Filter by:Research is instrumental for improving medical care and the patient experience. Finding new surgical techniques can create better outcomes and minimize recovery time and complications for patients. Some patients undergoing trigger finger surgery with a pre-existing Dupuytren's cord may develop a thickened surgical scar after surgery, which can cause discomfort, difficulty with moving or using, and other complications in the affected finger(s) or hand. The investigator is investigating a surgical technique to minimize these potential complications and scarring after surgery. Subjects are being asked to take part in this research study because they have been diagnosed with trigger finger and pretendinous Dupuytren's cord and have decided to undergo surgery rather than try medical treatment.
Dupuytren's disease is a non-curative, progressive disorder leading to function-impairing deformities of the hand. Although numerous treatments exist, the most common and widely accepted therapy is removal of diseased fascia. Surgery is limited by prolonged recovery time, and many patients require multiple surgeries throughout their life as the disease progresses, with repeat surgeries increasing the risk of complications. Long recovery times and need for repeat surgeries has renewed interest in minimally invasive treatments for Dupuytren's disease. Percutaneous needle aponeurotomy (PNA) allows for rapid improvement in finger extension with minimal recovery time. The FDA approved collagenase clostridium histolyticum injection for Dupuytren's disease in 2010, which also allows for rapid increase in finger extension, also with minimal recovery time. Currently there is only one small study comparing PNA and collagenase injection (CI) that suggests similar outcomes in both treatments. Both treatments are minimally invasive, requiring minimal time off work and post-procedure pain. The main barrier to widespread adoption of CI is cost, particularly in patients with multiple areas of disease requiring treatment. The project proposed will compare these two methods for treating Dupuytren's disease. Approximately 334 participants will be recruited from patients referred for treatment to hand surgeons trained in CI and PNA at two Calgary, AB hospitals. Need for treatment will be determined in the usual fashion, and the option for entry into the study will be proposed to patients meeting inclusion/exclusion criteria. Participants will be randomized into either the PNA or CI treatment group. The surgeon will not be blinded to the procedure group; however, the therapist measuring outcomes will be, and the study participants will need to not divulge to the therapists which group they are in. Both procedures are performed under local freezing, and range from 5-20minutes. PNA involves the surgeon freezing the skin over the Dupuytren's cord, then using a small gauge needle inserted under the skin to cut the cord. This is repeated up the length of the cord to weaken it, allowing the surgeon to extend the finger and rupture the cord. CI involves the injection of collagenase (Xiaflex®), directly into the Dupuytren's cord. The patient then returns to see the surgeon within one week, has freezing placed in the hand, and the affected digit is extended to rupture the already weakened cord. The patient will be required to present to the hand therapist team for measurements of joint angles before and after the assigned treatment is performed. In order to measure treatment efficacy, study participants will be required to return for measurements of treated joints every 6 months. Lastly, participants will need to inform the performing surgeon or therapist, at follow-up visits of any complications they experience.
The purpose of this study is to investigate whether percutaneous needle fasciotomy is as effective for treating Dupuytrens contracture as Xiapex. Immidiate treatment effect is to be investigated, as iskontracture size after 5 years. Contracture size after one and three years, and subjective hand function is also to be investigated.
This study will evaluate short-term pain and function associated with percutaneous needle aponeurotomy (PNA) and injections of the enzyme collagenase clostridium histolyticum in patients with Dupuytren's disease. Scores on outcome measures will be compared between groups to determine whether treatments differ in terms of hand function and pain during the early post-treatment period.
Dupuytren's disease is a progressive disease due to unknown causal agents or genetics. Dupuytren's disease contains nodules and cords in the fascia as the epicenter of disease progression. Nodules contain whorls of collagen bundles and are densely packed with contractile fibroblasts and myofibroblasts. These highly contractile cells are linked to the fascia matrix through transmembrane integrin receptors. The cytoplasmic tail domains of the alpha beta integrin receptors provide a structural link between extracellular matrix and the actomyosin cytoskeleton. Complications of surgical partial or total aponeurectomy in Dupuytren's disease are reported in up to 10% of cases . Often, surgical complications lead to compromised flexion limiting grasping function of the involved hand . A recent 20-year-review of the literature included 41 clinical trials with complication rates reported from 3.6%to 39.1% . 16% major complications occurred with 3% digital nerve injuries, digital artery injuries in 2%, infections in 2%, and complex regional pain syndrome in 6%. Besides selective or total aponeurectomy, soft-tissue distraction has been suggested using either pneumatic devices or external fixateur . Non-invasive options include percutaneous fasciotomy or collagenase injection. The latter has been tested in a randomized-controlled trial published in the New England Journal of Medicine with 308 patients enrolled (NCT00528606) . Collagenase clostridium histolyticum significantly reduced contractures and improved the range of motion in joints affected by advanced Dupuytren's disease. In the long-term the cords at the level of the proximal interphalangeal joint appear to more recurrent than at the metacarpophalangeal joint after collagenase injection with an eight year follow-up . In early stage Dupuytren's contracture, radiotherapy has been suggested to limit disease progression. A cohort study of 135 patients with 208 hands involved received orthovoltage radiotherapy with a total dose of 30Gray separated by a six to eight week interval . After a follow-up of 13 years nodules and cords remained stable in 59%, improved in 10% and progressed in 31%. Beside Dupuytren's disease, there are a number of further less common fibromatosis, such as knuckle pads, M. Ledderhose , of the plantar fascia and peyronie disease at the penis. The latter has been treated by extracorporeal shockwave therapy. A randomized-controlled trial using 2000 focused shock waves reduced pain significantly and improved erectile function and quality of life . About half of the patients in one series of 44 patients had a significant reduction in angulation following shockwave therapy .
