Abstract
Porous polyethylene has been widely used in craniofacial reconstruction due to its biomechanical properties and ease of handling. The objective of this study was to perform a systematic review of the literature to summarize outcomes utilizing high-density porous polyethylene (HDPP) implants in cranioplasty. A literature search of PubMed, Cochrane Library, and Scopus databases was conducted to identify original studies with HDPP cranioplasty from inception to March 2023. Non-English articles, commentaries, absent indications or outcomes, and nonclinical studies were excluded. Data on patient demographics, indications, defect size and location, outcomes, and patient satisfaction were extracted. Summary statistics were calculated using weighted averages based on the available reported data. A total of 1089 patients involving 1104 cranioplasty procedures with HDPP were identified. Patients' mean age was 44.0 years (range 2 to 83 y). The mean follow-up duration was 32.0 months (range 2 wk to 8 y). Two studies comprising 17 patients (1.6%) included only pediatric patients. Alloplastic cranioplasty was required after treatment of cerebrovascular diseases (50.9%), tumor excision (32.0%), trauma (11.4%), trigeminal neuralgia/epilepsy (3.4%), and others such as abscesses/cysts (1.4%). The size of the defect ranged from 3 to 340 cm2. An overall postoperative complication rate of 2.3% was identified, especially in patients who had previously undergone surgery at the same site. When data were available, contour improvement and high patient satisfaction were reported in 98.8% and 98.3% of the patients. HDPP implants exhibit favorable outcomes for reconstruction of skull defects. Higher complication rates may be anticipated in secondary cranioplasty cases.

Abstract
BACKGROUND The existing diagnostic criteria for septic wrist are nonspecific, exposing patients with noninfectious etiologies to surgical morbidity. This study aimed to identify predictors differentiating septic wrist from other etiologies. METHODS An institutional review board-approved retrospective review was conducted on patients with a presumed diagnosis of septic wrist (2003-2022). Bivariate and multiple regression analyses were performed to identify correlation between confirmed septic wrist and comorbidities (autoimmune diseases, immunosuppression, crystalline arthropathy, intravenous [IV] drug use, smoking), penetrating trauma, fever, multi-joint involvement, inflammatory markers (erythrocyte sedimentation rate [ESR]/C-reactive protein [CRP]/white blood cells [WBC]), serum uric acid level, blood cultures, imaging findings, and synovial fluid analysis. Categorical data were reported as median [interquartile range]. RESULTS Hundred and sixty-eight (58 females and 110 males) patients were included. The median length of hospitalization and follow-up were 6[7] days and 1[3] months. Eighty-nine (53%) patients had septic wrist confirmed with Gram stain/culture, 48 (29%) patients received alternative diagnoses, and 31 (18%) patients had undetermined diagnoses. Concomitant septic wrist and crystalline arthropathy were identified in 9 patients (6.6% of total patients). Out of the 48 patients who received alternative diagnoses, 12 (25%) underwent open drainage. Elevated synovial WBC count (95,409.4 ± 85,926.2) showed a trend of association with septic wrist (p = 0.08). Negative synovial crystals (p = 0.01), positive blood culture (p = 0.04), negative history of crystalline arthropathy (p = 0.08), and multi-joint involvement (p = 0.05) were identified as predictors of septic wrist with a combined sensitivity of 87.5%, specificity of 86.2%, and area under the curve 0.93. CONCLUSIONS Current diagnostic criteria for septic wrist have low specificity. Negative history of crystalline arthropathy, multi-joint involvement, absence of synovial crystals, and positive blood culture are helpful indicators for predicting septic wrist in patients presenting with a painful, erythematous, and swollen wrist.

Abstract
INTRODUCTION Above elbow transplants represent 19% of the upper extremity transplants. Previous large-animal models have been too distal or heterotopic, did not use immunosuppression and had short survival. We hypothesize that an orthotopic forelimb transplant model, under standard immunosuppression, is feasible and can be used to address questions on peri-transplant ischemia reperfusion injury, and post-transplantation vascular, immunologic, infectious, and functional outcomes. MATERIALS AND METHODS Four forelimbs were used for anatomical studies. Four mock transplants were performed to establish technique/level of muscle/tendon repairs. Four donor and four recipient female Yucatan minipigs were utilized for in-vivo transplants (endpoint 90-days). Forelimbs were amputated at the midarm and preserved through ex vivo normothermic perfusion (EVNP) utilizing an RBC-based perfusate. Hourly perfusate fluid-dynamics, gases, electrolytes were recorded. Contractility during EVNLP was graded hourly using the Medical Research Council scale. EVNP termination criteria included systolic arterial pressure ≥115 mmHg, compartment pressure ≥30 mmHg (at EVNP endpoint), oxygen saturation reduction of 20%, and weight change ≥2%. Indocyanine green (ICG) angiography was performed after revascularization. Limb rejection was evaluated clinically (rash, edema, temperature), and histologically (BANFF classification) collecting per cause and protocol biopsies (POD 1, 7, 30, 60 and endpoint). Systemic infections were assessed by blood culture and tissue histology. CT scan was used to confirm bone bridging at endpoint. RESULTS Animals 2, 4 reached endpoint with grade 0-I rejection. Limbs 1, 3 presented grade III rejection on days 6, 61. CsA troughs averaged 461 ± 189 ng/mL. EVNLP averaged 4.3 ± 0.52 h. Perfusate lactate, PO2 , and pH were 5.6 ± 0.9 mmol/L, 557 ± 72 mmHg and 7.5 ± 0.1, respectively. Muscle contractions were 4 [1] during EVNLP. Transplants 2, 3, 4 showed bone bridging on CT. CONCLUSION We present preliminary evidence supporting the feasibility of an orthotopic, mid-humeral forelimb allotransplantation model under standard immunosuppression regimen. Further research should validate the immunological, infectious, and functional outcomes of this model.

