Terms & Conditions of Use

Severe lesser toe deformities often require complex surgical solutions. This study introduces the first 3D-printed metatarsal replacement for a failed prior surgery, offering a novel option for challenging cases.

Area of Science:

Orthopaedic Surgery
Biomedical Engineering
3D Printing Applications

Background:

Severe and recurrent lesser toe deformities present significant surgical challenges.
Traditional salvage options after failed metatarsal head resection are limited, often including amputation.
Advancements in 3D printing technology offer new possibilities for complex reconstructive procedures.

Purpose of the Study:

To present the first case of a 3D-printed second lesser metatarsal replacement.
To demonstrate the utility of 3D printing in addressing complex salvage situations in lesser toe deformities.

Main Methods:

A patient with a failed second metatarsal head resection underwent a novel surgical procedure.
A custom 3D-printed second lesser metatarsal was designed and implanted.

Keywords:

3D printing additive manufacturing joint arthroplasty lesser metatarsal replacement

Surgical technique and outcomes were documented.

Main Results:

Successful implantation of a 3D-printed second lesser metatarsal.
This represents a novel approach to salvage after failed metatarsal surgery.
Demonstrates the potential of 3D printing in orthopaedic reconstruction.

Conclusions:

3D-printed metatarsal replacement is a viable option for severe, recurrent lesser toe deformities.
This technology expands therapeutic options for challenging orthopaedic cases.
Further research is warranted to evaluate long-term outcomes of 3D-printed implants in foot surgery.
