The SBi Uni-Elbow[TM] Radio Capitellum System is designed specifically for uni-compartmental arthroplasty for degenerative joint diseases, the correction of functional deformities, revision procedures and treatment of fractures.
In the case of OCD, the loose body is usually located near the capitellum and radial head; for fractures, near the site of injury; for synovial chondromatosis, loose bodies are frequently anterior.
The capitellum contains thick hyaline cartilage anteriorly that articulates with the proximal radius.
While this might be sufficient for fixation of a simple capitellum fracture, the coronal shear fracture requires a more extensile exposure of the anterior humeral articular surface.
3) The radial head fractures are caused by a valgus force on the elbow as the head is driven into the capitellum.
Isolated fractures of the capitellum are rare, accounting for 1% of all fractures about the elbow.
30,31) In the setting of interosseous membrane injury, the Sauve-Kapandji procedure can result in instability of the proximal ulnar stump and significantly increase forces transmitted to the capitellum.
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.
13) It is a focal lesion, usually of the capitellum, which may be due to compressive forces producing arterial insufficiency leading to avascular necrosis.
This was followed last year with the introduction of the SBi UNI-Elbow Radio Capitellum System(TM) as the first commercially available uni- compartmental elbow arthroplasty system.
f) Sites of pathologic fracture: 2 fractures at T11; 1 fracture each at C4, medial femoral condyle, distal humeral metaphysis, humeral capitellum, fifth metatarsal, and second proximal phalanx (hand).
