Unveiling the spiral groove: a journey through clinical anatomy, pathology, and imaging.

AIM: To review the anatomy of the spiral groove, its clinical significance, and the imaging characteristics of common pathologies affecting this area, highlighting the strengths of different imaging modalities. MATERIALS AND METHODS: A comprehensive review of the spiral groove anatomy and its clinical implications and an evaluation of various imaging techniques, including radiography, ultrasound, MRI, and CT, was conducted. The review covers pathologic conditions such as Saturday night palsy, humeral fractures, tumours, and infections, with an emphasis on their imaging findings and clinical implications. RESULTS: The spiral groove provides a pathway for the radial nerve and the deep brachial artery, both crucial for upper limb function. Each imaging modality offers unique advantages: radiography is useful for initial assessment, ultrasound provides dynamic visualisation, MRI offers high-resolution soft tissue imaging, and CT is ideal for detailed bone anatomy. Understanding these imaging characteristics is essential for diagnosing fractures, assessing humeral alignment, and detecting nerve entrapment or injury. CONCLUSION: Accurate imaging of the spiral groove is essential for diagnosing and treating pathologies related to this anatomical feature. The integrative approach of using appropriate imaging modalities enhances diagnostic precision and informs therapeutic strategies, ultimately improving patient outcomes.

Right-sided meralgia paresthetica from lateral femoral cutaneous nerve neuroma.

Meralgia Paresthetica (MP) causes outer thigh discomfort, numbness, and tingling. Compression or injury to the Lateral Femoral Cutaneous Nerve (LFCN), which gives sensory innervation to outer aspect of the thigh. It frequently gets impinged beneath the inguinal ligament resulting in in sensory impairment in the distribution of LFCN. Compression of the LFCN is a frequent cause of MP, whereas LFCN neuromas is a rare cause. This case report describes a unique case of Meralgia Paresthetica produced by a LFCN neuroma and enhances our knowledge of Meralgia Paresthetica.

Isolated spontaneous non-insertional tear of the iliopsoas tendon in an elderly patient: significance of ultrasound imaging.

Isolated spontaneous tears in the non-insertional portion of the iliopsoas tendon without any underlying injury are uncommon, especially among elderly individuals. We describe the case of an 88-year-old man who experienced right groin pain caused by a spontaneous non-insertional tear in the iliopsoas tendon identified through ultrasound and confirmed via MRI. Ultrasound revealed hypoechogenicity in the non-insertional portion of the iliopsoas tendon, leading to quick identification and conservative treatment and resulting in positive functional outcomes. This case report emphasises the significance of considering spontaneous non-insertional iliopsoas tendon tears when evaluating cases of acute groin pain. This finding underscores the effectiveness of ultrasound as an initial diagnostic tool for the early cost-effective diagnosis of soft tissue injuries around the hip joint, especially in low-resource settings. Timely detection and management can help avoid unnecessary operative interventions and facilitate faster and better recovery.

Intra-articular Lipoma of the Pisotriquetral Joint: A Rare Case Report.

Intra-articular lipomas are infrequently reported, with most reported cases occurring in the knee joint. A case of intra-articular lipoma in the small joints of the hand, specifically in the pisotriquetral joint, has been documented for the first time. A 24-year-old male visited the emergency department after a road traffic accident with a painful and swollen wrist. Radiographic examination revealed fractures of the distal radius and triquetrum. A subsequent wrist computed tomography scan identified an intra-articular lipoma within the pisotriquetral joint, further confirmed by ultrasonography. This article underscores the importance of recognizing that, though exceedingly rare, intra-articular lipomas should be considered in the differential diagnosis of soft-tissue tumors affecting the hand and wrist.

GIBPS technique-a novel sequential technique of performing shoulder corticosteroid injections.

The introduction of the xxxxxxxx (GIBPS) technique represents a patient-centric novel and innovative method of ultrasound guided corticosteroid injection targeting the Glenohumeral joint (GHJ) and the Subacromial-Subdeltoid (SASD) bursa in a sequential manner, in the same setting. By integrating the two different sites of injection into a single technique, the procedure has the potential of transforming musculoskeletal interventional radiology and maximising patient care in shoulder pathologies. This procedure aims to reduce patient discomfort, optimise procedural efficiency, and enhance treatment precision through ultrasound guidance and improve the overall patient experience.
