Intramedullary Plate Fixation and Viable Bone Allografting in a Complex Intra-articular Distal Radius Fracture Nonunion: A Case Report.

In this report, we detail a 69-year-old female who sustained a comminuted intra-articular left distal radius fracture that failed to heal with bridge plate fixation. Given the patient's poor subchondral bone stock and refusal of bone autograft, we designed a construct using a dorsal spanning plate and an intramedullary fragment-specific plate as a volarly placed strut in combination with viable bone allograft and cancellous bone chips to treat this nonunion. This case demonstrates an option for distal radius non-union treatment and highlights the importance of ingenuity that orthopedic surgeons should demonstrate when trying to accommodate patients' wishes.

A case report of a distal radius fracture treated with a dorsal spanning plate augmented with fragment specific fixation.

Dorsal spanning plates are frequently utilized to manage comminuted intra-articular distal radius fractures, but there is little literature on combining them with augmented fixation in complex cases. We present a 43-year-old man who fell 5 ft onto his outstretched right hand. On examination, there was gross swelling and tenderness of the right wrist with no neurovascular deficit. Radiographs confirmed a comminuted intra-articular displaced distal radius fracture. He was treated with a dorsal spanning plate fixation combined with radiostyloid and volar buttress plates. Follow-up at 2 months showcased intact hardware with good fracture healing. The dorsal spanning plate was removed 4 months after the procedure with radiographs demonstrating adequate alignment and healing without failure. The patient reported no complaints and minimal functional disability. We highlight a case of augmenting a dorsal spanning plate with fragment-specific plate fixation for a comminuted intra-articular displaced distal radius fracture.

Antineuropathic Pain Management After Orthopedic Surgery: A Systematic Review.

Background: The opioid crisis has become a present concern in the medical field. In an effort to address these complications, antineuropathic pain medications have been considered as alternatives to prescribed opioids. Objective: This review focuses on the analgesic effects of neuromodulators, such as gabapentin, duloxetine, and pregabalin, that provide room for less dependence on narcotic analgesics following orthopedic surgery. Methods: During the database searches, 1,033 records were identified as a preliminary result. After duplicates were removed, an initial screen of each article was completed which identified records to be removed due to absence of a full-text article. Articles were excluded if they were not either prospective or retrospective, showcased an irrelevant medication (such as tricyclic antidepressants) which are not pertinent to this review, or deemed to be unrelated to the topic. Results: Ultimately, 19 articles were selected. Three different drugs, gabapentin, pregabalin, and duloxetine, were analyzed to compile data on the effectiveness of preventing opioid overuse and addiction following hand surgery. This review identifies potential evidence that peri-operative gabapentin, pregabalin, and duloxetine administration decreases post-operative pain and lowers opioid dependency. Conclusion: Gabapentin, pregabalin, and duloxetine have potential to further decrease post-operative pain and lower opioid dependency. This review creates an opening for further research in hand surgery to assess an updated protocol for pain management to reduce opioid dependency.

Histopathologic Analysis of a Recalcitrant Calcaneal Wound Treated Using a Synthetic Hybrid-scale Fiber Matrix.

Traditionally, full-thickness wounds with exposed structures are treated with flap coverage or dermal regenerative templates. Most dermal regenerative templates are biologic in origin, but recently synthetic options have become available. One such product is a synthetic hybrid-scale fiber matrix (SHSFM). In this case, SHSFM was used to treat a recalcitrant calcaneal wound. After the wound granulated, it was biopsied, and histopathologic analysis was conducted. A 16-year-old woman involved in a motor vehicle collision sustained multiple traumatic injuries which were stabilized. Postoperatively, she developed a calcaneal infection and associated wound, which developed into a chronic, nonhealing wound. Failed treatments included removal of hardware, multiple debridements, and advanced wound therapies. An SHSFM was then trialed, which led to granulation of the wound without infection. Despite wound healing, the patient subsequently elected to undergo a below-the-knee amputation due to pain and functional disability from posttraumatic ankle arthritis. The heel was biopsied at the time of amputation for analysis. Pathologists noted excellent granulation tissue formation and complete coverage of the wound surface area and 75% of the wound depth, which included epithelialization and decreasing inflammation at wound edges. Collagen deposition and numerous interspersed blood vessels were present. Foreign material and bacteria were absent. No osteomyelitis was observed. This analysis provided the opportunity to investigate the in vivo regenerate from a novel synthetic SHSFM. Given the uniqueness and challenges presented in this case, the usage of this relatively new product warrants further investigation with larger populations and assorted wound etiologies.

