Short-term radiographic analysis of a stemless humeral component for anatomic total shoulder arthroplasty.

Background: Standard stemmed humeral implants have traditionally been utilized for total shoulder arthroplasty (TSA) with a recent trend to implant smaller stems including short and stemless humeral designs. However, the rate of stress shielding after stemless TSA has not been primarily studied. Therefore, the objective of this study is to report the short-term survivorship and radiographic analysis of a stemless humeral implant.

Outcomes of arthroscopic tuberoplasty for symptomatic irreparable rotator cuff tendon tear without pseudoparalysis.

Background: The purpose of this study is to report the outcomes in patients undergoing arthroscopic tuberoplasty for symptomatic irreparable rotator cuff tear (RCT).

Methods: This is a retrospective cohort study comparing preoperative and postoperative data of patients undergoing arthroscopic tuberoplasty for symptomatic irreparable RCT. Exclusion criteria included open tuberoplasty, concomitant partial RCT repair, glenohumeral arthritis, concomitant ipsilateral extremity fractures, <12 months follow-up, or pseudoparalysis.

Analysis of patient's willingness and concerns for discharge following shoulder arthroplasty.

Background: Patient's willingness and barriers for discharge after shoulder arthroplasty (SA) has not been studied. The aim of this study was to prospectively analyze patient's willingness for discharge and barriers to discharge beyond postoperative day #1 (POD#1) after SA.

Methods: In this prospective study, patients undergoing primary or revision SA (anatomic, reverse, or hemiarthroplasty) at our institution were enrolled to determine their willingness and concerns for discharge after SA.

Outcomes of reverse shoulder arthroplasty following failed superior capsular reconstruction.

Background: History of prior rotator cuff repair (RCR) may adversely affect the outcomes of reverse total shoulder arthroplasty (RTSA), but there is no information regarding the influence of prior superior capsular reconstruction (SCR) surgery on the outcomes of RTSA. The purpose of this study is to evaluate the outcomes of RTSA following failed arthroscopic SCR.

Methods: All patients who underwent RTSA for failed SCR (SCR cohort) at our institution were identified from our institutional database.

Marking Pen Bacterial Contamination During Shoulder Surgery.

Background: Equipment used to guide surgical incisions has been shown to be a source of bacterial contamination during surgery.

Purpose/hypothesis: To compare the culture-positive rates of sterile marking pens used before and after skin preparation for shoulder surgery. It was hypothesized that there will be no difference in culture-positive rates from marking pens used after skin preparation compared with before skin preparation.

Complex Region Pain Syndrome Following Shoulder Surgery.

Purpose: To describe the clinical features, treatment, and outcomes in patients with complex region pain syndrome (CRPS) following shoulder surgeries.

Methods: Three patients were diagnosed with CRPS according to the Budapest criteria. Patients were followed up prospectively at regular intervals for a minimum of 2 years.

Pectoralis Major Tendon Tear: A Critical Analysis Review.

»: Pectoralis major (PM) tendon tears are predominantly seen in young men, and the majority of tears occur as tendon avulsions involving the sternal head. Weightlifting, specifically bench-pressing, and sporting activities with eccentric overloading of the PM tendon are the 2 most common activities that result in PM injury.

»: Early surgical repair or reconstruction should be offered to younger, active patients with a complete PM tear; the majority of the patients undergoing surgical repair achieve good-to-excellent outcomes.

Locked Anterior-Inferior Sternoclavicular Joint Dislocation: A Case Report.

Case: We report a rare variant of sternoclavicular joint (SCJ) dislocation, namely locked anterior-inferior dislocation, with unique clinical, radiographic, and intraoperative findings. In this variant, the medial clavicle was displaced anteriorly and inferiorly and locked in the manubrial-intercostal space, with corresponding mechanical dysfunction of the ipsilateral shoulder girdle joints. Symptoms unique to this variant included painful neck spasms and limited glenohumeral elevation.

A model to evaluate Pauwels type III femoral neck fractures.

While many femoral neck fractures can be reliably treated with surgical intervention, Pauwels III femoral neck fractures in the young adult population continue to be a challenging injury, and there is no consensus on optimal treatment. As such, there are past and ongoing biomechanical studies to evaluate the fixation provided by different constructs for this inherently unstable fracture. While many investigations rely on cadavers to evaluate the biomechanical performance of a construct, significant inter-subject variability can confound the analysis.

The New Surgical Technique for Improving Total Knee and Hip Arthroplasty Outcomes: Patient Selection.

Background: Inclusion of patient satisfaction scores in setting reimbursements has been suggested by health care policy makers to contain cost and improve outcomes. The Short Form 36 Health Survey (SF-36) score provides a health-related quality of life (HRQoL) measure of arthroplasty outcome. Although previous work identified factors that influence this score for hip and knee arthroplasty patients, they did not focus on how a surgeon might use this information in a clinical setting.

Metal ions as inflammatory initiators of osteolysis.

Osteolysis and aseptic loosening currently contribute 75 % of implant failures. Furthermore, with over four million joint replacements projected to be performed in the United States annually, osteolysis and aseptic loosening may continue to pose a significant morbidity. This paper reviews the osteolysis cascade leading to osteoclast activation and bone resorption at the biochemical level.

Greater trochanteric hip pain.

In the patient with lateral hip pain, there is a broad differential diagnosis, making appropriate evaluation and management challenging. Greater trochanteric pain syndrome is a term used to denote chronic lateral hip pain and encompasses several painful soft tissue diagnoses including coxa saltans, trochanteric bursitis, and gluteus minimus and medius tendon tears. An overview of these common causes is presented through a series of cases that encompass the anatomic associations, classic presentations, diagnostic tests, and management strategies unique to each disorder.
