The caffeine contracture of normal human muscle, which has been used as a model for malignant hyperpyrexia, is greatly potentiated by halothane. Prior administration of procaine markedly reduces the halothane-potentiated caffeine contracture, and procaine given at the height of the contracture induces relaxation. Lignocaine, on the other hand, produces a variable response and sometimes increase...

Isolated perfused paced hearts from rats rendered hypothyroid by chronic administration of propylthiouracil have a delayed onset of ischemia-induced myocardial contracture in contrast to hearts from control rats. In addition, the time to reach maximum contracture is delayed, and the magnitude of the contracture pressure is reduced. Preischemia myocardial adenosine triphosphate (ATP) values in t...

Contracture of the quadriceps femoris in children leads to limited knee flexion.1 Fairbank and Barret2 and Hnevkovsky3 believed the contracture was congenital or secondary to progressive idiopathic fibrosis of the vastus intermedius. Lloyd-Roberts and Thomas4 stipulated that multiple injections into the thigh might cause the contracture. Proximal release in the early stage and distal release in...

Objective: Capsular contracture, the most common complication following breast augmentation with implants, is a complex inflammatory reaction that ultimately leads to fibrosis at the contact site between the implant and tissue. A number of peri-, pre-, and postoperative techniques have been postulated and implemented by many surgeons to reduce the incidence of capsular contracture. Breast massa...

BACKGROUND "The terrible disability of irreversible ischaemic flexion contracture of the metacarpi and digits known as Volkmann's contracture can be avoided in the vast majority of cases, but never completely cured" (M. Koszla). A modification of Colzi's forgotten technique for the treatment of Volkmann's contracture is presented together with our treatment outcomes. MATERIAL AND METHOD The C...

Gluteal muscle contracture is a clinical syndrome that involves contracture and distortion of the gluteal muscles and fascia fibers due to multiple causes. Physical examination demonstrates a characteristic gait due to hip adduction and internal thigh rotation. This study introduces a new minimally invasive method for surgical release of gluteal muscle contracture. Patients with gluteal muscle ...

Dupuytren's contracture is a condition commonly encountered by hand surgeons, although it is rare in the Asian population. Various surgical procedures for Dupuytren's contracture have been reported, and the outcomes vary according to the treatment modalities. We report the treatment results of segmental fasciectomies with multiple transverse incisions for patients with Dupuytren's contracture. ...

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...
