Pelvic Pseudotumor Associated With a Ceramic Bearing Total Hip.

Pseudotumors have been well documented to occur most frequently in metal-metal bearing total hip arthroplasties and less frequently in metal-polyethylene bearings. There are few cases in the literature of pseudotumors occurring in ceramic-ceramic articulations. We report a case of a large pelvic pseudotumor in a patient with a ceramic-ceramic bearing articulation in a 67-year-old man.

MRI overestimates articular cartilage thickness and volume compared to synchrotron radiation phase-contrast imaging.

Accurate evaluation of morphological changes in articular cartilage are necessary for early detection of osteoarthritis (OA). 3T magnetic resonance imaging (MRI) has highly sensitive contrast resolution and is widely used clinically to detect OA. However, synchrotron radiation phase-contrast imaging computed tomography (SR-PCI) can also provide contrast to tissue interfaces that do not have sufficient absorption differences, with the added benefit of very high spatial resolution.

The physiopathology of osteoarthritis: Paleopathological implications of non-articular lesions from a modern surgical sample.

Objectives: This research focused on osteoarthritis (OA) lesions on modern patients to 1) identify consistently observed lesions not included within current paleopathological measures of OA, 2) assess the correspondence of bone and cartilage lesions with clinical OA diagnostic criteria, and 3) discuss the correspondence of bone lesions with sources of pain reported in clinical literature.

Materials: Tibial plateaus from 62 patients undergoing total knee replacement surgery due to OA were examined.

Methods: Plateaus were scored for several non-standard OA criteria, including non-articular and X-ray visible lesions and pre-maceration cartilage lesions, as well as articular surface criteria standard in paleopathology.

Primary Total Knee Arthroplasty: Correlation between Preoperative Radiographic Severity of Arthritis and Postoperative Patient Satisfaction.

Predicting postoperative outcomes following total knee arthroplasty (TKA) is important for patient selection. This study focuses on patient-reported outcomes and satisfaction in relation to preoperative radiographic arthritis severity. A retrospective chart review of 420 TKAs was performed.

Predictors of hip fractures and mortality in long-term care homes in Saskatchewan: Does vitamin D supplementation play a role?

High rates of hip fracture (HF) in long-term care (LTC) lead to increased hospitalization and greater risk of death. Supplementation of residents with vitamin D3 (vitD) has been recommended, but may be infrequently acted upon. Using a prospective cohort design, we explored use of vitD at doses ≥800 IU for hip fractures (HF) and for mortality among permanent LTC residents in Saskatchewan between 2008 and 2012, using provincial administrative health databases (N = 23178).

The Incidence of Hip Fractures in Long-Term Care Homes in Saskatchewan from 2008 to 2012: an Analysis of Provincial Administrative Databases.

Background: Hip fractures (HFs) represent an important cause of morbidity and mortality among adults in long-term care (LTC), but lack of detailed epidemiological data poses challenges to intervention planning. We aimed to determine the incidence of HFs among permanent LTC residents in Saskatchewan between 2008 and 2012, using linked, provincial administrative health databases, exploring associations between outcomes and basic individual and institutional characteristics.

Methods: We utilized the Ministry of Health databases to select HF cases based on ICD 10 diagnoses fracture of head and neck of femur, pertrochanteric fracture and subtrochanteric fracture of femur.

Posterior fracture dislocation of the ankle: technique and clinical experience using a posteromedial surgical approach.

Objective: The purpose of this study is to revisit the posteromedial surgical approach to the ankle and report the clinical outcomes of this technique in a cohort of 17 patients.

Design: Retrospective.

Setting: Level I trauma center.

Missed acute isolated peroneal compartment syndrome.

This paper outlines 3 cases of acute isolated peroneal (lateral) compartment syndrome following exertion, minor trauma or overuse. Compartment syndromes are usually associated with crush injuries or fractures; they are an uncommon development following minor trauma or overuse. In acute isolated peroneal compartment syndrome the diagnosis is often delayed, resulting in permanent impairment.

Failure of a new constrained acetabular insert: a report of 2 cases.

A new constrained total hip arthroplasty (THA) is currently in use. We report on one patient with 2 failed Trilogy constrained acetabular liners in the same hip (Zimmer, Warsaw, IN). We are not aware of any other published reports concerning failure of this implant.