Factors Influencing Compliance to Follow-up Visits in Orthopaedic Surgery.

BACKGROUND: Orthopaedic procedures require postoperative follow-up to maximize recovery. Missed appointments and noncompliance can result in complications and increased healthcare costs. This study investigates the relationship between patient postoperative visit attendance and the distance traveled to receive care. MATERIALS AND METHODS: A retrospective review of all surgeries performed by a single orthopaedic surgeon in 2019 at level 1 trauma center in a midsized city serving a largely rural population was completed. We excluded patients who underwent another subsequent procedure. Distance to care and time traveled were determined by the patient's address and the clinic address using Google Maps Application Programming Interface. Other variables that may affect attendance at follow-up visits were also collected. Univariate and multivariate logistic regression was done with purposeful selection. RESULTS: We identified 518 patients of whom 32 (6%) did not attend their first scheduled follow-up appointment. An additional 47 (10%) did not attend their second follow-up. In total, 79 patients (15%) did not attend one of their appointments. Younger age, male sex, Black or African American race, self-pay, Medicaid insurance, accident insurance, and increased distance were individual predictors of missing an appointment. In the final multivariate logistic regression model, male sex (OR 1.74), Black or African American race (OR 2.78), self-pay (OR 3.12), Medicaid (OR 3.05), and traveling more than 70 miles to clinic (OR 2.02) markedly predicted missing an appointment, while workers' compensation (OR 0.23) predicted attendance. DISCUSSION: Several nonmodifiable patient factors predict patient noncompliance in attending orthopaedic postoperative visits. When patients are considered at high risk of being lost to follow-up, there may be an opportunity to implement interventions to improve follow-up rate and patient outcomes, minimize patient costs, and maximize profitability for the hospital.

The effect of smoking on open carpal tunnel release recovery.

INTRODUCTION: This study examines the relationship between smoking status and surgical outcomes in open carpal tunnel release. Smoking status has previously been correlated with orthopedic surgical complications unless smoking cessation occurs at least 4 weeks prior to surgery; however, the effect of smoking on open carpal tunnel release has not been specifically examined. METHODS: This study is a retrospective review of patient charts over the last 5 years (n = 131). Smoking status was determined at the time of carpal tunnel release from the patients' charts. Patients were dichotomized as smokers (n = 58) or non-smokers (n = 73). Data comprised preoperative pain, postoperative pain at 2 and 6 weeks, postoperative wrist stiffness, wound healing time, and infection status. Data were compared on chi square, Fisher exact, and one-sided Fisher exact tests. RESULTS: Infection rates were significantly higher in smokers. Postoperative numbness and wrist stiffness were also significantly higher in smokers. Smokers reported higher postoperative pain scores at 2 and 6 weeks. Non-smokers were also significantly more likely to report complete pain resolution at 6 weeks. DISCUSSION: In the present study smoking was associated with surgical outcome complications in open carpal tunnel release. This could be attributed to immune system suppression or to poor wound healing, both of which are known side-effects of smoking. Pain scores 6 weeks post-surgery were significantly higher in smokers than in non-smokers. Smokers undergoing open carpal tunnel release need to understand the risk of surgical complications and should consider smoking cessation to optimize their chances of successful surgery. CONCLUSION: Patients who were active smokers showed poorer recovery from open carpal tunnel surgery than non-smoking patients.

