Femoral biceps injury

Sami Shalhoub, Adam Cyr, Fallon Fitzwater, Lorin P Maletsky
A change in hamstring strength and activation is typically seen after injuries or invasive surgeries such as anterior cruciate reconstruction or total knee replacement. While many studies have investigated the influence of isometric increases in hamstring load on knee joint kinematics, few have quantified the change in kinematics due to the variation in medial to lateral hamstring force ratio. This study examined the changes in knee joint kinematics on eight cadaveric knees during an open chain deep knee bend for six different loading configurations: five loaded hamstring configurations that varied the ratio of a total load of 175 N between the semimembranosus and biceps femoris and one with no loads on the hamstring...

OBJECTIVE: To explore selection and method of tissue flaps for the repair of severe defects of skin and soft tissue around the knee joints. METHODS: Fifty-four patients with wounds around the knee joints, all accompanied by exposure or necrosis of tendon or bone and exposure of prosthesis, were hospitalized in our burn center from June 2008 to December 2014. Five of them were with knee joint injury. After thorough debridement or tumor resection, the wound area ranged from 5 cm × 5 cm to 46 cm × 22 cm...

OBJECTIVE: To evaluate the involvement of the iliotibial band (ITB), the anterolateral ligament (ALL), and the anterior arm of the biceps femoris in MRI-diagnosed Segond fracture and to evaluate other associated findings of Segond fracture. MATERIALS AND METHODS: We retrospectively reviewed the MRI of 13 cases of Segond fracture. The studies included proton density-weighted, T2-weighted, and proton density-weighted with fat saturation images in the three planes...

Internal tibial rotation with the knee close to full extension combined with valgus collapse during drop landing generally results in non-contact anterior cruciate ligament (ACL) injury. The purpose of this study was to investigate the relationship between internal rotation of the knee and muscle activity from internal and external rotator muscles, and between the internal rotation of knee and externally applied loads on the knee during landing in collegiate basketball players. Our hypothesis was that the activity of biceps femoris muscle would be an important factor reducing internal knee rotation during landing...

BACKGROUND: There has been concern for iatrogenic injury to the peroneal nerve with posterolateral femoral tunnel placement in double-bundle anterior cruciate ligament reconstruction. HYPOTHESIS: The common peroneal nerve and biceps tendon are at increased risk for injury by the guide wire as the knee is brought into increased extension. STUDY DESIGN: Controlled laboratory study. METHODS: An anatomical descriptive study was performed on 10 cadaveric knees (ages 49-67 years)...

Functional muscle transfer, e.g., biceps muscle replacement. CONTRAINDICATIONS: Poor soft-tissue conditions or lesions on both thighs. No recipient vessels. Inadequate personnel and/or technical resources. SURGICAL TECHNIQUE: Approach via a longitudinal medial incision or via the thigh flexion fold...

OBJECTIVES: Our objectives were to determine retrospectively the prevalence, patients' demographics, mechanism of injury, combination of torn ligaments, associated intra-articular and extra-articular injuries, fractures, bone bruises, femoral-tibial alignment and neurovascular complications of knee dislocations as evaluated by magnetic resonance (MR) imaging. MATERIALS AND METHODS: From 17,698 consecutive knee examinations by magnetic resonance imaging (MRI) over a 6-year period, 20 patients with knee dislocations were identified...

OBJECTIVE: The fibular collateral ligament (FCL)-biceps femoris (BF) bursa is not a commonly known location for calcific bursitis. A case of FCL-BF calcific bursitis is presented. CLINICAL FEATURES: An 18-year-old man had a blunt trauma on the lateral side of his right knee approximately 1 year before his examination. The pain and physical distortion developed in the trauma region over time. Physical examination revealed a 30 degrees flexion contracture and slight valgus deformity in the right knee...

OBJECTIVE: To explore the clinical characteristic of the multiple-ligament injured knee and evaluate the protocol, technique and outcome of treatment for the multiple-ligament injured knee. METHODS: From October 2001 to March 2005, 9 knees with combined anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) tears in 9 patients were identified with clinical and arthroscopic examinations. Of them, 5 knees were combined with ruptures of posteromedial corner (PMC) and medial collateral ligament (MCL), 4 with disruptions of posterolateral corner (PLC), 2 with popliteal vascular injuries and 1 with peroneal nerve injuries...

OBJECTIVE: The purpose of this study was to evaluate associated knee injuries using MR imaging in patients with the "arcuate" sign, a term referring to avulsion fracture of the proximal fibula on conventional radiographs. MATERIAL AND METHODS: MR imaging of 18 cases (17 patients, both knees in one patient) with the arcuate sign on conventional radiographs was retrospectively interpreted to evaluate the associated meniscal, ligamentous, and bony injuries. In 12 cases, MR findings were correlated with surgical results...

The histological aspects of second-intention healing were studied in 5 horses and 5 ponies. Biopsies were taken weekly from standardised wounds on the metatarsus and femoral biceps muscle of one horse and one pony. Sections were stained to enable cell counting and the detection of DNA synthesis, fibrin, smooth muscle actin (SMA), collagen, and bacteria. In the ponies, the number of polymorphonuclear leucocytes (PMNs) was high during the first 3 weeks and subsequently decreased rapidly. In the horses, the initial number of PMNs was lower, but remained persistently elevated during the evaluation period...

Clinical evaluation of posterolateral complex injuries of the knee can be difficult. To determine if magnetic resonance imaging can assist in decision-making in the treatment of posterolateral complex injuries, six consecutive patients with acute posterolateral knee trauma were imaged preoperatively with standard magnetic resonance imaging sequences. Magnetic resonance imaging findings were then correlated with results of examination under anesthesia or open lateral reconstruction. There were five complete lateral complex injuries (grade III) and one partial tear...

Animal models of peripheral nerve ischemia have yielded variable results. The question of whether post-ischemia re-establishment of blood flow to the nerves augments injury has not been examined. To study this question, the ipsilateral common iliac and femoral arteries were occluded with arterial snares for 3 hours in rats; 14C-butanol tissue distribution was then used to measure blood flow in both sciatic and posterior tibial nerve trunks and in both biceps femoris muscles during occlusion and reperfusion...

UNLABELLED: The relative importance of nerve versus muscle injury in limb ischemia-reperfusion is poorly understood. We used 14C-butanol tissue distribution to measure regional blood flow simultaneously in the proximal and distal sciatic, the posterior tibial nerve trunk (NBF), and biceps femoris muscle (MBF) of rats during 3 hours of occlusion of the ipsilateral iliac and femoral arteries and subsequently for up to 9 days of reperfusion. Limb motor function was also serially assessed...

To understand the role of the lateral thigh flap in head and neck reconstruction, we performed injection studies and anatomic dissections in 2 fresh and 61 preserved cadaver extremities followed by 10 clinical cases involving defects after tumor ablation. The flap, based on the third perforator of the profunda femoris artery, is designed on the posterolateral aspect of the distal thigh. The pedicle courses through the biceps short head, allowing optional transfer of this muscle. Defects of the oral cavity, pharynx, cervical esophagus, and external skin were successfully restored...
