Study Notes
Lower-Extremity Amputations and Diabetes Mellitus
- 20.8 million Americans have diabetes mellitus (7% of the population), with 6.2 million undiagnosed.
- In 2002, 224,092 deaths were linked to diabetes, and the associated costs totalled $132 billion.
- Approximately 82,000 lower-extremity amputations were related to diabetes in 2002.
- Diabetes patients account for over 60% of all lower-extremity amputations.
- Diabetic individuals have a 10-fold higher risk of amputation compared to non-diabetics.
- Men with diabetes are 1.4-2.7 times more likely to have an amputation than women with diabetes.
- The risk of amputation is higher for certain ethnic groups (Mexican Americans, African Americans, and Native Americans compared to whites). Morbid obesity is also correlated to diabetic foot complications.
Amputation Treatment and Prognosis
- Amputation used to be viewed as a failure and source of disability and disfigurement.
- Modern approaches focus on comprehensive rehabilitation after amputation.
- The goal of amputation surgery it to preserve as much functional limb as possible, as residual limb length has significant impact on energy expenditure during ambulation.
- Patient education and proper management of diabetes are crucial in preventing amputations.
- 30% of amputees lose their contralateral limb within three years, and two-thirds die within five years after a major leg amputation. Only 50% of major amputees use prostheses.
Amputation Levels and Decision Making
- Toe amputations are common (24% of all diabetic amputations). Surgical incisions can be side-to-side or plantar-to-dorsal for better soft tissue use.
- Ray amputations involve toe amputations and metatarsals, with the goal of preserving forefoot stability.
- Transmetatarsal amputations (TMAs) are frequently performed, showing higher success rates when compared to transtibial amputations.
- Syme amputations (ankle disarticulation) provide a relatively useful residual limb that permits greater energy expenditure and function for patients who are candidates.
- Transtibial amputations are the most common type.
- Pre-operative assessment is vital, including tissue quality, infection, vascularity, and patient's overall health.
- An ankle-brachial index of 0.5 and a transcutaneous partial pressure of oxygen (TcP02) between 20 and 30 mmHg are accepted parameters indicating suitable healing.
Post-Surgical Care and Complications
- Proper postoperative care includes addressing wound healing, proper prosthetic fitting and rehabilitation.
- Factors like infection rates and the need for multiple surgeries are often associated with complication and failure rates.
- Ensuring the patient's overall health; adequate nutrition is important, especially for diabetic patients, in helping wound healing.
- Patient satisfaction is impacted by residual limb comfort, contralateral limb status, prosthetic function, and exercise capabilities.
