OBJECTIVETo compare the clinical efficacy on the motor impairment of knee joint after tracture operation between the combined therapeutic method of relaxing needling manipulation and exercise therapy and the simple exercise therapy.

METHODSSixty-four patients after the operation for the fracture of femoral shaft were randomized into a relaxing needling combined with exercise therapy group (group A) and an exercise therapy group (group B), 32 cases in each one. In the group A, the relaxing needling manipulation was applied to the local painful area of knee or the stiff soft tissues. Additionally, the exercise therapy was used in combination. In the group B, the exercise therapy was applied simply. Hospital for special surgery (HSS) pain score, the range of movement (ROM) of knee joint and Lysholm score were compared before and 60 days after treatment in the patients of the two groups. The efficacy was compared between the two groups.

RESULTSAfter treatment, HSS pain score, ROM and Lysholm score were all improved in the two groups, presenting the significant differences as compared with those before treatment (all P<0. 05). The results in the group A were better than those in the group B (all P<0. 05). The total effective rate was 96. 9% (31/32) in the group A, which was better than 75. 0% (24/32) in the group B (P<0. 05).

CONCLUSIONThe combined therapeutic method of relaxing needling manipulation and exercise therapy achieves the significant efficacy on the motor impairment of knee joint after the operation for the fracture of femoral shaft, superior to the simple exercise therapy.

Objective To analyze the clinical and radiographic characterstics of ureteral polyps with hydronephrosis in children.Methods Thirteen patients with ureteral polyps and hydronephrosis were studied retrospectively.All patients underwent abdominal plain film,intravenous pyelogram(IVP)and ultrasound(US)examinations,contrast-enhanced CT scan was performed in 10 cases.Results Intermittent or recurrent abdominal pain with painless hematuria was presented in most cases.Hydronephrosis was demonstrated in radiographic images.IVP delineated the dilatation of the ureter and filling defects within the ureteral lumen in 5 cases.Computed tomography(CT)showed all abnormal changes of ureter and irregular intraluminal soft tissue masses in 6 cases.Moderate and low echoic structures were showed in ureters by US in 2 cases.Conclusion US and CT,as an important imaging modalities,can improve the diagnostic accuracy for ureteral polyps.

OBJECTIVETo discuss the clinical effect of closed reduction and interlocking intramedullary nailing in the treatment of femoral shaft fracture.

METHODSFrom March 2006 to December 2011,103 patients with femoral shaft fracture were treated by closed reduction and interlocking intramedullary nailing including 76 males and 27 females with an average age of 36 years old ranging from 19 to 55 years old. According to AO classification,there were 64 cases with type A,27 with type B, 12 with type C. Thirteen cases were open fractures including 5 cases with Gustilo type I , 8 with Gustilo type II . The time of bone healing were observed after operation, the knee function recovery was evaluated by HSS scoring standard at 1 year after operation.

RESULTSThe intraoperative complications included femoral neck fracture in 1 case and proximal femoral fracture in 1 case,both of the patients were treated with reconstructive intramedullary interlocking nail and the fractures healed postoperatively. One patient was suffered from common peroneal nerve injury,which were fully recovered at 4 months later after medical treatment. All the patients were followed up from 12 to 28 months (averaged 22 months). All of the fractures were healed well and the average healing time was 3 to 9 months (averaged 5 months). All the hip joints were recovered to normal function. The average HSS was 90.89±5.06 at 1 year after operation.

CONCLUSIONInterlocking intramedullary nailing is the preferred treatment for patients with femoral shaft fracture. Carefully operating and closed reduction can reduce the complications.

Background Congenital blepharoptosis is a common disorder of eyelid movement.Overseas research showed that the most likely mechanism of congenital blepharoptosis is the hypoplasia of levator.But the study on Chinese is still lack.Objective This study was to investigate the pathological features of hypoplasia in levator aponeurosis in Chinese congenital blepharoptosis patients.Methods Twenty-one patients with congenital blepharoptosis were divided into mild group (3 cases),moderate group (14 cases) and severe group (4 cases).Samples of the levator aponeurosis were obtained during the levator palpebrae superioris muscle shortening surgery.Hematoxylin-eosin,special staining and immunohistochemistry were performed to analyze the characteristics of the samples.Normal samples of fresh levator aponeurosis were obtained from the donors in the eye bank of Beijign Tongren Hospital.Results Hematoxylin-eosin staining and special staining showed that with the increase of severity,the cases of levator fibers sparse,fibrous tissue hyperplasia and endomysium defect were gradually increased,showing significant differences among the different groups (Z =-0.702,P =0.002 ; Z =0.738,P ＜ 0.001 ; Z =0.746,P ＜ 0.001).Four samples (19％) presented with adipose in the interstitial tissue.Immunohistochemistry showed that the expression of muscle proteins myosin was weaker in the levator aponeurosis of patients with congenital blepharoptosis than that in the normal samples,and the expression intensity of collagen type Ⅲ in the samples enhanced in comparison with the normal samples.However,there were no significant differences in the expression of actin,myoglobin,fibronection,collagen type Ⅵ and laminin among various groups (all at P＞0.05).Conclusions The levator aponeurosis appears developing abnormality in Chinese patients with congenital blepharoptosis.The histopathological change degree is parallel with the severity of congenital blepharoptosis.

