Background and purpose:
Hamstring injuries are frequent injuries in athletes, with the most common being strains at the musculotendinous junction or within the muscle belly. Conversely, hamstring avulsions are rare and often misdiagnosed leading to delay in appropriate surgical interventions. The purpose of this case report is to describe the hist...

... to high suspicion of a proximal hamstring avul- sion the physical therapist ordered a magnetic res- onance image (MRI) study and consulted with a musculoskeletal radiologist to facilitate a same day study. The physical therapist also consulted with the on call orthopaedic physician assistant and an ortho- paedic surgeon who agreed to see the patient within two days. MRI (Figures 3-5) revealed a complete proxi- mal hamstring avulsion off the ischial tuberosity with 5 cm tendon retraction of the semimembranosus and semitendinosus muscles and 6.5 cm retraction of the biceps femoris. After evaluation by the orthopedic surgeon, the patient was scheduled for surgical inter- vention five days later (13 days following his ...

Ischiofemoral impingement (IFI) is an often unrecognized cause of hip pain caused by abnormal contact between the lesser trochanter

Ischiofemoral impingement (IFI) is a rare cause of hip pain defined by a narrowing of the space between the lateral aspect of the os ischium and the lesser trochanter of the femur. Several underlying anatomic, functional and iatrogenic pathologies have been identified for symptomatic IFI in native hip joints and after total hip arthroplasty. Clinic...
Stress fractures are common injuries associated with repetitive high-impact activities, often in high-level athletes and military recruits. Although predominantly occurring in the lower extremities, stress fractures may occur wherever there is a sudden increase in frequency or intensity of activity, thereby overloading the yield point of the local...

Die Ruptur des proximalen Sehnenursprungs der Ischiocruralmuskulatur (ICM) betrifft ungefähr 10 % aller Verletzungen der ICM. Vor allem Sportler der mittleren Altersklassen sind betroffen. Ein kompletter Abriss aller 3 Sehnen gilt beim aktiven Patienten als Indikation zur operativen Sehnennaht. Die exakte Diagnose wird jedoch häufig nicht sofort gestellt. Dies kann zu bleibenden Beschwerden mit Schmerzen, Muskelschwäche und Neuralgien führen. Die operative Therapie besteht in einer Ankernaht des Sehnenursprungs mit guten klinischen Resultaten in mehreren Fallserien. Die genaue Kenntnis der spezifischen Anatomie ist zur Vermeidung von Komplikationen sehr wichtig, ebenso wie die Einhaltung einer abgestuften Nachbehandlung zur ossären Sehnenanheilung. Hauptziele dieses Beitrags sind die Vermittlung der typischen Anamnese, klinischen Präsentation und Untersuchungstechnik, um die sofortige klinische Diagnose zu ermöglichen, die dann magnetresonanztomographisch gesichert werden sollte.
