A Simple Alternative Treatment for Syndactyly of the Toe

Plantar intermetatarsal perforator flap for first web skin-graftless syndactyly release: Anatomical study and clinical application

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.

Applications of Medical Tattooing: A Systematic Review of Patient Satisfaction Outcomes and Emerging Trends

BACKGROUND

Medical tattooing is often applied in the context of plastic, aesthetic, and reconstructive surgery to help achieve the best cosmetic outcome.

OBJECTIVES

This article reviews various conditions that medical tattooing has been empirically studied in terms of patient satisfaction outcomes, makes practice recommendations, and suggests future directions for research.

METHODS

This review was performed following the PRISMA guidelines. Studies were included if the tattooing application was associated with a medical condition and if outcome data were provided using at least a case series methodology. Where no cohort or clinical series exist, case examples are used from the literature and the author's practice to illustrate emerging medical tattooing applications that need further evaluation.

RESULTS

Eighteen studies met the inclusion criteria and addressed the following conditions: baldness, vitiligo, scars from incisions, lacerations or burns, and nipple-areola complex reconstruction.

CONCLUSIONS

The application of medical tattooing has shown high levels of patient satisfaction across conditions. The practice recommendation grade is "B" or recommend since the level of evidence for these interventions ranged from III to IV according to the American Society of Plastic Surgeons guidelines. This means clinicians can consider this treatment alternative, but they should be alert to new information and be sensitive to patient preferences. Recommendations are made for reporting future research including clearly describing procedural details, identifying the professional performing the procedure, increased use of standardized outcome measures, and that satisfaction ratings be assessed by someone independent of the health service provider. Further research using randomized controlled trial methodology with waitlist controls is needed.

Anatomical Differences Between Foot and Hand Web Space Reconstruction

The differences in the anatomy of the foot and the hand may affect the dorsal flap design for web space reconstruction. In this study, the authors aimed to identify the differences in web space anatomy of the foot and the hand and provide a guideline of flap design for web space reconstruction in the foot and the hand. The right hands and right feet of adult volunteers were measured, including surgical landmarks (i.e., the dorsal prominence of proximal interphalangeal and metacarpophalangeal joints [or metatarsophalangeal joints]), proximal phalangeal length, tip of the web space, and width of web space. The web spaces and other parameters were analyzed and compared between the foot and the hand by using a paired t test with p < .05 to indicate statistical significance. A total of 108 web spaces of the foot and hand from 18 adult volunteers were analyzed. The parameters that were significantly different between the foot and the hand included (1) proximal phalangeal length (34.63 vs 60.16 mm), (2) average web height ratio (0.72 vs 0.51), (3) average web width ratio (0.69 vs 0.81), (4) mean slope angle (4.89° vs 19.26°), and (5) average abduction angle (25.33° vs 31.07°). In conclusion, the foot web space had a higher slope angle, less abduction angle, and shorter proximal phalangeal length. Therefore, the flap design for foot web space reconstruction requires a longer and narrower flap than the design for the hand. The recommended flap design length should be at least 72% of proximal phalangeal length for the foot versus 51% for the hand, and the width should be at least 69% of the distance between the tips of adjacent metatarsophalangeal joints for the foot versus 81% for the hand.
