67 The Effect of Local Halo Pin Care Reagents on Cranial Radial Compressive Stress (When Tightening Halo Pins)
Stephen H. Liu, MD
Thomas R. Lunsford, MSE, CO
Robert L. Waters, MD
  The halo fixation device is used widely for treating traumatic injury to the cervical spine. Complications can be minimized by retightening, increasing torque and practicing local pin care. The coefficient of friction at the halo ring/pin thread inte...

73 The SMART(R) Wrist-Hand Orthosis (WHO) for Quadriplegic Patients
John B. Makaran, MESc, P. Eng.
Douglas K. Dittmer, MD, FRCPC
Ralph O. Buchal, PhD
Dawn B. MacArthur, CO(c)
  The SMARTŪ Wrist-Hand Orthosis is a new method of providing grasping function for quadriplegic patients. The use of shape memory alloy allows for a new type of actuator and provides excellent function and ease of use.

77 A Volume-Adaptable Prosthesis for Ankle Disarticulation
Michael S. Pinzur, MD
John A. Angelico, CP
Michael J. Quigley, CPO
  Ankle disarticulation amputation in patients with peripheral vascular disease is sometimes complicated by delayed healing or residual limb volume fluctuation. The authors describe a method of producing a preparatory ankle disarticulation prosthesis t...

79 Bilateral Hip Disarticulation Management
Janet L. Rogers, MS, PTA
C. Dale Pape, MSEd, PT
Richard J. Thiele, CP
  The authors discuss the evaluation, impression, modification and fabrication of the device for-and rehabilitation of-a patient with bilateral hip disarticulations necessitated by severe decubitus ulcers secondary to a seventh thoracic level spinal co...

82 Distance Education Technology for Prosthetic CAD/CAM Instruction
Edward D. Lemaire, MSc
  The author discusses a course created to instruct prosthetic and orthotic clinicians on CAD/CAM principles and techniques. Through interactive computer graphics and standard telecommunications, students of the course studied the CAS-DaM, CANFIT-PL US...

88 Quantification of the Effect of Dorsi-/ Plantarflexibility of Ankle-Foot Orthoses on Hemiplegic Gait: A Preliminary Report
Sumiko Yamamoto, PhD
Masahiko Ebina, CPO
Shigeru Kubo
Hideo Kawai, RPT
Takeo Hayashi, CPO
Mitsuo Iwasaki, CPO
Toshio Kubota, MD
Shinji Miyazaki, PhD
  The authors discuss a series of studies done to establish an objective and quantitative method to determine the optimum dorsi-/plantarflexibility of an ankle-foot orthosis (AFO) for various patients.

95 The Syme Prosthesis Revisited
William Doyle, CP
Jerry Goldstone, MD
Dave Kramer, PT
  A unique design for medial-opening Syme prostheses has been developed to address issues of comfort, flexibility, strength, lightness and durability. Parallel goals of reducing fabrication complexity, and therefore time, as well as providing ease of a...
