内上髁炎是始发于肘内侧髁屈肌旋前肌群的炎症。诊断依据是激发试验。治疗包括休息，冷敷，然后训练和逐步恢复活动。
内上髁炎是任何活动在肘部施加外翻力或涉及强行弯曲前臂掌侧肌肉引起的，如发生在投球，打高尔夫技术不当，打网球（特别是上旋球，用太重的球拍或握得太紧或球拍太小，或重球），和投掷标枪。非竞技活动可引起内上髁炎，包括砌砖、打锤和打字。
内上髁炎的症状和体征
当腕部屈曲或抵抗阻力旋前时，旋前屈肌肌腱（附着在内上髁）和内上髁处有疼痛。
内上髁炎的诊断
激发试验
为确诊，检查者让病人坐在椅子上，将前臂放松置于桌面，手掌向上转动。病人屈腕尽力抬起拳头以克服检查者向下的按压力。内上髁和屈肌腱的起源处疼痛即可诊断。(参见如何检查肘关节。)
内上髁炎的治疗
休息，冷敷，肌肉牵引
动作修正
后期进行阻力锻炼
治疗应根据症状，与肱骨外上髁炎相似。伤者应避免任何引起疼痛的动作。初期给予休息、冷敷、使用非甾体类抗炎药（NSAIDs）和牵引法，少数需要在肌腱周围的疼痛区域注射糖皮质激素。随着疼痛缓解，可进行轻缓的前臂伸肌和屈肌抗阻力锻炼，随之施以偏心和同心圆抗阻力训练。一般仅在保守疗法失败后9～12个月才考虑手术治疗。治疗内上髁炎的外科技术包括去除瘢痕组织和重接受损组织。
