Masquelet technique for treatment of segmental bone loss in the upper extremity.

A relatively simple technique to address large segmental bone defects in the upper extremity is described, along with a case example.

Surgical Management of Symptomatic Olecranon Traction Spurs.

Background: There is a paucity of information pertaining to the pathoanatomy and treatment of symptomatic olecranon traction spurs.

Purpose: To describe the pathoanatomy of olecranon traction spur formation, a technique for spur resection, and a series of patients who failed conservative care and underwent operative treatment.

Study Design: Case series; Level of evidence, 4.

Mg ATP and antioxidants augment the radioprotective effect of surfactant copolymers.

Mediated by reactive oxygen species, the damaging effects of high-intensity ionizing irradiation on tissues are dose, frequency, oxygen concentration, and tissue property dependent. Intense ionizing irradiation exposure may cause rapid cellular necrosis by peroxidation of membrane lipids leading to membrane disruption. This leads to a loss of the transmembrane ionic gradients and a subsequent depletion of the cellular ATP store, followed by cellular generation of reactive oxygen species.
