Early results of revision acetabular cup using antiprotrusio reconstruction rings and allografts.

Background: Hip arthroplasty is one of the most frequently performed orthopedic procedures with high scores of success while its most common complication is aseptic loosening of the acetabular component, which may result from host bone loss or even from pelvis discontinuity. The purpose of the study was to evaluate results in patients after revision acetabular arthroplasty with reconstruction rings and allografts.

Materials And Methods: Retrospective data was collected from 69 revisions of acetabular components, performed in a group of 69 treated patients (the mean age 65.

[Clinical and metallographic evaluation of the causes of mechanical loosening of revision baskets Recon Ring--description of 3 cases].

Aim of this study is to assess the causes of mechanical loosening of revision Recon Ring baskets (Aesculap / BBrown, Germany). This analysis was done by assessing the circumstances of baskets loosening of revision in 3 patients. Intraoperative images and radiographs of patients with these clinical complications were analyzed, and removed damaged bins and bolts of revision metallographic expertise.

[Hip revision arthroplasty in massive bone loss of acetabulum with the use of reinforcement ring].

The aim of the study was the assessment of results after acetabular revision arthtoplasty with the use of reinforcement ring ReconShell (BBrown - Aesculap) and homogenous bone grafts. There were 49 patients in the study (42 women and 7 men) in the age from 30 to 88 years. The follow-up period ranged from 4 to 48 months.

[Use of bulky, femoral head allografts in revision hip arthroplasty for acetabular component aseptic loosening].

The aim of the study was to analyze results in patients treated with frozen, bulky femoral head allografts without reinforcement ring for significant bone lost after acetabular component aseptic loosening. Retrospective analysis was done on 19 patients in the average age of 58 years. There were 13 women in this group.

Evaluation of satisfaction with surgical treatment for musculoskeletal dysfunction in children with cerebral palsy.

Background: The variety of symptoms in cerebral palsy (CP) points to the advisability of using the term 'cerebral palsies' to underline the complex nature of the associated musculoskeletal dysfunctions. The incidence of CP is estimated at 1 to 5 in 1000 live born infants. This makes CP one of the main causes of hospitalization in paediatric orthopaedic wards.

Cementless hip joint alloplasty complicated by intraoperative fracture of the femoral bone.

Background: The aim of the study was to analyse the outcomes of hip replacement complicated by intraoperative femoral fractures and to analyse their effective management.

Materials And Methods: The medical records of 43 cases of intraoperative femoral fractures (1.4% of all hip replacements) were retrospectively reviewed.

[Derotational osteotomy of humerus in the treatment of children with persistent brachial plexus palsy].

Patients with persistent brachial plexus palsy, advanced secondary deformity of gleno-humeral joint and rigid adduction and internal rotation contracture are candidates for external derotation osteotomy of the humerus. The aim of the study was to analyze the clinical results of patients treated with humeral derotational osteotomy. The analysis was performed on 9 patients in the average age of 12.

[Elective total hip arthroplasty for patients 75 years of age and older].

The increasing life expectancies among octogerians ang nanogerians cause increased need for total hip replacement in this age group. The aim of our study was to analyze final results after total hip arthroplasty in patients 75 years of age and older. Clinical and radiological retrospective study was performed on a group of 59 patients (72 hips) in the mean age of 78 years.

Patellar height after barrel-vault high tibial osteotomy.

The purpose of the study was to assess the influence of barrel-vault high tibial osteotomy on patellar position and to evaluate the reliability and interobserver variability of three patellar height ratios. The radiographs of 24 knees that had undergone barrel-vault height tibial osteotomy with available preoperative as well as postoperative radiographs of the last follow-up were enrolled in the study. The patellar position was evaluated with the use of the Insall-Salvati, Blackbourne-Peel and Caton-Linclau methods.

[Treatment of physeal fractures in children].

The aim of the study was to determine final clinical and radiological results of epiphyseal fractures treated in our hospital. Thirty-five patients were included in the study (6 girls and 29 boys) aged from 5 to 17 years (mean 12.1 years).

[Operative treatment of Haglund's deformity].

The paper presents results of the operative treatment of 22 heel in 18 patients mostly young women from 13 to 31 years old (average 20.6) with Haglund's exostosis. Operative technique consisted in partial resection of the heel with removal of the Achilles bursa.

[Anterior cruciate ligament reconstruction by autogenous bone-patellar tendon-bone graft: correlation between bone-tunnel position and clinical results].

The authors evaluate correlation between bone-tunnel position and clinical results of 50 patients, aged 18-47 years, after anterior cruciate ligament reconstruction by bone-patellar tendon-bone autograft with half-tunnel technique. The evaluation comprises the femoral tunnel placement at the lateral femoral condyle, the angle of the tibial tunnel to the medial joint line of the tibia and paraarticular location of the tibial tunnel width clinical outcome within one to five years prior to operation. Bone-tunnel placement was based on radiograms done in anteroposterior and lateral view.

[Percutaneous trigger finger release].

Results of percutaneous release of the trigger finger in 18 patients (5 males and 13 females), 23-67 years old are presented. All in all, 26 fingers were operated, 10 of them was the thumb. The distribution of fingers following Quinnel was: grade I--4; grade II--12; grade III--7 and grade IV--3.
