Which condition is a contra-indication for the use of a rigid LSO?

A rigid lumbar sacral orthosis (LSO) is primarily used to support the lumbar spine and restrict motion, often indicated following surgical procedures or significant injuries. However, recent major abdominal surgery is a critical contraindication for its use.

After such surgeries, the abdominal area may be healing from large incisions or internal procedures, and placing a rigid orthosis can impose excessive pressure on the abdomen. This pressure might result in complications such as disrupted healing, increased pain, or even damage to internal organs. The need to avoid any excessive movement or strain on the abdominal wall during the recovery period is vital, making the use of a rigid LSO inappropriate until healing has progressed sufficiently.

Other conditions mentioned, such as spinal cord injury, diabetes, and osteoporosis, might require careful consideration when fitting a patient for an orthosis but do not generally constitute outright contraindications. In cases of spinal cord injury, an LSO may even be beneficial for stability. Individuals with diabetes and osteoporosis must be monitored for their overall health and any potential complications, but these conditions do not inherently prevent the use of a rigid LSO.
