used as PROMs. Dorso-palmar lateral X-rays done assessed height, inter- radio-carpal angles degenerative changes. Results Of 54 patients, 29 patients could be located contacted. By date abstract submission 15 9 been followed-up clinic. Mean was 93 months (24-170). F/E 43/0/51° affected 68/0/66° healthy P/S 77/0/73° 79/0/79°, R/U 24/0/34° 27/0/44°. strength 41kp 61kp. PRWE 13.2, qDASH 14.2%, physical 50.9, mental 55.1 SANE 86%. 11 showed slight moderate Carpal height (Nattrass Index) mean 1.45. Conclusions Although wrists reduced scores, mostly satisfied only exhibited little pain. Open reliably lead satisfactory results even long-term.
