Thoracoplasty has been described as primarily a cosmetic resection of the rib hump. The purpose of our study was to investigate whether removal of a normal spine stabilizer affected the correction of the spine, particularly in the sagittal plane. Thirty-eight adolescent idiopathic scoliosis patients who underwent thoracoplasty were compared with eighteen controls in terms of maintenance of correction and patient satisfaction using the SRS questionnaire. Thoracoplasty had no effect on curve correction in the coronal plane. It did show a significant effect on sagittal plane correction of the thoracic hypokyphosis without any significant detractors in terms of patient outcome To investigate whether thoracoplasty affected spinal correction. We also compared patient outcomes thoracoplasty patients and controls, as well as long-term curve maintenance. Thoracoplasty did increase the correction of thoracic hypokyphosis, without any significant detractors in terms of patient outcome. Current understanding of the scoliotic curve as a three dimensional helix has led to increased recognition of the importance of sagittal contour and balancing the spine’s reciprocal curves to avoid problems such as flat back syndrome. Correction of the scoliotic curve intraoperatively may require the removal of spine stabilizers such as the disc and annulus, posterior facet and capsule, and thoracic cage stabilizers such as the ribs. Thirty-eight patients who had either concave para-median or convex Steel mid-rib thoracoplasty were reviewed and compared to eighteen controls. Prospective patient outcomes using the Scoliosis Research Society instrument with an average of >
one year follow-up were available for thirty patients. Degree of curve settle and maintenance of correction was measured on follow-up radiographs. Thoracoplasty had no effect on curve correction in the coronal plane. It did show a significant effect on sagittal plane correction of thoracic hypokyphosis. The paramedian group showed a mean increase of tweleve degrees, the Steel group 8.7 degrees, and, the control group 3.1 degrees. No significant difference between pain, satisfaction, function, and self-image was found. Long-term radiographic follow-up (average three years) showed a mean coronal curve settle of 4.6 degrees (thoracoplasty) versus 3.1 degrees (non-thoracoplasty), and an accompanying improvement in sagittal plane correction of 4.2 and 3.0 degrees, respectively.
Twenty-one symptomatic flat feet from the surgical wait list were compared with twenty-one matched controls. The radiographs were digitized, blinded and the measurements made two occasions by two observers in different order. On the lateral radiograph the talar to first metatarsal angle reached greatest significance at p<
0.0001, and had an inter and intra observer reliability of 0.83 and 0.75 respectively (r2 value). Only three other of the twelve measurements made reached statistical significance. Radiographic assessment of reconstructive procedures should show restoration of the arch of the foot: We recommend using the talar neck to first metatarsal angle on the lateral view as the correct indicator of loss or restoration of an arch. The purpose of this study was to determine the radiographic measures that differentiate the symptomatic adult flat foot from a normal foot, and determine the reliability of the measurements. Although many radiographic measures of flat foot are described, only four out of twelve measurements studied were significantly different between symptomatic adult flat foot and normal adults. Radiographic assessment of reconstructive procedures should show restoration of the arch of the foot: We recommend using the talar neck to first metatarsal angle on the lateral view as the correct indicator of loss or restoration of an arch. Twenty-one symptomatic flat feet from the surgical wait list were compared with twenty-one matched controls. Diagnoses included rheumatoid arthritis and posterior tibial tendonitis. All previously described measures of loss of arch were measured on standing AP and lateral radiographs of the foot taken using the same radiographic technique at a single facility. The radiographs were digitized, blinded and the measurements made two occasions by two observers in different order. On the lateral radiograph the talar to first metatarsal angle reached greatest significance at p<
0.0001, and had an inter and intra observer reliability of 0.83 and 0.75 respectively (r2 value). The medial cuniform to 5th metatarsal height also reached signficance, but had poor intraobserver reliability (r2 =0.09). On the AP view, only the talar head uncoverage distance reached significance (p<
0..0001) but had poor inter and intraobserver reliability (r2
The purpose of this study was to investigate the effects of varying tire pressures on rolling resistance of pneumatic wheelchair tires and compare the rolling resistance of pneumatic versus solid wheelchair tires. Our study demonstrated that, statistically significant increases in rolling resistance occurred at and below 50% of the recommended tire pressures (RTP) for the pneumatic tires tested. Also, solid tires performed worse than pneumatic tires at 25% (RTP). Shoulder pain among the spinal cord injured wheelchair users is reported between 60–100%. Despite the shoulder problems, it’s not uncommon to see WC users with low or flat tires. To reduce the need for regular inflating of tires, people have switched to the popular solid tire. Unfortunately, based on our results, the use of the popular solid tires may still contribute to repetitive strain disorders in wheelchair users. Compared to the recommended tire pressures the pneumatic tires showed statistically significant decreases in rolling distance at 25% and 50% RTP. The rolling distances of the two solid tires performed similarly to 25% RTP of the pneumatic tires. This prospective study measured the differences in rolling resistance of five types of commonly used wheelchair tires (three pneumatic: two solid: under four different tire pressures (100%, 75%, 50% and 25% RTP) using a standardized roll down test ramp and a wheelchair with a 56 kg load. Four samples of rolling distances (five per tire pressure per sample) were measured for each tire type and analyzed (repeated measure ANOVA).
