Purpose: to determine the results after open intramedullary nailing and tension band suture technique in proximal humerus fracture for improving the stability and decreasing the complications. Materials and Method: Authors reviewed 27 patients treated by open intramedullary nailing and tension band suture technique. Mean follow-up period was 39 months (24-59months). Surgical neck fracture were 6 cases, surgical neck fracture with shaft fracture were 3 cases, three part fracture with greater tuberosity fracture were 17 cases, four part fracture was 1 case and fracture and dislocation were 2 cases Results: We got the bony union in 26 cases. Average pain scale was 1 point (0-6), Neer score was 86 point(45-99) and ASES score was 85 point(40-100). We separate all cases in two groups based on age (65 years), L-spine t-score (-2.5) and Neer classification (2 and 3 part). There is no significance in pain scale, Neer score and ASES score between each group. Conclusion: As a method of surgical treatment on severe proximal humeral fractures, we recommend intramedullary nailing and tension band suture technique and it may have particular advantages in early exercise and satisfactory functional outcome.

목적: 압박 긴장대 방법을 이용한 작은 구상 돌기 골절의 견고한 고정과 주관절의 조기 운동을 통한 기능의 향상 및 그 결과를 분석하고자 한다. 재료 및 방법: 주관절 내측접근법으로 K-강선과 철선을 이용하여 고정된 8예의 구상돌기 골절을 대상으로 하였다. 분류상 8예 모두 Regan-Morrey type 2였으며 O'Driscoll 분류12)로는 tip형(subtype 2)가 예, anteromedial 형 (subtype 2, 1예 그리고 subtype 3, 2예)3예였다. 동반 손상으로는 측부인대 파열이 6예, 요골두 및 경부골절이 4예였으며 모두 함께 치료하였다. 술 후 5~7일간의 고정 치료 후 경첩 보조기 (hinge brace)을 착용한 상태에서 술후 6주까지 능동적 운동을 허용하였다. 술 후 통증의 여부, 관절 운동 범위, Mayo elbow performance score(MEPS)을 이용한 기능적 평가 방법을 이용하여 치료 결과를 분석하였다. 평균 11 (6~28)개월 추시 하였으며 척골 신경 증상에 대해서도 함께 조사하였다. 결과: 모든 구상돌기 골절은 내고정용 도구의 실패 없이 모두 유합되었다. 평균 2.2 (2~4)개의 K-강선이 사용되었다. 관절운동 범위에 대해 신전은 평균 $3^{\circ}(0^{\circ}\sim25^{\circ})$, 굴곡는 평균 $137^{\circ}(130^{\circ}\sim140^{\circ})$, 회내전은 평균 $69^{\circ}(45^{\circ}\sim90^{\circ})$, 회외전은 $78^{\circ}(45^{\circ}\sim90^{\circ})$이였다. MEPS는 평균 96 (65~100) 이였다. 척골 신경 증상은 terrible triad 1예에서 첫 수술 (index operation)후 요골두를 절제하고 내측 측부 인대의 기능 부전이 있는 1예에서 관찰되었다. 결론: 쉽게 구할 수 있으며 가격이 저렴한 K-강선과 철선을 이용한 압박 긴장대 방법은 충분히 견고하여 조기에 능동적 운동을 허용할 수 있어 주관절의 기능 향상을 가져올 수 있었다. 이 방법은 특히 다발성 소형 구상 돌기 골절의 경우 유용한 하나의 고정 방법으로 생각된다.

This study compared the biomechanical properties of bone-stapling techniques with those of other fixation methods used for stabilizing tibial tuberosity fractures using 3-dimensionally (3D)-printed canine bone models. Twenty-eight 3D-printed bone models made from computed tomography scan files were used. Tibial tuberosity fractures were simulated using osteotomy. All samples were divided into 4 groups. Group 1 was stabilized with a pin and tension-band wire; group 2, with a pin and an 8 mm-wide bone staple; group 3, with 2 horizontally aligned pins and an 8 mm-wide bone staple; and group 4 with a 10 mm-wide bone staple. Tensile force was applied with vertical distraction until failure occurred. The load and displacement were recorded during the tests. The groups were compared based on the load required to cause displacements of 1, 2, and 3 mm. The maximum failure loads and modes were recorded. The loads at all displacements in group 4 were greater than those in groups 1, 2, and 3. The loads at 1, 2, and 3 mm displacements were similar in groups 1 and 3. There was no significant difference between groups 1 and 3. Groups 1 and 4 provided greater maximum failure loads than groups 2 and 3. Failure occurred because of tearing of the nylon rope, tibial fracture, wire breakage, pin bending, and fracture around the bone staple insertion. In conclusion, these results demonstrate that the bone-stapling technique is an acceptable alternative to tension-band wire fixation for the stabilization of tibial tuberosity fractures in canine bone models.

