Abstract
BACKGROUND The reconstructive ladder relies mostly on defect size and depth to determine reconstructive technique, however, in actuality, many more variables ultimately inform reconstructive decision making, especially regarding extremity soft tissue sarcoma (eSTS) defects. The purpose of this study was to describe eSTS patients who will most optimally benefit from an advanced method of reconstruction (defined as a pedicled regional flap or free flap) and to create a simple risk assessment scale that can be employed in clinical practice. STUDY DESIGN A single-institution retrospective cohort study examined patients undergoing resection of soft tissue sarcoma affecting the upper or lower extremities between 2016 and 2021. We categorized patients who required a pedicled or free flap as having had advanced reconstruction, and all other techniques were considered simple reconstruction. A regression was used to create a risk scale to guide reconstructive decision-making. RESULTS The following variables were identified as independent predictors of complications and used to create our risk scale: lower extremity tumor location, preoperative radiotherapy, tumor bed excision, male sex, hypertension, and tumor volume. Intermediate and high-risk patients reconstructed using simple techniques had significantly greater overall complication rates compared to those reconstructed with advanced techniques. Major complications were significantly greater in low-risk patients reconstructed with advanced techniques. CONCLUSIONS To minimize postoperative wound complications, low-risk patients should receive simple methods of reconstruction, whereas high-risk patients should be reconstructed using advanced techniques.

Abstract
BACKGROUND Limb-sparing resections of thigh soft tissue sarcomas (STSs) can result in adverse outcomes. Identifying preoperative predictors for wound healing complications, tumor recurrence, and mortality is crucial for informed reconstructive decision-making. We hypothesized that preoperative measurements of thigh and tumor dimensions could serve as reliable indicators for postoperative complications, recurrence, and death. PATIENTS AND METHODS In this retrospective cohort study conducted from March 2016 to December 2021, we analyzed patients undergoing thigh STS excisions followed by reconstruction. Preoperative magnetic resonance imaging or computed tomography scans provided necessary thigh and tumor dimensions. Univariate and multivariate regression assessed relationships between these dimensions and postoperative outcomes, including complications, recurrence, and death. RESULTS Upon the analysis of 123 thighs, we found thigh width to be highly predictive of postoperative complications, even surpassing body mass index (BMI) and retaining significance in multivariate regression [odds ratio (OR) 1.19; 95% CI 1.03-1.39; p = 0.03]. Sarcoma-to-thigh width and thickness ratios predicted STS recurrence, with the thickness ratio retaining significance in multivariate regression (OR 1.03; 95% CI 1.001-1.05; p = 0.041). Notably, greater thigh thickness was independently protective against mortality in multivariate analysis (OR 0.80; 95% CI 0.65-0.98; p = 0.030). CONCLUSIONS Thigh width outperformed BMI in association with postoperative complications. This may create an opportunity for intervention, where weight loss can play a role during the neoadjuvant therapy period to potentially reduce complications. Sarcoma-to-thigh width and thickness ratios, particularly the latter, hold substantial predictive value in terms of STS recurrence. Moreover, thigh thickness is an independent predictor of survival.

Abstract
OBJECTIVE Examine outcomes for lateral arm autologous tissue transfer in head and neck reconstruction. STUDY DESIGN Retrospective cohort study. SETTING Tertiary cancer center. METHODS All patients who underwent traditional lateral arm, extended lateral arm, and lateral forearm flaps for head and neck reconstruction from 2012 to 2022 were assessed. Disabilities of the arm, shoulder, and hand (DASH) was measured. Factors associated with complications and enteral or mixed diet were evaluated by multivariable regression. RESULTS Among 160 patients followed for a median of 2.3 ± 2.1 years, defects were 54% oral tongue, 18% external, 9% maxilla, 8% buccal mucosa, 9% floor of mouth, and 3% pharynx. Flap types (and median pedicle lengths) were 41% traditional lateral arm (8 cm), 25% extended lateral arm (11.5 cm), and 34% lateral forearm (14 cm). All donor sites were closed primarily; 19.6% and 0% of patients had increased DASH scores 2 and 12 weeks after reconstruction. Major complications occurred in 18.1% of patients, including 6.3% reoperation, 6.9% readmission, 3.7% fistula, and 1.8% flap loss. Complications were independently associated with peripheral vascular disease (odds ratio [OR]: 5.71, 95% confidence interval [CI]: 1.5-21.6, P = .01), pharyngeal defects (OR: 11.3, 95% CI: 1.4-94.5, P = .025), and interposition vein grafts (OR: 3.78, 95% CI: 1.1-13.3, P = .037). CONCLUSION The lateral arm free flap was safe, versatile, and reliable for head and neck reconstruction with low donor-site morbidity. Complications occurred in a fifth of patients and were associated with peripheral vascular disease, pharyngeal defects, and vein grafts.

