Femoral biceps injury

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...

PURPOSE: This study presents the 2- to 10-year (24 to 120 month) results of 41 chronic arthroscopically assisted combined posterior cruciate ligament (PCL)-posterolateral reconstructions evaluated preoperatively and postoperatively using Lysholm, Tegner, and Hospital for Special Surgery knee ligament rating scales, KT-1000 arthrometer testing, stress radiography, and physical examination. TYPE OF STUDY: Case series. METHODS: This study population included 31 men and 10 women with 24 left and 17 right chronic PCL-posterolateral knee injuries with functional instability...

PURPOSE: This study presents the 2- to 10-year results of 35 arthroscopically assisted combined anterior cruciate ligament and posterior cruciate ligament (ACL/PCL) reconstructions evaluated preoperative and postoperatively using Lysholm, Tegner, and Hospital for Special Surgery knee ligament rating scales, KT-1000 arthrometer testing, stress radiography, and physical examination. TYPE OF STUDY: Case series. METHODS: This study population included 26 men and 9 women with 19 acute and 16 chronic knee 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...

A rare case of an isolated rupture of the biceps femoris tendon at its insertion to the femoral head is presented. Delayed surgical repair has not been previously reported. In this patient, a successful repair was carried out four months after the injury.

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...

The use of percutaneous stimulation for twitch superimposition in the human quadriceps has been compared with stimulation via the femoral nerve. It was found that the relationship between the extra force generated by the twitch and the level of voluntary contraction was independent of the percentage of the muscle stimulated. The technique was used to study activation of the quadriceps and biceps in a group of young healthy adults, and quadriceps activation in patients with musculo-skeletal disorders. The majority of subjects could fully activate their muscles during brief isometric contractions...

A method for reconstruction of skin defects around the knee using the lateral genicular artery flap is presented. This flap is supplied mainly by the cutaneous perforator of the superior lateral genicular artery. On the basis of ten cadaver dissections, we found that the nutrient artery is reliable, penetrates the deep fascia at a small triangular area surrounded by the lateral femoral condyle, the vastus lateralis, and the short head of the biceps femoris, and anastomoses predominantly with the lateral perforators of the profunda femoris artery in the midlayer of the subcutaneous fatty tissue...
