Scale effects on suspended sediment and their response to extreme precipitation in karst basins.

Extreme precipitation is a crucial trigger for soil erosion events in karst regions. However, the existence of a scale effect in suspended sediment characteristics of karst basins and which extreme precipitation variables control this effect remain unclear. To investigate this, we analyzed the scale effect on suspended sediment characteristics using monthly hydrological data from five karst basins of varying scales, consistently monitored from 2012 to 2019.

Modified screw-rod fixation for management of posterior pelvic ring fractures: a retrospective study.

Background: Pelvic fractures are often associated with life-threatening damage and mechanical instability. Surgical therapy is a prior choice. To minimize surgical invasion and risk, bilateral screws combined with curved rod were applied to stabilize posterior pelvic ring.

Comparison of the clinical effects for different positions of the weight-bearing axis after high tibial osteotomy.

Purpose: To analyze the clinical effects of different positions of the weight-bearing axis (WBA) after high tibial osteotomy (HTO).

Methods: The clinical data of 90 patients who underwent HTO in the Department of Orthopedics at our hospital from June 2018 to June 2021 were retrospectively analyzed. Patients were divided into groups A and B (n = 45 per group) according to different post-HTO WBA positions of the affected side.

Arthroscopic Subscapularis Tendon Repair Using the Mason-Allen Technique.

Background: Arthroscopic rotator cuff repair has recently been popularized for treating tears. In a biomechanical trial, the Mason-Allen stitch improved the fixation quality of poorly vascularized tendons. The use of this technique involving the subscapularis tendon remains rare.
