ABSTRACT
Objective:To measure the space of motion of index finger with and without injury, to apply it in rehabilitation. Methods:Thirty healthy undergraduate volunteers (controls) and three undergraduate volunteers with recent index finger injury (patients) were asked to flex, extend, adduct, abduct and ring the index finger independently and combined with middle finger, twice for a motion with an interval of 30 seconds. The index finger movement trajectory was recorded with a high-definition camera, and analyzed the range of flexion, extension, adduction, abduction and ring rotation motion with MATLAB. The movement space and defect of the injured fingers were drawn. Results:The ranges of independent flexion-extension and adduction-abduction reduced 26.5% and 24.6% in the patients compared with those of the controls, respectively. The defects of ring rotation space were very different with the degrees of recovery, and the maximum loss happened on 160°, 70° and 170°. Conclusion:Loss in index fingers motion space in range and direction may help for rehabilitation assessment.
ABSTRACT
OBJECTIVE@#To investigate the clinical effect of proximal femoral nail anti rotation (PFNA) and titanium plate in the treatment of Evans Jensen type V intertrochanteric fractures.@*METHODS@#From October 2013 to March 2016, 30 patients with Evans Jensen type V intertrochanteric fractures were analyzed. According to the operation methods, they were divided into two groups:16 cases of closed reduction and PFNA internal fixation;14 cases of small incision incision reconstruction of titanium plate reconstruction of femoral moment and lateral wall PFNA internal fixation. The operation (blood loss, operation duration), postoperative rehabilitation (postoperative ambulation time, bone healing time), operation related complications (internal fixation fracture, withdrawal, spiral blade cutting out) were observed and compared between the two groups. Harris score of hip joint function was performed 12 months after operation, and the loss degree of cervical trunk angle was observed and compared.@*RESULTS@#All the 30 patients were followed up for 12 to 18 months. The blood loss and operation duration of open reduction group were significantly greater than those of closed reduction group (@*CONCLUSION@#Evans Jensen was treated with PFNA intramedullary fixation through reduction and fixation of femoral moment and lateral wall with reconstruction titanium plate Vtype intertrochanteric fracture can restore the support of femoral moment and lateral wall to femoral head and neck, improve the stability of fracture end and internal fixation after operation, and reduce the risk of fracture end displacement, internal fixation loosening, cutting out and even fracture after treatment with PFNA alone. To shorten the bed time of elderly patients and reduce the operation related complications, it provides a new idea and method for the treatment of Evans Jensen type V intertrochanteric fracture.

<p><b>OBJECTIVE</b>To investigate the operative effect of PFNA combined with reconstructive locking plate on the treatment of comminuted femoral intertrochanteric fracture which involving the lateral wall.</p><p><b>METHODS</b>A total of 35 patients with comminuted femoral intertrochanteric fractures involving the lateral wall were surgically treated from November 2014 to January 2016. According to whether there was reconstruction of the lateral wall or not and the internal fixation method, the patients were divided into PFNA group (no reconstruction of the lateral wall), PFNA recontruction group (reconstructive locking plate was used to reconstruct the lateral wall, PFNA internal fixation). The clinical curative effect was evaluated by the analysis of operation time, intraoperative blood loss, postoperative activity time, the time of fracture healing, complications, and hip joint Harris score at 12 months after operation.</p><p><b>RESULTS</b>All 35 patients completed the operation successfully. All the incisions were healed by first intention and no incision infection or fat liquefaction occurred. All 35 patients were followed up from 12 to 16 months with an average of 14.4 months. All patients had bone healing. There was no statistical significant in surgery time and intraoperative blood loss between two groups(>0.05). There were 5 postoperative complications in the PFNA group and 1 in the PFNA combined with reconstructive locking plate group. There was a statistical difference between two groups(<0.05). The postoperative activity time, bone healing time, complications, and Harris score of PFNA reconstruction group were all superior to PFNA group, there were statistically significant differences between two groups.</p><p><b>CONCLUSIONS</b>Although the operation time and blood loss of PFNA combined with reconstructive locking plate in treatment of comminuted femoral intertrochanteric fracture which involving the lateral wall are more than those in the PFNA group, and the surgical trauma is larger than PFNA, the fracture healing time, postoperative activity time, and hip joint function were all superior to those of the PFNA group, which can effectively shorten the postoperative bed rest time, and reduce bed complications as well as improve hip joint function.</p>
ABSTRACT
Objective To compare gemstone spectrum imaging (GSI) and auto mA technology for lower extremity arterial CTA to determine whether GSI can decrease radiation dose while increase image quality.Methods Thirty patients were equally divided into a GIS group and an auto mA group.All the patients underwent arterial CTA of both lower limbs.The auto mA group had the noise index (NI) being 15.48 and the current strength range from 20 to 400 mA,and the GSI group applied scanning protocol GSI-36 and 260 mA when used for arterial CTA.The values of CT dose index volumes (CTDIvol) and dose length product (DLP) were recorded,and the effect doses (ED) were calculated.The image quality was evaluated in the two groups,and statistical analysis was carried out.Results GSI and auto mA groups had CTDIvol values being (10.30±40.00) and (9.72±2.86) mGy,DLP values being (1 206.31 ±338.6) and (1 101.4±375.5) mGy· cm,and ED values being (18.10±5.08) and (16.52±5.63) mSv,respectively.The image quality score was (2.87±0.30) in GSI group and (2.57±0.46) in auto mA group,and there were significant difference between the scores (P＜0.05).Conclusion GSI cannot decrease X-ray radiation dose while increase image quality during lower extremity arterial CTA.
