The biceps femoris has a long and a short head. The proximal long head is inserted at the tuber ischiadicum and the short head at the linea aspera. Distal it inserts at the lateral side of the head of the fibula. It helps in the extension, external rotation of the hip, and flexion of the knee. 1 A rupture of the distal insertion of this muscle is a very rare injury. In the literature, we were only able to find some disparate case reports. 2-5 Thus, it is in our interest to report this case. Case PresentationA 65-year-old man as he was moving a carpet had stretched his right leg and felt a stabbing pain in the laterodorsal distal tight. He could walk but felt instability in the knee. In the clinical exam, there was a depression in regard to the dorsolateral lateral epicondylus. A strength of two-fifth of the flexion of the knee was also there. There was no intraarticular swelling, no meniscus pathology, no pathological drawer, and the collateral ligaments were stable. An ultrasound was performed but due to the intramuscular hematoma, it was not possible to identify the injury. Therefore, a magnetic resonance imaging (MRI) was performed.On the MRI (►Fig. 1), we could follow cranially the distal biceps femoris during 3 cm before a complete rupture of the tendon around the knee. There is a 6-cm dehiscence and tendon retraction with an extended hematoma. The other structures of the knee were intact. With this pathology and the strength deficit, we decided to repair the tendon. After suture with FiberWire of the tendon, we were able to totally stretch the knee with the hip a 0-degree flexion (►Figs. 2 and 3). Postoperatively, we limited the knee extension to 30 degrees with a free flexion in a splint for 6 weeks and with only a 20 kg weight bearing. OutcomeThe patient did not follow the 20 kg weight bearing. After 6 weeks, the patient was able to walk again without limitation or instability. The tendon was difficult to palpate as there was a persistence of a swelling in the operative site. DiscussionAn isolated rupture of the biceps femoris is extremely rare. It is often associated with complex injury of the knee or injury of the posterolateral capsular ligament complex. 6 Most of the hamstring injury are proximal or in muscle belly. 7 Other isolated distal hamstring injury such as the semimembranosus is even more rare. This can be explained as the biceps femoris is the strongest flexor muscle, biomechanical study measured a 75% loss of strength of the knee flexion by resection of the muscle. 5 With these elements, we could conclude that an operative treatment is the best solution, but as stated previously, there are very few studies about this injury, not enough to have a consensus. There are also studies of a conservative treatment which can lead to full recovery. 5 Kusma et al 8 tried to summarize the outcome of nine case reports, where only one study was treated conservatively.

stiffness and pulse wave velocity / Aorta and carotid arteries 137 (0.94 to 1.01) p = 0.096; Obesity OR = 0.47 (0.29 to 1.77) p = 0.003 and Diabetes OR = 2.41 (1.15 -5.05) p = 0.020. Conclusions: According to the results obtained, genetic polymorphisms variables were not in the multivariate analysis equation to determine the increase of the PWV, which can be explained either by being included in the selected variables such as hypertension, or on the other hand, they may not have enough strength to remain in the equation. So, according to this study, PWV has much more to do with behaviors and traditional risk factors than the genetic heritage.P883 Endothelial dysfunction, pulse wave velocity and augmentation index are correlated in subjects with systemic arterial hypertension?

Background. Traumatic hip dislocation (THD) is an orthopaedic emergency that requires rapid reduction. THD is generally encountered in high-energy trauma. THD with low-energy trauma is extremely rare, even more so in the elderly. Methods/Results. We report the case of a 72-year-old woman who presented to the emergency department with anterior superior left hip dislocation after a low-energy trauma. Results. The patient was initially treated with closed reduction. Because of recurring dislocation, closed reduction was performed a second time. Magnetic resonance imaging showed no soft tissue interposition. At 12 week follow-up, the patient complained of intractable hip pain and was treated with total hip arthroplasty. The post-operative course was uneventful with a return to pre-injury functional mobility. We also conducted a review of the literature with regard to anterior hip dislocation in the population aged 70 years or more. Conclusion. THD can be associated with significant morbidity. Time to reduction is considered essential in improving functional outcomes. In the case of poor functional outcomes, total hip arthroplasty should be considered.
