The tarso-metatarsal 1 joint (TMT-I) arthrodesis is a treatment option or moderate to severe hallux valgus (HV) deformities. Instability of the TMT1 joint is still a debatable indication. Using stable osteosynthesis techniques allows early postoperative weight bearing. Plantar plating combined with a lag screw is the biomechanical most stable construct. An additional intermetatarsal screw can improve the horizontal stability. Clinical results are good and radiological parameters stay constant, even in the long term.
第一跖跗关节（TMT-I）融合术是治疗中重度拇外翻（HV）畸形的一种选择。TMT1关节不稳定仍是一个有争议的适应症。使用稳定的骨固定技术可使患者术后早期负重。跖侧钢板联合拉力螺钉是生物力学上最稳定的结构。额外的跖间螺钉可提高水平稳定性。即使从长期来看，临床效果良好，放射学参数也保持稳定。
