Attention is directed to the medial aspect effective 160mg malegra fxt plus, where the arch should be palpated 160mg malegra fxt plus fast delivery, and if the tuberosity of the navicular is very prominent generic 160mg malegra fxt plus visa, the insertion of the tibialis posterior should be excised from the navicular without excising any cartilage cheap 160mg malegra fxt plus mastercard. Then cheap malegra fxt plus 160mg, the navicular tuberosity is excised parallel to the edge of the head of the talus and the navicular cuneiform joint. The insertion of the tibialis posterior is reattached with heavy suture, which is sutured through the bone of the navicular and cuneiform. The skin is closed with a rapid absorbable suture, usually using plain gut suture both medially and laterally. Postoperative Care Postoperative management includes the use of a short-leg, full weightbear- ing cast for 6 to 8 weeks. Weight bearing is allowed as soon as pain is toler- ated. After the cast is removed, no orthotics are used until it is determined whether the foot is in a stable position, or the child needs orthotics for an- kle control or a tendency for foot collapse. Lateral Column Lengthening Through the Calcaneus Indication Calcaneal lengthening is indicated for children who are high-functioning ambulators and whose hindfoot valgus, external rotation, and posterior facet subluxation deformity are supple and of mild to moderate severity. Options for correction of the lateral column shortening and abduction include cal- caneal lengthening between anterior and middle facets, opening wedge of the anterior lateral corner of the calcaneus, calcaneocuboid fusion with length- ening, or a medial displacement varus calcaneal tuberosity osteotomy (Fig- ure S5. Excision of the fifth metatarsal tuberosity may be added if it is noted to be prominent. The skin and subcutaneous exposure with cleanout of the sinus tarsi is the same as for the subtalar fusion (Figure S5. The interval just anterior to the middle facet is identified in the sinus tarsi. Subperiosteal dissection is performed on the lateral calcaneus from the capsular insertion of the calcaneocuboid joint anterior and then extended posterior to the middle of the calcaneal tuberosity. Sub- periosteal dissection is undertaken around the inferior border of the lateral calcaneus. A retractor is placed around the inferior border of the lateral calcaneus. An oscillating saw is used and the calcaneus is transected in the trans- verse plane at the level just anterior to the middle facet (Figure S5. If the medial side of the calcaneus is not completely tran- sected with the saw, it should be completed with an osteotomy (Fig- ure S5. The osteotomy now should be free and easy to be distracted, usually using a lamina spreader at the superior lateral corner of the osteotomy. The osteotomy is spread until the foot appears to be corrected. If the peroneus brevis is contracted limiting the amount of opening of the osteotomy, a separate incision is made 6 to 8 cm proximal to the tip of the lateral malleolus, and the peroneus tendon is exposed posterior to the fibula. If good muscle belly is present, a myofascial lengthening is made; however, if only tendon is encountered, a Z- lengthening of the peroneus brevis is performed. By spreading the osteotomy with a Cobb elevator or lamina spreader, the forefoot should swing into adduction and supination should cor- rect. The osteo- tomy is distracted until the forefoot adduction and supination have been corrected, usually requiring approximately 10 mm of lateral opening. Using the amount of distraction as a guide, bank bone or the patient’s iliac crest bone is harvested and shaped into a trapezoid with the wide area pointing lateral and superior in the osteotomy. Usually, the width of this graft is approximately 1 cm on the wide side and 5 mm on the narrow end, but the specific size should be determined by the amount of distraction needed (Figure S5. The osteotomy is fixed with a longitudinal K-wire or with a two-hole semitubular plate (Figure S5. The foot again is assessed carefully to determine if there is any first ray elevation of the medial column, especially to determine if first ray elevation occurs with dorsiflexor pressure on the plantar surface. Also, if dorsiflexor pressure causes forefoot abduction and dorsi- flexion through the lateral column at the calcaneocuboid joint, this deformity also needs to be corrected. Additional medial and lateral column correction is performed utilizing procedures discussed in cal- caneocuboid joint lengthening and forefoot supination and medial ray elevation procedures.
All children except those in excellent health and with relatively good motor function are started on 9 order malegra fxt plus 160 mg amex.

When gastro- intestinal feeding has been reestablished cheap 160 mg malegra fxt plus with mastercard, the central venous hyperalimenta- tion is discontinued. As soon as children are extubated, they are gotten up in a chair, usually starting with a reclining wheelchair. These children should not be placed in their own wheelchairs until a physical therapist has evalu- ated and adjusted the chairs to make certain there are no pressure points. The dramatic change in these children’s body shape usually makes the pre- operative chair fit very poorly. By forcing children into these chairs, they run the risk of developing pressure points and skin breakdown. The children are discharged when they are eating approximately 1. The children may return to school as soon as they can sit long enough, which usually is after 2 to 4 weeks at home. Families and caretakers are told that there are no restrictions on discharge and that the children may bathe, go swimming, and start all pre- operative activities in which they are comfortable. For children who have an uneventful surgery and recovery, we try to have them home by postoperative day 7 and back to school by 3 weeks after surgery. When we first see them in the outpatient clinic 5 weeks after surgery, they are expected to be back to most activities but are still continuing to have some discomfort and de- creased endurance. By 6 months of postoperative follow-up, we expect the children to have recovered fully and be back to all activities in which they were engaged in preoperatively. Anterior Surgery Anterior release is done to improve the flexibility of the spinal deformity, not for the goal of providing a fusion. The indication for anterior release is severe stiffness in any child and a large curve of more than 90° and moder- ate stiffness in an older child. In the past, we did the anterior surgery staged, with 1 week between the anterior and posterior procedures; however, in the past 8 years we performed the anterior surgery on the same day as the pos- terior surgery. In healthy children, having both procedures on the same day may enable them to recover more quickly and go home faster. However, for children with severe curves and multiple medical problems, the posterior surgery should be delayed for 1 to 2 weeks. We have found increased com- plication rates in same-day surgery when compared to staged anterior spinal release. Because anterior surgery is done to gain flexibility, no anterior in- strumentation should be inserted and the disk spaces should not be packed 452 Cerebral Palsy Management solid with bone graft. Only loose pieces of bone graft from the resected ribs should be inserted and most of that kept at the edge of the disk space. Crankshaft Crankshaft has been identified as a common cause of progression of sco- liosis after instrumentation and fusion in immature children. Crankshaft was especially a problem in the original Luque system. We have found no progression in 29 immature children fused with the Unit rod before clo- sure of their triradiate pelvic cartilages and followed to the completion of growth. However, all these reports have mixed populations of CP, myelomeningocele, and muscle patients that make any re- alistic assessment of their specific results in children with CP difficult. Complexity of the instrumentation, cost, and length of operative time are all significantly greater than the Unit rod. Outcome The outcome of the technical improvement in the children’s trunk alignment is excellent with the Unit rod. Correction of the scoliosis of 70% to 80% of the preoperative curve and correction of the pelvic obliquity of 80% to 90% of the preoperative curve with normalization of kyphosis and lordosis is expected. There is, however, almost no reported litera- ture on isolated kyphosis in CP.
