Cobb Angle Pro combines two focused clinical measurement workspaces: Cobb angle tools for spine X-rays and a digital goniometer for joint range of motion. For spinal images, place Cobb landmarks manually, review AI-assisted landmark suggestions, check sagittal vertical axis alignment, and organize local case records. Export annotated PDF or JPEG reports when a measurement is ready. For range of motion, measure from an existing photo, capture a new image with the camera, or use the iPhone motion sensor as a live goniometer. Set a neutral position, watch the live angle, and capture a stable reading manually or with auto capture. Built for structured measurement workflows: - Cobb angle measurement on imported spine X-rays - AI-assisted Cobb landmark suggestions for user review - SVA alignment tools and multi-curve documentation - Digital goniometer for joint range of motion - Photo, camera, and live sensor measurement modes - Shoulder, elbow, wrist, hip, knee, ankle, and spine movement records - Patient history and ROM trends by side, body part, and movement - Annotated PDF and JPEG exports Cobb Angle Pro is a measurement and documentation aid. It does not diagnose disease, recommend treatment, replace professional judgment, or provide emergency medical advice. Verify every measurement before clinical use.

About

Skeletal Plan

Features
Read full description

Skeletal Plan is a pre-operative planning and documentation aid for spine surgeons. Plan the construct, scan the implants you use, and keep a structured operative record. It runs entirely on your device and works offline. PLAN Design the construct level by level across the whole spine: pedicle and lateral-mass screws, hooks, rods, interbody and corpectomy cages, plates, osteotomies (Schwab 1 to 6) and correction forces. Work on normal anatomy or anatomical variants such as transitional lumbosacral levels. Population-based reference dimensions from the published adult morphometry literature help you start from a sensible size, which you then verify against the patient's own imaging. SCAN, OR JUST RECORD Record the implants actually used. Scan the barcode on the packaging to auto-fill the manufacturer, system, size, lot number and expiry date, or enter the sizes by hand when screws arrive on a non-sterile tray with nothing to scan. The scanner reads GS1 DataMatrix, GS1-128 and two-part HIBC labels and matches them against a curated catalogue of more than 90,000 implant references. KEEP Keep a clean record that stays useful long after the case: - A PDF for the patient record and operative notes - An implant inventory for stock and cost - Lot and expiry traceability for audit - Structured data for research PRIVATE BY DESIGN Skeletal Plan has no servers, no accounts, no analytics and no advertising. Everything you enter, including any patient information, stays on your device, encrypted at rest, and is never sent to us or anyone else. Session privacy is on by default, so nothing is stored unless you choose to save it. You decide if and where a plan is ever shared. WORKS ANYWHERE Designed for theatre: a tablet at the planning station or a phone in your pocket, with the same app on a desktop or laptop web browser. All resources are bundled in the app, so it keeps working with no network. Available in 22 languages, including right-to-left scripts (Arabic, Hebrew) and Chinese, Japanese and Korean. FREE FOR CLINICAL USE Free for clinical planning, intra-operative documentation, teaching and research. IMPORTANT Skeletal Plan is a documentation and communication aid for surgical planning. It is not a medical device and has not been approved, cleared or certified by any regulatory body. Population-based reference data represents group averages; individual anatomy varies, and the operating surgeon must verify all dimensions against the patient's own imaging and bears full responsibility for all clinical decisions and for verification at the point of use.
