[Avascular Necrosis of Femoral Head and Coxarthrosis Progression after Acetabular Fractures].

CONCLUSIONS Confirmed as significant risk factors for the development of posttraumatic avascular necrosis of the femoral head and posttraumatic coxarthrosis progression were the age of 60 and above, posttraumatic medialisation of the femoral head greater than 2 mm, displacement involving the weight bearing area of the acetabulum greater than 2 mm, operative treatment, combined operative approach. At risk are also the transverse fractures (A5 according to the Letournel classification), transverse posterior wall fractures (B2 according to the Letournel classification) and at risk for the development of coxarthrosis are both-column fractures with the high fracture line of the anterior column (C1 according to the Letournel classification). Femoral neck valgosity was a risk factor for the development of femoral head necrosis. Conversely, sex and instability of osteosynthesis detected on the radiograph within 3 months postoperatively were not confirmed as the risk factors for the development of aforementioned complications. To verify the results of this retrospective study other multicentric and prospective studies should be conducted. Key words: complications of treatment of acetabular fractures, risk factors for avascular necrosis of femoral head, risk factors for coxarthrosis. PMID: 31941564 [PubMed - in process]
