The ACL was completely ruptured from the proximal footprint and the tibial side residual remained intact. There were 19 males and 5 females; 16 cases on the right side and 8 cases on the left side. The mean age was 27.88±7.13 years old; The interval between injury and surgery was 14.83±9.09 d; The dissociate peroneus longus tendon and semitendinosus tendonfrom the injured extremity were folded in half, then braided and trimmed into ACL graft for use. The ACL remnant was preserved and the graft was pulled through the stump for single bundle anatomic intrathecal reconstruction. The ACL graft was fixed with Endobutton on the femoral side and interference screw on the tibial side. The results of Lachman test, Lysholm scores, Tegner scores and International Knee Documentation Committee (IKDC) subjective scores of knee before operation and at final visit were recorded to evaluate the stability and function of the knee. Visual analogue score (VAS) was used to record the changes of pain at the site where the peroneal longus tendon was harvested. The American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scores were recorded before injury and at the final visit to assess the effect of ankle function after peroneal longus tendon resection. \u0000 \u0000 \u0000Results \u0000The diameter of the ACL graft made of dissociate peroneus longus tendon and semitendinosus tendon is 8.88±0.30 mm. All patients were followed up at the outpatient clinic, with an average of 34.38±5.40 months, and no serious complications such as rerupture and joint infection were found. There were 16 grade B, 6 grade C and 2 grade D for preoperative Lachman test, none with hard end point. At last vist, there were 23 cases of grade A and 1 grade B, all with hard end points for Lachman test. At the preoperative and final visit, the Lysholm scores of the knee joint were 35.20±11.92 and 94.29±2.92 (t=23.850, P=0.000). Tegner scores were 3.46±0.93 and 8.04±1.00 (t=16.653, P=0.000). The subjective IKDC scores of knee joint were 47.63±13.06 and 91.71±3.75 (t=15.972, P=0.000). At the final visit, all the indicators of the knee were improved compared with those before surgery, and the difference was statistically significant.The AOFAS scores before injury and at the final visit were 98.83 (2.78) and 98.17 (4.01), respectively, with no statistically significant difference (t=1.850, P=0.076) .

Since the idea of \"safe zone\" being proposed, such idea has long been obeyed by hip surgeons but has also been challenged in recent years. This is because post-operative instability could happen even if acetabular components are placed within \"safe zone\" . The latest researches have demonstrated that sagittal spinal balance and spino-pelvic mobility can affect the spatial orientation of acetabular components. Factors including spinal degenerative changes, long lumbosacral changes and spinal ankyloses can lead to sagittal spinal imbalance and/or influence spino-pelvic mobility, which subsequently affect pelvic retroversion. Proper pelvic retroversion is a way to compensate for sagittal spinal imbalance and is beneficial to post-operative stability. It is necessary for hip surgeons to rethink \"safe zone\" before performing THA and understand spinal balance as well as spinopelvic mobility. The goal is to reduce the rate of dislocation. This review started by introducing the related spinopelvic parameters frequently seen in papers published recently and the definitions of acetabular cup orientations. After the spinal sagittal balance and its compensatory mechanisms session, discussed its clinical relevance, as well as the significance of spinal mobility, in spinopelvic motion under three different postures.","PeriodicalId":36405,"journal":{"name":"中华骨科杂志","volume":"40 1","pages":"103-109"},"PeriodicalIF":0.0,"publicationDate":"2020-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48606434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All patients received implantation of porous tantalum rod. The 3D C-arm X-ray positioning was used in 24 patients (29 hips), while traditional C-arm X-ray positioning was performed in the other patients. The visual analogue scale (VAS), Harris score and superior rate were evaluated at 0.5, 1, 2, and 4 years after the surgery. Total hip arthroplasty was regarded as the end event for survival rate. \u0000 \u0000 \u0000Results \u0000In the 3D C-arm X-ray positioning group, the VAS score decreased from 7.17±1.00 points preoperatively to 2.38±0.86 points at half year, to 2.10±1.40 points at 1 year, to 2.38±1.66 points at 2 years, and to 2.21±1.47 points at 4 years postoperatively (F=98.78, P=0.00). Meanwhile, the Harris score increased significantly from 73.97±3.49 points preoperatively to 89.90±1.93, 89.93±3.26, 89.21±5.83, 88.57±5.70 points at the follow up, respectively (F=84.35, P=0.00). According to the analysis of the pre-operative and post-operative image data, there was no significant difference in progress in the ARCO staging at 23 hips duration the follow-up. Four hips were developed to ARCO III and two hips to ARCO II. Thus, the success rate of operation was 79% (23/29). There were two hips underwent total hip arthroplasty, so the survival rate of femoral head was 93% (27/29). The trend of VAS score and Harris score in the C-arm X-ray positioning group was in accordance with the 3D C-arm X-ray positioning group but without statistically significant difference (P>0.05). The operation duration 31.38±3.96 min, blood loss 36.72±5.59 ml, the ratio of distance of metal rod to bone cortex in femoral neck 0.48±0.10, and the distance of mental rod to center of necrosis 0.18±0.07 cm in 3D C-arm X-ray positioning group was superior to C-arm X-ray positioning group (respectively 41.97±4.64 min, 41.49±4.46 ml, 0.46±0.06, 0.23±0.10 cm, P<0.05). \u0000 \u0000 \u0000Conclusion \u0000The implantation of tantalum rod in treating ARCO I-II non-traumatic femoral head necrosis can increase the function of hip joint, relieve the symptoms of necrosis of femoral head, alleviate the progress of femoral head necrosis in X-ray, and obtain a higher survival rate. The 3D C-arm positioning in surgical operation could improve the accuracy and safety of surgery. \u0000 \u0000 \u0000Key words: \u0000Femur head necrosis; Tantalum; Imaging, three-dimensional; X-rays; Radiography","PeriodicalId":36405,"journal":{"name":"中华骨科杂志","volume":"39 1","pages":"1440-1446"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42757632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
