Previous studies have not shown a correlation between knuckle cracking (KC) and hand osteoarthritis (OA). However, one study showed an inverse correlation between KC and metacarpophalangeal joint OA.
We conducted a retrospective case-control study among persons aged 50 to 89 years who received a radiograph of the right hand during the last 5 years. Patients had radiographically proven hand OA, and controls did not. Participants indicated frequency, duration, and details of their KC behavior and known risk factors for hand OA.
The prevalence of KC among 215 respondents (135 patients, 80 controls) was 20%. When examined in aggregate, the prevalence of OA in any joint was similar among those who crack knuckles (18.1%) and those who do not (21.5%; P = .548). When examined by joint type, KC was not a risk for OA in that joint. Total past duration (in years) and volume (daily frequency × years) of KC of each joint type also was not significantly correlated with OA at the respective joint.
A history of habitual KC-including the total duration and total cumulative exposure-does not seem to be a risk factor for hand OA.
之前的研究并未显示指关节弹响(KC)与手部骨关节炎(OA)之间存在相关性。然而,有一项研究表明 KC 与掌指关节 OA 呈负相关。
我们对过去 5 年内接受过右手 X 光检查的 50 至 89 岁人群进行了回顾性病例对照研究。患者手部影像学证实有 OA,而对照组没有。参与者报告了他们 KC 行为的频率、持续时间和细节以及手部 OA 的已知危险因素。
在 215 名受访者(135 名患者,80 名对照)中,KC 的患病率为 20%。综合来看,有 KC 的人(18.1%)和没有 KC 的人(21.5%;P=0.548)任何关节 OA 的患病率相似。按关节类型检查时,KC 并不是该关节 OA 的危险因素。各关节类型的 KC 总既往持续时间(年)和总量(每日频率×年)与相应关节的 OA 也没有显著相关性。
习惯性 KC 的病史——包括总持续时间和总累积暴露量——似乎不是手部 OA 的危险因素。
