Tarso-metatarsal 1 joint (TMT-I) arthrodesis effectively treats hallux valgus. Stable osteosynthesis, particularly plantar plating with lag and intermetatarsal screws, enables early weight-bearing and yields good long-term outcomes.

Area of Science:

  • Orthopedic surgery
  • Foot and ankle reconstruction
  • Surgical innovation

Background:

  • Hallux valgus (HV) deformities often require surgical intervention.
  • Tarso-metatarsal 1 joint (TMT-I) arthrodesis is a viable treatment for moderate to severe HV.
  • TMT-I joint instability as an indication for arthrodesis remains debated.

Purpose of the Study:

  • To evaluate the efficacy of stable osteosynthesis techniques for TMT-I arthrodesis.
  • To assess the biomechanical stability of different fixation methods.
  • To determine the clinical and radiological outcomes of early weight-bearing protocols.

Main Methods:

  • Utilized stable osteosynthesis techniques for TMT-I arthrodesis.
  • Employed plantar plating combined with a lag screw as the primary construct.

  • Investigated the addition of an intermetatarsal screw for enhanced horizontal stability.

    • Main Results:

    • Plantar plating with a lag screw provides the biomechanically most stable construct.
    • An additional intermetatarsal screw further improves horizontal stability.
    • Clinical results are consistently good, with stable radiological parameters long-term.

    Conclusions:

    • Stable osteosynthesis techniques, especially plantar plating with lag and intermetatarsal screws, are effective for TMT-I arthrodesis.
    • These methods facilitate early postoperative weight bearing.
    • The technique demonstrates reliable and durable clinical and radiological outcomes for hallux valgus.
