Beagle dog 7 years old, entire male (same dog as in all projections of thorax to highlight respiratory system, Figures 404, 411 and 414). The right lateral recumbent projection has been included in this section to illustrate the subtle but denite difference of the right and left recumbencies. Notice the obvious diaphragmatic shadow changes but also the more obvious oesophageal uid in the right lateral and the pleural ssure line seen in the left lateral (labelled (6) on line drawing Figure 406). Both left and right recumbent laterals should be performed for full evaluation of lung tissue. Radiographic changes in the more recumbent lobes can easily be overlooked or even be not evident on one recumbent projection. As rotation is present in both of these projections the cardiac shadow cannot be critically analysed but as a routine the right lateral recumbency is superior for cardiac shadow evaluation. If lung pathology is suspected in one hemithorax, radiography must ensure that in the lateral projection that hemithorax is uppermost. To perform both recumbencies may prove impractical if respiratory distress is severe. Figure 410 Line drawing of photograph representing radiographic positioning for Figure 411.

Extends beyond 5 Thickened, brotic, pleural tissue at caudal border of right the 1st. Skin folds are distinguished from thoracic cavity structures by following their continuous shadows beyond the 8Tracheal lumen within the cranial mediastinum just right cavity limits. Beagle Dog 7 years old, entire male (same dog as in all projections of thorax to high light respiratory system, Figures 404, 408 and 411). The dorsoventral projection has been included in this section to show that even with fully inated lungs, the area of lung exposed is less in this projection compared with the ventrodorsal. This effect is smaller in the cat but with this species the thoracic cavity is greatly reduced, and appears more triangular, when the front limbs are not extended forwards. The dorsoventral projection should always be used for cardiovascular evaluation as cardiac position is not altered. It must also be remembered that the ventrodorsal and/or dorsoventral projection(s) should be performed rst, before the recumbent lateral projections. Hypostatic congestion/lung lobe collapse occurs rapidly in recumbent animals suffering from cardiovascular or respiratory problems. Even in clinically normal animals hypostatic congestion will develop during lateral recumbency (see Figure 432).

Ligament is a brous 1R ight border of cranial vena cava thickening in the ventral portion of the caudal 2 Left border of left subclavian artery mediastinum. Thoracic portion lies slightly to the right 10 Diaphragmatic shadow until its termination when it is midline. As dog ages, lymphoid tissue reduces but in older dogs a vestigial thymus is often seen (B). Radiograph taken during general anaesthesia with endotracheal tube removed for clarity of radiographic shadows. The radiograph shows the vertical position of the hyoid bones together with a much reduced oropharynx and very large soft palate shadow. The nasopharynx is also small and the endotracheal intubation has caused the epiglottis (closed arrow) to lie ventrocranially. On recovery from the general anaesthetic, when swallowing reexes return, the epiglottis will rotate dorsocranially and come to rest just ventrocranially to the soft palate. Note the large retropharyngeal space (open arrow) which is normal in this type of breed but does create an apparent ventral displacement of the laryngeal cartilages. An Atlas of Interpretative Radiographic Anatomy of the Dog and Cat 293 Dog – Thorax Figure 425 Right lateral recumbent projection of thorax. Samoyed dog 6 years old, entire female (same dog as in Figure 427) the radiograph demonstrates the rounded cardiac shadow, with increase in sternal contact, caused by the horizontal position of the heart within the thoracic cavity. Cardiac measurements, when compared to a normal or intermediate chested breed of dog, are greater in the craniocaudal direction. The comparatively large craniocaudal measurement together with rounding of cranial cardiac border and increase in sternal contact must not be misdiagnosed as right-sided cardiac enlargement (atrial and ventricular). The lung opacities in this dog are due to ‘age’ changes within the bronchial walls and interstitial tissue (see Figure 433 for ‘age’ changes). This is caused by the position of the heart within the thoracic cavity being almost perpendicular to the thoracic spine. Cardiac measurements, compared to a normal or intermediate chested breed of dog, are less in the craniocaudal direction and greater in the dorsoventral direction. Care must be taken when analysing this type of cardiac shadow as the upright appearance, especially of the caudal border, may be misdiagnosed as left-sided cardiac enlargement. An Atlas of Interpretative Radiographic Anatomy of the Dog and Cat 295 Dog – Thorax Figure 427 Dorsoventral projection of thorax. The radiograph shows the rounded left and right cardiac borders seen in this type of chested breed of dog. Rounded cardiac apex is more left of the midline compared to the normal or intermediate chested breed of dog. The apical level is due to the oblique position of the heart across the thoracic cavity’s midline. As with the right lateral recumbent projection of thorax, the appearance of the cardiac shadow in the short, barrel chested breed of dog must not be confused with right-sided cardiac enlargement (atrial and ventricular). Also note the fat deposition mimicking a wide cranial mediastinum and right-sided cardiac enlargement (see fat deposition within thoracic cavity, Figure 435). The radiograph shows the short-rounded appearance of the cardiac shadow typical in this type of chested dog.

