Note: Fractures of the bilateral pedicles and associated small paraspinal hematoma (arrows) causes for erectile dysfunction and its symptoms purchase 100 mg zudena with visa. C1 Fracture Description: Three primary types of fractures have been identified involving the C1 vertebrae: (1) the posterior arch fracture usually occurs at the junction of the posterior arch and the lateral mass; (2) the lateral mass fracture usually occurs unilaterally with the fracture line passing either through the articular surface or just anterior and posterior to the lateral mass on one side; and (3) the burst fracture (Jefferson fracture) is characterized by four fractures impotence bicycle seat cheap 100mg zudena with visa, two in the anterior arch and two in the posterior arch impotence of organic origin discount 100mg zudena mastercard. This fracture may present as a stable nondisplaced fracture with no encroachment on the spinal cord or as a displaced fracture with varying degrees of encroachment on the spinal cord. The degree of injury depends on the magnitude of the axial loading and whether the spine is in flexion, neutral, or an extension position. Epidemiology: Trauma to the spine occurs more commonly in the cervical region than in any other area of the spine. Signs and Symptoms: the patient may present with pain or a varying degree of paralysis. May demonstrate other related bony or soft tissue injuries to the upper cervical region. Treatment: Most fractures of the C1 vertebrae can be treated with immobilization (e. Cervical Facet Lock Description: A dislocation of the zygapophyseal or facet joint of the cervical spine. A facet lock (dislocation or subluxation) occurs when the inferior articulating process (facet) of the superior vertebra is locked in front of the superior articulating process (facet) of the inferior vertebra. The position of the head and neck at the time of impact and the direction of the force are key factors in this type of injury. Epidemiology: Unilateral facet injuries represent 6% to 10% of all cervical spine injuries. Bilateral facet dislocations are frequently associated with neurological deficits. Axial image shows normal relationship of the inferior and superior facets as the “hamburger on a bun” sign. Treatment: For unilateral facet dislocation, surgical treatment (open reduction) with internal fixation is more successful than closed reduction traction with a halo vest. Prognosis: Surgical treatment results in reduced treatment failure, reduced pain, and neurological deterioration as compared to nonsurgical treatment.

Vertebral Compression Fracture Description: Compression fractures of the lumbar spine occur as a result of a combination of flexion and axial loading (compression) of the vertebrae. Etiology: This fracture can occur as a result of trauma, metastatic disease to the spine, or osteoporosis. Epidemiology: Compression fractures are common in the aging and geriatric patients with osteoporosis. Signs and Symptoms: Patient presents with back pain and possible neurologic deficit. Treatment: These injuries are usually stable because the bony posterior elements and longitudinal ligaments are intact. Prognosis: Depends on the extent of the injury and status of the spinal canal and cord. Spinal Cord Hematoma Description: A spinal cord hematoma is a collection of blood in the spinal cord, most commonly due to trauma. Etiology: Most spinal cord hematomas occur as a result of trauma to the spinal cord, ligamentous structures, and/or bony vertebra. Other associated causes may include an acute herniated disk or hemorrhage from an arteriovenous malformation. Epidemiology: Trauma to the spinal column occurs at an incidence of approximately 2 to 5 per 100,000 population. Less frequent causes include falls, diving accidents, and sports and recreational injuries.

Longitudinal color Doppler image of the proximal patella tendon demonstrating severe tendinosis with marked hyperemia erectile dysfunction jet lag zudena 100 mg for sale. Other pathologic processes may mimic prepatellar bursitis and judicious use of medical imaging including ultrasound erectile dysfunction morning wood buy generic zudena 100mg on-line, magnetic resonance imaging erectile dysfunction treatment with homeopathy purchase 100 mg zudena with mastercard, plain radiography, and computed tomography may help clarify the diagnosis (Figs. Given that bursitis is usually the result of either trauma or abnormal function of the affected joint, one should assume that additional pathology other than the bursitis being treated is present. Sagittal proton density (A) and fat-suppressed T2-weighted (B) magnetic resonance images through the knee show an ovoid mass of fat signal intensity within the Hoffa fat pad (arrows). The fatty nature of this intra-articular mass confirms the diagnosis of synovial lipoma.

B: Lateral view of the right knee with evidence of a calcified mass anterior to the proximal tibia. Axial T2-weighted magnetic resonance images of prepatellar bursitis (A) and superficial infrapatellar bursitis (B). Periarticular lesions detected on magnetic resonance imaging: prevalence in knees with and without symptoms. The deep infrapatellar bursa lies between the anterior subcutaneous tissues of the knee and the anterior surface of the patellar tendon (Fig. The bursa serves to cushion and facilitate sliding of the skin and subcutaneous tissues of the anterior inferior portion of the knee over the tibia. The deep infrapatellar bursa is held in place by patellar tendon which is an extension of the common tendon of the quadriceps tendon (Fig. Both the quadriceps tendon and its expansions as well as the patellar tendon and the deep infrapatellar bursa are subject to the development of inflammation caused by overuse, misuse, or direct trauma. The quadriceps tendon is made up of fibers from the four muscles that comprise the quadriceps muscle: the vastus lateralis, the vastus intermedius, the vastus medialis, and the rectus femoris (Fig. The tendons of these muscles converge and unite to form a single, exceedingly strong tendon. The patella functions as a sesamoid bone within the quadriceps tendon, with fibers of the tendon expanding around the patella and forming the medial and lateral patella retinacula, which help strengthen the knee joint. These fibers are called expansions and are subject to strain; the tendon proper is subject to the development of tendinitis. The deep infrapatellar and prepatellar bursae also may concurrently become inflamed with dysfunction of the quadriceps tendon. The deep infrapatellar bursa is held in place by patellar tendon which is an extension of the common tendon of the quadriceps tendon. The quadriceps tendon is made up of fibers from the four muscles that comprise the quadriceps muscle: the vastus lateralis, the vastus intermedius, the vastus medialis, and the rectus femoris. The bursa serves to cushion and facilitate sliding of the patellar tendon over the tibia. The bursa is subject to inflammation from a variety of causes with acute trauma to the knee and repetitive microtrauma being the most common. Acute injuries to the bursa can occur from direct blunt trauma to the anterior knee from falls onto the knee as well as from overuse injuries including running on uneven or soft surfaces or 937 jobs that require kneeling or crawling on the knees like carpet laying and scrubbing floors. If the inflammation of the bursa is not treated and the condition becomes chronic, calcification of the bursa with further functional disability may occur (Fig. Gout and other crystal arthropathies may also precipitate acute deep infrapatellar bursitis as may bacterial, tubercular, or fungal infections.
