Repairation of composite distal soft tissue defect of thumb and finger with mini toenail flap / 中华显微外科杂志

To introduce the repairation procedure of composite distal soft tissue defect of thumb and finger with mini toenail flap. Methods From June, 2015 to June, 2018, 7 cases with composite tissue defect at 7 distal fingers, including 5 thumbs, 1 index finger and 1 middle finger, were reconstructed with mini toenail flap transfer.The flap sizes which were raised during the operation ranged from 4.5 cm×3.0 cm-3.0 cm×1.5 cm.The donor sites were covered by toe phalanx shortening, V-Y advancement flap and local pedicle flap. Microsurgical routine treatment was made after the operation, and followed-up regularly. Results Seven flaps of 7 cases completely sur-vived without any necrosis. All the wounds at the donor sites healed well. All patients were followed-up for 6-36 months. The motive, sensor and cosmetic result were satisfied. In sensory function, the two-point discrimination dis-tance could restore to be 4-6 mm. Conclusion The mini toenail flap transfer is a reliable and suggested method.It can anatomically restored the distal digit sensor function with cosmetic contour, and regain the motive, sensory func-tion and satisfied cosmetic appearance.

Treatment of the defect on fibular hallux flap donor site with the tibial island flap of second toe / 中华整形外科杂志

Objective@#To discuss the therapeutic effect of using tibial island flap of second toe for the treatment of fibular hallux flap donor site defect.@*Methods@#From March 2012 to April 2015, 18 tibial island flaps of second toe were transferred to repair donor site defect on fibular hallux that can not sutured directly, and the subsequent donor site wound on the second toe were sutured.@*Results@#On an average of 13 months follow-up, all 18 flaps survived with primary healing. Texture and appearance of the tibial island flaps were satisfactory; The flaps had good sensory recovery, S3+ in 14 patients and S4 in 4 patients. Severe contracture of the first toe web were not observed. The donor site of second toe got good recovery with normal activity of interphalangeal joint.@*Conclusions@#The tibial island flap of second toe is a good option for treatment of the defect on fibular hallux flap donor site. Meanwhile, it also meets the requirement of " donor site care" .

Reading man flap for repair of soft tissue defects in distal fingers / 中华显微外科杂志

Objective To explore the Reading man flap for the treatment of soft tissue defects in distal fin-gers. Methods From May, 2014 to June, 2017, Reading man flaps were transferred in the emergency room to repair soft tissue defects in distal fingers in 46 patients. There were 28 cases of finger pulp defects, 6 cases of dorsal defects and 12 cases of finger stump defects with the size of soft tissue defects ranged from 1.0 cm×0.9 cm to 2.2 cm×2.0 cm (average, 1.2 cm×1.3 cm).The volar, dorsal and hybrid flaps were 28, 6 and 12 cases respectively.The average size of the major flap and minor flap were 1.8 cm×1.2 cm and 1.4 cm×0.8 cm, respectively. All donor sites were sutured di-rectly.All patients were followed-up by review in the outpatient department. Results The consumed operative time was 35-48 min, with an average of 37.8 min. Prophylactic antibiotics and wound dressing were conducted postopera-tively. The tip of the minor flaps occurred inflammation and small blister in 2 cases and eased by removal of the tip sutures.Traumatic neuralgia occurred in 1 case and self-healed after 3 months.Twenty-six cases were followed-up at least 11 months, which were 16 cases of finger pulp defects, 3 of dorsal defects and 7 of finger stump defects. On an average of 10.5 (9-27) months followed-up, all flaps survived. Except 4 cases with slim hook nail deformity, the re-maining flaps were observed with satisfactory texture and appearance, the bulky deformity and scar contracture did not occur.Two points distinguishment on the major and minor flaps were 3.3-6.2 (average, 4.5)mm and 5.5-9.8(average, 7.1)mm respectively. According to the Trial Standard for Evaluation of Upper Limb Function of Chinese Society of Hand Surgery, it was excellent in 28 cases, good in 11 cases and moderate in 7 cases, with the overall excellent and good rate of 84.8%. Conclusion The Reading man flap is a good option for treatment of the small size soft tissu de-fect in distal fingers with the advantages of simple procedure, high success rate, good appearance and sensory recovery.

Clinical application of finger soft tissue defect coverage with dosal proximal digit fatty fasciocutaneous flap / 中华显微外科杂志

Objective To discuss the coverage of finger soft tissue defect with dorsal proximal digit fasciocutaneous flap on the middle and distal digit.Methods From May,2013 to December,2014,8 cases with soft tissue defects at 8 fingers were treated with dorsal proximal digit fasciocutaneous flap.The flap sizes ranged from 2.5 cm × 2.0 cm to 3.5 cm × 3.0 cm.The donor site were closed straightly.Results Eight flaps of 8 fingers survived.All the wounds at the donor sites healed well.Eight fingers in 8 cases were followed up for 6-12 months.The color,texture and contour of the flaps were satisfied.The two-point discrimination distances were 8-10 mm.Conclusion The skin defect in the middle and distal digit can be satisfied covered with dorsal proximal digit fasciocutaneous flap.This flap is a simple,reliable and safe management for digit defect and can be performed in the primary hospital.To ensure the surviving of the flap,ensure the surviving of the flap,the awareness of the anatomy of the flap should be known well.The limits of its reconstruction of sensation and coverage size exit in its application.
