Regenerative Therapies for Basal Thumb Arthritis-A Systematic Review.

Basal thumb arthritis is a painful and debilitating pathology that can severely reduce a patients' quality of life. Common therapies include oral pain control, local steroid injections and/or surgery. Yet, therapeutic data on long-term improvement and even cartilage repair are scarce. This review aims to present the currently available literature on novel therapies for basal thumb arthritis, including platelet-rich plasma (PRP), fat grafting and phototherapy, and investigate their potential efficacy. The entire OVID database and PubMed were searched for studies containing the topics PRP injection, lipofilling, laser treatment and regenerative treatment for carpometacarpal arthritis. Seven studies on the effect of fat tissue on basal thumb arthritis were found. Four authors reported on PRP injections, one RCT examined a combinational treatment of PRP and fat grafting, another phototherapy for the thumb joint and one prospective trial on chondrocyte transplantation was found. Pain improvement and decreased impairment were reported in the majority of PRP and/or fat grafting studies as well as after chondrocyte implantation. Phototherapy did not significantly improve the condition. This review revealed that only limited data on regenerative therapies for carpometacarpal arthritis are currently available, yet PRP and lipofilling show promising results and merit further investigation.

Platelet-rich plasma for striae distensae: What do we know about processed autologous blood contents for treating skin stretchmarks?-A systematic review.

Striae distensae, also known as stretch marks, particularly associated with female sex, pregnancy, obesity, and/or hormonal change, are linear bands of benign dermal lesions. Although not posing any health risk, aesthetically unpleasing stretch marks can cause significant psychological distress among those affected. In abundance of therapeutic approaches, some literature sources proclaim platelet-rich plasma to be a promising treatment modality for striae distensae. We aimed to shed some light on the current literature evidence of platelet-rich plasma for treating stretch marks and performed an English literature analysis with two independent reviewers in accordance with PRISMA guidelines searching the PubMed and Web of Science databases in June 2019. Of the 12 found studies, 6 matched inclusion criteria. With no control groups in two, just two other reports used intraindividual comparisons, and all but one publication performed histopathological assessments. All studies observed clinical and subjective improvements without using validated scores or patient-reported outcome measures (PROMs). The main findings were that multiple treatments with platelet-rich plasma demonstrated increased epidermal thickness, rete ridges formation, and collagen/elastin formation, while decreasing the inflammatory cell infiltrate. The current literature evidence supporting the use of platelet-rich plasma for striae distensae is poor. We propose in this review an outline for a study protocol with intraindividual control groups, standardised scores, validated PROMs, and participant incentives to enhance the scientific power in future clinical trials.

Lessons Learned From Breast Implant Registries: A Systematic Review.

OBJECTIVE: Over several decades, numerous national and international registries on breast implants went online, aiming to collect prospective data to provide increased safety for patients and surgeons. We performed a review of all published data on breast implant registries to assess availability and quality of data and determine its usefulness and impact. MATERIALS AND METHODS: PubMed, Ovid, and Web of Science were searched to identify all articles containing breast implant registries in English language. The review was registered at PROSPERO (CRD42016041255) and performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. There was no limitation by publication date. RESULTS: Eight hundred ninety-five articles were identified; after removal of duplicates, 536 abstracts were screened on breast implant registries in plastic and reconstructive surgery. Unrelated articles, non-English articles, and not breast implant-related studies were excluded. Twenty breast implant registry-related articles met the inclusion criteria; 7 articles contained actual data on breast implants. Compared with international trends, only a minimal percentage of performed surgical breast augmentations is documented in registries, and the overall data quality and availability were low. CONCLUSIONS: Only a fraction of performed breast augmentations is documented properly in a registry. Currently, there are no published data based on a clinical quality registry. Sustained funding and reliable administrative governmental structures remain crucial to establish an adequate clinical quality registry for breast implants as currently launched in Australia to analyze outcomes and risk factors for an increased patient safety.

Three-Dimensional Evaluation of Static and Dynamic Effects of Botulinum Toxin A on Glabellar Frown Lines.

