Immediate hip spica casting for femur fractures in pediatric patients. A review of 175 patients.

Immediate closed reduction and application of a well-molded hip spica cast is a safe and effective treatment option for closed, isolated femur fractures in children who weigh between 10 and 100 pounds. Between 1988 and 1996, 190 immediate hip spica casts were placed on children with isolated femoral shaft fractures who weight between 10 and 100 pounds. Fifteen patients were lost to followup leaving 175 children who were evaluated and followed up for at least 2 years after the hip spica cast was removed (range 2-10 years). The femur fractures were reduced closed and placed in a 1 1/2 hip spica cast in the emergency room with the patient under conscious sedation or in the operating room with the patient under general anesthesia. All of the children returned home within 24 hours of the procedure. All 175 femur fractures united within 8 weeks. The only complication was a refracture in a 25 pound child who fell 1 week after the cast was removed. No significant residual angular deformities were present in any of the children at last followup. None of the children required external shoe lifts, epiphysiodesis, antibiotics, irrigation and debridements, or limb lengthening procedures for leg length inequalities. The authors think that immediate closed reduction and placement of a well-molded hip spica cast is a safe and reliable treatment option for isolated, closed femur fractures in children from birth to 10 years of age who weigh less than 80 pounds.

Factors affecting hip fracture mortality.

This retrospective analysis of 300 patients with proximal femoral fractures was undertaken to determine what factors were significant and nonsignificant in determining patient mortality. Mortality rates were based on survival of the patient 1 year after surgery. Of 283 patients followed until death or for at least 1 year postoperatively, the mortality rate was 14.8% (42/283). The expected mortality rate for the normal population over 50 years of age is 3%. Factors considered significant in influencing patient mortality were age, number of pre-existing medical conditions, postoperative level of ambulation, and delay of surgery for more than 24 h in relatively healthy patients. The authors feel that on the basis of this study, healthy patients should undergo surgery within 24 h of admission and less healthy patients can be stabilized medically before undergoing surgery without adding increased risk from the delay.

Experience with an intraoperative autogenous blood recovery system in scoliosis and spinal surgery.

A clinical trial of an intraoperative autogenous blood recovery system shows that while the method is safe, the cost in spinal surgery is quite high. The unit was used in 20 procedures in 18 patients thought to have increased risk of intraoperative bleeding (mature idiopathic, congenital, myelomeningocele, Marfan's, and irradiation scolioses and late spinal fractures). Collection in four procedures was either insufficient for use of contaminated. In the remaining 16 cases, 20% of the blood loss was recovered. A total of ten units of blood was recovered, at a cost of $283/unit; this is four times the current cost for a unit of blood in the local blood bank. The method would be more beneficial if a huge blood loss were anticipated, as most of its cost is incurred in the setup, and the higher the blood loss at surgery, the higher the percentage of the yield might be. The method may be useful with rate blood types and for patients with religious objections to transfusions.
