Pronounced soft-tissue swelling may be followed by bone destruction cheap 160 mg super viagra free shipping, deformity purchase 160mg super viagra visa, and fistula formation generic super viagra 160mg. In acropachy thyroid acropachy, a rare complication of hyper- thyroid disease that develops after thyroidectomy or radioactive iodine treatment of primary hyper- thyroidism. There is typically a generalized and symmetric spiculated periosteal reaction that primarily involves the midportion of the diaphyses of tubular bones of the hands and feet. Dilantin therapy The percentage of patients with abnormally thick- ened heel pads increases steadily with the length of treatment. Dilantin may also cause calvarial thickening that can be confused with acromegaly. Usually involves the junction of the middle and lower thirds of the tibia or fibula (or both) during the first year of life. An abnormally formed, deficient, or gracile fibula is a frequent accompaniment of pseudoarthrosis of the tibia. Nonunion of a fracture A false joint may form at the fracture site, with one (Fig B 29-2) fragment presenting a convex surface that fits into the concave surface of the apposing fragment. Although there is osteoporosis of the bones of the ankle and the ribbon-like extensive callus formation, the lucent fracture line can still be shape of the lower fibula. Although fracture healing is often normal, exube- rant callus formation and bizarre deformities (in- cluding pseudoarthrosis) may occur. Fibrous dysplasia Proliferation of fibrous tissue in the medullary cavity causes local expansion of bone and cortical erosion from within, predisposing to pathologic fractures that may lead to pseudoarthrosis. In severe and long-standing disease, affected bones may be bowed or deformed (eg, shepherd’s crook deformity of the femur). Congenital pseudoarthrosis Rare condition that is generally unilateral, prima- rily involves the tibia, and develops during the first or second year of life. Initially, there is anterior bowing of the lower half of the tibia with sclerosis, narrowing of the medullary canal, and cystic abnormalities at the apex of the curve indicating impending fracture and pseudoarthrosis. Once the fracture appears, the margins of adjacent bone become increasingly tapered. Congenital pseudoarthrosis of the clavicle occurs almost exclusively on the right (bilateral in 10% of patients) and presents within the first few months of life as a painless lump over the medial third of the clavicle. Radiographs show the medial end of the clavicle superior to the lateral end, osseous discontinuity, and the absence of callus formation (absence of pain and visible callus per- mits differentiation from post-traumatic pseudoar- throsis). There is diffuse loss of the interosseous space and an eroded and often diminutive femoral head. Rheumatoid variants Ankylosing spondylitis; psoriatic arthritis; reactive arthritis syndrome; inflammatory bowel disease. Acquired softening of bone Paget’s disease; osteomalacia or rickets; hyperpa- rathyroidism. Osteoarthritis Usually a mild degree of protrusion that is typically associated with medial migration of the femoral head. May be primary or secondary to hemophilia, pseudogout, hemochromatosis, or ochronosis. Post-traumatic May develop after an acetabular fracture with medial dislocation of the hip or after total hip replacement arthroplasty with marked thinning of the available acetabular roof. Osteogenesis imperfecta Caused by the osteoporotic and abnormally fragile bone in this inherited disorder of connective tissue. Primary acetabular Usually bilateral and much more frequent in protrusion (Otto pelvis) women. Associated loss of the joint space usually (Fig B 30-2) results in axial or medial migration of the femoral head with respect to the acetabulum. Although the etiology is unknown, postulated causes include failure of ossification or premature fusion of the Y cartilage or a direct consequence of normal stress on the Y cartilage (normally, the protrusion is reversible due to diminished stress after age 8; failure of correction of the protrusion resulting in its persistence into adult life may be due to pre- mature fusion and coxa vara). Miscellaneous causes Destruction of the acetabulum resulting from septic arthritis, neoplasm, or radiation therapy. The peak (Fig B 31-1) incidence is between 6 and 24 months of age (children less than 6 months may still have the protection of their fetal hemoglobin). Differentia- tion from osteomyelitis is difficult both clinically and radiographically, though the lack of