Androgenic steroids induce pathologic scarring in a preclinical porcine model via dysfunctional extracellular matrix deposition.

Hypertrophic scarring is a major source of morbidity. Sex hormones are not classically considered modulators of scarring. However, based on increased frequency of hypertrophic scarring in patients on testosterone, we hypothesized that androgenic steroids induce abnormal scarring and developed a preclinical porcine model to explore these effects. Mini-swine underwent castration, received no testosterone (noT) or biweekly testosterone therapy (+T), and underwent excisional wounding. To create a delayed wound healing model, a subset of wounds were re-excised at 2 weeks. Scars from postoperative day 42 (POD42) and delayed wounds (POD28) were harvested 6 weeks after initial wounding for analysis via histology, bulk RNA-seq, and mechanical testing. Histologic analysis of scars from +T animals showed increased mean fibrosis area (16 mm2noT, 28 mm2+T; p = .007) and thickness (0.246 mm2noT, 0.406 mm2+T; p < .001) compared to noT. XX+T and XY+T scars had greater tensile burst strength (p = .024 and p = .013, respectively) compared to noT swine. Color deconvolution analysis revealed greater deposition of type I and type III collagen as well as increased collagen type I:III ratio in +T scars. Dermatopathologist histology scoring showed that +T exposure was associated with worse overall scarring (p < .05). Gene ontology analysis found that testosterone exposure was associated with upregulation of cellular metabolism and immune response gene sets, while testosterone upregulated pathways related to keratinization and laminin formation on pathway analysis. In conclusion, we developed a preclinical porcine model to study the effects of the sex hormone testosterone on scarring. Testosterone induces increased scar tissue deposition and appears to increase physical strength of scars via supraphysiologic deposition of collagen and other ECM factors. The increased burst strength seen in both XX and XY animals suggests that hormone administration has a strong influence on scar mechanical properties independent of chromosomal sex. Anti-androgen topical therapies may be a promising future area of research.

Variability in Medicaid Coverage for Gender-affirming Surgeries Across U.S. States.

OBJECTIVE: To describe the current Medicaid coverage landscape for gender-affirming surgery across the United States at the procedure level and identify factors associated with coverage. BACKGROUND: Medicaid coverage for gender-affirming surgery differs by state, despite a federal ban on gender identity-based discrimination in health insurance. States that cover gender-affirming surgery also differ in which procedures are included in Medicaid coverage, leading to confusion among patients and clinicians. METHODS: State Medicaid policies in 2021 for gender-affirming surgery were queried for each of the 50 states and the District of Columbia (D.C.). State partisanship, state-level Medicaid protections, and coverage of gender-affirming procedures in 2021 were recorded. The linear correlation between electorate partisanship and total procedures covered was assessed. Pairwise t tests were used to compare coverage based on state partisanship and the presence or absence of state-level Medicaid protections. RESULTS: Medicaid coverage for gender-affirming surgery was covered in 30 states and Washington, D.C. The most commonly covered procedures were genital surgeries and mastectomy (n = 31), followed by breast augmentation (n = 21), facial feminization (n = 12), and voice modification surgery (n = 4). More procedures were covered in Democrat-controlled or leaning states, as well as in states with explicit protections for gender-affirming care in Medicaid coverage. CONCLUSIONS: Medicaid coverage for gender-affirming surgery is patchwork across the United States and is especially poor for facial and voice surgeries. Our study provides a convenient reference for patients and surgeons detailing which gender-affirming surgical procedures are covered by Medicaid within each state.

Selective mycobacterial capture with ultraviolet-polymerized poly-dimethyldiallyl chloride functionalized surfaces.

