Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

2.0K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Area of Science:

  • Medical Case Studies
  • Congenital Abnormalities
  • Pediatric Surgery

Background:

  • Polymelia, or accessory limb, is a rare congenital abnormality with an unknown etiology.
  • Accessory limbs can present unique diagnostic and management challenges in infants.

Purpose of the Study:

  • To report a rare case of polymelia in an infant.
  • To review diagnostic and therapeutic considerations for accessory limbs.
  • To highlight management challenges associated with polymelia.

Main Methods:

  • Case presentation of a 2-month-old male infant with an accessory limb.
  • Diagnostic workup including assessment for spinal dysraphism and hip dislocation.
  • Surgical removal of the accessory limb and treatment of associated hip dislocation.

Main Results:

  • The accessory limb was sensate with mobile joints.
  • No associated spinal dysraphism was detected.
  • A left dislocated hip was identified and successfully treated with open reduction.

Conclusions:

  • This study presents a rare case of accessory limb in an infant.
  • Effective surgical management is crucial for both the accessory limb and associated anomalies like hip dislocation.
  • Early diagnosis and intervention lead to favorable outcomes in polymelia cases.
