OBJECTIVE: To introduce a surgical approach for reconstruction of nail folds in congenital complete syndactyly release. METHODS: A narrow flap and a broad flap were raised on the common distal phalanx to cover the denuded nail-edge in 30 fingers of 15 cases whose webs were separated. RESULTS: All of the flaps were successfully transferred and survived. The reconstructed nail folds had satisfied figure in 21 out of 30 fingers. The nail folds in the other 9 fingers, covered by a broad flap in 2 fingers and by a narrow flap in 7 fingers, were a little smaller than normal. All of the 30 fingers had normal fullness of pulp and no twisty nails. CONCLUSION: The reconstruction of nail folds by double pulp flap can be performed with a one-stage technique, and the outcome is satisfactory, which make it as a good surgical approach to reconstruct nail folds in congenital complete syndactyly release.
ObjectiveTo investigate the effectiveness of dorsal pentagonal flap for reconstruction of the web space in congenital toe syndactyly. MethodsBetween January 2009 and June 2014, 10 patients with congenital toe syndactyly were treated for web space reconstruction with dorsal pentagonal flap. There were 6 boys and 4 girls with the average age of 42 months (range, 8 months to 9 years). The congenital toe syndactyly located at the left foot in 5 cases, the right foot in 4 cases, and both feet in 1 case; 7 patients had polydactyly and 1 patient had brachydactylia. During followup, the toe function and web space appearance, web space depth, and web space gradient were observed to evaluate the effectiveness. ResultsAll 13 flaps survived and incisions healed by first intention. Ten patients were followed up 6-50 months (mean, 26 months). The skin color and texture in 13 reconstructed web spaces were close to normal web space. In 9 patients undergoing web spaces reconstruction of single foot, the abduction angle of toes was (42.879±3.703)° at the injured side, showing no significant difference when compared with the normal side [(45.922±2.657)°] (t=-2.004, P=0.062); the web space depth was (1.881±0.266) cm at the injured side and was (1.631±0.202) cm at the normal side, showing significant difference (t=2.248, P=0.039); and the web space gradient was (42.733±3.421)° at the injured side and was (41.189±5.593)° at the normal side, showing no significant difference (t=0.707, P=0.490). The web space appearance, web space depth, and web space gradient were close to those of the normal web space in 1 patient undergoing bilateral web spaces reconstruction. ConclusionWeb space reconstruction with dorsal pentagonal flap is easy to perform with reliable blood supply and low re-operated rate. The cosmetic and functional results are satisfactory.
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 discuss the effectiveness of using dorsal two wing-shaped advancement flap to reconstruct finger web for treatment of congenital syndactyly.MethodsBetween August 2014 and August 2017, 30 cases of congenital syndactyly were treated, including 18 males and 12 females with an average age of 2.5 years (range, 1.5-5 years). Eight cases were of bilateral hands syndactyly and 22 cases of single hand syndactyly. There were 39 webs of syndactyly (including 1 case of syndactyly of middle finger, ring finger, and little finger). Among them, 11 webs were complete and 28 webs were incomplete. At the dorsum, a flap with V-shaped tip and two wing-shaped pedicle was designed and was just sewed up with an anchor-shaped incision at the palm. Distal end of fingers were separated by serrated flap and were sutured after removal of fatty tissue. In 11 cases with tight skin connection, the defect area at lateral and distal end of fingers was repaired by small pieces of full-thickness skin graft.ResultsAll the flaps survived completely after operation, and no flap necrosis occurred. The skin grafts on the distal side of the finger survived and the wound healed by first intension. All 30 cases were followed up 6-12 months, with an average of 9 months. Postoperative flexion and extension function of fingers were good, and the web depth and width were normal. At last follow-up, according to the Swanson et al. standard, 20 fingers were graded as excellent, 8 as good, and 2 as fair, with an excellent and good rate of 93.3%.ConclusionThe effectiveness of using dorsal two wing-shaped advancement flap to reconstruction finger web for treatment of congenital syndactyly is satisfactory.
ObjectiveTo explore the application of the dorsal foot hexagonal flap for reconstruction of the web space in the fourth and fifth toe syndactyly combined with polydactyly.MethodsBetween May 2016 and October 2019, 27 patients (34 feet) with the fourth and fifth toe syndactyly combined with polydactyly were treated, including 12 males and 15 females with an average age of 22.8 months (range, 10 months to 8 years). There were 7 bilateral feet and 20 unilateral foot. Twenty-four of which were incomplete and 10 were complete syndactyly of the fourth and fifth toes, and the fifth toes showed various degrees of fibular deflection. All the 34 feet were treated with one-stage reconstruction of the toe web with the dorsal foot hexagonal flap, and the correction of the fibular deviation of the fifth toe was made by removing the tibial polydactyly and using the articular surface dressing or wedge osteotomy.ResultsAll wounds healed by first intention without skin-frafting. All patients were followed up 6-36 months (mean, 18 months). There was no flexion contracture and obvious scar hyperplasia in all the patients, and the width and slope of the toe webs were normal. Three of the 34 webs developed web creep, and the rest of the toe webs were normal in depth. All 34 feet were corrected with peroneal fibular deviation, and the function of toe flexion was good. All parents of the children were satisfied with the outcome.ConclusionThe reconstruction of toe webs with dorsal foot hexagonal flaps for the treatment of the fourth and fifth toes syndactyly combined with polydactyly requires no skin graft. The operation is simple with high survival rate of the flap, the appearance and function of the toes are good, and the effectiveness is satisfactory.
Poland syndrome is a congenital anomaly characterized by unilateral underdeveloped or absent chest wall, accompanied by varying degrees of ipsilateral limb defects. In clinical practice, Poland syndrome is prone to misdiagnosis and missed diagnosis, which delays treatment timing and affects treatment effectiveness, as the current etiology is not yet clear and there is no unified and standardized clinical classification and treatment plan. This article summarizes and elaborates on the etiology, clinical manifestations, classification, diagnosis, and treatment of Poland syndrome by reviewing relevant literature on the diagnosis and treatment of Poland syndrome both domestically and internationally in recent years, in order to enhance understanding of Poland syndrome, provide reference for standardized clinical diagnosis and treatment, and improve the efficiency of diagnosis and treatment.
