The correction of scoliosis induced by pure lumbar flexion was compared with the correction with the so-called Boston Thoracic Brace. Ten patients with idiopathic scoliosis were studied. There were 11 primary curves (31 +/- 6 degrees) (mainly thoracic) and four secondary curves (22 +/- 1 degree). Pure lumbar flexion reduced the primary curves by 6 +/- 2 degrees and the secondary curves by 8 +/- 3 degrees. The brace reduced the curves by 16 +/- 6 degrees and 14 +/- 5 degrees, respectively. Lumbar flexion per se produces a correction of the scoliosis of the same degree as the Milwaukee brace. Our results emphasize the importance of reduction of the lumbar lordosis in the conservative treatment of scoliosis.

Thoracic kyphosis was measured on chest radiographs of 316 "normal" subjects by means of a modification of the Cobb technique for measuring scoliosis. Patients were accepted as "normal" if they had no thoracic or spinal complaints or radiographic abnormalities in the chest including the thoracic spine. A total of 159 males and 157 female subjects 2-77 years old was studied. The relation among age, gender, and kyphosis were determined using least squares fits of first-order linear mathematical models. These results were also used to determine the expected ranges of kyphosis for a "normal" patient of a given age and gender. The degree of kyphosis increased with age and the rate of increase was higher in females than in males. Clinical explanations for this differential increase are discussed.

We conducted a radiographic retrospective study in children to determine spinal lordosis and kyphosis. A total of 218 lateral standing full-length radiographs were studied: 104 normal and 114 scoliotic patients. Normal X-ray films were defined as those obtained for suspected disorder (e.g., scoliosis) with no abnormalities detected by the radiologist or orthopedist. Thoracic kyphosis is defined as the angle between perpendiculars drawn from the inferior endplate of T5 and the superior endplate of T12. Lordosis is the angle between perpendiculars from the inferior endplate of L1 and the superior endplate of L5. The angle between the inferior endplate of L5 and the top of the sacrum is the L5-S1 angle. Statistical analysis was undertaken to compare lordosis and kyphosis radiographic measurements with age, sex, height, and weight employing the SAS package program. No significant relationships were noted between degree of scoliosis, age, sex, height or weight, and kyphosis, lordosis, or L5-S1 angle. Neither could correlations among the three radiographic measurements be made. Lordosis measured 40 degrees (range 31-49.5 degrees) in normal and 48.5 degrees (range 40-55 degrees) in scoliotic patients. Kyphosis measured 27 degrees (range 21-33 degrees) in normal and 28 degrees (range 16.5-36 degrees) in scoliotic patients.

The Boston Thoracic Brace, i.e. a Boston Brace without superstructures, has been used for treatment of scoliosis in 57 patients with 91 major curves measuring 31.8 +/- 6.5 degrees, the apex of the scolioses varying from D 7 to L 3. There was a mean correction of 12.9 +/- 6.4 degrees (41 per cent), which was superior to that of the Milwaukee Brace also in the thoracic scolioses (mean correction 3.6 +/- 5.8 degrees) (10 per cent).

A spinal pantograph - a non-invasive method for describing and documenting the posture of the back in the standing position - is described. Thoracic kyphosis and lumbar lordosis can be recorded by a simple technique. A comparative study of the range of kyphosis and lordosis measured by X-ray and this mechanical device shows a statistically significant correlation. As regards the thoracic kyphosis, the spinal pantograph seems to be as accurate as the X-ray. In lumbar lordosis an underestimation is seen with the clinical device. Compared with non-scoliotic cases, a significantly decreased kyphosis is observed in structural scoliosis, even in cases with a scoliotic angle of less than 30 degrees according to Cobb. The advantage of this spinal pantograph is that it reduces the radiation dosage. It can be used for screening and follow-up examination of the posture especially during the growing stage.

