Article Abstract

Primary and revision total hip arthroplasty can be complicated by intrapelvic migration of the acetabular components. This complication constitutes an evolutionary turning point in the history of this prosthesis since it could lead to compression or invasion of noble intra-pelvic structures. The second problem lies in the extraction of these implants in this anatomically dangerous region. We report the case of a patient who was operated on for a septic loosening of her total hip arthroplasty with protrusion of the acetabular components (Kerboull cross-plate and the cup) intrapelvicly via the para-rectus approach which allowed safe removal of these implants. This is an intra-pelvis approach lateral to the rectus abdominis muscle, initially described in acetabular fractures, with few studies reporting its use in this type of complex situations.

Background: Postoperative pain following total hip arthroplasty (THA) may occur in a few patients but may pose a significant challenge to surgeons if the etiology is not identified. Herein, we report the case of a patient who developed late-onset pain following THA due to screw penetration of the iliopsoas tendon.

Case Summary: We report the case of a 77-year-old man who developed inguinal pain 7 years after THA.

Objective: To review the research progress of different surgical approaches in the treatment of acetabular both-column fractures.

Methods: The domestic and foreign related research literature on surgical approaches for acetabular both-column fractures was extensively consulted. The anatomical characteristics, exposure ranges, advantages, disadvantages, and indications of various common surgical approaches for both-column fractures were mainly summarized.

Background: The aim of this paper was to evaluate the safety and feasibility of robotic-assisted laparoscopic partial nephrectomy (RAPN) performed using the da Vinci Single-Port (SP) platform.

Methods: A retrospective review was conducted from December 2018 to December 2019 of 14 consecutive patients with localized renal cancer who underwent SP robot-assisted partial nephrectomy at a single institution. The procedures were performed by 2 experienced robotic surgeons, reproducing the steps of the standard multiport robotic approach to partial nephrectomy.

Objective: The aim of this study is to evaluate the efficacy and feasibility of three-dimensional printing (3D printing) assisted internal fixation of unstable pelvic fracture from minimal invasive para-rectus abdominis approach.

Methods: A total of 38 patients with unstable pelvic fractures were analyzed retrospectively from August 2012 to February 2014. All cases were treated operatively with internal fixation assisted by three-dimensional printing from minimal invasive para-rectus abdominis approach.
