This diagnostic image is a midline sagittal computerized tomography (CT) scan of the lower spine and pelvic region, focusing on the sacrococcygeal anatomy. The image demonstrates the curvature of the sacrum and the articulated segments of the coccyx. A prominent white arrow indicates a coccygeal spicule, which is a small, pointed, bony outgrowth with high radiodensity located at the distal tip of the terminal coccygeal segment. Surrounding soft tissue structures, including the rectum and pelvic floor musculature, are visible anterior to the bony column with lower attenuation values. This CT finding is clinically relevant in the evaluation of coccydynia, as a spicule can cause irritation of the overlying skin or subcutaneous tissues during sitting. The image serves as a teaching tool for recognizing morphological variations in coccygeal anatomy and identifying specific causes of idiopathic tailbone pain.

This diagnostic image is a lateral plain radiograph of the sacrococcygeal region of the human spine. The image displays the lower sacral vertebrae and the articulating coccygeal segments. A yellow arrow points specifically to the sacrococcygeal junction, highlighting a ventral (anterior) subluxation of the coccyx. The coccygeal segments are displaced forward relative to the distal sacrum, indicating a disruption of the normal pelvic curve. This radiological finding is clinically significant for the diagnosis of coccydynia (tailbone pain), which may be associated with postpartum trauma or direct injury. The image serves as an educational example of sacrococcygeal malalignment and traumatic orthopedic displacement in a clinical setting.

**Imaging Modality:** Conventional Radiography (X-ray). **Anatomical Region:** Lower pelvic region focusing on the sacrum and coccyx. **View:** Lateral projection. **Description of Findings:** The image displays the terminal portion of the spinal column. The sacrum is visible superiorly, articulating with the coccygeal segments. The coccyx demonstrates an anteverted morphology, characterized by an exaggerated anterior angulation relative to the sacral axis. The coccygeal segments appear intact without definitive evidence of acute cortical disruption or displaced fracture lines visible in this projection. The sacrococcygeal and intercoccygeal joints are visualized, with the distal-most segments curved sharply forward toward the pelvic cavity. **Characteristic Visual Features:** * Increased anterior curvature of the coccyx (antiversion). * Visualization of distinct coccygeal vertebrae and distal sacral segments. * Lateral orientation providing clear assessment of sagittal alignment. **Clinical Context/Diagnostic Utility:** This radiographic finding is indicative of an anatomical variation or positional change of the coccyx. It is a key diagnostic feature used in the evaluation of coccydynia (tailbone pain) to assess for morphological abnormalities, subluxation, or hypermobility that may contribute to clinical symptoms.

This diagnostic image is a lateral fluoroscopic view of the sacrococcygeal region, demonstrating the procedure for an impar ganglion block. The image shows the bony anatomy of the distal sacrum and coccyx. A thin, radiopaque 22-gauge needle is visible (indicated by a white arrow) inserted through the sacrococcygeal junction. The needle tip is positioned in the retrorectal space, immediately anterior to the sacrococcygeal joint. A dark, radiopaque contrast agent (indicated by a black arrow) is seen spreading along the anterior aspect of the coccyx, forming a characteristic 'comma' shape that confirms the correct retroperitoneal placement of the needle for the sympathetic block. This procedure is clinically relevant for managing chronic perineal or pelvic pain. The image serves as an educational example of real-time imaging guidance for precise interventional pain management in anesthesiology and radiology.

This lateral proctography image (defecography) demonstrates a contrast-filled rectum and anal canal. The radiopaque contrast medium highlights the internal morphology of the pelvic floor, revealing a significant anterior outpouching of the rectal wall consistent with a rectocele. The rectal lumen appears distended, with visible irregularities in the mucosal contour and a narrowing distal to the rectocele. An opacified catheter is visible, likely used for contrast administration. Surrounding anatomical landmarks include the bony pelvis, specifically the sacrum, coccyx, and pubic symphysis, which are visible as high-density structures providing spatial orientation. Clinically, this imaging modality is used to evaluate pelvic floor dysfunction, including obstructed defecation syndrome, rectal prolapse, and the anatomical relationship between the rectum and the vaginal wall during straining. The presence of the large rectocele and luminal narrowing provides visual evidence for mechanical causes of chronic constipation and difficult bowel movements.

A multi-panel clinical and diagnostic composite illustrating a minimally invasive surgical fixation of a sacrococcygeal fracture-dislocation. Panels A, C, and D are clinical photographs showing the intraoperative procedure in a patient in the prone position. Panel A demonstrates a small, approximately 1 cm midline incision in the sacrococcygeal region with a surgical needle holder positioned at the entry site. Panel C shows a surgical probe or guide being used to facilitate a subcutaneous figure-of-eight suture technique, while Panel D shows the final tensioning and tying of the non-absorbable suture. Panel B is a lateral fluoroscopic (X-ray) image of the sacrococcygeal spine, showing a radiopaque surgical needle passing intraosseously to bridge the fracture gap between the sacrum and the displaced coccygeal segments. The composite demonstrates the sequence of a 'mini-open' reduction and internal fixation (ORIF) designed to stabilize the coccyx while minimizing soft tissue trauma.

