RESUMO
Syndactyly release aims to address skin deficits by resurfacing web spaces and sides of digits to allow independent digital motion while minimizing the risk of web creep and scar contractures. Conventional methods include the use of a dorsal and interdigitating flaps with full-thickness skin grafts. More recently, there have been several descriptions of "graftless" syndactyly release without skin grafts, thus avoiding a further (usually distant) donor site. However, the indications of when and when not to use these techniques remain unclear. In addition, the inevitable scarring from extra recruitment of local adjacent skin is perhaps underemphasized. In this article, we revisit the trilobed flap technique which serves to balance the amount of skin needed for resurfacing digits while minimizing local donor site scarring. The geometry and nuances of the flap inset are illustrated in detail to guide those embarking on this technique. The trilobed syndactyly release technique is a reproducible, safe, and reliable method for the release of simple syndactyly.

PURPOSE: Treatment for polysyndactyly of the toes aims at cosmetic improvement but the lateroplantar rotation of the new fifth toe remains challenging. This study evaluated our novel surgical procedure for postaxial polysyndactyly of the toes. MATERIALS AND METHODS: Patients with postaxial polysyndactyly involving the fourth, fifth, and sixth toes treated in 2007 to 2017 with a minimum follow-up duration of 1 year were retrospectively investigated. Our aims of surgery for this condition were to avoid excessive lateroplantar rotation of the new fifth toe by using a proximally elongated plantar "shark-fin flap" and to make the tip of this toe appear to be naturally pointing inward by using the dog-ear component of the flap on the tip of the toe. The excess skin of the shark-fin flap was grafted onto the lateral surface of the fourth toe. Lateroplantar rotation of the fifth toe in these patients was compared with that in photographs of the feet of 96 normal 4-year-old children. RESULTS: A total of 11 feet in 10 patients (6 male, 4 female; mean age 1.3 years) were analyzed. Syndactyly between the fourth and fifth toes was complete in 3 feet, incomplete at the level of the distal interphalangeal joint of the fifth toe in 5, and incomplete at the level of the proximal interphalangeal joint of the fifth toe in 3. Lateroplantar rotation of the fifth toe, evaluated by the mean angle between 2 intersecting lines extending from the proximal nail fold of the third and fifth toes, was 25 ± 10° in normal feet and 0 ± 12° in operated feet with polysyndactyly. The absolute left-right difference in this angle was 7 ± 5° in normal children and 22 ± 12° in patients with polysyndactyly. Valgus deformity of the new fifth toe improved in all patients during a mean postoperative follow-up of 3.8 years. CONCLUSIONS: Using our procedure, no excessive lateroplantar rotation has been observed when the tip of the fifth toe is inclined inward using a dog-ear flap component. This procedure could be useful in patients in whom the cosmetic outcome is a priority.

BACKGROUND: Palmar finger or pulp defects require coverage with glabrous tissue to achieve a good match with the lost tissue. The management of multiple finger palmar or pulp defects is challenging because these defects may not always be suitable for local or pedicled flaps. In such situations, syndactylizing free or pedicled flaps can be used. PATIENTS AND METHODS: We evaluated the results of free glabrous flaps syndactylizing across multiple finger defects. The two flaps used were the superficial branch of the radial artery (SUPBRA) flap and hypothenar free flap. Seven syndactylized glabrous free flaps were used to cover the defects in 16 fingers. The functional results and complaints were also assessed. RESULTS: Mean flap size was 14.35 cm2. Six flaps survived. Postoperative evaluation data were obtained for the 13 fingers. All the patients returned to their previous work. All patients had a diminished protective sensation of at least 4.31 according to the SWM test. The mean two-point discrimination score of the patients was 9.9 mm (7-14). One finger had a PIP joint flexion contracture of 30°, no donor-site complaints were observed. CONCLUSION: The advantages of these flaps include single operation site, strong glabrous tissue coverage, low risk of flexion contracture, and adequate tissue size for large defects. Disadvantages include two-stage and complex microsurgical operations, prolonged treatment, and hospital stay.

