Abstract：
Hallux interphalangeal joint (IPJ) flexion contracture is an uncommon deformity with various underlying causes, including trauma, neurological disorders, and connective tissue pathologies. We present a unique case of a 10-year-old female patient with neurofibromatosis type 1 (NF1) and a history of fibula transposition surgery, resulting in a hallux IPJ flexion contracture. We believe that the loss of the proximal fibular attachment of the extensor hallucis longus (EHL) following fibula harvesting resulted in EHL weakness and unopposed flexor hallucis longus (FHL) pull that eventually led to the contracture. The patient underwent various diagnostic assessments, ruling out other potential causes of the deformity. This case emphasizes the importance of considering previous surgical interventions when encountering flexion contractures of the toes.
摘要：
hallux指间关节（IPJ）屈曲挛缩是一种罕见的畸形，具有各种潜在原因。包括外伤,神经系统疾病,和结缔组织病变。我们介绍了一个10岁女性患者的独特病例，该患者患有1型神经纤维瘤病（NF1）和腓骨转位手术史，导致幻觉IPJ屈曲挛缩。我们认为，腓骨收获后，长伸肌（EHL）的腓骨近端连接丧失，导致EHL无力和无相反的长屈肌（FHL）拉力，最终导致挛缩。患者接受了各种诊断评估，排除畸形的其他潜在原因。这种情况强调了在遇到脚趾屈曲挛缩时考虑先前手术干预的重要性。
