“…Operative and nonoperative management of symptomatic ulnar subluxation after sagittal band injury in nonrheumatoid patients has been described in the literature [8, 10–12]. Watson et al describe a successful technique using a distal extensor tendon slip on the side of the affected sagittal band to aid reconstruction, by looping it through the transverse metacarpal ligament.…”

Background. Radial subluxation of the extensor communis tendons at the metacarpophalangeal (MCP) joints is a rarely reportedvinjury. These injuries have proved difficult to reproduce in cadaveric studies and have a low biomechanical likelihood of occurrence due to the ulnar direction of pull of the extensor communis tendons. It has been suggested that the juncturae tendinum may have a stabilising role, preventing radial subluxation after ulnar sagittal band rupture; however this has not been established. Methods. 40 cadaveric digits were dissected to reveal the extensor mechanism around the MCP joints. The ulnar sagittal bands were released and then the juncturae tendinum divided, in stages, before observing for radial subluxation or dislocation during finger flexion. Results. Radial subluxation of the extensor tendon was observed in only one digit after complete ulnar sagisttal band release. When all the fingers were flexed, after the juncturae tendinorum were divided, four additional tendons subluxed radially and a fifth tendon dislocated in this direction. When the digits were then flexed individually, there were eight unstable tendons in total. Conclusions. The juncturae tendinum appear to have a role in stabilising the extensor communis tendons at the MCP joints and preventing radial subluxation after ulnar sagittal band rupture.

“…SB injury is a rare clinical condition, most commonly seen in boxers as a result of trauma. Rheumatoid arthritis is the primary atraumatic cause of SB rupture 3. The physical examination reveals pain on palpation, joint movement difficulties with finger extension–flexion and medial–lateral subluxation of the extensor tendon on the MCP joint (figures 3 and 4).…”
