Since therapeutic means are sparse, early awareness of potential health problems is the most important to timely start adequate prevention. The presented improved approach of acoustic joint assessment (ACOJA) is based on subsequently measured acoustic signals emitted by joints at two different mechanical load conditions with the same measurement setup, and analysing the related relative spectral signal changes. While this approach applies to almost any joint, this paper concentrates on demonstrating the capability of this approach at hip joints. It could be demonstrated that the ACOJA method is sensible enough to allow even quantification of age-related degradations at hip normal biological human joints. It allows even identifying and accounting for gender-related differences in hip joint status. This allows concluding that ACOJA will contribute to enlarge the medical possibilities of non-invasive joint diagnostics.展开更多

Methods: 120 patients with shoulder injury who were treated in our hospital (January 2020 to December 2021) and underwent surgical treatment were diagnosed as shoulder injury. They were divided into CT group, MRI group and joint diagnosis group. The detection rates of the two methods were compared. Results: In the diagnosis of shoulder injury, MRI group was higher than CT group, and the joint diagnosis group was higher than the other two groups. Conclusion: In the diagnosis of shoulder injury, the joint examination of multi-slice spiral CT and magnetic resonance imaging (MRI) can obtain a higher diagnostic rate and ideal effect.展开更多

Methods From April 1987 to December 2001, we performed 1 336 total knee replacements (TKR) in 926 patients and 1 745 total hip replacements (RHRs) in 1 566 patients. In this group there were 5 PE patients after operation. Two patients died (all after TKR), and 3 patients salvaged successfully (2 after TKR, 1 after THR). Results The total incidence of PE after TJR was 0. 2% (5/2 492), the incidence of PE after TKR was 0. 4% (4/926), and the incidence of PE after THR was 0.06% (1/1 556). In the patients who suffered PE, 2 died. The incidence of PE before 2000 was 0%. Conclusion Death after total joint replacement is due to pulmonary embolism ( PE), especially massive PE. The incidence of PE after TKR is higher than that after THR. Pulmonary angiography is the gold standard for the diagnosis of PE. With more understanding on PE and more popularity of joint replacement, the diagnosis of PE展开更多
