Summary
Proximal interphalangeal (PIP) joint resection arthroplasty effectively corrects fixed hammertoe deformities, relieving pain and improving alignment. This surgical technique provides reliable, satisfactory outcomes for patients seeking relief from hammertoe issues.
Area of Science:
- Orthopedic Surgery
- Podiatric Surgery
Background:
- Fixed hammertoe deformity is a common condition causing pain and callus formation.
- Surgical correction is often necessary to restore function and alleviate symptoms.
Purpose of the Study:
- To evaluate the long-term efficacy of proximal interphalangeal (PIP) joint resection arthroplasty with Kirschner wire fixation for fixed hammertoe deformities.
- To assess patient-reported outcomes, including pain relief, subjective alignment, and satisfaction.
Main Methods:
- A retrospective review of 63 patients (118 toes) who underwent PIP joint resection arthroplasty for fixed hammertoes.
- Intramedullary Kirschner wire fixation was used in all cases.
- Follow-up averaged 61 months, with assessment of radiographic and subjective outcomes, including AOFAS scores.
Main Results:
- Fusion of the PIP joint occurred in 81% of toes; 19% had fibrous union.
- 92% of patients experienced pain relief, and 84% reported subjective satisfaction.
- Acceptable subjective alignment was achieved in 86% of cases, with good radiographic alignment in 79%.
Conclusions:
- PIP joint resection arthroplasty with Kirschner wire fixation is a reliable surgical technique for correcting fixed hammertoe deformities.
- The procedure consistently yields high levels of patient satisfaction and functional improvement.
- Malalignment and numbness were identified as key factors associated with unsuccessful outcomes.
