This study is being done to assess the impact of arm length and abdominal (belly) width on patient performance of daily self-care activities following multiple level spinal fusions. The study will also assess if the number of levels operated on in the spinal fusion procedure affects your ability to perform Activities of Daily Living (ADL) and how long after surgery do the difficulties/limitations persist.


This is a prospective, single-center study of adult patients undergoing long segment spinal fusions to the pelvis (>5 levels).

Health Related Quality of Life Outcome (HRQOL) consisting of the Oswestry Disability Index (ODI), Visual Analog Scale, EQ-5D, Scoliosis Research Society-22 and 30 (SRS-22 and SRS-30) and the Lumbar Stiffness Disability Index (LSDI) will be collected preoperatively, 6 weeks, 3 months, 6 months, 12 and 24 months. All measures will be collected during clinic visits.

Primary and secondary objectives The primary objective is to determine the impact of body habitus on postoperative ADLs in patients undergoing long segment spinal fusions.

The secondary objective will be to determine if the number of levels of fusions impact the ability to perform ADLs and to study how long after surgery do the difficulties/limitations persist.

Study procedures Enrolled subjects meeting eligibility criteria and provide consent will be approached by the study coordinator and explained the purpose of the study, risks and benefits to participation, and queried about their interest in participation. Patients consenting to the study will have the following measurements performed by the clinician with an evaluation prior to surgery, during their 6 week, 3 month, 6 month, 12 and 24 month postoperative visits.

  1. Waist circumference using a measuring tape will be obtained from midway between the last ribs and the iliac crest as suggested by the World Health Organization and the International Diabetes Federation.
  2. The arm span (wingspan) or reach will be measured. To measure the arm span, the patient will be asked to stand against the wall with their arms extended sideways at a ninety-degree angle. Using a measuring tape, the distance from the tip of the middle finger of one hand to the tip of the middle finger in other arm will be measured and recorded.
  3. The distance from the ground to the tip of middle finger will be measured while the patient is asked to touch their toes with knees fully extended.

As mentioned, all study patients will complete Health Related Quality of Life Outcome (HRQOL) consisting Oswestry Disability Index (ODI), Visual Analog Scale, EQ-5D, Scoliosis Research Society-22 (SRS-22) and the Lumbar Stiffness Disability Index (LSDI) at 6 weeks, 3 months, 6 month, 12 and 24 months.

Data will be collected in a password-protected file and will be stored in an electronically secure environment, as specified in the research data security plan (RDSP).

Follow-up by the research coordinator as part of this study will not necessarily preclude or replace any follow-up by the treating physician or nursing staff as part of the routine standard of care.