The purposes of this study were to analyze the muscle activities and the characteristics of muscle recruting patterns of lower limb for crouching start technique using four elite splint. The EMG technique was used to record muscle activities of both right and left sides of retus femoris, vastus medialis, biceps femoris, and gastrocnemius. Eight surface electrodes were placed on the surface of the selected muscles and one ground electrode was also attached on the back of neck(C7). One video camera was also used to record the crouching start motion to define 6 events and 5 phases for further analysis. The raw EMG data were filtered with band pass filter(10-350) to remove artifacts and then low pass filtered(4Hz) to find the linear envelope which resemble muscle tension curve. This filter EMG data were normalized to MVIC for the purpose of comparison between right and left sides muscle. The results of this study were as follows. All four subjects showed that vastus medialis muscle activity was comparatively higher than those of retus femoris, biceps femoris, gastrocnemius. And left side of muscle activity was comparatively higher than right side of muscle activity. Therefore, when the subjects starting out crouching start position, we recognized that the muscle of lower limb showed interaction effect by each muscle.

We report here on a case of Achilles tendon rupture associated with ipsilateral bimalleolar fracture that was caused by ski injury. The association of an ankle fracture with rupture of the Achilles tendon is even more infrequent, although both injuries alone are extremely common. We treated as a operation of Achilles tendon repair with Krackow method and open reduction with Tension-band wiring technique for bimalleolar fracture.

The purposes of this study were to analyze the muscle activities and the characteristics of muscle recruiting patterns of upper trunk for Ssirum dutguri technique using three top-ranked elite Ssirum players. The EMG technique was used to record muscle activities of both right and left sides of latissimus dorsi, biceps brachii, and erector spinae. Six surface electrodes were placed on the surface of the selected muscles and one ground electrode was also attached on the back of neck(C7). One video camera was also used to record the Ssirum motion to define 4 events and 3 phases for further analysis. The raw EMG data were filtered with band pass filter (50-400 Hz) to remove artifacts and then low pass filtered (4 Hz) to find the linear envelope which resemble muscle tension curve. This filtered EMG data were normalized to MVIC for the purpose of comparion between the subjects. The results were indicated that each subject with different physical characteristics showed very different muscle activity patterns. Although Ssirum dutguri is considered as foot technique the player grasped opponent's satba(belt) with both hands when they play. Because of this reason, activities of upper trunk muscles were relatively high. However, direct comparison between upper and lower body muscles was not possible due to the lack of the data in present study. Interestingly, all threes subjects showed that erector spinae muscle activity was comparatively higher than those of latissimus dorsi and biceps brachii. This implies to reinforce back muscle as a routine of training to improve performance or to prevent back injury.

The purpose of this study was to examine the effects of Task-oriented training on the balance, lapse time and MVC(Maximum Voluntary Contraction) of CVA(cerebral vascular accident) patients. The active balance equipment was used to measure of the static balance, lapse time and task-oriented training. The EMG technique was used to record muscle activitie of affected side of gluteus medius and vastus medialis. The raw EMG data were filtered with band pass filter (60Hz) to remove artifacts and then low pass filtered (20Hz) to find the linear envelope which resemble muscle tension curve. The experiment had been conducted at the department of physical therapy in J hospital in M city during 8weeks. The thirty patients experienced the stroke were participated: training group (15), control group (15). They were ambulatory with or without an assistive device. They were assessed on central perturbation(mm) in the static balance, lapse time(s) and MVC test(mV). The data were analyzed using repeated measured ANOVA. The results were as follows: After Task-oriented training, central perturbation and lapse time was significantly differences in both groups(p<.001), and MVC in gluteus medius were no significant differences in both groups, but vastus medialis was significant differences in both groups (p<.001).