Outcomes of Threaded Intramedullary Headless Nail Fixation for Metacarpal Fractures.

Metacarpal fractures are common and may require operative treatment; however, there is no gold standard fixation technique. K-wires are used for simplicity and flexibility but require immobilization and can lead to complications. Dorsal plating provides greater stability than K-wires but is subject to its own limitations. Intramedullary threadless nails have reduced time to union and improved range of motion (ROM) but may not provide the stability of plating. Intramedullary screws allow rapid return to activity and increased stability; however, compression forces may shorten metacarpals, producing non-anatomic reduction. The ExsoMed INnateTM threaded intramedullary nail (ExsoMed, Aliso Viejo, CA, USA) was developed with tall threads, a diameter fitting the metacarpal canal cortical purchase, stability, and no compression to prevent fracture displacement and shortening. We designed a prospective study to evaluate INnateTM nail fixation in metacarpal fractures. Visual analog scale (VAS) pain score, total active motion (TAM), radiographic union, and return to normal activity were recorded at each postoperative visit. Descriptive statistics were performed for endpoints. Fifty-eight patients were included with a median age of 38.7 years. The INnateTM nail was used in 80 fractured metacarpals. The 4th and 5th metacarpals were most frequently involved. The most common mechanisms of injury were blunt trauma and motor vehicle collisions. Approximately 31% of patients had multiple, concurrent fractures (16 patients required two nails; two required three nails). The mean follow-up was 9.9 weeks. The mean time to radiographic union was 9.1 weeks. The final visual analog scale (VAS) pain score was 1.1. The mean time to return to work and/or normal activities was 9.7 weeks, and the mean percentage of normal activity resumed was 89.1%.

Elevated Hemoglobin A1c and the Risk of Postoperative Complications in Elective Hand and Upper Extremity Surgery.

BACKGROUND: Studies addressing the utility of hemoglobin A1c (HbA1c) levels in predicting surgical complications have reported mixed results. In practice, many surgeons use HbA1c cutoffs to determine a patient's eligibility for elective surgery. The literature is especially limited in evaluating HbA1c as a risk factor in elective hand and upper extremity surgery. This study aims to evaluate the association of elevated HbA1c levels with the risk of postoperative complications in elective hand and upper extremity surgeries. METHODS: We performed a chart review of patients who underwent these elective operations performed by a single surgeon at a single institution. The outcomes of 930 surgeries were collected up to three months postoperatively, 334 of which had pre or postoperative HbA1c levels recorded. All 930 surgeries were evaluated for association between diabetes mellitus (DM) and complication rates using Fisher's exact test, absolute risk, odds ratio, and regression analysis. RESULTS: DM alone was not associated with an increased risk of postoperative complications. In diabetic patients with both diagnosed DM and HbA1c > 10%, the absolute risk of complications was significantly higher. None of the other HbA1c categories (between 6.5% and 10%) were associated with significantly higher odds of complications in patients with diagnosed DM. CONCLUSIONS: In the context of elective hand and upper extremity surgery, glycemic control (measured by HbA1c) should be included as an element of the surgical preparedness algorithm, rather than an independent disqualifying factor.

The Effect of Body Mass Index on Open Carpal Tunnel Release Recovery.

