Definition
DEXA (Dual-Energy X-ray Absorptiometry) is a low-radiation imaging technique that measures bone mineral density (BMD). In the context of limb lengthening, DEXA scans may be used pre-operatively to assess bone quality, particularly in patients with risk factors for osteopenia or osteoporosis. Low bone density can affect healing time and increase the risk of complications such as delayed union or implant-related problems.
