Although there are several accepted methods of surgical treatment for single-level cervical radiculopathy, the choice depend on the surgeon's preference. The techniques may vary in peri-operative morbidity, short- and long-term outcome, but no study so far has analyzed their cost-effectiveness. This study might give some insight in balancing cost and effectiveness and deciding the right technique. Sixty consecutive patients (15 each group), mean age 36 (range 24-76 years) with single-level cervical disc disease underwent surgical treatment with four different techniques in two centers over the period of 1999-2005. The four groups were--(1) plate and tricortical autograft, (2) plate, cage, and bone substitute, (3) cage only, and (4) disc arthroplasty. The data was collected prospectively according to our protocol and subsequently analyzed. The clinical outcome was assessed comparing visual analog scale (VAS) of neck pain and, short form 12 (SF12) questionnaire both pre- and postoperatively. The radiological assessment was done for fusion rate and postoperative related possible complications at 3 months, 6 months, 1 year, and final follow-up. The cost analysis was done calculating the operative time, hospital stay, implant cost together. The mean follow-up period was 31 months (range 28-43 months). The clinical outcome in terms of VAS of neck and arm pain and SF12 physical and mental score improvement (P=0.001) were comparable with all four techniques. The radiological fusion rate was comparable to current available data. As the hospital stay was longer (average 5 days) with plate and autograft group, the total cost was maximum (average 2,920 pound sterling) with this group. There was satisfactory clinical and radiological outcome with all four techniques. Using the cage alone was the most cost-effective technique, but the disc arthroplasty was comparable to the use of cage and plate. Anterior cervical discectomy and fusion is an established surgical treatment for cervical radiculopathy. Single-level cervical radiculopathy was treated with four different techniques. The clinical outcome and cost-effectiveness were compared in this study.

Thirty-five patients who had thirty-seven mucous cysts excised from the distal interphalangeal joints were reviewed not less than one year later. Seven out of 25 which had been treated by simple excision recurred, whereas only one out of twelve treated by excision and skin closure with a rotation flap recurred.

Purpose This study analyses the complications of spinal deformity surgery in adults to highlight pre-disposing factors. Methods The clinical records and imaging were reviewed for 48 consecutive patients, 12 males and 36 females, with a mean age of 64 (31-86), who had surgery for spinal deformity. Mean follow-up time was 36 months (24-60). Patient data recorded were age, diagnosis and co-morbidities; deformity assessment: curve type, sagittal and coronal balance, Cobb angle. Operation details: number of instrumented levels, duration and intra-operative complications. Outcome: complications, re-operations, balance and Cobb angle. Results 28 patients (58 %) had at least 1, 15 patients (27 %) had 2 and 5 patients (9.5 %) had more than 2 comorbidities. Average time between 1st presentation and operation was 13 months (1-41). The mean number of levels fused was 10.8 (4-23). In addition to posterior pedicle screw instrumentation, 40 patients had chevron osteotomies and 8 had pedicle substraction osteotomies. Posterior interbody fusions were performed at one level in 17 of which 7 had 2 level fusion. Two patients had combined anterior and posterior approaches. Fusion to the pelvis was performed in 19 patients. There were a total of 27 major and minor complications in 19/48 (39.5 %) patients. Late complications included 5 patients who had revisions for proximal junctional kyphosis, 1 patient had revision for pseudoarthrosis and 4 patients had removal of mal-positioned screws. Conclusions Factors associated with high complication rate in adult spinal deformity surgery are age, co-morbidities and severe sagittal imbalance at the time of presentation.

Multimodal monitoring allows early detection of impending neurological deficit that is superior to a single monitoring modality. To achieve optimal use of monitoring, continuous communication between surgical, anaesthetic and neurophysiology teams are required. As a result of our experience we have incorporated in our consent procedure the discussion of monitoring and the possibility of needing to abandon the procedure, and completing in a staged fashion at a later date. We believe multimodal monitoring is the current gold standard for complex spinal deformity surgery.
