Tornier Announces First Implant in U.S. Trial of Its Simpliciti Stemless Shoulder Joint Replacement System

Tornier N.V. (Amsterdam, The Netherlands), an orthopedic surgical solutions company, has announced the first implant of its Simpliciti stemless shoulder joint replacement system as part of an FDA -approved, investigational device exemption (IDE) study. The Simpliciti system is designed to allow surgeons to carry out total shoulder replacements without the complications, additional bone removal and time associated with conventional stemmed implants.

Functional reconstruction of ischemic contracture in the lower limb.

Ischemic contracture in the lower limb is a devastating complication after lower limb trauma. The prevention of contracture is much more important than the treatment of an established contracture. Split Achilles tendon transfer to flexor hallucis longus tendon and sural-tibial nerve anastomosis, which was initially implemented by us, could improve the functional recovery of ischemic contracture in lower limbs, and thus provides a new alternative for functional reconstruction of ischemic contracture in the lower limb.

Management of Grade III Open Dislocated Ankle Fractures: Combined Internal Fixation with Bioabsorbable Screws/Rods and External Fixation.

Isolated dislocation of the ankle with grade III open fracture has been scarcely reported. These ankle injuries usually involved mortise fractures, complete dislocation of the tibial astragaloid joint, capsuloligamentous structure disruption, and severe soft-tissue damage. There is no well-recognized regimen that would result in desirable outcomes. Ye T, Chen A, Yuan W, Gou S. J Am Podiatr Med ssoc. 2011 Jul-Aug;101(4):307-15. PMID: 21816999

Stem cells in bone diseases: current clinical practice.

Introduction Bone is an obvious candidate tissue for stem cell therapy. This review provides an update of existing stem cell-based clinical treatments for bone pathologies. Sources of data A systematic computerized literature search was conducted. The following databases were accessed on 10 February 2011: NIH clinical trials database, PubMed, Ovid and Cochrane Reviews. Areas of agreement Stem cell therapy offers new options for bone conditions, both acquired and inherited. Areas of controversy There is still no agreement on the exact definition of 'mesenchymal stem cells'. Consequently, it is difficult to appreciate the effect of culture expansion and the feasibility of allogeneic transplantation. Growing points Based on the sound foundations of pre-clinical research, stem cell-based treatments and protocols have recently emerged. Areas timely for developing research Well-designed prospective clinical trials are needed in order to establish and develop stem cell therapy for bone diseases. Beyth S, Schroeder J, Liebergall M.

Efficacy of Treatment of Trochanteric Bursitis: A Systematic Review.

Efficacy among surgical techniques varied depending on the clinical outcome measure, but all were superior to corticosteroid therapy and physical therapy according to the VAS and HHS in both comparison studies and between studies. This systematic review found that traditional nonoperative treatment helped most patients, SWT was a good alternative, and surgery was effective in refractory cases.

Surgical treatment of displaced medial clavicle fractures using a small T-shaped plate and tension band sutures.

The surgical treatment of medial clavicle nonunion is associated with high complication and failure rates, particularly with regard to metal work migration. Therefore, we describe a simple surgical procedure for displaced medial clavicle fractures using a small T-shaped plate and multiple tension band sutures. After stabilizing the medial clavicle fracture using a small nonunion for the distal radius, our simple technique for preventing high complication and failure rates is performed easily and effectively, with sufficient tension band sutures.

Descending Geniculate Artery: The Ideal Recipient Vessel for Free Tissue Transfer Coverage of Below-the-Knee Amputation Wounds.

