Operative Vs. Non-Operative Treatment Of Z-Type Clavicle Shaft Fractures In Adolescents: A Retrospective Study, Iulio Dobrin, Colin Van Wagoner, Ehab Saleh

Conference Presentation Abstracts

OBJECTIVE: Clavicle fractures are common in both adult and pediatric populations.1 Yet, the literature describes differences regarding treatment in such fractures between these populations, favoring operative treatment for adults and nonoperative treatment for pediatric patients.2 There is particular uncertainty for treating a subgroup of adolescent clavicle fractures known as the Z-type comminuted fracture which, being a completely displaced and complex fracture pattern, can prove to have different healing rates than other midshaft clavicle fractures. Because of concerns about healing and bony prominences, these types of fractures are commonly treated surgically, despite an increasing body of literature indicating equivalent outcomes in …

Canary In The Carpal Tunnel: A Pilot Study Of The Value Of The Screening For Amyloidosis In Carpal Tunnel Syndrome, Trevor Ruesch, Nevil Khurana, Logan Hansen Md, Katiya Barkho, Julia Malewicz, Charles Day Md

Medical Student Research Symposium

Introduction/Purpose:

Transthyretin amyloidosis occurs in two forms, hereditary transthyretin amyloidosis (hATTR), and wild-type ATTR (wtATTR)². Amyloidosis can result in restrictive cardiomyopathy presenting as heart failure with preserved ejection fraction (HFpEF)⁴. A growing body of evidence demonstrates that amyloidosis may be underdiagnosed and can be caught earlier in the disease course⁵. The proteins causing amyloidosis can also deposit into various tissues including the carpal tunnel leading to carpal tunnel syndrome ².

In this pilot study, we propose that early detection of amyloid via a biopsy of the transverse carpal ligament or tenosynovium in the …

Pulling The Trigger On Patient Care: A Comparison Of Asc And Hopd Settings For Trigger Finger Release, Carinne M. Jarvis, Nooraldin Kamalaldin, Hunter Cohn, Meet S. Patel, Charles S. Day

Medical Student Research Symposium

Introduction

There is an increased focus on balancing cost-effectiveness with positive patient outcomes. Trigger finger release (TFR) offers an opportunity to compare its value in a hospital outpatient department (HOPD) versus an ambulatory surgical center (ASC). We hypothesized that TFR performed in an ASC provides greater value.

Methods

Time-Driven Activity-Based Costing (TDABC) was used to collect cost data for each procedure. Steps in the patient care pathway were timed, and costs were categorized as:

• Direct Variable: Staff salaries, supplies

• Direct Fixed: Facility, utilities

• Indirect: Administration, marketing

Triangular Fibrocartilage Complex: An Anatomical And Medical Illustration Study., Hallie Tiburzi, Carlos A G Machado, Massimo S D'Antoni, R Shane Tubbs

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Recent advances in small-joint arthroscopy and cutting-edge magnetic resonance imaging systems have enabled orthopedic surgeons to perform more complex repairs of the wrist. Such repairs can include those of the triangular fibrocartilage complex (TFCC) of the wrist that necessitates a reappraisal of its morphometry with special emphasis on the relationship between its articular disc (AD) and surrounding tissues. The TFCC AD is a fibrocartilaginous, biconcave structure located between the ulnar styloid process and the carpal bones of the wrist. We carefully dissected and measured the ADs of 58 wrists from 34 embalmed cadavers (20 females, 14 males) and fabricated three-dimensional …

Nerve Transfers For Median Nerve Injury, Corinne Wee

Faculty Scholarship

Due to its role in hand function, median nerve injuries can have a significant impact on patients’ lives. Nerve transfers can be performed alone or in conjunction with tendon transfers to restore critical functions supplied by the median nerve, with a particular emphasis on restoring grasp, pinch, and sensation. Continued study into possible nerve transfers for median nerve injury has led to multiple options that can be tailored to the patient's demands, deficits, and injury pattern.

Two-Dimensional Preoperative Digital Templating Is Less Accurate When Using A Collared Triple Taper Stem Versus A Single Taper Design, Claudio Diaz-Ledezma, Angel X. Xiao, Juan David Lizcano, Erik N. Hansen, Camilo Restrepo, William J. Hozack

Rothman Institute Papers

Background

Collared triple taper stems (CTTS) and single taper stems (STS) have an excellent performance in primary total hip arthroplasty (THA). While 2-dimensional radiographic templating is accurate for STS, data are lacking for CTTS. We hypothesize that CTTS’ more anatomical design in the anteroposterior dimension may lead to inaccurate templating sizing. This study compared templating accuracy of CTTS to a predecessor STS in THA patients.

Methods

106 THA performed with CTTS were compared to 106 THA performed with STS by 2 high-volume surgeons. The stems chosen for comparison were manufactured by the same company, use the same templating software, shared …
