<prompt> Growth disturbance, nonunion, elbow instability late ulnar nerve palsy is commonly seen inFracture supracondylar humerusFracture medial condyleFracture lateral condyleFracture head radius  <response>: C i.e. Fracture lateral condyle Milch Classification of Fracture Lateral Condyle Humerus Mitch type I Salter Harris type IV - Less common type - Fracture running through the secondary ossification centre of capitullum and entering the joint lateral to capitulotrochlear groove Cause growth defectQ Mitch type II Salter Harris type II ? IV ? - Commonest - Fracture staing in metaphysis and running along the physis of lateral condyle into trochlear i.e. fracture extends medial to capitulotrochlear groove. - Make ulnar - humeral elbow joint unstableQ. If the lateral condyle is left capsized nonunion is inevitableQ : with growth elbow becomes increasingly valgus and tardy ulnar nerve palsyQ is then likely to develop.
