Combined shear fractures of the trochlea and
capitellum associated with the anterior fracture-dislocation of the elbow.
Examination revealed a swollen and tender elbow, with plain x-ray confirming a subchondral bone disorder (osteochondral defect) of the
capitellum.
This year, we enjoyed substantial contributions from the Division of Sports Medicine, with six graduates reviewing topics, including anterior cruciate ligament reconstruction, bone marrow lesions about the knee, osteochondritis dissecans of the
capitellum, and management of tendinous injuries of the gluteus medius and pectoralis major.
The ligament suffers no injury and is interposed between the dislocated radial head and the
capitellum [8].
Panner disease is an osteonchondrosis that affects the
capitellum in throwing athletes between the ages of 7 and 12 years, who present with pain and impaired extension of the dominant arm.
The insertion site was selected so that the pin would traverse the lateral portion of the ossified
capitellum cross the physis proceed up the lateral column and always engaged the opposite medial cortex proximally.
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.
The
capitellum and trochlea are distorted due to the angle of the CR.
X-rays may show an irregular lucency of the
capitellum.