BACKGROUND: The use of injectable solutions for aesthetic purposes has increased tremendously, but lacks objective support. We aimed at assessing static and dynamic effects of botulinum toxin A (BoNTA) on glabellar lines by use of an objective three-dimensional methodology. METHODS: We prospectively collected three-dimensional stereographic photographs of two different facial expressions (pretreatment, 30 and 90 days posttreatment) in 21 patients, receiving a total of 20 units of BoNTA in both corrugator supercilii muscles. The primary endpoint was the three-dimensional static and dynamic surface irregularity, and secondary endpoints were the glabellar line scale and overall patient satisfaction. Blinded retrospective data analysis and statistical evaluation were performed with p < 0.05 considered statistically significant. RESULTS: Static glabellar lines (neutral facial expression) were significantly reduced by - 17% and - 24% on day 30 and 90 posttreatment, respectively (vs. pretreatment; both p < 0.0001). Dynamic glabellar frown lines (firmest possible bilateral eye closure) demonstrated a reduction of surface irregularity by - 26% and - 21% on day 30 and 90 posttreatment, respectively (vs. pretreatment; both p < 0.0001). The subjective dynamic glabellar line scale documented a statistically significant improvement on day 30 posttreatment (mean ± SD: 1.5 ± 0.8; p < 0.05) versus pretreatment (2.8 ± 1.0). Polled patients confirmed a subjective wrinkle improvement 90 days posttreatment. CONCLUSION: The presented setup detected even subtle changes of BoNTA treatment for facial wrinkling and is a promising asset for scientific evaluations of clinical studies analyzing the outcome and duration of efficacy of injectable solutions on the face.

Risk factors for recurrence of pressure ulcers after defect reconstruction.

Patients suffering from pressure ulcers remain to be a challenging task for nursing staff and doctors in the daily clinical management, putting-notably in the case of recurrences-additional strain on the constantly reduced resources in public healthcare. We aimed to assess the risk factors for the recurrence of pressure ulcers at our institution, a tertiary referral center. In this retrospective analysis of patients admitted to our division we identified risk factors for pressure ulcer recurrence. The hospital patient database search included all patients with a diagnosis of pressure ulcers of the torso and lower extremity. One hundred sixty-three patients were diagnosed with pressure ulcers and 55 patients with 63 pressure ulcers met our inclusion criteria. The 17 recurrences (27%) had an average follow-up of 728 days. Most presented with lesions of the ischial tuberosity (n=24). Recurrence was statistically associated with defect size (p = 0.013, Cox regression analysis), and serum albumin levels (p = 0.045, Spearman correlation), but no association was found for body mass index, bacterial profile, comorbidities, localization, previous surgery, or time-to-admission for reconstruction (all p > 0.05). Supported by the recent literature we identified factors like defect size to be associated with pressure ulcer recurrence, but not with time-to admission for reconstruction or number of previous debridements. Whether laboratory values like serum albumin levels were the cause, the result or associated with pressure ulcer recurrence warrants further investigation.

Minimal Undermining Suspension Technique (MUST): Combined Eyebrow and Mid-face Lift via Temporal Access.

BACKGROUND: Less downtime following esthetic interventions leads to the popularity of injectable solutions for facial rejuvenation treatments. Surgical interventions for esthetic purposes are usually associated with higher complication rates and longer recovery times when compared to less invasive treatments. Here we present for the first time a minimally invasive surgical technique for a simultaneous mid-face and eyebrow lift using one small temporal incision. MATERIALS AND METHODS: We prospectively studied patients who underwent facial rejuvenation using a minimal undermining suspension technique (MUST) in an outpatient setting. Postoperatively, surgical complications were classified according to the Clavien-Dindo classification. Preoperatively and at 12-month post-intervention, patient-reported outcomes were described using the FACE-Q questionnaire. Pre- and postoperative pictures were compared using MERZ Aesthetic Scales. RESULTS: Fifty-five patients (50 females and 5 males) with a mean age of 47 years were studied. The overall complication rate was 19%, whereas 18 patients (15%) developed an ecchymosis of the orbicular temporal region and two patients (4%) developed a dimple caused by the anchor of the suture. No displacements of the palpebral rim or injuries to the facial nerve were observed. Recovery time was in average 7 days and no long-term complications were seen. Both, the FACE-Q and the MERZ Aesthetic Scales showed significant improvements at 12-month post-surgery (p < 0.01). CONCLUSIONS: The MUST can be used as a minimal invasive procedure for facial rejuvenation with a short downtime and low complication rate. The discreet temporal access and the MUST dissector allowed a safe dissection of anatomical tissue planes to perform safely a mid-face and eyebrow lift. Further studies are warranted to prove long-term outcomes. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Severe forefoot infection complicated by Fusobacterium russii.

