Feldman reported two cases of excision of a Type II (Kocher-Lorenz) capitellum fracture which blocked motion.
(2) The pathognomonic lesion of this fracture is extension beyond the capitellum into the trochlear ridge, giving rise to both of the double arcs seen on the lateral radiographs of the elbow (see Fig.
Simulated capitellum fractures were created by osteotomies in the coronal plane at the posterior edge of the articular surface and in the sagittal plane at the lateral edge of the trochlea.

L'examen a revele un coude enfle et douloureux, une radiographie simple confirmant un trouble de I'os sous-chondral (anomalie osteo-cartilagineuse) du capitellum de l'humerus.
In contrast, with homozygous [Ubx.sup.CPTI000601] halteres, a few wing-type bristles (2.4 [+ or -] 1.2 bristles; 25 halteres) were observed on the haltere capitellum (Figure 6(d)).
Pain anywhere in the arc of motion suggests a UCL injury; pain elicited at 45[degrees] of flexion suggests osteochondrosis of the humeral capitellum, while pain closer to frill extension suggests osteochondrosis of the trochlea.
(13) It is a focal lesion, usually of the capitellum, which may be due to compressive forces producing arterial insufficiency leading to avascular necrosis.
Any associated damage to the capitellum was noted before internal fixation.
(2,5) Large valgus loads with rapid elbow extension produce tensile stresses on medial compartment restraints (ulnar collateral ligament, flexor-pronator mass and ulnar nerve) and shear stress in the posterior compartment (posteromedial tip of the olecranon, trochlea, olecranon fossa) and compression stresses laterally (radial head, capitellum).
The capitellum and trochlea are distorted due to the angle of the CR.
X-rays may show an irregular lucency of the capitellum. Sometimes loose bodies within the joint.
