Epidemiology of fractures in England and Wales. identify joint involvement and articular step-off (>25%, >2mm requires ORIF) . Damage to this nerve may result in deficits in those movements. Full healing usually is accomplished by 68 weeks. rotation about a planted foot and ankle, accounts for 35-40% of overall tibial growth and 15-20% of overall lower extremity growth, growth continues until 14 years in girls and 16 years in boys, closure occurs during an 18 month transitional period, pattern of closure occurs in a predictable pattern: central > anteromedial > posteromedial > lateral, closure occurs 12-24 months after closure of distal tibial physis, Ligaments (origins are distal to the physes), primary restraint to lateral displacement of talus, anterior inferior tibiofibular ligament (AITFL), extends from anterior aspect of lateral distal tibial epiphysis (Chaput tubercle) to the anterior aspect of distal fibula (Wagstaffe tubercle), plays an important role in transitional fractures (Tillaux, Triplane), posterior inferior tibiofibular ligament (PITFL), extends from posterior aspect of lateral distal tibial epiphysis (Volkmanns tubercle) to posterior aspect of distal fibula, extends from posterior distal fibula across posterior aspect of distal tibial articular surface, functions as posterior labrum of the ankle, Fracture extends through the physis and exits through the metaphysis, forming a Thurston-Holland fragment, Fracture extends through the physis and exits through the epiphysis, Seen with medial malleolus fractures and Tillaux fractures, Fracture involves the physis, metaphysis and epiphysis, Can occur with lateral malleolus fractures, usually SH I or II, Seen with medial malleolus shearing injuries and triplane fractures, Can be difficult to identify on initial presentation (diagnosis is usually made when growth arrest is seen on follow-up radiographs), Results from open injury (i.e. seen with SER-type fracture patterns, AITFL avulsion of anterior tibial margin (tibial The deep peroneal nerve innervates the musculature of the anterior compartment and is responsible for the dorsiflexion of the foot and toes. It may include some of the following approaches, used either alone or in combination: An open fracture occurs when the bone or parts of the bone break through the skin. Sometimes they may also involve the fracture of the growth plate (physis) located at each end of the tibia. B2 w/ medial lesion (malleolus or ligament) B3 w/ a medial lesion and fracture of posterolateral tibia. - frx above the syndesmotic result from external rotation or abduction forces that also disrupt. This article focuses on the shaft of the fibula, which can be located between the neck of the fibula, the narrowed portion just distal to the fibular head, and the lateral malleolus, which in concert with the posterior and medial malleoli, form the ankle joint. There are three types of tibial shaft fractures: These fractures occur at the ankle end of the tibia. This procedure involves placing a piece of foam in the wound and using a device to apply negative pressure to draw the edges of a wound together. At Another Johns Hopkins Member Hospital: Tibia fractures are the most common lower extremity fractures in children. Fibular avulsion fractures most commonly occur from an inversion of the ankle that causes the ankle ligaments to pull a small piece of bone off of the end of the fibula. High-energy fractures, such as those caused by serious car accidents or major falls, are more common in older children. Fractures may involve the knee, tibiofibular syndesmosis, tibia, or ankle joint. These fractures occur in the knee end of the tibia and are also called tibial plateau fractures. proximal 1/3 tibia fractures account for 5-10% of tibial shaft fractures. Surgery may also be needed depending on the wound size, amount of tissue damage and any vascular (circulation) problems. The injury produces pain, tenderness, and swelling of the ankle making weight-bearing difficult or impossible. Rarely, a fracture of the fibula may be. C2: diaphyseal fracture of the fibula, complex. Tibia and fibula fracturesare characterized as either low-energy or high-energy. (0/3), Level 1 Nonsurgical Treatment. At its most proximal part, it is at the knee just posterior to the proximal tibia, running distally on the lateral side of the leg where it becomes the lateral malleolus at the level of the ankle. - C2 diaphyseal fracture of the fibula, complex. Wang Q, Whittle M, Cunningham J, et al. Are you sure