Case:

Isolated capitate fracture nonunion is an uncommon injury that rarely demonstrates concurrent osteonecrosis. The literature to help guide treatment is sparse. We present a 24-year-old woman who developed a nonunion through the capitate waist with concurrent osteonecrosis 15 months after injury. This complication was treated with internal fixation and a capsular-based distal radius vascularized bone graft (VBG) from the fourth extensor compartment artery pedicle. The patient achieved radiographic union by 15 weeks and had near complete recovery of motion and strength at the final follow-up.

Conclusion:

This case supports the use of capsular-based VBG as a technically simple and effective treatment for this rare condition.

Fractures: Bone Repair

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
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 Remodeling and Repair

Bone Remodeling and Repair

Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
