Plantar pressure distribution can reflect the force of several key points on foot while standing and walking. A comprehensive understanding of the plantar pressure distribution makes great sense in the following aspects: the understanding of the normal foot biomechanics and function, clinical diagnosis, measurement of disease extent, postoperative efficacy evaluation, and rehabilitation research. A simple plantar pressure measurement device was designed in this study. This paper uses FlexiForce flexible sensor to pickup plantar pressure signal and USB A/D board to do data acquisition. The data are transferred into a laptop and processed by a VB-based software which can display, remember and replay the data. We chose patients with hallux valgus and normal people to measure the pressure distribution and make contrast analysis of plantar pressure with this device. It can be concluded that people with hallux valgus have higher pressure on the second metatarsophalangeal joint and the distribution move outward. The plantar pressure of patients postoperative could be greatly improved compared to the preoperative. The function of this device has been confirmed.

Melorheostosis is a rare disorder of osteopathia. The clinical characteristics of melorheostosis in children is totally different from that in adults. The radiographic features of melorheostosis include the hyperostosis in endosteal on the one side of the cavum medullare and formed streakiness. The soft tissue contracture of the limb and joint deformities are the symptoms of melorheostosis. Here, the authors reported a melorheostosis case of 6 years old girl who suffered from severe valgus deformity of the right knee with permanent patellar dislocation. A surgical stabilization was applied with lateral soft tissue release, medial soft tissue stabilization and transferred the vastus medialis laterally (kinetic stability). After 19 years follow up postoperatively, the limb developed well in satisfied alignment with good function of knee joints, even participated in some sports activities. Other authors reported a similar case of melorheostosis with surgical treatment and achieved good outcomes in limb realignment and reduction. The further suggested that the surgical treatment should be produced before epiphyseal closure.

Objective To evaluate the method and clinical effect of subtalar joint distractor assisted open reduction and internal fixation of comminuted intra-articular calcaneal fracture.Methods Twenty-two patients with fresh closed calcaneal fracture treated with open reduction and internal fixation from May 2011 to July 2013 were included in the study.According to the modes of operation,the patients were randomly divided into two groups (n =11 in each):in group A patients underwent fracture reduction assisted by subtalar joint distractor and in group B patients underwent Steinmann pin traction and poking reduction.All were fixed using the lateral calcaneal plate.Operation time,B(o)hler angle,Gissanes angle,calcaneus height,incision healing time and complications of the two groups were investigated for evaluating the effect of operation.Clinical effect was evaluated using the American Orthopedic Foot & Ankle Society (AOFAS) score before the removal of internal fixation.Results Period of follow-up was (14.3±0.8)months (range,12 to 18 months).Two patients in group B had delayed wound healing,and were treated with regular wound care.At the final follow-up,no infection,nonunion,malunion and internal fixation failure were observed.B(o)hler angle,operation time and calcaneus height observed in group A were superior to those in group B (P ＜0.01).There was no significant difference in Gissanes angle between the two groups (P ＞ 0.05).Compared to the preoperative data,B(o)hler angle,Gissanes angle and calcaneus height were significantly improved in both groups (P ＜0.01).AOFAS score was (83.6 ± 1.4) points in group A and (81.7 ± 1.5) points in group B.Conclusion Subtalar joint distractor assisted open reduction and internal fixation is effective to shorten operation time,improve fracture reduction,reduce wound complications and increase the operative effect for comminuted intraarticular calcaneal fracture.

