A walking cast with a toe platform may be necessary in active children and in patients with potentially unstable fractures of the first toe. Phalanx fractures: The most common foot fractures Phalanx fractures typically occur by crush injury, hyperextension, or direct axial force (eg, stubbing the toe). Treatment involves immobilization or surgical fixation depending on location, severity and alignment of injury. However, overlying shadows often make the lateral view difficult to interpret (Figure 1, center). Although often dismissed as inconsequential, toe fractures that are improperly managed can lead to significant pain and disability. An unmineralized physis is biomechanically weaker compared with the surrounding ligamentous structures and mature bone, which makes fractures about the physis likely. ClinPediatr (Phila), 2011. After the splint is discontinued, the patient should begin gentle range-of-motion (ROM) exercises with the goal of achieving the same ROM as the same toe on the opposite foot. The preferred splinting technique is to buddy tape the affected toe to an adjacent toe (Figure 7).4 Treatment should continue until point tenderness is resolved, usually at least three weeks (four weeks for fractures of the first toe). They can also result from the overuse and repetitive stress that comes with participating in high-impact sports like running, football, and basketball. (OBQ12.89) Turf Toe - Foot & Ankle - Orthobullets (Right) Several weeks later, there is callus formation at the site and the fracture can be seen more clearly. MB BULLETS Step 2 & 3 For 3rd and 4th Year Med Students. Common mechanisms of injury include: Axial loading (stubbing toe) Abduction injury, often involving the 5th digit Crush injury caused by a heavy object falling on the foot or motor vehicle tyre running over foot Less common mechanism: Bruising or discoloration your foot may be red or ecchymotic ("black and blue"), Loss of sensation an indication of nerve injury, Head which makes a joint with the base of the toe, Neck the narrow area between the head and the shaft, Base which makes a joint with the midfoot. Content is updated monthly with systematic literature reviews and conferences. Phalanx Fractures are common hand injuries that involve the proximal, middle or distal phalanx. Healing rates also vary considerably depending on the age of the patient and comorbidities. Recent studies have demonstrated that musculoskeletal ultrasonography and traditional radiography have comparable accuracy, sensitivity, and specificity in the diagnosis of foot and ankle fractures9,10 (Figure 1). Patient examination; . Most fractures can be seen on a routine X-ray. Patients with a proximal fifth metatarsal fracture often present after an acute inversion of the foot or ankle. Smooth K-wires or screw osteosynthesis can be used to stabilize the fragment. Tarsal phalanges fractures - OrthopaedicsOne Articles The patient notes worsening pain at the toe-off phase of gait. ROBERT L. HATCH, M.D., M.P.H., AND SCOTT HACKING, M.D. A radiograph, bone scan, and MRI are found in Figures A-C, respectively. If your doctor suspects a stress fracture but cannot see it on an X-ray, they may recommend an MRI scan. On exam, he is neurovascularly intact. Fractures of the toe are one of the most common lower extremity fractures diagnosed by family physicians. Proximal Phalanx Fracture Toe Orthobullets: What They Are And Why You 5th metatarsal most commonly fractured in adults, 1st metatarsal most commonly fractured in children less than 4 years old, 3rd metatarsal fractures rarely occur in isolation, 68% associated with fracture of 2nd or 4th metatarsal, peak incidence between 2nd and 5th decade of life, may have significant associated soft tissue injury, occurs with forefoot fixed and hindfoot or leg rotating, Lisfranc equivalent injuries seen with multiple proximal metatarsal fractures, consider metabolic evaluation for fragility fracture, shape and function similar to metacarpals of the hand, first metatarsal has plantar crista that articulates with sesamoids, muscular balance between extrinsic and intrinsic muscles, Metatarsals have dense proximal and distal ligamentous attachments, 2nd-5th metatarsal have distal intermetatarsal ligaments that maintain length and alignment with isolated fractures, implicated in formation of interdigital (Morton's) neuromas, multiple metatarsal fractures lose the stability of intermetatarsal ligaments leading to increased displacement, Classification of metatarsal fractures is descriptive and should include, look for antecedent pain when suspicious for stress fracture, foot alignment (neutral, cavovarus, planovalgus), focal areas or diffuse areas of tenderness, careful soft tissue evaluation with crush or high-energy injuries, evaluate for overlapping or malrotation with motion, semmes weinstein monofilament testing if suspicious for peripheral neuropathy, AP, lateral and oblique views of the foot, may be of use in periarticular injuries or to rule out Lisfranc injury, useful in detection of occult or stress fractures, second through fourth (central) metatarsals, non-displaced or minimally displaced fractures, evaluate for cavovarus foot with recurrent stress fractures, sagittal plane deformity more than 10 degrees, restore alignment to allow for normal force transmission across metatarsal heads, lag screws or mini fragment plates in length unstable fracture patterns, maintain proper length to minimize risk of transfer metatarsalgia, limited information available in literature, may lead to transfer metatarsalgia or plantar keratosis, treat with osteotomy to correct deformity, Majority of isolated metatarsal fractures heal with conservative management, Malunion may lead to transfer metatarsalgia, Posterior Tibial Tendon Insufficiency (PTTI). Most children with fractures of the physis should be referred, but children with selected nondisplaced Salter-Harris types I and II fractures may be treated by family physicians. Referral is recommended for patients