The Synthes Locking Compression Plates—Narrow and Broad, are intended for fixation of various long bones, such as the humerus, femur and tibia. Correspondence to J Orthop Trauma. Injury. Put the plate on the dorsal aspect of the proximal fragment, with a threaded drill guide in one of the outer holes. 2003 Nov;34(Suppl 2):B11–9. The overall complication and fixation failure rate were comparable to those reported in previous studies in which various locking plate systems were used. The bone fracture distance on the medial side of the distal femur was related to bone union rather than screw position. Direct plate-to- bone compression is not required, better preserving the blood supply to the bone. Non-union was diagnosed 2 of 26 (7.7%) cases with a simple fracture and 5 of 45 (11.1%) cases with a comminuted fracture (Table 2). Injury. All surgery was performed by surgeons with more than 15 years of orthopedic experience at university hospital and related facilities. 2010 Feb;26(1):10–6. With this temporary fixation in place, the plate position and anatomical reduction is checked thoroughly and adjusted, if required. Ricci WM, Streubel PN, Morshed S, Collinge CA, Nork SE, Gardner MJ. Therefore, in this study, we examined the correlation between bone union and screw position, as the X-ray parameter. J Orthop Trauma. Femoral and tibial blood supply: a trigger for non-union? 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. This screw would normally be a standard screw, as it engages in thick cortical bone. Mark the plane of the first carpo-metacarpal joint with a thin K-wire or a hypodermic needle. Several example cases are shown in Figs. Google Scholar. c Radiograph and CT showed callus formation 2 months postoperatively; left knee range of motion was 0–140°. J Orthop Surg Res 14, 384 (2019). Working length of a plate was defined as the distance between the first screws on either side of the fracture [13]. Ehlinger M, Ducrot G, Adam P, Bonnomet F. Distal femur fractures. The Locking Compression Plate System has many similarities to existing plate fixation methods, but with a few important improvements. Additionally, there were 13 comminuted fractures with a medial fracture distance of ≥ 2 mm, and the non-union rate was 30.7% (4 of the 13 cases). PubMed 2013;80(3):185–91. 2013 May;99(3):353–60. Kayali C, Agus H, Turgut A. Check the reduction of the dorsal fracture line.Confirm using image intensification. (right forearm) A coronary stent — in this case a drug-eluting stent — is another common item implanted in humans. Patient demographics (age), comorbidities (smoking, diabetes, chronic steroid use, dialysis), and injury characteristics (AO type, open fracture, infection) were obtained for all participants. reported no plate length differences between non-union and union groups, which was similar to our results [20]. J Am Acad Orthop Surg. 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.

Use of the less invasive stabilization system (LISS) in patients with distal femoral (AO33) fractures: a prospective multicenter study. 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). 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. distally the plate was not extended beyond the joint line. e Radiograph 1 year after re-operation, a Radiograph with Gustilo type-IIIA in a 73-year-old man. Smoking and medial fracture distance are prognostic risk factors of nonunion in distal femoral fractures treated with LCP as bridging plate. 2010 Dec;92(Suppl 2):12–22. The mechanism locking the screw in the plate also comes in two types: in the first the screw head is locked in its chamber by a threaded locknut. It is a single-beam construct where the locking compression plate for distal femur (DePuy Synthes Co., Ltd, New Brunswick, CA, USA). Bottland et al. 14-19 Even though the anatomical locking plate is an efficient implant for proximal humerus fracture, there are report of surgical complications. Injury. Of 26 simple fractures, there were 7 cases with a medial fracture distance of ≥ 2 mm, and the non-union rate was 28.5% (2 of the 7 cases) (Table 3). 1712-035). Orthopaedic Locking Compression Plates are fracture fixation devices that allow fitment of normal conventional bone screws as well as Locking head screws. 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]. The alignment was reduced and LCP-DF was used as a bridging plate. For distal fixation, at least 3 metaphyseal locking screws were used. The “far cortical locking technology” was demonstrated to increase fracture stability and flexibility; however, long-term results have not yet been obtained [18]. Recognizing The Potential Benefits Of Locking Compression Plates $25.99 $ 25. 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. 2016 Feb 17;98(4):276–84. PubMed Google Scholar. PubMed Performing shortening and fixation of up to 5–10 mm was effective for achieving bone union in several comminuted fracture cases (Fig. 2004 Feb;75(1):56–60. The mean bridge span length of simple fractures in the bone union and non-union groups was 72.2 mm (range, 25–110 mm) and 72.5 mm (range, 45–100 mm), respectively (Table 3). The guidelines reported by Gautier et al. Risk factors for non-union and delayed bone union in distal femoral fractures include the presence of open fracture(s), medial bone defects, and comminuted fracture(s) [3, 24]. Henderson et al. PubMed 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. Regarding the number of empty holes, Stoffel et al. 3). J Bone Joint Surg Am. Effects of construct stiffness on healing of fractures stabilized with locking plates. 