HOHMANN ARTHROPLASTY
- Method
- Removal of the head of the proximal phalanx in a fixed hammer toe, to reduce pain and correct the position
- Duration
- about 15 to 25 minutes per toe
- Recovery time
- 4 to 6 weeks
What is a Hohmann arthroplasty?
The Hohmann arthroplasty is a well-established surgical technique for treating a hammer toe. The head of the proximal phalanx (P1) of the affected toe is removed, which corrects a painful deformity and reduces problems with pressure. The aim is to straighten the affected toe and make it pain-free without stiffening the whole toe.
How the operation proceeds
- Small incision over the affected toe joint
- Exposure and removal of the head of the proximal phalanx
- Repositioning the toe in a straight alignment
- Fixation with a wire (e.g. a K-wire) for about 4 weeks
- Closure of the wound and dressing
Rehabilitation after an arthroplasty
Targeted aftercare is important following the operation, in order to stabilise the new position and restore the function of the toe.
Phase I (0-2 weeks): immobilisation and wound healing
- Wearing a special forefoot offloading shoe
- Elevation and cooling to reduce swelling
- Avoiding pressure on the affected toe
- Wound checks and changes of dressing
Phase II (3-5 weeks): removal of the wire and mobilisation
- Removal of the fixation wire (after about 4 weeks)
- Beginning careful mobilisation of the toe
- Physiotherapy to improve movement and co-ordination
- Changing to conventional footwear once weight-bearing is cleared
Phase III (from week 6): functional loading
- Return to everyday tasks and to work
- Targeted exercises to strengthen the toe and foot muscles
- Checking how pressure is distributed (with insoles where needed)
- Sporting activities such as cycling and swimming are possible
