Abstract. Objective. To investigate the safety and cost-effectiveness of interscalene brachial plexus block/regional anaesthesia (ISB-RA) in patients undergoing reverse total shoulder replacement. Methods. This retrospective study included 15 patients with symptomatic rotator cuff arthropathy who underwent reverse total shoulder arthroplasty (rTSA) under ISB-RA without general anaesthesia in the beach chair position from 2010 to 2018. The mean patient age was 77 years (range 59–82 years). Patients had associated medical comorbidities: American Society of Anesthesiologists (ASA) grade 2–4. Assessed parameters were: duration of anaesthesia, intra-operative systolic blood pressure variation, sedation and vasopressor use, duration of post-operative recovery, recovery scores, length of stay, and complications. A robust cost analysis was also performed. Results. The mean (range) duration of anaesthesia was 38.66 (20–60) min. Maximum and minimum intra-operative systolic blood pressure ranges were 130–210 and 75–145 mmHg, respectively (mean [range] drop, 74.13 [33–125] mmHg). Mean (range) propofol dose was 1.74 (1–3.0) mg/kg/h. The Median (interquartile range) post-operative recovery time was 30 (20–50) min. The mean (range) postoperative recovery score (local scale, range 5–28 where lower values are superior) was 5.2 (5–8). The mean (range) length of stay was 8 (1–20 days); the two included patients with ASA grade 2 were both discharged within 24 hours. One patient with predisposing history developed pneumonia; however, there were no complications related to ISB-RA. The mean (range) cost per patient was £101.36 (£59.80-£132.20). Conclusions. Our data demonstrate that rTSA under ISB-RA is safe, cost-effective and a potentially viable alternative for patients with multiple comorbidities. Notably, patients with ASA grade 2 who underwent rTSA under ISB-RA had a reduced length of stay and were discharged within 24 hours

Introduction. Aged trauma patients with proximal femur fractures are prone to various complications. They may be associated with their comorbidities which also need to be adressed. These complications limit the patient”s postoperative health status and subsequently their activity and independency. As an attempt to improve the postoperative management of aged hip fracture patients a better understanding of the postoperative condition in these patients is necessary. Therefore, this meta-analysis is intended to provide an overview of postoperative complications in the elderly hip fracture patients and to improve the understanding of an adequate postoperative management. Material and method. Medline was used to screen for studies reporting on the complication rates of hip fracture patients > 65 years. The search criteria were: “proximal femur fracture, elderly, complication”. In addition to surgical studies, internal medicine and geriatric studies were also included. Randomized studies, retrospective studies as well as observation studies were included. Furthermore, reoperation rates as well as treatment-related complications were recorded. The 1-year mortality was calculated as outcome parameter. Results. Overall 54 studies were enrolled, published between 2011 and 2016. The mean age of the 9812 patients was 81 years (65–99 years). Follow-up was at least one year. The reoperation rate after osteosynthesis of pertrochanteric femur fractures was 8.7%. The reoperation rate was dependent on the type of fracture and the surgical method. Pneumonia (9,5%) and urinary tract infections (27%) were the most common postoperative infections. With 23%, delirium was one of the most common medical complications. The 1-year mortality rate was 18.7%. Conclusion. Orthogeriatric patients represent a complex patient population. Addressing the special needs of elderly patients reduces postoperative complications. Establishing comanagement or orthogeriatric wards can also be helpful to manage comorbidities and postoperative complications. It is important to not only choose the proper surgical procedure but to monitor orthogeriatric patients closely during their hospitalization

