Comparative Study
[Bone defect reconstruction in bone sarcoma surgery : Tumour endoprosthesis versus biological reconstruction].
Primary bone sarcomas typically arise in the long bones and the pelvis of children and adolescence but may also occur in adults. Meta/diaphysial tumour involvement resulting in the necessity of a joint replacement is more common than diaphysial tumour sites. ⋯ Surgical treatment of bone sarcoma requires broad-based experience of the oncological surgeon. Knowledge of the different surgical technics and reconstruction methods is decisive to offer the individual patient the best oncological and functional outcome.

The aim of the study was an estimation of the incidence and clinical aspects of emergency room (ER) parameters of penetrating abdominal injury patients with bowel evisceration. ⋯ Evisceration itself is not a cause for increased mortality or cardiovascular instability seen in the ER. There is ample time for diagnostic procedures before laparotomy is performed.

In the context of acute knee dislocations, suture repair of ruptured cruciate ligaments leads to good clinical results in 80% of cases. Disadvantages are low primary stability and subsequently secondary elongation of the sutured ligaments. In the present study, we compared primary stability of suture repair, reinforced by different suture augments, to cruciate ligament reconstruction. ⋯ Augmented suture repair provides significantly higher stability compared with isolated suture repair and reconstruction with hamstring tendons. The concept of ligament bracing could be a promising future treatment option in acute knee dislocations. Clinical results remain to be seen.

Megaprostheses are frequently used after segmental resection of bone sarcomas, bone metastases, and in large osseous defects in revision arthroplasty. ⋯ Complications with the use of megaprostheses can be successfully treated by revision surgery in most cases.