Purpose: The purpose of this study was to determine whether a relationship exists between body mass index (BMI), specifically obesity, and surgical outcomes for open carpal tunnel release. Obesity is correlated with increased incidence of carpal tunnel syndrome; however, the effect of obesity on after release recovery has not been examined. Methods: This study used a retrospective review of patient charts (n = 142). BMI was calculated based on height and weight measurements, and patients were grouped based on their BMI into the following categories: healthy BMI (18.5-24.9 kg/m2), overweight (25-29.9 kg/m2), obesity class one (30-34.9 kg/m2) (OB1), obesity class (2 35-39.9 kg/m2) (OB2), or obesity class three (40+ kg/m2) (OB3). Data were then complied on surgical outcomes by assessing preoperative pain, postoperative pain at 2 and 6 weeks, postoperative joint stiffness, wound healing time, and infection status. Data were analyzed using chi-square analyses and multivariable logistic regression to assess the differences in treatment outcomes while controlling for possible confounding variables. Results: Age at the time of release was found to be inversely correlated with BMI. Healthy BMI patients (n = 19) underwent release at an average age of 59.1 years, whereas OB3 (n = 30) underwent release at an average age of 46.9 years. The odds of improvement in pain were significantly lower in all three obesity groups when compared with healthy BMI at both 2 and 6 weeks after operation. Conclusions: Our results indicate that obesity may be positively correlated with earlier incidence of carpal tunnel syndrome requiring surgical intervention. These data also indicate the increased rates of postoperative complications in obese patients, particularly patients with OB3. Patients with OB3 need to understand these risks before undergoing open release. Further study should examine the impact of type 2 diabetes on carpal tunnel release recovery. Clinical relevance: The information included in this study may be used to guide surgeons and patients when considering the effect and potential improvement in outcomes that may come from addressing patient BMI before open carpal tunnel surgery.

Use and efficacy of porcine urinary bladder matrix for tissue regeneration: a review.

Porcine-derived UBM, a type of acellular ECM, has demonstrated clinical utility for tissue repair and regeneration across various body systems. UBM acts as a full-thickness, exogenic skin substitute and scaffolding for soft tissue reconstruction while mimicking the function and properties of human ECM. This review presents an overview of the current literature evaluating UBM's clinical and preclinical utility across a broad range of applications. A compilation of studies of human and animal patients with a multitude of tissue defects resulting from various pathologic or injurious processes were systematically reviewed. The types of reconstructions included were categorized by the following surgical domains: abdominal wall; cardiothoracic and pulmonary; gastrointestinal; neurosurgery; oral and maxillofacial; otolaryngology or head and neck; ophthalmology; orthopedic or plastic or orthoplastic surgery; burn and wound care; and urology and gynecology. This systematic review illustrates that UBM may perform as well as or better than other ECM mimetics across various parameters, including reduced time to definitive wound closure, recurrence of wound, infection and/or complication rates, and immunogenic transplant rejection; reduction in overall cost burden to the patient, improved patient satisfaction, and ease of use and maintenance for providers; increased cellular recruitment, invasion, differentiation, and proliferation; and increased repair and regeneration of tissue. This tissue regeneration tends to be more functionally, mechanically, and histologically similar to native tissue through tissue-specific functional remodeling and maturation. This clinical outcome can be seen in various tissue types, levels of injury, and/or defect severity. UBM also proves valuable because of its ability to be used off-the-shelf in surgical, nonsurgical, or office and in-the-field treatment settings.

Flexor tenotomies for the treatment of bilateral wrist contracture after traumatic brain injury: A case report.

Traumatic brain injuries have the potential to cause the development of long-term complications. We aim to show that the use of flexor tenotomies in the treatment of flexion contractures following traumatic brain injury is a viable solution.

Arthrex Mini Tightrope Fixation for Chronic Distal Radioulnar Joint Instability.

