New pediatric supracondylar humerus fractures CPG At their meeting on Sept. 24, 2011, the AAOS Board of Directors approved a new clinical practice guideline (CPG) on the treatment of pediatric supracondylar humerus fractures. This is the third CPG to focus on a primarily pediatric condition.

Supracondylar fractures of the humerus are widely considered to be the most common fracture of the elbow in children (Fig. 1). Approximately 3 percent of all fractures in children are supracondylar fractures. They often result from trauma to the elbow, most often due to a fall from a height or related to sports or leisure activities.  AAOS

Multiple associated injuries are common with spine fractures during war.

Spine fractures sustained in OEF and OIF have high rates of AIs. Musculoskeletal AIs are the most common, but visceral injuries adjacent to the spine fracture frequently occur. Multiple spine injuries are more prevalent after military trauma. Patzkowski JC, Blair JA, Schoenfeld AJ, Lehman RA, Hsu JR; Skeletal Trauma Research Consortium (STReC). Spine J. 2011 Nov 2.

Simplified Model to Predict Stress Fracture in Young Elite Combat Recruits.

The purpose of the study was to develop a simple prediction model for stress fractures (SF) in young male recruits in order to identify risk factors for SF. Data were collected from 57 young (18.5±0.5yrs) males prior to elite combat basic training (BT). Measurements included anthropometric variables, blood samples, fitness tests, bone quality (pQCT), psychological assessment, nutritional habits, and history of physical activity. A medical evaluation was done periodically. Moran DS, Finestone A, Arbel Y, Shabshin N, Laor A. J Strength Cond Res. 2011 Nov 4. [Epub ahead of print] PMID: 22067250

Surgical interventions for diaphyseal fractures of the radius and ulna in children.

There is a lack of evidence from randomised controlled trials to inform on when surgery is required and what type of surgery is best for treating children with fractures of the shafts of the radius, ulna or both bones. Abraham A, Kumar S, Chaudhry S, Ibrahim T. Cochrane Database Syst Rev. 2011 Nov 9;11:CD007907. PMID: 22071838

Surgical versus non-surgical interventions for treating patellar dislocation.

There is insufficient high quality evidence to confirm any significant difference in outcome between surgical or non-surgical initial management of people following primary patellar dislocation, and none examining this comparison in people with recurrent patellar dislocation. Adequately powered randomised, multi-centre controlled trials, conducted and reported to contemporary standards are recommended. Hing CB, Smith TO, Donell S, Song F. Cochrane Database Syst Rev. 2011 Nov 9;11:CD008106. PMID: 22071844

Effect of partial meniscectomy at the medial posterior horn on tibiofemoral contact mechanics and meniscal hoop strains in human knees.

From a biomechanical point of view, our in vitro study suggests that the medial joint compartment is not in danger of accelerated cartilage degeneration up to a resection limit of 20% meniscal depth and 10 mm width. Contact mechanics are likely to be more sensitive to partial meniscectomy at higher flexion angles, which has to be further investigated. Seitz AM, Lubomierski A, Friemert B, Ignatius A, Dürselen L. J Orthop Res. 2011 Nov 9.

Lubricin is expressed in chondrocytes derived from osteoarthritic cartilage encapsulated in poly (ethylene glycol) diacrylate scaffold.

The results showed an increased expression of lubricin in explanted tissue and in monolayer cells from normal cartilage, and a decreased expression of lubricin in OA cartilage. The chondrocytes from OA cartilage after 5 weeks of culture in hydrogels (PEGDA) showed an increased expression of lubricin compared with the control cartilage. The present study demonstrated that OA chondrocytes encapsulated in PEGDA, grown in the scaffold and were able to restore lubricin biosynthesis. Thus our results suggest the possibility of applying autologous cell transplantation in conjunction with scaffold materials for repairing cartilage lesions in patients with OA to reduce at least the progression of the disease. Musumeci G, Loreto C, Carnazza ML, Coppolino F, Cardile V, Leonardi R. Eur J Histochem. 2011 Sep 21;55(3):e31.

