Methods From January 2007 to December 2009, 56 patients with complex tibial plateau fractures underwent open reduction and internal fixation. The patients included 37 males and 19 females with the age of 19-76 years old (average 45.6 years old). The Schatzker type of the fractures were type Ⅳ in 12 patients, type Ⅴ in 26, and type Ⅵ in 18. The injuries included meniscus injury in 20 patients, injury of lateral collateral ligament of knee in 9, injury of lateral collateral ligament in 8, and cruciate ligaments injury in 4. The time duration between the injury and the surgery was 7-14 days (average 9 days). Results After the surgery, the incision healed at I stage in 53 patients. The incision was superficially infected 3 days after surgery in 2 patients, and the Necrosis of skin around the incision and revealed steel plate were found 7 days after surgery in 1 patient; the injuries was healed after corresponding treatment. All of the patients were followed up with the average follow-up period of 14-49 months (average 19 months). The fractures healed 4-8 weeks (average 6 weeks) after the surgery. Knee joint ankylosis was found in one, traumatic arthritis was found in two, and heterotopic ossification was found in one; the injuries was healed after corresponding treatment. Twelve months after the surgery, the therapeutic effect according to HSS criteria indicated that the score was excellent in 43, good in 5, generally in 4 and poor in 4; with a fine rate of 85.7%. Conclusion Appropriate conditions of the soft tissue, good surgical opportunity, a appropriate fixation, improved surgical technique and effective postoperative functional training are the key points of surgical treatment for complex tibial plateau fractures.
ObjectiveTo compare the short-term effectiveness of one-stage posterior debridement with non-structural bone graft and structural bone graft in the treatment of single segment thoracic tuberculosis.MethodsThe data of 61 patients with single segment thoracic tuberculosis, who were treated by one-stage posterior debridement, bone graft fusion, and internal fixation between June 2011 and August 2015, was retrospectively analyzed. All of them, 26 cases were treated with structural bone graft (group A) and 35 cases with non-structural bone graft (group B). No significant difference was found between the two groups in gender, age, disease duration, comorbidity, involved segments, paravertebral abscess, and preoperative American Spinal Injury Association (ASIA) grade, C reactive protein (CRP), visual analogue scale (VAS) score, and Cobb angle of involved segments (P>0.05). But the preoperative erythrocyte sedimentation rate (ESR) in group B was significantly lower than that in group A (t=3.128, P=0.003). The operation time, intraoperative blood loss, hospitalization stay, VAS score, ESR, CRP, ASIA grade, postoperative complications, Cobb angle of involved segments and its correction rate and loss rate, and bone fusion time were recorded and compared between the two groups.ResultsCompared with group A, group B had shorter operation time, less intraoperative blood loss, and longer hospitalization stay, showing significant differences (P<0.05). The follow-up time of group A was (36.3±10.0) months, which was significantly longer than that of group B [(18.4±4.2) months] (t=10.722, P=0.000). At last follow-up, the VAS score, ESR, and CRP in the two groups all significantly improved when compared with those before operation (P<0.05); the CRP of group B was significantly higher than that of group A (t=–2.947, P=0.005); but there was no significant difference in ESR and VAS score between the two groups (P>0.05). At last follow-up, the ASIA grade of the two groups significantly improved when compared with those before operation, and there was no significant difference between the two groups (Z=–1.104, P=0.270). There were 9 cases and 10 cases of complications in groups A and B, respectively, and there was no significant difference (χ2=0.254, P=0.614). The Cobb angle in group B was significantly higher than that in group A at 3 days after operation (t=–2.861, P=0.006), but there was no significant difference in Cobb angle between the two groups at last follow-up (t=–1.212, P=0.230). The postoperative correction rate and loss rate of Cobb angle in group A were higher than those in group B, and there was a significant difference in the loss rate between the two groups (t=2.261, P=0.031). All patients got bone graft fusion and the bone fusion time of group B was significantly shorter than that of group A (t=4.824, P=0.000).ConclusionNon-structural and structural bone graft can both achieve good effectiveness in the treatment of single segment thoracic tuberculosis, but the former has the advantages of less surgical trauma and shorter fusion time.
