Abstract
Background: A dorsal bunion may occur in nonambulatory adolescents with cerebral palsy (CP) and a Gross Motor Function Classification System (GMFCS) level of IV or V. The deformity can cause pain, skin breakdown, and difficulty wearing shoes and braces. A consensus on the biomechanics and surgical management of dorsal bunions in persons with severe CP has not been established.
Methods: This retrospective cohort study included 23 nonambulatory adolescents with CP, GMFCS level IV or V, and symptomatic dorsal bunions requiring surgery. The median age at surgery was 17 years, and the median follow-up was 56 months. Reconstructive surgery included the excision of a 2 to 3-cm segment of the tibialis anterior tendon to correct the elevation of the first metatarsal. The fixed deformity of the first metatarsophalangeal joint was managed with use of corrective arthrodesis and dorsal plate fixation. Clinical and radiographic outcomes were assessed preoperatively and postoperatively at the transition to adult services.
Results: There were significant improvements in the clinical and radiographic outcome measures (p < 0.001). Pain was relieved, and there were no further episodes of skin breakdown. The elevation of the first metatarsal was corrected from a mean of 3° of dorsiflexion to a mean of 19° of plantar flexion. The deformity of the first metatarsophalangeal joint was corrected from a mean of 55° of plantar flexion to a mean of 21° of dorsiflexion. Six patients had complications, all of which were grade I or II according to the modified Clavien-Dindo system.
Conclusions: The surgical reconstruction of a dorsal bunion via soft-tissue rebalancing of the first ray and corrective arthrodesis of the first metatarsophalangeal joint resulted in favorable medium-term clinical and radiographic outcomes in nonambulatory adolescents with CP.
Level of evidence: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
