PURPOSE To analyze the relative position of the mandibular foramina (MnFs) in patients diagnosed with skeletal class III malocclusion. MATERIALS AND METHODS Computed tomography (CT) images were collected from 85 patients. The vertical lengths of each anatomic point from the five horizontal planes passing through the MnF were measured at the coronoid process, sigmoid notch, condyle, and the go...

Seven patients with nonunion of the scaphoid were treated by a limited approach combining a palmar wedge graft with insertion of a dorsal (retrograde) Herbert screw through small incisions. All patients had palmar bone deficiency and a 'difficult' proximal fragment. They were followed up for a minimum of 12 months (12 to 38). Radiological union was achieved in all. In five patients correction o...

PURPOSE Lengthening of the mandible by distraction osteogenesis is the preferred method for treatment of hemifacial microsomia in children. Use of an intraoral distraction technique and horizontal oblique ramus osteotomy in such patients is presented. PATIENTS AND METHODS Mandibular ramus lengthening was performed in 11 patients aged 6 to 12 years with hemifacial microsomia. During the age of...

BACKGROUND Mandibular reconstruction is performed after segmental mandibulectomy, and precise repositioning of the condylar head in the temporomandibular fossa is essential for maintaining preoperative occlusion. METHODS In cases without involvement of soft tissue around the mandibular bone, the autopolymer resin in a soft state is pressed against the lower border of the mandible and buccal a...

The blood supply of the Papillary Muscle (PM) of the left ventricle, cranial (PM) and caudal (PM), in Hereford cattle was studied. The results obtained from the dissection of 50 hearts injected with neoprene latex, indicated that the cranial PM is supplied by collateral of the Ramus descendens paraconalis in all cases, alone or together with vessels from the Ramus circumflexus of the Arteria co...

Early failure of hip resurfacing has been attributed to component malposition and other factors. Accurate placement of the femoral guide pin is challenging with commercial guides, and computer navigation adds considerable cost to the procedure. Precise pin placement can be achieved by drilling a 2.8-mm pin across the hip joint in a retrograde fashion similar to placing a dynamic hip screw pin. ...

BACKGROUND The dynamic compression screw is a plate and screws implant used to treat fractures of the distal femur. The Biomet Matthews Nail is a new retrograde intramedullary nail designed as an alternative surgical option to treat these fractures. The objective of this study was to assess the comparative endurance of both devices. METHOD The dynamic compression screw (DCS) and Biomet Matthe...

The objective of this study was to compare retrograde intramedullary femoral nailing with supracondylar locked screw-plate fixation for the treatment of periprosthetic femur fractures following total knee arthroplasty. Time to union and full weight bearing were the primary study outcomes, with perioperative blood loss, need for transfusion, need for revision surgery, and infection being the sec...
