Data Trace Editor – 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: 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
– 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
– Discussion and Indications: – definitive stabilization of frx may be achieved w/ external fixation in certain rotationally unstable but vertically stable injuries; – relative contraindication is iliac wing fractures; – antero-posterior compression injuries: – external fixation is most applicable to stable “open book” … 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
– 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
– 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
– 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: – Extensor Tendon Rupture – Extensor Digitorum Communis – Extensor Mechanism of Digits – Anatomy of EDC: – note that EDC is less tolerant of shortening than FDS due to differential in tendon excursion (50 mm compared to 70 mm, respectively); – references: – The terminal tendon … 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
