The tibia is a larger bone on the inside, and the fibula is a smaller bone on the outside. Long-distance runners and hikers are at risk for stress fractures. 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. (0/3). Diagnosis can be suspected with a knee effusion and a positive dial test but MRI studies are required for confirmation. posterior border of the biceps femoris tendon, Shoulder Anterior (Deltopectoral) Approach, Shoulder Lateral (Deltoid Splitting) Approach, Shoulder Arthroscopy: Indications & Approach, Anterior (Brachialis Splitting) Approach to Humerus, Posterior Approach to the Acetabulum (Kocher-Langenbeck), Extensile (extended iliofemoral) Approach to Acetabulum, Hip Anterolateral Approach (Watson-Jones), Hip Direct Lateral Approach (Hardinge, Transgluteal), Hip Posterior Approach (Moore or Southern), Anteromedial Approach to Medial Malleolus and Ankle, Posteromedial Approach to Medial Malleolus, Gatellier Posterolateral Approach to Ankle, Tarsus and Ankle Kocher (Lateral) Approach, Ollier's Lateral Approach to the Hindfoot, Medial approach to MTP joint of great toe, Dorsomedial Approach to MTP Joint of Great Toe, Posterior Approach to Thoracolumbar Spine, Retroperitoneal (Anterolateral) Approach to the Lumbar Spine, may be done supine with bump under affected limb or in lateral position, Make linear longitudinal incision along the, may extend proximally to a point 5cm proximal to the fibular head, begin proximally and incise the fascia taking great care not to damage the common peroneal nerve, about 10-12 cm above the tip of the lateral malleolus, the superficial peroneal nerve pierces the fascia, distal - may be extended distally to become continuous with, Kocher lateral approach to the ankle and tarsus, susceptible to injury at junction of middle and distal third of leg, if injured will cause numbness on the dorsum of the foot. Common proximal tibial fractures include: This type of fracture takes place in the middle, or shaft (diaphysis), of the tibia. Fibula fractures, including ankle fractures, are among the most commonly encountered fractures in orthopaedics (. The following article will focus on fractures of the fibula that are proximal to the ankle joint and the treatment of such fractures. Pathophysiology.

Fibula and its ligaments in load transmission and ankle joint stability. compared to IM nailing of tibia fractures: increased risk of wound complications and hardware irritation, similar rates of union in closed fractures, greater radiation exposure intraoperatively, risk of damage to the superficial peroneal nerve during percutaneous screw insertion, holes 11,12, and 13 (proximally) of a 13 hole plate place nerve at risk, prior studies have demonstrated some use in, outcomes (controversial, as recent studies have not fully supported these findings), decrease need for subsequent autologous bone-grafting, decrease need for secondary invasive procedures, no current scoring system to determine if an amputation should be performed, relative indications for amputation include, most important predictor of eventual amputation is the severity of ipsilateral extremity, most important predictor of infection other than early antibiotic administration is transfer to definitive trauma center, study shows no significant difference in functional outcomes between amputation and salvage, loss of plantar sensation is not an absolute indication for amputation, functional (patellar tendon bearing) brace at around 4 weeks, close follow-up with repeat radiographs to ensure no displacement, can wedge cast to correct slight deformity, within 24 hours of initial injury to decrease risk of infection, sharp debridement of nonviable soft tissue & bone, thorough irrigation of contaminated wound, immediate closure of open wounds is acceptable if minimal contamination is present and is performed without excessive skin tension. performed with the hip flexed 45, knee flexed 80, and foot is ER 15. There are several ways to classify tibia and fibula fractures. Position. 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. Summary. Or an external fixator may be used to surgically repair the wound. ; Patients may report a history of direct (motor vehicle crash or axial loading) or indirect . Mechanism of Injury [edit | edit source]. 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. 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. 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). The injury produces pain, tenderness, and swelling of the ankle making weight-bearing difficult or impossible. Sproule JA, Khalid M, OSullivan M, et al. 2023 Lineage Medical, Inc.

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. if skin cannot be closed, vac-assisted closure should be considered in short-term. However, there is a risk of full or partial early closure of the growth plate. (1/3), Level 3 Symptoms of a fibula stress fracture.

