Comparison of the Otto Bock solid ankle cushion heel foot with wooden keel to the low-cost CR-Equipements™ solid ankle cushion heel foot with polypropylene keel: A randomized prospective double-blind crossover study assessing patient satisfaction and energy expenditure.

BACKGROUND: The International Committee of the Red Cross supports a worldwide program of prosthetic fitting and rehabilitation. In this context, a prosthetic foot was developed and widely distributed in least developed countries. STUDY DESIGN: Prospective, randomized, double-blind, controlled study. OBJECTIVE: To compare patient satisfaction and energy expenditure during ambulation between a low-cost prosthetic foot designed with a polypropylene keel (CR-Equipements™ solid ankle cushion heel, International Committee of the Red Cross) to a well-recognized solid ankle cushion heel foot with a wooden keel (solid ankle cushion heel foot, Otto Bock). METHODS: A total of 15 participants with unilateral transtibial amputation were evaluated using the two prosthetic feet in a randomized prospective double-blind crossover study. Main outcomes were patient satisfaction questionnaires (Satisfaction with Prosthesis Questionnaire and prosthetic foot satisfaction) and energy expenditure (oxygen consumption-mL/kg/min, oxygen cost-mL/kg/m, and heart rate-bpm). RESULTS: There were no significant differences between the two prosthetic feet for satisfaction and energy expenditure. CONCLUSION: The low-cost solid ankle cushion heel foot with polypropylene keel provides comparable satisfaction and similar energy expenditure as the solid ankle cushion heel foot with wooden keel. Clinical relevance The results of this study support the application and widespread use of the CR-Equipements™ solid ankle cushion heel foot. From a cost-effectiveness standpoint, patients are well satisfied and exhibit similar outcomes at a substantially lower cost.

Conditions found among pediatric survivors during the early response to natural disaster: a prospective case study.

BACKGROUND: Major natural disasters may provoke a mass casualty situation, and children tend to represent an important proportion of the victims. The purpose of this study was to prospectively record medical conditions presented by pediatric survivors of a major natural disaster to determine the type of medical specialists most needed during the acute phase of relief response. METHODS: After the 2010 Haiti earthquake, age, sex, date of presentation, diagnosis, and treatment provided were prospectively recorded for all patients less than 18 years old treated by a medical relief team. Patients were then allocated to 1 of the 2 groups: surgical (traumatism or surgical disorder) and medical (medical disorder). Medical activity lasted for 43 days. RESULTS: Four hundred seventy-one of the 796 treated patients were less than 18 years old. Two hundred forty-four (52%) were assigned to the surgical group and 227 (48%) to the medical group. As there was a substantial decrease in the number of new surgical patients registered on day 11 of activity, we arbitrarily defined an early period (until day 10 of activity) and a late period (beginning on day 11 of activity). Data obtained from the 147 new patients registered during the early period revealed 134 (91%) surgical patients and 13 (9%) medical patients. Eighty-eight percent of patients needed specialized care for traumatic orthopaedic lesions, and procedures under anesthesia or sedation were mainly (98%) performed for traumatic conditions. Data obtained for the 324 new patients registered during the late period revealed 110 (34%) surgical patients and 214 (66%) medical patients. There was a switch from high surgical needs to more routine medical and surgical care, with less procedures (88%) for the treatment of traumatic lesions. CONCLUSIONS: Pediatric orthopaedic surgeons have a major role to play in the acute phase of relief response to potentially minimize long-term physical and psychosocial disability associated with these complex injuries in growing patients. LEVEL OF EVIDENCE: Economic or decision analyses, level II.

Activity and impact on antibiotic use and costs of a dedicated infectious diseases consultant on a septic orthopaedic unit.

UNLABELLED: The Orthopaedic Service of the Geneva University Hospitals engages dedicated infectious disease (ID) specialists to assist in the treatment of infected patients. We investigated the daily clinical activity and the impact on antibiotic costs in the Septic Unit since 2000. METHODS: Retrospective analysis of various databases. Prospective survey of clinical activity from January 2008 to March 2008. RESULTS: According to the survey, the ID specialist performed 265 first-time and 1420 follow-up consultations (average of 11.4 consultations per working day). In 88% of cases the antibiotic regimen initiated by the surgeons was approved. When the ID specialist had to change antibiotic treatment, it was for de-escalation in 43.7%, discontinuance in 32.4%, and initiation in 24.4% of cases. From April 2007 to March 2008, the ID specialist decreased total antibiotic use by 43 DDD/100 patients-days (p=0.0006) in the Septic Unit. Direct antibiotic costs decreased by US$64,380 over the same period, equal to the annual salary of the ID specialist. There was no change in the number of recurrent infections. CONCLUSIONS: The main antibiotic-related activity of the dedicated orthopaedic ID specialist in Geneva our institution was to discontinue or adjust a pre-existing antimicrobial therapy. This activity significantly reduced antibiotic use and related costs on a septic orthopaedic unit.

Assessment of an electronic goniometer designed to measure equinus contracture.

To achieve more objective and repeatable measurements of equinus contracture, we developed the equinometer, a device that allows the measurement of ankle range of motion under controlled torque conditions. This study assessed its accuracy across different subjects and examiners. Two examiners used the equinometer to measure the angle of ankle dorsiflexion at 15 N x m torque on five subjects. Accounting for variation in measurements because of subjects, examiners, and placement of device, we used linear mixed-effects models. Accounting for the variation because of subject, different placements of the equinometer within each subject and the adjustment for the effects of examiner and trial sequence, the standard deviation was 0.94 degrees, 95% confidence interval (0.79 degrees, 1.13 degrees). An upper standard deviation of 1.36 degrees is felt to be acceptable for clinical investigation.
