Management of rotational malalignment following operative treatment of fractures of the lower extremities. A scoping review.

BACKGROUND: Rotational malalignment after operative fracture treatment of the lower extremity may be associated with increased pain and functional impairment. Despite its clinical relevance, there are no uniform management guidelines. The aim of this scoping review is to provide an overview of all available evidence to diagnose and treat rotational deformities of the lower extremity following operative fracture treatment. METHODS: This scoping review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A literature search was carried out on 22 August 2023 by two independent reviewers in the Pubmed (MEDLINE), Embase, Web of Science, and Cochrane library databases. The search strategy was developed with the assistance of a biomedical information specialist. The main search terms were tibial and femoral malrotations. Disagreements were resolved through discussion with a third reviewer. RESULTS: After screening and quality assessment of 3929 unique identified records, 50 articles were included for qualitative synthesis. Most studies were retrospective case reports or case series. Thirty studies focused on the femur, 11 on the tibia and nine included both femur and tibia. Most of the included studies presented cases where malrotation was associated with other limb deformities. Only 18 studies focused solely on the treatment of malrotation of the lower extremities after operative fracture treatment. Regarding diagnosis, bilateral CT-scans were used in 34 studies. Regarding treatment, external fixation was used in two studies, internal fixation (either intramedullary nail or plate) in 45 studies, and in three studies the authors used both. Overall, revision surgery resulted in good clinical outcomes with low complication rates. CONCLUSION: This scoping review reveals that rotational malalignment following operative treatment of lower extremity fractures remains an important complication. Although it occurs frequently and is associated with severe disability for the patient, standardized guidelines regarding the terminology, diagnosis, indications for intervention and treatment are lacking. CT-scan is the most used diagnostic modality in daily clinical practice. Revision surgery, using diverse operative techniques, demonstrated positive results, significantly alleviating patient complaints with few complications. Nevertheless, an international consensus regarding the optimal management pathway is needed, and future prospective clinical studies seem therefore necessary.

Validity of Routinely Reported Rutherford Scores Reported by Clinicians as Part of Daily Clinical Practice.

Routinely reported structured data from the electronic health record (EHR) are frequently used for secondary purposes. However, it is unknown how valid routinely reported data are for reuse. This study aimed to assess the validity of routinely reported Rutherford scores by clinicians as an indicator for the validity of structured data in the EHR. This observational study compared clinician-reported Rutherford scores with medical record review Rutherford scores for all visits at the vascular surgery department between April 1, 2016 and December 31, 2018. Free-text fields with clinical information for all visits were extracted for the assignment of the medical record review Rutherford score, after which the agreement with the clinician-reported Rutherford score was assessed using Fleiss' Kappa. A total of 6,633 visits were included for medical record review. Substantial agreement was shown between clinician-reported Rutherford scores and medical record review Rutherford scores for the left ( k = 0.62, confidence interval [CI]: 0.60-0.63) and right leg ( k = 0.62, CI: 0.60-0.64). This increased to the almost perfect agreement for left ( k = 0.84, CI: 0.82-0.86) and right leg ( k = 0.85, CI: 0.83-0.87), when excluding missing clinician-reported Rutherford scores. Expert's judgment was rarely required to be the deciding factor (11 out of 6,633). Substantial agreement between clinician-reported Rutherford scores and medical record review Rutherford scores was found, which could be an indicator for the validity of routinely reported data. Depending on its purpose, the secondary use of routinely collected Rutherford scores is a viable option.

Bilateral kidney metastases from adenoid cystic carcinoma of lung: a case report and literature review.

Adenoid cystic carcinoma (ACC) is a rare malignant tumor, usually arising from salivary glands and rarely found in other locations. ACC is characterized by asymptomatic course, slow growth pattern, perineural invasion and high incidence of late metastasis. Renal localization of metastasis is rare. Only 12 cases of renal metastasis were published and, to our best knowledge, no case of bilateral metastasis to the kidney has ever been reported. We present a case of a 58 years old woman with bilateral renal metastasis from ACC of the right lung after fourteen years from lobectomy and radiotherapy for the primary presentation. The patient underwent bilateral robot-assisted partial nephrectomy in a two-stage approach. Despite its rare incidence and slow growth, ACC metastasis may simulate primary papillary renal carcinoma and occur many years after primary treatment. Therefore, lifelong follow-up, including abdominal imaging, is recommended.
