of the FCR tendon without a clear description of an accompanying intersection syndrome [14]. Although tendon intersection syndromes theoretically may occur at any site in the human body at which tendons cross each other, most descriptions have emphasized their occurrence in the forearm and wrist, either proximally (between the first (abductor pollicis longus and extensor pollicis brevis) and second (extensor carpi radialis and brevis) extensor tendon compartments) or distally (between the second and third (extensor pollicis longus) extensor tendon compartments) [23–27]. The pathophysiology of tendon intersection syndromes remains unclear [28] but clinical manifestations are believed to be secondary to overuse [29] or mechanical friction related to repetitive flexion and extension of the wrist [25]. The pathophysiology of an intersection syndrome between the tendons of the FCRB and FCR muscles may relate, at least in part, to irritation by adjacent scapho-trapezio- trapezoid osteophytes [26]. Additionally, an accessory FCRB muscle may cause hypoplasia of the PQ muscle when it occupies the radial insertion of the PQ muscle [4, 5] or it may result in compressive neuropathy of the anterior interosseous nerve and downstream muscle denervation when the FCRB muscle is hypertrophied [4, 18, 30, 31]. Furthermore, the FCRB muscle can also be injured during minimally invasive volar- sided fixation of a distal radial fracture [32]. Our case report, in common with others, serves as a reminder that an accessory muscle or its tendon may cause clinical manifesta- tions, including those associated with an in- tersection syndrome.

In the literature, there is no follow-up longer than 1 year for hip dislocation after sporting activities. Hip dislocation during sports is rare but challenging, as it implicates a long rehabilitation time. In addition, serious complications can emerge in case of delayed reduction or imperfect restoration of the joint surfaces, especially in professional athletes. Operative intervention is often required to achieve anatomic reduction and, hopefully, a favorable outcome. In the presented case, surgical treatment led to a congruent joint reconstruction without any postoperative complications. Considering that femoral head necrosis has not occurred at the 12- month follow-up, the risk of this complication is significantly reduced or diminished. Nevertheless in the fore coming years, post- traumatic osteoarthritis may develop leading to activity limitation or even the need for hip joint arthroplasty.
