CASE SUMMARY A 6-month-old cat was successfully treated for bilateral quadriceps contracture. Conventional treatments including surgery, dynamic flexion apparatus and physical therapy along with analgesics and non-steroidal anti-inflammatory drugs resulted in temporary clinical improvement that was relapsing. The initiation of supplementary corticosteroid treatment with prednisolone coincided w...

Rapid cooling contracture (RCC) was observed in frog toe muscles pretreated with caffeine, chlorpromazine (CPZ), or haloperidol (HPD). During rapid cooling contracture in the presence of caffeine (caffeine-RCC) tension developed to more than 0.8 of the maximum tetanic tension (P0). CPZ inhibited twitch but induced rapid cooling contracture (CPZ-RCC) between 50 and 150 microM; the tension satura...

Silicone breast implants have been used for breast augmentation and reconstructive surgery for the past 40 years. Capsular contracture is a relatively common complication (a capsule that forms around the breast implant, thereby causing a deformity and pain), and poses challenging problems for surgeons [1]. Clinically, patients with severe capsular contracture, such as those with capsular contra...

Changes in diastolic chamber distensibility (DCD) during hypoxemia and ischemia were studied in isolated-buffer-perfused rabbit hearts. Two minutes of hypoxemia (low PO2 coronary flow) resulted in a shift of the diastolic pressure-volume curve to the left, i.e., distensibility was decreased (hypoxemic contracture). In contrast, 2 minutes of ischemia (zero coronary flow) resulted in an initial s...

OBJECTIVE Capsular contracture is a common complication associated with reconstructive breast surgery. The optimal time interval between the completion of tissue expansion and placement of the permanent implant is arbitrary and incompletely studied in the literature. The aim of the study was to determine whether the time interval between completion of expansion and placement of the permanent im...

The effect of the extracellular Ca depletion on potassium contracture was investigated in single fibers isolated from frog semitendinosus muscle mainly in relation to its time and Na dependency. The shortening of plateau duration and the increase in the rate of relaxation of the potassium contracture appeared within 3--5 sec and 15 sec, respectively, after the fiber was immersed in Ca-free Na R...

Abnormal wound healing is likely to induce scar formation, leading to dysfunction, deformity, and psychological trauma in burn patients. Despite the advancement of medical care treatment, scar contracture in burn patients remains a challenge. Myofibroblasts play a key role in scar contracture. It has been demonstrated that myofibroblasts, as well as inflammatory cells, fibroblasts, endothelial ...

BACKGROUND Flexion of one elbow is essential to enable children with arthrogryposis to achieve independent function such as self-feeding and self-care of the face and hair. We analyzed the outcomes of posterior elbow capsulotomy with triceps lengthening for the treatment of elbow extension contractures in a series of children with arthrogryposis multiplex congenita. METHODS The medical record...

BACKGROUND Splinting as part of the overall post-surgical management of patients after release of Dupuytren's contracture has been widely reported, though there is variation in practice and criteria for using it. The evidence on its effectiveness is sparse, of poor quality and contradictory with studies reporting negative and positive effects. METHODS/DESIGN A multi-centre, pragmatic, randomi...
