To determine the usefulness of ultrasound (US) in the differentiation of displaced and nondisplaced tears of the ulnar collateral ligament (UCL).
A 7.5-10-MHz linear-array transducer was used to examine 69 patients in whom a UCL tear was suspected, 43 of whom also underwent surgery. The US findings were compared with those obtained at surgery.
Results of US corresponded to results of surgery in 37 of 43 patients. Findings were false-positive in six patients. Twenty-six patients were treated conservatively with thumb casts. These patients showed stability and free range of motion at the first metacarpophalangeal joint at clinical follow-up (9-13 months).
Sonography is useful for evaluating nondisplaced and retracted tears of the UCL and determining the need for surgery.
确定超声（US）在鉴别尺侧副韧带（UCL）移位和未移位撕裂方面的效用。
使用7.5 - 10兆赫的线性阵列换能器对69例疑似UCL撕裂的患者进行检查，其中43例患者还接受了手术。将超声检查结果与手术结果进行比较。
43例患者中，37例超声检查结果与手术结果相符。6例患者检查结果为假阳性。26例患者采用拇指石膏进行保守治疗。在临床随访（9 - 13个月）时，这些患者的第一掌指关节显示稳定且活动范围正常。
超声检查对于评估UCL未移位和回缩性撕裂以及确定是否需要手术很有用。
