From the Guidelines
Yes, there are effective ways to reduce scar tissue in fingers years after tendon repair, though complete elimination may not be possible. The most effective approach is often a combination of treatments. Some key methods include:
- Massage therapy, involving firm pressure applied to the scar for 5-10 minutes, 2-3 times daily using circular motions and cross-friction techniques.
- Silicone gel sheets or ointments (like Mederma or ScarAway) applied daily for at least 12 hours can soften scars when used consistently for 2-3 months.
- Physical therapy focusing on specific exercises to improve finger mobility and break down scar tissue is also beneficial, typically requiring 2-3 sessions weekly for 4-8 weeks.
- For more severe cases, steroid injections (triamcinolone 10-40mg/ml) administered by a healthcare provider every 4-6 weeks may help flatten and soften scars. These treatments work by increasing collagen breakdown, improving collagen alignment, and enhancing blood flow to the area 1. While older scars are more resistant to treatment, persistent efforts over months can still yield improvements in both appearance and function of the affected fingers. It's also important to note that relative rest and avoiding activities that exacerbate the condition can help in the healing process, as suggested by studies on tendon problems 1. However, the most recent and highest quality study 1 provides the most relevant guidance on reducing scar tissue in fingers after tendon repair, emphasizing the role of MRI in evaluating tendon injuries and guiding surgical planning.
From the Research
Effective Ways of Reducing Scar Tissue
- The use of compression, massage, splints, and functional activities can help minimize the formation of scar tissue and restore maximal hand function 2.
- Viscosupplementation with hyaluronic acid has been shown to reduce the formation of scars and granulation tissue after tendon repair, and improve tissue healing 3.
- Early motion and rehabilitation after tendon surgery can help prevent new adhesions from forming and improve mobility 4.
Treatment Options
- Corticosteroid injections can be used to treat chronic tendon disorders, but their effectiveness and safety are not well established 5.
- Tenolysis can be used to treat peritendinous adhesions, and rehabilitation after this procedure should include immediate and extended mobility exercises to maintain mobility and prevent new adhesions 4.
Scar Formation and Healing
- Tendon healing is characterized by the formation of fibrovascular scar tissue, which can create a substantial clinical challenge in the setting of large, chronic tears 6.
- The concept of scarless healing is being studied, with the goal of manipulating the expression of genes and activating mechanisms to promote true tissue regeneration 6.
