Introduction:
There is limited evidence investigating the use of memory staples for first metatarsophalangeal joint (MTPJ) arthrodesis. This study reports the midterm clinical and functional outcomes of patients who underwent the procedure.
Methods:
A retrospective review of 78 first MTPJ arthrodeses carried out between 2016 and 2018 in the study centre was performed. Patients were followed up via telephone call to complete the Manchester-Oxford Foot Questionnaire (MOXFQ) and service review questionnaire.
Results:
The mean follow-up period was 6.6 ± 0.9 years. The asymptomatic nonunion rate was 2.6 %. The post-operative MOXFQ-index was 12.9 ± 19.5, MOXFQ-pain 12.3 ± 22.6, MOXFQ-walking 16.3 ± 23.8 and MOXFQ-social 9.7 ± 17.3. Eighty-seven percent of patients responded to their toe being better postoperatively. Eighty-four percent of patients were satisfied with the operation. Ninety-five percent of patients felt the operation met their expectations.
Conclusion:
This study has shown that first MTPJ arthrodesis with memory staples is associated with low complication rates and good patient-reported outcomes at midterm follow-up.
