Risk Factors For The Development Of A Symptomatic Contralateral Discoid Lateral Meniscus, Jason Nielson, Sean Davis, Aaron Gray, Brock Wentz 2021 School of Medicine, University of Nevada

Risk Factors For The Development Of A Symptomatic Contralateral Discoid Lateral Meniscus, Jason Nielson, Sean Davis, Aaron Gray, Brock Wentz

Western Journal of Orthopaedics

Background: Discoid menisci (DM) are oval or disc shaped menisci, differing from the normal crescent shaped meniscus. This difference in shape may be one factor as to why DM are more prone to injury when compared to normal menisci. The purpose of this study was to evaluate potential risk factors that may lead to the development of symptoms, requiring arthroscopic saucerization in adolescents with a history of symptomatic DM in the contralateral extremity. Methods: We retrospectively reviewed 126 patients with an arthroscopic diagnosis of DM to evaluate for the presence of a symptomatic contralateral DM variant. Mildly symptomatic DM status ...


Considerations In Surgical Timing For Femoral Shaft Fractures, Trevor Crean, William Curtis, Thomas A. DeCoster 2021 The University of New Mexico Health Sciences Center

Considerations In Surgical Timing For Femoral Shaft Fractures, Trevor Crean, William Curtis, Thomas A. Decoster

Western Journal of Orthopaedics

Femoral shaft fractures are a common orthopaedic injury. They are generally treated with intramedullary nailing. The optimal timing of operative treatment is variable and debated. Relatively simple femoral shaft fractures can be successfully treated in less than 24 hours in most health care systems. Femoral shaft fractures can be more complicated owing to various factors, such as multiple traumatic injuries, associated conditions, etc. These more complicated femoral shaft fractures benefit from stabilization within the first 6 hours to minimize complications. Stabilization of the long bones helps achieve an upright chest position and improves pulmonary, circulatory, and musculoskeletal function. Some patients ...

Effect Of Patient-Surgeon Orientation On Plunge Depth During Plate Fixation Of Clavicle Fractures, Aaron Mullane, Layla A. Haidar, Adam Kozemchak, Colton Wayne

Western Journal of Orthopaedics

Background: Operative management of clavicle fractures indicated for open reduction internal fixation poses significant risk to critical anatomic structures. The associated risks to the underlying neurovascular structures during clavicle fixation as a result of plunge depth for patients in the supine position in comparison to patients in the beach-chair position is currently unknown. The purpose of this study was to compare plunge depth measurements between the supine and beach-chair positions during plate fixation of clavicle fractures. Methods: The participant population at this single institution was comprised of residents, fellows, and fellowship-trained, attending orthopaedic surgeons. The participants drilled three bicortical holes ...

A Novel High Tibial Biplanar Osteotomy Technique For Simultaneous Coronal And Sagittal Correction: A Case Example, Ryan C. Price, Kathryn C. Helmig, Dustin L. Richter, Robert C. Schenck Jr

Western Journal of Orthopaedics

Medial opening wedge high tibial osteotomy (HTO) can provide symptom relief, improved ligamentous stability, and lower failure rates in patients with symptomatic medial knee osteoarthritis, ligament instability, and varus alignment after ligament reconstruction. It has been reported that correcting coronal plane abnormalities with a medial opening wedge HTO has resulted in altered posterior tibial slope angle (PTSA). We describe a 38-year-old woman with a history of severe polytrauma who presented with an anterior cruciate ligament tear in the setting of increased PTSA and a posterolateral corner injury with varus deformity of the knee. A medial biplanar HTO was performed using ...


Cartilage Restoration Of The Patella Using Prochondrix® Osteochondral Allograft: A Case Report, Evan D. Boyd, Michael S. Barnum, James R. Slauterbeck 2021 University of Vermont

Cartilage Restoration Of The Patella Using Prochondrix® Osteochondral Allograft: A Case Report, Evan D. Boyd, Michael S. Barnum, James R. Slauterbeck

Western Journal of Orthopaedics

Articular cartilage injuries are challenging to treat because of the limited healing potential of articular cartilage. Various cartilage restoration procedures have been developed to restore the protective role of articular cartilage and to delay or prevent additional damage to the articular surface. ProChondrix® Cartilage Restoration Matrix is a cryopreserved hyaline cartilage allograft with viable chondrocytes and growth factors necessary to promote its incorporation and viability. We describe a 19-year-old man with a well-contained, full-thickness cartilage defect on his patella. He subsequently underwent cartilage restoration with a ProChondrix® osteochondral allograft. At 1-year postoperatively, the patient had both clinical and radiographic evidence ...


