Function and satisfaction after total knee arthroplasty (TKA) are partially linked to postoperative range of motion (ROM). Fixed flexion contracture is a recognized complication of TKA that reduces ROM and is a source of morbidity for patients. This study aimed to identify preoperative risk factors for developing fixed flexion contracture following TKA and to quantify the effect of fixed flexio...

It is possible that physical inactivity and prolonged sitting could lead to changes in muscle properties or bony limitations which may reduce passive hip extension. This study explored the association between extension sitting/physical activity patterns. Cross sectional study. The modified Thomas Test a clinical test used characterise flexion contracture. was measure across 144 individuals. In ...

Mechanisms of energy deprivation contracture were investigated in cultured chick embryo ventricular cells. In the presence of zero-extracellular-Na+, (choline chloride substitution)-nominal-zero-Ca2+ [( Ca2+] approximately 5 microM), exposure of ventricular cells to 1 mM cyanide (CN) and 20 mM 2-deoxyglucose (2-DG)-zero-glucose solution resulted in the development of a contracture (video motion...

BACKGROUND Although there are a few broadly agreed on contributory factors, the multifaceted causes of capsular contracture have remained unresolved for decades. This study investigates a variety of potential risk factors that contribute to capsular contracture in primary augmentation patients. METHODS The data used for this analysis include 5109 implants in 2560 primary augmentation patients...

In certain hemiplegic patients the tone in the flexor and adductor muscles is too great for the extensors and abductors. This may sometimes result in joint contracture. Hence every attempt must be made to promote extension and abduction of the affected limbs. Drug treatment is of limited use in these cases, though dantrolene may be used in doses increasing from 25 mg to 100 mg five times a day....

Malunions are a well-recognized complication of pediatric supracondylar humeral fractures. Results of corrective osteotomies vary, and complication rates have been reported to be as high as 40%. Considering the high rate of complications for malunion correction, we investigated the feasibility of arthroscopy. We present a technique for arthroscopic supracondylar osteotomy and percutaneous pinni...

Mechanisms of energy deprivation contracture were investigated in cultured chick embryo ventricular cells. In the presence of zero-extracellular-Na* (choline chloride substitution)-nominal-zero-Ca ([Ca] ~ 5 fiM), exposure of ventricular cells to 1 mM cyanide (CN) and 20 mM 2-deoxyglucose (2-DG)-zero-glucose solution resulted in the development of a contracture (video motion detector) in 5.9 ±0....

Vascular malformations of the muscle are rare non-proliferative vascular lesions, and few case reports have described intramuscular in upper extremities. may produce musculoskeletal deformities due to contracture. Symptomatic commonly treated with surgery interventional management. We report a malformation that could not be completely resected. It caused adduction contracture thumb hand. Sclero...