The majority of deaths after hip fracture are due to how soon after hiv infection symptoms effective 100 mg mebendazole pre existing comorbidity antiviral yiyecekler buy 100 mg mebendazole free shipping, such as ischemic heart disease hiv infection early warning signs purchase mebendazole 100mg on-line, with the majority a direct result of 18 complications or management of the fracture itself hiv infection treatment guidelines purchase generic mebendazole line. There is an exponential increase in hip fracture with aging due to and age-related 18 increase in the risk of falling and reduction in bone strength. Hip fractures are more frequent among Caucasians than among non-Caucasians and is explained by the higher bone 18 mass observed in African Americans compared to Caucasians. Hip fractures are seasonal, occurring more frequently in both sexes during the winter in temperate countries. The age 18 adjusted male to female incidence ratio for hip fracture is about 1:2. Women have an expected longer lifetime longevity and approximately 80% of hip fractures occur in 211 18 women. Approximately 18 20% of the total health care costs of osteoporosis can be attributed to fracture in men. Chronic Hip Pain & Insufficiency 19 Adult chronic hip pain may elude clinicians both clinically and radiographically. Subtle radiographic signs have been documented that indicate traumatic, infectious, arthritic, neoplastic, congenital, or other causes. For example, stress fractures appear 19 as a lucent line surrounded by sclerosis or as subtle lucency. Subtle femoral neck angulation, trabecular angulation, or a subcapital impaction line indicates an 19 insufficiency fracture. Effusion, cartilage loss, and cortical bone destruction are diagnostic of a septic 19 19 hip. Rheumatoid arthritis may manifest as classic osteopenia, uniform cartilage loss, and erosive change. Osteoarthritis may result in cyst formation, small osteophytes or buttressing of the femoral neck. Magnetic resonance imaging has been used to evaluate a variety of hip 20 disorders, particularly the evaluation of avascular necrosis. Glucocorticoid therapy can cause aseptic (avacsular) necrosis, most commonly in the femoral neck, distal femur, and proximal humerus and is dose dependent. Occupational and Sports Related Risk Factors Sports injuries are a frequent reason for radiography examinations of the lower extremity. Radiographers should be familiar with some of the more common sport injuries to the lower leg in order to produce the highest quality images possible. Often patients who havea sports related injury to the lower extremity might not seek medical 212 attention immediately. Some of the warning signs that a sports injury may require immediate medical intervention includes when the victim: Has severe pain in the front of the leg that does not disappear when the sport or exercise stops; Hears a pop just above the heel and is unable to rise onto the toes; and, Has pain, swelling, and redness in the upper calf. Several risk factors that have been linked to the incidence of musculoskeletal injuries include repetitive exertions, forceful exertions, and awkward postures. Repetitive exertions have been identified as one of the leading risk factors for upper extremity cumulative trauma disorders. The repetitiveness of a task or operation can be described in several ways including: 1) the number of cycles per hour, 2) the number of lifts per hour, 3) the number of steps (exertions) included in each work cycle, or 4) the total number of exertions per hour. Forceful exertions performed by the upper extremities in a hand-intensive task or by the whole body are associated with the development of musculoskeletal injuries. The force requirements of an activity are related to the weight of the object lifted or carried, the slipperiness of objects being gripped, and other manual reaction forces such as torque. The pace of the activity, the use of gloves, and hand posture has been shown to increase the force requirements to perform an activity. Awkward postures of the upper extremities and torso have also been identified by researchers and linked to the incidence of musculoskeletal disorders. Standing erect with the arms hanging at the side is considered to be a non-stressful posture. The knee is a hinge joint with a range of motion of 0 degrees in full extension to 17 130 degrees of full flexion. Dislocation of the knee is considered an emergency due to the high rate of associated vascular and nerve damage. Patellar dislocations are more 17 common in females than males because of the increased femorotibial angle in females. The patient presents with posterior knee pain and may walk with the knee flexed slightly. The patient may report hearing a “pop” at the time of the injury followed by severe instability of the joint. The patient may also present with varying degrees of pain and report immediate swelling. The menisci are two areas of semilunar cartilage in the capsule of the knee joint. Their purpose is to act as shock absorbers, lubricate the joint, and they serve to evenly distribute weight to the femoral condyles and the tibial plateau. The patient presents with tenderness of the medial or lateral joint line with delayed swelling. Ankle