Pseudoaneurysm of the profunda femoris artery following a long anterograde intramedullary nail for an unstable intertrochanteric hip fracture: A case report and review of the literature
The incidence of hip fracture has been on the increase and projected to be higher than 6million cases by the year 2050. Complications due to surgical fixation of hip fractures include, but are not limited to, infection, mal or nonunion, avascular necrosis, hardware failure, neurovascular injuries, and death. Vascular complications after surgical hip fracture fixation are very rare. We report a patient who developed Pseudoaneurys...
Elastomeric Osteoconductive Synthetic Scaffolds with Acquired Osteoinductivity Expedite the Repair of Critical Femoral Defects in Rats
Regenerative medicine aspires to reduce reliance on or overcome limitations associated with donor tissue-mediated repair. Structural bone allografts are commonly used in orthopedic surgery, with a high percentage of graft failure due to poor tissue integration. This problem is aggravated among elderly, those suffering from...
Biomechanical investigation of a novel ratcheting arthrodesis nail
Knee or tibiotalocalcaneal arthrodesis is a salvage procedure, often with unacceptable rates of nonunion. Basic science of fracture healing suggests that compression across a fusion site may decrease nonunion. A novel ratcheting arthrodesis nail designed to improve dynamic compression is mechanically tested in comparison to
Cell therapy in bone healing disorders
In addition to osteosynthetic stabilizing techniques and autologous bone transplantations, so-called orthobiologics play an increasing role in the treatment of bone healing disorders. Besides the use of various growth factors, more and more new data suggest that cell-based therapies promote local bone regeneration.
Medial pelvic migration of the lag screw in a short gamma nail after hip fracture fixation: A case report and review of the literature
Hip fractures are a common injury among the elderly. Internal fixation with an intramedullary (IM) system has gained popularity for the treatment of intertrochanteric femur fractures. Multiple complications associated with IM fracture fixation have been described, however, we report a rare complication of medial pelvic migration of the...
Upper Extremity Stress Fractures and Spondylolysis in an Adolescent Baseball Pitcher With an Associated Endocrine Abnormality: A Case Report
Lower extremity stress fractures are relatively common among competitive athletes. Stress fractures of the upper extremity, however, are rare and most have been reported in the literature as case reports. We present a case of an adolescent baseball pitcher who had both proximal humeral and ulnar shaft stress fractures, as well...
Management of type II superior labrum anterior posterior lesions: A review of the literature
Superior labrum anterior and posterior lesions were first described in 1985 by Andrews et al. and later classified into four types by Synder et al. The most prevalent is type II which is fraying of the superior glenoid labrum with detachment of the biceps anchor. Superior labrum anterior posterior (SLAP) lesions can also be associated with...
Treatment of chronic lateral ankle instability: A modified broström technique using three suture anchors
Ankle sprains are very common injuries seen in the athletic and young population. Majority of patients will improve with a course of rest and physical therapy. However, with conservative management about twenty percent of all patients will go on to develop chronic lateral ankle instability. This manuscript describes our...
Sustained and Localized In Vitro Release of BMP-2/7, RANKL and Tetracycline from FlexBone, an Elastomeric Osteoconductive Bone Substitute
We tested the hypothesis that synthetic composites containing a high percentage of osteoconductive biominerals well-integrated with a hydrophilic polymer matrix can be engineered to provide both the structural and biochemical framework of a viable synthetic bone substitute. FlexBone, an elastic hydrogel-mineral...
Intermediate Outcomes After Primary Traumatic Anterior Shoulder Dislocation in Skeletally Immature Patients Aged 10 to 13 Years
A paucity of literature exists regarding the outcome of skeletally immature patients who sustain a primary traumatic anterior shoulder dislocation. Most published results focus on adolescents and young adults, using recurrent dislocation/instability as a determinant of outcome, rather than a validated quality of life measurement...
