Insights

Hip dislocation is a rare complication of femoral lengthening for congenital short femur. Excessive lengthening may cause progressive acetabular dysplasia, necessitating complex surgical intervention.

Area of Science:

  • Orthopedic Surgery
  • Pediatric Orthopedics
  • Biomechanical Engineering

Background:

  • Congenital short femur presents significant challenges in limb length discrepancy.
  • Femoral lengthening is a common treatment, but complications require careful management.
  • Hip dislocation is a rare but serious complication associated with femoral lengthening procedures.

Purpose of the Study:

  • To report hip dislocations occurring during femoral lengthening in congenital short femur.
  • To analyze contributing factors and discuss treatment strategies for this complication.
  • To evaluate outcomes following surgical management of post-lengthening hip dislocations.

Main Methods:

  • Retrospective case series of three patients experiencing hip dislocation during femoral lengthening.
  • Analysis of radiographic parameters including acetabular dysplasia and center edge angle.
  • Description of surgical interventions, including soft tissue release, open reduction, femoral shortening, and acetabular procedures.

Main Results:

  • An average lengthening of 9 cm was achieved prior to dislocation.
  • Progressive acetabular dysplasia and decreasing center edge angle were observed.
  • Closed reduction was unsuccessful; surgical treatment yielded good outcomes in two of three patients at 4.4 years follow-up.

Conclusions:

  • Excessive femoral lengthening can lead to hip dislocation due to acetabular dysplasia.
  • Complex surgical management is often required for hip dislocations post-femoral lengthening.
  • Avoiding excessive lengthening is crucial to prevent this complication in congenital short femur treatment.

Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

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 neck...
Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
Knee Joint01:23

Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...
Muscles that Move the Thigh01:20

Muscles that Move the Thigh

The thigh's motion is primarily governed by muscles originating in the pelvic girdle and inserted into the femur. One crucial muscle, the iliopsoas, is a combination of the psoas major and the iliacus muscles, sharing a common insertion point on the lesser trochanter of the femur.
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar fascia...
