[The effect of joint facet asymmetry on the pathogenesis of lower segments of the lumbar spine].

Magnetic resonance and computed tomography scans of L4/5 and L5/S1 levels in 129 patients operated for herniated intervertebral disc were assessed to establish the relationship of facet joint asymmetry, disc prolapse and degenerative disease. Facet angle and spinal stenosis were measured. Statistical analysis revealed significant correlation between facet joint asymmetry and disc disease or degenerative stenosis within lumbar spine.

[Functional marker "Repty" for evaluation of independence in patients with paraplegia].

The use of "Repty" index for functional assessment of treatment results in 40 patients with paraplegia aged 13-65 (mean 37) is presented. The outcome has been compared with Barthel Index- the oldest scale assessing activities of daily living. High correlation of both scales sensitivity was found; in some functional parameters "Repty" index was more sensitive.

[Transthoracic approach to the thoracic spine via the rib cage].

Transthoracal approach to the thoracic spine is presented. It has been used in 19 patients with trauma or tumor within thoracic spine. This approach allowed for direct access to the vertebral body where the pathology was located. Transthoracal approach, however, should be performed by a surgeon with sufficient knowledge of thoracic surgery.

[Treatment of traumatic spondylolisthesis of the axis].

Classification of hangman's fracture according to Levine has been presented. The classification enables individualization of the management depending on the mechanism of the injury. A series of 37 patients with traumatic spondylolisthesis of the axis has been analyzed. Skull traction in flexion injury cases led to the increased dislocation.

[Fracture of the dens--conservative or surgical treatment?].

An analysis of 28 cases of dens fracture has shown that conservative treatment is generally sufficient in Anderson type I and type III fractures. In type II fractures surgical treatment is indicated, especially if the fracture is dislocated, complicated by neurological impairment or has occurred in the elderly.

Results of conservative treatment of unilateral cervical spine dislocations.

Unilateral cervical dislocations are less common and have fewer accompanying neurological complications than bilateral dislocations. Being therefore rated as "less serious", these injuries are often treated non-operatively. A review of 292 patients presenting with acute spine injuries revealed 32 cases of unilateral dislocation (11%). Analysis of their management showed that non-operative treatment was mostly unsatisfactory. Twenty-four of the 32 (75%) eventually required surgical correction. Surgery led to good results in all of these cases. We recommend surgery as a method of choice for patients with unilateral cervical dislocations.

[Treatment of the infected pseudoarthrosis of the tibia by the Harmon method].

The principles of treatment of tibial pseudoarthroses complicated by skin and soft tissue loss with the use of cancellous bone grafts from posterolateral approach to the tibia by Harmon method were discussed. The detailed surgical technique was presented. Management of 3 patients that resulted in bone union was described.

[Use of contractors in unstable fractures of the thoraco-lumbar spine].

The results obtained after the use of contractors in surgical treatment of 30 vertebral body fractures with their wedging and lesion of the posterior ligaments, while the posterior wall of the vertebra in the thoracic-lumbar spine was preserved, has been presented. It is a relatively simple surgical method enabling stabilization of fracture, reconstruction of the vertebral canal and improvement of neurological condition.

[Evaluation of the risk of internal contamination of persons working in isotope laboratories].

The investigation covered 484 workers. Altogether 1787 determinations have been made, in this--1648 internal contaminations and 139 contaminations of air, hand skin and working surfaces. The internal contaminations (22% of results) resulted mainly from deviation from radiological protection rules and were reduced through certain changes. Those were tritium contaminations (application of tritium radioluminiscence dyes) and 125--and 131-iodine radioisotopes (in nuclear medicine laboratories) the highest levels of which were 20 mSv and 0.25% ALI respectively. The results of 238Pu air contamination measurements have indicates that the dust arising during the production of smoke detectors (with 238PuO2 sources) probably has no respirable fraction properties, which confines its absorption in lower segments of the respiratory tract. It has been demonstrated that in Poland there is no need of constructing a permanent central system of internal contamination control.
