  • The management of acute acromioclavicular dislocations has usually followed the accepted principles of obtaining an anatomical reduction of the joint and maintaining it until soft tissue healing has occurred. So, the preferred treatment for acute acromioclavicular dislocation is controversial. We analysed operatively treated twenty-eight cases for acute acromioclavicular dislocation between February 1994 and January 1997 and reviewed postoperatively to evaluate the results of three different methods. We collected retrospectively the data via clinical history, associated injury, type of injury, radiographic review, Taft score, and final results. Follow up time averaged 14 months. (range, 12 to 21 ) In according to Rockwood's classification, ]7 cases were type Ⅲ, 1 case was type IV, and 10 cases were type V. Ten cases were treated with the modified Phemister method, ten cases with the modified Bosworth method and eight cases with the modified Weaver-Dunn method. ]n patients treated by modified Phemister method, the Taft score was 9.4 points and 8 cases achieved good or excellent results. In patients treated by modified Bosworth method, the Taft score was 9.8 points and 8 cases achieved good or excellent results. In patients treated by modified Weaver-Dunn method, the Taft score was 10.3 points and 7 cases achieved good or excellent results. The overall Taft score was 9.9 points and 23 cases achieved good or excellent results. There were four complications, such as calcification or metallic loosening or breakage of K-wire, but did not influence late results. In conclusions, there was no significant difference of results regarding the different three methods. However, our results indicated that the coracoclavicular ligament reconstruction by transfer of coracoacromial ligament produced better results.

  • Purpose: Despite of the popular use of the reconstruction plate for the fixation of clavicular shaft fractures, some disadventages have been raised such as long period of immobilization, long skin incision, loosening of plate and screws, and increased chance of nonunion due to severe periosteal injury. Thus, the authors have performed intramedullary multiple Steinmann pins fixation that could reduce the disadvantages of plate fixation in order to compare the treatment results between the two groups. Materials & Methods: From 1994. Jan. to 1997. Dec. the department of orthopaedic surgery of the Kwak's hospital treated operatively for 56 cases of the clavicular shaft fractures in adult. 39 cases of them were treated with the plate fixation and 17 cases with the intramedullary multiple Steinmann pins fixation(SP group). Reconstruction plates(Plate group) were used for 26 out of 39 patients treated with plate fixation. Among the Plate group and SP group, each 15 cases were selected by age and sex and compared each other according to the bone union time, union rate, complication, and functional results. The follow-up period was 12 months at the shortest and 48 months at the longest and the average was 16 months. Results: The Plate group showed that the bone union time was 7 weeks and the bone union rate was 93%. The SP group showed 6.5 weeks and 100% respectively. In complication, the Plate group had 1 case of loosening of plate and screws and delayed union; SP group had 1 case of pin migration. The functional results according to Kang's criteria, 87% of the Plate group and 93% of the SP group showed good or excellent. Conclusion : The SP group showed very comparable results in terms of the bone union time, bone union rate, complication, and functional results comparing to the Plate group. The intramedullary multiple Steinmann pins fixation showed several advantages over the reconstruction plate fixation, which were simple operative technique, easy removal of pins, being able to perform immediate postoperative full range of motion exercise. Therefore, the intramedullary multiple Steinmann pins fixation is thought to be one of the useful operative techniques in treatment of the clavicular shaft fractures in adult.

  • Purpose: We wanted to evaluate the results of surgical treatment for fracture of the scapular body. Materials and methods: The subjects of this study were seven patients with fracture of the scapular body and all these patients were managed surgically. We considered the operative indications as being 100% translation of the lateral border, or $25^{\circ}$ of angular deformity of the glenoid, or 1cm medialization or the variant of the double disruption of the superior scapular suspensory complex. There were five males and two females, and their ages ranged between 40 and 58 years (mean age: 49) with average follow up of 11 months (6~24 months). Two patients sustained multiple fractures of the ribs and spines. The surgical results were evaluated according to the subjective satisfaction, the UCLA score and the Korean shoulder score. Results: The mean UCLA score was 29 (17~33) and the mean Korean shoulder score was 86 (63~94). The self assessment for subjective satisfaction was 7.7 (4~9). There were two complications; one case of screw pull-out without the loss of the fracture fixation and the other case with screw penetration of the glenoid cavity. Conclusion: Surgical treatment may be effective for the management of severely displaced fracture of the scapular body in order to prevent the impairment of the shoulder function caused by the altered glenohumeral and scapulothoracic kinematics.

