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.
Objective To investigate the effectiveness of the second dorsal metacarpal artery fascial vascular pedicle retrograde island flap relaying the dorsal island flap of the index finger in repairing skin and soft tissue defects of the thumb. Methods The clinical data of 8 patients with skin and soft tissue defects of thumb between October 2019 and January 2021 were retrospectively analyzed. There were 3 males and 5 females with an average age of 35 years (range, 18-52 years). The causes of injury included machine injury in 2 cases, crush injury in 3 cases, and cutting injury in 3 cases. There were 2 cases of dorsal defect of the proximal part, 1 dorsal defect of the distal part, and 5 instances of the distal part defect. The skin and soft tissue defects ranged from 1.7 cm×1.4 cm to 3.0 cm×2.5 cm. The time from injury to flap repair was 7-21 days, with an average of 14 days. Firstly, the dorsal island flap of the index finger (dorsal side of the proximal part of the index finger) was used to repair the defect of the thumb. Then the second dorsal metacarpal artery fascia vascular pedicle retrograde island flap (near the radial side of the back of the hand) was used to repair the dorsal defect of the index finger; the donor site was sutured directly. ResultsVascular crisis of the flap occurred in 1 case within 48 hours after operation, and the flap was bloated and bruised in 1 case due to excessive suture tension, and all the flaps survived after symptomatic treatment; partial skin margin of the flap was necrotic in 1 case after operation, and the incision healed after dressing change; the other 5 flaps survived, and all the wounds in the donor and recipient sites healed by first intention. All the 8 patients were followed up 3-10 months, with an average of 6 months. One patient had mild scar; the other patients had no significant difference in the color of the flap and the surrounding skin, no adhesion of tendons, and little interference of index finger function, and there was no obvious pain and dysfunction in the donor and recipient sites of the flap. At last follow-up, the extension-flexion range of motion of the metacarpophalangeal joint of the thumb was 0°-55°, and that of the interphalangeal joint was 0°-75°; the extension-flexion range of motion of the metacarpophalangeal joint of the index finger was 0°-82°, that of the proximal interphalangeal joints was 0°-90°, and that of the distal interphalangeral joints was 0°-65°. Conclusion The application of the second dorsal metacarpal artery fascial vascular pedicle retrograde island flap relaying the dorsal island flap of the index finger to repair skin and soft tissue defect wounds of thumb is a feasible treatment with reliable blood supply, less postoperative complications, no need for skin grafting, less interference to the function of the index finger, and satisfactory wound repair effect.
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.
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.
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.
Objective To explore the effectiveness of thumb blocking technique through closed reduction of ulnar Kirschner wire threading in the treatment of Gartland type Ⅲ supracondylar humerus fractures in children. MethodsThe clinical data of 58 children with Gartland type Ⅲ supracondylar humerus fractures treated with closed reduction of ulnar Kirschner wire threading by thumb blocking technique between January 2020 and May 2021 were retrospectively analyzed. There were 31 males and 27 females with an average age of 6.4 years ranging from 2 to 14 years. The causes of injury were falling in 47 cases and sports injury in 11 cases. The time from injury to operation ranged from 24.4 to 70.6 hours, with an average of 49.6 hours. The twitch of ring and little fingers was observed during operation, the injury of ulnar nerve was observed after operation, and the healing time of fracture was recorded. At last follow-up, the effectiveness was evaluated by Flynn elbow score, and the complications were observed. Results There was no twitch of the ring and little fingers when the Kirschner wire was inserted on the ulnar side during operation, and the ulnar nerve was not injured. All children were followed up 6-24 months, with an average of 12.9 months. One child had postoperative infection in the operation area, local skin redness and swelling, and purulent secretion exudation at the eye of the Kirschner wire, which was improved after intravenous infusion and regular dressing change in the outpatient department, and the Kirschner wire was removed after the initial healing of the fracture; 2 children had irritation at the end of the Kirchner wire, and recovered after oral antibiotics and dressing change in the outpatient department. There was no serious complication such as nonunion and malunion, and the fracture healing time ranged from 4 to 6 weeks, with an average of 4.2 weeks. At last follow-up, the effectiveness was evaluated by Flynn elbow score, which was excellent in 52 cases, good in 4 cases, and fair in 2 cases, and the excellent and good rate was 96.6%. ConclusionThe treatment of Gartland type Ⅲ supracondylar humerus fractures in children by closed reduction and ulnar Kirschner wire fixation assisted with thumb blocking technique is safe and stable, and will not cause iatrogenic ulnar nerve injury.
Objective?To investigate the effectiveness of the island flap pedicled with the dorsal cutaneous branches of thumb radial digital artery from the same finger for repairing pulp defect.?Methods?Between June 2009 and March 2010, 10 patients (10 fingers) with pulp defect of thumb were treated. There were 6 males and 4 females, aged 13-68 years with an average of 38 years. Defect was caused by machine crush in 4 cases, by saw machine in 3 cases, by chronic infection in 2 cases, and by burn in 1 case. The disease duration was 3 hours to 4 months. In 4 cases of distal pulp defect (1.0 cm × 0.8 cm to 2.0 cm × 1.4 cm) with exposure of bone or tendon, defect was repaired with island flap pedicled with the interphalangeal joint cutaneous branches of thumb radial digital artery (1.0 cm × 0.8 cm to 2.2 cm× 1.5 cm). In 6 cases of proximal pulp defect (1.0 cm × 0.8 cm to 2.5 cm × 2.0 cm) with exposure of bone or tendon, defect was repaired with island flap pedicled with the metacarpophalangeal joint cutaneous branches of thumb radial digital artery (1.0 cm × 0.8 cm to 2.6 cm × 2.2cm). The donor sites were repaired with skin grafts.?Results?All flaps and skin grafts survived, and wounds healed by first intention. Ten cases were followed up 6-12months (mean, 8 months). The colour, texture, and contour of the flaps were good. The two-point discrimination was 7-10mm on the island flap at last follow-up. According to total active motion (TAM) standard, the thumb function was assessed as excellent in 8 cases, good in 1 case, and fair in 1 case, and the excellent and good rate was 90%.?Conclusion?The main digital artery and nerve of thumb will not be sacrified when the island flap pedicled with the dorsal cutaneous branches of thumb radial digital artery is used. The operative procedure is simple, so it is a good method for repairing pulp defect of thumb.
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.
