Efficient synthesis for each of the eight stereoisomers of the iminosugars lentiginosine and 1,4-dideoxy-1,4-imino-D-arabinitol (DAB).

Herein, we describe the efficient, diastereoselective syntheses of the iminosugars 1,4-dideoxy-1,4-imino-D-arabinitol (DAB) 1b, lentiginosine 3a, and the seven stereoisomers of each of these iminosugars starting from 4-benzoyl-6-deoxy-6-iodoglycopyranosides 47 with yields ranging from 38 % to 68 % for the DAB and isomers 1a-1h and from 44 % to 89 % for the lentiginosine and isomers 3a-3h. We also report the syntheses of the eight stereoisomers of the 4-benzoyl-6-deoxy-6-iodoglycopyranosides 47 from commercially available sugars. Key to the iminosugar syntheses is a single multistep reaction that converts the 4-benzoyl-6-deoxy-6-iodoglycopyranosides 47 to a vinyl pyrrolidine through a one-pot zinc mediated reductive elimination, followed by a reductive amination and finally an intramolecular nucleophilic substitution. Strategic selection of the amine utilized in the reductive amination and the functionalization of the intermediate carbon-carbon double bond provides access to a vast array of iminosugars.

Phalangeal fractures: A retrospective comparison of open reduction and internal fixation vs. closed reduction and percutaneous pinning.

The treatment of phalangeal fractures is guided by fracture characteristics, patient factors and surgeon judgment. This study retrospectively compares characteristics of phalangeal fractures treated with closed reduction percutaneous pinning (CRPP) with those of fractures treated with open reduction internal fixation (ORIF) to identify risk factors associated with reoperation. A total of 901 phalangeal fractures were included and treated operatively by either CRPP (748 fractures, 83 â€‹%) or ORIF (153 fractures, 17 â€‹%). Demographics, surgical management, and complication data were collected. Statistical analyses were performed to stratify risk associations and identify potential predictors of reoperation. With multivariate analysis and bootstrapped LASSO regression, fractures addressed by means of ORIF (vs. CRPP), work-related fractures, and open fractures were found to be independently associated with reoperation. These findings can be used to guide patient selection, surgical planning and timing of fracture repair. Level of evidence: Level III, Therapeutic.

Use of Ambient Light Compatible Fluorescence-Guided Surgical Technology for Objective Assessment of Flap Perfusion in Autologous Breast Reconstruction.

BACKGROUND: Decreased autologous flap vascular perfusion can lead to secondary procedures. Fluorescence angiography during surgery reduces the probability of repeat surgery but suffers from interpretation variability. Recently, the OnLume Avata System was developed, which evaluates real-time vascular perfusion in ambient light. This study aims to predict complications in autologous breast reconstruction using measures of relative intensity (RI) and relative area (RA). METHODS: Patients undergoing autologous breast reconstruction underwent intraoperative tissue perfusion assessment using the OnLume Avata System. Post-hoc image annotation was completed by labeling areas of the flap interpreted to be "Well Perfused," "Questionably Perfused," and "Under Perfused." RIs and RAs were calculated for the marked areas. Primary complications of interest were overall complication rate, fat and mastectomy skin flap necrosis, and surgical revision. Logistic regression was applied to determine the odds of developing a complication based on RI and RA for each image. RESULTS: A total of 25 patients (45 flaps) were included. In total, 17 patients (68%) developed at least one complication. Patients who developed any complication (p = 0.02) or underwent a surgical revision for complications (p = 0.02) had statistically lower RI of under-perfused portions of the flap. Patients with greater areas of under-perfused flap had a significantly higher risk of developing fat necrosis (odds ratio [OR]: 5.71, p = 0.03) and required a revision operation (OR: 1.10, p = 0.01). CONCLUSION: Image-based interpretation using the OnLume Avata System correlated with the risk of developing postoperative complications that standard fluorescence imaging systems may not appreciate. This information can benefit surgeons to improve perfusion assessment and intraoperative decision-making.