  • Purpose: The proper surgical methods for treating acromioclavicular joint dislocation is still controversial. New methods should provide better early motion with sufficient strength. Materials and Methods: We performed arthroscopic stabilization using TightRope$^{(R)}$ (Arthrex, Inc, Naples, FL) in 10 cases of acromioclavicular joint dislocation between April, 2007, and December, 2007, and followup for a minimum of 10 months. We performed radiologic evaluation by comparing the clavicle anteroposterior radiograph with the contralateral one. Clinical evaluation was made for pain, function, and range of joint motion by Imatani's methods. Results: In clinical evaluation, 6 cases were excellent, 3 cases were good, and 1 case was poor. In radiologic evaluation, 9 cases were excellent and 1 case was poor. Redislocation occurred in 1 case. Conclusion: During short-term followup, 9 of 10 patients who underwent arthroscopic stabilization using TightRope$^{(R)}$ had excellent results in Imatini tests and radiologic evaluation, except 1 patient with redislocation.

  • Naturally beared larvae obtained from female fish kept in the aquarium were reared for 45 days in the laboratory. The naturally beared larvae were 3.19 mm in average total length (TL) with 9+15~16=24~25 myomeres. Melanophores were distributed on the dorsal margin of intestine tube, ventral margins of the tail and around the oil globule, but none on the top of head and on the pectoral fins. The larva (3.35 mm TL) consumed all yolk and oil globule in 5 days after bearing, and jaw bones and clavicle began to be ossified rapidly. In 22 days after bearing, the larvae averaged 6.30 mm TL and the caudal notochord flex $45^{\circ}C$. Fin development in S. marmoratus larvae proceeds in the following sequence : caudal, pectoral, dorsal, anal and ventral fin.

  • Purpose: Here we report clinical results for surgical treatment of 2 cases of pyogenic arthritis and 1 case of tubercular arthritis, which only rarely develops in the sternoclavicular joint. Materials and Methods: From September 2003 to September 2008, we did early marginal resection and thorough debridement of osteomyelitis of the sternum and distal clavicle in 3 patients and evaluated clinical results after short-term follow up. Results: All 3 patients were satisfied with their clinical results and none had any recurrences according to follow up X-rays and laboratory datas. The follow up MRI showed bone edema in the distal clavicle and proximal sternum and a little fluid retention around the sternoclavicular joint. Conclusion: Even though diagnosis of these diseases are made earlier, infection of the adjacent bone and osteomyelitis could already have developed. We did early marginal resection and thorough debridement of osteomyelitis of the sternum and distal clavicle and achieved satisfactory results.

