Te gas is produced from the surrounding sof tissues, and its accumulation mechanism is poorly understood. Osteonecrosis of the vertebral end plates with negative pressure between the bone fragments is mandatory to release gas from the surrounding tissue, a situation that can be clas- sically seen in osteoporotic vertebral fractures and collapse. Vacuum phenomenon is also seen in osteonecrosis due to long-term corticosteroid therapy, diabetes mellitus, arterio- sclerosis, multiple myeloma, and alcoholism. T e main diferential diagnosis of the intravertebral vac- uum phenomenon is gas produced by osteomyelitis and malignancies. In infectious gaseous production, the gas has high pressure and tends to accumulate in small collections, plus extends into the adjacent sof tissues, which is not seen in vacuum phenomenon where gas is limited to the bony or intradiskal areas. Kümmel’s disease is a term used to describe vacuum phe- nomenon within a vertebra that arises from vertebral end plates osteonecrosis and vertebral collapse. Kümmel’s disease represents healing failure of an osteoporotic vertebral frac- ture with the formation of pseudoarthrosis (false joint). Normally, the cortex in the mid-shaft of the second metacarpal should be almost one third the thickness of the metacarpal width. It is typically seen as long lucent lines parallel to the long axis of the bone (.

The middle colic artery generally divides early in its course into right and left branches. The left branch forms a well-developed marginal artery that connects with the left colic artery at the splenic ﬂexure. When the proximal half of the transverse colon is removed, the left colic connec- tion of this marginal artery supplies the remaining transverse colon. Documentation Basics This is all done before there is any manipulation of the tumor—hence the “no-touch” technique. The specimen may • Findings now be removed by the traditional method of incising the peritoneum in the right paracolic gutter and elevating the right colon. Operative Technique (Right and Transverse When right colon resection is performed for benign Colectomy) disease, extensive mesenteric resection is not required and a lateral to medial approach may be utilized.

This is more commonly seen in European countries and in Japan order generic mildronate pills symptoms 6 year molars, but a rare occurrence in Chinese and Negro races probably due to the fact that the latters carry their babies on their backs with the hips abducted buy mildronate 500 mg on-line 247 medications. The earlier the diagnosis is made, the easier will be the treatment and more will be the chance of cure. Extra skin crease along the medial aspect of the thigh in unilateral case and widening of the perineum in bilateral case will be noticed by an observant mother. Lastly delayed walking and a limp when the child begins to walk should arouse suspicion of this condition. In bilateral cases typical waddling gait may be missed by the clinician but will not be missed by an observant mother. Movements are painless, but abduction and rotations are limited in completely dislocated hip. Unlike the previous condition the boys are more affected by this condition and about 4 times commoner than the girls. In the beginning, when the joint becomes rather irritable, more or less all movements are slightly restricted. Later on in the established stage there is limitation of abduction and internal rotation. Muscular wasting of the limb becomes obvious and there may be moderate flexion and adduction deformity. The diagnosis cannot be confirmed without skiagraphy, the findings of which have been discussed in the earlier section. There may be a history of trauma in which case this condition suddenly appears, otherwise the majority of cases are gradual in onset. The earliest symptom is a painful limp and pain may be referred to the knee joint. Continued weight bearing will lead to more pain and limp with shortening and external rotation of the limb. On examination the greater trochanter is higher and more posteriorly placed than the unaffected side. The hip joint is second only to the vertebral column so far as the sites of tuberculosis of the bones and the joints are concerned. The earliest sign is the limp, which in the beginning comes on after the patient has walked some distance. Pain is probably the first symptom which is more often referred to the thigh or Fig. The general signs and symptoms such as malaise, pallor, loss of weight, evening rise of temperature, night sweat etc. On examination, the characteristic deformities of different stages have already been discussed in details under the heading of "attitude". A child with high pyrexia, a limp, pain in the hip with redness and brawny oedematous swelling, should be considered as suffering from acute suppurative arthritis. Diagnosis is confirmed by aspirating the hip joint with a needle under anaesthesia. There will be slight wasting, but the cardinal sign is the limitation of all movements at their extremes. The patient is immediately put to bed and a skin traction is applied to the affected leg. Investigations like examination of the blood and X-ray are essential to come to a diagnosis. The symptoms may mimic acute suppurative arthritis, but absence of toxaemia, high pyrexia, localized redness and oedema will differentiate this condition from acute suppurative arthritis. The inflammatory process leads to destruction of the head and neck of the femur and pathological dislocation may result from it. Besides these infective destructive lesions, spastic paralysis, poliomyelitis may also lead to pathological dislocation of the hip. Pain is the usual presenting symptom which is of boring character, mainly localized to the hip but may be referred to the knee joint. In the beginning the pain is complained of when movement follows a period of rest, later on it is more constant and disturbing. Limp may be noticed early, but more often than not it comes later than pain and stiffness. The limp is due to either pain or stiffness or apparent shortening due to adductor spasm. Some limitation of all movements is detectable but abduction, extension and medial rotation are restricted early. The bone becomes sclerosed with lipping and osteophytes at the margins of the joint. The patient is first examined in the standing position both from front and behind, secondly in the seated position, thirdly in the supine position and lastly in the prone position. During these examinations the hip is also examined, as very often a patient with the pathology in the hip will complain of pain in the knee. In case of locking the patient fails to extend the joint beyond a certain angle and the knee is kept in flexed position f ■ » A w i t h limping. This condition may be confused with superficial r cellulitis, but the latter will Fig. Extra-articular swellings are quite common l * H around the knee due to enlargement of the different bursae around the joint. The semimembranosus bursa is seen behind the knee on its medial aspect and slightly above the joint line. Infrapatellar bursa (lying deep to the ligamentum patellae), bicipital bursa (lying under the biceps tendon) may occasionally be enlarged. The suprapatellar bursa almost always communicates with the knee joint and becomes swollen in effusion of the joint. This condition also gives rise to a swelling on the posterior aspect of the knee joint in its middle and becomes prominent on extension and disappears on flexion of the joint. This condition is often associated with tuberculosis or osteoarthritis of the joint. But in affections of the knee joint if there be any muscular wasting, it is more obvious in the thigh. So far as the effusion of the joint is concerned, two important tests may be performed — fluctuation and "patellar tap". Fluctuation is demonstrated by pressing the --------- suprapatellar pouch with one hand and feeling the impulse with the thumb and the fingers of the other hand placed on either side of the patella or the ligamentum patellae. With the index finger of other hand the patella is pushed backwards towards the femoral condyles with a sharp and jerky movement.
