1. Fifteen patients with spina bifida occulta are described in whom the fifth lumbar spinous process was pressing on the fibrous membrane that closes the spina bifida, or on the bony stumps of the defective lamina. 2. That this is a cause of low back pain, with or without pain referred to the lower limbs, is supported by the findings at operation and the results of treatment. 3. Eleven patients were treated by operation; in each the spinous process of the fifth lumbar vertebra pressed against the spina bifida, either directly or through the vestigial remnant of the first sacral spinous process. 4. In eight cases the fibrous membrane was adherent to the
The optimal procedure for the treatment of ossification of the posterior longitudinal ligament (OPLL) remains controversial. The aim of this study was to compare the outcome of anterior cervical ossified posterior longitudinal ligament en bloc resection (ACOE) with posterior laminectomy and fusion with bone graft and internal fixation (PTLF) for the surgical management of patients with this condition. Between July 2017 and July 2019, 40 patients with cervical OPLL were equally randomized to undergo surgery with an ACOE or a PTLF. The clinical and radiological results were compared between the two groups.Aims
Methods
This study, using a surgeon-maintained database, aimed to explore the risk factors for surgery-related complications in patients undergoing primary cervical spine surgery for degenerative diseases. We studied 5,015 patients with degenerative cervical diseases who underwent primary cervical spine surgery from 2012 to 2018. We investigated the effects of diseases, surgical procedures, and patient demographics on surgery-related complications. As subcategories, the presence of cervical kyphosis ≥ 10°, the presence of ossification of the posterior longitudinal ligament (OPLL) with a canal-occupying ratio ≥ 50%, and foraminotomy were selected. The surgery-related complications examined were postoperative upper limb palsy (ULP) with a manual muscle test (MMT) grade of 0 to 2 or a reduction of two grade or more in the MMT, neurological deficit except ULP, dural tear, dural leakage, surgical-site infection (SSI), and postoperative haematoma. Multivariate logistic regression analysis was performed.Aims

Diastematomyelia is a rare congenital abnormality
of the spinal cord. This paper summarises more than 30 years’ experience
of treating this condition. Data were collected retrospectively
on 138 patients with diastematomyelia (34 males, 104 females) who
were treated at our hospital from May 1978 to April 2010. A total
of 106 patients had double dural
Cervical spondylosis is often accompanied by dizziness. It has
recently been shown that the ingrowth of Ruffini corpuscles into
diseased cervical discs may be related to cervicogenic dizziness.
In order to evaluate whether cervicogenic dizziness stems from the
diseased cervical disc, we performed a prospective cohort study
to assess the effectiveness of anterior cervical discectomy and
fusion on the relief of dizziness. Of 145 patients with cervical spondylosis and dizziness, 116
underwent anterior cervical decompression and fusion and 29 underwent
conservative treatment. All were followed up for one year. The primary
outcomes were measures of the intensity and frequency of dizziness.
Secondary outcomes were changes in the modified Japanese Orthopaedic
Association (mJOA) score and a visual analogue scale score for neck
pain.Aims
Patients and Methods
Little information is available about the incidence
and outcome of incidental dural tears associated with microendoscopic
lumbar decompressive surgery. We prospectively examined the incidence
of dural tears and their influence on the outcome six months post-operatively
in 555 consecutive patients (mean age 47.4 years (13 to 89)) who
underwent this form of surgery. The incidence of dural tears was
5.05% (28/555). The risk factors were the age of the patient and
the procedure of bilateral decompression via a unilateral approach.
The rate of recovery of the Japanese Orthopaedic Association score
in patients with dural tears was significantly lower than that in
those without a tear (77.7% Cite this article:
Fibrin glue, also known as fibrin sealant, is now established as a haemostatic agent in surgery, but its role in orthopaedic surgery is neither well known nor clearly defined. Although it was originally used over 100 years ago, concerns about transmission of disease meant that it fell from favour. It is also available as a slow-release drug delivery system and as a substrate for cellular growth and tissue engineering. Consequently, it has the potential to be used in a number of ways in orthopaedic surgery. The purpose of this review is to address its use in surgery of the knee in which it appears to offer great promise.
We present the clinical and radiological results of percutaneous vertebroplasty in the treatment of 58 vertebral compression fractures in 51 patients at a minimum follow-up of two years. Group 1 consisted of 39 patients, in whom there was no associated intravertebral cleft, whilst group 2 comprised 12 patients with an intravertebral cleft. The Oswestry disability index (ODI) and visual analogue scale (VAS) scores were recorded prospectively. The radiological evidence of kyphotic deformity, vertebral height, leakage of cement and bone resorption around the cement were studied restrospectively, both before and after operation and at the final follow-up. The ODI and VAS scores in both groups decreased after treatment, but the mean score in group 2 was higher than that in group 1 (p = 0.02 (ODI), p = 0.02 (VAS)). There was a greater initial correction of the kyphosis in group 2 than in group 1, although the difference was not statistically significant. However, loss of correction was greater in group 2. Leakage of cement was seen in 24 (41.4%) of 58 vertebrae (group 1, 32.6% (15 of 46); group 2, 75% (9 of 12)), mainly of type B through the basal vertebral vein in group 1 and of type C through the cortical defect in group 2. Resorption of bone around the cement was seen in three vertebrae in group 2 and in one in group 1. There were seven adjacent vertebral fractures in group 1 and one in group 2. Percutaneous vertebroplasty is an effective treatment for osteoporotic compression fractures with or without an intravertebral cleft. Nonetheless, higher rates of complications related to the cement must be recognised in patients in the presence of an intravertebral cleft.
Bone allografts can be used in any kind of surgery involving bone from minor defects to major bone loss after tumour resection. This review describes the various types of bone grafts and the current knowledge on bone allografts, from procurement and preparation to implantation. The surgical conditions for optimising the incorporation of bone are outlined, and surgeon expectations from a bone allograft discussed.
