Bone Quality Assessment Before Total Hip Arthroplasty: The Role of Densitometry.

Background Total hip arthroplasty (THA) is effective in the treatment of hip osteoarthritis. Radiographic evaluation, standard in THA planning, is sufficient in examining hip anatomy, although it may not precisely assess bone quality. A routinely implemented method in bone quality assessment is densitometry.

Assessment of the Length of the Pedicle of the Anterolateral Thigh Flap.

Purpose To estimate the length of the pedicle of the anterolateral thigh flap (ALT) and to assess how this length corresponds with the distances between the anatomical landmarks. Methods The study group consisted of patients who underwent computed tomography angiograms ranging minimally from the anterior superior iliac spine (ASIS) superiorly and tibia inferiorly. In the study we included 44 patients.

Corrective Osteotomies in Severe Non-Idiopathic Lower Limb Alignment Disorders in the Aspect of Future Joint Endoprosthesis-A Perspective Study.

The aim of this study was to retrospectively evaluate the effectiveness of corrective osteotomies in lower limb axis disorders at different levels of non-idiopathic (post traumatic, developmental, post-septic) etiology. A total of 50 patients were divided into three groups: A-thigh segment alignment disorder (24 patients); B-tibia segment alignment disorder (18 patients); C-thigh and tibia segment alignment disorder (8 patients). Radiological evaluation of digital lower limb postural X-ray was performed laterally and for AP, and included mLPFA, mLDFA, MAD, CORA coronal and sagittal plane parameters for the femur segment and mMPTA, mLDTA, MAD, CORA coronal and sagittal plane for the tibia segment.

Radiologic Predictors for Clinical Improvement in PAO-A Perspective Study.

The aim of this study was to evaluate the results of surgical treatment of developmental dysplasia of the hip (DDH) with periacetabular osteotomy (PAO) and determine the values of radiological parameters that would allow us to obtain an optimal clinical result. Radiological evaluation included determining the center-edge angle (CEA), medialization, distalization, femoral head coverage (FHC), and ilioischial angle as measured on a standardized AP radiograph of the hip joints. Clinical evaluation was based on the HHS, WOMAC, Merle d'Aubigne-Postel scales and Hip Lag Sign.

Assessment of the endoprosthesis offset in a dysplastic coxarthrosis.

Incorrectly developed acetabulum and subluxated hip joint may cause many problems for proper implantation of endoprosthesis. The aim of this work is to assess the radiological results of offset restoration and selection of endoprosthesis implant in a dysplastic hip joint. The study group consisted of patients who had a surgery in the period between 2016 and 2018.

Minimally Invasive Radiographic Evaluation of the Dysplastic Hip Joint Configuration in Terms of Surgical Treatment with Hip Preservation by PAO.

Introduction: Residual developmental dysplasia of hip (RDDH) is a factor of early osteoarthritis of the hip. The main problems are pain and instability of the hip joint due to inadequate coverage of the femoral head by the acetabulum. The purpose of this study was to radiologically evaluate RDDH after Bernese periacetabular osteotomy (PAO) and to compare RDDH to healthy hips.

Hip dysplasia in adolescence: osteotomy in childhood improves the results of periacetabular osteotomy in adolescents and young adults : a prospective study.

Aims: Developmental dysplasia of the hip (DDH) describes a pathological relationship between the femoral head and acetabulum. Periacetabular osteotomy (PAO) may be used to treat this condition. The aim of this study was to evaluate the results of PAO in adolescents and adults with persistent DDH.

Difficulties in Treating Complex Knee Injuries with Fracture of Posterior Tibial Plateau.

Background: The aim of the study was to assess the outcomes of surgical treatment of complex knee injuries with a posterior inverted-L approach to the knee joint.

Material And Methods: The study retrospectively enrolled 13 patients who underwent surgical treatment due to knee injuries with posterior tibial plateau fractures in 2015-2017. Pre-operative planning was based on antero-po-sterior and lateral X-rays and CT images.
