Abstract
This study evaluates the long-term donor site outcomes after second toe transfers for congenital hand differences performed during childhood. In total, 25 toe transfers in 18 patients were followed up for a mean period of 17.4 years. We examined the patients clinically, radiologically and with a gait analysis system. Patient-reported outcome measures were collected. The patients were asymptomatic and there were no problematic clinical or radiological findings. Patients expressed high levels of satisfaction. The results were consistent, regardless of the resection level in the toe transfer or whether the operation was unilateral or bilateral. No postoperative complications or late reoperations on the foot were observed.Level of evidence IV.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
This study evaluated how Apert hand syndactyly presentations and reconstructive techniques influence reconstruction outcomes. All cases at a major paediatric hospital between 2007 and 2022 were analysed, including 98 web space reconstructions in 17 patients. Overall, 62% of hands developed complications and 15% required revision surgery. Upton hand type was significantly associated with postoperative complication incidence, specifically including range-of-motion deficits, flexion contracture, web creep and revision surgery. More severe syndactylies may benefit from additional measures to reduce complications. Rectangular commissural flaps showed 1.9 times greater complication risk than interdigitating triangular flaps, including 11.2 times greater risk of web creep. Zigzag volar finger flaps showed 1.8 times greater complication risk than straight-line incisions, including 3.8 times greater risk of web creep. Our study showed that interdigitating triangular commissural flaps and straight-line volar finger incisions are preferable to rectangular commissural and zigzag finger flaps in most cases of Apert hand syndactyly to minimize complications.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
Various surgical techniques have been described for the release of syndactylized fingers. In our experience, the omega flap technique, which includes a dorsal truncated flap and an anchor incision on the volar side, stands out as a good technique to release syndactyly. Incidentally, in symbrachydactyly also, the fused digits can be released using this technique. Despite this, we could find no reference in the recent years. We would like to stress the ease and importance of this technique, hoping many practicing hand surgeons will benefit from this. Our purpose was to revisit this technique and expose it to the younger generation of hand surgeons. We have operated on 20 cases of syndactyly of different types-simple, compound, and complex-and 5 cases of symbrachydactyly. In all cases, the omega flap on the dorsum and anchor incision on the volar aspect of the finger forming 2 lateral palmar flaps were used. The release of syndactyly was satisfactory in all patients. There was no flap necrosis. None of these cases have required secondary surgery because the primary releases were adequate. Release of syndactyly had been a problem for centuries. Awareness of the disability was insufficient in earlier days; currently, they seek early medical care. The release should be complete. These children must be able to achieve the form and function of the hand, and additionally precision to work. We believe that the use of omega flap and anchor flap is a good procedure for syndactyly release.

Abstract
RATIONALE Triphalangeal thumb (TPT) is a rare congenital malformation where the thumb has three phalanges instead of two. Syndactyly is a condition in which children are born with fused or webbed fingers. The combination of TPT, Syndactyly, and thumb duplication is extremely rare, especially when these deformities are combined in one hand. PATIENT CONCERNS Hand abnormalities and polydactyl have been reported in a 1-year-old boy. DIAGNOSIS A clinical examination reveals two thumb duplications, finger fusion (Syndactyly), and a thumb with three phalanges (TPT). The diagnosis was based on clinical findings and an X-ray image of the hand. INTERVENTIONS The Z-plasty method was used to remove the adhesion between the thumb and forefinger, as well as the removal of the medial and distal phalanx of the thumb's medial tip. OUTCOMES The patient was followed for 2 months and found him in good health. To authors' knowledge, we described an unusual case from Syria, considered the first in medical history. LESSONS LEARNED General and plastic surgeons should be aware about this unusual mix of the three abnormalities. The family history must also be carefully investigated to explore the occurrence of hereditary illnesses.

Abstract
Congenital syndactylies account for 1 to 2 out of 2000 birth defects. Although several types of syndactylies exist, we only studied embryonic syndactylies. The goal of our study was to compare 2 types of coverage flap for the reconstruction of the finger web spaces: a volar flap described by Blauth and a dorsal flap described by Gilbert. Between 1993 and 2015, children affected by simple and complex syndactylies (partial or complete) were treated in 2 french pediatric hospitals and were selected for our analytic, comparative, retrospective review. The 2 hospitals used different surgical techniques: one used a volar flap described by Blauth and the other a dorsal flap described by Gilbert. The children were followed up to look for signs according to the stages of the Classification of Withey and to evaluate a global result according to the score of Withey. Our secondary criteria of judgement were the aspect of the surgical scar according to the VSS (Vancouver Scar Scale) and the satisfaction of the parents and children. The age of the children, need for a surgical revision and time of last follow- up were also studied. We found statistically significant differences between group I (volar flap) and group II (dorsal flap) in favor of the volar flap: higher scores of Withey (even when the number of commissures was increasing) and better VSS (regardless of the number of web spaces treated). There was no statistically significant difference between the 2 groups in terms of age, follow-up, or rate of surgical revision. All in all, the volar flap presented less sequelae in terms of scar retraction. Regardless of the flap used, the cosmetic results of the full-thickness skin graft used impacted the result both on the receiving site (dyschromia, hairiness) and the donor site.

