Summary
Osseointegration (OI) prostheses show high satisfaction and minimal mobility limitations for lower-limb amputees. Transtibial amputees experienced fewer limitations, suggesting benefits for below-knee amputations.
Area of Science:
- Orthopedics
- Biomedical Engineering
- Rehabilitation Medicine
Background:
- Socket-based prostheses can cause periprosthetic pain and poor fit, impacting amputee quality of life.
- Osseointegration (OI) offers an alternative by implanting a titanium rod into the residual limb.
- Concurrent nerve and soft-tissue reconstruction can enhance comfort and reduce pain.
Purpose of the Study:
- To evaluate patient satisfaction with osseointegration (OI) prostheses.
- To assess mobility limitations in lower-limb amputees using OI prostheses.
- To compare outcomes between transtibial and transfemoral amputees with OI.
Main Methods:
- A cross-sectional survey was conducted with lower-limb amputees who received OI implants.
- Demographics (age, amputation level, BMI) were collected.
- The Trinity Amputation and Prosthesis Experience Scales (TAPES) assessed satisfaction and activity limitations postoperatively.
Main Results:
- Twenty-seven patients (12 transtibial, 15 transfemoral) participated.
- Mean satisfaction with OI prostheses was 7.56/10.
- Transtibial amputees reported significantly lower mobility limitations (9.1) than transfemoral amputees (13.8).
Conclusions:
- Osseointegration (OI) prostheses yield high satisfaction and minimal activity limitations.
- OI prostheses offer ambulation benefits, particularly for transtibial amputees.
- Future research should compare OI with traditional socket-based prostheses using the TAPES survey.

Measuring blood pressure is a fundamental skill in healthcare that aids in diagnosing and monitoring hypertension and other cardiovascular conditions. An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the...

Relating Reaction Mechanisms
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...

The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...