Reduction cranioplasty for hydrocephalic macrocephaly: a systematic review of surgical outcomes.

OBJECTIVE: Hydrocephalic macrocephaly can result in poor psychosocial development, positioning difficulties, skin breakdown, and poor cosmesis. Although reduction cranioplasty can address these sequelae, the postoperative outcomes, complications, and mortality risk of reduction cranioplasty are not well understood given the rarity of hydrocephalic macrocephaly. Therefore, the primary objective of this systematic review was to evaluate the surgical outcomes of reduction cranioplasty for the treatment of hydrocephalic macrocephaly. METHODS: A systematic review was performed using the PubMed, Scopus, and Web of Science databases while following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Two independent reviewers screened 350 studies; 27 studies reporting surgical outcomes on reduction cranioplasty for hydrocephalic macrocephaly met inclusion criteria. Data on study design, patient demographics, operative details, and surgical outcomes were collected. RESULTS: There were 65 reduction cranioplasties among the 27 included studies. Eighteen (66.7%) studies presented level V evidence, 7 (25.9%) presented level IV evidence, and 2 (7.4%) presented level III evidence. Following reduction cranioplasty, there was improvement in postoperative head positioning in 23 (85.2%) studies, improvement in postoperative cosmesis in 22 (81.5%) studies, and improvement in global postoperative neurological functioning in 20 (74.1%) studies. The median estimated blood loss was 633 mL (range 20-2600 mL). Shunt revisions were the most common complication, reported in 9 (47.4%) of the 19 studies assessing complications. Of the 65 patients, there was a mortality rate of 6.2% (n = 4). CONCLUSIONS: The majority of the included studies reported improvement in head size, head positioning, cranial cosmesis, and global neurological functioning following reduction cranioplasty for hydrocephalic macrocephaly. However, the prevalence of lower-level evidence, risk of blood loss, complications, and mortality indicates the need for a serious discussion of surgical indication, an experienced team, and thorough perioperative planning to perform these complex surgeries.

Predicting Nipple Necrosis with a "Lights-on" Indocyanine Green Imaging System: A Report of Two Patients.

Nipple-areolar complex (NAC) necrosis is a devastating complication in nipple-sparing mastectomies (NSMs) that significantly impacts patient's quality of life. The use of fluorescence angiography for intraoperative assessment of mastectomy skin flap perfusion in NSM has been successfully described and can be utilized to help guide surgical decision-making. Recently, a novel fluorescence-guided surgical imager was developed, OnLume Avata System (OnLume Surgical, Madison, WI), which provides intraoperative evaluation of vascular perfusion in ambient light. In this case report, we describe the use of OnLume fluorescence-guided surgery technology to help aid in clinical decision-making for two breast reconstruction cases with concern for intraoperative nipple hypoperfusion.

Social media analysis of pain outcomes following targeted muscle reinnervation.

AIM: Targeted muscle reinnervation (TMR) was developed to improve myoelectric prosthesis control for amputees; however, it has become an area of interest in pain modulation. Evidences indicate that this procedure alleviates chronic pain in amputees. The primary objective of this study was to use social media analysis to understand patients' post-operative pain, satisfaction, and recovery time after TMR. METHODS: Data were collected from one Facebook group via posts and comments referencing TMR. Posts published between January 1, 2020, and March 24, 2023 were analyzed. Data collected included pain prior to surgery, pain in immediate post-op period, and change in pain after surgery. RESULTS: Forty-three individuals commented on their TMR experience. Among them, 31 had favorable surgical outcomes, 7 felt that the surgery worsened their pain or there was no significant change in their pain levels, and 5 commented during the initial post-operative period. Twenty-four patients described their pain in the immediate post-operative period and all patients said that the post-operative pain was worse than chronic pain. Among the 28 authors who commented on overall reduction in chronic pain, 24 reported that TMR reduced their pain, whereas 4 reported no change or worsened pain. CONCLUSIONS: The number of patients (24) who reported improvement in chronic pain aligns with the results in current literature suggesting that TMR is a viable treatment option for pain management. With the current medical management of similar conditions, up to 80% of patients remain unsatisfied with pain management. This analysis supports the evidence that TMR is an effective treatment for patients experiencing post-amputation pain.