Chronic distal radioulnar joint (DRUJ) instability is a complex clinical condition that is difficult to treat. Currently, there is no gold standard treatment. We present a novel technique using Arthrex Mini Tightrope for DRUJ stabilization. In this case series, a 1.6 mm K-wire was passed transversely through the distal ulna and radius. The Mini Tightrope was inserted into the end of the K-wire and pulled through the bone tunnels. Appropriate tension was achieved to stabilize the joint according to individual laxity comparable to the contralateral side. Five patients (3 males and 2 females) comprised this pilot series, with a mean age of 27.1 years. All sustained a traumatic injury at an average of 12.4 months before surgery (range: 5 to 32 mo). In addition, 3 patients had central triangular fibrocartilage complex tears treated with arthroscopy at the time of Mini Tightrope placement. While one patient was lost to follow-up after 7 weeks postoperative due to incarceration, 4 patients demonstrated coronal and sagittal stability in the context of DRUJ motion and a satisfactory range of motion. The mean time for the return to work for the two patients who were laborers or normal activity postoperatively was 5.2 weeks (range: 1 to 16.4 wk). Unrestricted activity was generally allowed 8 weeks postoperatively but varied by patient. The same 4 patients underwent hardware removal at an average of 31 weeks (range: 15 to 44 wk). Although this is only a pilot series, this suggests that temporary Mini Tightrope stabilization of the DRUJ may be a viable solution while upholding the benefits of minimally invasive surgery.

Patient-Reported Outcomes and Provocative Testing in Peripheral Nerve Injury and Recovery.

Background Peripheral nerve function is often difficult to assess given the highly variable presentation and subjective patient experience of nerve injury. If nerve assessment is incomplete or inaccurate, inappropriate diagnosis and subsequent treatment may result in permanent dysfunction. Objective As our understanding of nerve repair and generation evolves, so have tools for evaluating peripheral nerve function, recovery, and nerve-related impact on the quality of life. Provocative testing is often used in the clinic to identify peripheral nerve dysfunction. Patient-reported outcome forms provide insights regarding the effect of nerve dysfunction on daily activities and quality of life. Methods We performed a review of the literature using a comprehensive combination of keywords and search algorithms to determine the clinical utility of different provocative tests and patient-reported outcomes measures in a variety of contexts, both pre- and postoperatively. Results This review may serve as a valuable resource for surgeons determining the appropriate provocative testing tools and patient-reported outcomes forms to monitor nerve function both pre- and postoperatively. Conclusion As treatments for peripheral nerve injury and dysfunction continue to improve, identifying the most appropriate measures of success may ultimately lead to improved patient outcomes.

A Consensus Approach for Targeted Muscle Reinnervation in Amputees.

Amputations have been performed with few modifications since the dawn of surgery. Blood vessels are ligated, bones are shortened, and nerves are cut. In a percentage of people, this can result in severe neuropathic, residual limb, and phantom limb pain. Targeted muscle reinnervation is a surgical procedure initially conceived to optimize function for myoelectric prostheses in amputees. Recently, it has been adopted more widely by surgeons for the prevention and treatment of neuropathic pain. Perhaps as a function of its relatively recent development, many authors perform this operation differently, and there has been no overall agreement regarding the principles, indications, technical specifics, and postoperative management guidelines. This article is written as a consensus statement by surgeons focused on the treatment of neuropathic pain and those with extensive experience performing targeted muscle reinnervation. It is designed to serve as a roadmap and template for extremity surgeons to consider when performing targeted muscle reinnervation.

Radiographic Assessment of Bilateral Asymmetry in the Upper Extremities of Living Humans.

Objective Injuries resulting from trauma or tumor resection may cause length alterations in the bones of the upper extremities (UE) requiring reconstruction. Direct contralateral bone is often used to determine the appropriate length for reconstruction but fails to account for potential asymmetry. Given the paucity of data assessing asymmetry in living populations and the need for accurate length approximation, we developed a study evaluating UE long bone asymmetry using radiographic imaging in living subjects. Methods Bilateral X-ray images previously obtained for traumatic injury or chronic osseous conditions were retrospectively collected for adult subjects (ages 18-81). After screening, 61 patients met the inclusion criteria: 28 radii, 29 ulnae, and 19 humeri. Three serial measurements were taken, and the median was used for subsequent analysis. Wilcoxon signed-rank tests were performed to assess differences in contralateral bone lengths. Bootstrapping was utilized to obtain sample sizes of 200, 500, and 1000 for each bone. Results The difference in mean absolute length was 27.0 mm for the humerus, 8.6 mm for the radius, and 7.5 mm for the ulna. Neither the left side nor the right side was significantly longer for any bone. In 57.9% (11/19) of patients, the right humerus was longer than the left; in 60.7% (17/28), the right radius was longer than the left; and in 48.3% (14/29), the right ulna was longer than the left. All other measurements showed the left was longer than the right. Wilcoxon signed-rank tests did not find significant differences between contralateral pairs in any direct measurement group. In bootstrap samples, significant differences in length (p ≤ 0.05) were seen in all samples (n = 200, 500, and 1000) for both humerus and radius but only the 1000 sample group for the ulna. Conclusions Direct contralateral measure may be an appropriate method of length estimation for the humerus, radius, and ulna in post-industrial humans.

