Aims. The aim of this study was to explore risk factors for complications associated with dural tear (DT), including the types of DT, and the intra- and postoperative management of DT. Patients and Methods. Between 2012 and 2017, 12 171 patients with degenerative lumbar diseases underwent primary lumbar spine surgery. We investigated five categories of potential predictors: patient factors (sex, age, body mass index, and primary disease), surgical factors (surgical procedures, operative time, and estimated blood loss), types of DT (inaccessible for suturing/clipping and the presence of cauda equina/nerve root herniation), repair techniques (suturing, clipping, fibrin glue, polyethylene glycol (PEG) hydrogel, and polyglycolic acid sheet), and postoperative management (drainage duration). Postoperative complications were evaluated in terms of dural leak, prolonged bed rest, headache, nausea/vomiting, delayed wound healing, postoperative neurological deficit, surgical site infection (SSI), and reoperation for DT. We performed multivariable regression analyses to evaluate the predictors of postoperative complications associated with DT. Results. In total, 429/12 171 patients (3.5%) had a DT. Multivariable analysis revealed that PEG hydrogel significantly reduced the incidence of dural leak and prolonged bed rest, and that patients treated with sealants (fibrin glue and PEG hydrogel) significantly less frequently suffered from headache. A longer drainage duration significantly increased the incidence of headache, nausea/vomiting, and delayed wound healing. Headache and nausea/vomiting were significantly more prevalent in younger female patients. Postoperative neurological deficit and reoperation for DT significantly depended on the presence of cauda equina/nerve root herniation. A longer operative time was the sole independent risk factor for SSI and was also a risk factor for dural leak, prolonged bed rest, and nausea/vomiting. Conclusion. Sealants, particularly PEG hydrogel, may be useful in reducing symptoms related to cerebrospinal fluid leakage, whereas prolonged drainage may be unnecessary. Younger female patients should be carefully treated when DT occurs. Cite this article: Bone Joint J 2019;101-B:1115–1121

Aims. The aim of the study was to determine if there was a direct correlation between the pain and disability experienced by patients and size of their disc prolapse, measured by the disc’s cross-sectional area on T2 axial MRI scans. Methods. Patients were asked to prospectively complete visual analogue scale (VAS) and Oswestry Disability Index (ODI) scores on the day of their MRI scan. All patients with primary disc herniation were included. Exclusion criteria included recurrent disc herniation, cauda equina syndrome, or any other associated spinal pathology. T2 weighted MRI scans were reviewed on picture archiving and communications software. The T2 axial image showing the disc protrusion with the largest cross sectional area was used for measurements. The area of the disc and canal were measured at this level. The size of the disc was measured as a percentage of the cross-sectional area of the spinal canal on the chosen image. The VAS leg pain and ODI scores were each correlated with the size of the disc using the Pearson correlation coefficient (PCC). Intraobserver reliability for MRI measurement was assessed using the interclass correlation coefficient (ICC). We assessed if the position of the disc prolapse (central, lateral recess, or foraminal) altered the symptoms described by the patient. The VAS and ODI scores from central and lateral recess disc prolapses were compared. Results. A total of 56 patients (mean age 41.1 years (22.8 to 70.3)) were included. A high degree of intraobserver reliability was observed for MRI measurement: single measure ICC was 0.99 (95% confidence interval (CI) from 0.97 to 0.99 (p < 0.001)). The PCC comparing VAS leg scores with canal occupancy for herniated disc was 0.056. The PCC comparing ODI for herniated disc was 0.070. We found 13 disc prolapses centrally and 43 lateral recess prolapses. There were no foraminal prolapses in this group. The position of the prolapse was not found to be related to the mean VAS score or ODI experienced by the patients (VAS, p = 0.251; ODI, p = 0.093). Conclusion. The results of the statistical analysis show that there is no direct correlation between the size or position of the disc prolapse and a patient’s symptoms. The symptoms experienced by patients should be the primary concern in deciding to perform discectomy. Cite this article: Bone Joint J 2022;104-B(6):715–720

