Post-Burn Hand Contracture / Hand Deformity Correction | Existing website questions

Burn scars can tighten and limit hand function. Release is usually done after scar equilibrium, often three to six months, when tenderness and redness have settled. The surgeon divides scar bands at the point of maximum tension, then covers the defect with a graft or flap. Full-thickness skin grafts are generally preferred over split-thickness grafts because they tend to recontract less. Postoperative splinting, hand therapy and scar care are vital, while bleeding, nerve injury, wound problems or recurrent contracture may require further care. Results depend on scar severity, joint involvement and rehabilitation. Children may need more procedures during growth spurts, and recurrent contractures may require reoperation to achieve satisfactory function. Appropriate acute burn care can limit severity.

After a burn, scar tightening and the hand's position of comfort can pull the wrist and fingers into a clawed posture, especially when the back of the hand is burned. Correction usually means releasing the tightened scar and covering the released area with skin graft or flap, because simply replacing scar does not restore movement. The surgeon must also address tendons, joints, vessels and nerves, since these often limit correction. Full-thickness skin grafts may be preferred over split-thickness grafts for contracture release because they tend to recontract less. The extent of release matters more than the type of cover, and postoperative splinting and therapy help maintain the movement gained.

A first web contracture after a burn may involve scarred skin, fibrous bands and a tightened adductor pollicis muscle, so the thumb can no longer abduct or oppose well. This affects grasping large objects and fine pinch. The web has a surprisingly large surface area once fully released, and severe adduction may need wide release of deep structures, leaving a defect on both sides of the hand. Local tissue may then be inadequate, so graft or flap coverage is considered. Full-thickness skin grafts are often preferred to split-thickness grafts because they tend to recontract less, though recovery depends on burn severity, age and health. Procedures may be staged if necessary.

Post-burn hand contracture release aims for maximum safe correction, but deeper structures such as tendons, muscles, vessels and nerves can limit release and may be at risk if stretched too far. Skin cover is provided after complete or maximum possible correction. The correction achieved at surgery is likely the maximum achieved; postoperative splinting and therapy help maintain gains but rarely increase range beyond what was obtained on the table. In some dorsal releases, temporary axial Kirschner wires are useful to hold position, while in distraction lengthening K wires may be placed in metacarpals and distal phalanges for skeletal traction. Full-thickness skin grafts can help counter contracture recurrence and are preferred when possible.

Post-burn hand contractures can limit function. Surgical release with graft or flap coverage is the primary treatment when splinting, stretching and therapy are insufficient. Waiting for scar maturity, usually 3–6 months, may reduce recurrence, but delaying too long can risk permanent loss of motion. Full-thickness skin grafts may be preferred over split-thickness grafts because they are less prone to recontracture. Recovery depends on burn severity, age and general health; major burns may need many operations, while minor burns can heal in weeks. Early wound closure and rehabilitation can help restore hand function, and stiffness can develop quickly, so regular therapy matters. Postoperative splinting, wound care and hand therapy are vital, and children may need more procedures during growth.

Syndactyly means fingers are joined by scarred skin and deeper tissue. Separation aims to restore independent movement and a normal web space, not just appearance, with realistic goals and careful assessment for each hand. The surgeon must preserve nerves and blood vessels, then cover the new gaps; full-thickness skin grafts are generally preferred over split-thickness grafts for post-burn release because they tend to recontract less. Timing and extent vary: some cases are managed with pressure garments and spacers, while surgery is considered for limited abduction, loss of independent finger movement, persistent skin breakdown, limited extension or inability to wear rings. In children, growth may require further procedures and scar care.

Severe post-burn contractures can make intubation difficult, so anesthesia planning matters as much as the release itself. Older approaches included blind nasal intubation; if that failed, release under local anesthetic infiltration was used, and ketamine was sometimes used, especially in children, before intubation. Laryngeal mask airways and fiberoptic bronchoscopes have made anesthetizing severe contractures safer and simpler. Local anesthesia with epinephrine may also help hemostasis and dissection in some releases. The exact choice depends on contracture extent, scar location, airway assessment and your overall condition. Positioning and airway planning are therefore included before surgery. This is discussed with you before surgery.

Post-burn hand contractures develop when scar and deeper tissues shorten, often after delayed healing or graft contracture. Surgery aims to release the tight scar and restore movement, sometimes using Z-plasty, skin grafting or flap coverage. Full-thickness skin grafts may recontract less than split-thickness grafts, but recurrent contractures can still need further surgery. In children, neglected contractures may still be approached to improve function, yet severe contractures present decades after childhood burns may not be fully correctable. Release is usually considered once scar tenderness and redness settle, often around three to six months, because timely release helps prevent permanent loss of motion. Postoperative splinting, hand therapy and scar care are vital to a successful outcome.

Deep hand burns can heal with scar contraction that limits movement, especially across joints and web spaces. Contracture release with scar excision and graft or flap coverage is the primary treatment. Full-thickness skin grafts are preferred over split-thickness grafts when possible because they tend to recontracture less. Surgery is usually considered after scar equilibrium, often 3–6 months, and may be staged. Preoperative planning includes a complete hand examination of skin quality, previous grafts, web spaces and joint range of motion. Postoperative splinting, hand therapy and scar care are vital, and recurrent contractures may need reoperation. Children may need more procedures during growth spurts, and attention to acute-phase care can limit later contracture.