Osteoarthritis Increases the Frequency and Duration of Postoperative Hand Clinic Visits after Carpal Tunnel Release.

Background: Carpal tunnel syndrome affects up to 6% of the general population, and surgical intervention is often required to ameliorate symptoms. Osteoarthritis (OA) is a common condition that often coexists with carpal tunnel syndrome. We hypothesized that patients with preexisting OA use more healthcare resources after carpal tunnel release (CTR) than patients without arthritis. Methods: This was a retrospective cohort study at a single academic center between January 1, 2018 and November 1, 2021. Patients who underwent CTR were included. Preoperative carpal tunnel symptoms, diagnostic tests, medications, and concomitant OA were abstracted. Hand, wrist, and basal joint arthritis were specified. The primary outcome was healthcare utilization represented by duration and frequency of hand clinic and occupational therapy (OT) follow-up. In total, 312 hands were included. Multivariable analysis was performed. Results: The average duration of hand clinic follow-up among patients without arthritis was 25.3 days compared with 87.1 days for patients with any arthritis (P = 0.0375) and 172 days for patients with wrist arthritis (P = 0.012). The average number of postoperative surgeon visits was increased in patients with hand arthritis, with an average of 2.3 visits versus 1.34 visits for patients without arthritis (P = 0.003). Both the number of OT visits and the duration of OT follow-up did not differ between cohorts. Conclusion: After CTR, patients with preexisting OA use more healthcare resources than patients without OA.

Modified Frailty Index predicts postoperative complications following adult-acquired buried penis surgery: A retrospective cohort study.

BACKGROUND: Given that patients with morbid obesity are predisposed to frailty, we sought to determine whether the 5-Factor Modified Frailty Index (mFI-5) predicts postoperative complications following surgery for adult-acquired buried penis, and secondarily, to compare the mFI-5 to body mass index (BMI) and American Society of Anesthesiologists (ASA) status as preoperative risk stratification measures. METHODS: We included all patients who underwent surgical management for adult-acquired buried penis at an academic Level I trauma center between 2015 and 2023. A manual chart review was performed to collect data on patient demographics, modified frailty index variables, intraoperative data, postoperative outcomes, and complications. RESULTS: A total of 55 patients underwent surgical repair of adult-acquired buried penis, with 26 experiencing postoperative complications (47.3%). Univariable regression analyses revealed that the mFI-5 was a significant predictor of postoperative complications (odds ratio [OR] 3.40, 95% confidence interval [CI]: 1.56-7.42, p = .002), ongoing postoperative urinary problems (OR 2.03, 95% CI: 1.02-4.05, p = .045), patient dissatisfaction with outcomes (OR 3.29, 95% CI: 1.35-8.02, p = .009), and persistent postoperative symptoms (OR 2.42, 95% CI: 1.10-5.35, p = .029). There was no significant association between ASA classification and postoperative complications (OR 1.59, 95% CI:.544-4.63, p = .398). Multivariable analysis demonstrated that the mFI-5 was an independent predictor of postoperative complications (OR 5.34, 95% CI: 1.80-15.9, p = .003) when controlling for BMI and age. CONCLUSION: The mFI-5 is an independent predictor of postoperative complications in patients undergoing surgical repair of adult-acquired buried penis. The simplicity of the index permits efficient preoperative risk stratification of adult-acquired buried penis patients and provides important counseling information that may not be reflected by age or BMI alone.

Sociodemographic Disparities in Craniosynostosis: A Systematic Review.

