The aim of this study was to reassess the rate of neurological, psoas-related, and abdominal complications associated with L4-L5 lateral lumbar interbody fusion (LLIF) undertaken using a standardized preoperative assessment and surgical technique. This was a multicentre retrospective study involving consecutively enrolled patients who underwent L4-L5 LLIF by seven surgeons at seven institutions in three countries over a five-year period. The demographic details of the patients and the details of the surgery, reoperations and complications, including femoral and non-femoral neuropraxia, thigh pain, weakness of hip flexion, and abdominal complications, were analyzed. Neurological and psoas-related complications attributed to LLIF or posterior instrumentation and persistent symptoms were recorded at one year postoperatively.Aims
Methods
During revision procedures for aseptic reasons, there remains a suspicion that failure may have been the result of an undetected subclinical infection. However, there is little evidence available in the literature about unexpected positive results in presumed aseptic revision spine surgery. The aims of our study were to estimate the prevalence of unexpected positive culture using sonication and to evaluate clinical characteristics of these patients. All patients who underwent a revision surgery after instrumented spinal surgery at our institution between July 2014 and August 2016 with spinal implants submitted for sonication were retrospectively analyzed. Only revisions presumed as aseptic are included in the study. During the study period, 204 spinal revisions were performed for diagnoses other than infection. In 38 cases, sonication cultures were not obtained, leaving a study cohort of 166 cases. The mean age of the cohort was 61.5 years (Aims
Patients and Methods
We report the results of vertebral column resection
(VCR) for paediatric patients with spinal deformity. A total of
49 VCRs in paediatric patients from four university hospitals between
2005 and 2009 with a minimum two-year follow-up were retrospectively
identified. After excluding single hemivertebral resections (n =
25) and VCRs performed for patients with myelomeningocele (n = 6),
as well as spondylectomies performed for tumour (n = 4), there were
14 patients who had undergone full VCR at a mean age of 12.3 years
(6.5 to 17.9). The aetiology was congenital scoliosis in five, neuromuscular
scoliosis in three, congenital kyphosis in two, global kyphosis
in two, adolescent idiopathic scoliosis in one and secondary scoliosis
in one. A total of seven anteroposterior and seven posterolateral approaches
were used. The mean major curve deformity was 86° (67° to 120°) pre-operatively
and 37° (17° to 80°) at the two-year follow-up; correction was a
mean of 54% (18% to 86%) in the anteroposterior and 60% (41% to
70%) in the posterolateral group at the two-year follow-up (p =
0.53). The mean Scoliosis Research Society-24 total scores were
100 (92 to 108) for the anteroposterior and 102 (95 to 105) for
the posterolateral group. There was one paraparesis in the anteroposterior
group necessitating urgent re-decompression, with a full recovery. Patients undergoing VCR are highly satisfied after a successful
procedure.
