Background: First MTP joint arthrodesis is a well established and very common procedure for painful arthrosis. Plate fixation method has been used with successful outcome (97–100%) by few authors but it is yet to be accepted universally for fear of complications.

Aim: To evaluate clinical and radiological outcome of first MTP fusion using low profile Acumed plate.

Methods: We retrospectively reviewed 125 patients who had 1st MTP arthrodesis (over 6 year period) for painful Hallux Rigidus not relieved by conservative means and for rheumatoid forefoot reconstruction. The preoperative evaluation included a subjective questionnaire, physical exam, AOFAS hallux score and radiographic measurements. Post-operatively, all patients were mobilised with heel weight bearing shoes for six weeks. All patients had follow up of minimum 6 months(range 6 months to 6 years). At the final follow-up all patients had answered a questionnaire which evaluated any limitations of daily activity and restrictions in footwear. Radiological measurements included union of the arthrodesis and various angles (valgus, intermetatarsal and dorsiflexion).

Results: Of the 125 patients we had final reviews for 103 patients. The mean AOFAS improved from 40 to 82. The individual components of AOFAS i.e. pain, walking ability and alignment improved significantly. All patients but one had radiological evidence of fusion at mean of 6 weeks (range 6–8weeks) allowing them to walk with normal footwear. The mean dorsiflexion angle was 15° (range 13 °–18 °). The patient with non-union had re-arthrodesis with bone grafts using the revision plate. Two patients with rheumatoid arthritis required removal of plate for infection and wound breakdown. No plate failure occurred in any of the patients.

Conclusion: The plate fixation is a reliable method for 1st MTP joint fusion that allows for a predictable fusion in a satisfactory alignment with low complication rate. The stability of the fixation allows for early mobilization without need for plaster immobilization and early return to functional activities.
