Study Design: Case series OBJECTIVE.: The aim of this study was to assess the patient-reported outcome measures (PROMs) and patient satisfaction of multilevel lumbar total disc arthroplasty (TDA) for symptomatic multilevel degenerative disc disease (MLDDD).

Summary Of Background Data: TDA has been shown to be safe and effective for the treatment of symptomatic single level degenerative disc disease.

Background: Analysis was performed of two patient cohorts who underwent fixation without fusion for unstable thoracolumbar and lumbar fractures: (I) minimally invasive surgery (MIS) group using combined monoaxial-polyaxial pedicle screws inserted percutaneously; (II) open surgery (OS) group using Schanz screw constructs. Our aim was to compare radiographic and clinical indices of the 'gold standard' of open Schanz screw to MIS monoaxial-polyaxial screw constructs.

Methods: There were 13 patients in the MIS group and 19 in the OS group.

Background: Treatment options for aortic-iliac pathology may include endovascular repair and open surgical repair. Treatment options for degenerative disc disease (DDD) are varied but commonly include anterior reconstruction. When both the aortic-iliac and spinal pathologies are significant and surgical intervention is indicated for each pathology, the opportunity exists for concurrent treatment of both the aortic-iliac pathology and DDD in the same operation.

Study Design: Prospective cohort study.

Objectives: To evaluate the role of magnetic resonance imaging (MRI) in evaluation of fusion status following anterior lumbar interbody fusion (ALIF) and compare agreement and confidence in assessing fusion or its absence on MRI to the current standard computed tomography (CT).

Methods: A prospective follow up of patients undergoing surgery by 2 spine surgeons between 2012 and 2015 at a single institution.

Purpose: To investigate whether pre-operative magnetic resonance imaging (MRI) of the lumbar multifidus muscle (LMM) would predict clinical outcomes following lumbar spinal decompression for symptomatic spinal stenosis.

Methods: A prospective cohort of patients with symptomatic neurogenic claudication, documented spinal stenosis on pre-operative MRI underwent spinal decompression. All subjects completed standardised outcome measures (Core Outcome Measures Index (COMI), Oswestry Disability Index (ODI v2.

Background: Our aim was to determine whether patients derived benefit from removal of pedicle screw instrumentation for axial pain without other cause using our surgical technique and patient selection. A secondary aim was to investigate factors that were associated with poorer outcomes for this procedure as well as complication rate in this cohort.

Methods: Theater records from a single spinal surgeon's practice were reviewed to identify patients that had undergone lumbar fusion for discogenic back pain with subsequent pedicle screw instrumentation removal (Expedium, DePuy Synthes) in the preceding 3 years with a minimum of 18 months follow-up.

Lumbar degenerative disc disease is extremely common. Current evidence supports surgery in carefully selected patients who have failed non-operative treatment and do not exhibit any substantial psychosocial overlay. Fusion surgery employing the correct grafting and stabilization techniques has long-term results demonstrating successful clinical outcomes.

Our aim was to compare the assessment of periprosthetic osteolysis around total knee arthroplasties using digital images against film-screen images. Simulated osteolytic lesions were created around 3 cadaveric total knee arthroplasties images acquired using fluoroscopic-assisted radiography and Computed Tomography. Three surgeons reviewed the film-screen images (AP/Lateral, Oblique, and Computed Tomography (CAT)) and the same images digitally.

Periprosthetic osteolysis is a common cause of revision of total knee arthroplasties (TKAs), with plain anteroposterior and lateral (APL) radiographs being the most common method for screening. The aim of this study was to examine the utility of lesion detection and volume appreciation with APL, paired oblique radiographs, and computed tomography. Defects of different sizes were created in 3 cadaveric knees with a cementless TKA in situ and imaged with APL, oblique, and computed tomography modalities.

Background: The Care of the Critically Ill Surgical Patient (CCrISP) course was adapted by the Royal Australasian College of Surgeons, being made compulsory for all Basic Surgical Trainees in 2001. The aim of this study was to evaluate whether the course objectives were achieved and identify strengths and weaknesses.

Methods: A retrospective cohort study was completed, after CCrISP Committee support of the proposed conduct, by distribution of questionnaires to instructors and trainees who had completed CCrISP in 2006 or earlier.
