Comparative Study
[Prognosis of proximal radius fractures in the growth period].
Fractures of the proximal radius in children may lead to deformities of the radial head and functional disturbance of pro- and supination. However, traumatization is not only caused by the injury itself, but may also occur secondary to surgical reduction, manipulation of fracture fragments and excessive physiotherapy. In a prospective long-term follow-study (2-20 years after trauma) of 38 children with displaced proximal radius fractures we found functional disturbances in 11% of children only. ⋯ Functional impairment was mainly seen after open reduction or secondary growth disturbances. On follow-up radiographs all conservatively treated fracture angulations up to 60 degrees had corrected themselves spontaneously. In view of the high complication rates after open reduction and the poor functional results, as well as the inconvenience for the pediatric patient and the economic aspects, we recommend a primary conservative treatment concept of proximal radius fractures in children.

To calculate canal compromise and decrease of midsagittal diameter caused by retropulsion of fragments into the spinal canal we analyzed the pre- and postoperative computed tomographies of 32 patients with unstable thoracolumbar burst fractures treated by USS (universal spine system). Our intention was to examine the efficiency of ultrasound guided repositioning of the dispaced fragments which was performed in all 32 cases. We found a clear postoperative enlargement of canal area (ASP preoperatively 55%, postop. 80%) and midsagittal diameter (MSD preop. 58%, postop. 78%). 10 of 13 patients presented a postoperative improvement of neurological deficit, no neurological deterioration occurred. ⋯ Below L 1 the spinal canal is greater than between Th 11 and L 1, so a more important spinal stenosis is tolerated. In case of unstable burst fractures with neurological deficit the ultrasound guided spinal fracture reposition is an effective procedure concerning the necessary improvement of spinal stenosis: an additional ventral approach for the revision of the spinal canal is unneeded. In fractures without neurologic deficit the repositioning of the displaced fragments promises an avoidance of long-term damages such as myelopathia and claudicatio spinalis.

Non-unions in the proximity of the elbow are very rare and in most cases caused by mistakes in initial treatment. Reconstruction after pseudarthrosis of the elbow continues to pose a challenge for any surgeon. The aim of our study was to analyze the initial mistakes and to underline the most important aspects of reconstructive surgery. ⋯ In 24 out of 27 cases a re-osteosynthesis, in 12 an arthrolysis, in 7 a neurolysis and in 2 cases an arthroplasty was needed. The patient could return to work an average 18 weeks after the operation and 53 weeks after injury. The initial complaints were reduced in 24 of 27 cases, with a significant improvement in the ROM and functional outcome according to the Mayo Elbow Performance Index.

Review Case Reports
[Must the accident victim be protected from the emergency physician?].
Quality control in preclinical medical care has become a matter of concern in recent years. In order to evaluate the quality of treatment one has to set standards. Most of the current standards were defined by different preclinical care organisations and are also accepted in the unique emergency medical care protocol used in the Federal Republic of Germany. ⋯ Insufficient application of resuscitation volume (< 2500 ml on admission) was evident in 17% of all documented patients. According to our results, the initial evaluation of severity of injury is still a major problem and leads to wrong decisions for treatment. Although the qualification of ambulance physicians has been standardized for some years, there are still clear deficits in the preclinical management of trauma patients that need to be targeted.

Between 1982 and 1993, 65 amputation and amputation-like injuries in the upper arm (n = 18), proximal and middle forearm (n = 32) and distal forearm and wrist level (n = 15) were treated in our institution. The overall survival rate in our series was 92.3% (60/65). In 3 of 65 cases early secondary amputation because of vascular failure was necessary. ⋯ Taking grades I and II results together, a "functional extremity" could be reconstructed at the upper arm level in 25%, proximal forearm 30%, and the distal forearm in 58%. The main advantage of replantation/revascularization of the upper limb is the possibility of restoring some sensitivity to the hand in addition to partial motor recovery, which always provides twice as much individual motor function as is offered by any type of prosthesis currently available. The higher cost and number of operations needed, as well as the longer postoperative care and longer disability time after replantation/revascularization are nevertheless justified by the significant increase in quality of life.