OBJECTIVE: Given the consequences of delayed treatment and diagnosis of craniosynostosis, this study reviews the literature on sociodemographic risk factors and disparities associated with delayed craniosynostosis treatment. DESIGN: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A literature search of PubMed/Medline and Embase was performed by two independent reviewers. Included studies discussed craniosynostosis health disparities. Demographic characteristics and outcomes were analyzed. SETTING: Not applicable. PATIENTS: Patients with craniosynostosis. INTERVENTIONS: Standard surgical intervention for craniosynostosis. RESULTS: Our literature search yielded 273 studies, of which 18 were included for analysis. Included studies represented data from 31 256 U.S. patients with craniosynostosis. Sixty percent of patients (n = 16 510) were White, 13.8% were Hispanic/Latino, 6.2% were Black/African American, 1.3% were Asian, 0.3% were American Indian or Alaska Native, and 0.1% were Native Hawaiian or Pacific Islander. Average age at surgery was 6.36 months for White patients, 10.63 months for Black patients, and 9.18 months for Hispanic patients. Minority racial and/or ethnic status was a risk factor for delayed presentation, and increased incidence of open surgery, complication rates, hospital charges, operative time, anesthesia duration, and hospital length of stay. Government-funded health insurance was associated with delayed intervention and increased complications. CONCLUSIONS: Minority craniosynostosis patients experience delays in intervention and increased complication rates. Our findings highlight the importance of expedited and equitable referrals, screenings, and treatment, and the need for a standardized approach to investigating longitudinal demographic and outcomes data in this population.

"The Impact of Neighborhood and Socioeconomic Disparities on Distal Radius Fracture Follow-Up Adherence: A Retrospective Cohort Study".

BACKGROUND: The aims of this retrospective cohort study were to assess if the Area Deprivation Index (ADI), a novel neighborhood-level socioeconomic disparities metric, is associated with follow-up non-adherence, and secondarily, determine the individual-level socioeconomic factors associated with follow-up non-adherence after treatment of distal radius fractures (DRF). METHODS: We included all patients who underwent non-operative and operative management of DRF at an academic level I trauma center between 2019 and 2021. A manual chart review was performed to collect data on ADI, sociodemographic factors, injury characteristics, conservative and surgical interventions, and healthcare utilization. RESULTS: There was a significant, weak negative Spearman-ranked correlation between ADI state deciles and clinic attendance rates (rs(220) = -.144; [95% CI: -.274, -.009] p = .032). Socioeconomic factors associated with significant differences in clinic attendance rates were having a spouse or partner (protective) (p = .007), Medicaid insurance (p = .013), male sex (p = .023), and current smokers (p = .026). Factors associated with differences in no show rates were having spouse or partner (OR .326; [95% CI: .123 - .867] p = .025), Medicaid insurance (OR 7.78; [95% CI: 2.15 - 28.2] p = .002), male sex (OR 4.09; [95% CI: 1.72 - 9.74] p = .001), and cigarette use (OR 5.07; [95% CI: 1.65 - 15.6] p = .005). CONCLUSIONS: ADI has a weak, negative correlation with clinic attendance rates following DRF treatment. Significant disparities in clinic follow-up adherence exist between patients with different marital status, insurances, sexes, and cigarette use.

A framework for understanding prosthetic embodiment for the plastic surgeon.

Plastic surgeons play a critical role in the management of amputations and are uniquely positioned to improve the lives and functional abilities of patients with limb loss. The embodiment of a prosthesis describes how effectively it replaces a missing limb and is an important aspect of patient care. Despite its importance, the current prosthetics literature lacks a formal definition of embodiment, and descriptions are often vague or incomplete. In this narrative review, we assess the current literature on prosthetic embodiment to explore the main mechanisms of embodiment and how each allows a prosthesis to interface with the human body. In doing so, we provide a comprehensive, holistic framework for understanding this concept.

Forty-Year Follow-Up After Great Toe-to-Thumb Transfer: A Literature Review.

The thumb is a crucial part of the hand, and traumatic thumb amputation is a devastating injury that significantly diminishes hand function. In situations in which replantation is not possible, great toe-to-thumb transfer is a well-established option for reconstruction. Although most studies describe excellent functional outcomes and patient satisfaction, there is a paucity of literature presenting long-term follow-up to determine whether these outcomes are maintained. In this case report, we present a case of great toe-to-thumb transfer performed 40 years ago and evaluate outcomes using validated questionnaires and standardized examination maneuvers. Our results highlight sustained patient satisfaction and excellent functional outcomes decades after the initial reconstruction.

