Surgical Approach and Hip Laterality Affect Accuracy of Acetabular Component Placement in Primary Total Hip Arthroplasty.

Surgical Approach and Hip Laterality Affect Accuracy of Acetabular Component Placement in Primary Total Hip Arthroplasty. Surg Technol Int. 2019 Sep 16;35: Authors: Crawford DA, Adams JB, Hobbs GR, Lombardi AJV, Berend KR Abstract INTRODUCTION: Controversy remains if the anterior approach improves acetabular component alignment, and many studies have compared approaches with different surgeons over different timeframes. The purpose of this study was to assess a single surgeon's experience over a one-year timeframe and radiographically compare acetabular component positioning with the direct anterior versus direct lateral approach. Secondarily, this study compares acetabular component position differences between right and left hips for a right-hand dominant surgeon. MATERIALS AND METHODS: Postoperative radiographs of 289 primary total hip arthroplasties (THAs) performed by a single right-hand dominant surgeon in 2014 were reviewed for abduction, anteversion, and medial cup seating. Component position was compared to surgical approach with 152 direct anterior (DA) THAs (53%) and 137 direct lateral (DL) THAs (47%). The operative side was also compared to surgeon hand dominance. Surgeons target was 40° abduction, 20° anteversion ±5°, and seating to the teardrop ±5mm. Lewinnek target was also assessed. RESULTS: DA hips had a significantly lower abduction angle (p=0.04), less abduction target outliers (p

This article reports segmental absence of tracheal cartilage rings in a kitten. An 8-month-old female kitten was presented with a history of weight loss and respiratory distress for 2 months. Radiographs of the thorax demonstrated a large air-filled sac suggestive of pneumomediastinum. No cartilaginous structures were evident radiographically over the caudal portion of the trachea. At necropsy examination, approximately 2 cm from the carina, a 3 cm segment of the trachea lacked cartilaginous rings. The clinical and morphological features of this lesion were similar to those described in human and canine cases of ...

AbstractPurposeThe purposes of this study were to investigate the anatomical risk factors of grade 3  J-sign and analyse the influence of J-sign grades on the short-term clinical outcomes of patients with recurrent patellar dislocation.MethodsFrom 2016 to 2018, a total of 168 patients with recurrent patellar dislocation (187 knees) underwent medial patellofemoral ligament reconstruction with or without tibial tuberosity medialization. Pre-operative J-sign severity was graded according to a previously described classification (grades 1 –3). Potential anatomical risk factors of J-sign were explored. Comparisons we...

ConclusionTE interfaced with ultrasound in this hybrid machine presents no learning curve effect. After a short initial training session, a novice observer is able to perform high rates of reliable and very reliable TE measurements.Key Points• When performing liver stiffness measurements using a new hybrid machine composed of transient elastography interfaced with ultrasound, the rate of failures of measurements is very low, below 5%.• After a short training session and using ultrasound planning, a novice operator, whatever its expertise in ultrasound imaging, is capable of performing high rates of reliable and v...

Conclusions: The Schneiderian membrane thickness was positively and highly associated with gingival biotype. The gingival biotype and arch form had significant effect on Schneiderian membrane thickness and can provide valuable clinical information on Schneiderian membrane thickness preoperatively for implant placement and sinus lift procedures.

Publication date: Available online 13 October 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): Angelica Patino Gonzalez, Lucy Modahl, Daniel KowalAbstractImaging plays a central role in the diagnosis of pulmonary infections with the chest radiograph as the initial study of choice. CT can further delineate the extent of disease and present key imaging signs that, along with clinical history and laboratory data, can properly guide the differential diagnosis. In this article, we review and illustrate the most relevant CT imaging manifestations of common and less common pulmonary infections, including a section devoted...
