Clinical Evaluation of Reconstruction of Thumb Defect with First Dorsal Metacarpal Artery Flap.
IOSR Journals , 2019
Thumb defects are not so uncommon. Causes include burn and traumatic injuries. Reconstruction of these defects require sensate flap. First dorsal metacarpal artery flap is very good option for pulp defect of the thumb. Our study was done over a period of 1 year and involved 8 cases of thumb pulp defects treated at our institution. The flap size ranged from 2 × 1.5 cm to 4 × 3 cm. We had only one complication in the form of partial flap necrosis, which fortunately healed following debridement without the need for a secondary procedure. All our cases were done under brachial block or local anesthesia with tourniquet control. All the patients had satisfactory outcome with minimal or no donor site morbidity.

Amputation at the proximal phalanx or at the metacarpophalangeal joint can be treated by pollicization of a finger, osteoplastic reconstruction, free microvascular transfer of a toe, or distraction lengthening. The best technique to use to treat these cases depends on the place of amputation and the patient's age, sex, occupation and functional demands. In the past 6 years, we treated 4 patients by lengthening the thumb metacarpal ray and adding a mini wraparound flap from the great toe. All the subjects were female with an average age of 22 years. All 4 patients had sustained traumatic amputations: 2 at the metacarpophalangeal joint and 2 at the base of the proximal phalanx. Distraction was completed approximately 65 days after osteotomy, obtaining an average lengthening of 23 mm. To achieve bone consolidation, the lengthener was left in place for 127 days on average. Microsurgical thumb reconstruction was performed around 3 months after consolidation of the osteotomy. There were no failures or cases of postoperative vascular compromise. The average pinch power was 66% of the opposite hand. The static 2-point discrimination of the reconstructed thumb was 8 mm (range, 7-10 mm). All patients reported being satisfied with the treatment, although 1 patient was partially dissatisfied due to the prolonged length of the treatment. Donor site morbidity was minimal. This procedure is mainly chosen by selected patients who refuse standard microsurgical thumb reconstruction because it requires a longer treatment period

Finger injuries to the hand with extensive soft tissue defects might be challenging to treat. Typically, the first dorsal metacarpal artery (DMA) flap is used for reconstruction, whereas closure of the donor site is routinely performed with a split-thickness skin graft. The aim of the current study is to present a surgical technique that reports a modified incision, which allows elevation of the first DMA flap for the management of the soft tissue defects of the thumb without requiring a skin graft for coverage of the donor site. A 65-year-old man presented to the emergency department with a crush injury to the thumb. The patient had an extensive skin defect on the dorsal side of the thumb extending circumferentially to the ipsilateral thenar without tendon damages, whereas sensation of the finger was found intact. Surgical intervention was performed within six hours and involved DMA flap transfer through a modified skin incision, which allowed coverage of the donor defect in the in...

Various surgical techniques contribute to repair distal defects of the fingers, especially thumb as traumatic loss, diminishes or eliminates the thumb prehensile abilities and may affect overall hand function. The goal of reconstruction should be maximum restoration of hand function. Being the only opposing digit against the others, when thumb is involved, functional loss maybe more severe than anticipated. Because of its major contribution to overall hand function, correction of deformities involving the thumb is crucial. Adequate length, mobility, stability and sensation are the goals of a functional thumb reconstruction. It appears that the FD-MCA flap is one of the best solutions for cover of simple or complex skin loss of the thumb. Its technical performance is easy, and it gives durable, sensate and stable skin cover.
Utility of First Dorsal Metacarpal Artery Flap for Thumb Defects
Indian Journal of Plastic Surgery
Background Reconstruction of thumb tip, while providing a durable and sensate flap, is a challenging task. It is important as thumb accounts for 50% of hand functions. Options for coverage are: healing by secondary intention, local/regional flaps, microsurgical toe wraparound flap, etc. First dorsal metacarpal artery (FDMA) flap is one regional flap that has been used for thumb cover, usually for defects till interphalangeal joint or just distal to it. We present our case series for FDMA flap and its variations for thumb reconstruction. We also report reverse FDMA flap cover for reconstruction of defects over distal phalanx of thumb. Methods The procedure was performed in patients with partial loss of thumb soft tissue in 16 patients presenting during 2017 to 2020. The FDMA flap was performed according to the standard technique. In case after “planning in reverse,” it was seen that the reach of FDMA flap was insufficient, reverse FDMA flap was done. Physiotherapy for index finger an...
First dorsal metacarpal artery flap for thumb reconstruction: a retrospective clinical study
Strategies in trauma and limb reconstruction (Online), 2009
Extensive pulp (zone 4) defects of the thumb, with the exposure of tendon or bone, are challenging reconstructive problems. Surgical treatment includes the use of local, regional, and free flaps. The first dorsal metacarpal artery flap has been used successfully for defects of the thumb. The innerved first dorsal metacarpal artery flap from the dorsum of the index finger was first described by Hilgenfeldt and refined by Holevich. An island flap carried on a neurovascular pedicle consisting of the first dorsal metacarpal artery was first demonstrated by Foucher and Braun. Seven innervated FDMCA island flaps were performed from May 2005 until July 2007 for thumb reconstruction. There were three women and four men with an average age of 54.9 years (range 28-89 years). The mean follow-up period was 15.4 months (range 4-29 months). The dominant hand was involved in six (85.7%) patients. In a retrospective clinical study, the following criteria were evaluated: (1) etiology of the defect, ...

