Abstract
There have been dwindling numbers of replantations in the United States. Despite the advocacy for centralization in hand trauma, the fundamental landscape and attitudes of surgeons toward replantation have remained lackluster. There is growing and substantial evidence to demonstrate the superior outcomes of replantation in comparison to revision amputation in most scenarios. This article aims to delve into the factors contributing to the decreasing numbers of replantations and proposes strategies to overcome this issue.

Abstract
PURPOSE Digital replantation is a technically difficult microsurgery requiring significant surgical skill. The aim of this study was to investigate postoperative outcomes associated with the surgical learning curve for microvascular digital replantation. METHODS A prospectively maintained surgical database of consecutive patients who underwent digital replantation from 2002 to 2012 was reviewed. All cases were performed by a single surgeon and began immediately after the surgeon's fellowship. A total of 46 patients were identified. Outcomes of digital replantation were tested for association with time since fellowship, total microvascular operative experience, and location and type of injury. RESULTS Overall, 38/46 (82.6%) of patients underwent a successful digital replantation. There was a significant difference between survival percentages over the years (p=0.04), with improvement seen over time. Total microvascular experience was significantly associated with successful outcomes (p<0.001). After 100 hours of microvascular experience, there was a significant increase in the survival odds ratio (OR 8.5, 95% CI 1.5-47.9). Crush and thumb injuries were more likely to have detrimental outcomes. CONCLUSIONS There was marked improvement in replant survival over time, with a significant increase in odds of survival after 100 hours of microvascular experience. One hundred operating hours under the microscope occurred around 2 years in practice for this high-volume surgeon. There is strong evidence that a steep learning curve occurs in microvascular digit replantation surgery.

Abstract
The importance of informed consent and the value of shared decision-making in hand surgery are well-established and particularly critical in the setting of digit amputation when considering replantation. Informed consent requires an understanding of not only the immediate and long-term risks and benefits of surgery, as well as the risks and alternatives involved, but also the capacity of the patient to make a medical decision. However, patients who have acutely sustained a disfiguring trauma are often in distress and may not fully process the consent discussion. Digit replantation is an "elective emergency"-the decision must be made immediately but is not lifesaving-which poses a difficult dilemma: are surgeons acting in patients' best interests by pursuing replantation if we engage those patients in informed consent discussions when they may not have capacity? This article explores the relevant bioethical principles associated with digit replantation, summarizes updated literature regarding informed consent and shared decision-making, and provides recommendations for patient education materials to standardize informed consent discussions for surgeons approaching patients at this unique intersection of considering revision amputation versus replantation.

Abstract
INTRODUCTION A common consideration for replantation success is the ischemia time following injury and the preservation temperature. A classic principle within the hand surgery community describes 12 hours of warm ischemia and 24 hours of cold ischemia as the upper limits for digit replantation; however, these limits are largely anecdotal and based on older studies. We aimed to compare survival data from the large body of literature to aid surgeons and all those involved in the replantation process in hopes of optimizing success rates. METHODS The PubMed database was queried on April 4th, 2023, for articles that included data on digit replantation survival in terms of temperature of preservation and ischemia time. All primary outcomes were analyzed with the Mantel-Haenszel method within a random effects model. Secondary outcomes were pooled and analyzed using the chi-square statistic. Statistical analysis and forest plot generation were completed with RevMan 5.4 software with odds ratios calculated within a 95% confidence interval. RESULTS Our meta-analysis identified that digits preserved in cold ischemia for over 12 hours had significantly higher odds of replantation success than the amputated digits replanted with 0-12 hours of warm ischemia time ( P ≤ 0.05). The odds of survival in the early (0-6 hours) replantation group were around 40% greater than the later (6-12 hours) replantation group ( P ≤ 0.05). Secondary outcomes that were associated with higher survival rates included a clean-cut amputation, increased venous and arterial anastomosis, a repair that did not require a vein graft, and replants performed in nonsmokers ( P ≤ 0.05). DISCUSSION Overall, these findings suggest that when predicting digit replantation success, time is of the essence when the digit has yet to be preserved in a cold environment. This benefit, however, is almost completely diminished when the amputated digit is appropriately maintained in a cold environment soon after injury. In conclusion, our results suggest that there is potential for broadening the ischemia time limits for digit replant survival outlined in the literature, particularly for digits that have been stored correctly in cold ischemia.

Abstract
Background Rodeo is a globally popular sport, with its athletes prone to various types of injuries. There is no systematic review discussing rodeo injuries across all age groups. Purpose To (1) review the published literature on incidence, types of injuries, and factors leading to injuries in rodeo athletes; (2) provide prevention recommendations for health care providers; and (3) identify gaps in the research. Study Design Systematic review; Level of evidence, 4. Methods A comprehensive search of available literature was electronically performed through MEDLINE, Embase, and SPORTDiscus databases using the key terms "rodeo" and "injury" or "trauma" between 1995 and 2021. A systematic review was performed using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, which identified 116 eligible studies. Outcome data included frequency of injuries, risk factors for injury, and types of injury. Results A total of 23 studies met the inclusion criteria (N = 2105 athletes), of which 13 were retrospective studies. In the included studies, the injury rate per competition exposure (CE) ranged from 4.2 to 19.1 injuries per 1000 CE. Sprains and strains accounted for the highest percentage of injury types, ranging from 15% to 34%. The knee was the most common location of injury, making up 11.1% to 17% of injuries. Concussions occurred in up to 15.3% of injuries for all events and up to 77% of injuries in roughstock events. Of all rodeo events reported, bull riding caused the highest percentage of injuries, making up 19.4% to 58.4% of injuries, and bareback had the second highest at 15.3% to 28.8% of injuries. Conclusion There was a high prevalence of various injury types and mechanisms in rodeo. Improved injury surveillance and the introduction of a comprehensive standardized injury reporting system would be helpful in the future prevention, diagnosis, and treatment of rodeo injuries.

Abstract
Purpose Function and cosmesis may be improved by replantation following digital amputation in pediatric patients. However, accurate failure and complication rate estimates may be limited as most pertinent studies reflect single center/surgeon experience and therefore are limited by small sample sizes. The primary aim of this study was to assess the rate of failure (amputation) following pediatric digital replantation. Secondary aims include evaluating the rate of complications and associated resource utilization (intensive care unit stays, readmission rate, and hospital length of stay). Methods Digital replantation patients were identified from 47 pediatric hospitals using the 2004 to 2020 Pediatric Health Information System nationwide database. Using applicable International Classification of Disease 9/10 and Current Procedural Terminology codes, we identified complications after replantation, including revision amputation, infection, surgical complications, medical complications, admission to intensive care unit (ICU), and length of stay. Results Of the 348 patients who underwent replantation the mean age was 8.3 ± 5.1 years, and 27% were female. Mean hospital length of stay was 5.8 ± 4.7 (range, 1-28) days. Of the 53% of patients who required ICU admission, the mean ICU length of stay was 2.4 ± 3.3 days. Failure/amputation after replantation occurred in 71 (20.4%) patients, at a mean of 9.7 ± 27.2 days postoperatively. Surgical complications occurred in 58 (17%) patients, 30-day hospital readmissions occurred in 5.7% of patients, and 90-day readmissions occurred in 6.3% patients. Conclusion The estimated rate of failure following pediatric digit replantation was 20%. Our data on failure and complication rates and associated resource utilization may be useful in counseling pediatric replantation patients and their families and provide an update on prior literature. Level of Evidence IV, Prognosis.

