Comparative Study[Validation of the DTP-3 system for noninvasive spinal shape measurement by comparison with X-ray examination].
Repeated measurements of the spine are absolutely necessary in children and adolescents affected by spinal deformities especially during their growing-up periods. To avoid risks of tissue damage from x-ray exposure, several methods for non-invasive measurement of the spinal curvature have been developed. One of them is the DTP-3 position system allowing for a three-dimensional measurement of anatomical landmarks (spinous processes) and the calculation of curvature angles in both the frontal and sagittal planes. We were interested to know whether the DTP-3 was precise enough to determine the true spinal curvature. ⋯ In this study we report good concordance between noninvasive and x-ray examinations of a modeled spinal deformity in terms of both angle and linear measurements. The same results were obtained for angle measurements in a group of patients with scoliosis up to 40°. Based on this study and our previous data we believe that the DTP-3 system can be introduced into clinical practice.

Based on a retrospective analysis, the authors present their experience with treatment of subtalar dislocation of the foot. ⋯ A subtalar dislocation of the foot involves simultaneous dislocation of the talocalcaneal and talonavicular joints. It is a rare injury accounting for about 1 to 2% of all traumatic dislocations. It may occur as medial, lateral, anterior or posterior subtalar dislocation. The results of treatment depend on several factors, such as the type of dislocation (medial and open dislocations are at higher risk), associated injuries, or damage to deep skin layers, and also on an exact diagnosis, early and accurate reduction and sufficiently long foot immobilisation.

[Arthroscopically-assisted osteosynthesis of calcaneal fractures: clinical and radiographic results of a prospective study].
The aim of this prospective study was to evaluate the clinical and radiographic results in a group of patients with calcaneal fractures treated by means of minimally invasive, arthroscopically-assited osteosynthesis. ⋯ In our group of patients with predominantly less severe types of calcaneal fractures, the quality of post-operative fracture reduction, as a result of minimally invasive, arthroscopically-assisted osteosynthesis, appeared to be comparable with open techniques. The observed complete bone healing and absence of soft-tissue problems could present a surgical option to treatment nihilism in patients contraindicated for ORIF techniques.

[Post-operative retransfusion and intra-operative autotransfusion systems in total knee arthroplasty. A comparison of their efficacy].
The aim of the study was to compare the effect of post-operative retransfusion with that of intra-operative autotransfusion in non-anaemic patients undergoing total knee arthroplasty (TKA). ⋯ The use of either of these systems has proved to be a simple and safe method of reducing the need of allogeneic blood transfusion in the TKA procedure. While the post-operative retransfusion system facilitates the return of drained blood only, the more efficient "cell-saver" technology collects blood shed during both intra- and post-operative periods and allows for erythrocyte mass retransfusion during and after surgery. Since the administration of allogeneic blood was required in less than 10% of the patients receiving intra-operative autotransfusion, this system was adopted as a more efficient method in routine TKA procedures.

[Evolution of the technique of arthroscopic reinsertion of the rotator cuff. Our experience from the years 1998 to 2008].
A rotator cuff tear is a relatively frequent cause of pain and restricted motion of the shoulder. Some orthopaedists believe that any attempt at rotator cuff reconstruction will fail. The aim of this paper is to present our experience with arthroscopic reconstruction of rotator cuff tears. ⋯ The arthroscopic reconstruction of a rotator cuff tears results in a marked relief of pain and improved joint function. An ideal candidate for this treatment should show passive free motion at the shoulder joint, no clinical signs of bursitis, and mobilisable tendon stumps of the torn rotator cuff. In addition, these patients should be highly motivated for post-operative rehabilitation. A suture device was most effective in rotator cuff repair. For good fixation into the bone it is recommended to use special implants that have a minimal risk of dislodgement or anchor thread failure.
