The optimal method for the management of neglected traumatic bifacetal dislocation of the subaxial cervical spine has not been established. We treated four patients in whom the mean delay between injury and presentation was four months (1 to 5). There were two dislocations at the C5-6 level and one each at C4-5 and C3-4. The mean age of the patients was 48.2 years (27 to 60). Each patient presented with neck pain and restricted movement of the cervical spine. Three of the four had a myelopathy. We carried out a two-stage procedure under the same anaesthetic. First, a posterior soft-tissue release and partial facetectomy were undertaken. This allowed partial reduction of the dislocation which was then supplemented by interspinous wiring and corticocancellous graft. Next, through an anterior approach, discectomy, tricortical bone grafting and anterior cervical plating were carried out. All the patients achieved a nearly anatomical reduction and sagittal alignment. The mean follow-up was 2.6 years (1 to 4). The myelopathy settled completely in the three patients who had a pre-operative neurological deficit. There was no graft dislodgement or graft-related problems. Bony fusion occurred in all patients and a satisfactory reduction was maintained. The posteroanterior procedure for neglected traumatic bifacetal dislocation of the subaxial cervical spine is a good method of achieving sagittal alignment with less risk of iatrogenic neurological injury, a reduced operating time, decreased blood loss, and a shorter hospital stay compared with other procedures

PURPOSE OF THE STUDY. The anterior approach to the thoracic and lumbar spine is used with increasing frequency for various indications. With the advent of prosthetic intervertebral disc replacement, its use has become even more frequent and has often been associated with serious complications. The aim of this study was to evaluate vascular complications in patients who underwent anterior spinal surgery of the thoracic and lumbar spine. MATERIAL. We performed a total of 531 operations of the thoracolumbar spine from the anterior approach. In 12 cases, after exposure of the body of the first or second thoracic vertebrae, we employed the Smith-Robinson technique to expose the cervical spine. We used sternotomy in six, posterolateral thoracotomy in 209, pararectal retroperitoneal approach in 239, anterolateral lumbotomy in 58 and the transperitoneal approach in seven patients. The aim of surgery was somatectomy in 190 patients and discectomy in 341 patients. Sternotomy and transperitoneal approaches were carried out by a thoracic or vascular surgeon and all the other procedures were done by the first author. The indications for spinal surgery included an accident in 171, tumour in 56, spondylodiscitis in 43 and a degenerative disease in 261 patients. METHODS. The Smith-Robinson approach was used for exposure of T1 or T2. Sternotomy was indicated for treatment of T2–T4 and also T1 in the patients with a short, thick neck. Access to T3–L1 was gained by posterolateral thoracotomy, in most cases performed as a minimally invasive transpleural procedure. For access to the lumbar spine we usually used the retroperitoneal approach from a pararectal incision or lumbotomy. We preferred the pararectal retroperitoneal approach in L2–S1 degenerative disease, L5 fractures, and L5–S1 spondylodiscitis. We carried out lumbotomy in patients with trauma, tumors and L1–L4 spondylodiscitis. The transperitoneal approach from lower middle laparotomy was used only in tumors at L5 or L4. The patients were followed up for 2 to 96 months (average, 31.4 months) after anterior spinal surgery. RESULTS. In 12 patients treated by the Smith-Robinson procedure and in six patients undergoing sternotomy, neither early nor late signs of any injury to major blood vessels or internal organs were recorded. The 209 patients with posterolateral thoracotomy were also free from any signs of vascular injury, but trauma to the thoracic duet was recorded in one case. We found injury to major blood vessels in three patients in the group treated by the pararectal retroperitoneal procedure. In the total of 531 anterior spinal surgery procedures this accounts for 0.56 %; of the 304 lumbar operations and 239 pararectal retroperitoneal operations it is 0.99 % and 1.26 %, respectively. In one patient the vascular injury was associated with trauma to the ureter. CONCLUSIONS. The technique of anterior approach is safe only in the hands of experienced spinal surgeons with long experience. In institutions where anterior spinal surgery is not a routine method it is advisable to involve a vascular or cardiac surgeon. However, the most important point is to know when not to operate

Objectives

The aim of this systematic literature review was to assess the clinical level of evidence of commercially available demineralised bone matrix (DBM) products for their use in trauma and orthopaedic related surgery.

Methods

A total of 17 DBM products were used as search terms in two available databases: Embase and PubMed according to the Preferred Reporting Items for Systematic Reviews and Meta Analyses statement. All articles that reported the clinical use of a DBM-product in trauma and orthopaedic related surgery were included.
