Felix Stief, André Schmidt, Stefan van Drongelen, Katharina Lenarz, Dara Froemel, Timur Tarhan, Frederick Lutz, Andrea Meurer
A total hip replacement (THR) is a common and routine procedure to reduce pain and restore normal activity. Gait analysis can provide insights into functional characteristics and dynamic joint loading situation not identifiable by clinical examination or static radiographic measures. The present prospective longitudinal study tested whether two years after surgery a THR would restore dynamic loading of the knee and hip joints in the frontal plane to normal. Instrumented gait analysis was performed shortly before surgery and approximately two years after THR on 15 unilateral hip osteoarthritis patients...

Sotos syndrome is a rare congenital syndrome caused by deletions or mutations in the NSD1 gene (chromosome 5q35) which results in overgrowth. A wide range of manifestations may result in unexpected and/or early death, including congenital cardiac malformations and tumours, epilepsy, intra-tumoural haemorrhage or embolism and bleeding diatheses. A case of lethal pulmonary fat embolism complicating revision of a left total hip replacement following spontaneous fracture is reported in a 39-year-old man with Sotos syndrome...

BACKGROUND: Under the Merit-based Incentive Payment System, physician payment will be adjusted using a composite performance score that has 4 components, one of which is resource use. The objective of this exploratory study is to quantify the facility-level variation in surgical case duration for common surgeries to examine the feasibility of using surgical case duration as a performance metric. METHODS: We used data from the National Anesthesia Clinical Outcomes Registry on 404,987 adult patients undergoing one of 6 general surgical or orthopedic procedures: laparoscopic appendectomy, laparoscopic cholecystectomy, laparoscopic cholecystectomy with intraoperative cholangiogram, knee arthroscopy, laminectomy, and total hip replacement...

A crutch is prescribed to permit the patient to walk safely and independently immediately after total hip replacement (THR) surgery. Purpose of this study is to evaluate the influence of the crutch setup on upper limbs biomechanics, including shoulder joint kinematics and kinetics parameters that will be evaluated to detect possible differences related to the crutch length. Thirty patients were randomly assigned to elbow flexed (EF) or elbow extended (EE) forearm crutch setup. Subjects were asked to walk on the laboratory path, instrumented with motion tracking system and force platforms...

BACKGROUND: More than 75,000 total hip replacements were performed in England and Wales in 2014, and this figure is predicted to increase. Trends in mortality and complications following total hip replacement from 2005 to 2014 were evaluated to quantify risk and to identify "at-risk" groups to better inform recommendations for patient care. METHODS: Our primary analysis estimated 90-day inpatient mortality following total hip replacement using Hospital Episode Statistics data from 2005 to 2014...

Understanding trends in reimbursement is critical to the financial sustainability of orthopedic practices. Little research has examined physician fee trends over time for orthopedic procedures. This study evaluated trends in Medicare reimbursements for orthopedic surgical procedures. The Medicare Physician Fee Schedule was examined for Current Procedural Terminology code values for the most common orthopedic and nonorthopedic procedures between 2000 and 2016. Prices were adjusted for inflation to 2016-dollar values...

BACKGROUND: The use of Ceramic-on-Ceramic (CoC) bearings in primary total hip arthroplasty (THA) is increasing and has been intensively analysed. This bearing plays a particularly relevant role in young, active patients and shows advantages over other bearings in biocompatibility, wear rate and lubrication properties. On the contrary, CoC bearings in revision THA are seldom used and scarcely analysed. The aim of this study is to systematically review the available literature on CoC bearings in revision THA...

The rate of periprosthetic femoral fractures following total hip replacement has been growing steadily in the last 20 years and ranges from 0.1% to 2.1%. These fractures are mostly related to older patients with the presence of chronic diseases and frequently poor bone quality. The treatment is surgically very complex and demanding, followed by a series of complications. The evaluation in this retrospective study included 23 patients who were medically treated from January 2004 to December 2015 with the mean follow-up of 14...

OBJECTIVES: To describe a stepwise process to obtain fused images from micro-computed tomography (μCT) and histological images of bone specimens. MATERIAL AND METHODS: Four surgically resected human femoral heads from four patients who had total hip replacement were imaged at a spatial resolution of 12-microns by using μCT. Histological sections of four focal bone lesions including bone cyst in osteoarthritis (n=2) and subchondral bone plate fracture in osteonecrosis (n=2) were prepared and digitized...

BACKGROUND: Efforts to reduce racial disparities in total hip replacement (THR) have focused mainly on patient behaviors. While these efforts are no doubt important, they ignore the potentially important role of provider- and system-level factors, which may be easier to modify. We aimed to determine whether the patterns of interaction among physicians around THR episodes differ in communities with low versus high concentrations of black residents. MATERIALS AND METHODS: We analyzed national Medicare claims from 2008 to 2011, identifying all fee-for-service beneficiaries who underwent THR...

Sealed osteons are unusual variants of secondary osteons that have received little attention, especially in non-human bones. Sealed osteons are characterized by central canals that are plugged with bone tissue. As with other variants of secondary osteons (e.g. drifting, dumbbell, multi-canal), understanding how and why sealed osteons form can shed light on the mechanisms that regulate normal bone remodeling and how this process can be perturbed with aging and some diseases. In a recent microscopic evaluation of human tibiae obtained after traumatic amputations, 4-5% of the osteons were sealed...

Background and purpose - The best treatment option for severe slipped capital femoral epiphysis (SCFE) is still controversial. We compared clinical and radiographic outcomes of modified Dunn procedure (D) and in situ fixation (S) in severe SCFE. Patients and methods - We retrospectively compared D and S, used for severe stable SCFE (posterior sloping angle (PSA) > 50°) in 29 patients (15 D; 14 S). Propensity analysis and inverse probability of treatment weights (IPTW) to adjust for baseline differences were performed...

BACKGROUND: Total hip replacements (THRs) are the sixth most common surgical procedure performed in the USA. Readmission rates are estimated at between 4.0 and 10.9%, and mean costs are between $10,000 and $19,000. Readmissions are influenced by the quality of care received. We sought to examine differences in readmissions by insurance payer, race and ethnicity, and income status. METHODS: We analyzed all THRs from 2007 to 2011 in California, Florida, and New York from the State Inpatient Databases, Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality...

Background: Hospitals may be under pressure to implement cost saving strategies regarding prosthesis choice. This may involve the use of components which are not the first preference of individual surgeons, or those they have little experience with. We aim to examine the effect of standardizing the type of femoral stem used in a single trust, and determine whether this is safe practice, particularly in those who have never used this particular stem before. Methods: We report results at 2 years of 151 primary total hip arthroplasties performed using a single femoral stem...

BACKGROUND AIMS: Bone marrow mesenchymal stromal cells (MSCs) are an appealing source for several cell-based therapies. Many bioreactors, such as the Quantum Cell Expansion System, have been developed to generate a large number of MSCs under Good Manufacturing Practice conditions by using human platelet lysate (HPL). Previously, we isolated a novel cell population in human bone marrow, mesodermal progenitor cells (MPCs), which we identified as precursors of MSCs. MPCs may represent an important cell source for regenerative medicine applications...
