Surgical reconstruction of deformed Charcot feet carries high risk of non-union, metalwork failure and deformity recurrence. The primary aim of this study was to identify the factors contributing to these complications following hindfoot Charcot reconstructions. We retrospectively analysed patients who underwent hindfoot Charcot reconstruction with an intramedullary nail between 2007 and 2019 in our unit. Patient demographics, co-morbidities, weightbearing status and post-operative complications were noted. Metalwork breakage, non-union, deformity recurrence, concurrent midfoot reconstruction and the measurements related to intramedullary nail were also recorded.Introduction
Methods
An additional pathology should be considered for Achillodynia differentials – the intratendinous tear (ITT) – for which we describe symptoms, ultrasound findings and co-presenting pathology. Examinations of 740 Achillodynic patients in one specialist centre were reviewed. ITTs were defined as a clearly visualised echopoor area situated centrally and extending to, but not through the tendon periphery, with pain on palpation and no clinical findings consistent with Achilles rupture. Descriptive statistics were used to analyse differences between pathological sub-groups, and images described qualitatively.Introduction
Materials and Methods
High-volume image guided injections (HVIGI) followed by structured rehabilitation have been shown to be effective in various musculoskeletal conditions including Achilles tendinopathy and shoulder impingement syndrome. The aim was to explore the effect of a HVIGI in Hoffa's fat pad impingement, a common cause of anterior knee pain. 100 consecutive subjects who received a HVIGI followed by a standardised physiotherapy rehabilitation regime for Hoffa's fat pad impingement (diagnosed using clinical history, examination and magnetic resonance imaging) at one specialist MSK centre were sent a follow-up questionnaire. The questionnaire collected demographics, symptom length and the percentage improvement in symptoms following the HVIGI. All had received HVIGI consisting of 10ml of 0.5% Marcaine and 50mg of hydrocortisone followed by a structured rehabilitation programme with a focus on lower limb alignment control, flexibility, hip and knee strengthening in line with best practice. Data was analysed using SPSS version 20 at this interim stage; data collection is continuing.Introduction
Materials and Methods
Epidural steroid injections can provide temporary relief of symptoms in the treatment of lumbar spinal stenosis. Surgery is indicated when conservative measures fail. We hypothesise that patients who gain temporary relief of symptoms from the administration of epidural steroid injections are more likely to result in an improvement in symptoms following surgical intervention compared to patients who do not respond to injection therapy. The records of patients who had received both an epidural injection and surgical intervention for lumbar spinal stenosis between July 2008 and July 2010 were identified and retrospectively reviewed. Relief of symptoms following epidural injection was noted at 6 weeks post procedure and the patients symptoms following surgical intervention was noted and classified according to MacNab's criteria at 3 months post-surgery.Background
Method
Autologous bone grafts are considered gold standard in the repair of bone defects. However they are limited in supply and are associated with donor site morbidity. This has led to the development of synthetic bone graft substitute (BGS) materials, many of which have been reported as being osteoinductive. The structure of the BGS is important and bone formation has been observed in scaffolds with a macroporous morphology. Smaller pores termed ‘strut porosity’ may also be important for osteoinduction. The aim of this study was to compare the osteoinductive ability of one silicate-substituted calcium phosphate (SiCaP) with differing strut porosities in an ectopic ovine model. Our hypothesis was that SiCaP with greater strut porosity would be more osteoinductive. The osteoinduction of SiCaP BGS with two different strut porosities (AF and AF++) was investigated. The materials had an identical chemical composition and morphological structure but differing strut porosity (AF=22.5%, AF++=47%). Implants were inserted into the paraspinal muscles in skeletally mature sheep. Procedures were carried out in compliance with UK Home Office regulations. There were 12 implants in each group. Implants remained in vivo for 8 and 12 weeks and on retrieval were prepared for undecalcified histology. Sections were stained and examined using light microscopy. A line intersection method was used to quantify bone, implant and implant surface/bone contact within seven random regions of interest along each implant. A Mann-Whitney U test was used for statistical analysis where p values < 0.05 were considered significant.INTRODUCTION