  • 1.목적 두경부암(head and neck Ca)과 쇄골상부(Supraclavicular)에 6MV 광자선으로 치료 시 치료부위(Target volume)가 피부에서 대략 $1^{\sim}2mm$정도 깊이에 위치할 경우, 6MV 광자선의 선량분포는 표면선량이 낮아서 치료에 적합하지 않기 때문에 Bolus와 같이 사용하지만 Skin Sparing(피부보호)효과의 손실로 피부의 손상이 발생할 수 있다. 이러한 이유로 피부의 보호와 치료 시 표면선량의 증가를 위해 Spoiler(산란판)를 제작하여 측정 후 그 특성을 이해하고 선량의 분포를 통하여 Bolus와 비교한 후에 Spoiler의 유용성에 대해 평가하고자 하였다. 2.방법 Siemens사 선형가속기(PRIMUS)의 6MV 광자선을 사용하여 Spoiler의 사용여부 및 Spoiler의 사용 시에는 조사면의 크기를 $5{\times}5,\;7{\times}7,\;10{\times}10,\;15{\times}15,\;20{\times}20cm^2$로 하고 Spoiler와 표면과의 거리는 6, 10, 15cm로 바꾸어 가면서 물팬톰(PTW. 독일)을 이용해 깊이와 측방에 따른 선량분포를 Markus 전리함(PTW. 독일)으로 측정하였으며 전리함의 방수를 위해 씌어진 방수 캡 때문에 표면선량을 별도의 고형 팬톰으로 측정하였다. 표면의 측정선량은 전리함의 측면 벽 등에 의한 선량 측정치의 증가 현상으로 과 반응을 보였으며 이를 교정하였다. 그리고 측정된 데이터를 치료계획 시스템(Pinnacle 6.0m)으로 비교, 분석하였다. 3.결과 Spoiler의 사용 시 3cm깊이 측정선량 백분율과 Spoiler를 사용하지 않은 해당 치료 조사면의 3cm깊이 선량의 백분율에 일치하도록 하여 가상의 치료 깊이인 2mm에서 측정값을 비교하여 본 결과 조사면 $5{\times}5,\;10{\times}10,\;20{\times}20cm^2$에서 OPEN시 62, 64, $70\%$, Bolus는 97, 97, $99\%$로 Spoiler의 사용 시 표면과의 거리가 6cm에서 82, 98, $103\%$, 10cm에는 72, 89, $101\%$, 15m에 65, 79, $96\%$로 나타났으며 표면에서의 측정값을 비교하여 본 결과 OPEN시 11, 17, $27\%$, Bolus는 84, 84, $86\%$, Spoiler의 사용 시 6cm에서 40, 71, $93\%$, 10cm에는 25, 50, $81\%$, 15cm에 18, 36, $67\%$를 나타내었다. 또한 3m깊이에서의 측방 선량분포에서 Spoiler의 거리변화(6, 10cm)는 심부선량의 변화에 영향을 주지 않는 것으로 확인할 수 있었다. 그리고 위의 실험측정치를 치료계획 시스템에 입력하여 선량분포를 확인한 결과 Spoiler를 사용하는 경우 OPEN에 비해 선량분포 영역을 표면으로 끌어 올릴 수 있으며 Bolus 보다 피부 보호효과는 어느 정도 유지가 되는 것을 보여주었다. 4.결론 이와 같이 Spoiler는 Bolus와 비교하여 6MV 광자선의 build up 영역을 표면으로 증가시키는 동시에 Skin Sparing(피부보호)효과를 유지할 수 있으며 두경부암의 치료에서 Spoiler의 사용이 가능한 조건으로는 조사면이 $5{\times}5cm^2$에서 Spoiler와 표면과의 거리가 6cm일 때, $7{\times}7cm^2$에서 6cm, 10cm였고 $10{\times}10cm^2$는 10cm, 15cm로, $15{\times}15cm^2$는 15cm의 간격으로 평가되었다. 또한 $20{\times}20cm^2$의 조사면, Spoiler가 6cm 간격 인 경우 Bolus를 사용한 것 보다 더욱 높은 표면선량을 나타내었다. 그러나 Spoiler와 표면간의 거리를 다르게 함으로써 깊이에 따라 선량분포를 다양하게 나타낼 수 있기 때문에 표면선량의 증가와 피부의 보호를 위해 환자의 피부 두께, 실제 치료 부위의 깊이 등을 고려한다면 Spoiler를 사용하는 것이 bolus를 사용하는 것보다 더 유용하게 적용할 수 있을 것으로 사료된다.

  • Skeletal development in the oblong rockfish, Sebastes oblongus, was studied based on extensive larval rearing conditions from December 2007 to March 2008. Newly-hatched larvae lacked osteological elements. After 3 days of bearing, jaw bones were ossified almost simultaneously with the frontal, parietal, clavicle, opercle, preopercle and branchiostegal rays at 8.0 mm average total length (TL). Ossification of the opercular was completed by 12.3 mm and the full complement of ossified elements of cranium and pectoral girdle were completed by 16.2 mm. Ossification of the cartilaginous caudal complex began to at 9.8 mm, and completely ossified by 18.0 mm. The fusing of the first and second, and the third and fourth hypurals initially occurred by 10.8 mm, and their fusion was finally completed at 18.0 mm. Notochord flexion occurred and formed an individual centrum by 8.5 mm and 10.8 mm, respectively, and all 26 centra were ossified by 13.2 mm. The preorbital bone began to ossify on the anterior region of eye at 10.8 mm, and the $1^{st}$ suborbital bone appeared ossified on the lower of eye by 12.3 mm, and all elements were ossified at 27.5 mm. Finally, after 71 days of bearing, the juveniles became 27.5 mm, and ossification was completed at this stage.
