Background The aims of this study were to evaluate the associated injuries occurring with acute perilunate instability and assess clinical radiographic outcomes dislocations fracture–dislocations treated a combined dorsal volar approach. Methods A total 45 patients (46 wrist injuries) prospectively evaluated. size mid-carpal ligament tear, location scapholunate presence osteochondral fragments radio-carpal avulsions recorded at injury. Final evaluated in 25 cases (25 wrists) minimum 6 months follow-up. Results Intraoperative examination 46 operative treatment showed carpal tear be present 100 % time an average length 3.4 cm. Complete avulsion extrinsic ligaments was found 65.2 cases. torn 35 Osteochondral either volarly or dorsally 74 flexion–extension arc 82°, forearm rotation 155°, grip strength averaged 59 uninjured hand. final angle 55° gap 2.2 mm. Conclusion Treatment approach results reasonable functional results. incidence these is high. Although have slightly better radiologic alignment than dislocation group, outcome similar.
