Referral should be strongly considered for patients with nondisplaced intra-articular fractures involving more than 25 percent of the joint surface (Figure 4).4 These fractures may lose their position during follow-up. Most broken toes can be treated without surgery. Patients with open toe fractures or fractures with overlying skin necrosis are at high risk for osteomyelitis. Distal phalangeal fractures may be complicated by nail bed injuries. Indications to treat proximal phalanx fractures operatively include all of the following EXCEPT: (OBQ12.49) A 55 year-old woman comes to you with 2 months of right foot pain. 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. Treatment may be nonoperative or operative depending on the specific metatarsal involved, number of metatarsals involved, and fracture displacement. Referral is indicated if buddy taping cannot maintain adequate reduction. In children, a physis (i.e., cartilaginous growth center) is present in the proximal part of each phalanx (Figure 2). 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). Unless it is fairly subtle, rotational deformity should be corrected by further manipulation. To check proper alignment, radiographs should be taken immediately after reduction and again seven to 10 days after the injury (three to five days in children).4 In patients with potentially unstable or intra-articular fractures of the first toe, follow-up radiographs should be taken weekly for two or three weeks to monitor fracture position. Want more? From an anatomic perspective, the foot is divided into three regions (figure 1A-C): Forefoot Metatarsal and phalangeal bones most common injuries to the skeletal system, distal phalanx > middle phalanx > proximal phalanx, 40-69 years old - machinery is most common, displacement of proximal phalanx fracture, proximal fragment flexed due to interossei, distal fragment extends due to central slip, dynamic stability from compressive forces during pinch and grip, passive stabiltiy from collateral ligament, terminal slip of EDC inserts on dorsal aspect of middle phalanx, dominant artery found on median side of phalanges (closer to midline), type III - unstable bicondylar or comminuted, due to inherent stability provided by an intact and prolonged FDS insertion, proximal fragment in extension (due to central slip), results from hyperextension injury or axial loading, unstable if > 40% articular surface involved, represents avulsion of collateral ligaments, usually stable due to nail plate dorsally and pulp volarly, often associated with laceration of nail matrix or pulp, shearing due to axial load, leading to fracture involving > 20% of articular surface, avulsion due tensile force of terminal tendon or FDP, leading to small avulsion fracture, terminal tendon attaches to proximal epiphyseal fragment, deformity (angular, rotation, shortening), proximal fragment pulled into flexion by interossei, distal fragment pulled into extension by central slip, apex volar angulation if distal to FDS insertion, apex dorsal angulation if proximal to FDS insertion, diagnosis confirmed by history, physical, and orthogonal radiographs, extraarticular fractures with < 10 angulation or < 2mm shortening and no rotational deformity, 3 weeks of immobilization followed by aggressive motion, extraarticular fractures with > 10 angulation or > 2mm shortening or rotational deformity, Unstable patterns include spiral, oblique, fracture with severe comminution, Eaton-Belsky pinning through metacarpal head, minifragment fixation with plate and/or lag screws, lag screws alone indicated in presence of long oblique fracture, nail matrix may be incarcerated in fracture and block reduction, distal phalanx fractures with nailbed injury, dorsal base fractures with > 25% articular involvement, displaced volar base fractures with large fragment and involvement of FDP, Apex volar angulation effectively shortens extensor tendon and limits extension of PIPJ, indicated when associated with functional impairment, corrective osteotomy at malunion site (preferred), metacarpal osteotomy (limited degree of correction), most atrophic and associated with bone loss or neurovascular compromise, Lunate Dislocation (Perilunate dissociation), Gymnast's Wrist (Distal Radial Physeal Stress Syndrome), Scaphoid Nonunion Advanced Collapse (SNAC), Carpal Instability Nondissociative (CIND), Constrictive Ring Syndrome (Streeter's Dysplasia), Thromboangiitis Obliterans (Buerger's disease).

