[Recurrent hematomas of the iliopsoas muscle after total hip replacement as a differential diagnosis for chronic groin pain: case series report]

Pseudo-Pelvic Mass

Joint replacement is becoming a more common surgical procedure, and it may have unusual or unexpected postoperative complications. This case report discusses the evaluation of a large pelvic mass first noted on physical examination and ultimately diagnosed by sonography and computed tomography as a chronic hematoma resulting from a failed total left hip arthroplasty.

[Lower limb paresis after total hip arthroplasty. A rare differential diagnosis]

We report on a case of complex nerve damage during total hip arthroplasty. The most severe clinical symptom was proximal leg paresis with diffuse sensory loss. There was an extensive causal Iliopsoas hematoma which developed during the postoperative rehabilitation under therapeutic anticoagulation for atrial fibrillation. An iliopsoas hematoma with subsequent neurological deficits are rare events in the field of hip arthroplasty and a literature review is provided. The treatment of retroperitoneal hemorrhage is controversial but in most instances a conservative approach is favored. The prognosis of neurological damage is sobering as only 20 % of victims are expected to achieve complete restitution.
