Nonunion of an Undisplaced Lateral Compression Type 1 Pelvic Ring Fracture due to Interposition of a Tension-Free Vaginal Tape: A case report.

CASE: Nondisplaced lateral compression type 1 fractures of the pelvic ring are usually treated nonoperatively. We describe a case of nonunion after conservative treatment of such a fracture in a healthy 59-year-old female patient due to the interposition of a tension-free vaginal tape in the fracture gap. An anterior intrapelvic approach with plate osteosynthesis was used to stabilize the fracture once the tape was removed from the fracture gap. After 3 months, the fractures had healed and the patient was pain-free. CONCLUSIONS: Previous urogynecologic interventions should be routinely inquired about and considered in anterior pelvic ring injuries.

Reliability and Reproducibility of a Novel Grading System for Lesions of the Ligamentous-Fossa-Foveolar Complex in Young Patients Undergoing Open Hip Preservation Surgery.

Background: Several classification systems based on arthroscopy have been used to describe lesions of the ligamentum teres (LT) in young active patients undergoing hip-preserving surgery. Inspection of the LT and associated lesions of the adjuvant fovea capitis and acetabular fossa is limited when done arthroscopically but is much more thorough during open surgical hip dislocation. Therefore, we propose a novel grading system based on our findings during surgical dislocation comprising the full spectrum of ligamentous-fossa-foveolar complex (LFFC) lesions. Purpose: To determine (1) intraobserver reliability and (2) interobserver reproducibility of our new grading system. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: We performed this validation study on 211 hips (633 images in total) with surgical hip dislocation (2013-2021). We randomly selected 5 images per grade for each LFFC item to achieve an equal representation of all grades (resulting in 75 images). The ligament, fossa, and fovea were subcategorized into normal, inflammation, degeneration, partial, and complete defects. All surgeries were performed in a standardized way by a single surgeon. The femur was disarticulated using a bone hook, the LT was inspected, documented and resected, then the fossa and fovea were documented with the femoral head in full dislocation using a 70° arthroscope. Six observers with different levels of expertise in hip-preserving surgery independently conducted the measurements twice, and intraclass correlation coefficients (ICC) were calculated to determine (1) intraobserver reliability and (2) interobserver reproducibility of the novel grading system. Results: For intraobserver reliability, excellent ICCs were found in both the junior and the experienced raters for grading the ligament, fossa, fovea, and total LFFC (ICCs ranged from 0.91 to 0.99 for the LFFC score). We found excellent interobserver reproducibility between raters for all items of the LFFC (all interobserver ICCs ≥ 0.76). Conclusion: Our new grading system for lesions of the LFFC is highly reliable and reproducible. It covers the full spectrum of damage more precisely than arthroscopic classifications do and offers a scientific basis for standardized intraoperative evaluation.

The first 100 elbow arthroscopies of one surgeon: analysis of complications.

BACKGROUND: Elbow arthroscopy is technically challenging and prone to complications especially due to the close relation of nerves and vessels. Complication rates up to 20% are reported, depending on indication and how complications are defined. This study analyzes the complications of the first 100 elbow arthroscopies done by 1 fellowship- and cadaver-trained surgeon. MATERIALS AND METHODS: From September 2004 to April 2009, 100 consecutive elbow arthroscopies were performed, and thus consequently standardized, by 1 surgeon in 1 institution. The clinical data of all patients were retrospectively analyzed for indication-specific complications. Complications were divided into minor (transient) and major (persistent or infection). RESULTS: Included were 65 male and 35 female patients (mean age, 41 years; range, 12-70 years) with a minimum follow-up of 12 months (clinical or telephone). The following indications were documented (several per patient were possible): osteoarthritis in 29, stiffness in 27, loose bodies in 27, tennis elbow in 24, traumatic sequelae in 19, and others in 24. No major complications occurred, but 6 minor complications occurred in 5 patients (5%), comprising 2 hematoma, 2 transient nerve lesions, 1 wound-healing problem, and 1 complex regional pain syndrome. No revision surgery was necessary. Complications were not significantly associated with the indication for operation or the surgeon's learning curve. CONCLUSION: This study shows an acceptable complication rate of the first 100 elbow arthroscopies from a single surgeon. A profound clinical education, including cadaver training as well as standardization of patient position, portals, and surgery, help to achieve this.
