A central slip tendon injury means that you have damaged the tendon over the middle part of the top of your finger, so you are not be able to straighten your finger. If the tendon ruptures without harm to the skin, this is called a closed injury. When the tendon and the skin are cut, it is classified as an open injury.
What is a central slip tendon injury? The central slip tendon is the main tendon for straightening the middle joint (‘PIP’) of the finger. It acts as the link between some of the muscles in your forearm and the middle bone of the finger. When these muscles contract, they pull on the central slip, which then pulls your finger straight. This injury occurs by either:
What is a central slip? Arising from the extrinsic extensor tendon and lateral bands, the central slip is a tendinous attachment to the base of the middle phalanx. The transverse retinacular ligament stabilizes the extensor mechanism over the PIP joint and limits any dorso-palmar translation ( 1 ). Central slip disruptions can occur as either open or closed injuries.
Which splints are used in the treatment of central slip tendon injury? Patients who have had a surgical repair of a central slip tendon injury will require different splints [25] [2] : Full finger volar extension splint – worn at all times, except for during exercises Volar slab from distal metacarpophalangeal (MCP) joint to the end of the finger – allowing 30° PIP joint flexion and 20° DIP flexion
What are the slips of the EDC tendon? [3] The Extensor Digitorum Communis (EDC) tendon at each finger splits into three bands or slips. These slips are: the central tendon/slip, which inserts on the base of the middle phalanx; and two lateral bands/slips, which rejoin as the terminal tendon/slip to insert into the base of the distal phalanx.

What is the difference between central slip and uninjured fingers? A) Uninjured fingers show a symmetric inability to straighten the distal interphalangeal joint when the middle interphalangeal joints are flush against each other. B) In a central slip injury, the distal interphalangeal joint is pathologically straightened, which is seen in the left hand in this example. ( Illustration by David Ting)

What causes a central slip injury? Central slip injury is often caused by a joint dislocation or forced flexion of the proximal interphalageal joint (PIP joint). This causes rupture of the central slip, which is part of the extensor tendon that straightens the PIP joint. The tendon can tear away from the bone or pull a small fracture fragment with it. What are the symptoms?

Central slip disruptions can occur as either open or closed injuries.
What is a central slip injury (boutonierre deformity)? WHAT IS A CENTRAL SLIP INJURY (Boutonierre Deformity)? For our fingers to straighten, several tendons need to work together. These tendons run along the side and on the top of the finger. The tendon that runs along the top is called the central slip and attaches to the middle bone of the finger.
