摘要:

Rounding off the femoral neck metaphysis helps improve hip function in slipped capital femoral epiphysis (SCFE). Remodeling by physeal growth, not previously reported, may also contribute. By studing the changes in physeal-shaft angle after internal fixation (IF), we found evidence of physeal remodeling in one of 21 mild, five of 23 moderate, and in all of 11 severe slips. Although the amount of remodeling averaged 11.7°, it occurred in 100% of severe slips (p < 0.001). This supports the use of initial pin fixation and a wait of at least 2 years before realignment femoral neck osteotomies are considered.

摘要:

Various conventional roentgenographic methods have been proposed to determine the severity of chronic slipped capital femoral epiphysis (SCFE) on the sagittal plane, with some maintaining that computed tomography (CT) is more accurate and reproduces better than roentgenography. We used a modified Dunlap's technique and angular measurement to determine slip severity. Three orthopaedists obtained data from roentgenograms and CT of 20 hips with chronic SCFE. Statistical analysis showed concordance between our method and the measurements and reproducibility produced with CT. The results suggest that our method is as effective as and less expensive than CT.

摘要:

We used three-dimensional computed tomography (CT) to define the bony configuration of the acetabulum and the proximal femur and their relationship to complicated and/or neglected congenital hip dislocations and Legg-Calvé-Perthes disease. Three-dimensional CT was useful for preoperative planning and postoperative evaluation of hips with complex deformities, which were often difficult to assess by means of plain radiographs or conventional two-dimensional CT. The coverage of the femoral head under the acetabular roof and the severity of the hip dysplasia could be assessed easily with three dimensional CT, and acetabular and femoral torsion could be measured.

摘要:

A femoral varus osteotomy can be used to contain the femoral head in Legg-Calve-Perthes (LCP) disease if certain pitfalls can be avoided. We reviewed 74 patients who underwent 79 femoral varus osteotomies. The study addressed the pitfalls that should be avoided with this technique. It was concluded that the amount of varus angulation should barely position the femoral head beneath the lateral rim of the acetabulum, avoiding varus < 105°, and that consideration should be given to performing a greater trochanteric epiphysiodesis at the time of initial femoral osteotomy. The short-term results reflect a positive attitude toward femoral varus osteotomy in treatment of LCP if these pitfalls can be avoided.

摘要:

Three hundred eighty-three pairs of gloves were tested for punctures after 100 consecutive pediatric orthopaedic operations to assess the rate, site, procedure, and maneuver during which glove puncture accidents took place. Evidence of perforation was found in 14% of the gloves used. Surgeons appear to be significantly more at risk for glove perforation than do other members of the operating team.

摘要:

Neonatal fractures in all neonatal patients entering a spina bifida clinic over a 4-year period were reviewed retrospectively. Of six patients with fractures, all had thoracic or upper lumbar neurologic levels and all had significant contractures. The risk of fracture for patients with these two characteristics was 17%. Awareness of the risk of neonatal fracture and care in the handling of these children is stressed.

摘要:

Preoperative aortograms were reviewed in six children with thoracic myelomeningocele and lumbar kyphosis at an average age of 25 months. In all children, the abdominal aorta bridged the lumbar kyphosis. In four children, the upper renal poles were close to the spine and were at potential risk during kyphectomy. All children had aortic shortening with an increased variability in origin of the major abdominal aortic branches. Abnormal lumbar arteries were noted in four children.

摘要:

Forty-two patients with congenital spinal deformity were studied by magnetic resonance imaging (MRI). Sixteen patients had intraspinal abnormalities consisting of a tethered cord in 10, diastematomyelia in four, diplomyelia in three, syringomyelia in four, a low lying conus in three, and a teratoma of the sacrum in one patient. In seven patients, intraspinal anomalies were suspected based on routine spinal radiographs and physical findings. We recommend MRI in patients undergoing spinal stabilization procedures and in all patients with Lumbosacral kyphosis and those with pain, neurologic findings, or cutaneous hairy patch.

摘要:

We defined the natural history of scoliosis in congenital heart disease (CHD) with respect to the risk of progression and indications for treatment. We reviewed radiographs of 48 children with CHD and scoliosis. Thirty-seven had developmental scoliosis (77%), and 11 (23%) had congenital scoliosis. Children with congenital scoliosis can be managed in the same way as children without CHD. Developmental curves < 30° in children aged > 10 years showed no progression. Developmental curves > 30° with onset in children aged < 10 years and progression > 9° per year require treatment.
