UNASSIGNED: Management of ankle pain in dancers can be challenging because of the repetitive stress and complex demands placed on this region. Despite the prevalence of ankle injuries in this population, literature on surgical outcomes and return to dance is limited.
UNASSIGNED: To retrospectively evaluate the efficacy and functional outcomes after surgical excision of a symptomatic os trigonum in dancers.
UNASSIGNED: Case series; Level of evidence, 4.
UNASSIGNED: Between June 2006 and June 2016, a total of 44 dancers underwent surgical excision of a symptomatic os trigonum at a single institution and by a single surgeon. All patients presented with symptoms of posterior ankle impingement syndrome and subsequently failed nonsurgical treatment. Clinical analysis was conducted using various pre- and postoperative patient-reported outcome questionnaires, including the Veterans RAND 12-Item Health Survey (VR-12), Foot Function Index-Revised (FFI-R), and visual analog scale (VAS) for pain, as well as subjective patient satisfaction.
UNASSIGNED: A total of 44 patients (54 ankles; mean age, 18.2 years) were retrospectively evaluated at a mean follow-up of 33.4 months. The VR-12 Physical Health score improved from a mean score of 37.8 ± 11.9 to 51.2 ± 10.5 (P < .001). The cumulative FFI-R score improved from 46.45 ± 13.8 to 31.2 ± 9.7 (P = .044), with the subcategory of \"activity limitation\" representing the highest-scoring FFI-R subcategory at 65.28 ± 13.4 preoperatively and improving to 34.47 ± 12.4 at follow-up (P < .001). The mean VAS score for subjective pain improved significantly from 5.39 ± 2.84 to 1.73 ± 2.10 (P < .00044).
UNASSIGNED: Overall, the findings of the present study demonstrate that dancers of varying style and level improved significantly according to various clinical measures. Patients included in this study reported that they returned to their previous level of dance upon completion of physical therapy and maintained thriving postoperative careers, which for several meant dancing at the professional level.

Posterior ankle impingement is a cause of posterior ankle pain common in those who perform frequent plantarflexion activities. Three young patients presented with posterior ankle pain which was initially attributed to peroneal tendon subluxation. However, detailed physical exam and imaging confirmed the diagnosis of posterior ankle impingement as the actual cause of pain. The peroneal tendon subluxation was not causal but an unrelated co-incidental finding. After failed prolonged conservative management (rest, immobilization and physical therapy), the patients underwent posterior ankle arthroscopic debridement for the impingement resulting in return to prior sporting activity without limitation and no recurrence of pain at 19 months follow-up. Posterior ankle impingement diagnosis could be masked by co-incidental asymptomatic peroneal tendon subluxation in pediatric patients.

BACKGROUND: Os trigonum syndrome is a relatively uncommon condition, resulting from compression of a congenital bony anomaly (os trigonum) and adjacent soft tissues during repetitive hyper-plantarflexion. This condition is currently well-described in ballet, soccer, and running athletes, but few cases exist describing os trigonum syndrome in overhead athletes.
METHODS: A 22-year-old national level male javelin athlete presented with a recalcitrant history of posterior ankle pain following a hyper-plantarflexion mechanism. Imaging demonstrated a symptomatic os trigonum and inflammation of surrounding soft tissues. Re-aggravation following a conservative trial of care led to orthopaedic referral. Surgical excision of the os trigonum was performed with an open posterolateral approach. The athlete returned to competition three months later with no recurrence of symptoms.
CONCLUSIONS: This case discusses the clinical presentation, imaging, and management of a symptomatic os trigonum and related pathologies in a javelin thrower.
BACKGROUND: Le syndrome de l’os trigone est une pathologie relativement peu fréquente causée par la compression d’une anomalie osseuse congénitale (os trigone) et des tissus mous adjacents durant les mouvements répétitifs en hyperflexion plantaire. Cette pathologie touche souvent les danseuses de ballet, les joueurs de soccer et les coureurs. Peu de cas sont enregistrés chez les athlètes pratiquant des sports comportant des mouvements au-dessus de la tête.
UNASSIGNED: Un lanceur de javelot de 22 ans se plaignait d’une douleur postérieure de la cheville déclenchée par des mouvements répétitifs en hyperflexion plantaire. Les examens par imagerie montraient un os trigone symptomatique et une inflammation des tissus périphériques. Une aggravation après une tentative de traitement conservateur a mené à une demande d’une consultation en orthopédie. L’excision chirurgicale de l’os trigone a été réalisée à ciel ouvert par voie d’abord ouverte postérolatérale. L’athlète e repris la compétition au bout de trois mois; ses symptômes ne sont pas réapparus.
UNASSIGNED: Cette étude de cas présente le tableau clinique, les examens par imagerie et la prise en charge d’un os trigone symptomatique et des pathologies apparentées observés chez un lanceur de javelot.

