Abstract
BackgroundArthrodesis of the first metatarsophalangeal joint (MTPJ) is a frequently performed surgical procedure. Many patients have bilateral hallux MTPJ pathology requiring bilateral arthrodesis. There are concerns that bilateral simultaneous hallux surgery, under one anaesthetic, results in the patient being severely incapacitated in the early post-operative period. We hypothesize that bilateral simultaneous hallux MTPJ fusions does not compromise outcomes or the patients’ post-operative comfort and rehabilitation and is cost and time effective. MethodsIn this retrospective study, 16 patients who underwent bilateral simultaneous first MTPJ arthrodesis were compared to 16 patients who had unilateral MTPJ arthrodesis with regards to outcome, tolerance, cost and time effectiveness. Outcome measures were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) hallux score and the Self-Reported Foot and Ankle questionnaire (SEFAS). ResultsThere was a significant improvement in the AOFAS scores post surgery in the bilateral group and according to the SEFAS grading, 14 patients (87.5%) had good or excellent outcome scores with 13 (81.25%) of these patients having excellent scores. This was comparable to the outcome scores in the unilateral group. Two patients developed non-unions bilaterally compared to one in the unilateral group. There is also a notable general cost saving and less time off work when bilateral fusions are done at the same setting. ConclusionBilateral simultaneous hallux MTPJ arthrodesis is an effective, convenient and cost effective option for patients requiring MTPJ fusions for bilateral hallux pathology.
