Medial malleolus screws: out in one view and out.

Cartilage damage or mechanical blocking from screw penetration into intra-articular cartilage can reduce the chances of successful outcomes during medial malleolus fixation. There have been diverging opinions among surgeons concerning the reliability of radiographic assessment of fracture fixation and malleolus screw positioning. Therefore, this radiographic study examines the location of medial malleolus lag screws relative to the ankle mortise articular surface. In three Sawbones models, Kirschner wires were overdrilled with a 4.0-mm cannulated cortical screw simulating screws that would be intra- and extra-articular when performing open reduction and internal fixation of a medial malleolar fracture. Under fluoroscopy, images were evaluated to determine whether known intra-articular screws appeared extra-articular in any radiographic view. No image from models with known intra-articular penetration appeared extra-articular in any view or under "live" fluoroscopy. At 20° internal rotation, a screw with a known extra-articular position appeared to be within the cartilage. Intra-operative fluoroscopy is necessary to ensure proper extra-articular placement of screws. If a screw is pictured extra-articular in any radiograph, then it can be assumed that the screw is indeed out of the joint.

International knee documentation committee knee survey use after anterior cruciate ligament reconstruction: a 2005-2012 systematic review and world region comparison.

PURPOSE: The purpose of this review was to evaluate International Knee Documentation Committee (IKDC) survey use after anterior cruciate ligament reconstruction compared with other surveys and determine evidence levels and methodologic study quality by world region. METHODS: The Medline database was searched from January 2005 through December 2012. RESULTS: We identified 421 studies and 33 surveys. Europe and Australia had more objective and subjective IKDC form use (χ(2) = 9.6, P = .047). Europe and Asia had more objective IKDC form use (χ(2) = 19.4, P = .001). Asia had more Lysholm knee scale use (χ(2) = 29.9, P < .0001). Europe had more Tegner Activity Level scale (χ(2) = 31.7, P < .0001) and Knee Injury and Osteoarthritis Outcome Score (χ(2) = 20.5, P < .0001) use. North America and Australia had more Cincinnati or Noyes knee rating scale use (χ(2) = 21, P < .0001). Asia and Australia had more studies with greater than 60 subjects (χ(2) = 24.4, P = .018). Europe had more studies with greater than 24 months' follow-up (χ(2) = 18.4, P = .018). Asia had more studies with adequate surgical descriptions (χ(2) = 33.2, P < .0001). North America had more studies with well-described rehabilitation (χ(2) = 18.2, P = .02). Europe had more studies with confirmed recruitment (χ(2) = 12.9, P = .012). Australia and North America had more studies with confirmed independent investigators (χ(2) = 11.1, P = .026). Europe had more studies with greater than 80% recruitment (χ(2) = 16.0, P = .04). Methodologically stronger studies used the objective IKDC survey (P < .0001), the objective and subjective IKDC survey (P = .002), or the Cincinnati or Noyes scale (P = .002). This group also made greater use of the Tegner scale (P = .013). CONCLUSIONS: Objective and subjective IKDC form use is comparable with Lysholm and Tegner scale use. Objective and subjective IKDC form use in combination with the Tegner Activity Level scale is recommended. LEVEL OF EVIDENCE: Level IV, systematic review of Level I-IV studies.

Repeat Irrigation and Debridement of Upper Extremity Infections: Do Repeat Cultures Change Antibiotic Treatment Regimens?

BACKGROUND: Organism identification and their antibiotic sensitivity profile are critical for the successful treatment of upper extremity infections. Although many infections resolve with antibiotics alone, some require 1 or more surgical procedures in which culture data are obtained. The purpose of this study was to determine whether repeat cultures taken at subsequent irrigation and debridement of upper extremity infections changed antibiotic treatment. METHODS: A retrospective review was performed using International Classification of Diseases, Ninth Revision codes to identify all adult patients with an upper extremity infection treated with 2 irrigation and debridement procedures with 2 separate culture data sets over a period of 5 years. Culture organisms and antibiotic sensitivity profiles were compared from each procedure, and changes in antibiotic treatment based on repeat culture information were identified. RESULTS: In all, 183 patients who underwent 2 irrigation and debridement procedures with repeat culture data were identified. Organisms identified with repeat culture were the same or there was no growth in 153 patients and were different in 30 patients. The antibiotic treatment did not require a change in 170 (92.9%) of 183 patients. Of the 30 patients with different repeat cultures, antibiotic treatment changed in only 13 patients (43.3%). Patients who had a change in antibiotic treatment were more likely to have hepatitis C (P = .005). CONCLUSIONS: Repeat culture data changed antibiotic treatment in only 7.1% of patients from our cohort. Patients with hepatitis C were more likely to require a change in antibiotic management after obtaining repeat cultures.

Ultrasound Cross-Sectional Area of the Median Nerve Is Not a Predictor of Patient Reported Outcomes After Carpal Tunnel Release.

BACKGROUND: The purpose of this study was to evaluate the relationship between cross sectional area (CSA) of the median nerve on ultrasound (US) with pre- and postoperative Boston Carpal Tunnel Questionnaire (BCTQ) scores. We hypothesize that there is a positive correlation between CSA and the ΔBCTQ after carpal tunnel release (CTR). METHODS: This was a single center study. During a 6-year period (2014-2020), CSA of the median nerve on US and BCTQ scores were collected prospectively for patients presenting with the chief complaint of numbness and tingling in the upper extremity. Patients who underwent CTR and presented for their 6-week follow-up had repeat measurements of the CSA and BCTQ. These patients were included in this study. Patients were then divided into ultrasound positive (CSA ≥ 10) and ultrasound negative (CSA < 10) groups. These groups were compared on the basis of demographics, preoperative BCTQ scores, postoperative BCTQ scores, and 6-week ΔBCTQ score. RESULTS: US-positive and-negative groups did not differ significantly in their preoperative BCTQ, postoperative BCTQ, or ΔBCTQ scores. Both groups did, however, experience significant improvement when comparing preoperative to postoperative BCTQ scores within their respective US group. CONCLUSION: Regardless of the preoperative CSA of the median nerve, patients who underwent CTR experienced a significant improvement in their BCTQ results. US-positive patients experienced no greater improvement than US-negative patients. These results would suggest that US is not a good predictor of subjective surgical outcome measures such as the BCTQ.
