An Alternative Intraoperative Radiographic Method for Optimizing Cup Inclination during Total Hip Arthroplasty.
During total hip arthroplasty (THA), the location of the acetabular prosthesis is very important for guaranteeing successful surgery. However, this remains a challenge for many surgeons. This study aimed to investigate the feasibility of using the intraoperative fluoroscopic iliopubic tangential angle (IPTA) to determine the valgus angles of acetabular prostheses. ⋯ The IPTA (at the apex of the true acetabulum) and angle θ (obtained by intraoperative fluoroscopy) are consistent in determining the postoperative valgus angle of acetabular prosthesis during THA. Thus, IPTA and angle θ are of value in guiding placement of acetabular prostheses; in particular, this method can facilitate the learning of young surgeons.

Can an Endplate-conformed Cervical Cage Provide a Better Biomechanical Environment than a Typical Non-conformed Cage?: A Finite Element Model and Cadaver Study.
To evaluate the biomechanical characteristics of endplate-conformed cervical cages by finite element method (FEM) analysis and cadaver study. ⋯ Endplate-conformed cages can decrease cage-endplate interface stress in all directions of motion and increase cervical stability in FLE-EXT. Additionally, adjacent segments are possibly protected because intra-disc stress and facet loading are smaller after endplate-conformed cage implantation. However, axial stability was reduced in group C, indicating that endplate-conformed cage should not be used alone and an anterior plate system is still important in anterior cervical discectomy and fusion.

Randomized Controlled TrialClosed Suction Drainage Is Not Associated with Faster Recovery after Total Knee Arthroplasty: A Prospective Randomized Controlled Study of 80 Patients.
To evaluate whether closed suction drainage (CSD) is associated with early recovery of knee function in patients undergoing total knee arthroplasty (TKA). ⋯ In this randomized study, primary TKA without CSD was associated with faster recovery related to less local inflammation and better early knee function. Furthermore, use of a drain had no significant advantage with respect to other outcome measures and may have increased costs. Based on these data, CSD after primary TKA is not routinely indicated.

Multicenter StudyClinical and Radiographic Results of Reconstruction with Fibular Autograft for Distal Radius Giant Cell Tumor.
To evaluate the result of en bloc resection and reconstruction of the distal radius with a non-vascularized fibular autograft for giant cell tumor (GCT) of bone. ⋯ Reconstruction with a non-vascularized proximal fibular autograft is a reasonable option after en bloc resection of the distal radius for giant cell tumor of bone.

En Bloc Resection of Primary Malignant Bone Tumor in the Cervical Spine Based on 3-Dimensional Printing Technology.
To investigate the feasibility and safety of en bloc resection of cervical primary malignant bone tumors by a combined anterior and posterior approach based on a three-dimensional (3-D) printing model. ⋯ Though technically challenging, it is feasible and safe to perform en bloc resection of cervical primary bone tumors. This is the most effective means of managing cervical spine tumors. Preoperative 3-D printing modelling enables better anatomical understanding of the relationship between the tumor and cervical spine and can assist in planning the surgical procedure.
