ABSTRACT
ObjectiveTo explore puncture point and angle of skin for unipedicular vertebroplasty by imaging measurement and combining clinical practice in order to pr vide reference for clinical work.MethodsCT images of thoracic and lumbar vertebrae of imaged with multislice helical CT were random chosen.From high to low position vertebrae of easy fracture T6 to -L5,its angle between vertebraI pedfcle stalk line and 1/3 of vertebraI body stalk line fore and median of point of intersection was measured.The angle of sternocostal joints route was also measured.At the same time the distance between site of skin puncture and spinous process was measured.ResultsThe angle between the thoracic vertebraI pedicle and sagittal section was (28.2 ± 3.8) °,the lateral distance of the spinous process was ( 31.6 ± 5.4) mm.The angle of thoracic vertebraI pedicle lateral route was (35 ± 3.4) °,the distance was ( 55.2 ± 5.3 ) mm.In the lumbar vertebrae pedicle route,the angle of L1 -L4 was (29.3 ± 5.6 ) °,the distance was (38.4 ± 4.5 )mm.Ls was (39.2 ± 3.3) °,the distance was ( 71.6 ± 6.2) mm.Combining clinical practice,the lateral distance of the spinous process in thoracic vertebraIpedicle route,the best puncture point was 30 mm,in thoracic vertebraI pedicle lateral route it was 40 mm,in L1-L4 it was 45 mm,in L5 it was 60 mm.ConclusionsThe unipedicular vertebroplasty can be performed rapidly,accurately and safely,and it reduces complications,cost and time.
ABSTRACT
ObjectiveTo investigate clinical efficacy of reconstructing for old anterior cruciate ligament(ACL) injury with quadruple hamstring tendon,and application value of femoral intercondylar notch plasty.Methods Fifty-six cases of old ACL injury were reconstructed arthroscopically with quadruple hamstring tendon.Forty-five cases were used femoral intercondylar notch plasty.Preoperative Lachman test were positive,and ACL injury were confirmed by MRI.The curative effect was evaluated according to Lysholm knee score and KT-1000 measurement results.ResultsAll of the 56 patients were followed up for 6-24 (13.0 ± 4.2) months.Postoperative Lachman test of 53 cases were negative,and 3 cases were weak positive.The Lysholm knee score increased from preoperative (56.0 ± 7.3) scores to postoperative (93.0 ± 3.5 ) scores,comparison of preoperative had significant difference (t =34.20,P ＜ 0.01 ).The postoperative KT-1000 measurement showed ＜ 3.0 mm side difference of anterior laxity,moving average of(2.0 ± 0.6) mm,comparison of preoperative ≥ 3.0 mm,moving average of (3.0 ± 1.2 ) mm had significant difference (t =5.58,P ＜ 0.01 ).ConclusionsArthroscopic reconstruction of ACL with quadruple hamstring tendon have a good effect.The postoperative rehabilitation exercise can practise early.The femoral intercondylar notch plasty which used during operation is benefit of decreasing femoral intercondylar notch impingement syndrome,accurate positioning femur tunnel,and increasing curative effect.
ABSTRACT
Objective To explore the features and treatment methods of osteoporotic vertebral compression fracture of elderly patients with cardiopulmonary diseases. Methods 18 cases of osteoporotic vertebral compression fracture of elderly patients with cardiopulmonary diseases teated by percutanteous vertebroplasty(PVP), and VAS(visual analogic scale) and mobility ability were measured before and after treatment. Results All 18 patients were punctured and operated successfully. The preoperitive and postoperative VAS was 7.6?1.2 and 3.7?1.3, respectively. There was obvious pain relief after operation (P
