epiphyseal fracture example

Percutaneous techniques using large reduction clamps or devices and cannulated screw fixation are acceptable, but the surgeon must be certain of anatomic restoration and no interposed tissue. In commentary on Langenskiold's first 43 clinical procedures excising local bone bridges and interposing autologous fat grafts, the results in general were good to very good; only 7 showed questionable benefit “mainly because the procedure was carried out too close to the end of the growth period” (287). These develop most commonly after certain growth plate fracture-separations (6, 60, 73, 304, 350, 421, 434, 461, 495), in severe cases of Blount's disease (infantile tibia vara), and after infection (409). Interposition of fat, cartilage, silastic, or methyl methacrylate can keep the epiphyseal and metaphyseal circulations separate, thus preventing the formation of further bone bridges and allowing the unaffected growth plate cartilage to continue to grow normally. In this rare injury to the distal tibial growth plate, the distal tibial epiphysis undergoes true rotational displacement with posterior displacement of the fibula but without fracture of the fibula.8,87,108 The fibula in these cases appears to be plastic enough to twist without breaking. MRI is from the coronal (lateral) plane. (Ai) A central transphyseal bone bridge (arrow) is shown at left in a 7-year-old girl who suffered a distal tibial growth plate arrest subsequent to meningococcemia of infancy. Diagnosis of an epiphyseal fracture is not always straightforward. DBM is capable of withstanding shear forces and does not impair elasticity in the implant, and partially mimics the autologous environment in bone, although allogeneic antigens and pathogens may not have been fully removed. It usually occurs at the lower end of the tibia, which is one of the long bones located in the lower leg. The shaft of a bone is referred to as the diaphysis while the rounded portion on each end is called the epiphysis. DBM shares many structural and functional similarities to autologous bone and, as expected, supported osteogene function of MSCs (Mauney et al., 2004). The Salter-Harris type classification of physeal fractures has been used to describe children's long-bone growth plate fractures for more than 40 years, and despite other classifications systems being described,27–29 the Salter-Harris system is considered the standard in the literature.23 This classification system is based on the radiographic appearance of the fracture (Figure 19-3) and indicates the extent of involvement of the joint, the epiphysis, and the physis. Volar fixation with plate and screws can result in prominent hardware along the dorsum of the distal forearm and wrist area. Optimized vascularization is essential, as cell labeling experiments show a considerable loss of OB in the first week following transplantation in porous cancellous bone matrices, presumably due to suboptimal initial vascularization (Kneser et al., 2006). 5-12). In the major long bones, the fracture of the distal radial epiphysis is most common in all series, with injuries of the distal tibial epiphysis and distal humeral epiphysis next in frequency. Four critical factors to successful bone tissue engineering are osteoconduction, osteoproduction, osteoinduction, and mechanical stimulation. The ulna is subluxated and forearm rotation is limited. Example sentences from the Web for epiphysis The radius and ulna are nearly equal in size and each consists of a long shaft terminated at either end by an epiphysis. Osteoproduction is the production of bone material by cells, and osteoinduction is the use of growth factors that draw additional osteogene cells to the site. Disks of cartilage near each end of an immature long bone allow the bone to grow. James R. Kasser, Paul J. Moroz, in The Pediatric and Adolescent Knee, 2006. Persistent pain after distal radius fracture may be related to an associated chondral injury, triangular fibrocartilage (TFC) tear, or scapholunate ligament injury. 26A). Another interpositional material used was cartilage, which in experimental studies had just as effective a result as the fat (357). Epidemiology. Growth plates are the softest and weakest sections of the skeleton — sometimes even weaker than surrounding ligaments and tendons. Some classification systems add a Type VI epiphyseal fracture in which part of the epiphysis, epiphyseal plate, and metaphysis are completely missing. Currently, using orthopedic prosthetics is a severe but highly functional option. 30, 31 For load-bearing long bones such as the femur, mechanical stability of the construct is crucial, whereas for finer tissues such as fingers or craniofacial applications, plasticity takes an increased significance. 