1931년 Burman은 주관절의 제한된 관절 공간, 관절낭 팽창의 어려움, 삽입구 주변에 근접한 신경-혈관 구조물에 의해 주관절 관절경은 불가능하다고 보고하였다. 비록 1935년 자신이 다시 여러 번 시도 끝에 주관절 전방 관절낭을 관절경으로 관찰한 후 주관절도 관절경적 접근이 가능하다는 점을 처음으로 언급하였지만 1980년대 중반까지도 몇몇의 보고를 제외하고 주관절 관절경에 대한 관심은 매우 적었다. 그 후 주관절 관절경은 관절경 기구들의 발달과 소관절을 위한 소구경 관절경의 발전과 함께 하였다. 1985 Andrew와 Carson이 supine position에서 전외측, 전내측 그리고 후외측 삽입구를 이용하여 주관절을 관찰하였으며 1989년 Poehling은 후방 주관절 접근이 용이하도록 prone position으로 관절경을 시행하였고 최근 새로운 접근 방법 및 확대된 적응증에 대한 보고가 점점 늘어나고 있다. 주관절 관절경의 합병증은 적지만 주관절 주변의 해부학적 구조물에 대한 정확한 이해를 가지고 있어야 심각한 합병증을 발생을 예방할 수 있다.

Purpose: Understanding elbow biomechanics is necessary to understand the pathophysiologic mechanism of elbow injury and to provide a scientific basis for clinical practice. This article provides a summary of key concepts that are relevant to understanding common elbow injuries and their management. Materials and Methods: The biomechanics of the elbow joint can be divided into kinematics, stability and force transmission through the elbow joint. Active and passive stabilizers include bony articular geometry; soft tissues provide joint stability, compression force and motion. Results and Conclusion: Knowledge of elbow biomechanics will help (i) advance surgical procedures and trauma management, (ii) develop new elbow prostheses and (iii) stimulate future research.

Total elbow arthroplasty is a relatively rare procedure compared with total knee or total hip arthroplasty. Total elbow arthroplasty for bony ankylosis is even rarer, and the results are often unsatisfactory. We report a patient who gained good mobility of the elbow after total elbow arthroplasty for the treatment of fractured arthrodesis site with which the patient had lived with for 12 years.

The purpose of this article is review about the use of ultrasonography in the evaluation of the elbow joint. Ultrasonography has several key advantages in elbow joint, including easy assessment of target structure in elbow joint and ability to perform real time dynamic examination and to compare with opposite site. Ultrasonography is easy available to visualize abnormalities affecting tendons, muscles, ligaments, bursae, and occult fractures around the elbow joint and also allows accurate assessment of ulnar nerve in cubital tunnel. The role of ultrasonography will increase further with regards to evaluation of soft-tissue abnormalities of the elbow joint.

Purpose: Management of the stiff elbow by arthroscopic procedure is an effective but technically demanding. Our purpose was to review the specific arthroscopic maneuver which can be useful for the stiff elbow. Materials and Methods: A stiff elbow that is refractory to conservative treatment can be treated surgically to remove soft tissue or bony blocks to motion. The olecranon or coronoid osteophyte and loose bodies have been removed arthroscopically with good results and rare complications. Results and Conclusion: For the successful arthroscopic management of elbow stiffness, it need to knowledge and skills for debride contracted tissue and preserve vital anatomic structure.

Purpose: The current study reports the clinical results of total elbow arthroplasties (TEA) which were Performed on patients with poor clinical and radiological results after initial surgeries for elbow fractures or dislocations. Materials and Methods: The clinical outcomes of twelve consecutive patients who underwent TEA after failed surgeries for elbow fractures or dislocations from january, 1995 to December, 2005 were evaluated. The initial diagnoses were distal humeral fractures in 8 cases and fracture-dislocations in 4 cases. The Mean period from the initial operations to the TEAs was 12 months. The mean folloow up period after TEA was 43 months. Results: The mean range of motion, in terms of active extension, activeflexion, supination, and pronation, improved from $14.2^{\circ}$, $96.7^{\circ}$, $50.8^{\circ}$ and $53.3^{\circ}$ to $5.4^{\circ}$, $122.1^{\circ}$, $63.3^{\circ}$ and $67.5^{\circ}$, respectively (p<0.05). RAdiolucent lines were found in 3 cases, which were 1 case of type 3, and 2 cases of type 4. All three loosening cases underwent revision TEAs. The mean postoperative Mayo elvow performance score was 79 point. There were 6 cases of excellent, 2 cases of good, and 4 cases in poor. Conclusion: Good clinical results were obtained after TEA performed in failed surgeries for elbow fractures of dislocations.

Purpose: To evaluate the ultrasonographic findings of the elbows on group screening of middle school baseball players. Materials and Methods: Ninety-three players (age: 12-15, mean 13.5 years) of four middle school baseball team were evaluated with bilateral elbow ultrasonographies in the field regardless of elbow pain. Medial and anterolateral ultrasound examination of the both elbow were performed in the field to detect any abnormalities including medial epicondylar separation or fragmentation and capitellar osteochondritis dissecans respectively. We analyzed the relationship among elbow pain, physical findings and sonographic abnormalities and the differences of sonographic abnormalities between pitchers and fielders. Results: Thirty-six of 93 (39%) players had sonographic abnormalities of elbow in dominant arm, 30 with medial epicondylar apophyseal separation or fragmentation, 2 with osteochondritis dissecans, 4 with both lesions. Twenty-nine of 37 (78%) players with elbow pain had sonographic abnormalities. On physical examination, players with medial epicondylar abnormalities had medial epicondylar tenderness (59%) and pain on valgus stress test (52%), and 5 of 6 (83%) players with osteochondritis dissecans showed flexion contracture more than $5^{\circ}$. The incidence of medial epicondylar abnormalities between pitchers and fielders was statistically not significant but osteochondritis dissecans was more prevalent in pitchers (p<0.05). Conclusion: Elbow sonography is a simple and useful screening tool in the field and also effective for early detection of medial epicondylar abnormalities or osteochondritis dissecans that could be the main causes of elbow pain in adolescent baseball players.
