Does Loss of Spondylolisthesis Reduction Impact Clinical and Radiographic Outcomes after Minimally Invasive Transforaminal Lumbar Interbody Fusion.

Spine J 2021 Jun 9. Epub 2021 Jun 9.

Department of Orthopaedic Surgery, Hospital for Special Surgery, 535 East 70th Street, New York, NY, 10021, USA; Weill Cornell Medical College, 1300 York Ave, New York, NY, 10065, USA. Electronic address:

Background Context: Minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) is a common operative approach to address degenerative lumbar stenosis and spondylolisthesis which has failed nonoperative care. Compared to open TLIF, MI-TLIF relies to a greater extent on indirect decompression resulting in a heightened awareness of spondylolisthesis reduction among MI surgeons. To what extent intraoperative reduction is achieved as well as the rate and clinical impact of loss or reduction and slip recurrence remain unknown. Read More

Functional Ankle Range of Motion but Not Peak Achilles Tendon Force Diminished With Heel-Rise and Jumping Tasks After Achilles Tendon Repair.

Am J Sports Med 2021 Jun 11:3635465211019436. Epub 2021 Jun 11.

Department of Physical Therapy, University of Delaware, Newark, Delaware, USA.

Background: Deficits in sporting performance after Achilles tendon repair may be due to changes in musculotendinous unit structure, including tendon elongation and muscle fascicle shortening.

Purpose/hypothesis: The purpose was to discern whether Achilles tendon rupture reduces triceps surae muscle force generation, alters functional ankle range of motion, or both during sports-related tasks. We hypothesized that individuals who have undergone Achilles tendon repair lack the functional ankle range of motion needed to complete sports-related tasks. Read More
