We … Compared with traditional compression plating, locking plates can provide more stability in comminuted or osteoporotic fractures. Injury. d Another plate was added during re-operation to shorten the fracture. 4). 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). J Orthop Trauma. Court-Brown CM, Caesar B. Tomoyuki Noda. The plate-screw assembly distributes stress along the entire length of the plate, making locking plates better suited for osteoporotic bone and multi-segment fractures. A senior medical doctor with > 15 years of experience as an orthopedic surgeon operated on these cases; therefore, a certain surgery quality (reduction of fractures, treatment of soft tissues) was guaranteed. Part of It showed that plate length was 196 mm, fracture distance was 39 mm, plate span ratio was 196/39 = 5.02, bridge span length was 65 mm, medial fracture distance was 5 mm, and empty hole number was 2. These locking bone plates function as a fixed-angle device. Introduction. [14, 15].

Lujan TJ, Henderson CE, Madey SM, Fitzpatrick DC, Marsh JL, Bottlang M. Locked plating of distal femur fractures leads to inconsistent and asymmetric callus formation. Plate screw – can be locking or non-locking head; non-locking produces friction between plate and bone due to compression; locking provides angular stability • Poller/blocking screw – used to redirect an IMN • Lag screw – Inter-fragmentary compression; both fully threaded and partially threaded screws can have a lag effect . Additionally, according to Stoffel et al., the number of empty holes, including the fracture site, should be between one and four in simple fractures, and in comminuted fractures, the screws should be inserted as close to the fracture site as possible [15]. Gwathmey FW Jr, Jones-Quaidoo SM, Kahler D, Hurwitz S, Cui Q. Distal femoral fractures: current concepts. (right forearm) A coronary stent — in this case a drug-eluting stent — is another common item implanted in humans. If a locking compression plate is used, a push- pull device can be inserted in both the proximal and distal fragment to achieve temporary plate stabilization instead of bone holding forceps. Epidemiology of adult fractures: a review. Confirm using image intensification.Drill through the threaded drill guide. Remove the drill guide and measure the appropriate screw length with a depth gauge.Insert the locking screw without completely tightening it. The authors declare that they have no competing interests. Non-union was defined as a state in which bone union was not achieved within 4 months after the initial surgery. Google Scholar. When an intermediate bone fragment exceeding 20 mm was included in the measurement range, the distance between the both ends and the main bone fragment was measured. Iowa Orthop J. For comminuted fractures, the guidelines recommend that the plate length should be at least 2–3 times longer than the fracture length and ≥ 3 empty holes should be left in the surrounding fracture site. Extraarticular fractures of the base of the thumb metacarpal are often … Healing results of periprosthetic distal femur fractures treated with far cortical locking technology: a preliminary retrospective study. 2014 Nov;45(11):1665–73. Locking Compression Plate (LCP) Implants are intended for temporary fixation, correction or stabilization of bones in various anatomical regions. suggested that a locking compression plate should be used as a bridging plate in order to achieve relative stability. Locking plates for distal femur fractures: is there a problem with fracture healing? Orthopaedic Locking Compression Plates are fracture fixation devices that allow fitment of normal conventional bone screws as well as Locking head screws.

In these circumstances, take the opportunity to remove the implants. Working length and proximal screw constructs in plate osteosynthesis of distal femur fractures. Limited contact dynamic compression plates were designed with recesses or undercuts in the plate to reduce contact between the plate and the bone, therefore reducing the risk of plate-associated osteoporosis. Be careful to bend in between the holes by positioning the pliers over the plate holes. Note the visible break in the ulna. Ries Z, Hansen K, Bottlang M, Madey S, Fitzpatrick D, Marsh JL. recommended opening 1–2 holes close to the fracture sites in simple fractures and inserting the screws as close as possible to the fracture sites in comminuted fractures [13].

