Pathophysiology. The fibula is one of the two long bones in the leg, and, in contrast to the tibia, is a non-weight bearing bone in terms of the shaft. They account for 10 to 15 percent of all pediatric fractures. Summary. Fractures may involve the knee, tibiofibular syndesmosis, tibia, or ankle joint. 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. Distal tibial physeal fractures in children that may require open reduction. Patients are followed at 1-month intervals with plain radiographs until the fractures are healed. Anterior tibiofibular ligament disruption, 3. 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. may be done supine with bump under affected limb or in lateral position. This may lead to a growth arrest in the form of leg length discrepancy or other deformity. Fractures of the fibula can be described by anatomic position as proximal, midshaft, or distal. 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). Follow-up/referral. 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). Patients with isolated fibular shaft fractures are instructed to bear partial weight. Diagnosis is made with plain radiographs of the ankle. Fractures that involve syndesmotic injury or ankle or knee fracture often require surgical treatment. Transverse comminuted fracture of the fibula above the level of the syndesmosis. Epiphyseal fractures of the distal ends of the tibia and fibula. Distal fibula fractures that involve the ankle joint are by far the most common fibula fractures (see . B2 w/ medial lesion (malleolus or ligament) B3 w/ a medial lesion and fracture of posterolateral tibia. traveling traction), placed in metaphyseal segment at the concavity of the deformity, posteriorly placed blocking screw in proximal fragment and laterally placed blocking screw in the metaphyseal fragment help direct the nail more centrally, avoiding valgus/procurvatum deformities, increase biomechanical stability of bone/implant construct by 25%, not associated with increased infections, wound complications, and nonunion compared to closed-nailing techniques, ensure fracture is reduced before reaming, overream by 1.0-1.5mm to facilitate nail insertion, confirm guide wire is appropriately placed prior to reaming, should be "center-center" in the coronal and sagittal planes distally at the physeal scar, anterior aspect of nail should be lined up with axis of tibia when inserting nail - typically should line up with 2nd metatarsal in absence of tibial deformity, statically lock proximal and distally for rotational stability, no indication for dynamic locking acutely, number of interlocking screws is controversial, two proximal and two distal screws in presence of <50% cortical contact, consider 3 interlock screws in short segment of distal or proximal shaft fracture, prefer multiplanar screw fixation in these short segments, lateral may have more soft tissue interference but may be preferred in setting of soft tissue/wound issues, generally, minimally invasive plating is used to preserve soft tissues, plate attached to external jig to allow for percutaneous insertion of screws, must ensure appropriate contour of plate to avoid malreduction, higher risk for wound issues, particularly in open fractures, superficial peroneal nerve (SPN) commonly at risk laterally, below knee amputation (BKA) vs. above knee amputation (AKA) based on degree of soft tissue damage, standard BKA vs. ertl/bone block technique, infrapatellar nailing with patellar tendon splitting and paratendon approach, suprapatellar nailing may have lower rate of anterior knee pain, more common if nail left proud proximally, lateral radiograph is best radiographic views to evaluate proximal nail position, pain relief unpredictable with nail removal, all tibial shaft fractures - between 8-10%, higher in proximal 1/3 tibia fractures - up to 50%, patellar tendon pulls proximal fragment into extension, while hamstring tendons and gastrocnemius pull the distal fragment into flexion (procurvatum), distal 1/3 fractures have a higher rate of valgus malunion with IM nailing compared to plating, definitive management with casting or external fixation, most common deformity is varus with nonsurgical management, varus malunion may place patient at risk for ipsilateral ankle pain and stiffness, starting point too medial with IM nailing, adequate reduction, proper start point when nailing, if malalignment is noted immediately after surgery, return to operating room is appropriate with removal of nail, reduction and nail reinsertion, if malunion is appreciated at later followup, eventual nail removal and tibial osteotomy can be considered, most appropriate for aseptic, diaphyseal tibial nonunions, oblique tibial shaft fractures have the highest rate of union when treated with exchange nailing, consider revision with plating in metaphyseal nonunions, BMP-7 (OP-1) has been shown equivalent to autograft, often used in cases of recalcitrant non-unions, compression plating has been shown to have a 92-96% union rate after open tibial fractures initially treated with external fixation, fibular osteotomy of tibio-fibular length discrepancy associated with healed or intact fibula, highest after IM nailing of distal 1/3 tibia fractures, increases risk of adjacent ankle arthrosis, should always assess rotation in operating room, obtain perfect lateral fluoroscopic image of knee, then rotate c-arm 105-110 degrees to obtain mortise view of ipsilateral ankle, may have reduced risk with adjunctive fibular plating, LISS plate application without opening for distal screw fixation near plate holes 11-13 put superficial peroneal nerve at risk of injury due to close proximity, saphenous nerve can be injured during placement of locking screws, transient peroneal nerve palsy can be seen after closed nailing, EHL weakness and 1st dorsal webspace decreased sensation, usually nonoperatively with variable recovery expected, severe soft tissue injury with contamination, longer time to definitive soft tissue coverage, may require I&D or eventual removal of hardware, use of wound vacuum-assisted closure does not decrease risk of infection, Proximal Humerus Fracture Nonunion and Malunion, Distal Radial Ulnar Joint (DRUJ) Injuries. Indications. Diaphyseal tibial fractures are the most common long bone fracture. Are you sure you want to trigger topic in your Anconeus AI algorithm? Obtain 3 views of the ankle (AP, lateral, and mortise) to look for ankle fracture or syndesmotic disruption. Posterolateral Corner Injury. Wang Q, Whittle M, Cunningham J, et al. One of the common types in children is the distal tibial metaphyseal fracture. Obtain AP and lateral views of the shafts of the tibia and fibula. Medial malleolus transverse fracture or disruption of deltoid ligament . The shaft of the fibula serves as origin for the peroneus longus, peroneus brevis, peroneus tertius, extensor digitorum longus, extensor hallucis longus, tibialis posterior, soleus and flexor hallucis longus. Diagnosis is made with plain radiographs of the ankle. 2023 Lineage Medical, Inc.

