Risk Factors for Postoperative Deep Venous Thrombosis and Pulmonary Embolism Following Primary Total Hip Arthroplasty and Primary Total Knee Arthroplasty.

Pulmonary embolism (PE) and deep vein thrombosis (DVT) are common postoperative complications. This study retrospectively analyzes preoperative attributes as risk factors for DVT or PE following primary total hip arthroplasty (THA) and total knee arthroplasty (TKA). Preoperative transfusion, age 65+, dyspnea with moderate exertion, body mass index (BMI) 24.

Increased actual sling wear is associated with better early patient-reported and image-based outcomes after shoulder surgery.

Background: Prior studies have failed to show differences in functional outcomes for patient-reported sling use after rotator cuff repair. Temperature-sensing devices are used to more accurately measure brace adherence. The purposes of this study were to quantify actual sling adherence and its predictors and to establish whether increased sling adherence is associated with improved functional and image-based outcomes.

Risk Factors for Wound Complication following Primary Total Hip Arthroplasty.

This study assessed the National Surgical Quality Improvement Program (NSQIP), which provides data on 30-day post-operative complications from 500+ institutions, to identify risk factors for wound complications in patients undergoing primary total hip arthroplasty (THA). Patients undergoing primary THA between 2010-2017 were retrospectively reviewed. Patients experiencing post-operative wound complications were stratified based on pre-operative characteristics.

Hand size affects branching of the deep ulnar nerve and deep palmar arch.

Purpose: Understanding the anatomy of the deep neurovascular structures of the hand is essential in surgical planning. There is a lack of literature regarding hand size and its influence in branching variation and the distances between branches of various neurovascular structures. Our study quantifies the variation in branching distances of the deep ulnar nerve and deep palmar arch branches.

Effects of pelvic obliquity and limb position on radiographic leg length discrepancy measurement: a Sawbones model.

Purpose: Potential sources of inaccuracy in leg length discrepancy (LLD) measurements commonly arise due to postural malalignment during radiograph acquisition. Preoperative planning techniques for total hip arthroplasty (THA) are particularly susceptible to this inaccuracy, as they often rely solely on radiographic assessments. Owing to the extensive variety of pathologies that are associated with LLD, an understanding of the influence of malpositioning on LLD measurement is crucial.

Unplanned intubation after total hip and total knee arthroplasty: Assessing preoperative risk factors.

Objective: The purpose of this study is to assess preoperative patient attributes as risk factors for unplanned intubation after primary total knee and total hip arthroplasty.

Methods: This was a retrospective analysis of data collected from the National Surgical Quality Improvement Program (NSQIP) database. Patients undergoing Total Hip Arthroplasty (THA) or Total Knee Arthroplasty (TKA) who experienced postoperative intubation were included in the study.

Preoperative risk factors for postoperative pneumonia following primary Total Hip and Knee Arthroplasty.

Background: The purpose of this study is to evaluate risk factors for pneumonia following THA and TKA.

Methods: Patients were identified from the American College of Surgeons National Quality Improvement Database (NSQIP) who experienced postoperative pneumonia after undergoing primary THA and TKA.

Results: Many characteristics including old age, anemia, diabetes, cardiac comorbidities, dialysis, and smoking were independent risk factors for postoperative pneumonia after THA or TKA.

Readability Level of English and Spanish Orthopaedic Patient Education Materials English and Spanish Patient Education.

There are 16 million Hispanic people in the United States who rely on Spanish as their only effective method of communication. However, there is a scarcity of literature evaluating if patient education resources in Spanish meet the average American reading level or National Institute of Health (NIH) and American Medical Association (AMA) grade-level recommendations, especially in the field of orthopaedics. Representative orthopaedic search terms were input into Google and ten articles pertaining to patient education were selected.

An accurate method of measuring shoulder sling compliance: a validation study.

Background: The effect of postoperative shoulder sling compliance on surgical outcomes is unknown. The goal was to determine an accurate method to measure sling compliance. We compared volunteer recorded sling wear time with temperature-based sensors to monitor sling compliance.

Preoperative risk factors for postoperative cardiac arrest following primary total hip and knee arthroplasty: A large database study.

Background: Cardiac arrest (CA) has been identified as a potential complication following Total Hip Arthroplasty (THA) and Total Knee Arthroplasty (TKA). This retrospective, case-controlled study aims to identify risk factors in order to improve the management of patients undergoing THA or TKA with known preoperative comorbidities.

Methods: CPT codes were used to investigate the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database for patients who underwent THA or TKA from 2010 to 2017.

Changes in femoral offset is not associated with increased incidence of lateral hip pain following total hip arthroplasty.

