Accurate Plane Fat Grafting in Gluteal Augmentation: An Anatomic Study.

BACKGROUND: The safety of gluteal fat grafting is a global concern in plastic surgery. OBJECTIVE: The goal of this study was to test whether fat grafting to the buttocks with Auto Stop Reach (ASR) technology prevents penetration from the subcutaneous space into the fascia and muscle layers of the buttocks. METHODS: Fat transfer simulation was performed with blue dye on 8 fresh tissue cadaver buttocks by 3 board-certified plastic surgeons (S.S.K., S.C., B.W.). An open control was utilized to visualize the process in the different anatomic layers, and all of the other procedures were performed blindly, akin to live surgery. After blue dye transfer reached maximum capacity (ranging from 400-800 mL per buttock), dissection of the anatomical layers of the buttocks was performed to determine the plane(s) of injection. RESULTS: Blue dye fat transfer injection to the buttocks did not penetrate the gluteal fascia or muscle layers from the subcutaneous space while using ASR. CONCLUSIONS: Auto Stop Reach technology supports the safety of gluteal fat transfer in the subcutaneous space by board-certified plastic surgeons.

Does Size Really Matter? A Review on How to Determine the Optimal Umbilical Size During an Abdominoplasty.

Background: The umbilicus has historical significance regarding health and beauty principles. The visually pleasing aesthetic of the umbilicus has become a vital standard for the perceived success of an abdominoplasty procedure. While the ideal position and shape of the umbilicus have been studied extensively in literature, less is known about the optimal size. Herein, the authors provide a comprehensive literature review to help determine the ideal umbilical size. Methods: A computerized search in the PubMed database was performed to identify articles that discussed ideal umbilical size. Results: The review was performed in July 2022. A total of 21 articles were initially identified, only 6 of which discussed umbilical size. References from the included articles were also evaluated for relevance and resulted in 10 additional articles in the final review. Most of the articles indicated that a smaller umbilicus was found to be aesthetically pleasing, but a numerical range of values were not specified. Conclusions: Although the literature on the ideal umbilical size is sparse, the consensus is toward a smaller, vertically oriented umbilicus.

The Double Donut: A Safe and Simple Option for Immediate Nipple Areolar Complex Reconstruction in Skin-Sparing Mastectomy Patients With Contraindications to Nipple-Sparing Mastectomy.

Background: Restoration of the nipple areolar complex (NAC) has been shown to improve quality of life (QoL) in post-mastectomy patients. Despite expansion of nipplesparing mastectomy inclusion criteria, many patients remain ineligible and are relegated to bilateral skin-sparing mastectomy. In this study, we evaluated immediate NAC reconstruction with the double donut areolar graft and split nipple composite graft reconstruction (DDSNS). Methods: A single-center prospective study was performed for patients undergoing immediate post-mastectomy reconstruction with the DDSNS technique. Demographics and post-reconstruction endpoints were collected, focusing on aesthetic and functional outcomes. Results: A total of 31 patients and 62 breasts underwent immediate reconstruction with the DDSNS technique. Four of 62 (6.4%) nipple composite grafts and 1 of 62 (1.6%) areolar grafts experienced partial graft loss. All incidents of initial loss healed to a satisfactory result. All patients were able to proceed with adjuvant therapy, if indicated, without delay. Conclusions: The DDSNS technique can be successfully applied to achieve cosmetically satisfactory results in the post-mastectomy patient. This technique has shown reliable outcomes with respect to graft success and patient satisfaction with their NAC reconstruction.

Obesity and the Latissimus Dorsi Flap: A Radiologic Study.

