[Percutaneous osteosynthesis of pelvic fractures with CT control].
Pelvis fractures, most often multiple, are frequently unstable. Orthopedic treatment is hardly bearable (traction in bed sometimes up to 45 days), the open reduction and internal fixation (ORIF) is heavy. Percutaneous fluoroscopy guided fixation lacks precision in depth. Percutaneous screw fixation with CT scan control answers these drawbacks and represents a quick solution, with few hazard when performed by a trained team and allows a very early resumption of standing.
[Retroperitoneoscopic anterior approach to the L2, L3, L4 vertebral bodies].
PURPOSE OF THE STUDY: We present a technique of retroperitoneal video assisted anterior approach of vertebral bodies and adjacent discs on L2-L3-L4 levels without CO2 insufflation. MATERIALS: A videosurgical material is required as well as fluoroscopic control. Ordinary anesthesia methods can be used. The patient is placed in right lateral decubitus. Ay. A3 cm incision is targeted moderately anteriorly at the level of the vertebra. Dissection of the retroperitoneal space is begun by blunt finger dissection and completed by a balloon. A camera is inserted. CO2 insufflation is not used for this open video-assisted technique. METHODS: We have performed 12 arthrodeses with this technique, 11 of them without corporectomy. In one case, a corporectomy with peroneal graft was used. RESULTS: Eleven arthrodesis fused. The possible complications are the same as with a full open procedure. DISCUSSION: Extension of this approach is limited cranially by the 12th rib and caudally by the iliac crest. CONCLUSION: Although this is an easy to perform mini open technique, a learning curve is necessary. Conservation to a full open procedure is possible at any point in the procedure.
[Amelioration of perioperative somatosensory evoked potentials in the surgery of injuries of the spine].
Somatosensory evoked potentials were performed in 38 patients with traumatic spine pre, per and postoperatively. In 3 cases, the S.E.Ps altered before surgery, were improved after decompression and reduction. This S.E.Ps improvement was associated to clinical improvement. Even though this study was carried out on few cases, it shows prognosis and diagnosis value of intraoperative S.E.Ps in traumatic spine surgery.
[Implanting an osteosynthesis screw in the first sacral vertebra].
An original screwing technique is presented for the first sacral vertebra. A pediculocorporal position is proposed based on anatomical and experimental studies. The screw is placed obliquely medially in the horizontal plane, with the tip, in the sagittal plane, coming just under the first sacral end-plate which can be perforated in cases when a definitive implant for arthrodesis needs to be particularly solid.
Lumbar spine, sport and actual treatment.
Low back pains are very frequent in athletes by microtraumatisms and sudden efforts. The prolapse of the nucleus pulposus is created. After the failure of correct medical treatment, some new technics give good results: chemonucleolysis, trans-cutaneous nucleotomy, microdiscectomy. These techniques permit a faster and more active return to effort. The choice must be perfect: clinical examination and imagery manage this advance.
