Evaluation of Safety and Efficacy of Traction, Closed Reduction, and Subsequent Hip Fixation in Hilgenreiner Brace in Patients with Severe Forms of Hip Developmental Dysplasia.

Background: Hilgenreiner brace (Hb) was developed to improve hip reduction rate and reduce the incidence of femoral head avascular necrosis (AVN). In children under the age of 18 months with unstable hip joints or a dislocated hip joint, the treatment method involves nonsurgical treatment in most cases.

Objectives: To evaluate the effectiveness and safety of traction, closed reduction, and hip fixation in Hb in patients with severe forms of hip developmental dysplasia (DDH) in follow-up.

[Long-Term Results of Computer-Navigated Total Knee Arthroplasties Performed by Low-Volume and Less Experienced Surgeon].

PURPOSE OF THE STUDY The study aims to evaluate the long-term results of computer-navigated total knee arthroplasties performed by less experienced surgeon performing a small number of procedures per year. MATERIAL AND METHODS In the prospective randomised study functional and radiological results, rate of revision and probability of clinical and radiological survival were compared in 30 computer-navigated (in 28 patients: 19 women, 9 men, with the mean age of 66.9 years) and 31 conventionally implanted (in 30 patients: 27 women, 3 men, with the mean age of 66.

Comparison of intravenous and intra-articular tranexamic acid in reducing blood loss in primary total knee replacement.

Objectives: This study aims to compare the efficacy and safety of intra-articular tranexamic acid (TA) versus intravenous (IV) TA in the reduction of perioperative blood loss and the degree of early postoperative complications associated with primary unilateral cemented total knee replacement.

Patients And Methods: This prospective randomized study included 90 patients (36 males, 54 females; mean age 68.7 years; range 47 to 82 years) with knee osteoarthritis undergoing a unilateral cemented total knee replacement.

[Bone Remodelling in the Proximal Femur after Uncemented Total Hip Arthroplasty in Patients with Osteoporosis].

Purpose Of The Study: The aim of the study was to investigate the involvement of osteoporosis during remodelling of the proximal femur after uncemented total hip arthroplasty (THA) and the effect of bisphospohonate treatment on these changes.

Material And Methods: Sixty evaluated patients with non-cemented THA were divided into three groups on the basis of pre-operative densitometric examinations. Group 1 (15 patients with osteoporosis) received a single dose of 5 mg zoledronic acid in infusion during the second post-operative week.

[The incidence of osteopenia and osteoporosis in patients with cementless total hip arthroplasty].

Purpose Of The Study: The aim of the study was to evaluate the incidence of osteopenia and osteoporosis in the patients elected to cementless total hip replacement.

Material And Methods: The group evaluated comprised 100 patients with primary or secondary forms of coxarthrosis who underwent cementless total hip arthroplasty (THA). The results of densitometric examination of the lumbar spine and proximal femur were analysed.