Abstract
The aim of this article is to examine the elements that contribute to effective operation of a specialized replantation center and to provide readers with a general idea of the outcome of replantation services in India. A dedicated high-volume center coupled with a sound referral system is the backbone of replantation services in a country. A retrospective study was done on all patients who visited a level 1 trauma center in India from November 1, 2017, to December 31, 2018, for various amputations. The medical records and digital pictures of these patients were extracted from the records and analyzed. During the study period, 77 replants were performed on 63 patients at our center. Males were 68% of the study, mostly belonging to the 20 to 40 years age group (63%). Thirty-four percent of cases were smokers. Agricultural injuries (49%) were the most common cause of amputation. Finger replantation was the most common type of replantation (82%). The rate of successful replantation was highest for scalp (100%) followed by hand (71%) and thumb (67%). Setting up dedicated replantation services is essential, especially in highly populated areas. Manpower, resources, and a protocol-led approach help in achieving optimum results. A multidisciplinary team approach with round-the-clock availability plays a vital role in intraoperative decision-making and planning postoperative rehabilitation.

Abstract
The ability to perform surgical replantation of individual digits and limbs can provide substantial functional improvement for patients who sustain devastating upper extremity injuries. Defining success in replantation surgery extends beyond the acute period and the binary metrics of survival or loss of the replanted part to include the long-term overall functional outcomes. Functional outcomes include both objective clinical evaluation and patient-reported outcomes. There has been significant variation in the way outcomes following replantation are measured, which inherently leads to heterogeneity in the reported outcome data. Given the variability among outcome measures, we aim to explore the outcomes of replantation surgery, particularly clinical evaluation and patient-reported functional outcomes following replantation.

Abstract
BACKGROUND Ensuring the patency of repaired vessels is pivotal in improving the success rate of digit replantation. There is no consensus on how to best approach postoperative treatment for digit replantation. The influence of postoperative treatment on the risk of failure of revascularization or replantation remains unclear. QUESTIONS/PURPOSES (1) Is there an increased risk of postoperative infection with early discontinuation of antibiotic prophylaxis? (2) How are anxiety and depression affected by a treatment protocol consisting of prolonged antibiotic prophylaxis and administration of antithrombotic and antispasmodic drugs and by the failure of a revascularization or replantation procedure? (3) Are there differences in the risk of revascularization or replantation failure based on the number of anastomosed arteries and veins? (4) What factors are associated with failure of revascularization or replantation? METHODS This retrospective study was conducted between July 1, 2018, and March 31, 2022. Initially, 1045 patients were identified. One hundred two patients chose revision of amputation. In all, 556 were excluded because of contraindications. We included all patients in whom the anatomic structures of the amputated part of the digit were well preserved, and those with an ischemia time for the amputated part that did not exceed 6 hours. Patients in good health without any other serious associated injuries or systemic diseases and those without a history of smoking were eligible for inclusion. The patients underwent procedures that were performed or supervised by one of four study surgeons. Patients were treated with antibiotic prophylaxis (1 week); patients treated with antithrombotic and antispasmodic drugs were categorized into the prolonged antibiotic prophylaxis group. The remaining patients treated with antibiotic prophylaxis for less than 48 hours and no antithrombotic and no antispasmodic drugs were categorized into the nonprolonged antibiotic prophylaxis group. Postoperative follow-up was for a minimum of 1 month. Based on the inclusion criteria, 387 participants with 465 digits were selected for an analysis of postoperative infection. Twenty-five participants with a postoperative infection (six digits) and other complications (19 digits) were excluded from the next stage of the study, in which we assessed factors associated with the risk of failure of revascularization or replantation. A total of 362 participants with 440 digits were examined, including the postoperative survival rate, variation in Hospital Anxiety and Depression Scale scores, the association between the survival rate and Hospital Anxiety and Depression Scale scores, and the survival rate based on the number of anastomosed vessels. Postoperative infection was defined as swelling, erythema, pain, purulent discharge, or a positive bacterial culture result. Patients were followed for 1 month. The differences in anxiety and depression scores between the two treatment groups and the differences in anxiety and depression scores based on failure of revascularization or replantation were determined. The difference in the risk of revascularization or replantation failure based on the number of anastomosed arteries and veins was assessed. Except for statistically significant variables (injury type and procedure), we thought that the number of arteries, number of veins, Tamai level, treatment protocol, and surgeons would be important. A multivariable logistic regression analysis was used to perform an adjusted analysis of risk factors such as postoperative protocol, injury type, procedure, number of arteries, number of veins, Tamai level, and surgeon. RESULTS Postoperative infection did not appear to increase without prolonged use of antibiotic prophylaxis beyond 48 hours (1% [3 of 327] versus 2% [3 of 138]; OR 2.4 [95% confidence interval (CI) 0.5 to 12.0]; p = 0.37). Intervention with antithrombotic and antispasmodic therapy increased the Hospital Anxiety and Depression Scale scores for anxiety (11.2 ± 3.0 versus 6.7 ± 2.9, mean difference 4.5 [95% CI 4.0 to 5.2]; p < 0.01) and depression (7.9 ± 3.2 versus 5.2 ± 2.7, mean difference 2.7 [95% CI 2.1 to 3.4]; p < 0.01). In the analysis based on the failure of revascularization or replantation, the Hospital Anxiety and Depression Scale scores for anxiety (11.4 ± 4.4 versus 9.7 ± 3.5, mean difference 1.7 [95% CI 0.6 to 2.8]; p < 0.01) and depression (8.5 ± 4.6 versus 7.0 ± 3.1, mean difference 1.5 [95% CI 0.5 to 2.5]; p < 0.01) were higher in the failed revascularization or replantation group than in the successful revascularization or replantation group. There was no increase in the artery-related risk of failure (one versus two anastomosed arteries: 91% versus 89%, OR 1.3 [95% CI 0.6 to 2.6]; p = 0.53). For patients with anastomosed veins, a similar outcome was observed for the two vein-related risk of failure (two versus one anastomosed vein: 90% versus 89%, OR 1.0 [95% CI 0.2 to 3.8]; p = 0.95) and three vein-related risk of failure (three versus one vein anastomosed: 96% versus 89%, OR 0.4 [95% CI 0.1 to 2.4]; p = 0.29). Factors associated with failure of revascularization or replantation included the mechanism of injury (crush: OR 4.2 [95% CI 1.6 to 11.2]; p < 0.01, avulsion: OR 10.2 [95% CI 3.4 to 30.7]; p < 0.01). Revascularization had a lower risk of failure than replantation (OR 0.4 [95% CI 0.2 to 1.0]; p = 0.04). Treatment with a protocol of prolonged antibiotics, antithrombotics, and antispasmodics was not associated with a lower risk of failure (OR 1.2 [95% CI 0.6 to 2.3]; p = 0.63). CONCLUSION With proper wound debridement and patency of repaired vessels, prolonged use of antibiotic prophylaxis and regular antithrombotic and antispasmodic treatment may not be necessary for successful digit replantation. However, it may be associated with higher Hospital Anxiety and Depression Scale scores. Postoperative mental status is associated with digit survival. Well-repaired vessels, instead of the number of anastomosed vessels, could be critical to survival and decrease the influence of risk factors. Further research on consensus guidelines that compare postoperative treatment and the surgeon's level of expertise after digit replantation should be conducted at multiple institutions. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
PURPOSE The purpose of this study was to determine if the use of postoperative therapeutic dose intravenous heparin (POTDIVH) was indicated in digital replantation and revascularization by assessing digit survival and complications associated with heparin. METHODS All patients with amputation distal to the carpal tunnel treated at our center from 2004 to 2020 were included for chart review. Digit survival and complication rates were compared between patients who received POTDIVH (group A) and those who did not (group B). Logistic regression analysis and subgroup analysis were conducted. RESULTS A total of 795 patients (1,155 digits) were included in this study (248 patients/374 digits in group A and 547 patients/781 digits in group B). The overall revascularization and replantation success rate was 79.9% in the POTDIVH group and 92.8% in the non-POTDIVH group. In our retrospective regression and subgroup analyses, group A demonstrated increased odds of failure compared with group B and was associated with increased bleeding-related complications. Subgroup analyses stratified by the mechanism of injury and vein grafting also showed a significantly decreased survival in the POTDIVH group. CONCLUSIONS Our retrospective data seem to indicate that heparin in digit replantation and revascularization appears to have no benefit on digit survival across all subgroups, including crush and avulsion injuries, and is associated with a significantly increased rate of complications. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
Introduction Utilize a national pediatric database to assess whether hospital characteristics such as location, teaching status, ownership, or size impact the performance of pediatric digit replantation following traumatic digit amputation in the United States. Materials and Methods The Kid's Inpatient Database (KID) was used to query pediatric traumatic digit amputations between 2000 and 2012. Ownership (private and public), teaching status (teaching and non-teaching), location (urban and rural), hospital type (general and children's), and size (large and small-medium) characteristics were evaluated. Replantations were then divided into those that required subsequent revision replantation or amputation. Fisher's exact tests and multivariable logistic regressions were performed with p <0.05 considered statistically significant. Results Overall, 1,015 pediatric patients were included for the digit replantation cohort. Hospitals that were privately owned, general, large, urban, or teaching had a significantly greater number of replantations than small-medium, rural, non-teaching, public, or children's hospitals. Privately owned (odds ratio [OR]: 1.80; 95% confidence interval [CI]: 1.06-3.06; p = 0.03) and urban (OR: 2.29; 95% CI: 1.41-3.73; p = 0.005) hospitals were significantly more likely to perform replantation. Urban (OR: 4.02; 95% CI: 1.90-8.47; p = 0.0003) and teaching (OR: 2.11; 95% CI: 1.17-3.83; p = 0.014) hospitals were significantly more likely to perform a revision procedure following primary replantation. Conclusion Private and urban hospitals were significantly more likely to perform replantation, but urban and teaching hospitals carried a greater number of revision procedures following replantation. Despite risk of requiring revision, the treatment of pediatric digit amputations in private, urban, and teaching centers provide the greatest likelihood for an attempt at replantation in the pediatric population. The study shows Level of Evidence III.

