This paper reports an investigation of the incidence of persistent generalised joint laxity in patients with congenital dislocation of the hip and in normal school children. Capsular laxity has attracted much attention in studies of the etiology of congenital dislocation of the hip joint. At first it was thought to be an isolated result of mechanical stretching. but it is now usually considered...

Vaginal laxity and tissue architecture have often been overlooked as contributing etiologic factors to female sexual dysfunction. Vaginal laxity can lead to decreased physical sensation during intercourse. This decrease in sensation is often coupled with a decrease in sexual satisfaction, which can affect a woman’s sense of sexual self-esteem and her relationship with her sexual partner. Indeed...

introduction the abducent nucleus is located in the upper part of the rhomboid fossa beneath the fourth ventricle in the caudal portion of the pons. the abducent nerve courses from its nucleus, to innervate the lateral rectus muscle. this nerve has the longest subarachnoid course of all the cranial nerves, it is the cranial nerve most vulnerable to trauma. it has been reported that 1% to 2.7% o...

The Ehlers-Danlos syndromes (EDS) are a heterogeneous group of heritable connective tissue disorders characterized by joint hypermobility, skin extensibility, and tissue fragility. This communication briefly reports upon the neurological manifestations that arise including the weakness of the ligaments of the craniocervical junction and spine, early disc degeneration, and the weakness of the ep...

Superior dislocation of the patella without patellar ligament injury is an extremely rare condition. A review of the English-language literature found only 23 reported cases. In addition, the primary factor for dislocation in most of these cases was considered to be osteophytes in the inferior pole of the patella and the anterior surface of the femoral condyle; only 1 case had no osteophytes. W...

Introduction Chronic post-traumatic dislocation of the patella is rare and results in persistent dislocation throughout the arc of motion of the knee. Whereas newborns with trochlear dysplasia may exhibit congenital patellar dislocation, typical delayed presentation in adults is often due to trauma and can progress to painful motion and secondary osteoarthritis. Although rare, recurrent disloca...

OBJECTIVE To determine whether muscle strength, proprioceptive accuracy, and laxity are associated with self-reported knee instability in a large cohort of knee osteoarthritis (OA) patients, and to investigate whether muscle strength may compensate for impairment in proprioceptive accuracy or laxity, in order to maintain knee stability. METHODS Data from 283 knee OA patients from the Amsterda...

PURPOSE Females vary substantially in their multiplanar cyclic knee laxity changes across the menstrual cycle. The biomechanical implications of these cyclic changes are relatively unknown. Our purpose was to first cluster females based on their cyclic changes in anterior knee laxity (AKL), genu recurvatum (GR), varus-valgus (VV), and internal-external (IER) rotation knee laxity across the mens...

PURPOSE To evaluate torque and the hamstring/quadriceps ratio of the knee of athletes with and without anterior cruciate ligament laxity. METHODS Twenty-eight male athletes, 19 without anterior cruciate ligament laxity and 9 with anterior cruciate ligament laxity, were evaluated with an isokinetic machine model Cybex 770. The peak torque of quadriceps and hamstrings was compared, and the hams...
