abstract background and aim: lack of balance in pattern and activity of quadriceps and hamstring muscles increases the risk of anterior cruciate ligament injury (acl). the purpose of the present study was to investigate the changes in pattern and activity of vastus medialis and semitendinosusmuscles in landing from different heights and to understand if these changes will increase the risk of a...

The objectives of this experiment were to determine the extent of variation in proteolysis, sarcomere length, and collagen content among pork muscles and the association of those factors with tenderness variation among muscles at 1 d postmortem. Twenty-three white composite barrows were slaughtered and carcasses (66 kg) were chilled at 0 degrees C for 24 h. At 1 d postmortem, the longissimus lu...

Proximal junctional kyphosis is an increasingly recognized complication following long-segment posterior spinal fusion for adult spinal deformity. The authors describe a novel technique for interspinous ligament reinforcement at the proximal adjacent levels using a cadaveric semitendinosus tendon graft secured with an Ethibond No. 2 double filament (Ethicon, Somerville, New Jersey) via the Krac...

Abstract The objective of this study was to determine the effect chronic inflammation during late gestation on offspring muscle development. Starting at gestational day (GD) 70, first-parity gilts were administered either lipopolysaccharide (LPS, n=7) or saline (CON, n=8) via jugular venipuncture every other until GD 84. LPS initially given 10 µg/kg BW and increased by 12% each instance adminis...

Much controversy exists regarding the potential advantages and disadvantages of various graft choices for anterior cruciate ligament reconstruction. Advocates of hamstring autografts often cite the limited apparent morbidity associated with semitendinosus or semitendinosus and gracilis harvest, including evidence that hamstring tendons may regenerate after harvest. In this article, we attempt t...

The effect of decapitation on semitendinosus muscle growth and development was studied in the fetal pig. Pig fetuses were decapitated at 45 d of gestation and histochemical and biochemical analyses conducted at 110 d of gestation. Decapitation prevented or delayed the conversion of secondary fibers from Type II to Type I histochemistry as is characteristic of the normal semitendinosus. Morpholo...

INTRODUCTION Isolated rupture of the distal semitendinosus is rare, and as a result, there is paucity of evidence over the best method of managing the injury, that is, surgical or nonsurgical, particularly in light of the fact that the tendon is routinely harvested for anterior cruciate ligament (ACL) reconstruction. We present the cases of 2 elite sprinters with isolated ruptures of the distal...
