Orthobullets Team Trauma - Ankle Fractures; Listen Now 38:12 min. At Another Johns Hopkins Member Hospital: Tibia fractures are the most common lower extremity fractures in children. There are three types of tibial shaft fractures: These fractures occur at the ankle end of the tibia. 2023 Lineage Medical, Inc. All rights reserved. However, there is a risk of full or partial early closure of the growth plate. Posterior tibiofibular ligament rupture or avulsion of posterior malleolus, 4. Diagnosis is made with plain radiographs of the ankle. (0/3), Level 5 The fibula and tibia connect via an interosseous membrane, which attaches to a ridge on the medial surface of the fibula. The pain may begin gradually. (0/3). Orthobullets Technique Guides cover information that is "not testable" on ABOS Part I: Preparation. Stress Fractures of the Fibula . They are also called tibial plafond fractures. Please Login to add comment. 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. Fibula and its ligaments in load transmission and ankle joint stability. (0/3), Level 2 Are you sure you want to trigger topic in your Anconeus AI algorithm? Fourth and fifth proximal/middle phalangeal shaft fractures and select metacarpal fractures. Are you sure you want to trigger topic in your Anconeus AI algorithm? Lateral short oblique fibula fracture (anteroinferior to posterosuperior), 3. The superficial peroneal nerve innervates the musculature of the lateral compartment and is responsible for eversion and, to a much milder degree, plantarflexion of the foot. The proximal fibula is the insertion point for the biceps femoris posterolaterally, the soleus posteriorly, and the peroneus longus and extensor digitorum longus anteiorly. Talofibular sprain or distal fibular avulsion, 1. Surgery may also be needed depending on the wound size, amount of tissue damage and any vascular (circulation) problems. 2021 Orthopaedic Trauma & Fracture Care: Pushing the Envelope, Undecided The injury is common in athlete who is engaged in collision or contact sport . (1/3), Level 3 Tornetta P, III, Spoo JE, Reynolds FA, et al. Pearls/pitfalls. Posterolateral corner (PLC) injuries are traumatic knee injuries that are associated with lateral knee instability and usually present with a concomitant cruciate ligament injury (PCL > ACL). Generally, fibula fractures do well, and most patients have normal function at long-term follow-up (. Fractures of the proximal head and neck of the fibula are associated with substantial damage to the knee (. The diagnosis is made by x-raying the ankle. Nielson JH, Sallis JG, Potter HG, et al. For prognostic reasons, severely comminuted, contaminated barnyard injuries, close-range shotgun/high-velocity gunshot injuries, and open fractures presenting over 24 hours from injury have all been included in the grade III group. The following article will focus on fractures of the fibula that are proximal to the ankle joint and the treatment of such fractures. One reason for this may be the treatment for the vast majority of isolated fibula shaft fractures is non-operative - this con Fractures of the fibular shaft occurring without ankle injury nearly always are associated with tibial shaft fractures. Fractures may involve the knee, tibiofibular syndesmosis, tibia, or ankle joint. Accept (0/3), Level 1 check firmness of each compartment to evaluate for compartment syndrome, dorsalis pedis and posterior tibial pulses - compare to contralateral side, CT angiography indicated if pulses not dopplerable, full-length AP and lateral views of the affected tibia, AP, lateral and oblique views of ipsilateral knee and ankle, repeat radiographs recommended after splinting or fracture manipulation, intra-articular fracture extension or suspicion of plateau/plafond involvement, used to exclude posterior malleolar fracture, high variation in reported incidence of posterior malleolus fracture with distal 1/3 spiral tibia fractures (25-60%), closed, low energy fractures with acceptable alignment, < 10 degrees anterior/posterior angulation, certain patients who may be non-ambulatory (ie. if skin cannot be closed, vac-assisted closure should be considered in short-term. Maisonneuve fracture refers to a combination of a fracture of the proximal fibula together with an unstable ankle injury (widening of the ankle mortise on x-ray), often comprising ligamentous injury ( distal tibiofibular syndesmosis , deltoid ligament) and/or fracture of the medial malleolus. accounts for 25-40% of all physeal injuries (second most common), accounts for 5% of all pediatric fractures, pediatric ankle fractures are a common injury that includes, twisting injury, i.e. 2023 - TeachMe Orthopedics. - C1 diaphyseal fracture of the fibula, simple. Repair of the deltoid ligament tear is not believed to be necessary (. If a medial malleolar fracture is present, it should be repaired with open fixation. This may lead to a growth arrest in the form of leg length discrepancy or other deformity. Treatment for tibia and fibula fractures ranges from casting to surgery, depending on the type and severity of the injury. If patient is unable to participate in examination and concern is high clinically, intracompartmental compartment measurements should be performed, floating knee is an indication for antegrade tibial nailing and retrograde femoral nailing, distal 1/3 and spiral tibial shaft fractures, tibial shaft is triangular in