LAMA™

Automated Assessment of Long Leg Radiographs


Problems

Currently, pre-and post-total knee arthroplasty (TKA) lower limb alignment is assessed manually or with the aid of interactive software applications, resulting in high intra- and inter-reader variability, poor reproducibility and calibration errors.

Solutions

Fully-automated measurements aid users in quantifying limb-length discrepancy and quantitative knee alignment parameters on uni- and bilateral AP full leg radiographs.

LAMA™ is here to support you!

Accurate & Precise

Deep learning technology enables automated accurate and precise measurement of knee alignment within ≤1° and leg-length discrepancy within ≤ 2mm [1]

Fast

Reading and reporting time of lower limb deformities radiographs can be reduced from 3 minutes to <1 minute (more than 3x faster) resulting in more time for patient care [2]

Implant Support

IB Lab LAMA™ now supports radiographs with total hip and total knee implants, providing 13 standardized measurements for both pre- and post-surgery radiographs [3]

Product description

LAMA™ uses deep learning technology to provide precise fully-automated geometric length and angle measurements of the lower limb on full leg X-ray images. The outputs aid healthcare professionals who are interested in the analysis of leg-length discrepancy and knee alignment in adult patients with suspected or present deformities of the lower extremities. 

The user does not interact directly with IB Lab LAMA™ except to accept or reject the generated report findings via cleared third party medical viewers. The measurements are compared to fixed predetermined norm-ranges, based on standard state of the art clinical practices hard-coded into the software. Outputs are summarised in reports that can be viewed on any cleared medical DICOM viewer.


Findings

IB Lab LAMA™ provides the following measurements:

mechanical axis deviation

● full leg length

● femur length

● tibia length

● leg length discrepancy

● hip knee ankle angle

● anatomical tibiofemoral angle

● anatomical mechanical angle

● joint-line convergence angle

● mechanical lateral proximal femoral angle

● mechanical lateral distal femoral angle

● mechanical medial proximal tibia angle

● mechanical lateral distal tibia angle


Intended use

IB Lab LAMA™ is a fully-automated radiological image processing software device intended to aid users in the measurement of limb-length discrepancy and quantitative knee alignment parameters on uni- and bilateral AP full leg radiographs of individuals at least 22 years of age. It should not be used in-lieu of full patient evaluation or solely relied upon to make or confirm a diagnosis. The software device is intended to be used by healthcare professionals trained in radiology. IB Lab LAMA™ is not indicated for use on radiographs on which Ankle Arthroplasties and/or Unicompartmental Knee Arthroplasties are present.
