Objective To discuss the classification and treatment of the degloving hand.Methods All 68 degloving hand treated between January, 2005 and December, 2014 in our department were reviewed.The cases were divided into three types according to the extent of the injury.Type Ⅰ the degloving tissue had enough blood supply which was debrided and stitched.Type Ⅱ the degloving tissue had less or no blood supply which was revascularized with replantation or vein anastomosis, some degloving palm or dorsum resurfaced the wound by the degloving skin graft.Type Ⅲ the degloving tissue had no blood supply or severely damaged,the tissue defect should be resurfaced with other tissue reconstruction.Type Ⅱ and Ⅲ were further divided into subtype A, B and C depending on the degloving scope and location, each subtype has its own surgical procedure.Results The total survival rate was 83.8％.The survival rate decreased with the increasing extent of the injury and the increasing degloving scope.Conclusion Classification of the hand degloving injuries depending on the extent of the injury, the degloving scope and location is useful for the assessment of injury and the selection of proper operation procedures.

Objective To evaluate the supercutaneous fixation with locking plate for treatment of open metacarpal fractures.Methods From March 2015 to November 2016,16 open metacarpal fractures were treated with supercutaneous locking plate after emergency debridement at Department of Hand Surgery,The Second Affiliated Hospital to Wenzhou Medical University.They were 11 men and 5 women,from 20 to 67 years of age (average,37.5 years).There were 2 cases of the 1st metacarpal fracture,6 ones of the 2ed metacarpal fracture,one of the 3rd metacarpal fracture,2 ones of the 4th metacarpal fracture and 5 ones of the 5th metacarpal fracture.All fractures were open injury.By the Gustilo-Anderson classification,there were 9 cases of type Ⅱ and 7 ones of type Ⅲ A.Functional rehabilitation was encouraged immediately after operation.The outcomes were evaluated at the 4th and 24th weeks postoperatively according to the Total Angle of Motion (TAM) for digital joints recommended by the Hand Surgery Society,Chinese Medical Association.Results The mean operation time was 46.8 minutes (from 35 to 108 minutes).All cases were followed up for an average of 9.8 months (from 7 to 25 months).All fractures healed without breakage or loosening of the supercutaneous locking plate after an average of 6.2 weeks(from 4.3 to 7.8 weeks).Nail tract infection occurred in 3 cases.According to the TAM at the 4th week postoperatively,5 cases were rated as excellent,8 as good,2 as fair and one as poor;according to the TAM at the 24th week postoperatively,11 cases were rated as excellent,4 as good and one as fair.Conclusion For open metacarpal fractures with severe contamination or soft tissue injury,supercutaneous locking plate fixation can achieve fine clinical outcomes.

Objective To investigate the therapeutic effect of modified dorsal metacarpal artery island flap of index finger without skin graft in repairing different types of soft tissue defect of thumb tip.Methods From August,2015 to October,2017,25 patients with soft tissue defect of the thumb tip were included in the study.Sixteen cases were males and 9 cases were females.Seventeen defects were in thumb dorsal and 8 cases were in thumb pulp.A modified dorsal island flap of index finger was used and the dorsal metacarpal superficial vein fascial flap could be harvest and combined to repair the thumb pulp defect if necessary.A relaying perforator flap pedicled on the second dorsal metacarpal artery was raised through the same incision to cover the donor site without skin graft.Followed-up was made by clinic,telephone and WeChat.Results The patients were followed-up for 6 to 18 months.All flaps survived completely without complications.The color,texture and contour of the flaps was good.Only 1 linear scar was left in the dorsum of the hand and no skin grafts.The second dorsal metacarpal artery flap was used to cover the donor site.Twenty-one cases (84％) were satisfied with the postoperative appearance of the thumb.The function was assessed as excellent in 16 fingers,good in 6 fingers and fair in 3 fingers.No complication occurred in the donor site.Conclusion It is possible to use the modified dorsal island flap of index finger to repair different types of thumb tip defects.A second dorsal metacarpal artery flap can be used as a relaying flap to cover the donor site without skin grafts.

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" .
