Background: Talar body and neck nonunions and malunions may undergo a reconstructive surgery when joint cartilage is still viable, and no talar collapse or infection has occurred. This is a rare condition and the studies supporting the procedure have small number of cases. The objective of the present study is to report a case series of six patients who underwent talar reconstructions. Materials and Methods: Six patients with talar malunions or nonunions who underwent surgical treatment were reviewed in this retrospective study...

In upright stance, light touch of a space-stationary touch reference reduces spontaneous sway. Moving the reference evokes sway responses which exhibit non-linear behavior that has been attributed to sensory reweighting. Reweighting refers to a change in the relative contribution of sensory cues signaling body sway in space and light touch cues signaling finger position with respect to the body. Here we test the hypothesis that the sensory fusion process involves a transformation of light touch signals into the same reference frame as other sensory inputs encoding body sway in space, or vice versa...

Ankle arthrodesis has been widely reported as an effective solution in treating tibiotalar joint osteoarthritis. The arthroscopic tibiotalar approach for arthrodesis has also been proven to give excellent results in terms of bone fusion rates and reduction of wound-related pain and complications. Historically, ankle malalignment has represented one of the main contraindications for the arthroscopic procedure, but interestingly some investigators have shown that the coronal joint deformity may be addressed arthroscopically as well...

Bone grafting is a common procedure in foot and ankle surgery. Because autogenous graft use results in comorbidity to the patient, the search has been ongoing for the ideal substitute. A novel processing technique for allograft using bone marrow, which retains many of the growth factors, has shown promise in the spinal data and early reports of foot and ankle surgery. We performed a retrospective, comparative study of patients undergoing hindfoot and ankle arthrodesis, with a total of 68 patients included. Of the 68 patients, 29 (42...

Reliable evaluation of osseous consolidation after pedal arthrodesis can be difficult, and the presence or absence of radiographic healing often dictates care. Plain radiographs remain the mainstay imaging tool owing to their cost, efficiency, and low radiation exposure. Applying radiographic parameters that can reliably determine osseous healing is essential. However, currently, no reliable or validated measures are available to determine osseous union of any joint in the foot or ankle. The purpose of the present study was to develop a radiographic healing scoring system that would enhance the diagnostic healing assessment after joint arthrodesis of the foot or ankle...

Posterior tibial tendon dysfunction (PTTD) is a common pathology of the foot and ankle. Numerous techniques are available to reconstruct the flatfoot. Fusions and tendon transfers are popular methods; however, a wide range of complications have been associated with these procedures. The objective of the present study was to demonstrate the outcomes of reconstructive surgery for flatfoot correction without tendon transfer or arthrodesis. We performed a retrospective study of 43 patients and 56 feet who had undergone flatfoot reconstructive surgery from November 2011 to June 2016, with a mean follow-up period of 60 weeks (range 12 to 60 months)...

REVIEW
Pierre-Louis Docquier, Pierre Maldaque, Maryse Bouchard
Tarsal coalition is due to failure of segmentation between two or more foot bones during embryological development at a site where the joint cleft fails to develop. Depending on the nature of the tissue connecting the bones, the abnormality is a syndesmosis, synchondrosis, or synostosis. Although the coalition exists at birth, synostosis usually develops only late during growth. Talo-calcaneal and calcaneo-navicular coalitions account for over 90% of all cases of tarsal coalition. The joint at the site of the coalition is stiff...