Abstract
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.

Abstract
BACKGROUND Web creep is the most common long-term complication requiring revision after syndactyly surgery; however, few methods have been reported. The aim of this study was to introduce a newly designed asymmetric dorsal gull wing flap to reconstruct web for the postoperative web creep. METHODS A retrospective analysis was performed for 20 patients from January 2016 to May 2019. Sex, age, original malformations, original surgical procedure, complications, time between the 2 operations, operation records, preoperative and postoperative photographs, and Withey score were reviewed. RESULTS Eleven boys and 9 girls with average age of 60.65 ± 44.76 months underwent revision. Twenty-nine web spaces were affected (web creep, 12 cases; web creep and scar contracture, 17 cases). The original surgical procedure consisted of syndactyly separation in 15 cases, syndactyly separation with a full-thickness skin graft in 5 cases. There was 1 case of postoperative infection. All patients received an asymmetric dorsal gull wing flap and a zigzag incision, 15 patients received an additional full-thickness skin graft. The average time interval between the 2 operations was 34.60 ± 35.94 months. The follow-up time was 34.30 ± 20.73 months. No complications were noted, none of the patients redeveloped web creep. The median values for web creep, flexion-extension deformity, total Withey scores in the postoperative period were significantly lower than the preoperative values. The appearance and function of all digits were good. CONCLUSIONS The asymmetric dorsal gull wing flap is a good choice for web reconstruction when web creep is caused by syndactyly surgery.

Abstract
INTRODUCTION Syndactyly has a cosmetic, functional, and psychosocial impact, and surgical treatment is indicated in most cases. This study aimed to retrospectively identify whether patients undergoing surgical release of syndactyly younger than 1 year presented different results compared with those operated older than 1 year. METHODS Patients were assessed through photographic records by 3 independent specialist surgeons for the quality of scar, presence of web creep, rotational, flexion-extension, and lateral flexion deformities using the Withey score. RESULTS Thirty-four patients were included in the study, totaling 51 commissures operated. The score was higher in the group operated younger than 1 year (5.83 ± 2.39) compared with the group older than 1 year (3.94 ± 1.93), being statistically significant, with a P value of 0.011. CONCLUSIONS Children with syndactyly operated younger than 1 year have worse postoperative outcomes measured by the Withey score than those operated older than 1 year.

Abstract
BACKGROUND The aim of the study was to present a new operative technique for aesthetic and anatomic reconstruction of polysyndactyly of the fifth toe fused with the fourth toe. METHODS Surgery was performed in 86 feet in 73 patients with polysyndactyly of the fifth toe fused with the fourth toe. The operation involved polydactyly excision, syndactyly release using an improved dorsal asymmetric gullwing flap for web space reconstruction without skin grafting, and simultaneous correction of valgus deformity and brachydactyly of the toes. The web shape (height and width),scar contracture, and aesthetic outcomes (foot contour and morphology of the reconstructed fifth toe) were assessed using the criterion of D'Arcangelo, Vancouver Scar Scale score, and older children and parent-based satisfactory questionnaire, respectively. RESULTS The patients were followed up for 12 to 36 months. The reconstructed web spaces were slightly deeper than normal, with an hourglass shape and a physiological slope. Valgus deformity was completely corrected without recurrence. The reconstructed fifth toes appeared to be visually lengthened. On the basis of the criterion of D'Arcangelo, the height and width of the webs were good in 76, fair in 10, and poor in none of the feet. The mean Vancouver Scar Scale score was 1.5. All parents and patients were satisfied with the appearance and function. CONCLUSIONS Our new operative procedure could achieve aesthetic and anatomic reconstruction of polysyndactyly of the fifth toe fused with the fourth toe with good shape of the reconstructed web space without skin grafting, favorable appearance and axis alignment of the reconstructed fifth toes, and good foot contour.

