thigh Right Thigh Skin Model 3D Printable STL File Converted from CT Scan 1.0.0

This model is the right thigh skin rendering of a 65-year-old male with left thigh myxoid fibrosarcoma. At the time of diagnosis, the patient had metastases to his lungs. The patient therefore underwent neoadjuvant radiotherapy, surgery, and adjuvant chemotherapy and was found to have an intermediate grade lesion at the time of diagnosis. The patient is still living with the metastatic disease at 2.5 years since diagnosis. This is an STL file created from DICOM images of his CT scan which may be used for 3D printing.

The thigh is divided into three compartments: the anterior, posterior, and adductor. After a femoral fracture or vascular injury in the thigh, increasing pressure within a compartment may threaten to compromise blood flow to muscles within the compartment, a syndrome known as “compartment syndrome.” Compartment syndrome is diagnosed clinically as “pain out of proportion to exam.” In patients that a clinical exam may not be obtained, such as those who are intubated or with a traumatic brain injury, a Stryker needle of each compartment may be performed.  The diagnosis of compartment syndrome is defined as pressures within 30 mmHg of diastolic blood pressure. Compartment syndrome is an emergency and thigh fasciotomies must be performed immediately to prevent compromise of muscles within the compartment at risk.

Thigh fasciotomies may be performed through a single incision for release of the anterior and posterior compartments, or a medial incision for decompression of the adductor compartment (less common). For the single incision technique, the incision is created laterally, and the fascia lata is incised. This exposes the anterior compartment, which is decompressed. The lateral intermuscular septum is then incised to decompress the posterior compartment.

This model was created from the file STS_022.
