A Mild Case Of Pseudoachondroplasia In A Child: Lessons For Long-Term Primary Care, Alec J. Pupo D.O., Connor J. Stinson D.O., Autumn Dye D.O.

The Journal of Integrated Primary Care

Background: Pseudoachondroplasia (PSACH) is a rare autosomal dominant skeletal dysplasia caused by pathogenic variants in the cartilage oligomeric matrix protein (COMP) gene. It is classically characterized by early-onset growth failure, disproportionate short stature, progressive epiphyseal dysplasia, and premature degenerative joint disease. Although phenotypic variability has been reported, PSACH is often regarded as a uniformly severe condition with predictable orthopedic morbidity.

Case Presentation: We report an eleven-year-old female with genetically confirmed PSACH who demonstrates an unexpectedly mild clinical phenotype, despite a maternal history of severe disease requiring bilateral total hip replacement during adolescence. The patient exhibited mild hip dysplasia, evolving genu …

Conservative Management Of A Rare Clinical Phenomenon: Paraspinal Compartment Syndrome - A Review Of Existing Literature., Mark Lagreca, Arash Badragheh, Nathan Jones, Thomas Falconiero, Brian Danshaw

Orthopedic Surgery Resident Research

INTRODUCTION: This review of case series and case reports explores conservative management strategies for paraspinal compartment syndrome (PCS), a rare clinical condition. Extremity compartment syndrome has been shown to be managed most effectively with emergent surgical release of the fascial compartment. Given the rarity of PCS and the paucity of research in the literature, some authors have suggested the possibility of conservative treatment. There has been no study to date that has specifically investigated the cases of non-operative management of PCS.

MATERIALS AND METHODS: There are 16 case reports in the literature with 22 cases of PCS treated conservatively. The …

Clostridium Septicum: Cause Of Gas Gangrene In The Upper Extremity Leading To Proximal Trans-Humeral Amputation, A Review Of Clostridium Septicum., Mark Lagreca, Denise Chen, Patrick Frick, Genoveffa Morway, Austin Egger, Julia Mayberry

Orthopedic Surgery Resident Research

INTRODUCTION: Gas gangrene is a rare, often lethal infection of soft tissue that is commonly associated with the Clostridial species due to penetrating injuries. Case reports of spontaneous atraumatic gas gangrene due to the Clostridium septicum species are exceedingly rare. Atraumatic C. septicum is notably related to bowel pathologies, immunodeficiencies, and individuals with vascular insufficiency. The rapid progression of Clostridium myonecrosis contributes to its high mortality rates.

CASE REPORT: The authors report a case of a 71-year-old right-hand-dominant female who developed fulminant atraumatic left forearm pain and swelling. The patient was indicated for emergent irrigation and debridement (I&D) of the …

A Bone Of Contention: A Dynamic Ultrasound Assessment Of The Role Of The Radial Head In The Arthrokinematics Of The Proximal Radioulnar Joint, Kolson Lamb, Madison D. Hendricks, Courtney E. Grimes, Cameron A. Johnson, David Nguyen, Ruth Maher

Research Day

INTRODUCTION: The arthrokinematics of the proximal radioulnar joint (PRUJ) are believed to follow the convex-concave rule, meaning that when the convex radial head articulates with the concave radial notch on the ulna, rolling and gliding occur in opposite directions during forearm pronation and supination. Previous research using helical computerized tomography (CT) identified that the sequence of joint actions is in contrast with this rule, which would indicate a posterior glide of the radius on the ulna during pronation movement and the converse during supination.

OBJECTIVES: The aims of this study are to determine the arthrokinematics of the PRUJ while being …

Arthroscopic Suprapectoral Biceps Tenodesis: The Best Of Both Worlds, Tyler Pratte, Tyler Smith, Alfonso Arevalo, Joseph Wazen, David Rubenstein

Orthopedic Surgery Resident Research

Biceps tendinopathy and superior labrum anterior posterior lesions are a common source of shoulder pain and disability and can be effectively treated with biceps tenodesis. There are a variety of open and arthroscopic tenodesis techniques, but no one technique has demonstrated superiority. Arthroscopic techniques often disregard the extra-articular portions of the biceps tendon as a potential source of pain. Open techniques address this concern; however, they can be associated with wound complications, increased blood loss, nerve injury, and disruptions to surgical workflow. Here, we describe an all arthroscopic tenodesis technique at the suprapectoral zone of the tendon. This method addresses …

Laboratory-Reported Normal Value Ranges Should Not Be Used To Diagnose Periprosthetic Joint Infection., Salvador A. Forte, Joseph A. D'Alonzo, Zachary Wells, Brett Levine, Stephen Sizer, Carl Deirmengian

Orthopedic Surgery Resident Research

INTRODUCTION: Clinical laboratories offer several multipurpose tests, such as the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), which are not intended to diagnose any specific disease but are used by clinicians in multiple fields. The results and laboratory interpretation (normal/abnormal) of these multipurpose tests are based on laboratory-reported normal thresholds, which vary across clinical laboratories. In 2018, the International Consensus Meeting on Musculoskeletal Infection (2018 ICM) provided a gold-standard definition to diagnose periprosthetic joint infection (PJI) which included many multipurpose laboratory tests, along with thresholds optimized to diagnose PJI. The discrepancy between laboratory-reported normal thresholds and 2018 ICM-recommended PJI-optimized …
