Newman SD, Lotfibakhshaiesh N, O'Donnell M, et al., 2014, Enhanced Osseous Implant Fixation with Strontium-Substituted Bioactive Glass Coating, TISSUE ENGINEERING PART A, Vol: 20, Pages: 1850-1857, ISSN: 1937-3341
The use of endosseous implants is firmly established in skeletal reconstructive surgery, with rapid and permanent fixation of prostheses being a highly desirable feature. Implant coatings composed of hydroxyapatite (HA) have become the standard and have been used with some success in prolonging the time to revision surgery, but aseptic loosening remains a significant issue. The development of a new generation of more biologically active coatings is a promising approach for tackling this problem. Bioactive glasses are an ideal candidate material due to the osteostimulative properties of their dissolution products. However, to date, they have not been formulated with stability to devitrification or thermal expansion coefficients (TECs) that are suitable for stable coating onto metal implants while still retaining their bioactive properties. Here, we present a strontium-substituted bioactive glass (SrBG) implant coating which has been designed to encourage peri-implant bone formation and with a TEC similar to that of HA. The coating can be successfully applied to roughened Ti6Al4V and after implantation into the distal femur and proximal tibia of twenty-seven New Zealand White rabbits for 6, 12, or 24 weeks, it produced no adverse tissue reaction. The glass dissolved over a 6 week period, stimulating enhanced peri-implant bone formation compared with matched HA coated implants in the contralateral limb. Furthermore, superior mechanical fixation was evident in the SrBG group after 24 weeks of implantation. We propose that this coating has the potential to enhance implant fixation in a variety of orthopedic reconstructive surgery applications.

Sethi K, Newman SDS, Bhattacharya R, 2012, An unusual case of bipolar segmental clavicle fracture., Orthop Rev (Pavia), Vol: 4
Segmental clavicle fractures are uncommon injuries. When they do present, they tend to comprise a distal and mid-shaft fracture. A clavicular injury with proximal and distal fractures is a rarer presentation still which is sparsely covered in the literature. These injuries, which have been termed bipolar, are easily missed at presentation and due to their infrequency the optimal method of management for these patients is unclear. We describe the successful non-operative management of a bipolar clavicle fracture and review the existing literature.

Kundra RK, Newman S, Saithna A, et al., 2010, Absorbable or non-absorbable sutures? A prospective, randomised evaluation of aesthetic outcomes in patients undergoing elective day-case hand and wrist surgery, The Annals of The Royal College of Surgeons of England, Vol: 92, Pages: 665-667, ISSN: 0035-8843
<jats:sec><jats:title>INTRODUCTION</jats:title><jats:p> We prospectively evaluated aesthetic outcomes in a group of randomised patients who underwent elective day-case hand and wrist surgery using either absorbable or non-absorbable sutures. </jats:p></jats:sec><jats:sec><jats:title>PATIENTS AND METHODS</jats:title><jats:p> A cohort of 100 adult patients were randomised using sealed envelopes to receive either absorbable or non-absorbable sutures for their wound closure. Clinical review was carried out at 6 weeks. A postal questionnaire was sent to all patients 3 months following surgery comprising a visual analogue scale (VAS) for wound satisfaction, a validated 6-point patient scar assessment tool and the shortened version of the disabilities of the arm, shoulder and hand questionnaire (QuickDASH). </jats:p></jats:sec><jats:sec><jats:title>RESULTS</jats:title><jats:p> From the postal questionnaire, 70 responses were received. There was no statistically significant difference between the two groups in terms of VAS, patient scar assessment tool and quick DASH. </jats:p></jats:sec><jats:sec><jats:title>CONCLUSIONS</jats:title><jats:p> For elective day-case hand and wrist surgery, either suture material can be used confidently with respect to overall aesthetic appearance in such patients. </jats:p></jats:sec>