Objective To evaluate the value of differential diagnosis on congenital biliary atresia(BA) and infantile hepatitis syndrome(IHS) by technetium-99m-diethyl-iminodiacetic acid(99Tcm-EHIDA)hepatobiliary scintigraphy with phenobarbitol sodium.Methods Fifty-eight infants with persistent jaundice were taken phenobarbitol sodium[5 mg/(kg?d)] ,bid ?7 d).Those who had not bowel and gallbladders radioactivity within 24 hours were diagnosed as the diagnostic criterion of BA.Those with bowel and gallbladders radioactivity within 24 hours were diagnosed as the diagnostic criterion of IHS,who then received 99Tcm-EHIDA hepatobiliary scintigraphy with single photon emission computed tomography(SPECT) instrument.The results of all children were analyzed and compared with pathology and clinical follow up results.Results 99Tcm-EHIDA hepatobiliary scintigraphy correctly diagnosed 24 infants with last diagnosis BA and 29 infants with last diagnosis IHS,5 neonates false positive in all 34 IHS patients.The sensitivity in the diagnosis of BA was 100%,the specificity and accuracy were 85.3% and 91.4%,restectively.The sensitivity was 85.3% in the diagnosis of IHS;the specificity and accuracy were 100% and 91.4%,respectively.Conclusions 99Tcm-EHIDA hepatobiliary scintigraphy with phenobarbitol sodium can accurately differentiate BA and HIS at early stage.

Objective To investigate the clinical characteristics of posterior malleolar ankle fracture, and the selection of the surgical approach. Methods From January 2013 to September 2015, 83 cases of posterior malleolar fractures were retrospectively analyzed. Haraguchi typing was performed based on the three-dimensional CT. There were 54 cases with HaraguchiⅠtype, 16 cases with HaraguchiⅡtype, and 13 cases with HaraguchiⅢtype. The patients who were HaraguchiⅠand Haraguchi Ⅲtypes accepted the operation with posterolateral approach. The patients who were HaraguchiⅡtype and combined medial malleolus fracture accepted the operation with medial approach. The HaraguchiⅡpatients who were not combined medial malleolus fracture were used the medial paraachilles approach. Images of the ankle joint were filmed 2 weeks, 4 weeks, 12 weeks, 6 months and 12 months after the surgery. The healing time, complications and corresponding record outcome were determined by X-ray and clinical examination. At the last follow-up, ankle function and quality of life of patients were evaluated according to the American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score and SF-36. Results Eighty-three patients were follow-up for 6-24 (mean 15.4± 6.2) months. The fractures healed on X-ray. The average X-ray healing time was from 12 to 24 (mean 18.6±4.2) weeks. AOFAS score was 71 to 100 (mean 88.4±8.4) points. Sixty-seven cases were excellent, 14 cases were good, 2 cases were moderate, and good rate was 97.59%. SF-36 physiological score was 31.6-69.2 points(mean 48.4 ± 4.8 points);SF-36 psychological score 28.6-64.5 points(mean 45.8 ± 3.5 points). Chronic ankle pain was complained by one patient. He was diagnosed traumatic arthritis, oral non-steroidal drugs was used to relief his ankle pain. One patient wound infected, and healed after treatment. No instrument failure and fracture displacement were found. Conclusion According to fracture morphology and clinical features after posterior malleolar ankle fracture, different surgical approaches are selected, which will be satisfied with the outcome.

OBJECTIVETo explore early clinical effect of acetabular cup in total hip replacement for the treatment of Crowe II developmental dysplasia of hip.

METHODSEighteen patients (18 hips) with Crowe type II developmental dysplasia of hip were treated with total hip replacement from September 2001 to July 2013. Among them,including 13 males and 5 females aged from 42 to 60 years old with an average of 47.6 years old; the courses of diseases ranged from 9 to 22 years with an average of 13.5 years. All the patients had hip joint pain, limb shortening and limited hip function before operation. Harris score of hip joint were used to evaluate recovery of function at 1 day and 12 months after operation. Prosthetic coverage of acetabular cup at 1 week after operation was observed by using radiography.

RESULTSEighteen patients (18 hips) were followed up from 12 to 24 months with an average 17 months. All incisions were healed at stage I. No deep vein thrombosis, hip dislocation, periprosthetic joint infection and prosthesis loosening were occurred. No revision surgery during follow-up period. Prosthetic coverage of acetabular cup was more than 80% at 1 week after operation. Harris score were increased from 42.67 ± 5.06 before operation to 94.79 ± 3.27 at 12 months after operation (t = -45.269, P < 0.001).

CONCLUSIONFor type Crowe II developmental dysplasia of hip patients, 15° face-changing acetabular cups in THR could obtain higher actebular component coverage rate and satisfactory early clinical effects.
