In this case report, we describe the clinical features and surgical outcome of cubital tunnel syndrome in adolescent baseball players. Two infielders, 2 pitchers, and 2 catchers who suffered cubital tunnel syndrome during adolescence (average age, 14 years) were surgically treated. Symptoms of medial elbow pain first appeared during throwing in competition games in summer or autumn seasons. After the onset, they suffered limitation of elbow extension and weakness on grabbing balls. They could not throw because of recurrent medial elbow pain. Laxity of the medial collateral ligament was not detected by stress radiography. Duration of symptoms from the onset to surgery was less than 6 months for 2 patients, 1 year for 2, and longer than 2 years for 2 patients. Anterior subcutaneous transposition of the ulnar nerve relieved symptoms up to 3.3 postoperative years. Medial protrusion of the triceps muscle was observed to cause irritation of the ulnar nerve. Fibrosis surrounding the ulnar nerve was observed without pseudoneuroma. Throwing performance returned completely to competitive level in 5 months postoperatively in 5 of 6 patients. Early diagnosis of cubital tunnel syndrome in adolescent baseball players is very important. Anterior subcutaneous transposition of the ulnar nerve relieves symptoms and restores throwing function.
在本病例报告中，我们描述了青少年棒球运动员肘管综合征的临床特征和手术结果。两名内场手、两名投手和两名接球手在青春期（平均年龄14岁）患肘管综合征并接受了手术治疗。内侧肘部疼痛症状首次出现在夏季或秋季的比赛投球过程中。发病后，他们出现肘部伸展受限和抓球无力的情况。由于反复出现内侧肘部疼痛，他们无法投球。应力X线检查未发现内侧副韧带松弛。2例患者从发病到手术的症状持续时间不到6个月，2例为1年，2例超过2年。尺神经前皮下移位术后3.3年症状缓解。观察到肱三头肌内侧突出导致尺神经受到刺激。观察到尺神经周围有纤维化，但无假神经瘤形成。6例患者中有5例在术后5个月时投球表现完全恢复到比赛水平。青少年棒球运动员肘管综合征的早期诊断非常重要。尺神经前皮下移位可缓解症状并恢复投球功能。
