AB  - To describe our centre's results, experience and technical points learnt with the 
      SKy Bone Expander System for osteoporotic vertebral compression fractures (VCFs). 
      Forty consecutive patients with painful single level T12 or L1 osteoporotic VCF 
      who had failed conservative management for more than 3 months had 40 single level 
      SKy Bone Expander kyphoplasties performed. Using local anaesthesia with patients 
      in a prone, hyper-lordotic position, a unilateral, percutaneous, intra-pedicular 
      approach was employed. Once correctly positioned, the SKy Bone Expander was 
      expanded, creating a void. It was subsequently contracted, removed and bone 
      cement injected. Pre-kyphoplasty and 12-month post-kyphoplasty radiological and 
      functional outcomes were recorded. Statistical analysis was by Wilcoxon Signed 
      Ranks Test. Median percentage increase in anterior, middle and posterior 
      vertebral body heights at 12-month post-operative was 51.25% [inter-quartile 
      range (IQR) 17.21-93.22], 52.29% (IQR 26.50-126.17) and 9.84% (IQR 4.94-19.26) 
      respectively, while median percentage decrease in kyphotic angle was 30.77% (IQR 
      17.06-46.61). There was no significant vertebral body correction loss at 12-month 
      post-operative. Visual analogue score, North American Spine Society and Short 
      Form-36 scores for physical functioning and bodily pain scores improved by 
      medians of 5.0 (IQR 3.0-8.0), 1.45 (IQR 0.68-2.90), 20.5 (IQR 0.0-40.8) and 10.0 
      (IQR 0.0-20.0) respectively. All P-values were <0.001. There were eight 
      adjacent/remote level VCFs, three cases of cement extravasation and one case of 
      the SKy Bone Expander being unable to be contracted and withdrawn from the 
      vertebral body. It was left in situ. This is the first reported incidence of such 
      a complication. The SKy Bone Expander System appears to be a viable alternative 
      to balloon tamp kyphoplasty. Important technical considerations include proper 
      device positioning within the vertebral body before expansion, single use of 
      devices, familiarity with salvage procedure and injection of bone cement under 
      close image intensifier guidance to prevent cement extravasation.
