If the reduction is unstable (i.e., the position is not maintained after traction is released), splinting should not be used to hold the reduction, and referral is indicated. Physical examination findings typically include tenderness to palpation, swelling, ecchymosis, and sometimes crepitation at the fracture site. 11(2): p. 121-3. 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). Smooth K-wires or screw osteosynthesis can be used to stabilize the fragment. Referral is indicated if buddy taping cannot maintain adequate reduction. Patients with Jones fractures should be referred if there is more than 2 mm of displacement, if conservative therapy is ineffective after 12 weeks of immobilization and radiography reveals nonunion, or if the patient is an athlete or is highly active.2,13,2022, Toe fractures are the most common fractures of the foot.23,24 Most fractures involve minimal displacement and are treated nonsurgically. All rights reserved. Proximal interphalangeal joint (PIPJ) dislocation is one of the most common hand injuries. In this type of injury, the tendon that attaches to the base of the fifth metatarsal may stretch and pull a fragment of bone away from the base. 21(1): p. 31-4. 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. Search dates: February and June 2015. Narcotic analgesics may be necessary in patients with first-toe fractures, multiple fractures, or fractures requiring reduction. This is called internal fixation. Returning to activities too soon can put you at risk for re-injury. Surgical fixation involves Kirchner wires or very small screws. (OBQ05.226) Proximal fifth metatarsal fractures have different treatments depending on the location of the fracture. The thumb connects to the hand through the next joint, known as the metacarpophalangeal (MCP) joint. Thompson, T.M., et al., Foot injuries associated with all-terrain vehicle use in children and adolescents. Most commonly, the fifth metatarsal fractures through the base of the bone. (Right) An intramedullary screw has been used to hold the bone in place while it heals. Injury. 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. The most common symptoms of a fracture are pain and swelling. Metatarsal fractures are among the most common injuries of the foot that may occur due to trauma or repetitive microstress. The same mechanisms that produce toe fractures may cause a ligament sprain, contusion, dislocation, tendon injury, or other soft tissue injury. The use of musculoskeletal ultrasonography may be considered to diagnose subtle metatarsal fractures. Vollman, D. and G.A. If an avulsion fracture results in a large displaced fracture fragment, however, your doctor may need to do an open reduction and internal fixation with plates and/or intramedullary screws. A fractured toe may become swollen, tender, and discolored. The proximal phalanx is the toe bone that is closest to the metatarsals. 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. MB BULLETS Step 1 For 1st and 2nd Year Med Students. While celebrating the historic victory, he noticed his finger was deformed and painful. Diagnosis can be confirmed with orthogonal radiographs of the involve digit. If stable, the patient can be transitioned to a short leg walking cast or boot3,6 (Figures 411 and 5). Patients with these fractures should be referred to an orthopedist.2,3,6, The fifth metatarsal has the least cortical thickness of all the metatarsals.13 There are multiple strong ligamentous and capsular attachments surrounding the proximal fifth metatarsal; these allow stresses to be directed through this portion of the bone.13 Classically, fractures of the proximal fifth metatarsal can be classified based on anatomic location into one or more of three zones (Figure 7).3. During this time, it may be helpful to wear a wider than normal shoe. When performed on 18 children with distal radius-ulna fractures, P_STAR achieved near anatomic fracture alignment with no nerve or tendon injury, infection, or refracture. Proximal articular. If you experience any pain, however, you should stop your activity and notify your doctor. If the bone is out of place, your toe will appear deformed. Surgery may be delayed for several days to allow the swelling in your foot to go down. Follow-up/referral. MTP joint dislocations. Epidemiology Incidence 2017, Management of Proximal Phalanx Fractures & Their Complications, Cleveland Combined Hand Fellowship Lecture Series 2020-2021, PIP Fracture & Dislocation: Case of the Week - Shaan Patel, MD, Proximal Phalanx Fracture: Case of the Week - Michael Firtha, DO, Proximal Phalanx Fracture Surgery by Dr. Thomas Trumble, Ring Finger Proximal Phalanx Fracture in 16M, Fracture of the base of proximal phalanx of 5th finger. Turf Toe is a hyperextension injury to the plantar plate and sesamoid complex of the big toe metatarsophalangeal joint that most commonly occurs in contact athletic sports. Maffulli, N., Epiphyseal injuries of the proximal phalanx of the hallux. 