dislocations are almost always accompanied by fractures of both the medial and lateral malleoli. Ankle dislocations often result from falls on uneven surfaces or twisting motions. There are four classifications of ankle dislocations; posterior, anterior, upward, and lateral. In the case of a contusion caused by a direct kick, if the kick occurs directly over a bone, the bone usually will not fracture but causes bleeding under the bone. Swelling lifts nerve endings away from the bone, thus extreme tenderness and pain. Compression on the area, elevation of the limb, and application of ice are often recommended to reduce swelling. Tennis leg typically occurs in those who play tennis, however, this injury may occur in hikers and in team sports such as baseball, football, basketball, soccer, racquetball, handball, and participants in any running sports that demand quick thrusts and sudden changes of direction. All of these sport activities may result in tennis leg, especially in people between the ages of 30 and 45 years of age. It is actually the ripping away of the part of the calf muscle from the Achilles tendon. Generally, the patient with tennis leg will recall their symptoms as sudden pain and maybe a popping sound. They may explain that they were able to continue doing what they had been doing for a while, because about 75% of the calf muscle are still attached to the Achilles tendon. Eventually, the muscles go into a spasm, contracting violently, and the foot begins to point downward. The tender area in the calf region marks the point where the muscle fibers flow into tendon fibers. Doctors advise patients with tennis leg to stretch right away to help bring the foot back to neutral. The motion stretches out the gastrocnemius muscle and provides internal compression for the injured part, slowing the blood rush to the area, thus reducing swelling. Eventually the muscle reattaches to the tendon, not in the same attachment position and usually a little shorter than it was originally. Patellar tendinitis or jumper’s knee is a common sports injury to high jumpers, basketball and volleyball players, dancers, runners, and anyone who runs and jumps in their sport. In acute patellar tendinitis, the bottom of the kneecap swells and there is difficulty in moving the patella. Osgood-Schlatter disease is not really a disease but rather a form of tendinitis at the lower end of the patellar tendon where it goes into the shinbone. This is a common condition in adolescents because when their bone grows it doesn’t stretch like elastic; rather it expands at certain spots near the upper and lower ends of bone at the growth centers. It is at this growth center where new bone is made, pushing out to lengthen and thicken the existing bone. When a tendon strains against a bone’s growth center, it can pull away pieces of soft, forming bone, as in Osgood-Schlatter disease. Because the patellar tendon is so near the skin, it may get red, swollen, and very tender.

Traction on the femoral head is essen anterior column is „high“ on the greater sciatic tial in obtaining a reduction antiviral youtube order mebendazole 100 mg line. Special clamps and the ball spike pusher to antiviral kleenex side effects cheap 100 mg mebendazole free shipping help with reduction in the acetabulum. Note also the ball spike pusher, which is invaluable in reducing small fragments of the acetabular wall and for pushing on the iliac crest. A both-column acetabular fracture (a) was reduced and xed with a double-loop cerclage wire from the greater sciatic notch to a point just cephalad to the anterior inferior spine (b). The technique of insertion of the wires is as follows: c Both the medial and lateral aspects of the ilium are exposed to the greater sciatic notch. One exposure, usually the medial one, must be large; the opposite one may be small. The fracture must be reduced temporarily with clamps to safely pass the wire, in this case on a long, right-angled (Mixter) clamp. The approach in this case is the ilioinguinal one but modied to allow lateral exposure of the greater sciatic notch. The plates may be applied to the anterior column from the inner table of the Implants: Screws ilium to the symphysis pubis (. Screws are essential, especially when fixing smaller frag within the joint are a not uncommon cause of chon ments. For fixation of the plate to the bone, fully threaded cancellous screws are desirable, the 6. These plates Kirschner wires, or cerclage wires, screw fixation can be molded in two planes and around the difficult of the fractures is essential. In large individuals, and in pelvic fixa interfragmental lag screws, plates may be used to tion, the 4. In the acetabulum, where anatomic reduction of the intra-articular fragments is essential, the use of newer minimally invasive techniques is lim ited. The posterior column in this area is extremely thin, and misdirected screws will commonly pen etrate the hip joint. No screws should be placed in this area unless absolutely essential, and then only if directed away from the articular surface. Note that no screws are used in the central posterior portion of the acetabulum to avoid penetration of the articular surface. The most distally placed screw xes the plate to the ischial