Objective?To investigate the surgical methods and clinical results of repairing soft tissue defects in the thumb with distally-based dorsal thumb neurocutaneous vascular flap.?Methods?From January 2006 to October 2007, 23 patients with soft tissue defect in the thumb were treated, including 20 males and 3 females aged 19-46 years old (average 27.5 years old). The defect was caused by crush injury in 1 case, electric planer accident in 6 cases, incised injury in 8 cases, and avulsion injury in 8 cases. The defect was located on the palmar aspect of the thumb distal phalanx in 3 cases, the dorsal-radial aspect of the thumb distal phalanx in 3 cases, and ulnar or dorsal aspect in 17 cases. The defect size ranged from 3.3 cm × 1.2 cm to 4.2 cm × 1.2 cm. Among them, 18 cases were complicated with distal 1/2 nail bed defect or injury. The time between injury and hospital admission was 1- 72 hours (average 22 hours). During operation, the defect was repaired with distally-based dorsal-radial neurovenocutaneous vascular flap of the thumb in 3 cases and distally-based dorsal-ulnar neurovenocutaneous vascular flap of the thumb in 20 cases. The size of those flaps was 4.0 cm × 1.6 cm-5.0 cm × 3.0 cm. The donor site underwent direct suture or split thickness skin graft repair.?Results?At 10 days after operation, 3 cases suffered from the epidermal necrosis in the distal part of the flap, 2 of them experienced the exfoliation of dark scab 14 days later and the flap survived, and the flap of the rest one survived after dressing change. The other flaps and the skin graft at the donor site all survived uneventfully. The wounds healed by first intention. All the patients were followed up for 10-16 months (average 12.6 months). The flaps were soft in texture and full in appearance. The two-point discrimination value 6 months after operation was 8-10 mm. At 12 months after operation, the growth of the residual fingernail was evident in 18 cases, including 4 cases of curved or hook fingernail. Active flexion and extension of the thumb were normal. The abduction of the first web space reached or surpassed 80 percent of the normal side in 20 cases and was below 80 percent of the normal side in 3 cases. The clinical outcomes were satisfactory in 11 cases, approximately satisfactory in 8 cases, and unsatisfactory in 4 cases according to self-designed evaluation system.?Conclusion?The operative method of repairing the soft tissue defects in the thumb with the distally-based dorsal thumb neurocutaneous vascular flap is simple, stable in anatomy, in line with the principle of proximity, and suitable for repairing thumb tip defect 3 cm in size. It can bring a good postoperative appearance of the thumb and little influence on the hand function.
Two hundred and twenty-two toes to hands free transfers have been performed in our clinic from January 1973 to May 1992 with a 100 percent successful results obtained. The authors developed the extended toe free transfer technique,and this technique was used in 40 cases.Six types of extended toe transfer can be designed to carry out complicated thumb or other finger reconstructions.Keys to successful toe-to-hand transfers are as followings: Evaluation of a three-points and one line pulsation on the donor foot can be used to localize the course of the first dorsal metatarsal artery . The first dorsal metaltarsal artery is best dissected and exposed in the retrograde direction. The toe must obtain good blood perfusion before its transplantation and close postoperative monitor.
The simple ablation of the duplicated thumb might have some residual deformities after operation that often leads to functional disorders of the hand. Since 1988, the postoperative disorders in 9 patients were treated. The plastic surgery was performed for the adduction of the thumb, lateral deviation and insufficient after plastic repair of the hand. The configuration and the function of the thumb were satisfactory.
ObjectiveTo explore the effectiveness of one-stage metacarpal osteotomy, thumb opponensplasty and polygonal flap reconstruction in the treatment of congenital spade hand deformity. MethodsEight cases of congenital spade hand were treated between January 2013 and March 2017. There were 5 males and 3 females, with an average age of 17.5 months (range, 13-35 months). The clinical manifestations of all the children were congenital spade hand and the affected hand was shorter than the healthy side. The contralateral hand was normal and there was no chest, skull, or facial deformity. The operation was performed with metacarpal osteotomy and thumb opponensplasty, and through the dorsal metacarpal rectangular flap to reconstruct the first web and through rotation of polygonal skin flap to reconstruct thumb web and lateral fold of thumb index nail. The dorsal ulnar and proximal radial segment of thumb were repaired by skin grafting. A vernier caliper was used to measure the first web space and the thumb function was evaluated by modified Tada score. ResultsThe reconstruction of palmar function and the formation of first web were completed in one stage in 8 children. Skin grafting on the dorsal ulnar side of thumb and radial side of index finger survived after operation. All the children were followed up 13-29 months, with an average of 16.1 months. There was no infection, skin flap necrosis, lateral deviation of thumb, scar contracture, or other complications. At last follow-up, there was no significant difference in skin color between the healthy side and the first web of the affected hand. The opening distance of first web space was 3.5-5.0 cm, with an average of 4.2 cm. According to the modified Tada scoring system, the results were excellent in 7 cases and good in 1 case, with an excellent and good rate of 100%. The thumb could grasp and pinch actively, and the palm opposition function was good. ConclusionOne-stage thumb opponensplasty combined with polygonal flap for reconstruction of congenital spade hand deformity can improve hand function very well. The reasonable designing of skin flap can effectively cover important areas, and the operation is safe and reliable.
