Résumé
Adolescent scoliosis is spinal deformity happening in early adolescent or before bone mature.It can affect the body figure and appearance of children,threat the physical and mental health of the youth.Serious malformation even leads to heart and lung function failure.This paper summarizes the causes of disease incidence,the incidence situation in domestic and abroad,census method,the latest gene chip technique,the latest progress of treatment,and investigates the method of early prevention,early diagnosis,and early treatment.For younger children,non-surgical treatment such as brace could be used to avoid scoliosis aggravating.
Résumé
In this study the relation between the extent and type of disc protrusion and the clinical severity of symptoms of low back pain was observed. Our series consisted of 300 consecutive cases of lumbar disc protrusion,with their diagnosis confirmed by intraoperative observation. Preoperative pain severity was assessed using a back pain scale that combined the symptoms of back pain and sciatica. Intraoperaative pathological findings of disc were documented and comparesd with preoperative symptoms and signs. The pathological changes of disc were classified as following four subtypes: bulging disc (85 cases), protruding disc (104 cases), extruded disc (72 cases) and sequestered disc (39 cases). Our results suggest that severity of pain in patients with herniated lumbar disc is related to position of herniation rather than magnitude and exent of herniation. Inflammed intraspinal tissues are significantly associated with low back pain and sciatica.
Résumé
Multi-segmental posterior osteotomy of the spine was performed upon 12 patients with ankylosing spondylitis for the correction of kyphosis. The deformity was situated in thoraco-lumbar spine in 11 cases and lumbar spine 1 case. The magnitude of the curves ranged from 55 to 110 Cobb's degrees with a mean of 81 degrees. The number of osteotomy was 5.4 in average (3-7 segments). The highest level of osteotomy was T7 and the lowest L5. The average correction was 49.5 degrees (61%) with a range of 30-80 degrees. No severe complication was found in our series. This procedure may disperse the effects of osteotomies over the whole curve with its center at the apex of the curve, and it carries the following advantages: (1) direct correction is mechanically efficient and causes a better external appearence with less correction; (2) it may restore the physiological curves and normal weight-bearing line of the spine; (3) it entails solittle influence on the stability of the spine that it is unnecessary to give extra support; (4) it may reduce the opening up of each intervertebral space, avoiding the overstretching injury of the viscrae and blood vessels.
