Vertebral Osteomyelitis.

Unlabelled: A report of an instance of vertebral osteomyelitis secondary to an uncommon pathogen, .

Summary: is a rapidly growing nontuberculous osteomyelitis which is typically nonpathogenic with only four reported cases of human infection. Diagnosing infections related to nontuberculous mycobacteria (NTM) is difficult and can often be delayed as conventional microbiologic tests are inadequate.

Clinical Outcomes of Open Subpectoral Biceps Tenodesis with Cortical Button Fixation.

Background: Open subpectoral biceps tenodesis (OSBT) with cortical button fixation can deliver acceptable results for long head of the biceps (LHB) pathology with the benefit of smaller bone tunnel diameter and a potential reduced risk of postoperative humeral shaft fracture. However, functional outcomes and complications of a button-only technique with a small diameter tunnel in the subpectoral region have not been studied sufficiently.

Purpose: We sought to determine whether OSBT with cortical button fixation results in significant functional improvements from preoperative to final follow-up.

The relationship of pelvic incidence to post-operative total hip arthroplasty dislocation in patients with lumbar fusion.

Purpose: To determine if lumbar fusion increases the risk of dislocation following total hip arthroplasty (THA) via a posterior approach and to investigate anatomic variables associated with this increased risk.

Methods: Five-year retrospective review of THAs performed through a posterior approach identifying cases of post-operative dislocation. Patients were grouped into those with or without previous lumbar spine fusion.

The Impact of Body Mass Index on Outcomes Following Open Sub-Pectoralis Major Biceps Tenodesis.

Purpose: Traditionally, biceps tenotomy has been recommended for obese, older, and less active patient populations, while tenodesis is preferred in younger, thinner, and more active individuals. In an effort to better understand the impact obesity has on the surgical management of long head of the biceps tendinopathy, the current study analyzed the effect body mass index had on surgical outcomes following open subpectoralis major biceps tenodesis.

Methods: Patients who underwent biceps tenodesis between June 2006 and December 2013 were identified from our institution's surgical database.

Coracoid Fracture Following Latarjet Failure A Case Report.

The Latarjet procedure involves the transfer of the coracoid process with its soft tissue attachments, thereby providing both bony and soft tissue articular reinforcement for glenohumeral stabilization. Most studies show positive outcomes with this procedure and complications at rates as low as 1%, predominately secondary to technical error. We present a case of recurrent anterior instability after two attempts at soft tissue stabilization (arthroscopic labral repair followed by open inferior capsular shift) in which an open Latarjet procedure was performed followed by subsequent revision secondary to coracoid autograft fracture.

Comparison of Collagen Graft Fixation Methods in the Porcine Knee: Implications for Matrix-Assisted Chondrocyte Implantation and Second-Generation Autologous Chondrocyte Implantation.

Purpose: To evaluate the fixation integrity at time zero of a type I/III collagen patch secured to a chondral defect in the porcine knee using methods typically employed in autologous chondrocyte implantation (ACI) and matrix-assisted chondrocyte implantation.

Methods: Twenty-four porcine knee specimens underwent a medial parapatellar arthrotomy. A prefabricated template was used to create cartilage defects of 2 cm(2) in the medial femoral condyle.

Subchondral Calcium Phosphate is Ineffective for Bone Marrow Edema Lesions in Adults With Advanced Osteoarthritis.

Background: Injury to subchondral bone is associated with knee pain and osteoarthritis (OA). A percutaneous calcium phosphate injection is a novel approach in which subchondral bone marrow edema lesions are percutaneously injected with calcium phosphate. In theory, calcium phosphate provides structural support while it is gradually replaced by bone.

The management of meniscal pathology: from partial meniscectomy to transplantation.

The management of meniscal pathology continues to evolve as researchers gain a better understanding of the role of the meniscus in normal knee kinematics. Evidence now supports retention or transplantation of meniscal tissue to maintain homeostatic knee mechanisms because the removal of meniscal tissue changes the contact stresses and leads to structural and biomechanical changes in the articular cartilage and the subchondral plate that predisposes the knee to the development of degenerative arthritis. Advances in repair techniques, biologic adjuvants, and progressive tissue-engineering strategies are rapidly adding to the surgeon's armamentarium when dealing with meniscal injury and insufficiency.

The effect of shoulder immobilization on driving performance.

Background: The purpose of this study was to evaluate the effect of sling immobilization on driving performance with use of a driving simulator.

Methods: This is a prospective trial with a cohort of 21 healthy volunteers comparing their driving ability with and without sling immobilization on their dominant (driving) extremity. Multiple variables, including number of collisions, off-road excursions, and centerline crossings, were measured with a validated driving simulator.

Outcomes of anterior cruciate ligament reconstruction in patients older than 50 years of age.

Background: Anterior cruciate ligament reconstruction (ACLR) has traditionally been reserved for young patients with functional instability. As the aging population continues to grow and embrace a more active lifestyle, it is important to determine if favorable outcomes of ACLR can be achieved in older adults.

Methods: Patients greater than 50 years of age undergoing ACLR between January 2001 and September 2006 were identified.

The reliability of nonreconstructed computerized tomographic scans of the abdomen and pelvis in detecting thoracolumbar spine injuries in blunt trauma patients with altered mental status.

Background: Computerized tomography, traditionally utilized to evaluate and detect visceral abdominal and pelvic injuries in multiply injured patients with altered mental status, also has been useful for detecting thoracolumbar spine fractures and dislocations. The purpose of the present study was to test the reliability of nonreconstructed computerized tomography of the abdomen and pelvis as a screening tool for thoracolumbar spine injuries in blunt trauma patients with altered mental status.

Methods: The study consisted of fifty-nine consecutive patients with altered mental status who were admitted to a Level-II trauma center.

Outpatient anterior cervical discectomy and fusion.

The study reported here examined patient safety and satisfaction in 56 patients with cervical radiculopathy secondary to foraminal stenosis or a herniated disc who underwent a total of 58 outpatient anterior cervical discectomy and fusion (ACDF) procedures with iliac crest bone graft or fibular allograft. Patients were discharged 0.8 hour to 6.