Avive Soft Tissue Membrane Improves Outcomes of Revision Upper-extremity Nerve Decompression Surgery.

Revision nerve decompression remains a challenge for surgeons. Avive Soft Tissue Membrane is processed human umbilical cord membrane that may reduce inflammation and scarring, thereby improving tissue gliding. Although synthetic conduits have been reported in revision nerve decompression, the use of Avive has not. Methods: Prospective study of revision nerve decompression with Avive application. VAS pain, two-point discrimination, Semmes-Weinstein, pinch and grip strength, range of motion, Quick Disability of Arm, Shoulder & Hand (QuickDASH), and satisfaction were recorded. Using a propensity-matched cohort, VAS pain and satisfaction were retrospectively collected to compare with cohort outcomes. Results: In the Avive cohort, 77 patients (97 nerves) were included. Mean follow-up was 9.0 months. Avive was applied to the median nerve in 47.4%, ulnar nerve in 39.2%, and radial nerve in 13.4%. VAS pain was 4.5 preoperatively and 1.3 postoperatively. S4 sensory recovery was achieved in 58% of patients, S3+ in 33%, S3 in 7%, S0 in 2%, and improvement from baseline in 87%. Strength improved in 92%. Mean total active motion was 94.8%. Mean QuickDASH score was 36.1, and 96% reported improved or resolved symptoms. Preoperative pain was not significantly different between Avive cohort and controls (P = 0.618). Postoperative pain was significantly lower in cohort patients (1.3 ± 2.2 versus 2.7 ± 3.0, P = 0.001). In the Avive cohort, more had improved or resolved symptoms (P < 0.0001). Clinically important improvement in pain was reported in 64.9% of Avive group patients versus 40.8% of controls (P = 0.002). Conclusion: Avive contributes to improved outcomes in revision nerve decompression.

Threaded intramedullary headless nail fixation for fractures requiring carpometacarpal stabilization.

Carpometacarpal (CMC) fracture-dislocations are uncommon hand injuries, with few studies available regarding their treatment. The current operative treatment options include fixation with K-wires, mini-screws, or plates, though there is no standardized approach because of varying injury patterns and complications associated with each device. The INnate™ threaded intramedullary nail is a relatively novel treatment option that has shown promise in metacarpal fracture fixation by facilitating faster mobilization and recovery with enhanced rotational stability and no compression to prevent fracture displacement and shortening. This study assesses the efficacy of the INnate™ nail for fixation of CMC fracture-dislocations of the second through fifth joints. Nine patients with fourteen CMC fracture-dislocations treated with the INnate™ nail at the University Medical Center between 2019 and 2021 were enrolled in the study. We evaluated postoperative outcomes in terms of pain, total active range of motion (TAM), and return to normal activities. Of the nine patients, seven returned for follow-up. The average time to radiographic union was 11.5 weeks. At final follow-up, no patient reported pain (n = 6). Four patients had 100% TAM, 1 had 95% TAM, and 1 had 25% TAM. The average percentage of normal activity resumed was 84.0% (n = 5). No significant complications were reported. One patient had a dorsal spanning plate; hence, we were unable to record outcomes measures regarding the CMC injury. An additional patient had diminished ROM of the injured hand, but his last follow-up was only 1 month postop. Our pilot data overall suggest that the INnate™ threaded intramedullary nail has the potential to improve treatment algorithms for CMC fracture-dislocations.

