Robot-assisted Percutaneous Cannulated Screw Fixation of Femoral Neck Fractures: Preliminary Clinical Results.

Objective: To assess the clinical efficacy of TiRobot-assisted percutaneous cannulated screw fixation in the treatment of femoral neck fractures.

Methods: From September 2015 to July 2017, 26 patients with unilateral femoral neck fractures were treated with TiRobot-assisted percutaneous cannulated screw fixation. The femoral necks were fixed using three cannulated screws with robot assistance applying the following procedure: image acquisition, path planning, and needle and screw placement.

Robot-assisted Minimally-invasive Internal Fixation of Pelvic Ring Injuries: A Single-center Experience.

Objective: To investigate the indications, surgical strategy and techniques, safety, and efficacy of robot-assisted minimally-invasive internal fixation of pelvic ring injuries.

Methods: The clinical data of 86 patients with anterior and posterior pelvic ring injuries who underwent robot-assisted minimally-invasive internal fixation were retrospectively analyzed. The patients included 57 men and 29 women aged between 22 and 75 years, with an average age of (40.

Robot-assisted percutaneous screw placement combined with pelvic internal fixator for minimally invasive treatment of unstable pelvic ring fractures.

Purpose: The purpose of this study was to investigate the safety and efficacy of the combination of robot-assisted percutaneous screw placement and pelvic internal fixator (INFIX) for minimally invasive treatment of unstable anterior and posterior pelvic ring injuries.

Methods: From September 2016 to June 2017, twenty-four patients with unstable anterior and posterior pelvic ring injuries were treated with TiRobot-assisted percutaneous sacroiliac cannulated screw fixation on the posterior pelvic ring combined with robot-assisted pedicle screw placement in the anterior inferior iliac spine along with INFIX on the anterior pelvic ring. The results of the treatment, including surgery duration, fluoroscopy frequency, total drilling, amount of blood loss, fracture healing time, and postoperative functional outcomes were recorded and compared with another 21 similar patients who underwent conventional manual positioning surgery.

Prosthetic Mesh Repair in the Emergency Management of Acutely Strangulated Groin Hernias with Grade I Bowel Necrosis: A Rational Choice.

The aim of this study was to determine the feasibility of prosthetic mesh repair according to the degree of bowel necrosis in the emergency management of acutely strangulated groin hernias. Emergency prosthetic mesh repair versus primary suture repair was randomly performed in 208 consecutive strangulated groin hernia patients with bowel necrosis between January 2005 and August 2016. The degree of bowel necrosis of each patient was determined according to a modified three-grade classification system.

A novel bowel necrosis classification system and examination of patient outcomes in incarcerated groin hernia patients.

The objective of this study was to determine a classification system for BN in incarcerated groin hernia patients and to explore the possible relationship between BN staging and patient outcomes. Incarcerated groin hernia patients treated with emergency bowel resection from January 2008 to December 2013 were screened for inclusion in a prospective study. A novel three-stage classification system was proposed for BN (BN stages I-III) and correlations between adverse events (AEs) and mortality with BN stage were determined.

Classifications of clinical and bowel morphological changes and their relationship with characteristics of patients with incarcerated groin hernias.

Background: There is currently no grading standard for the degree of clinical and bowel morphological changes. The objective of this study was to define clinical and bowel morphological classifications and investigate the possible relationship with the characteristics of patients with incarcerated groin hernias.

Material And Methods: We retrospectively studied 195 patients who underwent emergency hernia repair with simultaneous bowel resection between January 1992 and January 2012.

Trephine arthrodesis of subtalar joints: operative technique and clinical effect.

Objective: To review the operative technique of trephine arthrodesis of subtalar joints and evaluate its clinical effect.

Methods: From June 1998 to October 2006, we performed subtalar arthrodesis on 38 feet of 34 patients for a variety of painful disorders of hindfoot with trephine technique. Clinical and radiologic follow-up evaluations were performed for 45 months on average (range, 21 to 110 months) after arthrodesis.