Tuberculosis (TB) is the top cause of death from a single infectious pathogen after COVID-19. Despite molecular diagnostic advances, two-thirds of the 10 million annual TB cases are still diagnosed using direct smear microscopy which has ~50% sensitivity. To increase the analytical performance of smear microscopy, we developed and characterized a novel polymer (Polydiallyldimethylammonium chloride [PDADMAC]) engraftment on inexpensive polystyrene (PS) specifically functionalized for mycobacterial capture. Engraftment is achieved via UV photopolymerization of DADMAC monomer on plasma-activated PS. The platform was tested on sputum from presumptive TB cases in Kampala, Uganda (n = 50), with an increased overall sensitivity of 81.8% (27/33) vs. fluorescent smear microscopy 57% (19/33) compared to a molecular (Cepheid GeneXpert MTB/RIF) gold standard. Frugal smear diagnostic innovation that is rapid and does not require dedicated instrumentation may offer an important solution to bridge the TB diagnostic gap.

Early Penile and Donor Site Sensory Outcomes After Innervated Radial Forearm Free Flap Phalloplasty: A Pilot Prospective Study.

BACKGROUND: Radial forearm free flap phalloplasty (RFFF) is a set of complex reconstructive procedures aimed at creating an aesthetic and functional penis in transgender patients. Sensory recovery in the neophallus and donor site is crucial for optimizing outcomes, but the few prior studies that exist assess neophallus sensation at limited locations and time points. The purpose of this study was to prospectively quantify sensory outcomes in the neophallus and donor site following RFFF phalloplasty. METHODS: Sensation testing occurred prospectively over February 2019-January 2021 on Stage 1 RFFF phalloplasty patients using the Pressure Specified Sensory Device (PSSD). On the neophallus, one-point discrimination (1PS) pressure threshold and lengthwise sensory recovery were measured at six circumferential locations proximally to distally. On the donor site, 1PS was measured at three locations on the donor hand. RESULTS: Nineteen patients were included (average age 34.0 years old, range 18-53 years). Among patients that received neophallus testing (n = 13), eight had at least two follow-up appointments. Six of these patients had sensation as of their most recent measurement (75.0%), with an average of 73 days to regain sensation. There was a significantly greater proportion of patients with sensation at the right ventral (80.0% after 3 months vs. 11.1%-60.0% before 3 months, p = 0.024) and right lateral (100.0% after 3 months vs. 11.1%-60.0% before 3 months, p = 0.004) aspects of the neophallus over time. Pressure required to elicit sensation decreased by 18.0% from 1 week-1 month postoperatively to 3-7.7 months postoperatively in the right ventral neophallus (96.2 g/mm2 ± 11.3 g/mm2 to 56.6 ± 39.9 g/mm2, p = 0.037). Among patients that received donor site testing (n = 11), mixed effects regression analysis with random intercepts demonstrated significant changes in the thumb (3.4 g/mm2 ± 1.4 g/mm2, p < 0.05) and webspace (13.5 g/mm2 ± 4.9 g/mm2, p < 0.01) that returned to baseline at 3 months postoperatively (1.7 g/mm2 ± 1.0 g/mm2, p > 0.05, and 2.3 g/mm2 ± 4.0 g/mm2, p > 0.05, respectively). CONCLUSION: This pilot study demonstrates that quantitative sensory testing can be used to monitor post-phalloplasty sensory changes. Recovery was significantly associated with contralateral (i.e, right side in a left forearm RFF) aspects of the neophallus, suggesting a possible pattern of circumferential sensory innervation via RFFF sensory nerves. Future studies with a larger sample size and longer follow-ups are necessary to fully characterize sensory recovery in phalloplasty patients.

Temporary Declines and Demand Resurgence: Gender-Affirming Surgery Volume and Complication Trends During and After the COVID-19 Pandemic.

