Aims: An increase in temperature in an area suspected of septic arthritis is a clinically important finding. The aim of this study is to evaluate temperature changes in septic arthritis with a high-resolution thermal camera. Methods: A total of 49 patients, who were evaluated with a prediagnosis of arthritis (septic or non-septic), were included in this study. A temperature increase in the knee with suspected septic arthritis was evaluated by using thermal imaging and compared with the opposite-side joint. Then, in order to confirm the diagnosis, a culture was taken using routine intra-articular aspiration. Results: The thermal measurements were compared in 15 patients with septic arthritis and 34 patients with non-septic arthritis. The mean temperature was 37.93 °C in the septic group, while it was 36.79 °C in the non-septic group (p < 0.000 *). The mean temperature difference in both joints was 3.40 °C in the septic group, while it was 0.94 °C in the non-septic group (p < 0.000 *). While the mean temperature was 37.10 °C in the group with septic arthritis, it was measured to be 35.89 °C in the group non-septic arthritis (p < 0.020). A very strong positive correlation was found between the difference in the mean temperatures of both groups and the values of the hottest and coldest points (r = 0.960, r = 0.902). Conclusions: In the diagnosis of septic arthritis, thermal imagers can be used as a non-invasive diagnostic tool. A quantitative value can be obtained to indicate to a local temperature increase. In future studies, specially designed thermal devices can be developed for septic arthritis.

Introduction: We present a case series of two patients who underwent plate-assisted bone transport (PABT) with a uniplanar external fixator for the treatment of large bone defects of the humerus. The efficacy and outcomes were evaluated. Case presentation: A retrospective review of patients treated with PABT for humeral defects over a 2-year period was performed. Proper gap healing occurred within 3 months, and a long course of physiotherapy was involved in obtaining satisfactory outcomes. Discussion: Our results demonstrate that PABT might be a potentially effective alternative for large humeral defects, allowing controlled bone lengthening and healing without disrupting vascularity and providing stability for early motion. Conclusion: PABT appears to be a viable option for the management of large humeral defects with good functional outcomes and a manageable complication profile. Highlights:

Introduction and importance: Focal fibrocartilaginous dysplasia (FFCD) is a rare disease of the ulna that requires early surgical intervention. Case presentation: We present a juvenile case and the outcomes of a corrected deformity. The fibrotic band that adhered to the ulna was resected, the ulna was osteotomized, and then an external fixator was placed for lengthening. The ulna's distal physis line was extended by 18 mm so that it would be the same length as the distal physis line of the radius. Full functional recovery occurred within three months. Clinical discussion: There have been 22 cases of ulnar FFCD reported in the literature. Our patient is the oldest reported thus far who developed radial head subluxation, but no dislocation occurred. Conclusion: FFCD is a broad-spectrum disease. Although its course is generally poor for patients with a late diagnosis, it is possible to obtain good results with correction procedures. Highlights:

Background/Aim: Low back pain (LBP) is a highly prevalent pathology affecting more than half of our population. The lumbar region inherently possesses a complex structure; therefore, dozens of causes for the clinical presentation of acute/chronic pain are present. We focused on the impact of hamstring shortness on LBP in healthcare workers/professionals who need to keep medical records and perform invasive procedures while traveling overwhelming distances in relatively small workplaces. Methods: Our research was designed as a cross-sectional study and was conducted at Beykent University Hospital from March to April 2022. Sixty-two otherwise healthy healthcare workers/professionals aged 25–45 (both male and female) volunteered. Two equal groups with and without LBP were created. Oswestry disability index, Roland–Morris score, Quebec LBP questionnaire, Visual Analog Scale (VAS), active/passive knee extension, sit and reach, and forward bending tests were performed in each group. The collected data were statistically analyzed (confidence interval [CI]=20%; P<0.05). Results: Active/passive knee extension, sit and reach, and toe touch tests were significantly related to Roland–Morris, Quebec, and Oswestry Disability Index questionnaires; thus hamstring muscle shortness was significantly related to chronic low back pain (P<0.05). Short hamstring muscle length could accurately reflect the lower test scores obtained by the female participants. Conclusion: Hamstring muscle shortness could explain a significant proportion of low back pain in healthcare professionals.

Introduction and importance: Hip dislocation remains a significant complication following total hip arthroplasty, even though its incidence has decreased. While closed reduction is typically performed for early dislocations, delayed or chronic dislocations often necessitate acetabular or femoral component revision. Case presentation: This document describes the treatment of hip dislocation in a 56-year-old patient through pelvic osteotomy without component revision. An acetabular component malposition was identified, exhibiting an 80-degree inclination and 20-degree cup anteversion. Owing to limited bone stock, a modified Stoppa approach was used for pelvic osteotomy to reduce acetabular inclination. The patient displayed remarkable clinical improvement, achieving a Harris Hip Score of 85 at the two-year check-up with no signs of dislocation. Clinical discussion: Recurrent hip dislocation is difficult to manage. It frequently necessitates component revision, presenting a challenge due to issues with cup extraction and limited bone stock. Preoperative detection of loosened components is crucial. If it goes undetected, the extraction process can result in bone loss, potentially leading to pelvic insufficiency. Conclusion: Successful revisions of hip arthroplasties can be achieved with geometric modifications to the pelvis. Highlights:
