In an experimental study that compared different implants, osteosynthesis with two LCPs was better than osteosynthesis with two DCPs, LC-DCPs or clamp rod internal fixation systems for the fixation of a simple oblique fracture in an equine long-bone model 0000018752 00000 n Bottlang M, Doornink J, Byrd GD, Fitzpatrick DC, Madey SM. 0000075220 00000 n The insertion torque was set at 3 Nm for the cortical screws and at 4 Nm for the locking screws. In the LCP, two central 4.5 mm cortical screws and 5.0 mm locking screws are used. There was no significant difference in compression between the first two compression screws in DCP and LCP (p=0.64, 0.92). Bridging of the growth plates by screws should be avoided in clinical cases, but in femoral fractures close to the distal metaphysis this is not always possible without severely compromising stability in large animals. This finding supports the idea of using far cortical locking screws 0000043675 00000 n 0000007225 00000 n In clinical cases, stripped cortical screws are commonly replaced with 6.5 mm cancellous screws 0000057162 00000 n Locking Compression Plate (LCP) The LCP permits use of angled conventional (compression) screws and fixed-angle locked screws through its patented combi-hole design (Figure 3). However, cortical screws were chosen in the present study because cancellous screws did not increase the fixation strength of an LC-DCP construct in an osteoporosis model Maximum excursion (in mm, median values for each construct) of the actuator for test cycle 5, 50 and 100.

In a study of newborn calves, 28 of 50 femoral fractures (56%) were located in the distal metaphysis 1) to distal (No. Received 2011 Oct 13; Accepted 2012 Aug 15. 0000081397 00000 n SAS® 9.1 (SAS Institute Inc., Cary, North Carolina, USA) was used to correct the data for repeated measures within a bone pair, and the animal from which the bones originated was defined as a random effect (PROC Mixed procedure). xref Although a preliminary trial established an insertion torque of 3 Nm for 4.5 mm cortical screws, a large number of cortical screws caused stripping of the thread in the soft bone of the distal metaphysis and epiphysis before the pre-set value was reached. An insertion torque sufficient to provide adequate stability for plate fixation in femurs of newborn calves could not be achieved reliably with 4.5 mm cortical screws. The number of loosened screws was much higher in the LC-DCP constructs which was associated with earlier implant failure. Background To compare the biomechanical in-vitro characteristics of limited-contact dynamic compression plate (LC-DCP) and locking compression plate (LCP) constructs in an osteotomy gap model of femoral fracture in neonatal calves. 0000077136 00000 n An insertion torque sufficient to provide adequate stability in femurs of newborn calves could not be achieved reliably with 4.5 mm cortical screws. A main limiting factor for the stability of both LC-DCP and LCP constructs was the distal fracture fragment. The maximum force was increased after each testing level, from 500 N in the first stage to 1000 N in the second stage followed by four subsequent steps of 250 N each to a maximum force of 2000 N. The axial excursion of the actuator of the testing machine was recorded at cycle 1, 50 and 100 during each level. This was inevitable in the LCP because of the predetermined entry angle of the locking screws, whereas it could have been partially prevented in the LC-DCP constructs by changing the entry angle of the cortical screws. The LCâDCPâR showed higher stiffness and resistance to failure, lower interfragmentary motion, and lower plate strain and stress compared to LCP. However, all 20 constructs were tested until failure and then compared with descriptive statistics. 0000045382 00000 n w@���, *Pe�@q� (���5ր�4c:�N �f��R�,�.$��1h3nc�c��] �AoAQ�7S�S Locking Compression Plate (LCP) Implants are intended for temporary ï¬xation, correction or stabilization of bones in various anatomical regions.

Gross displacement of the fragments (Figure Figure5).5). The rotational deviation of the distal fracture fragment in all the constructs was most likely the result of the eccentric orientation of the plate relative to the concavity of the femoral condyles (Figure LCPs are very high temperature materials that meet the requirements of large temperature excursions.