BACKGROUND: The COVID-19 pandemic prompted surgical volume reductions due to lockdown measures. This study evaluates COVID-19's impact on gender-affirming surgery (GAS) volume and complications from the pandemic onset through the recovery period. METHODS: The 2019-2021 National Surgical Quality Improvement Program databases were queried for transgender or gender-diverse patients using ICD-10 codes. Five time periods were analyzed: Pre-pandemic, Immediate pre-pandemic and COVID-19 outbreak, Initial COVID-19 peak, Pre-COVID-19 vaccine, and Post-vaccine release. Complications included reoperation, urinary tract infections, and wound complications. Multivariate logistic regressions assessed factors associated with undergoing surgery during the initial COVID-19 peak and experiencing surgical complications. RESULTS: Out of 2,963,230 patients, 4637 underwent GAS between 2019 and 2021. Chest feminizing and masculinizing procedures comprised 60.1% of all GAS. During the initial COVID-19 peak, all GAS surgeries nearly halved, with breast augmentations dropping to 15.3% of pre-pandemic volumes. White patients constituted a significantly higher proportion of GAS patients during the initial COVID-19 peak than in 2019 (74.7% vs. 61.0%, p = 0.014). Post-vaccine, GAS levels surged, exceeding pre-pandemic volumes by 45.5% and initial peak levels by 188.5%. The overall complication rate was 4.9%, and was significantly associated with older age, increased operative time, feminizing and masculinizing genital surgeries, and hysterectomies. The initial COVID-19 peak showed no significant correlations with surgical complications. CONCLUSIONS: GAS volume temporarily decreased during the initial COVID-19 outbreak and has since rebounded and surpassed pre-pandemic levels, corresponding with past-decade trends. Complication risks remained consistent despite the pandemic, though the results highlight potentially significant race-based disparities in GAS access during COVID-19. IMPORTANT POINTS: During the COVID-19 pandemic, public health measures led to severe volume reductions in gender-affirming surgical (GAS) procedures. Since the initial COVID-19 peak, GAS volumes have fully recovered and surpassed pre-pandemic volumes. Surgical complication rates for various GAS procedures were within expected ranges, emphasizing the overall safety of these surgeries. The study's results highlight racial disparities in undergoing GAS during the COVID-19 pandemic, with White patients disproportionately represented among those who had surgery during the COVID-19 lockdown.

Assessing and Addressing the Risk of Venous Thromboembolism Across the Spectrum of Gender Affirming Care: A Review.

OBJECTIVE: Accumulating evidence demonstrates that gender affirming hormone therapy (GAHT) improves mental health outcomes in transgender persons. Data specific to the risks associated with GAHT for transgender persons continue to emerge, allowing for improvements in understanding, predicting, and mitigating adverse outcomes while informing discussion about desired effects. Of particular concern is the risk of venous thromboembolism (VTE) in the context of both longitudinal GAHT and the perioperative setting. Combining what is known about the risk of VTE in cisgender individuals on hormone therapy (HT) with the evidence for transgender persons receiving HT allows for an informed approach to assess underlying risk and improve care in the transgender community. OBSERVATIONS: Hormone formulation, dosing, route, and duration of therapy can impact thromboembolic risk, with transdermal estrogen formulations having the lowest risk. There are no existing risk scores for VTE that consider HT as a possible risk factor. Risk assessment for recurrent VTE and bleeding tendencies using current scores may be helpful when assessing individual risk. Gender affirming surgeries present unique perioperative concerns, and certain procedures include a high likelihood that patients will be on exogenous estrogens at the time of surgery, potentially increasing thromboembolic risk. CONCLUSIONS AND RELEVANCE: Withholding GAHT due to potential adverse events may cause negative impacts for individual patients. Providers should be knowledgeable about the management of HT in transgender individuals of all ages, as well as in the perioperative setting, to avoid periods in which transgender individuals are off GAHT. Treatment decisions for both anticoagulation and HT should be individualized and tailored to patients' overall goals and desired outcomes, given that the physical and mental health benefits of gender affirming care may outweigh the risk of VTE.

Reduction in Extraocular Muscle Cross-sectional Area and Correlation With Extraocular Motility and Diplopia Following Teprotumumab for Thyroid Eye Disease.