Abstract
Syndactyly is one of the most common congenital limb malformations, second only to polydactyly. Syndactyly is treated with surgical intervention. During separation, free skin grafting or skin flap transplantation is required to allow for adequate skin closure. We introduce a novel application method of the Pennig external fixation device for the management of pediatric syndactyly without skin grafting. The Pennig minifixator was used in syndactyly to expand the web space soft tissue in order to allow a Z-plasty to be performed in a second operation. All patients had developed sufficient skin tissue from the external fixation. No infection, cutaneous necrosis or nonunion was noted in any of the patients. All patients had a satisfactory outcome in terms of final appearance and digit function. On the basis of the principle of strain-stress, use of the Penning external minifixator allows development of sufficient tissue in the web space for a second phase of reconstruction in syndactyly. The need for skin grafting and risk of blood vessel damage were avoided in this study, and, the incidence of skin necrosis and scar formation was reduced. Both the patients' families and our research members expressed high satisfaction with the postoperative function and appearance. Overall, application of the Pennig external fixation frame in our novel method is effective for the management of syndactyly and should be studied further. Level of Evidence: Level IV, case series.

Abstract
Circumcisions are among the most commonly performed procedures in the pediatric population, but the value of the preputial skin often goes unrecognized as a potential graft (Ehrlichman et al., 2018). We highlight three patients who underwent coordinated circumcision and use of the excised preputial skin as a graft for syndactyly repair. Syndactyly, a condition where fingers are fused together, is often repaired utilizing skin from the groin region, which can result in unwanted hair growth and subcutaneous fat growth. The utilization of the prepuce is a convenient alternative that may have fewer undesirable qualities.

Abstract
Numerous techniques have been developed that use various flaps to treat syndactyly. Skin grafts have often been used to cover remaining surgical defects. The long-term aim of surgery is to find new methods of separating the digits without using skin grafts. This paper describes a new surgical technique for the correction of simple, incomplete, and complete syndactyly. The technique consists of a dorsal double-wing flap to cover the newly created web space and zigzag incisions in the fingers, thus avoiding the use of skin grafts in this space. Overall, 35 web spaces in 24 patients were treated using this technique. Patient follow-up ranged from 6 months to nearly 5 years. There were no complications such as hematoma, infection or flap necrosis, and no fingers needed skin grafts after separation. The average operative time for each web space was approximately 45 minutes. Ninety-seven percent of patients treated with the dorsal double-wing flap procedure achieved good function, and superior cosmetic results following a single surgery. The technique is simple, rapid, safe, and easily performed and does not require the use of skin grafts.

Abstract
Curry-Jones syndrome (CJS) is a pattern of malformation that includes craniosynostosis, pre-axial polysyndactyly, agenesis of the corpus callosum, cutaneous and gastrointestinal abnormalities. A recurrent, mosaic mutation of SMO (c.1234 C>T; p.Leu412Phe) causes CJS. This report describes the gastrointestinal and surgical findings in a baby with CJS who presented with abdominal obstruction and reviews the spectrum of gastrointestinal malformations in this rare disorder. A 41-week, 4,165 g, female presented with craniosynostosis, pre-axial polysyndactyly, and cutaneous findings consistent with a clinical diagnosis of CJS. The infant developed abdominal distension beginning on the second day of life. Surgical exploration revealed an intestinal malrotation for which she underwent a Ladd procedure. Multiple small nodules were found on the surface of the small and large bowel in addition to an apparent intestinal duplication that seemed to originate posterior to the pancreas. Histopathology of serosal nodules revealed bundles of smooth muscle with associated ganglion cells. Molecular analysis demonstrated the SMO c.1234 C>T mutation in varying amounts in affected skin (up to 35%) and intestinal hamartoma (26%). Gastrointestinal features including structural malformations, motility disorders, and upper GI bleeding are major causes of morbidity in CJS. Smooth muscle hamartomas are a recognized feature of children with CJS typically presenting with abdominal obstruction requiring surgical intervention. A somatic mutation in SMO likely accounts for the structural malformations and predisposition to form bowel hamartomas and myofibromas. The mutation burden in the involved tissues likely accounts for the variable manifestations.

Abstract
The dorsal rotational advancement flap described by Buck-Gramcko in 1998 is a good local flap for release of the thumb index web space. This paper describes a modification which broadens the apex of the flap and increases its length. This modification provides a long wide flap which releases the thumb index web space with suture lines far beyond the web. In addition, it provides a release of the palmar skin even when very tight in severe narrowing of the web. It is suitable for release of thumb–index syndactyly, severe narrowing of the web in thumb hypoplasia and congenital clasped thumb.
