Abstract: background: an incisional lumbar hernia after a flank incision is a problem in hernia surgery. in recent decades preperitoneal prosthetic herniorrhaphy became a widely accepted procedure for abdominal wall hernias, but there are no reports with more than 6 cases. to evaluate outcome and technique of repair the flank hernias we reviewed our data on every patient who underwent this type of repair. methods: we identified 20 patients who underwent hernia repair after incisional or traumatic hernia of the flank within the last 10 years. all the patients were followed in the general surgery service of de iscmpa/ fffcmpa. results: using information from the database, we analyze 20 cases of lumbar hérnia. the majority (19 cases) were incisional hernias, only one was traumatic. the right side was affected in 14 cases and the left in 6 cases. the median followup was 60 months (5-72), although 7 cases have no follow-up. there was no failure during a follow-up 6 months to 8 years. however, one patient remained with weakness on flank, two presented seroma and that varied betwwen one presented wound infection. conclusion: we authors recommend the conventional intervention instead of a laparoscopic one, in which a primary repair was used in cases of diameters up to 5 cm. in case of wider diameters it becomes mandatory to approach borders without tension, otherwise prosthetic material should be adopted.

Abstract: objective: bertolotti's syndrome is a spine disorder characterized by the occurrence of a congenital lumbar transverse mega-apophysis in a transitional vertebral body that usually articulates with the sacrum or the iliac bone. it has been considered a possible cause of low back pain. method: we analyzed the cases of bertolotti's syndrome that failed clinical treatment and reviewed the literature concerning this subject. results: five patients in our series had severe low back pain due to the neo-articulation and two of them were successfully submitted to surgical resection of the transverse mega-apophysis. taking into account the clinical and surgical experience acquired with these cases, we propose a diagnostic-therapeutic algorithm. conclusion: there is still no consensus about the most appropriate therapy for bertolotti's syndrome. in patients in whom the mega-apophysis itself may be the source of back pain, surgical resection may be a safe and effective procedure.

Abstract: Relative flexibility between the hamstring and lumbar extensor muscles, which can be evaluated using lumbopelvic curvature during active knee extension in sitting, can sometimes be assessed in physical therapy. However, reliability for its quantitative measure has not been established yet and its establishment was the aim of the current study. Twenty-seven individuals with clinically tight hamstring muscles were recruited. On two separate sessions, the lumbopelvic curvature was evaluated in sitting when the right knee was moved from 90° flexion to 10° flexion on 15 occasions using a flexible ruler by two examiners on Day 1 and one on Day 2. Lines drawn tangential to the lumbopelvic curvature were traced at T12 and S2 vertebral levels and the angle between the two vertical lines was calculated. Using Day 1 data, the minimum number of repetitions and inter-examiner reliability were assessed. Inter-session reliability was also examined. As a result, there was no statistical difference (P?> 0.05) in the mean absolute difference between the mean value of N-1 and N repetitions (6 ≤ N ≤ 15) in the lumbopelvic curvature angle, indicating that five was considered the minimum number of repetitions. Intraclass correlation coefficient (ICC)(1, 5)?for the inter-session reliability and ICC(2, 5)?for the inter-examiner reliability was 0.97 and 0.93, respectively, indicating excellent reliability. The measure for the lumbopelvic curvature during active knee extension in sitting, which was established in the current study, will be a foundation for further research regarding the relative flexibility of the lumbar and adjunct regions.

Abstract: In a previous study, we established reliability of a method for determining the angle of lumbopelvic sagittal alignment during active knee extension in sitting (AKEiS) using a flexible ruler and image analysis software (2-point-Method). In addition to this method, a flexible ruler can also be used to measure lumbopelvic sagittal alignment without image analysis software. This study primarily aimed to investigate the minimum number of repetitions, inter-session reliability and inter-examiner reliability of two alternative methods of measurement in a secondary analysis of our previous study. A flexible ruler was used to measure lumbopelvic curvature during AKEiS when the knee reached 10° flexion from 27 individuals with clinically tight hamstring muscles and subsequently analyzed. Lumbopelvic sagittal alignment was evaluated for the region between T12 and S2 using the maximum depth to the curvature (Max-Method) or depth to the curvature at the middle point between T12 and S2 vertebral levels (Mid-Method). It was determined that four repetitions for the Max-Method and 11 repetitions for the Mid-Method were required for the minimum number of repetitions, respectively. Inter-session reliability and inter-examiner reliability were assessed using Intraclass Correlation Coefficients and were 0.91 and 0.91 for the Max-Method and 0.90 and 0.91 for the Mid-Method, respectively. The current study suggests that the Mid-Method would not be recommended for use in the clinical setting as 11 repetitions of data sampling is required. The 2-point-Method or Max-Method may be promising but the ideal measurement method will be identified when the validity of these methods has been established.
