Epidemiology of distal radius fractures: Elucidating mechanisms, comorbidities, and fracture classification using the national trauma data bank.

BACKGROUND: An update on the epidemiology of distal radius fractures in the United States is necessary, particularly as the elderly population grows. Additionally, age and frailty have been associated with complications following surgical fixation of DRFs. Herein, we utilize the National Trauma Data Bank, a robust nationwide resource, to investigate the relationship between demographics, comorbidities, injury and fracture characteristics, and admission details. METHODS: Patients with isolated distal radius fractures were identified from the National Trauma Data Bank (2016-2019) according to ICD-10 codes. Univariate and multivariate regressions were conducted to determine independent risk factors for bilateral fractures, displaced fractures, open fractures, as well as length of hospital stay and adverse discharge disposition for patients undergoing inpatient surgical fixation. RESULTS: The incidence of DRFs was 3.6/1,000 trauma-related emergency department visits and 10.8/1,000 upper extremity traumas. Trauma mechanism was significantly associated with displaced and open fractures. Age (OR 1.01, 95% CI 1.01-1.01), BMI (OR 1.02, 95% CI 1.01-1.02), smoking (OR 1.34, 95% CI 1.15-1.57), and alcohol level (trace: OR 2.18, 95% CI 1.41-3.29; intoxicated: OR 2.20, 95% CI 1.63-2.95) were significantly associated with open fractures. Machinery (ß=2.04, 95% CI 1.00-3.08) and MVT (ß=0.39, 95% CI 0.08-0.69) mechanisms were independent risk factors for longer length of stay. mFI-5 was an independent risk factor, in a stepwise fashion, for both length of stay and adverse discharge disposition. CONCLUSIONS: High-energy mechanisms and risk factors for poor skin quality were significantly associated with open fractures. mFI-5 was an independent risk factor for longer length of stay and non-routine discharges in patients of all ages, despite controlling for other comorbidities, unrelated complications, and mechanism of injury. Trauma mechanism was an independent risk factor for prolonged length of stay only, particularly in patients younger than 65 years of age.

A Systematic Review of the Impact of Patient Factors on BREAST-Q Outcomes After Reduction Mammoplasty.

BACKGROUND: As reduction mammoplasty rises in popularity, it will become increasingly important to understand the patient-reported outcome measurements associated with a successful operation. There has been a growing body of literature on BREAST-Q outcomes for patients undergoing reduction mammoplasty, but meta-analyses of patient factors and BREAST-Q Reduction Module scores are lacking. This study sought to ascertain which patient factors were associated with improvements in BREAST-Q scores compared with preoperative levels. METHODS: A literature review through August 6, 2021, was conducted using the PubMed database to select publications using the BREAST-Q questionnaire to evaluate outcomes after reduction mammoplasty. Studies examining breast reconstruction, breast augmentation, oncoplastic reduction, or breast cancer patients were excluded. BREAST-Q data were stratified by comorbidities, age, body mass index (BMI), complication rate, and resection weight. RESULTS: Among 14 articles and 1816 patients, the mean age ranged from 15.8 to 55 years, mean BMI ranged from 22.5 to 32.4 kg/m2, and bilateral mean resected weight ranged from 323 to 1845.96 g. Overall complication rate was 19.9%. On average, satisfaction with breasts improved by 52.1 ± 0.9 points (P < 0.0001), psychosocial well-being improved by 43.0 ± 1.0 points (P < 0.0001), sexual well-being improved by 38.2 ± 1.2 points (P < 0.0001), and physical well-being improved by 27.9 ± 0.8 points (P < 0.0001). The mean age was positively correlated with preoperative sexual well-being (Spearman rank correlation coefficient [SRCC]: 0.61, P < 0.05). Body mass index was negatively correlated with preoperative physical well-being (SRCC: -0.78, P < 0.01) and positively correlated with postoperative satisfaction with breasts (SRCC: 0.53, P < 0.05). The mean bilateral resected weight was significantly positively correlated with postoperative satisfaction with breasts (SRCC: 0.61, P < 0.05). No significant correlations were observed between complication rate and preoperative, postoperative, or mean change in BREAST-Q scores. CONCLUSIONS: Reduction mammoplasty improves patient satisfaction and quality of life as reflected by the BREAST-Q. Although preoperative or postoperative BREAST-Q scores may be individually influenced by age and BMI, these variables demonstrated no statistically significant effect on the average change between these scores. This literature review suggests that reduction mammoplasty delivers high satisfaction across a diverse range of patient populations, and additional prospective cohort or comparative studies gathering robust data on other patient factors would benefit this area of research.