Introduction: The increasing prevalence of obesity in patients with breast cancer has prompted a reappraisal of the role of the latissimus dorsi flap (LDF) in breast reconstruction. Although the reliability of this flap in obese patients is well-documented, it is unclear whether sufficient volume can be achieved through a purely autologous reconstruction (eg, extended harvest of the subfascial fat layer). Additionally, the traditional combined autologous and prosthetic approach (LDF + expander/implant) is subject to increased implant-related complication rates related to flap thickness in obese patients. The purpose of this study is to provide data on the thicknesses of the various components of the latissimus flap and discuss the implications for breast reconstruction in patients with increasing body mass index (BMI). Methods: Measurements of back thickness in the usual donor site area of an LDF were obtained in 518 patients undergoing prone computed tomography-guided lung biopsies. Thicknesses of the soft tissue overall and of individual layers (e.g., muscle, subfascial fat) were obtained. Patient, demographics including age, gender, and BMI were obtained. Results: A range of BMI from 15.7 to 65.7 was observed. In females, total back thickness (skin, fat, muscle) ranged from 0.6 to 9.4 cm. Every 1-point increase in BMI resulted in an increase of flap thickness by 1.11 mm (adjusted R2 of 0.682, P < .001) and an increase in the thickness of the subfascial fat layer by 0.513 mm (adjusted R2 of 0.553, P < .001). Mean total thicknesses for each weight category were 1.0, 1.7, 2.4, 3.0, 3.6, and 4.5 cm in underweight, normal weight, overweight, and class I, II, III obese individuals, respectively. The average contribution of the subfascial fat layer to flap thickness was 8.2 mm (32%) overall and 3.4 mm (21%), 6.7 mm (29%), 9.0 mm (30%), 11.1 mm (32%), and 15.6 mm (35%) in normal weight, overweight, class I, II, III obese individuals, respectively. Conclusion: The above findings demonstrate that the thickness of the LDF overall and of the subfascial layer closely correlated with BMI. The contribution of the subfascial layer to overall flap thickness tends to increase as a percentage of overall flap thickness with increasing BMI, which is favourable for extended LDF harvests. Because this layer cannot be separated from overall thickness on examination, these results are useful in estimating the amount of additional volume obtained from an extended latissimus harvest technique.

Introduction: La prévalence croissante d'obésité chez les patientes atteintes du cancer du sein a suscité une réévaluation du rôle du lambeau du grand dorsal (LGD) en reconstruction mammaire. La fiabilité de ce lambeau est bien établie en cas d'obésité, mais on ne sait pas si le volume suffit pour effectuer une reconstruction purement autologue (p. ex., prélèvement élargi de la couche adipeuse sous-aponévrotique). De plus, en cas d'obésité, la combinaison habituelle de l'approche autologue et prothétique (LGD+expanseur et implant) est liée à un taux de complications plus élevé lié aux implants à cause de l'épaisseur du lambeau. La présente étude visait à obtenir des données sur l'épaisseur des diverses parties du grand dorsal et à traiter des conséquences de la reconstruction mammaire chez les patientes ayant un IMC plus élevé. Méthodologie: Les chercheurs ont mesuré l'épaisseur du dos au siège habituel de prélèvement du LGD chez 518 patientes dans le cadre d'une biopsie pulmonaire orientée par tomodensitométrie en position couchée. Ils ont mesuré l'épaisseur globale du dos et l'épaisseur de chaque couche dans cette région. Ils ont également obtenu les données démographiques des patientes, y compris l'âge, le genre et l'IMC. Résultats: Les chercheurs ont observé une fourchette d'IMC de 15,7 à 65,7. Chez les femmes, l'épaisseur totale du dos (peau, adiposité, muscle) variait entre 0,6 et 9,4 cm. Chaque point ajouté à l'IMC est associé à une augmentation de l'épaisseur du lambeau de 1,11 mm (rapport de cote rajusté [RCR] de 0,682, p<0,001) et à une augmentation de l'épaisseur de la couche adipeuse sous-aponévrotique de 0,513 mm (RCR de 0,553, p<0,001). L'épaisseur totale moyenne pour chaque catégorie de poids correspondait à 1,0, 1,7, 2,4, 3,0, 3,6 et 4, cm chez les patientes en insuffisance pondérale, de poids normal, en surpoids et obèses de classe I, II et III, respectivement. L'apport moyen de la couche adipeuse sous-aponévrotique à l'épaisseur du lambeau était de 8,2 mm (32 %) globalement et de 3,4 mm (21 %), 6,7 mm (29 %), 9,0 mm (30 %), 11,1 (32 %) et 15,6 mm (35 %) chez les patientes de poids normal, en surpoids et obèses de classe I, II, III, respectivement. Conclusion: Les résultats précédents démontrent que l'épaisseur globale du LGD et de la couche sous-aponévrotique est étroitement liée à l'IMC. L'apport de la couche sous-aponévrotique a tendance à être proportionnel à l'IMC en pourcentage de l'épaisseur globale du lambeau, ce qui est favorable à un prélèvement étendu du LGD. Puisque cette couche ne peut pas être séparée de l'épaisseur globale à l'examen, ces résultats sont utiles pour évaluer le volume supplémentaire obtenu à partir de la technique de prélèvement élargi du grand droit.

