Cosmetic reconstruction of distal finger absence with partial second toe transfer

Microsurgical reconstruction of the nail

Very often, post-traumatic defects involve multiple tissues. Microsurgical techniques can reconstruct them with tissues taken from a toe: from the nail complex alone to compound osteo-onychocutaneous flaps. Several techniques have been reported since the 1980s. This paper describes techniques and indications for microsurgical nail reconstruction. Technique differs according to the deficit, and first and foremost whether only the nail complex is involved or whether other components of the fingertip important for the normal growth of the nail, such as the phalanx bone or the finger pad, are also missing (toenail flaps and the custom-made osteo-onychocutaneous flaps). For most patients the absence of a fingernail is an esthetic rather than functional concern, and the outcomes of microsurgical reconstruction are far from ideal in this regard. We prefer to reserve reconstruction for symptomatic patients with functional impairment.

Repair of a finger pulp or fingertip defect using a palmar rotatory flap pedicled with the perforating branch of the proper palmar digital artery: a retrospective study

BACKGROUND

Soft tissue defects in the hand may result from trauma, oncological procedures, or severe infections. This study aimed to introduce an innovative method for repairing soft tissue defects on the palmar side of the distal segment of the affected finger or fingertip. We explored this surgical method and its curative effect on the volar rotation pedicled flap base on a perforator of the palmar digital artery (VRPF-PPDA) for repairing ventral or fingertip soft tissue defects of the distal segment of the affected finger without impairing its main blood vessels.

METHODS

Between June 2019 and January 2021, 13 patients with finger pulp or fingertip soft tissue defects were treated with VRPF-PPDA. Flap survival rate, complication rate, two-point discrimination (2PD), and patient satisfaction were used to evaluate the efficacy of this method. The function of the affected finger was evaluated using the upper limb function evaluation method issued by the Trial Standards for Evaluation of Partial Function of the Upper Extremity of the Chinese Society for Surgery of the Hand of the Chinese Medical Association (CMA) and the Disabilities of the Arm, Shoulder, and Head (DASH) score, 6-12 months after the flap-based operation.

RESULTS

Thirteen patients (18 fingers) achieved complete flap survival. The finger pulp flap was full, and no complications occurred. 2PD checks of the flaps revealed that all of them were 4-10 mm in length. According to the Trial Standards for Evaluation of Partial Function of the Upper Extremity of the Chinese Society for Surgery of the Hand of the CMA, hand function was excellent in 12 patients (17 fingers) and good in one patient, with a mean DASH score of 26.05 ± 0.45. Eleven patients selected "excellent" on the subjective satisfaction survey, while the other two selected "good."

CONCLUSION

VRPF-PPDA surgery is a simple, effective, minimally invasive, and reliable method for repairing soft tissue defects in the distal finger pulp or fingertips. Optimal esthetic reconstruction and anatomical and functional repair can be achieved in fingers repaired using the VRPF-PPDA surgical approach.

A hitchhiking approach to reconstruct the finger pulp and the subsequent 1st toe hemi-pulp donor site defect

BACKGROUND

The free 1st toe hemi-pulp transfer for finger pulp reconstruction was acknowledged as the optimal one. However, the treatment of the 1st toe donor defect, owning to the impossibility of primary closure, was frequently oversimplified. This study presented a "hitchhiking" approach to resurface finger pulp and the subsequent 1st toe donor site defect in a one-stage procedure.

METHODS

From 2014 to 2019, finger pulp amputations (13 digits in 12 patients) were reconstructed with free 1st toe pulp flaps, and the donor site was resurfaced by the 2nd toe pedicled flap with the 2nd toe's primary closure. Therapeutic evaluation of repaired fingers and toes was based on cold intolerance, two-point discrimination (2PD), and gait disturbance.

RESULTS

All finger and toe pulp flaps survived uneventfully. The average size of free 1st toe and pedicled 2nd toe flap was 3.1 cm × 2.0 cm (3.5 cm × 1.4 cm to 4.2 cm × 2.5 cm) and 3.0 cm × 1.1 cm (2.0 cm × 0.9 cm to 3.8 cm × 1.5 cm), respectively. The regained average static 2PD on the finger and 1st toe pulps was 6 mm (ranged 5-10 mm) and 4 mm (ranged 2-6 mm), respectively. All reconstructed 1st toe pulps were qualified for normal gait. One patient complained the mild cold intolerance, and hammer-toe deformities were involved in two cases.

CONCLUSION

To fulfill donor site care and cost-effective rule, the toe-to-finger pulp reconstruction can't underestimate the morbidity on 1st toe donor site due to inappropriate intervention. Equally importantly, the hitchhiking pedicled 2nd toe flap should be recruited in the reconstructive scheme.