you want to trigger topic in your Anconeus AI algorithm? Posterior Malleolus and Fibula Fracture ORIF - Orthobullets There is very limited mobility between this syndesmosis. Fractures of the tibia and fibula are typically diagnosed through physical examination andX-rays of the lower extremities. Q: Do syndesmotic screws require removal? Diagnosis can be suspected with a knee effusion and a positive dial test but MRI studies are required for confirmation. Medial malleolus transverse fracture or disruption of deltoid ligament . Additionally, lateral collateral ligament of the knee originates from the lateral epicondlye of the femur to insert on the superior portion of the fibular head and is the . Lateral short oblique fibula fracture (anteroinferior to posterosuperior), 3. Tibia and fibula fractures in soccer players. Located posterolaterally to the tibia, it is much smaller and thinner. Medial malleolus transverse fracture or disruption of deltoid ligament, 3. Patients with isolated fibular shaft fractures are instructed to bear partial weight. Are you sure you want to trigger topic in your Anconeus AI algorithm? At its most proximal part, it is at the knee just posterior to the proximal tibia, running distally on the lateral side of the leg where it . Treatment is generally operative with intramedullary nailing. C3: proximal fracture of the fibula. Patients are counseled that, although fibula fractures. Transverse comminuted fracture of the fibula above the level of the syndesmosis. ORIF of fibula fractures; resection of fibula; excision of fibula bone lesions; Internervous plane: Between . The injury is common in athlete who is engaged in collision or contact sport . Patients require pain medicine as appropriate. Vaccines & Boosters | Testing | Visitor Guidelines | Coronavirus. Weber C fractures can be further subclassified as 6. highest incidence in male is between 15-24 years of age, highest incidence in females is 75-84 years of age, modified hinge joint consisting of tibia, fibula, and talus, tibial plafond and talus are broader anteriorly and wider laterally, extends from medial malleolus to broad insertion onto navicular, sutentaculum tali, and talus, primary restraint to anterior displacement, IR, and inversion of talus, strongest ligament of lateral complex and least likely to be disrupted, anterior inferior tibiofibular ligament (AITFL), originates from anterolateral tubercle of distal tibia (Chaput), inserts anteriorly onto lateral malleolus (Wagstaffe), posterior inferior tibiofibular ligament (PITFL), broad origin from posterior tibia (Volkmann's fragment), inserts onto posterior aspect of lateral malleolus, distal continuation of intraosseous membrane, peroneus longus and brevis pass along posterior groove of lateral malleolus, at risk with posterolateral fibular plating, located posterior and inferior at the level of the medial malleolus, at risk with posterior placement of medial malleolus screws, course over anterior ankle between EDL and EHL, course posterior to medial malleolus between FDL and FHL, crosses anteriorly over fibula about distal 1/3, at risk with posterolateral and direct lateral approach to fibula proximally and with anterior/anterolateral approaches, at risk with posterolateral and direct lateral approach to fibula, primary restraint to anterolateral talar displacement, acts as buttress to prevent lateral displacement of talus, dorsiflexion results in fibula ER and lateral translation, accommodating anteriorly wider talus, plantarflexion results in narrower, posterior aspect of the talus leading to IR of talus, based on combination of foot position and direction of force applied at the time of injury, has been shown to predict the observed (via MRI) ligamentous injury in less than 50% of operatively treated fractures, 1. Pathophysiology. 2023 Lineage Medical, Inc. All rights reserved. performed with the hip flexed 45, knee flexed 80, and foot is ER 15. Wounds may be treated with vacuum-assisted closure. Incision. In rare cases, external fixation or ORIF is more appropriate depending on the location and orientation of the fracture. The triangular shape of the fibula is dictated by the insertion points of the muscles on the shaft. Obtain 3 views of the ankle (AP, lateral, and mortise) to look for ankle fracture or syndesmotic disruption. Position. The fracture occurs from a direct blow to the outside of the leg, from twisting the lower leg awkwardly and, most common, from a severe ankle sprain. Fibula Fracture - TeachMe