The 5 D's to Dunk the Dog: A Retrospective Clinical Review to Prevent Dog-Ear Contour Abnormalities in Vertical Breast Reductions and Breast Lifts.

Background: In 2020, reduction mammoplasties and mastopexies comprised 34.2% of all breast surgeries performed by plastic surgeons. Various approaches for the skin incision of these procedures have been described. The vertical pattern has become an increasingly popular option due to its lower scar burden. However, it is prone to dog-ear formation along the caudal aspect of the incision. Herein, we describe 5 technical steps to eliminate the dog-ear in patients undergoing vertical mammoplasties. Methods: A retrospective chart review was performed on all patients who underwent vertical breast reduction and mastopexy between the years 2008 and 2020 performed by the senior author. The 5 steps employed in eliminating the dog-ear are delineated and depicted pictorially. Results: A total of 58 patients and 89 breasts were operated upon. A majority of 66.6% were Caucasian, 33.3% were African American, and 1 patient was of Hispanic descent. The mean age was 53.2 years (19-73 years), and average BMI was 31.5 kg/m2 (21.3-42.7 kg/m2). The average resection weights for reduction and mastopexy patients were 479 grams (100-1500 grams) and 58.1 grams (18-100 grams), respectively. Mean follow-up was 10.5 months (1-35 months). Only one patient developed a dog-ear (1.7%) in bilateral breasts (2.2%); however, the patient did not request a revision. Our revision rate over 13 years remained at 0%. Conclusions: Utilizing these 5 technical steps reduces the risk of dog-ear deformity and thereby diminishes the overall need for revisional surgery in patients undergoing short scar vertical mammoplasties.

Centralizing the Umbilicus in Abdominoplasty: Eccentric versus Concentric Fascial Plication in Addition to Medializing at the Skin.

BACKGROUND: The umbilicus is often not a midline structure. Centralization of the umbilicus during an abdominoplasty is routinely performed at the level of the skin; however, this is associated with a high rate of postoperative reversion. The authors propose using an eccentric fascial plication centered on the true midline to maintain postoperative centralization of the umbilicus in addition to correction at the skin level. METHODS: A retrospective study was conducted of all patients between 2015 and 2019 who underwent abdominoplasty with either skin only (concentric plication) or fascial (eccentric plication) umbilical centralization. The Fisher exact test and t test were used to compare the two groups and assess differences in rates of umbilical reversion. RESULTS: A total of 71 patients were included in the study; the majority of patients were women [ n = 69 (97%)] and White [ n = 50 (70%)]. There were 28 (39%) patients who underwent concentric plication, and 43 (61%) had eccentric plication. Mean body mass index in the concentric and eccentric groups was 32 kg/m 2 and 28.5 kg/m 2 , respectively. Average follow-up was 51.6 months for concentric plication and 27.8 months for eccentric plication. Of those who received concentric plication, 10 patients (36%) had their umbilicus revert to the preoperative position; none in the eccentric plication group reverted ( P < 0.0001). CONCLUSIONS: Midline placement of the umbilicus during an abdominoplasty is important in providing symmetry to optimize aesthetics. Eccentric fascial plication maintains the centralization of the umbilicus when compared with concentric fascial plication with skin-only centralization. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Wine, Honey, and Boiling Oil: A Modern Understanding of Ancient Wound Care Practices.

