Is congenital thrombotic thrombocytopenic purpura a risk factor for ischemic osteonecrosis of the hip joint (Legg-Calvé-Perthes disease)?

Key Points

To investigate whether congenital thrombotic thrombocytopenic purpura may contribute to ischemic osteonecrosis of the hip joint.
Case report of a 41-year-old patient
Analysis of previous health history
Assessment of outcomes following total hip replacement surgery
Ischemic osteonecrosis observed in a patient with congenital thrombotic thrombocytopenic purpura
Potential link between the two conditions raised
Need for recognition of ischemic osteonecrosis as a possible comorbidity identified

Abstract

Weise et al. reported on a 41-year-old patient previously diagnosed with congenital thrombotic thrombocytopenic purpura undergoing total hip replacement surgery for Perthes disease. This case raises the question whether ischemic osteonecrosis of the femoral head is another so far underrecognized comorbidity causally linked to congenital thrombotic thrombocytopenic purpura.
