This finding may suggest that PTE is an indicator of a more severe brain injury, rather than a complication that itself worsens outcome. PTE has also been found to be associated with worse social and functional outcomes but not to worsen patients rehabilitation or ability to return to work. However, people with PTE may have trouble finding employment if they admit to having seizures, especially if their work involves operating heavy machinery.The period of time between an injury and development of epilepsy varies, and it is not uncommon for an injury to be followed by a latent period with no recurrent seizures. The longer a person goes without developing seizures, the lower the chances are that epilepsy will develop. At least 80–90% of people with PTE have their first seizure within two years of the TBI. People with no seizures within three years of the injury have only a 5% chance of developing epilepsy. However, one study found that head trauma survivors are at an increased risk for PTE as many as 10 years after moderate TBI and over 20 years after severe TBI. Since head trauma is fairly common and epilepsy can occur late after the injury, it can be difficult to determine whether a case of epilepsy resulted from head trauma in the past or whether the trauma was incidental.The question of how long a person with PTE remains at higher risk for seizures than the general population is controversial.
A structure of minor importance in humans, the incidence of the third trochanter varies from 17–72% between ethnic groups and it is frequently reported as more common in females than in males. Lower part
The lower extremity of the femur (or distal extremity) is the thickest femoral extremity, the upper extremity is the shortest femoral extremity. It is somewhat cuboid in form, but its transverse diameter is greater than its antero-posterior (front to back). It consists of two oblong eminences known as the condyles.Anteriorly, the condyles are slightly prominent and are separated by a smooth shallow articular depression called the patellar surface. Posteriorly, they project considerably and a deep notch, the Intercondylar fossa of femur, is present between them. The lateral condyle is the more prominent and is the broader both in its antero-posterior and transverse diameters. The medial condyle is the longer and, when the femur is held with its body perpendicular, projects to a lower level. When, however, the femur is in its natural oblique position the lower surfaces of the two condyles lie practically in the same horizontal plane. The condyles are not quite parallel with one another; the long axis of the lateral is almost directly antero-posterior, but that of the medial runs backward and medialward. Their opposed surfaces are small, rough, and concave, and form the walls of the intercondyloid fossa. This fossa is limited above by a ridge, the intercondyloid line, and below by the central part of the posterior margin of the patellar surface.