The origins of wound care date back to ancient civilizations. From boiling oil to honey to wine, healers and caregivers have adopted a fascinating array of items to cleanse, dress, and bandage wounds over the ages. While wound care practices have developed over time, the physicians and surgeons of ancient times and the Middle Ages helped build the foundation for present-day wound care. A modern scientific understanding of these treatments illustrates why practitioners abandoned some practices while others remain in use today.

Prevention of Implant Malposition in Latissimus Dorsi Myocutaneous Flap Breast Reconstruction Using an Acellular Dermal Matrix With Pectoralis Muscle Following Mastectomy for Breast Cancer: A Clinical Review.

Background: Latissimus dorsi myocutaneous (LDM) pedicled flaps are a well-established method for breast reconstruction in women with inadequate soft tissue coverage following mastectomy for breast cancer. The robust nature of the latissimus blood supply can accommodate immediate implant placement to increase breast volume; however, a known risk factor with this technique is implant malposition. By utilizing an acellular dermal matrix (ADM) in subpectoral implant-based LDM reconstruction, it is hypothesized that patients will experience a lower incidence of implant malposition. This 13-year retrospective review aims to evaluate the effectiveness of breast reconstruction using this technique. Methods: A retrospective review was conducted to identify all patients who underwent breast reconstruction following mastectomy with a LDM flap, subpectoral implant, and an ADM from 2007 to 2020 by a single surgeon at a single institution. Demographic and clinical data were collected and analyzed. Results: A total of 40 patients (LDM flaps, N = 51) were identified. Mean participant age was 50.25 ± 9.67 years and mean body mass index (BMI) was 30.85 ± 6.15 kg/m2. Comorbidities included hypertension (40.0%), diabetes mellitus (17.5%), and current smoking (25.0%). Mean follow-up was 31.52 ± 29.51 months. The most common complication was seroma formation (9.8%). No patients experienced implant malposition or flap necrosis. Conclusions: The use of a LDM flap and an ADM in implant-based breast reconstruction are each well described in the literature. This 13-year series supports the efficacy of these techniques utilized in combination to provide an aesthetic result while mitigating implant malposition during breast reconstruction of oncologic patients.

Functional Disability Associated With Proximal Clavicle Resection and Pectoralis Flap Transposition for Sternoclavicular Joint Infections.

Background: Sternoclavicular joint infections (SCJI) are increasing with the opioid crisis and increased intravenous drug abuse (IVDA). Proximal clavicle resection with subsequent pectoralis muscle transposition is part of the treatment of such infections, but the long-term effects on shoulder function are not clear. Methods: This report presents a consecutive series of 15 cases of SCJI treated with proximal clavicle resection and pectoralis muscle flap coverage. Patient-reported outcomes were recorded using the Shoulder Disability Questionnaire (SDQ) developed by van der Heijden et al. Results: The average age of patients was 50 years (range, 23-73 years), with nearly half being male (7/15). Of these patients, 3 were lost to follow-up, 1 was excluded due to subsequent shoulder surgery for an unrelated problem, and another was excluded due to subsequent medical issues that precluded a reliable history. Recurrence was noted in 1 patient with ongoing IVDA. Average length of follow-up was 12 months (range, 8-19 months). The long-term shoulder disability was minimal (mean score of 6 ± 9). Among patients with IVDA, however, the long-term shoulder disability was significantly higher (mean score of 33 ± 16, P < .05). Conclusions: In cases where the SCJI was attributed to IVDA, the long-term shoulder disability score was significantly higher, despite resolution of infection. Possible explanations include the self-reporting nature of the SDQ and the well-documented issues with chronic pain in patients with opioid dependency.  Of the patients lost to follow-up, 2 of 3 had infections attributed to IVDA, highlighting the difficulty of meaningful follow-up in this vulnerable patient population.

Restoring Breast Volume in High BMI Patients: A Single-Center Review of Breast Reconstruction Using Hyperinflated Saline Implants.

