Adult acquired flatfoot deformity is a degenerative disease causing medial arch dysfunction. Surgical correction has typically involved tendon reconstruction with calcaneal osteotomy; however, the postoperative changes have not been fully characterized. The present study assessed the success of surgical correction of Stage IIb adult acquired flatfoot deformity through changes in plantar pressures and patient-generated outcome scores. ⋯ The increased questionnaire scores indicated that surgical correction improved the self-perceived health of the participants. Lateral shifts in the peak pressure and normalized force suggest that forefoot and midfoot loading is altered postoperatively, consistent with the goal of offloading the dysfunctional arch. Thus, the present study has demonstrated that surgical treatment of adult acquired flatfoot deformity can be accurately assessed using patient-reported outcome measures and plantar pressures.

Trans-syndesmotic screws are commonly used to repair syndesmosis ruptures and stabilize the ankle joint. Just as with any surgery, the neurovascular structures can be compromised, causing complications. We evaluated the position of the perforating branch of the peroneal artery to define the risk of arterial compromise during placement of 2 trans-syndesmotic screws. ⋯ A greater percentage of male specimens displayed close proximity between the artery and the superior screw, and the distance of the artery from the distal fibula was statistically significant compared with the distance in the female specimens. Regression analysis revealed that the greater the tibial length, the closer the superior screw was to the artery, with a negative correlation discovered for the inferior screw. We concluded that superior screw placement increased the risk of injuring the perforating branch of the peroneal artery injury, and the likelihood of injuring the artery with the inferior screw increased as the length of the tibia decreased.
