Foot and Ankle Surgery最新文献

Background: A peroneus longus to brevis tendon transfer is recommended for a severely torn peroneus tendon, but there is little research on the outcome. We conducted a prospective cohort study to examine patient-reported outcomes after this procedure.

Methods: Thirty-two patients underwent a peroneus longus to brevis tendon transfer and lateral ankle ligament reconstruction, 11 had an additional calcaneal osteotomy. The Foot and Ankle Outcome Score (FAOS) and Short Form-36 (SF-36) were assessed preoperatively, six and 12 months after surgery.

Results: Preoperative mean FAOS was 51.7 (SD 17.8) compared with 72.7 (SD 21.2) at 12 months, an improvement of 21 (95 % CI 12.7-28.0) (p < 0.0001). SF-36 improved significantly in the three domains involving physical function and bodily pain (p < 0.007).

Conclusion: Patient-reported outcomes improved significantly through peroneus longus to brevis tendon transfer. This procedure is worth considering for patients with a severely damaged peroneus tendon.

Level of evidence: Level II: Prospective cohort study.

Background: This study evaluated the ability to differentiate between AI-generated and human-authored abstracts in foot and ankle surgery.

Methods: An AI system (ChatGPT 3.0) was trained on 21 published abstracts to create six novel case abstracts. Nine foot and ankle surgeons participated in a blinded survey, tasked with distinguishing AI-generated from human-written abstracts, rating their confidence in their responses. Surveys were completed twice at two different time points to evaluate intra-/inter-observer reliability.

Results: The overall accuracy rate for distinguishing AI-generated from human-written abstracts was 50.5 % (n = 109/216), indicating no better performance than random chance. Reviewer experience and AI familiarity did not significantly affect accuracy. Inter-rater reliability was moderate initially but decreased over time, and intra-rater reliability was poor.

Conclusions: In their current form, AI-generated abstracts are nearly indistinguishable from human-written ones, posing challenges for consistent identification in foot and ankle surgery.

Level of evidence: IV.

Background: Traditional imaging techniques for total ankle arthroplasty (TAA) evaluation are limited by rotational bias and bone superimposition, highlighting the necessity for more precise assessment methods. The advent of weight-bearing computed tomography (WBCT) generated 3D enhance the visualization of foot and ankle alignment, offering unmatched detail. This study aims to assess the accuracy of preoperative and postoperative measurements in TAA across all three planes using WBCT-generated 3D models. We hypothesize that these models can be reliably used to compare preoperative and postoperative alignment.

Methods: For 81 patients undergoing TAA, preoperative and postoperative WBCT models were created. Measurements included five coronal angles: Alpha, Tibiotalar Surface Angle (TSA), Talar Tilt Angle (TT), Salzmann's 20 degrees Angle (SA), and Talocalcaneal Angle (TCA); three sagittal angles: Beta, Gamma, and Tibiotalar Ratio (TTR); and one axial angle: The Posterior Talar Rotational Angle (PTARA). Two raters evaluated these before and after surgery in two separate sessions. The study then compared preoperative to postoperative measurements, calculating inter-rater and intra-rater reliability.

Results: Significant changes were observed in three coronal angles (TSA, TT, and SA) and two sagittal angles (Beta and Gamma), with P-values of 0.2, 0.007, 0.019, <0.001, and <0.001, respectively. No significant changes were noted in Alpha, TCA, TTR, and PTARA, with P-values of 0.2, 0.9, 0.2, and 0.6, respectively. Intra-rater and inter-rater reliability scores ranged from 0.885 to 0.97, indicating good to excellent interclass correlation across all planes, both pre-and postoperatively.

Conclusion: WBCT-generated 3D modeling and image analysis software have enabled a detailed comparison between preoperative alignment and postoperative TAA positioning across coronal, sagittal, and axial planes, revealing significant adjustments in coronal and sagittal alignments. The high reliability and reproducibility of these measurements affirm their value in preoperative planning in improving the accuracy of surgical interventions.

Background: Literature regarding the feasibility of inexperienced surgeons using needle arthroscopy is limited. The present study aimed to clarify the feasibility of performing ankle needle arthroscopy for inexperienced surgeons.

Methods: Diagnostic needle arthroscopy was performed for 10 cadaveric ankles by two surgeons with different levels of experience in ankle arthroscopy (inexperienced and expert surgeons). The visibility of arthroscopy was assessed based on a 15-point checklist and compared between surgeons. In addition, iatrogenic articular cartilage injury created by the inexperienced surgeon was investigated.

Results: The number of visible points was significantly larger for the expert surgeon than for the inexperienced surgeon (14.1 ± 1.0 vs. 13.7 ± 1.0, P = 0.035). The location of cartilage injury was greatest on the medial talar dome when viewing from the anteromedial portal at a rate of 30%.

Conclusion: Ankle needle arthroscopy may be an option for surgeons in the future, however, differences in surgeon experience may impact effective visualization.

Background: Various fixation methods have been described for Akin osteotomy, based on using metal implants or transosseous sutures. The aim of this study was to evaluate radiological outcomes and complications of closing wedge Akin osteotomy based on a crossed suture configuration of the joint capsule rather than using implants. The null hypothesis is that a crossed suture has comparable radiological results to other techniques, with no additional complications.

Methods: It's a retrospective study. Patients who underwent Akin osteotomy fixed either with implant or joint capsule suture between 2015 and 2018 were included. Distal articular set angle corrections in pre- and postoperative anteroposterior foot x-rays were calculated by 2 observers. Complications, such as pain, infection, non-union and need of surgery revision, was compared at 1 year follow-up.

Results: 89 patients, 30 in the implant group and 59 in the suture group. Mean distal articular set angle corrections were 6.43 (SD 5.54) and 7.36 (SD 5.48) degrees in the implant and suture groups, respectively, without statistically significant differences (p 0454). Complications were 2 local pain and 1 wound infection cases in the suture and implant groups, respectively (p 0138, p 0197).

Conclusion: Akin osteotomy with suture fixation yields comparable radiological results to metal implant fixation methods without increasing the associated complications.
