Review
Joint contractures and acquired deforming hypertonia are frequent in dependent older people. The consequences of these conditions can be significant for activities of daily living as well as comfort and quality of life. They can also negatively affect the burden of care and care costs. However, etiological factors and pathophysiologic mechanisms remain only partly understood. As a result, preventive interventions and treatments focus entirely on controlling symptoms rather than the causes. Moreover, the effectiveness of these interventions remains to be validated. The purpose of this position paper is to present current data on etiological factors contributing to the development of joint contractures and acquired deforming hypertonia in older people. The pathophysiologic mechanisms of joint contractures in animal models are also presented.

Review
The current study ushers in a comprehensive review in clinical research to demonstrate the prevalence of musculoskeletal (MSK) complications in diabetes mellitus and the most relevant clinical aspects. In particular, revealing the early symptoms of the disorders, the pathology lurking behind the complications and their optimal management. In diabetes mellitus, MSK complications are common and are largely due to similar pathogenetic factors responsible for the internal organ complications associated with diabetes leading to chronic low-intensity inflammatory processes. MSK disorders develop by vasculopathy, neuropathy, arthropathy or combinations of the above, which are not specific to diabetes. However, their prevalence is significantly increased in diabetes and contributes to the disability impairing patients' quality of life. Locomotor disease affects approximately 34.4-83.5 % of patients suffering from type-2 diabetes mellitus. Several musculoskeletal abnormalities (cheiroarthropathy, Dupuytren's contracture, trigger finger, ect.) can be diagnosed upon physical examination, although certain symptoms (frozen shoulder, neurogenic arthropathy, septic arthritis, etc.) require differential diagnostic considerations. Early identification regarding characteristic symptoms in the treatment reducing inflammation and pain, followed with increasingly strenuous exercise therapy, aligned with optimal management of carbohydrate metabolism, proves essential in alleviating MSK complications.

IMPORTANCE
Owing to its tendency to recur, Dupuytren contracture often requires multiple treatments, which places additional economic burden on health care. The likelihood of contracture recurrence varies not only with treatment but also with disease characteristics, such as contracture severity and location, but prior cost-effectiveness analyses of Dupuytren contracture treatments have not considered these patient-specific disease characteristics.
OBJECTIVE
To identify the most cost-effective treatment regimen for patients with recurrent Dupuytren contracture.
DESIGN, SETTING, AND PARTICIPANTS
This economic evaluation was conducted with state-transition microsimulation modeling using data from published studies and Medicare. A simulated cohort of 10 000 individuals with Dupuytren contracture was created. Patients could transition yearly between the following health states: symptom-free, symptomatic, and death. Available treatments were collagenase clostridium histolyticum injection, percutaneous needle aponeurotomy (PNA), and limited fasciectomy (LF); individuals randomly chose any treatment when symptomatic. Patients were limited to 3 rounds of treatment for a contracture affecting 1 joint, totaling 27 unique combinations. If the contracture recurred after 3 treatments, patients lived with the disease for the remainder of life.
EXPOSURES
PNA, collagenase clostridium histolyticum injection, or LF.
MAIN OUTCOMES AND MEASURES
Quality-adjusted life-years (QALYs), total costs (in US dollars), and incremental cost-effectiveness ratios (ICERs). A willingness-to-pay threshold of $100 000 per quality-adjusted life-year was used to assess cost-effectiveness.
RESULTS
For the base case scenario of a patient aged 60 years with recurrent, low-severity metacarpophalangeal (MCP) joint contracture, repeated PNA treatment was the only cost-effective treatment (2 PNA treatments followed by LF vs 3 PNA treatments, ICER [Monte Carlo SE]: $212 647/QALY [$36 000/QALY]). For recurrent high-severity MCP joint contractures, treatment regimens composed of PNA and LF were cost-effective (ICER [Monte Carlo SE], $93 932/QALY [$16 500/QALY]). LF was cost-effective for high-severity MCP joint contracture (ICER [Monte Carlo SE], $98 624/QALY [$26 233/QALY]). For recurrent proximal interphalangeal (PIP) joint contractures, PNA was the only cost-effective treatment, regardless of severity (eg, 2 PNA treatments followed by LF vs 3 PNA treatments for low-severity PIP joint contracture, ICER [Monte Carlo SE]: $263 726/QALY [$29 000/QALY]). Any combination with collagenase clostridium histolyticum injection compared with 3 PNA treatments had an ICER greater than $100 000 per QALY. Probabilistic sensitivity analysis estimated a 44%, 15%, 41%, and 52% chance of a regimen consisting of only PNA being cost-effective in low-severity MCP, high-severity MCP, low-severity PIP, and high-severity PIP joint contractures, respectively.
CONCLUSIONS AND RELEVANCE
The results of this study suggest that LF is a cost-effective intervention for recurrent high-severity MCP joint contractures. For recurrent low-severity MCP joint contractures and PIP joint contractures of all severity levels, PNA was the only cost-effective intervention. Collagenase clostridium histolyticum injections were not a cost-effective intervention for recurrent Dupuytren contracture and should not be preferred over PNA or LF.