PURPOSE: To quantify changes in extraocular muscle (EOM) cross-sectional areas (CSA) on orbital imaging in patients with thyroid eye disease before and after teprotumumab treatment, and assess for correlation with clinical outcomes. METHODS: This retrospective study included thyroid eye disease patients treated with teprotumumab who had pre- and post-treatment CT imaging. Reformatted oblique coronal images were created for each orbit in a plane perpendicular to the optic nerve. EOM CSA measurements were performed by 2 radiographic reviewers and averaged. Primary outcomes included change in ratio of total EOM to orbit CSA, and of each individual muscle group to orbit CSA, before and after treatment. Secondary outcomes included subanalysis based on age (≥40, <40 years) and Clinical Activity Score (CAS) (≥4, <4), and comparison with clinical outcomes including CAS, Hertel exophthalmometry, Gorman diplopia score, and extraocular motility. RESULTS: Forty-eight orbits of 24 patients (16 female, mean age 57.9 years) were included. There was a significant reduction in the total EOM to orbit CSA ratio ( p < 0.01) and for each individual rectus muscle to orbit CSA ratio ( p < 0.01 for all groups). Total EOM to orbit CSA ratios were reduced for 21 patients (87.5%); this was statistically significant in 13 patients (54.2%). There was significant improvement in CAS, proptosis, diplopia, and EOM motility ( p < 0.01 for all categories). There was a significant correlation between reduction of EOM CSA, and reduction of diplopia ( p < 0.01) and EOM motility ( p < 0.01). CONCLUSIONS: EOM CSA is significantly reduced following treatment with teprotumumab, and correlates with clinical findings including improvement in extraocular motility and diplopia.

Gender Affirming Surgery: A Comprehensive, Systematic Review of All Peer-reviewed Literature and Methods of Assessing Patient-centered Outcomes (Part 2: Genital Reconstruction).

OBJECTIVE: To perform the first systematic review of all available GAS publications across all procedures to assess outcomes reported in the literature and the methods used for outcome assessment. SUMMARY OF BACKGROUND DATA: Assessment of GAS results is complex and multidimensional, involving not only complication rates but also anatomic (eg, vaginal depth), functional (eg, urinary), and psychosocial outcomes. A fully comprehensive aggregation of all prior research would offer an essential cornerstone for continued progress. METHODS: A systematic review was performed after PRISMA guidelines to identify all outcomes measures in GAS cohorts, including patient-centered outcomes, complications, and functional outcomes. Data were aggregated to assess pooled rates of complications, satisfaction, and other outcomes. RESULTS: Overall, 15,186 references were identified, 4162 papers advanced to abstract review, and 1826 underwent full-text review. After review, there were 406 GAS cohort publications, including 171 vaginoplasty, 82 phalloplasty, 16 metoidioplasty, 23 oophorectomy/vaginectomy, and 21 with multiple procedures.Although 68.7% of genitoplasty papers addressed patient-centered outcomes, only 1.0% used metrics validated in the transgender population. Forty-three different outcome instruments were used. No instrument was used in more than 15% of published series and 38 were used in only 1 or 2 publications. CONCLUSIONS: Our review found high patient satisfaction for genital procedures but little concordance between study methods, with almost 90% of patient-focused outcome metrics appearing only once or twice. Standardization of outcome instruments and measurement methods through patient-inclusive, multidisciplinary consensus efforts is the essential next step for quality improvement. As GAS continues to mature, building on current foundations with the goal of improving both surgical and patient-reported outcomes is essential.

Gender Affirming Surgery: A Comprehensive, Systematic Review of All Peer-reviewed Literature and Methods of Assessing Patient-centered Outcomes (Part 1: Breast/Chest, Face, and Voice).

