An Achilles sleeve avulsion occurs when the tendon ruptures distally from its calcaneal insertion as a continuous "sleeve." This relatively rare injury pattern may not be appreciated until the time of surgery and can be challenging to treat because, unlike a midsubstance rupture, insufficient tendon remains on the calcaneus to allow for end-to-end repair, and unlike a tuberosity avulsion fracture, any bony element avulsed with the tendon is inadequate for internal fixation. This study aimed to highlight the characteristics of Achilles sleeve avulsions and present the outcomes of operative repair using suture anchor fixation. ⋯ Level IV, retrospective case series.

Open reduction and internal fixation (ORIF), the standard treatment for unstable ankle fractures, has well-known wound complications. Minimally invasive surgery (MIS) has been proposed to decrease these complications. The objectives of this study were to describe an algorithm of MIS for fibular plating and compare the radiographic restoration of fibular anatomy, functional outcomes, and complications between ORIF and MIS for ankle fractures. ⋯ Level III, retrospective comparative study.

Rotational Dynamics of the Normal Distal Tibiofibular Joint With Weight-Bearing Computed Tomography.
The normal distal tibiofibular joint is strongly stabilized by the syndesmosis, where previous cadaveric, biomechanical studies demonstrated only minimal widening and posterior translation of the fibula in external rotation of the ankle. However, little is known about normal rotational dynamics of the distal tibiofibular joint in upright weight-bearing conditions. The purpose of this study was to investigate the normal anatomy and rotational dynamics of the distal tibiofibular joint under physiological conditions on weight-bearing cone beam computed tomography (WBCT). ⋯ The current study provides the reference values to evaluate the rotational dynamics of a normal distal tibiofibular joint.

Concomitant tears of the peroneus longus and brevis tendons are rare injuries, with literature limited to case reports and small patient series. Only 1 recent study directly compared the results of single-stage lateral deep flexor transfer, and no previous series objectively evaluated power and balance following transfer. The purpose of this study was to evaluate clinical outcomes, patient satisfaction, and objective power and balance data following single-stage flexor hallucis longus (FHL) and flexor digitorum longus (FDL) tendon transfers for treatment of concomitant peroneus longus and brevis tears. ⋯ Level IV, retrospective case series.