15-17). Management needs to be individualized and depends on the location of the bar, the size of the bar, and the amount of remaining growth. In these cases, a salvage procedure, such as a Darrach or Sauvé-Kapandji, is required (Fig. A Salter-Harris fracture is an injury to the growth plate area of a child’s bone. Such a fracture typically requires immobilization and sometimes requires repositioning of the bone pieces if there is significant displacement. The plate is then firmly secured to the radius using bicortical screw fixation (Fig. This is the only mechanism that is considered to result in a displaced growth plate fracture of the distal tibia without any associated fibular fracture. They are called the epiphysis (the tip of the bone) and metaphysis (the “neck” of the bone). 1965. Distraction osteogenesis, a surgical procedure for bone reconstruction and lengthening, was developed in the 1950s by Ilizarov and is still used today. Treatment requires plate and screw removal, which can be difficult with titanium implants. (Aii) A peripheral bone bridge (arrow) of the proximal media tibia following Blount's disease is seen (right). Corrective osteotomy with bone grafting is indicated in patients with pain or limited motion. Immobilization usually is required for 6 to 8 weeks, at which point gradual weight bearing and range of motion may be advanced as tolerated. 26C. Each of these methods has advocates; the interposition of fat is the easiest and most commonly used approach clinically. 26A. Partial destruction of the function of the growth plate is associated with the formation of localized transphyseal bone bridges (287, 313). As the number of surgeries requiring bone grafting continues to rise, the development of functional tissue-engineered bone grafts becomes increasingly significant. 26C. Following interposition of the fat graft the radiolucent area of the fat transplant usually has a rounded or oval shape, whereas following subsequent growth the radiolucent area becomes elongated. Mouse primary myoblasts over-expressing Runx2 via aretroviral system were implanted in conjunction with collagen scaffolds in the hind legs of mice and resulted in trabecular bone growth (Gersbach et al., 2006). Examples of a bone bridge resection procedure are shown in Fig. Fortunately, this injury occurs in children close to skeletal maturity and progressive ulnar-negative variance is not a concern because ulnar-negative variance up to 1 cm is usually asymptomatic.21 However, in the young child the length of the ulna needs to be addressed by distraction osteogenesis. From Project Gutenberg In rachitis epiphyseal swellings are seen at the wrists and ankle-joints, and in superior cases at the ends of the phalanges of the fingers and toes. 66-21A and B). Gene therapy also holds promise for bone tissue engineering. They are classified into 5 different types. If it is determined that significant growth remains and the surgeon opts for surgical treatment, care must be taken to extract any interposed periosteum because it is fairly common in this injury pattern. Initial fittings of casts, splints, strappings, and other materials are included in the global service of fracture care. A rarer fracture in which part of the epiphysis and growth plate are separated from the metaphysis is classified as a Type III epiphyseal fracture. Reduction is achieved with an audible click, probably caused by the fibula snapping back into the metaphyseal portion of the incisura fibularis and having retained its normal relationship and attachments to the displaced tibial epiphysis. (29) studied 18 cases of bone bridge resection in childhood and concluded that there were 9 good results and 9 failures. The fate of the fat implants was studied experimentally by making round cavities in the proximal end of the tibial growth plates in pigs and filling them with autologous fat. Various scaffold strategies have been used for MSC-based bone tissue engineering. Twenty of the 29 bridges were caused by fracture, 3 by tumors, 3 by tibial traction pins, and 1 by infection. (A) Mature transphyseal bone bridges can be seen on plain radiographs. Most TFC and scapholunate ligament tears are partial and can be treated by arthroscopic inspection and débridement. A distal radius corrective osteotomy can be addressed from a dorsal or volar approach. The exact position and extent of bone bridges can be shown by tomography, CT scanning, and magnetic resonance imaging (Fig. 1990 Nov-Dec. 10 (6):713-6. . Angulation less than 20 degrees will remodel over 2 years; greater angulation requires additional growth. It is difficult to detect and often remains undiagnosed until a disturbance in normal growth becomes evident. Failure to recognize a growth plate arrest can quickly lead to deformity (Figs. Bone fractures & growth plate injuries It appeared that the fat was augmented by fat cells in the metaphysis. In addition, the ulna may be addressed by epiphysiodesis and/or shortening (Fig. Other clinical studies have assessed the treatment of partial physeal growth arrest by bridge resection and fat interposition. Porous ceramics, such as those composed of tricalcium phosphate and hydroxyapatite, have been used in conjunction with MSCs to produce bone replacement tissues successfully in patients who failed traditional therapies (Quarto et al., 2001). fracture at one of the ends of a long bone in a growing child involving its growth plate is known Later recognition requires assessment of the articular surfaces of the distal ulna and sigmoid notch. Type II: Fracture through the physis and the metaphysis. 