10.1055/b-0035-106396 21 Ventral Subaxial Spine Constructs 21.1 History Historically, attempts at the clinical application of ventral spinal instrumentation met with varying degrees of success. 1 , 2 Each of these…
10.1055/b-0035-106413 38 Biomechanical Testing Up to this point in the book, armchair biomechanics have in a sense been applied to the clinical arena—that is, physical, kinematic, and biomechanical principles have…
10.1055/b-0035-106399 24 Lumbosacral–Pelvic Constructs The region of the lumbosacral junction is exposed to significant axial, translational, and rotational loads; bending moments; and stresses. An appreciation of the sacral anatomy that…
10.1055/b-0035-106400 25 Regional Nuances Multiple factors affect the efficacy of a spinal implant. These include the following: (1) length of the construct; (2) spinal access for decompression, fusion, and instrumentation;…
10.1055/b-0035-106410 35 Bed Rest and Traction Bed rest and traction are infrequently considered from a biomechanical perspective. This is indeed unfortunate. Problems including pulmonary and integument complications, as well as…
10.1055/b-0035-106412 37 Exercises, Conditioning, and Other Nonoperative Strategies Pain of spinal origin is multifactorial. 1 Exercises for the management of spinal disorders are designed to diminish pain and to increase…
10.1055/b-0035-106411 36 Spinal Bracing The achievement of spinal stability is optimized by (1) appropriate and not excessive decompression, (2) appropriate bone graft or spacer placement (fusion), (3) appropriately placed internal…
10.1055/b-0035-106409 34 Construct Failure and Failure Prevention: The Decision Making Process In this chapter, focus is placed on construct failure and failure prevention. Seven scenarios have been defined as worthy…
10.1055/b-0035-106393 18 Construct Design For the purposes of the discussion presented in this chapter, four terms require definition: (1) construct, (2) implant, (3) assembly, and (4) construct design. Construct is…
10.1055/b-0035-106392 17 Quantitative Attributes of Spinal Implants A thorough understanding of the forces applied to the spine and, in turn, resisted by spinal implants is essential. These applied forces are…
