Objective To discuss the clinical influence and advantages of applying the local flap of finger tip lateral skin to repair the fingertip defective injuries.Methods From August,2013 to December,2015,used the way of local the flap of finger tip lateral skin to repair the first-fourth fingertip defects for 32 cases and 32 fingers,among which there were 20 males and 12 females;finger categories:11 thumbs,9 index fingers,8 middle fingers and 4 ring fingers.The defective area of fingertips was 0.5 cm×0.8 cm-1.0 cm×1.5 cm,all with bone exposure,23 cases had defects at the end part of phalanx,32 cases had different extent of nail bed defects.Reasons for the injuries:13 cases of grind injuries,11 cases of punch pressing injuries,8 cases of sharp tool cutting injuries.The time from injury to the treatment was 0.5-3.0 h,all of them had no associated injuries.Results Thirty-two cases of finger flaps all survived,with the follow-up for 3-24 months and average follow-up of 6 months,the flaps were slightly bloated after 3 months comparing with the normal skin,there was no contracture in the flap area and pedicle scars,two-point discrimination was 4-5mm,the farinterphalangeal joint flexion was normal.Conclusion The local flap of fingertip lateral skin can repair the defects of fingertip with less scar,not bloated flap,satisfying appearance,operation is simple,and good function,so it's the ideal way to repair the defects of fingertip.

Objective:To explore the clinical application of distal and proximal bilateral lateral pre-decompression in replant of digit degloving injury.Methods:From March 2012 to May 2021, 14 patients with 29 digits had replantation surgery of degloved soft tissue and severed digits in Section II, Department of Orthopaedics, Changzhou Medical District of 904th Hospital of PLA Joint Logistic Support Force. There were 2 types of injuries: degloving injury of soft tissue but with intact digital tip, and digital tip degloving injury with intact distal phalanx and nail bed. With the technique of distal and proximal bilateral lateral pre-decompression, pre-decompression incisions were made to the subdermal on both sides of the degloved skin over the proper palmar digital arteries. From where, the distal stump of the proper palmar digital arteries and nerves for anastomosis were found and had them anastomosed with the proximal proper palmar digital arteries and proper palmar digital nerves, then anastomosed digital pulp and digital dorsal veins (11 cases were direct anastomosis and 3 cases were bridged anastomosis). Follow-up was carried out by outpatient consultation, telephone and WeChat APP. The appearance of the digit body, the shape of digital pulp, the nails grow and the motions of the digits were observed, and the Evaluation Standard of Replantation of Severed Fingers by the Society of Hand surgery of Chinese Medical Association was used to evaluate the recovery of function.Results:All 29 segments of degloving digit survived. Small necrotic areas was found in 4 digits and healed after the change of dressing. The followed-up time was lasted for 3-36 months. There was no obvious atrophy found in all the digits. Appearances of digit pulp and nails were satisfactory with good sensational recovery for TPD at 6-10 mm, 7 mm in average. Motions of all the repaired digits were good. According to the Evaluation Standard of Replantation of Severed Fingers by the Society of Hand surgery of Chinese Medical Association, 23 digits were in excellent, 4 in good and 2 in poor, with a satisfactory rate at 93.1%.Conclusion:For a distal digit injury with intact distal soft tissue and relatively mild injury of blood vessels and nerves, using the method of distal and proximal bilateral lateral pre-decompression can help to achieve good appearance in survived digital pulp, good sensational recovery and good nail growth. An individualised treatment intra-and-after the surgery could offer an ideal therapeutic effect.