Abstract
BACKGROUND Ischemia and ischemia-reperfusion injury contribute to partial or complete flap necrosis. Traditionally, skin histology has been used to evaluate morphological and structural changes, however histology does not detect early changes. We hypothesize that morphological and structural skin changes in response to ischemia and IRI occur late, and modification of gene and protein expression are the earliest changes in ischemia and IRI. METHODS A systematic review was performed in accordance with PRISMA guidelines. Studies reporting skin histology or gene/protein expression changes following ischemia with or without reperfusion injury published between 2002 and 2022 were included. The primary outcomes were descriptive and semi-quantitative histological structural changes, leukocyte infiltration, edema, vessel density; secondary outcomes were quantitative gene and protein expression intensity (PCR and western blot). Model type, experimental intervention, ischemia method and duration, reperfusion duration, biopsy location and time point were collected. RESULTS One hundred and one articles were included. Hematoxylin and eosin (H&E) showed inflammatory infiltration in early responses (12-24 h), with structural modifications (3-14 days) and neovascularization (5-14 days) as delayed responses. Immunohistochemistry (IHC) identified angiogenesis (CD31, CD34), apoptosis (TUNEL, caspase-3, Bax/Bcl-2), and protein localization (NF-κB). Gene (PCR) and protein expression (western blot) detected inflammation and apoptosis; endoplasmic reticulum stress/oxidative stress and hypoxia; and neovascularization. The most common markers were TNF-α, IL-6 and IL-1β (inflammation), caspase-3 (apoptosis), VEGF (neovascularization), and HIF-1α (hypoxia). CONCLUSION There is no consensus or standard for reporting skin injury during ischemia and IRI. H&E histology is most frequently performed but is primarily descriptive and lacks sensitivity for early skin injury. Immunohistochemistry and gene/protein expression reveal immediate and quantitative cellular responses to skin ischemia and IRI. Future research is needed towards a universally-accepted skin injury scoring system.

Abstract
BACKGROUND Tissue adjunct is non-palatal tissue used to manage tension at the defect site by providing additional coverage. This review aimed to compare outcomes of various adjuncts employed in primary palatoplasty. METHODS A literature search was conducted of MEDLINE, EMBASE, and Cochrane Library with keywords cleft palate, palatoplasty, surgical flaps, and allografts. Data extracted included demographics, cleft severity, primary/adjunctive techniques, outcomes, and follow-up periods. Logistic regression analyses and chi-squared tests were performed to investigate associations among variables. RESULTS A total of 1332 patients (aged 3 months-5 years) with follow-up of 1 month to 21 years were included. Cleft severity included submucous cleft (1.7%), Veau I/II (33.3%), Veau III (46.3%), and Veau IV (15.1%). Most reported techniques were Furlow (52%) and intravelar veloplasty (14.3%) for soft palate, Bardach (27.2%), and V-Y Pushback (11.1%) for hard palate. Buccal myomucosal flap (BMMF) was performed in 45.4% of cases, followed by buccal fat pad flap/graft (BFP) in 40.8% and acellular dermal matrix (ADM) in 14%. Severe clefts (Veau III/IV) were repaired more frequently with BMMF compared with ADM (p = 0.003) and BFP (p = 0.01). Oronasal fistula occurred in 3.1% of patients, and velopharyngeal insufficiency (VPI) in 4%, both associated with Veau IV (fistula: p = 0.002, VPI: p = 0.0002). No significant differences were found in fistula (p = 0.79) or VPI (p = 0.14) rates between adjuncts. In severe clefts (Veau III/IV), ADM was associated with fistula formation (p = 0.03). CONCLUSIONS Adjuncts in primary palatoplasty may mitigate unfavorable outcomes associated with severe clefts. BMMF is superior, given its inherent tissue properties, whereas BFP is effective in reducing fistula formation.

Abstract
BACKGROUND Surgical videos are reshaping the landscape for surgical education. As this form of education has rapidly grown and become a valuable resource for experienced surgeons, residents, and students, there is great variability in the presentation of what is offered. This study aimed to assess and compare the educational quality of free flap instructional videos on public and paid platforms. METHODS Free flap videos from public (YouTube) and paid (American Society of Plastic Surgeons Education Network and Plastic and Reconstructive Surgery Journal) sources were screened independently by three reviewers. Sample size was calculated to reach 80% power. The educational quality of the videos was determined using a modified version of Laparoscopic Surgery Video Educational Guidelines (0-6 low, 7-12 medium, 13-18 high). Professionally-made videos were identified per lighting, positioning, and video/imaging quality. Interrater reliability between the three reviewers was calculated. The educational quality of the videos was compared between public and paid sources using Mood's median test. Pearson's correlation coefficient was utilized to assess the correlation between video length and educational quality. RESULTS Seventy-six videos were included (40 public, 36 paid). The median video lengths for public and paid platforms were 9.43(IQR = 12.33) and 5.07(IQR = 6.4) min, respectively. There were 18 high, 16 medium, and 6 low-quality public videos, versus 13 high, 21 medium, and 2 low-quality paid videos. Four public and seven paid videos were identified as professionally made. Interrater reliability was high (α = .9). No differences in educational quality were identified between public and paid platforms. Video length was not correlated with quality (p = .15). A video library compiling public high-quality videos was created (https://www.youtube.com/playlist?list=PL-d5BBgQF75VWSkbvEq6mfYI--9579oPK). CONCLUSIONS Public and paid platforms may provide similar surgical education on free tissue transfer. Therefore, whether to subscribe to a paid video platform for supplemental free flap education should be determined on an individual basis.

