Aspen® TLSO

The Aspen® Lumbosacral Bracing System™ provides superior motion restriction, increased comfort, and better patient outcomes. A complete set consists of four LSO sizes and three TLSO upgrade kits.

Code L0462 Approved


Modular Design
The modular design of the Aspen® Lumbosacral Bracing System™ lets you progressively tailor the amount of motion restriction to the changing needs of each patient. By removing the shoulder straps, torso control straps, or the padded chest panel, the system can be “stepped down” to parallel the overall progress of the patient.

Rigid Layered Support
Forms a structurally rigd polyethylene cylinder that restricts motion, yet is easy to trim or shape while on the patient.

VectorPoint™ Chest Panel
Adjusts to the height and profile of each patient. This padded chest panel anchors the front and back of the brace to an anterior vector point in teh upper thoracic region.

Torso Control Straps
Further limit flexion and rotation by linking the padded chest panel to a second location on the back brace.

Easy LeverLatch™ Closure
Gives the patient a strong mechanical advantage to easily and effectively tighten the orthosis for better immobilization and pain relief.

CushionFlex Tabs™
Soften the edges of the orthosis. Can be cut to further splay outward or trimmed back for better comfort.

Frequently Asked Questions

When do Aspen® TLSO pads need to be changed?
The TLSO unit is to be worn over a layer of clothing, which will assist in keeping your pads clean. A second set of pads is recommended. Replace and wash your first set as needed. With pads averaging approximately 8 hours for drying, the second set of pads should be used during the drying process. Rotating pads on a regular basis will prolong the life of the pads.
My patient has lost weight and the brace seems too loose. How do I change the size?
The TLSO is designed to attain a custom fit, whether your patient looses or gains weight following the initial fitting. The side panels are easily adjusted to the proper size to achieve the optimal fit. Please refer the fitting instructions located under TLSO Instruction sheet . Please refer the fitting instructions located on the website under TLSO Instruction sheet. You can review these instructions on-line and print the complete instruction sheet.
Why doesn’t the LeverLatch™ lie flat when the brace has been completely tightened?
The LeverLatch™ doesn’t lie flat because the process of tightening has not been completed. Adjust the upper and lower straps to desired tightness and then pull the slack out of the center strap. Final LeverLatch™ position should be as shown. Adjust the upper and lower straps to desired tightness and then pull the slack out of the center strap. Final LeverLatch™ position should be as shown.
How do I measure for the correct size TLSO?
Please refer to the TLSO Instruction sheet directions for use
How do you adjust the size of the brace?
Please refer to the TLSO Instruction sheet Assembly section.

To determine the correct slot setting, measure the patient’s circumference at the waist and lower rib margin and average the two numbers. Attach the side panels to the back panel by sliding the ends of the back panel into the curved slots so the end is hidden under the side panels. Using the average measurement, seat the rivets in the appropriate SureSlot™ openings and pull firmly until they snap into place.

Comparison of Motion Restriction and Trunk Stiffness Provided by Three Thoracolumbosacral Orthoses (TLSOs)

STUDY DESIGN: Four conditions (three orthoses, one no orthosis), full cross-over, randomized order, 12 subjects tested 3 months after a lumbar surgical arthrodesis. OBJECTIVES: To assess whole torso and lumbar motions and comfort for each orthoses condition during performance of activities of daily living. SUMMARY OF BACKGROUND DATA: Previous noninvasive studies measured whole torso (not just lumbar) movement. Recent development of a low profile, flexible, strain-gauged device (“Lordosimeter”) facilitated this study. MATERIALS AND METHODS: The Lordosimeter was taped to the skin along the midline of the lumbosacral region. Orthoses studied were Boston anterior opening, Aspen lumbosacral, and Cybertech. Specified activities of daily living were performed for each orthosis condition. Subject effort during the flexion/extension task was assessed by surface electromyography (EMG). Comfort was assessed by visual analog scale. RESULTS: There were no significant differences in EMG between orthoses. For lumbar flexion, trunk flexion, total lumbar motion, and total trunk motion, the mean values for Aspen and Boston (but not Cybertech) were significantly smaller than for no orthosis for most of the tasks and there were no significant differences between Aspen and Boston. The total lumbar motion allowed by each orthosis (averaged across tasks and relative to the no orthosis condition) was 81% for Aspen, 79% for Boston, and 97% for Cybertech. The comfort rating averaged across tasks was 2.24 for Aspen, 4.12 for Boston, and 3.92 for Cybertech (0 = very comfortable, 10 = very uncomfortable). Aspen was significantly more comfortable than Boston or Cybertech. Boston and Cybertech did not differ significantly. CONCLUSIONS: The Lordosimeter is useful for measuring lumbar motion during orthosis wear. The Aspen and the Boston orthoses provided significant flexion-extension motion restriction compared with no orthosis, but for almost all of the motion measures did not differ from each other. The Cybertech did not differ significantly from the no orthosis condition. The Aspen orthosis was rated significantly more comfortable than the Boston or the Cybertech.

Selected Quotations

“The major objectives of lumbosacral orthosis use are to reduce low back pain 1-4 and to increase the likelihood of solid fusion development after surgical bone grafting across two or more vertebrae.5-7”

(Pg. 2359)

“…The Boston anterior opening orthosis…has been used by the senior author for a number of years for postoperative immobilization, but fitting of it generally requires more than one visit to a skilled orthotist and it can be uncomfortable for some patients. Fitting of the two orthoses selected for comparison in this study is simpler and can be performed in one visit. One of them (Aspen Lumbosacral Orthosis, Long Beach, CA) can be modified to optimize the fit by adjusting the lower edge and by bending the lumbar support rods to produce the desired amount of lumbar lordosis.”

(Pg. 2359)

“In conclusion, for limiting lumbar motion, the Aspen LSO was found to be equal to the Boston orthosis and for comfort, the Aspen was found to be superior. Based on these findings, and on its ability to be fit and customized at the bedside, the Aspen LSO appears to be the orthosis of choice.”

The Incidence of Skin Breakdown Associated with Use of Cervical Collars

The most common adverse complication associated with cervical immobilization is skin breakdown. The purpose of this prospective, descriptive study was to assess the incidence of tissue breakdown associated with cervical immobilization. In this convenience sample of 484 patients, skin breakdown was noted in 33 (6.8%) patients. All cases of documented skin breakdown were stage I or II, with only 2% (0.4%) patients having stage III breakdown. Days in cervical collar is a significant predictor of skin breakdown, along with presence of edema. Results from this study demonstrate that there is a very low incidence of complications of skin breakdown associated with the use of Aspen cervical collars. The collars are safe and effective to use in patients with actual or suspected head or spine injuries.