Orthopedics For distal tibial fractures, fixation of the fibula: May aid in realignment or length restoration of the tibial fracture, Increases the stability of the tibial fracture repair (, Is performed with a 3.5-mm compression plate. Please . counterpart of LeFortWagstaffe fracture), medial sided swelling, tenderness, and ecchymosis not sensitive for medial stability, palpate proximal fibula for Maisonneuve fracture, most appropriate stress radiograph to assess competency of deltoid ligament, foot dorsiflexed and ER with tibia stabilized, more sensitive to injury than medial tenderness, ecchymosis, or edema, gravity stress radiograph is equivalent to manual stress radiograph, difficult for patients to tolerate in acute setting, it has also been reported that there is no actual correlation between syndesmotic injury and tibiofibular clear space or overlap measurements, normal <6 mm on both AP and mortise views, bisection of line through tibial anatomical axis and line through tip of both malleoli, shortening of lateral malleoli fractures can lead to increased talocrural angle, talocrural angle is not 100% reliable for estimating restoration of fibular length, can also utilize realignment of the medial fibular prominence with the tibiotalar joint, 25% of surgeons would change operative technique after CT, assess for anteromedial impaction of tibial plafond and talar articular cartilage injury, axial and sagittal views most useful to assess posterior malleolus, size and shape of posterior malleolus fragment, evaluate for soft tissue or cartilaginous injuries, positive anterior drawer

tip fractures of medial or lateral malleolus, bimalleolar or bimalleolar-equivalent fracture, posterior malleolar fracture with > 25% or > 2mm step-off, goal of treatment is stable anatomic reduction with restoration of mortise, see fracture patterns below for specific treatment, direct reduction of medial and lateral malleolus fractures, indirect reduction of posterior malleolus, facilitates direct reduction of posterior malleolus, common approach for fibula ORIF syndesmotic fixation, concomitant access to posterior fibula and posterior malleolus, access to medial malleolus and posterior malleolus, common approach for medial malleolus ORIF, prolonged recovery expected (2 years to obtain final functional result), anatomic reduction is considered most important factor for satisfactory outcome, ORIF superior to closed treatment of bimalleolar fractures, improved incisional perfusion with Allgwer-Donati sutures, proper braking response time (driving) returns to baseline at 9 weeks after surgery, braking travel time is significantly increased until 6 weeks after initiation of weight bearing in both long bone and periarticular fractures of lower extremity, severe open fractures with gross contamination, poor soft tissue requiring close monitoring, lower risk of redislocation and skin complication in ankle fracture dislocation vs splint, isolated medial malleolus fracture without talar shift, deep deltoid inserts on posterior colliculus, good outcomes with >95% union rate for isolated injury, lag screw fixation stronger if placed perpendicular to fracture line, bicortical 3.5 mm fully-threaded screw (lag by technique) superior to unicortical 4.0 mm partially-threaded screw (lag by design), > 4-5 mm of medial clear space widening on stress views considered unstable, recent studies show deep deltoid intact with 8-10 mm of widening on stress view, open reduction and internal fixation (ORIF), presence of talar shift on static or stress view (bimalleolar equivalent), one-third tubular or anatomic distal fibular plate, stiffest fixation construct for the fibula is a locking plate, posterior antiglide plating is biomechanically superior to lateral plate, disadvantage of peroneal tendon irritation if plate too distal, newer implants have improved axial and rotational control with distal/proximal fixation, useful for poor soft-tissue envelopes or high risk for wound-healing complication, similar outcomes with operative and non-operative treatment if stable mortise, Bimalleolar-Equivalent Fracture (deltoid ligament tear with fibular fracture), low demand and unable to tolerate surgery, lateral malleolus fracture with talar shift (static or stress view), assess syndesmotic stability after fixation of lateral malleolus, not necessary to repair medial deltoid ligament, explore medially if unable to reduce mortise and deltoid ligament potentially interposed, lower rate of nonunion and fracture displacement