A volar plate injury is commonly called a jammed finger or sprain. Volar plate injuries occur when the finger is hyperextended eg. There may be a small piece of bone avulsed (pulled away) from the middle phalanx when this occurs. Typically, there is swelling of the PIPJ. If the plantar plate tear is not treated properly, the condition becomes chronic and the deformity can be greater. The distal metaphysis, which anchors the complex nail matrix and nail plate, is often affected by distal fractures. Injury to the volar plate can occur when the joint is hyperextended. volar plate injury Hyperextension of a finger joint, such as a dorsal dislocation, can injure the volar plate ( Figure 8 ) . It is commonly injured through hyperextension, for example a ball hitting the fingertip. If a complete tear occurs, the ligament usually ruptures or tears from its attachment on the middle phalanx. 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). Maximal tenderness on palpation is over the volar PIPJ and the patients may report pain on passive hyperextension of the PIPJ. It is initiated by wear debris from prosthetic implants.

Note that the volar plate (VP) attachment is involved in the fracture. 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. Am Fam Physician, 2003. 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.

Read more » Bruising to the volar surface of the PIPJ is sometimes observed. "Tibial tubercle fractures are most common in adolescent males after violent contraction of the quadriceps mechanism, typically in an athletic setting. Patients with injuries to the volar plate will be tender to palpation along the anterior aspect of … The middle phalanx (P2) is dislocated or subluxated volarly and the dorsal lip is fractured. Surgical treatment included volar plate advancement arthroplasty and K-wire fixation of the reduced joint for 4 weeks. It is also referred to as predislocation syndrome, crossover toe deformity and floating toe syndrome. This happens when the finger is bent backward too far (hyperextended). 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. 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. This is located in the ball of your foot or the metatarsalgia region. Volar plate avulsion fracture (Figure 7) occurs after hyperextension injury to the PIP joint, often from a ‘jamming’ injury during ball sports. More specifically, the volar migration of the lateral bands and subsequent attenuation of the triangular ligament causes this deformity (Figure 2). Avulsion of the nail plate and injury to the nail bed is often associated with tuft fractures. This type of fracture is common but easily missed 2 and, unfortunately, permanent loss of PIP joint function results from mismanagement. C, Pilon injury to the PIPJ.

The volar plate is a ligament located at the middle knuckle (proximal interphalangeal joint - PIPJ) of the finger. The mean time from injury to definitive surgical treatment was 8 weeks (range, 2 weeks to 4 months). As the deformity progresses, the cartilage in the joint capsule can become eroded, leading to arthritis and increased pain. B, Volar PIPJ fracture-dislocation.

Clinical History: A 16 year-old male presents for MRI of the hand following a wrestling injury. Volar plate sprain or partial tear occurs after a hyperextension injury of the finger. Severe collateral ligament injury is uncommon in conjunction with volar plate instability but must be recognized and treated where indicated. The ligament can pull off by itself or with a piece of bone called and avulsion fracture. The Volar Plate is a thick ligament which joins together two bones in the finger and prevents hyperextension. gressive attenuation of the volar plate.Late-stagesecondarydeformi-ty includes a zigzag collapse pattern (Figure 6).

Periprosthetic osteolysis is a common mode of total hip arthroplasty failure. commonly seen with small avulsion fracture of the base of the middle phalanx; simple . These injuries can also lead to a fracture (break) called an avulsion fracture. Flexor tendon rupture after volar plating of the distal part of the radius is an infrequent but serious complication.