Abstract
BACKGROUND The efficacy of virtual visits in converting new patients into established patients undergoing surgical treatment has not been demonstrated. The aim of this study was to evaluate patient retention and surgical conversion rate after an initial virtual plastic surgery consultation. METHODS An IRB-approved retrospective review of all new plastic surgery patients seen between May and August 2020 at a single institution was conducted. The initial encounter type, chief complaint, demographics, treatment recommendation, insurance approval rate, number and modality of pre- and postoperative visits, time to procedure, follow up, and complications were recorded. Patient retention and surgery conversion rate were calculated. Statistical analysis was performed with Chi-squared test, Fisher's exact test, and unpaired t-test. RESULTS In total, the records of 1889 new patients were reviewed (1635 in-person, 254 virtual). Virtual patients were younger (44.5 ± 19.0 versus 49.5 ± 20.7 years, p < 0.001), and nearly half resided greater than 50 miles away (42% versus 16%, p < 0.001). Virtual patients more frequently presented for cosmetic surgery (14% versus 7%, p < 0.001), lymphedema (15% versus 3%, p < 0.001), and gender dysphoria (11% versus 2%, p < 0.001). In-person patients presented more often for trauma (18% versus 5%, p < 0.001), elective hand complaints (16% versus 3%, p < 0.001), and breast reconstruction (9% versus 4%, p < 0.01). There were no differences in patient retention (p = 0.45) and procedure conversion rate (p = 0.21) between the groups. CONCLUSION Telemedicine provides an opportunity to increase the practice catchment area and is as effective as in-person first encounters for establishing care and transition to surgery.

Abstract
PURPOSE As the duration of lifetime survival after organ transplantation continues to increase, the consequences of long-term immunosuppression, such as opportunistic and rare infections, are a high-risk reality. This study examined upper extremity infections in the transplant population to determine the current clinical risk profile, management, and outcomes. METHODS An institutional database of 16,640 patients who underwent transplantation was queried for upper extremity infections from 2005 to 2017, defined as the presence of infection from the shoulder to the fingertips. The resulting data were analyzed using multivariable linear and logistic regression modeling. RESULTS A total of 230 eligible patients experienced upper extremity infections at a mean age of 54.1 ± 15.3 years, occurring, on average, 7.9 ± 8.6 years after transplantation. The most commonly transplanted organ was the kidney (51.3%), followed by the liver (20%). The most common location of infection was the forearm (31.7%), digits (27.4%), and upper arm (17%). The most common types of infection were cellulitis (69.1%), abscess (33.5%), joint sepsis (6.5%), infectious tenosynovitis (3.9%), and osteomyelitis (1.3%). Patients taking an antifungal medication, those who had a joint infection, or those who had undergone lung transplantation had an approximately 2.5-day longer stay in the hospital. For every 1-year increase in age at the time of transplantation, the time from transplantation to infection decreased by 0.21 years. Those who had undergone bone marrow transplantation or those who were taking tacrolimus were expected to have approximately 8- and 6-year decreases, respectively, in the time from transplantation to infection. CONCLUSIONS Upper extremity infections should be individually evaluated and treated because of the heterogeneity of transplant type, immunosuppression medications, the age of the patient, and infection characteristics. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic IV.

Abstract
BACKGROUND Adult traumatic brachial plexus injuries (TBPIs) are life-altering events that can have detrimental effects on a patient's quality of life. OBJECTIVE To examine how social determinants of health (SDOH) disparities influence the risk of developing new psychosocial conditions after TBPIs in previously psychiatric-naïve patients. METHODS Between January 2010 and June 2019, a retrospective analysis was performed using PearlDiver's Mariner, an all-payer claims database, to create 3 cohorts: TBPI disparity cohort: patients with TBPI and presence of at least 1 SDOH disparity before injury, TBPI without disparity cohort: patients with TBPI and the absence of any SDOH disparity, and control cohort: patients without TBPIs. RESULTS The matched population analyzed in this study consisted of 1176 patients who were equally represented in the TBPI disparity cohort (n = 392, 33.33%), TBPI without disparity cohort (n = 392, 33.33%), and control cohort (n = 392, 33.33%). A total of 301 patients developed any psychosocial condition with 4 years of their injury. Patients in the TBPI disparity cohort had significantly higher rates of developing any psychosocial condition (31.12%, P < .0005), depression (22.70%, P = .0032), anxiety (18.62%, P = .0203), drug abuse (7.91%, P = .0060), and alcohol abuse (4.85%, P = .03499) when compared with the other cohorts. Furthermore, the disparity cohort carried a significantly increased risk of developing any psychosocial condition (hazard ratio 1.42, 95% CI 1.09-1.86). The rates of suicide attempt, post-traumatic stress disorder, and divorce did not significantly differ between groups. CONCLUSION TBPI patients with SDOH disparities are at increased risk of developing new-onset psychosocial conditions, such as depression, anxiety, drug abuse, and alcohol abuse. Level of Evidence: Prognostic Level III.

Abstract
PURPOSE The latissimus dorsi-rib osteomyocutaneous free flap (LDRF) has been used for autologous reconstruction of large composite calvarial and scalp defects. In this study, we aim to present clinical and patient-reported outcomes after LDRF reconstruction. METHODS An anatomical study was conducted to evaluate the distribution of the connecting perforators between the thoraco-dorsal and intercostal system. An IRB-approved retrospective review of ten patients who underwent LDRF and one or two ribs for treatment of cranial defects was conducted. Patient-reported outcomes regarding quality of life, neurological and functional status were evaluated using validated surveys. One-way analysis of variance (ANOVA) and post hoc Tukey's tests were used for anatomical outcomes. Preoperative and postoperative scores were compared using paired t-tests. RESULTS The 10th rib (4.65± 2.01) followed by 9th rib (3.7±1.63) had the highest number of perforators. A combination of the 9 th and 11 th ribs exhibited maximal perforator number and pedicle length.All patients had stable LDRF reconstructions. Eight patients completed both pre and postoperative questionnaires; Median clinical follow-up was 48 [34-70] months. Scores trended toward improvement but did not reach statistical significance on the Karnofsky Performance Scale (p=0.22), Functional Independence Measure (FIM; Motor p=0.52, Cognitive p=0.55), Headache Disability Index (p=0.38). The minimum clinically important difference (MCID) was surpassed, demonstrating improvement of function for 71% of patients on the Barthel Index and 63% on the Selective Functional Movement Assessment test. CONCLUSION The LDRF can improve cognitive and physical functional status in complex patients with prior failed reconstructions for composite scalp and skull defects.

