Melorheostosis in an Adolescent with Limb Length Discrepancy and Management with Epiphysiodesis with Eight Plates.

INTRODUCTION: Melorheostosis is a rare bone dysplasia. It is mainly a radiographic diagnosis with distinct findings of endosteal or periosteal sclerosis along the axis of long bones, resembling the flowing wax. It is usually polyostotic and monomelic. Clinical manifestations are pain, limitation of joint movements, deformities, and contractures. Leg length discrepancy may be found, usually the affected limb being shorter. CASE PRESENTATION: We present an adolescent boy, with melorheostosis of the lower limb. The affected limb was longer with equally divided discrepancy of the femur and tibia. There were no another symptoms. After a thorough investigation, we performed epiphysiodesis both medial and lateral of the distal femoral and proximal tibial growth plate, using8eight plates. At the end of the growth, there was almost complete equalization of the length of his lower limbs. CONCLUSION: Melorheostosis may be present with leg length discrepancy leg length discrepancy, with an exception, being that the affected limb is longer. Epiphysiodesis with eight plates is an effective method of limb length equalization.

Solitary osteochondroma of the capitate, in a child.

Osteochondromas, are the most common tumors of the long bones in children. Osteochondromas are extremely rare in the carpal bones. They are diagnosed in adult life, in almost all cases in the literature. We report a 7 year old boy, who presented with a hard mass on the dorsum of his hand, with decreased wrist movements. Radiological examination showed a calcified tumor of the second row of the carpal bones, with spherical shape and covered with cartilage. He was surgically treated with removal of a cartilaginous mass that was arising from the capitate. Pathology confirmed the diagnosis of an osteochondroma.

Osteoid osteoma of the acetabulum: diagnosis and medical treatment.

We describe the medical management of an acetabular osteoid osteoma in an 11-year-old girl. There was a 2-year delay until proper diagnosis of the patient's pathology was made. Accurate localization of the nidus in the subchondral bone, involving the cartilage, is difficult on the basis of plain radiographs. All imaging methods, including computed tomography, MRI, and bone scintigraphy, were used to confirm the diagnosis. We proposed medical treatment to avoid possible severe complications from surgical intervention. At the patient's latest follow-up visit, after 2 years of medical treatment with NSAIDs, there is complete healing of the osteoid osteoma and there is no sign of recurrence.
