A biomechanical evaluation of methods of distal humerus fracture fixation using locking compression plates versus conventional reconstruction plates. 5 underwent permanent plastic deformation in seven of 10 constructs in both groups. Fractures of the os femoris are common in newborn calves Transient benign osteopetrosis in a calf persistently infected with bovine virus diarrhoea virus. The screws were not tightened to the pre-set final torque. The linear increase in the LC-DCP constructs possibly is a result from shear forces which occurred after screw loosening and slowed down extraction of the screws. 618 100 [2,16]. Excessive traction on the hind limbs of a calf in posterior presentation may result in femoral fractures if a lever action is applied on the hind limbs [18,20-22]. There was no significant difference in compression between the first two compression screws in DCP and LCP (p=0.64, 0.92).

A mechanical comparison of the locking compression plate (LCP) and the low contact-dynamic compression plate (DCP) in an osteoporotic bone model. 0000077440 00000 n Soft neonatal bone can predispose to loosening of the screws and subsequent instability of the fixation. LCP constructs were significantly more resistant to compression than LC-DCP constructs. The distal position of the plate caused bridging of the growth plate by the two most distal screws. Kim T, Ayturk UM, Haskell A, Miclau T, Puttlitz CM. [8,9]. However, relative structural stiffness was significantly greater and actuator excursion and width of the osteotomy gap significantly smaller in the LCP constructs. [21,26-28]. However, all 20 constructs were tested until failure and then compared with descriptive statistics. Nichols S, Anderson DE, Miesner MD, Newman KD. 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. 0000000016 00000 n [1,2,10,11]. 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 Over-contouring any non-locking plate can cause compression of the transcortex when tightening screws.

Only the DCP, LC-DCP and LCP plates are specifically designed for this: Other than the hybrid LCP, this function is limited to non-locking plates. [34]. Another limiting factor for both constructs was the weak cancellous bone of the distal fracture fragment. The constructs were tested to failure by cyclic compression at a speed of 2 mm/s within six increasing force levels. 0000019422 00000 n Snow M, Thompson G, Turner PG. Madura Orthosurge Pvt. 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). In contrast, bending in cortical screws occurred at the head or at the body. Therefore Titanium plates should be somewhat over-bent to obtain the desired shape. 0000055822 00000 n Only 3 corresponding intact pairs of constructs could be statistically compared for relative structural stiffness, actuator excursion and width of the osteotomy gap. 0000056765 00000 n 0000010758 00000 n The axial compression testing led to craniolateral rotational movement (Figure trailer 0000010484 00000 n List of orthopedic implants; This websites use cookies. To the authors’ knowledge, there are no published guidelines regarding the optimum insertion torque for cortical screws in the calf femur.

Bramlage LR. ​(Table22). In the LC-DCP constructs, all the screws in the two most distal positions (screws No. 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 The recently developed LCP has properties of the DCP and point contact fixator, which provide locking and compression via its combined hole. It can therefore be concluded that the femoral metaphyses of newborn calves are as weak as osteoporotic bone. 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. 0000057232 00000 n Fractures of the femur. ​(Figure2)2) of the distal fragment in all the constructs.

Recently, a novel intramedullary interlocking nail was used for repair of femoral fractures in newborn calves with a good prognosis regardless of the location of the fracture In total, 25 of the 80 cortical (31.3%) and seven of the 40 locking screws (17.5%) were affected (p = 0.108).

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.

Furthermore, plate fixation at this location was thought to be more suitable than fixation using an intramedullary pin, whereas in the diaphysis either technique may be used Stripping of the bone threads of the screw hole before the predetermined torque of 3 Nm had been reached occurred during insertion of 21 of 80 (26.3%) cortical screws; 19 of these were located in the LC-DCP and 2 in the LCP constructs (p < 0.001).

[3] were used for fixation, the outcome was significantly worse for fractures in the distal metaphysis compared with fractures of the diaphysis. The deflection resulted in a rotational movement of the screw heads in the cis-cortex, while the apex of the screws was still fixed in the trans-cortex. A main limiting factor for the stability of both LC-DCP and LCP constructs was the distal fracture fragment. 3.5 mm and 4.5 mm Curved Locking Compression Plate (LCP ®) System The DePuy Synthes Trauma Locking Compression Plate (LCP ® ) System is part of a stainless steel and titanium plate screw system that merges locking screw technology with conventional plating techniques. 0000102261 00000 n 0000057162 00000 n Pairs of intact femurs from 10 calves that had died for reasons unrelated to the study were tested.

Conservative treatment of femoral fractures is rarely successful To determine if locking compression plates (LCP) are mechanically advantageous compared to low-contact dynamic compression plates (DCP) when used as a bridging plate in a synthetic model of osteoporotic bone.

Intramedullary pinning of femoral diaphyseal fractures in neonatal calves: 12 cases (1980–1990). If a “stifle lock” occurs during delivery of a calf in anterior presentation and dorsopubic position, forced extraction can lead to wedging of the femur, which increases axial loading, thus leading to femoral fracture Mediolateral radiographic view of a failed plate osteosynthesis of the left femur of a 3-week-old male Simmental calf 3 weeks after surgery.

For the LCP, two 4.5 mm cortical screws were placed closest to the defect, and 5.0 mm locking screws were used in the four remaining peripheral holes. Dynamic compression is achieved either by attaching a tension device to a plate or by using a special dynamic compression plate.
