Antegrade telescoping rods have been introduced for use in pediatric patients with osteogenesis imperfecta (OI) to decrease the incidence of long-bone fractures and to correct and prevent deformities. Recent studies have documented failures of telescoping intramedullary rods due to inadequate distal fixation. The purpose of this study was to evaluate the pullout strength of distal fixation of t...

BACKGROUND Fixation strength of metal and bioabsorbable interference screws has not been evaluated while varying the anterior cruciate ligament graft tension angle. HYPOTHESIS There is no difference in fixation strength between 2 types of interference screws for anterior cruciate ligament graft fixation while the graft tension angle is varied relative to the femoral tunnel. STUDY DESIGN Con...

BACKGROUND The aim of the present study was to investigate the safety of bioabsorbable plates and screws in humans. METHODS For this purpose, an implant system based on [poly(lactic-co-glycolic acids)(85:15)] was designed. The system was tested for pH, temperature, and swelling and then its surface morphology was analyzed for surface porosity using environmental electron microscopy. Then, the...

Placing a coronary stent during angioplasty minimizes reduces of acute vessel occlusion [1] and restenosis [2]. Although permanent metallic stents are effective in preventing recoil and late restenosis after coronary angioplasty, they continue to have limitations such as stent thrombosis and mismatch of the stent to the vessel size. In-stent restenosis is the major shortcoming of conventional (...

Bioabsorbable implants are very frequently used to treat rotator cuff and shoulder labrum injuries. Many researchers have observed small areas of osteolysis after treating pathological conditions of the shoulder using bioabsorbable anchors. Biological and mechanical theories have been put forward to account for the osteolysis caused by these materials. The case of a patient who was simultaneous...

Bioabsorbable suture anchors are commonly used for arthroscopic repair of rotator cuff and labrum lesions. They provide soft-tissue attachment to bone. They have been introduced to avoid complications such as artefacts on MRI scans, commonly seen with metal anchors. However, bioabsorbable implants may lead to other problems such as local osteolysis, cyst formation, soft tissue inflammation and ...

507 them just had fluid accumulation and no foreign body granuloma. This rarity of the foreign body granuloma formation makes our case worthy of report. In conclusion, although bioabsorbable implants have many advantages, we suggest paying considerable attention to their disadvantages such as their low strength and tendency to cause foreign body reactions. Moreover, hands require the ability to...

INTRODUCTION The pursuit of bone fixation systems capable of affording appropriate stability for osteosynthesis has gone through several stages from the use of metal wires, plates, and screws to the current stage of bioabsorbable systems. In our Pediatric Neurosurgery Service and Craniofacial Surgery Unit we began employing these systems in June 1997. The object of this paper is to present a re...

INTRODUCTION Anterior Cruciate Ligament (ACL) is as one of the most frequently injured ligaments in the modern contact sports scenario. Graft fixations can be achieved during anterior cruciate ligament (ACL) reconstructions by using either bioabsorbable screws or metal screws. The objective of this study was to compare the functional outcomes after bioabsorbable and metallic interference screw ...

PURPOSE To evaluate the extent of femoral tunnel widening after quadrupled hamstring anterior cruciate ligament reconstruction using femoral cross pin fixation in contrast to bioabsorbable screw fixation augmented with Endopearl. METHODS 16 patients underwent cross pin femoral fixation and the next 15 underwent bioabsorbable screw fixation augmented with Endopearl. The patients were evaluated...