Smith WR, Ziran BH, Anglen JO, Stahel PF. locking compression plate for distal femur (DePuy Synthes Co., Ltd, New Brunswick, CA, USA). Callus formation was good, but resulted in non-union. Put the plate on the dorsal aspect of the proximal fragment, with a threaded drill guide in one of the outer holes. Non-union rate was significantly higher in comminuted fractures with bone medial fracture distance exceeding 5 mm. 2011;26(4):405–9. 2010 Mar;24(3):156–62. 4.6 out of 5 stars 428. Non-union was founded in simple fractures with bone medial fracture distance exceeding 2 mm, but not significant (p = 0.06). The overall complication and fixation failure rate were comparable to those reported in previous studies in which various locking plate systems were used. Her injury was a simple transverse fracture that resulted in non-union. The Synthes Locking Compression Plate (LCP) is part of a stainless steel and titanium plate and screw system that merges locking screw technology with conventional plating techniques. Conversely, in cases with comminuted fractures, there were five non-union cases with more two empty holes (Table 4). In distal femoral fractures, non-union sometimes may occur, despite improvements in implant and reduction techniques. The alignment was reduced and LCP-DF was used as a bridging plate.

On the other hand, the mean bridge span length of comminuted fractures in the bone union and non-union groups was 92.5 mm (range, 45–190 mm) and 81.2 mm (range, 40–110 mm), respectively (Table 4). J Orthop Surg Res 14, 384 (2019). Santolini E, Goumenos SD, Giannoudi M, Sanguineti F, Stella M, Giannoudis PV. Regarding plate fixation, basic fixation is generally recommended to achieve absolute stability using lag screws in simple fractures; however, lag screw fixation cannot be performed in transverse fractures [7]. Surgical treatment can either be retrograde intramedullary nail fixation or be plate fixation, with plate fixation having a wide indication for various fractures types [5, 6]. 2). 4.6 out of 5 stars 113.

We analyzed several independent variables to determine how they impacted fracture healing; however, it is possible that other variables that were not considered may have contributed to the outcomes. Compared with the proximal section of the femur or femoral trunk, poor blood supply in the distal femur has also been reported to contribute to a higher risk of non-union [25]. Renato Fricker, Matej Kastelec, Fiesky Nuñez, Terry Axelrod. 2001 Dec;32(Suppl 3):SC55–63. 2005 Nov;36(Suppl 4):S30–7. Working length of a plate was defined as the distance between the first screws on either side of the fracture [13].  Fracture fixation devices with threaded screwholes, which allow screws to thread to the plateand function as fixed angle device. Any plate that allows the insertion of fixed angle orangular stable screws or pegs can be used as alocking plate.

Although screw insertions near the fracture site increases fracture stability, in some cases, this may result in a lack of proper fracture micro-motion, leading to poor callus formation [17]. Locking screws provide reported no plate length differences between non-union and union groups, which was similar to our results [20]. Article  2004 Feb;75(1):56–60. Conversely, fracture instability was significantly higher with > 80 mm of bridge span length, which resulted in poor callus formation [21]. PubMed  1994 Sep;15(9):483–9. Google Scholar. 2017;48(11):2597–601. The Locking Compression Plate System has many similarities to existing plate fixation methods, but with a few important improvements. Regarding the number of empty holes, Stoffel et al. Further study in large number of patients is required to comment regarding disadvantages and complications. In order to prevent the screw from penetrating the joint, a slight bend is necessary. The Mann-Whitney U test was performed for statistical comparisons of the average number of empty holes and the average bridge span length. For distal fixation, at least 3 metaphyseal locking screws were used. In cases with simple fractures, one non-union case had one empty hole and one non-union case had four empty holes, whereas in cases with comminuted fractures, five non-union cases had two more empty holes. Always use a threaded drill guide when preparing for locking screws. Clin Biomech (Bristol, Avon). 2006 Apr;88(4):846–53. Megas et al. 2010 Oct;18(10):597–607. This study included 71 distal femoral fractures in 70 patients (23 males, 47 females; mean age, 68.0 years [range, 16–91 years]) who were treated using the locking compression plate for distal femur (DePuy Synthes Co., Ltd, New Brunswick, CA, USA) at a university hospital and related facilities between April 2005 and December 2015. Thus, the purpose of this study was to examine the appropriate screw position in relative fixation. distally the plate was not extended beyond the joint line.

