Is the adductor longus muscle parallel or pennate?

abdominis). In a fusiform muscle, the fibres may be close to parallel in the 'belly', but converge to a tendon at one or both ends. Where fibres are oblique to the line of pull, muscles may be triangular (e.g. temporalis, adductor longus) or pennate (feather -like) in construction. The latter vary in complexity (see

Causes

A Flexor Hallucis Longus tear is rare and the cause of a tear can be a result of trauma, sheer forces, or when a significant amount of force is put through the muscle. A partial tear can occur when landing from a jump or through repetitive motion such as repeatedly going up onto one’s toes.

Diagnosis

Diagnosis of a Flexor Hallucis Longus tear is achieved through an MRI or a cost-effective form of imaging is an ultrasound scan. A clinical test can be carried out of resisting flexion of the big toe. Pain on-resistance is indicative of a positive test. An x-ray is unable to detect a Flexor Hallucis Longus tear.

Symptoms

Symptoms of a Flexor Hallucis Longus tear is a sharp pain with activity while there is rarely pain at rest. There is often a specific incident that relates to the onset of pain. If the injury is acute there may be some swelling and bruising around the area of injury. It can be painful to jump or go onto your toes.

Causes

Flexor Hallucis Longus Tendonitis (Also known as Flexor Hallucis Tendinopathy) is usually caused by a repetitive overload of the tendon. This can result in a pathological change of the tendon making it weaker than it was pre-injury. In the acute stages, there may be pain and swelling along the tendon.

Diagnosis

Diagnosis of Flexor Hallucis Longus Tendonitis can be achieved clinically by a Physical Therapist or they may refer for an MRI to correlate with their clinical assessment.

Treatment

Symptoms are often worse with activities such as running, jumping, and bending the big toe. There may be some stiffness on the tendon first thing in the morning that eases after 30-60 minutes. In less acute episodes it can be pain-free to exercise but the pain becomes more prominent afterward.