Are Surgical Approaches Correlated With BREAST-Q Score Improvements After Reduction Mammoplasty? A Systematic Review.

BACKGROUND: Despite the commonly recognized benefits and drawbacks of each surgical technique for reduction mammoplasty, data on the influence of each surgical approach on patient quality of life and satisfaction remains limited. Our study aims to evaluate the association between surgical factors and BREAST-Q scores for reduction mammoplasty patients. METHODS: A literature review through August 6, 2021, was conducted using the PubMed database to select publications that used the BREAST-Q questionnaire to evaluate outcomes after reduction mammoplasty. Studies examining breast reconstruction, breast augmentation, oncoplastic reduction, or breast cancer patients were excluded. The BREAST-Q data were stratified by incision pattern and pedicle type. RESULTS: We identified 14 articles that met selection criteria. Among 1816 patients, the mean age ranged from 15.8 to 55 years, mean body mass index ranged from 22.5 to 32.4 kg/m 2 , and bilateral mean resected weight ranged from 323 to 1845.96 g. Overall complication rate was 19.9%. On average, satisfaction with breasts improved by 52.1 ± 0.9 points ( P < 0.0001), psychosocial well-being improved by 43.0 ± 1.0 points ( P < 0.0001), sexual well-being improved by 38.2 ± 1.2 points ( P < 0.0001), and physical well-being improved by 27.9 ± 0.8 points ( P < 0.0001). No significant correlations were observed when mean difference was modeled against complication rates or prevalence of superomedial pedicle use, inferior pedicle use, Wise pattern incision, or vertical pattern incision. Complication rates were not correlated with preoperative, postoperative, or mean change in BREAST-Q scores. A negative correlation was noted between the prevalence of superomedial pedicle use and postoperative physical well-being (Spearman rank correlation coefficient [SRCC], -0.66742; P < 0.05). The prevalence of Wise pattern incision was negatively correlated with postoperative sexual well-being (SRCC, -0.66233; P < 0.05) and physical well-being (SRCC, -0.69521; P < 0.05). CONCLUSIONS: Although either preoperative or postoperative BREAST-Q scores may be individually influenced by pedicle or incision type, there was no statistically significant effect of surgical approach or complication rates on the average change of these scores, and overall satisfaction and well-being scores improved. This review suggests that any of the main surgical approaches to reduction mammoplasty provide equally substantial improvements in patient-reported satisfaction and quality of life, but more robust comparative studies would strengthen this area of research.

The Potential of Transexamic Acid Use for Wide Awake Local Anesthesia No Tourniquet.

Tranexamic acid (TXA) is a drug commonly used to decrease intraoperative bleeding. Its use in various types of surgery is well defined; however, its use in plastic surgery and even more so, hand surgery is not as well researched. Concurrently, the use of wide-awake local anesthesia no tourniquet (WALANT) procedures has increased in popularity. As the use of WALANT increases, it comes to question whether TXA could be used as an alternative to epinephrine during WALANT procedures. This case involves a 33-year-old woman status-post motor vehicle collision. On examination, the patient sustained transection of the flexor digitorum profundus on both her left middle and ring fingers along with absent sensation to her left middle finger. Due to the surgical preference for vascular monitoring, TXA was used alternatively to epinephrine to control intraoperative bleeding during the tendon repairs. It was observed that TXA allowed for controlled bleeding, preservation of the surgical visual field, successful tendon repair, and postoperative success. The successful use of TXA in this case prompts further investigation as to whether TXA could be used as an alternative to epinephrine in WALANT procedures.