Muscle contracture is an abnormal pathologic process resulting in fibrosis and muscle atrophy, which can lead to limitation of joint motion. To establish a diagnostic method to detect muscle contracture and a method to control its progression, we investigated an appropriate method to create an animal model of quadriceps contracture using rats. Eighteen Wistar rats were divided into three groups, and bilateral hindlimbs were immobilized with either a cast (Group I), a Velcro hook-and-loop fastener (Group V), or steel wire (Group S) with the knee and ankle joints in extension position for two weeks. Five rats in a control group (Group C) were not immobilized. After two weeks, the progression of quadriceps contracture was assessed by measuring the range of joint motion and pathohistological changes. Muscle atrophy and fibrosis were observed in all immobilization groups. The knee joint range of motion, quadriceps muscle weight, and muscle fiber size decreased only in Group S compared to the other immobilization groups. Stress on rats due to immobilization was less in Group S. These results indicate that Group S is the superior quadriceps contracture model. This model aids research investigating diagnostic and therapeutic methods for muscle contracture in humans and animals.

Finger stiffness may arise from injuries, surgeries, or hand-related medical conditions, impacting hand function and overall well-being in daily life. Rehabilitation and hand therapy play a crucial role in restoring optimal range of motion, strength, and functionality. This article introduces the Self-Assisted Finger Stiffness Splint (SFSS), a dynamic splint designed for active finger movement applicable in post-trauma or postoperative rehabilitation. SFSS empowers patients to perform self-administered stretching exercises, expediting recovery and improving compliance. Its versatility extends to postoperative rehabilitation, covering cases like tenolysis of extensor tendons or rehabilitation after fracture healing. While particularly effective for proximal interphalangeal joint (PIPJ) and metacarpophalangeal joint (MCPJ) stiffness, SFSS remains valuable for managing isolated finger stiffness and proves beneficial in addressing multiple-digit stiffness.

BACKGROUND
The diagnosis and treatment of fibro-adipose vascular anomaly (FAVA) of the limb remains challenging since this entity is rare and complex. This paper is aimed to describe the clinical and imaging features, staging and management of this underrecognized disease of the limb.
MATERIAL AND METHOD
Patients diagnosed with FAVA and managed between September 2019 and May 2022 in department of pediatric surgery & vascular anomalies of Xi'an international medical center hospital were retrospectively reviewed. Data extracted include age at presentation, previous diagnosis, affected muscles, symptoms, previous treatment, our management, and follow-up.
RESULTS
Thirty-two patients with FAVA were diagnosed and managed in our center. There was a female sex predominance, with 23 female (72%) and 9 male (28%) in the cohort. Only one lesion was noticed during infancy; the remaining presented at age 1 to 20 years (median, 7 years). The most commonly involved muscles were gastrocnemius (14/32, 44%) and soleus (13/32, 40%). Swelling (mass), pain and contractures were the most common presentations. MRI featured a heterogeneous and ill-defined intramuscular high signal intensity. Diseases were staged according to clinical features: stage I (pain stage, n = 4), stage II (contracture stage, n = 20) and stage III (deformity stage, n = 8). Patients with stage I disease underwent radical resection and obtained a cure. Patients with stage II disease received radical resection and possible Achilles lengthening, having an outcome of cure. Personalized treatment was required in patients with stage III disease, including radical/partial/staged resection, Achilles lengthening/tenotomy, joint capsulotomy, neurolysis/neurectomy, tendon transfer, stretching exercises, and oral sirolimus/alpelisib. Significant improvement of symptoms was achieved in most.
CONCLUSION
The most distinct features of FAVA include enlarging mass, severe pain and contracture. Based on distinct clinical and radiologic features, it is not difficult to make the diagnosis of FAVA. Earlier awareness of this disease can reduce misdiagnoses. Surgery-based comprehensive management can typically improve pain and contracture. Oral sirolimus or alpelisib plays an important role in treatment of unresectable lesions and major nerve involvement. Surgery alone can be curative in early stage FAVA.

