Impact of Patient-specific Factors and Spinopelvic Alignment on the Development of Adjacent Segment Degeneration After Short-segment Lumbar Fusion.

Study Design: Prospective cross-sectional cohort study.

Objectives: The main purpose of this study was to evaluate the association between demographical, surgery-related and morphologic parameters, and the development or progress of adjacent segment degeneration (ASD) after short-segment lumbar fusions.

Summary Of Background Data: ASD is a major long-term complication after lumbar fusions.

Outcome of group physical therapy treatment for non-specific low back pain patients can be predicted with the cross-culturally adapted and validated Hungarian version STarT back screening tool.

Purpose: The STarT Back Tool was developed to identify the specific modifiable prognostic factors for non-specific low back pain and to classify the patients into risk groups; low, medium and high risk of chronicity. Applied therapeutic approaches often involve group physical therapy. The aim of this study was the cross-cultural adaptation and validation of the Hungarian version of the STarT Back Tool and to investigate the predictive ability for global treatment outcome.

Global Treatment Outcome after Surgical Site Infection in Elective Degenerative Lumbar Spinal Operations.

Surgical site infection (SSI) is a serious complication after routine lumbar spinal operations, and its effect on global treatment outcome (GTO) is less reported. The aim of the current study was to measure the impact of SSI on outcome, which was evaluated with patient reported outcome measures (PROMs) and patients' subjective judgment (GTO). A total of 910 patients underwent primary a single- or two-level lumbar decompression or instrumented fusion surgical procedure.

Correction to: Association of vitamin D receptor gene polymorphisms with disc degeneration.

Unfortunately, the following reference was missed out in the original publication.

Association of vitamin D receptor gene polymorphisms with disc degeneration.

Purpose: Numerous candidate genes and single-nucleotide polymorphisms (SNPs) have been identified in the background of lumbar disc degeneration (LDD). However, in most of these underpowered studies, definitions of LDD are inconsistent; moreover, many of the findings have not been replicated and are contradictory. Our aim was to characterize LDD by well-defined phenotypes and possible endophenotypes and analyse the association between these and candidate vitamin D receptor (VDR) gene polymorphisms on a large (N = 1426) dataset.

Risk factors of non-specific spinal pain in childhood.

Purpose: Non-specific spinal pain can occur at all ages and current evidence suggests that pediatric non-specific spinal pain is predictive for adult spinal conditions. A 5-year long, prospective cohort study was conducted to identify the lifestyle and environmental factors leading to non-specific spinal pain in childhood.

Materials And Methods: Data were collected from school children aged 7-16 years, who were randomly selected from three different geographic regions in Hungary.

Primary prevention of disc degeneration-related symptoms.

Introduction: It has been shown previously that a history of low back pain often begins in childhood or adulthood. Indeed, the prevalence of severe back symptoms among schoolchildren is not insignificant. Possibilities for the primary prevention of intervertebral disc degeneration-related conditions are poorly reported in the literature despite the assumed socio-economical impact of the prevention of these conditions.

Biomechanical comparison of two stabilization techniques for unstable sacral fractures.

Aim: The purpose of the study was to assess the stability provided by an ilio-iliac dorsal plate fixation technique using an AO narrow DCP on the pelvic brim in vertically and rotationally unstable type-C pelvic ring injuries.

Materials And Methods: We examined 12 fresh cadaver pelvises in a single limb stance load. A type-C pelvic ring injury (a type I lateral sacral fracture in the classification of Denis with symphysis pubis rupture) was performed on the cadaver specimen and fixed with a four-hole narrow dynamic compression plate to stabilize the symphysis pubis rupture; the sacrum fracture was stabilized either anteriorly with two 3-hole reconstruction plates ("anterior plate osteosynthesis") or with a posterior fixation using a 12-hole narrow DCP.

Unstable pelvic fractures in children.

A total of 3561 freshly injured children received treatment at the paediatric trauma department of the National Institute of Traumatology between 1984 and 1994. Out of these 38 (approx. 1%) had pelvic fractures.

[Ossovenography as a diagnostic criterion of post-traumatic femoral head necrosis in internal fixation devices].

Despite advances in the field of orthopedic surgery, necrosis of the femoral head still remains a serious problem. Under normal conditions magnetic resonance tomography (MRT) is the gold standard for early diagnosis. Because of magnetic interference, this technique is not applicable in the diagnosis of posttraumatic necrosis with internal fixation, however.

[Aseptic femur head necrosis and therapeutic possibilities by using a bone graft with a vascular pedicle].

The review of the occurrence, etiopathology, classification and diagnosis of the aseptic necrosis of the femoral head is followed by the description of the method of transplantation of the vascular pedicled bone graft. During 5 years implantation of 12 vascular pedicled bone grafts in 10 young patients with severe and of major extension necrosis of the femoral head was carried out. The early result was in every case the quick and significant decrease of pains and that the necrosis did not progress.

Yersinia enterocolitica infection of animals and human contacts.

Infective animal sources and persons in contact with animals were investigated for Yersinia enteroclotica. The 68 isolates from 3115 animals belonged to four serogroups. The most frequent was serogroup O3 (62 strains) found mainly in pigs (41 strains).

Incidence of non-cholera vibrios in Hungary.

In the period 1971 to 1976, 200 non-cholera vibrio (NCV) strains were isolated in Hungary; 18 of the cultures were derived from 34 729 faecal and 182 from 237 surface water samples. Ninety-two strains belonged to the Heiberg-Smith group I and 108 to group II. Two strains failed to give the string test and 3 were pteridine resistant.

[Analysis of femoral shaft fractures (author's transl)].

Authors after having reviewed the literature analyse 157 healed cases from their own material of 198 femoral shaft fractures. Fractures between the subtrochanteric and supracondylar region has been considered. 2/3 part of the injured have been victims of traffic accidents, 1/6 part suffering severe polytraumatisation.

A five-year survey of human Yersinia enterocolitica infections in Hungary.

Human infections associated with Yersinia enterocolitica in Hungary in the years 1969-1974 have been surveyed. During this period the public health laboratory network isolated 1355 strains from 1096 persons. The number of isolates according to sero-groups was: 1343 O3, 6 O9, 2 O1, 2a, 3 and 1 strain for O5, O6, O1O and O15 each.
