Objective: To assess, utilizing MRI, tarsal tunnel disease in patients with talocalcaneal coalitions. To the best of our knowledge, this has only anecdotally been described before.
Materials And Methods: Sixty-seven ankle MRIs with talocalcaneal coalition were retrospectively reviewed for disease of tendons and nerves of the tarsal tunnel. Interobserver variability in diagnosing tendon disease was performed in 30 of the 67 cases. Tarsal tunnel nerves were also evaluated in a control group of 20 consecutive ankle MRIs.
Results: Entrapment of the flexor hallucis longus tendon (FHL) by osseous excrescences was seen in 14 of 67 cases (21 %). Attenuation, split tearing, tenosynovitis, or tendinosis of the FHL was present in 26 cases (39 %). Attenuation or tenosynovitis was seen in the flexor digitorum longus tendon (FDL) in 18 cases (27 %). Tenosynovitis or split tearing of the posterior tibial tendon (PT) was present in nine cases (13 %). Interobserver variability ranged from 100 % to slight depending on the tendon and type of disease. Intense increased signal and caliber of the medial plantar nerve (MPN), indicative of neuritis, was seen in 6 of the 67 cases (9 %). Mildly increased T2 signal of the MPN was seen in 15 (22 %) and in 14 (70 %) of the control group.
Conclusions: Talocalcaneal coalitions may be associated with tarsal tunnel soft tissue abnormalities affecting, in decreasing order, the FHL, FDL, and PT tendons, as well as the MPN. This information should be provided to the referring physician in order to guide treatment and improve post-surgical outcome.

Anterior tarsal tunnel syndrome, an infrequent entrapment neuropathy involving the deep peroneal nerve beneath the inferior extensor retinaculum in the anterior ankle, is often overlooked on medical images, leading to delayed diagnosis and treatment. We present the case of a 52-year-old male, an avid runner, who exhibited a sensation of burning and tingling in the dorsal region of both feet. Electrophysiologic studies suggested bilateral deep peroneal neuropathy.

The high physiologic demands of sports create dynamic stress on joints, soft tissues, and nerves which may lead to injuries in the athlete. Electrodiagnostic (EDx) assessment is essential to identify the correct diagnosis, localization, and prognosis, to guide management of sports-related neuropathies. A comprehensive review was performed to provide the EDx medical consultant with a practical approach to the common peripheral nerve disorders seen in athletes.

Objective: To compare the stability, ultimate strength, and isometry of 4 prosthetic ligament repairs for canine tarsal medial collateral ligament injury.
Methods: 24 cadaveric canine distal hind limbs with induced medial tarsal instability were randomly divided into 4 groups. Simulated medial shearing injury of the collateral and medial malleolus were repaired using 1 of 4 isometric suture techniques: bone tunnels with nylon suture (TN), ultrahigh-molecular-weight polyethylene (UHMWPE) suture (TU), tibial bone anchor with nylon suture (AN), or talar bone anchor with UHMWPE suture (AU).

Background/objectives: The tibial nerve, commonly misnamed the "posterior tibial nerve", branches into four key nerves: the medial plantar, lateral plantar, inferior calcaneal (Baxter's nerve), and medial calcaneal branches. These nerves are integral to both the sensory and motor functions of the foot. Approximately 15% of adults with foot issues experience heel pain, frequently stemming from neural origins, such as tarsal tunnel syndrome (TTS).
