Data Trace Editor – Location of Pin Insertion Sites: – depending on type of frame used, at least two or three pins are placed along iliac wing; – 1st pin is usually placed about 2 cm posterior to anterosuperior spine. – rest of pins should then be placed along iliac crest using … Read more
– See: Over Distraction of Wrist – Discussion: – patient is instructed to move all unaffected joints throughout the joint; – avoid pronation and supination of forearm since this applies skin tension over most proximal screw; (infection is most common here); – when limited finger or … Read more
– Mid-Shaft Humeral Fractures: – consider screw placement in the short frx segment first, since the longer fragment will be more forgiving for shorter or longer screw placement; – take care to avoid injury to axillary nerve proximally and the radial nerve distally; – proximal pin … Read more
– See: – External Fixators for Pelvic Frx – Discussion: – see: vascular injuries in pelvic frx; – theory is that the mobile, sharp edges of frx lead to dislodgment of clotted blood and renewed bleeding; – open book pelvic frx (APC II and APC III) are most … Read more
– General Fixator Considerations: – fracture healing: – references: – Comparison of osteotomy healing under external fixation devices with different stiffness characteristics. – External skeletal fixation of canine tibial osteotomies. Compression compared with no compression. – Comparison of the effects of compression plates and external fixators on … Read more
– See: Extensor Tedon Lacerations – Discussion: – tendon laceration is usually transverse w/ minimal retraction; – often extends into the PIP joint; – lateral bands are often spared, but may be subluxed volarly due to disruption of the triangular ligament; – left untreated, a boutonniere injury … Read more
– See: – Discussion: – if the laceration occurs proximal to the junctura the diagnosis of an extensor tendon laceration can be missed; – have the patient extend the affected proximal phalanx w/ the remaining digits flexed; – lacerations of middle or little digits proximal to … Read more
– Anatomy: – transports APL & EPB tendons; – these tendons represent the radial border of the anatomic snuff box; – when pts thumb is extended, you can distinguish between the tendons as they exit the tunnel; – near insertions of tendons, distal to the tunnel, … Read more
– Discussion: – methods to enhance fixator stability; – in the report by Minor T, et al, 37 femoral shaft fractures, in 33 pediatric patients, were treated with unilateral external fixation after reduction from 1992 through 1998 (ages from 4 to 14 years); – average follow-up was 3 years, … Read more
– See: – Rupture of the Quadriceps – Patellar Tendon Injury – Tibial Tubercle Frx – Discussion: – extensor mechanism includes quadriceps, quadriceps tendon, medial & lateral retinaculum, patellofemoral and patellotibial ligaments, Patellar Tendon (ligament), and tibial tubercle; – superficial location of extensor mechanism make it suseptable to injury; … Read more
