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.
Since 1992, the retrograde island skin flap with its pedicle containing the arteria pollicis dorsalis was used to repair 6 cases of the fingertip defects and the results were successful. The skin measured from 1.5cm x 2cm to 4cm x 3.5cm. From the followup, the external appearance of the thumbs looked nice, no limitation of joint motions was noticed and the pain sensation was recovered. The major improvement of this operation was that the donor skin was chosen from the dorsum of the first and second metacarpal bones, thus it was not necessary to divide the tendon of the extensor pollicis brevis, so that the operative procedure was simple and the postoperative functional recovery was rapid.
Objective To investigate the therapeutic effect of minimally invasive small incision surgery under local anesthesia for pediatric stenosing tenovaginitis of thumb. Methods A retrospective analysis was conducted on the medical records of children with stenosing tenovaginitis of thumb who received small incision tendinolysis under local anesthesia at West China Hospital of Sichuan University between January 2013 and August 2022, to evaluate and analyze the safety and effectiveness of the surgery. Results A total of 949 pediatric patients were included, with an average age of (3.23±1.92) years. The average duration of surgery was (7.0±2.5) minutes, and the average follow-up time was (3.91±5.32) months. All patients did not need to fast for solids and liquids before surgery, and were immediately discharged from the hospital after outpatient surgery. The family members of the patients were highly satisfied with the treatment process and postoperative recovery. All patients had no nerve or vascular damage, and the wound margin skin showed linear healing with mild scars that fused with palm prints. There were 825 cases (86.93%) of children with thumb function fully restored to normal, 113 cases (11.91%) with limited maximum dorsiflexion function of the thumb, and 11 cases (1.16%) with recurrent stiffness of the thumb metacarpophalangeal joint. Conclusion Small incision tendinolysis under local anesthesia is a safe and effective treatment for pediatric stenosing tenovaginitis of thumb, with high satisfaction among the patients’ family members.
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 replantation of amputated finger (or limb) and the reconstruction of the thumb and fingers started in 1960s in China. With the development of microsurgical techniques, both finger replantation and reconstruction achieved worldwide significant success. And now it is not the survival rate but the function of replanted finger that attracted more attention. Moreover, the breakthrough of particular type of digital replantation has broadened its indications. In terms of reconstruction, not only that a great deal of experiences in dealing with different types of thumb defects was accumulated, but also more micro-surgeons focus on minimal invasion and reducing the damage to the donor area.
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.
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.
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.

Objective To investigate the effectiveness of transferring the ulnaris proper digital nerve of index finger and its dorsal branch to repair the thumb nerve avulsion. Methods Between January 2007 and May 2015, 23 patients with thumb nerve avulsion were treated by transferring the ulnaris proper digital nerve of index finger and its dorsal branch. There were 17 males and 6 females with an average age of 32 years (range, 16-63 years). The injuries were caused by machine twist in 10 cases, electric saw in 8 cases, and sharp article prick in 5 cases. And thumb rotational avulsion amputation happened in 8 cases, thumb incomplete amputation in 2 cases, laceration of thumb palmaris with the thumb nerve avulsion of both sides in 13 caese (7 cases with tendon rupture). The time from injury to operation was 1.0-3.5 hours (mean, 2.2 hours). Results All incisions healed by first intention. Ten cases of thumb reimplantation were successful. All the patients were followed up for 5 months to 2 years and 8 months, with an average of 1 year and 4 months. Two-point discrimination was 3-9 mm (mean, 6.8 mm). According to Society of Hand Surgery standard for the evaluation of upper part of the function, the sensory of the thumb was rated as S4 in 18 cases and \begin{document}${{\rm{S}}_{\scriptsize{3^ + }}}$\end{document} in 5 cases; the sensory at donor sites recovered to S3. Conclusion Transferring the ulnaris proper digital nerve of index finger and its dorsal branch to repair the thumb nerve avulsion is a simple and effective method to restore sensory function of the thumb pulp.
