Outcome study of children, adolescents, and adults with sacral agenesis.

J Pediatr Orthop 2007 Sep;27(6):682-5

Department of Orthopaedic Surgery, University of Michigan, Ann Arbor, MI, USA.

Musculoskeletal functional outcome was assessed in children and adults with sacral agenesis and no myelomeningocele. General health, musculoskeletal function, and psychosocial adjustment were assessed in 16 sacral agenesis patients (10 males, 6 females; mean age, 14 +/- 5 years) using previously validated patient and parent self-report questionnaires. Radiographs were reviewed to classify each patient by Renshaw type. Most patients were happy with their looks, and all felt that their general health was good to excellent. Patients reported being limited in function by their low back and distal lower extremities. Half were limited by pain. They reported problems functioning in physically demanding situations, although most were able to participate in low-demand physical activities. No relationship was found between pain and Renshaw type nor between overall satisfaction and Renshaw type.

Women in surgical residency training programs.

J Bone Joint Surg Am 2003 Dec;85(12):2477-80

2912 Taubman Center, Box 0328, University of Michigan Medical School, 1500 East Medical Center Drive, Ann Arbor, MI 48109-0328, USA.

Background: Increasing numbers of women are entering surgical fields. The purpose of this study was to assess whether orthopaedic surgery is significantly different from other surgical fields in the recruitment of women to training programs.

Methods: We analyzed data from the American Association of Medical Colleges as reported in annual issues on medical education in the Journal of the American Medical Association for the years 1970 to 2001, excluding 1975. Using linear regression models, we analyzed two factors: changes in the percentage of women within orthopaedic residencies (i.e., the ratio of men to women) and changes in the percentage of all female residents who choose to enter orthopaedics compared with other types of surgical residencies.

Results: The percentage of women in the entering classes of medical school has increased from 11.1% in 1970 to 47.8% in 2001, while the percentage of women in orthopaedics has increased from 0.6% in 1970 to 9.0% in 2001. Orthopaedic residencies have the lowest percentage of women compared with all other primary surgical specialties. Only thoracic surgery, a field entered secondarily after the completion of general surgical training, has a lower percentage. The increases in the percentage of women in orthopaedics over the past thirty years have been significantly lower than those in every other primary surgical field (including general surgery, obstetrics and gynecology, ophthalmology, otolaryngology, and urology), except neurosurgery, and are markedly different from the percentages of women in the entering classes of medical school. The percentage of all female residents who choose an orthopaedic residency is 0.6%, a number that has not changed over the past twenty years.

Conclusions: Orthopaedic surgery has not had the same success in recruiting female trainees that other surgical fields have had. Furthermore, there appears to be a leveling of the recruitment rate over the past two decades, indicating that the higher numbers of women entering medicine will not be sufficient to improve gender representation in orthopaedic surgery training.

Bladder cancer facts: accuracy of information on the Internet.

J Urol 2003 Nov;170(5):1756-60

Department of Urology, University of Michigan, 1500 E. Medical Center Drive, Box 0330, Ann Arbor, MI 48109-0330, USA.

Purpose: Patients continually seek information regarding the etiology, diagnosis, management and treatment of bladder cancer. The Internet has a growing number of health web sites and it is a tremendous resource for medical information. We examined the accuracy and completeness of bladder cancer sites on the World Wide Web.

Materials And Methods: Internet searching was performed by retrieving the first 30 universal resource locators from 8 popular search engines using the search term bladder cancer. A total of 38 independent web sites were evaluated. Other sites were inaccessible, duplicates or only contained linked pages. Two reviewers evaluated the accuracy and completeness of information using a predetermined 41-point checklist rating instrument that evaluated essential information related to bladder cancer. The kappa statistic was used to evaluate interrater variability.

Results: The mean kappa statistic for evaluable variables was 0.70. Most nonevaluable variables had excellent agreement, indicating good overall interrater reliability. No rating factor was present on 100% of sites. Eight factors were present and accurate on 80% to 90% of web pages and related to signs/symptoms, risk factors, diagnostic tests and treatment of early stage disease. Six factors were inaccurate on 32% of sites, including incidence (7), staging (3), recurrence (1), and treatment of early invasive (1) and metastatic (1) disease.

