Minimally invasive surgery (MIS) Moberg cheilectomy for hallux rigidus showed no increased complications and improved joint motion compared to open or standard MIS techniques. This technique effectively alters radiographic alignment without compromising early healing.

Area of Science:

  • Orthopedic Surgery
  • Foot and Ankle Surgery

Background:

  • Current literature compares minimally invasive surgery (MIS) cheilectomy to open techniques for hallux rigidus.
  • No studies have evaluated the MIS-Moberg technique against open and standard MIS cheilectomy.

Purpose of the Study:

  • To assess radiological outcomes, early healing, and complications of open, MIS, and MIS-Moberg cheilectomies.
  • To compare the efficacy of MIS-Moberg cheilectomy with traditional open and MIS approaches.

Main Methods:

  • Retrospective cohort review of 134 patients undergoing first metatarsophalangeal (MTP) cheilectomy (2015-2024).
  • Radiographic assessment for surgical success and medical record review for postoperative complications.

Main Results:

  • MIS-Moberg cheilectomy demonstrated statistically significant pre-operative to post-operative changes in dorsal cortical length and sagittal articular P1 angle.
  • Open cheilectomy resulted in hallux rigidus stiffness in 10 patients, while MIS and MIS-Moberg groups had zero cases (P<0.01).

    • Conclusions:

    • Open surgery is associated with a significantly higher rate of plantarflexion and dorsiflexion stiffness compared to MIS and MIS-Moberg techniques.
    • MIS-Moberg cheilectomy effectively modifies radiographic alignment without increasing complications, showing comparable healing rates to open and standard MIS procedures.
