OBJECTIVETo study the clinical efficacy of semiextended intramedullary nailing of the tibia using a suprapatellar approach for proximal tibial fractures.

METHODSFrom January 2013 to January 2014, a total of 16 patients with unilateral proximal tibial fractures, 14 males and 2 females, underwent closed reduction and internal fixation with TRIGEN™ META-NAIL™ via the suprapatellar approach. The average age was 42.2 years old (ranged, 26 to 57 years old). Radiographic and clinical follow-up examinations were performed at a minimum of 1 year after surgery. Measurements included surgery time, complications, bone healing time, tibial alignment, knee range of motion, pain scoring (visual analogue scale) and functional outcome (Lysholm knee score).

RESULTSThe average surgery time was (75.7±8.3) minutes (ranged, 65 to 95 minutes). No obvious complications were recorded. Average duration of follow-up was (15.6±8.1) months (ranged, 12 to 24 months). Fifteen patients attained radiological bone union for a mean time of (3.6±1.8) months (ranged, 3 to 5 months). At the final follow-up, all tibial alignments were good, and no patients complained of anterior knee pain. Mean arc of knee motion was (124.4±18.8) degrees for the affected extremity compared with (127.5±16.7) degrees for the contra-lateral knee. The total scores of Lysholm knee score ranged from 77 to 92, average 86.4±12.3.

CONCLUSIONFor proximal tibial fractures,the semiextended intramedullary nailing technique via a suprapatellar approach can obtain satisfactory clinical outcomes with simplicity in reduction and fixation, minimal complications, and good recovery of limbs function.

Objective To report the clinical results of minimally invasive percutaneous plate osteosynthesis (MIPPO) in treatment of type C fractures of distal femur.Methods A retrospective study was conducted to an- alyze 14 consecutive cases of distal femoral fractures who had been treated with MIPPO in our department from April 2002 to February 2005.According to AO/ASIF classification,there were three cases of type C1,six cases of type C2,and five cases of type C3.At first,the fractures of articular surface were directly reduced and fixed with spongy screws.Next,the condylar fractures were indirectly reduced and fixed with buttress or LISS (less invasive stabi- lization system) plates through transarticular approach.Results Follow-ups,ranging from 10 to 32 months for 12 cases,revealed that they all reached union.The time for their bony union was 10 weeks to 12 months (mean,4.6 months).Their functional recovery was evaluated according to criteria by Kolmert and Wulff.Four cases were rated as excellent,five as good,two as fair and one as poor.The total satisfactory rate was 75%.Conclusion MIPPO is a safe and effective procedure for the type C fractures of the distal femur with the benefits of limited invasion to soft tissues and a high rate of bone union.

OBJECTIVE To investigate the expression of PTEN and VEGF gene in laryngeal squamous cell carcinoma and their clinical significance. METHODS The expression of PTEN and VEGF gene were examined by using immunohistochemical S-P staining method in 10 cases of normal tissues, 20 cases of para-tumor tissues and 60 cases of LSCC. RESULTS The positive rates of PTEN in normal tissues, para-tumor tissues and LSCC were 100.0 %, 95.0 %, and 70.0 % respectively (P＜0.05),and VEGF protein showed positive expression of 20.0 %,50.0 %,73.3% in normal, para-tumor and LSCC tissues with statistical significance(P＜0.05), In LSCC, the expression of PTEN and VEGF was positively correlated with TNM stage, differentiation of tumor, cervical and distant metastasis of lymph node, 3-year survive rate of patients(P＜0.05),No significant association was observed in expression of PTEN and VEGF with tumor location,patient's age and sex(P＞0.05). Spearman correlation analysis revealed that PTEN was negatively correlated with VEGF expression(?=-0.3948, P=0.0018). CONCLUSION The aberrant expression of PTEN and VEGF may play a role in occurrence, progression and metastasis of LSCC.

OBJECTIVETo evaluate preoperative application of recombinant human erythropoietin (rHuEPO) in reducing transfusion requirements in elderly patients undergoing elective surgery for femoral intertrochanteric fractures.

METHODSFrom January 2011 to December 2013,442 cases of elderly patients with femoral intertrochanteric fracture were retrospectively reviewed. According to inclusion and exclusion criteria, 119 cases were eventually included and divided into the treatment group and the control group. There were 12 males and 40 females, with a mean age (71.4 ± 12.8) years old, and the patients received preoperative administration of rHuEPO 10,000 U qod combined with iron dextran 200 mg (3 times each day). While 16 males and 51 females in control group, with a mean age (70.9 ± 16.2) years old, and the patients only received preoperative administration of iron dextran 200 mg (3 times each day). All the patients received closed reduction and PFNA-II or Internal fixation surgeries. The perioperative blood transfusion rate, average amount of blood transfusion, postoperative complications, the length of hospital stay and mortality within 30 days were compared between the two groups.