We present a case of delayed presentation of a subdural haematoma causing cauda equina syndrome which occurred 96 hours after a spinal anaesthetic had been administered for an elective total hip replacement in an 86-year-old man. The patient had received low-molecular-weight heparin anticoagulation which had been delayed until 12 hours postoperatively. No other cause of the haemorrhage could be identified

We have treated 15 patients with massive lumbar disc herniations non-operatively. Repeat MR scanning after a mean 24 months (5 to 56) showed a dramatic resolution of the herniation in 14 patients. No patient developed a cauda equina syndrome. We suggest that this condition may be more benign than previously thought

Aims. We present the results of correcting a double or triple curve adolescent idiopathic scoliosis using a convex segmental pedicle screw technique. Patients and Methods. We reviewed 191 patients with a mean age at surgery of 15 years (11 to 23.3). Pedicle screws were placed at the convexity of each curve. Concave screws were inserted at one or two cephalad levels and two caudal levels. The mean operating time was 183 minutes (132 to 276) and the mean blood loss 0.22% of the total blood volume (0.08% to 0.4%). Multimodal monitoring remained stable throughout the operation. The mean hospital stay was 6.8 days (5 to 15). Results. The mean post-operative follow-up was 5.8 years (2.5 to 9.5). There were no neurological complications, deep wound infection, obvious nonunion or need for revision surgery. Upper thoracic scoliosis was corrected by a mean 68.2% (38% to 48%, p < 0.001). Main thoracic scoliosis was corrected by a mean 71% (43.5% to 8.9%, p < 0.001). Lumbar scoliosis was corrected by a mean 72.3% (41% to 90%, p < 0.001). No patient lost more than 3° of correction at follow-up. The thoracic kyphosis improved by 13.1° (-21° to 49°, p < 0.001); the lumbar lordosis remained unchanged (p = 0.58). Coronal imbalance was corrected by a mean 98% (0% to 100%, p < 0.001). Sagittal imbalance was corrected by a mean 96% (20% to 100%, p < 0.001). The Scoliosis Research Society Outcomes Questionnaire score improved from a mean 3.6 to 4.6 (2.4 to 4, p < 0.001); patient satisfaction was a mean 4.9 (4.8 to 5). . Conclusions. This technique carries low neurological and vascular risks because the screws are placed in the pedicles of the convex side of the curve, away from the spinal cord, cauda equina and the aorta. A low implant density (pedicle screw density 1.2, when a density of 2 represents placement of pedicle screws bilaterally at every instrumented segment) achieved satisfactory correction of the scoliosis, an improved thoracic kyphosis and normal global sagittal balance. Both patient satisfaction and functional outcomes were excellent. Cite this article: Bone Joint J 2017;99-B:1080–7

Fifty-five patients with severe pain from spinal instability secondary to metastatic cancer were referred to Hope Hospital, none being judged to be in a terminal condition. One patient had too extensive disease for surgery so 54 were treated by 55 spinal stabilisations; 49 obtained complete relief of pain and two had partial relief. There were three failures. Twenty-eight of the patients had clinical evidence of spinal cord or cauda equina compression and were decompressed at the time of stabilisation. Of these, 20 had major recovery of neurological function. Patients with pre-operative evidence of extradural tumour had 'prophylactic' decompression at the time of stabilisation; none of these patients later developed signs of cord or cauda equina compression. The results suggest that alleviation of pain and restoration of mobility are best achieved by segmental spinal stabilisation; a few patients require a combined anterior and posterior stabilisation. Postoperative radiotherapy should be given whenever possible, and the causative tumour should be treated by endocrine or chemotherapy, as indicated

