The treatment of infected tibial nonunion usually includes a staged reconstruction protocol. We present 2 patients with tibial nonunion and plate loosening with oxacillin-resistant Staphylococcus aureus infection. The patients were treated using the removal of the plate, radical debridement, and implantation of gentamycin-impregnated cement beads during the first stage. During the second stage,...

Bisphosphonates, used to treat diseases exhibiting increased osteoclast activity, reduce longitudinal bone growth through an as yet undefined mechanism. Pamidronate, an aminobisphosphonate, was given weekly to mice at 0, 1.25, or 2.50 mg/kg/wk beginning at 4 weeks of age. At 12 weeks of age, humeral length, growth plate area, regional chondrocyte cell numbers, chondrocyte apoptosis, TRAP staine...

A finite element analysis was carried out to determine the optimal plate placement for pantarsal arthodesis. Three different plate placement scenarios were considered: cranial, lateral, and caudal. Under similar loading conditions, the finite element results showed that the cranial and lateral plates experienced stresses surrounding the metatarsal screws which may indicate screw loosening or fa...

Conventional surgical approach for cyst enucleation is removal of buccal compact bone plate, which often results in remarkable bone loss and subsequent mucosal recession. This report presents one case of residual mandibular cyst enucleation and one case of apicoectomized mandibular molar, both treated with the bony lid approach. A window of buccal compact bone was precisely created using an ele...

Low birth weight is associated with reduced bone mass and density in adult life. However, effects of maternal hypoxia (MH) on offspring bone development are not known. Objective. The current study investigated the effects of fetal growth restriction induced by MH during the last half of gestation on bone structure and volume in the offspring of the fetus near term and the pup in adolescence. Me...

OBJECTIVES Surgical treatment of proximal humerus fractures can be challenging due to osteoporosis. The weak bone stock makes stable implant anchorage difficult, which can result in low primary stability. Accordingly, significant failure rates, even with modern locking plates, are reported in the literature. Intraoperative knowledge of local bone quality could be helpful in improving results. T...

We conducted a study to evaluate the congruency of fit of current scapular plate designs. Three-dimensional image-processing and -analysis software, and computed tomography scans of 12 cadaveric scapulae were used to generate 3 measurements: mean distance from plate to bone, maximum distance, and percentage of plate surface within 2 mm of bone. These measurements were used to quantify congruenc...

We describe a case of radiation-associated fracture nonunion of the clavicle, which was treated by locking plate fixation and autologous bone grafting. The patient was a 67-year old man who received 70 Gy radiation therapy to treat nasopharyngeal carcinoma. Eight years later, he suffered a pathological fracture of the right clavicle. One year after the fracture, surgical treatment was performed...

OBJECTIVES The purpose of this study was to compare the biomechanical properties of posterolateral antiglide plating and lateral locked plating for fixation of displaced short oblique fractures of the fibula in osteoporotic bone. METHODS Short oblique fractures of the distal fibula at the level of the syndesmosis were simulated with a fibular osteotomy and ligamentous sectioning in 18 paired ...

A review of the literature in 2002, analyzing 13 articles with 895 tibial shaft fractures treated by cast immobilization, fixation with plate and screws, and reamed or unreamed intramedullary nailing, concludes that the combined incidence of delayed union and nonunion was lower with operative, surgical treatment especially with plate osteosynthesis, than with closed treatment. This incidence wa...
