Purpose: It is not always easy to determine the existence of tendon injuries when it comes to patients with finger lacerations. Thus, we tried to find the difference in effectiveness and in compliance of patients when we employed two different types of diagnosis, conventional gross confirmation and ultrasonographic confirmation. Methods: From December 2009 to March 2010, we enrolled 14 patients with finger tendon injury at Soonchunhyang University Cheonan Hospital. The median age of the patients was $35.9{\pm}14.4$, and the ratio of females to males was 1:2.5 We evaluated the compliance of each patient by measuring four different categories (level of cooperativeness in showing their wound and in following the instructions, level of movement of their fingers during the diagnosis and total number of attempts to diagnose) by using a score from 1 to 3 for each category, for a total possible score of 12 for each patient. We also measured the painfulness of each patient by using a score of 1 to 10 and the time required for each diagnosis. Results: The levels of patients' compliance was $8.9{\pm}2.1$ when diagnosed with gross confirmation and $9.8{\pm}2.1$ when diagnosed with ultrasonographic confirmation (p value=0.042). The pain score of the patients was $3.7{\pm}1.7$ with gross confirmation and $2.9{\pm}1.2$ with ultrasonographic confirmation (p value=0.020). The median duration of time in each test was $6.7{\pm}4.8$ minutes with gross confirmation and $10.5{\pm}4.2$ minutes with ultrasonography (p value=0.006). Conclusion: Comparing gross confirmation and ultrasonographic confirmation, gross confirmation is a better method than ultrasonography because of time efficiency. However, ultrasonographic confirmation has advantages over gross confirmation in pain scale and better compliance of patients. Emergency physicians generally employ gross confirmation rather than ultrasonography in determining the existence of tendon injury in patients. In patients with finger lacerations without bone injury, ultrasonography can be considered as a secondary diagnostic tool, especially when patients have much pain.

Purpose: Arthroscopic repair of rotator cuff tears are many techniques that have been developed to improve the initial postoperative strength of the repair. There was a doubt that current arthroscopic cuff repairs using a single row of suture anchors reproduce insufficient area of the anatomic cuff insertion, and concerns about failure of fixation often lead surgeons to limit early motion. Newer technique of double-row repair in arthroscopic treatment may provide initial stronger fixation and more contact with bone at the repair site than single-row repair did. We studied the comparison between clinical outcomes of arthroscopic single- and double-row repair in cuff tears at 1year postoperatively. Materials and methods: We retrospectively analyzed 40 shoulders with single-row repair and 38 shoulders with double-row repair of full-thickness rotator cuff tears between May 2002 and October 2004. Out of total 78 shoulders, 42 (54%) were male patients and 36 (46%) were female patients and the mean age at surgery was 56 years. All patients were diagnosed by physical examination and MRI. At 1year' follow-up after operation, we evaluated with the ASES and the Constant scoring system, and measured muscle power of abduction, internal and external rotation of the affected shoulder then compared with each other. Results: Mean ASES scores and Constant scores in double-row repair group improved more than single-row repair group significantly at 1year postoperatively. Muscle power of abduction and internal rotation, especially abduction power, improved more significantly in double-row repair group than in single-row repair. Conclusion: Arthroscopic double-row repair for the full thickness rotator cuff tear may be a superior technique, which showed better clinical outcomes and restoration of muscle power compared with single-row repair at relatively short period of postoperative follow-up. Restoration of footprint close to normal anatomy by double-row repair seems to play an important role in the recovery of muscle strength.

Purpose: To evaluate and compare the results of children with displaced supracondylar fractures of humerus treated with open reduction and pinning with closed reduction and pinning. Materials and Methods: From March 2002, we treated 17 patients with completely displaced supracondylar fractures under the age of 7 with a minimal follow up period of 6 months. 9 patients were treated with closed reduction and pinning and 8 patients were treated with open reduction and pinning. The clinical results were evaluated with Flynn's criteria. Time to bone union was also analyzed for these two set of patients. Results: The group treated with open reduction had 6 excellent and 2 good results for change in carrying angles, 5 excellent, 2 good and 1 fair results for motion loss evaluated by Flynn's criteria. The average time to bony union for this group was 5.8 weeks. The group treated with closed reduction had 6 excellent, 2 good, and 1 fair results for change in carrying angles and 7 excellent, 1 good and 1 fair results for motion loss. The average time to bony uinon for this group was 3.7 weeks. Conclusion: In treating completely displaced supracondylar fractures of humerus in children, the closed reduction method and open reduction method all showed good results. But the operation time, duration of hospital stay and time to union was somewhat shorter for the patients treated with closed redution and pinning.

