Long-term follow-up of bilateral hip and knee arthroplasty secondary to ochronotic arthropathy.

Alkaptonuria is a rare metabolic disorder caused by the deficiency of homogentisic acid oxidase enzyme, which is responsible for eliminating homogentisic acid from the body through the renal system. Excessive accumulation of homogentisic acid leads to ochronosis and ochronotic arthritis. Owing to the rarity of the disease, long-term functional outcomes of joint replacements of the hips and knees in ochronosis arthropathy are unconfirmed, and only a limited number of case reports are available on this.

Revision of type III and type IVB acetabular defects with Burch-Schneider anti-Protrusio cages.

Extensive bone loss in severe acetabular deficiencies can make repair with acetabular shells impossible. We retrospectively analyzed mid-term to long-term results of acetabular revision with Burch-Schneider reinforcement cages in 33 hips in patients with a mean age of 59.03years after a mean follow-up period of 6.

A rare presentation of an intraosseous lipoma in the proximal femur.

Patient: Female, 32 FINAL DIAGNOSIS: Intraosseous lipoma Symptoms: Swelling of the thigh Medication: - Clinical Procedure: Excision of the mass Specialty: Surgery.

Objective: Rare disease.

Background: Intraosseous lipomas happen to be one of rarest benign soft tissue tumors with only a little known about its etiology and pathophysiology.

Total hip arthroplasty in chronic unreduced hip fracture-dislocation.

We treated 15 patients with chronic unreduced hip fracture-dislocations at our hospital; all patients sustained the fracture-dislocations in motor vehicle accidents. All presented to our institution more than 6 months after initial treatment at their local hospitals with uncontained femoral heads; all underwent 1-stage total hip arthroplasty with bone grafting. These patients were monitored for a mean of 71.