For this procedure the following approaches may be used: Angularly stable plate fixation in the proximal fragment allows for reduction using the plate as a lever (as described below). b Conclusive rules of comminuted fracture for 33A3, 33C2, and 33C3. All the cases in the non-union group fit the plate length of > 2–3 times longer than the overall fracture length (Table 4). Plate span ratio was measured with reference to the length of the plate relative to the length of the fracture line, as proposed by Gautier et al. Rekha YB, Reddy NB. 2006 Aug;37(8):691–7. Bone union was defined as three out of four instances of cortical bridging on AP and lateral radiographs [12]. Preliminary stabilization can be achieved with an obliquely inserted K-wire.If anatomical reduction is demonstrated using image intensification, a 2 mm LCP T-plate is fixed to the dorsal aspect of the first metacarpal using standard locking techniques. 3). 2003 Nov;34(Suppl 2):B63–76. Additionally, Henderson et al. Google Scholar. Tables 2, 3, and 4 summarize the univariate analysis. In this study, non-union was diagnosed in 7 of 71 cases. In compliant patients with stable fixation, the splint can be removed under the supervision of a physical therapist, and early active motion exercises started after a few days.

However, the non-union rate of distal femoral fractures lies between 0 and 34%, indicating considerable variation [3, 4]. Direct plate-to- bone compression is not required, better preserving the blood supply to the bone. Guidelines for defining the terms “plate span ratio,” “empty hole,” and “medial fracture distance” are provided in Fig. Injury. 2006 May;20(5):366–71.

Although adopting the anatomical locking plates procedure revealed positive outcomes, the method is still debatable.Several studies describe a variety of surgical technique and implants to treat this complex fracture. In these circumstances, take the opportunity to remove the implants. PubMed  MK, TN, HN, TM, YY, YM, TU, SY, KD, KS, YS, and TOz selected the appropriate patients and included them in this study. Ricci WM, Streubel PN, Morshed S, Collinge CA, Nork SE, Gardner MJ. Even with relative fixation, the more the empty hole, the higher the risk of a non-union, because bone union was achieved during salvage surgery in non-union cases through plate replacement with a long plate or inserting a screw near the fracture site. Based on our findings, we concluded that bone fragment distance between fracture fragments is more important than bridge span length of the fracture site and the number of empty holes. Distal femoral fractures comprise only 0.4% of all fractures and 4–6% of femoral fractures [1, 2]. A locking screw, using a threaded drill guide when drilling, may be inserted in osteoporotic bone, or when otherwise indicated.The second distal screw is inserted using the same technique. Our study also showed no significant differences between groups (Tables 2, 3, and 4). Schütz M, Müller M, Regazzoni P, Höntzsch D, Krettek C, Van der Werken C, Haas N.