RESULTSThere were no statistical differences between two groups in the baseline indexes (P > 0.05). Overall,71 of 119 patients (59.7%) received at least one unit allogeneic blood transfusion (ABT). However,there were significant differences in perioperative ABT rates (48.1% vs 68.7%, χ2 = 4.77, P < 0.05) and the average amount of blood transfusion between treatment group and control group, which were (1.8 ± 0.4) U/pte vs (3.6 ± 1.1) U/pte (t = 2.244, P < 0.05). Postoperative hemoglobin (Hb) on postoperative days 7 and 30 was higher in treatment group than that in control group. In addition, in treatment group, Hb levels were higher on postoperative day 30 than those on admission, which were (128.2 ± 20.6) g/L vs (118.2 ± 18.9) g/L (t = 2.133, P < 0.05). There were no statistical differences in postoperative complications, the length of hospital stay and mortality within 30 days.

CONCLUSIONFor elderly patients with femoral intertrochanteric fractures undergoing elective surgery, preoperative application of rHuEPO can significantly reduce perioperative transfusion requirements, and is likely to reduce ABT-related infection, but its long-term safety remains to be evaluated.

OBJECTIVETo observe the clinical effectiveness of Sanmiao Powder (SP) combined fibrinogenase for injection in treatment of acute deep venous thrombosis (ADVT) of lower limbs.

METHODSEighty patients with ADVT were randomly assigned to two groups according to the disease course (within 7 days or 7-28 days), 40 in each group. Every time phase was also divided into two groups, i. e., one group treated with fibrinogenase for injection alone (Group A and C) and another group treated with fibrinogenase for injection + SP administration (Group B and D) , 20 in each group. The clinical effectiveness was observed after 2-week treatment.

RESULTSThe fibrinogenase for injection + SP administration showed better effects in alleviating the swelling of limbs, relieving pain, and lowering fibrinogen. Better effects were obtained in the group with the disease course less than 7 days.

CONCLUSIONBetter effect on ADVT was obtained by integrative medicine.

ObjectiveTo study the MR Imaging features of breast phyllodes tumor (PT),and to correlate it with pathological results.MethodClinical and MRI findings were retrospectively reviewed in twenty-seven women with 28 PTs lesions confirmed by surgical pathology.Statistical analyses were one-way ANOVA for size analysis,Fisher exact test for analysis of MR appearances and Spearman correlation to study the relationship between MRI findings and BI-RADS categories.Results( 1 ) The histologic findings were benign,borderline and malignant PTs in 14.3％ (4/28),53.6％ (15/28) and 32.1％ (9/28) of lesions,respectively.(2) The mean maximum-diameter were (6.4 ± 3.9) cm,(5.7 ± 2.2) cm in borderline type and (4.8 ± 1.8)cm in benign type respectively.The results showed differences in lesion's size among the three type (F = 287.541,P =0.000),especially between malignant and benign type (P = 0.033 ).(3)Internal non-enhanced septations and silt-like changes on enhanced images,as well as time-signal curve on MRI correlated significantly with the histological grade ( P ＜ 0.05 ).( 4 ) If the category BI-RADS ≥ 4a was considered to be a suspicious sign for malignant lesion,the diagnostic accuracy of MRI would be 96.4％ (27/28),and the BI-RADS category of the MRI could reflect the PT's histological grade with a low correlation coefficient ( r = 0.382,P = 0.045 ).Conclusion The findings of PT on MRI have some characteristics,with tumor size and several MRI features correlating with the histological grade of breast PT.

OBJECTIVETo investigate the early clinical efficacy of induced membrane technique for reconstruction of large bone defects after debridement in adults with chronic osteomyelitis of limbs.

METHODSFrom March 2010 to March 2012,a total of 23 adult patients with chronic osteomyelitis of limbs were treated in our department. There were 15 males and 8 females, with a mean age 35.2 years old (ranged from 26 to 49 years old). Sixteen patients had open fracture history. According to the lesion site, there were 12 cases of tibia, 7 cases of femur, 3 cases of humerus, and 1 case of both radius and ulna. Among them, 19 patients had diseases in diaphysis and 4 patients in the metaphysis. The mean interval from infection to operation was 6.9 months (ranged from 4 to 13 months). All the patients were treated by using induced membrane technique. The follow-up evaluation included clinical complications, time of bone healing and limbs function. The Chinese version of SF-36 scores was used in the assessment of quality of life pre- and post-operation.

