[Usefulness of HA+beta-TCP in bone defects repair during revision hip and knee arthroplasty].

Background: Bone deficiency can present a surgical challenge during revision total hip and knee arthroplasty. The amount of bone grafts available for surgical purposes is insufficient. Synthetic bone substitutes can eliminate the risk of infection transmission.

[Total hip arthroplasty after previous support proximal femoral osteotomy].

Clinical outcome and technical difficulties observed after total hip arthroplasty (THA) subsequent to support proximal femur osteotomy were studied in 6 total hip arthroplasties. 6 patients were follow up at an average 6.2 years after THA.

[Scorpio TS prosthesis in severe deformity and revision knee arthroplasty--preliminary report].

Authors present early results of Scorpio TS prosthesis in primary and revision total knee arthoplasty due to aseptic and septic loosening. 26 arthroplasties were performed on 25 patients. There were 19 women and 6 men of age from 37 to 80 (average 68.

[Conduct and tactics of infections after hip arthroplasty].

The number of arthroplasty surgeries is growing globally, bringing about an increase in the absolute number of infected complications. No precise statistics of complications are available in Poland. The present paper discusses the main causes of infected complications of hip arthroplasty.

[Modular short-stem prosthesis in total hip arthroplasty--preliminary report].

Total hip arthroplasty has become one of the most succesful procedure in orthopaedic surgery. More and more active, young patients undergo primary hip replacement. Bone stock preservation is crucial when performing THR in this group of patients.

Differential diagnosis of post-surgery scars and recurrent lumbar disc herniation in MRI.

Background. Spine MR had a significant progress on disc disease diagnosis, reasons of operative treatment failure, and reccurrence of pain.
The aim of the study was to estimate by the use of MRI the causes of pain among patient after discectomy, and to compare them with intraoperative findings.

MRI of the intervertebral disc in lumbar disc disease.

Background. MRI of the intervertebral disc in discopathy of the lumbar spine have been presented.
Material and methods.

Value of diagnostic methods in diagnosis of the disc disease.

Background. Injury of the intravertebral disc after precise clinical evaluation should be confirmed by different radiographic methods. Although diagnostic methods have recently progressed, there are still problems with proper diagnosis concerning the level of pain provocation.

Pain in the spine in the context of discopathy and degenerative changes, with particular attention to post-traumatic lesions.

Pain of the cervical spine is either directly or indirectly dependent on degenerative changes in the cervical dinks. Traumatic injury to the cervical spine may result in a cervical syndrome some years later as a result of degenerative changes. Cervical disk protrusuion or degenerative changes can be compared to a similar condition which occurs in the lumbar spine.

Outcome in the treatment of discopathy by interbody fusion with the posterior approach using metal cages.

Background. Discopathy most often occurs in persons from 20 to 50 years old, in the period of greatest physical and intellectual capacity, and thus poses a major social problem. The goal of our research was to evaluation the outcome of interbody fusion performed with metal cages.

Minimally invasive total hip arthroplasty--our clinical experience.

Background: Minimally invasive prosthetic hip surgery (MIS) attempts to minimise the extent of the operation. The aim of the study was to describe minimally invasive hip surgery and to present early clinical experience of the authors.

Material And Methods: 41 minimally invasive hip replacements through a posterior approach were carried out at the Orthopaedic Department of the Postgraduate Medical Education Centre in Otwock between 2004 and 2006.

[Neer classification of the proximal humerus fractures based on our own material].

Introduction: About 4-5% of all fractures are localised to the proximal end of the humerus. During the last 30 years a two-time increase has been observed. The cause was ageing of population and a higher incidence of fractures.

[Old and new materials in the hip prosthesis].

Since the second half of the XX century a steady evolution of hip prosthesis design is taking place. Implant shape, fixation systems and materials are constantly evolving. The paper presents the materials combinations most commonly used in hip prosthesis (metal-metal, metal-polyethylene and ceramic).

[Osteosarcoma of the lumbar spine--a case report].

Primary osteogenic sarcoma of the spine is a very rare tumor. A case of osteosarcoma of the lumbar spine in a 22-year-old man is presented. Diagnosis was obtained by an open biopsy.

[What's new in total hip replacement?].

The authors present special types of stems and acetabulum components. Analyzing the available the authors try to assess which parameters of the prosthesis influence long-term outcomes. "Wear and tear" of the implants was also analysed.

[Diagnostics and treatment of intervertebral disc herniation].

The paper reviews procedures for treatment of intervertebral disc herniation in our Department, evaluating modern scanning methods and surgical procedures. A total of 173 cases aged 13-73 years are presented. Discectomy was performed at surgery, with recent cases also embracing intervertebral spondylodesis with the use of cages to restore intervertebral distance.

[Results of treatment of unilateral sacralization of transverse process of the fifth lumbar vertebrae].

Pathology and symptomatology of unilateral sacralization of transverse process of the fifth lumbar vertebrae articulating with sacral and iliac bone is presented. Five patients (4 females, 1 male) aged 27-42 are reported. Symptoms included spinal pain, radicular pain, L4/L5 disc prolapse, and lumbar scoliosis.

[Thoracic outlet syndrome].

Results of surgical treatment for thoracic outlet syndrome in 7 patients are reviewed. The symptom has been caused by cervical rib in 5 cases, in 1 case by the first rib anomaly and in 1 case by disturbed attachment of m.scalenus anterior.

[Two cases of coexisting dysplasia fibrosa and mesenchymoma].

Two patients with dysplasia fibrosa who also had a tumor of mesenchymal origin are presented. One of them underwent one time resection of dysplasia fibrosa focus and the tumor, the other had the tumor resected 17 years after surgical resection of focus in the femur. The authors suggest an etiologic relationship between these two conditions based on mesenchymal changes--the occurrence never described previously.

[Complications of vertebral disc and spinal diseases after manipulation therapy].

Complications caused by manipulation therapy in 3 cases of spine condition and 22 cases of vertebral disc disease observed in relatively short period of time are presented. In the first instance the patients were not diagnosed by physician. In the second one in all cases the nucleus pulposus protruded under the anterior ligament or into the spinal canal.