Abstract
BACKGROUND This study aimed to formulate reconstructive recommendations for neurosurgical patients presenting with scalp and/or skull defects based on outcomes in a large series of patients. METHODS An institutional review board-approved retrospective review of patients who underwent scalp and/or calvarial reconstruction was conducted. Complications were divided into minor and major; early, intermediate, and late. Univariate logistic regression models were conducted to identify independent predictors of complications. Mann-Whitney U tests were used to compare survival time. Kaplan-Meier curves were developed to compare exposure of titanium and bone cranioplasties. RESULTS One hundred seventy-one patients who underwent 418 procedures were included (median 1 [1-3] surgeries per patient). Average age was 55 ± 15 years; 53% of patients were male. Median follow-up was 25.5 months [13.9-55.6 months], and 57 patients (33%) were deceased. Complications occurred following 48% of procedures; most common were titanium hardware exposure (36%), nonhealing wounds (23%), and infection (9%). Titanium cranioplasties became exposed 0.47 months [0.3-4.0 months] postoperatively. Frontal defect location was an independent predictor of major complications (odds ratio, 1.59; 95% confidence interval, 1.06-2.39; P = 0.026). Mortality rate for malignant intracranial neoplasms was 68.4% (median survival, 4.3 months), 39.1% for malignancies of both scalp and skull (7.0 months), 37.5% for scalp cancers (16.0 months), and 16.7% for meningiomas (28.2 months). CONCLUSIONS Neurosurgical patients requiring scalp and/or skull reconstruction are a complex population undergoing multiple procedures with high complication rates. Given high exposure rate of titanium hardware shortly after reconstruction, titanium cranioplasty is recommended for patients with a prognosis less than 2 to 8 months.

Abstract
Temporomandibular joint (TMJ) arthritis arises from a multitude of etiologies; however, there is no consensus definitive treatment. The complication profile of artificial TMJs is well known, and outcomes are variable and are reserved for salvage attempts. This case details a patient with persistent traumatic TMJ pain, arthritis, and single-photon emission computed tomography scan of potential nonunion. The present study reports on the first novel use of an alternative composite myofascial flap to help arthritic TMJ pain. This study details the successful use of a temporalis myofascial flap and conchal bowl autologous cartilage graft in posttraumatic TMJ degeneration.

Abstract
PURPOSE There are no established criteria for discontinuing ex vivo normothermic limb perfusion (EVNLP) before irreversible damage occurs. This study evaluates weight gain as an indicator of injury during EVNLP. METHODS Sixteen Yorkshire pig forelimbs were procured and preserved using EVNLP with a hemoglobin-based oxygen carrier (HBOC-201) or static cold storage. EVNLP continued until termination criteria were met: arterial pressure ≥ 115 mm Hg, compartment pressure > 30 mm Hg, or 20% reduction of oxygen saturation. Limb weight, contractility, hemodynamics, perfusate electrolytes, metabolites and gases were recorded. Muscles were biopsied 6-h, and muscle injury scores (MIS) calculated. Forearm compartment pressures and indocyanine green (ICG) angiography were recorded at endpoint. Outcomes were compared at 2%, 5%, 10%, and 20% limb weight gain. RESULTS EVNLP lasted 20 ± 3 h. Weight gain was observed after 13 ± 5 h (2%), 15 ± 6 h (5%), 16 ± 6 h (10%), and 19 ± 4 h (20%). Weight correlated positively with MIS (ρ = 0.92, p < 0.0001), potassium (ρ = -1.00, p < 0.0001), pressure (ρ = 0.78, p < 0.0001), and negatively with contractility (ρ = -0.96, p = 0.011). At 5% weight gain, MIS (p < 0.0001), potassium (p = 0.03), and lactate (p < 0.0001) were significantly higher than baseline. Median muscle contractility was 5 [3-5] at 2% weight gain, 4 [1-5] at 5%, 3 [0-4] and 2 [0-2] at 10% and 20%, respectively. At 20% weight gain, contractility was significantly lower than baseline (p = 0.003). Percent weight gain correlated negatively with endpoint ICG hoof fluorescence (r = -0.712, p = 0.047). CONCLUSIONS Weight gain correlated with microscopic muscle injury and was the earliest evidence of limb dysfunction. Weight gain may serve as a criterion for discontinuation of EVNLP.

Abstract
EDS (Ehlers-Danlos Syndrome) is a heterogenous group of inheritable connective tissue disorders that commonly precludes patients from being elective surgical candidates. Patients with EDS are at a higher risk of increased bleeding, delayed wound healing, and temporomandibular joint pain refractory to treatment. Historically, patients with EDS and TMJ disorders are considered inappropriate surgical candidates due to a higher risk of delayed wound healing, increased risk for uncontrolled post-surgical bleeding, and unsubstantiated outcomes in regards to elective orthognathic surgery. A review of the literature demonstrates a paucity of data accounting the use of orthognathic surgery and maxillary-mandibular advancement in patients with EDS. The present study reports on the use of orthognathic double jaw surgery in a patient with a known diagnosis of hypermobile EDS, history of TMJ subluxation and pain. This case describes a 47-year-old woman with a history of hypermobile EDS who presented with Angle Class II malocclusion, Class II skeletal pattern, and clockwise rotation of the occlusal plane associated with pain at the bilateral TMJs. She underwent maxillary-mandibular advancement with counterclockwise rotation of the occlusal plane and genioplasty. The surgery was without complications, and at 22 months follow up, the patient healed uneventfully with improvement of pain and range of motion. This case report demonstrates that with diligent patient selection, orthognathic surgery in patients with EDS can be safe and effective and should not be an absolute contraindication.

