LAMA™
Leg Angle Measurement Assistant
Problems
Leg length differences and alignment problems are widespread, affecting around 70% to 90% of the population [1]. These issues often lead to imbalances, unilateral pain, and can trigger degenerative changes in vital areas like the hips, spine, and knees [2]. The resulting degenerative diseases have seen a significant increase in procedures like total knee replacements, with a doubling in incidence between 2000 and 2016 [3]. Addressing these problems is crucial for overall musculoskeletal health.
Solutions
LAMA™ offers complete automation, reducing the need for manual measurements and ensuring consistently accurate results. It significantly increases efficiency, reducing reading times for full-leg radiographs. Additionally, it maintains a consistent level of precision, comparable to expert readers, and accurately measures leg length discrepancies when compared to expert assessments.
Precise
Deep learning technology enables automated and precise measuring of leg geometry within of ≤1° to evaluate lower limb deformities.
Quick results
The time required for the interpretation and diagnosis of lower limb deformities can be reduced from three minutes to < 1 minute (more than three times faster). This leaves more time for patient care.
Implant support
LAMA™ now supports radiographs with total hip and total knee implants, providing 12 standardized measurements for both pre- and post-surgery radiographs.
90%
Up to 90% of the population have leg length discrepancies [6].
200 M
An orthopedic surgeon spends over 8 minutes reading and measuring a single full-leg x-ray [4].
10K €
The reading time with LAMA™ is reduced by up to 90% [4]
Intended use
IB Lab LAMA™ is a radiological fully-automated image processing software device of either computed (CR) or directly digital (DX) images intended to aid medical professionals in the measurement of leg geometry. IB Lab LAMA aids in the detection of knee alignment deformities by measuring relevant angles relevant on standing AP radiographs of the leg. IB Lab LAMA also aids in the detection of leg length discrepancy by providing the following measurements: femur, tibia and full leg length as well as the difference between right and left legs on bilateral images.
It should not be used in-lieu of full patient evaluation or solely relied upon to make or confirm a diagnosis. The system is to be used by trained medical professionals including, but not limited to, orthopedics and
radiologists.
The LAMA Software is intended to be used on humans from 12 years with suspected deformities of the lower extremities among them functional limitations, bio-mechanical and cosmetic indications.
