Patellar tendon rupture with underlying systemic disease.

Two patients with patellar tendon rupture and underlying systemic disease are described. One had systemic lupus erythematosus and the other had chronic renal failure and secondary hyperparathyroidism. There have been 13 other cases of patellar tendon rupture in patients with systemic disease reported in the literature and they are reviewed. Patellar tendon rupture has occurred spontaneously in more than one-half of the cases and has been associated with rupture of the contralateral extensor tendon mechanism in 87%. Although patellar tendon rupture almost always occurs at the tendinous insertion, on a rare occasion (as in one case described in this report), the tear may involve the main substance of the tendon, which is the part of the tendon with the greatest tensile strength. The relation between systemic disease and patellar tendon rupture is discussed and the clinical and radiographic findings are described.

The Guillain-Barre syndrome in children. Orthopedic management and patterns of recovery.

Eleven cases of Guillain-Barre Syndrome in children between 1955 and 1973 demonstrate clinical course and residual permanent motor deficits. The rate of recovery from muscle paralysis and the long-term permanent muscle loss, and the resultant paralytic deficits may require treatment: tendon transfers, opponensplasties, spinal fusions, and Lambrinudi operations. The late permanent motor paralysis and residual joint deformities secondary to GBS in children has a higher incidence and severity than in adults, and an intensive rehabilitation program in imperative. Frequent, extended follow-up, and muscle testing records are absolutely essential in children.

Low-velocity gunshot wounds in police officers.

One hundred forty-five Philadelphia police officers were injured as a result of gunfire during the period from January 1971 to February 1983. Arrests and arrest attempts were the most common causes of these injuries; on- and off-duty accidents were the second most common causes. Twenty fatalities occurred among the 145 officers. Specific medical and surgical management of gunshot wounds depended largely on the location of the wound and the extent of the damage. Analyses of the location of the wounds in this study revealed that many could have been alleviated through the use of body armor, such as bullet-proof vests and lightweight helmets. Of the treatment records of 100 patients completed for evaluation, average hospitalization time was ten days, time without duty averaged 143 days, and limited duty averaged 70 days. Twenty-two persons received permanent and partial disabilities related either partially or wholly to their wounds. Fourteen individuals expressed anxiety about returning to work as police officers, and two received disability retirements for emotional instability. An officer who is aware of the probability of injury while performing a specific task can decide whether to wear an armored helmet or bullet-proof vest at the appropriate time. In the treatment of low-velocity gunfire injury, the physician could use the guidelines reviewed for specific treatment of the injury and thus anticipate the length of time or probability of the individual returning to work. Early recognition of these factors could help to avoid psychologic trauma.

The temperature problem at the bone-acrylic cement interface of the total hip replacement.

Loosening of total joint replacements may be caused in part by thermal necrosis of bone in contact with the high temperature of the polymerizing PMMA acrylic cement. This study reports a method to reduce the temperature of the bone-cement interface below the temperature at which bone results in definite necrosis. By precooling the acetubular component to --84 degrees before insertion into the cement, the temperature during polymerization at a simulated bone-cement interface can be reduced from 70 degrees to 49 degrees with an increase of only approximately 51/2 minutes in the cement setting time.