We present the first case of a complicated foot infection caused by Fusobacterium russii in Austria. F. russii is highly associated with mammals such as cats and dogs. Our case underlines the difficulties in isolation and identification of anaerobes and the pitfalls in antimicrobial treatment of polymicrobial infections.

Internet-based survey on current practice for evaluation, prevention, and treatment of scars, hypertrophic scars, and keloids.

No universally accepted standard for evaluation, prevention, and treatment of scars, hypertrophic scars, and keloids exists. Following development of a questionnaire, we performed a closed Web-based survey among burn centers. Server-based data collection was performed over 4 weeks and closed thereafter. The poll revealed emerging new treatment schemes, but the majority of participants adhered to evaluation (Patient and Observer Scar Assessment Scale, Matching Assessment of Scars and Photographs, Vancouver Scar Scale, two-dimensional photography) and prevention (silicone gel sheets and compression garments) strategies that were in line with the currently available recommendations from the literature. We noted a low penetration for the use of objective evaluation tools in our poll and detected differences in surgical approaches to keloids. Based on the results of our survey and the power of currently available clinical recommendations, we expect future guidelines to gain more evidence-based power, especially when more high-quality clinical trials with objective evaluation support, clearly defined disease entities, and therapeutic outcome factors have become available.

Simultaneous dermal matrix and autologous split-thickness skin graft transplantation in a porcine wound model: a three-dimensional histological analysis of revascularization.

Despite the popularity of a simultaneous application of dermal matrices and split-thickness skin grafts, scarce evidence exists about the process of revascularization involved. In this study, we aimed at analyzing the progression of revascularization by high-resolution episcopic microscopy (HREM) in a porcine excisional wound model. Following the surgical procedure creating 5 × 5 cm(2) full-thickness defects on the back, one area was covered with an autologous split-thickness skin graft alone (control group), the other with a collagen-elastin dermal matrix plus split-thickness skin graft (dermal matrix group). Two skin biopsies per each group and location were performed on day 5, 10, 15, and 28 postoperatively and separately processed for H&E as well as HREM. The dermal layer was thicker in the dermal matrix group vs. control on day 5 and 28. No differences were found for revascularization by conventional histology. In HREM, the dermal matrix did not appear to decelerate the revascularization process. The presence of the dermal matrix could be distinguished until day 15. By day 28, the structure of the dermal matrix could no longer be delineated and was replaced by autologous tissue. As assessed by conventional histology and confirmed by HREM, the revascularization process was comparable in both groups, notably with regard to the vertical ingrowth of sprouting vessels. The presented technique of HREM is a valuable addition for analyzing small vessel sprouting in dermal matrices in the future.

Using superficial fascial system suspension for the management of the mons pubis after massive weight loss.

Although an abundance of literature exists regarding frequently lifted body areas, there are few reports about body contouring of the mons pubis. Therefore, this paper describes the first clinical results from a new technique, which surgically lifts the mons pubis using superficial fascial system suspension. Fifty patients underwent a lower body lift, including a superficial fascial system suspension of the mons pubis. After a mean follow-up period of 16.9 months (range, 6-31 months), patients were evaluated by standardized preoperative and postoperative photographs using the Pittsburgh Rating Scale. In addition, all patients completed a Likert-type scale questionnaire pertaining to body satisfaction and other bodily changes. Scores from the Pittsburgh Rating Scale improved significantly (P=0.03) from 2.76 (0.43) [range, 1-3] preoperative to 0.5 (0.59) [range, 0-2] postoperative. Fifteen (30%) of the patients assessed the new contour as very good, 26 (52%) patients as good. Eight patients developed a temporary edema in the mons pubis and 1 patient developed an infected fascia suture granuloma, which had to be removed. A mons pubis lift with the aid of the superficial fascial system is a safe surgical technique, which can easily be integrated in body contouring surgeries of the torso.

Gram-Positive Bacteria Increase Breast Implant-Related Complications: Prospective Analysis of 100 Revised Implants.

BACKGROUND: Breast implant-related complications can be reduced by strict antiseptic precautions during insertion, but bacteria can often be found on implant surfaces on the occasion of revision surgery. The authors prospectively analyzed the association of bacteria found on breast implant surfaces with implant-related complications in breast implant revision cases. METHODS: The authors analyzed a total of 100 breast implant revisions in 66 patients between August of 2018 and January of 2021. Capsular swabs and capsular samples were taken intraoperatively. Analyses on the occurrence of bacteria and the occurrence of implant-related complications were performed. In addition, correlations between bacteria-contaminated breast implant surfaces and implant-related complications were performed. RESULTS: Implant-related complications (perforation, rupture, capsular contraction) were observed in 42 implant sites: eight unilateral and 34 bilateral cases. In total, 16 swabs showed positive bacterial growth, 10 of which were associated with a breast implant-related complication (χ 2 = x, y, and z; P = 0.006). The most common implant-based complication at contaminated prosthetics was implant rupture. The association of contaminated breast implants and implant rupture was statistically significant. CONCLUSIONS: The authors identified a correlation between implant complications and Gram-positive bacteria found on breast implant surfaces. The most common implant-based complication seen at simultaneously positive samples was implant rupture in 50% of the authors' cases. No capsular contraction or other complications were seen. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

The use of a polylactide-based copolymer as a temporary skin substitute in deep dermal burns: 1-year follow-up results of a prospective clinical noninferiority trial.

Deep dermal burns can be covered with different kind of materials and techniques; one of them is a polylactide-based temporary skin substitute. The aim of this study was to intraindividually compare its 1-year outcome with the results obtained by use of autologous skin grafts in patients suffering from deep dermal burns. A prospective noninferiority trial was designed in order to assess skin quality and scar formation by use of subjective (Vancouver Scar Scale; Patient and Observer Scar Assessment Scale) and objective (noninvasive cutometry) burn scar assessment tools. All items of the Patient and Observer Scar Assessment Scale, except vascularity, were found to be noninferior in the areas covered with the temporary skin substitute vs. autologous skin. Results of objective scar evaluation showed comparable viscoelastic parameters without reaching noninferiority. Overall, the outcome of deep dermal burns covered with a polylactide-based temporary skin substitute revealed satisfactory results in terms of scar formation and skin quality as compared with autologous skin. This paper supports its use in deep dermal burns, where autologous skin donor sites require either to be reserved for coverage of full-thickness skin defects in severe burns or to be saved for reduction of additional morbidity in selected patient collectives.

Optimal blood glucose control in severely burned patients: a long way to go, but one step closer.

Over the past years there has been a significant decrease in mortality and morbidity in patients suffering from severe burns due to improved burn wound management and approaches in critical care. Survival is no longer the exception, but unfortunately death still occurs. One of the key elements concerning state-of-the-art burn care is blood glucose control and insulin therapy; it is well known that burn-induced hyperglycaemia is associated with adverse clinical outcomes. However, controversy for insulin therapy and tight glycaemic control in critically ill and burn patients exists. The increased incidence of hypoglycaemia is the dominant argument against this treatment, because hypoglycaemia is also associated with an increased risk for death in critically ill patients. Taking all current data together, insulin therapy appears both a friend and a foe in the treatment of ICU patients. In order to overcome the limits of tight glycaemic control resulting from hypoglycaemic episodes, current efforts have been directed towards the development of protocols allowing for implementation of clinically feasible and safe guidelines. Among the strategies addressing this problem are closed loop techniques, which are supported by studies demonstrating their capability of exerting tight glycaemic control without the risk of developing hypoglycaemic episodes. Although closed loop techniques have become readily available, we require further evidence to ensure their safety in various ICU environments, notably in ICUs dealing with burn patients. Nonetheless, it is important to emphasise that glycaemic control and adequate insulin therapy are crucial factors for the final outcome (survival) and require our attention.