INTRODUCTION: Foot-syndactyly has long been managed through conventional surgical procedures, each having its own distinct advantages and drawbacks. While these methods, which do not require skin grafts, exhibit a lower incidence of long-term complications, they lead to undesirable scarring on the dorsal side of the foot and reduced patient satisfaction. In this study, we introduce an innovative technique involving an intermetatarsal plantar flap, supported by an anatomical investigation and clinical application. METHODS: Eight freshly preserved lower limbs were injected with colored latex to examine the cutaneous vessels on the plantar surface, a skin-flap was designed in an elliptical shape to address first web conjoined toes. The flap was extended from the center of each affected ray measuring ~30% of the sole's length. Using the mentioned novel approach, a flap was created and dorsally extended with a straight incision to release bilateral simple foot-syndactyly in an 8-year-old child presented with Apert's Syndrome. RESULTS: We identified cutaneous branches originating either from the medial plantar vessels or the lateral proper artery of the hallux. On average, the mean number of cutaneous branches found over the first intermetatarsal web spaces was 5.8 (ranging from 5 to 8) most of them originating from medial plantar vessels with a mean of 5.1 branches (range 4-6) while proper lateral great-toe digital artery provided a mean of 0.6 branches (range 0-2). Intra-operatively, in our patient, advancing the plantar flap ensured complete coverage of the commissure, obviating the necessity for skin grafts. Incisions healed uneventfully and a wide first web was obtained. Over a 15 months follow-up, no complications were observed. CONCLUSIONS: Our findings suggest that the skin-graftless first web release of syndactyly using a plantar intermetatarsal flap is a reliable and straightforward procedure with good cosmetic results, offering a promising alternative to conventional techniques. LEVEL OF EVIDENCE: Therapeutic IV.

Syndactyly reconstruction often times leaves areas of skin deficit that require coverage for healing. Numerous techniques have been reported to address the deficits, including graftless technique, which utilizes mobilization of adjacent skin for coverage, full-thickness skin grafting, and skin substitute grafts. The technique described here demonstrates the ease of the use of skin substitutes for coverage in syndactyly reconstruction and reports the expected outcomes.

Little is known about functional outcomes in children with treated lower extremity polydactyly (LEP). No classification system has been shown to be prognostically useful for functional outcomes. This study investigates whether children with treated LEP learn to walk at an age comparable to the population and whether the SAM (severity of syndactyly, axis deviation and metatarsal involvement) classification system is prognostically useful. In a retrospective cohort of 18 patients, we tested for associations between patient characteristics and SAM scores, age at learning to walk, and ability to fit off-the-shelf shoes. The proportion of children with treated LEP able to walk at 18 months of age was compared with the general population. We found no association between the age at which the 17 participants learned to walk and the severity of syndactyly (p = .214), axis deviation (p = .723) and metatarsal involvement (p = .781), nor between the proportion of patients able to wear off-the-shelf shoes compared to those requiring extra wide off-the-shelf shoes and the severity of syndactyly (p = 1.000), axis deviation (p = 1.000) and metatarsal involvement (p = 1.000). We found a trend between older age at surgery and the need for extra wide off-the-shelf shoes (OR = 1.008, p = .080). We found no significant difference in the proportion of children able to walk at 18 months between our patients (proportion = 1.00) and the general population (proportion = 0.95) (p = 1.000). We found no significant association between different SAM scores and functional outcomes, and none in the proportion of children able to walk at 18 months between treated LEP patients and the general population.

The aim of this study was to explore the feasibility of using a web index to measure web creep after syndactyly surgery. A total of 19 hands in nine children (six preoperatively and 13 immediately postoperatively) underwent measurement of their web position. A preliminary study confirmed that the web index measured on the child's hand at the time of surgery was similar to that measured on photographs taken at the same time. Subsequently, an intra- and inter-observer error rate found excellent agreement among four observers measuring the web index using photographs. Of 13 postoperative webs using a winged central rectangular web flap without skin grafting, 12 were re-measured using photographs at an average of 88 months (range 78 to 96) after surgery. There was evidence of minor web creep in one web only. Our study demonstrates the efficacy of web index calculation on photographs to measure web position in children after syndactyly surgery. The study also demonstrates the effectiveness of the graftless winged central rectangular web flap technique in avoiding web creep.Level of evidence: IV.

