Summary
A rare osteochondroma bone tumor in the ischial ramus caused sciatica, mimicking lumbar radiculopathy. This case highlights the importance of considering unusual pelvic tumor locations in sciatica diagnosis.
Area of Science:
- Orthopedic Surgery
- Oncology
- Radiology
Background:
- Osteochondromas are common benign bone tumors, typically occurring in long bones.
- Pelvic osteochondromas are infrequent, with the iliac crest being the most common site.
- Ischial ramus involvement by osteochondroma is exceptionally rare.
Observation:
- A 25-year-old male presented with sciatica symptoms.
- Imaging revealed an osteochondroma originating from the ischial ramus.
- The tumor's location mimicked lumbar radiculopathy (L4-L5-S1).
Findings:
- The ischial ramus osteochondroma was the cause of the patient's sciatica.
- This presentation is a rare instance of pelvic osteochondroma causing radicular symptoms.
- The diagnosis was initially challenging due to the atypical location.
Implications:
- This case underscores the need to consider rare pelvic bone tumors in the differential diagnosis of sciatica.
- Accurate diagnosis requires thorough imaging and awareness of unusual tumor presentations.
- Understanding rare osteochondroma locations can improve patient outcomes and prevent misdiagnosis.

01:09Bones of the Upper Limb: Radius
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.

01:29Blood and Nerve Supply to the Bones
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

01:19Bones 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...
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...
01:23Degenerative 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...
01:10Bones 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...
