Extero-internal—radial head i)artly cov-ered by ulna 2. Antero-posterior—radial head visible 3. Extero-internal oblique—to isolate radio-humeral articulation Difficulties 1. Various positions not always possible, be-cause of deformity 2. In children do lateral view first, becausepainless 3. Dislocation of radial head may be over-looked in lateral view 4. Where extension not possible, place pointof elbow on plate and focus over it. 182 FOREARM
