Neurogenic heterotopic ossification, a rare bone formation in soft tissue, occurred in a patient with spina bifida. This ectopic bone formation complicated suprapubic cystostomy by causing Foley catheter balloon rupture.
Area of Science:
- Urology
- Orthopedics
- Neurology
Background:
- Neurogenic heterotopic ossification involves ectopic bone formation in patients with neurological disorders.
- A 33-year-old female with spina bifida and paraplegia presented with urinary issues.
- She underwent suprapubic cystostomy due to chronic urine leakage.
Observation:
- The patient experienced persistent urine leakage around the suprapubic catheter despite interventions.
- X-rays and CT scans revealed heterotopic bone formation bridging pubic diastasis.
- The ectopic bone's sharp edge was implicated in frequent Foley catheter balloon ruptures.
Findings:
- Heterotopic ossification in the pubic region was temporally linked to suprapubic cystostomy and urine leak.
- Complications included frequent Foley balloon rupture and difficulty with suprapubic catheter insertion.
- The ossification led to synostosis between the pubic bones.
Implications:
- This case suggests urinary tract-related factors may contribute to heterotopic ossification.
- Understanding these unique risk factors is crucial for managing neurological patients with urinary diversions.
- Further research is needed to explore the link between chronic urine leaks and ectopic bone formation.

Structural Joints: Cartilaginous Joints
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary or...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Structural Joints: Fibrous Joints
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
Bone Formation by Intramembranous Ossification
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...
Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...