A Novel Algorithm for Defining the Mandibular Border.

SUMMARY: Techniques for defining the mandibular angle are a particular focus for patients around the world. Developing the desirable sharp contours is a combination of reducing bulkiness around the mandible while augmenting the border. Invasive techniques (e.g., face lifts and chin augmentation) can help define the mandible; however, younger patients are demanding more affordable and less invasive procedures. The "Nefertiti lift," masseter neurotoxin, buccal fat excision, mandibular border augmentation with filler, and liposuction of the neck can all be done in the office and will produce excellent results. If the loss of definition is due to superior soft tissue, the next step is to determine if this is based on anterior or posterior soft-tissue excess. Posteriorly, it is caused by masseter hypertrophy, and anteriorly, it may be because of an enlarged or full buccal fat pad in the lower cheek area. If the loss of definition is inferior, the next step is to again define if it is anterior or posterior. Anterior excess tissue can be corrected with liposuction of the neck along with energy-based skin tightening technology. Posteriorly, the inferior pull of the platysma can be blunted with neurotoxin. Finally, once the soft tissues are adequate, the mandibular border can be augmented with filler. In this article, the authors propose an algorithm for when to utilize each of these procedures while reviewing proper technique.

A Review of Venous Thromboembolism Risk Assessment and Prophylaxis in Plastic Surgery.

BACKGROUND: Venous thromboembolism is a significant cause of postoperative death and morbidity. While prophylactic and treatment regimens exist, they usually come with some risk of clinically relevant bleeding and, thus, must be considered carefully for each individual patient. METHODS: This special topic article represents a review of current evidence regarding venous thromboembolism risk, biology, and prevention in plastic surgery patients. The specific types and duration of available prophylaxis are also reviewed. The balance of venous thromboembolism risk must be weighed against the risk of hemorrhage. RESULTS: Though alternatives exist, the most validated risk assessment tool is the 2005 modification of the Caprini Risk Assessment Model. Controversies remain regarding recommendations for outpatient and low risk cosmetic patients. The authors additionally make recommendations for high-risk patients regarding the use of tranexamic acid, estrogen therapy, anesthesia, and prophylaxis regimens. CONCLUSION: Our profession has made great strides in understanding the science behind venous thromboembolism, risk stratification for patients, and prophylactic regimens; yet, continued studies and definitive data are needed.

The Role of the Buccal Fat Pad in Facial Aesthetic Surgery.

SUMMARY: Social media have triggered a buccal fat pad excision frenzy. Not surprisingly, there is tremendous appeal of having a slimmer lower face and more defined jawline after undergoing a small intraoral procedure under local anesthesia. Although this procedure is great for social media and seemingly beneficial for jawline aesthetics, the evidence remains limited as to whether or not this is an effective long-term solution. How much the buccal fat pad persists or diminishes as we age is an area of debate. However, the possibility of causing premature aging and midface distortion in the long run is disconcerting.

The Use of Peripheral Nerve Stimulation in Conjunction with TMR for Neuropathic Pain.

Targeted muscle reinnervation and regenerative peripheral nerve interfaces are increasingly utilized strategies to mitigate phantom and residual limb pain in amputees. These interventions are successful, yet often imperfect in completely ameliorating neuropathic pain following amputation. Implantable peripheral nerve stimulators are another tool in the armamentarium for management of neuropathic pain. These devices have been utilized adjacent to the spinal cord and more recently in the extremities with good results, and there has been additional interest in their utility for nerve regeneration. In this case report, we present the first reported case in the readily available literature of combining contemporary peripheral nerve strategies with an implantable peripheral nerve stimulator for postamputation neuropathic pain. The patient is a 72-year-old man who presented with severe neuropathic pain following prior below knee amputation with an osseointegrated implant and regenerative peripheral nerve interfaces. The authors performed targeted muscle reinnervation with intra-operative placement of a peripheral nerve stimulator. He did well after the procedure, and his pain improved with activation of the device. The most symptomatic nerve is targeted with the nerve stimulator, and it is placed adjacent to the nerve transfer(s). Combining these contemporary techniques may lead to improved prosthetic use and quality of life for these patients.