Characterization of biomaterials with reference to biocompatibility dedicated for patient-specific finger implants.

PURPOSE: The research was focused on determining basic mechanical properties, surface, and phase structure taking into consideration basic cytotoxicity analysis towards human cells. METHODS: Biological tests were performed on human C-12302 fibroblasts cells using 3D-printed Ti6Al4V alloy (Ti64), produced by laser-based powder bed fusion (LB-PBF) and Alumina Toughened Zirconia 20 (ATZ20), produced by lithography-based ceramic manufacturing (LCM). Surface modifications included electropolishing and hydroxyapatite or hydroxyapatite/zinc coating. Structure analysis was carried out using a variety of techniques such as X-Ray diffraction, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and confocal laser scanning microscopy (CLSM), followed by mechanical properties evaluation using nanoindentation testing. RESULTS: Samples subjected to surface modifications showed diversity among surface and phase structure and mechanical properties. However, the cytotoxicity towards tested cells was not significantly higher than the control. Though, a trend was noted among the materials analysed, indicating that HAp/Zn coating on Ti64 and ATZ20 resulted in the best biological performance increasing cell survivability by more than 10%. CONCLUSIONS: Hydroxyapatite coating on Ti64 and ATZ20 resulted in the best biological properties. Tested materials are suitable for in vivo toxicity testin.

BMI and Revision Surgery for Abdominoplasties: Complication Definitions Revisited Using the Clavien-Dindo Classification.

After body contouring surgery of the lower trunk (CSLT), the definition, rate (4%-70%), and documentation of complications vary. Objectives: We analyzed the effect of risk factors on the outcome based on the Clavien-Dindo classification (CDC) after CSLT surgery and polled postoperative satisfaction among patients. Methods: All patients undergoing CSLT from 2001 to 2016 were included and were classified according to the CDC for postoperative events. Statistical analysis included proportional odds logistic regression analysis. We polled patients to grade their satisfaction with the postoperative result and whether they would have the operation performed again. Results: A total of 265 patients were included: 60 (22.6%), 25 (9.4%), 28 (10.6%), and 21 (7.9%) were in CDC grades I, II, IIIa, and IIIb, respectively. A high preoperative body mass index significantly increased the odds for a postoperative event requiring revision surgery under general anesthesia (CDC grade IIIb, odds ratio 0.93, 95% confidence interval 0.89-0.97, P = 0.001). One-hundred twenty-eight patients (48.3%) participated in the poll: 101 (78.9%) were either happy or content with the postoperative results, and 117 (91.4%) would have the procedure performed again, including all nine patients with CDC grade IIIb. Conclusions: Our results confirm that a high body mass index is a statistically significant risk factor for requiring major revision surgery after CSLT. Despite being a complication prone intervention, postoperative satisfaction after CSLT was ranked favorably in our sample. We recommend that the CDC be used in all surgical specialties to evaluate complications and permit future comparability of pooled data.

Prospective evaluation of a single-sided innervated gluteal artery perforator flap for reconstruction for extensive and recurrent pilonidal sinus disease: functional, aesthetic, and patient-reported long-term outcomes.

