title: Metatarsal extension osteotomy without plantar aponeurosis release in cavus feet. The effect on claw toe deformity a radiographic assessment.
abstract: BACKGROUND
  This study reviewed patients undergoing correction of cavus foot deformity by metatarsal extension osteotomy with preservation of the plantar aponeurosis, and assessed the correction achieved of the claw deformity of the toe by radiographic assessment.
  
  
  METHODS
  15 patients (18 feet) were reviewed clinically and radiographically. All feet required extension osteotomy of the first metatarsal and four patients (5 feet) had extension osteotomy of the first to fourth metatarsals. Hallux extension angle in relation to the 1st metatarsal and in relation to the ground was measured in all feet to estimate the degree of clawing of the hallux.
  
  
  RESULTS
  13 patients (15 feet) were satisfied with the outcome of their surgery and also the appearance of their foot. The mean radiographic change in the hallux extension angle in relation to the 1st metatarsal was 16°, and in relation to the ground was 7°. These changes were statistically significant.
  
  
  CONCLUSIONS
  Our results indicate an improvement in the claw toe deformity and we recommend preservation of the plantar aponeurosis in corrective surgery for cavus foot.
