The wide range of motion of the thumb derives from the unusual nature of its carpometacarpal joint. Osteoarthritis is common in this joint. Patients may present with variable degrees of pain, reduction of thumb mobility, and joint deformity. Management is based on clinical assessment. Early disease is treated with rest, anti-inflammatory agents or analgesics, intraarticular steroid injections and splints. Since the course of osteoarthritis is often benign, avoiding early invasive treatment is important, except in the presence of proven anatomic deformity.
拇指的广泛活动范围源于其腕掌关节的特殊性质。骨关节炎在这个关节中很常见。患者可能表现出不同程度的疼痛、拇指活动度降低和关节畸形。治疗基于临床评估。早期疾病通过休息、抗炎药或镇痛药、关节内注射类固醇和夹板进行治疗。由于骨关节炎的病程通常是良性的，除了存在已证实的解剖畸形外，避免早期侵入性治疗很重要。
