팔꿈치는 3 개의 뼈의 관절을 포함하는 힌지 관절입니다 : 상완골, 반경 및 척골. 어깨보다 훨씬 안정된 관절이며, 그 때문에 팔꿈치는 운동 범위가 적습니다. 팔꿈치와 그 구조는 특히 반복적인 움직임으로 상당한 부상을 입기 쉽습니다. 측면 및 내측 에피톤디리터티스(테니스 팔꿈치와 골퍼의 팔꿈치라고도 함)는 두 가지 일반적인 진단이며 종종 직업 활동의 결과로 발생합니다.
팔꿈치를 검사 할 때, 전체 어깨와 팔꿈치를 검사 할 수 있도록 충분한 옷을 제거하는 것이 중요합니다. 부상당한 팔꿈치를 관련없는 쪽과 비교하는 것이 중요합니다. 팔꿈치의 체계적인 평가에는 검사, 심포지션, 운동 범위(ROM) 테스트 및 특수 검사를 포함하며, 인대 안정성을 평가하는 기동과 서피론디리티스로 인한 통증을 강조하기 위한 스트레치 테스트를 포함합니다.
1. 검사
팔꿈치의 검사는 앉는 자세에서 환자와 함께 단계적 접근 방식을 따르는 것이 가장 좋습니다. 환자가 표면 해부학을 보고 관련되지 않은 쪽에 비교할 수 있도록 충분한 의복을 제거하는 것이 중요합니다. 시험은 관련자와 관련되지 않은 팔꿈치 사이의 비대칭을 찾고, 검사로 시작해야합니다. 다음으로, 주요 구조물의 심포메이션은 부드러움, 붓기 또는 기형을 찾고, 행해지합니다.
The elbow joint enables mobility of the upper extremities and allows precise control of the hand's position in space.
The anatomy of the elbow is complex. It is a hinged joint formed by articulations between three bones: humerus, radius, and ulna. It is stabilized by the lateral and medial collateral ligament complexes.
The muscles involved in elbow movement are classified as per their function. The flexor group includes biceps brachii, brachilais, and brachioradialis. Extension is a function of posterior muscles-triceps brachii and anconeus. Pronation involves brachoradilais and pronator teres. Lastly, supination engages biceps brachii, brachoradilais, and supinator muscles.
In addition, the bony prominences of the distal humerus-called the lateral and medical epicondyle-form the attachment sites for muscles involves in wrist and hand movement. Lateral epicondyle is where the extensors attach and medial epicondyle is the attachment site for the flexor muscles. Inflammation surrounding these epicondyles, or epicondylitis, is one of the common reasons of elbow pain. Lateral epicondylitis is frequently seen in tennis players, giving this condition a colloquial name - the "tennis elbow". Similarly, medial epicondylitis is commonly seen in golfers, and therefore known as the "golfer's elbow".
The source of the elbow pain can be identified based on the patient history and careful physical examination, and here, we will review the steps of this exam in detail.
Systematic elbow examination starts with inspection and palpation. Before starting the exam wash your hands thoroughly. For inspection, ask the patient to sit on the exam table and request them to remove enough clothing so that the entire shoulder and elbow are exposed.
First assess the size of the elbows and look for atrophy and swelling, and check for redness or warmth. The joint swelling may appear anteriorly at the brachial fossa, but the more common site is in posterior region, in the olecranon bursa. Next, assess the carrying angle, which is formed by the upper arm and the forearm in the anatomic position. The carrying angle is normally 5-10° in males and 10-15° in females, and can be altered by prior trauma or infection.
Now move onto palpation, which is helpful in localizing the pain to the anterior, posterior, medial, or lateral region. Starting at the anterior elbow, first find the biceps tendon in the cubital fossa, which feels like a tight cord. From there move a bit medially to assess for tenderness over the median nerve. And palpate over the anterior joint capsule, which can be a source of pain when inflamed.
After that assess the posterior elbow. Start by palpating the triceps muscle along the posterior upper arm. Move downwards until you reach the prominent bump at posterior elbow called the olecranon process of the ulna. From there move your fingers superiorly to locate the olecranon fossa, which is felt as a small depression. Also examine the area posterior to the proximal ulna-the "olecranon bursa", which can only be felt if inflamed or swollen.