Abstract
BACKGROUND Extremity reconstruction in skeletally immature patients presents unique challenges in terms of operative technique, bone healing, and limb function. A variety of insetting techniques have been described, with no clearly superior option. The authors hypothesized that vascularized fibula flaps placed in the intramedullary space are associated with shorter union times and better functionality compared with onlay flaps. METHODS In a cohort study, the authors retrospectively reviewed the medical records of all pediatric patients who underwent fibula flap extremity reconstruction at a single center from 2001 through 2018. Comorbidities, complications, and outcomes were analyzed. Complete fibula union was based on radiographic evidence of significant cortical bridging. RESULTS Thirty-three patients (mean age, 13.6 years; range, 2 to 18 years) underwent pedicled ( n = 7) or free ( n = 26) fibula flap reconstructions in 12 upper extremities and 21 lower extremities. Median follow-up was 69.5 months (interquartile range, 16.3 to 114.6 months). Onlay and intramedullary fibula position compared with intercalary placement (median, 13.5 and 14.6 months versus 3.4 months; P = 0.002) were associated with longer time to complete bone union. Complications including allograft fracture ( P = 0.02) and hardware removal ( P = 0.018) were also associated with longer time to complete union and eventual conversion to megaprosthesis ( P = 0.02, P = 0.038). Thirty-two patients (97%) achieved full union and a functional reconstruction. CONCLUSIONS Fibula flap reconstruction is safe and effective for pediatric long-bone reconstruction. Longer fibula union times were associated with onlay and intramedullary fibula placement, allograft fracture, and hardware removal. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
Neurofibromatosis type 1 (NF1) is an inherited multisystem disorder that affects one in 2500 to one in 5000 people. Neurofibromas are the second-most common benign peripheral nerve sheath tumors arising from Schwann cells and are associated with neurofibromatosis. Chronic pain and opioid use is elevated in patients with NF1 when neurofibromas are associated with sensory nerves. Surgical excision is the primary treatment of neurofibromas when they become large, malignant, or painful, but they are associated with high rates of recurrence. Targeted muscle reinnervation and regenerative peripheral nerve interfaces are two prophylactic surgical techniques that are used to prevent neuroma-associated residual limb and phantom pain in amputees. Both techniques stimulate physiologic regeneration of the nerve via trophic stimulus from denervated muscle. This case report describes two patients with NF1 who underwent targeted muscle reinnervation and/or regenerative peripheral nerve interfaces at the time of amputation. Despite the abnormality of the peripheral nerves involved, both patients had excellent postoperative outcomes with minimal pain. This experience advocates for the use of prophylactic nerve management techniques in neurofibromatosis patients despite baseline nerve pathology.