ObjectiveTo study the effectiveness of surgical treatment of congenital type V thumb syndactyly. MethodsBetween March 2010 and May 2015, 12 cases of congenital type V thumb syndactyly were treated. There were 7 males and 5 females, aged from 1 to 25 years (mean, 8 years). The right thumb was involved in 8 cases, and the left thumb in 4 cases. There were 2 cases of radial type, and 10 cases of ulnar type. The basement of polydactylism was far away from the carpometacarpal joint in 7 cases, and was close to the carpometacarpal joint in 5 cases (slight ulnar deviation in 1 case). X-ray films showed that the main first thumb metacarpal bone and trapezium fitted well, and 2 cases had the first metacarpal bone deformity. Preoperative individualized treatment plan was made, and polydactylism was excised by the "S" or "Z" incision and simultaneous reconstruction of thenar muscle insertions or adductor muscle insertions was performed; if necessary, wedge osteotomy was used for correction. ResultsAll incisions healed by first intention with no complication. All cases were followed up 6 to 24 months (mean, 12 months). The thumb appearance, flexion and extension, the function of opposition, abduction function were improved significantly in 11 cases with no scar contracture deformity, small first web space, and deviation deformity. One case had slightly narrow first web space. According to hand function criterion, the results were excellent in 10 cases, good in 1 case, poor in 1 case; excellent and good rate was 91.7%. ConclusionBased on the condition of the type V thumb syndactyly, the individualized treatment plan is made, which can better restore the shape and function of the thumb.

ObjectiveTo evaluate the effectiveness of the upper limb free flap for repair of severe contracture of thumb web, and one stage reconstruction of the index finger abduction. MethodsBetween March 2007 and June 2011, 16 cases of severe contracture of thumb web and index finger abduction dysfunction were treated. There were 14 males and 2 females with an average age of 29 years (range, 16-42 years). All injuries were caused by machine crush. The time between injury and admission was 6-24 months (mean, 10 months). The angle of thumb web was 10-25° (mean, 20°), and the width of thumb web was 15-24 mm (mean, 22 mm). After scar relax of the thumb web, the defect size ranged from 6 cm × 4 cm to 8 cm × 6 cm; the upper limb free flap from 7 cm × 5 cm to 9 cm × 7 cm was used to repair the defect, index finger abduction was simultaneously reconstructed by extensor indicis proprius tendon transfer. The donor site was repaired with skin grafting. ResultsAll the flaps and skin graftings survived after operation and incisions healed by first intention. Fourteen patients were followed up 6-12 months (mean, 9 months). The flap appearance was satisfactory. The two-point discrimination was 6-9 mm (mean, 7 mm) after 6 months. The angle of thumb web was 85-90° (mean, 88°). The width of thumb web was 34-52 mm (mean, 40 mm). The abduction and opposing functions of thumb and abduction function of index finger were both recovered. Conclusion A combination of the upper limb free flap for severe contracture of thumb web and one stage reconstruction of the index finger abduction for index finger abduction dysfunction can achieve good results in function and appearance.