The descending geniculate artery has received notoriety as the source vessel of the medial femoral condyle vascularized bone flap in recent years. Its size and location enable it to serve as a useful recipient vessel in free flap reconstruction about the knee. It is particularly useful in coverage of unstable below-the-knee amputation stumps when recipient vessels are limited. It provides the ease and convenience of two-team surgery in the supine position and its distal position permits convenient and distal insetting of the transferred flap of choice. A discussion of its use in this setting and exemplary cases are provided. Higgins JP. J Reconstr Microsurg. 2011 Aug 2. [Epub ahead of print] PMID: 21811968

IT solution to improve hospital workflow and schedules (including the OR)

"The benefit of this system, over a human-run system, is that it is more accurate, efficient and quicker and is able to adapt to any changes in the availability of staff, equipment, or delays immediately.

"For example, surgical procedures can go overtime, staff can be off sick and equipment can fail, all of which can cause delays. This system is able to automatically revise the schedule of tasks in a way that maintains efficiency and assists in the decision making process." MedicalXpress

Anterior shoulder instability: a review of pathoanatomy, diagnosis and treatment.

The glenohumeral joint is inherently predisposed to instability by its bony architecture. The incidence of traumatic shoulder instability is 1.7% in the general population. Associated injuries to the capsulolabral structures of the glenohumeral joint have been described and may play a role in predicting recurrent instability. Advanced imaging, computed tomography or MRI may be necessary to adequately evaluate for associated glenohumeral pathology. Treatment algorithms have traditionally included a period of non-operative management in all patients, however young athletic patients may often benefit from early operative treatment. Various open and arthroscopic surgical options exist to address anterior glenohumeral instability. Bony injuries including bony Bankart lesions and Hills Sachs lesion have been implicated in failed surgical management using techniques that address only the soft tissues. An individualized treatment approach, based upon the patient's injury pattern and expectations, will likely lead to the most successful outcome. Dumont GD, Russell RD, Robertson WJ.

Apps for surgeons and the operating room

The explosive growth of medical applications for smartphones, launched by the  debut of the innovative Apple iTunes App store in 2008, promises to fundamentally change the physician’s tool set. While many specialties have always been heavily dependent on technology, such as radiology and cardiology, the ubiquity of these small, interconnected computers means that every physician will soon have access to a broad array of software and hardware to help them perform their daily work. iMedicalApps

New composite material may restore damaged soft tissue

Biomedical engineers at Johns Hopkins have developed a new liquid material that in early experiments in rats and humans shows promise in restoring damaged soft tissue relatively safely and durably. The material, a composite of biological and synthetic molecules, is injected under the skin, then "set" using light to form a more solid structure, like using cold to set gelatin in a mold. The researchers say the product one day could be used to reconstruct soldier's faces marred by blast injuries. Eurekalert!

Accuracy of intra-articular injections of the glenohumeral joint through an anterior approach: arthroscopic correlation.

The results of this study show that an anterior injection into the glenohumeral joint can be accurately placed without radiographic assistance using standard landmarks. The technique used is similar to making a standard rotator interval portal during shoulder arthroscopy; therefore, it is most successful in the hands of experienced shoulder arthroscopists.  Kraeutler MJ, Cohen SB, Ciccotti MG, Dodson CC.

Extensor pollicis longus rupture after distal radius fracture: Results of reconstruction by transposition of the extensor indicis tendon and postoperative dynamic splinting.

Injury of the extensor pollicis longus tendon is one of the commonest extensor tendon injuries after distal radius fracture. In 2003-2005 we performed extensor indicis transfer in 31 patients with loss of function of the EPL tendon and postoperative dynamic splinting. In 25 patients, a distal radius fracture managed surgically led to the EPL rupture (wire internal fixation in 23 patients, plate internal fixation in 2 patients). In 6 patients, the cause was a distal radius fracture treated conservatively. Out of our 25 followed-up patients, 9 (36%) had a very good and 15 (60%) a good result in the Geldmacher score. We did not identify any re-rupture. In injuries of the extensor pollicis tendon, transposition of the extensor indicis tendon is a simple and uncomplicated procedure. Considerable improvement of thumb extension can be achieved through this substitution repair. Figl M, Mayer M, Lederer S, Bogner R, Leixnering M. Wien Klin Wochenschr. 2011 Aug 3.