Background: Breast reconstruction in the obese patient is often fraught with poor patient satisfaction due to inadequate volume restoration. The off-label hyperinflation of saline implants is a direct yet controversial solution to this problem, with limited studies in the literature. This study sought to determine the safety and efficacy of this technique for breast reconstruction. Methods: A retrospective chart review was performed to identify all patients with a body mass index (BMI) greater than or equal to 30 kg/m2 who underwent breast reconstruction between the years 2013 to 2020 with saline implants filled beyond the manufacturer's maximum recommended volume. Results: The 21 patients identified had an average age of 49 years. The mean BMI was 39.5 kg/m2. A total of 42 implants were placed; 34 were 800 mL, 4 were 750 mL, and 4 were 700 mL. The average overfill volume was 302 mL (138%). Mean follow-up was 65.0 months. Of these, 1 (4.8%) patient with a history of chest wall radiotherapy underwent reoperation for unilateral implant exposure 27 days after the index procedure, no patient sustained spontaneous leak or rupture, and 1 patient had unilateral deflation following emergent central line and pacemaker placement 2 years after the implant was placed for an unrelated cardiovascular event. Conclusions: Hyperinflation of saline implants beyond the maximum recommended volume may be considered for volume replacement in obese patients undergoing implant-based breast reconstruction. This practice is well tolerated, has a complication rate comparable to using implants filled to the recommended volume, and has the potential to restore lost breast volume in the obese patient post mastectomy.

Posterior Interosseous Nerve Graft: Utilizing External Landmarks and Anthropometric Ratios to Predict Available Length for Digital Nerve Reconstruction in a Cadaveric Study.

Objective: In digital nerve defects that require grafting, autografts remain the efficacious option. The sensory posterior interosseous nerve (PIN) is an ideal choice as it is of similar caliber to digital nerves and leaves no donor morbidity upon resection. However, a finite length of harvestable PIN exists, and considerable variations of this length have been reported in the literature. There exists no predictive model to estimate this length. We sought to determine a method to accurately predict the available length of PIN based on individual patient anthropometry. Methods: A cadaveric dissection study was performed in a fresh tissue laboratory. The length of the sensory branch of the PIN and various anthropometric measurements were made in respect to surface anatomy of the ulna to develop a predictable ratio for available PIN donor graft. Results: A total of 16 specimens were obtained. On average the length of the PIN was 5.7 cm (range: 3.3-9. cm) and the length of the ulna was 25.7 cm (range: 23.5-30.6 cm). The ratio of PIN to ulnar length was 0.222 (r = 0.4651). Using one-fifth the length of the ulna, the mean predicted length of the PIN was 5.14 cm (range: 4.7-6.1 cm). On univariate analysis, there was no significant difference between the measured and predicted PIN length (P = .249). Conclusion: An anthropometric ratio predicated on reproducible surface anatomy of the ulna is a useful tool in predicting the sensory PIN length. Such a prediction may be a useful in guiding patient discussions concerning surgical options for digital nerve reconstruction.

Objectif: Dans les cas d'anomalies des nerfs digitaux qui exigent une greffe, les autogreffes sont les plus efficaces. Le nerf interosseux postérieur (NIP) sensitif est le choix idéal, car son calibre est semblable à celui des nerfs digitaux et qu'il ne provoque aucun problème de santé au site de résection. Cependant, la longueur du NIP pouvant être récolté est limitée, et d'énormes variations sont présentées dans les publications. Aucun modèle prédictif ne permet d'évaluer cette longueur. Les chercheurs ont entrepris d'établir une méthode pour prédire avec fiabilité la longueur disponible du NIP d'après les caractéristiques anthropométriques de chaque patient. Méthodologie: Les chercheurs ont procédé à une étude de dissection cadavérique dans un laboratoire de tissus frais. Ils ont mesuré le rameau sensitif du NIP et diverses dimensions anthropométriques d'après l'anatomie de surface de l'ulna pour établir un ratio prévisible de greffe du NIP disponible chez le donneur. Résultats: Les chercheurs ont obtenu 16 prélèvements et calculé une longueur moyenne du NIP de 5,7 cm (plage de 3,3 cm à 9,6 cm) et une longueur moyenne de l'ulna de 25,7 cm (plage de 23,5 cm à 30,6 cm). Ils ont calculé un ratio de 0,222 (r = 0,4651) entre la longueur du NIP et de l'ulna. D'après le cinquième de la longueur de l'ulna, ils ont prédit une longueur moyenne du NIP de 5,14 cm (plage de 4,7 cm à 6,1 cm). À l'analyse univariée, ils n'ont constaté aucune différence significative entre la longueur mesurée et prédite du NIP (P = 0,249). Conclusion: Le ratio anthropométrique établi d'après l'anatomie de la surface reproductive de l'ulna est un outil utile pour prédire la longueur du NIP sensitif. Une telle prédiction peut être utile pour orienter les échanges avec le patient au sujet des possibilités chirurgicales de la reconstruction du nerf digital.

