Randomized Controlled Trial Comparative Study
[The influence of a controlled active motion splint on proprioception after anterior cruciate ligament plasty. A prospective randomized study].
A ruptured anterior cruciate ligament (ACL) leads to both mechanical and functional instability. Functional instability is caused by proprioceptive deficit. The aim of this study was to determine whether the proprioceptive deficit can be reduced by using a controlled active motion (CAM) splint postoperatively. ⋯ Using a CAM splint in addition to physiotherapy after ACL plasty in comparison to physiotherapy alone decreases the proprioceptive deficit significantly. We recommend the use of a CAM splint in the postoperative management following ACL plasty.

Comparative Study
[Surgically treated intraarticular fractures of the trapeziometacarpal joint -- a clinical and radiological outcome study].
Fractures of the thumb metacarpal occur quite frequently at the base. Intra-articular metacarpal base fractures (such as Bennett or Rolando fractures) present treatment challenges and surgical therapy remains controversial. Malunion of these fractures may lead to the development of painful osteoarthrosis at the trapeziometacarpal joint which can seriously impair overall hand function. ⋯ Exact anatomical restoration of the articular surface may not be essential for obtaining satisfactory functional results.

Comparative Study Clinical Trial
[Clinical experience with the Siremobil Iso-C(3D) imaging system in pelvic surgery].
In pelvic and acetabular surgery intraoperative control of reduction and implant position is sometimes hard to achieve with conventional C-arm technology. The Siemens C-arm Iso-C(3D) imaging system enables axial cuts and two- or three-dimensional reconstructions to be generated. Following the good experience in surgery of the spine and extremities, its clinical applicability in pelvic surgery was evaluated in 30 patients in a prospective clinical trial. ⋯ One revision was indicated, and one avoided. However, in spite of its advantages in pelvic surgery, handling, sterile covering and data transfer need to be improved. For bilateral pelvic injuries the image size is too small.

The Morel-Lavallée lesion is a rare condition that was first described by the French physician Maurice Morel-Lavallée in 1853. The lesion is caused by forces of pressure and shear stress at the borders of subcutaneous tissue to the muscle fascia or bone as they are seen in run-over accidents. It leads to a shear of skin and subcutaneous tissue from the neighboring fascia followed by the development of a blood-filled hollow space at predestined regions of the body. ⋯ The history and the impressive clinical findings are demonstrated as well as the differential operative therapy performed, partially with osteosynthesis of accompanying bone injuries. According to the recommendations of the literature known to us, an adjusted therapeutic regime suited to the particular findings was carried out and in all three cases uncomplicated healing can be reported. Our results are in line with the existing recommendations, which are to relieve the soft tissue hematoma in time and sufficiently, and secondly to carry out débridements initially as well as planned second-look operations.
