Background. Fractured neck of femurs cause substantial morbidity and mortality in elderly patients and represent a huge financial burden to the NHS. Hip fracture patients are generally malnourished on admission, often having poor nutritional inpatient intake, hindering recovery and increasing chances of “unfavourable outcome.” Nutritional care is included in intercollegiate guidelines for management of fractured neck of femur patients, but is nutrition a management priority in clinical practice?. Study Aim. To evaluate protein and energy intake of acute fractured neck of femur patients depending on admission MMSE, and compare these to department of health targets. Method. 40 acute fractured neck of femur admissions were recruited between December 08-March 09 and put into three groups depending on admission MMSE. Initial nutrition screening information (mid-arm circumference, grip strength, MUST score) was recorded and through food charts daily kcal and protein intake were calculated for a three day period. Results. 100% of patients recruited were high risk of malnutrition on admission. Overall average daily calorie intake over 3 days was 385.9 kCal, average protein intake was 14.1g. Intake for each group was well below recommended target intake of 1810kCal and 46.5g, p<0.05. Discussion. On admission all 40 patients included were classified high risk for malnutrition, therefore in need of dietetic and nutritional intervention. Two patients received dietician input and oral supplementation. Recorded nutritional intake was very low, well below target nutrient intakes for this population even before extra requirement due to the stress response is accounted for. Whilst there is a paucity of hard evidence linking poor nutrition to clinical outcome, this is likely to be detrimental to rehabilitation from surgery. Conclusion. Despite attempted adherence to NICE nutrition guidance, involving screening tools, care plans and protected mealtimes; acutely unwell, malnourished patients are not receiving their basic nutritional requirements

Bone infection occurring after fractures or orthopedic surgery can progress to the chronic stage and lead to poor results of treatment. Optimal treatment of chronic osteomyelitis are stabilization the fracture, biological recovery of bone defects and destroy bacterial infection. Traditional methods of treatment are systemic administration of antibiotics and surgical treatment of active infection focus. Systemic antibiotics are part of the standard therapy after surgical treatment of infected bone, but their effectiveness is limited due to malnutrition and low absorption at the site of infection. Moreover, long-term treatment and higher doses are associated with serious side effects. The aim of this investigation was to study the results of the complex treatment of patients with chronic osteomyelitis using biodegradable nanomaterials “PerOssal” as antibiotic delivery system. The study was performed at Regional center traumatology and orthopedics, Karaganda, Kazakhstan. A total 20 patient with post-traumatic/post-operative osteomyelitis were included in this open-label, prospective study. Bacteriological examination was taken with the determination of culture and sensitivity test preoperatively, during and postoperatively. After radical surgical debridement and ultrasound cavitation, the bone cavity was full filled with Perosal which can be loaded with different antibiotics depending from the antibiotic sensitivity test. Postoperative wound is completely was sutured. Systemic antibiotic treatment are allowed. The course of infection was monitored by determination leukocyte count and blood sedimentation rate; blood samples were taken befor, 24 hours after surgery, and on days 3, 7, 10, 14. Wound healing was assessed on days 2, 3, 7, 10, and at the time of removal of sutures. Resorption of implanted beads and bone reconstruction were evaluated by X-ray at after operation and at approximately one, three and six months after implantation. A total of 20 patients (mean age 38,1 (26 to 53), 14 male, 6 female) were treated with Perossal pellets (AAP, Germany) from October 2013 to April 2015. Mean leukocyte counts and blood sedimentation rate were within the normal laboratory range and did not indicate infectious complications during the first 21 days after surgery. Primary wound healing occurred in 18 patients and secondary wound healing in two patients. There were two cases of re-infection during the course of the study, one of them related to an incomplete eradication of infected tissue and multidrug-resistant strain occurring during the course of the study, the other is occurred that patient non-compliance. Radiographic analysis six months after surgery showed progressive resorption of the implanted pellets, but only 10 cases have decreasing size of defects on X-ray. This study in adult patients with chronic post-traumatic/post-operative osteomyelitis demonstrated that these biodegradable bone filler pellets which can be loaded with different antibiotics are a clinically useful local antibiotic delivery system and bone substitute which can be used as an alternative to other anti-infective implants. The implantation of the pellets was safety and well tolerated in all patients. This composite can provide adequate protection against bacterial infection during the first weeks after implantation and to support the bone healing process

Objectives

The aim of this study was to investigate the effect of hyperglycaemia on oxidative stress markers and inflammatory and matrix gene expression within tendons of normal and diabetic rats and to give insights into the processes involved in tendinopathy.

This review is aimed at clinicians appraising preclinical trauma studies and researchers investigating compromised bone healing or novel treatments for fractures. It categorises the clinical scenarios of poor healing of fractures and attempts to match them with the appropriate animal models in the literature.

We performed an extensive literature search of animal models of long bone fracture repair/nonunion and grouped the resulting studies according to the clinical scenario they were attempting to reflect; we then scrutinised them for their reliability and accuracy in reproducing that clinical scenario.

Models for normal fracture repair (primary and secondary), delayed union, nonunion (atrophic and hypertrophic), segmental defects and fractures at risk of impaired healing were identified. Their accuracy in reflecting the clinical scenario ranged greatly and the reliability of reproducing the scenario ranged from 100% to 40%.

It is vital to know the limitations and success of each model when considering its application.
