Clinical Significance of Lateral Pedicle Screw Malposition in Lumbar Spine Fusion.

Study Design: Retrospective cohort study.

Objective: Our objective was to determine whether lateral pedicle screw breach affects fusion rates and patient-reported outcomes in lumbar fusion surgery.

Summary Of Background Data: Although lateral pedicle screw malposition is considered relatively benign, few studies have focused specifically on clinical outcomes or fusion rates associated with lateral screw malposition.

Reassessing the minimum two-year follow-up standard after total shoulder arthroplasty-Is one year sufficient?

Background: US Food and Drug Administration Investigation Device Exemption studies and academic journals emphasize the importance of two-year follow-up data in reporting outcomes of total shoulder arthroplasty, but there is limited data evaluating appropriate follow-up length. We aim to evaluate change in postoperative outcomes and complications between one and two years following anatomic and reverse total shoulder arthroplasties.

Methods: We retrospectively identified 250 patients who underwent anatomic and reverse total shoulder arthroplasties between 2013 and 2016 from a single surgeon arthroplasty registry.

The Majority of Patients Aged 40 and Older Having Allograft Anterior Cruciate Ligament Reconstruction Achieve a Patient Acceptable Symptomatic State.

Purpose: To evaluate patient satisfaction, retear rates, and patient-reported outcomes (PROs) in patients aged 40 and older undergoing allograft anterior cruciate ligament reconstruction (ACLR). The secondary goal was to compare these parameters between groups of patients with intact versus failed grafts, and to evaluate these in relation to a historically reported International Knee Documentation Committee (IKDC) patient-acceptable symptoms state (PASS) score.

Methods: Records of patients aged 40 and older who underwent ACLR between 2005 and 2016 at a single institution with a minimum 2-year follow-up were retrospectively reviewed.

The Flexion Initiation Test and an Evidence-Based Diagnostic Algorithm for Distal Biceps Tendon Tears.

Purpose: The purpose of this study was (1) to assess the flexion initiation test's (FIT) ability to detect distal biceps tendon tears (DBTT) in a cohort of consecutive patients presenting with elbow pain and (2) to generate a reliable evidence-based diagnostic algorithm using a combination of both the FIT and hook tests.

Methods: We performed a retrospective review of 125 consecutive patients who presented with elbow pain, all of which had the FIT and hook test performed prior to imaging/further intervention. The integrity of the tendon was determined during surgery or by magnetic resonance imaging.

Drivers of Cost in Primary Single-Level Lumbar Fusion Surgery.

Study Design: Retrospective cohort.

Objectives: Allocating cost is challenging with traditional hospital accounting. Time-driven activity-based costing (TDABC) is an efficient method to accurately assign cost.

Reassessing glenoid inclination in reverse total shoulder arthroplasty with glenosphere lateralization.

Aims: Existing literature indicates that inferiorly inclined glenoid baseplates following reverse total shoulder arthroplasty (RSA) produce better outcomes compared to superiorly inclined baseplates. We aim to compare clinical outcomes for RSAs with superiorly and neutrally/inferiorly inclined lateralized glenospheres.

Methods: We retrospectively reviewed 154 consecutive patients undergoing RSA between July 2015 and July 2017 by one single-fellowship trained surgeon (AJ).

Association between a history of depression and anti-müllerian hormone among late-reproductive aged women: the Harvard study of moods and cycles.

Background: There is conflicting evidence regarding the association between a history of depression and risk of early menopause. In a cohort of premenopausal women, we investigated the association between depression history and ovarian reserve, as measured by anti-müllerian hormone (AMH).

Methods: The Harvard Study of Moods and Cycles (HSMC) was a prospective cohort study of women living in the Boston, MA metropolitan-area (1995-1999).

The Effect of a Skin Barrier Film on the Incidence of Dressing-Related Skin Blisters After Spine Surgery.

Tension blisters from adhesive dressings may lead to pain and delayed surgical wound healing for surgical patients and cause an institutional cost burden. Commercial skin barrier film products may reduce dressing-related postoperative skin blistering in surgical patients. Project investigators at an orthopedic specialty hospital randomized 185 surgical spine patients to receive either a standard wound dressing (ie, control group) or a dressing with the addition of a skin barrier film applied beneath it (eg, treatment group).

Anatomic and Patient Risk Factors for Postoperative Periprosthetic Hip Fractures: A Case-Control Study.

Background: Periprosthetic fracture remains a major source of reoperation following total hip arthroplasty (THA). Within 90 days of surgery, fractures may occur spontaneously or with minor injury and are therefore more likely related to patient factors including anatomic variation.

Methods: From 2008 to 2018, 16,254 primary THAs were performed at our institution; of those, 48 were revised for periprosthetic fracture within 90 days of surgery.
