Pieces of cord and fascia of approximately one centimeter are excised. The cords are placed under maximum tension while they are cut. A scalpel is used to separate the tissues. The surgeon keeps removing small parts until the finger can fully extend. The person is encouraged to start moving his or her hand the day after surgery. They wear an extension splint for two to three weeks, except during physical therapy.The same procedure is used in the segmental fasciectomy with cellulose implant. After the excision and a careful hemostasis, the cellulose implant is placed in a single layer in between the remaining parts of the cord.After surgery people wear a light pressure dressing for four days, followed by an extension splint. The splint is worn continuously during nighttime for eight weeks. During the first weeks after surgery the splint may be worn during daytime. Less invasive treatments
Studies have been conducted for percutaneous release, extensive percutaneous aponeurotomy with lipografting and collagenase. These treatments show promise. Percutaneous needle fasciotomy
Needle aponeurotomy is a minimally-invasive technique where the cords are weakened through the insertion and manipulation of a small needle. The cord is sectioned at as many levels as possible in the palm and fingers, depending on the location and extent of the disease, using a 25-gauge needle mounted on a 10 ml syringe. Once weakened, the offending cords can be snapped by putting tension on the finger(s) and pulling the finger(s) straight.
Because not all the diseased tissue is visible macroscopically, complete excision is uncertain.A 20-year review of surgical complications associated with fasciectomy showed that major complications occurred in 15.7% of cases, including digital nerve injury (3.4%), digital artery injury (2%), infection (2.4%), hematoma (2.1%), and complex regional pain syndrome (5.5%), in addition to minor complications including painful flare reactions in 9.9% of cases and wound healing complications in 22.9% of cases. After the tissue is removed the incision is closed. In the case of a shortage of skin, the transverse part of the zig-zag incision is left open. Stitches are removed 10 days after surgery.After surgery, the hand is wrapped in a light compressive bandage for one week. Flexion and extension of the fingers can start as soon as the anaesthesia has resolved. It is common to experience tingling within the first week after surgery. Hand therapy is often recommended. Approximately 6 weeks after surgery the patient is able completely to use the hand.The average recurrence rate is 39% after a fasciectomy after a median interval of about 4 years. Wide-awake fasciectomy
Limited/selective fasciectomy under local anesthesia (LA) with epinephrine but no tourniquet is possible. In 2005, Denkler described the technique. Dermofasciectomy
Dermofasciectomy is a surgical procedure that may be used when:

The skin is clinically involved (pits, tethering, deficiency, etc.) The risk of recurrence is high and the skin appears uninvolved (subclinical skin involvement occurs in ~50% of cases)
Recurrent disease.