RESULTSThe average duration of follow-up was (27.6 ± 5.3) months (ranged from 18 to 43 months). Two patients had postoperative flap edge necrosis, 1 patient had superficial iliac incision infection, no obvious complications were recorded. Twenty patients obtained radiological union at a mean time of 4.6 months (ranged from 3 to 7 months). Among them, 16 patients treated with lower limbs surgery achieved full weight-bearing at about 5.2 months (ranged from 4 to 8 months) postoperatively. Four patients suffered from reinfection during follow-up, but 3 of them achieved complete bone healing after the second surgeries with induced membrane technique. At the final follow-up, there was a substantial improvement in each dimension scores and total scores of SF-36 as compared with those before surgery.

CONCLUSIONWhen treating with adult chronic osteomyelitis of limbs, the induced membrane technique can effectively reconstruct large bone defects after debridement, significantly shorten treatment cycle, provide satisfactory results with minimal complications, promote good recovery of limbs function and require relatively simple operation technique.

OBJECTIVETo evaluate the clinical outcome of accessory navicular fusion for treatment of the painful accessory navicular bone of type II in adults.

METHODSFrom June 2006 to June 2012, a total of 38 feet (in 35 adult patients) with painful accessory navicular with type I underwent an fusion operation of the primary and accessory navicular bones,including 26 males and 9 females with a mean age of (32.4±7.3) years old ranging from 18 to 44 years old. The course of disease ranged from 3 to 10 months. The perioperative complications and radiological outcomes were observed and recorded. The foot function before and after operation were assessed by the American Orthopedic Foot and Ankle Society (AOFAS) midfoot score, and the easement of the pain was evaluated by visual analog score (VAS).

RESULTSTwo patients had transient superficial inflammation of the incision, no obvious perioperative complications occurred. All patients were follow-up for (53.5±14.7) months (12 to 84 months). Bone union was confirmed on plain radiography in 32 cases (35 feet). The mean time from the operation to union was (13.7±2.3) weeks (9 to 18 weeks). Postoperative pain VAS score was improved obviosly than preoperative (V=12.14,P< 0.01). The talar-to-first metatarsal angle [(9.4±3.5)° vs (8.3±2.7)°, t=0.736, P>0.05)], calcaneal tilt angle [(17.7±2.2)° vs (18.9±3.4)°, t=0.794, P>0.05],talonavicular uncoverage angle [(14.3±3.4)° vs(12.5?4.6)°,t=0.947, P>0.05) ],and height of the first tarsometatarsal joint [(14.8±3.1) mm vs (15.9±2.8) mm,t=0.814,P>0.05)] before and after operations had no statistic difference. The AOFAS midfoot score was improced from preoperative 45.6±5.3 to postoperative 82.5±7.4 (t=3.214,P< 0.01).

CONCLUSIONFor the painful accessory navicular bone of type II in adults, if the patient has a large navicular bone and not complicated with rigid flatfoot, once the conservative treatment fails, fusion of the primary and accessory naviculars may be a successful intervention. Overall, the procedure provides reliable pain relief, definite foot function improvement, and good patient satisfaction.

OBJECTIVETo evaluate the early clinical and radiographic outcome of scaphoid non-unions treated with Acutrak headless compression screw.

METHODSFrom January 2008 to July 2011,21 patients with scaphoid non-union were treated in our department. There were 18 males and 3 females with a mean age of (23.6 +/- 4.6) years; 12 cases were on right hand and 9 were on left. According to Herbert-Fisher classification, there were 10 cases with type D1, 7 cases with type D2, 3 cases with type D3, and 1 case with type D4. The mean time from injury to operation was (12.4 +/- 2.7) months. All patients were treated with Acutrak headless compression screw fixation (6 cases received 2 screws fixation, 15 cases received 1 screw fixation, and Matti-Russe bone grafting was applied in 7 cases). The carpal height, the scaphoid index and changes of the scapholunate angle were assessed before and after the operation. Range of motion and grip strength were recorded and the wrist function was assessed according to the Patient-Rated Wrist Evaluation (PRWE).

RESULTSAverage duration of follow-up was (21.3 +/- 3.6) months. All the patients attained radiological union in a mean time of (13.3 +/- 2.4) weeks following the operation. No obvious complications were recorded. The surgical treatment allowed the preoperative mean scaphoid index of 0.61 +/- 0.13 and the preoperative mean scapholunate angle of (59.4 +/- 6.8) degree to be improved to 0.69 +/- 0.10 and (44.3 +/- 8.2)degree postoperatively, respectively. There was a substantial improvement in grip strength and pain amelioration after surgery. The preoperative mean PRWE score of 45.2 +/- 4.7 was improved to 76.1 +/- 5.2 postoperatively. All patients returned back to the original work,the average time from surgery to work was (6.0 +/- 1.1) months.

CONCLUSIONFor scaphoid non-unions, Acutrak headless compression screw fixation can provide anatomical reduction, provide satisfactory results with a high union rate, well return of function and minimal complications in the early stage.