OBJECTIVE: To perform the first systematic review of all available gender-affirming surgery (GAS) publications across all procedures to assess both outcomes reported in the literature and the methods used for outcome assessment. SUMMARY OF BACKGROUND DATA: Rapidly increasing clinical volumes of gender-affirming surgeries have stimulated a growing need for high-quality clinical research. Although some procedures have been performed for decades, each individual procedure has limited data, necessitating synthesis of the entire literature to understand current knowledge and guide future research. METHODS: A systematic review was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify all outcomes measures in GAS cohorts, including PCOs, complications, and functional outcomes. Outcome data were pooled to assess currently reported complication, satisfaction, and other outcome rates. RESULTS: Overall, 15,186 references were identified, 4162 papers advanced to abstract review, and 1826 underwent full-text review. After review, there were 406 GAS cohort publications. Of non-genitoplasty titles, 35 were mastectomy, 6 mammoplasty, 21 facial feminization, and 31 voice/cartilage. Although 59.1% of non-genitoplasty papers addressed PCOs in some form, only 4.3% used instruments partially-validated in transgender patients. Overall, data were reported heterogeneously and were biased towards high-volume centers. CONCLUSIONS: This study represents the most comprehensive review of GAS literature. By aggregating all previously utilized measurement instruments, this study offers a foundation for discussions about current methodologic limitations and what dimensions must be included in assessing surgical success. We have assembled a comprehensive list of outcome instruments; this offers an ideal starting basis for emerging discussions between patients and providers about deficiencies which new, better instruments and metrics must address. The lack of consistent use of the same outcome measures and validated GAS-specific instruments represent the 2 primary barriers to high-quality research where improvement efforts should be focused.

Upper-Extremity Venous Thromboembolism Following Operative Treatment of Distal Radius Fractures: An Uncommon but Dangerous Complication.

PURPOSE: Distal radius fractures are the most common long bone fracture in the United States, with an estimated incidence of 640,000 cases per year. Operative fixation presents a theoretical risk factor for the development of upper-extremity venous thromboembolism (UE-VTE). Additionally, patients presenting with distal radius fracture commonly have preexisting comorbidities that further increase the risk of UE-VTE. Finally, UE-VTE is considered the highest risk for eventual development of pulmonary embolism. Despite this, scant attention has been paid to studying UE-VTE in this population. The purpose of this study was to measure the incidence of this complication and to identify possible medical factors that increased the risk of developing UE-VTE. METHODS: We queried the Truven MarketScan Commercial Claims and Encounters Database for all patients who experienced a distal radius fracture and were subsequently treated with open reduction and internal fixation between 2012 and 2016. Patients were identified using relevant Common Procedural Terminology codes. Demographic and medical variables were tabulated. Our primary outcome was the development of ipsilateral UE-VTE or pulmonary embolism in the first 60 days after surgery. RESULTS: The study included 24,494 patients. The mean age was 50.7 years (range, 18-91), and 58% were women. There were 79 cases (0.3%) of UE-VTE and 19 cases of pulmonary embolism in the study population (24.1% of all UE-VTE cases; 0.08% of total sample). Multivariable logistic regression showed that coexisting heart failure and estrogen use were associated with increased risk of UE-VTE. CONCLUSIONS: Although uncommon, the development of UE-VTE after open reduction and internal fixation for distal radius fractures is a concerning complication. Coexisting heart failure and estrogen use are associated with increased risk of UE-VTE. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Sensate total clitoris reconstruction via microneurovascular dorsal foot web space flap with pudendal nerve coaptation.

Revision surgery after gender-affirming genitoplasty is becoming more and more common as more patients gain access to surgical treatment. The complexity of genitoplasty and extensive dissection of delicate tissues predisposes patients to necrosis of the flap(s) employed, which can leave patients with complications ranging from poor aesthetics to total lack of genital sensation. The purpose of this report is to detail the revision surgery of a 32-year-old transgender woman who underwent vaginoplasty at an outside institution and presented to our clinic for clitoral reconstruction following necrosis and near-total loss of the neoclitoris. Physical exam showed extensive necrosis, and 3-Tesla magnetic resonance (MRI) revealed significant scarring of the pudendal nerve branches at the level of the pubic symphysis. Healthy nerve was identified at the level of the right inferior pubic ramus, and total clitoral reconstruction with an innervated first dorsal web space free flap anastamosed to the deep inferior epigastric vessels was performed. Complications included donor site cellulitis with partial loss of the skin graft and formation of hypertrophic scar tissue. This was treated 6 months postoperatively with excision of scar tissue in the webspace and placement of an additional full-thickness skin graft. At follow-up, the patient reported tactile and erogenous sensation of the neoclitoris itself and subjective satisfaction with the aesthetic outcome. Our results provide evidence that this flap is a feasible option to create an aesthetic and sensate neoclitoris in the setting of previous neoclitoral necrosis. This case report also describes the novel use of 3-Tesla MRI in target selection for nerve coaptation.

