Dupuytren Disease With a 50-Degree PIP Contracture in a Musician
A 64-year-old retired carpenter, right-hand dominant and an avid classical guitarist, presents with a 40-degree metacarpophalangeal contracture and a 50-degree proximal interphalangeal contracture of the right ring finger. The tabletop test is positive. There is skin pitting over the proximal interphalangeal joint, a palpable cord running from the palm into the digit, and a 6 mm palmar nodule. He had a limited fasciectomy on the contralateral small finger nine years ago with recurrence that he describes as worse than the original. He takes aspirin 81 mg daily and has diet-controlled diabetes with an HbA1c of 7.4 percent. He wants to keep playing and asks about the injection he saw advertised.
1. Compare the available interventions for this specific finger and recommend one, explaining how the joint involved drives the choice.

The proximal interphalangeal contracture drives the decision, because metacarpophalangeal contractures correct readily with almost any technique while proximal interphalangeal contractures do not.
- Observation suits a tabletop-negative palm, not a 50-degree proximal interphalangeal contracture in a player.
- Needle fasciotomy is quick and inexpensive, but it works by tearing rather than removing cord. Metacarpophalangeal correction is good; proximal interphalangeal correction is incomplete and less durable, and recurrence is higher.
- Collagenase is reasonable for a discrete palpable cord with a metacarpophalangeal-dominant contracture. It is less effective at the proximal interphalangeal joint, and the pitting over that joint signals a thin envelope at risk of rupture during manipulation, which would leave an open wound in the digit.
- Limited fasciectomy is the standard here. It allows the neurovascular bundles to be seen and protected, permits excision of the diseased cord, and permits direct treatment of the proximal interphalangeal joint (check-rein and accessory collateral release) when the joint remains tight after cord removal.
- Dermofasciectomy is reserved for recurrent disease, young patients, or skin that cannot be closed without tension.
Recommend limited fasciectomy, plan for a possible full-thickness skin graft, and counsel that a residual 10 to 20 degrees is common and that recurrence at five years is roughly 20 to 30 percent, higher with diabetes and proximal interphalangeal disease.
2. He asks why he should not simply have the injection. How do you answer him?

Answer with the evidence rather than with a defense of surgery:
Collagenase is a legitimate option for a single palpable cord with a metacarpophalangeal-dominant contracture in someone who wants to avoid an operation. It is less reliable for a 50-degree proximal interphalangeal contracture, which is his main problem, and the skin pitting over that joint means the skin is thin and at risk of tearing during the manipulation step. A rupture there converts a closed procedure into an open wound in the finger he uses to play.
With surgery I can see and protect the neurovascular bundles, which matters in a digit with proximal interphalangeal disease and skin involvement, and I can address the joint itself if it stays tight after the cord is excised.
Both routes require hand therapy and splinting, and both have recurrence. The injection trades a smaller procedure now for a lower chance of full correction and a higher chance of needing another treatment.
I would also note his prior recurrence on the other hand. That history is a risk factor for recurrence regardless of technique, and it argues for the approach that gives the most complete initial correction, not the fastest one.
3. How will you manage the skin and the postoperative course, and what will you tell him about returning to the guitar?
Read the worked answer
Skin: use a Bruner or longitudinal incision with Z-plasties over the proximal interphalangeal joint, and never close under tension. With pitting and a 50-degree contracture, a defect is likely after full release; apply a full-thickness graft from the wrist crease or antecubital fossa rather than forcing closure, and be prepared to convert to dermofasciectomy. The cord often envelops the digital nerve and artery, so dissection proceeds under direct vision, loupe magnification, and a tourniquet.
Postoperative course: bulky dressing and elevation; begin active and active-assisted motion at three to five days with a hand therapist; night extension splinting for six to eight weeks, acknowledging that the evidence is weak but the risk is low; wound check at 10 to 14 days. Optimize glycemic control with his physician, since an HbA1c of 7.4 percent is acceptable but not ideal for wound healing.
Counseling: quote the risks of digital nerve injury, skin necrosis, and a complex regional pain syndrome-type flare. For the guitar, he can return to light playing once wounds are healed and motion is stable, typically six to eight weeks, with a graded schedule and acceptance that barre chords requiring full proximal interphalangeal extension may remain difficult. Warn that recurrence is likely over a decade and that surveillance, not a one-time cure, is the realistic expectation.
