Background
The reverse total shoulder arthroplasty (RTSA) is a common therapy for the fracture sequelae (FS) of the proximal humerus. The aim of this study was to show the short and midterm clinical outcome of the RTSA for FS and to identify prognostic factors.Methods
Data from 46 patients with chronic FS who underwent RTSA were analysed. The clinical follow-up included the Constant score and radiographic examination. Patients were divided into groups based on the Boileau classification of FS, and the degree of metaphyseal bone loss was measured (Boileau type I 9 patients; type II 3 patients; type III 8 patients and type IV 16 patients). Scapular notching was assessed according to the classification of Sirveaux.Results
The mean postoperative Constant score was 57. Clinical outcomes were similar among the various FS groups, as defined according to the Boileau classification, but patients who had undergone revision arthroplasty had a significantly inferior mean Constant score than patients with type IV FS. There were no significant differences between patients who were initially managed with conservative therapy and those treated surgically. Patients with metaphyseal bone loss >3 cm showed inferior clinical scores. Inferior scapular notching was seen in 25 patients, and had a negative effect on the clinical outcome. Complications included five infections and one dislocation.Conclusion
Metaphyseal bone loss was unfavourable prognostic factors in patients with FS treated with RTSA. However, the Boileau classification did not serve as a prognostic criterion. Previous operative or conservative treatment had no influence on the outcome and scapular notching was associated with inferior clinical results. 相似文献3.

Background
For the treatment of hallux valgus commonly distal metatarsal osteotomies are performed. Persistent problems due to the hardware and the necessity of hardware removal has led to the development of absorbable implants. To overcome the limitations of formerly used materials for biodegradable implants, recently magnesium has been introduced as a novel implant material. This is the first study showing mid-term clinical and radiological (MRI) data after using magnesium implants for fixation of distal metatarsal osteotomies.Material and methods
26 patients with symptomatic hallux valgus were included in the study. They were randomly selected to be treated with a magnesium or standard titanium screw for fixation of a modified distal metatarsal osteotomy. The patients had a standardized clinical follow up and MRI investigation 3 years' post-surgery. The clinical tests included the range of motion of the MTP 1, the AOFAS, FAAM and SF-36 scores. Further on the pain was evaluated on a VAS.Results
Eight patients of the magnesium group and 6 of the titanium group had a full clinical and MRI follow up 3 years postoperatively. One patient was lost to follow-up. All other patients could be interviewed, but denied full study participation. There was a significant improvement for all tested clinical scores (AOFAS, SF-36, FAAM, Pain-NRS) from pre-to postoperative investigation, but no statistically relevant difference between the groups. Magnesium implants showed significantly less artifacts in the MRI, no implant related cysts were found and the implant was under degradation three years postoperatively.Conclusion
In this study, bioabsorbable magnesium implants showed comparable clinical results to titanium standard implants 3 years after distal modified metatarsal osteotomy and were more suitable for radiologic analysis.Level of evidence

Despite preventive methods, lymphoceles frequently form following kidney transplantation (KTx), with an incidence of 0.6%–51%. Here, we summarize the current strategies for preventing and managing this complication, and describe the approach used in our department. Rapid diagnosis and early treatment of lymphoceles through a well-defined approach can prevent or reduce the risk of organ loss. Diagnosis can be made by ultrasound, computed tomography, or magnetic resonance imaging and laparoscopic fenestration is the current therapy of choice when non-surgical methods fail. Preventive methods should be performed pre-, intra-, and post-operatively. A peritoneal fenestration at the end of KTx seems to be a reasonable method for preventing lymphocele formation. 相似文献

Background
Evidence related to the effectiveness of combination drug therapy for the treatment of osteoporosis is currently considered insufficient. Therefore, this study was performed to clarify the effects of monotherapy, and combination therapy, with a bisphosphonate (minodronic acid hydrate), a bone resorption inhibitor, and calcitonin (elcatonin), which is effective for the alleviation of pain due to vertebral fractures in osteoporotic patients.Methods
Study participants comprised of 51 female subjects with post-menopausal osteoporosis, whose main complaint was acute lower back pain caused by vertebral fractures. Subjects were randomly allocated into three groups and then administered with either intramuscular injections of elcatonin at a dose of 20 units weekly, minodronic acid hydrate at a dose of 1 mg daily, or a combination of these two drugs. As primary endpoints, time-dependent changes in levels of pain were assessed using a visual analog scale from baseline to 6 months of duration. In addition, we examined the effects of monotherapies, and a combination therapy on bone resorption, with changes in bone mineral density at 4 sites and advanced hip assessment parameters from baseline to 6 months. A two-tailed significance level of 5% was used for hypothesis testing.Results
Elcatonin monotherapy showed some alleviation of pain immediately after any vertebral fractures, which was more than in the minodronic acid hydrate monotherapy group. In addition, the minodronic acid hydrate monotherapy group experienced more effective inhibited bone resorption than the elcatonin monotherapy group. In the combination therapy, the efficacy for alleviating pain and inhibiting bone resorption was equivalent to the effect observed in the elcatonin and minodronic acid hydrate monotherapy groups respectively, with further improved values of bone mineral density observed in the femoral neck and lumbar vertebrae, and in parameters of advanced hip assessment compared with both monotherapy groups.Conclusions
Combination therapy with elcatonin and minodronic acid hydrate appears to be an effective treatment for osteoporosis patients with lower back pain, caused by fresh vertebral fractures. 相似文献14.

Ex vivo lung perfusion (EVLP) is currently used for both standard and extended‐criteria donor (ECD) lungs. To enlarge the donor pool, we might have to extend the threshold for ECD donation. The purpose of this study was to estimate how many additional ECD lungs could be recruited by EVLP. We reviewed all multi‐organ donors (MODs) from our collaborative donor hospitals (January 2010–June 2015). All unused lung donors were categorized using registered donor data and evaluated by two independent investigators to identify which lungs could be transplanted after EVLP. 584 MODs were registered at our transplant center. 268 (45.9%) were declined as lung donor at the moment of registration, and 316 (54.1%) were considered as a donor for lung transplantation. In the latter, lungs from 220 (37.7%) donors were transplanted and 96 donors (16.4%) were not. We identified 78 of 364 declined donors (21.4%) whose lungs could potentially become transplantable after EVLP. With this retrospective database analysis of unused lung donors, we identified a large potential for EVLP to further increase the donor pool in transplant centers where the majority of donor lungs are already extended. 相似文献