with operative treatment, Bimalleolar (MEDIAL AND LATERAL) Fracture, low demand and unable to undergo surgical intervention, any displacement or talar shift (static or stress view), size should be calculated on CT since plain radiographs are unreliable, interval between FHL and peroneal tendons, common approach since posterior malleolus fractures are frequently posterolateral, decision of approach will depend on location of fracture, degree of displacement, and need for fibular fixation, stiffness of syndesmosis restored to 70% normal with isolated fixation of posterior malleolus vs 40% with isolated, PITFL may remain attached to posterior malleolus and syndesmotic stability may be restored with isolated posterior malleolar fixation, stress examination of syndesmosis still required after posterior malleolar fixation, 40-90% of distal third spiral tibia fractures have an associated posterior malleolus fracture, rare fracture-dislocation of ankle where fibula is entrapped behind tibia and is irreducible, posterolateral ridge of the distal tibia hinders reduction of the fibula, open reduction of fibula and internal fixation is required, fracture-dislocation of the ankle due to hyperplantarflexion, main feature is a vertical shear fracture of the posteromedial tibial rim, double cortical density at the inferomedial tibial metaphysis, ORIF of posterior malleolus with antiglide plating, primary closure at index procedure can be performed in appropriately-selected grade I, II, and IIIA open fractures in otherwise healthy patients without gross contamination, higher incidence with higher fibula fractures, fixation usually not required when fibula fracture within 4.5 cm of plafond, measure tibiofibular clear space 1 cm above joint, abduction/external rotation stress of dorsiflexed foot, lateral stress radiograph has greater interobserver reliability than an AP/mortise stress film, instability of the syndesmosis is greatest in the anterior-posterior direction, patient placed in lateral decubitus position, similar effectiveness to manual ER stress test, bone hook around fibula used to pull while placing counter traction on tibia, tibiofibular clear space (AP) greater than 5 mm, length and rotation of fibula must be accurately restored, "Dime sign"/Shentons line to determine length of fibula, fixing lateral and/or posterior malleolus first my obviate need for syndesmotic fixation, outcomes are strongly correlated with anatomic reduction, maximum dorsiflexion not required during screw placement (over-tightening), open reduction required if closed reduction unsuccessful or questionable, one or two cortical screw(s) or suture-button devices 2-4 cm above joint, angled posterior to anterior 20-30 degrees (fibula posterior to tibia), suture button has lower rate of malreduction and reoperation rate than screws, no difference in outcomes seen with hardware maintenance (breakage or loosening) or removal at 1 year, outcome may be worse with maintenance of intact screws, screws should be maintained in place for at least 8-12 weeks, must remain non-weight bearing, as screws are not biomechanically strong enough to withstand forces of ambulation, any postoperative malalignement or widening should be treated with open debridement, reduction, and fixation, Diabetic Ankle Fractures (with or without Neuropathy), poor circulation impairs wound and fracture healing, multiple quadricortical syndesmotic screws (even in the absence of syndesmotic injury), tibiotalar Steinmann pins or hindfoot nailing, augment with intramedullary fibula K-wires, stiffer, more rigid fibular plates (instead of 1/3 tubular plates), maintain non-weightbearing postop for 8-12 weeks (instead of 4-8 weeks in normal patients), largest risk factor for diabetic patients is presence of, articular impaction of tibial plafond in SAD injuries should be addressed at time of surgery, corrective osteotomy requires obtaining anatomic fibular length and mortise correction for optimal outcomes, Loss of dorsiflexion with posterior fixation, rare with anatomic reduction and fixation, very common in "log-splitter" type injuries (trans-syndesmotic fracture-dislocations in which the talus is driven into the distal tibiofibular articulation), superficial peroneal nerve injury (10-15%), At risk with lateral approach to distal fibula, posterolateral, and anterior/anterolateral approaches, Two terminal nerve branches that innervate dorsum of the foot, protruding screw head in most distal hole of fibula plate, at risk with posterior