Purpose: Despite the free tissue transfer using microsurgical technique being the current trend of soft tissue reconstruction of the hand, the pedicled groin flap has the advantage to provide coverage for the mangled hand without necessitating the use of a damaged arterial system and also providing the benefit of saving the arterial system for later free tissue transfer. This report presents the author's experience using pedicled groin flap in four cases of mangled hands with massive bone and soft tissue defects requiring later thumb reconstruction with the free wrap around flap. Materials and methods: The patients' age ranged from 30 to 51 years; three patients were male and one was female. The causes of mangled hand included two machinery crush injuries, one laboratory explosion and one motor vehicle accident. While evaluating the post-operative results, factors like flap survival, complications, stability in opposition, pinch power and 2 point discrimination were taken into account. Results: All massive soft tissue defects of the hands were completely covered with pedicled groin flap successfully. The reconstructed thumb using free wrap around flap did not have any limitation in opposition. There was no occurrence of post-operative infection and all the flaps survived completely. The average pinch power was 70% of the contralateral intact thumb and average 2 point discrimination was 10 mm. Conclusion: The pedicled groin flap for the reconstruction of the massive soft tissue defects of the hand with subsequent reconstruction of the thumb with a wrap around flap is a very useful procedure. The combined use of pedicled groin flap and wrap around flap allows adequate coverage of sizable soft tissue defects and functional thumb opposition in cases of reconstruction of the mangled hands.

치아의 맹출은 일반적으로 치근의 1/2~2/3이 완성(Nolla stage 7)되었을 때 임상적으로 출은(emergence)하여 치근 형성이 완성되기 전에 교합평면에 도달한다. 조기 맹출이란 맹출이 가속화되어 정상 맹출 시기 보다 이른 시기에 맹출하는 것으로, 일반적으로 정상 범주를 벗어나는 영구치의 조기 맹출은 매우 드물며 유치의 만성 치근단 주위염 등의 국소적 원인으로 인한 계승 영구치의 상방 치조골이 광범위하게 파괴되었을 때 치아의 치관이나 치근의 형성이 거의 이루어지지 않은 채 계승 영구치가 조기 맹출하는 것을 관찰할 수 있다. 또한 영구치의 조기 맹출에 영향을 미칠 수 있는 여러 전신 질환이 있는 경우에도 영구치의 조기 맹출이 가능하다. 조기맹출 치아의 임상 소견으로는 심한 동요도와 저작 시 동통, 법랑질의 저석회화, 치아의 편향과 변위, 회전 등이 있으며, 방사선학적 소견으로는 미발육된 치근과 골지지의 부족 등이 있다. 조기 맹출 영구치의 발생 가능한 합병증으로는 만성적인 외상과 동통 및 부종이 있을 수 있고, 맹출 순서의 변경과 인접치의 이동으로 인한 소구치 매복율의 증가, 치아의 변위와 회전이 야기될 수 있으며, 영구치의 탈락도 있을 수 있다. 따라서 증상이 있는 조기 맹출 영구치의 경우 공간 유지 및 영구치 고정과 주위 조직의 회복, 치근 발육의 유도를 위해 적절한 처치가 필요하다. 전신 질환이 없는 만7세 여환이 상악 양쪽 제 1소구치의 심한 동요도와 동통을 주소로 치과 의원에서 의뢰되었다. 임상 및 방사선 검사상 치근 형성이 거의 없이 양측 상악 제 1소구치들이 조기 맹출되어 심한 동요도와 부종 및 저작 시동통을 나타내어 상악 제 2유구치에 교정용 band와 spur를 이용한 구내 고정식 장치를 제작하여 14개월 간 장착하여 조기 맹출한 치아들을 안정화시키고 성공적으로 치근 형성을 도모하였기에 이를 보고하는 바이다.

