Data Trace Editor – 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: Extensor Pollicis Longus Rupture: – Anatomy: – origin: posterior surface of the middle 1/3 of the ulna & interosseous membrane; – insertion: posterior surface of the base of the distal phalanx of thumb; – action: extends the distal phalanx of the thumb; continued action, extends proximal phalanx and adducts the … Read more
– See: Extensor Tendon Rupture in RA – Discussion: – this tendon is prone to rupture from synovitis and increases friction at Lister’s tubercle second to diseases such as RA and Lupus; – EPL is tendon that is most frequently ruptured from distal radius frx; – if … Read more
