midshaft
Long bone's midsection
Midshaft refers to the middle portion of a long, narrow structure—most commonly the central section of a bone between its two ends: a midshaft fracture of the femur.
The term appears primarily in medical and anatomical contexts, describing the location of breaks, tumors, or other conditions along tubular bones like the humerus, tibia, or fibula.
