The concave surface of the radial head matches the convex capitellum and provides stability to the lateral aspect of the elbow joint.
The average distance from the fracture to the radial head articular surface was 72 mm (range: 34 mm to 132 mm) and 41 mm (range: 3 mm to 100 mm) from the bicipital tuberosity.
The topics include diagnostic arthroscopy and loose body removal, plica synovialis of the elbow, arthroscopic radial head resection and open radial head replacement, arthroscopic and open treatment of the throwing elbow: the Docking technique, open medial ulnar collateral ligament repair, the rehabilitation of the overhead athlete's elbow, wrist arthroscopy: triangular fibrocartilage debridement and arthroscopically assisted ulnar shortening, the arthroscopic treatment of scapholunate instability and indications and techniques for the arthroscopic management of scapholunate injuries, and endoscopic carpal tunnel release: the Chow technique.
The isolated dislocation of the radial head is an uncommon injury; it usually presents itself as part of the Monteggia fracture.
MRI may provide added value due to the association of radial head fracture, capitellar fracture and ulnar collateral ligament rupture with triceps injuries (Figure 5).
Most physicians can recall the impressive x-ray of the rickets rosary or the flared radial head seen in medical school.
If the radial head was significantly damaged and determined at this point to be a block to extension then it was excised.
Simple extra-articular fractures are stabilized by tension band wires and two pins (neutralise rotational and shearing forces) placed parallel to each other and directed distally and slightly cranially to penetrate the cranial cortex of proximal ulnar shaft just distal to the radial head.
The MRI indicated hyperintense, demarcated fluid around the radial head, neck, and distal humerus (Figure 3).
Dislocation of the radial head is suggested if the radiocapitellar line (drawn through the center of the radial head and neck) does not transect the midcapitellum on a lateral view.