Long-term domiciliary ventilation is an effective treatment for chronic hypoventilation due to neuromuscular disease or thoracic deformity. As the majority of patients require assisted ventilation only at night, it is a simple means of improving quality of life, and even sometimes of prolonging life. According to a nationwide enquiry organised by the Swedish Thoracic Society in 1993, 460 patients (5.5 per 100,000 of the population) were using domiciliary ventilation (almost a doubling of the figure of 250 patients reported from a similar survey in 1990). The most prevalent indications were poliomyelitis sequelae (30%), followed by myopathy (21%), idiopathic scoliosis (13%) and tuberculosis sequelae (13%). Eighty per cent of the patients used assisted ventilation only at night, and 60 per cent used non-invasive devices such as a nasal mask.

Thoracic abnormalities and respiratory muscle function were investigated in nine patients with rigid spine syndrome. A severe restrictive chest wall defect and limited mobility of the spine associated with clinically significant respiratory muscle weakness were present in all patients. Respiratory muscle strength and endurance were less than 60% of control values. Slight to moderate scoliosis was present in five patients and absent in four. Scoliosis appeared to have only a minor additional effect on respiratory muscle function. Six patients were emaciated, and one patient was underweight, but no relationship was seen between body mass index and respiratory muscle strength. Respiratory muscle function was more impaired in patients with hypoventilation than in normocapnic patients. Respiratory muscle involvement appears to be a significant feature of rigid spine syndrome, terminating in hypercapnic ventilatory failure in some patients.

Radiographic outcome and complications of Harrington-DTT (H) and Cotrel-Dubousset (CD) instrumentation of idiopathic adolescent thoracic scoliosis were compared retrospectively. The patient material consists of 55 consecutive patients in the H group and 52 consecutive patients in the CD group. The mean age at operation was 15 +/- 2 years (range, 11-19 years) in both groups. The follow-up interval was 43 +/- 18 months (range, 17-91 months) in the H group and 28 +/- 11 months (range, ten to 53 months) in the CD group (p = 0.0001). The preoperative radiographic measurements (Cobb angle of primary and secondary curve, apical rotation, thoracic kyphosis, lumbar lordosis) were fully comparable in both groups. The mean correction of the primary curve at the follow-up evaluation was 47% in both groups. Apical rotation of the primary curve remained almost unchanged in both groups. Rotation of the secondary curve increased significantly in the CD group. Thoracic kyphosis was unchanged in the CD group but decreased in the H group. Spinal balance worsened in 29% of the H cases and in 44% of the CD cases. There were no neurologic complications in either of the groups. Intraoperative lamina fractures (four cases) and postoperative hook dislodgement (five cases) occurred only in the CD group. One distraction rod breakage occurred in the H group. Three reoperations were performed in the H group, nine in the CD group.

Twenty-six patients who underwent Wisconsin instrumentation and 36 patients who underwent Cotrel-Dubousset instrumentation (CDI) for idiopathic scoliosis were studied. Inclusion in the study required at least 24-month follow-up. Variables compared included operating time, blood loss, frontal plane correction, axial and sagittal plane changes, effects on compensation, and complications. In general, operating time, blood loss, and instrumentation problems were greater with CDI. Thoracic curve correction in King II curves was better with CDI. There was no advantage to either system with respect to sagittal plane alignment or rotation. When all factors were considered, a significant advantage to use of CDI could not be demonstrated.

Donor-site complications, specifically chest wall deformities and thoracic scoliosis, occurring after harvest of costal cartilage grafts are presented and discussed. The cases of 18 patients (12 male and 6 female), who underwent costal cartilage grafts for microtia reconstruction from 1975 to 1993, were reviewed for donor-site complications using radiography and physical examination. Ribs from which costal cartilage had been harvested showed increased inward bowing on radiographs in 16 of 32 donor sites. The frequency of rib deformity in donor sites was 20.0 percent when cartilages were harvested from patients older than 10 years of age, whereas it was 63.6 percent in patients younger than 10 years old. This difference was statistically significant (p = 0.027, Fisher's exact test), although only 32 grafts were performed in 18 cases. The upper ribs demonstrate a higher incidence of deformity than lower ribs. Thoracic scoliosis was found in 4 of 16 cases. The biomechanical impact of these deformities was considered because of respiratory movement of the thorax and injury to the germinal growth center of the ribs. We recommend delaying costal cartilage grafts for as long as possible, leaving the costochondral junction intact to minimize chest wall deformity and thoracic scoliosis.
