Decreased activity in the greater trochanter physis on bone scintigraphy can predict hip chondrolysis in slipped capital femoral epiphysis (SCFE). This imaging technique allows for earlier detection and potential intervention in SCFE patients.

Area of Science:

  • Orthopedics
  • Pediatric Orthopedics
  • Radiology

Background:

  • Premature closure of the greater trochanter physis is a known predictor of chondrolysis in slipped capital femoral epiphysis (SCFE).
  • Early identification of chondrolysis is crucial for managing SCFE and potentially altering disease progression.

Purpose of the Study:

  • To investigate the utility of bone scintigraphy in detecting changes in the greater trochanter physis associated with chondrolysis in patients with SCFE.
  • To determine if scintigraphic findings can precede radiographic evidence of chondrolysis.

Main Methods:

  • Bone scintigraphy was performed on patients with SCFE.
  • Scans were analyzed for activity in the greater trochanter physis.
  • Findings were correlated with the presence or absence of chondrolysis and radiographic changes.

Main Results:

  • Sixteen patients with SCFE and concurrent or developing chondrolysis showed decreased activity in the greater trochanter physis on bone scintigraphy.
  • In five patients, this scintigraphic pattern preceded radiographic signs of chondrolysis.
  • Thirteen patients with SCFE but without chondrolysis had normal scintigrams and open physes on radiographs.

Conclusions:

  • Bone scintigraphy can identify decreased activity in the greater trochanter physis in SCFE patients with chondrolysis.
  • This imaging modality may allow for earlier recognition of chondrolysis than traditional radiography.
  • Earlier detection of chondrolysis in SCFE offers potential for improved management and outcomes.
