原发性症状性骨关节炎805例临床分析

IDIOPATHIC SYMPTOMATIC OSTEOARTHRITIS:A CLINICAL ANALYSIS OF 805 CASES

目的：了解汕头地区骨关节炎（ＯＡ）的临床特点和风险因素。方法：记录病史、症状、体征，受累部位除常规Ｘ线照片外，腰椎行ＣＴ检查、膝关节磁共振（ＭＲＩ）检查，资料作综合分析。结果：本地区ＯＡ以腰、颈、膝受累频率最高，手、髋少见；男、女患病率比例１∶２，ＣＴ椎间盘病发现率高于Ｘ线平片，ＭＲＩ有助膝ＯＡ的早期诊断并提供更多信息，并提示膝ＯＡ存在不同类型。结论：本地区手、髋ＯＡ较西方少见；急、慢性损伤为ＯＡ的重要风险因素；膝ＯＡ是一种异质性疾病，治疗宜个别化。

Objective:To study the clinical features of osteoarthritis (OA) in Shantou area,and the possible risk factors of OA.Methods:Medical history,clinical symptoms and signs were recorded,in addition to the routine radiographs of affected joints,CT scan was done for lumbar spine,and magnetic resonance imaging (MRI) was done for knee joints.Results:Lumbar OA,cervical spine OA,and knee OA were prevalent in this area,and hand OA as well as hip OA were less common.More OA cases were seen in woman than man, and the ratio of male to female was 1∶2.CT scan was more sensitive in diagnosing the disc disease than the routine radiograph.MRI was helpful in the early diganosis of knee OA and revealed more abnormalities which suggested that there were different patterns of knee OA.Conclusion: Hand OA and knee OA are less common in Shantou area than in the Western.Acute/chronic trauma is the important risk factors of OA.CT is helpful in the diagnosis of disc diseases.Knee OA is a heterogenic disease,and the treatment should be individualized.
