Treatment of complex Charcot foot by single stage surgery with static circular fixation. Case series report

Abstract

Objective: We present a case series report of patients with Charcot foot treated by single-stage surgery with static circular fixation.

Material and method: Retrospective review of 10 cases treated with static circular external fixation since 2016, with the following inclusion criteria: 1) Deformity with any of the following: ulcers, osteoporosis, osteomyelitis or instability 2) peripheral neuropathy, 3) failed orthopaedic treatment.

Exclusion criteria: 1) peripheral vascular obstruction without revascularization, 2) inability to comply with treatment, 3) non-ambulatory patients, 4) medical contraindication for surgery. Of the 10patients, 7men and 3women, 6had involvement of the left foot and 4of the right one. The average age of our patients was 58 years (range 39-71). We also evaluated Eichenholtz and Brodsky classification, presence of ulcers, osteomyelitis and instability. All were treated with circular external fixation with a medium follow up of 17 months (11-24 months). Postoperatively we evaluated limb salvation, ulcer healing, stability and re-ulcerations.

Results: In all patients a functional plantigrade foot was achieved, cutaneous ulcer healed without recurrence. Four cases presented superficial pin infection, solved with local wound care. We had wire ruptures in 2 cases, which did not require replacement. We had a traumatic tibial fracture after frame removal, orthopedically solved. All patients were satisfied and would opt for the same technique, if necessary.

Conclusions: of the study In Charcot foot, the objectives are to avoid amputation and achieve a functional plantigrade foot, without ulcer. Single-stage surgery with static circular external fixation is reproducible in our country, and also a valid technique for those cases in which internal fixation may not be the best option.
