Martin Jordan, Manfred Thomas, Wolfgang Fischer
With the current data concentrating on different operative treatment options for plantar plate tears, few data can be found on possible nonoperative treatment strategies for this entity and the specifics of such treatment. In the present case report, the successful nonoperative treatment of a patient with a rupture of the plantar plate in a lesser toe metatarsophalangeal joint is presented. The patient was followed up using repeat clinical examinations and high-resolution magnetic resonance imaging scans for 1 year after the imitation of therapy to provide information on the different stages of the healing process...

The development of gangrene after elective digital surgery is a rare complication. We present a case of a patient with normal preoperative vascular examination findings and a history significant for untreated hepatitis C. The patient underwent revisional second toe arthrodesis and plantar plate repair with pin fixation. After surgery, she developed gangrene and ultimately required partial digital amputation. The wound at the amputation site worsened postoperatively, warranting a rheumatologic evaluation that revealed previously undiagnosed cryoglobulinemia...

Dislocation of multiple metatarsophalangeal joint is an uncommon injury. The mechanism of injury is a high energy force distal to proximal with foot in hyperextension at the metatarsophalangeal (MTP) joint. The acute hyperextension of the toe at the moment of injury causes avulsion of the plantar part of the capsule from the junction of head and neck of the metatarsal. If the collateral ligaments remain intact, they maintain the locked fibrocartilaginous plate over the dorsum of the head of the metatarsal, making closed reduction impossible...

BACKGROUND: Access to the plantar plate has been described using either a plantar approach or an extensive dorsal approach that required complete joint destabilization and often a metatarsal osteotomy. Clinical scenarios related to plantar plate tear vary and the pathologies in early stages are frequently limited to unilateral soft tissue structures; a less invasive operative approach may be possible. A novel approach requiring a release of only the lateral collateral ligament and the lateral half of the plantar plate is presented in this cadaver model; the extent of joint exposure possible is described...

The tarso-metatarsal 1 joint (TMT-I) arthrodesis is a treatment option or moderate to severe hallux valgus (HV) deformities. Instability of the TMT1 joint is still a debatable indication. Using stable osteosynthesis techniques allows early postoperative weight bearing. Plantar plating combined with a lag screw is the biomechanical most stable construct. An additional intermetatarsal screw can improve the horizontal stability. Clinical results are good and radiological parameters stay constant, even in the long term...

Proximal fifth metatarsal fractures, zones II and III, are commonly treated surgically, especially in elite athletes. Intramedullary screw fixation remains the most used construct despite nonunion and refracture. High tensile forces on the plantar-lateral aspect of the fifth metatarsal are difficult to control, and intramedullary screw fixation depends on ideal screw position, length, and width. The authors present a plantar plating technique with cancellous bone autograft for zones II and III proximal fifth metatarsal fractures...

BACKGROUND: For internal fixation of AO classification Type B lateral malleolar fracture, insertion of lag screws into the fracture plane and fixation with a one-third tubular plate as a neutralization plate are the standard treatment procedures. The one-third tubular plate is processed to a hook shape and hung on the distal end of the fibula. In this study, to compare the function of the hook and lag screws of a one-third tubular plate and LCP for osteosynthesis of lateral malleolar fracture, mechanical indices of internal fixation were compared among the one-third tubular plates with lag screws with and without the hook and a locking compression plate...

Calcaneal fractures are the most common fractures of the tarsal bones. The stability of fixation is an important factor for successful reconstruction of calcaneal fractures. The purpose of this study was to analyze the biomechanical influence of plate fixation with different combinations of locking and nonlocking screws during early weight-bearing phase. A three-dimensional FE foot model was established using ANSYS software, which comprised bones, cartilages, plantar fascia, and soft tissue. Calcaneal plate was fixed with whole locking (WLS), whole nonlocking (WNS), and hybrid screw configurations for FE analysis...

BACKGROUND: Arthrodesis of the medial column (navicular, cuneiform I and metatarsal I) is performed for reasons such as Charcot arthropathy, arthritis, posttraumatic reconstruction or severe pes planus. However, the complication rate is still high and mainly resulting from inadequate fixation. Special plates, designed for medial column arthrodesis, seem to offer potential to reduce the complication rate. The aim of this study was to investigate biomechanically plantar and dorsomedial fusion of the medial column using two new plating systems...

BACKGROUND: Metatarsophalangeal joint instability of the lesser toe can cause acquired toe deformity. Plantar plate deficiency is the major pathology. Plantar plate repair can stabilize the joint but may result in iatrogenic transverse plane toe deformity in correction of claw toe deformity. Limited toe extension can be resulted after correction of crossover toe deformity by plantar plate tenodesis and extensor digitorum brevis transfer. A modification of the technique is proposed. MATERIALS AND METHODS: The clinical outcomes of 10 patients with the modified procedure performed were assessed...
