Intra-articular Osteoid Osteoma Involving the Femoral Neck in Pediatric Population: A Case Report of 2 Cases.

Introduction: An osteoid osteoma is a benign bone tumor. It is quite common and has become a known entity to most orthopedists and radiologists since it was first reported by Jaffe in 1935. Considering its incidence, it is at third position in the list of most common benign tumors, with prevalence up to 11% among the benign tumors and 3% among primary bone tumors.

Step-cut osteotomy in neglected Monteggia fracture dislocation in pediatric and adolescent patients: A retrospective study.

Introduction: Neglected Monteggia fracture dislocation in children leads to significant restriction of daily activities by causing decreased range of motion at elbow, stiffness, deformity, and neurological compromise. Various treatment strategies have been described in the literature and one of them is ulnar osteotomy combined with reduction of radial head and annular ligament reconstruction.

Aim: The aim of this study was to evaluate the results of step-cut osteotomy without the use of bone grafting with reconstruction of annular ligament in the management of neglected Monteggia fracture dislocation in children.

Rare Presentation of Benign Osteochondroma: A Case Report.

Introduction: Osteochondromas are the most common benign bone tumors (accounting for 20-50% of all benign bone tumors). They are developmental malformations rather than true neoplasms and are thought to originate within the periosteum. They usually affect bones that develop by enchondral ossification and rarely originate from bones that develop by intramembranous ossification such as the scapula, pubic rami, clavicle, and ribs.