Abstract
PURPOSE The combined treatment of trapeziometacarpal joint arthritis and scapholunate advanced collapse (SLAC) wrist presents unique challenges. The consequences of the loss of radial column support caused by scaphoidectomy and trapeziectomy are not well known. The purpose of this study was to evaluate the outcomes of the simultaneous and staged treatment of trapeziometacarpal joint arthritis and SLAC wrist. METHODS A retrospective review of patients who underwent surgery for both trapeziometacarpal joint arthritis and SLAC wrist was performed. The wrist and thumb range of motion; grip and pinch strength; pain; quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores; and radiographs were analyzed. RESULTS Twenty-four patients who underwent both trapeziectomy and 1 of 3 procedures for SLAC wrist (4-corner fusion [n = 10]), proximal row carpectomy [n = 9], and total wrist arthroplasty [n = 5]) in a single stage (n = 10) or in 2 stages (n = 14) were included. The median age was 63 years. The median follow-up period was 35 months. Twelve (50%) patients underwent complete scaphoidectomy, and 12 (50%) patients underwent partial scaphoidectomy. All 3 procedures resulted in an improvement in pain at rest, pain during activity, and quick Disabilities of the Arm, Shoulder and Hand scores. The final range of motion, grip and pinch strength, and complication rates were consistent with those reported in the literature for isolated procedures. CONCLUSIONS Trapeziometacarpal joint arthritis and SLAC wrist may be treated either simultaneously or in stages. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic V.

Abstract
ABSTRACT Hand transplantation for upper extremity amputation provides a unique treatment that restores form and function, which may not be achieved by traditional reconstruction and prosthetics. However, despite enhancing quality of life, hand transplantation remains controversial, because of immunological complications, transplant rejection, and medication effects. This systematic literature review sought to collect information on current experiences and outcomes of hand transplants to determine the efficacy and utility of hand transplants. The databases PubMed, Scopus, and Embase were analyzed with combinations of "hand" or "upper extremity" or "arm" and "transplant" or "allograft," with information collected on recipient characteristics, details of transplant, immunological outcomes, functional outcomes, and complications. Functional outcomes, as measured by Disabilities of Arm, Shoulder and Hand score, were compared between patient groups using Wilcoxon signed-rank test or 1-way analysis of variance test and post hoc Tukey test. Within the 108 articles that fulfilled inclusion and exclusion criteria, there were 96 patients with 148 hand transplants. There were 57 patients who experienced acute rejection and 5 patients with chronic rejection. Disabilities of the Arm, Shoulder and Hand scores significantly decreased after hand transplantation and were significantly lower for distal transplants compared with proximal transplants. There were 3 patients with concurrent face transplantation and 2 patients with simultaneous leg transplants. Sixteen patients experienced amputation of the hand transplant, and there were 5 deaths. This study found that hand transplantation provides significant restoration of function and form, especially for proximal transplants. Reduction in complications, such as rejection and amputation, can be achieved by decreasing medication cost and patient education.

Abstract
BACKGROUND Ex vivo normothermic limb perfusion (EVNLP) preserves amputated limbs under near-physiologic conditions. Perfusates containing red blood cells (RBCs) have shown to improve outcomes during ex vivo normothermic organ perfusion, when compared with acellular perfusates. To avoid limitations associated with the use of blood-based products, we evaluated the feasibility of EVNLP using a polymerized hemoglobin-based oxygen carrier-201 (HBOC-201). METHODS Twenty-four porcine forelimbs were procured from Yorkshire pigs. Six forelimbs underwent EVNLP with an HBOC-201-based perfusate, six with an RBC-based perfusate, and 12 served as static cold storage (SCS) controls. Ex vivo normothermic limb perfusion was terminated in the presence of systolic arterial pressure of 115 mm Hg or greater, fullness of compartments, or drop of tissue oxygen saturation by 20%. Limb contractility, weight change, compartment pressure, tissue oxygen saturation, oxygen uptake rates (OURs) were assessed. Perfusate fluid-dynamics, gases, electrolytes, metabolites, methemoglobin, creatine kinase, and myoglobin concentration were measured. Uniformity of skin perfusion was assessed with indocyanine green angiography and infrared thermography. RESULTS Warm ischemia time before EVNLP was 35.50 ± 8.62 minutes (HBOC-201), 30.17 ± 8.03 minutes (RBC) and 37.82 ± 10.45 (SCS) (p = 0.09). Ex vivo normothermic limb perfusion duration was 22.5 ± 1.7 hours (HBOC-201) and 28.2 ± 7.3 hours (RBC) (p = 0.04). Vascular flow (325 ± 25 mL·min-1 vs. 444.7 ± 50.6 mL·min-1; p = 0.39), OUR (2.0 ± 1.45 mL O2·min-1·g-1 vs. 1.3 ± 0.92 mL O2·min-1·g-1 of tissue; p = 0.80), lactate (14.66 ± 4.26 mmol·L-1 vs. 13.11 ± 6.68 mmol·L-1; p = 0.32), perfusate pH (7.53 ± 0.25 HBOC-201; 7.50 ± 0.23 RBC; p = 0.82), flexor (28.3 ± 22.0 vs. 27.5 ± 10.6; p = 0.99), and extensor (31.5 ± 22.9 vs. 28.8 ± 14.5; p = 0.82) compartment pressures, and weight changes (23.1 ± 3.0% vs. 13.2 ± 22.7; p = 0.07) were not significantly different between HBOC-201 and RBC groups, respectively. In HBOC-201 perfused limbs, methemoglobin levels increased, reaching 47.8 ± 12.1% at endpoint. Methemoglobin saturation did not affect OUR (ρ = -0.15, r2 = 0.022; p = 0.45). A significantly greater number of necrotic myocytes was found in the SCS group at endpoint (SCS, 127 ± 17 cells; HBOC-201, 72 ± 30 cells; RBC-based, 56 ± 40 cells; vs. p = 0.003). CONCLUSION HBOC-201- and RBC-based perfusates similarly support isolated limb physiology, metabolism, and function.

