21st Century Perspective On The Changing Pattern Of Nerve Injuries From Gunshot Wounds In The U.S., Thomas A. Decoster Jan 2026

21st Century Perspective On The Changing Pattern Of Nerve Injuries From Gunshot Wounds In The U.S., Thomas A. Decoster

Western Journal of Orthopaedics

Gunshot wounds (GSWs) with nerve injuries in the 21st century differ significantly from those reported in the 20th century. The vast majority are now low-velocity civilian injuries, in contrast to high-velocity military injuries previously reported. The rate of nerve injury in civilian GSWs is approximately 5%, compared with the 30% reported in military cohorts. However, the most common pattern of nerve injury in the current civilian population is neurotmesis and partial neurotmesis, in contrast to the majority axonotmesis of the military cohorts. In the 20th century, treatment generally consisted of watchful waiting for signs of spontaneous recovery over three months …

Peripheral Nerve Repair And Reconstruction: Current Techniques, Adjuncts, And Emerging Therapies, Niklaus Skipp, Lana Dokic, Christina Wassef, Jazzlyn Gonzalez, Ana Love, Heather Mercer, Deana Mercer

Western Journal of Orthopaedics

Peripheral nerve injuries require reconstruction when direct, tension-free repair is not possible. A range of reconstructive strategies are used to restore continuity and promote axonal regeneration, including graft-based reconstruction, nerve transfers, conduit-based repair, supercharged end-to-side augmentation, and emerging regenerative therapies. Autologous interfascicular nerve grafts and vascularized grafts remain established techniques, whereas processed nerve allografts provide a donor-sparing alternative. Nerve transfers are increasingly used for proximal injuries with long regeneration distances, and conduits are an option for gaps shorter than 5 mm. Nerve-wrapping techniques are used to reduce perineural scarring and preserve gliding in complex or revision cases. Emerging adjunctive therapies, …

Exploring The Interaction Between Cranial Nerves V And Vii In Chronic Eyelid Myokymia: A Case Report, Karina Miramontes, Adam Walsh, Tomas Tafoya

Western Journal of Orthopaedics

Eyelid myokymia involves involuntary contractions of the orbicularis oculi muscle and is commonly associated with stress, fatigue, and craniocervical factors. Emerging evidence suggests that altered trigeminocervical interactions and craniomandibular muscle tension may contribute to symptom persistence; however, the condition remains underrecognized in physical therapy. This report describes a 65-year-old woman with chronic benign eyelid myokymia and cervical pain who completed 12 physical therapy sessions that included suboccipital functional dry needling, temporomandibular soft-tissue mobilization (STM), and cervical stabilization exercises. A reduction in eyelid myokymia was first observed at the fifth visit, coinciding with the initiation of temporomandibular STM. These findings suggest …

Arthroscopic Management Of A Loose Body In The Pisotriquetral Joint: A Case Report, Giovanni Chioda, Tomas Holy, Nicholas Newcomb, Nathan Morrell Jan 2026

Arthroscopic Management Of A Loose Body In The Pisotriquetral Joint: A Case Report, Giovanni Chioda, Tomas Holy, Nicholas Newcomb, Nathan Morrell

Western Journal of Orthopaedics

The pisotriquetral joint is the smallest of the four joints comprising the wrist and is a source of ulnar-sided wrist pain. This condyloid joint connects the pisiform to the triquetrum and is supported by several surrounding ligaments. A variety of pathologies may affect the pisotriquetral joint, including the presence of loose bodies. Because of its small size and the inherent difficulty of visualization, the pisotriquetral joint is often overlooked as an independent joint. Techniques for arthroscopic visualization and loose-body removal have previously been described using the 6R and 4-5 portals. In the following case report, the authors describe successful visualization …

Liposome-Encapsulated Clodronate And Cox-2 Inhibitor Treatment Impair Ventilatory Recovery But Improve Compensatory Locomotor Function Following Cervical Spinal Cord Injury In Rats, Aaron L. Silverstein, Chris M. Calulot, Christopher J. Mclouth, John C. Gensel, Warren J. Alilain