Objective To measure the included angle between tibia anatomical axis and anterior cortex, and to define the relative position of them in order to give direction in placement of tibia extra-medullary alignment bar during total knee arthroplasty. Methods A total of 100 healthy volunteers were included (49 left knees and 51 right knees). There were 52 males and 48 females, aged 20-86 years with an average age of 45.2 years (20-35 years in 29 cases, 35-50 years in 32 cases, and over 50 years in 39 cases). The tibiofibular lateral X-ray films were taken to measure the included angle between tibia anatomical axis and anterior cortex with AutoCAD2004 system. The samples were grouped according to gender, age, and side. Results The included angles between tibia anatomical axis and anterior cortex ranged from 3.007 to 3.021° with an average of 3.001°; the angles were (2.965 ± 0.361)° in male and (3.041 ± 0.311)° in female; the angles were (2.996 ± 0.332)° in the left knee and (3.006 ± 0.347)° in the right knee; and the angles were (2.918 ± 0.346)° in 20-35 years age group, (3.060 ± 0.330)° in 35-50 years age group, and (3.014 ± 0.336)° in over 50 years age group. No significant difference was found in the included angle between tibia anatomical axis and anterior cortex between male and female, among different ages, and between left and right knees (P gt; 0.05). Conclusion The included angle between tibia anatomical axis and anterior cortex is about 3°, so tibia extra-medullary alignment bar should be placed at the angle of 3° with anterior cortex during total knee arthroplasty.
Objective To investigate the treatment method of senile patients with femoral intertrochanteric fractures and its cl inical outcomes. Methods From January 2005 to December 2007, 192 senile patients with femoral intertrochanteric fractures were treated, including 85 males and 107 females aged 65-92 years old (average 75 years old). The injury was causedby fall on walking in 106 cases, fall when riding a bicycle in 55 cases, and traffic accidents in 31 cases. According to Evans classification, there were 12 cases of type I A, 43 cases of type I B, 29 cases of type II, 24 cases of type III A, 23 cases of type III B, 26 cases of type IV, and 35 cases of type V. One hundred and fifty patients were associated with cardio-cerebrovascular diseases, 120 patients were compl icated with chronicle hypertension, 90 cases were associated with bronchitis, and 75 cases were compl icated with diabetes. The time from injury to hospital admission was 1 hour to 14 days. Among those patients, 108 were treated with conservative treatment, 68 received dynamic hip screw (DHS) fixation, and 16 underwent proximal femoral Gamma nail fixation. Results All the patients were followed up for 12-36 months (average 18 months). The fracture all reached bone union without occurrence of nonunion and delayed union. Patients could take care of themselves, and there were no occurrences of serious pains and dysfunctions. The therapeutic effect was satisfactory. The conservative treatment group: the average hospital stay length was 48 days; the average bone heal ing time was 14 weeks; 23 cases had different degrees of coxa adducta; Harris score system was adopted to evaluate hip joint function, 45 cases were graded as excellent, 31 as good, 10 as fair, and 22 as poor, and the excellent and good rate was 70.4%. DHS internal fixation group: the average operation time was 60 minutes; the average bleeding volume during operation was 200 mL, the average hospital stay length was 24 days; the average bone heal ing time after operation was 12 weeks; Harris score system was adopted to evaluate the injured hip joint function, 38 cases were graded as excellent, 21 as good, 8 as fair, and 1 as poor, and the excellent and good rate was 86.8%. Gamma nailfixation group: the average operation time was 70 minutes; the average bleeding volume during operation was 200 mL, the average hospital stay length was 14 days; the average bone heal ing time after operation was 12 weeks; Harris score system was adopted to evaluate the injured hip joint function, 11 cases were graded as excellent, 4 as good, 1 as fair, and the excellent and good rate was 93.8%. Conclusion For geriatric femoral intertrochanteric fractures, operative treatment should be performed, the preoperative preparation should be sufficient, and individual-oriented treatment method should be selected on the basis of physical conditions of patients and the types of fractures.
