External fixation techniques include the use of pins in bone that are held in place through their attachment to an external fixation device. Internal fixation techniques include the use of wire, pins, plates, and screws. These techniques include devices that hold the bone fragments in place either inside the body (internal fixation) or outside the body (external fixation). Below are treatment measures that can help. These fragments must be held in place while the bone heals. If a jammed finger is not severe and there is no reason to suspect a fracture, it can be self-treated at home. Your surgeon may use one of several operative fixation techniques to realign the bone fragments. Surgery may be needed, depending on the location of the fracture and the amount of movement between the broken fragments of bone. During that time, regular X-rays may be needed to ensure that the bone has not slipped out of alignment. The cast may need to be worn for at least 4 to 6 weeks. Physical therapy exercises will be ordered to enhance flexibility, range of motion and strength.If the bone fragments of the fracture have not moved (displaced) very much, or if the break is located in the middle (shaft) of the bone, your surgeon may be able to use a specially designed cast (spica cast) to hold the bone fragments in place. Surgery is followed by rest and plaster cast immobilization for about 4 weeks. Pins or screws are used to align the dislocated bones. A small incision is made at the base of your thumb. Open reduction and internal fixation (ORIF) is the most common surgery to treat Bennett’s fracture. Surgery may be recommended if you do not respond to conservative treatment options.

It may progress to arthritis of the thumb joint. Untreated Bennett’s fracture may cause complications such as continued pain, weakness of the thumb, stiffness or dislocation of the CMC joint. What Happens if Bennet’s Fracture is Left Untreated?