There have been a few reports of patients with a combination of lumbar and thoracic spinal stenosis. We describe six patients who suffered unexpected acute neurological deterioration at a mean of 7.8 days (6 to 10) after lumbar decompressive surgery. Five had progressive weakness and one had recurrent pain in the lower limbs. There was incomplete recovery following subsequent thoracic decompressive surgery. The neurological presentation can be confusing. Patients with compressive myelopathy due to lower thoracic lesions, especially epiconus lesions (T10 to T12/L1 disc level), present with similar symptoms to those with lumbar radiculopathy or cauda equina lesions. Despite the rarity of this condition we advise that patients who undergo lumbar decompressive surgery for stenosis should have sagittal whole spine MRI studies pre-operatively to exclude proximal neurological compression.

We describe a case of bilateral weakness of the lower limbs, sensory disturbance and intermittent urinary incontinence, secondary to untreated Gitelman’s syndrome, in a 42-year-old female who was referred with presumed cauda equina syndrome. On examination, the power of both legs was uniformly reduced, and the perianal and lower-limb sensation was altered. However, MRI of the lumbar spine was normal. Measurements of serum and urinary potassium were low and blood gas analysis revealed metabolic alkalosis. Her symptoms resolved following potassium replacement. We emphasise the importance of measurement of the plasma and urinary levels of electrolytes in the investigation of patients with paralysis of the lower limbs and suggest that they, together with blood gas analysis, allow the exclusion of unusual causes of muscle weakness resulting from metabolic disorders such as metabolic alkalosis

A three-month-old girl presented with a massive abdominal tumour arising from the right lumbar region. Microscopic examination of a biopsy specimen showed a typical neuroblastoma. No treatment was given except that necessary symptomatically for paralysis caused by compression of the cauda equina. Spontaneous regression was accompanied by maturation to a small ganglioneuroma, found at necropsy examination at the age of ten years. Death was from urinary infection due to a persistent neurogenic bladder

1. A detailed analysis of the anatomy of spondylolisthesis reveals many causes of serious interference with the nerve roots. 2. These anatomical findings can be correlated with the symptoms. 3. In association with spondylolisthesis, cases of disc prolapse, tuberculosis, and a cauda equina lesion are described. 4. Adequate decompression of the affected nerve root is essential in all cases with sciatica. The operative procedure is described. 5. The problem of arthrodesis will be discussed fully in a separate paper

1. An enterogenous cyst lying in the cauda equina opposite the third lumbar vertebra, and associated with spina bifida occulta of the fifth lumbar vertebra and spondylolisthesis of the fifth lumbar on the first sacral vertebra, is described in a man aged thirty-five suffering from chronic low back pain and sciatica. 2. Current embryological theories concerning the formation of intraspinal enterogenous cysts from primitive gut cells are further substantiated by the features of this case

The familiar picture of spinal tuberculosis is one of destruction of adjacent vertebral bodies and of the intervening disc. There are, however, other patients without these radiographic changes and with no clinical deformity who present with symptoms and signs of compression of the spinal cord or cauda equina. These patients fall into two different groups: those with tuberculosis of the neural arch; and those with extra-osseous extradural tuberculosis. Both may require laminectomy, but whereas the first has bony involvement and a cold abscess, the second has neither

We evaluated the nerve roots of the cauda equina by CT myelography in 36 patients aged from 11 to 19 years with lumbar disc herniation. On straight-leg-raising tests, six younger patients had isolated hamstring tightness with no sciatica (group A) and 30 had sciatic pain (group B). CT myelography showed that no patient in group A had associated nerve-root swelling, and that the roots were displaced posteriorly, but not compressed. In 21 of the group-B patients, swelling of the nerve roots was confirmed, with compression between the herniated disc and the superior articular process. Our findings suggest that hamstring tightness in these patients may be caused by a different mechanism from that which causes sciatic pain

