“…27 In the literature, different surgical treatments for lateral and medial polydactyly are described. In 2021, Cheng et al 16 reported a case of bilateral postaxial polydactyly associated with hallux valgus in both feet in a 22-year-old woman with the removal of the medial toe. Oragui et al 21 described the case of a 17-year-old girl with an extrametatarsal head with a duplicated fusion of the proximal phalanx, and Han et al 18 reported a case of polydactyly of the fourth metatarsal treated by bone transfer of the extrametatarsal bone and subsequent fixation with an internal plate.…”

Background In the literature, there is no consensus regarding the surgical management of postaxial polydactyly, and few cases of polymetatarsia with polydactyly have been reported. Treatment of the complete deformity will prevent further foot and gait disorders. Objective To identify literature relevant to the operative management of Y-shaped metatarsal with biphalangeal sixth toe and related skin and wound care to improve surgical treatment protocols from a clinical experience perspective. Data Sources The authors searched several electronic databases in December 2022 for articles related to postaxial polysyndactyly in the feet and polymetatarsia. Databases searched included PubMed, SciELO, ScienceDirect, Cochrane Database of Systematic Reviews, and Google Scholar gray literature. Study Selection Two independent researchers conducted the searches and read the article titles and abstracts. Studies were included if they were narrative reviews, case studies, or observational studies; written in English or Spanish; and published between 2012 and 2022. Nonhuman studies were excluded. Studies that met the inclusion criteria were fully evaluated. Disagreements between reviewers were resolved by consensus, and when there was no consensus, a senior researcher was consulted. Data Extraction The following data were extracted from the included studies using a standardized form: author and year of publication, study type, number of participants, sex, polydactyly location, polymetatarsia, type of polydactyly, participants’ history of hereditary associated diseases or malformations, treatment, removal criteria, and timing of surgery. Data Synthesis Authors evaluated 11 studies of postaxial polydactyly that included a total of 153 participants (64 men, 89 women). They also document their clinical experience with a surgical technique used in cases of bilateral postaxial polydactyly of the foot with a Y-shaped metatarsal with biphalangeal sixth toe. Conclusions Surgical correction with lateral removal of the sixth toe is a resolutive treatment to improve the functionality of the foot, its aesthetic appearance, and the patient’s quality of life. Case-specific treatment should be applied and tailored to meet the individual needs. The biomechanics of gait and shoe problems in these patients improve with surgical treatment, without presenting secondary aesthetic problems in skin care.

“…Polydactylous hallux, a congenital anomaly characterized by the presence of supernumerary digits on the foot, present in various forms [17]. Hallux polydactyly involves the presence of extra toes adjacent to or at the tip of the big toe [18]. Non-hallux polydactyly, on the other hand, encompasses extra digits on toes other than the big toe, which could include additional second, third, fourth, or fifth toes, or even extra connecting tissue between these toes [19].…”

Background:Congenital hypoplasia of the thumb type IV, also known as floating thumb, is a condition in which 2 small phalanges are attached to the hand with a thin skin bridge. Surgical management options for this condition vary from amputation to flap reconstruction. Material/Methods:This retrospective study analyzed 11 infants with congenital hypoplasia of the thumb type IV who underwent surgical reconstruction using a modified vascularized polydactylous hallux flap. The study included 6 male and 5 female infants, aged 6 to 24 months. Functional evaluations and radiographic studies were conducted postoperatively. Results:All 11 patients underwent the complete surgical protocol. Successful vascular and nerve anastomoses were performed during the initial procedure, ensuring sufficient blood supply and neural connectivity to the transferred toes. The second operation showed promising outcomes, including improvements in thumb opposition, grasp strength, and overall function. Postoperative assessments demonstrated satisfactory radiographic alignment and no major complications during the follow-up period. Conclusions:The modified vascularized polydactylous hallux flap reconstruction is a viable surgical option for managing congenital hypoplasia of the thumb type IV in infants. This technique effectively restores thumb opposition, grasp strength, and overall hand function, with satisfactory radiographic alignment and minimal complications.The study findings support the efficacy and safety of this surgical approach in addressing this rare congenital anomaly.
