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 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.

Objective To analyze the correlation between clinical features and renal dysfunction in patients of acute lacunar infarction with progressive cerebral microbleeds (CMBs). Methods Two hundred and sixty-five patients with first-episode acute lacunar infarction were selected. The serum creatinine was measured within 24 h of admission and the estimated glomerular filtration rate (eGFR) was calculated. The brain MRI (including gradient-echo images) was examined within 2 d of admission and after 1 years of follow-up, respectively. The progressive CMBs was assessed with microbleeds anatomical rating scale (MARS), and the patients were divided into progressive CMBs group (progressive group, 42 cases) and non progressive CMBs group (non progressive group, 223 cases). The clinical features of 2 groups were compared and the correlation between progressive CMBs and renal dysfunction was analyzed. Results The age, 24 h pulse pressure, incidences of renal dysfunction and CMBs in progressive group were significantly higher than those in non progressive group: (69.8 ± 5.8) years vs. (61.5 ± 4.9) years, (63.3 ± 3.1) mmHg (1 mmHg=0.133 kPa) vs. (51.8 ± 4.2) mmHg, 69.0%(29/42) vs. 39.9%(89/223) and 57.1%(24/42) vs. 25.1%(56/223), and the platelet was significantly lower than that in non-progression group:(168 ± 35) ×109/L vs. (189 ± 40) ×109/L, and there were statistical differences (P<0.05 or<0.01). The Logistic regression analysis result showed that renal dysfunction and CMBs were Independent risk factors of progressive CMBs (OR = 1.571 and 1.054, 95% CI 1.042 - 2.493 and 1.010 - 1.142, P<0.05). Conclusions The rate of renal dysfunction is higher in patients of acute lacunar infarction with progressive CMBs, and progressive CMBs are associated with renal dysfunction.

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.

OBJECTIVETo analyse the diagnostic and therapeutic aspects of carotid body tumor (CBT).
METHODSSeven patients with CBT had been hospitalized between 2003 and 2006. The clinical data was analyzed retrospectively. The preoperative evaluation included angiography in 7 patients. Most of them had an asymptomatic cervical lateral mass. Only one patient had the hoarseness and buckling and was given radiation therapy alone. Six of seven patients with carotid body tumour underwent surgery. Simple tumor excision was accomplished in 4. Carotid artery resection with the tumor was required in 2 patients and in the both, interposition of a 7 mm polytetrafluoroethylene graft was performed . During the resection, temporary carotid shunt was required in the two patients.
RESULTSAll tumors by surgery were identified as carotid paragangliomas without evidence of malignancy. There was no mortality and no hemiplegia. After surgery, temporary cranial nerve dysfunction was noted in one case. In the follow-up period of 2 months to 2 years, no recurrent disease occurred. The patient's tumor who accepted radiotherapy was in the stable stage under the half year follow up, and the follow up would be further continued.
CONCLUSIONSWith non-invasive investigation and arteriography it was possible to obtain an early and precise diagnosis. The surgical management was the major treatment of these tumors. The pattern of operation should be chosen according to the relation of tumor and carotid. The decision to perform simple tumor excision or additional arterial resection was based on diagnostic preoperative and after the arterial resection the polytetrafluoroethylene graft would be used for carotid reconstruction.