Insurance Status Predicts Hand Therapy Adherence Following Flexor Tendon Repair: A Retrospective Cohort Study".

BACKGROUND: Many patients are not adherent to hand therapy rehabilitation following surgical repair of traumatic flexor tendon injuries, which can negatively affect surgical outcomes and long-term hand function. We aimed to identify the factors that predict patient non-adherence to hand therapy following flexor tendon repair surgery. METHODS: This retrospective cohort study included 154 patients who underwent surgical repair of flexor tendon injuries at a level I trauma center between January 2015 and January 2020. A manual chart review was performed to collect demographic data, insurance status, injury characteristics, and details of the postoperative course including health care utilization. RESULTS: Factors significantly associated with occupational therapy no-shows included Medicaid insurance (OR, 8.35; 95% CI, 2.91 to 24.0; p < 0.001), self-identified Black race (OR, 7.28; 95% CI, 1.78 to 29.7; p = 0.006), and current cigarette smoker status (OR, 2.69; 95% CI, 1.18 to 6.15; p = 0.019). Patients without insurance attended 73.8% of their OT visits and patients with Medicaid attended 72.0% of their visits, which were significantly lower rates than those with private insurance 90.7% (p=0.026 and p=0.001, respectively). Patients with Medicaid were 8 times more likely to seek emergency department care postoperatively than patients with private insurance (p=0.002). CONCLUSIONS: Significant disparities in hand therapy adherence following flexor tendon repair surgery exist between patients with different insurance statuses, races, and tobacco use. Understanding these disparities can help providers identify at-risk patients to improve hand therapy utilization and postoperative outcomes.

Offering No-Cost Cosmetic Revisions: The Experience of an Academic Cosmetic Surgery Program.

Background: The financial principles of a no-cost revision policy and their implications for revision rates are not well understood. Objectives: Therefore, the primary objective of this retrospective study is to report our no-cost revision rates and, secondarily, to survey the cosmetic revision policies of other cosmetic surgery practices and detail the financial principles underpinning no-cost revisions. Methods: All aesthetic surgeries and no-cost revisions performed by the plastic surgeons, oculoplastic surgeons, and facial plastic and reconstructive surgeons at our academic outpatient cosmetic surgery center from January 1, 2016 to June 30, 2022 were identified using procedural codes. Data on the number of surgeries, number of revisions, operative minutes, and time intervals between initial and revision surgeries were collected. A survey was administered to assess the revision policies of similar cosmetic surgery practices. Results: A total of 1491 aesthetic surgeries and minimally invasive procedures were included, and 125 revision procedures were performed (8.4%). Thigh lifts (3, 13.6%), rhinoplasties or septoplasties (25, 15.8%), and otoplasties (3, 27.3%) had the highest revision rates. Three practices (15%) offered cosmetic revisions at no cost, 9 (45%) did not apply a surgeon's fee, 5 (25%) evaluated fees on a case-by-case basis, 1 (5%) offered revisions with an insurance policy, and 2 (10%) cosmetic surgery practices did not offer revisions at a reduced rate. Conclusions: Despite offering revisions at no cost, our revision rates are reasonable for an academic cosmetic surgery practice. The revision policies offered to patients on the private market are varied, but most surveyed practices offer revisions at either a reduced rate or no cost.

Objective Residency Applicant Assessment Using a Linear Rank Model.