Reconstruction Of A Chronic Quadriceps Tendon Rupture After Multiple Failed Repair Attempts: Technique And Case Report, Lauren Edge, Elizabeth McLeod, Om Pathak, Justin Bartley 2021 Burrell College of Osteopathic Medicine

Reconstruction Of A Chronic Quadriceps Tendon Rupture After Multiple Failed Repair Attempts: Technique And Case Report, Lauren Edge, Elizabeth Mcleod, Om Pathak, Justin Bartley

Western Journal of Orthopaedics

Rupture of the quadriceps tendon is a relatively uncommon injury that requires prompt surgical intervention to restore the function of the extension apparatus of the knee. Early, definitive surgical intervention generally produces excellent results. In the case of delayed surgery or re-rupture, the tendon is often retracted and scarred, thus complicating subsequent repairs and resulting in poor outcomes. We describe a middle-aged man who presented 4 years after his initial quadriceps rupture, following two repair attempts that failed. Upon presentation, he was unable to perform any active extension at the knee, and he ambulated with the use of a hinged ...

Bilateral Peroneal Tendon Subluxation Associated With Complex Hindfoot Fractures: A Case Report, Benjamin C. Howse, Benjamin D. Packard, Rick J. Gehlert

Western Journal of Orthopaedics

A 41-year-old man presented to the emergency department after crashing his dirt bike and sustaining bilateral subtalar fracture dislocations. The left talus underwent open reduction internal fixation. At his first postoperative visit, the patient was found to have bilateral peroneal tendon subluxation (PTS). This case report discusses the cause of PTS and the challenges associated with accurate identification and diagnosis of this injury. We review the diagnostic and therapeutic challenges associated with injury, the negative impact on clinical outcomes, and the association between PTS and hindfoot trauma.

Distal Radial Shaft Malunion And Distal Radioulnar Joint Instability 8 Years After Postoperative Plate Failure: A Case Report, Allicia O. Imada, Casey D. McDonald, Deana Mercer 2021 The University of New Mexico Health Sciences Center

Distal Radial Shaft Malunion And Distal Radioulnar Joint Instability 8 Years After Postoperative Plate Failure: A Case Report, Allicia O. Imada, Casey D. Mcdonald, Deana Mercer

Western Journal of Orthopaedics

Radius shaft fractures often require operative treatment after skeletal maturity to restore functional range of motion. If the radial bow is not anatomically restored, pain and instability can occur from bony impingement and disruption of the distal radioulnar joint (DRUJ). We describe a 25-year-old woman with a radius shaft malunion and DRUJ instability. Eight years prior, at the age of 17, she underwent open reduction and internal fixation for a radial shaft fracture with subsequent reinjury at 10 weeks postoperatively. The reinjury was treated nonoperatively, and the patient went on to have painful range of motion and DRUJ instability. Radiographs ...


The Chevron Capitate-Trapezoid Joint: A Case Report, Dean W. Smith 2021 University of Texas Health Sciences Center

The Chevron Capitate-Trapezoid Joint: A Case Report, Dean W. Smith

Western Journal of Orthopaedics

Anatomical variations to the human skeletal system are common and frequently reported in the literature. The structures around the hand and wrist are no exception, and these variations can affect ligaments, tendons, muscles, nerves, arteries, joints, and bone morphology. Musculoskeletal health care providers must be familiar with normal, individual variations when encountered during patient care and diagnostic imaging. In some instances, morphological variations have resulted in differences in kinematics, while others have been found in association with certain medical conditions. We discuss an unusual variation of the capitate-trapezoid joint. To the best of our knowledge, no prior studies have previously ...

A Systematic Review To Examine Functional Recovery After Total Knee Arthroplasty And Successful Physical Therapy Protocols, Dominique M. Patterson, Colin F.K. Hansen, Yuri Yoshida

Western Journal of Orthopaedics

Background: Total knee arthroplasty (TKA) continues to be the most common elective procedure performed every year, with the goal to reduce pain and improve return to functional activities. Recent studies have investigated new surgical techniques and therapeutic interventions to determine which protocols result in reduced pain and accelerate return to function. Methods: We systematically reviewed 131 out of 301 studies between 1996 and 2019 to assess trends in patient functional performance and perceptive functional recovery after TKA from preoperative up to 2 years postoperative. We evaluated functional outcome measures recommended by the Osteoarthritis Research Society International. Results that considerably deviated ...

Background: Gunshot injuries frequently involve the foot and ankle. The standard of care for treatment of gunshot injuries to the foot and ankle is not clear. To better understand these injuries, we completed a retrospective review of foot and ankle gunshot injuries at a level-1 trauma center seen as orthopaedic consults over a 2-year period. Methods: Orthopaedic consults for foot and ankle gunshot injuries from June 1st, 2018, through May 31st, 2020, were reviewed. Patient characteristics, zone of injury, mechanism of injury, associated injuries, treatment, follow-up, and outcomes were recorded. Results: Forty-eight foot and ankle gunshot injuries were identified, encompassing ...


A Novel Method In The Classification Of Proximal Fifth Metatarsal Fractures, Kathryn Yeager, Benjamin Packard, Richard A. Miller, Shravin Sridhar 2021 The University of New Mexico Health Sciences Center

A Novel Method In The Classification Of Proximal Fifth Metatarsal Fractures, Kathryn Yeager, Benjamin Packard, Richard A. Miller, Shravin Sridhar

Western Journal of Orthopaedics

Background: Proximal fifth metatarsal fractures are common. The authors previously performed a study examining the inter- and intraobserver reliability of the Lawrence and Botte Classification, which showed poor interobserver reliability of 16.67%. A novel approach was proposed for the classification of fifth metatarsal fractures using a mortise ankle radiographic view. Methods: The observers from the authors’ prior study reviewed non-weight bearing mortise views of 20 patients with isolated fifth metatarsal base fractures. These radiographs were identified from the 60 radiographs from the authors’ prior study. Five physicians evaluated the radiographs and classified the fractures as type 1, 2, or ...


