Fracture of humerus
Humerus is broader, stronger towards the proximal extremity from the mid shaft – fractures are usually found towards the distal part of the shaft

Radial Fracture The radius is formed proximally by the oval and concave
radial head, which articulates with the humeral capitullum. The metaphyseal area tapers slightly to become the flattened radial diaphysis. The diaphysis is of uniform shape, flattened cranial-caudally, and curves slightly as it moves from a lateral position at the elbow to a medial position at the carpus. Distally the metaphysis enlarges and enters the epiphysis. The distal epiphysis has a concave articular surface that sits upon the radial carpal bone. A medial pointed prominence, the styloid process serves as proximal attachment of the medial collateral ligament.
The medullary canal of the radius is usually uniform in size and much wider medial-laterally than cranialcaudally.

Three forms exist:
• dorsal patellar luxation or fixation in adults;
sporadic incidence -Temporary or permanent fixation of patella on upper part of medial femoral trochlear ridge.
• lateral patellar luxation; congenital, uncommon Complete or incomplete lateral displacement of patella.
• medial patellar luxation; congenital, rarelimb flexed with patella freely moveable
