Hammertoes: Anatomy, Pathophysiology, and Comprehensive Treatment Strategies

Hammertoe is a common foot deformity that originates from the proximal interphalangeal joint of the lesser toes. The deformity involves an imbalance between the muscles and tendons that control toe movement, leading to deformity. Hammertoes can result from various factors, including genetic predisposition, ill-fitting footwear, trauma, or underlying medical conditions such as neuromuscular disorders or diabetic neuropathy. As the deformity progresses, patients may experience pain, difficulty walking, and development of corns or calluses on the affected toes. Treatment strategies for hammertoes range from nonsurgical to surgical, depending on the severity of discomfort and effect on patient function. Nonsurgical treatment includes wearing appropriate footwear, using orthotic devices, and performing targeted exercises to strengthen and stretch affected muscles. In more advanced cases, surgical options, such as tendon transfers, joint arthrodesis, or arthroplasty, may be considered. A comprehensive understanding of hammertoe anatomy, pathophysiology, and treatment options is crucial for the effective management of this condition.