Abstract
Purpose: Understanding the variables that influence success in digital replant surgery is essential to guide clinical decision-making and to counsel patients. The purpose of this study was to determine the replant success rate and identify predictors of success at our tertiary care centre. Methods: This was a single centre, retrospective cohort study of consecutive patients who underwent digital replantation from January 2000 to September 2018. Adult patients with flexor zone I to III amputations were included. Patient demographics, comorbidities, injury pattern, operative data, and post-operative care were reviewed. The primary outcome was survival of the replanted digit at discharge. Results: A total of 146 patients met inclusion criteria. Of these, 100 had single-digit replants and 46 underwent multi-digit replants for a total of 220 digits. The success rate was 71%. Predictors of success included sharp mechanism of injury (P < .01), incomplete amputation (P < .01), amputation proximal to zone I flexor level (P = .02), post-operative acetylsalicylic acid use (P < .01), absence of leech use (P = .05), and absence of operative re-exploration (P < .01). Daytime replants had similar outcome compared to nighttime replants despite having increased ischemia time (7.9 ± 3.9 hours vs 6.8 ± 2.6 hours, P = .02). However, daytime operative time (7.8 ± 3.7 hours) was significantly shorter than nighttime replant time (9.6 ± 5.9 hours, P = .01). Conclusion: Sharp amputation, intact venous drainage, proximal amputation, and acetylsalicylic acid use were associated with replant survival and are factors to consider when managing patients for digital replantation. Leech therapy and operative re-exploration were associated with poor outcome. Nighttime replants required significantly longer operative time than daytime replants despite similar survival outcome.

Abstract
Importance Recent evidence suggests that select delayed replantation may not adversely affect digit survival; however, whether surgical timing (overnight or daytime) is associated with digit replantation outcomes is unknown. Objective To assess whether digit survival, complication rate, and duration of surgery are associated with time of replantation. Design, Setting, and Participants This retrospective case series study included all replantations performed at a single tertiary referral academic center between January 1, 2000, and August 1, 2021. Data were analyzed between October 2, 2021, and January 1, 2022. Four daytime surgery intervals were selected based on literature review. Daytime replantations started within the intervals whereas overnight replantations began outside the intervals. For each case, the procedure difficulty score and the attending surgeon expertise score were calculated. Logistic and linear regressions adjusting for confounders including procedure difficulty score and expertise score were used to assess surgical timing and outcomes. Participants were adults (aged ≥18 years) undergoing digit replantations between January 2000 and August 2021 with at least 1-month follow-up. Replantation was defined as the reattachment of a completely amputated digit that necessitated anastomosis of both artery and vein. Exposures Daytime or overnight digit replantation. Main Outcomes and Measures Viable replanted digit at 1-month follow-up, number of complications, and duration of surgery. Results A total of 98 patients (mean [SD] age, 39.5 [15.3] years; 136 [93%] men) and 147 digits met inclusion criteria. Overall success rate was 55%. Between 4 pm and 7 am, overnight replantations were associated with 0.4 fewer complications (β, -0.4; 95% CI, -0.8 to -0.1) and 90.7 minutes shorter operative time (β, -90.7; 95% CI, -173.6 to -7.7). A 1-point increase in surgeon expertise score was associated with 1.7 times increased odds of replantation success for all intervals (adjusted odds ratio, 1.7; 95% CI, 1.2 to 2.4; P = .002). There were no differences in digit survival by surgical time. Conclusions and Relevance In this case series study of digit replantations, time of operation was not associated with replantation success. Overnight replantation was associated with fewer complications and shorter duration of surgery compared with daytime surgery. Results of this study suggest that overnight replantations may be performed with outcomes comparable to daytime replantations at a tertiary care academic center.

