Volar plate sprain or partial tear occurs after a hyperextension injury of the finger. This is located in the ball of your foot or the metatarsalgia region. The patient complains of pain at the metacarpal-phalangeal joint (MPJ) of the small finger. The volar plate is a ligament located at the middle knuckle (proximal interphalangeal joint - PIPJ) of the finger. A volar plate, with locked distal fixation, is positioned such that there is balanced support across the distal fragment and that the proximal portion of the plate is centered upon the volar radius. Consecutive (1A) fat-suppressed T2-weighted images of the small finger MPJ from dorsal to palmar and a (1B) single fat-suppressed proton density-weighted axial image are provided. Volar Plate Avulsion Injury This is a hyperextension injury, which is essentially a ligamentous injury, although it may involve a portion of bone avulsed off by a ligament. It is necessary to reduce the nail plate under the eponychium, and if this cannot be performed, the plate can be removed. 45 Volar Dislocations of the Proximal Interphalangeal Joint Lisa L.

There may be a small piece of bone avulsed (pulled away) from the middle phalanx when this occurs. We found no ruptures in Group 2, perhaps … Plantar Plate Injury Overview: Plantar plate ligament: A plantar plate tear or a plantar plate injury refers to the ligaments that holds your metatarsal phalangeal joint together. The middle phalanx (P2) is dislocated or subluxated volarly and the dorsal lip is fractured. All injuries were characterized by volar comminution and impaction of the distal phalanx, with associated dorsal subluxation. This happens when the finger is bent backward too far (hyperextended). commonly seen with small avulsion fracture of the base of the middle phalanx; simple . Avulsion of the nail plate and injury to the nail bed is often associated with tuft fractures. Note the involvement of the central slip attachment (Ext) in the fracture. If a complete tear occurs, the ligament usually ruptures or tears from its attachment on the middle phalanx. Volar plate avulsion fracture (Figure 7) occurs after hyperextension injury to the PIP joint, often from a ‘jamming’ injury during ball sports. The volar plate and other ligaments of the PIP joint should also be scrutinized carefully for injury. www.aapsm.org.au / articles / plantar-plate-injury Tears of the plantar plate may be the most common cause of pain under the second metatarsophalangeal joint, though it can occur at any of the metatarsophalangeal joints. Demographics and functional outcome of toe fractures. As the deformity progresses, the cartilage in the joint capsule can become eroded, leading to arthritis and increased pain. What is the volar plate of the finger? The annual incidence of phalangeal fractures in children is 2.7 percent [ 4 ]. It is a structure on the palm side of your finger at the second joint down from the tip. If a complete tear occurs, the ligament usually ruptures or tears from its attachment on the middle phalanx. It is most commonly injured at the proximal phalanx interpahalangeal (PIP) joint which is anatomically more … Clinical History: A 16 year-old male presents for MRI of the hand following a wrestling injury. Severe collateral ligament injury is uncommon in conjunction with volar plate instability but must be recognized and treated where indicated. catching a ball. There may be a small piece of bone avulsed (pulled away) from the middle phalanx when this occurs. It is initiated by wear debris from prosthetic implants. These injuries can also lead to a fracture (break) called an avulsion fracture. Am Fam Physician, 2003. gressive attenuation of the volar plate.Late-stagesecondarydeformi-ty includes a zigzag collapse pattern (Figure 6). It is also referred to as predislocation syndrome, crossover toe deformity and floating toe syndrome. The plate used in Group 1 is prominent at the watershed line of the distal part of the radius, which may increase the risk of tendon injury. The distal metaphysis, which anchors the complex nail matrix and nail plate, is often affected by distal fractures. Periprosthetic osteolysis is a common mode of total hip arthroplasty failure. A 20-year-old football player presents with a one week history of right index finger pain which started after his hand got caught in a face mask during a tackle. hyperextension deformity; middle phalanx remains in contact with co Chronic Plantar Plate Injury. Other etiologies of pain at the base of the thumb include de Quer-vain tenosynovitis of the first dorsal compartment, flexor carpi radialis (FCR) tendinitis, and carpal tunnel syndrome. Read more » The volar plate is a ligament which sits at the front of the middle joint.
ClinPediatr (Phila), 2011. If the plantar plate tear is not treated properly, the condition becomes chronic and the deformity can be greater. The mean time from injury to definitive surgical treatment was 8 weeks (range, 2 weeks to 4 months). Volar plate avulsion fractures: •Treated differently to other fractures –have their own protocol •Often associated with a dislocation injury therefore need to assess for other structural damage ie collateral ligaments and adjust treatment accordingly •Protected mobilisation indicated immediately post fracture More specifically, the volar migration of the lateral bands and subsequent attenuation of the triangular ligament causes this deformity (Figure 2). This type of fracture is common but easily missed 2 and, unfortunately, permanent loss of PIP joint function results from mismanagement. She was not able to describe the exact mechanism, as it happened in a “pile-up.” She was seen in… It usually involves injury to the volar plate and may include a volar plate avulsion fracture. Typically, there is swelling of the PIPJ. Patients with injuries to the volar plate will be tender to palpation along the anterior aspect of … For acute injuries, immobilization is the treatment of choice, unless there is an osseous avulsion or laceration, in which case surgery is indicated ( 52 ). Gone are the days when premiums are based on a diverse group … It is located on the palm side of the finger in the metacarpophalangeal and interphalangeal joints where they reinforce the joint capsules and enhance joint stability. Thank you, Brian. Surgical treatment included volar plate advancement arthroplasty and K-wire fixation of the reduced joint for 4 weeks. It prevents the joint bending backwards and consists of a tough plate made from fibro- These injuries can lead to joint subluxation without frank dislocation or true dislocation of the joint. Volar plate injuries occur when the finger is hyperextended eg. Knowledge of the orthopedic Eaton classification is practical when reporting volar plate injury of the PIP joint as it influences the decision on management. Plantar plate tears are very common and now, with the possibility of performing direct repair of the plantar plate both from dorsal and plantar approaches, the podiatric surgeon should completely understand the biomechanics of plantar plate tears to make the best conservative and surgical treatment decisions for their patients. volar plate injury Hyperextension of a finger joint, such as a dorsal dislocation, can injure the volar plate ( Figure 8 ) . 3 The ligament arises at the dorsal ulnar aspect of the metacarpal head with the center of the origin volar to the dorsal cortex by approximately a third of the AP dimension of the metacarpal head and 3 to 5 mm proximal to the articular surface. Injury to the volar plate can occur when the joint is hyperextended. Diagnosis of a volar plate injury is based on history and clinical examination. Tang, Pediatric foot fractures: evaluation and treatment. ... A third indication for open reduction is an untreated chronic volar plate avulsion that allows the joint to hyperextend. Flexor tendon rupture after volar plating of the distal part of the radius is an infrequent but serious complication. A volar plate injury is commonly called a jammed finger or sprain. It is commonly injured through hyperextension, for example a ball hitting the fingertip. B, Volar PIPJ fracture-dislocation. Note that the volar plate (VP) attachment is involved in the fracture. An acute dislocation is rarely subtle, but when patients present with chronic instability symptoms, there may be guarding against full joint extension and soft tissue thickening in areas of chronic pathology. Failure to recognize this injury can have potentially devastating consequences due to the imbalance of flexor and extensor forces which will lead to a boutonniere deformity (Figure 1). "Tibial tubercle fractures are most common in adolescent males after violent contraction of the quadriceps mechanism, typically in an athletic setting.
