Discussion frx of radial shaft (between middle and distal 1/3’s) & dislocation of distal radioulnar joint; usually the dislocation is dorsal, but in some cases can be palmar; frx is almost always located just above proximal border of pronator quadratus; usually there is anterior angulation w/ transverse or short oblique config; ref: A Historical Report … Read more
– Treatment in Children: – frx is usually displaced dorsally and shortened in bayonette position; – due to the significant force needed for reduction, consider GEA; – closed reduction w/ longitudinal traction, & correction of radial angulation; – … Read more

– See: STSG – Discussion: – full thickness grafts transfer all organs contained in the dermis in addition to some Pacinian corpuscles (when the graft is taken from the palm or sole); – these grafts allow more durable coverage and more sensation than STSG; – donor site: … 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
– 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
– Technique: – Brunner Incision is made extending from distal phalanx of thumb to the MP crease; – digital nerves and vessels are identified (protected by Grayson’s ligament); – dissection procedes down to the oblique and transverse flexor tendon sheaths; – the proximal … Read more
– See: Flexor muscles of the Forearm: – Superficial muscles arise from a common tendon attached to the lateral epicondyle of the humerus, and divide into lateral and medial groups; – Lateral three of these muscles: Brachioradialis Extensor … Read more
– Discussion: – it is essenital to accurately determine the optimal tension to be applied to the motor unit; – use the relaxed natural cascade of the fingers to assist in determining the optimal tension; – most often the tendon graft is sutured to the proximal FDP in the … Read more
– Anatomy: – on volar aspect of finger, FDP passes through FDS to insert on distal phalanx; – both long flexor tendons are tightly enclosed in common tendon sheath which corresponds to zone II; – anatomical proximity explains the development of adhesions between FDS & FDP tendons & digital fibrous sheaths following injury; – excursion … Read more