Abstract
Background The success of digit replantation is mainly based on survival rates. The functional outcome as well as the recovery of sensibility are essential parameters for judging the outcome after digit replantation but have been poorly assessed in previous studies. Patients and methods Forty-eight patients with 56 complete traumatic digit amputations occurring between 2008 and 2013 returned for a follow-up examination, the earliest being 6 months postoperatively. Each patient’s range of motion, fingertip-to-table distance, fingertip-to-palm distance, grip and pinch strengths, static two-point discrimination (2-PD), and Semmes–Weinstein monofilament (SWM) test level were assessed in order to compare functional outcome and recovery of sensibility between successful replantation (n = 19) and primary or secondary amputation (n = 37). Subjective assessments of the pain level and function of the upper extremity were performed using the numerical rating scale and the DASH score, respectively. Results Replanted digits achieved 58% of the median total range of motion of the corresponding uninjured digits. Grip and pinch strength were not significantly different after thumb or finger replantation or amputation. Recovery of sensibility was excellent after replantation, with a median static 2-PD of 5 mm and a reduction of pressure sensibility of two levels of the SWM test compared to the contralateral side. After amputation, the median static 2-PD was also very good, with a median value of 6 mm and a reduction of pressure sensibility of only one level according to the SWM test. There was significantly less pain after replantation at rest (p = 0.012) and under strain (p = 0.012) compared to patients after amputation. No significant differences were observed in the DASH score between the two groups. Conclusion Comparable functional results and sensory recovery but significantly less pain at rest and under strain can be expected after digit replantation when compared to digit amputation. Level of evidence IV.

Abstract
BACKGROUND Thousands of Americans sustain injuries from various household appliances each year, though injury patterns have not been well characterized. We thus sought to determine the incidence, characteristics, and trends of household appliance-related hand injuries over the past decade. METHODS The National Electronic Injury Surveillance System database (NEISS) was queried from 2010 through 2019. Our analysis grouped patients into 10-year age groups. We defined types of appliances and injuries Chi-square tests were used to compare the most common injury mechanisms by age group. RESULTS Between 2010 and 2019, 30,336 total cases of home workshop equipment-related upper extremity injuries were recorded; 2,574 (8.48%) of these affected females, compared to 27,762 (91.52%) of the cases affecting males. Across all age groups, males were between 6 and 13 more times likely to be injured than females (p < 0.001). Between 2010 and 2019, we recorded a decline in total injuries from 168,795 to 147,584, with a Pearson correlation coefficient of -0.68 (p = 0.031). The appliances most likely to injure those in their 10s through 40s were mechanical tools such as screwdrivers. Meanwhile, those in their 50s through 70s were most likely to be injured by saws. Both amputations and avulsions were found to significantly increase with age (p = 0.038, p = 0.027, respectively). Most injuries result from manual tools and saws. DISCUSSION Males are significantly more likely to incur injuries than females from maintenance equipment, and risk of avulsions and amputations increase significantly with age. This aligns with previous research which also suggested that older saws were most likely to injure older individuals; namely, following new regulations on saws, older adults were more likely to be affected. This is especially worrisome in light of recent research showing that older adults with amputations are less likely to be offered replantations. Overall, these results can continue to guide and optimize community interventions on an epidemiological basis.

Abstract
Factors associated with failure of digital revascularization and replantation procedures have been well characterized, but studies have not investigated failures occurring beyond the early postoperative period. A single-centre retrospective chart review included 284 patients (434 digits) who underwent digital revascularization or replantation. Patient-, injury- and surgery-related characteristics were compared among successful procedures, digits that failed while in hospital (early failure), and initially viable digits that failed after hospital discharge (late failure). Overall, 202 patients had successful procedures (71%). There were 51 early failures (18%) and 31 late failures (11%). Crush injuries and vein grafting were associated with early failure only. Complete amputations and leeching were strongly associated with both early and late failure. This study revealed that a substantial proportion of initially viable digits fail after discharge from hospital. Patients with signs of venous congestion may benefit from longer observation periods in hospital to avoid late failure.Level of evidence: IV.

Abstract
BACKGROUND Microsurgical anastomosis is technically difficult especially for less-experienced surgeons. Traditionally, surgeons in training could only accomplish these surgeries under intensive guiding and supervision from senior surgeons. This study presents and characterises a new method for microsurgical trainees to objectively evaluating the quality of vascular anastomosis intraoperatively. MATERIALS AND METHODS We conducted a prospective study to determine the utility of patency test of vascular anastomosis with assistance of high-speed video recording (PTHVR) to evaluate the quality of vascular anastomosis during microsurgery. To determine whether the use of PTHVR outperformed traditional supervision from senior surgeons (historical control), we compared the outcomes of microsurgeries including free flap transfer and replantation between the two groups. RESULTS A total of 211 patients were enrolled, of which 98 underwent surgery under traditional supervision and 113 underwent surgery with PTHVR. Of the 211 patients, 102 underwent digit replantation (48%), 22 underwent limb replantation (10%), and 87 underwent free flap transfer (42%). There was no statistical difference between the two groups in age, gender, BMI, pre-existing comorbidities, smoking status, alcohol consumption, and duration of surgery. Use of PTHVR as an intraoperative guide significantly decreased the rate of re-exploration surgeries (PTHVR, 8.0% [9/113]; control, 23.5% [23/98]; P = 0.002) and replantation/free flap failures (PTHVR, 8.8% [10/113]; control, 19.4% [19/98]; P = 0.029) compared with historical control under traditional supervision. CONCLUSIONS PTHVR is a useful tool for improving the success rate of microsurgery for less-experienced surgeons when compared with traditional supervision mode.

Abstract
A persistent challenge that has limited access and delivery of digit replantation surgery is timing, as ischemia time has traditionally been considered an important determinant of success. However, reports that the viability of amputated digits decreases after 6 hours of warm ischemia and 12 hours of cold ischemia are largely anecdotal. This review evaluates the quality and generalizability of available evidence regarding ischemia times after digit amputation and reported outcomes of "delayed" replantation. We identify substantial limitations in the literature supporting ischemia time cutoffs and recent evidence supporting the feasibility of delayed digit replantation. The current treatment approach for amputation injuries often necessitates transfers or overnight emergency procedures that increase costs and limit availability of digit replantation nationwide. Evidence-based changes to digit replantation protocols could lead to broader availability of this service, as well as improved care quality.

Abstract
IMPORTANCE Risk-adjusted variation in surgeon outcomes has been traditionally explained by surgeon volume and hospital infrastructure, yet it is unclear how a surgeon's operative proficiency directly contributes to their patients' outcomes. OBJECTIVE To assess the variation of surgeons' operative proficiency and investigate its association with surgical outcomes. DESIGN, SETTING, AND PARTICIPANTS This case series was a retrospective analysis of all digit replantations and revascularizations at a single US university medical center between January 2000 and August 2020. Surgeons were assigned a proficiency score based on the expected procedure difficulty and outcomes from a sample of their cases. Surgeon proficiency scores were then used to determine associations with outcomes from subsequent cases. The expected difficulty of each case was calculated using a novel scoring system that applied pooled relative risks from a meta-analysis of risk factors for replantation and revascularization failure. EXPOSURES Digit replantation and revascularization. MAIN OUTCOMES AND MEASURES Digit survival at 1-month follow up (case success) and number of complications. RESULTS A total of 145 patients and 226 digits were treated by 11 surgeons with training in hand or microsurgery (mean [SD] age, 41.9 [15.2] years; 204 [90%] men); there were 116 replantations and 110 revascularizations. Surgeon proficiency scores ranged from 1.3 to 5.7, with a mean (SD) of 3.4 (1.4). Case success rates among surgeons varied from 20.0% to 90.5%, with a mean (SD) of 64.9%. Higher proficiency scores were associated with fewer case failures: each point increase was associated with 40% decreased odds of failure (odds ratio, 0.60; 95% CI, 0.38-0.94). Every 3-point increase in proficiency score was associated with 1 less complication (effect estimate, -0.29; 95% CI, -0.56 to 0.02). Surgeon proficiency score had a greater association with case failure than surgeon volume (16.7% vs 12.0%). The final model's association with case failure had an area under the receiver operating characteristics curve of 0.93. CONCLUSIONS AND RELEVANCE Operative proficiency varied widely among practicing surgeons and accounted for 17% of estimative ability for success of digit replantation and revascularization. Greater surgeon proficiency was associated with better outcomes, indicating that the value of surgical care may be optimized by improving surgeon proficiency.