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). AAOS does not endorse any treatments, procedures, products, or physicians referenced herein. Most fifth metatarsal fractures can be treated with weight bearing as tolerated, and immobilization in a cast or walking boot. Stress fractures of the base of the proximal phalanx have been reported in athletes and dances, but these are uncommon. Stress fractures can occur in toes. Proper . A stress fracture, however, may start as a tiny crack in the bone and may not be visible on a first X-ray. There is typically swelling, ecchymosis, and point tenderness to palpation at the fracture site. For athletes and other highly active persons, evidence shows earlier return to activity with surgical management; therefore, surgery is recommended.13,21,22 In contrast, patients treated with nonsurgical techniques should be counseled about longer healing time and the possibility that surgery may be needed despite conservative management.2,13,2022, Patients with fifth metatarsal tuberosity avulsion fractures should be referred to an orthopedist if there is more than 3 mm of displacement, if step-off is greater than 1 to 2 mm on the cuboid articular surface, or if a fragment includes more than 60% of the metatarsal-cuboid joint surface. Foot fractures are among the most common foot injuries evaluated by primary care physicians. To minimize the possibility of future disability, the position of the bone fragments after reduction should be as close to anatomic as possible. All material on this website is protected by copyright. Bite The Bullet, He Needs Long Term Function: Be The Hated Person - Robert Anderson, MD. The reduced fracture is splinted with buddy taping. PMID: 22465516. There should be at least three images of the affected toe, including anteroposterior, lateral, and oblique views, with visualization of the adjacent toes and of the joints above and below the suspected fracture location. Fracture position ideally will be maintained when traction is released, but in some cases the reduction can be held only with buddy taping. Injuries to this bone may act differently than fractures of the other four metatarsals. A fifth metatarsal tuberosity avulsion fracture can be treated acutely with a compressive dressing, then the patient can be transitioned to a short leg walking boot for two weeks, with progressive mobility as tolerated after initial immobilization. If the bone is out of place, your toe will appear deformed. Fractures of multiple phalanges are common (Figure 3). Radiographic evaluation is dependent on the toe affected; a complete foot series is not always necessary unless the patient has diffuse pain and tenderness. Deformity, decreased range of motion, and degenerative joint disease in this toe can impair a patient's functional ability. Copyright 2023 Lineage Medical, Inc. All rights reserved. If a fracture is present, it will typically be one of two types: a tuberosity avulsion fracture or a Jones fracture (i.e., proximal fifth metatarsal metadiaphyseal fracture). Phalanx Fractures are common hand injuries that involve the proximal, middle or distal phalanx. Copyright 2023 Lineage Medical, Inc. All rights reserved. 36(1)p. 60-3. Treatment involves immobilization or surgical fixation depending on location, severity and alignment of injury. Referral also should be considered for patients with other displaced first-toe fractures, unless the physician is comfortable with their management. A proximal phalanx is a bone just above and below the ball of your foot. Pediatrics, 2006. Diagnosis is made with plain radiographs of the foot. Proximal phalanx (finger) fracture Contents 1 Background The flexor digitorum superficialis (FDS) inserts at the middle of the phalanx and can cause rotational deformity [1] Extensor tendons and interosseous muscles commonly causes volar angulation [1] Clinical Features Finger pain Differential Diagnosis Hand and Finger Fractures Patients with lesser toe fractures with angulation of more than 20 in the dorsoplantar plane, more than 10 in the mediolateral plane, or more than 20 rotational deformity should also be referred.6,23,24. This material may not otherwise be downloaded, copied, printed, stored, transmitted or reproduced in any medium, whether now known or later invented, except as authorized in writing by the AAFP. Indications to treat proximal phalanx fractures operatively include all of the following EXCEPT: (OBQ12.49) We help you diagnose your Hand Proximal phalanx case and provide detailed descriptions of how to manage this and hundreds of other pathologies. Patients usually cannot bear full weight and sometimes will ambulate only on the medial aspect of the foot. MB BULLETS Step 2 & 3 For 3rd and 4th Year Med Students. She has no history of ankle or foot trauma, and medical history is significant only for delayed menarche. This joint sits between the proximal phalanx and