Biomechanical Considerations for Surgical Stabilization of

Feb 23 2017The midshaft of far cortical locking screws is modified such that the screws lock into the far cortex and the plate but bypass the near cortex The increased working length of the screw results in a reduction in stiffness and allows for parallel interfragmentary motion at the near cortex which promotes callus formation and fracture healing

Far Cortical Locking Can Improve Healing of Fractures

This study evaluated healing of fractures stabilized with a locked plating construct and a far cortical locking construct which is a modified locked plating approach that promotes interfragmentary motion The study tested whether far cortical locking constructs can improve fracture-healing compared with standard locked plating constructs

Antegrade nailing for Simple transverse distal 1/3 fractures

Simple transverse non-comminuted fractures are stable and fracture healing may be enhanced by dynamic locking Comminuted fractures require a length stable construct so stable locking is mandatory Slotted locking holes can be used for dynamic locking while small circular holes are used for static locking

ORIF

Subtrochanteric fractures present a particular problem in terms of fracture reduction and alignment Due to the strong iliopsoas muscle pull the proximal fragment is flexed and externally rotated and therefore difficult to control In an open plating technique a preliminary reduction can be undertaken to facilitate the final reduction

EFFECT OF FAR INFRARED RADIATION ON BONE HEALING

It states that far infrared light therapy can accelerate the wound-healing response for damaged tissue It cites the near infrared light which is used in sports medicine to relieve muscle Bone Repair on Fractures Treated with Osteosynthesis ir Laser Bone Graft and Guided Bone Regeneration: Histomorfometric Study

Dynamic locking screw improves fixation strength in

The novel dynamic locking screw (DLS) was developed to improve bone healing with locked-plate osteosynthesis by equalising construct stiffness at both cortices Due to a theoretical damping effect this modulated stiffness could be beneficial for fracture fixation in osteoporotic bone Therefore the mechanical behaviour of the DLS at the screw–bone interface was

proximal humeral fractures

Distal Femoral Fractures –Proximal fixation with far cortical locking screws to dynamize bridge-plate fixation was safe and produced better healing than did standard locking implants investigated in previous studies While the majority of these fractures can be successfully treated with initial mobilization in a sling followed by return

Suitability of DCPs with screw locking elements to allow

Sep 19 2012Group 1 used for comparison purposes represents a system comprised of a Locking Compression Plate (LCP) and eight locking screws Groups 2 and 3 represent a system comprised of a DCP plate with eight cortical screws and two SLEs placed on the screws furthest from (group 2) and nearest to (group 3) the fracture

Avulsion fracture: How is it treated?

Treatment of an avulsion fracture typically includes resting and icing the affected area followed by controlled exercises that help restore range of motion improve muscle strength and promote bone healing Most avulsion fractures heal very well without surgical intervention

A Biomechanical Comparison of Standard versus Far Cortical

locking screws or far cortical locking screws in the diaphysis (holes 3 5 7 and 9) All plates were fixed distally with 5 standard locking screws A distal femoral fracture was then cre-ated with a 1-cm lateral and 3-cm medial gap simulating an extra articular periprosthetic fracture

Far cortical locking can reduce stiffness of locked plating constructs while retaining construct strength Bottlang M Doornink J Fitzpatrick D C Madey S M J Bone Joint Surg Am 2009 Aug 05 A nonlocking end screw can decrease fracture risk caused by locked plating in the osteoporotic diaphysis

Far Cortical Locking Can Improve Healing of Fractures

far cortical locking constructs can improve fracture-healing compared with standard locked plating constructs Methods: In an established ovine tibial osteotomy model with a 3-mm gap size twelve osteotomies were randomly stabilized with locked plating or far cortical locking constructs applied medially The far cortical locking constructs were

Evidence for success with locking plates for fragility

Using Metal Plates to Stabilize Finger Fractures

But other studies show far cortical locking stimulates bone growth by allowing a tiny bit of movement within the bone fragments That movement signals bone to form the needed callus to stabilize the fracture The major limitations of locked plating are the tendency to be too stiff to allow fracture healing
