Surgical reconstruction of severe forefoot derangement in a patient with traumatically acquired contralateral limb-length discrepancy: a case report.

Limb-length discrepancy is a very common condition. A severe debilitating forefoot deformity resulting from a post-traumatic limb length discrepancy is quite rare. This case study discusses the surgical reconstruction of a forefoot deformity of a 64-year-old male following a post-traumatic limb-length discrepancy from a motor vehicle accident that caused compensatory biomechanical changes in the unaffected lower extremity. These changes resulted in a severe hallux abducto valgus deformity with subluxated metatarsophalangeal joints of the second and third digits, leaving the patient with a severe symptomatic forefoot deformity that closely mimics the radiographic appearance of a rheumatoid forefoot. The forefoot deformity was corrected using the Mckeever and Hoffman procedures with Kirschner-wire fixation. Seven months following the corrective procedures, the patient was able to obtain an asymptomatic plantigrade foot and can now wear regular footwear.