Carbapenem-Only Combination Therapy against Multi-Drug Resistant Pseudomonas aeruginosa: Assessment of In Vitro and In Vivo Efficacy and Mode of Action.

The aim of the study was to determine the efficacy of carbapenem-only combination treatments derived from four approved drugs (meropenem, doripenem, ertapenem and imipenem) against a MDR strain of P. aeruginosa in a Galleria mellonella larvae infection model. G. mellonella larvae were infected with P. aeruginosa NCTC 13437 (carrying the VIM 10 carbapenamase) and the efficacy of the six possible dual, four triple, and one quadruple carbapenem combination(s) were compared to their constituent monotherapies. Four of these combinations showed significantly enhanced survival compared to monotherapies and reduced the bacterial burden inside infected larvae but without complete elimination. Bacteria that survived combination therapy were slower growing, less virulent but with unchanged carbapenem MICs-observations that are consistent with a persister phenotype. In vitro time-kill assays confirmed that the combinations were bactericidal and confirmed that a low number of bacteria survived exposure. Mass spectrometry was used to quantify changes in the concentration of carbapenems in the presence of carbapenemase-carrying P. aeruginosa. The rate of degradation of individual carbapenems was altered, and often significantly reduced, when the drugs were in combinations compared with the drugs alone. These differences may account for the enhanced inhibitory effects of the combinations against carbapenem-resistant P. aeruginosa and are consistent with a 'shielding' hypothesis. In conclusion, carbapenem combinations show promise in combating MDR P. aeruginosa and are worthy of additional study and development.

Assessment of Motor Function in Peripheral Nerve Injury and Recovery.

Introduction: Peripheral nerve injuries can be difficult to diagnose, treat, and monitor given their highly variable presentation. When the status of nerves is not accurately assessed, treatment may be delayed or overlooked and can result in lasting functional deficits. As our understanding of nerve repair and generation evolves, so will tools for evaluating both the functional and morphological status of peripheral nerves. Objective: There is currently no single article which provides a detailed, comprehensive view of the literature comparing the clinical utility of various assessment modalities. Furthermore, there is no consensus on the optimal assessment algorithm for peripheral nerve injuries. Methods: We performed a literature review using a comprehensive combination of keywords and search algorithm. The search was focused on clinical data regarding the assessment of peripheral nerves Results: This review may help to determine the appropriate tools that are currently available for monitoring nerve function both pre and postoperatively. Additionally, the review demonstrates possible roles and areas of improvement for each tool used to assess motor function. Conclusion: As surgeons work to improve treatments for peripheral nerve injury and dysfunction, identifying the most appropriate existing measures of success and future directions for improved algorithms could lead to improved patient outcomes.

Gunshot Wounds: Ballistics, Pathology, and Treatment Recommendations, with a Focus on Retained Bullets.

As the epidemic of gunshot injuries and firearm fatalities continues to proliferate in the United States, knowledge regarding gunshot wound (GSW) injury and management is increasingly relevant to health-care providers. Unfortunately, existing guidelines are largely outdated, written in a time that high-velocity weapons and deforming bullets were chiefly restricted to military use. Advances in firearm technology and increased accessibility of military grade firearms to civilians has exacerbated the nature of domestic GSW injury and complicated clinical decision-making, as these weapons are associated with increased tissue damage and often result in retained bullets. Currently, there is a lack of literature addressing recent advances in the field of projectile-related trauma, specifically injuries with retained bullets. This review aims to aggregate the available yet dispersed findings regarding ballistics, GSW etiology, and treatment, particularly for cases involving retained projectiles.