Abstract
Background: Indications for replantation following traumatic digit amputations are more liberal in the pediatric population than in adults, but delineation of patient selection within pediatrics and their outcomes have yet to be elucidated. This study uses a national pediatric database to evaluate patient characteristics and injury patterns involved in replantation and their outcomes. Methods: The Healthcare Cost and Utilization Project Kid's Inpatient Database was queried for traumatic amputations of the thumb and finger from 2000 to 2012. Participants were separated into those who underwent replantation and those who underwent amputation. Patients undergoing replantation were further divided into those requiring revision amputation and/or microvascular revision. Patient age, sex, insurance, digit(s) affected, charges, length of stay, and complications were extracted for each patient. Results: Traumatic digit amputations occurred in 3090 patients, with 1950 (63.1%) undergoing revision amputation and 1140 (36.9%) undergoing replantation. Younger patients, those with thumb injuries, females, and those covered under private insurance were significantly more likely to undergo replantation. Cost, length of stay, and in-hospital complications were significantly greater in replantation patients than in those who had undergone amputation. Following replantation, 237 patients (20.8%) underwent revision amputation and 209 (18.3%) underwent vascular revision, after which 58 required revision amputation. Risk of revision following replantation involved older patients, males, and procedures done recently. Conclusions: Pediatric patients who underwent replantation were significantly younger, female, had thumb injuries, and were covered by private insurance. Our findings demonstrate that in addition to injury factors, demographics play a significant role in the decision for finger replantation and its outcomes.

Abstract
BACKGROUND RESULTS Results of replantation surgery of replantation surgery following upper extremity traumatic amputation are extensively described in the literature, with success rates varying from 57 to 100 percent. The purpose of this study was to evaluate replantation success rate at a Level I trauma center over a 17-year period and to assess definable factors contributing to these results. METHODS A retrospective review of all digit and hand replantations at a Level I trauma center was performed using CPT codes from 2001 through 2018. Descriptive analyses, Mann-Whitney test, Kruskal-Wallis test, and logistic regressions were used. Significance was defined as p ≤ 0.05. RESULTS Analysis consisted of 76 patients with 101 amputated parts (93 digits and eight hands). Fifty-six single digit amputations (30 percent success rate), 37 multidigit injuries (22 percent digit success rate), and eight hand amputations (50 percent success rate) were attempted. The overall success rate was 25 of 76 patients (33 percent) and 29 of 101 parts (29 percent). The most common mechanism of injury was laceration (n = 56), followed by crush (n = 30), and avulsion (n = 11), with repair of laceration-type injuries having the greatest success rate (36 percent). CONCLUSIONS The authors report a lower success rate of hand and digit replantation than previously described in the literature. Whole hand and thumb replantations resulted in the highest survival rate in our series. Laceration mechanism showed a higher success rate than crush or avulsion-type injuries. The authors' modest results highlight the importance of effective internal auditing of low-volume replantation centers such as their own. Quality improvement measures are proposed for higher future success in replantation surgery at the authors' institution. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
Objectives
This study aims to evaluate the clinical results and experiences in a community hospital regarding procedures for the replantation and revascularization of fingers. Patients and methods
Between June 2015 and December 2019, a total of 58 patients (51 males, 7 females; mean age: 33.4±6.3 years; range, 23 to 46 years) who were followed after total and/or subtotal amputation and replantation were retrospectively analyzed. The patients were evaluated at nine months in terms of cold intolerance, static two-point discrimination, and functional results using the range of motion (ROM) and Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire. Results
The majority of the patients presented with work-related injuries (70%), most commonly by the mechanism of guillotine (64%), and to the dominant hand (76%) and the third finger (36%) most frequently. The overall success rate of digit salvage was 72.9% (n=51). Of 19 digits with unsuccessful surgical outcomes, seven were from total and 12 were from subtotal amputations. In the long-term, cold intolerance was observed in 14 patients (24.1%) according to the cold intolerance severity scale. The mean static two-point discrimination value was 6.0±0.7 mm and the mean QuickDASH score was 22.3±5.0. The mean ROM measured at nine months after surgery in the metacarpophalangeal and interphalangeal joints of the third and fourth digits was significantly lower than that in the others (p<0.05). Conclusion
The predictors of survival of a replanted digit indicated in this study can be used as a guide and decision-making aid for any attempts for replantation.

Abstract
BACKGROUND Surgeon experience, hospital volume, and teaching hospital status may play a role in the success of digit replantation. This study aims to analyze factors that influence digit replantation success rates. STUDY DESIGN We examined patients with traumatic digit amputations, between 2000 and 2015, from the National Health Insurance Research Database (NHIRD) of Taiwan, which comprises data of more than 99% of its population. We measured the number of traumatic digit amputations and success rate of replantation. Chi-square and ANOVA tests were used for descriptive statistics. Regression models were built to analyze the association among patient, surgeon, and hospital characteristics, and replant success. RESULTS We identified 13,416 digit replantation patients using the eligibility criteria. The overall replantation failure rate was significantly higher in medium- and high-volume hospitals (low-volume: 11%, medium-volume: 17%, and high-volume: 15%, p < 0.001). Teaching hospitals had significantly higher replantation failure rates [(15.5% vs 7.6%), odds ratio (OR) 2.0; confidence interval (CI) 1.1-3.7]. Lower surgeon case volume resulted in a significantly higher failure rate in the thumb replantation (OR 0.89; CI 0.85-0.94). CONCLUSIONS Teaching hospitals had greater odds of replantation failure, owing to being high volume centers and attempting more replantations. However, the effect of residents performing the replantation during their training should be considered. Teaching units are mandatory for resident training; however, a balance should be established to provide training, but with sufficient supervision to achieve optimal replant success. A national protocol to triage digit amputation cases to high volume centers with experienced microsurgeons will help improve the replantation success rate.

