2. 1. Spinal cord ischemia : An experimental study of the spinal cord blood supply and peroperative ischemia detection by a new method of intrathecal monitoring

   Author : Lennart Christiansson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Spinal cord ischemia; Oxygen tension; Intrathecal monitoring; Ultrastructure; Aortic cross-clamping; Thoracoabdominal aneurysm; Kirurgi; Surgery; Kirurgi; anestesiologi; Anaesthesiology;

   Abstract : Spinal cord ischemia associated with thoracoabdominal aortic surgery may lead to devastating neurological complications. Improvement in bypass techniques and various adjunctive measures has reduced its incidence, but still 5-10 % of the patients develop postoperative paraplegia. READ MORE

4. 2. Fixation of Spinal Implants : Clinical and Experimental Studies on the Effects of Hydroxyapatite Coating

   Author : Bengt Sandén; Acke Ohlin; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Hydroxyapatite; pedicle screw; histomorphometry; fixation; radiolucent zones; screw loosening; Kirurgi; Surgery; Kirurgi; Orthopaedics; ortopedi;

   Abstract : Loosening of implants is a frequent complication in orthopaedic surgery. The aim of this thesis was to evaluate hydroxyapatite coating of pedicle screws with mechanical and histological methods and to correlate the results with the radiological findings.Hydroxyapatite (HA) coating of pedicle screws was investigated in experimental studies in sheep.

5. 3. Spinal cord oxygenation during thoracic aortic clamping in pigs

   Author : Anders Hellberg; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Thoracoabdominal aortic replacement; spinal cord ischaemia; cerebrospinal; intrathecal monitoring; oxygen tension; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

   Abstract : Despite a dramatic reduction in the mortality associated with thoracoabdominal aorticreplacement during the past 40 years, spinal cord ischaemia that results in paraplegia remainsa serious complication. Simple and reliable intraoperative monitoring techniques are neededto detect impending neurological deficit in time to prevent permanent damage. READ MORE

6. 4. Neuroprotection and axonal regeneration after peripheral nerve injury

   Author : Dag Welin; Lev N. Novikov; Lars B. Dahlin; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dorsal root ganglion; Motoneuron; Axonal reaction; Peripheral nerve injury; Nerve regeneration; N-acetylcysteine; Hand surgery; Handkirurgi; Anatomy; Anatomi; anatomi; Human Anatomy; handkirurgi; hand surgery;

   Abstract : Following microsurgical reconstruction of injured peripheral nerves, severed axons are able to undergo spontaneous regeneration. However, the functional result is always unsatisfactory with poor sensory recovery and reduced motor function. READ MORE

7. 5. Cervical Radiculopathy: A Study With Selective Nerve Root Blocks

   Author : Leif Anderberg; Neurokirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; orthopaedics; Contrast distribution; Nerve root block; Cervical radiculopathy; Kirurgi; traumatology; Treatment; ortopedi; traumatologi;

   Abstract : Cervical radiculopathy is diagnosed by history, clinical examination of the patient and magnetic resonance imaging (MRI) of the cervical spine. In many of the patients undergoing this diagnostic strategy, the nerve root/roots responsible for the radicular pain is difficult to define as clinical examination and MRI investigation does not provide information enough.
