In situations where we are removing digits such as fingers, hand surgeons perform an operation called ‘ray amputations’. In a finger example, ray amputations are the removal of an entire finger along with the corresponding metacarpal bones in the hand.
Why do rays get amputated?
This technique can be applied to ray amputation of both the middle and ring fingers. In transecting the deep transverse metacarpal ligaments, it is essential to preserve enough for attaching the ligaments to each other so as to minimize gap formation and rotational deformity. Then, the ray is amputated.
What is first ray amputation?
Partial first-ray resections are used to help salvage the foot and maintain bipedal ambulation. Losing the first metatarsophalangeal joint has biomechanical consequences that lead to further foot deformities and result in more proximal amputations of the ipsilateral limb, such as a transmetatarsal amputation.
What is a TMA amputation?
Transmetatarsal amputation, also called TMA, is surgery to remove all or part of your forefoot. The forefoot includes the metatarsal bones, which are the five long bones between your toes and ankle. TMA is usually done when the forefoot is badly injured or infected.
When is Ray amputation done?
The indications for ray resection are ischemic necrosis involving the metacarpal, severe dysfunction of the proximal interphalangeal joint (PIPJ) and amputations at the level of the proximal phalanx (6, 7). Amputations performed distal to the PIPJ have good outcomes without ray resection (6, 8-10).
How much does a ray amputation cost?
The cost of surgery for the amputation of a ring finger can range from $20,000 to $60,000 for a person who may not have insurance. This cost covers the surgeon’s fees, facility fees, hospital stay, anesthetics, and medical supplies.
What are the levels of amputation?
Levels of Amputation
- Shoulder Disarticulation (SD)
- Transhumeral (Above Elbow AE)
- Elbow Disarticulation (ED)
- Transradial (Below Elbow BE)
- Hand/ Wrist Disarticulation.
- Transcarpal (Partial Hand PH)
What is second ray amputation?
Second ray amputation surgical technique With a skin marker, a dorsal longitudinal incision following the shaft of the second metatarsal and then curving around the base of the 2nd toe at the level of the metatarsophalangeal joint (racquet-type incision) was planned (Figure 3A).
Is a ray a metatarsal?
The first ray is a single foot segment consisting of the first metatarsal and first cuneiform bones. Pronation of the subtalar joint lowers the first ray to the ground in early stance5 and dissipates the shock of heel impact.
What does first ray mean?
The first ray is the segment of the foot composed of the first metatarsal and first cuneiform bones. The location of this joint is important as it intersects the transverse and medial longitudinal arches. This segment serves as a critical element in the structural integrity of the foot.
Is Transmetatarsal amputation a major surgery?
Reoperation rates after a TMA range from 8 to 63 percent and approximately one-third of TMAs will result in a major amputation. Despite the risk of complication and low healing rates of a TMA, the procedure remains the standard of care for the aforementioned indications.
What is a transtibial amputation?
Transtibial amputation, or below-knee amputation, is a surgical procedure performed to remove the lower limb below the knee when that limb has been severely damaged or is diseased. Most transtibial amputations (60%–70%) are due to peripheral vascular disease, or disease of the circulation in the lower limb.
What is a Boyd amputation?
The Boyd amputation is a surgical technique used to treat osteomyelitis of the foot. This amputation is a technically more difficult procedure to perform than the Syme amputation, but it offers certain advantages. The Boyd amputation provides a more solid stump because it preserves the function of the plantar heel pad.
Is disarticulation the same as amputation?
Surgical technique: Knee disarticulation is a very atraumatic procedure, compared to transfemoral amputations. Neither bones nor muscles have to be severed, just skin, ligaments, vessels, and nerves. Even the meniscal cartilages may be left in place to act as axial shock absorbers.
What is a quarter section amputation?
surgical oncology. Forequarter amputation is amputation of the arm, scapula and clavicle. It is usually performed as a last resort to remove a cancer, but decreasingly so as limb-sparing operations improve.
How painful is a finger amputation?
How painful is a finger amputation? As fingertips are rich in nerve supply, they are extremely sensitive; hence, finger amputation is extremely painful. The finger may be sensitive to cold and heat for a year or more.
Is amputation covered by insurance?
Amputation surgery generally is covered by health insurance, often even in cases where a patient chooses to undergo the surgery because of pain or a limb that is not useful.
Can fingers be reconstructed?
Conclusions. The full-length finger reconstruction procedure allows for construction of natural-appearing full-length fingers with normal PIP joint positioning and a near-normal functional recovery for proximal digital amputation.
What are the five types of amputation?

What is an amputation list three 3 types of amputations?
Major amputations are commonly below-knee- or above-knee amputations. Common partial foot amputations include the Chopart, Lisfranc, and ray amputations. Common forms of ankle disarticulations include Pyrogoff, Boyd, and Syme amputations.
What type of doctor performs amputations?
General and vascular surgeons now perform the vast majority of amputations, and physiatrists oversee rehabilitation.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
