In such cases, corresponding bedding will suf- fice to alleviate the pain. Post-polio syndrome Functional deformities The commonest functional deformities are contractures, particularly flexion contractures. These restrict the pa- tient’s ability to walk and increase the energy expended during walking because the knee flexion position requires compensatory postural work by the knee extensors to maintain an upright posture. These contractures usually have to be considered in connection with other problems of the lower extremity (knee flexion) so that a correspond- ing strategy that deals with all the problems together can be prepared. AP x-ray of the pelvis in spinal muscular atrophy with left hip dislocation Structural deformities As a result of the reduced usage, the skeleton of the af- fected extremities becomes thinner and smaller. Since it Structural changes is incredibly robust, however, fractures do not occur with Hip dislocations occur as a result of the failure of the greater frequency. But otic spinal deformity is another possible causative factor, provided no functional restriction results, such structural hence also the benefit of early correction of the spinal deformities are of no concern.

Critically ill burned pa- tients present with a high risk for respiratory infections. Besides the already mentioned inhalation injury, patients have consecutive septic showers, during subsequent trips for surgery, dressing changes, or septic episodes. Moreover, burn patients often have problems with deglutition that pose a risk of aspiration pneumonia. Sudden changes in the patient’s hospital course and in his or her respiratory status should alert the physician to seek respiratory complications. Aggressive respiratory toilet and empirical systemic antibiotics should be started and ventilatory support reserved for cases of frank respiratory failure. Nosocomial pneumonia is generally a gram-negative infection and systemic antimicrobial therapy with multiple agents is generally required until the infection resolves clinically. Burn wound bacterial surveillance is of added value to direct empirical antibiotics, since organisms isolated in respiratory infections reflect burn wound flora in many instances. On the other hand, patients with ventilatory support present with a microbial spectrum that resembles the typical ventilatory-depen- dent patient pneumonia. Tracheobronchitis presents with a heavy gram-positive colonization, putting patients at risk for gram-positive pneumonia. Urinary Tract Infections Urinary tract infections can be classified into upper and lower urinary tract infec- tion. True pyelonephritis is very rare in burn patients; however, lower urinary tract infection can occur as a result of a chronic indwelling Foley catheter. Urinary tract infections are diagnosed based on positive culture greater than 1 105 organisms cultured from a urine specimen. Urinalysis may reveal white cells and cellular debris associated with active infection. Positive urinary cultures are common during the course of sepsis, and they are also treated in the general context of that particular septic episode. It must be noted, however, that the association of clinical signs of sepsis with burn wound cultures or blood cultures with positive urinary cultures make the final diagnosis of sepsis. Other information about organ involvement, such as positive findings on funduscopic examination, is necessary to make this diagnosis. In general, isolated urinary tract infections are treated with appropriate systemic therapy with good urinary extraction. If there is suspi- cion of an ascending infection or sepsis, more aggressive treatment with prolonged systemic antimicrobials is warranted. Catheter Related Infections Central and arterial line placement, catheter care, and protocol have been dis- cussed in Chapter 1. Catheter-related sepsis is associated with prolonged indwell- ing central and arterial catheters. Catheter sepsis may be primary, in which the General Treatment 53 catheter is the original focus of infection; or secondary, in which the catheter tip is seeded and serves as a nidus for continued shedding of micro-organisms into the bloodstream. Lines can be associated with the development of both gram- negative and gram-positive sepsis. Central and arterial lines represent an avascular foreign body and, as such, are prone to microbial seeding.

The result is ide- ally stabilized with an external fixator, since the proximal fragment is usually too short for stable anchorage with a plate. Normally the deformity occurs on both sides and is in- herited as an autosomal-dominant condition. Clinical examination reveals a fixed flexion contracture of the affected joint: A passive and active extension deficit is present. This can be observed when the metacarpopha- langeal joint is in both the extended and flexed positions. On the x-ray there is recurvation of the distal end of the proximal phalanx, while the joint head is deformed and angulated towards the palm.
