Case:
A 17-year-old adolescent boy presented with a pathologic distal femur fracture and bilateral distal femoral metadiaphyseal lytic lesions. Multidisciplinary evaluation confirmed bilateral distal femoral brown tumors associated with primary hyperparathyroidism secondary to a parathyroid adenoma. Treatment included bone biopsy, curettage, grafting, and retrograde locked intramedullary nail, followed by definitive partial parathyroidectomy. The contralateral metadiaphyseal lesion was treated with corrective osteotomy and prophylactic intramedullary stabilization.
Conclusion:
Primary hyperparathyroidism may initially present with symptomatic skeletal manifestations and, rarely, pathologic fracture. Multifocal lytic lesions are a diagnostic red flag which should prompt early biochemical evaluation. In advanced skeletal involvement, prophylactic stabilization can reduce risk of subsequent fracture.

The Parathyroid Glands
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by producing...
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...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
