Purpose: To evaluate the results in patients who received total elbow replacement for posttraumatic destroyed or unreduced elbow joint. Materials and Methods: Six patients with posttraumatic destroyed, or unreduced elbow joint, who were nearly impossible to move actively and had pain and grossly unstable joint, were followed up average 42 months. 3 cases were soft tissue injuries and bone defects which were caused by severe comminuted fracture, 1 was a nonunion with comminuted fracture, and 2 were unreduced elbow joint. Total elbow replacement was performed average 10 months after the injury. All the cases were used by semiconstrained prosthesis, and the results were estimated by Mayo elbow perfomance score. Results: Pain was decreased in all the cases postoperatively. Average ranges of motion were improved with active extension 20° and flexion 120°. Mayo elbow performance scores were pain 42.5 points, range of motion 17.5 points, stability 8.3 points, function 19.2 points and totally 87.5 points, and final results were 3 excellent and 3 good. Loosening of prosthesis was not found in all the cases by final follow-up radiograph. Conclusicon: Semiconstrained TER can be used as a effective treatment improving pain and active ranges of motion caused by posttraumatic destroyed or unreduced elbow joint, however, long term follow-up is needed because early loosening of TER can be occurred due to severe bone defects.

Purpose: Limitation of motion of the elbow joint due to stiffness affect on life quality of the patients. So contracture of the elbow should be treated as soon as possible. Among the many treatment modalities, we described the result of arthroscopic treatment. Materials and Methods: From Mar. 2000 to Mar. 2003, 40 patients, who received the arthroscopic treatment by author for contracted elbow, were the subjects. We estimated the range of motion (ROM) of elbow joint before and after surgery by goniometer. The clinical result was evaluated by Severance elbow scoring system. The final ROM was evaluated at the point of no further increasement of joint motion. Male ware 30 cases, female ware 7 cases, average 42.6 years old and mean follow up period were 31 months. During arthroscopic treatment we had done release of the joint capsule or resection, synovectomy, removal of loose bodies. We used traditional portals. Results: The avarage preoperative ROM of elbow joint was 72.5 degree(range, 5 - 132 degree) and the increasement of ROM was totally 49.3 degree in flexion 26.5 degree and extension 22.8 degree. There was no other complication. Conclusion: Arthroscopic treatment for contracted elbow permit early joint ROM and it decrease the secondary injury to the elbow joint. Also there are few complications. It is thought to be a good treatment modality in contracted elbow joint.

Arthroscopy of the stiff elbow joint is a technically difficult procedure because of the decreased joint space of the elbow joint. even to experienced surgeons. Problems encountered include limited access of instrument to the intra-articular ,pace and an increased risk of cartilage injury in the contracted elbow joint. This study describes a novel transarticular approach for elbow arthroscopy that allow, the safe and effective creation of the proximal medial and lateral portals.

Objectives : We got a good effect in two patients not by subcutaneous but by subcutaneous but by intra-articular bee venom injection treatments at traumatic arthritis of elbow joint, so report it. Methods : We used only intra-articular bee venom injection treatments at acute traumatic arthritis of elbow joint. After measured the VAS(visual analogue) and ROM(range of motion) of elbow joint, we bee venom injection effect. Results and Conclusions : The symptoms(swelling, pain) and the functions of elbow joint were quickly improved through intra-articular bee venom injection treatments. One case was improved that Rt. elbow joint flexion was increased from $60^{\circ}$ to $150^{\circ}$, extension was increased from $20^{\circ}$ to $0^{\circ}$. The other case was improved that Lt. elbow joint flexion was increased from $90^{\circ}$ to $150^{\circ}$, extension was increased from $30^{\circ}$ to $0^{\circ}$, and both were decreased in VAS. The results suggest that bee venom intra-articular injection has acute pain reduction, anti-inflammation effect.

