[Large intraosseous ganglion in the femoral condyle treated with resorbable cement: clinical case and differential diagnosis].

We report a case of a very large intraosseous ganglion in a patient with Down's syndrome. The lesion was located in the medial femoral condyle and was diagnosed with imaging techniques (X-rays, CAT scan, bone scan and magnetic resonance imaging) that allowed measuring it. Treatment consisted of curettage and filling of the defect with the skeletal repair system carbonated apatite resorbable cement which allowed for immediate early weight bearing during the postoperative period in a non-cooperative patient.

[Femoral superficial vein thrombosis due to a large iliopsoas bursitis secondary to polyethylene wear debris in total hip arthroplasty].

A 76 year old male patient with a history of implantation of a total hip arthroplasty Perfecta (Orthomet(®)), who presented with an iliac fossa mass, increased diameter of the thigh, and pain during hip flexion and extension. CT and ultrasound show the presence of a giant cystic mass in left iliac fossa about 7 cm in diameter next to the prosthesis. A pseudo-tumour secondary to wear debris after placement of a total arthroplasty is rare.

[Superficial femoral vein thrombosis due to large psoas bursitis secondary to particle disease in total hip arthroplasty].

Male, 76 year-old patient with a history of total hip arthroplasty who presents with a mass in the iliac fossa with swelling of the thigh and hip pain upon flexion and extension. Complementary ultrasound and computed tomography scan studies show a giant lobulated cystic mass in the left iliac fossa, 7 cm in diameter, near the prosthesis. Cyst formation caused by polyethylene disease after total hip arthroplasty is infrequent.

[Thrombosis of the superficial femoral vein due to psoas bursitis secondary to particle disease in total hip arthroplasty].

The case of a male 76 year-old patient with a history of total hip replacement surgery is presented herein. The patient had tumors in the iliac fossa with swelling of the thigh and pain upon hip flexion and extension. The complementary ultrasound and computed tomography show a large lobed cystic tumor in the left iliac fossa, 7 cm in diameter, close to the prosthesis.

Biocompatibility and in vivo gentamicin release from bioactive sol-gel glass implants.

Biomaterial pieces, with suitable osteogenic properties for use in the treatment of bone defects and the capability to avoid bone infections, have been synthesized. These materials are composed exclusively of gentamicin sulfate and bioactive SiO(2)-CaO-P(2)O(5) sol-gel glass (previously synthesized). Implant processing was achieved by uniaxial and isostatic pressure of the components mixture.
