To quantify the duration of symptoms and the treatment modalities employed prior to surgery in patients undergoing lumbar and cervical nerve root decompression and to assess the evidence of these non-surgical treatments. Pre- and post operative questionnaires completed by consecutive patients. 514 people undergoing consecutive cervical or lumbar nerve root decompression between March 2007 to October 2009. Pre-operative severity and duration of pain, functional limitations and treatment received. Post-operative pain severity and change in functional limitations. Evidence in the literature for efficacy of treatment modalities employed. Mean duration of pre-operative symptoms was 23 months (range 1 to 360). 91% took regular medication for pain, 83% received one or more physical therapy, 24% received injection therapy. There was improvement in both pain scores (mean pre-op 7.3; post-op 3.0) and 78% of the commonly reported functional limitations, walking, sleep and work. We found extremely limited evidence to support the other treatment modalities employed. Patients spend many months unnecessarily in pain, consuming considerable resources and may suffer significant side effects from ineffective treatment for pain emanating from nerve root compression. Surgical nerve root decompression relieves pain and restores function. Despite this a specialist opinion is often delayed. Early referral for specialist opinion is almost certainly more humane, cost effective, and time-limits the journey on the not so magic roundabout

Purpose. Posterior lumbar fusion using minimally invasive surgical (MIS) techniques are reported to minimise postoperative pain, soft tissue damage and length of hospital stay when compared to the traditional open procedure. Methods. This is a review of patients who underwent MIS for posterolateral lumbar fusion in a single practice over a 2-year period. Results. Twenty-eight patients underwent this procedure. The median age was 57 (range 34-80). Male:female ratio was 1:1. The most common symptom was radicular pain (n=26). Two patients had back pain without radicular symptoms. Primary degenerative spondylolisthesis was seen in 22 patients and post-laminectomy spondylolisthesis in 3 patients. Transforaminal interbody fusion (TLIF) with pedicle screw fixation was the commonest procedure (20) while the rest had pedicle screw fixation and inter-transverse fusion. Along with fusion, nerve root decompression alone was performed in 19, while 5 had decompression of the central spinal canal. Intra-operative navigation was used to assist screw placement in 5 patients. The typical hospital stay was 3 days. All but two patients were mobilised the same or the following day. Twenty-one patients with radiculopathy (80%) reported improvement in VAS at 6-months. One patient suffered irreversible nerve root injury (L5). Significant pedicle breach without nerve injury by a screw was seen in one patient. Conclusion. Minimally invasive TLIF and pedicle screw fixation lumbar degenerative condition is a safe procedure with complications comparable to traditional open techniques. Minimal muscle dissection and soft tissue damage allows for earlier ambulation and reduced hospital stay. The procedure however required longer operative time and increased exposure to intra-operative x-rays

The widespread use of MRI has revolutionised the diagnostic process for spinal disorders. A typical protocol for spinal MRI includes T1 and T2 weighted sequences in both axial and sagittal planes. While such an imaging protocol is appropriate to detect pathological processes in the vast majority of patients, a number of additional sequences and advanced techniques are emerging. The purpose of the article is to discuss both established techniques that are gaining popularity in the field of spinal imaging and to introduce some of the more novel ‘advanced’ MRI sequences with examples to highlight their potential uses.

Aims

We reviewed 34 consecutive patients (18 female-16 male) with isthmic spondylolysis and grade I to II lumbosacral spondylolisthesis who underwent in situ posterolateral arthodesis between the L5 transverse processes and the sacral ala with the use of iliac crest autograft. Ten patients had an associated scoliosis which required surgical correction at a later stage only in two patients with idiopathic curves unrelated to the spondylolisthesis.
