Purpose: The authors used arthroscopy-assisted percutaneous reduction and cannulated screw fixation rather? than conventional arthrotomy for displaced glenoid fracture. Materials and Methods: We used arthroscopy assisted reduction and screw fixation for a 66 year old man who had a clavicle fracture, a displaced glenoid fracture and a scapula fracture. Results: At 9 months postoperatively, the patient had recovered full range of motion and was not inconvenienced by the surgery. Removal of the implant was done 12 months post-operatively under general anesthesia. Conclusion: The advantages of arthroscopy-assisted percutaneous screw fixation are less pain and less bleeding, shorter hospital stay and earlier rehabilitation. Arthroscopic percutaneous screw fixation for a displaced glenoid fracture seems to be a good alternative treatment method.

Femoral avulsion fracture of posterior cruciate ligament (PCL) is rare, especially in adult. We experienced a case of femoral bony avulsion fracture of PCL. The patient was seventy one year old man with limitation of motion in the knee joint due to previous trauma and he was injured by fall down from 2 m height. We took CT scan and MRI study. We treated with arthroscopic repair technique using transfemoral two wire sutures. Second look arthroscopy was done for removal of the wires at postoperative one year.

Objective : The purpose of this study was to evaluate the clinical and radiological results after treatment of old ACL(anterior cruciate ligament) avulsion fracture of tibia. Materials and Method : 11 cases who were followed up at least 2 years after treatment in chronic ACL avulsion fracture of tibia were included in this study. The average age of patients was 26(9-66) years and the mean period of follow up was 53(24-131) months. After evaluation of the lesion and treatment of associated lesion under arthroscope, open reduction and internal fixation or fragment removal was performed. Pull-out suture was performed in 8 cases, screw fixation in 2 cases. Results : The Lysholm knee score was 64.3 in average preoperatively and improved to 96.2 average at follow up. On the Lachman test, there were mild(+) instabilities in 7 cases, moderate(++) in 4 cases. On the postoperative Lachman test, there were no instabilities in 9 cases, mild(+) instabilities in only 2 cases. According to Meyers and Mckeever's evaluation protocol, 9 cases $(81.8\%)$ were excellent, 2 case $(18.2\%)$, good. On preoperative instrumented anterior laxity test with $Telos^{\circledR}$, side to side difference in 201b was 7.8(10-4) min in average and 2.1(6-0) mm in average at follow-up. Conclusion : In chronic ACL avulsion fracture, it is thought that combination of arthroscopic evaluation of associated injury and open reduction and fixation and fragment removal can bring about satisfactory results.

Objective : Percutaneous lumbar approaches such as arthroscopic discectomy, laser discectomy, and nucleotome remain controversial and have technical limitations to free fragment disc, bony pathology and access to L5-S1, The purpose of this study was to determine efficacy of this new endoscopic system and to report techniques and tactics. Methods : From July 1997 to May 1998, we treated 40 consecutive patients(43 levels) with the MED system. Mean age was 32 years(range ; 18 to 62). There were 30 males and 10 females. All patients had sciatica with SLRT limitation. There were 23 patients with disc herniation at L4-5 and 14 patients at L5-S1. Three patients had 2 level disc herniations. There was one far lateral disc herniation at L4-5. Results : Using modified MacNab criteria, there were 37 excellent results and 3 good result. Most patients were discharged within 3-4 days except 2 patients with dural tearing. There were no other complications. Mean operation time was 1.5 hours(range : 40 minutes to 2.5 hours). Conclusion : The MED system is a reliable approach to lumbar disc herniations. This system combines the advantages of conventional open surgery and a minimally invasive technique. As tactics for the doctors who wish to attempt, "palpate" the lamina by first dilator, identification of interlaminar space by removal of overlying soft tissue and confirmation of the shoulder portion of nerve root before discectomy are important to this procedure. We conclude that lumbar disc herniations can be successfully treated with MED approach.

Purpose: The purpose of this study was to evaluate the radiologic and clinical outcomes after intercalary tricortical iliac bone graft with plate fixation for the nonunion of midshaft clavicular fractures. Material and Methods: Between September 2007 and May 2011, 10 patients who were treated by the intercalary tricortical iliac bone graft, with plate fixation for clavicle nonunion, were studied. The mean follow-up period was 30.7 (12~57) months. After the sclerotic bone was excised to the bleeding cortical bone, we interposed the tricortical iliac bone to provide structural support and restore clavicle length, and then fixed the plate and screws. The radiologic outcomes on the serial plain radiographs and clinical outcomes, according to UCLA, ASES and Quick DASH scores, were analyzed. Results: Bony union was obtained in all cases (100%) and the average union time was 18.4 (14~24) weeks. The average respective UCLA and ASES scores improved from 16.7 and 52.1 preoperatively to 27.4 and 83.6 postoperatively (p<0.05). The average Quick DASH score was 40.5, at the final follow-up. Complications were 2 shoulder stiffness, and one case had removal of device and arthroscopic surgery at 11 months, postoperatively. There were no implant failure or infection. Conclusion: Intercalary tricortical iliac bone graft, with plate fixation for the nonunion of midshaft clavicular fractures, is a good option that can provide structural support and restore clavicle length, as well as high union rate.

The report about equine anesthesias in Korea are very rare. This paper aimed at the mortality rate during anesthesia in Thoroughbred horses at Equine Hospital of Busan Race Park, KRA in South Korea from 2005 to 2010. Drugs used in anesthesia was IV injection of detomidine hydrochloride (0.01 mg/kg) or xylazine(0.5mg/kg) for sedation and premedication, Guaifenesin(50-100 mg/kg) for muscle relaxation, ketamine hydrochloride(2 mg/kg) for induction of anaesthesia and Inhalational isoflurane(1.3-1.5 %) to maintain anesthesia. Total number of anesthetic cases was 190, 150 of inhalational anesthesia and 40 of general anesthesia, repectively. The purpose of anesthesia was highest in the disorder of musculoskeletal system, followed by urogenital system and respiratory system Mortality case due to anesthesia was one during arthroscopic surgery for removal of osteochondral chip fragments. The time of anesthesia was 150 min, fatal sign was hypoxemia and the reason was improper machine operation of the anesthetist. In conclusion, the perianesthetic mortality rate during anesthesia in Thoroughbred horses at Busan Race Park was 0.52%(1 death per 190 anesthetics).