26B). In a series of experiments in his laboratory many types of interpositional materials were used, but fat was both the easiest and the most effective in preventing the reformation of bone bridges and thus maintaining physeal function. The results correlated inversely with bridge size. Direct implantation of MSCs into growth plate defects resulted in a significant reduction of growth arrest in rabbit tibia (Chen et al., 2003). 5-14). An injury that might cause a joint sprain for an adult can cause a growth plate fracture in a child.Growth plate fractures often need immediate treatment because they can affect how the bone will grow. Bright (72) reported briefly on 100 patients followed for more than 2 years with silastic interposition material, with 81% of the patients demonstrating some growth after bridge resection and 70% with good to excellent results. Natural coral has been investigated for decades as a bone graft substitute, and is biocompatible, osteoconductive and biodegradable. The injury is of the supination–plantar flexion variety with a Salter–Harris type I distal tibial fracture and an intact fibula. The spinal vertebrae are examples of what kind of bone? The resultant deformity varies according to the location and extent of the physeal bar. Central bone bridges lead to shortening without angular deformation, whereas peripheral bone bridges lead to angular deformity as well as shortening. Congenital defects of bone, growth plate fractures and defects, fractures resulting in malunion or non-union, the genetic disorder osteogenesis imperfecta (brittle bone disease), and bone loss from tumor resection (primary bone tumors or tumors metastatic to bone) are just a handful of musculoskeletal problems that could be addressed by regenerative medicine. After examination of a patient, a doctor usually orders an X-ray of the affected area. Such fractures are usually the result of trauma such as an accident with heavy machinery, a gun shot wound, and so on. The MSCs demonstrated chemotactic ability by responding to the local fracture environment and locating preferentially to the fracture site, where they also accelerated the healing process (Shen et al., 2002). A wide variety of patients with significant bone defects that necessitated amputation in the past now benefit from various orthopedic strategies. A layer of dense bone remained interposed at the periphery of the fat graft. 66-20A and B). In contrast, small central bars cause tenting of the articular surface and larger bars prevent any longitudinal growth, which results in shortening of the radius relative to the ulna. 15-15). epiphyseal definition: 1. relating to the epiphysis (= the rounded end of a long bone where it joins another bone): 2…. Which bone developed by endochondral ossification? Clearly, there is little need for reduction of mild residual physeal displacement aimed at decreasing the likelihood of growth arrest in a patient with very little remaining growth. A significant percentage of bone fractures occur because of high force impact or stress.. Similar to adults, the volar approach and volar locking systems have gained popularity to avoid prominent hardware. The surgeon must weigh the risk/benefit ratio between intra-articular osteotomy and acceptance of the malunion. These cells act as vehicles producing osteoinductive proteins and have been demonstrated to heal critically sized bone defects (Young et al., 2002). In those studies that accurately document all physeal fractures, it is those of the hand and in particular the phalanges of the fingers that are the most common. Tissue-engineered bone used for clinical applications should meet both biological and mechanical requirements. The possibility of removing focal bone bridges was raised over 100 years ago by Ollier (354). The graft can be harvested from the ulna or iliac crest depending on the size of the defect. Separation of the epiphysis of a long bone, caused by trauma. A second X-ray of a comparable area that is not injured, such as the other elbow for example, may also be ordered for comparison purposes. An epiphyseal plate is located between the epiphysis and the metaphysis at each end of a long bone. Between these two areas lies a flared portion of the bone at each end called the metaphysis. The distal portion of a fixed-angle plate is contoured and applied parallel to the physis and articular surface (Fig. 1990 Nov-Dec. 10 (6):713-6. . Growth plate closure occurs in 4% to 5% of all Salter-Harris