Contrary to NICE guidance there remains a role for Austin-Moore hemiarthroplasty (AM) for patients with significant pre-existing comorbidities who are at higher risk of death and complications following cemented hemiarthroplasty. We analysed prospectively-collected data comparing uncemented AM hemiarthroplasty in frail, poorly-mobile patients, and cemented hemiarthroplasty. We analysed age, pre-operative morbidity, duration of operation, death rate and complication rate. AM patients were significantly older with significantly higher ASA grades. It took significantly longer to optimise them before surgery. AM was significantly shorter to perform. There was no significant difference in complications requiring re-operation. Twice as many AM patients developed post-operative pneumonia despite absence of cement. Twice as many AM patients died after surgery and a significant proportion died within the first month despite no increased risk of repeat operation, shorter operating time and no risk of cement-disease. We infer that these patients would likely have fared badly had they undergone a longer, cemented procedure. A modern cemented prosthesis costs £691 more than AM. There exists a subset of patients within the neck of femur cohort who are significantly more unwell. Contrary to guidelines, we suggest that the cheaper, user-friendly Austin-Moore can be a reasonable prosthesis to use for this cohort

Abstract. In aged trauma patients the basic prerequisite is early mobilization and full weight-bearing, as immobilization can trigger various complications such as pressure ulcers, pneumonia, urinary tract infections and others. Mortality of elderly patients increases significantly in fracture patients with partial weight-bearing compared to populations with total weight-bearing. Besides the limited physical strength in these patients, partial-weight bearing is however frequently used for the aftercare of hip fracture patients. Therefore, the present study aims to evaluate mobility of aged hip fracture patients with regards to weight-bearing and postoperative mobility. Methods. An insole mobile force sensor was used to measure the post-operative weight-bearing by assessing the compressive forces between foot and shoe. Only patients (n=15) that suffered a trochanteric fracture >75 years of age were included and compared to a study group of patients (n=18) with fractures of the lower limb <40 years of age. Patients with cognitive disorders such as delirium and other diseases limiting the realization of partial weight-bearing were excluded. Both groups were instructed to maintain partial weight bearing of the affected limb following surgery. Following five days of training by our department of physiotherapy, the patients were requested to perform a gait analysis with the insole mobile force sensor. During gait analysis the maximum load was measured (kg) and the time over which the partial load could be maintained was determined. Results. None of the aged patients in the test group could meet the partial load at all times. 73.33% of patients (11 out of 15) exceeded the specified load by more than twice (> 40 kg). In the control group, 55.56% (10 of 18) of the patients were able to meet the partial load. A further 22.22% of the young patients (4 out of 18) were able to exceed only slightly (<120%, <24 kg). It was also shown that only 11.11% (2 of 18) put more than double of the allowed weight (> 40 kg) on the affected leg in the younger group. Only one of the aged patients was able to exceed the pre-determined weight-bearing restrictions for less than 10% of the measured time. In comparison, significantly more patients in the control group (88,89%; 16 of 18; p<0,05) were able to maintain the partial load for more than 90.0% of the time of gait analysis. Conclusion. Elderly patients seem to be unable to follow partial weight-bearing restrictions as proven in the present trial. As early mobilization of geriatric trauma patients is an important element for a successful rehabilitation, the relict of postoperative partial weight-bearing in these patients should be abandoned. Thus, the surgical therapy should allow immediate full weight bearing following surgery of aged hip fracture patients

Systemic factors are believed to be pivotal for the development of heterotopic ossification in severely-injured patients. In this study, cell cultures of putative target cells (human fibroblastic cells, osteoblastic cells (MG-63), and bone-marrow stromal cells (hBM)) were incubated with serum from ten consecutive polytraumatised patients taken from post-traumatic day 1 to day 21 and with serum from 12 healthy control subjects.

The serum from the polytraumatised patients significantly stimulated the proliferation of fibroblasts, MG-63 and of hBM cells. The activity of alkaline phosphatase in MG-63 and hBM cells was significantly decreased when exposed to the serum of the severely-injured patient. After three weeks in 3D cell cultures, matrix production and osteogenic gene expression of hBM cells were equal in the patient and control groups. However, the serum from the polytraumatised patients significantly decreased apoptosis of hBM cells compared with the control serum (4.3% vs 19.1%, p = 0.031).

Increased proliferation of osteoblastic cells and reduced apoptosis of osteoprogenitors may be responsible for increased osteogenesis in severely-injured patients.
