The technique of the arthroscopic total meniscectomy of discoid meniscus is very difficult. Ikeuchi(1982) reported a technique of arthroscopic total meniscectomy of the lateral discoid meniscus by removal of 2/3 of the anterior part of the meniscus first and then by morselization. The purpose of this paper is to report a technique of arthroscopic total meniscectomy of the lateral discoid meniscus as a whole. During the period from October 1982 to October 1984, we had 12 experiences of arthroscopic total meniscectomy of the discoid meniscus and found good results, that is, little postoperative pain, short period of hospitalization and early restoration of joint motion without physical therapy. Complications are 3 cases of symptomless slight lateral instability and 4 cases of hemarthrosis.

PURPOSE: This study was aimed to evaluate the recurrence rate of a giant cell tumor (GCT) of the bone. MATERIALS AND METHODS: The medical records of fifty four patients who were diagnosed with a giant cell tumor of the bone between March 1980 and December 2008 were analysed retrospectively. Among 54 patients, 27 were men, remaining 27 were women with the mean age of 33.1 years (range, 13-67 years). The mean duration of follow-up was 67.1 months. RESULTS: Twenty-one patients (38.9%) had a local recurrence. The mean time to recurrence was 21.5 months (range, 2-59 months). The local recurrence rate of the upper extremities was higher than that of lower extremities. According to Campanacci classification, patients with a grade I diseae had lower recurrence rate than those with grade II or III disease. There was no significant differences in the recurrence rates based on cryotherapy, the filling of bone cement or bone grafts and surgical margin. CONCLUSION: To prevent local recurrence of GCT of bone, curettage of the tumor and elimination of the remaining cells are more important than adjuvant therapy.

Trabeculectomy, as an operation precedure for glaucoman, decrease intraocular pressure(IOP)effectively. But the amount of decrease in IOP is different according to the etiology of glaucoma. Thirty four primary angle-closure glaucoma patients (37 eyes)who had undergone trabeculectomy only or trabeculecomy combined with cataract surgery and had been subsequently followed up for least 6 months, were enrolled in this study. In 12 patients(14 eyes) among 16 patients (18 eyes, Group 1) who had undergone trabeculecto-my only, IOP was controlled without glaucoma medication, while glaucoma medication was needed in the other 4 patients (4 eyes). Among 18 patients (19 eyes, Group 2) who had undergone trabeculectomy combined with cataract surgery, IOP were controlled without glaucoma medication 9 patients (10 eyes); controlled with medication in 8 patients (8 eyes); and not controlled even with 1 patient (1 eye). The amount of decrease in IOP was no statistically different between the two groups. Group 2 had deeper anterior chamber than Group 1 (p<0.01). The above results suggest that the combined pro-cedure may benefit in primary angle-closure glaucoma patients, especially old complicated patients.

Acute suppurative cholangitis is a severe inflammatory process of the bile duct occurred as a result of partial or complete obstruction of the bile duct, and may manifest clinically severe from of disease, rapidly deterioration to life-threatening condition. We analyzed emergency percutaneous transhepatic biliary drainage in 20 patients of acute suppurative cholangitis with biliary sepsis to evaluate the therapeutic effect and complication of the procedure. The underlying causes were 12 benign diseases(stones) and eight malignant tumors and among eight malignant tumors, bile duct stones(n=4) and clonorchiasis (n=1) were combined. Percutaneous transhepatic biliary drainage was performed successfully in 17 of 20 patients improvement of general condition and failed in three patients. The procedures were preterminated due to the patient's condition in two and biliary-porto fistula was developed in one. After biliary decompression by percutaneous transhepatic biliary drainage, effective and successful elective surgery was performed in nine cases, which were seven biliary stones and two biliary cancer with stones. Our experience suggests that emergency percutaneous transhepatic biliary drainage is an initial and effective treatment of choice for acute suppurative cholangitis with sepsis and a safe alternative for nonsurgical treatment.

BACKGROUND: Management of massive rotator cuff tears can be challenging because of the less satisfactory results and a higher retear rate regardless of the use of open or arthroscopic repair technique. METHODS: We retrospectively analyzed 102 cases of massive rotator cuff tear treated with either open or arthroscopic repair. Open repair was performed in 38 patients; and arthroscopic repair, in 64 patients. The mean age at the time of surgery was 59.7 years in the open group and 57.6 years in the arthroscopic group. RESULTS: The Constant score increased from the preoperative mean of 55.9 to 73.2 at the last follow-up in the open repair group and from 53.8 to 67.6 in the arthroscopic repair group (p<0.001 and <0.001, respectively). The University of California at Los Angeles (UCLA) score increased from a preoperative mean of 17.7 to 30.8 at the last follow-up in the open group and from 17.5 to 28.7 in the arthroscopic group (p<0.001 and <0.001, respectively). No statistically significant difference in the Constant and UCLA scores was observed between the two groups at the last follow-up (p=0.128 and 0.087, respectively). Retear was found in 14 patients (36.8%) in the open group and 39 patients (60.9%) in the arthroscopic group (p=0.024). CONCLUSIONS: Open and arthroscopic repairs of massive rotator cuff tears may provide satisfactory clinical results with no significant difference. However, a significantly lower retear rate was observed for the open repair group compared with the arthroscopic repair group.

There has been a series of reports indicating that scleral buckling[SB] surgery may induce high myopia in advanced retinopathy of prematurity. The mechanism of SB on refraction, however, has not been clearly known. We investigated the effects of SB on eyeball in young rabbits, including mechanism of refractive change. In 9 rabbits with 5 weeks old[Group A]and 11 rabbits with 8 weeks old[Group B], SB was performed for right eyes of all rabbits with encircling band, 2.5 mm in width.Left eyes of these were followed up for control group. Spherical equivalent, corneal power, and axial length were measured before SB and at 2, 4, and 8 weeks postoperatively. We compared these measures between experimental and control groups, and analyzed the influence of age at operation. In control group, corneal refractive power was decreased, axial length was increased, and spherical equivalent developed emmetropization in aging. High myopia was developed in all eyes with SB, and the increase of axial length was the major factor in myopia.These changes were greater in group A than group B.In experimental group, the degree of myopia was increased at 4 and 8 weeks postoperatively, but corneal power and axial length were not statistically changed. In conclusion, the SB in younger rabbits induced higher degree of axial myopia.These findings may suggest that SB in infant could induce significant axial myopia and secondary amblyopia, especially younger age.

Hydrofluoric acid(HF) burn is characterized by progressive tissue necrosis and severe pain. A 31 year old employee in the semiconductor industry came in contact with the 50% aqueous HF through a pin hole in the thumb of his protective gloves. About 2 hours after exposure, h noted deep, severe burning, excruciating pain and svtelling of right thumb. Thereafter, clark bluish eclematous necrotic patches were visible through the nail plate and on the distal end of right thumb. Pain was not effectively relieved by digital nerve block.

Cervical tab is one of the congenital anomalies, originated from an accessory tragus or a remnant of branchial cartilage on the head a.nd neck. A 41 year old male patient was seen with 1.1 x0.8cm sized cartilage consistent intredermal nodule on the left supraclavicular area. Histopathologic findings showed the oval shaped cartilags surrounded with connective tissue and interstitial substance stained black with Verhoeff van Gieson stain.
