Registered under NPI 1033404306 as a diagnostic ultrasound radiology group, MSK-US operates from Spring Street in La Mesa Village, providing musculoskeletal sonographic imaging for East County referral sources. The facility's musculoskeletal ultrasound studies for shoulder rotator-cuff tears, knee ligament integrity, and tendon pathology serve referral patterns from chiropractic and orthopedic providers including La Mesa Spine Center. Diagnostic ultrasound avoids ionizing radiation entirely, making it a first-line imaging choice for soft-tissue injuries, joint effusions, and guided needle-aspiration procedures. The 91941 ZIP code location on Spring Street places the center in the heart of La Mesa Village, accessible to the broader residential base along La Mesa Boulevard and Avocado Boulevard in the Casa de Oro corridor. Soft-tissue pathology identified on MSK-US scans informs downstream manual therapy and rehabilitation plans, with myofascial and trigger-point conditions overlapping the treatment scope of Bodywork by Bobbi Wellness Center. The most technically demanding studies include dynamic real-time ultrasound evaluation of tendon subluxation under load and ultrasound-guided aspiration of calcific tendinitis deposits in the supraspinatus and infraspinatus tendons.
