First metatarsophalangeal joint arthrodesis.

Area of Science:

• Orthopedic Surgery
• Podiatric Medicine
• Foot and Ankle Reconstruction

Background:

• First metatarsophalangeal joint (MTPJ) arthrodesis is a common procedure for debilitating foot conditions.
• Hallux rigidus, characterized by pain and stiffness, is a primary indication for MTPJ arthrodesis.
• Other indications include rheumatoid arthritis, failed implants, fractures, avascular necrosis, and infections.

Purpose of the Study:

• To outline the indications and essential technical goals for successful first MTPJ arthrodesis.
• To emphasize the importance of achieving stable fixation and proper joint positioning.
• To highlight the role of MTPJ arthrodesis in restoring foot function and patient mobility.

Main Methods:

• Review of current literature and surgical principles for first MTPJ arthrodesis.
• Analysis of key biomechanical and functional outcomes associated with the procedure.
• Discussion of essential surgical considerations for optimal patient results.

Main Results:

• First MTPJ arthrodesis effectively addresses pain and deformity in hallux rigidus.
• The procedure serves as a valuable salvage option for complex foot pathologies.
• Achieving stable fixation and appropriate joint alignment is crucial for functional recovery.

Conclusions:

• First MTPJ arthrodesis is a reliable treatment for end-stage hallux rigidus and other severe MTPJ conditions.
• Successful outcomes depend on achieving stable fixation, optimal joint positioning, and maintaining foot length.
• This surgical fusion provides a stable plantigrade foot platform, enhancing gait and quality of life.
