Comminuted Weber C Fractures
– Discussion: – comminuted frx of fibula tend to result from high energy injures resulting from direct lateral trauma or vertical loading; – associated injuries include: – impaction frx of lateral tibial plafond; – metaphysis of tibia (Pilon frx); … Read more
Compartment Syndrome
– Discussion: – pathophysiology: – compartment syndrome is elevation of interstitial pressure in closed fascial compartment that results in microvascular compromise; – as duration & magnitude of interstitial pressure increase, myoneural function is impaired & necrosis of soft tissues eventually develops; – intracompartmental pressure: … Read more
Compartment Syndrome Pressure Monitoring
– Discussion: – many surgeon use 30 mm Hg as the cut off for performing fasciotomy; – diastolic pressure: (Whiteside’ Theory): – development of a compartment syndrome depends not only on intra-compartment pressure but also depends on systemic blood pressure; – DBP – CP should be greater than 30 – references: – Diastolic … Read more
Compartment Syndrome of the Foot
– Discussion: – compartment syndromes can occur in the foot as in other parts of body; – mechanism of injury is severe local trauma, & assoc skeletal injury may be minimal; – classic symptoms & signs are progressive pain, numbness in toes, and decreased motion, however, these are the same symptoms … Read more
Collar: in THR
(See also: Total Hip Replacement Menu) Discussion stress transfer to femur is desirable because it provides physiologic stimulus for maintaining bone mass & preventing disuse osteoporosis; if prosthesis has a collar that is seated on the cut surface of the neck or if there is a layer of cement in contact with the bone and undersurface of the … Read more
Colles’ Fracture
– See: Distal Radius Frx Menu / Intra-Articular Fractures of the Distal Radius – General Discussion: – frx was described by Abraham Colles in 1814, originally described as low energy extra articular frx of distal radius occuring in elderly individuals; – frx is typically dorsally displaced and angulated; – mechanism: – fracture is also caused by … Read more
Combined Lesions of the Median and Ulnar Nerves
– See: Nerve Repair: – Discussion: – digit flexors are restored by transferring ECRL to FDP tendons; – FPL is reinforced by Brachioradialis and, in certain instances, the distal joint of the thumb is arthrodesed; – MP joint of the thumb is arthrodesed if this joint is unstable; … Read more
Comminuted Femoral Shaft Fractures – Type IV
– Discussion: – see: Winquist Classification – sign of high energy trauma: more blood loss, systemic complications, and fat embolism syndrome; – all cortical contact is lost; – simple cloverleaf nails are contraindicated w/ type III and IV comminuted frxs because of risk of shortening of frx about nail; – small diameter nails fail to … Read more
Collagen Disorders
– Discussion: – the biosynthesis of collagen involves many complex processes that are subject to biologic control; – these processes can be disrupted at any point by metabolic disorders such as: – scurvy; – lathyrism; – genetic collagen diseases: … Read more