2005 Mar;125(2):102–8. a Radiograph in a 74-year-old woman with total knee arthroplasty. Additionally, of the 45 cases with comminuted fractures, 13 cases had a medial fracture distance of ≥ 2 mm, and non-union was observed in 4 of these 13 (30.7%) cases. observed a 19% bone union failure rate in a cohort of 70 patients and reported that there were significantly more empty holes proximal to the fracture site in the patients with non-union compared to those with successful bone union [23]. PubMed Central volume 14, Article number: 384 (2019) 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]. During surgery, it is sometimes difficult to properly determine screw position. Tomoyuki Noda. 1982 Dec;53(6):957–62. c Radiograph and CT showed no callus at 6 months postoperatively. Acta Orthop Scand. b Conclusive rules of comminuted fracture for 33A3, 33C2, and 33C3. Healing results of periprosthetic distal femur fractures treated with far cortical locking technology: a preliminary retrospective study. Our study also showed no significant differences between groups (Tables 2, 3, and 4). 2.0 mm and 2.4 mm LCP were used to manage appendicular fractures in cats and small dogs. Acta Chir Orthop Traumatol Cech. 4.6 out of 5 stars 113. Heckman JD, Ryaby JP, McCabe J, Frey JJ, Kilcoyne RF. 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). After removal of plates, fractures may occur through the screw holes. Foot Ankle Int. 2). Thus, the purpose of this study was to examine the appropriate screw position in relative fixation. Thus, Locking Compression Plate is an important armamentarium in treatment of the Distal femur fractures especially when fracture is closed, severely comminuted and in situations of osteoporosis. suggested that a locking compression plate should be used as a bridging plate in order to achieve relative stability. Risk factors for failure of locked plate fixation of distal femur fractures: an analysis of 335 cases. Univariate analysis was performed on them. Confirm using image intensification.Drill through the threaded drill guide. The final manuscript was approved by all authors. J Orthop Trauma. There are few reports on the relationship between the screw position and bone union when fixing by the bridging plate (relative stability) method. Her injury was a simple transverse fracture that resulted in non-union. 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. (Redirected from Locking Compression Plate) Orthopedic implants to repair fractures to the radius and ulna. 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. Injury. 2.0 mm and 2.4 mm LCP were used to manage appendicular fractures in cats and small dogs. 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. 4.6 out of 5 stars 428. All of the authors critically revised the manuscript. Case 2 was distal femur fracture with Gustilo IIIA in a 73-year-old man; he was run over by a shovel car. 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). The pull of the thenar muscles results in palmar flexion of the distal fragment. Furthermore, 36 of 40 (90%) cases with comminuted fractures in the bone union group fit the plate length that was > 2–3 times longer than the overall fracture length, whereas 4 of 40 (10%) cases did not. Internal fixation allows for anatomical reduction. b Postoperative radiograph. 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]. Hoffmeier KL, Hofmann GO, Mückley T. Choosing a proper working length can improve the lifespan of locked plates. 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. 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. Insert a screw through the most distal plate hole. 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 … Ries Z, Hansen K, Bottlang M, Madey S, Fitzpatrick D, Marsh JL. Additionally, none of the cases in the non-union group fit the plate length of > 8–10 times longer than the overall fracture length (Table 3). Clin Biomech (Bristol, Avon). d Another plate was added during re-operation to shorten the fracture. Insert a second screw using the same technique. The present study was approved by Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital (Ethics Committee No. Compared with traditional compression plating, locking plates can provide more stability in comminuted or osteoporotic fractures. Additionally, Henderson et al. 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. Gwathmey FW Jr, Jones-Quaidoo SM, Kahler D, Hurwitz S, Cui Q. Distal femoral fractures: current concepts. Our new stainless steel plate, called the minimum contact locking compression plate (MC-LCP), has protrusions on the plate undersurface, two dynamic compression screw holes and six locking screw holes. 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). Zlowodzki M, Bhandari M, Marek DJ, Cole PA, Kregor PJ. MK drafted the manuscript. In most of our cases, non-union likely resulted from fracture site instability after reduction internal fixation. 2007 Oct;89(10):2298–307. 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]. 2001 Dec;32(Suppl 3):SC55–63. Immediately postoperatively, a temporary plaster splint is applied which immobilizes the first MCP joint as well as the wrist. By using this website, you agree to our 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. 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. Locking compression plate (LCP) dynamic compression unit conical and threaded unit 4. Renato Fricker, Matej Kastelec, Fiesky Nuñez, Terry Axelrod. The mean follow-up period was 20.8 months (range, 5–33 months) (Table 1). Locking plates for distal femur fractures: is there a problem with fracture healing? 