Seven fresh cadaveric specimens were used to determine the loss of forearm rotation with varying distal radius fracture malalignment patterns. Uniplanar malunion patterns consisting of dorsal tilt, radioulnar translation, or radial shortening were simulated by creating an osteotomy at the distal end of the radius, orienting the distal fragment position using an external fixator, and maintaining...

Background: The radial artery is an essential artery supplying the structures in the forearm. Variations in the radial artery concerning its origin, course, branching pattern, and mode of termination have been commonly reported. The high origin of the radial artery from either brachial or axillary artery was detected in numerous studies. Clinically-radial artery is used in cardiac catheterizati...

This study documents the existence and topographic anatomy of a rare case of variant forearm arteries found in the left upper limb of a 68-year-old male cadaver. The arteries of the arm followed typical courses, but both the radial and ulnar arteries in the forearm followed a superficial course. The common interosseous artery and recurrent ulnar arteries branched from the radial, not the ulnar,...

BACKGROUND Isolated radial head dislocation is a rare injury with an unclear pathomechanism, and the treatment is controversial. The purpose of the present study was to investigate the biomechanical contributions of the annular ligament, quadrate ligament, interosseous membrane, and annular ligament reconstructions to proximal radioulnar joint stability. METHODS Five fresh frozen cadaveric up...

BACKGROUND The radial forearm flap is a versatile, widely used flap. However, the possibility of donor site complications has led to concern over its use. Some surgeons prefer using other flaps whose donor sites can be closed primarily with less morbidity, including avoiding unpleasant scarring. However, in our experience, donor site stability of the radial forearm flap can be reliably achieved...

instruction: measurement of brachial artery diameter variation by ultrasound methods has commonly been used to test the endothelial function. it is known that the artery diameter is increased by flow stimulation. therefore in the present study, the effect of external obstruction, as flow stimulation, on the radial strain of the brachial artery was assessed. also the biomechanical behavior of th...

Background: Reconstruction of soft tissue defects of the hand possesses a challenge to the plastic and reconstructive surgeons. In recent years, the radial forearm fasciocutaneous flap has been used extensively to cover hand soft tissue defects. With the routine use of this flap some drawbacks have become apparent. The need to sacrifice the radial artery during the harvest of the flap and the d...

OBJECTIVES Superficial ulnar artery is a vascular anomaly that may be encountered during elevation of forearm flaps for head and neck reconstruction. This anomaly should be considered in patients with a positive Allen's test. STUDY DESIGN Case report and retrospective review of forearm flaps performed at our institution. METHODS A 72-year-old man with a history of total laryngectomy present...

BACKGROUND Treatment of forearm fracture nonunion is challenging. Several surgical techniques for the treatment of forearm nonunion have been reported. OBJECTIVES The aim of this prospective study was to evaluate the effects of the radial forearm bone graft technique in cases with forearm nonunion. PATIENTS AND METHODS We treated 7 patients with forearm nonunions via radial forearm bone fla...
