Objective To report the preliminary experiences in the treatment of old unstable thoracolumbar vertebral fractures by using anterior decompression, bone graft or titanium mesh and internal fixation with Z-plate system. Methods There were 23 cases (18 males and 5 females) with age range of 25-66 years (mean 41.7 years) as well as thoracolumbar vertebral fracture history for 1.2-28 years (mean 5.6 years). All cases complained of severe lower back pain, 17 of whom had slight neurological deficits (Frankel Grade D). Preoperative radiographic evaluation showed that all 23 cases had various degrees of kyphosis (25?-40?, averaged 34?), spinal cord compression and vertebral instability. Of 23 cases, 15 were treated with anterior decompression, full-thickness iliac crest autograft and internal fixation with Z-plate and the other 8 with titanium mesh instead of full-thickness iliac crest autograft. Results No severe complications happened during and after operation. The lower back pain and neurological deficits were improved or disappeared 2-3 months postoperatively. The average kyphotic correction degrees ranged from preoperative 34? to postoperative 12?. No patients' symptoms worsened during follow-up. In three cases with preoperative Frankel Grade D, the myodynamia recovered slightly but the Frankel Grade remained unchanged. The postoperative MRI examinations showed that vertebral canals were well decompressed. Conclusions Anterior decompression, autograft or titanium mesh and internal fixation with Z-plate are proved to be safe and effective techniques for clinical management of old thoracolumbar fractures, for they have advantages in effective decompression of neural structures, high healing rate of autograft and correction of kyphotic deformity.

Objective To explore the methods and clinical results of the arthroscopic acromioplasty for the treatment of impingement syndrome of shoulder. Methods 15 cases with impingement syndrome of shoulder were studied. There were 9 males and 6 females. 10 right shoulders and 5 left ones were involved. The average age of patients was 47 years ranging from 32 to 54 years. 3 injuries were classified as degree I, 4 as Ⅱ, and 8 as Ⅲ according to Neer classification. All the patients had a chronic injury and painful history around shoulder. The positive arch pain test was presented in 12 cases and impingement test in 13 cases. 13 patients had been received MR examinations, and 5 arthrographies of the shoulder. The AP and the supraspinatus outlet projection of the X-rays were obtained before surgery. The procedure of arthroscopic acromioplasty consisted of 5 following steps: the first was arthroscopic subacromial inspection with posterior portal; the second was subacromial bursectomy with electro-shaver or burr; the third was release or resection of the coracoacromial ligament with electrocautery; the fourth was subacromial decompression with full-radius resector or burr; and the last was debridement of the soft tissue around the acromio-clavicular joint and resection of the the spurs. 4 patients underwent reparation of the rotator cuff simultaneously. Results All cases were available for follow-up. The average time was 15 months. According to the UCLA scoring system, the average score was 18.5?8.2 and 31.7?6.5 pre- and post-operation respectively; the difference was of statistical significance(t=3.35, P

OBJECTIVETo summarize the therapeutic effect of 5 kinds of flaps for the treatment of skin and soft tissue defect in the hallex.
METHODSFrom Jan. 2008 to Jun. 2013, 24 cases with skin and soft tissue defects in the hallex were treated with 5 kinds of reversed flaps, including medial foot dorsal neurocutaneous flaps, medial foot neurocutaneous flaps, lateral tarsal flaps, anterior malleous flaps, medial cross leg and saphenous nerve flaps. The defects size ranged from 3 cm x 2 cm to 5 cm x 3 cm, with the flap size from 3. 5 cm x 2. 5 cm to 5. 5 cm x 4. 0 cm.
RESULTSPartial superficial necroisis happened at the distal end of one foot dorsal medial neurocutaneous flap. One third flap necrosis occurred in 1 foot medial neurocutaneous flap due to too tight suture at flap pedicle and resulted thrombosis. All the other 23 flaps survived completely. 15 cases were followed up for 3-36 months with normal walking function and satisfactory appearance. Among the 8 cases with nerve anastomosis, 4 cases were followed up with 2-point discrimination distance of 8-11 mm. the flaps without nerve anastomosis also had protective sense due to nerve ingrowth.
CONCLUSIONSSkin and soft tissue defects in the hallex can be treated with different appropriate flaps. The hallex length can be reserved with satisfactory function and appearance.

Objective To reduce the occurrence of recurrent choledocholithiasis caused by biliary sphincter dysfunction after extensive endoscopic sphincterotomy ( EST ) for large stone extraction, and to investigate the sphincter-preserving effects of duodenal papilla occlusion by SureClip from MicroTech. Methods Three patients with large biliary stones ( 1. 0-2. 5 cm in stone size, 1. 2-3. 0 cm in common bile duct diameter) and without ERCP history underwent EST ( larger than 1. 0 cm) in Peking University Third Hospital from March 2018 to May 2018. Biliary and pancreatic stents were placed after stone extraction, followed by duodenal papilla occlusion with SureClip from MicroTech. Pressures of biliary duct and Oddi sphincter were measured at pre-EST, immediately after EST, and when stents were removed 3 weeks after EST, respectively. Healing conditions of papilla and complications were documented. Five pigs underwent similar experiments without stone extraction. Results The pressure of Oddi sphincter was significantly reduced after EST, and recovered after papilla occlusion 3 weeks after operation both in pigs and human. All stones were completely removed in the 3 patients without any post-ERCP complications. The papilla was healed under endoscopic observation when stents were removed 3 weeks after papilla occlusion. In animal experiments, histology revealed completely muscularis propria disruption of post-EST papilla without occlusion. In contrast, the muscle layer of post-EST papilla with occlusion by SureClip from MicroTech appeared scar healing. Conclusion The duodenal papilla occlusion by SureClip from MicroTech after EST works as "papilla remolding", which accelerates healing of papilla, and retains the sphincter pressure and anti-reflux barrier function.