(Redirected from Locking Compression Plate) Orthopedic implants to repair fractures to the radius and ulna. For proximal fixation, 2, 3, and 4 locking screws were used. Fourteen of all comminuted fracture cases and bone union were treated through shortening the fracture site as Rekha reported [16], and non-union was not observed in these cases. Correspondence to The LCP (Locking Compression Plate), the product of these combinations, is in line with the latest plating techniques, the aim of which is to achieve the smallest possible surgical incisions and to preserve the blood supply to the bone and the adjacent soft tissues. Lee CH, Shih KS, Hsu CC, Cho T. Simulation-based particle swarm optimization and mechanical validation of screw position and number for the fixation stability of a femoral locking compression plate. This study received Institutional Review Board approval, and patients provided oral and written informed consents. There were 26 simple fractures and 45 comminuted fractures based on plain antero-posterior (AP) and lateral X-ray images (Table 2). With respect to plate span ratio, 3 of 24 (12.5%) cases with simple fractures in the bone union group fit the plate length that was > 8–10 times longer than the overall fracture length, whereas 21 of 24 (87.5%) cases did not. Immediately postoperatively, a temporary plaster splint is applied which immobilizes the first MCP joint as well as the wrist. The principle of the locking compression plate (LCP) is represented by the combination of two completely different anchorage technologies and two opposed principles of osteosynthesis in one implant it combines the principles of con- ventional plate osteosynthesis for direct anatomical reduction with those of bridging plate osteosynthesis. J Orthop Trauma. Age, open fracture, MIPO, diabetes, steroid use, infection, AO classification, plate span ratio, and bridge span length were of no predictive value. Kolmert L, Wulff K. Epidemiology and treatment of distal femoral fractures in adults. Bone union was observed in all cases with simple or comminuted fractures with respective medial fracture distances of ≤ 2 mm or ≤ 5 mm. If the flexion deformity exceeds 30 degrees, thumb function may be impaired due to muscle imbalance. Hoffmeier KL, Hofmann GO, Mückley T. Choosing a proper working length can improve the lifespan of locked plates. Elkins J, Marsh JL, Lujan T, Peindl R, Kellam J, Anderson DD, Lack W. Motion predicts clinical callus formation: construct-specific finite element analysis of supracondylar femoral fractures. 2.0 mm and 2.4 mm LCP were used to manage appendicular fractures in cats and small dogs. Open fractures were observed in 19 of 71 (26.8%) cases (Table 1). No statistically significant difference in the working lengths of the fracture site was observed between simple fractures and comminuted fractures in both groups (Tables 3 and 4). A compression plate anastomosis apparatus as recited in claim 1, wherein the locking means comprises means for guiding the movement of one compression plate relative to the other, wherein the guiding means extend from one of the compression plates to enable one compression plate to be moved in a fixed parallel orientation relative to the other compression plate, wherein the guiding … Of the comminuted fractures, 18 open fractures were observed; four cases resulted in non-union, which was not a significantly larger proportion than that in the bone union group (Table 4). Locking plates allow screws to be threaded into the plate, creating a fixed-angle device, without the need for friction between the plate and bone. reported that fracture site instability prevents bone callus formation, even with good blood supply [19]. We believe that by decreasing the number of empty holes around the fracture site (i.e., inserting the screw near the fracture site), fracture site stability increased. 1712-035). 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. The details of the surgical approach, the type of plate , and the number and configuration of screws were decided by the surgeon. The requirement for informed consent was waived due to this study’s retrospective design. J Orthop Trauma. 2013 May;99(3):353–60. Femoral and tibial blood supply: a trigger for non-union? The following measurements were evaluated and analyzed: (1) bone union rate, (2) bridge span length (distance between screws across the fracture), (3) plate span ratio (plate length/bone fracture length), (4) number of empty holes (number of screw holes not inserted around the fracture), and (5) medial fracture distance (bone fracture distance on the medial side of the distal femur). We concluded that bone fragment distance between fracture fragments is more important than bridge span length of the fracture site and the number of empty holes. Based on our findings, we concluded that bone fragment distance between fracture fragments is more important than bridge span length of the fracture site and the number of empty holes. 2005 Mar;125(2):102–8. Privacy Cite this article. This screw would normally be a standard screw, as it engages in thick cortical bone. Alternatively, insert the threaded bolt into the plate holes to bend the plate.The bend should never go through a hole as this may damage the locking mechanism. Case 2 was distal femur fracture with Gustilo IIIA in a 73-year-old man; he was run over by a shovel car. [14] and Stoffel et al. reported no significant differences in bridge span lengths of 64.4 and 69.8 mm in two respective cases of non-union and union [20]. d Screws were inserted near the fracture during re-operation. The Synthes 4.5 mm Locking Compression Plate (LCP) System is indicated for fixation of various long bones, such as the humerus, femur and tibia and for use in fixation of peri-prosthetic fractures, osteopenic bone and fixation of non-unions or malunions in adult patients. e Radiograph 1 year after re-operation, a Radiograph with Gustilo type-IIIA in an 80-year-old woman.
