Data Trace Editor – Green Stick Fractures: – anterior cortex becomes impacted, & posterior cortex is frx w/ torn periosteum; – there is a visible recurvatum deformity; – Treatment: – reduction w/ general anesthesia because considerable force is required to stretch the anterior cortex; … Read more
– Work Up: anesthesia, medical considerations, and timing of surgery – X-rays for Femoral Neck Frx – Operative Techniques: Cannulated Screws: IM Nailing and Sliding Hip Screws for Femoral Neck Frx Hemiarthroplasty Open Reduction of Femoral Neck Fracture Anesthesia and Timing for Femoral Neck Fractures Antibiotic Prophylaxis … Read more
– Lesser Trochanteric Fracture: – isolated fracture of the lesser trochanter is quite rare but may develop as a result of the avulsion force if the iliopsoas muscle; – it occurs commonly as a component of intertrochanteric fracture; – frx of the lesser trochanter along with a subtroch or intertroch fracture … Read more
– Discussion: – frx is associated w/ injury to arterial supply of minor fragement; – this may be manifestated by AVN; – vascular supply to proximal scaphoid: – proximal two thirds to three fourths of scaphoid is supplied by vessels entering dorsal surface; … Read more
– See: – Lateral Collateral Ligament – Maisonneuve Fracture – Discussion: – occur most often in association w/ proximal tibial fractures, esp w/ split compression, bicondylar, and subcondlylar fractures; – look for injury to peroneal nerve, anterior tibial artery, biceps tendon, & lateral collateral ligament; … Read more
– Discussion: – two processes, lateral & posterior, project from body of talus – either process may be fractured, either as isolated injury or assoc w/ other ankle or talar injuries; – diff dx of posterior ankle pain: (os trigonum) – embryology: … Read more
– Discussion: – small fractures of the coronoid process itself are unimportant; – large coronoid fractures involve the distal articular surface of trochlear notch which can lead to significant instability of elbow in extension; – these frx require plate to neutralize forces across site of comminution; – frx … Read more
– Discussion: – occurs in children between ages of 6-10 yrs who sustain injury by falling on an outstretched hand; – shearing forces of hyperextension & supination displace the distal radial epiphysis dorsally; – great majority are Salter I and II: – physeal … Read more
– Discussion: – hip dislocations are typically caused by high-energy trauma, usually from motor-vehicle accidents. – they occur most frequently in young patients; – types of dislocations: – anterior dislocation – central acetabular fracture dislocations … Read more
– See: – Anterior Dislocation of the Shoulder – Posterior Shoulder Dislocation – Proximal Humeral Fracture – Three Part Fracture Dislocation – Discussion: – frx dislocations may be considered an extension of two, three, and four part frx classifictions; … Read more
