Tarsal Tunnel Syndrome: Outcome According to Etiology.

Surgical results in tarsal tunnel syndrome are variable, and etiology seems to be a factor. Three possible etiologies can be distinguished. The aim of the present study was to compare surgical results according to etiology.

Predictive factors of effective tibial nerve release in tarsal tunnel syndrome.

Background: Factors that may affect surgical decompression results in tarsal tunnel syndrome are not known.

Methods: A retrospective single-center study included patients who had undergone surgical tibial nerve release. The effectiveness of decompression was evaluated according to whether the patient would or would not be willing to undergo another surgical procedure in similar preoperative circumstances.

Can the axial cross-sectional area of the tibial nerve be used to diagnose tarsal tunnel syndrome? An ultrasonography study.

Introduction: The axial cross-sectional area (CSA) of the tibial nerve can be measured with ultrasonography. In patients who have posteromedial tarsal tunnel syndrome (TTS), there is little information on the nerve's CSA even though this information could be useful for determining whether the nerve is damaged. This led us to carry out a case-control study in which the tibial nerve's axial CSA was measured in healthy patients and in patients with TTS.

[Hindfoot pain].

The hindfoot is the part of the foot which is proximal to the midtarsal joint. The obvious causes of pain are not considered (post-traumatic etiologies, sprains and fractures but also cutaneous lesions). The main etiologies on the subject are successively exposed by following the localization of the pain.

[Rheumatoid arthritis: a general disease and local diseases].

The rheumatoid synovitis affects the joints by destroying the cartilage, the sub-chondral bone and the articular capsule. The tendons and ligaments can be degraded by proximity or by the means of the affected synovial sheaths. This conjunction of effects involves a foreseeable degradation on the complex articulations whose clinician must know the stages to interfere effectively into a preventive way by local interventions when the general treatments of the disease are insufficient and before recourse to the repairing surgery.

Posterior tibial tendon and subtalar joint complex in rheumatoid arthritis: magnetic resonance imaging study.

Objective: To observe by magnetic resonance imaging (MRI) the pathologic changes in the posterior tibial tendon (PTT), subtalar joint complex (STJC), and sinus tarsi in patients with rheumatoid arthritis (RA), and if possible to determine their involvement in the course of the disease.

Methods: Sixty-seven rheumatoid feet with mid and hindfoot pain underwent MRI with gadolinium injection. Localized enhancement and anatomic lesions were assessed in the 3 sites.

Rheumatoid flat foot and deformity of the first ray.

Objective: To study the relationship between flat foot and forefoot deformities in rheumatoid arthritis (RA) in order to improve understanding of the progression of deformity and thus provide more appropriate treatment.

Methods: Anteroposterior and lateral weight-bearing radiographs were obtained of 308 feet of patients with RA and 202 feet of patients with neck pain (control feet).

Results: In women with RA, we observed with disease duration an increased frequency of flat foot that was correlated with first ray deformity (chiefly metatarsus primus adductus) and severe stages of disability.