상악 중절치는 저작시 음식물을 찢거나 자르는 기능 외에도 심미적으로 중요한 기능을 하며 상악 악궁의 형태 및 얼굴의 형태와도 관계가 있다고 알려져 있다. 그리고 발음을 하는데 있어서도 전치부는 매우 중요한 역할을 한다. 예후가 불량한 치아의 일반적인 치료는 발거 후 공간 유지장치를 하는 것이다. 그러나 혼합치열기에 있어 상악 영구 중절치의 발거는 치조골의 흡수, 불량한 심미성, 발음과 저작의 문제 등 여러 가지 합병증을 일으킬 수 있다. 이러한 이유로 상악 전치부의 치료는 보존적으로 행해져야 한다. 예후가 불량한 상악 전치부의 치료시 고려해야 할 사항으로는 환아의 나이, 성장 잠재력, 교합 관계, 구강 위생상태, 경제력 그리고 환아의 치료에 대한 협조도 등이 있다. 본 증례는 짧은 치근으로 인해 치아의 동요도가 있어 상악 좌측 중절치의 예후가 불안정함에도 불구하고 치아를 발거하지 않고 치료를 통해 상악 좌측 중절치를 정상 위치로 배열하고 보존하였다. 짧은 치근과 치아 회전으로 인한 추가적인 치근 흡수와 치아 동요도 증가 등 예후가 불안정하였지만 환아의 심리적 안정성, 나이, 심미성 등을 고려하여 보존적인 치료 후 양호한 결과를 얻었기에 이를 보고하는 바이다.

Elderly people comprise an increasing proportion of the population, and nutritional impairments may contribute to health problems among this group. This study was conducted to evaluate the nutritional status by Mini-Nutritional Assessment (MNA) and to identify relationships among anthropometric measurements, biochemical indicators, bone Mineral Density (BMD) and MNA results among older adults (${\geq}$65 yrs, n=98, 66.7${\pm}$2.5 yrs; M=52, F=46, BMI 24.5${\pm}$2.8 $kg/m^2$) at a Health Care Center. A dietitian administered MNA and collected anthropometric measurements (weight, height, waist circumference), biochemical indicators (albumin, hemoglobin, hematocrit, TLC, glucose, lipids) and the BMD (spine, femur, F=46). Subjects were grouped into a normal nutrition group (0~2 risk factors of malnutrition) and a high risk of malnutrition group (>=3 risk factors of malnutrition) based on their risk factor status for malnutrition. The risk factors for malnutrition include age ${\geq}$65 years, PIBW <90%, albumin <3.5 g/dl, TLC <1,500%, Hgb <14 g/dl (men), Hgb <10 g/dl (women), loss of appetite and weight loss 1~3 kg/last 3 months. In addition, subjects were grouped into a normal, osteopenia and osteoporosis group by BMD. We found that 12% of the subjects were at risk of malnutrition (MNA score, 21.4${\pm}$2.1) and that 88% were well nourished (27.3${\pm}$1.5) according to the MNA. Full-MNA scores were positively and significantly (p<0.05) associated with BMI, mid-arm circumference (MAC), calf circumference (CC), albumin and hemoglobin, respectively. The full-MNA score of the high risk of malnutrition group (23.0${\pm}$3.8) was lower than that of the normal nutrition group (27.0${\pm}$2.1) (p<0.05). In addition, the Full-MNA score was negatively associated with the risk factor of malnutrition (r=－0.35, p=0.0004). We found that 39.1% of the subjects had osteoporosis, 45.7% had osteopenia and 15.2% were normal according to their BMD. The MNA score of osteoporosis group (24.58${\pm}$3.3) was lower than that of the normal (27.4${\pm}$1.1) and osteopenia group (26.9${\pm}$1.5) (p<0.05). These results suggested that MNA can be useful as a nutritional screening tool of older adults in Health Care Centers.
