Distal rectus femoris surgery in children with cerebral palsy: results of a Delphi consensus project

PurposeThe purpose of this study was for an international panel of experts to establish consensus indications for distal rectus femoris surgery in children with cerebral palsy (CP) using a modified Delphi method.MethodsThe panel used a five-level Likert scale to record agreement or disagreement with 33 statements regarding distal rectus femoris surgery. The panel responded to statements regarding general characteristics, clinical indications, computerized gait data, intraoperative techniques and outcome measures. Consensus was defined as at least 80% of responses being in the highest or lowest two of the five Likert ratings, and general agreement as 60% to 79% falling into the highest or lowest two ratings. There was no agreement if neither threshold was reached.ResultsConsensus or general agreement was reached for 17 of 33 statements (52%). There was general consensus that distal rectus femoris surgery is better for stiff knee gait than is proximal rectus femoris release. There was no consensus about whether the results of distal rectus femoris release were comparable to those following distal rectus femoris transfer. Gross Motor Function Classification System (GMFCS) level was an important factor for the panel, with the best outcomes expected in children functioning at GMFCS levels I and II. The panel also reached consensus that they do distal rectus femoris surgery less frequently than earlier in their careers, in large part reflecting the narrowing of indications for this surgery over the last decade.ConclusionThis study can help paediatric orthopaedic surgeons optimize decision-making for, and outcomes of, distal rectus femoris surgery in children with CP.Level of evidenceV     

The surgical anatomy of the superior gluteal nerve and anatomical radiologic bases of the direct lateral approach to the hip

Summary In view of the increasing popularity of the direct lateral approach to the hip joint for hemi- or total hip arthroplasty, the location of the superior gluteal nerve (SGN) was studied. This nerve is in danger when using a transgluteal incision. In 20 embalmed specimens the relation of the SGN to the tip of the greater trochanter (TT) was studied as well as the relation to the iliac crest. For this purpose macroscopy, microscopy and CT were used. In 13 hips a so-called most inferior branch was found at an average of 1 cm distal to the inferior branch, the main trunk of the nerve. There was substantial variation in the course of both the inferior and the most inferior branch of the SGN. In order to prevent nerve damage, proximal extension of the transgluteal incision should be limited to 3 cm cranial to TT. Furthermore the incision has to be confined to the distal one third of the distance TT-iliac crest. In tall people extra care should be taken.

Anatomie chirurgicale du nerf glutéal supérieur et bases anatomo-radiologiques de l'abord latéral direct de la hanche

Résumé Les recours de plus en plus fréquent à la voie latérale directe de la hanche pour les prothèses totales ou cervico céphaliques nous a conduit à étudier la localisation du nerf glutéal supérieur (SGN) qui est exposé lors de l'incision transglutéale. Les rapports du SGN avec le sommet du grand trochanter (TT) et avec la crête iliaque ont été étudiés sur 20 cadavres embaumés. Nous avons eu recours à l'étude macroscopique, microscopique ainsi qu'au scanner. Dans 13 cas nous avons mis en évidence une branche très inférieure, donc plus distale, située 1 cm en moyenne en dessous de la branche inférieure habituelle de bifurcation du tronc principal. Il existait des variations importantes dans les trajets de ces deux branches inférieures. Afin de prévenir une lésion chirurgicale du nerf, l'incision transglutéale ne doit pas aller au delà de 3 cm du sommet du grand trochanter, de plus l'incision doit être confinée en dessous du tiers distal de la ligne joignant le grand trochanter à la crête iliaque.

     

The impact of Medicaid adoption of the Medicare fee schedule

In this article, the authors simulate the effects on Federal and State Medicaid expenditures of increasing Medicaid fees to Medicare fee schedule (MFS) levels. Strict adoption of the MFS by the States would increase total Medicaid spending by approximately 4 percent, $2.5 to $2.9 billion. Because Medicaid fees vary across States, so does the impact of adopting the MFS. Medicaid spending would increase significantly in some wealthy States with large Medicaid populations and in a few small, relatively poor States. Some States currently pay more than the MFS for obstetrical services. If these fees continued at higher levels for obstetrical care, total Medicaid spending would increase by $3.5 to $4.0 billion.     

Surgery resident selection and evaluation. A critical incident study

This article reports a study of the process of selecting and evaluating general surgery residents. In personnel psychology terms, a job analysis of general surgery was conducted using the Critical Incident Technique (CIT). The researchers collected 235 critical incidents through structured interviews with 10 general surgery faculty members and four senior residents. The researchers then directed the surgeons in a two-step process of sorting the incidents into categories and naming the categories. The final essential categories of behavior to define surgical competence were derived through discussion among the surgeons until a consensus was formed. Those categories are knowledge/self-education, clinical performance, diagnostic skills, surgical skills, communication skills, reliability, integrity, compassion, organization skills, motivation, emotional control, and personal appearance. These categories were then used to develop an interview evaluation form for selection purposes and a performance evaluation form to be used throughout residency training. Thus a continuum of evaluation was established. The categories and critical incidents were also used to structure the interview process, which has demonstrated increased interview validity and reliability in many other studies. A handbook for structuring the interviews faculty members conduct with applicants was written, and an interview training session was held with the faculty. The process of implementation of the structured selection interviews is being documented currently through qualitative research.     

How a CQI program improved aminoglycoside use in a community hospital

The P & T Committee of our institution, a 285-bed, non-tertiary care regional medical center, undertook a study to evaluate the use of the aminoglycoside amikacin sulfate (Amikin). Results of an initial DUE, a follow-up to an educational effort, and the estimated annual cost savings that could be achieved with appropriate prescribing of aminoglycosides are presented.     

Spike voltage topography identifies two types of frontotemporal epileptic foci

We characterized voltage topography of frontotemporal EEG spikes in 24 patients with complex partial seizures and identified two distinct patterns. "Type 1" spikes possessed a "dipolar" field with a negative region over the inferolateral temporal scalp and a positive region over the contralateral, centroparietal scalp. "Type 2" spikes showed only a broad, frontotemporal negative field. One or the other spike type predominated in all but two patients. Correlations with clinical data and intracranial EEG suggest that type 2 spikes arise from temporal or frontal neocortex, while type 1 spikes involve mesial temporal structures as well as lateral cortex.