The injury is common in athlete who is engaged in collision or contact sport . There is very limited mobility between this syndesmosis. lawnmower) or iatrogenic during surgical dissection, (patterned off adult Lauge-Hansen classification), Adduction or inversion force avulses the distal fibular epiphysis (SH I or II), Rarely occurs with failure of lateral ligaments, Further inversion leads to distal tibial fracture (usually SH III or IV, but can be SH I or II), Occasionally can cause fracture through medial malleolus below the physis, Plantarflexion force displaces the tibial epiphysis posteriorly (SH I or II), Thurston-Holland fragment is composed of the posterior tibial metaphysis and displaces posteriorly, External rotation force leads to distal tibial fracture (SH II), Thurston-Holland fragment displaces posteromedially, Easily visible on AP radiograph (fracture line extends proximally and medially), Further external rotation leads to low spiral fracture of fibula (anteroinferior to posterosuperior), External rotation force leads to distal tibial fracture (SH I or II) and transverse fibula fracture, Occasionally can be transepiphyseal medial malleolus fracture (SH II), Distal tibial fragment displaces laterally, Thurston-Holland fragment is lateral or posterolateral distal tibal metaphysis, Can be associated with diastasis of ankle joint, Leads to SH V injury of distal tibial physis, Can be difficult to identify on initial presentation (diagnosis typically made when growth arrest is seen on follow-up radiographs), distal fibula physeal tenderness may represent non-displaced SHI, full-length tibia (or proximal tibia) to rule out Maisonneuve-type fracture, assess fracture displacement (best obtained post-reduction), non-displaced (< 2mm) isolated distal fibular fracture, displaced (> 2mm) SH I or II fracture with, acceptable closed reduction (no varus, < 10 valgus, < 10 recurvatum/procurvatum, < 3mm physeal widening), or II fracture with unacceptable closed reduction (varus, > 10 valgus, > 10 recurvatum/procurvatum, > 3mm physeal widening) and > 2 years of growth remaining, displaced SH I or II fracture with unacceptable closed reduction (varus, > 10 valgus, > 10 recurvatum/procurvatum, > 3mm physeal widening) and < 2 years of growth remaining, requires adequate sedation and muscle relaxation, only attempt reduction two times to prevent further physeal injury, NWB short-leg cast if isolated distal fibula fracture, NWB long-leg cast if distal tibia fracture, interposed periosteum, tendons, or neurovascular structures, percutaneous manipulation with K wires may aid reduction, open reduction may be required if interposed tissue present, transepiphyseal fixation best if at all possible, high rate associated with articular step-off > 2mm, medial malleolus SH IV fractures have the highest rate of growth disturbance, 15% increased risk of physeal injury for every 1mm of displacement, can represent periosteum entrapped in the fracture site, partial arrests can lead to angular deformity, distal fibular arrest results in ankle valgus defomity, medial distal tibia arrest results in varus deformity, complete arrests can result in leg-length discrepancy, if < 20 degrees of angulation with < 50% physeal involvement and > 2 years of growth remaining, bar of >50% physeal involvement in a patient with at least 2 years of growth, fibular epiphysiodesis helps prevent varus deformity, if < 50% physeal involvement and > 2 years of growth remaining, contralateral epiphysiodesis if near skeletal maturity with significant expected leg-length discrepancy, typically seen in posteriorly displaced fractures, can occur after triplane fractures, SH I or II fractures, usually leads to an increased external foot rotation angle, anterior angulation or plantarflexion deformity, occurs after supination-plantarflexion SH II fractures, occurs after external rotation SH II fractures, treatment options include physical therapy, psychological counseling, drug therapy, sympathetic blockade, Pediatric Pelvis Trauma Radiographic Evaluation, Pediatric Hip Trauma Radiographic Evaluation, Pediatric Knee Trauma Radiographic Evaluation, Pediatric Ankle Trauma Radiographic Evaluation, Distal Humerus Physeal Separation - Pediatric, Proximal Tibia Metaphyseal FX - Pediatric, Chronic Recurrent Multifocal Osteomyelitis (CRMO), Obstetric Brachial Plexopathy (Erb's, Klumpke's Palsy), Anterolateral Bowing & Congenital Pseudoarthrosis of Tibia, Clubfoot (congenital talipes equinovarus), Flexible Pes Planovalgus (Flexible Flatfoot), Congenital Hallux Varus (Atavistic Great Toe), Cerebral Palsy - Upper Extremity Disorders, Myelodysplasia (myelomeningocele, spinal bifida), Dysplasia Epiphysealis Hemimelica (Trevor's Disease). Tibia and fibula are the two long bones located in the lower leg. low energy (fall from standing, twisting, etc) result of indirect, torsional injury. - Radiographic Studies. Fractures of the fibular shaft occurring without ankle injury nearly always are associated with tibial shaft fractures. There are three types of tibial shaft fractures: These fractures occur at the ankle end of the tibia. Epiphyseal fractures of the distal ends of the tibia and fibula. Are you sure you want to trigger topic in your Anconeus AI algorithm? These types include: lateral malleolus . Treatment may be nonoperative or operative depending on patient age, fracture displacement, and fracture morphology. Repair of the deltoid ligament tear is not believed to be necessary (. Correlation of interosseous membrane tears to the level of the fibular fracture. The deep peroneal nerve is responsible for sensation over the first dorsal webspace. 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. 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. Are you sure you want to trigger topic in your Anconeus AI algorithm? Read More, Copyright 2007 Lippincott Williams & Wilkins. Tibia and fibula fracturesare characterized as either low-energy or high-energy. Anteroposterior (A) and lateral (B) radiographic evaluation of the entire length of the fibula is essential to avoid missing a Maisonneuve fracture and the associated syndesmotic injury. 2023 Lineage Medical, Inc. All rights reserved, Ohio Health Orthopedic Trauma and Reconstructive Surgery, 2. (0/3), Level 5 One reason for this may be the treatment for the vast majority of isolated fibula shaft fractures is non-operative - this contrasts with the treatment of lateral malleolus fractures, which, although it is part of the fibula, technically, are categorized as ankle fractures and, therefore, have different treatment principles. The treatment of an open tibial fracture starts with antibiotics and a tetanus shot to address the risk of infection. (0/3), Level 1 One of the common types in children is the distal tibial metaphyseal fracture. Treatment for tibia and fibula fractures ranges from casting to surgery, depending on the type and severity of the injury. Fractures that involve syndesmotic injury or ankle or knee fracture often require surgical treatment. identify joint involvement and articular step-off (>25%, >2mm requires ORIF) . Stress Fractures of the Fibula . - C3 proximal fracture of the fibula. Diagnosis is made with plain radiographs of the ankle. 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.
