Quantification of dynamic posterior translation in modified bilateral Alexander views and correlation with clinical and radiological parameters in patients with acute acromioclavicular joint instability.
Classification of AC-joint instability is based on radiologic evaluation of anteroposterior (a.p.) stress views of both shoulders, neglecting the horizontal component of instability. Recent studies have proposed an association of dynamic posterior translation (DPT) and inferior clinical results. The purpose of this study was to quantify DPT in modified Alexander views and correlate it with other radiological and clinical data. ⋯ Measuring the OLAC is a convenient way for quantifying DPT in modified Alexander views. It showed significant correlation with clinical scores, indicating the relevance of DPT in patients with AC-joint injury.

Radiographic outcomes of single versus dual plate fixation of acute mid-shaft clavicle fractures.
The clavicle exhibits considerable movement in three planes making rigid fixation challenging. The addition of a second plate may be considered to improve fixation rigidity, but risks compromising the blood supply to the fracture site. The purpose of this study is to assess if extraperiosteal dual plate fixation increases the rate of non-union, reoperation, and complications at 1 year for surgically treated acute mid-shaft clavicle fractures. ⋯ This limited series of patients demonstrates dual plate fixation is a reliable option for acute mid-shaft clavicle fractures, with excellent union rates and low complication rates. Compared to single plate fixation, no significant differences in outcomes were identified. In the case of more complex fracture patterns, application of a second extraperiosteal plate may be utilized without compromising healing or increasing complication rates.

The frequency of cartilage lesions in non-injured knees with symptomatic meniscus tears: results from an arthroscopic and NIR- (near-infrared) spectroscopic investigation.
Are symptomatic tear injuries to the menisci of the knee frequently or always associated with cartilage damage to the corresponding articular surfaces and other joint surfaces, respectively? ⋯ Through our investigations, a high, if not complete, concomitance of degenerative cartilage lesions and degenerative meniscus damage was demonstrated. From this it can be concluded that the entity of "isolated degenerative meniscus damage" clearly does not exist in practice. It is therefore highly probable that degenerative meniscus lesions, as a part of general joint degeneration, are to be interpreted in the context of the development of arthrosis. The practical consequences still are unclear. Patients after partial meniscectomy need a longer follow-up to detect potential cartilage lesions as well as an OA progression.

The extent of environmental and body contamination through aerosols by hydro-surgical debridement in the lumbar spine.
Surgical site infections occur in 1-6% of spinal surgeries. Effective treatment includes early diagnosis, parenteral antibiotics and early surgical debridement of the wound surface. ⋯ The study showed that during hydro-surgery debridement, contaminated aerosols spread over the whole surgical room and contaminate the theatre and all personnel.

Suprapectoral biceps tenodesis using a suture plate: clinical results after 2 years.
Several techniques for performing a tenodesis of the long head of biceps (LHB) are described. Only few outcome studies are published. This note describes a unicortical fixation via a suture plate-comparable to a distal biceps refixation-performed arthroscopically or mini-open via standard suprapectoral approach. The aim of this study is to show the clinical outcome after 6, 12, and 24 months. ⋯ Tenodesis of the LHB with a unicortical suture plate is a safe fixation technique with good-to-excellent clinical results after a minimum follow-up of 2 years. Long-term follow-up is needed.
