Alkaptonuria is a rare metabolic disorder. Symptoms include discoloration of tissues and degenerative joint disease and urinary stones. A 60-year-old man was admitted due to knee and hip pain. Brown lesions on the eye, ear, hand and fingers were visible. Limitation of motion of the hip and knee and elbow was present on both sides. He had history of kidney stones ad Achilles tendon rupture. During hip arthroplasty, black lesions on the greater trochanter and femoral head were visible.

Background: The use of pedicle screws in thoracic or lumbar spinal fusion and deformity correction is becoming more privalent, even in children. Improper screw insertion can produce major complications. The accuracy of the screw placement is evaluated post operatively by CT scanning in a small group of children.Methods: In a cross section study, 7 children under 5 years of age who had undergone spinal surgery, using pedicular screws were evaluated in two training hospitals in Tehran, Iran. The position of pedicular screws was determined by an expert radiologist and documented along with probable neurovascular effect.Results: Seven children with total of 42 pedicle screws were assessed. 34 screws (80%) had been placed in the desired positions. The remaining 9 screws had produced minor breakage through the cortices, mainly in narrow thoracic pedicles. There was no case of neurovascular compromise, or stability problem in the 42 screws.Conclusions: Use of peducular screw in spinal fusion of young children is a proper technique.