Abstract
PURPOSE Indications for surgical treatment of severe carpal tunnel syndrome (CTS) are controversial. The aim of this study was to review the outcomes reported in the literature of carpal tunnel release in patients with severe CTS. METHODS A systematic review of the outcomes of carpal tunnel release in patients with severe CTS was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Outcome measures included change in symptoms, sensation (2-point discrimination, light touch), thenar atrophy, strength (power and pinch grip), electrophysiology, median nerve morphology, and patient-reported outcome measures. Outcomes are reported by ranges of the percentage of patients/hands improved in the included studies. RESULTS Thirty-eight papers were selected, representing 2,531 patients and 2,712 hands. Demographic information on age and sex were available for a total of 1,542 patients. Mean age ranged from 49.8 to 83 years and 72% were female. All studies that assessed patient-reported outcome measures before and after surgery reported significant improvements. Complete resolution of paresthesia occurred in 55%-98% of hands across different studies. Resolution of numbness occurred in between 39% and 94% of hands. Pain completely resolved in 64%-100% and weakness in 60%-75% of hands. Two-point discrimination and light touch improved postoperatively. Power grip, key, tripod, index-thumb pulp pinch, and thumb opposition increased. Motor and sensory amplitudes, distal motor latencies, and sensory conduction velocities improved. Patient-reported outcomes indicated symptomatic improvement and reduced disability. CONCLUSIONS Symptomatic improvement following carpal tunnel release in patients with severe CTS can occur. Patients should be counseled about the unpredictability of the outcomes and factors that might affect outcomes. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
INTRODUCTION Ex vivo normothermic limb perfusion (EVNLP) provides several advantages for the preservation of limbs following amputation: the ability to maintain oxygenation and temperature of the limb close to physiological values, a perfusion solution providing all necessary nutrients at optimal concentrations, and the ability to maintain physiological pH and electrolytes. However, EVNLP cannot preserve the organ viability infinitely. We identified evidence of mitochondrial injury (swelling, elongation, and membrane disruption) after 24 hours of EVNLP of human upper extremities. The goal of this study was to identify metabolic derangements in the skeletal muscle during EVNLP. MATERIALS AND METHODS Fourteen human upper extremities were procured from organ donors after family consent. Seven limbs underwent EVNLP for an average of 41.6 ± 9.4 hours, and seven contralateral limbs were preserved at 4°C for the same amount of time. Muscle biopsies were performed at 24 hours of perfusion, both from the EVNLP and control limbs. Perturbations in the metabolic profiles of the muscle during EVNLP were determined via untargeted liquid chromatography-mass spectrometry (MS) operated in positive and negative electrospray ionization modes, over a mass range of 50 to 750 Da. The data were deconvoluted using the XCMS software and further statistically analyzed using the in-house statistical package, MetaboLyzer. Putative identification of metabolites using exact mass within ±7 ppm mass error and MS/MS spectral matching to the mzCloud spectral library were performed via Compound Discoverer v.2.1 (Thermo Scientific, Fremont, CA, USA). We further validated the identity of candidate metabolites by matching the fragmentation pattern of these metabolites to those of their reference pure chemicals. A nonparametric Mann-Whitney U-test was used to compare EVNLP and control group spectral features. Differences were considered significantly different when P-value < 0.05. RESULTS We detected over 13,000 spectral features of which 58 met the significance criteria with biologically relevant putative identifications. Furthermore we were able to confirm the identities of the ions taurine (P-value: 0.002) and tryptophan (P-value: 0.002), which were among the most significantly perturbed ions at 24 hours between the experimental and control groups. Metabolites belonging to the following pathways were the most perturbed at 24 hours: neuroactive ligand-receptor interaction (P-values: 0.031 and 0.036) and amino acid metabolism, including tyrosine and tryptophan metabolism (P-values: 0.015, 0.002, and 0.017). Taurine abundance decreased and tryptophan abundance increased at 24 hours. Other metabolites also identified at 24 hours included phenylalanine, xanthosine, and citric acid (P-values: 0.002, 0.002, and 0.0152). DISCUSSION This study showed presence of active metabolism during EVNLP and metabolic derangement toward the end of perfusion, which correlated with detection of altered mitochondrial structure, swelling, and elongation.

Abstract
INTRODUCTION Rat sciatic nerve injury (PNR) is the most utilized model in studies on peripheral nerve regeneration. However, large animal models are increasingly favored based on the assumption that nerve regeneration in rodents achieves more favorable outcomes than in humans. The purpose of this meta-analysis was to investigate which rat PNR models are more stringent and should be used before utilizing large animal experimentation. METHODS A PRISMA-guided meta-analysis of the English literature regarding functional outcomes in rat peripheral nerve injury models was conducted. Outcomes of five basic scenarios: (1) transected nerve/negative control, (2) transection with primary microsurgical repair, (3) isogenic/autologous grafts, (4) acellular-allogenic grafts, and (5) limb transplantation were compared to sciatic nerves without any intervention/positive control. Outcomes were compared using Sciatic Functional Index (SFI). Log-based projections were generated and evaluated using mean squared error (MSE), one-way-ANOVA, and Tukey-HSD post-hoc analysis. RESULTS In total, 167 articles met the inclusion criteria. The earliest manifestations of motor recovery were encountered in the transection and primary repair group (p <.0005). There was a significant difference in recovery time and degree of recovery between all surgical models (p <.0005). At 24 weeks, the SFI in hindlimb transplantation group was significantly worse than all other groups (-74.07 ± 2.74, p <.0005). Autografts smaller than 10 mm recovered sooner than autografts longer than 10 mm (p = .021) and autografts recovered faster than allografts. CONCLUSION This meta-analysis does not support the belief that neuro-regeneration is exceptional in transection models. These models remain adequate to provide translatable information and should initially be used in investigational studies.

