Silver Negative Pressure Dressing With Vacuum-assisted Closure of Massive Pelvic and Extremity Wounds.

Clin Orthop Relat Res. 2013 Jun 29;

Authors: Siegel HJ, Herrera DF, Gay J

Abstract
BACKGROUND: Massive soft tissue loss involving the pelvis and extremities from trauma, infections, and tumors remains a challenging and debilitating problem. Although vacuum-assisted closure (VAC) technology is effective in the management of soft tissue loss, the adjunct of a silver dressing in the setting of massive wounds has not been as well tested.
QUESTIONS/PURPOSES: Does a silver negative pressure dressing used in conjunction with a wound VAC decrease (1) the length of acute hospital stay and overall length of treatment; (2) the number of surgical débridements the patients underwent as part of their care; and (3) the likelihood of wound closure without soft tissue transposition?

Local Alendronic Acid Elution Increases Net Periimplant Bone Formation: A Micro-CT Analysis.

Clin Orthop Relat Res. 2013 Jun 29;

Authors: Bobyn JD, Thompson R, Lim L, Pura JA, Bobyn K, Tanzer M

Abstract
BACKGROUND: Fixation of cementless orthopaedic implants is not always achieved, particularly in challenging scenarios such as revision surgery, trauma, and tumor reconstruction. An adjunct therapy for improving implant fixation would improve the reliability and durability of certain reconstructive procedures.
QUESTIONS/PURPOSES: The purpose of this study was to determine the effect of local elution of the bisphosphonate alendronic acid on bone formation around porous titanium implants in an animal model.
METHODS: Porous-coated cylindrical rods were coated with either 0.2 mg or 1.0 mg alendronic acid before bilateral surgical implantation into the femoral intramedullary canals of 10 experimental dogs. Twelve weeks after surgery, the femora were harvested and scanned with micro-CT to quantify the percentage volume of bone within the immediate periimplant space. Four femora from two dogs were also processed for undecalcified thin-section histology and analysis with backscattered scanning electron microscopy. Three histologic sections from each of these four femora were anatomically matched with transverse micro-CT sections to enable direct comparison of the area fraction of bone within the periimplant space.

Risk Factors for Significant Wound Complications Following Wide Resection of Extremity Soft Tissue Sarcomas.

Clin Orthop Relat Res. 2013 Jun 28;

Authors: Schwartz A, Rebecca A, Smith A, Casey W, Ashman J, Gunderson L, Curtis K, Chang YH, Beauchamp C

Abstract
BACKGROUND: Wound complications following resection of a localized soft tissue sarcoma have been associated with lower extremity location, large tumor volume, and use of preoperative radiation. Some of these wounds, however, show the potential for healing with local wound care and nonsurgical techniques. We are unaware of any published data establishing factors associated with nonhealing wounds that ultimately are treated with local or free vascularized tissue transfer.
QUESTIONS/PURPOSES: The purpose of this study was to determine the variables associated with development of a significant wound complication defined as one that underwent a secondary procedure using local or free tissue transfer after resection of a localized soft tissue sarcoma.

The Araz medial linkage orthosis--a new orthosis for walking in patients with spinal cord injury: A single patient study.

Prosthet Orthot Int. 2013 Jun 24;

Authors: Arazpour M, Bani MA, Hutchins SW, Sayyadfar M

Abstract
Background:This article describes the development and evaluation of a new medial linkage orthosis to potentially assist paraplegic patients to ambulate.Case description and methods:The orthosis was initially designed using the solid works program and was subsequently evaluated when used by a spinal cord injury subject to test the structure during standing and walking. Gait analysis was used to compare the medial linkage orthosis to a standard hip-knee-ankle-foot orthosis.Findings and outcomes:The results demonstrated improvements in gait velocity, step length, and decreased compensatory motions in the new orthosis compared to the hip-knee-ankle-foot orthosis.Conclusions:The results propose that this new Araz medial linkage orthosis could be used to assist paraplegic subjects who have adequate ranges of motion and also with weakness or reduced tone to stand and walk.Clinical relevanceThe Araz medial linkage orthosis can potentially provide standing and walking assistance for spinal cord injury patients.
