Striding Ahead—Functional Outcomes of First Metatarsophalangeal Joint Arthrodesis Using Low-profile Dorsal Plate Fixation: A Comparative Study
Year: 2026
Type: article
Abstract: Despite the loss of motion at the fused joint, first MTP arthrodesis has shown to achieve high fusion rates, substantial pain relief, and satisfactory functional outcomes.Postsurgical assessments reveal that over 90% of patients report significant improvement in pain, often leading to a marked increase in daily activities and quality of life.Moreover, fusion rates are consistently high, with studies reporting success rates between 90 and 98%, contributing to durable and long-term joint stability.5 However, concerns remain regarding the procedure's impact on gait mechanics and plantar IntroductIonThe first metatarsophalangeal (MTP) joint plays a crucial role in foot mechanics, particularly in providing balance, stability, and effective propulsion during gait.As a synovial hinge joint, the first MTP joint comprises the convex articular surface of the first metatarsal (MT) head articulating with the concave base of the proximal phalanx, both of which are covered by articular cartilage to facilitate smooth movement and reduce friction.1 Several ligaments, including the collateral ligaments, plantar plate, and dorsal ligament, reinforce the joint capsule and contribute to the stability of the joint.Additionally, the sesamoid apparatus, embedded within the tendons of the flexor hallucis brevis, serves as a mechanical pulley to enhance leverage during toe-off phases in gait, ultimately reducing friction on the tendons. 2 Due to its critical role in weight-bearing and propulsion, the first MTP joint is vulnerable to various pathologies that can severely affect functionality and quality of life.Conditions such as hallux valgus, hallux rigidus, and deformities from rheumatoid arthritis often result in pain, limited joint mobility, and progressive joint degeneration.3 For patients experiencing advanced disease or deformity that does not respond to conservative management, surgical intervention is often indicated.Arthrodesis, or surgical fusion, of the first MTP joint is a well-established treatment for alleviating pain, correcting deformities, and restoring functional stability, especially for patients with severe degenerative changes.
