Cardiac involvement is uncommon and probably accounts for the continuing ambulatory status generic premarin 0.625mg with mastercard. Far less commonly encountered is limb-girdle dystrophy order 0.625 mg premarin with visa, an autosomal recessive dystrophy order 0.625 mg premarin amex. The diagnosis is generally not established until the second or third decade purchase 0.625mg premarin with amex. It is a slowly progressive disease primarily involving the pelvic and shoulder girdles, with rare pseudohypertrophy in the calf. It is generally differentiated from pseudohypertrophic muscular dystrophy by the late onset, the more benign pattern, and only slight elevation of the creatine kinase level. Another uncommon form of muscular dystrophy seen in the later part of the ﬁrst and second decade is facio-scapulo-humeral From toddler to adolescence 76 dystrophy, an autosomal dominant disease. Characteristically the muscles of the shoulder girdle and face are affected, and it is a slowly progressive disorder. Clinical ﬁndings include muscle weakness, inability to close the eyes tightly, “pouting” of the lips, and absent facial wrinkles. Muscle biopsy demonstrates a dystrophic type pattern with very large muscle ﬁbers and an inﬂammatory response. Interestingly the creatine kinase levels are usually within normal limits. An awareness of developmental delays and maturation should alert one to formally examine for any areas of muscle weakness. Once the diagnosis has been established, the needs of the patient are directed to the cardio-respiratory status combined with appropriate orthopedic management and physical therapy. Orthopaedic procedures of the spine, hip, knees and ankle level may occasionally delay the transit into a wheelchair and may also improve the quality of life, particularly in regard to the management of scoliosis by early spinal stabilization of progressive scoliosis. Recent use of corticosteroids has shown promise but long-term evaluation remains necessary. Ko¨ hler’s disease Kohler’s disease is a nutritional disorder of the¨ tarsal navicular that results in an avascular necrosis. It nearly always makes its appearance between the age of three and seven years, and is somewhat more common in males. The child presents with an antalgic limp with pain localized on compression in the area of the 77 Discoid meniscus (a) tarsal navicular. The diagnosis is established by a combination of symptomatology coupled with a radiographically fragmented, irregularly dense appearance to the tarsal navicular (Figures 4. The tarsal navicular does not begin to ossify until roughly age three and often may be irregular and fragmented as a normal variation in its ensuing ossiﬁcation pattern. The diagnosis of Kohler’s disease should be¨ established only when there is a combination of radiographic ﬁndings and localized symptomatology. Treatment consists of short-term casting and perhaps brief periods of diminished weight bearing. The prognosis is uniformly excellent with symptomatology disappearing generally within several months after its appearance. Discoid meniscus Discoid meniscus is usually seen between one and eight years of age although occasional cases have been seen under one year of age. A child with a discoid meniscus commonly will present with a complaint of a “clunk” or a “clicking” sensation in the knee with or without (b) discomfort. Occasionally “falling” or reluctance to move the knee through a range of motion is observed. On examination, a characteristic “clunk” or “snap” is perceived on moving the knee through a range of ﬂexion and extension. The clinical ﬁndings are most commonly directed to the lateral compartment of the knee and the lateral joint line. The basic pathoanatomy is the presence of a discoid-shaped meniscus rather than the Figure 4.

The need to wait at least 3 weeks until the second surgery and the separation of the flap from its donor tissue make it very difficult to care for the burned limbs and prevent proper mobilization therapy and splinting order premarin 0.625mg free shipping. For these reasons these flaps are increasingly being replaced by regional fasciosubcutaneous flaps order 0.625mg premarin visa, or free flaps order 0.625mg premarin free shipping, for coverage of complex injuries of the limbs premarin 0.625mg free shipping. Some very useful examples are fascial axial flaps, fasciosubcutaneous flaps, or reverse-flow fasciocutaneous flaps based on the radial, cubital, or posterior interosseous arteries for hand coverage. These flaps also allow the transfer of segments of tendon, muscle, or bone, which adds great versatility to reconstruction methods. The reverse-flow radial flap, as described by Lu in 1982, is a modification of the free antebrachial fasciocutaneous flap described by Yang in 1978. It is a flap based on the septal perforating branches of the vascular system of the radial artery, perfused in a retrograde direction from the palmar arch, whose permeability is tested preoperatively using the Allen test. Venous drainage occurs in a retrograde fashion through the concomitant radial veins, which occasionally creates initial signs of venous congestion that later disappear. It is very important to exercise maximum caution while dissecting the fascial wall to avoid damaging the superficial branches of the radial nerve in the distal third of the forearm. Figure 4 shows an example of the placement of this flap in the treatment of a severe hand burn. The reverse-flow cubital flap, described by Jin in 1985, is very similar to the one just described and is used less frequently since it is considered the main vascular supply to the hand. The feasible cutaneous territory of this flap is less than the flap based on the pedicle of the radial artery. The reverse-flow fasciocutaneous flap based on the posterior interosseous artery was described by Zancolli and Angriniani in 1985. Blood flow arrives in a retrograde fashion to the septocutaneous perforating branches from the posterior interosseous artery via the communicating branch, with the anterior interosseous artery located distally in the forearm. This is indicated specifically for treatment of deep burns of the thumb, the first commissure, and the dorsum of the hand (Fig. In 1988, Ching described the anatomical basis for the antebrachial fascio- subcutaneous flap distally based on septocutaneous perforating branches of the radial and cubital arteries the level of the distal third of the forearm, with the preservation of the integrity of these vascular axes. These flaps are useful for coverage of complex distal injuries of the forearm and hand. The Hand 271 FIGURE 4 Reverse-flow radial flap for treatment of a hand burn. FIGURE 5 Reverse-flow fasciocutaneous flap for coverage of a burned hand. When tissue destruction prevents the use of local or distant flaps and when, necessary for reconstruction, free flaps are indicated for treatment of burned hands. Using microsurgical techniques, it is possible to transfer in a single surgical procedure the tissue necessary for optimal coverage of the exposed blood vessels, nerves, tendons, joints, or bones. This helps reduce the risk of deep infection and necrosis of the exposed soft tissue structures and facilitates early movement of the burned extremity. This is especially relevant for the treatment of patients who have suffered high-voltage electrical burns of the upper limbs. Coverage of the burned hand requires the use of tissues that are not very thick. The existence of this with a fascial component in the flap that allows sliding of the exposed deep structures is another advantage of free flaps. The free radial fasciocutaneous flap, described by Yang in 1981, provides excellent coverage with a thin, pliable tissue with a fascial component on its deep surface. Its vascular pedicle is constant, of large caliber, and has supplementary drainage through the superfi- cial veins of the forearm. This type of flap is contraindicated when the Allen test shows insufficient vascular supply from the cubital system and the posterior interosseous of the hand [26,47] or when the skin of the donor region of the forearm has been burned. We do not reconstruct the radial artery after extracting the flap, and we have not observed any case of poor perfusion of the hand of the donor extremity.