Abstract
BACKGROUND Outcomes of targeted muscle reinnervation (TMR) and regenerative peripheral nerve interface (RPNI) in the oncologic population are limited. We sought to examine the safety and effectiveness of TMR and RPNI in controlling postamputation pain in the oncologic population. STUDY DESIGN A retrospective cohort study of consecutive patients who underwent oncologic amputation followed by immediate TMR or RPNI was conducted from November 2018 to May 2022. The primary study outcome was postamputation pain, assessed using the Numeric Pain Scale and Patient-Reported Outcomes Measurement Information System (PROMIS) for residual limb pain (RLP) and phantom limb pain (PLP). Secondary outcomes included postoperative complications, tumor recurrence, and opioid use. RESULTS Sixty-three patients were evaluated for a mean follow-up period of 11.3 months. The majority of patients (65.1%) had a history of previous limb salvage. At final follow-up, patients had an average Numeric Pain Scale score for RLP of 1.3 ± 2.2 and for PLP, 1.9 ± 2.6. The final average raw PROMIS measures were pain intensity 6.2 ± 2.9 (T-score 43.5), pain interference 14.6 ± 8.3 (T-score 55.0), and pain behavior 39.0 ± 22.1 (T-score 53.4). Patient opioid use decreased from 85.7% preoperatively to 37.7% postoperatively and morphine milligram equivalents decreased from a mean of 52.4 ± 53.0 preoperatively to 20.2 ± 38.4 postoperatively. CONCLUSIONS In the oncologic population TMR and RPNI are safe surgical techniques associated with significant reductions in RLP, PLP, and improvements in patient-reported outcomes. This study provides evidence for the routine incorporation of TMR and RPNI in the multidisciplinary care of oncologic amputees.

Abstract
BACKGROUND As patient survival with head and neck cancer has improved, treatment goals have had to evolve to focus on improving quality of life. Traditionally, patients who have undergone mandibulectomy are left with an insensate chin and lower lip secondary to resection of the inferior alveolar nerve (IAN). The purpose of this study was to critically evaluate the authors' initial experience using processed nerve allografts (PNA) for IAN reconstruction following oncologic mandibulectomy and reconstruction with free fibula osteocutaneous flaps and to assess their patients' sensory outcomes. METHODS The authors performed a retrospective review of the first 32 patients who underwent immediate IAN reconstruction with PNA at the time of oncologic mandibulectomy and mandible reconstruction with free fibula osteocutaneous flaps at The University of Texas M. D. Anderson Cancer Center over a 1-year period. Semmes-Weinstein filament sensory testing was conducted at multiple surgical follow-up appointments to evaluate the quality of sensory recovery. RESULTS Thirteen of the 32 patients underwent postoperative Semmes-Weinstein filament testing. All 13 patients demonstrated partial return of sensation. At a mean follow-up of 8.33 months, the average level of sensation was 60.93% that of the unaffected side of the lower lip. CONCLUSIONS Patients were consistently afforded improvement in lower lip sensation using PNA-based IAN grafting as an adjunct to free fibula-based mandible reconstruction. The procedure adds no additional surgical morbidity and has shown consistent positive results.

