The commonest accessory bone is the accessory has not been mentioned by subsequent authors. The os subfibulare corresponds with the separate apophyseal center that is often present at this site 393 3 3. As the bone often protrudes significantly on the medial side it can rub against hard shoes, leading to inflammation and swelling. The result- ing pain will then depend on the respective footwear worn by the patient. Occasionally these symptoms also occur at this site even when no accessory bone is pres- ent. Instead, the navicular bone is very prominent on the medial side, in which case it is described as a »cornuate navicular bone«. A projecting bone in the area of the navicular can be classified as one of 3 types: In type I, an ossification center exists in the tendon of the posterior tibial muscle. In type II, the os tibiale externum forms a synchondrosis with the navicular while, in type III, no separate ossifi- ⊡ Fig. The os subfibulare is not an accessory ossification center, but cation center is present, but rather the aforementioned a traumatic rupture of the cartilaginous attachment of the anterior cornuate navicular bone. Type II may develop over time talofibular ligament that subsequently ossifies into a type III situation. The os subfibulare can also oc- casionally cause pain and is located at the distal end of the fibula, slightly in front of the lateral malleolus. As already mentioned, this is usually a traumatically avulsed ossification center. It can cause symptoms particularly in connection with loosened lateral ligaments and chronic instability. In very rare cases, the os trigonum can cause symptoms, generally after trauma to what is actually a very common accessory ossification center. Besides accessory ossification centers, congenital cleft formations can also occur, although these are extremely rare. Multiple forms, part of a complex syndrome: that was giving rise to symptoms. If this is removed, the surgeon must be careful – Proximal focal femoral deficiency ( Chapter 3.

In such cases, relief is provided only by purely descriptive and based on observations made dur- surgical removal of the os tibiale externum or chiseling off ing operations.

All electrical burns are full-thickness and should be assumed to be fourth- degree generic malegra dxt 130mg line. Flash burns are rarely full-thickness discount 130mg malegra dxt amex, except in areas of very thin skin malegra dxt 130mg sale. Burns from hot soups and sauces are deeper than those from hot water alone 130 mg malegra dxt fast delivery. Principles of Burn Surgery 137 Burns resulting from direct contact with a tar pot are usually very deep dermal or full-thickness burns, while those from tar that has been trans- ferred into a bucket or spread on a surface are usually shallow. Small burns that will eventually heal present little threat to life if allowed to heal over several weeks. Inadequate excision with skin grafting on a poor bed leads to skin graft loss, adds the size of the donor site to the total area of open wounds, and may necessitate another operation. Non-life-threatening burns in patients with associated medical problems or injuries should not be excised until the associated problems are under control and the operation can be done with low morbidity and essentially no mortality. Patients with burns of the hands and feet will be able to return to work sooner if their burns are excised and skin grafted shortly after hospital admission. Large, superficial burns with scattered small deeper components are best treated nonoperatively until the shallow areas have healed. Early excision decreases the need for wound cleansing and daily debride- ment. If pain management becomes a significant problem, this in itself is an indication for excision. A patient with a small burn who can continue to work despite the burn and who can manage the wound at home will have the least expensive care and, in the long run, will miss much less work than if the burn is excised. Small deep burns can be treated initially on an outpatient basis and then excised and skin grafted electively on a day surgery schedule. PATIENT PREPARATION FOR SURGERY Complete resuscitation Before a patient is taken to the operating room for excision of a burn wound, we recommend that he or she be completely resuscitated. That is, he or she should have adequate urine output receiving only maintenance intravenous fluid adminis- tration or in combination with enteral nutrition. In patients with extensive full-thickness burns, who still require large volume fluid resuscitation beyond the first 48 h excision of some of their burn before resuscitation is com- plete may be necessary. Nutrition It is well known that early and aggressive enteral nutrition in the thermally injured patient improves mortality, decreases complications, optimizes wound healing, 138 Heimbach and Faucher and diminishes the catastrophic effects of protein catabolism. Nutritional support should be instituted immediately upon admission and continued throughout the acute phase of burn care. It has been shown in a randomized study that nearly continuous nutrition throughout the perioperative period maintained nitrogen bal- ance and improved outcome [13,14]. Jenkins also showed that continuous feeding throughout the perioperative period does not risk aspiration in intubated patients. Intubated patients taken to the operating room do not need to have their feedings discontinued before or during surgery. It is the practice at our institution to continue tube feedings for intubated patients throughout the periop- erative period. We stop tube feedings and allow nothing orally in nonintubated patients for 4 hours prior to induction. Preoperative laboratory evaluation Our daily laboratory evaluation of patients consists of a full electrolyte panel and complete blood count. Prothrombin and partial thromboplastin times are checked only if there is concern based on the patient history that they could be abnormal. We ensure that all electrolytes are in within the normal range prior to operative intervention. Over the past 20 years, we have become better at limiting blood loss during surgery.

