Analysis of related factors of scheduled ICU before primary hip arthroplasty.

Background: Methods for improving the safety of medical treatments for patients, reducing the occurrence of postoperative complications and optimizing medical resources for primary hip replacement are needed. Previous literature has mostly analysed the risk factors and constructed and models to predict a transfer to the ICU after surgery, and no reports on preoperative ICU reservations have been found. This study evaluated the risk factors for preoperative ICU reservation and considered the necessity of preoperative ICU reservations to optimize preoperative communication, enable a seamless transfer between the operating room and ICU, reduce postoperative complications and shorten hospital stays.

[Effect of indwelling drainage tube and extubation time on recessive hemorrhage and functional recovery after total hip arthroplasty].

Objective: To study and compare the effect of indwelling drainage tube and extubation time on occult hemorrhage and functional recovery after total hip arthroplasty(THA).

Methods: From July 2017 to June 2018, 123 patients who underwent THA in our hospital for the first time were selected as the subjects of study. According to whether the drainage tube was retained or not and the time of extubation, they were divided into three groups:in group A, 41 patients (24 males, 17 females, age 53 to 77 years) did not put drainage tube after THA;in group B, 41 patients were removed 24 hours after THA, 26 males and 15 females, aged 55 to 74 years;in group C, 41 patients were removed 48 hours after THA, 25 males and 16 females, aged 52 to 75 years.

[Treatment of Pipkin type I and II femoral head fractures through modified Smith-Peterson approach and modified Hardinge approach-a case-control studies].

Objective: To compare clinical results of treatment of Pipkin type I and II femoral head fractures through modified Smith-Peterson(S-P) approach and modified Hardinge approach.

Methods: From July 2005 to July 2014, 42 patients with Pipkin type I and II femoral head fractures were treated with operation. A total of 23 patients in anterior group was treated with modified S-P approach including 17 males and 6 females with an average age of (29.
