ObjectiveTo investigate the effectiveness of soft tissue balance technique by flexor pollicis longus (FPL) tendon transfer for Wassel Ⅳ-D thumb duplication in children. Methods A clinical data of 14 children with Wassel Ⅳ-D thumb duplication met the selection criteria between January 2017 and January 2021 was retrospectively analyzed. There were 5 boys and 9 girls with an average age of 21.6 months (range, 18-35 months). Ten cases were left hand deformity and 4 cases were right hand deformity. During operation, the radial thumb was excised, and the FPL tendon of the radial thumb was used to reconstruct the soft tissue balance of the ulnar thumb. Postoperative evaluation included the range of motion (ROM) of passive flexion and extension of the interphalangeal joint (IP) and metacarpophalangeal joint (MCP), the alignments of the IP and MCP, the percentage of the width of the nail plate and the circumference of the thumb at the level of the IP to contralateral thumb. Results All operations were completed successfully, and all incisions healed by first intention. The children were followed up 12-36 months (mean, 21.7 months). At last follow-up, the ROM of passive flexion and the deviation of the IP, and the deviation of the MCP significantly improved when compared with those before operation (P<0.05); the ROM of passive extension of the IP and the ROM of passive flexion of the MCP did not significantly improve when compared with those before operation (P>0.05). The ROMs of passive extension of the MCP were 0° before and after operation. The width of the nail plate was 76.6%±4.1% of the unaffected side, and the circumference of the thumb at the level of the IP was 92.0%±9.1% of the unaffected side. ConclusionThe soft tissue balance technique by FPL tendon trasfer can effectively correct the alignment of the Wassel Ⅳ-D thumb duplication in children, and maintain the correction effect effectively, but further follow-up and comprehensive evaluation are needed to investigate the long-term effectiveness.
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.
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.

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 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.
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 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.