tuberosity, best seen in d. After reduction of the fracture, Kirschner wires are used for provisional xation. This will allow the sur geon to carefully plan the position of the interfragmental screws and the neutraliza tion plate along the posterior column (b). If the plate is not contoured properly, a fracture that appears reduced posteriorly may in fact be malreduced anteriorly (a). The postoperative care depends upon the ability of If there is concern about the quality of the bone, the surgeon to achieve stable internal fixation, which about gross comminution, especially of the medial in turn depends on the quality of the bone and the wall of the acetabulum, or about inadequate stability, adequacy of the reduction. In general, we maintain traction should be continued for 6 weeks until some skeletal traction and continuous passive motion healing of the fragments has occurred. If stability is deemed to be excellent, the Indocid (25 mg tid) is used to prevent heterotopic traction may be removed and the patient ambulated. Low-molecular-weight heparin or cou Weight bearing is not started until some signs of madin is used in addition to prevent thromboem union are present, usually by the sixth postoperative bolic disease. Avascular necrosis of the femoral head is a devas Complications associated with acetabular fractures tating complication, developing in 6. It was only seen tions include thromboembolic disease, wound necro in the posterior types in our series, and was 18% in sis, and sepsis. Avascular necrosis of the acetabular seg nerve injuries, avascular necrosis, and chondrolysis, ments may also occur, causing collapse of the joint. Chondrolysis following acetabular fractures can occur with or without surgical intervention. In our first 102 cases, there were 22 sciatic nerve lesions, 16 post At some centers (Mears 2003; Tile 2003) where con traumatic and six postoperative. The technical difficulties by the spike of the anterior column or during sur of securing good fixation of the acetabulum should gery using an ilioinguinal approach. We have seen not be underestimated; this also requires consider one patient with a post-traumatic femoral artery able experience. A nerve cable graft was performed with as a bone graft and inserting an uncemented cup poor results, that is, no quadriceps function was with screws or a roof ring with screws and cement is restored. Other techniques is situated in a vulnerable position in the greater include the use of cerclage wires (see. The lateral cutaneous nerve of the thigh is commonly injured in iliofemoral or ilioinguinal approaches. Our knowledge of acetabular trauma has advanced Heterotopic ossification is a major postopera considerably since the first edition of this book. Also, most large lateral extensile approaches of the hip which strip metropolitan areas in the developed world have the gluteus medius from the lateral iliac crest. Moed pelvic-acetabular referral centers with expert care and Maxey (1993), McLaren (1990), and others have available. The general orthopedic or trauma surgeon reported on the efficacy of Indocid, although this has needs to resuscitate the patient with acute trauma 13. In obese patients, the contralateral thigh gets in the way of the surgeon’s hand, and prevents correct placement of the guidewire. During placement of the anterior column guidewire, the femoral nerve, artery and vein are at risk. The sciatic nerve and all the structures that exit the greater sciatic notch are at risk. Hip exion relaxes the sciatic nerve, and draws it away from the starting point at the ischial tuberosity. The iliac oblique view is used to ensure that the guidewire remains posterior to the acetabulum and does not enter the greater sciatic notch. The surgeon must all joint trauma) reflects the damage to the articular ask the question: Can I fix the fracture, can anybody Straightforward fractures such as in a posterior wall Furthermore, avascular necrosis and other complica or a posterior column fracture can be handled by tions may compromise the end result. Unfortunately, these surgeon who undertakes the operation must obtain simple fractures may be complicated by marginal an anatomical reduction and stable fixation for any impaction or comminution and may lead to poor chance of an improved result. If the fractures are comminuted and com use all the described modalities to prevent the com plex (type B or C), referral to an expert center is plications that occur frequently. Referral should be prompt Finally, the role of immediate total hip arthroplasty to allow early investigation and surgery to be per is being clarified, especially for the older patient with formed, which will help with anatomical reduction. In older patients with a both-column more complex injuries, further courses and prefer (Type C) fracture with secondary congruence, a more ably fellowship training are important. The prog option if the patient develops late pain from avascu nosis depends on the original injury, which (as in lar necrosis or osteoarthritis. This 65-year-old man sustained a fall while skiing and provoked a posterior wall fracture. During the acute total hip arthroplasty, a structural autograft of femoral head was used to restore the acetabular defect.
