Summary
Thoracic disk herniation and heterotopic ossification can complicate total hip arthroplasty, leading to recurrent dislocations. Neurologic evaluation is crucial for diagnosing occult spinal lesions causing hip instability.
Area of Science:
- Orthopedic Surgery
- Neurology
- Radiology
Background:
- Recurrent dislocation of total hip prostheses presents a significant challenge in orthopedic surgery.
- Heterotopic ossification is a known complication following hip arthroplasty, potentially leading to joint stiffness and instability.
Observation:
- A patient presented with recurrent dislocation of a total hip prosthesis, concurrent with thoracic disk herniation and heterotopic ossification.
- The recurrent dislocations were attributed to spasticity originating from an undiagnosed spinal lesion.
Findings:
- The study highlights a complex case where spinal pathology (thoracic disk herniation) induced spasticity, leading to hip prosthesis dislocation.
- Technical hip-focused treatments were insufficient without addressing the underlying neurologic cause.
Implications:
- Thorough neurologic examination is essential during the evaluation for total hip arthroplasty to identify potential occult spinal lesions.
- Spasticity from spinal lesions should be considered in cases of recurrent hip dislocation post-arthroplasty.
- Surgical intervention for calcified thoracic disks requires careful consideration due to potential complications.

01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
01:27Degenerative Disc Disease I: Introduction
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...
01:23Degenerative Disc Disease ll: Pathophysiology
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
01:25Hiatal Hernia
A hiatal hernia is the abnormal protrusion of the stomach or other abdominal organs through the esophageal hiatus of the diaphragm into the thoracic cavity.Normally, the gastroesophageal junction (GEJ) lies below the diaphragm and is supported by the phrenoesophageal membrane, the diaphragmatic crura, and connective tissues. Weakening of these structures—due to aging, congenital defects like a short esophagus, or increased intra-abdominal pressure from coughing, obesity, pregnancy, or heavy...
