Abstract

Background

Tarsometatarsal arthritis is a significant cause of disability and is commonly treated with arthrodesis, which has limitations such as hardware-related complications and adjacent joint stress. Metatarsal base resection-arthroplasty offers a novel, mobility-preserving alternative.

Technique and results

A total of 24 feet were operated on with the BATMAN Technique. Resection consisted of a wedge-shaped resection of the base and dorsal part of the metatarsal, starting approximately 1 cm distal to the joint line with an angle of approximately 45 ° and preserving the plantar hinge. The resection involved the 2nd and 3rd metatarsals in 15/24 feet (62%). Mean follow-up was 51 ± 25.8 months, with favorable outcomes. Complications were limited to metatarsalgia and clinical progression of osteoarthritis on adjacent rays in 4 patients.

Discussion

Metatarsal base resection-arthroplasty seemed to be a safe and feasible technique for managing tarsometatarsal arthritis. Further studies are needed to confirm its efficacy and refine its indications.
