Summary

Sickle-cell disease (SCD) causes rising rates of avascular necrosis, particularly affecting the shoulder. Early diagnosis is crucial as standard treatments like joint replacement may fail in these patients.

Area of Science:

  • Orthopedics
  • Hematology
  • Radiology

Background:

  • Sickle-cell disease (SCD) is a leading global cause of avascular necrosis.
  • Avascular necrosis of the humeral head is a frequent SCD complication, yet understudied.
  • Prevalence of SCD and its complications are increasing in developed nations.

Purpose of the Study:

  • To investigate the clinical, radiological, and functional shoulder abnormalities in patients with SCD.
  • To assess the prevalence of humeral head avascular necrosis in SCD patients.
  • To evaluate the effectiveness of current management strategies.

Main Methods:

  • Retrospective review of 138 patients diagnosed with SCD.
  • Clinical assessment of shoulder function.
  • Radiological evaluation using a specific classification for shoulder avascular necrosis.
  • Analysis of radiographic lesions and functional outcomes.

Main Results:

  • Radiographic lesions indicative of avascular necrosis were identified in 28% of patients.
  • Lesions were frequently bilateral.
  • Only 53% of patients exhibited normal shoulder function.
  • Management challenges were noted, with joint replacement having a high failure likelihood.

Conclusions:

  • Avascular necrosis of the humeral head is a significant and common complication in SCD patients.
  • Early detection and tailored management strategies are essential for improving patient outcomes.
  • Current treatment options, such as joint replacement, may not be suitable for this population.
