We evaluated the morphological framework of the pes anserinus in both knees of ten Nigerian cadavers and we observed high degree of variability in its morphology and location. The pes anserinus inserted specifically on the superior half of the media border of the tibia, as far inferiorly as 124.44 mm to the tibial tuberosity (prolonged insertion). The insertion was also joined to the part of ti...

This study aims to determine whether a low weight at birth may influence muscle characteristics and meat quality traits in pigs at market weight. At 68 days of age, a total of 30 female piglets were assigned within litter to one of the two experimental groups (n = 15 per group): low birth weight (LW: 1.05 + 0.04 kg) or heavy birth weight (HW: 1.89 + 0.02 kg). Pigs were penned individually and f...

The interaction between the semitendinosus muscle and both hip and knee joint angles was examined in the frog (Ranu pip&s) hindlimb. Sarcomere length was measured by laser diffraction in passive muscle during hip and knee rotation. A model was then developed to predict semitendinosus sarcomere length ;Ls a function of both hip and knee Rexion angle. Based on published frog muscle fiber length-t...

Objectives: To determine if immobilization of the knee at varying degrees of knee flexion will limit the surface electromygraphical (sEMG) activity of hamstring muscles during crutch-assisted ambulation. Methods: Ten healthy participants walked with crutches with the knee maintained at 0°, 30°, 60° and 90° of knee flexion, both with and without a brace. The leg was non-weight bearing for all tr...

The hamstring muscle group consists of three muscles in the posterior thigh; the semitendinosus (ST) and the semimembranosus (SM) are located at the medial side, the biceps femoris at the lateral side (BF) [1]. The biceps femoris has two heads, which are anatomically and functionally distinct; the short (BFsh) and the long (BFlh) head. The semitendinosus and long head of the biceps femoris have...

Objective  The purpose of the study is to evaluate the clinical results and return to sports in patients undergoing reconstruction of the Achilles tendon after minimally invasive reconstruction with semitendinosus tendon graft transfer. Methods  Eight patients underwent surgical reconstruction with a minimally invasive technique and tendon graft augmentation with ipsilateral semitendinosus tend...

BACKGROUND The aim of this study was to evaluate the therapeutic effect of autogenous semitendinosus graft and endobutton technique, and compare with hook plate in treatment of Rockwood type III acromioclavicular (AC) joint dislocation. METHODS From April 2012 to April 2013, we treated 46 patients with Rockwood type III AC joint dislocation. Patients were randomly divided into two groups: Gro...

Prone hip extension has been used as a self-perturbation task to test the stability of the lumbopelvic region. However, the relationship between recruitment patterns in the hip and trunk muscles and lumbopelvic kinematics remains unknown. The present study aimed to examine if the balance of hip and trunk muscle activities are related to pelvic motion and low back muscle activity during prone hi...

This prospective cohort study described return-to-play (RTP) data for different types of muscle injuries in male elite-level football players in Europe. Eighty-nine European professional teams were followed between 2001 and 2013. Team medical staff recorded individual player exposure and time-loss injuries. A total of 17,371 injuries occurred, including 5603 (32%) muscle injuries. From 2007, we...

OBJECTIVE To evaluate the diameter of the flexor tendons in preoperative magnetic resonance imaging (MRI) examinations and compare this with the diameter of the graft obtained intraoperatively. METHODS This was a retrospective longitudinal epidemiological study. Forty-four patients were eligible for the study and their MRI examinations and surgical data were evaluated. The tendons were measur...
