Objective To discuss the clinical effects of internal fixation with pubic nails and sacroiliac screws aided by 3D navigation for pelvic fractures of Tile type B2 or B3. Methods A total of 27 patients with pelvic fracture of Tile type B2 or B3 received operative treatment in our hospital from De-cember 2013 to December 2016. They were 15 men and 12 women, aged from 20 to 68 years ( average, 39. 2 years ) . According to the Tile classification, 12 cases were type B2. 1, 8 type B2. 2, and 7 type B3. Of them, 20 were unilateral pubic rami fractures and 7 bilateral pubic rami fractures; there were 3 dislocations of the sacroiliac joint, 17 fractures of the sacral Denis regionⅠ, and 7 fractures of the sacral Denis regionⅡ. All the 27 cases were treated by internal fixation with retrograde pubic nails and sacroiliac screws aided by 3D navi-gation. Quality of fracture reduction, functional recovery of the pelvis and postoperative complications were recorded to evaluate the clinical effects. Results Totally 26 out of the 27 patients were followed up for 6 to 18 months ( average, 11. 4 months ) , with one lost to the follow-up. According to the Matta scoring, the pelvic reduction was evaluated as excellent in 20, as good in 4 and as fair in 2 cases, yielding an excellent and good rate of 92. 3％. All the fractures united after 12 to 20 weeks ( average, 13. 8 weeks ) . According to the Majeed scoring at the final follow-ups, the pelvic function was evaluated as excellent in 20, as good in 3 and as fair in 3 cases, giving an excellent and good rate of 88. 5％. Screw loosening happened in one patient who had ambulated too early. No permanent pain, wound infection, neurovascular injury, heterotopic ossification or thrombosis occurred. Conclusion For the treatment of pelvic fractures of Tile type B2 or B3, internal fixation with pubic nails and sacroiliac screws aided by 3D navigation can lead to satisfactory short-term outcomes due to advantages of limited operative invasion, short operation time and limited intraoperative blood loss.

OBJECTIVETo evaluate the reliability and diagnosis accuracy of 5 special tests used for the diagnosis of subacromial impingement syndrome (SAIS).

METHODSA prospective blinded cohort study was taken,in which 105 patients with shoulder pain were reviewed. All the patients took 5 special syndrome tests including Neer syndrome, Hawkins-Kennedy syndrome, painful arc empty can test and external rotation resistance test, also underwent arthroscopic surgical examination. The Nikolaus's criterion was regarded as a golden standard for SAIS. Data accuracy analysis was calculated through a receiver operating characteristic (ROC) curve, sensitivity, specificity, positive likelihood ratio (+LR) and negative likelihood ratio (-LR). The binary Logistic regression analysis was used to find out the best test combination for ruling in or out SAIS. The interrater reliability was assessed by the Kappa coefficient and percent agreement.

RESULTSThe ROC analysis indicated a significant area under the curve (AUC) (AUC=0.62 to 0.73, P<0.05) for all tests except the Hawkins-Kennedy. Tests with a +LR greater or equal to 2.0 were the painful arc,empty can,external rotation resistance, Tests with a-LR less than 0.5 were Neer,painful are ,external rotation resistance. The regression analysis found the painful arc, empty can and external rotation resistance made the best combination for diagnosis SAIS,while the painful are and external rotation resistance made the best combination for ruling out SAIS. The difference of ROC analysis was significant with a cut-off of 3 positive tests out of 5 tests. All tests had moderate to good agreement (Kappa=0.42 to 0.71).

CONCLUSIONThe single test of painful arc, empty can and external rotation resistance, as well as 3 or more positive tests of the 5 tests can help confirm the diagnosis of SAIS, while the single test of Neer, painful arc and external rotation resistance are help rule out the diagnisis of SAIS. The tests of painful arc, empty can and ex ternal rotation resistance are the best combination for the diagnosis of SAIS (when 2 or more are positive), while the tests of painful arc and external rotation resistance are the best combination for ruling out SAIS (when both are negative)
