Trust compliance with best practice tariff criteria for total hip and knee replacement.

BACKGROUND: Satisfaction of the best practice tariff criteria for primary hip and knee replacement enables on average an additional £560 of reimbursement per case. The Getting it Right First Time report highlighted poor awareness of these criteria among orthopaedic departments. METHODS: The authors investigated the reasons for non-compliance with the best practice tariff criteria at their trust and implemented a quality improvement approach to ensure successful adherence to the standards (a minimum National Joint Registry compliance rate of 85%, a National Joint Registry unknown consent rate below 15%, a patient-reported outcome measure participation rate of ≥50%, and an average health gain not significantly below the national average). This was investigated using quarterly online reports from the National Joint Registry and NHS Digital. RESULTS: Initially, the trust had a 31% patient-reported outcome measures participation rate arising from a systematic error in the submission of preoperative patient-reported outcome measure scores. Re-audit following the resubmission of patient-reported outcome measure data under the trust's correct organization data service code confirmed an improvement in patient-reported outcome measure compliance to 90% and satisfaction of all criteria resulting in over £450 000 of additional reimbursement to the trust. CONCLUSIONS: The authors would urge others to review their compliance with these four best practice tariff criteria to ensure that they too are not missing out on this significant reimbursement sum.

Sciatic nerve neuritis of no cause in primary total hip replacement: A case series.

Neuritis of the sciatic nerve is a rare complication of total hip replacements. It is characterized by symptoms of neuropathic pain with or without motor and or sensory symptoms. Causes include direct intra-operative trauma or mechanical lengthening of the nerve. Cases of sciatic nerve neuritis without an organic cause however, are rarer still. We present two cases of sciatic nerve neuritis post total hip replacement with no identified organic cause. Whereas the reversal of the underlying cause has shown improvement in symptoms, in cases without an organic cause our experience advocates close observation and conservative management with spontaneous resolution of symptoms.

3D-printed Patient-specific Guides for Hip Arthroplasty.

Surgeons and engineers constantly search for methods to improve the surgical positioning of implants used for joint arthroplasty. Rapid prototyping is being used to develop patient-specific instrumentation (PSI) and has already been successfully translated into large-scale clinical use for knee arthroplasty. PSI has been used in shoulder arthroplasty; however, it is not yet known whether PSI provides improved accuracy and outcomes compared with conventional methods in either shoulder arthroplasty or knee arthroplasty. In the hip, PSI has been limited to the positioning of custom-manufactured implants and a small number of surgeons testing the emerging solutions from different manufacturers. Early results indicate consistent accurate positioning of implants with the use of PSI in hip arthroplasty but with added costs and uncertain effect on clinical outcomes.

The Introduction of a Multidisciplinary Hip Fracture Pathway to Optimise Patient Care and Reduce Mortality: A Prospective Audit of 161 Patients.

INTRODUCTION: Hip fractures are a major cause of morbidity and mortality in the elderly. A new patient pathway was introduced in our institution to facilitate rapid preoperative assessment, acute physician involvement and early surgery for patients with hip fractures. We sought to assess its impact on patient care and outcomes. MATERIALS AND METHODS: Prospective audit of 161 patients admitted with a proximal femoral fracture in the six months before (92 patients) and after (69 patients) implementation of the pathway. Data included: time to orthogeriatric assessment (TtG); time to surgery (TtS); length of hospital stay (LOS); return to original accommodation; inpatient mortality rate. RESULTS: In the six months after introduction of the pathway, there was an increase in patients who received pre-operative medical assessment (85% after vs. 19% before, p=0.0001). Average TtG decreased (19 vs. 91 hours, p=0.0001), as did LOS (19.5 vs. 24.8 days, p=0.029) and mortality (4 vs. 14%, p=0.0336). There was an increase in patients returning to their original place of accommodation (80% vs. 57%, p=0.0069). There was a reduction in mean TtS (31 vs. 37 hours, p=0.0663), although this was not statistically significant. DISCUSSION AND CONCLUSIONS: Rapid medical optimisation and prompt surgery significantly improve outcomes in patients with hip fractures. By involving an acute medical team in patient care from the point of admission, we have significantly improved our inpatient mortality and increased the proportion of patients returning to their preoperative place of accommodation, thereby maintaining patient independence and reducing the financial and logistical burden on social care.

Sacral insufficiency fractures: an underdiagnosed injury during childbirth? : A case report and review of literature.

UNLABELLED: Insufficiency fractures during pregnancy or childbirth are difficult to diagnose but holds high morbidity for a vulnerable patient group. In documenting the patient's pathway, diagnostic challenges and treatment options, it is hoped that pregnancy-related insufficiency fractures will be better diagnosed and treated. INTRODUCTION: Sacral insufficiency fractures are a poorly understood phenomenon, which poses diagnostic and therapeutic challenges. Peripartum females who suffer from transient osteoporosis of pregnancy have been shown in several reports to be at particular high risk of these fractures. METHOD: This case report details such a case and highlights some of the challenges that this condition presents. Furthermore, it draws on the current literature to offer options for improved techniques for diagnosis and up-to-date management for future practice.

Time- and concentration-dependent effects of dissolution products of 58S sol-gel bioactive glass on proliferation and differentiation of murine and human osteoblasts.

Bone loss is a significant clinical problem, and treatments utilizing donated graft material are limited. To meet future demands in the healthcare industry, there has been a shift of outlook toward the use of bioactive materials for tissue regeneration. A number of in vivo and in vitro studies have highlighted the potential of the bioactive glass ceramic 45S5 Bioglass as a synthetic regenerative scaffold. The application of sol-gel processing techniques has led to the synthesis of mesoporous bioactive glasses with greater textural and compositional variety. In this study, we evaluated the effects of supplemented tissue culture medium containing up to 203 ppm silica prepared by static soaking of particles of 58S sol-gel bioactive glass (58% SiO(2), 33% CaO, 9% P(2)O(5)) on the in vitro proliferation and differentiation of murine and human primary osteoblasts. These extracts had a higher silica content than those used previously in studies of 45S5 Bioglass, because of the faster rates of ion exchange permitted by the higher surface area-to-volume ratio of mesoporous glass. We found that osteoblasts from both species increased their proliferation in response to the glass-conditioned medium. In addition, the extent to which supplemented medium could alter cell differentiation varied with time in culture. Proliferation induced by supplemented medium paralleled effects induced by treatment with basic fibroblast growth factor, a known mitogenic growth factor for osteoblasts. Bone nodule formation was also increased by exposure to the glass-conditioned medium and this effect was positively correlated with the dose of glass used to prepare the medium. Apoptosis was stimulated by glass-conditioned medium in murine osteoblasts, but inhibited in human osteoblasts. These data demonstrate the bioactive effects of dissolution products derived from sol-gel materials on primary osteoblasts and complements in vivo studies that indicate the suitability of this material as a bone graft substitute.
