PURPOSE: We describe a homodigital neurovascular island flap for reconstructing large pulp defects of the fingertips and review the short-term and long-term appearance and function of the reconstructed fingertips. METHODS: The spiral flap is a homodigital neurovascular island flap with a unique spiral advancement and transposition design that allows pulp reconstruction using sensate glabrous skin while restricting donor morbidity to the injured digit. Thirty-two fingertips were resurfaced using this flap. All had large pulp defects averaging 1.2 cm wide x 2.0 cm long (1.0-2.0 cm x 1.5-2.5 cm). Short-term results (<18 months) for all patients at a minimum of 6 months and long-term results (>5 years) for 10 patients with a mean follow-up of 13 years were reviewed. Objective outcome measures included static 2-point discrimination, degree of nail deformity (beaking), total active motion, and hypersensitivity or cold intolerance. Subjective outcome measures included patient satisfaction with function and aesthetics, using a visual analog scale. RESULTS: All flaps achieved primary healing with no complications. There was initially mild extension deficit in the proximal interphalangeal and distal interphalangeal joints, which improved to full range of motion in the long term. Sensory recovery was excellent, with an average 2-point discrimination of 5 mm initially, improving to 4 mm in the long term. Nail beaking was minimal initially but increased significantly in the long term. These results may be explained by soft tissue remodeling. All patients on long-term follow-up were highly satisfied with both aesthetic and functional outcome. There was no hypersensitivity or cold intolerance at either the short-term or long-term follow-up assessments. CONCLUSIONS: The spiral advancement-transposition flap is suitable for resurfacing large pulp defects with excellent short-term and long-term functional and aesthetic results and high patient satisfaction. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV. 相似文献

Volar-oblique injuries of the thumb pulp are particularly disabling. Many methods have been described to treat these injuries and provide return of sensibility. The conventional cross finger flap is an established technique and is well suited for intermediate-sized partial pulp losses. We review our experience with this flap and describe technical refinements that have contributed to improved early outcome and long-term neurosensory recovery. Thirty patients underwent 31 cross finger flaps to the thumb for volar-oblique pulp defects. Defect sizes ranged from 1.5 to 5 cm in length and 1.5 to 3 cm in width. Dorsal skin of the index finger proximal phalanx was used in 26 patients, index finger middle phalanx in 2 patients, and long finger middle phalanx in 3 patients. Nine patients were available for long-term follow-up and were subjected to functional assessment (DASH questionnaire), sensitivity testing (2-point discrimination, Semmes-Weinstein monofilament testing), and range of motion evaluation. Thirty of 31 flaps survived. In 1 patient, trauma to the attached flap from the long finger middle phalanx resulted in flap ischemia. This was revised with a fresh cross finger flap from the index finger proximal phalanx. Employed patients were able to return to their original jobs. Recalled patients (n = 9) were assessed at a mean of 29 months after surgery (range, 12-70 months). All recalled patients regained normal sensibility on 2-point discrimination testing. Functional outcome was satisfactory in 8 patients (DASH score, 0-20). The last patient (DASH score, 61.67) complained of hypersensitivity and cold intolerance that affected his work. The conventional cross finger flap provides reliable coverage for volar-oblique hemipulp losses of the thumb, with patients regaining at least protective sensibility in the long term. The proximal and middle phalanges of both the index and long fingers may serve as donor sites, allowing the surgeon to best select skin cover based on defect size and options in finger positioning. 相似文献

BACKGROUND: Because plantar anatomic features are similar to those of the palmar surface of the finger, palmar surface finger reconstruction using a medial plantar venous flap enables grasping without slippage, results in strength that can withstand friction, and provides a cushioning effect. Furthermore, sensory restoration is thought to be excellent due to the similarity of the tissues. METHODS: We performed finger palmar surface reconstruction in 6 patients using venous flap without harvesting the medial plantar subcutaneous nerve branch and assessed the sensory restoration using a static 2-point discrimination test (s-2PD), moving 2-point discrimination test (m-2PD), and Semmes-Weinstein test (S-W test). RESULTS: The mean s-2PD at 12 months after surgery was 8.6 mm, the mean m-2PD was 6.00 mm, and the S-W test score was 3.84-3.22 CONCLUSION: These findings indicate that sensory improvement can be obtained by finger palmar surface reconstruction without grafting of the medial plantar subcutaneous nerve branch to the digital nerve. 相似文献

Aims of the Study: Fingertip injuries can be treated in different ways, including shortening with primary closure, skin graft, and local or distant flaps. Several local flaps for the reconstruction of the amputated fingertip were described. We present our experience with a new concept of homodigital adipofascial reverse flap that avoids the second surgical stage and allows a complete and anatomically perfect reconstruction of nail bed, with preservation of the nail lamina. Materials and Methods: Between March 2014 and February 2015, five patients with digital amputations (distally to the nail matrix) were treated using the Fenestrated Adipofascial Reverse (F.A.R.) flap. The patients were evaluated measuring 2-point discrimination (2PD) value and range of motion of the distal interphalangeal joint (DIP). Scar evaluation was performed using the Vancouver Scar Scale (VSS). Results: All the flaps completely survived. A normal nail grow has been observed in first two-three months of post operatory follow-up. Length of the digits was preserved and good aesthetic as functional outcome were archive. The F.A.R. flap provided excellent coverage of fingertip defects and preserved finger length. After 1 year of follow, the mean static 2PD value at the reconstructed finger was 4.2 mm (range 3-5 mm), reconstructed fingers' mean range of motion for the DIP joint was 78 degrees and the VSS score ranged from 0 to 2 (mean score: 0.6). No complications were reported. Conclusions: F.A.R. flap is one of the most useful techniques in order to achieve all the goals in fingertip reconstruction. 相似文献

