Abstract
BACKGROUND AND HYPOTHESIS The aim of this study was to address the inconsistency regarding the operative treatment of Rockwood type III acromioclavicular joint separation. We compared results after single- and double TightRope® reduction with results after acromioclavicular transfixation via K-wires only and additional ligament augmentation in acute acromioclavicular (AC) joint separations graded Rockwood type III, and hypothesized that the TightRope® technique leads to better clinical and radiological results. MATERIALS AND METHODS We conducted a retrospective clinical cohort study and included 42 consecutive patients (mean age 43 years [24-66]) diagnosed and operatively treated between 2004 and 2012 (mean follow-up was 54.6 months [15-118]). Specific shoulder scores as well as scores reflecting the patients' overall mental and physical health status were used. Radiological evaluation was also performed. RESULTS The SF12 test revealed comparability between all subgroups. Specific shoulder tests and a visual analogue scale demonstrated comparable results. Radiographic measurements showed a significant reduction in the AC distance and CC distance after surgery in all subgroups. The early complication rate was 9.5% for all patients, while late complications occurred in 14.3% of all cases. CONCLUSIONS Compared to the established methods, the operative TightRope® procedures represent a safe alternative in Rockwood III injuries. All investigated techniques predominantly led to good and excellent clinical results in acute Rockwood type III AC joint instabilities. Avoidance of material removal and shorter hospital stays appear to speak in favour for the TightRope® technique. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE Stable fixation of distal humerus fracture fragments is necessary for adequate healing and maintenance of reduction. The purpose of this study was to measure the reliability and accuracy of interpretation of postoperative radiographs to predict which implants will loosen or break after operative treatment of bicolumnar distal humerus fractures. We also addressed agreement among surgeons regarding which fracture fixation will loosen or break and the influence of years in independent practice, location of practice, and so forth. METHODS A total of 232 orthopedic residents and surgeons from around the world evaluated 24 anteroposterior and lateral radiographs of distal humerus fractures on a Web-based platform to predict which implants would loosen or break. Agreement among observers was measured using the multi-rater kappa measure. RESULTS The sensitivity of prediction of failure of fixation of distal humerus fracture on radiographs was 63%, specificity was 53%, positive predictive value was 36%, the negative predictive value was 78%, and accuracy was 56%. There was fair interobserver agreement (κ = 0.27) regarding predictions of failure of fixation of distal humerus fracture on radiographs. Interobserver variability did not change when assessed for the various subgroups. CONCLUSIONS When experienced and skilled surgeons perform fixation of type C distal humerus fracture, the immediate postoperative radiograph is not predictive of fixation failure. Reoperation based on the probability of failure might not be advisable. TYPE OF STUDY/LEVEL OF EVIDENCE Diagnostic III.

Abstract
The most frequent causes of chronic instability of the pubic symphysis are sports-related continual overload and traumatic symphyseal injuries. Acute injury of the pubic symphysis may be the result of external forces acting on the anterior pelvic ring or the result of internal forces, such as those arising during parturition. The postpartum form of instability following a complication-free birth is reversible and usually returns to normal within a few months through strengthening of the pelvic floor muscles. Residual instability of the pubis symphysis is on the whole a rare complication. Although established therapy options for acute symphyseal separation can be found in the literature, there are only a few case reports on chronic symphyseal instability. There are no guidelines on standardized therapy options. This review article examines the etiology, clinical findings, diagnostic techniques and management options for patients suffering from chronic symphyseal instability.

Abstract
BACKGROUND AND AIMS Treatment of scapular neck fractures remains controversial. Advantages of surgical treatments, such as anatomical restoration of fracture displacement, are counterbalanced by approach morbidity. We conducted a meta-analysis of 463 scapular neck fractures and compared clinical, functional, and radiographical outcomes in operatively and nonoperatively treated scapular neck fractures. MATERIAL AND METHODS A literature search was conducted, including the databases PubMed/MEDLINE, Embase, and the Cochrane Database of Systematic Reviews. Manuscripts were included if they reported a precise description of treatment, complications, functional outcomes, and/or radiographic evaluation. Data about day-to-day activities, level of pain-freeness, range of motion, functional grading, and radiographical assessment were pooled and compared using fixed effects models. RESULTS AND CONCLUSIONS A total of 22 manuscripts were relevant, including 1 prospective cohort study and 21 retrospective studies. The studies showed a high heterogeneity in the result assessment. Most patients had concomitant injuries. In total, 234 out of the 463 fractures were treated operatively. Pain-freeness and radiographic outcome measurements were significantly better in the operatively treated group, whereas range of motion was significantly improved in the nonoperative treated patients. Complication rate for surgical treatment was about 10%. From the achievable data, there was no bias detected when comparing the two treatment groups. However, those data could not be analyzed for all included studies. For the same reason, the role of additional surgical treatment for concomitant injuries to the shoulder girdle could not be cleared completely. Caution should be exercised, and individual injury patterns have to be taken into consideration when considering the best treatment options.