Review
Joint immobilization is frequently administered after fractures and ligament injuries and can cause joint contracture as a side effect. The structures responsible for immobilization-induced joint contracture can be roughly divided into muscular and articular. During remobilization, although myogenic contracture recovers spontaneously, arthrogenic contracture is irreversible or deteriorates further. Immediately after remobilization, an inflammatory response is observed, characterized by joint swelling, deposit formation in the joint space, edema, inflammatory cell infiltration, and the upregulation of genes encoding proinflammatory cytokines in the joint capsule. Subsequently, fibrosis in the joint capsule develops, in parallel with progressing arthrogenic contracture. The triggers of remobilization-induced joint inflammation are not fully understood, but two potential mechanisms are proposed: 1) micro-damage induced by mechanical stress in the joint capsule, and 2) nitric oxide (NO) production via NO synthase 2. Some interventions can modulate remobilization-induced inflammatory and subsequent fibrotic reactions. Anti-inflammatory treatments, such as steroidal anti-inflammatory drugs and low-level laser therapy, can attenuate joint capsule fibrosis and the progression of arthrogenic contracture in remobilized joints. Antiproliferative treatment using the cell-proliferation inhibitor mitomycin C can also attenuate joint capsule fibrosis by inhibiting fibroblast proliferation without suppressing inflammation. Conversely, aggressive exercise during the early remobilization phases is counterproductive, because it facilitates inflammatory and then fibrotic reactions in the joint. However, the adverse effects of aggressive exercise on remobilization-induced inflammation and fibrosis are offset by anti-inflammatory treatment. To prevent the progression of arthrogenic contracture during remobilization, therefore, care should be taken to control inflammatory and fibrotic reactions in the joints.

Joint contracture (also known as arthrofibrosis) is a fibrotic joint disorder characterized by excessive collagen production to form fibrotic scar tissue and adhesions within joint capsules. This can severely affect day-to-day activities and quality of life because of a restricted range of motion in affected joints. The precise pathogenic mechanism underlying joint contractures is not fully understood. Lumican belongs to the class II small leucine-rich repeat proteoglycan superfamily, which makes up collagen fibrils in the extracellular matrix. Lumican is ubiquitously expressed in the skin, liver, heart, uterus and articular cartilage and has reported roles in cell migration, proliferation, angiogenesis and Toll-like receptor 4 signaling. Previous research has suggested that lumican is involved in the pathogenesis of several fibrotic diseases. Because joint contracture resembles a fibrotic disease, we aimed to investigate the role of lumican in the development of joint contracture in vitro. Here, we showed that protein levels were up-regulated in the fibrotic joint capsule versus control. We observed that lumican significantly enhanced the proliferation, migration and fibroblast-myofibroblast transition of synovial fibroblasts. Moreover, lumican led to increased transcription of alpha-smooth muscle actin, matrix metallopeptidase 9, Collagen I, plasminogen activator inhibitor 1 and transforming growth factor-β in vitro. Lumican treatment promoted collagen lattice contraction in a dose-dependent manner as early as 24 h after treatment. Thus, our studies reveal that lumican could promote fibroblast-myofibroblast transition and joint contracture.

Review
Systemic sclerosis (scleroderma, SSc) is an autoimmune disease that causes significant dysfunction to multiple organ systems, including the musculoskeletal system. It poses significant challenges to the hand surgeon, including calcinosis, ischemic changes, Raynaud phenomenon, tendinopathies, synovitis, and joint contractures. Patients with SSc also suffer from multiorgan dysfunction, which makes them high-risk surgical patients. The hand surgeon must understand the pathophysiology, treatment strategies, and special operative considerations required in this population to avoid complications and help maintain or improve hand function.

BACKGROUND
Joint contracture causes a decrease in range of motion (ROM), which severely affects activities of daily living of patients. We have investigated the effectiveness of a multidisciplinary rehabilitation on joint contracture by rat model.
METHODS
We used 60 Wistar rats in this study. The rats were divided into five groups as follows: group 1 was the normal control group; except the group 1, we created left hind limb knee joint contracture using Nagai method for other four groups. The joint contracture modeling group 2 was the model control group for monitoring the spontaneous recovery, and other three groups were given different rehabilitation treatments; for example, group 3 was treadmill running group; group 4 was medication group; group 5 was treadmill running plus medication group. The left hind limbs knee joint ROM and the femoral blood flow indicators (FBFI) including PS, ED, RI, and PI were measured right before and after the 4 weeks of rehabilitation.
RESULT
After 4 weeks of rehabilitation treatments, the measured values of ROM and FBFI are compared with the corresponding values of group 2. Firstly, we did not see clear difference in the values of ROM and FBFI for group 2 before and after 4 weeks spontaneous recovery. The improvement of left lower limb ROM for group 4 and group 5 as compared to the group 2 was statistically significant (p < 0.05), whereas a less recovery for group 3 was observed. However as compared to the group 1, we did not observe full recovery in ROM of group 4 and group 5 after 4 weeks of rehabilitation. The PS and ED level for rehabilitation treatment groups was significantly higher than those modeling ones (Tables 2, 3, Figs. 4, 5), while the RI and PI values show the contrary trends (Tables 4, 5, Figs. 6, 7).
CONCLUSION
Our results indicate that multidisciplinary rehabilitation treatments had a curative effect on both contracture of joints and the abnormal femoral circulations.