Objective
Composite tissue loss involving the distal finger pulp and the nail is a common but challenging finger injury to restore. This study introduces a reconstruction procedure for a distal finger pulp and nail defect using a partial toenail flap transfer.Methods
Twenty digits, including 16 thumbs, two index fingers, and two middle fingers, with composite soft tissue defects were treated with a partial toenail flap transfer from October 2015 to January 2020. Shortening revision of the great toe phalanx, a V-Y advancement flap of the toe pulp, and a local pedicle flap from a second toe transfer were used to cover the donor sites, and no skin grafts were required. Functionality was evaluated using the validated Spanish version of the Quick-DASH scale. The aesthetics of both the reconstructed and donor sites were evaluated using the Vancouver Scar Scale (VSS). The static two-point discrimination (2-PD) of the finger pulp was used as a measure of tactile agnosia.Results
All donor site wounds healed well. The average follow-up time was 23.6 months (6–39 months). The mean Quick-DASH functional score was 7.1. The VSS scores were 4.02 ± 0.29 and 4.00 ± 0.38 for the reconstructed and donor sites, respectively. The static 2-PD of finger pulp was 4.5 ± 0.76 mm. The patients were satisfied with finger motion, sensory function, and aesthetic contour.Conclusions
Partial toenail flap transfer is the recommended treatment to regain motion, sensation, function, and a satisfactory aesthetic appearance when considering repairing a composite soft tissue distal finger defect with accompanying loss of the perionychium, particularly in the thumb, index finger, or middle finger. 相似文献12.

Finger pulp loss is often observed in daily practice. When the lateral and dorsal surfaces of the injured digit remain intact, a neurovascular island flap can be designed and raised from that part of the finger for pulp reconstruction. Two types of homodigital lateral-dorsal neurovascular island flaps were used in 17 patients (13 type I and 4 type II) for reconstruction of traumatic pulp loss on an emergent basis. The type I flap was used for the pulp defect less than 2.5 cm in length; the type II flap was designed for extensive pulp loss. The size of the pulp defect varied from 1.7 x 1.2 cm to 3.8 x 1.7 cm. All flaps survived completely without any partial loss. The mean follow-up was 17.7 months. The mean static two-point discrimination was 5.2 mm in type I flaps and 9.3 mm in type II flaps. All patients except five had full range of motion of the interphalangeal joint. These five patients (3 type I and 2 type II) had 10 to 20 deg reduction in flexion of the distal interphalangeal joints. The homodigital lateral-dorsal neurovascular island flap offers a durable, well-vascularized, sensate skin flap for one-stage pulp reconstruction in select patients. This technique is relatively simple, allows early postoperative mobilization, and has an acceptable surgical outcome. 相似文献

Restoration of thumb sensibility with the innervated first dorsal metacarpal artery island flap 总被引:5,自引:0,他引:5
PURPOSE: This study investigated the quality of sensibility from innervated first dorsal metacarpal artery (FDMCA) island flaps in younger and older patients and evaluated the donor site morbidity at the index finger. METHODS: Twenty-five patients with an innervated FDMCA island flap to restore sensibility of the thumb were divided into groups according to age (>50 or <50 years). Sensory recovery and cortical reorientation were tested with Semmes-Weinstein monofilaments, a calibrated 2-point discrimination tester, and needle prick testing. Donor site morbidity was evaluated for range of motion, aesthetic appearance, pain, and problems with injuries. RESULTS: The mean age of the patients was 48.3 years and the mean follow-up period was 3 years. The 14 patients older than 50 years had a static 2-point discrimination (s2-PD) of 10.9 mm compared with 10.8 mm of the 11 patients younger than 50 years. The average loss of s2-PD of the flap compared with the donor area averaged 2.7 mm in all patients. Complete cortical reorientation occurred in 7 patients older than 50 years and in 5 patients younger than 50 years. Total loss of range of motion of all donor finger joints was 14 degrees (4.4%) compared with the contralateral index finger. Twenty-two patients were satisfied with the result. CONCLUSIONS: There were no age-related differences in the surgical results of the innervated FDMCA island flap and the donor site morbidity was negligible. 相似文献

Fingertip or pulp loss of the fingers is observed frequently in unskilled workers. To reconstruct a sensate fingertip or pulp we designed the innervated reverse island flap based on the end dorsal branch of the digital artery, which was harvested from the dorsum of the middle phalanx. The sensation of the fingertip or pulp was re-established through coaptation of the proper branches of the digital dorsal nerves to the digital nerves. Three fingertip or pulp defects were reconstructed with this technique. All patients achieved satisfactory functional and cosmetic results. The mean follow-up time was 7.7 months. The average size of the flaps was 1.6 x 1.8 cm. The average static 2-point discrimination and moving 2-point discrimination of the flaps were 4.6 mm and 3.0 mm, respectively. The technique we applied seems to be an excellent option for 1-stage reconstruction of fingertip or pulp defects. 相似文献

Background:Fingertip injury requiring flap cover is very common in the modern era. The ideal cover should fulfill both functional and aesthetic improvement.Results:Five flaps survived completely, one suffered partial loss, and one flap failed completely. The median follow-up period was 9 months. The median duration of surgery was 255 min (range 210 to 300 min). The median two-point discrimination was 6.5 mm (range 4–8 mm). There was the return of temperature sensation in all patients; two had cold intolerance. The Semmes-Weinstein monofilament score varied from 3.61 to 5.07 (median filament index value 4.31/pressure value of 2 g/mm2). Three patients had delayed donor site wound healing.Conclusions:The free toe pulp flap is an efficient choice for fingertip and volar finger defects reconstruction with an excellent tissue match.KEY WORDS: Finger defect, free toe pulp flap, pulp defect, reconstruction, volar defect 相似文献
