![]() Bone is covered by periosteum, except at the joints, where it is covered with cartilage. Thick outer cortex surrounds cancellous (or trabecular) bone, and both contribute to bone strength. Hairline fracture: nondisplaced fracture with minimal separationĪvulsion fracture: fragment pulled away from bone at tendinous and ligament insertion (commonly at tuberosity)Īpophyseal fracture: at growth centers such as ischial tuberosity and medial epicondyle commonly avulsion fracturesīone is composed of calcium hydroxyapatite on a matrix of collagen and other proteins. Occult fracture: suspected but nonvisualized fracture on plain radiograph demonstrated by 99m technetium (Tc) methylene diphosphonate (MDP) scintigraphy or magnetic resonance imaging (MRI) Pseudofracture: fissure like defects in osteomalacia (Looser zones) Salter-Harris fracture: fractures involving growth plate Intraarticular fracture: fracture line extends into joint Pathologic fracture: fracture superimposed on underlying bone disease Insufficiency fracture: normal muscular stress applied to abnormal bone (e.g., osteoporotic vertebral fracture) Intraarticular extension of fracture lineįatigue fracture: abnormal muscular stress applied to normal bone (e.g., march fracture) Overriding: overlap of fragments (bayonet apposition) Describe the direction of the fracture line: transverse, oblique, spiral, longitudinalĬomminuted fracture (more than two fragments): T-, V-, Y-shaped patterns, butterfly fragments, segmentalĪpposition and alignment: defined in relation to distal fragmentsĭisplacement (e.g., medial, lateral, posterior, anterior)Īngulation (e.g., medial, lateral, posterior, anterior) Use anatomic landmarks for description (e.g., fracture near greater tuberosity). In long bones, divide the shaft into thirds (e.g., fracture distal third of femur).

There may be a “pickup fee” (equivalent to a delivery fee for pickup orders) on your pick up order that is typically $1.99 for non-Instacart+ members.With an optional Instacart+ membership, you can get $0 delivery fee on every order over $35 and lower service fees too. 100% of your tip goes directly to the shopper who delivers your order. It’s a great way to show your shopper appreciation and recognition for excellent service. Tipping is optional but encouraged for delivery orders.Orders containing alcohol have a separate service fee. Service fees vary and are subject to change based on factors like location and the number and types of items in your cart.Fees vary for one-hour deliveries, club store deliveries, and deliveries under $35. Delivery fees start at $3.99 for same-day orders over $35. ![]() Here's a breakdown of Instacart delivery cost: ![]()