distal radius fractures.20,21 All growth plate fractures require a radiograph 3 to 6 months after healing to ensure continued growth. Examples of bone bridges are shown in Fig. This type of fracture is more common in older children. Aufaure et al. Langenskiold concluded that the free fat grafts implanted at the time of resection continued to grow and thus had filled out the elongated cavities. Such fractures typically require surgical treatment and often require later corrective surgery as well. Growth plate closure occurs in approximately 4% to 5% of all Salter-Harris distal radius fractures.21,22 Therefore, all growth plate fractures mandate a follow-up x-ray 3 to 6 months after healing to ensure continued growth. These fractures cross through a portion of the growth plate and break off a piece of the bone end. These are epiphyseal separations and articular fractures. For example, if the injury occurs in your finger, you might not be able to move the finger for a period of time. Twenty of the bridges were peripheral, 6 were central, and 3 were combined. Rare Fracture (<1% of Epiphyseal Fractures) requiring severe mechanism (e.g. Arthroscopic treatment can result in long-term improvement.23,24 In cases of peripheral TFC tears, open or arthroscopic repair is warranted.24. This is the most common type of growth plate fracture. ... acromegaly. Depending on what parts of the bone are broken, an epiphyseal fracture may be classified as one of five or six types of fractures. Fractures of the proximal humeral epiphyseal plate. The presence of an epiphyseal disk indicates that. The focus of treatment should be based on congruity of articular reduction because the complications surrounding these injuries arise from nonanatomic incongruous relationships, leading to early degenerative changes rather than the more popular but erroneous presumption of growth arrest. Percutaneous autologous bone-marrow grafting, the re-introduction of aspirated bone marrow directly to the site of a non-union in the tibia, has been described in human patients with good results (Hernigou et al., 2005). No compromise should be accepted at the articular surface for fear of early degenerative changes. Peripheral bars lead to angular deformity secondary to unequal growth of the physis. Any articular incongruity necessitates open management (Fig. Mini-fluoroscopy is used to avoid the physis. The Salter-Harris classification describes growth plate fractures and has five levels (I–V) that guide acute management as well as overall prognosis. If host MSCs could be augmented or replaced, future OB could then produce osteoid of higher quality. William C. McGarvey, in Baxter's the Foot and Ankle in Sport (Second Edition), 2008. The large majority of procedures involved the distal femur, proximal tibia, and distal tibia. 66-18 and 66-19). For example, even with Salter-Harris type II fractures of the distal femur, one can see shortening and angulation occurring in up to 40% of cases, rates usually seen for type III and IV fractures. They concluded that the former resection cavities were filled primarily by fatty tissue and that the portion of implanted fat had grown in size corresponding with the growth in length of the bones in the affected ends. No special studies are required for this injury because the diagnosis is fairly straightforward. The higher the classification, the more likely joint incongruity or growth disturbance will occur. Autografts contain the patient's own OB and osteocytes, but require a second surgical site for the bone harvesting, most often the iliac crest of the pelvis. Mann DC, Rajmaira S. Distribution of physeal and nonphyseal fractures in 2,650 long-bone fractures in children aged 0-16 years. These injuries are rare in children. The larger the bone bridge, the greater the likelihood of failure. Correction is assessed via mini-fluoroscopy, and adjustments made accordingly. Langenskiold et al. If this alignment is not maintained perfectly during recovery, the outlook for proper bone growth is poor. They were uniformly excellent for bridges less than 25% of the physeal volume, bridges between 25 and 50% yielded good to excellent results in 9 of 12 cases, and results were generally poor in bridges greater than 50% with only 1 of 4 yielding a good result. Compression fractures of the epiphyseal plate are rare and generally involve crushing of the end of the bone and the growth plate. Williamson and Staheli (506) assessed 29 physeal resections, 22 of which were followed for more than 2 years. 5-15). See more. 1. Type IV fractures run through the epiphysis, the epiphyseal plate, and into the metaphysis. They are approximately twice as common in males as in females and approximately three times as common in the upper extremity as in the lower extremity. Medical Definition of Epiphyseal fracture. Examples of child-specific fractures include epiphyseal, or growth-plate fractures, greenstick fractures and bending fractures. Still, if the blood supply is maintained to the separated portion of the epiphysis, chances for normal growth of the bone are still good. We explain the types, treatments, and recovery times for this injury. 