This clinical photograph captures an intraoperative view of a sacrococcygeal surgical procedure. The patient is in a prone position, and an inverted 'Y'-shaped longitudinal incision has been made extending from the S1 level toward the posterior midline of the coccyx. The surgical field is maintained using several metal retractors, including a Weitlaner-style retractor at the inferior margin, which pull back the skin and subcutaneous fat to expose deeper muscular and fascial layers. The exposed area reveals raw, erythematous tissue and a deep cavity in the sacrococcygeal region, corresponding to the space created during the resection of a sacrococcygeal teratoma (SCT). The surgical approach targets the S3 to S5 laminae, providing access to the anterior sacrum and the retroperitoneal space behind the rectum. Visible landmarks include the incised subcutaneous tissue and the underlying musculature of the gluteal and sacral regions. This image demonstrates the parasacrococcygeal approach for the management of complex pelvic masses.

A therapist is performing a posterior talar glide in a non-weight-bearing position to increase the range of motion for ankle dorsiflexion. The patient is positioned supine on a treatment table. The therapist utilizes a stabilization strap (Mulligan-style belt) looped around their own waist and the patient’s distal tibia/fibula to provide stabilization and traction. The therapist's hands are placed specifically over the anterior aspect of the talus to apply a posterior force, indicated by a black directional arrow. This orthopedic intervention is commonly used in the management of joint stiffness related to conditions like plantar fasciitis, heel spurs, or post-immobilization stiffness. The image illustrates the clinical application of mobilization with movement (MWM) principles within sports medicine and musculoskeletal rehabilitation.

This procedural photograph illustrates a physiotherapist performing a passive joint mobilization technique on a patient's ankle, specifically an anterior-posterior (A-P) glide of the talus. The patient is positioned supine or in long-sitting on a treatment table with the lower limb extended. The clinician demonstrates a manual therapy technique where the left hand stabilizes the calcaneus and posterior ankle, while the right hand is positioned on the anterior aspect of the talus, just distal to the ankle joint line. This specific grip is used to apply Grade III oscillatory movements into resistance, aimed at improving dorsiflexion range of motion following injuries such as ankle sprains or fractures. The image serves as a clinical guide for orthopedic manual therapy, highlighting correct hand placement for mobilizing the talocrural joint.

A series of clinical procedural photographs (A, B, C) demonstrating different manual physical therapy mobilization techniques for the knee joint, integrated with a biomechanical data capture system. In all images, a therapist performs a technique on a patient lying supine on a treatment table, while a researcher records data using a laptop-connected multi-channel analyzer. Panel A shows a physiological tibiofemoral extension technique, where the therapist's mobilizing hand is positioned on the anterior proximal tibia and the stabilizing hand on the posterior calcaneus. Panel B illustrates a physiological tibiofemoral flexion technique, with the mobilizing hand on the anterior distal tibia and the stabilizing hand at the knee. Panel C depicts a medial patellofemoral accessory glide technique, with hands positioned on the proximal tibia and distal femur to apply force to the lateral patella. Crucial to the educational focus is the use of a thin, flexible capacitance-based pressure sensing mat placed between the therapist’s hand and the patient’s skin to measure mobilization force, dosage, and oscillation frequency. This setup demonstrates the quantification of manual therapy grades (e.g., Maitland grades III and IV) for clinical research and educational validation.

This clinical photograph demonstrates a physical therapy session focused on cervical spine joint mobilization. The patient is positioned prone on a purple padded examination table with her head comfortably turned. A therapist is shown at the head of the table applying a manual therapy technique consistent with Maitland's postero-anterior (PA) mobilization. The therapist's hands are placed over the upper cervical region, with the thumbs positioned to apply targeted pressure toward the spinous processes of the cervical vertebrae. The image illustrates the clinical application of manual therapy for musculoskeletal conditions, specifically addressing spinal mobility and pain management in the cervical region. This visual is representative of educational materials for physical therapy, osteopathy, and manual medicine, highlighting proper practitioner hand placement and patient positioning for posterior-to-anterior joint glides.

This procedural photograph demonstrates a postero-anterior (PA) joint mobilization of the lumbar spine, specifically utilizing Maitland's technique. The patient is positioned in a prone orientation on a treatment table. A clinician is shown applying manual therapy to the lumbar region. The clinician's right hand uses a reinforced finger-tip contact (index and middle fingers) to apply a focused, downwards force directly over the spinous process of a target lumbar vertebra. The left hand provides stabilization and counter-pressure on the contralateral side of the lower back/iliac crest area. This technique is commonly used in physical therapy and manual medicine to improve joint mobility, assess segmental irritability, and reduce localized spinal pain. The visual emphasizes the specific hand placement and the vector of force required for effective vertebral mobilization in clinical practice.

This clinical photograph demonstrates a thoracic spine mobilization procedure using Maitland’s manual therapy technique. The patient is positioned prone on a treatment table with the neck rotated laterally and arms relaxed at the sides. A physical therapist is positioned at the patient's side, applying a manual postero-anterior (PA) pressure. The therapist's hands are configured in a specialized grip to target a specific spinous process of the thoracic vertebrae. The contact point is centrally located on the upper back, approximately at the level of the mid-thoracic region. This procedural image illustrates a common orthopedic intervention aimed at increasing joint mobility and reducing localized pain, often utilized in clinical trials for conditions such as fibromyalgia. The visual focus is on the correct hand placement and body mechanics necessary for effective spinal joint mobilization.
