Unicameral Bone Cyst Repair

Unicameral Bone Cyst Repair

A unicameral bone cyst is described as a fluid-filled cyst centrally located in the bone with cortical thinning. These cysts are usually asymptomatic unless fracture occurs. Following fracture healing, the cysts do not typically resolve on their own until possibly later with skeletal maturity. Treatment is necessary for larger cysts and in weight bearing bones to decrease risk of fracture, permanent deformity, or decreased function. This condition does have a high recurrence rate but typically resolves when the patient has reached skeletal maturity.

Some unicameral bone cysts can be repaired while others cannot, depending on the size, location, age, etc. of the lesion. In most, Dr. Chudik evaluates the cyst through a limited incision. Dr Chudik will then drain the fluid from the cyst and scrape out the associated lining to remove the cyst in its entirety. The space is then filled with bone graft. In some cases, a plate or screws are also used to stabilize the healing bone to minimize the risk for fracture. Dr. Chudik will discuss various options with you and help determine the best treatment for you.

Postoperatively, you will be in a sling for up to six weeks to rest the bone and allow recovery and in physical therapy to restore motion and strength for up to four to six months. You may return to sedentary work in less than one week and return to gentle, daily activities about six to eight weeks after surgery Return to sports and more vigorous activities at the four to six months after surgery if the bone has healed.
