Abstract	INTRODUCTION: Peri-lunate wrist dislocations and fracture-dislocations are related to high-energy trauma. Prognosis is often compromised because of the complexity of the lesions. The purpose of this study was to assess outcomes of acute peri-lunate injuries and correlate them with the type of lesion and management. MATERIEL AND METHODS: A monocenter retrospective study has been conducted. Sixty-five patients (65 wrists) were reviewed. According to Herzberg's classification, there were 18 isolated peri-lunate dislocations and 47 peri-lunate fracture-dislocations - 27 with a scaphoid fracture and 20 with an intact scaphoid. The displacement was dorsal in 62 cases. All patients were treated surgically. RESULTS: At an average follow-up of 8 years (2-16) the average Cooney score was 66 points, quick-DASH score 21 points, and PRWE score 28 points. Pain score was 1.3 out of 10 points at rest and 4.3 out of 10 with effort. The flexion-extension arc was 96° with an average strength of 38kg (70±23% of opposite side). Radiographic analysis has shown decrease in carpal height, increase in ulnar translation, and DISI. Sign of wrist arthritis was found in 58.5% of the cases. The rate of osteonecrosis was 7.7%. Regional sympathetic painful syndrome was observed in 12%. In 26% of the cases a secondary surgery was needed. No influence has been found with the final results between fracture-dislocation and isolated dislocation, and delay of treatment. Osteochondral lesions observed at surgery (P=0.035), osteonecrosis at follow-up (P=0.017), and modification of the scapho-lunate angle (P=0.029) were correlated with the occurrence of osteoarthritis. DISCUSSION: Peri-lunate dislocation and fracture-dislocation represent severe wrist trauma with often numerous sequelae with follow-up: pain, stiffness, loss of strength, carpal instability and arthritis. Early diagnosis and anatomic reduction are prerequisite to a satisfactory functional result. Capsulo-ligamentous lesions must be repaired and fractures must be fixed. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