Abstract
INTRODUCTION With increasing popularity of minimally invasive approaches to abdominoperineal resection (APR), thigh-based flaps are becoming the preferred option for reconstruction. The gluteal-thigh flap provides sufficient bulk, albeit with a high complication rate. We reevaluated the vascularization and design of the gluteal-thigh flap. The purpose of this study is to highlight the importance of the vascularization of the posterior thigh skin by the descending branch of the inferior gluteal artery (IGA) and the profunda femoris artery (PFA) perforators to design a more reliable and versatile gluteal thigh flap. This flap is indicated in selected cases in which use of vertical rectus abdominis musculocutaneous flap is not feasible. METHODS Eleven fresh cadavers were used. The course, distribution, and diameter of IGA and PFA perforators were recorded. A wide posterior gluteal-thigh propeller flap (WPGTPF) was designed including the distance between the ischiatic tuberosity and greater trochanter; and extending it to within 8 cm of the popliteal fossa to improve flap reliability. Ten patients (mean age of 58.7 ± 10.6 years) underwent APR due to anal cancer (2) and rectal cancer (8); the approach was open in 3, laparoscopic in 6, and robotic in 1. All 10 patients received unilateral flap with a width of 12 ± 3.3 cm and surface of 405.5 ± 175.9 cm2 . RESULTS The descending branch of the IGA was dominant in 72.7% of the specimens. In 22.7% of the specimens, the pedicle of the flap derived from the first or second PFA perforators. In one case, there was a double vascularization. Descending branch of the IGA was mapped at 46 ± 7.96 mm on the X-axis (horizontal line from the ischial tuberosity [IT] to the greater trochanter) and -12.1 ± 17.9 mm on the Y-axis (vertical line from the IT to the Medial Femoral condyle). Its average caliber measured 2.18 ± 0.3 mm. The first and second PFA perforators were located at 101.6 ± 17.9 mm and 104.5 ± 15.5 mm on the X-axis; 35.9 ± 27.1 mm and 89.2 ± 37.6 mm on the Y-axis. Their average diameters were 1.84 ± 0.41 mm and 1.48 ± 0.3 mm. In two cases, the flap was based on the first PFA perforator, the rest were on the descending branch of the IGA. Neither complete nor partial flap necrosis was observed. One patient developed coccyx osteomyelitis treated and resolved with bone debridement and one patient developed a seroma of the lateral thigh that was treated conservatively. Three patients underwent a debulking procedure by a combination of liposuction and resection to improve the gluteal symmetry. All ten flaps survived completely. CONCLUSIONS Harvest of a wide flap that includes the PFA perforators and implementation of the propeller design increase the survival and versatility of the flap.

Abstract
BACKGROUND Leukodepletion of whole blood-based perfusates remains a challenge in experimental models of ex vivo perfusion. This study investigated the leukoreduction efficacy of the commonly used LeukoGuard LG Arterial and BC2 Cardioplegia filters. METHODS Eleven liters of washed porcine blood was used to evaluate the filtration efficiency of LG (n = 6) and BC2 (n = 5) filters. Filter efficacy was tested by passing 1 L of washed blood through each filter. Complete blood count was performed to detect a reduction of white blood cells, red blood cells, and hemoglobin concentration. RESULTS The BC2 Cardioplegia filter showed a significant reduction in white blood cell count (13.16 ± 4.2 × 103 cells/μL pre-filtration, 0.62 ± 0.61 cells/μL post-filtration, p = 0.005), red blood cell count (9.18 ± 0.16 × 106 cells/μL pre-filtration, 9.02 ± 0.16 × 106 cells/μL post-filtration, p = 0.012) and hemoglobin concentration (15.89 ± 0.66 g/dL pre-filtration, 15.67 ± 0.83 g/dL post-filtration, p = 0.017). Platelet reduction in the LG filter group was statistically significant (13.23 ± 13.98 × 103 cells/μL pre-filtration, 7.15 ± 3.31 × 103 cells/μL post-filtration, p = 0.029), but no difference was seen in the BC2 group. There was no significant difference in white blood cell count in the LG filter group (10.12 ± 3.0 × 103 cells/μL pre-filtration, 10.32 ± 2.44 × 103 cells/μL post-filtration, p = 0.861). CONCLUSION Our results suggest that the LG filter should not be used in ex vivo perfusion circuits for the purpose of leukodepletion. The BC2 filter can be used in EVP circuits with flow rates of less than 350 mL/min. Alternatively, perfusate may be leukodepleted before perfusion.

Abstract
Ischemia and reperfusion injury remains a significant limiting factor for the successful revascularization of amputated extremities. Ex vivo normothermic perfusion is a novel approach to prolong the viability of the amputated limbs by maintaining physiologic cellular metabolism. This study aimed to evaluate the outcomes of extended ex vivo normothermic limb perfusion (EVNLP) in preserving the viability of amputated limbs for over 24 hours. A total of 10 porcine forelimbs underwent EVNLP. Limbs were perfused using an oxygenated colloid solution at 38°C containing washed RBCs. Five forelimbs (Group A) were perfused for 12 hours and the following 5 (Group B) until the vascular resistance increased. Contralateral forelimbs in each group were preserved at 4°C as a cold storage control group. Limb viability was compared between the 2 groups through assessment of muscle contractility, compartment pressure, tissue oxygen saturation, indocyanine green (ICG) angiography and thermography. EVNLP was performed for 12 hours in group A and up to 44 hours (24-44 hours) in group B. The final weight increase (-1.28 ± 8.59% vs. 7.28 ± 15.05%, P = .548) and compartment pressure (16.50 ± 8.60 vs. 24.00 ± 9.10) (P = .151) were not significantly different between the two groups. Final myoglobin and CK mean values in group A and B were: 875.0 ± 325.8 ng/mL (A) versus 1133.8 ± 537.7 ng/mL (B) (P = .056) and 53 344.0 ± 16 603.0 U/L versus 64 333.3 ± 32 481.8 U/L (P = .286). Tissue oxygen saturation was stable until the end in both groups. Infra-red thermography and ICG-angiography detected variations of peripheral limb perfusion. Our results suggest that extended normothermic preservation of amputated limbs is feasible and that the outcomes of prolonged EVNLP (>24 hours) are not significantly different from short EVNLP (12 hours).