We present our results of one-stage resurfacing following syndactyly release with the Pelnac™ artificial dermal substitute. From 2016 to 2020, raw areas after digit release were restored with an artificial dermal substitute in 145 webs from 62 patients (average age, 33.1 months) including 65 simple incomplete web spaces, 29 simple complete web spaces, 20 complex complete web spaces, and 31 complex complicated web spaces. Fourteen patients were syndromic. The average follow-up period was 33.4 months (range, 7-55 months). Postoperative outcomes assessed as according to the Vancouver scar scale (0-14) averaged 1.8 (range, 0-11) and web creep score (0-5) averaged 0.7 (range, 0-4). Patient- and family-provided visual analog scale scores averaged 1.1 (range, 0-10) for appearance. In conclusion, the Pelnac™ artificial dermal substitute is a minimally invasive, simple, and effective option for one-stage resurfacing of defects in syndactyly release.

BACKGROUND: To explore the clinical efficacy of using tongue-shaped flaps and advancement flaps to reconstruct the fingertips in congenital syndactyly patients with osseous fusion of the distal phalanges. METHODS: From January 2016 to January 2019, 12 patients with congenital syndactyly, involving 30 digits in total, presented to our hospital and were surgically treated with tongue-shaped flaps, as well as with advancement flaps to reconstruct the fingertips. The flap infection rate, necrosis rate and any other early complications were recorded. Fingertip aesthetics were reported according to the modified Bulic scale. A questionnaire was used to assess the satisfaction of the patients' family members. RESULTS: All cases were thoroughly reviewed. The postoperative period for inclusion in this study ranged from 36 to 60 months, with an average follow-up time of 45 months. During this period, no complications such as infection and/or necrosis of any flap were observed. Significant improvements in finger aesthetics and functioning compared to preoperative values were observed in most cases. Based on the modified Bulic scale, of 30 fingertips, an excellent result was obtained for 3, a very good result for 13, a good result for 13 and a poor result for just 1. Family members were satisfied with the treatment outcome. CONCLUSIONS: This technique employing tongue-shaped flaps and advancement flaps to reconstruct fingertips is effective, which enables the attainment of favourable aesthetic and functional outcomes in congenital syndactyly patients with osseous fusion of the distal phalanges.

INTRODUCTION: Synpolydactyly is a rare congenital anomaly characterized by syndactyly and polydactyly in the central hand. Limited treatment guidelines exist for this complex condition. METHODS: A retrospective review of synpolydactyly patients was conducted at a large, tertiary pediatric referral center to describe our surgical experience and evolution of management. The Wall classification system was used to categorize cases. RESULTS: Eleven patients (21 hands) with synpolydactyly were identified. Most of the patients were White and had at least one first-degree relative who also had synpolydactyly. The Wall classification yielded the following results: 7 type 1A hands, 4 type 2B hands, 6 type 3 hands, and 4 uncategorizable hands. Each patient had an average of 2.6 surgeries and an average follow-up time of 5.2 years. The rates of postoperative angulation and flexion deformities were 24% and 38%, respectively, with many of these cases also demonstrating preoperative alignment abnormalities. These cases often required additional surgeries including osteotomies, capsulectomies, and/or soft tissue releases. The rate of web creep was 14% with 2 of these patients requiring revision surgery. Despite these findings, at the time of final follow-up, most patients had favorable functional outcomes, were able to engage in bimanual tasks, and were able to perform activities of daily living independently. CONCLUSIONS: Synpolydactyly is a rare congenital hand anomaly with a significant degree of variability in clinical presentation. The rates of angulation and flexion deformities as well as web creep are not insignificant. We have learned to prioritize correcting contractures, angulation deformities, and skin fusion, over simply trying to delete the "extra" number of bones as this may destabilize the digit(s).

