To study the epidemiological and clinical aspects of osteoarthritis (OA) of the hip in Ouagadougou, as well as its risk factors.
This retrospective study covered cases treated over a 3-year period (February 2006 through January 2009) in the internal medicine department of the Yalgado Ouedraogo Teaching Hospital of Ouagadougou (Burkina Faso) and the surgery department of the private hospital Notre-Dame-de la Paix of Ouagadougou. All patients included had OA of the hip that met the Kellgren and Lawrence criteria.
There were 46 patients who met the study criteria, but only 40 files could be used. The patients' mean age was 46.4 years ± 15.2 years (range 25-80 years; 10 patients were older than 56 years). Men accounted for more than half (n=23, 57.5%). The mean duration of disease was 6.2 years ± 4.5 years (range: 1-19 years). The right hip alone was concerned in 20 patients (50%), the left hip in 16 (40%), and the OA was bilateral in four (10%). Seventeen patients had sickle cell disease (42.5%), 11 SC and 6 SS. The risk factors included necrosis of the femoral head in 19 cases (59.37%), hip dysplasia in 6 (18.74%), hip trauma in 3 (9.37%), inflammatory arthropathy in 3 more (9.37%), and epiphysitis in one (3.13%). The OA of the hip was primary in 8 cases (20%). Three patients were at stage 1, 9 at stage 2, 15 at stage 3, and 13 at stage 4 according to the Arlet-Ficat classification.
OA of the hip arises in a young population and is dominated by secondary OA. The dominant risk factor was aseptic necrosis of the femoral head associated with sickle cell disease. In view of the small number of patients with primary OA, no definitive conclusions can be drawn about it.
研究瓦加杜古髋骨关节炎（OA）的流行病学和临床特征及其危险因素。
这项回顾性研究涵盖了在瓦加杜古（布基纳法索）的亚尔加杜·韦德拉奥戈教学医院内科和瓦加杜古圣母和平私立医院外科在3年期间（2006年2月至2009年1月）治疗的病例。所有纳入患者的髋骨关节炎均符合凯尔格伦和劳伦斯标准。
有46例患者符合研究标准，但仅40份病历可供使用。患者的平均年龄为46.4岁±15.2岁（范围25 - 80岁；10例患者年龄超过56岁）。男性占一半以上（n = 23，57.5%）。疾病的平均持续时间为6.2年±4.5年（范围：1 - 19年）。仅右侧髋关节受累的患者有20例（50%），左侧髋关节受累的有16例（40%），双侧受累的有4例（10%）。17例患者患有镰状细胞病（42.5%），其中11例为SC型，6例为SS型。危险因素包括19例（59.37%）股骨头坏死、6例（18.74%）髋关节发育不良、3例（9.37%）髋部创伤、另外3例（9.37%）炎性关节病以及1例（3.13%）骨骺炎。髋骨关节炎为原发性的有8例（20%）。根据阿莱特 - 菲卡特分类，3例患者处于1期，9例处于2期，15例处于3期，13例处于4期。
髋骨关节炎在年轻人群中发病，继发性骨关节炎占主导。主要危险因素是与镰状细胞病相关的股骨头无菌性坏死。鉴于原发性骨关节炎患者数量较少，关于其无法得出明确结论。
