Surgery Performed by Supervised Trainees Does not Affect Outcome in First Metatarsophalangeal Joint (MTPJ)...

First metatarsophalangeal joint (MTPJ) arthrodesis is an index procedure for orthopedic trainees in the United Kingdom. There is an absence of evidence as to the outcome of surgery when performed by supervised trainees. The aim of this study is to compare the incidence of fusion, complication rate and radiographic outcomes in first MTPJ arthrodesis performed by supervised orthopedic trainees with consultants. This is a retrospective cohort study of 117 patients undergoing first MTPJ arthrodesis from August 2015 to December 2017 in our institute for hallux valgus (HV) deformity with first MPTJ arthrosis or for hallux rigidus. Patients were followed to a minimum of 1-year postsurgery and were given an open appointment thereafter. In the hallux rigidus group, there was no significant difference between the complication rate (p = .477), incidence of fusion (p = .663), postoperatively HVA (p = .763), and postoperative intermetatarsal angle (p = .539) between trainees and consultants. There was a significant difference in mean tourniquet time (p = .563) between trainees and consultants. In the hallux valgus group, there was no significant difference in the complication rate (p = .519), incidence of fusion (p = .786), tourniquet time (p = .075), postoperative HVA (p = .423), and postoperative intermetatarsal angle (p = .143) between the trainees and consultants. This is the first MTPJ fusion series that demonstrates good results can be achieved by supervised trainees performing the procedure. This would suggest that first MTPJ arthrodesis remains an opportunity for trainees to continue learning to perform under supervision whilst ensuring no change in outcome for the patient.
