ABSTRACT
PURPOSE: The purpose of this study was to evaluate the intermediate-term clinical and radiological outcomes for acute, unstable acromioclavicular joint (ACJ) injuries treated with the arthroscopically assisted BiPOD stabilisation technique. METHODS: Twenty-three patients who sustained acute, unstable ACJ injuries were included in this prospective study. We recorded demographics, injury classification, time to surgery, clinical scores, radiological outcomes and complications; each patient completed a minimum of 2 years post-operative observation. RESULTS: Mean follow-up was 26 months (range, 24-34). Clinical outcomes scores demonstrated good 2-year results: relative Constant score, 97.9/100; ACJ Index, 89.4/100; Subjective Shoulder Value, 92.4/100 and Taft = 11.1/12. Final C-C distance showed a mean of 0.7 mm (SD ± 1.8 mm) at 2 years. Complication rate was 9%. CONCLUSION: The BiPOD technique shows excellent, reliable intermediate-term results with a favourable complication rate compared to existing techniques; it provides a comprehensive surgical option for the stabilisation of acute ACJ injuries restoring both vertical and horizontal stability.

Traumatic dislocation of the shoulder - a guide for medical practicioners Abstract. Traumatic dislocation of the shoulder joint is a common injury. Young patients suffer from dislocations usually during leisure and competitive activities, the elderly are prone for injuries because of falls. We provide an overview about state-of-the-art management in first traumatic shoulder dislocations. Besides an overview for mechanisms leading to injuries, we describe first line therapy as well as techniques to reposition the shoulder. First time traumatic glenohumeral dislocations can usually be treated without surgery, we elucidate the topic regarding the need for further imaging as well as possible injuries accompanying the dislocation.

BACKGROUND: Early femoral stem subsidence following a cementless THA is correlated with aseptic loosening of the femoral component. The short femoral stems allow bone sparing and implantation through a minimally invasive approach; however, due to their metaphyseal anchoring, they might demonstrate different subsidence pattern than the conventional stems. METHODS: In this prospective single-center study, a total of 68 consecutive patients with an average age of 63 years, and a minimum follow-up of 5 years following a cementless THA with a metaphyseal-anchored short femoral stem were included. The femoral stem subsidence was evaluated using "Ein Bild Roentgen Analyse" (EBRA). RESULTS: Average stem migration was 0.96 +/- 0.76 mm at 3 months, 1.71 +/- 1.26 mm at 24 months, and 2.04+/- 1.42 mm at last follow-up 60 months postoperative. The only factor that affected migration was a stem size of 6 or more (r2 = 5.74; p = 0.039). Subdivision analysis revealed, that only in females migration appeared to be affected by stem size irrespective of weight but not in men (female stem size of 6 or more vs. less (Difference = - 1.48 mm, R2 = 37.5; p = 0.001). Migration did not have an impact on clinical outcome measures. CONCLUSIONS: The examined metaphyseal-anchored short femoral stem showed the highest subsidence within the first 3 months postoperative, the implant began to stabilize at about 24 months but continued to slowly migrate with average total subsidence of 2.04 mm at 5 years following the THA. The amount of stem subsidence was not associated with worse clinical outcomes such as HHS, patient satisfaction, or pain.