Cone-beam computed tomography arthrography: an innovative modality for the evaluation of wrist ligament and cartilage injuries

Cone-beam computed tomography (CBCT) has become an important modality in dento-facial imaging but remains poorly used in the exploration of the musculoskeletal system. The purpose of this study was to prospectively evaluate the performance and radiation exposure of CBCT arthrography in the evaluation of ligament and cartilage injuries in cadaveric wrists, with gross pathology findings as the standard of reference.   Reeta Ramdhian-Wihlm, Jean-Marie Le Minor, Matthieu Schmittbuh, Jeremy Jeantroux, Peter Mac Mahon, Francis Veillon, Jean-Claude Dosch, Jean-Louis Dietemann, Guillaume Bierry.

Evaluation of ultrasound-guided diagnostic local anaesthetic hip joint injection for osteoarthritis.

The diagnosis of hip osteoarthritis is often complicated by co-existing pathology in the knee and spine, and mismatch between clinical and radiological signs. Temporary pain relief from a local anaesthetic injection into the hip joint has been reported to help localise symptoms, reducing the risk of unnecessary surgery being performed. We hypothesize that good surgical outcome is predicted by good analgesia following diagnostic injection, and that alternative pathology is present when there is no response to injection. Yoong P, Guirguis R, Darrah R, Wijeratna M, Porteous MJ. Skeletal Radiol. 2011 Nov 10.

Scientists identify proteins that direct bone demolition

Scientists at Washington University School of Medicine in St. Louis have identified four proteins that supervise bone demolition, directing the destructive work of cells known as osteoclasts. The finding will help efforts to prevent bone loss and weakening caused by osteoporosis, cancer and other conditions.

“We currently treat these disorders with drugs that inhibit osteoclasts,” says lead author Carl DeSelm, an MD/PhD student. “The ideal drug would slow down osteoclasts when they get out of control but still allow some breakdown so that renewed bone can be built in its place.” The findings appear in Developmental Cell.

ORBIT 3D X-ray Scanner Eliminates the C-Arm From the Operating Room

Researchers at the Fraunhofer Institute are working on the ORBIT, a 3D X-ray scanner that overcomes many of the disadvantages of traditional C-arms. When using a C-arm, procedures need to be paused to make room and move the device in, which will circle around the patient capturing the 3D image. The ORBIT is an open system in which the X-ray source follows a circular path above the operating table. medGadget

Surgical techniques and therapeutic results of anatomical reconstruction of coracoclavicular ligaments for acromioclavicular joint dislocations

Generally, the surgical treatment for traumatic acromioclavicular joint dislocation is recommended for type 5 according to Rockwood’s classification. We believe that anatomical restoration of coracoclavicular ligament could best restore the function of the acromioclavicular joint. We attempted to correctly reconstruct the anatomy of the coracoclavicular ligament (trapezoid and conoid ligaments) in which the ipsilateral palmaris longus tendon and Endobutton were used as the reconstructing ligament and fixation material, respectively.

ACR: Steroids Tied to Bone Death (CME/CE)

Even short courses of glucocorticoids in conditions such as lupus, rheumatoid arthritis, and many other diseases can be associated with the development of osteonecrosis, a researcher cautioned here.


For instance, exposure to these drugs for less than 30 days was associated with an odds ratio of 3.8 (95% CI 2.1 to 6.8) for osteonecrosis compared with no exposure, Steven C. Vlad, MD, of Boston University School of Medicine, reported at the annual meeting of the American College of Rheumatology. MedPage Today

Atraumatic Osteonecrosis of the Distal Radius and Ulna: Case Series and Review

Atraumatic multifocal osteonecrosis is defined as the occurrence of this entity in 3 or more anatomic locations, and is rare. We identified 6 patients with osteonecrotic lesions in the distal ulna, radius, or both. The purposes of this study were to describe the clinical manifestations of atraumatic multifocal osteonecrosis affecting these bones, to identify risk factors for developing the disease in these locations, and to evaluate the success of treatment by percutaneous drilling.

AHRQ: Big Jump in Knee Replacement Surgery

 Knee replacement surgery among middle-aged men and women increased 2.5-fold from 1997 to 2009, new figures from the Agency for Healthcare Research and Quality (AHRQ) show.

The rate of hospitalizations for knee arthroplasty for women ages 45 to 64 increased 157%, from 16 per 10,000 people in 1997 to 42 for every 10,000 people in the U.S. in 2009.

For men, the rate jumped 144%, from 11 stays to 28 stays per 10,000 people over the same time period, according to a report released last week by AHRQ on statistics in hospital-based care. MedPage Today
