Sagittal band reconstruction.
Extensor tendon subluxation at the metacarpophalangeal joint occurs only rarely in patients without rheumatoid arthritis. Almost all reported cases involve disruption of the radial sagittal band with ulnar subluxation of the extensor tendon. A technique of sagittal band reconstruction is described that entails weaving a retrograde segment of extensor tendon upon itself after passing it through the deep transverse metacarpal ligament. Twenty-one sagittal band reconstructions were performed in 16 patients. This series included 18 cases of ulnar subluxation secondary to radial sagittal band disruption and 3 cases of radial subluxation secondary to ulnar sagittal band disruption. Using this technique, pain was eliminated in every case and there has been no recurrence of extensor tendon subluxation.
