Musculoskeletal Ultrasound: An Orthopedician's View
Advertisement
Several times in our practice we orthopedic surgeons need to take assistance of imaging modalities to clinch the diagnosis . When time tested X- ray alone is not adequate, we resort to CT , MRI & now “the new –kid” on the block comes MSK ultrasonography (or Musculoskeletal Ultrasound).
Though I say new kid on the block, this is a modality which has proven itself over the last 2 decades in the West . We in India were very much aware of it, but did not routinely use it in our day to day practice, primarily because of
At this juncture, I would like to inform my fellow doctors about the use of this modality.
In my practice, I use this Imaging modality in several situations namely:
Though I say new kid on the block, this is a modality which has proven itself over the last 2 decades in the West . We in India were very much aware of it, but did not routinely use it in our day to day practice, primarily because of
- Lack of awareness of it’s potential
- & Inadequate training provided to the radiologists in their normal course of their post graduation.
At this juncture, I would like to inform my fellow doctors about the use of this modality.
In my practice, I use this Imaging modality in several situations namely:
- Infection of bone, joints and soft tissue- Musculoskeletal ultrasound picks up findings much earlier than an X- ray and can help in guiding the surgical approach.
- Post Operative infection especially in situations where implants and prosthesis are in place, which by their very presence preclude the use of MRI and sometimes even CT because of the artefacts created by the implants.
- Foreign bodies- particularly when the non—metallic foreign bodies like thorns and wooden splinters are present.
- Pediatric conditions like occult fractures, epiphyseal injuries, DDH ( Developmental dysplasia of hip) ,septic arthritis. For children, MRI becomes very scary modality because it has a very loud sound with claustrophobic conditions , the kids begin to panic and need to be sedated . CT is a radiation based modality and very harmful to growing skeleton .
- Soft tissue tumors – with the help of this modality, we can pick up the extent of the tumor, the vascularity, margins and even do an ultrasound- guided biopsy.
- Bone healing- in cases of fracture, where we have doubt on an X-ray, whether the bone has healed or not . Ultrasound can pick up callus (the new bone), which is not seen in an X-ray. Even the vascularity, that is the blood supply of surrounding tissues can be picked up on Doppler color flows of the ultrasound.
- Soft tissue injury like cut tendons and also joint pathologies- tendonitis and involvement of tendons of the joints, particularly the shoulder, ankles and knee joint.
- Situation where MRI cannot be used like patients with stents, pacemakers, implants, prosthesis or in patients suffering from claustrophobia who panic by name of MRI modality.
