Radiographic assessment of cup migration in bipolar hip arthroplasty: intra-observer and interobserver errors and tolerance limits.
Statistical methods were used to calculate the possible observer error in measuring cup migration in bipolar hip arthroplasty from follow-up radiographs. Finding the "tolerance limits" by such methods helped in assigning the true significance of any observed change.

The muscles and tendons of the rotator cuff of 37 fixed cadaver shoulder joints were dissected. In ten shoulder joints devoid of gross pathological lesions it was found that the supraspinatus muscle was inserted at two points--mainly into the major tubercle and partly into the lesser tubercle of the humerus. In one case of six, an additional insertion clearly occurred in a shoulder joint with rotator cuff tear.

Diagnosis and treatment of retroperitoneal hematoma in multiple trauma patients.
From 1984 to 1991 20 multiple trauma patients with pelvic fractures and retroperitoneal bleeding from pelvic vessels underwent angiographic localization and embolization of massively bleeding arterial vessels. Nine patients survived (multiple trauma index grade III, Hanover polytrauma index), three patients with very severe injuries died immediately (multiple trauma index grade IV). ⋯ This underlines the importance of early angiography in multiple trauma patients with pelvic fractures and persisting hemorrhage. Embolization has proven to be effective in the treatment of such injuries.

Comparative StudyOsteochondrosis dissecans of the talus. Comparison of results of surgical treatment in adolescents and adults.
Clinical results in two groups of patients treated for osteochondrosis dissecans tali were examined in a follow-up examination: adolescents up to age 16 years versus adults. Thirteen patients were reexamined in each group. Clinical comparison revealed distinct differences between the groups. ⋯ In conclusion, adolescents without any signs of joint locking or loose body formation should first be treated conservatively. The older the patient the shorter the period of nonsurgical treatment should be. In cases of increasing stages, joint locking, or formation of loose bodies surgical intervention is recommended.

Computed tomography in traumatology with special regard to the advances of three-dimensional display.
There is a variety of methods to aid in the diagnosis of fractures requiring operative treatment. A computer program that produces pseudo-three-dimensional (3D) images from sets of axial computed tomograms is used for examining fractures in areas of complex skeletal anatomy. ⋯ The 3D information can be used to define the size, shape, and location of the various fracture types. We have used the technique in more than 500 patients with injuries to the skull, spine, acetabulum, sternoclavicular joint, shoulder, knee, and calcaneus and are able to demonstrate the benefit of special investigation protocols.
