Limb Lengthening Service of the Hospital for Special Surgery
There is a solution for people with short stature who are deeply dissatisfied with their height. Limb lengthening surgery to increase height can help individuals improve their confidence, body image, and overall happiness.
The Precice STRYDE Nail is an internal lengthening nail manufactured by Nuvasive inc. and is FDA approved. We use the Precice STRYDE nail which is now a weight bearing implant, and our experience with this has been very positive. The lengthening nail is telescopic and lengthens the bone in a very controlled fashion. An external magnet actuates the device and results in about 1mm of length per day. This translates into an inch per month. No external fixator is needed.
The usual goal of lengthening for stature for most patients is about 3 inches (8 cm). More than that amount cannot be achieved safely in one pair of bones during one lengthening. For more lengthening one needs to repeat the process in a second pair of bones. The maximum lengthening possible with the Precice nail is 8 cm (3.15 inches). Lengthening of the femurs (thigh bones) is the best first approach since bone healing and recovery is faster and the entire experience is easier than the tibias (leg bones). One can assume approximately one month of distraction for every inch (2.5 cm of lengthening). Lengthening does not begin until about a week after surgery. Therefore 3 inches of lengthening takes about 3 months.
Patients can bear weight with assistance the day after surgery and during the lengthening process. Use of a wheelchair is not needed, and this immediate mobility prevents tightness and muscle atrophy. After about 3-4 months patients can usually walk without assistance as the bone progressively heals and gets stronger. Removal of rods is necessary about one year after the procedure, and is an outpatient ambulatory surgery with a very quick recovery. No limitations on weight bearing are necessary at that time.
Lengthening for stature may be reimbursable by insurance in some cases, especially if there is any evidence of a hormonal or hormone treated related basis for the short stature, or if there is associated deformity.
We look forward to helping you through this journey.
