Comparative StudyThe effect of age on the change in deformity after radical resection and anterior arthrodesis for tuberculosis of the spine.
We compared the long-term changes in spinal deformity after a radical operation for tuberculosis of the spine in thirty-three children who were ten years old or younger at the time of the operation with those of seventy-one adult patients who were at least eighteen years old at the time of the operation. The spinal deformity was measured with use of the angles of kyphosis and deformity as assessed on lateral spinal radiographs made preoperatively and postoperatively at six months, one year, and five years and at the most recent follow-up evaluation (at a mean of fifteen years). We detected no significant difference in the mean angles of kyphosis and deformity between the children and the adults postoperatively at any follow-up evaluation; thus, we found that growth of the posterior portion of the spine does not contribute to the progression of deformity after a radical anterior procedure. ⋯ However, there were no such differences in the correction of the deformity between the adults and the children who had tuberculosis of the thoracolumbar or the lumbar spine. Our findings clearly show that a short anterior spinal arthrodesis done at an early age was not associated with progression of deformity during growth and development in our patients. The longitudinal pattern of changes in deformity was similar in the children and the adults, and there was no evidence of disproportionate posterior spinal growth contributing to the progression of deformity after anterior spinal arthrodesis.(ABSTRACT TRUNCATED AT 250 WORDS)

Upper-airway obstruction and perioperative management of the airway in patients managed with posterior operations on the cervical spine for rheumatoid arthritis.
We reviewed the records of 128 patients who had a total of 128 consecutive posterior operations on the cervical spine for problems related to rheumatoid arthritis. Our purpose was to examine perioperative complications related to the airway. The patients were divided into two groups for analysis on the basis of the technique of intubation that had been used. ⋯ The only significant difference between the groups was the time to extubation, which averaged 17.9 hours in the fiberoptic group and 10.6 hours in the non-fiberoptic group (p = 0.02). Logistic regression analysis showed that non-fiberoptic intubation was the significant risk factor, even when allowance was made for the difference in the lengths of time to extubation. We concluded that this life-threatening complication can be minimized with fiberoptic management of the airway.

The use of a bone allograft for reconstruction after resection of giant-cell tumor close to the knee.
The results of bone-allograft reconstruction after the resection of giant-cell tumor close to the knee were reviewed in fifty-two patients (fifty-five allografts), who had been followed for a mean of seven years (range, two to twenty-four years). One giant-cell tumor was graded as stage 1; twenty, as stage 2; and thirty-one, as stage 3. Three reconstructions were repeated transplants that were done after the failure of a previous transplant. ⋯ Major complications included infection (after three reconstructions), resorption of the graft (six), collapse of the articular surface (two), fracture (two), and recurrence (one). According to the criteria described by Mankin et al. for functional analysis, forty-two (76 per cent) of the extremities had a result that was considered to be excellent or good. Radiographic evaluation according to the system of the Musculoskeletal Tumor Society showed a mean score of 72 per cent for osteoarticular reconstructions, and of 86 per cent for intercalary reconstructions.

Comparative StudyOpen tibial fractures with severe soft-tissue loss. Limb salvage compared with below-the-knee amputation.
The long-term outcomes and the quality of life were studied in patients who had had an open fracture of the tibial shaft with severe soft-tissue loss. Limb salvage with a free flap was attempted in twenty-seven patients (sixteen of whom had a successful procedure and were examined personally by us), while eighteen patients were managed concurrently with an early below-the-knee amputation. Soft-tissue coverage was successful in all but one patient in whom limb salvage had been attempted. ⋯ They also had more problems with the performance of occupational and recreational activities (p < 0.05). This study confirmed the reliability of modern microvascular free tissue techniques for the coverage of large soft-tissue defects associated with tibial fractures. It also showed that complications and difficulties in the restoration of osseous union are common and may be directly related to the less satisfactory functional, occupational, recreational, and quality-of-life outcomes that are seen in many patients who have had limb salvage.(ABSTRACT TRUNCATED AT 400 WORDS)
