[Objective]To study the efficacy and related problems of lumbar microdiscectomy and small-incision discectomy in the treatment of lumbar disc herniation.[Method]A total of 82 cases were treated with lumbar microdiscectomy,70 cases were treated with small-incision discectomy.The results of two groups were compared.[Result]Compared with the small incision group,the operative time and the complication rates were significently reduced.The effective rate between the two groups had no significent difference.[Conclusion]Small-insion discectomy is as an effective operation as microdiscectomy,while lumbar microdiscectomy had the advantages of minimal invasive,more indications,less bleeding.Strict selection of indications,sufficient preoperative preparations and practiced surgical techniques are the key points of the two minimally invasive techniques to award good outcomes.

[Objective]To oberserve the method and efficacy of anterior microsurgical decompression and fusion via cervical disc space in the treatment of cervical spondylotic myelopathy.[Method]Forty-three patients were treated with microsurgical decompression via cervical disc space and fusion with PEEK(Polyetheretherketone)cages.Preoperative,immediate postoperative and follow-up X-ray films were utilized to oberserve the fusion rate of the segments,and to evaluate the restoration of lordosis(Cobb's angle)and intervertebral height.[Result]All patients were followed up with an average of 15.4 months.The fusion rate was 100% and the satisfactory rate was 88.4% according to the 40 score method.Immediate postoperative X-ray films showed 6.0?improvement in lordosis(P

Objective To evaluate the method and clinical effect of subtalar joint distractor assisted open reduction and internal fixation of comminuted intra-articular calcaneal fracture.Methods Twenty-two patients with fresh closed calcaneal fracture treated with open reduction and internal fixation from May 2011 to July 2013 were included in the study.According to the modes of operation,the patients were randomly divided into two groups (n =11 in each):in group A patients underwent fracture reduction assisted by subtalar joint distractor and in group B patients underwent Steinmann pin traction and poking reduction.All were fixed using the lateral calcaneal plate.Operation time,B(o)hler angle,Gissanes angle,calcaneus height,incision healing time and complications of the two groups were investigated for evaluating the effect of operation.Clinical effect was evaluated using the American Orthopedic Foot & Ankle Society (AOFAS) score before the removal of internal fixation.Results Period of follow-up was (14.3±0.8)months (range,12 to 18 months).Two patients in group B had delayed wound healing,and were treated with regular wound care.At the final follow-up,no infection,nonunion,malunion and internal fixation failure were observed.B(o)hler angle,operation time and calcaneus height observed in group A were superior to those in group B (P ＜0.01).There was no significant difference in Gissanes angle between the two groups (P ＞ 0.05).Compared to the preoperative data,B(o)hler angle,Gissanes angle and calcaneus height were significantly improved in both groups (P ＜0.01).AOFAS score was (83.6 ± 1.4) points in group A and (81.7 ± 1.5) points in group B.Conclusion Subtalar joint distractor assisted open reduction and internal fixation is effective to shorten operation time,improve fracture reduction,reduce wound complications and increase the operative effect for comminuted intraarticular calcaneal fracture.

Objective To investigate the clinical efficacy of fixation of distal radius fracture with dorsal instability with locking compression plate (LCP) via radial approach.Methods From September 2009 to October 2012, 21 cases underwent LCP fixation of the distal radius fracture with dorsal instability via radial approach.The study included 14 males and 7 females (mean age, 54.5 years;range, 38-81 years).Twelve cases were injured in traffic accidents, 7 in falls and 2 in high falls.Fracture AO classification was type A3 in 10 cases, type C1 in 8 cases and type C2 in 3 cases.Two cases (one type A3 and one type C1) had malunion.When the lateral column, intermediate column, radial edge and dorsal plane were exposed by radial incision, LCP fixation with bone grafting was performed to restore the height of radial styloid process, ulnar deviation and palmar tilt.According to the GartlandWerley score, wrist joint function was evaluated.Results Mean duration of follow-up was 13.5 months (range, 12 to 24 months).Stage Ⅰ bone union was shown on X-rays, with the healing time of 7.5 weeks.Based on the X-rays at postoperative 6 months, 1 year and 2 years, the shortening of radial styloid process was ≤ 2 mm, mean volar tilt was 12.5°(range, 8°-17°) , mean ulnar tilt was 20.5° (range, 15°-26°), and step-off or gap of the articular surface was ≤ 2 mm.In postoperative wrist motion assay, mean volar flexion was 60°(range, 30°-70°), mean dorsal flexion was 55° (range, 30°-65°), mean radial deviation was 17°(range, 10°-20°), mean ulnar deviation was 25.5° (range, 20°-30°),pronation was 65.5° (range, 60°-70°) , and mean supination was 75.5° (range, 60°-80°).Mean grip strength was 75％ (60％-95％)of the contralateral side.Two cases suffered from pain (one complained of moderate pain and one minor pain occasionally).According to the Gartland-Werley score, 16 cases were rated excellent, 2 good, 2 fair and 1 poor, with the excellent rate of 86％.No complication was found as injury of the superficial branch of radial nerve, infection, nonunion, nail loosening, medium neuritis and tendon injury.Conclusions Lateral column, intermediate column, radial edge and dorsal plane can be shown via the radial approach.LCP fixation combined with bone grafting contributes to fracture anatomical reduction.

Data of patients with maxillofacial and jugular venous malformations involving isthmus faucium area from January 2012 to July 2016 were collected. Patients were questioned about the medical history before operation, and the airway was adequately evaluated. The patients diagnosed as having non-difficult airways were endotracheally tubed using fast induction of anesthesia. Tracheal intubation was per-formed using fast induction of anesthesia combined with topical anesthesia after visual laryngoscopy in the patients assessed as having difficult airways. Endotracheal intubation was guided with a visual hard endo-scope or a fibrobronchoscope in the patients with difficulty in opening mouth after multiple treatments. Post-operative airway management was as follows: the tracheal tube was removed after extubation, the tracheal tube was retained for 24-48 h, or preventive tracheotomy was performed. Oxygen was inhaled by mask. A total of 157 patients were included in this study, 55 patients diagnosed as having difficult airways, and a-mong the 55 patients, 87％ cases were intubated after visual laryngoscopy and 13％ cases received tracheot-omy. There were 10 patients with difficulty in opening mouth after multiple treatments and 5 cases under-went tracheotomy in the outer hospital. Sixteen patients presented with a transient increase in airway pres-sure during intraoperative injection of anhydrous ethanol. There were 106 cases in whom the tracheal tube was removed immediately after emergence, and among them, 32. 1％ cases needed tongue traction and 2. 8％ cases underwent emergency tracheotomy after extubation. Thirty-eight patients needed to retain the tracheal tube for 24-48 h after operation, and among them, 37％ cases needed tongue traction and 3％ ca-ses required emergency tracheotomy after extubation. Thirteen cases underwent preventive tracheotomy. The preoperative visit and assessment are especially important, appropriate airway management strategies should be developed, vital signs should be closely observed during operation, and the timing of extubation should be grasped for this type of patients, and the SpO2 and airway pressure should be mainly observed during op-eration especially for the patients who underwent anhydrous ethanol injection.
