Mid-term results of total hip arthroplasty with anatomical ultra-short cementless stem in patients with developmental dysplasia of the hip Crowe type II.

The aim of this study was to present the mid-term results of ultra-short cementless stem total hip arthroplasty (THA) in patients with Crowe type II developmental dysplasia of the hip. The study consists of 68 patients (75 THAs) with a Proxima stem implanted between 2006 and 2015. The clinical results include Harris Hip Scores.

Dynamic hip screw in proximal femoral fractures followed by "single-stage" hip arthroplasty-retrospective analysis.

The aim of this study is to present the results of single-stage total hip arthroplasty (THA) after Dynamic Hip Screw (DHS) failure, or secondary posttraumatic osteoarthrosis. From 2003 to 2020, 15 THAs were performed in group of 15 patients for the treatment of DHS failure, or for late complications following femoral neck and pertrochanteric fractures. The mean follow-up period after arthroplasty was 46.

Ultra-short cementless anatomical stem for intracapsular femoral neck fractures in patients younger than 60 years.

The aim of this study was to present the midterm results of total hip arthroplasty with ultra-short anatomical cementless stem in the primary treatment of displaced intracapsular femoral neck fractures in patients younger 60 years. From 2006 to 2015, 17 hip arthroplasties (with the Proxima stem) were performed in group of 17 patients for the treatment of acute femoral neck fractures Garden type III and IV. The mean follow-up period was 112.

Total hip arthroplasty with ultra-short uncemented stem in patients with osteonecrosis of the femoral head: mid-term results.

Background: Mid-term results (clinical and radiographic) of ultra-short anatomical cementless stem total hip arthroplasty (THA) in patients with osteonecrosis of the femoral head (ONFH) has not often been presented. The aim of this study is to evaluate THA using the Proxima stem in patients with ONFH in the mid-term.

Methods: The study consists of 73 patients (97 THAs) with a Proxima stem implanted between 2006 and 2015.

Complex open elbow fracture Gustilo-Anderson type IIIB treated with the primary elbow arthroplasty: A case report.

Total elbow arthroplasty as a treatment option for open elbow fracture is relatively rare described. We reported a 39 years old polytrauma patient with complex open elbow fracture (Gustilo-Anderson type IIIB). The patient presented with large soft tissues defect on dorsal part of the left elbow, ulnar palsy due to the irreparable loss of the ulnar nerve, distal triceps loss due to the complete loss of the olecranon, loss of both humeral condyles with collateral ligaments and complex elbow instability.

Bunionette deformity corrected with "shortening" scarf osteotomy of the fifth metatarsal: mid-term results of a 34-cases.

Background: The aim of this study was to evaluate the clinical and radiological outcomes (in mid-term) after "shortening" scarf osteotomy of the fifth metatarsal for the treatment of bunionette deformity.

Methods: We retrospectively reviewed the functional score - American Orthopaedic Foot and Ankle Society (AOFAS) Lesser Toe Metatarsophalangeal-Interphalangeal Scale, radiographic results - 4th/5th intermetatarsal angle, varus angle of the 5th metatarsophalangeal joint and complications in a consecutive series of 34 feet (27 patients) with bunionette. Nine males and 18 females (mean age: 45 years) were included in the study.

Cementless hip arthroplasty and transverse shortening femoral osteotomy with the S-ROM stem for Crowe type IV developmental dysplasia.

Introduction: The aim of this study has been to present outcomes after cementless arthroplasty for developmental dysplasia Crowe type IV of the hip, with transverse subtrochanteric shortening osteotomy and using the S-ROM stem.

Methods: We evaluated radiographs, functional scores and complications in a consecutive series of 23 patients (28 hips) with high dislocation of the hip. The average age of patients at surgery was 49.

Fatigue failure of the sliding hip screw - clinical and biomechanical analysis.

The study was aimed at the clinical and biomechanical analyses of the sliding hip screw breakage with the use of finite element method. We have identified two patients with the sliding screw breakage. In the first patient, the biomechanical analysis revealed the reduced stress values σ not exceeding the yield limit or strength limit of the implant.