Congenital hammer toes Congenital hammer toes are usually recognizable in the ﬁrst year of life malegra dxt 130 mg otc, and are routinely inherited discount 130mg malegra dxt mastercard. The “hammering” generally involves the second generic malegra dxt 130 mg free shipping, third, and fourth Figure 3. The distal interphalangeal joint is most valgus foot and congenital vertical talus. The clinical appearance is characteristic and resembles a “hammer”, by virtue of the distal phalanx being plantar ﬂexed and rigid, relative to the middle phalanx, which lies in extension (Figure 3. Secondary to the rigidity, a painful corn commonly develops on the dorsal surface of the proximal or distal interphalangeal joint, precipitating medical attention. Symptomatic presentation usually occurs in the latter portion of the ﬁrst decade to adolescence. A protective sponge “donut” may be used over the painful corn to relieve discomfort temporarily, but most patients will eventually require more deﬁnitive procedures designed to Figure 3. Lateral radiograph illustrating congenital vertical talus with straighten the affected joint and fuse it in a equinus of the calcaneus and dorsiﬂexion of mid- and forefoot. Surgical treatment should be reserved for those who have failed conservative care. Congenital overlapping ﬁfth toe This condition is nearly always recognizable at birth, but may become more fully manifest symptomatically in the ﬁrst two to three years of life. The ﬁfth toe is dorsiﬂexed, adducted, and slightly externally rotated, and literally comes to lie on the dorsal surface of the fourth toe (Figure 3. Soft tissue contracture of the dorsal and medial structures of the ﬁfth metatarsal phalangeal joint has been indicted Figure 3. Clinically, the toe Common orthopedic conditions from birth to walking 40 not only lies dorsally and in an adducted position over the top of the fourth, but it cannot passively be reduced into its normal relationship. Those children who are symptomatic present with discomfort overlying the ﬁfth toe with corns and painful calluses secondary to shoe wear. In general, surgical treatment should be reserved for only those cases in which substantial discomfort is present, and soft protective pads have failed. Most of the cases presenting with symptoms will eventually require surgical correction. Soft tissue releases, tendon rerouting, and metatarsophalangeal joint fusion provide the basis for reconstruction. Supernumerary digits Polydactyly, or supernumerary digits, is one of the most commonly seen congenital conditions in children. Most commonly the extra ﬁnger or toe is a mirror image of the digit lying directly adjacent to the extra digit (Figure 3. The apparent extra digit is in competition with the adjacent digit for the tendons activating that ﬁnger or toe. It is very important to determine tendon function in the presumed supernumerary digit so as not to become embarrassingly involved in the removal of a very functional part. Nearly always the indication for surgical removal is cosmetic, or as a consequence of difﬁculties in obtaining conventional shoe wear. Trigger thumb Stenosing tenosynovitis of the thumb, more commonly known as “trigger thumb,” is one of the more common congenital abnormalities of the hand. It is rarely recognized in the ﬁrst six months of life since children generally maintain Figure 3. As the child begins to reach, grasp, and grip objects, it becomes apparent that the thumb does not fully extend at the interphalangeal joint. The deformity may manifest itself in periodic episodes of ﬂexion deformity of the interphalangeal joint with occasional episodes of popping, clicking or full straightening of the ﬁnger. More commonly it is recognized when the thumb is persistently held in a position of interphalangeal joint ﬂexion (Figure 3. The parents relate that the thumb does not fully straighten, and that the child has some difﬁculty in grasping. On examination, a palpable nodule is readily discerned at the metacarpophalangeal joint level, at or near the proximal metacarpophalangeal thumb crease. There is (a) (b) inability to extend the interphalangeal joint of Figure 3.
