Hallux limitus/rigidus deformity: a new great toe implant

Area of Science:

• Orthopaedic surgery
• Biomedical engineering
• Podiatric medicine

Background:

• Hallux limitus/rigidus is a common degenerative joint disease affecting the first metatarsophalangeal (MTP) joint.
• Traditional surgical treatments include cheilectomy, osteotomy, arthrodesis, and implant arthroplasty.
• Hinged implants have been widely used but are susceptible to mechanical failure.

Observation:

• A novel two-component Bioaction great toe implant has been developed.
• This design aims to enhance durability and reduce the risk of implant breakage.
• The implant is intended as an alternative to existing treatment options for hallux limitus/rigidus.

Findings:

• The Bioaction implant's two-component structure suggests improved resilience against mechanical stress.
• Preliminary observations indicate potential superiority over single-component hinged implants in terms of longevity.
• Case presentation will illustrate the clinical application and outcomes of the Bioaction implant.

Implications:

• This implant may offer a more durable solution for patients with hallux limitus/rigidus.
• It could potentially reduce revision surgery rates associated with implant failure.
• Further clinical studies are warranted to validate long-term efficacy and patient outcomes.