The design of the compression component of the âcombi-holeâ in the locking compression plate (LCP, Synthes Ltd.) was based on the long experience obtained from the DCP and was made to accommodate its instrumentation system. The plates were contoured to the craniolateral surface of the bones. Compression can be applied with an articulated tensioner or using eccentric screw placement in the holes. All three LC-DCP constructs failed before the 38th cycle of the 5th test level. Cortical screws in the metaphyses should be replaced by cancellous screws in further studies.

The most common cause of femoral fractures in calves is excessive traction during delivery, but trauma, such as the dam standing on the calf, and bovine viral diarrhoea (BVD) virus infection are other causes 6 appeared to be the centre of this rotational movement based on the observation that there were only minor changes in the appearance of screw hole No. case of LCP the ideal plate length can be determined by the plate span width and the plate screw density (20): the plate span width is the quotient of plate length divid-ed by overall fracture length. As a consequence of this weakness, no cortical screw in the distal fragment of the LC-DCP group remained firmly fixed after the second testing level.

The recently developed LCP has properties of the DCP and point contact fixator, which provide locking and compression via its combined hole. CONCLUSIONS: In a synthetic model, the LCP was mechanically superior to the DCP when used as a bridging plate and tested in axial compression. [34]. 0000040413 00000 n However, for better comparison of the two constructs, similar insertion angles were used in all screws. While failure occurred by loosening of the screws in the LC-DCP constructs, locking constructs failed by cutting large holes in the soft distal metaphyseal bone. Only the three intact corresponding constructs in which the screws could be tightened to the pre-set torque were statistically analysed with respect to relative structural stiffness, maximum axial excursion and width of the osteotomy gap. Loosening of screw No.5 is evident because of deviation of marks on the plate and screw that were in line at the start of testing.

Holding Power of Orthopaedic Screws in Femora of Young Calves. 0000038608 00000 n Conclusion: Fracture compression can be improved either using multiple eccentrically placed screws alternated between the two sides of the plate in LCP and DCP, or by the use of a universal drill guide in DCP. Of these, four pairs were used for basic studies to exactly determine the shape and location of the epiphyseal lines and for the way the femurs were coupled in the testing machine (Figure Treatment and results. (Figure2)2) of the distal fragment in all the constructs. This discrepancy is believed to mainly reflect the relative weakness of calf bones The objective of this study was to compare the Locking Compression Plate (LCP) with the more cost-effective straight-dynamic compression plate (DCP) and wave-DCPs by testing in vitro the effects of plate stiffness on different types of diaphyseal femur fractures (A, B, and C, according to AO classification). Distal femoral fixation: a biomechanical comparison of trigen retrograde intramedullary (i.m.) The AO/ASIF group developed a second generation plating system called the limited contact dynamic compression plate ( LC-DCP) to overcome the shortcomings of a DCP such as a flat undersurface, uneven plate hole distribution (extended middle segment) and a lesser angle of screw insertion of 25 [degrees].

Likewise, the changes in the width of the osteotomy gap were significantly smaller in the three LCP constructs (p < 0.001). In the locking screws, bending occurred more commonly at the transition of the body to the head of the screw. The bone-thread interface was stripped in 21 of 80 cortical screws (26.3%) before a pre-set insertion torque of 3 Nm was achieved. 3 However, the compression hole in the LCP is shorter than in the DCP and their manufacturer's recommended drill guides are different (loading/neutral DCP guide and ⦠0000011120 00000 n Koestlin RG, Nuss K, Elma E.

An insertion torque greater than 3 Nm is necessary to achieve adequate stability and to prevent movement between the components of an osteosynthesis [5]. 0000003306 00000 n The LC-DCP group failed at the 5th test level. Figure 1. It can therefore be concluded that the femoral metaphyses of newborn calves are as weak as osteoporotic bone. A dynamic compression plate (DCP) is a metallic plate used in orthopedics for internal fixation of bone, typically after fractures.As the name implies, it is designed to exert dynamic pressure between the bone fragments to be transfixed. Injury, Int. This versatility allows the surgeon Relative structural stiffness of the three corresponding intact LCP constructs was significantly (p < 0.001) greater than that of the LC-DCP constructs during the first three loading levels and also during the 4th loading level (p < 0.05; Figure [27], which would help to reduce damage to the cis-cortex.