1. Nineteen patients with spina bifida, myelomeningocele or lipoma of the cauda equina have been reviewed. Convex pes valgus was found in twenty-five feet. All patients had a neuromuscular imbalance between the evertors and invertors of the foot. 2. Results of release procedures only and of those which combine release procedures with tendon transfers are compared; they show that there is no consistently satisfactory operation for correction of the deformity when it exists with neuromuscular imbalance. 3. An operation in which release procedures are combined with the transfer of the peroneus brevis to the tibialis posterior and of the tibialis anterior to the neck of the talus is described. It has given satisfactory results in two out of three patients with paralytic convex pes valgus

1. Thirty-four patients with severe lumbo-sacral subluxation have been studied. Twenty-nine of these came for advice between the ages of nine and nineteen, and of these, twenty-five developed symptoms and signs of a characteristic syndrome. 2. The details of the syndrome are described: the essential features are spinal stiffness, a lordotic gait, resistance to straight leg raising, and in some cases evidence of interference with cauda equina or nerve root. 3. The danger of attempted reduction by traction is stressed, as well as the difficulties to be encountered during posterior lumbo-sacral fusion. 4. The reasons for operating are given; the results of spinal fusion were satisfactory. 5. The traditional apprehension concerning the effect of severe subluxation on childbirth has probably been over-stressed. 6. The tendency to slip was almost completely arrested by spinal fusion

1. A syndrome resulting from congenital lesions affecting the spinal cord and cauda equina, associated with spina bifida occulta, is described. 2. The syndrome consists of a progressive deformity of the lower limbs in children. One foot and the same leg grow less rapidly than the other. The foot develops a progressive deformity which begins as a cavo-varus and becomes a valgus one. Both lower limbs may be affected. There may be progression to sensory loss, trophic ulceration, disturbance of function of bowel and bladder and even paraplegia. 3. Methods of investigation including myelography are described. 4. Exploration of the spinal cord has been undertaken in twenty-four patients so affected. Extrinsic congenital lesions causing traction or pressure or a combination of traction and pressure on the spinal cord have been found in twenty-two of these. 5. In two-thirds of the patients some degree of improvement has followed operation

Thirteen patients, aged 7 to 45 years, have been treated for atypical forms of spinal tuberculosis at the Neurological Centres at Benghazi and Lahore. All presented with signs and symptoms of compression of the spinal cord or cauda equina, ranging from paraesthesiae and increasing weakness to paraplegia and loss of sphincter control. None of them showed visible or palpable spinal deformity nor the typical radiographic appearance of destruction of the intervertebral disc and the two adjoining vertebral bodies. These atypical cases fell into two well-defined groups: those with involvement of the neural arch only, with associated intraspinal cold abscesses, and those with involvement of a single vertebral body, resulting in its collapse and a radiographic appearance similar to that in secondary carcinoma of the vertebral body. The correct treatment in these two groups was diametrically opposed. Tuberculous disease of the neural arch was best traced by laminectomy; concertina collapse of a single vertebral body required cost-transversectomy and resection of the transverse process, the pedicle, and the portion of the vertebral body that was encroaching on the spinal canal

1. An analysis has been made of the clinical features and investigations in ninety-five cases of primary intraspinal tumours. 2. Loss of muscle power was the commonest symptom, and was often ignored until late in the course of the disease. 3. Two-thirds of the patients had no pain in the spinal region, although five of these had either extensive growths or radiographical evidence of bone erosion by tumour. 4. One-third of the patients had urinary symptoms, and two of them had acute retention initially attributed to prostatic obstruction. 5. In eighteen cases posture and gait were abnormal. The case histories of five of these patients are recorded, and they emphasise the importance of recognising lumbar spasm and hamstring tightness in young patients as signs of a cauda equina neoplasm. 6. All patients had some detectable sensory, motor, or reflex changes, and these were mostly bilateral. 7. Radiography, and cerebrospinal fluid manometry and analysis, were helpful in establishing the diagnosis. 8. Hysteria should not be diagnosed until all efforts have been made to prove otherwise