Conclusions: Bladder cancer information retrieved from the majority of medical web sites was incomplete. However, general information relating to presentation, diagnosis, staging and treatment of low stage disease was present and accurate on most sites. Although inaccurate information was detected on 32% of the sites, it tended to be related to outdated information. It is reasonable to refer patients to select comprehensive web sites to obtain pertinent information about bladder cancer.

Ultrasound of the navicular during the simulated Ponseti maneuver.

J Pediatr Orthop 2003 Mar-Apr;23(2):243-5

University of Michigan Health System, Mott's Children's Hospital, Ann Arbor, Michigan 48109-0252, USA.

Nonoperative treatment of the equinovarus foot has had a recent resurgence because of popularization of the Ponseti casting method. This method is based in part on reducing the talonavicular joint by moving the navicular laterally and the head of the talus medially. This study dynamically demonstrates the effect of a simulated Ponseti manipulation on the navicular.

Glenoid inclination is associated with full-thickness rotator cuff tears.

Clin Orthop Relat Res 2003 Feb(407):86-91

Orthopaedic Research Laboratories and University of Michigan Shoulder Group, University of Michigan, Ann Arbor, MI, USA.

Anatomic factors, such as a hooked acromion, have been associated with rotator cuff disorders. Orientation of the glenoid relative to the scapula has been implicated in shoulder instability, but it has not been linked to rotator cuff disorders. The purpose of the current study was to test the hypothesis that superior inclination of the glenoid is associated with full-thickness rotator cuff tears. Glenoid inclination angles were measured from 16 shoulder radiographs of a convenience sample of eight cadavers in which one shoulder had an intact rotator cuff and the other shoulder had a full-thickness rotator cuff tear. Glenoid inclination angles for shoulders with rotator cuff tears were compared with contralateral normal shoulders using nonparametric statistical analysis. The glenoid inclination angle was greater in cadaver shoulders having full-thickness rotator cuff tears (98.6 degrees ) than in shoulders without tears (91.0 degrees ). A second experiment was done to assess the reliability of using 34 Grashey view radiographs from a clinical population to measure glenoid inclination angle. A method to measure the glenoid inclination on Grashey views was tested and was found to correlate with the inclination angles measured on cadaveric scapulae. Intrarater reliability of measurements from clinical Grashey views was 0.93, and interrater reliability was at least 0.88.

Curve progression in scoliosis associated with Chiari I malformation following suboccipital decompression.

J Spinal Disord Tech 2002 Oct;15(5):410-4

Department of Orthopaedic Surgery, University of Michigan, Ann Arbor, USA.

Nine children with scoliosis and Chiari I malformations were followed 1-11 years after suboccipital decompression. Eight also had syringomyelia. Despite initial curve stabilization, at final follow-up eight curves were of the magnitude to require spinal fusion. Neither bracing nor secondary neurosurgical procedures arrested progressive curves.

Melanoma information on the Internet: often incomplete--a public health opportunity?

J Clin Oncol 2002 Jan;20(1):134-41

Department of Dermatology, University of Michigan Health System, 1500 E. Medical Center Dr., Ann Arbor, MI 48109-0946, USA.

Purpose: To assess the accuracy and completeness of information regarding melanoma on the Internet, retrieved by use of search engines.

Methods: The first 30 uniform/universal resource locators (URLs) from each of eight search engines using the search term "melanoma" were retrieved for evaluation of accuracy and completeness using a 35-point checklist rating system instrument. Four reviewers independently rated each of 35 sites, and one reviewer rated all 74 assessable sites. Kappa statistics were used to evaluate interrater variability.

Results: A total of 74 assessable Web sites were evaluated. The remainder were inaccessible, link pages only, or duplicates. Thirty-five Web sites were each independently rated by four reviewers. The remaining 39 Web sites were each rated by one reviewer. The mean kappa statistic for all variables and all rater pairs for which a kappa could be calculated was 0.824, indicating excellent overall inter-rater reliability. The majority of Web sites failed to include complete information on general information, risk factors, diagnosis, treatment, prevention, and prognosis. Ten Web sites (14%) contained a total of 13 inaccuracies, most relatively minor.

Conclusion: Medical information retrieved with the search term melanoma was likely to lack complete basic melanoma information and contained inaccuracies in 14% of sites. Health care providers can help patients by recommending comprehensive and accurate Web sites for patient review, by working to create accurate and thorough Web-based health information material, and by educating patients and the public about the variability in completeness and accuracy.
