Ottobock 4R52 Bionic and Prosthetic Component Lower Extremity Prosthesis Analysis Report
Device Identification and General Product Description
The product in the images is a lower extremity prosthesis system designed to restore mobility following lower extremity amputations. The system consists of a socket, a modular tube adapter, adjustment mechanisms, and a foot component.
Brand and Model Information
Examination of the technical label on the metal tube adapter and the connection element clearly shows the brand name as ottobock and the model code as 4R52. The model code 28R is located on the base of the foot component.
Authenticity Assessment
The laser-engraved typography on the metal connection parts, brand logos, standard symbols, and directional arrows regarding torque values indicate that the components comply with the original manufacturer’s standards.
Usage Areas and Compatibility
This product is suitable for orthopedics, traumatology, and physical therapy branches for individuals who have experienced lower extremity loss to perform daily living activities, regain the ability to walk, and increase physical independence.
Quantity Information
The images show one integrated lower extremity prosthesis system and its associated components.
General Status and Condition
The device is in used condition. Slight signs of use, dust accumulation, and superficial abrasions have been observed on the outer surface of the socket and the metal tube parts.
Physical Deformation
There are regional color changes and slight dirt on the skin-colored coating of the socket and its blue inner surface. There are no deep dents or structural cracks on the metal parts.
Mechanical Components
The connection bolts, adjustment clamps, and modular tube mechanism are in place. There is no broken part visible in the images that would hinder the movement capability of the mechanical parts.
Electronic Components
Since the product consists entirely of mechanical and modular components, there are no electronic circuits, screens, or power supplies present.
Accessory Status
The system is equipped with a socket, an adjustable metal tube adapter, a black protective sock, and a foot prosthesis component. There are no extra boxes, spare parts, or external cables.
Battery Status
The device does not have an internal or external battery system.
Label and Inscription Inventory
The metal connection adapter features the ottobock brand, 4R52 model, 15Nm torque indication, max. 100 kg / 220 lbs weight limit, and the CE conformity mark. The 28R, FI, and CE symbol are readable on the sole of the foot. The black adjustment knob on the socket bears the CE logo. These data indicate the maximum load limit the product can carry and the compatible tightening torque values.
Screen Analysis
There is no electronic screen on the device.
Dimensions and Compatibility
The 28R marking on the sole of the foot refers to the measurement and size value of the foot component. The 100 kg / 220 lbs value stated on the weight limit label indicates the maximum user weight that the device can safely support.
Production Year
There is no direct production year indication on the labels or metal surfaces in the images. The design and typographic label characters indicate that the device is a standard model produced in recent years.
Documents
There are no invoices, warranty certificates, user manuals, or similar printed documents in the images.
Usage Duration
There is no counter or data on the device showing the total operating hours or past usage duration.
Existing Faults
There is no evidence of an active fault such as a rupture in the support tube, missing main connection bolts, or mechanical breakage in the images.
Potential Fault Risk
Except for slight abrasions on the socket surface and dust residues around the metal connection clamp, there is no critical risk observed; the general mechanical condition is good.