INTRODUCTION: Dorsal hand skin flaps have been described in order to avoid digit skin grafting in syndactyly release. Although these skin-graftless techniques present a lower rate of long term complications, they result in unsightly dorsal scarring and worse patient satisfaction. We describe a novel technique using an intermetacarpal palmar flap by performing an anatomic study and clinical application. MATERIALS AND METHODS: Ten colored-latex-injected fresh upper limbs were used to study the palmar cutaneous perforators to second to fourth intermetacarpal space skin flaps designed elliptical, its width extending from the center of each involved ray and measuring 40%-50% the length of the palm. RESULTS: The anatomical study revealed a mean 2.77 (range 1 to 4) cutaneous perforators originating from either the common or proper digital vessels for every intermetacarpal space and measuring 0.4 mm (range 0.3 to 0.5 mm) in diameter. CLINICAL APPLICATION: This flap, measuring a mean of 21.5 mm (range 20 to 23 mm) in length and 9.5 mm (range 9 to 10 mm) in width, was used to release simple syndactylies in three patients of mean age 24 months (range = 18-30 months). After skin incision, cutaneous septa to the digital canal were released to permit flap advancement to the web space. Cutaneous perforators were not dissected. Intra-operative palmar-flap advancement provided commissure coverage in all children with no skin grafts needed. Over a mean follow-up of 15 months, no complications occurred, mean palm scar VSS was 2.4 (range 2 to 3) while it was 3 (range 3 to 3) for the commissure scars. CONCLUSIONS: Skin-graftless syndactyly release using a palmar intermetacarpal flap seems both reliable and easy-to-perform. LEVEL OF EVIDENCE: Therapeutic IV.

We assessed the appearance and cosmetic impact of surgery in congenitally different hands in Finland. A questionnaire was sent to 1165 respondents (786 female) with a mean age of 33 years (range 3-84). Participants were shown nine image pairs and seven pairs of pre- and postoperative images twice in a random order and asked to choose the more cosmetically pleasing one. We found that the appearance and number of fingers had an important aesthetic role, with higher number and more normal appearing digits consistently scoring higher than its counterpart (range 59-99%). Postoperative appearances were perceived as better than preoperative ones in syndactyly (98%), thumb duplication (92%), cleft hand (93%) and radial dysplasia (99%). Toe transfer and pollicization had little impact on cosmesis. This study demonstrated that surgery could improve cosmesis in congenitally different hands and overall, most respondents prefer an appearance that is as close as possible to normality. Level of evidence: IV.

The current surgical strategy for syndactyly is multistage operations in which every other web is released, leaving adjacent webs unoperated for the next stage to avoid a presumed possible digital vascular compromise. In this series, we present our experience with single-stage multiple syndactylies release. A total of 7 patients, including 2 patients with bilateral hand involvement, were included. Dorsal and volar triangular flaps were created for commissure reconstruction, and zigzag manner volar and dorsal incisions were made to release the webbed fingers. Sterile thermoplastic splints were molded directly over the skin grafts without any dressing or tie-over. Following the surgical operation, minimal flexion contracture was seen in three patients that needed future correction procedures. Cosmesis and functional outcome were acceptable. This study shows that the release of all webs in 1 setting can be accomplished by no vascular compromise, and there is no need for a preoperative vascular imaging study.

With the same clinical picture, different pathological changes must be expected in congenital malformations of the hand. Therefore, knowledge of these pathologies is crucial for planning the surgical approach. The approaches to common malformations are dealt with as examples. These include the double thumb and the syndactyly.In the case of the double thumb with an asymmetrical contour, the result is improved by augmenting parts of the redundant double thumb. In this case, a different incision is required than in simple resection.In the frequently performed syndactyly separations, there are many techniques that have been proven to achieve a good result. But only if principles such as local displacement flap plasty for commissure formation, tension-free wound closure, no longitudinal incisions and no bilateral preparation of a finger are observed here too. If it can be assumed preoperatively that a good surgical result cannot be achieved with the conventional technique of syndactyly separation, pre-treatment using an external fixator for transverse soft tissue distraction is the method of choice.The timing of surgery takes into account not to disturb the motor development of the affected person.

