Supracondylar missile fractures of the femur.

We present the results of the surgical treatment of 50 supracondylar missile fractures of the femur in 48 patients wounded in the territory of the former Yugoslavia in the period June 1991-October 1995. The injuries were caused by bullets in 28 (58.3%) patients and by fragments of mines or other explosive devices in 20 (41.7%) patients. In nine (18.0%) missile supracondylar fractures there were associated fractures of articular surfaces in the knee-joint. Neurovascular bundle injuries were present in 19 (38.0%) and vascular injuries alone in 17 (34.0%) limbs. Bone fragments were stabilized by external fixation in 43 (86.0%) and by plaster of Paris in five (10.0%) limbs. Primary reconstruction of large blood vessel was necessary in 16 (32.0%) limbs. In total eight (16.0%) above knee amputations were done. Coverage of soft tissue defects was required in 19 (38.0%) limbs. Early and late postoperative complications occurred in 26 (52.0%) limbs. Additional surgical procedures were necessary in 15 patients. Definitive results showed a large number of limb shortenings, nerve paralyses and contractures of the knee-joint.

Primary surgical treatment of war injuries of major joints of the limbs.

We present the results of primary surgical treatment of war injuries of major joints in 339 patients, wounded in the territory of the former Yugoslavia in the period June 1991-October 1995. The total number of surgically treated joints was 358. The injuries were inflicted by the fragments of explosive devices in 176 (51.9%) patients and by bullets in 125 (36.9%) patients. A single wound was present in 160 (47.2%) and several wounds in 176 (51.9%) patients; 276 (77.1%) patients had injuries of articular bone. The most frequently injured joints were knee joint 167 (46.6%) and elbow joint 72 (20.1%). Associated neurovascular injuries were present in 68 (18.9%) patients. Postoperative bone fragment stabilization was required in 254 (70.9%) joints. Stabilization was by plaster of Paris in 148 (58.2%) and external fixation in 85 (33.4%) patients. Postoperative course was uneventful in 262 (77.3%) while postoperative complications occurred in 77 (22.7%) patients. Amputations were performed in 15 (4.4%) patients. After the primary surgical treatment 254 (74.9%) patients were discharged and directed to rehabilitation or home care and 81 (23.9%) patients required additional reconstructive surgery for bone and soft tissue defects.

Interactive visualization of 3D fields and images on inexpensive workstations using VRML.

The visualization of volumetric medical images and static or time-dependent vector fields is performed on personal computers over the Web using an interactive 3D interface based on VRML and Java. The VRML client obtains field information and the surface models of examined objects from a server accessible over the Internet. Various virtual tools enable radiologists and referring physicians to visualize and manipulate complex data sets using a simple interface on low-cost computers.

Subtrochanteric missile fractures of the femur.

The treatment results of subtrochanteric missile fractures of the femur in 41 casualties are analyzed. The wounds were inflicted by infantry weapon missiles in 29 (70.7%) and by fragments of mine or explosive devices in 12 (29.3%) casualties. The associated neurovascular bundle injuries were present in 11 (26.8%) patients. Fracture stabilization was done by external fixation in 25 (62.5%): group A; and by plaster of Paris in 15 (37.5%) patients: group B. The postoperative period was uneventful in 14 (35.0%) and early or late complications occurred in 26 (65.0%) patients. Bone infection developed in six (15.0%) and fractures did not heal in four (10.0%) patients. Complications were present in 13 (52.0%) patients from group A and in 13 (86.7%) patients from group B. Delayed fracture healing and fracture nonunion were present in group A and contractures of large joints in group B. Subtrochanteric missile fractures of the femur present very severe injuries where the treatment is followed by a very high percentage of complications. External fracture fixation in this region facilitates the care, stability, early covering of soft tissue defects and early physical therapy.

[The effect of captopril on the development of adriamycin nephropathy in rats with spontaneous arterial hypertension].

The effects of captopril on morphologic changes and clinical course of adriamycin (ADR) nephropathy in spontaneously hypertensive rats (SHR) were examined. After ADR infections rats were divided into two groups: ADR-C group (n = 20) given captopril (60 mg/kg per day) and ADR group (n = 19) receiving no antihypertensive treatment. SHR were examined every 6 weeks. Captopril normalized systemic blood pressure, but failed to prevent proteinuria. It slowed down renal function deterioration in the early stage of ADR nephropathy (weeks 6 and 12), but at the end of the study both groups had the same degree of renal failure irrespectively of whether blood pressure was well controlled with captopril or hypertension persisted. Captopril slowed down mesangial expansion in the early stages of ADR nephropathy, but at the end of the study there was no statistically significant difference between these two groups. Treatment with captopril also reduced the development of glomerular sclerosis.
