RESUMO
Objective To summarize clinical experience in application of nail-bed lengthening operation for fingertip injuries.Methods From September 2003 to May 2007,36 patients (25 men and 11 women) aged 16 -45 years (26 in average) with nail defect by fingertip injuries underwent reconstruction operation using nail-bed lengthening at Orthopaedics and Traumatology Hospital of Taizhou,with the thumb involved in 15 cases,the index finger in 10 cases,the middle finger in eight eases and the ring finger in three case.A skin rectangle with thickness of 2 - 3 mm and width as that of the nail was resected at the skin edge 5 -6 mm distant from the epenychium,without damage to underlying subcutaneous vascular network, and U-shape skin flap was delicately slid proximally with its ends sutured.Results All surgical operations for nail lengthening were uneventful and clinically satisfactory,and the appearance of the thumb or other fingers was good during follow-up for six months to three years (19 months in average).Conclusions Nail lengthening for fingertip injuries with nail defect is a simple and effective surgical operation which could improve the appearance of the thumb and other fingers.
RESUMO
Objective To summarize clinical application of the medial sural artery perforator pedicled flap for the coverage of soft tissue defects around the knee and upper one third of lower leg.Methods From May 2003 tO January 2007,16 patients(11 men,5 women)with soft tissue defects around the knee and upper one third of lower leg underwent reconstruction with the medial sural artery perforator pedicled flap.Of them,4 eases recipient site were located on the prepatellar region,2 cases were located on the anterolateral pateflar,1 case was located on the anteromedial patellar,and 9 cases upper one third oflowerleg.They ranged in age from 23 to 52 years(mean,36 years).The donor leg was ipsilateral in all cages. Results One ca8e sustained superficial infection postoperative and the gradual wound healed by daily wound dressings.All the flaps had survived completely without major complication with satisfactory clinical results. Follow-up period ranged from 3.0 months to 3.5 years(mean, 1.7 years)postoperatively.There was no remarkable donor site morbidity.All cases had good appearance and function in recipient site.There was no remarkable donor site morbidity. Conclusion The medial sural artery perforator flap is nourished by the musculocutaneous perforater of the medial sural artery.The flaps seem to has highly vascularize,a constant vascular anatomy and a long vascular pedicle.The flap is thin and suitable for the coverage of soft tissue defects around the knee and upper one third of lower leg.