Purpose: Increased femoral offset following total hip arthroplasty allows for greater stability of the hip joint. However, the increase in femoral offset can cause an impingement of local structures resulting in persistent lateral hip pain. There is conflicting evidence whether changes in femoral offset increases the rates of lateral hip pain following total hip arthroplasty.

Biomechanics in an Incomplete Versus Complete Supraspinatus Tear: A Cadaveric Study.

Background: Degenerative and traumatic changes to the rotator cuff can result in massive and irreparable rotator cuff tears (RCTs).

Purpose/hypothesis: The study objective was to conduct a biomechanical comparison between a small, incomplete RCT and a large, complete RCT. We hypothesized that the incomplete supraspinatus (SS) tear would lead to an incremental loss of abduction force and preserve vertical position of the humeral head, while a complete SS tear would cause superior humeral migration, decrease functional deltoid abduction force, and increase passive range of motion (ROM).

Long-Term Postoperative Total Knee Arthroplasty Flexion Scores in Relation to Body Mass Index.

Knee range of motion (ROM) is an important postoperative measure of total knee arthroplasty (TKA). There is conflicting literature whether patients who are obese have worse absolute ROM outcomes than patients who are not obese. This study analyzed whether preoperative body mass index (BMI) influences knee ROM after patients' primary TKA.

Beyond the dermis-high-risk invasive squamous cell carcinoma: a retrospective review.

Objective: Most cutaneous squamous cell carcinomas (cSCC) are low risk and can be treated with simple excision or ablation. High-risk cSCC require invasive treatment, including radical surgery. We present our experience in treating invasive cSCC of the pelvis and extremities.

Histological Assessment of Wallerian Degeneration of the Rat Tibial Nerve Following Crush and Transection Injuries.

Background:  Wallerian degeneration (WD) following peripheral nerve injury (PNI) is an area of growing focus for pharmacological developments. Clinically, WD presents challenges in achieving full functional recovery following PNI, as prolonged denervation of distal tissues for an extended period of time can irreversibly destabilize sensory and motor targets with secondary tissue atrophy. Our objective is to improve upon histological assessments of WD.

Evaluation of preoperative pain in patients undergoing shoulder surgery using the PROMIS pain interference computer-adaptive test.

Objective: The purpose of this study was to evaluate the Patient Reported Outcomes Measurement Information System (PROMIS) computerized adaptive testing Pain Interference (PROMIS PI) item bank in patients undergoing shoulder surgery. We hypothesized that PROMIS PI would exhibit a strong positive correlation with the numerical pain scale for the operative shoulder (shoulder NPS) with less floor and ceiling effects. Secondary study aims included assessing the relationships between patient characteristics and PROMIS PI.

Chronic Corticosteroid Use as a Risk Factor for Perioperative Complications in Patients Undergoing Total Joint Arthroplasty.

Background: Osteoarthritis may be caused by or concurrent with diseases such as rheumatoid arthritis or systemic lupus erythematosus, which rely on chronic corticosteroids regimens for treatment. If a total knee or hip arthroplasty is needed, this chronic treatment method has been associated with poorer surgical outcomes.

Methods: A retrospective analysis of data collected by the American College of Surgeons National Surgical Quality Improvement Program was conducted.

Biomechanical effects of superior capsular reconstruction in a rotator cuff-deficient shoulder: a cadaveric study.

Background: Superior capsular reconstruction (SCR) has been gaining popularity as a treatment for irreparable rotator cuff tears (RCTs), especially in younger patients. This biomechanical study aimed to investigate how SCR affects functional abduction force, humeral head migration, and passive range of motion following an irreparable RCT. We hypothesized that SCR will restore these parameters to nearly intact shoulder levels.

The biomechanics of the supraspinatus-deficient shoulder treated with superior capsular reconstruction vs. reverse total shoulder arthroplasty-experimental study.

Aim Of The Study: Our objective was to compare biomechanical effects of superior capsular reconstruction (SCR) and reverse total shoulder arthroplasty (rTSA) on shoulder motion, in the setting of an irreparable supraspinatus (SS) tear. We hypothesized that rTSA would produce greater improvement in abduction force and shift the humerus inferiorly, while SCR would produce greater range of motion (ROM) and prevent superior migration of the humerus during abduction.

Methods: Six cadaveric shoulders were evaluated using a custom biomechanical apparatus.

Evaluating the Readability of Online Patient Education Materials Regarding Shoulder Surgery: How Do Medical Institution Web Sites Rate?

This study evaluated the readability of online patient education materials on shoulder surgery. Medical and nonmedical institution web sites were compared and it was hypothesized that medical institution materials are written at lower grade levels than nonmedical institution materials, because medical institutions understand physician-patient interactions. Eighty-six articles were scored according to 10 readability tests: cumulative combined average grade level was 12.
