Summary

This study shows external fixation for hip arthrodesis significantly improves pain and function in adolescents. This method allows weight-bearing during treatment and preserves options for future hip surgeries.

Area of Science:

  • Orthopedic Surgery
  • Pediatric Orthopedics
  • Skeletal Reconstruction

Background:

  • Hip arthrodesis is a surgical procedure to fuse the hip joint, often indicated for severe pain and dysfunction.
  • External fixation offers a method for joint stabilization and fusion, with potential advantages in specific patient populations.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of hip arthrodesis using external fixation in adolescents.
  • To assess functional improvements and complications associated with this surgical technique.

Main Methods:

  • A retrospective review of seven adolescents who underwent hip arthrodesis with external fixation between 1994 and 1998.
  • Follow-up included assessment of time to fusion, duration of fixation, and functional outcomes using the modified Harris hip score.

Main Results:

  • Significant improvement in the mean modified Harris hip score from 25.7 pre-operatively to 66.7 post-operatively (p < 0.01).
  • Mean duration of fixation was 6.6 months, with a mean time to fusion of 8.0 months.
  • Procedure allowed for leg lengthening, preservation of future surgical options, and weight-bearing during treatment.

Conclusions:

  • Hip arthrodesis with external fixation is a viable option for adolescents with intractable hip pain.
  • The technique offers advantages including accurate positioning, potential for limb length equalization, and early mobilization.
  • This method is recommended for carefully selected patients requiring hip fusion.