If an acute subungual hematoma is present (less than 24 hours old), decompression may relieve pain substantially. Distal Phalanx Distal phalanx fractures are usually nondisplaced or comminuted fractures. 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). Diagnosis is made clinically with the inability to hyperextend the hallux MTP joint without significant pain and the inability to push off with the big toe. From an anatomic perspective, the foot is divided into three regions (figure 1A-C): Forefoot Metatarsal and phalangeal bones Web5th Metatarsal Base Fractures are among the most common fractures of the foot and are predisposed to poor healing due to the limited blood supply to the specific areas of the 5th metatarsal base. If this maneuver produces sharp pain in a more proximal phalanx, it suggests a fracture in that phalanx. WebPhalanx Dislocations are common traumatic injury of the hand involving the proximal interphalangeal joint (PIP) or distal interphalangeal joint (DIP). AO START. Referral also is recommended for children with first-toe fractures involving the physis.4 These injuries may require internal fixation.

Most toe fractures are caused by an axial force (e.g., a stubbed toe) or a crushing injury (e.g., from a falling object). 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: Which of the following acute fracture patterns would best be treated with open reduction and internal fixation?

Stable, nondisplaced toe fractures should be treated with buddy taping and a rigid-sole shoe to limit joint movement. 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.

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). Diagnosis can be confirmed with orthogonal radiographs of the involve digit. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. The first phalanx (great toe) is most frequently involved. Although often dismissed as inconsequential, toe fractures that are improperly managed can lead to significant pain and disability.

Referral is indicated in patients with circulatory compromise, open fractures, significant soft tissue injury, fracture-dislocations, displaced intra-articular fractures, or fractures of the first toe that are unstable or involve more than 25 percent of the joint surface. Although tendon injuries may accompany a toe fracture, they are uncommon. 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. Because it is the longest of the toe bones, it is the most likely to fracture. The middle finger is This topic review will discuss fractures of the proximal phalanx. Distal phalangeal fractures may be complicated by nail bed injuries. This topic review will discuss fractures of the proximal phalanx. Although referral rarely is required for patients with fractures of the lesser toes, referral is recommended for patients with open fractures, fracture-dislocations (Figure 5), displaced intra-articular fractures, and fractures that are difficult to reduce.

Diagnosis is made with plain radiographs of the foot.

Immobilization of the distal interphalangeal joint is required for 2 weeks post-operatively, High rates of post-operative infection are common, Open reduction via an approach through the nail bed leads to significant post-operative nail deformity, Range of motion of the DIP joint in the affected finger is usually less than 10 degrees post-operatively, Shoulder360 The Comprehensive Shoulder Course 2023, Type in at least one full word to see suggestions list, AO TRAUMA HAND NORTH AMERICA Master Class Series : Session 1: Phalangeal /Metacarpal Malunion, Proximal Interphalangeal (PIP) Joint Implant Arthroplasty - Extended (Feat. The skin should be inspected for open wounds or significant injury that may lead to skin necrosis. Displaced spiral fractures generally display shortening or rotation, whereas displaced transverse fractures may display angulation. However, overlying shadows often make the lateral view difficult to interpret (Figure 1, center). Fractures of the toe are one of the most common lower extremity fractures diagnosed by family physicians. Diagnosis can be made clinically and are confirmed with orthogonal radiographs. WebPhalanx Fractures are common hand injuries that involve the proximal, middle or distal phalanx. These fractures are commonly caused by trauma or crush injuries.

WebTurf 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. Hallux fractures. Therefore, phalanges and digits adjacent to the fracture must be examined carefully; joint surfaces also must be examined for intra-articular fractures (Figure 3). Toe fractures of this type are rare unless there is an open injury or a high-force crushing or shearing 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. The second through fifth toes have a proximal, middle and distal phalanx. The great toe has only a proximal and distal phalanx. The pull of these muscles occasionally exacerbates fracture displacement. Patients with intra-articular fractures are more likely to develop long-term complications. Diagnosis is made with plain radiographs of the foot. Treatment may be nonoperative or operative depending on the specific metatarsal involved, number of metatarsals involved, and fracture displacement. Dr. Boyer), Ring Finger Proximal Phalanx Fracture in 16M, Fracture of the base of proximal phalanx of 5th finger. To unlock fragments, it may be necessary to exaggerate the deformity slightly as traction is applied or to manipulate the fragments with one hand while the other maintains traction.

While many Phalangeal fractures can be treated non-operatively, some do require surgery. Fractures of the proximal phalanx can be complex owing to forces exerted on the fracture fragments by multiple muscles and tendons which often result in angular or rotational deformity.
