RESUMO
Objective To explore the feasibility and curative effect of arthroscopic treatment of avulsion fracture of the tibial attachment of anterior cruciate ligament ( ACL ) using Ethibood line plus double Endobutton plates. Methods From May 2014 to January 2016, 26 cases of acute ACL tibial attachment fracture were treated surgically. They were 16 males and 10 females, aged from 9 to 45 years ( average, 26. 6 years ) . By the Meyers-McKeeve classification, there were 17 cases of type Ⅱand 9 ones of type Ⅲ. In preoperative examina-tion, their Lachman test and Anterior Drawer Test were all positive. All their bone blocks were fixated using Ethibond line plus double Endobutton plates. Results Their operative time ranged from 50 to 70 min, averaging 57 min. On average, the 26 patients obtained a follow-up of 8 months ( from 6 to 13 months ) . X-rays at 3 months after operation showed all fractures united. At the last follow-up, their Lachman test and Anterior Drawer Test were all negative. The range of motion of the knee joint was larger than 120° in all; their Lysholm score of the knee joint averaged 90. 6 ± 2. 9 points, significantly higher than their preoperative value ( 43. 6 ± 4. 7 points ) ( t=7. 583, P=0. 026 ); their International Knee Documentation Committee ( IKDC ) scores averaged 93. 1 ± 4. 2 points, significantly higher than their preoperative value ( 46. 3 ± 5. 1 points ) ( t=8. 162, P=0. 021 ) . No such complications as reflexive neural dystrophy, avascular necrosis or weak knee extension occurred during follow-ups. Conclusion The avulsion fractures of ACL tibial attachment can be treated arthroscop-ically using Ethibood line plus double Endobutton plates, because this technique has such advantages as simple operation, limited invasion, good fracture reduction, strong fixation, and possibility of early functional rehabil-itation of the knee joint.
RESUMO
Objective To compare DHS(dynamic hip screw )with PFNA(proximal femoral nail antirotation) treatment for intertrochanteric fractures and to analyze their postoperative complications .Methods A total of 107 patients with inter-trochanteric fractures were treated with DHS and PFNA fixation respectively .The type of fracture , postoperative complica-tions and overall efficacy were compared .Results After the follow-up of 28(24 to 36) months.DHS group had a higher overall incidence of postoperative complications than the PFNA group and the difference was statistically significant ( P<0.05).Conclusion In order to reduce the intertrochanteric fracture fixation complications , the type of fracture, osteoporo-sis and biomechanical fixation characteristics need to be considered when selecting surgical procedures .Postoperative func-tional rehabilitation is to be improved .The curative effect of PFNA is better than that of DHS .
RESUMO
Objective To evaluate the foot function after Lisfranc injury with local soft tissue in-jury. Methods From November 2000 to April 2006, 43 patients (at mean age of 32 years) with fresh Lisfranc injuries (45 sides) were managed with open reduction and internal fixation with screws, Kir-schner wires and AO plates. All patients had no joint surface damage and received no fusion surgery. Ac-cording to the Quenu-Kuss classification of Lisfranc injury, there were 14 patients with type-A injury, 21 with type-B and 10 with type-C. According to AO classification, there were 29 feet without severe soft tis-sue injury and 16 feet with severe soft tissue injury, of which 10 patients were combined with severe local soft tissue injury (one patient with Foot compartment syndrome). The period from injury to surgery was seven days. All patients received cast immobilization for 8-12 weeks and the foot function was evaluated by anteroposterior and lateral X-rays and American Orthopedic Foot and Ankle Society (AOFAS) score. Results All patients were followed up for 12-69 months (average 37 months), which showed that all pa-tients obtained anatomic reduction and 32 patients were satisfied with operative outcome. The average postoperative AOFAS score was 97 points for patients without severe soft tissue injury and 82 points for pa-tients with severe soft tissue injury (P<0.05). Conclusion After Lisfranc injury, the foot function is related to severity of both joint injury and local soft tissue injury.
RESUMO
Objective To explore the clinical curative effect of AF system combined vertebra re-duction and posterolateral bone fusion treatment thoracolumbar burst fracture .Methods Seventeen pa-tients with thoracolumbar burst fracture using period stage , according to the system of AF clinical symptoms and image data line pressure decreased , and the pressure or not to hurt inside the vertebral pedicle autoge-nous bone grafts are grain filling and vertebral posterolateral line between the axon , lamina around small joints and bone , and postoperative follow-up X-ray inspection regularly , observe internal fixation and verte-bral vertebral height and adjacent intervertebral space changes , or after fixation and reset lost .Results following up 13 months, vertebral body height restore and maintain good , bolt looseness and broken and ver-tebral body height complications such as lost were no found in 17 cases.Conclusion Treatments of Poste-rior fixation combined short stage AF vertebral body and posterolateral bone fusion on thoracolumbar burst fracture are not only rebuild the vertebral height , but also make the vertebral obtained after three pillars in stable, reduce the internal fixation and compressed vertebral again such complications .