Next, assess the medial side. First, palpate the medial epicondyle on the distal humerus. Then, feel the tendons in the same location that belong to the wrist flexor and pronator muscles. Subsequently, palpate from the medial epicondyle to the olecranon to assess the MCL, which lies deeper than the flexor and pronator muscles. Lastly, just above the MCL, palpate the ulnar nerve, which follows the same path as the MCL. Tapping over this nerve may cause uncomfortable sensation when inflamed. This is known as the "Tinel's Sign".
Finally, examine the lateral aspect of the elbow. Start by palpating the lateral epicondyle, followed by the tendons of the extensor and supinator muscles, which are attached to the lateral epicondyle. Just beyond the epicondyle you can find the radial head, and while supinating and pronating the wrist you can feel the radial head and the articulation at the radial-capitellar joint. Finally, feel for tenderness in the area four fingerbreadths distal to the lateral epicondyle. Pain in this region suggests compression of the posterior interosseous nerve.
Next, we will demonstrate how to test the range of motion for the elbow. This should be evaluated by comparing between the two sides, and lack of motion may suggest a mechanical block, or stiffness due to injury or arthritis.
Start by assessing extension. Instruct the patient to fully straighten the arm. Normally the angle at full extension is 0°, since elbow is a hinged joint. Next, ask the patient to flex the arm and try to touch the hand to the shoulder. Normally, the flexion range is about 150°.
For the next test, that is pronation, instruct the patient to bend their elbows to 90° with their thumbs pointing upwards and then turn their hands inward so their palms are facing down. The normal pronation range is about 80°- 90°. Finally, to test supination, have the patient rotate their hands so that the palms face upward. The upper limit for this movement is about 90°.
Now, move on to evaluating the strength of muscles involved in the aforementioned range of motion movements. Pain with the following resisted motions is commonly due to tendonitis or epicondylitis.
Begin by instructing the patient to rotate their forearm inward as before, while you provide resistance. This maneuver assesses the pronator muscles, and it is painful in presence of medial epicondylitis, since the pronator tendons attach on medial epicondyle. Next, ask the patient to turn their forearm outward against your resistance, which tests the supinator muscles. This would aggravate pain in lateral epicondylitis due to the attachment of the supinator tendons to the lateral epicondyle.
For the following tests, instruct the patient to have their wrist straight and the palm facing down. Now, ask them to first move the hand in an upward direction against your resistance. This assesses the wrist extensor muscles that attach to the lateral epicondyle. Therefore, presence of pain suggests lateral epicondylitis. Similarly, moving the hand in downward direction against resistance examines the wrist flexors that attach to the medial epicondyle. Therefore, this maneuver aggravates the pain related to medial epicondylitis. Then ask the patient to move just their middle finger in upward direction, while you push down. This test the muscle that extends the long finger extensor and again aggravates the elbow pain caused by lateral epicondylitis. Lastly, to test the biceps and triceps, ask the patient to flex and extend their elbow against your resistance. Pain during these motions suggests tendonitis.
Finally, let's review a few special tests performed to diagnose the common elbow disorders. First group of these are known as the Stretch Tests. Take the patient's hand and passively flex and pronate the wrist. This will aggravate the pain related to lateral epicondylitis. Next, passively stretch the patient's wrist into extension followed by supination. This will aggravate the pain of medial epicondylitis.
The final few maneuvers of this exam assess the pain and laxity of the medial and lateral collateral ligaments - the MCL and LCL. The MCL is injured much more commonly than the LCL. Grade the severity of ligament injury according to the table provided in the accompanying manuscript.
First, passively rotate the patient's shoulder outward, place your palm over the lateral elbow and fingers around the joint line and apply Valgus stress to assess the MCL. To test the LCL, place your palm over the medial elbow and fingers on the lateral side, and apply Varus stress.
For the last assessment, ask the patient to bend one elbow to 90° and fully supinate the hand with the thumb extended. Now ask them to use the opposite arm to grasp thumb from under the elbow, and pull it laterally. This test is called the "Milking maneuver", and is perfomed to test the MCL by creating a valgus stress. This concludes the comprehensive evaluation of the elbow joint.
You've just watched JoVE's video on the elbow examination. Here, we demonstrated the essential steps of elbow assessment and also gave examples of how the physical findings can help the clinician to reach a diagnosis. We started with the inspection and palpation of the key elbow structures, followed by testing of range of motion first actively and then against resistance. Finally, we explained how to perform a few special maneuvers to assess stability of the collateral ligaments. As always, thanks for watching!
