Review
Dupuytren's disease is a common benign fibromatosis of the palmar and digital fascia. The exact pathophysiology and epidemiology of this condition have not been entirely identified. Pathologic fibrous bands cause a flexion contracture of the metacarpal phalangeal joints and proximal interphalangeal joint. Treatment includes fasciectomy, needle fasciotomy, and enzymatic fasciectomy.

Review
Collagen VI exerts several functions in the tissues in which it is expressed, including mechanical roles, cytoprotective functions with the inhibition of apoptosis and oxidative damage, and the promotion of tumor growth and progression by the regulation of cell differentiation and autophagic mechanisms. Mutations in the genes encoding collagen VI main chains, and , are responsible for a spectrum of congenital muscular disorders, namely Ullrich congenital muscular dystrophy (UCMD), Bethlem myopathy (BM) and myosclerosis myopathy (MM), which show a variable combination of muscle wasting and weakness, joint contractures, distal laxity, and respiratory compromise. No effective therapeutic strategy is available so far for these diseases; moreover, the effects of collagen VI mutations on other tissues is poorly investigated. The aim of this review is to outline the role of collagen VI in the musculoskeletal system and to give an update about the tissue-specific functions revealed by studies on animal models and from patients' derived samples in order to fill the knowledge gap between scientists and the clinicians who daily manage patients affected by collagen VI-related myopathies.

Review
Post-traumatic knee stiffness and loss of range of motion is a common complication of injuries to the knee area. The causes of post-traumatic knee stiffness can be divided into flexion contractures, extension contractures, and combined contractures. Post-traumatic stiffness can be due to the presence of dense intra-articular adhesions and/or fibrotic transformation of peri-articular structures. Various open and arthroscopic surgical treatments are possible. A precise diagnosis and understanding of the pathology is mandatory prior to any surgical treatment. Failure is imminent if all pathologies are not addressed correctly. From a general point of view, a flexion contracture is due to posterior adhesions and/or anterior impingement. On the other hand, extension contractures are due to anterior adhesions and/or posterior impingement. This overview will describe the different modern surgical techniques for treating post-traumatic knee stiffness. Any bony impingements must be treated before soft tissue release is performed. Intra-articular stiff knees with a loss of flexion can be treated by an anterior arthroscopic arthrolysis. Extra-articular pathology causing a flexion contracture can be treated by open or endoscopic quadriceps release. Extension contractures can be treated by arthroscopic or open posterior arthrolysis. Postoperative care (analgesia, rehabilitation) is essential to maintaining the range of motion obtained intra-operatively.

Distal arthrogryposis (DA) is a collection of rare disorders that are characterized by congenital joint contractures. Most DA mutations are in muscle- and joint-related genes, and the anatomical defects originate cell-autonomously within the musculoskeletal system. However, gain-of-function mutations in PIEZO2, a principal mechanosensor in somatosensation, cause DA subtype 5 (DA5) through unknown mechanisms. We show that expression of a gain-of-function PIEZO2 mutation in proprioceptive sensory neurons that mainly innervate muscle spindles and tendons is sufficient to induce DA5-like phenotypes in mice. Overactive PIEZO2 causes anatomical defects through increased activity within the peripheral nervous system during postnatal development. Furthermore, botulinum toxin (Botox) and a dietary fatty acid that modulates PIEZO2 activity reduce DA5-like deficits. This reveals a role for somatosensory neurons: Excessive mechanosensation within these neurons disrupts musculoskeletal development.

Journal of Physiotherapy Apr 2017Is stretch effective for the treatment and prevention of contractures in people with neurological and non-neurological conditions? (Meta-Analysis)
Meta-Analysis
QUESTION
Is stretch effective for the treatment and prevention of contractures in people with neurological and non-neurological conditions?
DESIGN
A Cochrane Systematic Review with meta-analyses of randomised trials.
PARTICIPANTS
People with or at risk of contractures.
INTERVENTION
Trials were considered for inclusion if they compared stretch to no stretch, or stretch plus co-intervention to co-intervention only. The stretch could be administered in any way.
OUTCOME MEASURES
The outcome of interest was joint mobility. Two sets of meta-analyses were conducted with a random-effects model: one for people with neurological conditions and the other for people with non-neurological conditions. The quality of evidence supporting the results of the two sets of meta-analyses was assessed using GRADE.
RESULTS
Eighteen studies involving 549 participants examined the effectiveness of stretch in people with neurological conditions, and provided useable data. The pooled mean difference was 2 deg (95% CI 0 to 3) favouring stretch. This was equivalent to a relative change of 2% (95% CI 0 to 3). Eighteen studies involving 865 participants examined the effectiveness of stretch in people with non-neurological conditions, and provided useable data. The pooled standardised mean difference was 0.2 SD (95% CI 0 to 0.3) favouring stretch. This translated to an absolute mean increase of 1 deg (95% CI 0 to 2) and a relative change of 1% (95% CI 0 to 2). The GRADE level of evidence was high for both sets of meta-analyses.
CONCLUSION
Stretch does not have clinically important effects on joint mobility. [Harvey LA, Katalinic OM, Herbert RD, Moseley AM, Lannin NA, Schurr K (2017) Stretch for the treatment and prevention of contracture: an abridged republication of a Cochrane Systematic Review. Journal of Physiotherapy 63: 67-75].