Anatomic surface landmarks to guide injection for posterior interosseous nerve block.

Proper injection of the posterior interosseous nerve (PIN) is important for both the therapeutic and diagnostic management of wrist pain. However, no anatomical study exists describing the site of injection based on individual wrist width. We sought to develop a reproducible anthropometric ratio utilizing external wrist surface anatomy to predict a safe and accurate injection site for the PIN. Fresh frozen cadaver forearms were dissected at the University of Louisville tissue lab. Several anthropometric measurements were obtained in order to develop a reproducible ratio to calculate location of injection. A total of 16 cadaver forearms of equal male to female ratio were obtained. On average, the male forearm had a greater mean wrist circumference obtained at the level of Lister's tubercle compared to female forearms, 17.1 cm vs. 13.5 cm. An injection given ulnar to proximal edge of Lister's tubercle at a length of one-fourth the distance between Lister's tubercle and radial aspect of ulnar styloid resulted in 100% accurate perineural injection without intraneural injection. An anthropometric ratio of one-fourth the distance from Lister's tubercle to the ulnar styloid was able to predict accurate injection sites for the distal PIN in cadaveric specimens of varying anatomical proportions.

Surface Landmarks to Provide a Safe Ulnar Nerve Block in the Wrist: Anatomical Study and Literature Review.

Introduction: Use of local anesthesia in awake patients undergoing hand surgery has become increasingly popular. A thorough understanding of local anatomy, such as the distal wrist for ulnar nerve block, is required to provide safe blockade. We sought to conduct an anatomic study of the distal wrist and review cadaveric studies describing various techniques for ulnar nerve block. Methods: Dissection of fresh-frozen cadaver forearms at the University of Louisville Robert Acland Fresh Tissue Lab assessing relationships between the flexor carpi ulnaris tendon and the ulnar nerve and the ulnar artery was performed. Three cadaveric studies on ulnar nerve blockade using the ulnar, volar, and/or transtendinous technique were identified and reviewed. Results: A total of 16 cadaver forearms of equal male to female ratio were obtained. The ulnar nerve was noted to be directly posterior to the flexor carpi ulnaris tendon in 15 (93.8%) forearms, with 1 (6.3%) specimen having the nerve extend along the ulnar border of the flexor carpi ulnaris. The ulnar artery was radial to the ulnar nerve 1 cm proximal to the pisiform in all specimens. In all 3 cadaveric studies, only the ulnar technique was associated with no ulnar artery and/or ulnar nerve injury. Conclusion: Knowledge of distal wrist anatomy can help minimize risk of iatrogenic injury during local blockade. On review, the ulnar approach provides the safest method for ulnar nerve block.

Students teaching students: A survey of a medical student led surgical skills workshop - A prospective cohort study.

