Main Menu Home Page -------------------------------------------------------------------------------- Essex Lopresti Fracture: -------------------------------------------------------------------------------- - Discussion: - radial head frx plus dislocation of distal RU joint & interosseous membrane disruption; - mechanism: fall from height; - in this type of frx, radius will also migrate proximally if radial head is excised; - if injury is not found when it is acute, pt may develop severe wrist pain from radial migration and subluxation, of upto 5-6 mm; - there may be loss of forearm pronation, supination, and extension; - late reconstruction( > 4 weeks) of radial instability is poor; - Exam: - distal radio-ulnar joint tenderness is most sensitive test to diagnose injury; - Radiographs: - lateral view of pronated wrist may show ulna to be dorsally subluxated; - Management: - full supination of the forearm usually results in reduction of RU joint; - in order to maintain inadequate radial length & RU joint reduction, consider pinning of RU joint for 6 weeks to allow for anatomic healing of interosseous membrane; - avoid excision: - excision of radial head will result in proximal migration of radius, along w/ severe wrist pain (ulnacarpal impingement) as well as elbow pain; - radial head implants: ---------------------------------------- Radial head fractures and their effect on the distal radioulnar joint.

Posted At 16:42:57 05/07/2001 I am a 20yr old app. Plumber I had a fall from a roof 6 weeks ago and fractured my raidial head and had to get it replaced by a titainium prothesis. How good are these and what are the long term effects yours faithfully Eugene Skinner |
