PGE 2 and BMP-2 in bone and cartilage metabolism: 2 intertwining pathways
Osteoarthritis and lesions to cartilage tissue are diseases that frequently result in impaired joint function and patient disability. The treatment of osteoarthritis, along with local bone defects and systemic skeletal diseases, remains a significant clinical challenge for orthopaedic surgeons. Several bone morphogenetic proteins (BMPs).
Assessment and management of chronic pain in patients with stable total hip arthroplasty
Total hip arthroplasty (THA) is one of the most successful operations that can restore function and relieve pain. Although a majority of the patients achieve significant pain relief after THA, there are a number of patients that develop chronic pain for unknown reasons. A literature search was performed looking for chronic pain after total
pHEMA-nHA Encapsulation and Delivery of Vancomycin and rhBMP-2 Enhances its Role as a Bone Graft Substitute
BACKGROUND: Bone grafts are widely used in orthopaedic procedures. Autografts are limited by donor site morbidity while allografts are known for considerable infection and failure rates. A synthetic composite bone graft substitute poly(2-hydroxyethyl methacrylate)-nanocrystalline hydroxyapatite (pHEMA-nHA) was previously...
Isolated Tear of the Pectoralis Minor Tendon in a High School Football Player
Multiple pectoralis major tendon tears have been reported in the literature; however, isolated rupture of the pectoralis minor tendon is rare and has been reported 3 times (4 patients).This article describes a case of an isolated pectoralis minor tendon tear in a male high school football player after a traumatic injury. The patient was injured while making a tackle and leading with his arm and chest. He presented with left anterior...
Anconeus Epitrochlearis as a Source of Medial Elbow Pain in Baseball Pitchers
Medial elbow pain is reported in 18% to 69% of baseball players aged of 9 and 19 years. This is due to the large valgus stresses focused on the medial side of the elbow during overhead activities. In overhead throwers and pitchers, pain can be attributed to valgus extension overload with resultant posteromedial impingement, overuse...
Intraspinal Penetrating Stab Injury to the Middle Thoracic Spinal Cord With No Neurologic Deficit
The annual incidence of traumatic spinal cord injury worldwide is estimated to be 35 patients per million. Nonmissile penetrating spinal injuries most commonly occur in the thoracic region, and the majority has neurologic deficits on admission. The management of patients who lack neurologic deficits is controversial due...
Evaluation of sterilization methods following contamination of hamstring autograft during anterior cruciate ligament reconstruction
PURPOSE: Inadvertent contamination of the hamstring autograft during ACL reconstruction is infrequent, but can result in significant complications. The purpose of this study is to evaluate bacterial contamination of hamstring autografts dropped onto the operating room floor and methods of graft decontamination.
Costal Cartilage Fractures and Disruptions in a Rugby Football Player
Costal cartilage fracture of the rib cage, or costochondral, is a rare sporting injury. For contact athletes, the instability of the rib cage may lead to potential serious complications, similar to rib fractures or thorax disruption. Most authors recommend initial conservative treatment with surgery reserved for only recalcitrant cases.
Use of the F-Tool for the Removal of a Bent Intramedullary Femoral Nail With a Sagittal Plane Deformity
Locked intramedullary nailing is the current standard of treatment for femoral shaft fractures and has low complication rates. Bent femoral intramedullary nails resulting from secondary trauma are rare and technically challenging. This article describes a case of a 36-year-old man who presented with a bent femoral intramedullary...
Entrapped periosteum preventing reduction of a Salter-Harris II distal tibial fracture in an adolescent patient. MRI and intra-operative findings
INTRODUCTION Physeal or growth plate injuries comprise 18% of all pediatric fractures, with Salter Harris type II as the most common type of fracture injury pattern ob-served in 61% of patients.The incidence of growth arrest is just over 1%, and the incidence of serious complications is less than 1%. Irreducible physeal fractures...