BACKGROUND: Treating large and extensive pilonidal sinus disease is a challenging task. Long-term reports on flaps suitable for coverage of large, wide, local-excision defects are sparse. We prospectively evaluated data with a minimum 1-year follow-up of the use of a single-sided, innervated, superior gluteal artery perforator flap. METHODS: Twenty-one patients (1 woman, 20 men) with a median age of 26 years (min - max = 18 - 46) were included in the study period from September 2005 to April 2010. We recorded flap size, major and minor complications, hospital length of stay, impairment in activities of daily living, pain, aesthetic outcomes, and sensibility in the gluteal region (PSSD, pressure-specified sensory device) at 6 and 12 months postoperatively. RESULTS: The mean defect size (±SD) was 13.0 ± 1.9 × 8.6 ± 1.3 × 5.5 ± 1.2 cm (height × width × depth), and median length of hospital stay was 9 days (range = 7-11). Only two patients developed minor wound-healing complications. Visual analog pain scales significantly improved, with no pain detectable at 12 months postoperatively (p < 0.0001). The aesthetic appearance of the results was good in the majority of patients (61.9-85.7 %). PSSD showed gradual normalization, with retained sensibility in the flap area over 12 months postoperatively (p = 0.0232). During the median 36-month (range = 20-60) follow-up, we have not observed any recurrence in the operated area. CONCLUSIONS: The innervated superior gluteal artery perforator flap is a useful technique for covering large and recurrent pilonidal sinus defects following wide local excision and represents an excellent tool in the surgical armamentarium for achieving long-lasting outcomes in this young group of patients.

Influence of brachial plexus blockade on oxygen balance during surgery.

The combined effects of anesthesia, motor blockade, and chemically induced sympathectomy after brachial plexus blockade can have a beneficial impact, when applied in selected, isolated diseased states of the upper limb. With the aim of using the prolonged effects of brachial plexus blockade for a future therapeutic application, we demonstrated a dependable methodology of venous blood gas monitoring and confirmed an improved oxygen balance of the blocked versus nonblocked upper extremity in a controlled, prospective study in healthy patients undergoing elective hand surgery.

Adipose tissue engineering: three different approaches to seed preadipocytes on a collagen-elastin matrix.

BACKGROUND: Millions of plastic and reconstructive surgical procedures are performed each year to repair soft-tissue defects that result from significant burns, tumor resections, or congenital defects. Tissue-engineering strategies have been investigated to develop methods for generating soft-tissue. Preadipocytes represent a promising autologous cell source for adipose tissue engineering. These immature precursor cells, which are located between the mature adipocytes in the adipose tissue, are much more resistant to mechanical stress and ischemic conditions than mature adipocytes. To use preadipocytes for tissue-engineering purposes, cells were isolated from human adipose tissue and seeded onto scaffolds. Once processed, preadipocytes become subject to the human tissue act and require handling under much tighter regulations. Therefore, we intended to identify any influence caused by processing of preadipocytes prior to seeding on the reconstructed adipose tissue formation. MATERIAL AND METHOD: Human preadipocytes were isolated from subcutaneous adipose tissue obtained from discarded tissue during abdominoplasties of healthy men and women. Preadipocytes were divided into 3 groups. Cells of group I were seeded onto the scaffold directly after isolation, cells of group II were proliferated for 4 days before seeding, and cells of group III were proliferated and induced to differentiate before seeded onto the scaffold. A 3-dimensional scaffold (Matriderm, Dr. Otto Suwelack Skin and Health Care GmbH, Billerbeck, Germany) containing bovine collagen and elastin served as a carrier. Fourteen days after isolation, all scaffolds were histologically evaluated, using hematoxylin and eosin, anti-Ki-67 antibody, as well as immunofluorescence labeling with Pref-1 antibody (DLK (C-19), peroxisome proliferator-activated receptor gamma antibody, and DAPI (4',6-diamidino-2-phenylindole). RESULTS: Cells of all groups adhered to the scaffolds on day 21 after isolation. Cells of groups I (freshly isolated preadipocytes) and II (proliferated preadipocytes) adhered well and penetrated into deeper layers of the matrix. In group III (induced preadipocytes), penetration of cells was primarily observed to the surface area of the scaffold. DISCUSSION/CONCLUSION: : The collagen-elastin matrix serves as a useful scaffold for adipose tissue engineering. Freshly isolated preadipocytes as well as proliferated preadipocytes showed good penetration into deeper layers of the scaffold, whereas induced preadipocytes attached primarily to the surface of the matrix. We conclude that there might be different indications for each approach.

