Scar tissue is a thick, fibrous material composed primarily of collagen that the body produces to replace skin damaged by injury, surgery, or burns. When this tissue forms on the fingers, it severely restricts the hand’s natural mechanics, leading to stiffness, chronic pain, and loss of fine motor dexterity. Scar adhesion disrupts the smooth gliding of tissue layers, making it difficult to fully bend or straighten the digits. Understanding scar remodeling is the first step in treating the tissue.
Treating Scar Tissue Based on Its Age
The stage of healing determines how effectively scar tissue can be addressed through non-invasive means. For the first few weeks, the wound is in a proliferative phase, where the body rapidly deposits collagen to close the defect. The remodeling or maturation phase, which typically begins around six weeks and can last up to 18 months, is the crucial window for intervention.
During this stage, the collagen fibers are disorganized and pliable, making them susceptible to physical manipulation. The goal of early treatment is to influence the alignment of these collagen fibers, encouraging them to lie parallel to the natural tension lines of the skin rather than forming rigid, cross-linked bundles. Scars older than one to two years are considered mature; their collagen is stable, highly cross-linked, and far less responsive to massage and topical treatments.
Self-Directed Massage Protocols
Manual therapy is the most direct way to mechanically disrupt the dense collagen fibers and improve tissue mobility. Before starting, the scar must be fully healed, with no open areas, scabs, or signs of infection. The massage should be performed for five to ten minutes, multiple times a day, to provide sustained mechanical input.
One effective technique is deep friction massage, where firm pressure is applied with a fingertip and moved perpendicular to the scar line. This cross-fiber motion helps to physically separate collagen bundles that have adhered to underlying structures. Another method is skin rolling, which involves gently pinching the skin and scar tissue between the thumb and forefinger and lifting it away from the deeper tendons and bone. Circular massage motions, applied with firm pressure, also help to mobilize and soften the tissue, ensuring the scar does not become tethered to the layers beneath it.
Topical Aids and Compression
Supportive external materials enhance the effects of manual massage by optimizing the scar’s environment for remodeling. Silicone is a first-line non-invasive therapy for managing raised, hypertrophic scars. The primary mechanism of silicone is its occlusive effect, which hydrates the outermost layer of the skin, the stratum corneum. This hydration prevents the skin from losing water, signaling to underlying cells to reduce the production of excessive collagen fibers.
Silicone sheets are useful, as they can be cut to fit the contoured surfaces and worn for up to 24 hours a day for several months. Applying an unscented moisturizer or natural oil before massage improves the skin’s elasticity and reduces friction, allowing for deeper, more comfortable manipulation. Compression, often achieved using specialized wraps or tubular bandages, can help flatten a raised scar and manage residual swelling.
Medical Interventions for Stubborn Scars
When self-care techniques fail to improve a scar that is thick, painful, or significantly limiting finger movement, professional medical intervention becomes necessary. A certified hand therapist or occupational therapist can provide specialized techniques, such as Instrument-Assisted Soft Tissue Mobilization, and guide the patient through a regimen of range-of-motion and stretching exercises. These professionals prevent the formation of contractures, which are severe shortenings of the soft tissue that permanently limit joint movement.
For scars that remain raised or red, such as hypertrophic scars or keloids, a physician may recommend corticosteroid injections. The anti-inflammatory properties of the steroids reduce the cell activity that causes excessive collagen production, leading to a flatter, softer scar. For severe contractures that prevent full finger extension, surgical scar revision may be required, often utilizing a technique like Z-plasty to lengthen the scar line and release the mechanical tension restricting the joint.
