Surgery to release the cubital tunnel is an outpatient procedure meaning patients go home the same day as surgery. Light use of the arm and hand is often permitted immediately after surgery. An elbow or wrist splint or sling may be used to rest the arm.
Sutures are often absorbable and a follow-up appointment is usually scheduled between one to two weeks after surgery to ensure the wound is healing appropriately. Therapy may be recommended at this point to begin gentle range of motion and strengthening exercises. Once the incision is healed activities can be gradually advanced as tolerated.
If you had constant numbness in the fingers before surgery it can take months for that to recover. If you had lost muscle in the hand that often does not fully recover but should not continue to worsen.
It is possible but uncommon for cubital tunnel symptoms to come back after surgery.
