CHEVRON OSTEOTOMY

Method
Chevron-shaped corrective osteotomy to correct a hallux valgus
Duration
30 to 60 minutes
Recovery time
6 to 12 weeks

What is a chevron osteotomy?

The chevron osteotomy is an established surgical procedure for correcting a hallux valgus (a bunion). The first metatarsal bone is divided in a V shape and its front part shifted towards the outer side of the foot. The aim is to correct the deformity of the big toe, relieve pain and restore the function of the forefoot.

The chevron osteotomy is often carried out for mild to moderate deformities. It allows a precise correction with a low rate of complications and rapid weight-bearing after the operation. It is usually fixed with a small screw or a mini-plate.

How the operation proceeds

  • Incision over the first metatarsophalangeal joint
  • Chevron-shaped osteotomy of the first metatarsal bone
  • Sideways shift of the distal part of the bone
  • Fixation with a Kirschner wire or a screw
  • Correction of the soft tissue or of accompanying toe deformities where needed

Rehabilitation after a chevron osteotomy

Aftercare following a chevron osteotomy is decisive for the bone to heal successfully and for lasting freedom from symptoms. It proceeds in several phases:

Phase I (0-2 weeks): protection and wound healing
  • Wearing a special shoe to take the load off the forefoot
  • Elevation and cooling to reduce swelling
  • Wound check and changes of dressing
  • No loading of the big toe during roll-off
Phase II (2-6 weeks): functional mobilisation
  • Continuing with the forefoot offloading shoe
  • Physiotherapy to mobilise the big toe
  • Beginning controlled partial weight-bearing
  • Strengthening the intrinsic muscles of the foot
Phase III (6-12 weeks): building up load
  • Changing to comfortable, soft footwear
  • Increasing walking distance and the level of loading
  • Further improvement in movement and co-ordination
  • Manual therapy and gait training
Phase IV (from 12 weeks): return to everyday life
  • Wearing conventional shoes without restriction
  • Sports such as swimming and cycling are possible
  • Avoiding tight, pinching shoes is recommended in the long term
  • Return to work and to sporting activities after discussion with your doctor
