As a modality of effective treatment for trichiasis, authors performed experimental study of the radio frequency application(Mehl's method) to the cilia of four rabbit eyes with the different application times(10, 30, 60, 180 seconds). For the control, electrolysis to the cilia of the two eyes, and two eyes without any application were observed histopathologically. Regardless of the radio frequency application time, the radio frequency applied eyelids did not reveal any gross changes, and the selective degenerative changes(pyknotic, vacuolar, and karyorrhaxis) were observed microscopically in the hair regeneration part(internal root sheath of hair, hair matrix, and papillae of hair). In the electrolysed eyelids, gross scar and severe necrotic changes were appeared in microscopic findings. As a result of our observation, it is indicated that the application of radio frequency as a treatment for trichiasis, in compare with the electrolysis, revealed less destructive to the adjacent tissue, with more selective changes on the portion for hair regeneration.

PURPOSE: To evaluate the results between open reduction and internal fixation with the plate and percutaneous reduction by towel clip and intramedullary fixation with Steinmann pin for clavicle shaft fractures in adult. MATERIALS AND METHODS: We have studied the results in 33 cases with the plate, 35 cases with the Steinmann pin among total 68 cases of clavicle shaft fracture. The patients were followed up over a period of at least 12 months. The final postoperative outcome was analyzed with the clinical outcomes using Kang's criteria, radiological union time and operation time. RESULTS: The clinical outcome that was good or excellent according to the Kang's criteria showed a distribution of 88% in the group using the plate with 29 cases out of total 33 cases, 91% in the group using the Steinmann pin with 32 cases out of total 35 cases. The mean radiological union time was 8.9 weeks in the group using the plate, 9.1 weeks in the group using Steinmann pin. The mean operation time was 72 minutes in the group using the plate, whereas was 18 minutes in the group using Steinmann pin. CONCLUSION: In the treatment of adult clavicle shaft fracture, two groups did not show a significant statistical difference in clinical and radiological outcomes. However, the operation time and postoperative functional recovery was significantly shorter and faster in the group using Steinmann pin. Additionally economic and cosmetic aspect was more satisfactory in the group using Steinmann pin.

Isolated avulsion of the lesser tuberosity of the humerus is a rare injury. The mechanism of injury is the avulsion of the lesser tuberosity from forced contractions of the subscapularis muscle when the arm is forced into an externally rotated position on shoulder abduction. Authors report a case for isolated avulsion of the lesser tuberosity of the humerus which was treated with open reduction and transosseous suture fixation, as well as a view of the literature.

PURPOSE: The purpose of this study is to evaluate the radiographic and clinical results of patella fractures using a circumferential wiring combined with tension band wiring. MATERIALS AND METHODS: Between January 2005 and June 2012, 22 (male 14, female 8) patients with patella fracture treated with circumferential wiring combined with tension band wiring were analyzed retrospectively. The mean age of patients was 51 years (range, 28 to 72 years). Controlled passive range of motion exercise was started at three weeks from the postoperative day. The patients were evaluated using radiographs, clinical examination, and Levack's scoring system. RESULTS: All fractures healed and mean time elapsed for union was 11.5 weeks (range, 10 to 14 weeks). Complete union without displacement and full range of motion was achieved in all cases. Clinical results according to Levack's scoring system were excellent in 20 cases and good in two cases. We found broken wire in one case. In this case, results of clinical evaluation after reoperation were good. CONCLUSION: Circumferential wiring combined with tension band wiring is appropriate for patella fractures.

PURPOSE: To report the clinical results from surgical treatment for clavicle shaft fracture by percutaneous intramedullary fixation with Steinmann pins. MATERIALS AND METHODS: Between January 2004 and June 2014, the medical records of 135 patients who underwent percutaneous intramedullary fixation with Steinmann pins were reviewed. The mean follow-up periods were 15 months. The functional results were evaluated with The Disabilities of the Arm, Shoulder and Hand (DASH) score and Constant score. The clinical results were evaluated with the shortened length of the clavicle, length of surgical wound, operation time and Kang's criteria. RESULTS: The mean bone union period was 11.6 weeks (8–16 weeks). The mean DASH score was 11.8. The mean Constant score was 91.2. The mean shortened length of the clavicle was less than 20 mm. The mean length of surgical wound was 1.2 cm (0.7–1.5 cm). The mean operation time was 18 minutes (10–35 minutes). Using Kang's criteria, 131 out of 135 patients (97.0%) showed good results. Complications included were 3 pin migrations and 2 non-unions. CONCLUSION: Percutaneous intramedullary fixation with Steinmann pins showed good results for treating clavicle shaft fracture.

