The morphology of the pretendinous cord in Dupuytren's disease is poorly described in vivo and especially with respect to recurrence after treatment. This prospective study was designed to describe the morphology of Dupuytren's cords by ultrasound and to identify possible correlation between the ultrasonographic characteristics of these cords and the clinical outcomes two years after treatment. Thirty-nine patients with a contracture of at least 20° in the metacarpophalangeal (MCP) joint, who were scheduled for local treatment by either injectable collagenase clostridium histolyticum (CCH) or percutaneous needle fasciotomy (PNF), were examined by ultrasound...

Fibrosis is a common lesion in different pathologic diseases and defined by the excessive accumulation of collagen. Different approaches have been used to treat different conditions characterized by fibrosis. The FDA and EMA approved the use of collagenase to treat palmar fibromatosis (Dupuytren's contracture). The EMA approved additionally its use in severe Peyronie's disease, but it has been used off label in other conditions.[1,2] The approved treatment includes up to three (in palmar fibromatosis) or up to eight (in penile fibromatosis) injections followed by finger extension or penile modeling procedures, typically causing severe pain...

INTRODUCTION: The purpose of this study was to explore if there was a correlation between joint level and degree of contracture on the one hand and the risk of skin tear in Dupuytren's disease (DD) on the other, when treated with collagenase from Clostridium histolyticum. No trial or study has explored the risk of skin tear as primary outcome in a population that has not been treated for DD before. METHODS: A retrospective study of prospectively collected data was performed on patients with DD treated with collagenase from 1 August 2012 to 1 April 2014...

The anatomy of the cords that form in Dupuytren's disease is complicated and a spiral cord is the most challenging variant to address. It displaces the neurovascular bundle toward or beyond the midline and closer to the skin. This article illustrates the surface anatomy of the neurovascular spiral to help surgeons identify this zone of danger that the authors term "the serpentine zone." Careful dissection in this zone will help avoid iatrogenic digital neurovascular injury.

Procedural pain is one of the most common adverse effects reported by patients with Dupuytren disease (DD) treated with collagenase clostridium histolyticum (CCH). The aim of this study was to assess the effectiveness of wrist block before CCH injection in reducing procedural pain and to analyze its impact on adverse effects. We performed a prospective, single-center study in which we compared two groups of patients in a consecutive cohort. In the first group (NO-BLOCK), wrist block was only performed before finger extension, whereas in the second group (BLOCK), it was performed before CCH injection and finger extension...

Mechanical properties of myofibroblasts play a key role in Dupuytren's disease. Here, we used atomic force microscopy to measure the viscoelastic properties of 3 different types of human primary fibroblasts derived from a same patient: normal and scar dermal fibroblasts and palmar fascial fibroblasts from Dupuytren's nodules. Different stiffness hydrogels (soft ~1 kPa and stiff ~ 50 kPa) were used as cell culture matrix to mimic the mechanical properties of the natural tissues, and atomic force microscopy step response force curves were used to discriminate between elastic and viscous properties of cells...

Dupuytren's disease (fibromatosis of the palmar fascia, benign neoplastic fibromatosis, Dupuytren's contracture) is a disease characterized by growth and successive contracture of single parts of the palmar aponeurosis. This condition is known and has been treated for several centuries. In the advanced stages of the disease, it leads to significant limitation of hand function, resulting in reduced quality of life of the patient. Dupuytren's disease (DD) is a life-long disease with a variable course and a heterogeneous clinical presentation...

Dupuytren's disease (DD) is a rare connective tissue disorder resulting in progressive fibrosis and thickening of the palmar fascia, and contracture of the fingers due to excessive collagen deposition. Staged surgical interventions are reserved for severe cases, yet worsening of fibrosis and contracture of fingers post-surgery, has been reported to have a recurrence rate as high as 85%. Here, the authors report on use of viable cryopreserved placental membrane (vCPM) allograft as an adjunct to open fasciectomy...

Background: The pathogenesis of Dupuytren's disease (DD) remains unclear. An embryonic stem cell (ESC)-like population in the endothelium of the microvessels around tissues that expresses components of the renin-angiotensin system (RAS) has been reported. This study investigated if this primitive population expresses cathepsins B, D, and G, that contribute to RAS bypass loops. Methods: 3,3-Diaminobenzidine immunohistochemical (IHC) staining for cathepsins B, D, and G was performed on sections of formalin-fixed paraffin-embedded DD cords (n = 10) and nodules (n = 10)...

INTRODUCTION: Dupuytren's contracture (DC) is a chronic fibroproliferative disorder of the palmar fascia which leads to flexion contracture in one or more fingers. There is no definitive cure for DC, and treatment aims at relieving symptoms by releasing the contracture using percutaneous or operative techniques. METHODS AND ANALYSIS: We planned a prospective, randomised, controlled, outcome assessor-blinded, three-armed parallel 1:1:1, multicentre trial comparing the effectiveness and cost of (1) collagenase clostridium histolyticum injection followed by limited fasciectomy in non-responsive cases, (2) percutaneous needle fasciotomy followed by limited fasciectomy in non-responsive cases and (3) primary limited fasciectomy during short-term and long-term follow-up for Tubiana I-III stages DC...

INTRODUCTION: There are few data in the scientific literature about the innervation of fasciae of the hand. The present study first elucidates the density and location of nervous structures in the palmar aponeurosis and, for comparison, in the flexor retinaculum (both can be considered specializations of the deep fascia of the upper limbs). Second, it compares non-pathological with pathological palmar aponeurosis. MATERIALS AND METHODS: Samples of non-pathological fascia were taken from the flexor retinaculum and palmar aponeurosis of 16 upper limbs of unembalmed cadavers...

BACKGROUND: Dupuytren's contracture produces a progressive flexion contracture of the affected fingers. Collagenase Clostridium histolyticum produces breakdown of the cord in the hand and/or finger(s) that tightens as a result of the disease creating a contracture, allowing manual traction and cord rupture. One of the side effects is spontaneous skin laceration when the finger is extended. OBJECTIVES: To evaluate the development of skin lacerations in Dupuytren's contracture treated with collagenase Clostridium histolyticum, to determine predisposing factors, and evaluate the effectiveness of 2 different treatments (antiseptic and non-antiseptic dressings)...