BACKGROUND:Percutaneous vertebroplasty with bone cement plus hyperextension position reset for acute thoracolumbar vertebral osteoporotic compression fractures has been reported to achieve good clinical efficacy.OBJECTIVE:To evaluate the efficacy of unilateral percutaneous vertebroplasty with bone cement plus hyperextension position reset for Kümmell disease in the elderly.METHODS:Twenty-two old patients with Kümmell disease were included,involving 8 males and 14 females,aged 55-84 years old,and the injuried vertebrae included T11 (n=2),T12 (n=8),L1 (n=7),L2 (n=4),L3 (n=2),L4 (n=2),and L5 (n=1).All patients underwent the unilateral percutaneous vertebroplasty with bone cement plus hyperextension position reset.The visual analogue scale and the Oswestry Disability Index scores,vertebral body height as well as vertebral kyphosis angle were determined before and after treatment.RESULTS AND CONCLUSION:(1) All patients were successfully operated,pain relieved or disappeared within 24 hours postoperatively.No spinal cord injury,pulmonary embolism and other complications were found.One patient presented with cement leakage without obvious clinical symptoms;two patients had non-adjacent vertebral fractures during follow-up.(2) The visual analogue scale and Oswestry Disability Index scores at 1 day postoperatively were significantly lower than those at baseline (P ＜ 0.05).(3) The anterior,medial and posterior height of involved vertebral body,kyphotic angle of involved vertebral body at 1 day postoperatively were significantly higher than those at baseline (P ＜ 0.05).(4) These results manifest that unilateral percutaneous vertebropiasty with bone cement plus hyperextension position reset to treat Kümmell disease in the elderly can significantly relieve back pain,restore partial vertebral height,correct local kyphosis and improve functional recovery of the injured vertebrae.

Objective To work out the Cerebral Palsy-Gross Motor Function Questionnaire(CP-GMFQ) and evaluate the reliability,validity and responsiveness of CP-GMFQ.Methods 160 children with cerebral palsy(CP)(97 males and 63 females;average age: 47.7±20.1 months,range: 18～90 months) were involved.The first 27 children received second assessment to assess test-retest reliability with a interval of 7 to 18 days.Criterion-related validity was evaluated by comparing CP-GMFQ scores with Gross Motor Function Classification System(GMFCS) levels and scores of Gross Motor Function Measure(GMFM).21 children were randomly selected for responsiveness analysis by effect size.After a interval of 3 to 7 months the re-assessment GMFQ and GMFM were tested.30 children were randomly selected for comparative testing time of GMFQ and GMFM.Results GMFQ had excellent test-retest reliability(ICC=0.9940);criterion-related validity was excellent between GMFQ scores and GMFCS levels and GMFM scores(r=0.77～0.92).Effect size of GMFQ(0.34) between GMFM88 and GMFM66,testing time of GMFQ(average 4.7±1.6 min) were significantly less than testing time of GMFM(average 17.7±4.6 min)(P<0.001).Conclusion The reliability,validity and responsiveness of GMFQ are satisfying.The gross motor functions of children with cerebral palsy could be easy and reasonably measured by GMFQ.

Objective To analyze the correlation between gross motor function and activities of daily living(ADL)in children with cerebral palsy.Methods 42 children with CP(26 males,16 females,average age 49.5±21.5 months,11 children with spastic quadriplegia,22 with spastic diplegia,5 with spastic hemiplegia,2 with athetosis and 2 with dystonia)were assessed with Gross Motor Function Classification System(GMFCS)and Gross Motor Function Measure(GMFM)for the assessment and classification of gross motor function.Pediatric Evaluation of Disability Inventory(PEDI)was used to assess the ADL.The ADL of children with different levels of GMFCS and the correlation between gross motor function and ADL were analyzed.Results The more severe of GMFCS,the less standard score of PEDI.There was the highest correlation between the GMFM66 scores and scaled scores of PEDI in mobility and social function(r=0.84),whereas a weaker correlation appeared between GMFM66 scores and scaled scores of PEDI in social function(r=0.72).Conclusion Since the gross motor function of children with CP greatly affects the ADL,the gross motor function training should be the main item for CP children,the training goal of ADL should be made according to the levels of GMFCS.

