[Hip degeneration].

Hip degeneration is typically easily diagnosed, based on the combination of clinical findings and plain films showing the four classifical findings: joint space narrowing, osteophytes, subchondral sclerosis and subchondral cysts. Some degenerated hips may have misleading features such as when joint space narrowing is mainly posterior or the main finding is a large subchondral cyst. Rapidly destructive coxopathy results in joint space narrowing and joint destruction over a few months.

[Plain films of pelvis].

Plain films of the pelvis remain informative and allow most of the diagnoses. Assesment of the hip joint space, bone and subchondral structures, sacrum as well as sacroiliac joints is made on the AP view. Oblique views are useful.

[Imaging of traumatic injuries of the elbow].

Traumatic injuries to the elbow may result in dislocations and/or fractures of the distal humerus or proximal radius or ulna. Multiple and associated lesions are common. Plain radiographs usually allow accurate diagnosis.

[Hyperechoic rotator cuff tendon tear].

Purpose: To describe unusual rotator cuff tendon tears which are hyperechoic at ultrasonography (US).

Materials And Method: We retrospectively reviewed the shoulder US examinations of 100 patients with rotator cuff tear demonstrated by CT arthrogram with bursography. We included in this study hyperechoic foci without surrounding hypoechoic zone.
