ABSTRACT: Introduction: Traumatic hip dislocation, defined as the complete and permanent displacement of the femoral head from the acetabular cavity following a violent trauma, is a medical emergency. The aim of this study was to investigate the epidemic-clinical profile and report the outcomes of its management. Patients and Methods: This was a 6 years retrospective study, from January 2017 to December 2022, including all patient records of those admitted and treated for traumatic hip dislocation of all types in the Orthopedics and Traumatology Department of the University Hospital of Normandy (CHU-RN). Records of patients discharged against medical advice and incomplete records were excluded. The variables studied were sociodemographic, clinical, therapeutic, and outcome-related. Functional outcome was assessed using the Postel and Merle d’Aubigné score. Results: Our series comprised 36 cases of traumatic hip dislocations out of a total of 1996 admissions, representing a frequency of 1.8%, with a male predominance of 25 cases (69%) and a mean age of 30 years (range: 18 - 47). Road traffic accidents were the most common cause, accounting for 78% of cases. Six cases (17%) had been dislocated previously. Dislocations were of a long-standing nature: 32 were iliac (92%), 1 was sciatic (2.7%), 1 obturator (2.7%), and 2 were central (5.5%). Associated lesions were observed in 14 patients (38.8%), with 16 lesions, predominantly acetabular fractures in 9 cases (25%). Reduction was performed in the emergency department using external manipulation in 30 cases (83%). At a minimum follow-up of 18 months, our results were acceptable in 30 cases (83%). Four cases of coxarthrosis and two cases of osteonecrosis of the femoral head were observed. Conclusion: Hip dislocation is a common trauma emergency. Associated fractures increase the risk of complications. Early diagnosis with urgent reduction improves the prognosis.