systemic symptoms and fever suggests infarction without osteomyelitis. Pyogenic osteomyelitis Most commonly represents Salmonella infection in a child with sickle cell anemia. May be extremely difficult to differentiate from the hand-foot syndrome in this condition. Tuberculosis Most often occurs in children, in whom it may be (“spina ventosa”) multiple. Sequestrum formation is uncommon, (Fig B 31-2) though it may be associated with small sinus tracts through which bony fragments may be extruded. Typical expansion of a phalanx Fig B 31-1 along with irregular destruction of bone Hand-foot syndrome in sickle cell anemia. Note the absence of periosteal multiple phalanges and metacarpals is due to infarction. There are reactive bone reaction, which differentiates the appearance changes with sclerosis and periosteal thickening. More destructive lesions may lead to neuroarthropathy and a classic “licked candy stick” appearance and progress to a virtually fingerless hand. Other infections Yaws, syphilis, smallpox, atypical mycobacteria, (Figs B 31-3 and B 31-4) fungal disease. Sarcoidosis Approximately 15% of patients have bone involve- (Fig B 31-5) ment, predominantly in the middle and distal phalanges of the hand. Usually associated with characteristic hilar and paratracheal adenopathy, interstitial pulmonary disease, or both. Leukemia Leukemic changes are generally more diffuse than in osteomyelitis or sickle cell anemia, though the radiographic differentiation may be difficult. Tuberous sclerosis Characteristic abnormalities in the hands and feet (Fig B 31-6) are wavy periosteal new bone formation along the shafts of the metatarsals and metacarpals and cyst- like changes in the phalanges. Pancreatic fat necrosis Infrequent manifestation that probably results from elevated levels of lipase during the acute phase of the disease. In children, the lesions must be distinguished from those caused by infection or sickle cell dactylitis. Examples of cortical and medullary granulomas along phalanx with periosteal calcification forming a dense shell with intense periosteal new bone formation.

Incision and Exposure Make a slightly curved incision in a natural skin crease approximately 1 cm caudal to the cricoid cartilage buy super viagra 160mg amex. Using a scalpel or electrocautery buy super viagra 160mg, carry the incision down through the skin and subcutaneous tissue to the platysma muscle discount super viagra 160 mg line. Place skin hooks or Kelly clamps in the dermis to assist with the cre- ation of sub-platysmal flaps. Using a gauze sponge to pro- vide counter traction, begin medially and carry the dissection out laterally. If the plane of dissection is carried down to the cervical fascia, a number of veins are encountered that pro- duce unnecessary bleeding. There is a thin layer of fat deep to the platysma muscle, and leaving this layer on these veins Fig. Continue the dissection along the deep surface of the platysma muscle in a cephalad direction using both sharp and blunt maneuvers. The superior avascular areolar plane superiorly to the thyroid cartilage gland is generally situated on the posterior surface of the and inferiorly to the suprasternal notch. A self-retaining upper third of the thyroid gland, fairly close to the cricoid retractor may be placed to hold back the skin flaps. Frequently, the parathyroids are loosely surrounded Palpate the prominence of the thyroid cartilage to identify by fat and are golden yellow in color. Make an incision through the cervical fascia in 5–8 mm in maximum diameter, the average gland weighs the midline and extend the incision to expose the full length about 30 mg. Elevate the sternohyoid muscle in the preserve the posterior capsule of the thyroid gland by incis- midline; then elevate the sternothyroid muscle and dissect ing the thyroid along the line sketched in Fig. This permits divide the branches of the inferior thyroid artery at a point adequate digital exploration of the entire thyroid gland. Then dissect each large or the exposure is inadequate, do not hesitate to tran- gland carefully away from the thyroid without impairing its sect the sternohyoid and sternothyroid muscles. Operative Technique Identification and Ligation of the Isthmus Intraoperative Preparation and Middle Thyroid Vein Position the patient supine on the operating room table. Place At this point, some surgeons opt to transect the isthmus of a shoulder roll, if necessary, to assist with extension of the the thyroid. Tuck the arms by the patient’s side and pad all pressure back the strap muscles, identify