BACKGROUND:Finite element analysis has been widely used for the research of bone and joint biomechanics, but the reports about finite element analysis of distal tibial articular surface defect are rare at home and abroad. OBJECTIVE:To establish ankle three-dimensional finite element model, produce distal tibial articular surface defects with different areas, and to simulate the distal tibial articular surface deformation and displacement under the different phases, thus predict the maximum al owable degree of distal tibial articular surface defect and explore the mechanics pathogenesis of ankle traumatic arthritis. METHODS:Continuous tomographic images were obtained by multi-slice spiral CT scan of a normal adult male ankle, and then the images were imported into the Mimics medicine modeling software to generate a entity model;the large general-purpose finite element analysis software ANSYS 13.0 was used for meshing, material property assignment and generating a finite element model. Restricted boundary conditions and simulated ankle distal end axial force, and then the stress distribution and displacement results of distal tibial articular surface in different phases were obtained. RESULTS AND CONCLUSION:The total number of units of the established finite element model of ankle joint was 157 990, and the total number of nodes was 193 801. On three phases, with the increase of the distal tibial defect area, the contact area was gradual y decreased, especial y in plantar flexion with the defect diameter of 13 mm, the change of the area was most obvious;The contact area of the neutral position was largest;with the increase of the distal tibial defect area in the neutral position and dorsiflexion, the peak stress was increased gradual y, and significantly increased after the diameter changed into 11-13 mm;in the neutral position and 10° of dorsiflexion, the peak stress mainly concentrated in the posteromedial and posterolateral quadrant;in 10° of plantar flexion, the change was complex, and when the diameter was 11-13 mm, the peak stress was increased gradual y with the increasing of defect area, when the diameter increased to 13 mm, the peak stress reached maximum. The maximum diameter of distal tibial articular surface defect was considered to be 11-13 mm. The joint function wil be affected when the diameter of distal tibial articular cartilage and bone bed defects was more than 11-13 mm.

OBJECTIVETo investigate the effect and safety of extracorporeal shock wave (ESW) in the treatment of pain symptom of type III B prostatitis.
METHODSWe treated 50 cases of type III B prostatitis by ESW once a week for 4 weeks. Then we evaluated the clinical effect and safety of the therapy based on the NIH-CPSI scores, visual analogue scale (VAS) scores, IIEF-5 scores, prostate volume and morphous, state of urination, color of urine, results of routine semen analysis, and changes of cytokines (IL-6, TNF-α and IL-1β) in expressed prostatic secretion (EPS).
RESULTSAll the patients successfully accomplished the treatment. Compared with the baseline, decreases were observed after 4 weeks of cytokine treatment in the pain scores (14. 61 ± 1. 82 vs 9. 36 ± 1. 47, P <0. 01), urination symptom scores (4. 59 ± 1. 01 vs.4. 66 ± 0. 89, P >0. 05) , quality of life scores (6. 51 ± 1. 03 vs 4. 56 ± 1. 02, P <0. 01), NIH-CPSI (25. 43 ± 1. 72 vs 18. 28 ± 2. 32, P <0. 01 ), and VAS (6. 59 ± 1. 10 vs 3. 02 ± 1. 07, P < 0. 01). The concentration of IL-6 in the EPS was significantly increased ([55.82 ± 6. 28] vs [86.59 ± 4. 55] ng/ml, P <0. 01) , while the level of TNF-α ([3.89 ± 0. 12] vs [3. 19 ± 0.22] ng/ml, P<0.01) and that of IL-1β ([3.21 ± 1.01] vs [1.48 ± 0.95] ng/ml, P< 0. 01) remarkably reduced after treatment. However, there were no statistically significant differences in IIEF-5 scores (18. 58 ± 2. 03 vs 18. 51 1. 89, P >0. 05) or various sperm parameters before and after treatment (P >0. 05). And no significant changes were observed in the prostate volume, morphous or internal echoes.
CONCLUSIONThe ESW therapy is effective and safe for the pain symptom of type III B prostatitis.
