ABSTRACT

Objective:To discuss the causes and solutions for failed anterior ring fixation for unstable pelvic fractures.Methods:A retrospective analysis was conducted of the 84 patients who had been admitted to Department of Orthopedics and Joint Surgery, Jiangmen Central Hospital for unstable pelvic fractures from January 2009 to March 2019. They were 56 males and 28 females, aged from 19 to 64 years (mean, 42.5 years). By the Tile classification, 22 cases were type B1, 16 type B2, 10 type B3, 22 type C1, 6 type C2 and 8 type C3. Simple anterior ring fixation was performed for 21 cases and combined anterior and posterior ring fixation for 63 ones. The Matta's criteria were applied for the evaluation of fracture reduction. The cases of failed anterior ring fixation and their solutions were recorded and analyzed.Results:All patients were followed up for 6 to 36 months (average, 13.5 months). Failed anterior ring fixation was observed in 7 cases (8.3%) at 3 to 75 days after operation (average, 29.1 days). The failure was attributed to improper operation timing and unstable anterior ring fixation in 2 cases, mere unstable anterior ring fixation in one, wrong choice of anterior ring fixators and improper rehabilitation in 2 cases, poor intraoperative reduction in one and unstable posterior ring fixation in one. In the 2 failed cases that had been treated by external fixators, one underwent revision and the other conservative treatment. In the 5 cases that had been treated by plating, 4 underwent revision and one conservative treatment. By the Majeed criteria, the pelvic function was evaluated at the final follow-up as excellent in 2, good in 2 and fair in one in the 5 cases of revision who obtained follow-up from 11 to 24 months(average, 17.2 months) after revision; malunion was observed in the 2 cases of conservative treatment.Conclusions:Failed anterior ring fixation for unstable pelvic fracture may be caused by improper operation timing, wrong choice of anterior ring fixators, intraoperative malreduction, unstable pelvic ring fixation and improper rehabilitation. The key solution to failed anterior ring fixation is to find the specific causes. Plate revision may lead to fine therapeutic efficacy.

ABSTRACT

Objective To explore the effect of the proximal femoral nail antirotation(PFNa) for the treatment of femoral intertrochanteric fracture.Methods 272 consecutive patients with femoral intertrochanteric fracture were treated with PFNa.Results The mean operative time was 55min(range 35 ~95)min.The mean blood loss was 85ml (range:20 ~200)ml.The mean follow-up was 15.6months( range:6 ~36)monthsand achieved bone healing with an average time of 14.5weeks.According to the Harris criterion for evaluation.Conclusion PFNa was more comfortable for human's biomechanism and more favorable for the healing of the fracture as well as the recovery of the hip function.It had the advantage of simple manipulation,fewer trauma,strong fixation,anti-rotation,less osclerotin.PFNa was an ideal treatment for intertrochanteric fracture,specially the unstable intertrochanteric fracture and senile osteoporosis.

ABSTRACT

Objective To investigate the risk factors related to failure of proximal femoral nail anti-rotation(PFNA)internal fixation for intertrochanteric fracture of femur.Methods A retrospective research was done on 249 cases with intertrochanteric fracture of femur after PFNA internal fixation.The failure ratios related to sex,fat,fracture pattern,osteoporosis,replace condition in operation and tip-apex distance(TAD)were calculated.And the risk factors related to failure of PFNA were statistically analysed.Results Two hundred and forty-three cases were followed up ranged from 10 months to 3 years after operation.Plain AP and lateral radiographs were obtained at each follow-up patient,13 of 243 cases resulted in failing by PFNA internal fixation.The failure ratios in PFNA internal fixation with fat,unstable fracture,TAD≥25 mm and bad replace condition in operation were 8.5%(12/141),7.8%(12/153),18.5 %(5/27)and 26.1%(6/23),respectively,which were higher than those in PFNA internal fixation with nonobese,stable fracture,TAD < 25 mm and good replace condition in operation[1.0%(1/102),1.1%(1/90),3.7%(8/216)and 3.2%(7/220),respectively](P<0.05 or <0.01).Conclusions Fat,unstable fracture,TAD≥25 mm and bad replace condition in operation are the relatively independent risk factors related to failure of PFNA internal fixation for intertrochanteric fracture of femur.Furthermore,it will prevent and reduce the ratio of complications to avoid these risk factors when PFNA internal fixation is selected for treatment intertrochanteric fracture of femur.

ABSTRACT

[Objective]To explore the operative treatment and clinical result of scapula fracture by reconstruction plate internal fixation.[Method]From August 2002 to November 2006 , 18 cases of scapula fracture were treated by open surgical operation with reconstruction plates through the straight incision along lateral border of the scapula. Ten cases were examined by three-dimensional CT reconstruction before operations. [Result]All the patients were followed up. The fracture healing time lasted for 8-12 weeks. According to Hardegger evaluation, 11 cases showed excellent results, 4 good, 2 fair, 1 poor. The excellent result was 83.3%.[Conclusion]Three-dimensional CT reconstruction is of guidable meaning in the diagnosis and treatment of scapula fracture. With strict operative guides, the reconstruction plate internal fixation for the operative treatment of scapula fracture could acquire the satisfactory clinical result.

ABSTRACT

Objective To explore the feasibility and clinical result in reconstructing of femoral artery defects with external jugular vein graft. Methods Sixteen cases of femoral artery defects caused by pseudoaneurgsm resected were reconstructed with external jugular vein graft from June 2002 to August 2005. Results The limbs of all the patients were salvaged successfully.Thirteen patients were followed up from 1 to 24 months. Their dorsal arteries of foot pulsated well, and there was no pseudoaneurgsm broken or defect recurred. Femoral nerve injury was found in one case. Femoral artery continuity was detected under the color ultrasound Doppler in 6 cases. Conclusion Reconstructing of femoral artery defects with external jugular vein graft is feasible, the effect of which is sure. The shortcoming is that the scar on the neck affects appearance after resect of external jugular vein.