Abstract
PURPOSE To compare outcome after total hip arthroplasty (THA) through the mini-incision approach versus the standard transgluteal approach. METHODS 80 women and 63 men aged 33 to 89 (mean, 62) years with primary osteoarthritis of the hip were randomised to undergo unilateral THA through a mini-incision approach (Micro-hip, n=55) or standard, lateral, transgluteal approach (Bauer, n=88). Levels of haemoglobin, haematocrit, serum creatine kinase, and C-reactive protein, length of hospital stay, mobilisation, and any complication were recorded. Visual analogue scale (VAS) for pain was assessed. Hip function was assessed using the Harris Hip Score and the Oxford Hip Score, whereas general health was assessed using the EQ-5D general health questionnaire. The cup inclination and varus/valgus of the stem position were measured using a goniometer. RESULTS The Micro-hip group achieved a significantly lower mean incision length (9.3 vs. 13.4 cm, p<0.001), mean surgical time (60 vs. 68 minutes, p=0.021), mean reduction in haemoglobin level (2.1 vs. 2.8 g/dl, p<0.001), and mean VAS for pain from hour 6 to day 6 (all p<0.05). One patient in the Micro-hip group developed early aseptic loosening of the cup and underwent revision surgery at month 4. Three patients in the Bauer group and one patient in the Micro-hip group sustained intra-operative nondisplaced fractures of the proximal femur, which were fixed with cerclages. Two patients in the Microhip group developed deep vein thrombosis during week 1. CONCLUSION THA through the Micro-hip approach achieved faster pain relief.

Abstract
BACKGROUND The treatment of patients with mild head injury is related to a continuous lack of finances. The current investigation summarises radiological costs of patients from a level I trauma centre and discusses the indication for CT scanning within the G-DRG system. MATERIAL AND METHODS The study includes all patients who underwent a CCT scan in 2011. Diagnosis, length of stay and cost data were recorded for every patient. Finally, frequent diagnosis groups were summarised to clusters (Basis-DRG/MDC 21A). RESULTS A total of 380 patients was treated. Within the largest group (G-DRG B80Z) the costs for a CCT already took up one quarter of the total proceedings. In combination with the high cost for monitoring patients with mild head injuries this causes an ongoing lack of finances. CONCLUSION In spite of the often necessary CCT investigation in mild head injuries, the earnings do not cover the costs of the patients. To improve the situation clear guidelines for CCT scanning should be provided and the reimbursement in particular in the diagnosis group of the G-DRG B80Z has to be improved.

Abstract
OBJECTIVE Bankart and Hill-Sachs lesions are often associated with anterior shoulder dislocation. The MRI technique is sensitive in diagnosing both injuries. The aim of this study was to investigate Bankart and Hill-Sachs lesions with MRI to determine the correlation in occurrence and defect sizes of these lesions. METHODS Between 2006 and 2013, 446 patients were diagnosed with an anterior shoulder dislocation and 105 of these patients were eligible for inclusion in the study. All patients were examined using MRI. Bankart lesions were classified as cartilaginous or bony lesions. Hill-Sachs lesions were graded I-III using a modified Calandra classification. RESULTS The co-occurrence of injuries was high [odds ratio (OR) = 11.47; 95% confidence interval (CI) = 3.60-36.52; p < 0.001]. Patients older than 29 years more often presented with a bilateral injury (OR = 16.29; 95% CI = 2.71-97.73; p = 0.002). A correlation between a Bankart lesion and the grade of a Hill-Sachs lesion was found (ρ = 0.34; 95% CI = 0.16-0.49; p < 0.001). Bankart lesions co-occurred more often with large Hill-Sachs lesions (O = 1.24; 95% CI = 1.02-1.52; p = 0.033). CONCLUSION If either lesion is diagnosed, the patient is 11 times more likely to have suffered the associated injury. The size of a Hill-Sachs lesion determines the co-occurrence of cartilaginous or bony Bankart lesions. Age plays a role in determining the type of Bankart lesion as well as the co-occurrence of Bankart and Hill-Sachs lesions. ADVANCES IN KNOWLEDGE This study is the first to demonstrate the use of high-quality MRI in a reasonably large sample of patients, a positive correlation of Bankart and Hill-Sachs lesions in anterior shoulder dislocations and an association between the defect sizes.

Abstract
Injuries of the hamstring muscle complex (HMC) often affect athletes participating in specific sporting activities. Mild injuries that constitute a mere strain of the muscle can be managed symptomatically, while severe injuries often require surgical intervention to precipitate a return to function. Neglected injuries usually result in a long-term functional impairment. Therefore, surgical reconstruction of the HMC is advised for both partial and complete lesions. Without acute repair, a chronic lesion referred to as hamstring syndrome can result due to dysfunction of the HMC. Surgical intervention is usually recommended. A case of a chronic severe partial injury to the HMC managed conservatively in a 49-year old female is presented to illustrate the level of function that can be achieved after non-operative management. The clinical and radiological findings are presented 18 months post-injury along with a review of the current literature. There are no previous reports in the literature describing this scenario. This case indicates the need for re-evaluation in treatment options in partial hamstring muscle ruptures. A surgical treatment of partial rupture should be considered more often as an adequate treatment option and cofactors that influence the prognosis must be revealed. The indication of surgical intervention should be re-evaluated within the first months in case of conservative treatment.