OBJECTIVES: Residency applicant assessment is imperfect, with little objectivity built into the process, which, unfortunately, impacts recruitment diversity. Linear rank modeling (LRM) is an algorithm that standardizes applicant assessment to model expert judgment. Over the last 5 years, we have used LRM to assist with screening and ranking integrated plastic surgery (PRS) residency applicants. This study's primary objective was to determine if LRM scores are predictive of match success and, secondarily, to compare LRM scores between gender and self-identified race categories. DESIGN: Data was collected on applicant demographics, traditional application metrics, global intuition rank, and match success. LRM scores were calculated for screened and interviewed applicants, and scores were compared by demographic groups. Univariate logistic regression was used to evaluate the association of LRM scores and traditional application metrics with match success. SETTING: University of Wisconsin, Division of Plastic and Reconstructive Surgery. Academic institution. PARTICIPANTS: Six hundred seventeen candidates who applied to a single institution over 4 application cycles (2019-2022). RESULTS: Using area under the curve modeling, LRM score was the most predictive indicator for match success. With every one-point increase in LRM score, there was an 11% and 8.3% increase in the likelihood of screened and interviewed applicant match success (p < 0.001). An algorithm was developed to estimate the probability of match success based on LRM score. No significant differences in LRM scores were appreciated for interviewed applicant gender or self-identified race groups. CONCLUSIONS: LRM score is the most predictive indicator of match success for PRS applicants and can be used to estimate an applicant's probability of successfully matching into an integrated PRS residency. Furthermore, it provides a holistic evaluation of the applicant that can streamline the application process and improve recruitment diversity. In the future, this model could be applied to assist in the match process for other specialties.

Out-of-scope Cosmetic Surgery: A Review of Malpractice Lawsuits against Nonplastic Surgeons.

The increasing patient demand for cosmetic surgeries and minimally invasive procedures has encouraged physicians without aesthetic surgery training accredited by the American Board of Medical Specialties to provide these services. This systematic review aims to determine the rate of out-of-scope practice in medical malpractice lawsuits involving cosmetic surgery or minimally invasive procedures performed by nonplastic surgeons. Methods: Our systematic review of the Westlaw legal database from 1979 to 2022 included 64 malpractice cases. Inclusion criteria were cosmetic surgeries or minimally invasive procedures in medical malpractice lawsuits not involving board-certified plastic surgeons. Out-of-scope was defined using the procedural competencies established by the American Council for Graduate Medical Education, the Commission on Dental Accreditation, and the Council of Podiatric Medical Education. Data on legal proceedings, provider credentials and board certification, surgical interventions, and legal outcomes were collected. Results: The majority of malpractice cases involving cosmetic surgeries or minimally invasive procedures occurred when providers were practicing out of scope (N = 34; 55.7%). The verdict was ruled in favor of the plaintiff (patient) in 34.4% of cases. Out-of-scope practice occurred most in family/internal medicine, no board certification, and obstetrics/gynecology (N = 4, N = 4, and N = 3, respectively). The most common allegation was permanent injury or disfigurement (N = 21; 21.4%). Plastic surgeons provided expert testimony 44.0% of the time. Conclusion: Our review of the Westlaw legal database suggests that the majority of nonplastic surgeon cosmetic malpractice cases may occur in the setting of out-of-scope practice.

The Price Is Right? An Economic Analysis of Factors Influencing Cosmetic Surgery Prices.

BACKGROUND: Cosmetic surgery is a large portion of practice revenue for many plastic surgeons, and therefore understanding the economic principles of pricing is critical. Although national averages provide a starting point for price determination, they may not reflect specific economic factors. Over the last decade, publicly reported pricing for cosmetic surgery has increased in prevalence, improving price transparency for patients and surgeons alike. OBJECTIVES: This study aims to compare publicly reported prices to national cosmetic surgery averages and identify variables that have the greatest impact on price determination. METHODS: An Internet search was performed with the term "cosmetic surgery, price" for practices that publicly reported cosmetic surgery prices. Publicly reported prices were compared to national averages generated from The Aesthetic Society's Aesthetic Society Plastic Surgery National Databank Statistics. The impact of regional prices, practice type, and surgeon accreditation were analyzed for the most popular cosmetic surgery procedures. RESULTS: Sixty-six practices were identified that reported cosmetic surgery pricing information. Publicly reported prices were significantly higher for all surgical procedures except nipple procedures, excision of (excess) skin, fat grafting, fat harvest, and lip enhancement. Facility/operating room fees (n = 38) and anesthesia fees (n = 34) were the most common components included in a price, after surgeons' fees (n = 66). A significant price difference was appreciated when separating practices by region for all procedures except breast augmentation (P = .074) and liposuction (P = .088). CONCLUSIONS: Publicly reported prices provide greater insight than national averages into specific pricing factors and strategies that can be employed when setting surgical prices.