Prevalence of Musculoskeletal Symptoms and Ergonomics Among Plastic Surgery Residents: Results of a National Survey and Analysis of Contributing Factors.

BACKGROUND: Musculoskeletal symptoms and injuries among surgeons are underestimated but are increasingly recognized to constitute a major problem. However, it has not been established when symptoms start and what factors contribute to the development of symptoms. METHODS: A 19-question survey approved by our institution's review board, and American Council of Academic Plastic Surgery was sent to all plastic surgery residents enrolled in Accreditation Council for Graduate Medical Education-accredited plastic surgery training programs in the United States. The presence of various musculoskeletal symptoms was calculated, and predictors of these symptoms were evaluated. RESULTS: We received 104 total responses. Ninety-four percent of residents had experienced musculoskeletal pain in the operating room. The neck was the most commonly affected area (54%) followed by the back (32%) and extremities (12%). Interestingly, 52% of responders developed these symptoms during the first 2 years of their residency. Furthermore, increasing postgraduate year level (P = 0.3) and independent versus integrated status (P = 0.6) had no correlation with pain, suggesting that symptoms began early in training.Pain symptoms were frequent for 47%, whereas 5% reported experiencing symptoms during every case. The use of a headlight correlated with frequent pain (odds ratio, 2.5; P = 0.027). The use of microscope and loupes did not correlate with frequent pain. Eighty-nine percent of responders were aware of having bad surgical posture, but only 22% had received some form of ergonomics training at their institution. Sixty-four percent of responders believe that the operating room culture does not allow them to report the onset of symptoms and ask for adjustments. This was more common among residents reporting frequent pain (odds ratio, 3.12; P = 0.009). CONCLUSIONS: Plastic surgeons are at high risk for occupational symptoms and injuries. Surprisingly, symptoms start early during residency. Because residents are aware of the problem and looking for solutions, this suggests an opportunity for educational intervention to improve the health and career longevity of the next generation of surgeons.

Gender Surgery Beyond Chest and Genitals: Current Insurance Landscape.

BACKGROUND: Plastic surgery plays an essential role in the treatment of gender dysphoria. International standards of care currently consider genital and chest surgeries to be medically necessary. Ancillary procedures such as facial surgery, chondrolaryngoplasty, hair restoration/removal, and body contouring are considered cosmetic surgeries except in individual circumstances. OBJECTIVE: The authors sought to assess the frequency of coverage provision for ancillary transition-related surgeries through a cross-sectional analysis of US insurance policies. METHODS: The authors selected insurance companies based on state enrollment data and market share. Policies were identified through web-based search and telephone interviews. A list of eligible procedures was compiled and grouped into 5 categories: body masculinization, body feminization, facial procedures, hair restoration/removal, and chondrolaryngoplasty. Medical necessity criteria from publicly accessible policies were then abstracted. RESULTS: Sixty-one insurance companies held an established policy. One-third of these policies offered favorable coverage for at least 1 ancillary procedure. Chondrolaryngoplasty was the most covered category (26%, n = 16), whereas body masculinization was the least covered (8%, n = 5). Almost two-thirds of the companies with favorable policies listed coverage criteria. We identified 4 recurring requirements: age, hormone therapy, continuous living in a congruent gender role, and referral from a mental health professional. CONCLUSIONS: There is a low prevalence of US insurance coverage for ancillary gender surgeries and wide variability in coverage criteria. Reevaluation of ancillary transition-related procedures from cosmetic to medically necessary based on clinical judgement or establishment of defined coverage criteria may augment coverage and better address the needs of transgender patients.

Origins of Gender Affirmation Surgery: The History of the First Gender Identity Clinic in the United States at Johns Hopkins.