Objective To explore the effect and mechanism of relaxin on the production of extracellular matrix (ECM) excreted by high glucose stimulated human renal mesangial cells.Methods Cultured human mesangial cells (HMCs) were divided into three groups:(1) normal glucose group (NG,5.5 mmol/L D-glucose),(2) high glucose group (HG,30 mmol/L D-glucose),and (3) high glucose + relaxin group.Cell count kit (CCK8) was used to examine the cell proliferation.The levels of fibronectin and collagen type Ⅳ in the culture supernatants were examined with a solid-phase enzyme-linked immunoadsorbent assay (ELISA);Western blot method was used to detect the expression of α-smooth muscle actin (α-SMA) protein.The transforming growth factor-β1 (TGF-β1) mRNA expression was detected with quantitative polymerase chain reaction (qPCR) method.Results No proliferation and inhibition effects were observed in both normal and high glucose group.Compared to the normal glucose group,the levels of fibronectin,and collagen type Ⅳ increased significantly (57.28 ± 0.59 vs 41.85 ± 0.03,56.52 ± 0.88 vs 33.80 ± 0.24,P ＜ 0.01)after cultured 48 h in high concentration of glucose.Compared to the high glucose group,a significantly decreases of fibronectin and collagen type Ⅳ (47.08 ± 0.03 vs 57.28 ± 0.59,36.16 ± 0.52 vs 56.52 ±0.88,P ＜0.01) were observed in the relaxin treated group.The expressions of α-smooth muscle actin and TGF-β1 were decreased (P ＜0.01).Conclusions Relaxin can suppress the overproduction of ECM excreted by HMC cultured in high ambient glucose,and its mechanism is partly due to the inhibition of TGF-β1.

Objective To investigate the clinical efficacy of fixation of distal radius fracture with dorsal instability with locking compression plate (LCP) via radial approach.Methods From September 2009 to October 2012, 21 cases underwent LCP fixation of the distal radius fracture with dorsal instability via radial approach.The study included 14 males and 7 females (mean age, 54.5 years;range, 38-81 years).Twelve cases were injured in traffic accidents, 7 in falls and 2 in high falls.Fracture AO classification was type A3 in 10 cases, type C1 in 8 cases and type C2 in 3 cases.Two cases (one type A3 and one type C1) had malunion.When the lateral column, intermediate column, radial edge and dorsal plane were exposed by radial incision, LCP fixation with bone grafting was performed to restore the height of radial styloid process, ulnar deviation and palmar tilt.According to the GartlandWerley score, wrist joint function was evaluated.Results Mean duration of follow-up was 13.5 months (range, 12 to 24 months).Stage Ⅰ bone union was shown on X-rays, with the healing time of 7.5 weeks.Based on the X-rays at postoperative 6 months, 1 year and 2 years, the shortening of radial styloid process was ≤ 2 mm, mean volar tilt was 12.5°(range, 8°-17°) , mean ulnar tilt was 20.5° (range, 15°-26°), and step-off or gap of the articular surface was ≤ 2 mm.In postoperative wrist motion assay, mean volar flexion was 60°(range, 30°-70°), mean dorsal flexion was 55° (range, 30°-65°), mean radial deviation was 17°(range, 10°-20°), mean ulnar deviation was 25.5° (range, 20°-30°),pronation was 65.5° (range, 60°-70°) , and mean supination was 75.5° (range, 60°-80°).Mean grip strength was 75％ (60％-95％)of the contralateral side.Two cases suffered from pain (one complained of moderate pain and one minor pain occasionally).According to the Gartland-Werley score, 16 cases were rated excellent, 2 good, 2 fair and 1 poor, with the excellent rate of 86％.No complication was found as injury of the superficial branch of radial nerve, infection, nonunion, nail loosening, medium neuritis and tendon injury.Conclusions Lateral column, intermediate column, radial edge and dorsal plane can be shown via the radial approach.LCP fixation combined with bone grafting contributes to fracture anatomical reduction.
