Summary
Subtalar arthrodesis effectively corrects foot deformities like posterior tibial tendon dysfunction and pes planus. This surgical procedure demonstrates a high union rate and low complication risk, offering good patient satisfaction.
Area of Science:
- Orthopedic Surgery
- Foot and Ankle Reconstruction
Background:
- Posterior tibial tendon dysfunction (PTTD) and pes planus often lead to significant foot deformities.
- Subtalar arthrodesis is a surgical option for correcting these complex foot conditions.
Purpose of the Study:
- To evaluate the efficacy and outcomes of subtalar arthrodesis in patients with PTTD and pes planus.
- To assess radiographic and clinical results, including union rates, complication rates, and patient satisfaction.
Main Methods:
- Retrospective study of 21 patients (21 feet) treated with subtalar arthrodesis.
- Screw fixation without bone grafting was utilized for all cases.
- Radiographic measurements and clinical outcomes were assessed at an average follow-up of 3 years.
Main Results:
- Successful bony union was achieved in all patients.
- Significant improvements were observed in tibiocalcaneal angle, arch height, and arch length.
- Excellent or good clinical results were reported in 16 out of 21 feet, with high patient satisfaction.
Conclusions:
- Subtalar arthrodesis is an effective procedure for correcting PTTD and pes planus deformities.
- The technique offers a high union rate, low complication rate, and does not necessitate bone grafting.
- Persistent pain may occur in some patients, particularly those with adjacent joint arthrosis.
