[The nature and mechanogenesis of pelvic bone fractures in children from exposure to the impact from blunt solid objects in the pubic symphysis area at different angles to the plane of the pelvic girdle].

Forty-four cases with pelvic injuries in children resultant from strikes inflicted in the pubic symphysis from the front with blunt hard objects (30 experimental observations, 230 fractures, and 14 expert cases, 119 fractures) are analyzed. The results indicate that in children subjected to strikes in the pubic symphysis with blunt objects it is possible to determine the mechanogenesis of injuries, and, hence, the angle between the direction of traumatic force and pelvic plane (in the pelvic ring plane or at a 45 or 90 degrees angle to it).

[Detection of occult fractures of the pelvic bones by roentgen computed tomography].

The informational value of C.T. concerning pelvic fractures is presented. Not all injuries to the hip joint and to the os sacrum can be seen on standard a.p.-projections, oblique views, special projections or conventional tomography. 17 typical examples have been selected from young patients with multiple injuries. C.T.-findings concerning fractures of the hip joint, of the os sacrum and of hidden pelvic fractures are described. Emphasis is placed on careful radiological analysis of fractures with special regard to the planning of conservative or operative treatment and also on the later functional results following fractures of the hip joint.

Female pelvic bone marrow: serial MR imaging before, during, and after radiation therapy.

PURPOSE: To study early changes in irradiated pelvic and adjacent nonirradiated bone marrow with T1-weighted magnetic resonance (MR) and short inversion time inversion-recovery (STIR) imaging. MATERIALS AND METHODS: The bone marrow of 31 women with advanced cervical carcinoma was studied in 161 MR examinations before, during, and 7 weeks after radiation therapy. Two radiologists visually evaluated the marrow signal intensity (MSI) on T1-weighted and STIR images. RESULTS: Changes in irradiated and adjacent nonirradiated marrow were shown on T1-weighted images in 31 (100%) and 18 (58%) of the 31 patients, respectively. MSI changes on images were observed as early as 8 days after the start of radiation therapy and occurred more frequently in irradiated than in adjacent nonirradiated marrow. In the irradiated regions, a complete fatty marrow was seen on T1-weighted images obtained 6-8 weeks after the start of radiation therapy in 28 (90%) of the 31 patients. CONCLUSION: T1-weighted and STIR images obtained during and soon after radiation therapy complement each other in showing changes in bone marrow.

[Treatment of multiple injuries of the pelvic bones (with rupture of the pubic symphysis) by stabilization of the latter using the Zespol method].

Fractures of the pelvis with disruption of the symphysis ossis pubis and, especially, the surgical treatment: stabilization of the symphysis ossis pubis by various kinds of the use of the ZESPOL stabilizers have been presented. The difficulties in the conservative treatment in 2 patients with multiple fracture of the pelvis, in whom the correct position of other injuries of the pelvis depended on the stabilization of the symphysis ossis pubis, have been presented in detail. In the discussed patients, it was obtained by the ZESPOL method employed in one patient subcutaneously and in the other externally. This is the first report about the use of the ZESPOL stabilizer in the treatment of symphysis ossis pubis disruption. It provides good conditions of healing of the symphysis ossis pubis ligaments, makes possible earlier mobilization and standing position of a patient. The presented employment of the ZESPOL stabilizer in the treatment of symphysis ossi pubis disruption widens the range of the application of this stabilization method.
