Goal of the study was to evaluate the clinical outcome in cubital tunnel syndrome (CuTS) after partial medial epicondylectomy (pME) with objective parameters.
A retrospective analysis was performed in 29 (18 male/11 female) patients with CuTS who underwent pME. Mean time follow-up was 41.4 months. Parameters assessed sensibility (two point discrimination (2PD) and Semmes Weinstein Monofilaments (SW)) of the fifth finger and grip and pinch strength. In addition, elbow range of motion, elbow instability, medial elbow pain, Froment sign and Tinel`s sign were evaluated.
Postoperative static 2PD of the fifth finger was 12.6 mm. SW values on the operated side (mean 3.58; 2.44-6.65) were comparable to the non-operated side (mean 3.28; 2.44-4.93). Tinel's sign over the ulnar sulcus was positive in 13 cases preoperative and in 16 cases postoperatively. Range of motion of the elbow joint achieved normal values in flexion/extension and pronation/supination with no significant difference in comparison to the non-operated side. Froment sign was positive in 2 cases, negative in 23 cases. Grip strength averaged 48.1 kg in man versus 24.4 kg in women. Pinch strength was 8.6 versus 5.3 kg. Grip strength on the operated side reached up to 91.0% values of the opposite arm.
Good postoperative objective results were reached by pME. pME is an adequate treatment option in CuTS.
本研究旨在通过客观参数评估肘管综合征（CuTS）患者接受部分内侧髁切除术（pME）后的临床疗效。
回顾性分析了 29 例接受 pME 的 CuTS 患者（18 名男性/11 名女性）。平均随访时间为 41.4 个月。评估的参数包括第五指的感觉（两点辨别觉（2PD）和 Semmes-Weinstein 单丝（SW））和握力及捏力。此外，还评估了肘部活动范围、肘部不稳定、内侧肘部疼痛、Froment 征和 Tinel 征。
术后第五指静态 2PD 为 12.6mm。手术侧（平均 3.58；2.44-6.65）的 SW 值与非手术侧（平均 3.28；2.44-4.93）相当。术前有 13 例和术后有 16 例出现尺神经沟处 Tinel 征阳性。与非手术侧相比，肘关节屈伸和旋前/旋后活动范围达到正常，无显著差异。Froment 征阳性 2 例，阴性 23 例。男性握力平均为 48.1kg，女性为 24.4kg。捏力为 8.6 公斤对 5.3 公斤。手术侧的握力可达对侧手臂的 91.0%。
pME 术后获得了良好的客观结果。pME 是 CuTS 的一种有效治疗选择。
