RESUMEN
Modern radial head prostheses have recently become more common in the treatment of comminuted radial head fractures. The goal of this study was to evaluate how well the EVOLVE® modular metallic radial head implant prosthetic restores the functional range of motion and stability of the elbow. 30 patients with comminuted radial head fractures received an arthroplasty with an EVOLVE® prosthesis in our institution. 20 of those patients were available for long-term follow-up (mean > 10 years). The outcomes were assessed on the basis of pain, motion, and strength. The overall outcome was scored with functional rating scores. According to the Broberg-Morrey elbow evaluation score, after a mean follow-up period of 10.2 years, ten (50.0%) patients were rated as very good, four (20.0%) as good, six (30.0%) as satisfactory, and none as poor. In the long-term results the Broberg-Morrey score increased from 79 (in short-term results) to 89 points. The Disabilities of the Arm, Shoulder, and Hand (DASH) outcome measure questionnaire showed an average of 16.2 points. Initially, patients had an extension deficit of 20°, which was reduced to 5° at the latest follow-up. In our long-term results, an improvement in the function of the elbow was observed after arthroplasty using a metallic modular radial head implant. Comminuted radial head fractures with elbow instability can be treated effectively with the EVOLVE® radial head prosthesis, which restores stability in acute treatment. Our long-term results after 10.2 years demonstrate good functional outcome and low major complication rate. IV.

The societies of western countries are facing enormous economic and social challenges. Despite a declining population size the number of elderly patients is growing and will lead to an increase in cases of trauma in the near future. In addition, the health care system will have to be financed by a reduced labor force. To realize the ambitious political goal of providing comprehensive medical care an economization of hospital treatment must be achieved. The bottleneck within the surgical specialties in case of efficient scheduling will be the capacity utilization of the operating theatres. Additional separate outpatient operating theatres adjacent to hospitals could be an efficient instrument for using resources and economizing medical procedures. Considering the socio-demographic alterations of our society an adequate discussion regarding the general medical conditions is essential.

Arthrodesis of the elbow joint (EA) is a rare salvage procedure which is disliked by both surgeons and patients. The aim of this study was to analyze the indications, the operation techniques and the outcome of EA in patients treated at our clinic. Between January 1997 and December 2005 a total of 20 patients with a mean age of 55 years (range 27-85 years) were treated with EA at our clinic. In 18 patients a compression plate was used as surgical technique. In 18 out of the 20 patients the operation was performed post-traumatically after infection, bone and tissue defects and painful loss of motion. Of these patients, 16 could be followed up for an average time of 66 months. The outcome was evaluated based on the degree of pain, range of motion, radiographic findings and grip strength measured with the Jamar dynamometer. All patients had a solid and fused EA, the average angle was 89 degrees (range 80-110 degrees) and the grip strength was reduced by 27% compared to the unaffected side. The patients achieved 56 points in the Morrey score, 38.29 points in the DASH (disabilities of the arm, shoulder and hand) score and 80 points in the Constant-Murley score. The indication of EA depends on several factors, therefore it is essential to take the patients' functional requirements into consideration and the best arthrodesis angle should be validated pre-operatively. In these cases the patients can regain good grip strength and a high level of stability within defined functional limitations.

BACKGROUND: The German DRG (diagnosis-related groups) system has changed since the inauguration in 2005, whereby written inquiries and on-site auditing have been carried out by the medical inspection service for health insurance companies (MDK). Modifications in the G-DRG system are reflected in changes in the MDK visitations. This article describes exactly how these examinations have changed over time. In order to achieve this all auditing reports were evaluated. RESULTS: In the beginning correct coding and documentation were the most interesting items for the health insurance fund inspectors. Nowadays, length of in-patient treatment and specific points relating to current changes in the G-DRG system are being questioned. All areas of the hospital have now been examined during this period. There was no change in the loss resulting from the regular examinations over the years. However, the effort and input of manpower are extremely high. CONCLUSIONS: To cope with the changes in the German DRG system hospitals have to be flexible. The experiences with the regular MDK visitations can positively influence hospital organizational structures.

METHODS: Between 2005 and 2012, 50 patients (23 female, 27 male) with nonunion of the humeral shaft were included in this retrospective study. The mean age was 51.3 years (14 to 88). The patients had a mean of 1.5 prior operations (sd 1.2;1 to 8). All patients were assessed according to a specific risk score in order to devise an optimal and individual therapy plan consistent with the Diamond Concept. In 32 cases (64%), a change in the osteosynthesis to an angular stable locking compression plate was performed. According to the individual risk an additional bone graft and/or bone morphogenetic protein-7 (BMP-7) were applied. RESULTS: A successful consolidation of the nonunion was observed in 37 cases (80.4%) with a median healing time of six months (IQR 6). Younger patients showed significantly better consolidation. Four patients were lost to follow-up. Revision was necessary in a total of eight (16%) cases. In the initial treatment, intramedullary nailing was most common. DISCUSSION: The use of locking compression plates in combination with autologous cancellous bone graft has been shown to be a safe and effective treatment. In more complex cases, the use of the Masquelet technique and BMP-7 may be indicated at the first revision operation. TAKE HOME MESSAGE: Our results suggest the Diamond Concept is a successful treatment strategy for nonunions of the humeral shaft.