본 논문에서는 인간의 팔꿈치 관절의 기능을 활성화하기 위한 강성 기반 재활 메커니즘의 특성을 분석하 고자 한다.여기서,팔굼치 관절의 재활을 위한 도구는 탄성 줄을 사용하고, 사용된 줄은 선형 스프링으로 모델링하여 강성값으로 나타낸다. 이러한 메커니즘을 이용한 팔꿈치 관절 재활 훈련을 효과적으로 하기 위해서는 줄의 강성값에 따라 팔꿈치 관절에 가용할 수 있는 토오크 특성을 분석할 필요가 있다. 이러한 관점에서 다양한 시뮬레이션을 통하여 탄성 줄의 강성값 설정에 따른 팔꿈치 관절의 토오크 패턴 및 범위를 사전에 정의된 팔꿈치 관절의 운동 경로에 대하여 확인한다. 결과적으로, 이러한 강성 기반 재활 메커니즘이 팔꿈치 관절의 효과적인 재활을 수행하는데 유용하게 활용될 수 있음을 보인다.

Author report a case of double metatarso-phalangeal joint transplantation to the elbow joint in the 31 years old female patient who have large bone defect associated with skin and soft tissue defect. The donor joints were second and third metatarso-phalangeal joint as double joint transfer fashion to enhance stability of graft. The graft based on dorsalis pedis vessel to anastomosed with radial artery of recipient site. The result is unsatisfactory because of long lasting lateral instability of reconstructed elbow joint in spite of 40 degree flexion motion and fair axial stability. We can conclude that joints from foot can not be an effective donor for biologic joint arthroplasty of elbow joint even though double metatarso-phalangeal joint were harvested.

The purpose of this study was to identify the difference and correlation in elbow joint maximal flexion strength according to measurement methods and characteristics of muscular contraction, and to develop the predictive equation of elbow joint maximal flexion strength for the optimal exercise intensity setting and accurate measurement. Subjects were 30 male university students. Elbow joint maximal flexion strength of isokinetic contraction, isometric contraction at $75^{\circ}$ elbow joint flexion position, isotonic concentric 1RM, manual muscle strength (MMT) were measured with isokinetic dynamometer, dumbbell, and manual muscle tester. Pearson's r, linear regression equation, and multiple regression equation between variables were calculated. As a result, the highest value was isometric contraction. The second highest value was MMT. The third highest value was isokinetic contraction. 1RM was the lowest. Predictive equations of elbow joint maximal flexion strength between isometric and isokinetic contraction, between isometric contraction and 1RM, among isometric contraction, 1RM, and body weight were developed. In conclusion, 1RM and isokinetic elbow joint maximal flexion strength could be seemed to underestimate the practical elbow joint maximal flexion strength. And it is suggested that the developed predictive equations in this study should be useful in criteria- and goal-setting for resistant exercise and sports rehabilitation after elbow joint injury.

Objectives : We find that the reaction force on the elbow joint during elbow flexion, extension with and without an object in the hand can be calculated the equations of motion that the sum of the torque and the sum of the force acting on the elbow joint must be zero and (moment of inertia x angular acceleration) and (mass x acceleration). Methods : we have calculated the equations of motion (${\Sigma}F=0$, ${\Sigma}{\tau}=0$, ${\Sigma}F=ma$, ${\Sigma}{\tau}=Ia$) to investigate the reaction force on the elbow joint during elbow flexion, extension by means of the simplified free-body technique for coplanar forces. Results : we found that the reaction force on the elbow joint during elbow flexion, extention as constant acceleration motion is more than constant velocity, static motion. Also, we found that the relation between during flexion and during extension like this ; $J_{flexion}$ < $J_{extension}$.

A relation between the movement range of arms and arising moment has been studied to find out efficient movement range to minimize impact concerning arm landing in sports aerobics. Four male athletes who won top three in national-level sports aerobics competition were chosen for the experiment. They were allowed to jump in between two force platform so that the right hand and the right leg could land onto the front and rear force platform, respectively. The sampling frequency was 200 Hz. The main conclusions based on the analysis of the angle and joint moment parameters of wrist, elbow, and shoulder are as follows: 1. The wrist moment was small when its angle was small, indicating that the dorsi-flexion of the wrist joint offered a positive influence to reduce wrist moment. 2. The elbow angle increased as wrist angle decreased and vice versa. This means that the movement range of the wrist joint affects that of the elbow joint. The darsi-flexion of the wrist is the position to absorb the impact of the elbow effectively rather than to absorb the impact of the wrist itself. The impact is absorbed by the flexion of wrist joint rather than the wrist. 3. The degree of moment transfer of the shoulder joint, having absorbed the impact from the elbow and elbow joint, became dependent on the efficiency of the fore-joints impact absorption.