Spinal Cord and Brain Injury Research Center Faculty Publications

Over half of all spinal cord injuries (SCIs) in the United States occur at the cervical level and can cause locomotor deficits and life-threatening breathing dysfunction. Interestingly, the bisphosphonate drug clodronate has shown efficacy in ameliorating tissue damage and improving locomotor recovery acutely after experimentally induced thoracic SCI. Thus, we hypothesized that clodronate treatment would improve recovery of breathing and locomotor function following a C2 hemisection (C2Hx) model of cervical SCI in rats. Serendipitously, changes to animal use guidelines led to the inclusion of carprofen, a non-steroidal anti-inflammatory drug (NSAID), as another independent variable in our study. We treated adult …

Traumatic Brain Injury Exacerbates Mitochondrial Dysfunction In App/Ps1 Knock-In Mice Through Time-Dependent Pathways, Elika Z. Moallem, Hemendra J. Vekaria, Teresa Macheda, Margaret R. Hawkins, Kelly N. Roberts, Samir P. Patel, Patrick G. Sullivan, Adam D. Bachstetter

Spinal Cord and Brain Injury Research Center Faculty Publications

Cerebral hypometabolism occurs in both traumatic brain injury (TBI) and Alzheimer's disease (AD), but whether these conditions act through distinct or overlapping mechanisms is unclear. TBI disrupts cerebral metabolism via blood–brain barrier damage, altered glucose transporter expression, calcium buffering abnormalities, and oxidative damage to metabolic enzymes. AD-related hypometabolism is linked to amyloid-β (Aβ) effects on mitochondria, including impaired respiration, oxidative stress, and altered mitophagy, fusion, and fission. We tested whether TBI-induced mitochondrial dysfunction exacerbates Aβ-mediated impairment using a closed-head injury (CHI) model in APP/PS1 knock-in (KI) mice. Injuries were delivered at 4–5 months of age, before plaque formation and mitochondrial …

Candidate Interaction Partners Of Calpain-5 Suggest Clues To Its Involvement In Neovascular Inflammatory Vitreoretinopathy, Jozsef Gal, Vimala Bondada, Rachel Crasta, Dorothy E. Croall, Calvin P. Vary, James W. Geddes Jan 2026

Candidate Interaction Partners Of Calpain-5 Suggest Clues To Its Involvement In Neovascular Inflammatory Vitreoretinopathy, Jozsef Gal, Vimala Bondada, Rachel Crasta, Dorothy E. Croall, Calvin P. Vary, James W. Geddes

Spinal Cord and Brain Injury Research Center Faculty Publications

Although calpain-5/CAPN5 is widely expressed in mammals, little is known regarding its functions. Pathogenic mutations of CAPN5 are causal for a devastating autoimmune eye disease, neovascular inflammatory vitreoretinopathy (NIV). To provide insight into both the physiological and pathological roles of CAPN5, it is essential to identify candidate interaction partners and possible substrates. Human SH-SY5Y neuroblastoma cells, transfected with full-length catalytically dead (Cys81Ala) CAPN5-3×FLAG, were used for anti-FLAG co-immunoprecipitation (co-IP) and quantitative proteomics using Sequential Window Acquisition of all THeoretical mass spectra (SWATH-MS). Fifty-one proteins were enriched at least four-fold, p < 0.01, relative to cells transfected with an empty FLAG vector. A high proportion (24/51) of candidate CAPN5 interaction partners are associated with protein quality control, including components of the chaperonin, chaperone, and ubiquitin–proteasome systems. Additional candidate interactors include tubulins, kinases, phosphatases, G proteins, and mitochondrial proteins. CAPN5 interactions for 14 of the candidate proteins were confirmed by co-IP and immunoblotting. Of these 14 proteins, 11 exhibited in vitro calcium-induced proteolysis following co-IP with WT CAPN5-3×FLAG. Impaired calcium-induced proteolysis of co-IP proteins was observed for the pathogenic CAPN5 variants R243L and R289W. Further studies are needed to validate the association of candidate CAPN5 interactors with proteins and complexes suggested by the SWATH-MS and co-IP results, and the possible role of CAPN5 within such complexes. The possible involvement of CAPN5 in protein quality control is relevant to NIV, as defects in protein quality control have been implicated in inherited retinal disorders. Proteomic data are available via ProteomeXchange with identifier PXD068008.