The Anatomy of a Malpractice Lawsuit.

Medical malpractice lawsuits can be a source of emotional, physical, and financial distress for both providers and patients. A thorough understanding of the medical malpractice process's history and current landscape will help providers navigate malpractice challenges. Given the impact and prevalence of medical malpractice, in this paper, the authors sought to dissect the intricate anatomy of a medical malpractice lawsuit. This includes a comprehensive and detailed report of tort reform, the criteria of a medical malpractice suit, and a description of the court proceedings. In addition, the authors also performed an extensive review of the medicolegal literature and have provided recommendations for healthcare providers to avoid these lawsuits in their practice.

Epidemiology and Fracture Patterns of Traumatic Phalangeal Fractures.

Background: Despite the relatively high incidence of phalangeal fractures, there is an imperfect understanding of the epidemiology and anatomical distribution of these fractures. This study describes the patient characteristics, anatomic distribution, and detailed fracture patterns of phalangeal fractures among a large adult cohort in the United States. Methods: A retrospective study was performed among patients with phalangeal fractures in the United States between January 2010 and January 2015. Included patients were 18 years old or older and had a diagnosis of a phalangeal fracture. A total of 2140 phalangeal fractures in 1747 patients were included, and a manual chart review was performed to collect epidemiological and radiographic information. Fractures were classified based on location and fracture pattern. Results: The median age at the time of injury was 45 years (interquartile range, 30-57), and 65% of patients were men. The small finger had the highest incidence of fractures (26%) followed by the ring finger (24%). Distal and proximal phalanges demonstrated the highest incidence of fractures at 39% each. The dominant hand was affected in 44% of cases. Eighteen percent of fractures were due to a work-related trauma mechanism, and the most common mechanism of injury was blunt trauma (46%). Conclusion: This study provides a detailed overview of the anatomic distribution and fracture patterns of phalangeal fractures in an adult US population and, thus, may aid hand surgeons treating these injuries.

Phalangeal Fractures Requiring Vascular Reconstruction: Epidemiology and Factors Predictive of Reoperation.

BACKGROUND: Demographic information related to phalangeal fractures that undergo simultaneous vascular repair, as well as their complication and reoperation profiles, remain incompletely understood. This study aimed to examine the patient and fracture characteristics influencing the outcomes after these injuries in a large Unites States adult patient cohort and to identify risk factors associated with unplanned reoperation of these fractures. METHODS: A retrospective study was performed, identifying 54 phalangeal fractures in 48 patients; all fractures were also associated with vascular injuries requiring repair. Patients with digital amputations were excluded. A manual chart review was performed to collect epidemiologic, radiographic, and surgical outcome information. RESULTS: The incidence of phalangeal fractures undergoing vascular repair was higher in the non-dominant hand, middle finger, proximal phalanx, and phalangeal shaft. Most (52.9%) fractures were due to occupational injury, with the most common mechanism being sharp injuries. More than half of the fractures had a nerve injury, and 13% required a vein graft for vascular repair. More than half of the fractures required at least one reoperation, most commonly due to "stiffness/tendon adhesion" (50%) and "nonunion or delayed union" (21.4%). In multivariable analysis, thumb (odds ratio [OR]: 35.1, P = .043) and index (OR: 14.0, P = .048) fingers' fractures were found to be independently associated with unplanned reoperation. CONCLUSIONS: Phalangeal fractures requiring vascular repair occurred most often in the occupational setting and more than 50% required at least one unplanned reoperation. Injuries sustained in the thumb and index finger were more likely to undergo unplanned reoperation, which may guide initial treatment decision-making and postoperative follow-up.
