Spontaneous acute forearm compartment syndrome: Case report of a clinical diagnosis with limited imaging options.

Diagnostic radiology is essential for providing targeted management of different diseases. Thus, there has been a dramatic increase in the demand for medical imaging. However, acute compartment syndrome (ACS) is one of the clinical scenarios in which radiology has limited value. The authors report a nontraumatic spontaneous ACS in the forearm of a 56-year-old female. The roles of Ultrasound and MRI, if available, are also illustrated. Limited reports of spontaneous ACS are published in the literature; we hope this case adds to the limited data. Our goal in reporting this case is to improve clinical practice with favorable outcomes for the patients involved globally by alert to the onset of ACS to promote early detection and timely fasciotomy. Also, we aim to increase awareness among physicians and radiologists of the limitations of radiology in specific clinical scenarios. Finally, it may aid in illuminating a possible link between malignant hypertension, spontaneous bleeding/hematoma, and ACS.

Early periprosthetic hip joint infection managed by cementless one-stage revision - a case series.

Background: Early periprosthetic hip joint infection (PJI) is traditionally treated with debridement, antibiotics, and implant retention (DAIR). However, infection control rates after DAIR-treated periprosthetic hip joint infection do not exceed 77 %. Cementless one-stage revision of chronic PJI by the Cementless One-stage Revision of Infected Hip Arthroplasty (CORIHA) protocol has been evaluated positively with a 91 % success rate. We wanted to evaluate the effectiveness of cementless one-stage revision following the CORIHA protocol for early PJI in elective primary total hip arthroplasty, regarding risk of re-operation with exchange of implants. Methods: We identified 18 patients in our center with early ( ≤ 6 -week postoperative) PJI after primary total hip arthroplasty (THA) treated with one-stage cementless revision in the period January 2012-March 2018. Treatment followed the CORIHA protocol. Primary outcome was retention of implants at the most recent follow-up. Patients were followed for a minimum of 3 years. Results: Mean follow-up time was 60 months (39-105). All patients retained their implants, but two required superficial soft tissue debridement due to persistent wound seepage. Conclusion: Cementless one-stage revision appears to be an effective treatment of early PJI after primary THA and at least an equal choice of treatment compared with DAIR. Whether the potential benefit of a lower re-revision rate for postoperative PJI outweighs the increased surgical complexity of the CORIHA procedure needs further evaluation.

Morel-Lavallée lesion. / Morel-Lavallées lesjon.

Background: Knowledge about diagnostics and treatment of chronic Morel-Lavallée lesions is sparse. Material and method: The patient presented is a 65-year-old woman who develops a post-traumatic chronic Morel-Lavallée lesion. The paper describes the course of her treatment including dos and don'ts with reference to literature from a systematic PubMed search. Results and interpretation: The Morel-Lavallée lesion is often missed in the trauma setting during both primary, secondary and tertiary examination, resulting in a chronic lesion. Knowledge of the lesion minimises this risk. The gold standard for diagnosis is magnetic resonance imaging, but ultrasonography may also be used in the acute setting. The chronic lesion can be successfully treated with doxycycline-induced obliteration of the cavity followed by compression treatment for a short period.