BACKGROUND: Gender-affirming care, including surgery, has gained more attention recently as third-party payers increasingly recognize that care to address gender dysphoria is medically necessary. As more patients are covered by insurance, they become able to access care, and transgender cultural competence is becoming recognized as a consideration for health care providers. A growing number of academic medical institutions are beginning to offer focused gender-affirming medical and surgical care. In 2017, Johns Hopkins Medicine launched its new Center for Transgender Health. In this context, history and its lessons are important to consider. We sought to evaluate the operation of the first multidisciplinary Gender Identity Clinic in the United States at the Johns Hopkins Hospital, which helped pioneer what was then called "sex reassignment surgery." METHODS: We evaluated the records of the medical archives of the Johns Hopkins University. RESULTS: We report data on the beginning, aim, process, outcomes of the clinic, and the reasons behind its closure. This work reveals the function of, and the successes and challenges faced by, this pioneering clinic based on the official records of the hospital and mail correspondence among the founders of the clinic. CONCLUSION: This is the first study that highlights the role of the Gender Identity Clinic in establishing gender affirmation surgery and reveals the reasons of its closure.

Selective Thumb Carpometacarpal Joint Denervation for Painful Arthritis: Clinical Outcomes and Cadaveric Study.

PURPOSE: To determine the innervation pattern to the thumb carpometacarpal (CMC) joint and assess the safety and efficacy of selective joint denervation for the treatment of pain and impairment associated with thumb CMC arthritis. METHODS: Cadaveric dissections were performed in 10 fresh upper extremities to better define the innervation patterns to the CMC joint and guide the surgical approach for CMC joint denervation. Histologic confirmation of candidate nerves was performed with hematoxylin and eosin staining. Results from a series of 12 patients with symptomatic thumb CMC arthritis who underwent selective denervation were retrospectively evaluated to determine the safety and efficacy of this treatment approach. Differences in preoperative and postoperative measurements of grip and key-pinch strength as well as subjective reporting of symptoms were compared. RESULTS: Nerve branches to the thumb CMC joint were found to arise from the lateral antebrachial cutaneous nerve (10 of 10 specimens), the palmar cutaneous branch of the median nerve (7 of 10 specimens), and the radial sensory nerve (4 of 10 specimens). With an average follow-up time of 15 months, 11 of 12 patients (92%) reported complete or near-complete relief of pain. Average improvements in grip and lateral key-pinch strength were 4.1 ± 3.0 kg (18% ± 12% from baseline) and 1.7 ± 0.5 kg (37% ± 11% from baseline), respectively. One patient experienced the onset of new pain consistent with a neuroma that resolved with steroid injection. All patients were released to light activity at 1 week after surgery, and all activity restrictions were lifted by 6 weeks after surgery. CONCLUSIONS: Selective denervation of the CMC joint is an effective approach to treat pain and alleviate impairment associated with CMC arthritis. The procedure is well tolerated, with faster recovery as compared with trapeziectomy. Branches arising from the lateral antebrachial cutaneous nerve, palmar cutaneous branch of the median nerve, and radial sensory nerve can be identified and resected with a single-incision Wagner approach.

Surgical Management of the Giant Pannus: Indications, Strategies, and Outcomes.

The obesity pandemic continues to produce an inexorable increase in the number of patients requiring surgical treatment of obesity and obesity-related complications. Along with this growing number of patients, there is a concomitant increase in the complexity of management. One particular example is the treatment of patients with an exceptionally large and morbid pannus. In this report, we detail the management of seven patients suffering from a giant pannus. Medical and surgical variables were assessed. A quality of life questionnaire was administered pre- and postoperatively. All seven patients suffered some obesity-related medical morbidity and six of seven (86%) had local complications of the giant pannus. Each patient underwent giant panniculectomy [resection weight > 13. 6 kg (30 lb)]. The mean resection weight was 20.0 kg. Four of seven (57%) patients experienced postoperative complications, with two (29%) requiring re-operation and blood transfusion. Six patients were available for long-term follow-up; 100% of participants indicated an increased quality of life while five (83%) reported additional postoperative weight loss, increase in exercise frequency and walking ability, and improved ability to work. Our results indicate that giant panniculectomy is a challenging and risky procedure, but careful patient selection and intraoperative scrutiny can ameliorate these risks and afford patients a dramatically improved quality of life.
