Closed K-wire Fixation for the Treatment of Perilunate Dislocation and Trans-Scaphoid Perilunate Fracture Dislocations without Ligamentous Repair: Short Term Follow-Up

Background: The purpose of this study was to evaluate the treatment outcomes of perilunate dislocations (PLDs) andtransscaphoid perilunate fracture dislocations (TSPLDs) treated with operative volar approach without ligament repairor reconstruction.Methods: A total of seven patients (10 hands) were studied during 2017-2018. We fixed scaphoid fractures thorougha volar approach and 3 k-wires were inserted to stabilize the scaphoid to the adjacent bones. We evaluated patients’range of motion by VAS and grip strength, sensitivity assessment, and radiographs. Mayo and DASH scores were alsorecorded for wrist evaluation.Results: All fractures united well. The mean Mayo wrist score was 81.5. Five patients scored good and excellentresults (90-100). Excellent DASH scores (˂20) were observed in 4 patients and there was no poor DASH score (˃50).Conclusion: Treatment of PLDs and TSPLDs with k-wire and screw fixation using a volar approach and without anyligament repair or reconstruction results in minimal manipulation and has favorable short-term outcomes.Level of evidence: II