2, 3, and 4. statement and Get it as soon as Tue, Nov 24. reported that increasing fracture site flexibility promotes initial bone formation, but had no correlation with bridge span length [23]. Locking Compression Plate (LCP) Implants are intended for temporary fixation, correction or stabilization of bones in various anatomical regions. Powerbuilt Steering Wheel Lock Plate Remover - 648466. 2011;26(4):405–9. In locking plate fixation, the locking plate is applied through an incision over the volar (palm) aspect of the wrist. Align the plate along the axis of the shaft. Age, open fracture, MIPO, diabetes, steroid use, infection, AO classification, plate span ratio, and bridge span length were of no predictive value. c Radiograph and CT showed non-union 8 months postoperatively. 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. Orthop Traumatol Surg Res. Cases in which the proximal and distal bone fragments were fixed using a lag screw and those in which the medial plate was used during the initial surgery were excluded. Journal of Orthopaedic Surgery and Research 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. 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. However, the non-union rate of distal femoral fractures lies between 0 and 34%, indicating considerable variation [3, 4]. 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]. 2010 Mar;24(3):156–62. J Orthop Trauma. Non-union was defined as a state in which bone union was not achieved within 4 months after the initial surgery. J Bone Joint Surg Am. 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. Callus formation was good, but resulted in non-union. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. Epidemiology of adult fractures: a review. Remove the drill guide and measure the appropriate screw length with a depth gauge.Insert the locking screw without completely tightening it. Google Scholar. 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. Article Extraarticular fractures of the base of the thumb metacarpal are often … Arbeitsgemeinschaft für Osteosynthesefragen/Orthopedic Trauma Association, Locking compression plate for distal femur. In Henderson et al.’s study involving 70 patients, the average number of empty holes proximal to the fracture site was 0.3 in the non-union group and 1.1 in the bone union group [20]. J Bone Joint Surg Am. Read about company. Be careful not to overbend, as there is a comminuted zone at the opposite cortex, which can not withstand compression. Introduction. The implants may need to be removed in cases of soft-tissue irritation.In case of joint stiffness, or tendon adhesions’ restricting finger movement, tenolysis or arthrolysis become necessary. In this study, non-union was diagnosed in 7 of 71 cases. 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). Henderson CE, Kuhl LL, Fitzpatrick DC, Marsh JL. The requirement for informed consent was waived due to this study’s retrospective design. Arch Orthop Trauma Surg. J Appl Biomech. Bottlang M, Doornink J, Lujan TJ, Fitzpatrick DC, Marsh JL, Augat P, von Rechenberg B, Lesser M, Madey SM. When plates are used, atrophy of the bone beneath the plate may predispose the bone to fracture. Kolmert L, Wulff K. Epidemiology and treatment of distal femoral fractures in adults. Extraarticular fractures of the base of the thumb metacarpal are often displaced, with a flexion deformity and may show palmar comminution (Winterstein fracture). 2004 Sep;18(8):503–8. 2011 Feb;25(Suppl 1):S8–14. 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]. Med Eng Phys. Kiyono, M., Noda, T., Nagano, H. et al. MK, TN, HN, and TM performed the statistical analysis and interpreted the results. One female patient had bilateral femoral fractures. Santolini E, Goumenos SD, Giannoudi M, Sanguineti F, Stella M, Giannoudis PV. The details of the surgical approach, the type of plate , and the number and configuration of screws were decided by the surgeon. Megas et al. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. In the second, the screw head is itself threaded and screws into the plate or into an adapted lip. Terms and Conditions, A biomechanical study. The number of empty holes near the fracture site and the rate of bone healing were not clearly related. In distal femoral fractures, non-union sometimes may occur, despite improvements in implant and reduction techniques. b Postoperative radiograph. J Bone Joint Surg Am. The combi-hole is a combination of a DCP hole and a locking hole allowing the surgeon to place either a Reducing comminuted bone fragments is difficult when the inner portion of the fracture site also exhibits comminuted fracture. 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. All the cases in the non-union group fit the plate length of > 2–3 times longer than the overall fracture length (Table 4). a Conclusive rules of simple fracture for 33A2 and 33C1. Results with a p value of < 0.05 were considered significant. In these circumstances, take the opportunity to remove the implants. Int J Res Orthop. Conversely, fracture instability was significantly higher with > 80 mm of bridge span length, which resulted in poor callus formation [21]. 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. Pressing the plate down to the diaphyseal fragment with a periosteal elevator will automatically tilt the articular fragment into its correct position. 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. Smith WR, Ziran BH, Anglen JO, Stahel PF. There were 26 simple fractures and 45 comminuted fractures based on plain antero-posterior (AP) and lateral X-ray images (Table 2). 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 ABN Automotive Car Steering Wheel Puller Compressor Remover Set – Vehicle Steering Wheel Lock Plate Removal Tool Kit.
