Carpal Tunnel Syndrome (CTS) results from increased pressure on the median nerve as it passes through a narrow passageway in the wrist, causing numbness, tingling, and weakness in the hand and fingers. This compression occurs beneath the transverse carpal ligament, a thick band of tissue spanning the carpal bones. Carpal tunnel release surgery cuts this ligament, enlarging the tunnel and relieving pressure on the median nerve. Understanding the stages of healing is important for managing expectations and restoring hand function.
Immediate Post-Operative Care
The first 48 to 72 hours following carpal tunnel release focus on managing pain, controlling swelling, and protecting the surgical site. A bulky dressing or splint is applied immediately to immobilize and protect the incision. Patients must keep the dressing clean and dry to prevent infection. Keeping the hand elevated above the heart level, such as by using pillows while resting, helps minimize swelling and discomfort.
Pain management uses a combination of prescription and over-the-counter medications, as directed by the surgeon. Applying wrapped ice packs to the area for short intervals also helps reduce pain and swelling. Even while wearing the immobilization splint, gently wiggling the fingers is encouraged from the first day to prevent stiffness and promote circulation.
Mild to moderate discomfort is expected, but patients must monitor the surgical site for signs of complications. These signs should be reported promptly:
- Excessive bleeding that soaks through the bandage.
- Persistent fever.
- Thick, discolored, or foul-smelling discharge from the incision.
- Uncontrolled pain not relieved by prescribed medication.
The splint or dressing is typically worn until the first post-operative appointment, often within the first two weeks.
The Recovery Timeline and Milestones
The progression of healing involves several milestones, starting with the removal of sutures or staples, typically 10 to 14 days after surgery. Until the incision is fully closed, showering requires careful protection of the surgical site using a waterproof cover. Once sutures are removed, the patient can wash the hand normally with soap and water, but soaking the hand in a bath or pool is restricted until the wound is completely healed.
Resuming activities like driving is generally possible once the patient stops taking narcotic pain medication and regains sufficient strength and reaction time. Most patients return to driving between one and three weeks post-operatively. This timeline depends significantly on whether the dominant hand was operated on.
Restrictions on lifting and gripping prevent strain on the healing ligament and incision. Surgeons advise against lifting anything heavier than a small book or coffee mug for the first two weeks. Restrictions on heavy lifting (exceeding five to ten pounds) and strenuous gripping typically extend for four to six weeks. Although immediate symptoms like numbness and tingling may resolve quickly, the recovery of full nerve sensation often continues gradually for several months.
Rehabilitation and Restoring Hand Function
Active engagement in rehabilitation is important for the best functional outcome, often beginning with gentle motion exercises soon after the procedure. Occupational or physical therapy is frequently prescribed to guide the patient in regaining strength, flexibility, and mobility. Early therapy focuses on gentle range-of-motion exercises for the fingers and wrist to counteract stiffness and promote tendon movement.
Specific exercises, such as tendon gliding, involve moving the fingers through defined positions. This encourages the median nerve and tendons to slide smoothly within the enlarged carpal tunnel, preventing restrictive scar tissue formation around the nerve. These exercises are typically performed multiple times daily, even before formal therapy begins, to maintain circulation and flexibility.
Scar management begins once the incision has fully closed, as the surgical site often remains sensitive. Scar massage is introduced to desensitize the area and soften developing scar tissue. Using a non-perfumed cream, the patient firmly massages the scar several times a day to break down and remodel collagen fibers. Strength-building exercises, such as gripping a soft ball, are intentionally delayed until initial wound healing and range-of-motion goals are met, usually around four to six weeks post-surgery.
Long-Term Expectations and Outcomes
The long-term prognosis following carpal tunnel release surgery is positive, with clinical success rates ranging from 75% to over 90%. Patients typically experience significant relief from preoperative symptoms like night pain, numbness, and tingling. Complete functional recovery, including the full return of hand strength, can take up to several months, as nerve regeneration is a slow biological process.
The surgical scar will mature over time, initially appearing raised and reddish before gradually fading and softening over six months to a year. A potential outcome is pillar pain, which is discomfort localized to the base of the palm on either side of the incision. This pain is common in early recovery, affecting up to a third of patients, but usually resolves within six months.
Some individuals may experience persistent or recurrent symptoms due to incomplete ligament release, excessive scar formation, or pre-existing severe nerve damage. The risk of true recurrence, where symptoms return after an initial symptom-free period, is reported to be between 3% and 20%. For the majority of patients, the surgery provides a lasting solution, significantly improving hand function and quality of life.
