Knee Exam
Knee Exam Scott 23,850 Views • 3 years ago

The Knee Exam
Observation:
1. Make sure that both knees are fully exposed. The patient should be in either a gown or shorts. Rolled up pant legs do not provide good exposure!
2. Watch the patient walk. Do they limp or appear to be in pain? When standing, is there evidence of bowing (varus) or knock-kneed (valgus) deformity? There is a predilection for degenerative joint disease to affect the medical aspect of the knee, a common cause of bowing. Varus Knee Deformity, more marked on the left leg. 3. Make note of any scars or asymmetry. Chronic/progressive damage, as in degenerative joint disease, may lead to abnormal contours and appearance. Is there obvious swelling as would occur in an effusion? Redness suggesting inflammation? 4. Is there evidence of atrophy of the quadriceps, hamstring, or calf muscle groups? Knee problems/pain can limit the use of the affected leg, leading to wasting of the muscles.

While both legs have well developed musculature,
the left calf and hamstring are bulkier than the right. 5. Look at the external anatomy, noting structures above and below the knee itself: 1. Patella 2. Patellar tendon 3. Quadriceps/Hamstring/Calf muscles 4. Medial and lateral joint lines. 5. Femur and Tibia 6. Tibial tuberosity


Ballotment (helpful if the effusion is large) 1. Slightly flex the knee which is to be examined.
2. Place one hand on the supra-pateallar pouch, which is above the patella and communicates with the joint space. Gently push down and towards the patella, forcing any fluid to accumulate in the central part of the joint.
3. Gently push down on the patella with your thumb.
4. If there is a sizable effusion, the patella will feel as if it's floating and "bounce" back up when pushed down.

Normal Heart Sounds
Normal Heart Sounds Scott 67,412 Views • 3 years ago

Normal Heart Sounds With the aid of a stethoscope you can hear the characteristic sounds of the normal heartbeat, typically described as a "lub-dub." These sounds are produced by the closure of the heart valves. The first heart sound or "lub" results from closure of the tricuspid and mitral valves. It is a rather low-pitched and a relatively long sound which, as indicated in, represents the beginning of ventricular systole. The second heart sound, or "dub," marks the beginning of ventricular diastole. It is produced by closure of the aortic and pulmonary (pulmonic) semilunar vanes when the intraventricular pressure begins to fall. This "dub" sound is typically heard as a sharp snap because the semilunar valves tend to close much more rapidly than the AV valves. Because diastole occupies more time than systole, a brief pause occurs after the second heart sound when the heart is beating at a normal rate. Therefore, the pattern that one hears is one of: "lub-dub" pause, "lub-dub" pause, and so on. Sometimes, especially in young normal individuals, a third heart sound can be heard. This sound is produced by the very rapid influx of blood into the partially filled ventricle. It is typically very faint and as such difficult to hear.

Nerve Monitoring After Transoral Endoscopic Thyroid Resection
Nerve Monitoring After Transoral Endoscopic Thyroid Resection DrHouse 13,354 Views • 3 years ago

Background: The number of patients demanding endoscopic neck surgery is rising. The access trauma of the axillary, breast and chest approaches is bigger than in open or video assisted surgery. We tested the feasibility of he sublingual transoral access which is in our opinion the only real minimally...-invasive extracollar endoscopic access to the thyroid gland Methods: We performed an experimental investigation in a porcine model. In 10 pigs we made 10 endoscopic transoral thyroidectomys with a modified axilloscope with the help of ultrasonic scissors and a neuro-monitoring system for identification of the recurrent laryngeal nerve. Results: The average operation time from the introduction to the removal of the obturator just above the larynx was 57 seconds. The mean operation time was 43 minutes. With the help of the neuro-monitoring system we proved in all cases the function of the recurrent laryngeal nerve on both sides. The pigs were observed for another two hours after operation. During and after the operation no complications appeared. Conclusions: We could show that the endoscopic transoral thyroid resection in pigs is possible and save. Our results might be useful for using this access for endoscopic thyroid resection in humans.

The trypan blue-stained viscoelastic is removed in its entirety using a Simcoe cannula. A stream of Healonid GV can be seen flowing into the cannula with some residual viscoelastic remaning, which is subsequently removed. Without the dye, much of the viscoelastic might have been left in the anterior... chamber – a risk factor for an acute rise in intra ocular pressure.