Review
Arthrogryposis multiplex congenita (AMC) consists of congenital joint contractures that affect at least two joints. There are two types: in the first, arthrogryposis is an additional sign in the context of various pathologies (neuromuscular diseases); in the second, it is the main and constant symptom. In the first type, the progression of the causal underlying disease must be considered. In the second type, there are two specific forms: Amyoplasia corresponds to a significant congenital absence of muscles (epigenetic disease or vascular origin) while distal arthrogryposis has a genetic component and is transmissible. The orthopedic surgeon's purpose, which is usually to enhance movement, is not appropriate for an arthrogryposis patient. One must keep in mind that without muscle, movement is impossible. The goal differs between the upper and lower limbs: for the upper limb, it is to allow grasping, and, if possible, to bring the hand to the mouth; for the lower limb, it is to ensure ambulation with plantigrade support, and the knees extended, which is the only stable position possible with little to no muscles. The rehabilitation, orthoses and/or surgical techniques are chosen to achieve this singular aim. While it may appear modest, it is crucial for patients. The goal is to achieve useful mobility, not maximum mobility. This multidisciplinary treatment, which evolves over time, must be explained to the family to get its adherence.

Clinical Rehabilitation Mar 2021Does early treatment of spasticity with botulinum-toxin (BoNTA), in (hyper)acute stroke patients without arm-function, reduce contractures and improve function. (Randomized Controlled Trial)
Randomized Controlled Trial
OBJECTIVE
Does early treatment of spasticity with botulinum-toxin (BoNTA), in (hyper)acute stroke patients without arm-function, reduce contractures and improve function.
DESIGN
Randomised placebo-controlled-trial.
SETTING
Specialised stroke-unit.
PARTICIPANTS & INTERVENTION
Patients with an Action Research Arm Test (ARAT) grasp-score⩽2 who developed spasticity within six-weeks of a first stroke were randomised to receive injections of: 0.9%sodium-chloride solution (placebo) or onabotulinumtoxin-A (treatment).
OUTCOME-MEASURES
Spasticity, contractures, splint use and arm function (ARAT) were taken at baseline, 12-weeks post-injection and six-months after stroke. Additionally, spasticity and contractures were measured at weeks-two, four and six post-injection.
RESULTS
Ninety three patients were randomised. Mean time to intervention was 18-days (standard deviation = 9.3). Spasticity was lower in the treatment group with difference being significant between week-2 to 12 (elbow) and week-2 to 6 (wrist). Mean-difference (MD) varied between -8.5(95% CI -17 to 0) to -9.4(95% CI -14 to -5) µV.Contracture formation was slower in the treatment group. Passive range of motion was higher in the treatment group and was significant at week-12 (elbow MD6.6 (95% CI -0.7 to -12.6)) and week-6 (wrist MD11.8 (95% CI 3.8 to 19.8)). The use of splints was lower in the treatment group odds ratio was 7.2 (95% CI 1.5 to 34.1) and 4.2 (95% CI 1.3 to 14.0) at week-12 and month-6 respectively.Arm-function was not significantly different between the groups MD2.4 (95% CI -5.3 to 10.1) and 2.9 (95% CI -5.8 to 11.6) at week-12 and month-6 respectively.
CONCLUSION
BoNTA reduced spasticity and contractures after stroke and effects lasted for approximately 12-weeks. BoNTA reduced the need for concomitant contracture treatment and did not interfere with recovery of arm function.

Review
Arthrofibrosis, or rigid contracture of major articular joints, is a significant morbidity of many neurodegenerative disorders. The pathogenesis depends on the mechanism and severity of the precipitating neuromuscular disorder. Most neuromuscular disorders, whether spastic or hypotonic, culminate in decreased joint range of motion. Limited range of motion precipitates a cascade of pathophysiological changes in the muscle-tendon unit, the joint capsule, and the articular cartilage. Resulting joint contractures limit functional mobility, posing both physical and psychosocial burdens to patients, economic burdens on the healthcare system, and lost productivity to society. This article reviews the pathophysiology of arthrofibrosis in the setting of neuromuscular disorders. We describe current non-surgical and surgical interventions for treating arthrofibrosis of commonly affected joints. In addition, we preview several promising modalities under development to ameliorate arthrofibrosis non-surgically and discuss limitations in the field of arthrofibrosis secondary to neuromuscular disorders.
