Gluteal compartment syndrome secondary to prolonged immobilization following carbon monoxide poisoning associated with leukoencephalopathy: A case report.

Introduction: Gluteal compartment syndrome (GCS) is a rare diagnosis that results mostly from a non-traumatic etiology. We describe a case of a gluteal compartment syndrome, complicated with sciatic nerve palsy. Case presentation: This paper reported a case of gluteal compartment syndrome caused by prolonged immobilization due to carbon monoxide poisoning. The case was complicated with sciatic nerve palsy and a sequala of leukoencephalopathy. Discussion and conclusion: This case report highlighted the importance of having a high suspicion for gluteal compartment syndrome in patients with history of lying down with prolonged immobilization. The diagnosis can be made solely on clinical examination and a fasciotomy must be performed with no delay.

Comparison of Dynamic Hip Screw and Proximal Femoral Nailing Techniques in Stable Intertrochanteric Fractures.

Introduction Dynamic Hip Screw (DHS) and Proximal Femoral Nail (PFN) are two well-accepted modes of surgical treatments for intertrochanteric (IT) hip fractures. While studies have extensively explored the efficacy of one over the other in unstable fractures, the comparison is sparsely available for stable fractures. The main aim of this study is to compare DHS or PFN corrective surgeries in cases of stable IT fractures operated at the Hamad General Hospital, Doha, Qatar, between 2016 and 2018. Methods We conducted a retrospective data review of all stable IT fractures operated at the Hamad General Hospital, Doha, Qatar, between 2016 and 2018. Data were extracted from electronic medical CERNER records, including demographics, clinical notes, operative reports, radiographs, and imaging reports. Data review was followed by prospective data collection via phone about the current post-operative functional status of all cases. Data analysis was done on SPSS v.23. Study was approved by Medical Research Center (MRC) and Institutional Review Board (IRB) at Hamad Medical Corporation (HMC). Study Protocol ID: MRC-01-19-108 Results Out of 62 stable IT fractures operated at our center during the study period, 42 underwent DHS correction, while 20 had PFN. The mean age of the studied cohort was 66.56 years (± 15.95). Males were twice more than females. The mean duration of surgery was 83.73 minutes for DHS and 120.25 minutes for PFN. This difference was statistically significant (p < 0.001). Differences in intraoperative blood loss, duration between fracture and surgery, and length of hospital stay were all statistically insignificant. Patients who underwent PFN showed a higher frequency of return to ambulation (assisted and unassisted), while the number of patients with DHS was less for the functional outcome. Similarly, more post-PFN radiographs displayed union than post-DHS radiographs (55% and 38%, respectively). This difference was statistically insignificant. Conclusion Our study showed promising results for stable IT fractures treated with PFN. However, more data and prospective observational studies are required to establish more statistically significant results.

Edema of the Ligamentum Teres as a Novel MRI Marker for Non-Traumatic Painful Hip Pathology: A Retrospective Observational Study.

Background The ligamentum teres has been recognized as an important stabilizer of the hip joint and can be affected by various hip pathologies. This study aims to introduce ligamentum teres edema as an MRI marker to diagnose the underlying cause of hip pathology, mainly femoral acetabular impingement (FAI) and adult developmental dysplasia of the hip (ADDH), in non-traumatic patients. Methodology Adult patients presenting with non-traumatic hip pain of variable duration and ligamentum teres edema on MRI between 2014 and 2020 were included. A high-resolution standard MRI hip protocol was used for all patients in this series. MRI and plain radiographs were assessed. Ligamentum teres edema, alpha angle, center edge angle of Wiberg, and retroversion were assessed. Results In total, 55 patients with 110 hip joints (males: 29 (52.7%), females: 26 (47.3%)) of different ethnicities were included in this study. Out of the 55 patients with ligamentum teres edema, one had only unilateral right-sided FAI, seven had only unilateral left-sided FAI, and 46 (94 hip joints) had either bilateral FAI or ADDH. Therefore, eight (14.5%) patients with unilateral FAI had the absence of the contralateral FAI or ADDH (6.5% false-positive) despite the presence of ligamentum teres edema bilaterally, and the rest of the patients with bilateral ligamentum teres edema (102 joints: 92.7% positive predictive value) had findings of either FAI or ADDH. Conclusions Ligamentum teres edema can be considered as an early MRI marker to diagnose the underlying pathology of symptomatic painful hip disorders, especially FAI.
