Impact of external beam radiation on total shoulder arthroplasty outcomes: a propensity-matched cohort study.
External beam radiation therapy has a number of deleterious effects on the body, and a number of post-operative complications have been reported for several surgeries including total knee arthroplasty. However, few studies have investigated the impact of external beam radiation therapy for total shoulder arthroplasty (TSA). Our study aimed to assess the systemic and joint complications associated with TSA in patients with prior radiation exposures, as well as evaluate the surgical outcomes of radiation patients compared to non-radiation TSA patients. ⋯ Patients with prior history of external beam radiation undergoing TSA had a higher risk of systemic complications and prosthetic joint infection compared to patients without a prior history. These complications suggest a more complicated post-operative management course for these patients.

An isoelastic monoblock cup versus a modular metal-back cup: a matched-pair analysis of clinical and radiological results using Einzel-Bild-Röntgen-Analyse software.
Bone preservation and long-term survival are the main challenges in cementless total hip arthroplasty (THA). A good bone stock is especially important for adequate anchorage of the cup in revision cases. However, the optimal acetabular cup design for preserving good bone stock is still unclear. We aimed to compare clinical outcome, radiological alterations, migration, and wear at mid-term for two different cup types. ⋯ The isoelastic press-fit monoblock VEPE cup and modular metal-back HXLPE cup showed equivalent mid-term wear and cup migration. Long-term studies are required to determine the effects of modularity, isoelasticity, and polyethylene stabilization with vitamin E on cup loosening and survival rates.

Validity of leg length measurement in the supine and standing position compared with pelvic survey X-ray after total hip arthroplasty.
The correct adjustment of leg length is a major goal in the implantation of total hip replacements (THRs). Differences in leg length can lead to functional impairment and patient dissatisfaction. By determining leg length at an early stage, before the patient is discharged from hospital, compensatory measures such as the production of special insoles or orthopaedic footwear can be initiated promptly if there is a difference in leg length. Due to shortening of the period of time spent in hospital, the traditional measurement of leg length in a standing position may be increasingly subject to error. A protective posture immediately after surgery or the presence of a twisted pelvis, for example, due to scoliotic spinal misalignments, falsifies the measurement result in the standing position. Here, the measurement of leg length in the supine position may prove to be accurate immediately postoperatively, regardless of potential sources of error, and is to be compared with measurement in the standing position versus radiological measurement on the AP pelvic survey. ⋯ It is shown that the postoperative measurement of LLD in the supine and standing position is equally valid and sufficiently accurate, compared with the gold standard of measurement on a radiograph.

Periprosthetic fracture following anterior approach or dislocation after posterior approach: which one is the lesser evil?
The most common approaches in total hip arthroplasty (THA) have different complication profiles; anterior-approach (AA-THA) has an increased risk of periprosthetic fractures (PPF); posterior-approach (PA-THA) is associated with higher dislocation risk. However, the relative severity of one versus the other is unknown. This study aims to compare outcome of patients who suffered PPF after AA-THA with those that sustained dislocation after PA-THA. ⋯ III, case-control study.

Complications following single-stage bilateral total knee arthroplasty and unilateral procedures: experience of a high-volume community hospital.
The safety of single-stage bilateral total knee arthroplasty (SSBTKA) compared to unilateral total knee arthroplasty (TKA) remains controversial. The present study compares the 90-day postoperative complications encountered following SSBTKA and unilateral TKA in an unselected cohort of patients performed at a high-volume community hospital. ⋯ SSBTKA did not result in greater complications when compared to unilateral TKA in this particular cohort. As expected, transfusion rates will likely be higher and there will be a greater need for acute inpatient care following surgery for SSBTKA patients.
