Brief Summary

• Elbow pain is any type of pain that comes from structures in the elbow joint and/or in structures adjacent to the elbow joint. elbow is a complex joint; it allows to both extension and flexion, as well as rotation hand and forearm. Since most movements are a combination of these actions, Elbow pain is often caused by overuse, but in general, elbow joint is much less prone to wear-and-tear damage than are many other joints. The causes of elbow pain are numerous. Most elbow pain is due to overuse or strain on the elbow joint components, but some causes are due to trauma, infection, and/or autoimmune processes and neoplasm. Risk factors for elbow pain are numerous and range from engaging in repetitive activities and participation in sports to those associated with infection, trauma, and rheumatoid arthritis. Other adjacent structures associated with elbow pain include the shoulder, upper arm, forearm, and wrist and hand joints.

Detailed Description

* Health-care professionals diagnose elbow pain mainly by a patient's history and physical exam. Radiologic techniques such as X-ray ,US,CT and MRI are often used to delineate the elbow structures involved. Conventional radiography remains an essential initial test in the evaluation of the elbow and its disorders. One must be familiar with the pertinent anatomy, early developmental changes, and the biomechanics of this complex joint to appreciate subtle injury patterns and articular disorders. In some cases, radiographic imaging will point to the need for further evaluation with CT, MR, or sonographic imaging High-resolution ultrasound is well suited for evaluating the elbow. Ultrasound is growing in popularity and fast becoming another modality that the radiologist can use to help diagnose elbow pathology. ultrasound offers focused and real-time high-resolution imaging of tendons, ligaments, and nerve structures. Its advantages include the use of safe nonionizing radiation, accessibility, and cost effectiveness. Ultrasound is also useful in therapeutic guided injections for its multiplanar capability and clear visualization of major vessels and nerves.

* MR imaging provides clinically useful information in assessing the elbow joint. Superior depiction of muscles, ligaments, and tendons as well as the ability to visualize nerves, bone marrow, and hyaline cartilage directly are advantages of MR imaging relative to conventional imaging techniques. These features of MR imaging may help to establish the cause of elbow pain by accurately depicting the presence and extent of bone and soft-tissue pathology. Ongoing improvements in surface coil design and newer pulse sequences have resulted in higher quality MR images of the elbow that can be obtained more rapidly. This is especially important in MR as the imaging tool that shows a highest soft tissue resolution among other imaging techniques. Recent clinical experience has shown the utility of MR imaging in detecting and characterizing disorders of the elbow in a a noninvasive fashion.

Primary Outcome Measures

Name	Time	Method
Number of participants with non-traumatic painful elbow is diagnosed by MRI Using sensitivity, specificity and accuracy tests which used for .	6 Months	:46 cases, is calculated using the Open Epi software programme, version 2.3.1. previous study reported the expected rate 40%. estimated the increase into 40% (80%). using two sided chi-square (x-2) test with alpha (95%). total sample size of at least (46) using 80% power will be needed (odd ratio=0.17). assuming a rate of drop-out of (10%), so, will include (46) cases.
