Injuries to the Midtarsal Joint and Lesser Tarsal Bones

Results and complications of operative and non-operative navicular fracture treatment

“…However, secondary osteoarthritis is a possible complication [41]. Furthermore, potential more serious injuries, such as a midtarsal subluxation and instability, should be taken into account [22,26,42,43]. Taking the good (24/36, 67%) results of avulsion fractures into account, the authors agree that most often non-operative treatment should be recommended.…”

“…Furthermore, associated injuries and injury mechanism influence the development of secondary osteoarthrosis. The risk to develop a non-union or osteonecrosis of the navicular bone has been described [14,17,21,22,44,53]. The poorly vascularized central zone of the navicular body [54] predisposes the bone to healing disturbance after severe fracture.…”

“…Non-operative treatment should be performed if articular displacement is less than 2 mm, no evident subluxation, and the MCF is intact [3,17,21,22]. Treatment of choice is immobilization in a short leg cast with non-weight bearing for 6-8 weeks.…”

Acute plantar midtarsal dislocation with intercuneiform dislocation: Case study, diagnosis and management

“…6 Although more energy is required to cause a dorsal midtarsal dislocation, it is the most often reported direction of dislocation given the frequent mechanism of a dorsally directed force to the forefoot. 7 In contrast, plantar midtarsal dislocations are rare, accounting for only 7% of midtarsal dislocations. 7 We describe the case of a 24-year-old male who sustained a plantar midtarsal dislocation associated with an intercuneiform dislocation, open proximal 5[ 2 6 _ T D $ D I F F ] th metatarsal, and closed midfoot fractures from a blunt force trauma.…”