Targeted Muscle Reinnervation for Symptomatic Neuromas Utilizing the Terminal Anterior Interosseous Nerve.

Sensory nerve trauma at the level of the wrist can lead to debilitating neuromas. Targeted muscle reinnervation (TMR) is an effective therapy for the treatment of neuromas. Here we propose the use of the terminal anterior interosseous nerve (AIN) as a viable recipient for TMR. All superficial sensory nerves around the wrist, including the dorsal ulnar sensory nerve, the distal lateral antebrachial cutaneous nerve, the distal branches of the superficial branch of the radial nerve, and the palmar cutaneous branch of the median nerve were dissected in 2 cadaver specimens. The AIN branch to pronator quadratus was divided just distal to the final branch of flexor pollicis longus to preserve adequate length for TMR. The sensory nerves at the wrist were fully dissected to identify a viable location for coaptation to the AIN. After the cadaveric concept was demonstrated, the technique was successfully used in a clinical case. In summary, the distal AIN is a versatile recipient for TMR as a treatment of painful sensory neuromas at the level of the wrist, with minimal donor-site morbidity.

Recurrent Schwannomatosis of the Hand.

Background: Peripheral nerve sheath tumors (PNSTs) are neoplastic soft tissue masses generated from the abnormal proliferation of Schwann cells. Often, these tumors occur in isolation and are known as schwannomas or neurilemmomas. The presence of multiple schwannomas is known as schwannomatosis. The purpose of this article is 2-fold: (1) to review the relevant literature and describe a unique case of this rare condition; and (2) to emphasize salient clinical considerations in the diagnosis and treatment of schwannomatosis. Methods: In this report, we describe the case of a 52-year-old white man who presented with multiple recurrent soft tissue masses of the right hand. On initial presentation, he described pain across his right hand and index finger, which persisted despite numerous prior operations. The index finger had a flexion contracture around the location of the proximal interphalangeal joint, and there were multiple tender masses along the length of the finger and palm. Results: Segmental excision of the affected radial digital nerve was performed. A pulp flap based on contralateral neurovascular bundle resulted in a sensate, pain-free digit. Tissue pathology confirmed the diagnosis of multiple neurilemmomas. Conclusions: We report the success of a radial digital neurectomy in a patient with widespread neurilemmomas, who had previously excluded that painful digit from use. It was through careful consideration of the preoperative differential diagnosis, by valuing the preoperative imaging, and by considering all surgical options with specific attention paid to skin flap design that this good outcome of a fully sensate, pain-free, mobile index finger was achieved.

Stem Cells and Plastic Surgery.

Pluripotent stem cells can help recreate a variety of different tissues. Stem cells are already in use in a variety of ways in the medical field but plastic surgeons have particular interest because of the constant need to produce additional tissue or mold existing tissue. More and more commercial products are being marketed with far-reaching goals and some with proven and promising results. In this article, the authors discuss the basic science behind stem cells and the theories on how they work. They then discuss some active uses of stem cells that should be understood by all plastic surgeons. The reader should then have an understanding and basis to evaluate new technologies and commercial products as they develop.

Management of Microsurgical Patients using Intraoperative Unfractionated Heparin and Thromboelastography.