a bone in the hand . Your video is converting and might take a while Feel free to come back later to check on it. Ulnar gutter splint/cast. Adjuvant imaging techniques to analyze fracture geometry and plan implant placement, will be discussed in detail. Illustrations of proximal interphalangeal joint (PIPJ) fracture-dislocation patterns. Fractures of the talus include fractures of the neck, body, medial or lateral process, and osteochondral injuries. The fifth metatarsal is the long bone on the outside of your foot. Advertisement Almost two-thirds of all bones in the feet belong to the toes; hence the risk of fracture in this part of the foot is much higher than the rest of the foot. (Left) X-ray shows a Jones fracture at the base of the fifth metatarsal (arrow). In children, a physis (i.e., cartilaginous growth center) is present in the proximal part of each phalanx (Figure 2). In many cases, anteroposterior and oblique views are the most easily interpreted (Figure 1, top and bottom). As your pain subsides, however, you can begin to bear weight as you are comfortable. Remodeling of the fracture callus generally produces an almost normal appearance of the bone over a matter of months (Figure 26-36). These tendons may avulse small fragments of bone from the phalanges; they also can be injured when a toe is fractured. Therefore, phalanges and digits adjacent to the fracture must be examined carefully; joint surfaces also must be examined for intra-articular fractures (Figure 3). Fractures can also develop after repetitive activity, rather than a single injury. Follow-up radiographs may be taken three to six weeks after the injury, but they generally do not influence treatment and probably are not necessary in nondisplaced toe fractures. Clinical Features For acute metatarsal shaft fractures, indications for surgical referral include open fractures, fracture-dislocations, multiple metatarsal fractures, intra-articular fractures, and fractures of the second to fifth metatarsal shaft with at least 3 mm displacement or more than 10 angulation in the dorsoplantar plane. 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 24(7): p. 466-7. Surgeons will learn to assess and evaluate phalangeal anatomy and fracture geometry. The first toe has only two phalanges; the second through the fifth toes generally have three, but the fifth toe sometimes can have only two (Figure 1). Smith, Epidemiology of lawn-mower-related injuries to children in the United States, 1990-2004. Epub 2012 Mar 30. Treatment for a toe or forefoot fracture depends on: Even though toes are small, injuries to the toes can often be quite painful. As the name implies a phalangeal fracture involves a fracture of any of the bones in the lesser toes. 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. Analytical, Diagnostic and Therapeutic Techniques and Equipment 43. Distal metaphyseal. and C.W. The metatarsals are the long bones between your toes and the middle of your foot. Epidemiology Incidence Examination should consist of a neurovascular evaluation and palpation of the foot and ankle. Hyperflexion or hyperextension injuries most commonly lead to spiral or avulsion fractures. The patient notes worsening pain at the toe-off phase of gait. The most common injury in children is a fracture of the neck of the talus. The nail should be inspected for subungual hematomas and other nail injuries. Concerns with delayed healing and/or high activity demands may result in your doctor recommending surgery for an acute Jones fracture as well. Fractures can result from a direct blow to the foot such as accidentally kicking something hard or dropping a heavy object on your toes. Each metatarsal has the following four parts: Fractures can occur in any part of the metatarsal, but most often occur in the neck or shaft of the bone. Interosseus muscles and lumbricals insert onto the base of the proximal phalanx and flex the proximal fragment. toe phalanx fracture orthobullets Surgery is required in the case of an open fracture, when there is significant displacement, or instability after reduction. More sensitive than an X-ray, an MRI can detect changes in the bone that may indicate a fracture. Content is updated monthly with systematic literature reviews and conferences. Patients have localized pain, swelling, and inability to bear weight on the lateral aspect of the foot. A 26-year-old professional ballet dancer presents with insidious onset of right midfoot pain which began 6 months ago. The collateral ligaments and volar plate at the metacarpophalangeal (MCP) joint stabilize the proximal portion and the extensor tendon pulls the distal fragment into extension. X-rays. A fracture, or break, in any of these bones can be painful and impact how your foot functions. If the wound communicates with the fracture site, the patient should be referred. Management is determined by the location of the fracture and its effect on balance and weight bearing.