with first-toe fracture-dislocations, displaced intra-articular fractures, and unstable displaced fractures (i.e., fractures that spontaneously displace when traction is released following reduction). Stable, nondisplaced toe fractures should be treated with buddy taping and a rigid-sole shoe to limit joint movement. Surgery is required in the case of an open fracture, when there is significant displacement, or instability after reduction. This website also contains material copyrighted by third parties. Proximal Phalanx Fracture Management. - Post - Orthobullets The use of musculoskeletal ultrasonography may be considered to diagnose subtle metatarsal fractures. A 39-year-old male sustained an index finger injury 6 months ago and has failed eight weeks of splinting. Indirect pull of the central slip on the distal fragment and the interossei insertions at the base of the proximal phalanx, Intrinsic muscle fibrosis and intrinsic minus contracture, PIP joint volar plate attenuation and extensor tendon disruption, Rupture of the central slip with attenuation of the triangular ligament and palmar migration of the lateral bands, Flexor tendon disruption with associated overpull of the extensor mechanism. DAVID BICA, DO, RYAN A. SPROUSE, MD, AND JOSEPH ARMEN, DO. Follow-up/referral. Proximal metaphyseal. Surgery is not often required. An avulsion fracture is also sometimes called a "ballerina fracture" or "dancer's fracture" because of the pointe position that ballet dancers assume when they are up on their toes. If an acute subungual hematoma is present (less than 24 hours old), decompression may relieve pain substantially. Stress fractures are typically caused by repetitive activity or pressure on the forefoot. After that, nonsurgical treatment options include six to eight weeks of short leg nonweight-bearing cast with radiographic follow-up to document healing at six to eight weeks.2,6,20 If evidence of healing is present (callus formation and lack of point tenderness) at that time, weight-bearing activity can progress gradually, along with physical therapy and rehabilitation. PMID: 22465516. Author disclosure: No relevant financial affiliations. Evidence has shown that, depending on symptoms, short leg walking boots are superior to short leg walking casts.18,19 Immobilization in a cast or boot is typically only needed for two weeks, with progressive ambulation and range of motion thereafter as tolerated. An MRI is performed and selected cuts are shown in Figures B and C. What is this patients diagnosis? Joint hyperextension, a less common mechanism, may cause spiral or avulsion fractures. An attempt at reduction and immobilization is made in the field by his unit physician assistant, and he returns to your office one week later. Physical examination findings typically include tenderness to palpation, swelling, ecchymosis, and sometimes crepitation at the fracture site. Anyone seeking specific orthopaedic advice or assistance should consult his or her orthopaedic surgeon, or locate one in your area through the AAOS Find an Orthopaedist program on this website. Following reduction, the nail bed of the fractured toe should lie in the same plane as the nail bed of the corresponding toe on the opposite foot. The most common phalanx fractures involve the border digits, namely, the index and small finger rays (Fig. Patients should limit icing to 20 minutes per hour so that soft tissues will not be injured. In an analysis of 339 toe fractures, 95% involved less than 2 mm of displacement and all fractures were managed conservatively with good outcomes.25, The most common mechanisms of injury are axial loading (stubbing) or crush injury. All Rights Reserved. There are 3 phalanges in each toe except for the first toe, which usually has only 2. CrossRef Google Scholar PubMed 7 DeVries, JG, Taefi, E, Bussewitz, BW, Hyer, CF, Lee, TH. The "V" sign (arrow) indicates dorsal instability. - See: Phalangeal Injury Menu: - Discussion: - fractures of the proximal phalanx are potentially the most disabling fractures in the hand; - direct blows tend to cause transverse or comminuted frx, where as twisting injury may cause oblique or spiral fracture; - proximal fragments are usually flexed by intrinsics while distal fragments are extended due to extrinsic compressive forces; In some cases, a Jones fracture may not heal at all, a condition called nonunion. The skin should be inspected for open fracture and if . (Right) An intramedullary screw has been used to hold the bone in place while it heals. Stress fractures have a more insidious onset and may not be visible on radiographs for the first two to four weeks after the injury. Open subtypes (3) Lesser toe fractures. Three muscles, viz. These include metatarsal fractures, which account for 35% of foot fractures.2,3 About 80% of metatarsal fractures are nondisplaced or minimally displaced, which often makes conservative management appropriate.4 In adults and children older than five years, fractures of the fifth metatarsal are most common, followed by fractures of the third metatarsal.5 Toe fractures, the most common of all foot fractures, will also be discussed. imbalance after flexor tendon repair seems to be thus, extensor tendon injuries occur frequently an in depth understanding of the intricate anatomy of the extensor mechanism is necessary to guide management careful counseling is helpful in Early surgical management of a Jones fracture allows for an earlier return to activity than nonsurgical management and should be strongly considered for athletes or other highly active persons. Stress fractures of the base of the proximal phalanx have been reported in athletes and dances, but these are uncommon. Go to: History and Physical The main component to focus on assessment are: History - handedness, occupation, time of injury, place of injury (work-related) 50(3): p. 183-6. Displaced fractures of the lesser toes should be treated with reduction and buddy taping. Metatarsal Fractures - Foot & Ankle - Orthobullets