The trend of treatment and conveyance system for upper extremity replantation in Japan: A nationwide population-based study from the Japan trauma data bank. J Orthop Sci 2021; 26:271-275. [PMID: 32349884 DOI: 10.1016/j.jos.2020.03.006] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2019] [Revised: 02/06/2020] [Accepted: 03/10/2020] [Indexed: 11/16/2022]
Abstract
BACKGROUND In Japan, microsurgical skill development and a system to transfer patients to an appropriate hospital for upper extremity amputation have been promoted; however, information about trends of replantation is limited. Therefore, the aim of this study was to clarify the trends in the treatment for upper extremity amputation using the Japan Trauma Data Bank (JTDB). METHODS Data derived from JTDB (2004-2015) were used to quantify trends in the volume of replantation for upper extremity amputation including finger amputation. Trauma was diagnosed based on the Abbreviated Injury Scale code; a subgroup of patients who underwent replantation was delineated. We investigated patient demographics, infection rate, and characteristics of treating facilities. RESULTS A total of 1240 patients underwent upper extremity amputation. Among these, 510 (41.1%) underwent replantation, and the rate of replantation did not change over the study period. The average age of patients who underwent or did not undergo replantation was 45.5 and 47.2 years, respectively. The proportion of the patients who were transferred to another hospital for treatment significantly decreased between 2004 (28.5%) and 2015 (16.3%) (P < 0.01). Time taken for transfer from the accident site to hospitals increased. The rate of patients who underwent replantation differed among different hospitals; however, higher-volume hospitals were more likely to perform replantation. CONCLUSION The rate of patients transferred to another hospital decreased between 2004 and 2015; however, the rate of patients who underwent replantation remained unchanged. This suggests that the number of patients who were transported directly from the accident site to an appropriate hospital has increased, whereas the indication for care in each hospital remains unchanged. Common criteria for amputations are needed to address the differing rates of replantation among hospitals.

Abstract
BACKGROUND Since 1965, the practice of digital replantation has seen great technical strides and become commonplace worldwide. However, some American authors have recently reported declining rates of replantation. We set out to characterize the patient population and describe treatment patterns from 2005 to 2016 at a large Canadian regional replantation center. METHODS A retrospective cohort of all patients undergoing digital replantation and revascularization from 2005 to 2016 was identified. Data were collected on demographics, injuries, procedures, and outcomes. Descriptive statistics were performed, followed by a comparison of two 5-year periods to evaluate temporal trends. RESULTS A total of 234 patients were treated with 146 replantation and 204 revascularization procedures. Patients were largely male, healthy, and worked as manual labourers. Overall, the failure rate of individual repairs was 28.7%. Over time, there was a trend toward more crush or avulsion and multidigit injuries, and surgeries performed after 2011 were significantly longer. There was a significant downward trend in the number of patients treated at our center each year. Additionally, there was a statistically significant decrease in the proportion of replanted to revised digits in multidigit cases. DISCUSSION Our observation of declining replantation rates is in line with recent American observations. The reason for this is not obvious but may represent a change in injury characteristics or surgeon attitudes. CONCLUSION We suspect that these changes represent a change in workplace safety and injury characteristics, but further studies are needed to assess patient and surgeon treatment decisions.

Abstract
Hand trauma has always been a common etiology treated by the hand surgeon. However, the amount of severe hand trauma in the United States has decreased as the safety of working environments have improved and the amount of heavy industry jobs has decreased. Largely because of this, the typical hand surgery trainee is now exposed relatively infrequently to pathologies such as brachial plexus injuries, replantation surgery, and upper-extremity reconstructive microsurgery. Our hand surgery colleagues in countries such as India and China have a different experience, though. This difference provides an opportunity for educational exchange through the form of well-structured international fellowships. The American Society for Surgery of the Hand International Traveling Fellowship is specifically designed to supplement the training of young US hand surgeons in brachial plexus surgery, replantation surgery, and reconstructive microsurgery by spending short but intensive periods at some of the premier institutions in China and India.

Abstract
PURPOSE Replant survival rates have reportedly declined over the past decade. Although this problem is multifactorial, 1 potential solution may include the development of a relevant teaching model. The development of an in vivo animal model that can be used for surgical training could enhance surgeon and resident experience and potentially improve outcomes. Here, we present a novel training model for digit replantation using turkey digits. METHODS Six mature male Bourbon Red turkeys were included in this study. With the animal under general anesthesia, the third digit on either the left or the right foot was randomly selected and amputated. The medial and lateral digital neurovascular bundles were dissected on both sides and the digit was replanted. Perfusion was confirmed prior to skin closure. The foot was casted prior to extubating the turkeys. Turkeys were then placed in a non-weight-bearing sling. Digit status was evaluated twice daily. RESULTS All 6 replanted digits were viable immediately after surgery and for at least 24 hours after surgery. The average digit survival was 6 days with a maximum survival of 15 days. All digits were eventually lost owing to a variety of reasons including infection and arterial thrombosis. CONCLUSIONS The turkey digit proved to be a successful short-term animal training model for digit replantation. Future studies are needed to determine optimum standard surgical procedure and postoperative care to maximize the educational benefits of this training model. CLINICAL RELEVANCE To establish an animal model that can simulate digital replantation.

Abstract
Background: The general teaching is that increased number of vein repairs in digit replantation leads to improved venous outflow, resulting in lower need for iatrogenic bleeding, lower postoperative transfusion requirements, and better survival rates. The purpose of this study was to determine whether the traditional teaching that emphasizes the repair of multiple veins per arterial anastomosis results in superior survival rates. Methods: A retrospective review of a single urban replant center's single-digit replants distal to the mid-metacarpal level in adult patients from 2007 to 2017 was performed. Data on patient demographics, mechanism and level of injury, veins repaired, iatrogenic bleeding, postoperative transfusions, and replant survival were obtained. Results: There were a total of 54 single-digit replants. The most common mechanism was lacerations (N = 38), and the most common injury level was at the proximal phalanx (N = 21). All digits were replanted with a single arterial anastomosis-44% via grafting. In all, 0 to 3 veins were repaired per digit (mean = 1.5 veins). The mean transfusion requirement was 1.7 units. The survival rate was 50%. Digits with 1 or 2 veins repaired had lower transfusion requirements (1.1-1.3 units) and higher survival rates (56%-61%) compared with those replanted with 0 or 3 veins repaired (2.9-3.5 transfused units, 25%-29% survival). There were no differences between those digits replanted with either 1 or 2 veins repaired for transfusion requirements or survival. Conclusions: More veins repaired do not necessarily improve survival or possibly venous outflow, calling into question the traditional teaching that 2 veins should be repaired for every arterial anastomosis.

Abstract
Mangling hand injuries can be difficult to manage owing to the severity and heterogeneity of the injuries. Outcomes after reconstruction of unique injuries are less well-known but provide valuable insight. We present an unusual spare parts reconstruction of a bilateral upper-extremity mangling injury treated with a heterotopic thumb-to-thumb replantation, an acute forearm fasciocutaneous free flap, and targeted muscle reinnervation. This report highlights the utility of microsurgical reconstruction with available autogenous tissue in the acute setting.