BACKGROUND: Maintaining optimal coagulation is vital for successful microvascular tissue transfer. The viscoelastic thromboelastography (TEG) is a modern and dynamic method to assess a patient's coagulation status. The aim of this study was to evaluate its diagnostic capabilities of identifying microvascular complications. METHODS: A retrospective chart review was conducted for the most recent 100 cases of abdominal free flap breast reconstruction of a single surgeon. Patient demographics, medical history, clinical, and operative details were documented. Thrombocyte counts, prothrombin time (PT), activated partial thromboplastin time (aPTT), and various TEG parameters were gathered for preoperative, intraoperative, and two postoperative time points. RESULTS: A total of hundred patients were identified, who underwent 172 abdominal-based free flaps for breast reconstruction. TEG was more dynamic compared with PT or aPTT and demonstrated borderline hypocoagulate values intraoperatively upon unfractionated heparin administration and hypercoagulate values postoperatively. In contrast, PT and aPTT demonstrated a continuously hypocoagulable state. Complications included five thrombotic events and three hematomas. The thrombotic cases had much steeper increases of TEG-G between surgery and postoperative day 2 (p = 0.049), while PT and aPTT failed to identify these patients. Of those, two resulted in flap loss (1.2%) that both occurred in patients with abdominal scars from previous surgery. CONCLUSION: The TEG is a useful adjunct for monitoring coagulation status in microsurgical breast reconstruction. When thrombosis at the anastomosis occurs, TEG correlates with a more rapid rebound from an intraoperative hypocoagulable state to a postoperative hypercoagulable state, when using the TEG. The TEG is a valuable tool for a more dynamic assessment of the patients' changing coagulation status.

Nerve Transfer versus Interpositional Nerve Graft Reconstruction for Posttraumatic, Isolated Axillary Nerve Injuries: A Systematic Review.

BACKGROUND: The purpose of this study was to compare functional outcomes between nerve grafting and nerve transfer procedures in the setting of isolated, posttraumatic axillary nerve injuries. METHODS: A systematic review was performed using the PubMed, Scopus, and Cochrane databases to identify all cases of isolated, posttraumatic axillary nerve injuries in patients aged 18 years or older. Patients who underwent axillary nerve reconstruction were included and categorized by technique: graft or transfer. Demographics were recorded, including age, time to operation, and presence of concomitant injuries. Functional outcomes were evaluated, including British Medical Research Council strength and range of motion for shoulder abduction. RESULTS: Ten retrospective studies met criteria, for a total of 66 patients (20 nerve grafts and 46 nerve transfers). Median time from injury to operation was equivalent across the nerve graft and nerve transfer groups (8.0 months versus 7.0 months; p = 0.41). Postoperative follow-up was 24.0 months for nerve grafting versus 18.5 months for nerve transfer (p = 0.13). Clinically useful shoulder abduction, defined as British Medical Research Council grade M3 or greater, was obtained in 100 percent of nerve graft patients versus 87 percent of nerve transfer patients (p = 0.09). Grade M4 or better strength was obtained in 85 percent of nerve graft patients and 73.9 percent of nerve transfer patients (p = 0.32). CONCLUSIONS: Significant differences in functional outcomes between nerve graft and transfer procedures for posttraumatic axillary nerve injuries are not apparent at this time. Prospective outcomes studies are needed to better elucidate whether functional differences do exist. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Post-tonsillectomy hemorrhage rates in children compared by surgical technique.

Despite the sheer number of pediatric tonsillectomies performed in the United States annually, there is no clear consensus as to which surgical technique is superior. One way to compare surgical techniques is to study the morbidity associated with each. We report postoperative hemorrhage rates, one of the frequently encountered major adverse events, as part of a retrospective chart review across four different surgical techniques. These surgeries involved either (1) Coblation, (2) Co-blation with partial suture closure of the tonsillar fossa, (3) diathermy, or (4) partial intracapsular tonsillectomy (PIT). Of the 7,024 children we evaluated, 99 (1.4%) experienced a postoperative hemorrhage that required a second surgery; hemorrhage occurred after 33 of the 3,177 Coblation-alone procedures (1.04%), 28 of the 1,633 Coblation with partial suture closure procedures (1.71%), 29 of the 1,850 diathermies (1.57%), and 9 of the 364 PIT procedures (2.47%). Statistical analysis of hemorrhage rates with each surgical technique yielded p values >0.05 in each case (Coblation alone and Coblation with partial suture closure: p = 0.29; diathermy: p = 0.47; PIT, p = 0.20). Based on these data, we conclude that none of these techniques is significantly superior in terms of decreasing the risk of post-tonsillectomy hemorrhage in children. Therefore, surgeons should continue to use the surgical procedure they are most familiar with to optimize recovery in the postoperative period.
