Introduction

Traditionally correction of idiopathic paediatric scoliosis is done by hybrid fixation. This involves a judicious combination of mono-axial and poly-axial screw constructs. This has inherent perceived advantages with better deformity correction and maintaining alignment without loss of correction over time.

Study design

Single centre retrospective review of prospective collected data on the radiological analysis of idiopathic paediatric scoliosis corrections. The study compared hybrid screw constructs (poly-axial & mono-axial) to all poly-axial screw constructs over 28 months.

Aim

Spondylodiscitis and vertebral osteomyelitis can lead to long-term sequelae if not diagnosed and treated promptly and appropriately. The Royal National Orthopaedic Hospital (RNOH) has devised a new spinal infection referral system within the UK that allows cases to be discussed in a specialist multi-disciplinary (MDT) forum. National guidelines were devised in 2013 to help guide treatment, which recommends both tissue biopsies from the affected region and a MRI of the entire spine. The aims of this study were to assess the current treatment and referral practices and compare them with the set guidelines. It is hypothesised that a high percentage of patients are started on antibiotics without a biopsy or a positive set of blood cultures, a low percentage of patients are referred without undergoing a MRI of the full spine and that there is a long delay in referral to the MDT.

Method

A retrospective case study analysis was carried out on all spinal infection referrals received by the Royal National Orthopaedic Hospital over a 2-year period (2014–16), using the standards set by the current national guidelines. Clinical features, haematology results, imaging, biopsy results, treatment and outcome were all reviewed. Three key areas were addressed; whether antibiotics were commenced before positive cultures or biopsy, whether a MRI of the entire spine was performed and the time taken for referral from the onset of symptoms.

Many operations have been recommended to treat Pars Interarticularis fractures that have separated and are persistently symptomatic, but little other than conservative treatment has been recommended for symptomatic incomplete fractures.

10 consecutive patients aged 15–28 [mean 21.7 years] were treated operatively between 2010–2014. All but one were either professional athletes [3 cricketers, 2 athletics, 1 soccer] or academy cricketers [3 patients]. 8 patients had unilateral fractures, and two had bilateral fractures at the same level. The duration of pre-operative pain and disability with exercise ranged from 4–24 months [mean 15.4 months].

The operation consists of a percutaneous compression screw inserted through a 1.5cm midline skin incision under fluoroscopic guidance: 6 cases were also checked with the O-arm intra-operatively. Post-operation the patients were mobilised with a simple corset and discharged the following day with a customised rehabilitation program.

All 12 fractures in 10 patients healed as demonstrated on post-operative CT scans at between 3–6 months. One patient had the screw revised at 24 hours for an asymptomatic breach, and one patient developed a halo around the fracture site without screw loosening, and had a successful revision operation to remove the screw and graft the pars from the screw channel. All patients achieved a full return to asymptomatic activity, within a timescale of 4–12 months post-surgery, depending on the sport.

Athletes that have persistent symptoms from incomplete pars interarticularis fractures should consider percutaneous fixation rather than undergoing prolonged or repeated periods of rest.

Introduction:

Several reports showed superior fusion rates, as high as 100%, using rhBMP-2 with ALIF cages. This has led to the widespread off-label use of rhBMP-2 in several other lumbar fusion procedures. There is paucity of reports analysing the clinic-radiological outcome of using rhBMP-2 to promote bone union in cases of symptomatic pseudoarthosis following lumbar spine fusion.

Methods:

52 consecutive patients who underwent revision spinal surgery for symptomatic pseudoarthosis utilizing rhBMP-2 between 2008 and 2013 were included in the study. Demographic, and surgical data were collected from medical records. Functional outcomes were recorded using the ODI. All patients had preoperative fine-cut CT scan to confirm pseudoarthosis. Postoperative CT-scan at 6 months was routinely done to confirm fusion.
