Re: Нестабильность локтевого сустава

This is a classical series of events. It is unlikely to be the MCL (MUCL) that is damaged. It is more likely to be the LUCL (lateral ulnar collateral ligament), with the elbow pivoting on the radial head causing a subluxation of the humero-ulnar articulation.
Exmination under anaesthesia using image intensifier will help as will an MRI scan. I would repair the LUCL (+/- the MUCL) using the global posterior approach (described by Greg Bain and Stuart Patterson in CORR 2001) and
protect and mobilise the elbow in a Compass Hinge type Ilizarov (or an Ilizarov fixator with a hinge at the elbow). I prefer not to use the
uniplanar Morrey Dynamic Joint Distractor, Mark 2 or Mark 1 (very bad with the distraction pin going through the centre of rotation of the elbow and therefore being intr-articular) or the EBI.
Leaving the elbow in a cast will not achive anything, except making the elbow stiff. There is only one thing worse than a stiff elbow - a stiff unstable elbow. If th patient is averse to surgery, and if the elbow is stable in forearm pronation, try a hinged elbow brace with the forearm locked in pronation, though this is likely to fail in face of this gross instability.
Please let us know the results of your treatment.