BACKGROUND: Surgical skills training is a recognized vital component of medical education, yet a standardized curriculum does not exist. Early opportunities for skills development and mentorship may increase student interest in pursuing surgery. We evaluated the effects of a student-led, faculty-supervised suture clinic on student comfort level with basic surgical skills and interest in surgery. METHODS: A cohort survey study of 103 second-year medical students participating in a surgical skills course was performed between the years 2016-2018. Upon completion of the course, we assessed their comfort level with performing six basic skills as well as their interest in pursuing surgery based on pre- and post-course surveys. RESULTS: Mean age was 25 years and 50.5% were female. Most students (61.2%) had no prior suturing experience. Upon completion of the course, there was a significant improvement (p = < 0.0001) in comfort level for each of the six skills. Most students (81%) reported an increased interest in surgery. CONCLUSIONS: Early implementation of a basic skills workshop can augment student comfort level and promote an interest in surgery. Peer student mentors can effectively lead the workshop and minimize the time commitment needed by surgical faculty. This can serve as a new direction in medical education and an avenue for further studies to analyze the longitudinal effects of the curriculum on career choice and success in surgical residency.

Breast Reconstruction With Local Flaps: Don't Forget Grandma.

Objective: Lateral breast defects of various causes can be reconstructed with random patterned local flaps utilizing oncoplastic techniques. These local flaps are used frequently in other areas but are infrequent in breast reconstruction despite affording excellent utility in small lateral defects. We sought to demonstrate this with a case series involving 5 patients who underwent oncoplastic breast surgery with random patterned flap reconstruction. Methods: From 2016 to 2017, 3 different varieties of random flaps were used in 5 women requiring lateral breast defect reconstruction secondary to resection of localized cancer or cutaneous lesion. The local flaps included a rhomboid flap, the bilobed flap, and a rotational flap. Patients were then evaluated in the clinic 10 to 12 months postoperatively for complications, symmetry, and satisfaction of reconstruction. Results: In 4 of 5 patients, the local flap remained fully viable and there was no incidence of seroma, infection, or further complications. One patient developed a post-operative hematoma requiring evacuation and a second patient experienced distal flap necrosis and delayed wound healing. Patients reported satisfaction with the reconstruction. Conclusions: Several random patterned local flaps exist for a variety of breast defects. They can yield excellent cosmetic results, high patient satisfaction, and bolster a low rate of complications. Our case series emphasizes the utility of random patterned flaps for lateral breast oncoplastic reconstruction.

Basic suture technique: Instructional videos explaining suturing for medical students in a qualitative study.

BACKGROUND: Understanding basic surgical skills is important for medical students prior to entering residency regardless of future specialty. In these videos we provide instruction for suturing as it relates to skin closure. MATERIAL AND METHODS: Instructional videos were created by the senior faculty (R.A. and M.K.) to teach medical students at the University of Louisville suturing techniques. RESULTS: Entering and exiting the needle at an angle of 90° or greater allows for tissue eversion. Inadequate eversion of tissue or inadequate angling of the needle will lead to tissue inversion. When suturing uneven edges, a deep bite on the low side and a shallow bite on the high side will allow for appropriate tissue leveling. For buried sutures, skin eversion with substantial dermal bites and proper knot location is essential. CONCLUSION: Understanding the basics of skin apposition will provide students with knowledge about primary wound healing and prepare them for residency.

Anatomic Landmarks to Locate the Median Nerve for Safe Wrist Block or Carpal Tunnel Steroid Injection.

Introduction: Carpal tunnel syndrome is the most common entrapment neuropathy involving the upper extremity. As such, various nonoperative techniques have been developed to aid in management of mild to moderate disease, including local steroid injection. However, definitive guidelines for needle/injection location have not been defined, especially in relation to diminishment of iatrogenic injury to the median nerve. Methods: A cadaveric study was designed to determine the average width of the median nerve, as well as its location specifically in relation to the palmaris longus (if present), the flexor carpi radialis, and the midpoint of the wrist. All measurements were obtained at the radial tip of the interstyloid line. Results: Data demonstrated that the average width of the median nerve was 7.85 mm and that it lies ulnar in location to the palmaris longus (3 mm), as well as the midpoint of the wrist at the radial tip of the interstyloid line (0.43 mm). Furthermore, the distance between the median nerve and the flexor carpi radialis was measured to be 9.57 mm. Outcomes: Therefore, injection location should be radial with respect to the palmaris longus and the midline of the wrist. It can be just ulnar to the flexor carpi radialis tendon or between 8 and 10 mm radial to the midpoint of the wrist in order to prevent median nerve injection and direct trauma to the nerve.