Abstract
We report the functional and socioeconomic long-term outcome of patients with pelvic ring injuries. We identified 109 patients treated at a Level I trauma centre between 1973 and 1990 with multiple blunt orthopaedic injuries including an injury to the pelvic ring, with an Injury Severity Score (ISS) of ≥ 16. These patients were invited for clinical review at a minimum of ten years after the initial injury, at which point functional results, general health scores and socioeconomic factors were assessed. In all 33 isolated anterior (group A), 33 isolated posterior (group P) and 43 combined anterior/posterior pelvic ring injuries (group A/P) were included. The mean age of the patients at injury was 28.8 years (5 to 55) and the mean ISS was 22.7 (16 to 44). At review the mean Short-Form 12 physical component score for the A/P group was 38.71 (22.12 to 56.56) and the mean Hannover Score for Polytrauma Outcome subjective score was 67.27 (12.48 to 147.42), being significantly worse compared with the other two groups (p = 0.004 and p = 0.024, respectively). A total of 42 patients (39%) had a limp and 12 (11%) required crutches. Car or public transport usage was restricted in 16 patients (15%). Overall patients in groups P and A/P had a worse outcome. The long-term outcome of patients with posterior or combined anterior/posterior pelvic ring injuries is poorer than of those with an isolated anterior injury.

Abstract
Chronic osteomyelitis is a severe complication characterized by soft tissue and bone pathogenic infection resulting in osseous destruction. Surgical management is demanding and poses a challenge in achieving the goals of treatment, which are control of infection, bone healing as well as satisfactory functional outcome. Therapeutic strategies are based on a combined application of radical surgery and systemic antibiotic therapy. The bony defects which remain after extensive debridement have to be reconstructed with bone grafting after soft tissue coverage and the healing process is decisive for a successful outcome.

Abstract
PURPOSE The incidence of gunshot wounds from civilian firearms is increasing. Despite this fact, guidelines on indications for bullet removal are scarce. In this analysis, we combine an overview of the available literature in these rare entities with our experiences in our own clinical practices. METHODS We conducted a systematic literature search of computerized bibliographic databases (Medline, EMBASE, and the Cochrane Central Register). The local experience of the authors was reviewed in light of the available literature. RESULTS 145 full-text articles were suitable for further evaluation. Only six retrospective studies were available, and no prospective study could be retrieved. Most of the articles were case reports. In the South African co-author's own clinical practice, approximately 800 patients are treated per year with gunshot wounds. CONCLUSIONS In summary, there are only a few clear indications for bullet removal. These include bullets found in joints, CSF, or the globe of the eye. Fragments leading to impingement on a nerve or a nerve root, and bullets lying within the lumen of a vessel, resulting in a risk of ischemia or embolization, should be removed. Rare indications are lead poisoning caused by a fragment, and removal that is required for a medico-legal examination. In all other cases the indication should be critically reviewed.

Abstract
Human mesenchymal stem cells are a valuable cell source for tissue engineering. Determination of cell number and viability is crucial. However, this can be tested only at the end of cell culture. This study shows that Resazurin dye staining is a reliable tool for evaluation of cell number and viability in culture without cell perturbation.

Abstract
The quality of care of seriously injured persons in Germany is nationally and internationally recognized to be at a high level. However, there are local discrepancies. In 2006 the German Association of Trauma Surgery published the White Paper for the Management of the Seriously Injured. The goal of the paper is a further increase in the quality of care of seriously injured persons. A crucial point of the publication is the call to establish regional trauma networks in Germany. Work on this project has been carried out in eastern Bavaria since spring 2007. The first meeting of the Trauma Network of eastern Bavaria took place in July 2007. On 3rd September 2008 the university hospital of Regensburg was the first clinic audited in Germany. To date nearly 75% of all hospitals in the trauma network of eastern Bavaria have been audited. The establishment of a regional trauma network is a multifactorial event. Essential factors in the development of the trauma network were found to be the communication between the head physicians and the nomination of an appointee of the regional trauma network. For the head physicians the 9 meetings of the trauma network since July 2007 functioned as the communication platform. These exchanges of the head physicians are necessary to animate a trauma network. The appointee of the regional trauma network--most suitably a member of staff of the speaker of the trauma network--is essential to guarantee communication between meetings and to manage prompt responses to questions from the network. This article describes the experiences gained during the implementation of the trauma network in eastern Bavaria.
