What Are the Effects of Remplissage on 6-Month Strength and Range of Motion After Arthroscopic Bankart Repair? A Multicenter Cohort Study.

Background: Patients who have undergone shoulder instability surgery are often allowed to return to sports, work, and high-level activity based largely on a time-based criterion of 6 months postoperatively. However, some believe that advancing activity after surgery should be dependent on the return of strength and range of motion (ROM).

Hypothesis: There will be a significant loss of strength or ROM at 6 months after arthroscopic Bankart repair with remplissage compared with Bankart repair alone.

Targeted Muscle Reinnervation at the Time of Major Limb Amputation in Traumatic Amputees: Early Experience of an Effective Treatment Strategy to Improve Pain.

Background: Orthopaedic trauma etiologies are a common cause for amputation. Targeted muscle reinnervation (TMR) is a technique aimed at reducing or preventing pain and improving function. The purpose of this study was to examine postoperative phantom limb pain and residual limb pain following TMR in orthopaedic trauma amputees.

Periprosthetic Infection After Reverse Shoulder Arthroplasty: a Review.

Purpose Of Review: Periprosthetic infection is a relatively rare but potentially devastating complication after shoulder arthroplasty. The purpose of this article is to review the incidence, diagnosis, prevention, and management of periprosthetic infections after reverse shoulder arthroplasty, with a focus on literature published within the last 5 years.

Recent Findings: The 2018 International Consensus Meeting on Musculoskeletal Infection provides us with a framework for the diagnosis and management of periprosthetic infections after shoulder arthroplasty.

Biceps Tenodesis for Superior Labrum Anterior-Posterior Tear in the Overhead Athlete: A Systematic Review.

Background: Superior labrum anterior-posterior (SLAP) lesion is a common shoulder injury, particularly in overhead athletes. While surgical management has traditionally consisted of SLAP repair, high rates of revision and complications have led to alternative techniques, such as biceps tenodesis (BT). While BT is commonly reserved for older nonoverhead athletes, indications for its use have expanded in recent years.

Discharge to inpatient care facilities following hip fracture surgery: incidence, risk factors, and 30-day post-discharge outcomes.

Background: Discharge to an inpatient care facility (skilled-care or rehabilitation) has been shown to be associated with adverse outcomes following elective total joint arthroplasties. Current evidence with regard to hip fracture surgeries remains limited.

Methods: The 2015-2016 ACS-NSQIP database was used to query for patients undergoing total hip arthroplasty, hemiarthroplasty and open reduction internal fixation for hip fractures.

Superior Labral Anterior Posterior Repair and Biceps Tenodesis Surgery: Trends of the American Board of Orthopaedic Surgery Database.

Background: Recent evidence has specified indications for performing superior labral anterior posterior (SLAP) repair and biceps tenodesis (BT) for the treatment of bicipital-labral lesions in the shoulder. Trends in performance of these procedures are expected to reflect the growing body of research regarding this topic.

Purpose: To report practice trends for the surgical treatment of SLAP lesions utilizing the American Board of Orthopaedic Surgery (ABOS) database, particularly in older patients.

High prevalence of outpatient falls following elective shoulder arthroplasty.

Background: This study characterized the prevalence and risk factors of inpatient and outpatient postoperative falls in patients undergoing elective shoulder arthroplasty.

Methods: A retrospective chart review of 198 patients undergoing anatomic or reverse total shoulder arthroplasty or hemiarthroplasties at one institution between 2015 and 2017 was reviewed to determine the prevalence of inpatient and outpatient falls up to 90 days after discharge. Univariate and multivariate analyses were conducted to assess potential risk factors for postoperative falls including demographics, indication for surgery, surgical procedure, medical history, length of hospital stay, perioperative hemoglobin, need for transfusion, and discharge disposition.

Are Patients Who Undergo the Latarjet Procedure Ready to Return to Play at 6 Months? A Multicenter Orthopaedic Outcomes Network (MOON) Shoulder Group Cohort Study.

Background: The Latarjet procedure is growing in popularity for treating athletes with recurrent anterior shoulder instability, largely because of the high recurrence rate of arthroscopic stabilization, particularly among contact athletes with bone loss.

Purpose: (1) To evaluate return of strength and range of motion (ROM) 6 months after the Latarjet procedure and (2) to determine risk factors for failure to achieve return-to-play (RTP) criteria at 6 months.

Study Design: Case-control study; Level of evidence, 3.

Patient-Reported Outcomes of Achilles Tendon Repair Using the Modified Gift-Box Technique With Nonabsorbable Suture Loop: A Consecutive Case Series.

Early Postoperative Improvement in Sleep and Pain After Carpal Tunnel Release.

Carpal tunnel syndrome (CTS) is the most common compressive neuropathy of the upper extremity. We sought to assess the subjective improvement in preoperative symptoms related to CTS, particularly those affecting sleep, and describe opioid consumption postoperatively. All patients undergoing primary carpal tunnel release (CTR) for electromyographically proven CTS were studied prospectively.

Tissue damage volume predicts organ dysfunction and inflammation after injury.

Background: Multiply injured patients (MIPs) are at risk to develop multiple-organ failure (MOF) and prolonged systemic inflammation response syndrome (SIRS). It is difficult to predict which MIPs are at the highest risk to develop these complications. We have developed a novel method that quantifies the distribution and physical magnitude of all injuries identified on admission computed tomography scanning called the Tissue Damage Volume (TDV) score.

SHOCK VOLUME: A PATIENT-SPECIFIC INDEX THAT PREDICTS TRANSFUSION REQUIREMENTS AND ORGAN DYSFUNCTION IN MULTIPLY INJURED PATIENTS.

Multiply injured patients (MIPs) in hemorrhagic shock develop oxygen debt which causes organ dysfunction and can lead to death. We developed a noninvasive patient-specific index, Shock Volume (SV), to quantify the magnitude of hypoperfusion. SV integrates the magnitude and duration that incremental shock index values are elevated above known thresholds of hypoperfusion using serial individual vital sign data.

The effect of pH versus base deficit on organ failure in trauma patients.

Background: Base deficit (BD) calculations are affected by trauma-related changes in circulating concentrations of anions after injury. In contrast, pH is a direct measurement that corresponds to hypoperfusion. We hypothesized that changes in pH would more closely correspond to organ dysfunction compared with changes in BD.

Effects of dynamic warm-up on lower body explosiveness among collegiate baseball players.
