The goal of blood management in orthopedic and trauma surgery is to minimize exposure to allogenic blood transfusion in elective surgical procedures. Pre-, intra- and postoperative techniques are available. In a retrospective study at our department we could show, that postoperative reinfusion in primary knee arthroplasty is an effective way to avoid allogenic blood transfusion. ⋯ Group II required per patient 1.3 units of allogenic blood (totally 26 units), group I needed only 0.25 units of allogenic blood per patient (totally 5 units) by using the same guidelines for transfusion in both groups. There were similar preoperative and postoperativ hemoglobin and hematocrit levels in both groups. We recommend the use of postoperative reinfusion in addition with other blood saving techniques to reduce allogenic blood transfusion in primary knee arthroplasty.

For young athletic patients with a primary traumatic shoulder dislocation a surgical treatment is recommended. The operation of choice is the Bankart-Repair. ⋯ In the surgical treatment of a traumatic shoulder dislocation, the open Bankart-Repair remains the "gold standard". In reviewing the literature, arthroscopic Bankart-Repair has not been shown to be equal or superior to the open technique.

Malposition of extraosseous or intra-articular screws, e.g., in osteosyntheses of joint fractures or in the vicinity of joints, frequently remains undiscovered in intraoperative fluoroscopy and is only recognized on postoperative computed tomography (CT) scans. The aim of the study, therefore, was to assess the value of a new mobile C-arm three-dimensional imaging device in comparison with fluoroscopy, conventional radiographs, and CT scans using an extremity model. Screws were inserted ventrally in four anatomic lower leg specimens without talus fractures parallel to the longitudinal axis to simulate surgical management of fractures of the talus. ⋯ The quality of information acquired with the SIREMOBIL Iso-C3D was equal to that of the CT examinations, although image quality was considered inferior to fluoroscopy, conventional radiography, and CT (p < 0.001). In contrast to the previous procedure with intraoperative fluoroscopy and subsequent postoperative X-ray control, the results obtained with the SIREMOBIL IsoC3D were superior. The SIREMOBIL Iso-C3D is useful for the intraoperative diagnosis of small joints with few artifacts producing osteosynthesis material, i.e., for recognizing the position of screws in the region of glenoid surfaces.

The objective was to evaluate long term results after removal of a popliteal cyst with special focus on recurrence rate and associated intraarticular pathology. Between 1982 and 1995 71 patients (23 women and 48 men between 21 and 75 years of age) underwent removal of a popliteal cyst. An additional arthroscopy of the knee joint was carried out in 51 consecutive patients starting in 1988. ⋯ It depends strongly on the type of associated intraarticular pathology. Especially grade III and grade IV chondral lesions correlated significantly with recurrence of a popliteal cyst after removal. Therefore, the main goal of surgery should be the successful treatment of associated intraarticular pathologies.

The case of an 22-year-old man is presented, who sustained a dislocated fracture of the left acromion process and a not dislocated fracture of the left scapular body with a large subcutaneous décollement as well as a dammage of nervus axillaris occurring during a traffic accident. After resuming diagnostics by means of CT, a tension banding of the ventral part of the acromion and a plate osteosynthesis of the dorsal part was performed. 7 weeks after injury neurolysis of nervus axillaris has been done. 4 months after accident the patient shows a satisfying functional result in the Constant score. Diagnostic, treatment and functional results after operative treatment of dislocated fractures of the acromion are shown and discussed.
