TKR: Femoral Component Box Cut:
– Box Cut: – ensure that box cutting jig is placed flush on anterior and distal femoral surfaces; – box cutting jig is centered over the intercondylar notch (or IM drill hole); – if the knee has … Read more

Brachial Artery
– See: – Arteries of the Upper Limb; – Profunda Brachi; – Anatomy: – brachial artery originates at the lateral border of teres major muscle & courses down anterior humerus posterior to bicipital aponeurosis; – brachial artery has three main braches, of which profunda brachi … Read more

Both Bone Forearm Frx: Post Op Care
– Assessment of Reduction: – amount of radial bow is determined by drawing a line from the biciptial tuberosity to the ulnar aspect of the distal radius; – at the point of maximal radial bow, measure the distance of a line drawn perpendicular to the first line; – Frx Malunion: … Read more
Bone Patellar Bone Reconstruction: Graft Fixation
– Discussion: – there is inherent graft weakness during period after implantation when allograft& autograft tissues undergo necrosis, revascularization, and cellular proliferation; – weakest link initially is graft fixation site; – it is important to achieve strong fixation initially; … Read more
Bone Patellar Bone Repair: Graft Insertion
– Technique: – at this point, No 2 Ethibond stay sutures will have already been passed thru drill holes made in each bone plug; – proposed tibial bone plug should have an additional stay suture passed thru the bone-tendon interval (as a safety feature should the interference screws … Read more
Bone Patellar Bone ACL Reconstruction

Bone and Fracture Healing
– See: Bone Topics – Discussion: – woven bone healing: – ref: Distal radial fractures heal by direct woven bone formation – stages of enchondral bone healing: – hematoma / inflammation: – shortest stage of fracture healing – disruption of vascular flow through the marrow and periosteum … Read more
Bone Graft Menu
– Discussion: (see fracture healing and management of tibial bone defects) – autograft: bone graft harvest techniques – allografts – induced membrane technique – bone marrow aspirates: – in order to maximum the concentration of osteoblast precursors, no more than 2 cc should be … Read more
Bone Grafting for Tibial Fracture
– See: Tibial Non Unions – Discussion: – up to 60% of high energy open tibial will fail to heal by 20 weeks, and therefore MD must decide which fractures require early bone grafting and which do not; – large tibial defects: – w/ defects less than … Read more
