OBJECTIVES: The aim of this study was to evaluate the results on anterior decompression and fusion with titanium mesh or expanding cage and plate fixation in patients with cervical myelopathy. METHODS: We conducted a retrospective multicentric review of 114 patients, 75 males and 39 females, with cervical myelopathy who underwent surgical treatment between July 2009 to December 2011. All surgeries were performed via a ventral approach. Based on the type of surgery the patients received, they were divided into 3 groups: group 1 consisted of 49 patients who received multilevel corpectomies and fusion with strut iliac bone graft and plates; group 2 consisted of 26 patients who received multilevel corpectomies and fusion with titanium expanding cage and plating; group 3 consisted of 39 patients who received multilevel corpectomies and fusion using titanium mesh with autologous bone graft and anterior plating...

Distraction osteogenesis is an effective method for generating large amounts of bone in situ for treating pathologies such as large bone defects or skeletal malformations, for instance leg-length discrepancies. While an optimized distraction procedure might have the potential to reduce the rate of complications significantly, our knowledge of the underlying mechanobiological processes is still insufficient for systematic optimization of treatment parameters such as distraction rate or fixation stiffness. We present a novel numerical model of lateral distraction osteogenesis, based on a mechanically well-controlled in vivo experiment...

Surgical meshes are effective and frequently used to reinforce soft tissues. Fibrin glue (FG) has been widely used for mesh fixation and is also considered an optimal vehicle for stem cell delivery. The aim of this preclinical study was to evaluate the therapeutic effect of MSCs and their exosomes combined with FG for the treatment of incisional hernia. A murine incisional hernia model was used to implant surgical meshes and different treatments with FG, MSCs and exo-MSCs were applied. The implanted meshes were evaluated at day 7 by anatomopathology, cellular analysis of infiltrating leukocytes and gene expression analysis of TH1/TH2 cytokines, MMPs, TIMPs and collagens...

INTRODUCTION: Postoperative chronic pain is an important outcome of hernia surgery. In laparoscopic hernia surgery, either fixation outside the trapezoid of disaster or no fixation is recommended to avoid postoperative pain. To avoid recurrence are transabdominal preperitoneal (TAPP) hernia repair, the myopectineal orifice must be covered with mesh during TAPP, but lifting or shrinking of the mesh can lead to recurrence. The aim of this study was to evaluate the feasibility of a novel technique for mesh fixation to prevent the mesh from lifting off...

BACKGROUND: Primary repair of large hiatal hernia is associated with a high recurrence rate. The use of mesh can lead to a reduce of recurrence rate. Despite this reduction, the type of mesh used and the placement technique are controversial. In our study, we used a new type of non-absorbable, self-fixating mesh to reinforce the cruroplasty. The aim of the present study was to compare the long-term results of laparoscopic treatment of large hiatal hernia with mesh reinforcement versus simple crura repair...

For this study we developed an anatomical thin titanium mesh (ATTM) plate for Asian zygomaticomaxillary complex (ZMC) fracture repair with reduction guidance and fixation function. The ATTM plate profile was designed as an L-shape to fix at the anterior maxilla and lateral buttress of the ZMC. Computer-aided stamping analysis was performed on four screw-hole patterns in the ATTM plate - a control without screw-holes, square screw-holes, double screw-holes, and large-diameter, double screw-holes - using upper/lower dies of averaged ZMC reconstruction models...

STUDY DESIGN: A case report. OBJECTIVE: To outline the potential risks of late bleeding from the segmental vessels following less invasively dorsolateral approaches to the thoracolumbar spine. SUMMARY OF BACKGROUND DATA: A low risk of major intraoperative bleeding, associated traditional dorsolateral approach to the lumbar spine is reported , but segmental arteries and great vessels may be rarely damaged. Spine surgeons who are involved with these approaches should be aware of these rare but potential dangerous vascular complication because they could be life threatening, particularly in elderly patients with increased morbidity, and/or metastatic disease to the spine...

Midurethral mesh sling is the most performed incontinence procedure. This hypotheses propose knotless barbed suture could be positioned as a tension-free trans-vaginal sling under the mid-urethra without vaginal incision. Knotless suture sling support and stabilize mid-urethra when intraabdominal pressure increase. This procedure is designed to replace midurethral mesh sling operation, aiming at reducing complications. It is completed in a similar way with retropubic mesh sling procedure, and less invasive...

Treatment of patella fractures is fraught with complications and historically poor functional outcomes. A fixation method that allows for early mobilization and decreases symptomatic hardware rates will improve knee range of motion, postoperative functional status, and reoperation rates. The purpose of this study was to evaluate the functional outcomes after locked plate osteosynthesis of patella fractures at a Level 1 trauma center. A retrospective case series was conducted of patients who underwent open reduction internal fixation (ORIF) of a patella fracture using a locked mesh plating technique coupled with neutralization of forces on the distal pole of the patella...
