– Congenital Synostosis: – discussion: – occurs due to a defect in longitudinal segmentation at the 7th week of development; – autosomal dominant inheritance in some cases but often occurs sporatically; – bilateral in 60% (most common in … Read more
– See: Radiology of Pediatric Elbow – Discussion: – precise AP & Lateral projections are required to evaluate normal anatomic relationships; – there should be no rotation to the forearm; – AP View: – medial and lateral epicondyles and humeral-ulnar/radial articulation; – carrying angle; … Read more
– See: Pediatric Elbow Injuries – Ossification Centers of the Elbow: – C apetellum (appears age 1-2) – R adial Head (appears age 2-4) – I nteranal epicondyle (appears age 4-6) – T rochlea (appears age 8-11) – O lecranon (9-11 years) … Read more
– See: Radiology of the Elbow – Discussion: – note that accurate AP and Lateral views are essential to judge the reduction; – slightly oblique views can lead to acceptance of malreduction; – AP View: – comparison films are usually required to judge amount of relative varus; … Read more
– Anatomy of Olecranon: – Radiology: – insist on a true lateral X-ray of the elbow joint to evaluate: – extent of frx & displacement: – non comminuted = displacement of less than 2 mm; … Read more

– Discussion: – may occur from frx (Galeazzi fracture or Colles frx), from radial head frx (as a part of an Essex Lopresti injury) or as an islated injury; – injury to the TFCC is a necessary part of this injury; – dorsal subluxation: … Read more
– See: – Posterior Interosseous Nerve Syndrome : – Radial Nerve Palsy Associated w/ Humeral Shaft Frx: – Radial Nerve Block – Tendon Transfers for Radial Nerve Palsy: – Anatomy: – three posterior divsions of brachial plexus form posterior cord: (C5 , C6 , C7, C8, T1) – radial nerve (C5, C6, C7 , C8 … Read more
– Discussion: – indicated for comminuted radial head frx which occur w/ concomitant MCL injury, dislocation, or RU joint disruption (Essex Lopresti Fracture); – will serve as spacer & will prevents proximal migration of radius; – w/ RU joint disruption, radial head spacer alone does not restore satisfactory axial stability w/o pinning the distal radioulnar … Read more
