[Abstrct] Objective The deformity of severe varus knee (varus angulation > 15°) can be treated by many ways in primary total knee arthroplasty , but the efficacy and cost are different. The topic of this study provides a new surgery: autograft (wedge grafts) implant and substitute medial tibial bone defects. Methods From Jan. 2006 to Jan. 2014 , a retrospective study was conducted in the First Affiliated Hospital of BaoTou Mendical College. Out of 687 patients, 721 primary knees were operated. Bone defects in proximal tibia (varus angulation >15° ) were encounted in 16 patients in 21 knees in the pattern of non-inclusive slope bone defects in the mean varus degree of 27°. Their IBM was 31 kg/m2. The average age of patients was (63 ± 5) years. The score of clinical knee society score (KSS) before operation was 18 on average. Among of them, the pain score were 12 points, the average range of motion (ROM) were 12 points. the average funtional score were 20 points. During operation,the slope bone defect of the medial tibial plateau was tailored into wedge-shaped ladder bone defect by osteotomy,and then the defect was filled with the resected tibial plateau autograft in which the thickness and shape were matched completely. The high-intensity cortical part of the autograft was placed in the rim to sustain the tibial prosthesis. Three months after operation ,patients started to walk without the help of crutch. Results The average followup period was 5.3 y , We observed that an average postoperative scores of clinical KSS from 42 points to 88 points with the score of functional KSS from 57 points to 92 points. Fusion was observed by trabeculae crossing from the graft to the tibial metaphysis on plain films at least 6 mouths without collapse, stress fracture, untight and bone ununion. Confirmation of vascularization of the graft was observed in bone scans of nuclide. showing increased uptake in the operated area. Inflammatory makers were normal. Conclusion Autograft (wedge grafts) reconstruction of medial tibial bone defects, is of high rate of healing in implant bones, good restoration of the function and low cost.

Objective To investigate clinical service delivered at the Polyclinic of Beijing 2008 Olympic and Paralympic Village and outcomes of the medical patients visited there.to provide experiences in medical care service for other mass-gatherings in the future.Methads Clinical data of all the medical patients evaluated at the Polyclinic during July 27 to August 27 and during August 29 to September 19,2008 were reviewed retrospectively.with univariate and multivariate analyses.Results In total.1537 and 1206 medical patients visited the Polyclinic at the Olympic and Paralympic Village,respectively.Proportion of athletes visited was hisher during the Paralympic Games than that during the Olympic Games(14.2% vs.9.8%,P<0.01).We reeeived 775 patients(50.4%)with acute respiratory tract disorders,including 16 cases(1.0%)with asthma,during the Olympic Games,and 686(56.9%),including eight cases (0.7%)with asthma,during the Paralympic Games,and antibiotics were prescribed for 149(9.7%)and162(13.4%)of them,respectively.Twelve(0.8%)patients were hospitalized during the Olympic Games and four(0.3%)during the Paralyrnpie Games,and age equal to or nlore than 55 years and digestive disease were independent risk factors for hospitalization,with odds ratios(ORs) of 5.3 and 9.5 and their 95% confidence intervals(Cls)of 1.4-19.6 and 2.5-36.4,respectively.Conclusions Acute respiratory disorder was the most connnon cause for medical visits in the Polyclinic.Asthma did not play a significant role to iniluence athletes'performance in the Beijing 2008 Olympic and Paralympic Games.Antibiotic prescription in the Polyclinic had been controled to an acceptable level.Conditions in elder patients and those with digestive disorder tended to be severe.deserving more attention infuture's mass gathering.

Objective To evaluate prescribing antibiotics in medical patients visiting the polyclinic at 2008 Beijing Olympic Village for its further reasonable use. Methods Clinical prescriptions for all the medical patients at the polyclinic were reviewed retrospectively. Consistency between antibiotics prescriptions and their indications formulated before 2008 Beijing Olympic Games was evaluated, as well as related factors for their overuse. Results In total, 1537 patients visited the polyclinic and 1233 recipes were prescribed,with 956 patients (62. 2% ) with infections, including 809 (52. 6% ) of respiratory infections. One hundred and forty-nine of 1537 patients (9. 7% ) were treated with antibiotics, accounting for 12. 1 percent of all prescriptions, and 43 cases (28.9%) were identified as antibiotics overuse, including 39 cases with respiratory infections. Prevalence of antibiotics overuse was significantly more for patients of domestic employees than that for non-employees (34. 6% vs. 14.3% , P <0. 01 ), with art independent association between them (OR 3.07, 95% CI 1.11 - 8. 50). Conclusions Although the polyclinic has successfully reduced unnecessary antibiotics use, their overuse remains to be reduced, and physicians' strict adhesion to indications for antibiotics use and patient education are essential for their rational use in primary care of China.