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

Abstract
Importance Treatment options for early breast cancer include breast-conserving surgery with radiation therapy (RT) or mastectomy and breast reconstruction without RT. Despite marked differences in these treatment strategies, little is known with regard to their association with long-term quality of life (QOL). Objective To evaluate the association of treatment with breast-conserving surgery with RT vs mastectomy and reconstruction without RT with long-term QOL. Design, Setting, and Participants This comparative effectiveness research study used data from the Texas Cancer Registry for women diagnosed with stage 0-II breast cancer and treated with breast-conserving surgery or mastectomy and reconstruction between 2006 and 2008. The study sample was mailed a survey between March 2017 and April 2018. Data were analyzed from August 1, 2018 to October 15, 2021. Exposures Breast-conserving surgery with RT or mastectomy and reconstruction without RT. Main Outcomes and Measures The primary outcome was satisfaction with breasts, measured with the BREAST-Q patient-reported outcome measure. Secondary outcomes included BREAST-Q physical well-being, psychosocial well-being, and sexual well-being; health utility, measured using the EuroQol Health-Related Quality of Life 5-Dimension, 3-Level questionnaire; and local therapy decisional regret. Multivariable linear regression models with weights for treatment, age, and race and ethnicity tested associations of the exposure with outcomes. Results Of 647 patients who responded to the survey (40.0%; 356 had undergone breast-conserving surgery, and 291 had undergone mastectomy and reconstruction), 551 (85.2%) confirmed treatment with breast-conserving surgery with RT (n = 315) or mastectomy and reconstruction without RT (n = 236). Among the 647 respondents, the median age was 53 years (range, 23-85 years) and the median time from diagnosis to survey was 10.3 years (range, 8.4-12.5 years). Multivariable analysis showed no significant difference between breast-conserving surgery with RT (referent) and mastectomy and reconstruction without RT in satisfaction with breasts (effect size, 2.71; 95% CI, -2.45 to 7.88; P = .30) or physical well-being (effect size, -1.80; 95% CI, -5.65 to 2.05; P = .36). In contrast, psychosocial well-being (effect size, -8.61; 95% CI, -13.26 to -3.95; P < .001) and sexual well-being (effect size, -10.68; 95% CI, -16.60 to -4.76; P < .001) were significantly worse with mastectomy and reconstruction without RT. Health utility (effect size, -0.003; 95% CI, -0.03 to 0.03; P = .83) and decisional regret (effect size, 1.32; 95% CI, -3.77 to 6.40; P = .61) did not differ by treatment group. Conclusions and Relevance The findings support equivalence of breast-conserving surgery with RT and mastectomy and reconstruction without RT with regard to breast satisfaction and physical well-being. However, breast-conserving surgery with RT was associated with clinically meaningful improvements in psychosocial and sexual well-being. These findings may help inform preference-sensitive decision-making for women with early-stage breast cancer.

Abstract
BACKGROUND Vascularized bone grafts (VBGs) are associated with improved union and fewer instrumentation complications in the mobile spine. It is not known if VBGs are similarly efficacious after sacrectomy. METHODS We conducted a retrospective chart review of all patients who underwent total sacrectomy and immediate reconstruction with VBG between 2005 and 2019. Patient and surgical characteristics in addition to union and functional outcomes were analyzed. RESULTS We identified 10 patients (6 women and 4 men) with a mean age of 42 years (range, 12-71 years). All patients received iliolumbar instrumentation as well as a free fibula flap as a VBG. There were no complications at the fibula flap donor site or specifically related to the VBG. Bony union was achieved in 7 (88%) of 8 patients with an average union time of 6.3 months (range, 2-10 months). Surgical complications occurred in 5 patients, 4 patients required reoperation for wound dehiscence, and 1 patient required conversion to a 4-rod construct and bone grafting for instrumentation loosening and partial nonunion. Instrumentation failure developed in 1 patient, but no surgical intervention was required. One patient was able to walk independently without any limitation, 5 patients required a walker, 2 were wheelchair-bound except for short (<15 ft) distances, and 2 were lost to follow-up. CONCLUSIONS The free vascularized fibula flap is a safe and effective option for supplementing spinal reconstruction after destabilizing sacrectomy.

Abstract
Breast reconstruction is an important part of the cancer treatment paradigm and the psychosocial benefits are well described in the literature. Notably, breast reconstruction restores both the functional and emotional losses patients experience due to tumor resection. Post-cancer quality of life is an important benchmark of successful treatment; therefore, breast reconstruction is an essential component that should be offered whenever possible. Over time, reconstructive techniques and outcomes have improved dramatically resulting in better patient safety and decreased operative morbidity. When counseling a patient for surgery, the provider must consider all aspects of a patient's health. Ideally, breast cancer patients should be physically, emotionally, and oncologically appropriate candidates for reconstruction. However, in concerted effort to provide opportunities for as many patients as possible, the definition of who is a good candidate for reconstruction has evolved to include higher risk patients. These patients include those with advanced age, nicotine use, obesity, and significant ptosis. With improvements in surgical procedures and perioperative care, this population may also benefit from restorative surgery. However, the exact risk of complications and necessary counseling has gone largely undefined in this population. This article examines particular "high-risk" groups that may be challenging for extirpative and reconstructive surgeons and offers current guidelines for practice.