Abstract
INTRODUCTION Ex-vivo normothermic limb perfusion (EVNLP) has been proven to preserve limb viability better than standard cold storage. Perfusates containing packed red blood cells (pRBC) improve outcomes when compared to acellular perfusates. Limitations of pRBC-based perfusion include limited availability, need for cross match, mechanical hemolysis, and activation of pro-inflammatory proteins. Hemoglobin-based oxygen carrier (HBOC)-201 (Hemopure) is a solution of polymerized bovine hemoglobin, characterized by low immunogenicity, no risk of hemolytic reaction, and enhanced convective and diffusive oxygen delivery. This is a preliminary study on the feasibility of EVNLP using HBOC-201 as an oxygen carrier. MATERIALS AND METHODS Three porcine forelimb perfusions were performed using an established EVNLP model and an HBOC-201-based perfusate. The perfusion circuit included a roller pump, oxygenator, heat exchanger, and reservoir. Electrolytes, limb temperature, weight, compartment pressure, nerve conduction, and perfusion indicated by indocyanine green angiography and infra-red thermography were monitored. Histological evaluation was performed with hematoxylin and eosin and electron microscopy. RESULTS Three limbs were perfused for 21.3 ± 2.1 hours. Muscle contractility was preserved for 10.6 ± 2.4 hours. Better preservation of the mitochondrial ultrastructure was evident at 12 hours in contrast to crystallization and destruction features in the cold-storage controls. CONCLUSIONS An HBOC-201-EVNLP produced outcomes similar to RBC-EVNLP with preservation of muscle contractility and mitochondrial structure.

Abstract
Since 1987 we have been evaluating the cost/effectiveness ratio of tumor markers using carcinoembryonic antigen (CEA) as a leading indicator. Preliminary to the evaluation of cost/effectiveness ratio we verified the fitness of CEA requests to the proper clinical problems in order to identify any bias of cost due to inadequate CEA use. 2677 CEA orders were evaluated in 1987. The percentage of inadequate requests was very high (43%). Therefore, it seemed not advisable to carry out the evaluation of cost/effectiveness ratio, while educational actions (divulgation of informative material, service of telephone consultation) were addressed to the physicians of the geographic area of laboratory users. In 1991 the adequacy of CEA requests was reevaluated. The percentage of inadequate requests on 2647 orders was 29.4%. This result, although not yet satisfactory, suggests that proper educational programs may probably improve the fitness of tumor marker requests to correct clinical problems. Additional educational actions are mandatory to futher reduce the rate of inadequate tumor marker orders.

Abstract
Granulomatosis with polyangiitis (GPA; formerly Wegener's granulomatosis) is a rare vasculitis that commonly starts in the craniofacial region. We report a case that was masked by prior facial trauma and associated with pyoderma gangrenosum (PG). Disease progression and aggressive debridements led to severe facial tissue loss. The decision to perform a face transplant was controversial because of the risk of disease relapse on the facial allograft. We reviewed renal transplant outcomes in GPA for possible relevance. A PubMed search retrieved 29 studies. Patient and graft survival, relapse, morbidity, mortality, rejection and immunosuppression were assessed. Ten-year patient survival and graft survival were 84.4% and 72.6%, respectively. GPA relapse occurred in 31.5%, and upper airway/ocular relapse occurred in 17.8% (resolved in 76.9%). Mortality was 12.3%. Acute and chronic rejection rates were 14.9% and 6.8%, respectively. Traditional posttransplant immunosuppression was effective. Our review suggests that GPA renal transplant outcomes are comparable to general renal transplant cohorts. Furthermore, transplanted GPA patients exhibit lower disease relapse secondary to lifelong immunosuppression. This supported our decision to perform a face transplant in this patient, which has been successful up to the present time (1-year posttransplantation). Untreated GPA and PG are potential causes of worse surgical outcomes in the craniofacial region.

Abstract
BACKGROUND The surgical anatomy of the midface relevant to its subperiosteal elevation and repositioning is assessed. OBJECTIVES The aim of this study is to give more details on the anatomy relevant to the midface lift. METHODS Twenty hemifacial dissections were performed. The location of the zygomatic branches of the facial nerve (ZBFN) and the terminal branches of the infraorbital nerve (ION) were dissected. The location of the masseteric and zygomatic ligaments and the elevation of midface following their release were documented. RESULTS On average, there were 3 branches of the facial nerve innervating the zygomatic major muscle and 1.8 branches entering the muscle superior to the caudal origin of the zygomaticomaxillary (ZM) suture. The most superior ZBFN was found to lie at an average of 6.2 ± 1.6 mm cranial to ZM suture and 1.4 ± 0.4 mm superficial to the bone. The most inferior branch was at a mean of 4.8 ± 3.3 mm inferior to ZM suture. On average the ION had 5.2 branches that traveled for 10.2 mm above the periosteum before they passed into a superficial plane. Division of the zygomatico-masseteric retaining ligaments allowed for elevation of the midface by 4.8 ± 1.0 mm medially and 5.5 ± .9 mm laterally. CONCLUSIONS Branches of the ZBFN and ION lie in close proximity to the subperiosteal plane in the midface. These branches are at risk for damage during release of the upper zygomatic ligaments and placement of the periosteal suspension sutures during midface elevation procedures.

Abstract
BACKGROUND The free ileocolon flap has been considered a safe method of simultaneous restoration of swallowing and voice production; however, the management of complications at the recipient site and its impact on functional outcomes are lacking in the literature. METHODS We reviewed retrospectively all consecutive patients with combined defects of the cervical esophagus and larynx reconstructed with free ileocolon flap between July 2005 and December 2009 (follow-up of ≥18 months). Patients were evaluated during the follow-up period to judge the impact of revision surgery on functional outcomes. Complications were reviewed, and the appropriate management was reported. RESULTS Swallowing function was restored in 69% of patient; functional speech function was achieved in 59%. Fourteen of the 29 patients underwent revision surgery because of complications or to improve functions at the recipient site. The mean functional improvement after revision surgery was 1.0 point on the 5-point Likert scale for speech and 1.1 point on the 7-point Likert scale for swallowing (P < .01 each). CONCLUSION Continuous research over the last 10 years has allowed us to refine the technique and to make the outcome more predictable.