A 68?year?old female patient was admitted to the hospital for multiple masses in the mouth and lungs as well as on dorsal hands for more than 20 days without obvious subjective symptoms. No abnormalities were found by physical examination. Dermatological examination showed two bean?sized dark?red nodules on the upper jaw as well as one pigeon egg?sized dark?red nodule on the left dorsal hand, and all the nodules were hard with smooth surfaces and limited mobility. Positron emission tomography?computed tomography (PetCT) revealed multiple metastases to the brain, lymph nodes, lungs, gastrointestinal tract, both kidneys, multiple bones and intermuscular tissues. Pathology of nodules from the upper jaw showed lowly differentiated tumor cells with osteoid matrix, chondroid structures and tumor bone in local areas, and immunohistochemical examination of tumor cells found positive staining for S100(focally), vimentin, CD99, P63 and Ki?67(60%), but negative staining for keratin. A diagnosis of osteosarcoma of the right side of the upper jaw was considered. Pathology of nodules from the dorsal hand revealed no obvious abnormalities in the epidermis, while there was a diffuse infiltration of medium?to large?sized histiocyte?like cells in the whole dermis with cell atypia and irregularly red?stained bone matrix and tumor bone in some regions. Immunopathology showed positive staining for Ki67(60%), and negative staining for CD3, CD10, CD20, Bcl?2, and Bcl?6. A diagnosis of cutaneous metastasis of osteosarcoma was made. The patient refused further treatment and died 6 months after the onset of lesions.

OBJECTIVETo explore the clinical outcomes of multi-ligaments reconstruction with single tendon in treating acute joint dislocation of the first carpometacarpal.

METHODSFrom December 2008 to October 2012, 4 patients with acute dislocation of the first carpometacarpal were treated with single carpi radialis longus tendon to reconstruct periarticular four ligaments, which included dorsal ligament, palmar ligament, dorsal radiocarpal ligament, and intermetacarpal ligament between the first and second. There were 3 males and 1 female aged from 22 to 63 years old with an average of 38.7. X-ray, JAMAR grid strength testing, range of motion of carpometacarpal joint and VAS score were used to evaluate clinical outcomes.

RESULTSAll patients were followed up from 6 to 40 months with an average of 19 months. The wound were healed well at stage I. No dislocation of the first carpometacarpal joint and signs of joints degeneration occurred on X-ray at 1, 3 and 6 months after operation. JAMAR grip strength recovered from 60 percent to 90 percent of health wide. The results of ROM showed 3 cases recovered flexion and extension of joints and 1 case limited adduction. VAS score was 0 to 1.

CONCLUSIONFor acute dislocation of the first carpometacarpal joint, reconstruction four ligaments with single carpi radialis longus tendon can be considered the selected treatment,which can restores joint stability and improve joint function.

OBJECTIVETo compare anatomical differences between subinguinal and ilioinguinal approaches for the treatment of acetabular fracture and investigate clinical therapeutic effect of subinguinal approach.

METHODSSeven fresh human bodies were chosen, comparative study were performed on the right and left side on the same specimen. Ilioinguinal approaches were adopted on the left and subinguinal were adopted on the right. Inner part of incision started to sun wild above pubic symphysis at 2 cm, and lateral incision ranged from iliac to anterior superior spine about 5 cm. Length and transverse diameter of the first window exposed and lliopsoas freeness were tested and compared. Fifteen acetabular fracture patients treated through subinguinal approach were compared from May 2010 to August 2012. Among all patients, including 12 males and 3 females aged from 20 to 65 years old with an average of 40.6 years old. Matta criteria were used to evaluate clinical outcomes.

RESULTSLength and transverse diameter of the first window exposed and lliopsoas freeness through subinguinal approach were better than through ilioinguinal approach (P<0.01). In 15 patients with acetabular fracture, 10 patients obtained anatomical reduction and 10 patients got satisfied reduction in accordance with Matta criteria. X-ray results of all patients were excellent.

CONCLUSIONCompared with ilioinguinal approach, subinguinal approach could enlarge visualization of the first window and simplify surgical procedure. It is an ideal approach to expose anterior and anterior-medialis wall of acetabulum and anterior hip capsule.