cross-section, proximal medullary canal is centered laterally, important for start point with IM nailing, anteromedial tibial crest is composed of dense, cortical bone and rests in a subcutaneous position, making it useful as a landmark, tibial tubercle sits anterolaterally, approximately 3 cm distal to joint line, gerdy's tubercle lies laterally on proximal tibia, pes anserinus lies medially on proximal tibia, attachment of sartorius, semitendinosus, and gracilis, superficial medial collateral ligament (MCL) attaches approximately 5-7 cm distal to joint line deep to the pes anserinus, adjacent fibula supports attachments for the lateral collateral ligament complex and long head of biceps femoris, tibia is responsible for about 80-85% of lower extremity weight-bearing, fibrous structure interconnecting tibia/fibula which provides axial stability, fibula rests in distal tibial incisura and is stabilized by syndesmotic ligaments, anterior inferior tibiofibular ligament (AITFL), posterior inferior tibiofibular ligament (PITFL), inferior transverse tibiofibular ligament (ITL), interosseous ligament (IOL) - continuation of interosseus membrane, syndesmotic stability can be affected by distal, spiral tibial shaft fractures, Fracture classification is primarily descriptive based on pattern and location, Oestern and Tscherne Classification of Closed Fracture Soft Tissue Injury, Injuries from indirect forces with negligible soft-tissue damage, Superficial contusion/abrasion, simple fractures, Deep abrasions, muscle/skin contusion, direct trauma, impending compartment syndrome, Excessive skin contusion, crushed skin or destruction of muscle, subcutaneous degloving, acute compartment syndrome, and rupture of major blood vessel or nerve, Gustilo-Anderson Classification of Open Tibia Fractures, Limited periosteal stripping, clean wound < 1 cm, Minimal periosteal stripping, wound >1 cm in length without extensive soft-tissue injury damage. It is the main weight-bearing bone of the two. These fractures should be treated operatively with open plating of the fibula fracture and syndesmotic screw placement. 2023 Lineage Medical, Inc. All rights reserved. Please . Fibular fractures in adults are typically due to trauma. - C3 proximal fracture of the fibula. Maisonneuve fractures with syndesmotic injury imply injury to the medial side of the ankle joint. With an associated knee injury, patients have pain and swelling of the knee joint. Tibia and fibula fracturesare characterized as either low-energy or high-energy. Approximately 7-16% knee ligament injuries are to the posterolateral ligamentous complex, only 28% of all PLC injuries are isolated, usually combined with cruciate ligament injury (PCL > ACL), common cause of ACL reconstruction failure, contact and noncontact hyperextension injuries, three major static stabilizers of the lateral knee, most anterior structure inserting on the fibular head, originates at the musculotendinous junction of the popliteus, meniscofemoral and meniscotibial ligaments, inserts on the posterior aspect of the fibula posterior to LCL, popliteus works synergistically with the PCL to control, popliteus and popliteofibular ligament function maximally in knee flexion to resist external rotation, LCL is primary restraint to varus stress at 5 (55%) and 25 (69%) of knee flexion, arcuate complex includes the static stabilizers: LCL, arcuate ligament, and popliteus tendon, Patellar retinaculum, patellofemoral ligament, 0-5 mm of lateral opening on varus stress, 0-5 rotational instability on dial test, Sprain, no tensile failure of capsuloligamentous structures, 6-10 mm of lateral opening on varus stress, 6-10 rotational instability on dial test, Partial injuries with moderate ligament disruption, > 10 mm of lateral opening on varus stress, no endpoint, > 10 rotational instability on dial test, no endpoint, often have instability symptoms when knee is in full extension, difficulty with reciprocating stairs, pivoting, and cutting, varus thrust or hyperextension thrust with ambulation, varus laxity at 0 indicates both LCL and cruciate (ACL or PCL) injury, positive when lower leg falls into external rotation and recurvatum when leg suspended by toes in supine patient, more consistent with combined ACL and PLC injuries. The fibula supports the tibia and helps stabilize the ankle and lower leg muscles. Follow-up/referral. 2023 Lineage Medical, Inc. All rights reserved. Ulnar side of hand. There are several ways to classify tibia and fibula fractures. Physical examination shows point tenderness and swelling in the area of fracture. 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 or talar tilt test, increased medial clear space or tibiofibular diastasis on stress view, inability or weakness with plantar flexion, increased resting dorsiflexion when prone with knees bent, Chaput fragment, Volkmann fragment, medial malleolus, central impaction, high energy with extensive soft tissue injury, 25% open, x-ray shows dislocation of talus from calcaneous or navicular bone, avulsion 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 medial malleolus screw placement, Excellent for stable ankle fractures treated nonoperatively, Outcomes following operative treatment generally very favorable, 90% mild/no ankle pain with minimal limitations and near full functional recovery at 1 yr, Proximal Humerus Fracture Nonunion and Malunion, Distal Radial Ulnar Joint (DRUJ) Injuries.
