Intermediate to long-term results of a treatment protocol for calcaneal fracture malunions.
Nonoperative management of displaced intra-articular calcaneal fractures may result in malunion affecting the function of both the ankle and the subtalar joint. The purpose of this study was to report the intermediate to long-term results of a treatment protocol for calcaneal fracture malunions. ⋯ This treatment protocol proved to be effective in relieving pain, reestablishing a plantigrade foot, and improving patient function. Because of the difficulty we encountered in restoring the calcaneal height and the talocalcaneal relationship in this group of patients with a symptomatic calcaneal fracture malunion, we believe that patients with a displaced intra-articular calcaneal fracture may benefit from acute operative treatment.

Despite a trend toward the use of regional anesthesia for orthopaedic procedures, there has been resistance to the use of interscalene regional block for shoulder surgery because of concerns about failed blocks and potential complications. ⋯ Interscalene regional block provides effective anesthesia for most types of shoulder surgery, including arthroplasty and fracture fixation. When administered by an anesthesiologist committed to and skilled in the technique, the block has an excellent rate of success and is associated with a relatively low complication rate.

Comparative StudyThe early effects of code 405 work rules on attitudes of orthopaedic residents and attending surgeons.
The impact of strict enforcement of Section 405 of the New York State Public Health Code to restrict resident work to eighty hours per week and the adoption of a similar policy by the Accreditation Council on Graduate Medical Education in 2002 for orthopaedic residency training have not been evaluated. Adoption of these rules has created accreditation as well as staffing problems and has generated controversy in the surgical training community. The purposes of this study were (1) to evaluate the attitudes of orthopaedic residents and attending surgeons toward the Code 405 work-hour regulations and the effect of those regulations on the perceived quality of residency training, quality of life, and patient care and (2) to quantify the effect of the work-hour restrictions on the actual number of hours worked. ⋯ On the basis of the survey data, the implementation of the new work-hour restrictions was found to result in a decrease in the number of hours worked per week for PGY-2 and PGY-3 residents and in an increase in work hours for PGY-4 residents. This could explain the definite difference between the attitudes expressed by the senior residents and those of the junior residents. Senior residents felt that their education was negatively impacted by the work rules, while junior residents expressed a more neutral view. However, senior residents did not believe that their operative experience was as negatively impacted as did junior residents. Although junior and senior residents and attending surgeons agreed that resident quality of life had improved, we were not able to determine whether this offset the perceived negative impact on education, continuity of care, and operative experience.

A cadaveric model of the throwing shoulder: a possible etiology of superior labrum anterior-to-posterior lesions.
It has been speculated that a shift of the throwing arc commonly develops in athletes who perform overhead activities, resulting in greater external rotation and decreased internal rotation caused by anterior capsular laxity and posterior capsular contracture, respectively. Osseous adaptation in the form of increased humeral and glenoid retroversion may provide a protective function in the asymptomatic athlete but cannot explain the pathological changes seen in the shoulder of the throwing athlete. Therefore, the objective of the present study was to examine the biomechanical effects of capsular changes in a cadaveric model. ⋯ A posterior capsular contracture with decreased internal rotation does not allow the humerus to externally rotate into its normal posteroinferior position in the cocking phase of throwing. Instead, the humeral head is forced posterosuperiorly, which may explain the etiology of Type-II superior labrum anterior-to-posterior lesions in overhead athletes.
