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.

Objective:To observe the effect of stereotactic aspiration combined with corresponding drug therapy in the treatment of cerebral hemorrhage induced by different drugs. Methods:Totally 66 patients with hemorrhage induced by antithrombotic drugs were randomly divided into the control group and the treatment group with 33 cases in each. The control group was given corresponding drug therapy according to the pathogenesis of cerebral hemorrhage, and the treatment group was treated by stereotactic hematoma aspiration additionally. Daily life ability, NIHSS and prognosis improvement were compared between the two groups before and after the treat-ment. Results:After the treatment, NIHSS of the treatment group was ( 10. 17 ± 2. 97 ) and Barthel index score was ( 59. 97 ± 12. 10), which were both better than those of the control group (P<0. 05). The prognosis of the treatment group was also better than that of the control group (P<0. 05). There was no severe adverse drug reaction in the two groups. Conclusion:For different drug in-duced cerebral hemorrhage, corresponding drug therapy should be carried out, and combining with stereotactic hematoma aspiration, the therapeutic regimen can effectively improve neurological deficits and activities of daily living of the patients, and then improve the prognosis of the patients with promising safety.
