ABSTRACT
Objcetive@#To explore the treatment of long segment defect of tibia by using tensor fascia lata combined with iliac flap or deep circumflex iliac pedicle iliac flap.@*Methods@#From February 2012 to August 2017, The People′s Hospital of Zun Yi City Bo Zhou District treated 16 patients who had long segment defect of tibia.There were 11 males and 5 females, age from 22 to 58 years old, the average age was 42 years old. Iliac flap grafting with tensor fascia lata combined with iliac flap or deep circumflex iliac pedicle was used to treat the defect of long segment of tibia. There were 4 cases with simple tibial defect and 12 cases with skin defect. The longest tibial defect was 5-8 cm.@*Results@#In this study, four patients used iliac flaps with deep circumflex iliac pedicle, the area of flaps ranged from 2.5 cm×5.0 cm to 5.0 cm×10.0 cm, while the area of iliac flaps ranged from 5.0 cm×2.5 cm to 8.0 cm×4.0 cm. Twelve patients used grafting with tensor fascia lata combined with iliac flap, the area of flaps ranged from 5.0 cm×12.0 cm to 12.0 cm×23.0 cm, while the area of iliac flaps ranged from 7.0 cm×2.0 cm to 8.0 cm×4.0 cm. All 16 cases of bone flap were survived, fracture healing, without surgical complications. The average follow-up period was 1.5 years, the flaps had good appearance in 10 cases and was slightly bloated in 6 cases; the ankle had normal motion in 14 cases and had poor dorsal extension in 2 cases. X-ray films showed that the bone flap repaired the bone defects and reached bone healing.@*Conclusions@#Vascularized tensor fascia lata combined with iliac flap or deep circumflex iliac pedicle iliac flap grafts increase local blood supply and accelerate the process of fracture healing.
ABSTRACT
Objective To investigate the effect of iliac flap pedicled with superficial circumflex iliac artery and sartorius in the treatment of femoral neck fracture of the young adults.Methods From April,2012 to March,2017,50 cadaveric lower limbs were injected with red latex,and the origin,diameter,course and distribution of the superficial circumflex iliac artery and arteries of the sartorius were observed.The iliac flap pedicled with superficial circumflex iliac artery and sartorius was used to treat the femoral neck fracture in young adults in 11 cases.There were 9 males and 2 females with an average age of 34.5(ranged from 16 to 54) years.The fractures were classified ac cording to Garden:4 cases of type Ⅲ and 7 cases of type Ⅳ.Regular outpatient follow-up was made.Results The superficial circumflex iliac artery originated from the femoral artery and the initial diameter was (1.2±0.3) mm.The length of the superficial circumflex iliac artery to the anterior superior iliac spine was (8.8±1.3) cm.The superficial circumflex iliac artery run to the anterior superior iliac spine and sent 1-3 periosteal branches into the iliac crest.The sartorius originates from the anterior superior iliac spine,and its proximal artery arises from the superficial circumflex iliac artery and the femoral artery.Link-pattern arterial anastomosises were formed in sartorius by branches of adja cent vascular pedicles,which nourished the ilium flap.All incisions healed by first intention.All cases were followedup from 16 to 42 months,with an average of 32.3 months.All fractures healed for 3-7 months,with an average of 4.6 months.No fracture nonunion,femoral head necrosis and other complications occurred.Harris hip scores was 93.02± 5.33.Seven cases were excellent and 4 cases were good.Conclusion The iliac flap pedicled with superficial cir cumflex iliac artery and sartorius has rich blood supply,easily performed conducive to promoting fracture healing,and reducing the occurrence of femoral head necrosis.It is an effective method for the treatment of femoral neck fracture in young adults.