the isthmus. This maneuver separates the upper pole from the external branch of the superior laryngeal nerve, which is closely applied to the cricothyroid muscle at this level (discussed below). After they have been ligated and divided, the superior pole of the thyroid is completely liberated and can be lifted out of the neck. Now search along the posterior surface of the upper third of the thyroid lobe for the superior parathyroid gland. Dissect the parathyroid gland away isthmus off of the trachea both inferiorly and superiorly from the thyroid into the neck, carefully protecting it. The isthmus may be divided between clamps and vascular control obtained by suture ligation or oversewing of the cut ends. Identification of Inferior Pole Vessels Devices such as a harmonic scalpel or vessel-sealing system may be used to transect the isthmus and may be Next attention turns to identification and ligation of the infe- used throughout the procedure in place of suture ligatures. Staying close to the thyroid tissue, dissect The isthmus may also be divided last, once entire dissec- from medial to lateral and take care not to injure the recur- tion is completed. Locate the inferior thyroid vessels and Once the upper portion of the thyroid isthmus is iden- ligate these vessels using suture ligature or vessel-sealing tified, a fingerlike projection of thyroid tissue may be devices (Fig. In some cases, the thyroid ima artery seen extending from the region of the isthmus in a cepha- may be encountered at this point. If a thyroidectomy is being performed for Graves’ disease, it is important to remove the pyramidal lobe. Otherwise, Identification of the Recurrent Laryngeal postoperatively it may become markedly hypertrophied Nerve and Inferior Parathyroid Gland and cause a significant cosmetic deformity overlying the thyroid cartilage. With both the superior and inferior poles of the thyroid Once this is accomplished, retract the lobe medially and mobilized, the recurrent laryngeal nerve is able to be identi- identify and ligate the middle thyroid vein. Dissection may be carried out lateral to medial or vice improve the mobility of the thyroid and assist in exposure. Retract the strap muscles laterally and the thyroid medi- For most surgeons the best way to locate the recurrent ally. Using blunt and sharp dissection, sweep the lateral laryngeal nerve is to trace the inferior thyroid artery from the tissue away from the lateral most aspect of the thyroid. Often a Ligate the vein using silk ties or other devices, as indicated very slim vessel can be seen along the nerve. This is done by placing an index finger deep along the posterior lamina of the cricoid and stimulating the recurrent laryngeal nerve with a neurostimulator to feel for contraction of the cricoarytenoid muscle through the wall of the hypopharynx. Additional methods to assess functions of the nerve include direct laryn- goscopy or continuous monitoring by electromyography. Intraoperative neural monitoring is gaining widespread acceptance as an adjunct to the gold standard of visual iden- tification of the recurrent laryngeal nerve. It does have some limitations and additional research and standardization of techniques and results is needed. Identify the inferior parathyroid gland, generally located close to the point at which the inferior thyroid artery divides Fig. Divide each of these branches of the inferior thyroid artery between ligatures on a line immediately deep to or superficial to this artery and carefully medial to the parathyroid gland so the blood supply to the dissect the nerve in a cephalad direction until it reaches the parathyroid is not impaired. Dissection may be two or more branches in the area cephalad to the inferior carried out from a lateral to medial fashion, transecting the thyroid artery. Once the nerve has been exposed throughout ligament of Berry to elevate the thyroid from the trachea. These segments may then be placed or injected into a pocket of the sternocleidomastoid or brachioradialis muscle. Generally, a permanent suture to close the pocket and clips are placed to mark the site. Subtotal Thyroid Lobectomy If subtotal resection of the lobe is the operation elected, free the upper pole completely and divide the lobe along the line of resection as outlined in Fig. At this level of the dissection both parathyroid glands and the recurrent nerve, all of which have been previously identified, may be Fig. Divide the remaining gland between hemostats or using a vascular sealing device until the anterior surface of the trachea has been reached.