Abstract
IMPORTANCE Traumatic digit amputation is the most common type of amputation injury, but the cost-effectiveness of its treatments is unknown. OBJECTIVE To assess the cost-effectiveness of finger replantation compared with revision amputation. DESIGN, SETTING, AND PARTICIPANTS This economic evaluation was conducted using data from the Finger Replantation and Amputation Challenges in Assessing Impairment, Satisfaction, and Effectiveness (FRANCHISE), a retrospective, multicenter cohort study at 19 centers in the United States and Asia that enrolled participants from August 1, 2016, to April 12, 2018. Model variables were based on the FRANCHISE database, Centers for Medicare & Medicaid Services, and published literature. A total of 257 participants with unilateral traumatic finger amputations treated with revision amputation or replantation distal to the metacarpophalangeal joint and at least 1 year of follow-up after treatment were included in the analysis. EXPOSURES Revision amputation or replantation of traumatic finger amputations. MAIN OUTCOMES AND MEASURES Main outcome measures were quality-adjusted life-years (QALYs), total costs (in US dollars), and incremental cost-effectiveness ratios (ICERs). A willingness-to-pay threshold of $100 000 per QALY was used to assess cost-effectiveness. RESULTS Of the 257 study participants (mean [SD] age, 46.7 [15.9] years; 221 [86.0%] male), 178 underwent finger replantation and 79 underwent revision amputation. In a base case of a 46.7-year-old patient, replantation was associated with QALY gains of 0.30 (95% credible interval [CrI], -0.72 to 1.38) for single-finger (not thumb), 0.39 (95% CrI, -1.00 to 1.90) for thumb, 1.69 (95% CrI, -0.13 to 3.76) for multifinger excluding thumb, and 1.27 (95% CrI, -2.21 to 5.04) for multifinger including thumb injury patterns. Corresponding ICERs for replantation compared with revision amputation were $99 157 per QALY for single-finger (not thumb), $66 278 per QALY for thumb, $18 388 per QALY for multifinger excluding thumb, and $21 528 per QALY for multifinger including thumb injury patterns. Sensitivity analysis revealed that age at time of injury, life expectancy, postinjury utility, wages, and time off work for recovery had the strongest associations with cost-effectiveness. Probabilistic sensitivity analysis revealed the following chances of replantation being cost-effective: 47% in single-finger (not thumb), 52% in thumb, 78% in multifinger excluding thumb, and 64% in multifinger including thumb injury patterns. CONCLUSIONS AND RELEVANCE With proper patient selection, replantation of all finger amputation patterns, whether single-finger or multifinger injuries, may be cost-effective compared with revision amputation. Multifinger replantations had a higher probability of being cost-effective than single-finger replantations. Cost-effectiveness may depend on injury pattern and patient factors and thus appears to be important for consideration when patients and surgeons are deciding whether to replant or amputate.

Abstract
Introduction Secondary procedures following digit and hand replants are often necessary to optimize functional outcomes. To date, the incidence and characteristics of secondary procedures have yet to be fully defined. Materials and Methods A literature search was performed using the NCBI (National Center for Biotechnology Information) database for studies evaluating secondary procedures following digit and hand replantation/revascularization. Studies were evaluated for frequency and type of secondary procedure following replantation. Descriptive statistical analysis was conducted across the pooled dataset. Results Nineteen studies representing 1,485 replants were included in our analysis. A total of 1,124 secondary procedures were performed on the 1,485 replants. Secondary procedures most commonly addressed tendons (27.1%), bone/joints (16.1%), soft tissue coverage (15.4%), nerve (5.4%), and scar contractures (4.5%). A total of 12.7% of replants resulted in re-amputation (16.7% of secondary procedures). The details of secondary procedures are further described in the article. Conclusion Secondary procedures are often necessary following hand and digit replants. Patients should be informed of the possible need for subsequent surgery, including delayed amputation, to improve hand function. These data improve our understanding of replant outcomes and can help patients better comprehend the decision to undergo replantation.

Abstract
Introduction Traumatic amputation of the upper limb has significant associated morbidities and disabilities. After successful replantation surgery, the micro-surgeons’ tasks are far from over. The replanted and revascularized segments have numerous functional restrictions and need various corrective secondary procedures. The aim of our study was to compare the functional results after secondary procedures by administering the Quick Disability of the Arm, Shoulder, and Hand (QuickDASH) questionnaire to patients who had successful upper limb replantation and revascularization. Materials and methods This prospective observational study involved 40 patients who had a partial or complete amputation of the upper limb and underwent secondary procedures to correct function after successful replantation and revascularization surgery. The patients’ functional outcomes after various secondary procedures were recorded using the QuickDASH questionnaire. Results The mean QuickDASH score for thumb injuries was 42.3 pre-surgery but improved to 29.5 after secondary procedures, which was statistically significant (CI 11.12-14.87, p<0.01). The mean difference in the QuickDASH scores for finger injuries was also statistically significant: 45.5 preoperation and 33.7 postoperation (CI 9.89-13.70, p<0.01). For wrist injuries, the mean QuickDASH score was 52.8 presurgery and was 46.3 postoperatively (CI 1.81-6.58, p=0.0023). The QuickDASH scores of the patients with arm and forearm injuries showed no statistically significant improvement, with a preoperation score of 58.3 declining to 55.2 (p=0.98). The overall replantation and revascularization scores were 49.725 and 41.175 pre and postoperation, respectively (CI 8.35-8.75, p<0.01). Conclusion The study finds that the level and mechanism of injury are important predictors of the functional outcomes of the replantation and revascularization of amputated upper-limb appendages. Most replanted and revascularized upper limbs have numerous functional limitations, and achieving good functional results requires one or more secondary procedures, whose type depends on various factors such as the injury type and mechanism. The QuickDASH results for functional outcomes before and after secondary procedures indicate that it is an easy-to-use, reliable, and effective measure of functional outcomes.

Abstract
Postoperative care of amputated digits begins before replantation. Detailed informed consent should be obtained and completion amputation discussed if revascularization is not ultimately successful. Complications and failure of the replanted digit should also be addressed. Postoperative pharmacologic treatment should consist of aspirin, at minimum. Complications, such as venous congestion or occlusion, and arterial thrombosis, should be dealt with expediently. Digital motion rehabilitation should start after 5 to 7 days of digital viability and splinting of the affected digit. Early protective motion protocol is implemented to maintain digital motion with emphasis on tendon glide and joint motion.

Abstract
Replantation of a digit or hand is most successful when performed at a specialized, high-volume center. However, most patients with amputations initially present to local hospitals. Therefore, patients amenable to replantation frequently require expedited transfer to a tertiary center. To maximize success of digit replants, health care providers from both the referring and the referral hospital must be facile and expeditious at transferring the injured patient. The critical aspects of triage include assessment of the injury, patient communication, interfacility communication, preparation of the amputated part and patient, and a timely transfer.

Abstract
BACKGROUND This study aimed to evaluate a novel surgical method for the acute reconstruction of defects in the thumb and other fingers by transplanting a free vascularized joint flap from the second toe and to determine its clinical curative effects. MATERIALS AND METHODS A free vascularized joint flap from the second toe was transplanted to reconstruct a complete defect of the thumb and other fingers accompanied by the loss of the proximal finger in 10 patients. Of these patients, three had their thumbs reconstructed with a free vascularized joint flap from the second toe and with the proximal interphalangeal joint flap, one had a thumb reconstructed with a free vascularized joint flap from the second toe, and six had their finger defects reconstructed with the proximal interphalangeal joint flap. The toes of the metatarsophalangeal joint were amputated at the foot donor site. All patients underwent one-stage emergency surgery. RESULTS The composite tissue flaps, replanted thumbs, and fingers survived well in all 10 cases. Follow-up visits were conducted for 6-28 months, with an average of 9 months of follow-up. The transplanted bone joints healed over a period of 6-16 weeks. Bone nonunions and refractures did not occur, and the walking function of the foot donor site was not visibly affected. CONCLUSION A free vascularized joint flap from the second toe can be transplanted to repair defects in the thumb and other fingers. This technique can be applied to recover the appearance and function of fingers.

