[Objective]To retrospectively analyze 39 cases of surgical treatment of fibrous dysplasia of proximal femur,in order to propose a partition method which can be used to guide the surgical treatment,and probe the surgical treatment strategy according to the partition method of fibrous dysplasia of proximal femur. [Methods]The data on 39 cases of fibrous dysplasia of proximal femoral from 1998 to 2009 were retrospectively analyzed.The study determined extent of the lesion according to preoperative X-ray film and proposed partitioning method in accordance with the scope of proximal femoral involvement,analyzed the relation of partition type and surgical treatment,and evaluated the effect of surgical treatment through the postoperative localized lesions control and functional score(MSTS 93).[Results]According to the scope of 39 cases of lesions,combined with characteristics of proximal femoral anatomy,proximal femur was divided into four zones: area I,femoral shaft(below small protuberance);area II,intertrochanteric(small rotor to the neck base division);area III,femoral neck;area IV,the femoral head.Based on the above partition,lesions were divided into 7 types,type I,type II,type III,type I + II,type II + III,type II + III + IV,type I + II + III,type I + II + III + IV.Surgical treatment was performed mainly with curettage of bone lesions,bone grafting and fixation.Internal fixation included DHS,intramedullary nails,and artificial joint replacement,DHS was most common in area II involvement(57.58%),followed by area III involvement(24.24%).Intramedullary nail was most common in area I involvement(64.70%) and area II involvement(35.30%).For lesions involving ≥3 zones,joint replacement was carried out.The patients were all followed up,with a median time of 6.3 years(0.5-11 years).Local recurrence rate was12.82%(5 / 39),local deformity was not found deterious.The followed up results were satisfactory.The selected treatment was reasonable.[Conclusion]When making a surgical treatment regimen for fibrous dysplasia of the proximal femur,Surgeons should consider lesion characteristics,and choose a reasonable internal fixation to achieve better surgical results.Partition method proposed in this paper can be formulated as one of preoperative surgical treatment options.

Objective To explore the application of combined penile and scrotum skin flap in the reoperation process for operation failure cases with hypospadias.Methods A retrospective analysis was performed with the inclu-sion of 1 5 failure cases with hypospadias who received combined penile and scrotal skin flap treatment for reoperation from January 201 3 to December 201 5 in the First Affiliated Hospital of Guangxi Medical University.These cases aged from 7 to 1 5 years old,with a median age of 1 0.2 years old.Among them,a 3 rd operation was performed in 4 cases,4th operation in 5 cases,5 th operation in 4 cases,and 6 th operation in 2 cases.The procedure of Onlay island flap urethro-plasty +tubularized incised plate (Onlay +TIP)urethroplasty was performed in 4 patients,and the other 1 1 cases were treated with urethral mouth basal vascular skin tube urethroplasty (Mathieu)+TIP urethroplasty.F8 or F1 0 silicone balloon catheter were used as stent in new urethra,outer dressing after operation was replaced every 2 to 3 d,the outer dressing was demolished 6 -8 d after operation.Results All patients were followed up after surgery until March 20, 201 6,the follow -up time was 4 -26 months.In these 1 5 patients,the success rate of operation was 86.7%(1 3 /1 5 ca-ses),among them,3 cases were success and 1 case was failed in Onlay +TIP group,and 1 0 cases were success and 1 case was failed in Mathieu +TIP group.The patients with successful operation were with beautiful appearance of the pe-nis,normal position of the meatus urinarius and normal urination.No peristome of urethra,urethrovaginal fistula or ure-thral diverticulum was found after surgery.However,urethral cracking of the glans of penis appeared in 2 operation failed patients,and the orificium urethrae externum was low -set,and urethroplasty was needed 1 year postoperatively. Conclusions For some failure cases with hypospadias showing suitable anatomy conditions,Onlay +TIP or Mathieu +TIP combined with penile and scrotal flap may be a good choice for the completion of reoperation.
