[Indications and technic of external fixation in acute management of polytrauma].

The application of external fixation in the multiple injured patient permits rapid stabilisation of fractures and excellent preservation of soft tissue without an additional systemic load after traumatic shock. Acute fixation in the primary care is achieved by particular constructions for the pelvis and femur and modifications of standard-techniques for the tibia and joint-transfixation. In most cases secondary completions or alterations in the method of treatment are necessary.

[A treatment concept using external transfixation in unstable defect trauma of the knee joint].

The main problems in the treatment of severe knee injuries with extensive soft tissue damage, ligamentary lesions and compound fractures consist in the high risk of infection and complex instability of the joint. 20 patients suffering such type of trauma were treated by a schedule comprising an extensive debridement and a combination of minimal internal osteosynthesis and external transfixation. Secondary operations were always performed as a second look in all patients and various surgical reconstructions of the soft tissue coverage under continuous protection of the external fixation. Most patients obtained satisfactory functional results, only 2 cases ended up with arthrodesis due to deep infection.

[Spontaneous and simultaneous bilateral quadriceps ruptures in hyperparathyroidism].

A report of a case of bilateral spontaneous and simultaneous quadriceps tendon ruptures and a review of the world literature is given. Chronic renal failure and its sequelae, hemodialysis and particularly hyperparathyroidism are associated with all such patients under the age of 50. Diagnosis should be made early since primary suture of the tendons is the treatment of choice.

[Intraluminal balloon occlusion of the aorta in traumatic massive hemorrhage].

Management of massive abdominal hemorrhage is a major challenge in trauma care. In this clinical setting high aortic blockade is known to be effective, as it stops arterial bleeding and restores the vital central circulation. Balloon occlusion of the descending aorta provides an alternative to thoracotomy with aortic cross-clamping, thereby avoiding this major surgical procedure. For introduction of the balloon the recommended technique is cut-down and insertion of the balloon to the femoral artery. More research and clinical experience are needed to define useful indications and to explore the long-term consequences of aortic balloon occlusion.

Serum mediated depression of chemiluminescence response of granulocytes in hemorrhagic shock.

CL of PMNL was decreased in the early stage of hemorrhagic shock in the rat if evaluated from whole blood. When standardized PMNL were incubated with plasma of different shock states the same serum--mediated depression was observed. In all stages killing activity of PMNL per se from arterial blood (after passage of pulmonary endothelium) was nearly unchanged if measured in standardized pool plasma. Furthermore in the prefinal stage of uncompensated shock highly activated PMNL were obtained. These results support the hypothesis that plasmatic--cellular interactions play an important role in depression of killing activity of PMNL already in early hemorrhagic shock. Actual concepts mention protein cleavage products, fluid phase C3b and prostaglandins as potential mediators of this serum--mediated suppression.

[The Graner capitate interposition arthroplasty in lunate malacia].

In capitate interpositional arthroplasty (Graner II) the necrotic lunate bone is removed and the congruity of the proximal carpal row is restored by interposition of the proximal half of the capitate. The carpal bones are fused except for the scaphotrapezial joint. In this fashion carpal instability can be safely treated. Good results are achieved for both grip strength and relief of pain. Motion is restricted but with a useful range of motion remaining. The arc of remaining motion can be shifted into extension through the use of an opening wedge osteotomy of the capitate. Capitate interpositional arthroplasty without an intercarpal arthrodesis has poor result because of remaining carpal instability.

[Principles of primary functional fracture treatment].

The main characteristic feature of primary functional treatment of fractures is that all parts of the affected segment of the locomotor apparatus are essentially functional again within a week after the trauma has been sustained, even without any internal splinting. Stable cancellous bone compression, fractures that are stabilized by a pronounced muscular sheath and certain fractures affecting the shafts of the long tubular bones are all indications for application of this method, providing there is no concomitant high-grade soft tissue damage. Adjuvant analgesia is an important basis of the therapy; others are exercises under the supervision of a physiotherapist and the adaptation of supporting splints and cuffs. The primary functional treatment regimen has few complications, and when it is applied only in situations where it is genuinely indicated and is competently supervised, the clinical results are excellent.

[Results of the surgical treatment of distal femoral fractures].

In a follow-up of 97 operated distal femoral fractures good and satisfactory results were found in 64% of the cases. 22% unsatisfactory and 14% poor findings attribute mainly to the comminuted supracondylar fracture types. More than half of the patients were multiple injured. In 83% of the cases the internal fixation was obtained by the use of the condyle buttress plate.

[Surgical treatment of tumor-induced destruction of the spine].

Surgery for treatment of destructions of the spine varies depending on localization and tumour status. If the body of the vertebra is affected, the ventral approach allows radical tumour resection as far as possible. The following stabilization is effected by filling the defect and carrying out osteosynthetical fusion. Of 38 patients, three had benign tumours, whereas ten patients had primary malignant and 25 had metastatic tumours. The results show that surgical treatment is justified also in palliative indications; although survival time is not prolonged, the quality of life can be improved.

[Management of complex pelvic injuries].

Compound pelvic fractures can be mastered only by means of an active surgical procedure. If the shock cannot be controlled by conservative treatment, early angiography followed by embolisation should be done. Alternatively to embolisation, control of haemorrhage can be achieved by specific ligation, reconstruction of the vessels or tamponade with mandatory laparotomy. Septic complications can be prevented by a liberal indication of derivative colostomy with irrigation of the rectal segment by copious amounts of saline solution, by suprapubic urinary drainage and meticulous "debridement" of soft tissue. The procedure is presented in detail.