Diagnosis is made with plain radiographs of the ankle. Read More, Copyright 2007 Lippincott Williams & Wilkins. The fibular shaft is an origin for multiple muscles of the leg, including musclesof the anterior compartment (extensor digitorum longus, extensor hallucis longus, peroneus tertius), the lateral compartment (peroneus longus, peroneus brevis), the superficial posterior compartment (soleus), and the deep posterior compartment (tibialis posterior and flexor hallucis longus). bypass fracture, likely adjacent joint (i.e. Are you sure you want to trigger topic in your Anconeus AI algorithm? Common proximal tibial fractures include: This type of fracture takes place in the middle, or shaft (diaphysis), of the tibia. open 1/3 tibial shaft fracture with placement of proximal 1/3 tibia and calcaneus/metatarsal pins to span fracture), construct stiffness increased with larger pin diameter, number of pins on each side of fracture, rods closer to bone, and a multiplanar construct, incision from inferior pole of patella to just above tibial tubercle, identify medial edge of patellar tendon, incise, insert guidewire as detailed below and ream, can lead to valgus malalignment in proximal 1/3 tibial fractures, helps maintain reduction when nailing proximal 1/3 fractures, can damage patellar tendon or lead to patella baja (minimal data to support this), semiextended medial or lateral parapatellar, used for proximal and distal tibial fractures, skin incision made along medial or lateral border of patella from superior pole of patella to upper 1/3 of patellar tendon, knee should be in 5-30 degrees of flexion, choice to go medial or lateral is based of mobility of patella in either direction, identify starting point and ream as detailed below, suprapatellar nailing (transquadriceps tendon), easier positioning if additional instrumentation needed, more advantageous for proximal or distal 1/3 tibia fractures, starting guidewire is placed in line with medial aspect of lateral tibial spine on AP radiograph, just below articular margin on lateral view, in proximal 1/3 tibia fractures starting point should cheat laterally to avoid classic valgus/procurvatum deformity, ensure guidewire is aligned with tibia in coronal and sagittal planes as you insert, opening reamer is placed over guidewire and ball-tipped guidewire can then be passed, spanning external fixation (ie. Are you sure you want to trigger topic in your Anconeus AI algorithm? 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. Fractures of the fibular shaft occurring without ankle injury nearly always are associated with tibial shaft fractures. Sproule JA, Khalid M, OSullivan M, et al. Technique guides are not considered high yield topics for orthopaedic standardized exams including ABOS, EBOT and RC. If a fibula fracture is associated with a. (2/3), Level 4 B1 Isolated. This type of fracture usually results from high-energy trauma or penetrating wounds. Surgery may also be needed depending on the wound size, amount of tissue damage and any vascular (circulation) problems. There are several ways to classify tibia and fibula fractures. Tibia and fibula are the two long bones located in the lower leg. Fractures of the tibia and fibula are typically diagnosed through physical examination andX-rays of the lower extremities. Correlation of interosseous membrane tears to the level of the fibular fracture. Depending on the exact location, a proximal tibial fracture may affect the stability of the knee as well as the growth plate. Both the posterior and medial malleolus arepart of the distal end of the tibia. We'll assume you're ok with this, but you can opt-out if you wish. van Staa TP, Dennison EM, Leufkens HGM, et al. A splint or cast may be applied to increase comfort but is not essential. (0/3), Level 1 The following article will focus on fractures of the fibula that are proximal to the ankle joint and the treatment of such fractures. The injury produces pain, tenderness, and swelling of the ankle making weight-bearing difficult or impossible. 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. C2: diaphyseal fracture of the fibula, complex. Symptoms consist of pain in the calf area with local tenderness at a point on the fibula. They are also called tibial plafond fractures. The deep peroneal nerve innervates the musculature of the anterior compartment and is responsible for the dorsiflexion of the foot and toes. Ankle Fractures are very common fractures in the pediatric population that are usually caused by direct trauma or a twisting injury. The pain may begin gradually. Salter-Harris Type-IV injuries of the distal tibial epiphyseal growth plate, with emphasis on those involving the medial malleolus. Pain will usually have developed gradually over time, rather than at a specific point in time that the athlete can recognise as when the injury occurred.
