RESUMO
Objective To introduce the treatment efficacy of using allograft muscle ligament anatomical to rebuild anterior cruciate ligament (ACL) of knee joint under the arthroscopy.Methods Sixty-two cases patients with ACL rupture in anterior cruciate ligament reconstruction under arthroscopy.Allograft ligaments were used as graft,a bone tunnel was established in the proximal tibia and distal femur,and the graft was fixed by the extrusion screw.After the operation,the knee joint was fixed for 12 weeks,and the subjective evaluation was carried out according to the Lysholm and Larson knee score standards;in order to assess the stability of the ligament and the functional recovery of the knee joint,objective evaluation was carried out according to Lachman test in patients.Results The preoperative average Lysholm scale was (43.1±2.1) points,the final average score of 2 years after the reconstruction of the ligament was (91.0+2.3) points,there was significant difference (t=3.460,P=0.001).The preoperative average Larson scale was (41.0±2.9) points,the final average score of 2 years after the reconstruction of the ligament was (90.1±3.5) points,there was significant difference (t=3.232,P=0.001).Lachman test results were negative in 62 patients at the end of the review.No serious postoperative complications occurred,no knee infection,deep vein thrombosis and stiffness.All the patients can be completely straight 1 year after operation,knees up to 120 degrees.All patients were satisfied with the function at the end of the follow-up,no joint instability,no re-rupture occurred during the follow-up period.Conclusion Using the allogeneic single beam anatomy of anterior cruciate ligament reconstruction under arthroscopy can obtain satisfactory clinical efficacy.
RESUMO
Objective To assess the clinical threatment results of pilon fractures managed with arthroscopyassisted minimally invasive percutaneous plate osteosynthesis (MIPPO).Methods 33 patients with pilon fractures were classified into 3 groups according to the Ruedi-Allgower classification:type Ⅰ in 26 cases,type Ⅱ in 5 cases,type Ⅲ in 2 cases,including 29 males and 4 females,aged 22 to 51 years,mean 31.5 years of age.All patients were treated with arthroscopy-assisted MIPPO with the postoperative follow-up time of 12 to 84 months.Results The clinical surgery efficacy according to Mazur's criterion was evaluated as excellent in 22 cases,good in 8 cases,fair in 3 cases.The excellent and good rate was 90.9％.Conclusion Arthroscopy-assisted MIPPO surgical treatment is an effective method for Pilon fractures with the advantages of good healing,minimal trauma and less complications,it is worthy of clinical application.
RESUMO
@#Objective To assess the efficiency of total laminectomy and transpedicular screw placement techniques and a thoroughly decompression with a three column fixation device on the early cervical spine cord injury.Methods 27 patients were operated successfully with total cervical laminectomy through transpedicular screw techniques.Precise measurements of all cervical spines were made by postoperative CT scan of pedicle dimensions,angulation,and offset relative to the lateral mass boundaries.And meanwhile,cortical integrity and neurovascular injury were then assessed by obtaining postoperative computed tomography scans of each patient.Results Using manual techniques,220 pedicles were instrumented and all the cases were followed up between three to twenty-four months.The postoperative gradations were obviously better than the preoperative evaluation.Regardless of the technique used,the vertebral artery was the structure most likely to be injured.Conclusion Insufficient correlation between different surgeons' assessments of surface landmarks attests to the inadequacy of screw insertion techniques in the cervical spine based on such specific topographic.At the early stage of cervical spinal cord injury,using total laminonectomy decompression through cervical screws techniques to reconstruct spinal alignment could improve the prognosis of patients.