ObjectiveTo explore the effectiveness of anterograde fascial flap of digital artery in reconstruction of Wassel Ⅳ-D thumb duplication.MethodsTwelve cases of Wassel Ⅳ-D thumb duplication were treated with anterograde fascial flap of digital artery between June 2014 and March 2017. There were 7 boys and 5 girls with an age of 9-32 months (mean, 13.3 months). Eight cases were on the left side and 4 cases on the right side. The main bunion bed width was 70%-85% of the healthy side (mean, 75.3%). The degree of fullness was 50%-75% of the healthy side (mean, 62.4%). The anterograde fascial flap with one proper digital artery was used to fill the nail fold on the radial side of the finger and increase the circumference of the finger. At last follow-up, the ratio of circumference of deformed finger to contralateral finger was measured at the base of nail. The appearance and function of all reconstructed thumbs were evaluated with Japanese Society for Surgery of the Hand (JSSH) scoring.ResultsAll the operations were successfully completed without early complications such as infection and skin necrosis. All children were followed up 7-27 months (mean, 14.3 months). At last follow-up, there was no recurrence of deformity in the digital body and no obvious change of scar contracture in the surgical wound. Pulp and nail fold symmetry improved in all cases. The ratio of circumference of deformed finger to contralateral finger was 93%-96% (mean, 94.7%). The JSSH score was 15-20 (mean, 17.9); the results were excellent in 8 cases, good in 2 cases, and fair in 2 cases.ConclusionThe anterograde fascial flap of digital artery is a safe and effective approach to restore symmetry for esthetic improvement in treatment of Wassel Ⅳ-D thumb duplication.
Objective To summarize the effectiveness of radial dorsal fasciocutaneous flap of thumb for repairing severe nail bed defects. Methods Between May 2009 and January 2012, 16 patients with severe nail bed defect were treated with radial dorsal fasciocutaneous flap of the thumb. There were 10 males and 6 females, aged 16-54 years (mean, 36 years). The causes of injury included crush injury in 10 cases, chainsaw injury in 4 cases, and scald in 2 cases; injured fingers were thumb in 3 cases, index finger in 4 cases, middle finger in 5 cases, ring finger in 3 cases, and little finger in 1 case. The time between injury and operation was 2 hours to 8 days (mean, 19.3 hours). Of 16 patients, 9 complicated by distal phalanx fracture. The area of defect ranged from 0.9 cm × 0.6 cm to 2.3 cm × 2.1 cm. According to ZHOU Qingwen’s grading system for nail bed defects, 6 cases were rated as degree III and 10 cases as degree IV. The area of flap ranged from 1.0 cm × 0.6 cm to 2.5 cm × 2.2 cm. Retrograde transposition was performed to repair the thumb defect, and pedicled transposition to repair the 2nd-5th fingers defects. The donor sites were directly sutured or were repaired with skin graft. Results All flaps and skin grafts survived, and wounds healed by first intention. All patients were followed up 6-12 months (mean, 8 months). The color, texture, and contour of the flaps were good. According to total active motion standard, the finger function was assessed as excellent in 10 cases, good in 4 cases, and fair in 2 cases, and the excellent and good rate was 87.5%. Conclusion Radial dorsal fasciocutaneous flap of thumb is a reliable flap with easy dissection and less trauma in repair of severe nail bed defects.
Objective To investigate the cl inical effect and operative method of local island flap for complex thumb mutilation with soft tissue and blood vessel defect. Methods From May 2003 to March 2006, 6 cases of complex thumb mutilation with soft tissue and blood vessel defect were treated with local island flap. There were 4 males and 2 females aged 14-48 years, with an average of 23.5 years, among whom 2 cases were caused by triangular bandage twist, 3 cases by machinesavulsion and 1 case by explosion. Five cases suffered thumb mutilation of soft and blood vessel defect only, and 1 case was combined with middle and ring finger injures. The defect was located in pulp soft tissue in 4 cases and in dorsal soft tissue in 2 cases, ranging 2.0 cm × 1.2 cm-2.5 cm × 1.8 cm in size. The time from injury to operation varied from 30 minutes to 6 hours. Two cases were replanted with bridging index finger radial is digital artery island, 2 cases were repaired by ring finger radial is digital artery island and 2 cases by index finger near dorsi-flap. The flap was 2.0 cm × 1.4 cm-2.5 cm × 1.8 cm in size. Free-skin graft from forearm was conducted. Results All flaps free skin and replanted thumbs in 6 cases survived completely, following up for 6-24 months after operation. The flaps and thumb had good texture and color match, two-point discrimination was 10-12 mm on thumb pulp and 8-10 mm on flap. All replanted thumb recovered satisfied function, there were no donor site dysfunction. According to the criteria for function assessment of amputated finger issued by the Branch of Hand Surgery of Chinese Medicine Association：4 cases were regarded as excellent and 2 as good. Conclusion Local island flap is capable of repairing complex thumb mutilation with soft tissue and blood vessel defect, maximizing the recovery of thumb appearance and function.
