Subspine Hip Impingement: Clinical and Radiographic Results of its Arthroscopic Treatment.

 To evaluate the clinical and radiographic results as well as complications related to patients undergoing arthroscopic treatment of subspine hip impingement.  We retrospectively evaluated 25 patients (28 hips) who underwent arthroscopic treatment of subspine impingement between January 2012 and June 2018. The mean follow-up was 29.

Pelvic Bone Deformity and Its Correlation with Acetabular Center-edge Angle.

 The purpose of the present study was to evaluate the pelvic bone deformities and its correlation with the acetabular center-edge (CE) angle.  Between August 2014 and April 2015, we prospectively evaluated patients aged between 20 and 60 years old. The exclusion criteria were: metabolic disease, previous hip or spine surgery, radiograph showing hip arthrosis ≥ Tönnis two, severe hip dysplasia, global acetabular overcoverage, acetabular crossover sign, hip deformities from slipped capital femoral epiphysis (SCFE) or Leg-Perthes-Calveé, and bad quality radiographs.

Open versus arthroscopic approach in the treatment of femoroacetabular impingement: a case-control study with two-years follow up.

Objective: To compare clinical and imaging results and complications between patients treated for femoroacetabular impingement (FAI) who underwent either anterior open surgery or an arthroscopic approach, with a minimum follow-up of two years.

Methods: This retrospective case-control study included patients submitted to FAI surgical treatment between November 2007 and March 2012. Patients treated with open surgery were compared with those treated with arthroscopy.

Advantages and limitations of national arthroplasty registries. The need for multicenter registries: the Rempro-SBQ.

While the value of national arthroplasty registries (NAR) for quality improvement in total hip arthroplasty (THA) has already been widely reported, some methodological limitations associated with observational epidemiological studies that may interfere with the assessment of safety and efficacy of prosthetic implants have recently been described in the literature. Among the main limitations of NAR, the need for at least 80% compliance of all health institutions covered by the registry is emphasized; completeness equal or greater than 90% of all THA performed; restricted data collection; use of revision surgery as the sole criterion for outcome; and the inability of establishing a definite causal link with prosthetic dysfunction. The present article evaluates the advantages and limitations of NAR, in the light of current knowledge, which point to the need for a broader data collection and the use of more structured criteria for defining outcomes.

Arthroscopic Subcapital Realignment in Chronic and Stable Slipped Capital Femoral Epiphysis.

Stable slipped capital femoral epiphysis (SCFE) is the most common disease in the adolescent hip, with an estimated frequency of 10.8 in every 100,000 individuals. Recent studies of the biomechanics of femoroacetabular impingement indicate that small anatomical deformities of the hip arising from SCFE can potentially cause permanent acetabular chondral damage.

Arthroscopic subcapital realignment osteotomy in chronic and stable slipped capital femoral epiphysis: early results.

Objective: This study aimed to evaluate the clinical and radiographic outcomes, as well as the complications of arthroscopic subcapital realignment osteotomy in chronic and stable slipped capital femoral epiphysis (SCFE). As indicated by the literature review, this is the first time this type of arthroscopic osteotomy was described.

Methods: Between June 2012 and December 2014, seven patients were submitted to arthroscopic subcapital realignment osteotomy in chronic and stable SCFE.

Extracapsular approach for arthroscopic treatment of femoroacetabular impingement: clinical and radiographic results and complications.

Objectives: To evaluate the clinical and radiographic results and complications relating to patients undergoing arthroscopic treatment for femoroacetabular impingement by means of an extracapsular approach.

Methods: Between January 2011 and March 2012, 49 patients (50 hips) underwent arthroscopic treatment for femoroacetabular impingement, performed by the hip surgery team of the Orthopedic Hospital of Passo Fundo, Rio Grande do Sul. Forty patients (41 hips) fulfilled all the requirements for this study.

Prevalence of microbiological markers in bone tissue from live and cadaver donors in the musculoskeletal tissue bank of Passo Fundo.

Objective: To conduct an epidemiological analysis on the main microbiological markers in bone tissue that was processed at the musculoskeletal tissue bank of Hospital São Vicente de Paulo, in Passo Fundo, between August 2007 and October 2011.

Methods: Between August 2007 and October 2011, 202 musculoskeletal tissue samples were collected for the tissue bank. Among these, 159 samples were from living donor patients and 43 were from cadaver donors.

CIRCUMFERENTIAL PROXIMAL FEMORAL ALLOGRAFTS IN REVISION SURGERY ON TOTAL HIP ARTHROPLASTY: CASE REPORTS WITH A MINIMUM FOLLOW-UP OF 20 YEARS.

Among the options for femoral reconstruction in total hip arthroplasty (THA) revision procedures, in cases of extensive circumferential defects, is the use of proximal femoral allografts. This technique makes it possible to correct the hip abductor mechanism and the leg length discrepancy, as well as presenting osteoconductive potential. The authors report the clinical and radiographic results from two cases of THA revision using this technique, with a minimum follow-up of 20 years.

CIRCUMFERENTIAL PROXIMAL FEMORAL ALLOGRAFTS IN TOTAL HIP ARTHROPLASTY REVISION SURGERY.

Objective: To evaluate the clinical and radiographic results from patients who underwent femoral reconstruction secondary to loosening of total hip arthroplasty, using circumferential proximal femoral allografts and cemented implants.

Methods: A retrospective study was conducted on 32 patients (33 hips) who underwent femoral reconstruction secondary to loosening of total hip arthroplasty, using circumferential proximal femoral allografts and cemented implants. Among these patients, 28 (29 hips) fulfilled all the requirements for this study.