[Implementation of treatment by enzymatic debridement in burns: results of an interprofessional German-speaking expert workshop]. / Implementierung der Behandlung durch enzymatisches Debridement bei Verbrennungen ­ Ergebnisse eines interprofessionellen, deutschsprachigen Expertenworkshops.

INTRODUCTION: Since its introduction in 2013 Bromelain-based Enzymatic Debridement (ED) is increasingly used in burn centers. Published evidence shows its efficiency in eschar removal as well as a superiority in blood loss and necessity of further surgical procedures compared to standard-of-care. While the procedure is safe and shows reliable results in experienced hands, some practical and logistical issues must be challenged that are not described sufficiently in available literature. METHOD: A multi-professional panel, consisting of experienced users of ED from German-speaking burn units has been invited to an expert workshop. Topics concerning indication, definition of treatment pathways, practical issues, post-treatment and handling of complications have been coordinated in advance to allow discussion during the workshop. RESULTS: To each topic practical recommendations were developed and consented. Summarizing key messages have been additionally highlighted. They aim on helping to achieve optimal results after establishing the technique by new users as well as optimizing results by experienced users. Amongst others, the resulting recommendations deal with indications for ED beyond the classic domain, different treatment pathways depending on burn depth and primary result after ED with adapted post-treatment, management of treatment failure and implementation of infrastructural conditions. DISCUSSION: While efficiency of ED as well as superiority in some aspects of treatment of burn wounds could be shown in available literature, user-oriented recommendations for practical implementation are scarce. Although the recommendations and experts opinions published here are only partly evidenced based, they are still based on the pooled experienced of the panelists that easily outnumbers the cases published in literature so far and allow valuable support for a successful implementation of the technique.

Long-term outcomes of web creep, scar quality, and function after simple syndactyly surgical treatment.

PURPOSE: Syndactyly is the second most common congenital malformation of the hand, and reports of the incidence of web creep after surgery vary. To evaluate our outcomes of simple syndactyly surgical release, we conducted a retrospective analysis of patients treated between January 1965 and December 2007. METHODS: After matching for inclusion criteria, we recruited 19 patients with 26 affected web spaces for clinical examination. Outcomes evaluation included grading of web creep, Vancouver Scar Scale, assessment of complications and subjective patient analysis, range of motion, degree of finger abduction, power, and 2-point discrimination. Mean age at follow-up was 18 years (range, 6-50 y), with a mean age of 4.4 years (range, 7 mo to 15 y) at surgery and mean follow-up of 11.5 years (range, 5-35 y). Surgical management consisted of palmar and dorsal triangular skin flaps for creation of the new commissure, and multiple zigzag incisions for separation of digits. For tension-free closure, full-thickness skin grafts were harvested as needed. RESULTS: We observed web creep up to the proximal third of the distance between palmar metacarpophalangeal and proximal interphalangeal joint crease in 2 web spaces. All other web spaces had either a soft web equivalent to the contralateral (unaffected) side (n = 13) or no web advancement with thickening of the interdigital space (n = 11). The scar quality as assessed with the Vancouver Scar Scale revealed a height below 2 mm in 24 of 26 web spaces, with close to normal to supple pliability in 20 of 26 web spaces. There were no considerable differences for range of motion, degree of finger abduction, power, or 2-point discrimination between the affected and unaffected sides. In 17 of 24 cases in which full-thickness skin grafts from the groin region were used, patients reported commissural hair growth in the grafted region. CONCLUSIONS: Evaluation of the long-term outcomes of surgical treatment for simple syndactyly at our institution demonstrated a low incidence of web creep. When choosing the groin as a donor area for full thickness skin grafts, we recommend harvesting from the lateral third of the inguinal crease, to avoid esthetic compromise associated with the beginning of hair growth in puberty. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
