Muscles that Move the Leg01:23

Muscles that Move the Leg

2.4K
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

24
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Muscles of the Leg that Move the Foot and Toes01:28

Muscles of the Leg that Move the Foot and Toes

1.9K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....

Summary

A motorcycle accident caused a sciatic nerve injury via proximal hamstring tendon avulsion. This case highlights that such injuries can occur even without a major femur fracture.

Area of Science:

  • Neurology
  • Orthopedic Surgery
  • Traumatology

Background:

  • Sciatic nerve injuries are often associated with direct trauma or fractures.
  • Proximal hamstring tendon avulsions are typically sports-related injuries.

Observation:

  • A 63-year-old male sustained a right sciatic nerve injury after a motorcycle accident.
  • Initial diagnosis was an incomplete distal femur fracture; foot drop was noted post-cast removal.
  • Magnetic resonance imaging revealed a proximal hamstring tendon avulsion.

Findings:

  • The patient presented with a sciatic nerve lesion at the proximal biceps femoris level.
  • Conservative treatment (physiotherapy) and neurosurgical intervention yielded no improvement.
  • The injury mechanism was proximal hamstring tendon avulsion secondary to motorcycle accident trauma.

Implications:

  • This case underscores that proximal hamstring tendon avulsion can lead to sciatic nerve injury.
  • It emphasizes the importance of considering nerve injury in trauma patients, even with seemingly minor fractures.
  • Early and accurate diagnosis of sciatic nerve injury is crucial for appropriate management, even in unusual presentations.
