The gradual correction of forearm deformities in multiple hereditary exostoses
1Limb Length Clinics, Gillette Children's Hospital, St. Paul, Minnesota.
Abstract:
Careful preoperative planning, fixator selection and design, surgical technique, and sustained follow-up care are essential for successful gradual correction of pediatric forearm deformities. The sequence of planning gradual deformity correction can be created by establishing a problem list and using this as the basis for design of the gradual correction. Viewing limb length and deformity correction as a "process," rather than a procedure, is of value. Using a hybrid fixation formula that combines half pins with wires can minimize the potential for neurovascular injury. The combination of radial osteotomy, excision of osteochondromas, and gradual ulnar lengthening by distraction osteogenesis improves forearm appearance and function in most patients with multiple hereditary exostoses.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