The necessity for early surgical correction of Apert hands for the overall child development has been highlighted repeatedly in older literature. Nevertheless, uncertainties regarding the time and the scale of the initial surgical treatment still remain. While in former times there were no regular follow-ups after the syndactyly release, we now know that during growth bony changes will develop in the Apert hand requiring regular check-ups and, in some cases, revision surgeries. Affected parents need comprehensive clarification about a clear and time-efficient therapeutic concept. This review article describes our actual concept treating Apert hands.

A comprehensive summary of recent knowledge in syndactyly (SD) is important for understanding the genetic etiology of SD and disease management. Thus, this review article provides background information on SD, as well as insights into phenotypic and genetic heterogeneity, newly identified gene mutations in various SD types, the role of HOXD13 in limb deformities, and recently introduced modern surgical techniques for SD. This article also proposes a procedure for genetic analysis to obtain a clearer genotype-phenotype correlation for SD in the future. We briefly describe the classification of non-syndromic SD based on variable phenotypes to explain different phenotypic features and mutations in the various genes responsible for the pathogenesis of different types of SD. We describe how different types of mutation in HOXD13 cause various types of SD, and how a mutation in HOXD13 could affect its interaction with other genes, which may be one of the reasons behind the differential phenotypes and incomplete penetrance. Furthermore, we also discuss some recently introduced modern surgical techniques, such as free skin grafting, improved flap techniques, and dermal fat grafting in combination with the Z-method incision, which have been successfully practiced clinically with no post-operative complications.

Background: Syndactyly is one of the commonly encountered congenital hand anomalies. However, there are no strict guidelines regarding the timing of surgical release. The aim of this study was to investigate the age and factors associated with syndactyly release in the United States. Methods: A retrospective analysis of the California and Florida State Ambulatory Surgery and Services Databases for patients aged 18 years or younger who underwent syndactyly release surgery between 2005 and 2011 was performed. Demographic data that included the age at release, gender, race and primary payor (insurance) was collected. A sub-analysis was performed to compare the demographic characteristics between those patients undergoing syndactyly release before 5 years of age ('Early Release') and at (of after) 5 years ('Late Release'). Results: A total of 2,280 children (68% male, 43% Caucasian) were identified. The mean age of syndactyly release was 3.6 years, and 72.9% of patients underwent release before the age of 5 years. A significantly larger proportion of females (p = 0.002), and Hispanics and African Americans (p = 0.024), underwent late release compared to early release. Additionally, a significantly higher percentage of patients undergoing late release utilised private insurance (p = 0.005). However, the actual differences in gender, race and primary payor were small. Conclusion: The majority of syndactyly releases were performed before school age, which is the primary goal in the management of syndactyly. While gender and racial disparities in the surgical treatment of syndactyly may exist, the differences in the present study were relatively small. Level of Evidence: Level III (Therapeutic).

Congenital syndactylies are frequent congenital malformations of the hand. They can be an isolated finding or they can be found in association with other polymalformative syndromes. Several surgical techniques used to treat them have been described in the literature. The most used is the dorsal commissural omega-flap technique. We here report a study of 18 patients with congenital syndactyly, with multiple involvement in several cases, whose data were collected at the Department of Orthopedics and Traumatology of Sfax (Tunisia). All patients were operated using the dorsal commissural omega-flap technique. We operated 42 commissures in 18 patients. The average age of patients was 7 years. Only 3 patients had syndromic forms. Six of these patients were operated in two stages. For scar quality, mean OSAS score was 11.47 (11.35 for simple types and 12 for complex types). All patients with complex types had long-term complications (100%). Six patients with simple types out of 14 had complications (42.85%). The management of congenital syndactylies is surgical. It is important to provide parents with accurate information on the essential role of follow-up appointments in order to avoid complications in the short and the long term.
