Introduction The hamstring muscles are frequently implicated in posterior thigh pain due to strains. The hamstring muscles are the three most superficial muscles that span the posterior thigh, and consist of the biceps femoris, semitendinosus, and semimembranosus. The long head of biceps femoris originates from the inferiomedial aspect of the ischial tuberosity and inserts into the head of the ...

We present a case of avulsion of a large fragment of the ischial tuberosity in an elderly lady, caused by an extreme abduction of the hip. To our knowledge such an injury has not yet been described in the elderly. The decision to operate was based on the reported experience with this injury in young individuals. We assumed that the same indications applied, while also taking into account the kn...

Purpose: The ischial tuberosity, referred to as the “sit bone” by patients with pain when sitting, is surrounded by critical nerves. Depending upon how a person places weight on the ischial tuberosity, symptoms can vary from pudendal nerve symptoms, to sciatica, or to posterior femoral cutaneous nerve (PFCN) symptoms. This research relates, for the first time, the involvement of the PFCN, inclu...

Sitting for prolonged periods of time increases seating interface pressures, which is known to increase the risk of developing pressure ulcers. Those at risk of developing pressure ulcers are advised to perform pressure relieving movements such as "pushups" or "forward leans" in order to reduce the duration and magnitude of pressure acting on the vulnerable ischial tuberosity region. The aim of...

There is a paucity of orthopaedic literature describing avulsion of the ischial tuberosity, but its spontaneous healing does not seem to have been reported to-date. This article describes the case of a young football player who suffered an avulsion fracture of the ischial tuberosity while kicking vigorously next to the ball during a football match. The diagnosis was not made at the time of trau...

BACKGROUND Blockade of the sciatic nerve is necessary for complete analgesia of the lower extremity using peripheral nerve blocks. We identified the sciatic nerve in relation to the ischial tuberosity in fresh cadaver dissections as well as in patients to compare sciatic nerve blockade using the conventional approach versus our experimental approach. Specifically, we tested the hypothesis that ...

T he term ‘‘snapping bottom’’ was initially used by Rask to describe subluxation of the long head of the biceps femoris tendon at the ischial tuberosity, in what we believe to be the only reported case of this phenomenon in the literature. This entity was discovered by reproduction of the snapping during active hip flexion and with direct palpation of the snapping long head of the biceps femori...
