Background: The purpose of this study was to evaluate the treatment outcomes of perilunate dislocations (PLDs) and
transscaphoid perilunate fracture dislocations (TSPLDs) treated with operative volar approach without ligament repair
or reconstruction.
Methods: A total of seven patients (10 hands) were studied during 2017-2018. We fixed scaphoid fractures thorough
a 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 also
recorded for wrist evaluation.
Results: All fractures united well. The mean Mayo wrist score was 81.5. Five patients scored good and excellent
results (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 any
ligament repair or reconstruction results in minimal manipulation and has favorable short-term outcomes.
Level of evidence: II
