Data Trace Editor Discussion (Humeral Shaft Frx ») Forces Displacing the Fracture components of a well designed cast brace include an anterior component w/ a bicipital contour and a posterior component w/ a flat mold for the triceps; velcro straps maintain adequate compression; in closed humeral shaft fractures involving the middle or proximal thirds, about 95% of patients … Read more
– Discussion: – cast syndrome results from obstruction of third portion of the duodenum by superior mesenteric artery leading to high intestinal obstruction; – in the past, it occurred most often following Harrington rod instrumentation for scoliosis which was followed by application of a body cast; – Clinical Findings: – typical presentation: is abdominal pain, distension … Read more
– Indication for Closed Treatment: – indications — These are based on “personality” of the fracture as described by Nicoll EA (1964) – he listed factors favoring union: – displacement: if the fracture fragments on are or can be opposed to 25% in a transverse fracture, casting or bracing is permissible – more than 50% initial frx … Read more

– See: Metacarpal Extra-articular Base Frx – Discussion: – relatively mobile ring and little CMC joints are more susecptible to dislocation than the immobile index and long rays; – fifth CMC is the most frequently injured; – pertinent anatomy: – ring and little metacarpals articulate w/ … Read more
Discussion growth involves either or both of two processes; Appositional Growth new cartilage is formed at cartilage surface by cells derived from chondroblasts of perichondrium; w/ maturation, majority of cartilage growth is primarily appositional; Interstitial Growth increase in internal mass of cartilage by activity of chondrocytes that multiply within their lacunae; in mature cartilage, cellular turnover … Read more

– Discussion: – cartilage end plate contains no fibrillar connection w/ collagen of subchondral bone of the vertebrae; – this lack of interconnection between end plate and the vertebrae may render disc biomechanically weak against horizontal shear forces; – outer 2/3 of annulus fibrous are firmly anchored into vertebral bodies; … Read more
