Area of Science:

  • Orthopedic Surgery
  • Foot and Ankle Reconstruction
  • Biomechanical Correction

Background:

  • Severe rigid equinus deformity in adults presents a significant clinical challenge.
  • U-osteotomy combined with Taylor Spatial Frame is a rarely reported but potentially effective treatment.
  • Evaluating this technique is crucial for managing complex foot deformities.

Purpose of the Study:

  • To assess the effectiveness and efficacy of U-osteotomy with Taylor Spatial Frame for correcting severe rigid equinus deformity in adults.
  • To evaluate the radiologic and functional outcomes of this surgical approach.
  • To determine patient satisfaction rates following the procedure.

Main Methods:

  • Retrospective review of 30 feet in 26 adult patients treated with U-osteotomy and Taylor Spatial Frame.
  • Radiologic assessment using anterior tibiotalar angle (TTA) on weightbearing radiographs.
  • Functional evaluation via American Orthopaedic Foot & Ankle Society (AOFAS) scores and Likert scale patient satisfaction.

Main Results:

  • Significant improvement in TTA (P < .001) from a median of 157.5 to 113.5 degrees, achieving plantigrade feet in most cases.
  • Substantial increase in AOFAS ankle and hindfoot scores (P < .001), from a median of 51.0 to 76.0.
  • High patient satisfaction reported, with 83% (24/30) of patients being very or somewhat satisfied.

Conclusions:

  • Minimally invasive U-osteotomy with Taylor Spatial Frame is an effective and relatively safe method for gradual correction of severe adult rigid equinus deformity.
  • The technique demonstrates significant improvements in radiographic alignment and functional scores.
  • High patient satisfaction rates support its utility in complex foot and ankle reconstruction.
