Case:
Erdheim-Chester's disease (ECD) is a rare multisystem disorder considered as a neoplasm of non-Langerhans cell histiocytes. We report a case of uncemented total hip arthroplasty in a 74-year-old patient with ECD for femoral neck fracture with pathological involvement of distal metaphysis and diaphysis. We reviewed the literature on bony involvement.
Conclusion:
Adequate osseointegration was achieved in our case; however, longer follow-up is essential. Vigilant reporting of bony involvement, such as pathological fractures, fracture healing, deformities, osteosynthesis, and outcome of joint replacement surgeries, is needed in ECD-like bone diseases.