Abstract
BACKGROUND The aim of this study was to evaluate the impact of increasing age on rates of digital failure. METHOD A retrospective cohort study of digital replantation or revascularization patients was undertaken from 2005 to 2016. Data collected consisted of patient demographics, smoking status, injury mechanisms, procedure types, and postoperative morbidity and mortality. Descriptive statistics and logistic regression were performed to assess outcomes. All comparisons were made between patients older than and younger than 60 years. RESULTS Two hundred eighty-three patients underwent replantation or revascularization; 11 percent were older than 60 years. The majority of patients had multiple devascularized digits (70 percent), most commonly inflicted by a blade mechanism (77 percent). Approximately half of the patients underwent revascularization alone (54.4 percent). American Society of Anesthesiologists score and number of comorbidities were significantly greater in the older adult group. Overall, 88 patients (31 percent) experienced digital replantation or revascularization failure, with 12 failures in patients aged 60 years or older. Multivariate logistic regression demonstrated that age did not have an impact on failure rate. Older patients did not experience more major complications, but had significantly higher rates of minor complications (p = 0.0485). CONCLUSIONS Older patients presented with significantly higher American Society of Anesthesiologists physical status and number of comorbidities, but did not experience higher rates of digital failure, major perioperative complications, or 30-day mortality. Adults aged 60 years or older should be offered digital replantation or revascularization if medically or surgically indicated. CLINICAL QUESTION/LEVEL OF EVIDENCE Risk, II.

Abstract
BACKGROUND The success of salvage procedures for failing digital replants (FR) is poorly documented. We sought to evaluate the success of salvage procedures for FR and factors contributing to successes and failures of replants. METHODS Adult patients who presented to our center between January 1, 2000 and December 31, 2015, suffered ≥1 digital amputation(s), and underwent digital replantation were included. Preoperative, perioperative, and postoperative details were recorded. Digits were monitored postoperatively via nursing and physician assessments. The presumed reason for failure, details, and outcomes of salvage attempts were recorded for FR. Length of hospital stay and complications were also recorded. RESULTS Fifty-two patients and 83 digits were included. Fifty-two digits (63%) were compromised (arterial ischemia in 15 digits; venous congestion in 37 digits) and 48 digits had salvage therapy. Twenty-one FR (44%) were salvaged via operative (1 of 2; 50%), nonoperative (19 of 43; 44%), and combined (1 of 3; 33%) therapies. FR patients were more likely than those with successful replants to receive a blood transfusion (52 vs. 23%; p = .009) with more transfused units (3.45 ± 3.30 vs. 0.86 ± 0.95; p = .001). Length of stay was prolonged for FR patients (9 [range: 2-22] vs. 7 [range: 3-19] days; p = .039). Ultimately, 59% (49 of 83) of replants were successful, where 25% (21 of 83) were successfully salvaged. CONCLUSION Nonoperative and operative salvage therapies improve the rate of replant survival. We suggest close postoperative monitoring of all replants and active salvage interventions for compromised replants in the postoperative period.

Incidence, Timing, and Risk Factors for Secondary Revision After Primary Revision of Traumatic Digit Amputations. J Hand Surg Am 2018; 43:1040.e1-1040.e11. [PMID: 29735290 DOI: 10.1016/j.jhsa.2018.03.028] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2017] [Revised: 02/04/2018] [Accepted: 03/19/2018] [Indexed: 02/02/2023]
Abstract
PURPOSE Primary revision amputation is the most common treatment method for traumatic digit amputations in the United States. Few studies have reported secondary revision rates after primary revision amputation. The primary aim of our study was to identify risk factors for secondary revision within 1 year of the index procedure. Secondarily, we describe the incidence and timing of complications requiring secondary revision. METHODS Our institution's emergency department (ED) database was reviewed for traumatic digit amputations over a 6-year period. Patients were reviewed for demographic characteristics, comorbidities, site of treatment (ED versus operating room), and complications requiring secondary revision. Conditional Cox Proportional Hazard regression was used to model hazard of revision within 1 year of index procedure relative to site of initial management, mechanism of injury, injury characteristics, and patient demographics. RESULTS Five hundred and thirty-seven patients with 677 digits were managed with primary revision amputation. Five hundred and eighty-six digits (86.6%) were revised in the ED, and 91 (13.4%) in the operating room. Ninety-one digits required secondary revision, including 83 within 1 year. No increased risk of secondary revision amputation within 1 year of the index procedure was observed for patients treated in the ED compared with the operating room. Relative to crush injuries, bite and sharp laceration amputations had 4.8 times and 2.6 times increased risk of secondary revision, respectively. The index finger had a 5.3-fold increased risk of revision with the thumb as the reference digit. Work-related injuries had a 1.9-fold increased risk of secondary revision compared with non-work-related injuries. CONCLUSIONS No evidence was found indicating that traumatic digit amputations primarily revised in the ED had an increased risk of secondary revision. Patients may be counseled on the risk of secondary procedures based on the mechanism of injury, injury characteristics and demographics, as well as the timing of complications. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
PURPOSE Traumatic digit amputations have an adverse impact on patients' daily living. Despite experts advocating for digit replantation, studies have shown a continued decrease in rate of replantation. We performed a national-level investigation to examine the recent trend of practice for digital replantation. METHODS We used the National Inpatient Sample database under the Healthcare Cost and Utilization Project to select adult patients with traumatic digit amputation from 2001 to 2014. We calculated the rate of attempted and rate of successful digit replantation per year, subcategorizing for digit type (thumb or finger) and for hospital type (rural, urban nonteaching, or urban teaching). We also analyzed the pattern of distribution of case volume to each hospital type per year. We used 2 multivariable logistic regression models to investigate patient demographic and hospital characteristics associated with the odds of replantation attempt and success. RESULTS Among the 14,872 adult patients with a single digit amputation from 2001 to 2014, only 1,670 (11.2%) underwent replantation. The rate of replantation attempt trended down over the years for both thumb and finger injuries at all hospital types, despite increasing proportions of cases being sent to urban teaching hospitals where they were more than twice as likely to undergo replantation. The rate of successful replantation stayed stable for the thumb at 82.9% and increased for fingers from 76.1% to 82.4% over the years. Patients were more likely to undergo replantation if they had private insurance or a higher level of income. Neither hospital case volume nor hospital type was predictive of successful replantation. CONCLUSIONS Although more single-digit amputations were treated by urban teaching hospitals with higher likelihood to replant, the downward trend in rate of attempt regardless of hospital type demonstrates that concentration of case volume is not the solution to reverse the declining trend. CLINICAL RELEVANCE Financial aspects of digit replantation need to be considered from both the patients' and the surgeons' perspectives to improve delivery of care for digit replantation.
