Of ten patients with lacerations of the flexor hallucis longus tendon, nine were athletically inclined. In four, the laceration was not repaired and no disability was evident. A functioning flexor hallucis longus, therefore, does not seem to be essential for good push-off and balance in running sports. If both the flexor hallucis brevis and the flexor hallucis longus are lacerated and reconstitution of the longus is not possible, the brevis should be repaired, suturing the distal segment of the longus to brevis to prevent hyperextension deformity of the metatarsophalangeal joint. Hypersensitivity of the scar due to associated nerve injury is a frequent complication associated with laceration of the flexor hallucis longus.
在10例拇长屈肌腱撕裂伤患者中，9例有运动倾向。其中4例未修复撕裂伤，且未出现明显功能障碍。因此，对于跑步运动中的良好蹬地和平衡而言，正常功能的拇长屈肌似乎并非必不可少。如果拇短屈肌和拇长屈肌均发生撕裂且无法修复拇长屈肌，则应修复拇短屈肌，将拇长屈肌的远侧断端缝合至拇短屈肌以防止跖趾关节过伸畸形。由于相关神经损伤导致的瘢痕过敏是拇长屈肌撕裂伤常见的并发症。
