The aim of this study was to quantify and compare the quality of life after multiple trauma for patients with and without posttraumatic cognitive achievement deficits. We examined 173 multiple trauma patients 2-6 years after their injury. The patients were asked to rate their quality of life according to the established measure scales Nottingham Health Profile, Spitzer Index, Everyday Life Questionnaire, to a visual analogue scale and to the new "revised Aachen Longterm Outcome Score" established in our hospital. ⋯ In spite of this, the craniocerebral trauma is no global predictor of posttraumatic quality of life. These results show that the quality of life after multiple trauma is not only influenced by approved predictors such as injury severity but also significantly by the presence of cognitive achievement deficits. The KMS seems to be an easy test to evaluate those cognitive deficits.

The therapy of acromioclavicular dislocations remains controversial. In particular, for injuries classified as Rockwood/Tossy Type III good results have been reported with different operative techniques as well as with conservative treatment. The objective of this study was to obtain data about the current treatment for Rockwood/Tossy III injuries in German trauma departments. ⋯ For more severe acromioclavicular injuries (Rockwood IV to VI) all clinics recommend an operative treatment. The operative techniques of choice for acromioclavicular injuries are K-wire fixation (37%) or a coraco-clavicular cerclage (32%). Of the latter, 73% use a resorbable material, while the remainder use wires.

Comparative Study
[Biomechanical stability with a new artificial vertebral body implant. 3-dimensional movement analysis of instrumented human vertebral segments].
The authors present a new implant for vertebral body replacement in the thoracic and lumbar spine. The titanium implant is designated for reconstruction of the anterior column in injury, posttraumatic kyphosis or tumor of the thoracolumbar spine. The instrumentation has to be supplemented by a stabilizing implant. After positioning, the implant is distracted in situ, through which best contact to adjacent end-plates and 3-dimensional stability should be provided. The possibility of secondary dislocation or loss of correction should thereby be minimized. ⋯ The posterior fixation was found to offer superior stability compared to the anterior one. Synex was at least comparable to MOSS for suspensory replacement of the vertebral body in the thoracolumbar spine. The evidence of higher biomechanical stability with Synex leads to the probability of a higher rigidity in vivo. Due to the distractability of Synex, a better intervertebral compression was achieved. Therefore, an additional tightening of the posterior fixator after insertion of Synex was not necessary, in contrast to the Harms cage.

A patellar dislocation is usually understood to mean a lateral dislocation of the patella. Medial patellar dislocations have mainly been described after surgical treatment, such as release of the lateral retinaculum. Here a case of medial patellar dislocation is reported which did not occur subsequent to surgery. Wilberg-III patella, genu recurvatum with patella alta and a m. vastus medialis insertion widely distal to the patella were predisposing factors.

The objective was to evaluate mid-term results after arthroscopic subacromial decompression (ASD) with special focus on the bias due to an application to social insurance for pension based on sickness disability. The study group consisted of 42 patients (28 male, 14 female). ASD was performed in 1993 or 1994 for impingement stage II. ⋯ The Constant score improved from 49.6 +/- 18.5 to 84.8 +/- 14.3. The subgroup of patients having applied to social insurance for pension had significantly worse results compared with the remaining patients: VAS: 4.9 +/- 3.1 vs. 7.5 +/- 3.1; Constant-Score: 76.1 +/- 12.7 vs. 88.3 +/- 13.5. The fact that patients try to get benefit from social insurance based on sickness disability significantly biased the outcome after ASD.