29 In most other long-bone epiphyseal fractures seen elsewhere in the body, type II fractures do not have the same extent of growth arrest problems as the knee region. Bright (72) classified partial growth arrest lesions into three types: type I, peripheral lesion; type II, central lesion; and type III, combined central–peripheral lesion. This type of fracture is sometimes referred to as a Salter fracture or a Salter Harris fracture. It is clear from multiple published series that this plantar flexion injury is the least common of the pediatric ankle injury patterns.3,15,135 Displacement is also typically subtle, and the lateral radiograph is the most likely to show mild widening of the tibial physis (Fig. The nose, for example, consists of the nasal bone, the upper lateral cartilage, and the lower lateral cartilage. Tomography has been shown to provide a good percentage estimate of physeal area replaced by the bone bridge, but CT or MR scanning with three-dimensional reconstruction is used currently (96). An epiphyseal plate is located between the epiphysis and the metaphysis at each end of a long bone. Gene therapy with an MSC-based vehicle is also being harnessed for the treatment of a genetic disease. Extensive bridges particularly those located centrally, therefore, had a poor prognosis and all bone bridges due to osteomyelitis were failures. Assuming there is no interruption of the blood supply to the epiphyseal plate, it is likely that the bone will grow normally. Diagnostic Imaging ... Triplane Fracture: Case Example CT Scan Following Attempted Closed Reduction Shows 4mm Intra - articular Diastasis . The mechanism of bone bridge formation was described extensively in Chapter 7. An advanced imaging study, preferably a CT scan, can delineate the magnitude of incongruity and is essential in the decision-making process. (most common type) Type III: Fracture through the physis and epiphysis, passing through the hypertrophic layer as well. These are the most common type of epiphyseal fracture. Growth plate fractures may extend into the metaphysis and/or epiphysis; the different types are classified by the Salter-Harris system. This increases patient morbidity such as post-operative pain and risk of infection. Experimental work in rabbits by others at this time also demonstrated partial bone bridging of the physis (434). Clin Orthop Rel Res. These typically occur in the 12- to 14-year age range as the medial tibial physis begins to close, creating an irregular stress distribution and resistance to forces applied across the ankle (Fig. (288) recalled 3 patients several years after surgery for CT scan assessment of the epiphyseal–metaphyseal region. Depending on what parts of the bone are broken, an epiphyseal fracture may be classified as one of five or six types of fractures. Separations of more than 2 mm in distance along the joint surface, regardless of congruity, should be repaired. The most common growth plate fracture runs through the metaphysis. These areas of growing tissue, known as epiphyseal plates, harden as a child matures to adulthood. Risk of impaired growth increases as fractures progress from type I through type V. An im… Any question of articular irregularity should be settled by obtaining advanced imaging studies, specifically CT scanning, to eliminate the possibility of articular step-off. The Vertebrate Skeleton | Sidney H. Reynolds The epiphysis at the lower end of the femur may be displaced into the ham and press on the popliteal vessels. The child presents with extensor tenosynovitis of the irritated tendons. Radiographs are taken to verify correction of the coronal and sagittal alignment (Fig. J Pediatr Orthop. fall from height) Crushing of physis, most commonly in knee or ankle Early XRay negative (similar to Type I in this regard) Subsequent xrays demonstrate callous formation and delayed bone growth Ollier himself made efforts to remove bone bridges surgically, but recurrence was common due to the failure to use an appropriate interpositional tissue to prevent recurrent bridge formation. The knee region of the growing child, however, may be the one exception to the remarkable prognostic ability of the Salter-Harris system. If there is any question regarding adequacy of reduction, open treatment is required. A growth plate fracture affects the layer of growing tissue near the ends of a child's bones. Torus, greenstick, and bowing fractures are often collectively referred to as “plastic fractures” and are unique to children as a result of the pliability of the pediatric skeleton. Growth plate (physis) injuries in children can result in shortening or angular deformity with the formation of bony bridges across the growth plate between the epiphysis and metaphysis.
