Background
First metatarsophalangeal joint (MTPJ) fusion is the most effective technique for the treatment of MTPJ primary arthritis, severe hallux valgus and failure of primary corrective surgery of these conditions. It can be achieved through different techniques. We evaluated the outcomes in a cohort of patients treated with dorsal plate arthrodesis.
Materials and methods
We treated 30 feet for 28 patients; the mean follow-up was 35 months. For each foot, we collected radiological and clinical assessment, with the visual analogue scale (VAS) for pain and the Manchester and Oxford Foot questionnaire (MOFQ). The technique consisted in a cup and cone arthrodesis with the application of a low profile dorsal plate. Patients were allowed for immediate weight bearing.
Results
Consolidation was achieved in all cases; in 29 cases, radiographic union was recorded within 6 months from surgery, in one case after 9 months. Comparison between the preoperative and postoperative of VAS and MOXFQ values showed a statistically significant difference (p < 0.05). Only one case developed wound dehiscence as complication.
Conclusions
Even if there is still a debate regarding the best system for MTPJ fusion, we believe cup and cone fusion with dorsal plating is an effective method. Moreover, the stability of the osteosynthesis obtained allows for immediate post-operative weight bearing, making patients able to return soon to their normal life.
Trial registration
We present a retrospective study; all patients enrolled were retrospectively registered.
