Insights

A novel internal fixation system effectively treated a pathological femur fracture in polyostotic fibrous dysplasia (PFD). This minimally invasive approach demonstrated stable fixation and excellent hip function recovery, offering a promising surgical option.

Area of Science:

  • Orthopedics
  • Skeletal Dysplasias
  • Trauma Surgery

Background:

  • Fibrous dysplasia (FD) is a rare bone disorder.
  • Current treatments for FD primarily involve surgery, with limited evidence for pharmacologic agents.
  • A standardized surgical protocol for FD is lacking, highlighting the need for effective surgical strategies.

Purpose of the Study:

  • To report the successful application of a novel bridging combination internal fixation system.
  • To evaluate the efficacy of this system in treating femoral pathological fractures associated with polyostotic fibrous dysplasia (PFD).

Main Methods:

  • A case report of a 29-year-old male with PFD presenting with a subtrochanteric left femur fracture.
  • Application of a bridging combination internal fixation system.
  • Postoperative rehabilitation protocol including functional recovery and progressive weight-bearing exercises.
  • Follow-up using Radiographic Union Scale for Hip (RUSH) scores and hip function scores.

Main Results:

  • The bridging combination internal fixation system provided stable fixation and was minimally invasive.
  • RUSH scores improved significantly from 9 at 1 month to 28 at 6 months post-surgery.
  • Hip function score improved from 28 preoperatively to 88 at 6 months post-surgery, indicating satisfactory healing and functional recovery.

Conclusions:

  • The novel bridging combination internal fixation system is effective for treating femoral pathological fractures in FD.
  • This system offers advantages such as minimal invasiveness, stable fixation, and ease of contouring.
  • It is a potentially viable surgical option for managing such fractures in the future.
