OBJECTIVETo study the applied value of double joystick technique in reduction-internal fixation for femoral shaft fracture in adults.
METHODSThirty-four patients (24 males and 10 females) with femoral shaft fractures were treated with reduction assisted by double joystick technique and internal fixation with interlocking intramedullary nail from September 2010 to June 2013. The average age of the patients was 41 years old, ranged from 17 to 65 years old. The duration of the disease course ranged from 3 to 7 days, with a mean of 5 days. The fractures belonged to AO types 32A (5 cases), 32B (20 cases) and 32C (9 cases) and located in left femur for 18 patients and right femur for 16 patients. The patients were followed up, and fracture healing and complications were observed. The curative effect were evaluated according to Thorsen femur fracture evaluation standard.
RESULTSThe operative time ranged from 40 to 110 min (mean 75 min) and intraoperative blood loss ranged from 200 to 300 ml (mean 250 ml). All the patients obtained a good fracture reduction and were followed up for 12 to 24 months (mean 18 months) after the surgery. All the fractures united between 4 and 8 months with a mean of 5 months. No complications such as breakage of nail, infection, osteofascial compartment syndrome, refracture and fracture malunion were found. According to Thorsen femur fracture evaluation standard, 30 patients obtained an excellent result, 3 good and 1 fair.
CONCLUSIONIn surgery of reduction-internal fixation for femoral shaft fracture in adults, the use of double joystick technique obtains good reduction result, short operative time, less injury, high healing rate of bone fractures, less complications and good limbs function, so it is worthy of popularizing in clinic.

BACKGROUND: It is a key point to revascularize the tissue-engineered bone during the repairing of large bone defect. Fascia flap is commonly used in clinic to accelerate the blood supply of implant.OBJECTIVE: To observe the feasibility of repairing goat tibia defects with tissue-engineered bone and accelerating revascularization with fascia flaps.DESIGN: Randomized and controlled animal experiment SETTING: Department of Traumatic Orthopaedics, Nanfang Hospital,Southern Medical University.MATERIALS: Totally 36 goats with the body mass of 14.5-15.5 kg of either gender were enrolled.METHODS: This experiment was conducted at the Department of Traumatic Orthopaedics, Nanfang Hospital, formerly the First Military Medical University of Chinese PLA from December 1999 and December 2003.Bone and periosteum defects 20 mm long were made and fixed with plate of left tibia in 36 goats. They were randomly divided into four groups: Group A in which the defects were filled with coral hydroxyapatite (CHAP), Group B I CHAP+ bone marrow stroma cells (BMSc); Group C with fascia flaps;Group D with nothing. Next, the bone regeneration and the revasculariza tion were evaluated. Radionuclide bone imaging was done 2, 4, 8 weeks after operation. After X-ray examination, the index of optical density of Xray films and histology of the implants were analyzed at 4, 8, 12 weeks after operation, and the biomechanical characters were studied 12 weeks postoperatively.MAIN OUTCOME MEASURES: Gross observation and X-ray, radionuclide bone imaging, biomechanical and histological observation RESULTS: Totally 36 goats entered the stage of result analysis. ① Gross observation of the repair sample of bone defects of the animals in each group: there was no osteogenesis postoperatively at each time point in the blank control group . In Group B, at week 8 to 12, there was no obvious osteogenesis and callus formation on the surface of the materials. In Group C,At weeks 8 to 12, bone defects were filled gradually, many bone callus processes were seen on the surface of the materials , centralizing and enwrapping the materials. The osteogenetic process in the Group C were superior to that of theGroup B. ②Examination result with -901/SA PET-CT scanners: It was seen by naked eyes that at weeks 2 to 8 in the Group A,the radioactivity concentration at region of interesting (ROI) of the operation side had obvious increasing trend, and similar trend of changing appeared in the Group B and Group C, but the ROI counts and T/NT value in the Group B were both lower than those in the Group C. The decreasing trend in the Group A was lower than that in the Group B. ③) Radiological results: the osteogenesis volume through measuring absorbance in the order from large to small was Group C, Group B, and Group A[At week 12, they were (4.180±0.192), (3.480±0.453), (2.959±0.682)respectively ].④Biomechanical results: there were significant difference of loading and bending stress in the Group C, Group B and Group A [ The loading was (758.333±88.754), (530.214±65.297), (359.667±60.715)N , respectively; and the bending stress was (13.937±2.199), (10.123±1.243),(6.223±0.945)N/mm2, respectively ].⑤)Histological results: Slices at various time points in the blank control group showed no bone tissue. In the other three 3 groups, with the prolongation of time, the osteagenetic range and quality were in the order of Group C, Group B and Group A.CONCLUSION: The fascia flaps can accelerate the revascularization process in the formation of tissue-engineered bone so that the capability of tissue engineered bone to repair the large bone defects may be enhanced.
