Vertebral body tethering (VBT) is a non-fusion technique to correct scoliosis allowing correction of scoliosis through growth modulation (GM) by tethering the convex side to allow concave unrestricted growth similar to the hemiepiphysiodesis concept. The other modality is anterior scoliosis correction (ASC) where the tether is able to perform most of the correction immediately where limited growth is expected. A retrospective analysis of 20 patients (M:F=19:1 – 9–17 years) between January 2014 to December 2016 with a mean five-year follow-up (4 to 7).Abstract
Aims
Methods
Sling immobilization of the upper limb may affect balance. Computerized dynamic posturography (CDP) provides a validated, objective assessment of balance control and postural stability under dynamic test conditions. We tested the balance of individuals with a shoulder stabilization sling (SSS) using an Equitest Machine to objectively assess imbalance wearing a sling. 42 right hand dominant (RHD) adults (16 females, 26 males; average age 22; range 20–35 years) were included in the study. 6 controls and two SSS groups with 18 Dominant Hand (DH) and 18 Non Dominant Hand (NDH). CDP assessed balance by Sensory Organization Test (SOT), Motor Control Test (MCT) and Adaptation Test (ADT).Introduction
Methods
Hip fractures pose a significant burden on the healthcare system. Hyperglycaemia and a state of Type 2 diabetes exists post operatively. Being normoglycaemic has well documented benefits. Pre operative carbohydrate loading has been shown to have two good effects. It decrease hyperglycaemia post operatively and allows the patient to undergo less strict fasting protocols. Insulin resistance to date has not been examined in these patients and this was determined using a validated formula (HOMA/IR). Three trauma hospitals were enrolled and patients with hip fractures requiring operative fixation were enlisted. Exclusion criteria: diabetic patients and inability to imbibe. 100 neck of femur fractures were examined. 46 patients were fasted normally. 32 test patients were given a carbohydrate rich drink pre operatively the night before surgery and in the morning up to 2 hours prior to surgery. 22 patients were excluded. Serum random glucose and insulin levels were taken on admission. Fasting serum glucose and insulin levels were taken on day one post operatively.Aims
Methods
Fracture neck of femur (NOF) is a significant morbidity in the elderly patient and a significant burden on the healthcare system. Surgery induces a stress response resulting in hyperglycaemia, insulin resistance, and glucose intolerance (Diabetic triad). Furthermore, fasting pre operatively establishes a catabolic state. This diabetic state can last up to 3 weeks following surgery and therefore could be associated with the morbidity of diabetes. 26 patients with fracture NOF were enrolled in this preliminary study. Exclusion criteria included diabetics. Each underwent hemiarthroplasty or Dynamic Hip Screw fixation. Pre and post operative serum glucose levels were taken. 15 patients were selected to have pre and post operative serum insulin levels because of the expensive nature of the test. Normal glucose range = 4-6 mmol/l. Normal insulin range = 17.8 – 173 pmol/l. 21 of 26 patients exhibited post operative hyperglycaemia (range 5 - 16.4mmol/l). 7 of 15 patients tested for insulin remained in our pilot study where pre and post insulin levels were obtained. Insulin is a technically difficult level to take and samples are easily discarded. 6 of 7 Insulin levels showed marked elevation post operatively (range 17.5 – 595.8).Methods
Results
We aimed to assess whether using long stem femoral components, with cemented distal fixation and proximal impaction grafting allows early patient mobilisation, reconstitution of the proximal femur and long term stability of fixation in patients with aseptic loosening and proximal femoral analysis. Over the past ten years 239 patients have been treated with an Elite Plus cemented long stem femoral implant, 33% with concomitant proximal impaction bone grafting. Many of the patients had co-morbidities. The average age at revision was 72 years (range 48 to 91). There was a slight female predominance. Fourteen percent of hips had been previously revised. Forty-eight patients were deceased and 22 were not available for follow-up; this left a cohort of 169 patients who were available for radiological and questionnaire review at an average of 4.5 years. According to the Paprosky grading for pre-operative bone loss 40% had moderate to severe bone loss (grade IIIb or IV). The Barrack grading was used to assess the cement mantle post-operatively with 65% showing good cementation. The Harris and O'Neill grades were used at final review to assess probability of loosening with only 8% being probably or definitely loose. The average Oxford Hip Score was 29. Mesh ± cables were required in a third of cases to allow adequate containment and pressurisation. It was generally felt that the long stem needed to be at least one third longer than the initial component. The re-revision rate was 1.2 with a 10 year survivorship analysis of 94%. The complication rate of almost 6% included periprosthetic fractures, dislocations, infection and mesh breakage. A long stem cemented femoral implant can be useful in bypassing proximal femoral deficiency in the appropriate patient.
