Areas Of Specialty

The orthopedic surgeons of Sports and Spine Orthopaedics are all well trained from the top programs throughout the country. Our expertise covers a wide spectrum of injuries in patients of all ages, including fractures, sports medicine injuries, spine injuries, osteoarthritis issues, and hand and wrist injuries. We focus on nonoperative treatment of all musculoskeletal problems and strive to get patients better without the need for surgery.

When surgery is required to resolve the problem, our surgeons specialize in minimally invasive procedures that result in less pain and less tissue damage—resulting in easier and faster recoveries. A majority of the more complex surgical procedures are performed on an outpatient basis.


Outpatient Surgical Procedures

Our Torrance location offers a beautiful, private surgery center exclusively for our doctors to perform various types of surgical procedures including arthroscopy (shoulder, knee, hip, ankle), fracture fixation, total knee and shoulder replacements, minimally invasive spine procedures, tendon and ligament reconstructions, endoscopic and arthroscopic hand and wrist procedures, and pain management. Our anesthesia department specializes in performing nerve block procedures that allow patients to return home shortly after the surgery without pain—even for bigger operations such as total knee and shoulder replacements.