Clinical effect of thumb finger reconstruction using dorsal foot flap transplant for treating thumb defects

It was found that conventional toe graft alone could not meet the patients' needs for wound repair, so we hypothesized that it would be more effective to treat thumb and finger defect by toe graft with dorsalis foot flap. This prospective study was conducted in 104 thumb defect patients to investigate the clinical effect of thumb reconstruction using toe graft with dorsal foot flap for the treatment of thumb defects. These patients were randomly divided into the dorsal foot group and the control group by randomized double-blind method, with 52 patients in each group. The second toe was used for thumb reconstruction transplant in both the groups. After thumb reconstruction, the abdominal pedicled flap was used to repair the surgical wound in the control group whereas the dorsal foot flap was used to repair the surgical wound in the dorsal foot group. Three months after surgery, the efficacy of surgical treatment, evaluation of two-point discrimination, postoperative complications, function of reconstructed thumb, operation time, and hospitalization time were recorded and compared between the two groups. MHOQ questionnaire was used to evaluate and compare the patients' satisfaction with finger reconstruction in both the groups. The surgical therapeutic effect, the function of the reconstructed thumb, and satisfaction with finger reconstruction were significantly higher in the dorsal foot group compared to the control group (all p < 0.05). The postoperative two-point discrimination, postoperative complication rate, operation time, and hospitalization time of patients in the dorsal foot group were significantly lower compared to the control group (all p < 0.05). Thumb finger reconstruction using the second toe transplant with dorsal foot flap had a beneficial effect on thumb defect patients. It can effectively improve finger function and sensory recovery of patients while reducing complications.

One-stage cosmetic finger reconstruction using a second toe island flap containing terminal branches of the toe artery

INTRODUCTION

A finger reconstructed by toe transfer may have morphological defects. We report the results of second toe transfer for 1-stage finger reconstruction with an island flap based on terminal branches of the toe artery.

HYPOTHESIS

The technique can improve the morphological outcomes of reconstructed fingers.

MATERIALS AND METHOD

Between January 2008 and June 2011, toe-to-finger transfer was performed for 36 fingers in 31 patients. An island flap containing terminal branches of the toe artery was embedded in the neck of the second toe to eliminate the morphological defect caused by stenosis in that area.

RESULTS

All reconstructed fingers and all flaps survived. No donor site complications occurred. The mean follow-up was 8 months (range, 5 to 25 months). The morphology of the reconstructed finger was close to that of a normal finger, and a natural transition could be observed in the finger pulp, the finger neck, and the junction between the toe and the finger. Sensory recovery of the finger pulp ranged from S1 to S3+. The mean pinch strength of the reconstructed fingers was 48% to 60% of that of the contralateral side. The mean DASH scores were 52.9, 48.9, and 46.0 for patients that had the index, third, and fourth fingers reconstructed, respectively, and the lowest mean aesthetic score was 70.

DISCUSSION

The method provides good aesthetic and functional outcomes, and overcomes aesthetic difficulties associated with other methods of toe transfer for finger reconstruction.

Toe-to-hand transfer: evolving indications and relevant outcomes

Toe-to-hand transfer is indicated for many types of congenital and traumatic thumb absences. This review will highlight the applications of toe-to-hand transfer and their functional, aesthetic, and psychosocial outcomes. Despite its technical complexity, toe to hand reconstruction techniques can provide an elegant option to restore function for patients with difficult hand disabilities.

Reconstruction of distally degloved fingers with a cross-finger flap and a composite-free flap from the dorsum of the second toe

PURPOSE

In this article, we report the reconstruction of degloved fingers using a combination of a cross-finger flap and a composite-free flap from the dorsal aspect of the second toe.

METHODS

From May 2006 until April 2009, we treated 18 degloved fingers in 18 patients (13 male and 5 female patients; mean age, 22 y) using the technique. There were 11 index and 7 ring fingers. The mean volar and dorsal defects were 2.5 × 1.9 cm and 2.7 × 2 cm, respectively. The cross-finger flaps ranged in size from 2.3 × 1.6 cm to 3.5 × 2.6 cm, with a mean of 2.8 × 2.3 cm. The flaps from the dorsal second toe ranged in size from 2.4 × 2.1 cm to 4.5 × 2.3 cm, with a mean of 3.0 × 2.2 cm. At follow-up, we assessed motion and sensation.

RESULTS

All cross-finger and free flaps survived. At final follow-up (mean, 17 mo; range, 14-25 mo), motion in the injured fingers averaged 102° and 28° at the proximal and distal interphalangeal joints, respectively. The mean static 2-point discrimination of the reconstructed finger pulps was 5 mm (range, 4-7 mm).

CONCLUSIONS

The combination of a cross-finger flap and a composite-free flap from the dorsum of the second toe is a useful and reliable technique for reconstruction of a degloved finger.

Thumb reconstruction with toe transfer

Microsurgical toe transfer has become a gold standard option for amputated thumb reconstruction. It can be used to correct almost any thumb defect. However, for optimal functional and esthetic results, proper initial care, preoperative planning, proper selection of suitable techniques, adjunct or secondary procedures and proper, postoperative rehabilitation are important.

Reconstruction of the distal finger with partial second toe transfers by means of an exteriorised pedicle

This study reports the outcome of a series of ten microsurgical fingertip reconstructions with partial toe transfers in which the vascular pedicle was exteriorised and subsequently excised after the transfer had become established. The aim of this technique was to provide better aesthetic and functional outcomes. The technique was successful and without complication in nine of the ten patients who had excellent functional and aesthetic outcomes. Arterial thrombosis resulted in partial necrosis of the fingertip in the other case.

Posttraumatic finger reconstruction with microsurgical transplantation of toes

This article outlines current methods of toe transplantation as applied to posttraumatic finger reconstruction (excluding the thumb). Key points that are important during the initial assessment and surgical treatment of such injuries are addressed. Reconstructive options for distal and proximal finger injuries, single and multiple finger injuries, and metacarpal hand injuries are presented, and the timing of toe transplantation procedures is discussed. Finally, additional concepts and techniques that, with experience, have proved useful for optimizing functional and esthetic results are highlighted, along with schemes for motor and sensory rehabilitation.
