How do you treat a sagittal band injury?
Conclusion: Qualitative synthesis of available literature suggests that acute sagittal band injuries can be successfully treated by splinting the injured digit in neutral or hyperextension. Patients with chronic injuries or those failing nonoperative management may benefit from surgical exploration.
What is sagittal band tear?
Sagittal band rupture is a cause of a bent finger. The sagittal band is part of the extensor mechanism in the finger. It allows extension (straightening) at the knuckle of the finger (metacarpal phalangeal joint, MP joint) of the finger. The bend, or flexion, is located at the knuckle of the finger (see photo).
How long does it take for sagittal band to heal?
It takes about 8-10 weeks for the sagittal band to recover full strength.
How do you test for a sagittal band rupture?
A classic test to reveal a sagittal band rupture is to passively place the digits into extension and actively hold them in place. If able to maintain full extension when passively placed, a long extensor injury or rupture is unlikely.
Can a sagittal band heal on its own?
Can I treat a torn sagittal band at home? If the sagittal band is not fully torn, then it may be possible for the condition to be treated at home with conservative methods, particularly splinting, anti-inflammatory medications, icing, rest, and possible pain relief.
Is the sagittal band a tendon?
The sagittal band of the finger is an aponeurosis-like structure surrounding the metacarpophalangeal joint. Sagittal band rupture causes extensor tendon dislocation from the dorsal side of the metacarpophalangeal joint. The thumb has two extensor tendons: extensor pollicis longus and extensor pollicis brevis tendons.
Can a sagittal band rupture heal on its own?
Is sagittal band an extensor tendon?
At the level of the MCP joint, the extensor digitorum tendon is joined by the sagittal bands, one of the main components of the extensor hood. The sagittal bands attach volarly to the palmar plate of the MCP joint and dorsally to the extensor tendon.
Will jersey finger heal on its own?
If the injury involves a full tendon rupture or a rupture with a bone chip attached, the finger will not heal on its own. Surgery will be required to repair soft-tissue damage and restore your finger’s ability to bend or move.