OBJECTIVE: To describe a clinical treatment algorithm for posterior ankle impingement (PAI) syndrome in professional football players.
METHODS: A case series of 26 elite professional football players diagnosed and treated for posterior ankle impingement syndrome were included for the study. All of the athletes received conservative treatment with physical therapy modalities initially. If the first line medical treatment and rehabilitation was ineffective to alleviate the symptoms, ultrasound-guided corticosteroid injection was proposed and thereafter the patients underwent posterior ankle arthroscopy if the complaints are still unresolved. The pain scores (AOFAS, VAS), and time to return to play were the main outcome measures.
RESULTS: The complaints of 18 (69.2%) players were subsided with non-surgical treatment whereas three of acute cases and five of the chronic cases did not respond to medical treatment and arthroscopic surgery was performed for eight athletes. Eighteen players returned to training for a mean time of 36.3 days (24-42 days) after conservative treatment. The patients who underwent arthroscopic surgery returned to training for a mean time of 49.8 days (42-56 days) after the surgery. All athletes returned to their previous level of competition after treatment without any complications or recurrence in a mean follow-up 36.5 months (19-77 months).
CONCLUSIONS: Non-surgical treatment modalities were effective in 2/3 of posterior ankle impingement syndrome in elite football players. On the other hand, posterior ankle arthroscopy is safe and effective treatment option for posterior ankle impingement syndrome if the conservative treatment fails.
METHODS: Level IV, Therapeutic study.

We describe a rare case of a fracture of the medial tubercle of the posterior process of the talus in a 16-year-old male athlete who fell during basketball practice. The patient presented to our orthopedic clinic when pain and swelling had persisted despite 2 weeks of anti-inflammatory medication and rest. Computed tomography and magnetic resonance imaging scans revealed a fracture of the posteromedial tubercle of the talus and a small amount of retained fluid in the joint. Immobilization with a below-the-knee cast and non-weightbearing for 4 weeks, with a gradual return to full activity, was successful. At the 1-year follow-up evaluation, the patient expressed no complaints. Fracture of the posteromedial tubercle of the talus will usually result in a misdiagnosis or delayed diagnosis owing to the insidious onset of symptoms. We believe the present fracture configuration resulted from the vertical compression force that occurred on landing by posterior medial ankle impingement in plantarflexion-supination, modifying the conventional concept of the posteromedial tubercle fracture. We also present a suggested classification with a flowchart diagram.

Accessory ossicles are widely prevalent in the ankle and foot. Although they are often asymptomatic, they can present clinically with symptoms at times. When they occur bilaterally in a patient who presents with unilateral complaints, it is clinically difficult to attribute the symptoms to the presence of these common anatomic variants. One needs specific imaging to assess the clinical relevance of the accessory ossicles, in order to tailor the treatment plan. The case presented in this article is one such example, where the patient presented with chronic unilateral ankle pain and initial radiographs revealed bilateral os trigonum and os subtibiale. He underwent a technetium-99m methyl diphosphonate (Tc-99m MDP) bone scan and single photon emission computed tomography/computed tomography (SPECT/CT). The Tc-99m MDP scan showed a focal uptake in the ankle of concern. SPECT/CT complemented the finding by exactly localizing the uptake to the posterior subtalar joint and around the os trigonum, thereby pointing to the diagnosis of os trigonum syndrome.