BACKGROUND: Fractures of the subcapital and proximal humerus shaft region are common fractures of the human skeleton. Their treatment should provide an early functional after-care of the shoulder joint, that is prone to arthrofibrosis. Although the upper extremity is not weight-bearing the occurrence of proximal humerus non-unions leads to severe impairment with inability to work and restrictions of activity of daily life. The aim of this study was to investigate whether an operative revision of proximal humerus non-unions with reosteosynthesis and application of distant autologous bone grafts can lead to sufficient bone healing. The second aim was to find out whether patients achieved an acceptable functional outcome, as alternatively patients could be treated by reconstruction with a shoulder prosthesis. PATIENTS AND METHODS: 27 patients (female = 15, male = 12) with reosteosynthesis of the proximal humerus and proximal humeral shaft due to non-union after initially operative fracture treatment were included between 2008 and 2014. Average age of patients was 56 years (23-87), 48% had no comorbidities, while 52% of the patients had at least 1 comorbidity such as diabetes, hypertension or nicotine abusus. The mean number of prior surgical intervention was 1.2 (1-3). The mean time between initial surgery and re-osteosynthesis was 12.3 months. Patients with signs of infection pseudarthrosis were excluded. The initial type of osteosynthesis was with plates (n = 16; thereof PHILOS Plate n = 14), and intramedullary nails (T2, Targon Nail, PHN, Seidel Nail; n = 11). Revision surgery was done with plate osteosynthesis (n = 26; thereof PHILOS Plate n = 4; LC Plate n = 10; angle plate n = 12). In 23 patients (89%) a distant bone transplantation was done from the iliac crest, and 1 patient received allogenous bone. Three patients (11%) received bone morphogenetic protein 7 (BMP 7) in combination with distant bone graft. Intraoperative swabs from the pseudarthrosis area showed no bacterial pathogen after 14 days of incubation. DASH score and Constant score were used to evaluate the functional outcome after revision surgery. Bone healing was determined by standard X-rays and evaluated by a modified radiological score. RESULTS: 89% of the patients could be followed for an average of 28 months and the radiological follow-up was at 9 months. The radiological score showed very good (50%), or good results, and a sufficient bone healing was shown in 25 of 27 patients (93%). The pseudarthrosis revision surgery failed in two cases (n = 1 persisting non-union; n = 1 humeral head necrosis after re-operation with angle plate). DASH scores provided a mean of 40 ± 28.8 with a range from 0-97 points, and the results from the Constant score provided 45 ± 25.4. The analysis with variation of age showed a trend for better results in female patients < 60 years of age. As complications after bone graft 3 patients had persistent local dysesthesia (11%), in one case fracture of the iliac bone occurred that healed with conservative treatment. CONCLUSION: The pseudarthrosis revision surgery with humeral head preserving re-osteosynthesis with bone transplantation is an effective treatment for non-unions of the proximal humerus and the proximal humeral shaft and the current results showed high bone consolidation rates. As the functional results remained limited after revision an individual treatment decision should be made concerning the most appropriate therapy. While a shoulder prosthesis may be considered in the aged patient, a revision strategy with reosteosynthesis should be considered particularly in younger patients.

BACKGROUND: For many years, resection was the only therapy used for comminuted fractures of the radial head. When associated with an injury of the collateral ligament, the outcome was often unsatisfactory. Implantation of the modern radial head prosthesis promises a better outcome. METHODS: Between June 2001 and January 2005, 30 patients were treated with a modular metallic radial head arthroplasty; 28 patients were available for follow-up. Their mean age was 49 years. The patients were followed for an average of 29 months. The outcomes were assessed on the basis of pain, motion, radiographic findings, and grip strength as measured with the Jamar Dynamometer. The overall outcome was rated using a pain visual analog scale, and the scoring systems described by Radin and Riseborough and by Broberg and Morrey. RESULTS: 19 patients achieved excellent or good results, 8 had fair results, and 1 had a poor result as based on the Morrey score. 22 patients showed periprosthetic osteolysis on radiologic examination. CONCLUSION: Arthroplasty with a modular metallic radial head combined with ligament reconstruction is an effective alternative to radial head resection. Compared with resection, the results using the EVOLVE prosthesis demonstrate definite advantages with regard to clinical outcome.
