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 …

Medical Student Research Symposium

Background

The anterior cruciate ligament (ACL) is often debrided during reconstruction (ACLR) to improve visualization. However, remnant ACL tissue contains nerve fibers and including remnant tissue in ACLR could provide benefit. Therefore, a technique was developed that preserves the tibial remnant and incorporates it into ACLR: Hybrid Remnant Preservation Reconstruction (HRPR) ACLR. This study compares HRPR-ACLR to traditional reconstruction by comparing patient reported outcomes and complications.

Methods

Patients presenting to one surgeon's clinic with an ACL injury are screened. Exclusion criteria are patient age<14 years, multi-ligament injury, chronic tears, and revision ACLR. Patients are consented and randomized to HRPR or traditional ACLR. Demographics, patient-reported outcomes, range of motion (ROM) and complications were collected.

Results

Thirty-three patients were included, 20 HRPR and 13 controls. No demographic differences were noted. PROMIS-PF, …
