Custom Orthosis and Splint Fabrication

The terms orthosis and splint are often used interchangeably; simply put, an orthosis is another name for a custom splint.  Certain injuries or conditions require the fabrication of an orthosis that is custom made for you.  Custom orthoses and splints are designed to protect patients while recovering from overuse injuries, sprains, fractures & dislocations, sports-related injuries, arthritic conditions, nerve disorders, tendon repairs, and other post-operative conditions.

High quality custom-tailored orthoses

Our hand therapists are experts at creating high quality custom-tailored orthoses.  The splint fitting and fabrication process is specific to the purpose of the splint.  Splints may serve different purposes and are designed to:


  • Immobilize and rest joints and/or tendons
  • Protect acute injuries or surgeries
  • Assist range of motion and increase function
  • Provide protective positioning to allow early motion
  • Stretch connective tissue and increase joint mobility
  • Prevent or correct joint deformity
  • Maintain alignment of a joint after joint replacement

Splints are fabricated onsite using low temperature thermoplastic materials that are molded to the patient’s injured body part.  The splints are then secured in place using Velcro straps.  The process typically takes 15 to 45 minutes depending on the complexity of the splint.  Patients leave the clinic with the splint the same day.  We offer an array of splint colors to choose from including black, pink, purple, red, bright green, blue, white, and steel blue.

We fabricate a variety of upper extremity splints from small finger splints to larger orthoses that immobilize the whole hand, wrist, and elbow. We encourage patients who are returning to sports to bring in their baseball mitts, goalie gloves, and ski gloves for proper fit.  We are also experts at sizing of Silver Ring Splints and measuring and fitting static progressive devices such as Joint Active Systems (JAS) or Stat-A-Dyne. In addition, we offer Exos semi custom orthoses which are available for return to sport in lieu of casting upon physician request. 

We fabricate the following orthoses at our clinic:

  • Hand-based thumb spica
  • Forearm-based thumb spica
  • Wrist immobilizer
  • Dorsal blocking
  • Static finger extension for Dupuytren’s
  • Resting hand
  • Mallet finger / tip protector
  • Trigger finger
  • Serial casting
  • Dynamic PIP extension
  • Static progressive MP flexion
  • Static progressive composite finger flexion
  • Dynamic wrist flexion and extension
  • Dynamic forearm supination and pronation
  • Long arm (with or without the wrist)
  • Exos semi-custom orthosis

What our Patients are Saying

We are so grateful for Emily’s wisdom and tenacity during our daughter’s injury. In every possible way, Emily exceeded our expectations. She advocated with the surgeon for us, she was creative in her approach to therapy, and she overturned many obstacles that came our way during recovery. But even more importantly, Emily was kind, fun, and compassionate with our daughter, making this painful journey back to health a positive experience. We have always felt like we were in excellent hands, literally! I cannot recommend Emily and her team enough.

After requiring surgery for a torn ACL due to a sports injury, Kiley Steinriede from Proliance Sports Therapy guided my journey to recovery from re-learning to walk to returning to play the sports I love. Kiley’s mix of real-world experience, attention to detail, empathy, motivation, care, humor and emotional support is what made it all possible. I couldn’t have done it without her.

I would not have had a successful rehabilitation experience were it not for Kiley. She was tirelessly diligent, attentive and knowledgeable about what was best for my post-op ACL rehab at each stage of the recovery process. But more importantly, her humor and care for me as an individual, not just a patient, was the greatest encouragement as I went through physical therapy. Because of her, I looked forward to coming in to sessions and her optimism and charisma no doubt expedited my rehabilitation.

Laura Browne has provided excellent and effective physical therapy to both myself and my husband in the past. Now, I am thankful to have her professional knowledge and caring treatment as I struggle with the dual problems of surgery recovery and recurrence of significant lymphedema near the surgical site. Laura fluidly adapts to the limitations that the lymphedema imposes on a "normal" path to surgery recovery, always finding effective exercises to substitute for ones that are not practical for the situation. Throughout, her communication is informative, honest, and encouraging. Laura Browne is a credit to the high standards Proliance seeks in their employees.

Kudos to Proliance Sports Therapy & Rehab for the superb treatment I’ve received over the past several months. A spring ski mishap resulted in my fractured arm near my shoulder and that led to surgery requiring a steel plate with several pins; in the same fall, I tore my rotator cuff in my ‘other’ arm. With both arms basically ‘out of commission’ I was scared and worried about how I’d ever use my arms normally again. Laura has amazed me with all of her knowledge and capability as she has led me through a PT Program that now has me functioning as normally as I was before... I am so thankful that I chose Proliance Sports Therapy for my rehab; should I ever need rehab again, I would choose Proliance in a heartbeat!


14 months ago I had total shoulder replacement on my right shoulder at Issaquah Proliance Orthopedics & Sports Medicine. Surgery went great! Started Physical Therapy 1 week later. My Therapist (Cathy Van Lith) discussed my goals with me and set a plan. Everybody is so friendly and nice and make you feel welcome - you feel like family. I still have a long way to go but I know I couldn’t be in better hands. I have friends that have recommended that have gone and they can’t thank me enough for the recommendation.

Only place I’ll go: In the past, we’ve had a hard time finding good medical care. My wife found Proliance via recommendation from her OB who had his hip replaced at Proliance. We have since had 2 surgeries each that have required intense physical therapy at Proliance in Issaquah. The net result is that I won’t go anywhere else in the future. My expectations have been exceeded by both the care I’ve received and the support to get through the PT. Sounds silly I suppose, but I feel like I’m treated like a person, not just a body part that needs fixing. I’ve worked with Emily specifically and her PTs are truly a standout, they are awesome, pushing you while supporting, plus have been completely connected with my surgeon and with each other. If you need care, this is a good choice.

Patrick understood how difficult it was for me to be sidelined and how frustrated I felt. He pushed me to work harder and celebrated with me when I would hit a goal. Patrick was realistic about timelines, knew when to push me and when to hold me back so I didn't injure myself again. He also did a great job of making our sessions fun and different. I would highly recommend Proliance Sports Therapy & Rehabilitation. This group of people truly cares about your recovery, goals, physical and emotional well being and long term health. I now feel confident to trail run, bike, ski and have even learned how to rock climb!

Kyle Mark was amazing! He patiently rehabbed my knee back and specifically researched exercises that would support my love of tennis, after I tore my meniscus. I left after the expected period of time and was able to resume tennis. Unfortunately, I caused an additional issue within the knee while hiking shortly after recovery and, even though I had moved out-of-state, he suggested exercises to get me back on track. I am 100% back to normal and so thankful that he took the time and shared his knowledge with me. Proliance is lucky to have such a smart, caring and dedicated physical therapist in their office.


After finger surgery four years ago on my left hand and two years ago on my right hand. Stephanie helped me through many therapy appointments. She also instructed me on home exercises. She is very professional and will go the extra mile to get the results we both wanted. I would highly recommend her.