Hamstring Strength Recovery In Relation To Landing Patterns Following Anterior Cruciate Ligament Reconstruction: A Case Comparison Report, Kelsey A. Edwards, Rebecca A. Dutton, Yuri Yoshida, Dustin L. Richter 2021 The University of New Mexico Health Sciences Center

Hamstring Strength Recovery In Relation To Landing Patterns Following Anterior Cruciate Ligament Reconstruction: A Case Comparison Report, Kelsey A. Edwards, Rebecca A. Dutton, Yuri Yoshida, Dustin L. Richter

Western Journal of Orthopaedics

Introduction: Deficits in quadriceps strength following anterior cruciate ligament reconstruction (ACLR) are common and can be associated with biomechanical asymmetries during landing tasks. The relationship between quadriceps strength and knee function during ACLR recovery is well established. However, less is known regarding the role of hamstring strength in functional recovery after ACLR. We examined movement patterns during a drop-landing task in three patients following ACLR with different levels of quadriceps and hamstring strength. Methods: Three participants were assessed for quadriceps and hamstrings strength, functional performance, and lower-extremity biomechanics captured by a 3D motion analysis 6 months after ACLR. Results: Participant ...


Bisphosphonate Associated Atypical Femur Fracture And Contralateral Impending Atypical Femur Fracture In A Pediatric Patient With Osteogenesis Imperfecta: A Case Report, Benjamin Albertson, Taylor Polander, Selina Silva 2021 The University of New Mexico Health Sciences Center

Bisphosphonate Associated Atypical Femur Fracture And Contralateral Impending Atypical Femur Fracture In A Pediatric Patient With Osteogenesis Imperfecta: A Case Report, Benjamin Albertson, Taylor Polander, Selina Silva

Western Journal of Orthopaedics

Atypical femur fractures are rare, low-energy fractures that involve a specific constellation of radiographic findings. These fractures have been well described in adult osteoporotic patients on long-term bisphosphonates; however, little to no literature exists on atypical femur fractures in pediatric patients on long-term bisphosphonates. The use of bisphosphonates as treatment of osteogenesis imperfecta is common to reduce fracture rate and improve bone mineral density. We describe a 15-year-old adolescent boy with type I osteogenesis imperfecta on long-term bisphosphonate therapy. He presented with an atypical right femur fracture and an impending left femur fracture. To the authors’ knowledge, these findings represent ...


New Diagnosis Of X-Linked Agammaglobulinemia Presenting As Multi-Focal Acute Pseudomonal Osteomyelitis And Septic Arthritis In A 16-Month Old Boy: A Case Report, Walter Dehority 2021 The University of New Mexico Health Sciences Center

New Diagnosis Of X-Linked Agammaglobulinemia Presenting As Multi-Focal Acute Pseudomonal Osteomyelitis And Septic Arthritis In A 16-Month Old Boy: A Case Report, Walter Dehority

Western Journal of Orthopaedics

A previously healthy 16-month-old boy presented with 5 days of fever, a limp favoring his right side, and swelling and erythema of the dorsal left foot and left great toe. Contrasted magnetic resonance imaging revealed septic arthritis of the left knee, the interphalangeal joint of the left great toe, and the left subtalar and ankle joints. He had osteomyelitis of the left talus and intraosseous abscess formation in the left calcaneus. Cultures of the blood, left knee synovial fluid, and abscess fluid all showed growth of Pseudomonas aeruginosa. He was subsequently diagnosed with X-linked agammaglobulinemia with a novel mutation in ...


Chronic Complex Volar Dislocation Of The Middle And Ring Finger Metacarpophalangeal Joint: A Case Report, Fernando Moreno, Jordan T. Carter, John J. Pisquiy, Michael M. Polmear 2021 Texas Tech Health Sciences Center

Chronic Complex Volar Dislocation Of The Middle And Ring Finger Metacarpophalangeal Joint: A Case Report, Fernando Moreno, Jordan T. Carter, John J. Pisquiy, Michael M. Polmear

Western Journal of Orthopaedics

Metacarpophalangeal (MCP) joint dislocations are uncommon injuries. Most dislocations occur dorsally, with volar dislocations being rarer owing to the architecture of the joint. Because of the rarity of the condition, there is no accepted standard treatment for these injuries. The most commonly affected digit is the ring finger, followed by the middle finger and then the small finger. Management depends on the complexity of the injury, with complex dislocations requiring open reduction owing to interposed soft tissue and repair of damaged ligaments and tendons. We describe a 52-year-old man with chronic MCP dislocation who underwent unsuccessful open reduction and subsequently ...
