Low-Dose Radiation Therapy (LDRT) vs. Other Treatments for Dupuytren’s

Dupuytren’s disease causes bands (“cords”) and nodules in the palm that can pull the fingers into the palm over time. Early disease is often an “active/inflammatory” phase with tender nodules; later disease causes fixed contractures. Because the condition behaves differently by stage, the best treatment depends on when you catch it.
The main options, at a glance
Option | When it’s used | What it does | Recovery | Recurrence/Progression (typical ranges) | Notable risks |
LDRT (high-energy X-rays at low dose) | Early, active nodules/cords (before fixed bend) | Calms inflammatory fibroblast activity to slow or stop progression; may reduce pain and nodule size | No incision; visits over 2 short series | In long-term prospective data, stage progression was 16–22% with RT vs 52% without; best results when started very early; 30 Gy schedule trends best | Mostly mild skin dryness; serious late effects very rare at hand doses/fields; theoretical cancer risk estimated to be very low |
Collagenase injection (CCH/Xiaflex) | Established cord causing a bend (MCP/PIP) | Enzyme weakens cord; next day manipulation straightens finger | Office-based; fast | Systematic review: ~10–31% recurrence at up to 4 yrs; repeat injections can work but with higher minor AEs | Skin tears common (9–25%); rare tendon rupture; swelling/bruising |
Needle Aponeurotomy (percutaneous needle fasciotomy) | Similar to CCH—office release of a bend | Needle divides cord percutaneously | Fastest recovery | ~50–58% recurrence by 3–5 yrs (higher than surgery/CCH) | Skin tears; nerve injury uncommon; recurrence common |
Open Limited Fasciectomy | Moderate–severe contractures, recurrent disease | Surgically removes diseased fascia | OR procedure; weeks of rehab/splinting | ~12–39% recurrence by ~1.5–7 yrs (lower than NA; higher morbidity) | Wound issues, nerve injury (2–5%), CRPS (2–13%) |
Dermofasciectomy + skin graft | Aggressive/recurrent patterns | Removes skin + fascia | OR + graft care | Often lowest recurrence, but more invasive (data vary) | Graft healing issues |
Steroid injections into nodules | Painful early nodules | May soften/shrink nodules; symptom control | Office visit | Improvement possible, but recurrence up to ~50%; does not correct established cords | Fat atrophy, skin discoloration, rare tendon injury |
What exactly is Low-Dose Radiation Therapy (LDRT) and how is it given?
Protocol: Most often 30 Gy total (two series of 5 daily treatments at 3 Gy, separated by ~6–12 weeks).
How it works: Low-dose X-rays damp down the overactive myofibroblasts and pro-fibrotic signals (like TGF-β) that drive nodule/cord growth—essentially “turning down the volume” on the biology that makes Dupuytren’s spread.
Outcomes: does LDRT actually change the course?
In large long-term prospective studies, progression to a worse stage occurred in 52% without treatment, versus 22% after 21 Gy and 16% after 30 Gy.
Symptoms (tenderness/pain) and extension deficit worsened in controls but improved or stabilized after RT.
Toxicity: Mostly mild skin dryness; no severe late effects in major series; the theoretical lifetime cancer risk from a small hand field at these doses is estimated to be very low.
How does LDRT compare to injections and surgery?
If you catch Dupuytren’s early (tender nodules, minimal bend):
Low-Dose Radiation Therapy (LDRT) is the only modality with prospective long-term evidence showing reduced progression versus observation, especially when started early. It’s noninvasive and may delay or prevent the need for later procedures.
Steroid shots can reduce nodule size/pain for some, but skin atrophy/discoloration are common and recurrence is frequent.
If a finger is already bent (established cord):
CCH injections and needle aponeurotomy straighten quickly with minimal downtime. However, recurrence is higher after NA (~50–58% by 3–5 yrs) and 10–31% after CCH at ≤4 yrs.
Limited fasciectomy offers lower recurrence (12–39%) at the cost of surgery, therapy, and a higher complication profile. Dermofasciectomy may reduce recurrence further in aggressive patterns but requires a graft and longer rehab.
Bringing it together:
LDRT is about disease modification in the early phase (slow/stop progression).
CCH/NA/surgery are about straightening once a bend exists; they don’t prevent new cords from forming elsewhere, and recurrence over time is common across all interventional options.
Safety, age, and risk trade-offs
Hand LDRT uses much lower doses and smaller fields than cancer radiotherapy; serious late effects are rare in long-term hand series. Still, many clinicians prefer to reserve LDRT for adults (often >40–50) and avoid it in pregnancy.
For CCH/NA/surgery, the main risks are local: skin tears, nerve injury, stiffness, CRPS, and wound complications (higher with open surgery).
Practical recommendations to discuss with your clinician
Match the treatment to the stage.
Tender, growing nodule with little to no bend? Discuss LDRT early, ideally during the active phase.
Already bent finger? Consider CCH or NA if you want quick recovery, or limited fasciectomy (or dermofasciectomy) if you prioritize lower recurrence and accept surgical recovery.
Be transparent about goals. LDRT aims to delay/avoid progression; CCH/NA/surgery aim to straighten—they solve different problems.
Plan for the long game. Dupuytren’s is a biology-driven disease; recurrence can happen after any treatment, so follow-up and hand therapy matter
Bottom line
LDRT is most compelling before a fixed bend develops—to slow or halt progression with minimal downtime.
CCH/NA/surgery are best once a contracture is present—great for straightening, each with different trade-offs in recurrence, invasiveness, and recovery.
The best plan is personalized: stage, digit involved, risk tolerance, recovery needs, and whether your priority is preventing progression now or straightening an existing bend.