Thumb amputation at the carpometacarpal level is very incapacitating. Pollicization may be considered. We describe an alternate technique for thumb reconstruction at the level of the metacarpal base using a trimmed great toe along with a vascularized second metatarsophalangeal joint, including the second metatarsal, all supplied on a single vascular pedicle. Two patients who had a combined soft tissue defect and amputation of the thumb close to the carpometacarpal joint were reconstructed with this method. A transposition of the second toe was performed on top of the remaining proximal phalanx of the great toe to decrease donor site morbidity. This technique provides adequate length to the thumb without compromising another finger by creating a new thumb using a double microsurgical toe transfer on a single vascular pedicle. We minimize donor site morbidity by transposing the second toe onto the great toe.
Immediate reconstruction of a nonreplantable thumb amputation by great toe transfer
Plastic and reconstructive surgery, 2009
When replantation of an avulsed/amputated thumb is not feasible, toe-to-hand transfer may be considered as a reconstructive option in appropriately chosen patients. Although selection criteria are purposefully restrictive, immediate one-stage transfer, as opposed to a delayed procedure, provides many advantages. Primary reconstruction reduces hospitalization and operative and recovery time. It also may expedite return of function and allow patients to return to work sooner. The ability of the patient to undergo extensive microvascular reconstruction at the time of injury, the psychological preparation required, and the need to understand potential risks are important factors to consider.
Evaluation of versatility and outcomes of the first dorsal metacarpal artery flap in thumb defects
Ulusal Travma Acil Cerrahi Dergisi, 2023
It is clinically vital to determine the best technique to reconstruct thumb defects with satisfactory esthetic and functional outcomes. We aimed to quantitatively present the safety, versatility, limitations, advantages, and functional results of the first dorsal metacarpal artery flap (FDMAF) and evaluate its outcomes in thumb defect reconstruction by comparing it with the other current surgical options. METHODS: A total of 21 patients underwent thumb defect reconstruction. They were evaluated with the following parameters: Etiology, age, timing of reconstruction, flap vitality, Semmes-Weinstein monofilament (SWM) test, static two-point discrimination (2PD) test, pain, cortical reorientation, cold intolerance questionnaire, and Michigan hand outcomes questionnaire. Their functional outcomes were evaluated by comparing their scores with the other current surgical options published in the literature. RESULTS: The mean follow-up period was 22.3 months. The mean pain score of the flap was 0.4±0.6 and no patient had pain in the donor area (range, 0-10). The sensory outcome was "good" (8.6 mm) based on the static 2PD test. The mean SWM test score was 4.02 g. Patient satisfaction was 4.6 according to the Michigan hand outcomes questionnaire (range, 0-5). The cold intolerance questionnaire scores showed that the patients had mild cold intolerance (mean, 10.5; range 0-100). Complete cortical reorientation was seen in 81% of the patients. CONCLUSION: Restoration of the innervation of thumb defects is possible with the FDMAF with high satisfaction rates based on our results. The absence of the microsurgical vessel or nerve repair facilitates the surgery, shortens its duration, and reduces morbidity, reserving the microsurgical options for more complicated cases. Therefore, it can be concluded that the FDMAF is an effective flap with great modifications for complicated thumb defects but surgeons should consider their clinical outcomes and prolonged surgery when choosing which technique to be used.