OBJECT: The goals of radiosurgery include preservation of neurological function and prevention of tumor growth. We document the results of gamma-knife radio-surgery for vestibular schwannoma. METHOD AND OBJECT: Eighty-two patients underwent stereotactic radiosurgery for an vestibular schwannoma from October, 1994 to December, 2000. Sixty-five of these patients were followed up for radiological and clinical evaluation. As pregamma-knife modality, surgical resection were done in 23 patients,and V-P shunt in 2 patients. Initial symptoms were headache(n=45), dizziness(n=16), tinnitus(n=17). While normal facial function(House-Brackmann grade 1) was present in 48 patients(73.8%), other patients showed grade 2 function in 8, grade 3 function in 7,and grade 4 function in 2. The Gardner/Robertson scale was used to code hearing function. Male to female ratio was 1:3. Mean tumor volume was 7.98cm3. Mean dose delivered to the tumor margin was 14.2Gy,and mean maximal dose was 28.3Gy. RESULTS: Mean follow-up duration of 19.9 months. Thirty-five showed decrease(53.8%) in size, 19 patients(29.2%) stationary, 3(4.6%) initial decrease follow up increase, 5(7.6%) initial increase follow up decrease,and 59 patients (90.8%) were well controlled. Two patients experienced transient facial neuropathy, one transient trigeminal neuropathy, and one transient hearing deterioration. After gamma-knife radiosurgery, ventriculoperitoneal shunt was done in 4 patients. CONCLUSIONS: Gamma-knife radiosurgery can be used to treat postoperative residual tumors as well as in patients with concomitant medical problems in patients with preserved hearing function. Gamma-knife radiosurgery is safe and effective method to treat small, medium sized(less than 3cm in extracanalicular diameter), intracanalicular vestibular schwannoma, associated with low rate of cranial neuropathy.

PURPOSE: To evaluate clinical and radiological results using 3.5 mm & 2.4 mm volar locking compression plate (LCP) in distal radius fractures. MATERIALS AND METHODS: This study reviewed the results of 115 cases of distal radius fractures treated with 3.5 mm volar LCP (73 cases) & 2.4 mm volar LCP (42 cases) from September 2003 to June 2009. The radiographic results were evaluated by radiographic assessment, and the clinical results were evaluated by Knirk and Jupiter's criteria, Modified Mayo wrist scoring system and DASH score. RESULTS: Radiological evaluation of the radial length, radial inclination, volar tilt and intraarticular step off were improved both 3.5 mm volar LCP and 2.4 mm volar LCP. Nine cases of arthritis occured in 3.5 mm volar LCP and 7 cases in 2.4 mm volar by using the Knirk and Jupiter's criteria. The mean score evaluated by Modified Mayo was 86.7 in 3.5 mm volar LCP and 84.8 in 2.4 mm volar LCP. DASH score was 11.2 point in 3.5 mm volar LCP, 10.9 point in 2.4 mm volar LCP. All cases showed bone union showing no evidence of malunion, nounion, nor metal failure. CONCLUSION: Distal radius fractures treated with 3.5 mm volar LCP and 2.4 mm volar LCP show satisfying radiological and clinical outcome.

Ganglioneuromas commonly arise from sympathetic ganglia. These neoplasm may be located wherever ganglion cells are normally found from skull base to pelvis including adrenal gland. Ganglioneuromas in spinal cord are very rare. We report a case of dumbbell-shaped extradural spinal ganglioneuroma. A 7-year-old boy was admitted to our hospital with a 20 day-history of both leg pain and a 10 day-history of progressive paraparesis. On magnetic resonance image, there was a dumbbell-shaped extradural spinal cord tumor in T11-L4 level. Two stage operation(First : Laminoplastic laminotomy of T11-L4 to remove the extradural portion of the tumor in the spinal canal, Second : Right retroperitoneal approach for the removal of paraspinal tumor located in L2-3 level) was performed. Pathologic diagnosis was a ganglioneuroma and paraparesis improved postoperatively.

PURPOSE: We evaluated the results of operative treatment with F or H plates and screws using extensile lateral approach in intraarticular calcaneal fractures. MATERIALS AND METHODS: From August 2003 to July 2006, twenty intraarticular calcaneal fractures which were operated with open reduction and internal fixation with F or H plates and screws were evaluated retrospectively. According to the Essex-Lopresti classification, 3 cases were tongue type and 16 were joint depression type. With the Sanders classification, 2 cases were II A type, 7 were II B, 5 were III AB, 2 were III AC and 3 were IV. We have analysed the Bohler angle, Gissane angle, and calcaneal width in radiologic evaluation, and evaluated clinical result according to the Creighton-Nebraska Health Foundation Score. RESULTS: Radiologic changes showed as follows: Bohler angle improved from 5.8 degrees to 25.9 degrees, Gissane angle from 119.0 degrees to 113.3 degrees, and calcaneal width from 50.4 mm to 37.8 mm. In the clinical results, excellent cases were noted in 8 cases, good in 8 cases, fair in 2 cases, poor in 1 case. CONCLUSION: Operative treatment with F or H plates and screws using extensile lateral approach in intraarticular calcaneal fractures was thought to be a useful operative method allowing anatomical reduction.

Journal of the Korean Fracture Society 2008;21(4):274-278
PURPOSE: To evaluate the clinical and radiographic results of treatment of trochanteric fracture with ITST (Intertrochanteric/ Subtrochanteric) nail. MATERIALS AND METHODS: We reviewed the results of 40 cases of trochanteric fracture treated with ITST from January 2006 to May 2007, which could be followed up for more than 12 months. The cases include 13 males and 27 females, and the mean age is 75.6 years old. The clinical results were evaluated by Ceder mobility assessment, and the radiographic results were evaluated by the change of femoral neck-shaft angle and sliding of lag screw. RESULTS: The mean bone union time is 13.5 weeks. Thirty four cases (85%) were recovered to pre-injury state of walking ability. The change of neck-shaft angle was an average of 5.21degrees and the sliding distance of lag screw was an average of 5.78 mm. Complications were occurred in 4 patients (10%). CONCLUSION: The ITST nail were seen good results in treatment of trochanteric fracture and has relatively less complications than other internal fixator.