Abstract
BACKGROUND Targeted muscle reinnervation (TMR) has been shown to decrease or prevent neuropathic pain, including phantom and residual limb pain, after extremity amputation. Currently, a paucity of data and lack of anatomical description exists regarding TMR in the setting of hemipelvectomy and/or hip disarticulations. We elaborate on the technique of TMR, illustrated through cadaveric and clinical correlates. METHODS Cadaveric dissections of multiple transpelvic exposures were performed. The major mixed motor and sensory nerve branches were identified, dissected, and tagged. Amputated peripheral nerves were transferred to identified, labeled target motor nerves via direct end-to-end nerve coaptations per traditional TMR technique. A retrospective review was completed by our multi-institutional teams to include examples of clinical correlates for TMR performed in the setting of hemipelvectomies and hip disarticulations. RESULTS A total of 12 TMR hemipelvectomy/hip disarticulation cases were performed over a 2 to 3-year period (2018-2020). Of these 12 cases, 9 were oncologic in nature, 2 were secondary to traumatic injury, and 1 was a failed limb salvage in the setting of chronic refractory osteomyelitis of the femoral shaft. CONCLUSIONS This manuscript outlines the technical considerations for TMR in the setting of hemipelvectomy and hip disarticulation with supporting clinical case correlates.

Abstract
BACKGROUND Locally advanced malignancies of the upper torso and shoulder girdle (UT-SG) necessitate extensive resection and complex reconstruction. Due to the infrequent nature of these operations, a global reconstructive algorithm has not been defined. METHODS A retrospective review of all patients who received reconstructive surgery following malignant tumor extirpation in the UT-SG from 2008 to 2018 at the University of Texas MD Anderson Cancer Center. Factors predicting the need for flap reconstruction and risk for postoperative complications were evaluated. RESULTS In total, 252 procedures met inclusion criteria. The most common pathology was sarcoma (76%) and 52% were primary tumors. The median defect area was 112 cm2 (range 4-1350 cm2 ). Reconstructive techniques included pedicled flaps (46%), local tissue rearrangement (38%), and free flaps (16%). On univariate analysis, the probability of needing a free flap increased 39% when the defect size increased by 100 cm2 . The strongest independent predictors of requiring a free flap were major vessel exposure (adjusted odds ratio [OR] = 4.92, 95% confidence interval [CI], 1.36-17.84, P = .015) and major peripheral nerve exposure (adjusted OR = 3.2, 95% CI, 1.1-9.2, P = .031). CONCLUSION Despite the aggressive nature of their malignancies, patients requiring an UT-SG resection demonstrate high survival rates and therefore demand a durable reconstruction. Exposed critical structures and defect size were predictive of free tissue transfer.

Abstract
BACKGROUND Tumor-induced osteomalacia is a rare paraneoplastic syndrome in which patients develop hypophosphatemia and osteomalacia. METHODS AND RESULTS Here, we report a unique case of a 42-year-old man who presented to our institution with a 1-year history of pain in his ribs, hips, lower back, and feet. Radiologic examination revealed a decrease in bone density and multiple insufficiency fractures. Laboratory evaluation revealed hypophosphatemia, low serum 1,25 dihydroxy vitamin D3 , and elevated fibroblast growth factor 23 (FGF23). A positron emission tomography/CT scan showed increased uptake in the right mandibular third molar region. Panoramic radiography and CT scanning showed a lytic expansile bone lesion. A mandibular bone biopsy revealed a mixed connective tissue tumor. A right segmental mandibulectomy was performed, followed by microvascular reconstruction. The resection was confirmed by normalization of serum phosphate and FGF23. CONCLUSION Successful management of this condition was achieved, with complete surgical resection of the tumor and reconstructive surgery.

Abstract
Due to the abundant and lax tissue of the abdominal wall, most ventral trunk defects are amenable to local soft tissue closure. However, when abdominal defects are accompanied by a lack of soft tissue, the surgeon faces a more complex subset of reconstructions. Three important principles guide the reconstruction of these wounds: timing of closure, careful assessment of the true extent of the wound, and the components of the defect. This article focuses on these three guiding principles and suggests the authors' preferred technique for these difficult defects.
