An above-elbow amputation, formally called a transhumeral amputation, removes the arm through the humerus bone between the shoulder and the elbow. It is less common than a below-elbow amputation but far more functionally disruptive, because the person loses not just the hand and wrist but also the elbow joint, which is critical for positioning the hand in space. That extra lost joint makes virtually everything harder, from eating to getting dressed to using a prosthetic limb, and it shapes nearly every decision that follows the surgery.
Why It Happens
Trauma is the leading cause of upper-limb amputation overall, and that holds true for the above-elbow level as well. Industrial machinery injuries, motor vehicle crashes, military combat, and electrical burns account for the majority of cases, which tend to skew toward younger men. Medical conditions also play a substantial role: cancers of the bone or soft tissue (like osteosarcoma), severe infections that don’t respond to treatment, vascular disease, and complications from diabetes can all leave surgeons with no better option than amputation. A 2025 systematic review of global upper-limb amputation data confirmed that while traumatic causes predominated, medical conditions contributed substantially to upper-limb loss among people living with disabilities.1Europe PMC / Annals of Rehabilitation Medicine. Global Overview of Acquired Upper Limb Amputation Epidemiology: A Systematic Review of Prevalence, Incidence, Level, and Etiology Below-elbow amputations remain the most common major upper-limb level, meaning that when surgeons can save the elbow, they typically do. Above-elbow amputation is usually reserved for situations where tissue damage or disease extends too far up the arm to permit a shorter amputation.
What the Surgery Involves
The primary surgical goal is to create a residual limb that is comfortable, durable, and useful for prosthetic fitting. The humerus is shortened to a length that will serve as a lever arm while still leaving room for a prosthetic elbow mechanism to sit without making the overall arm length look awkward. Surgeons then sculpt the soft tissue around the bone end using techniques called myodesis, where muscle is attached directly to bone, and myoplasty, where opposing muscle groups are sewn together over the bone tip. These techniques reduce tissue redundancy and create a stable, padded envelope over the bone.2Operative Techniques in Orthopaedics. Optimizing Transhumeral Amputations
Preserving as much humeral length as possible matters a great deal. A longer residual limb gives the person more leverage to control a prosthesis and more range of motion at the shoulder. Even a couple of centimeters of extra bone can change the experience. At the same time, the surgeon has to ensure there is enough healthy soft tissue to cover the bone without tension, because a poorly padded stump will make wearing a socket painful or impossible.
Why the Missing Elbow Changes Everything
People often underestimate how much the elbow contributes to daily life. Your elbow lets you bring food to your mouth, reach into a cabinet, button a shirt, hold a phone to your ear. Losing it doesn’t just take away a joint; it takes away the ability to position the hand anywhere in front of or beside the body without compensating with the trunk and shoulder.
Studies using motion-capture technology confirm this. Prosthesis users with above-elbow amputations rely on significantly greater trunk movements during reaching tasks compared to people without amputations, essentially leaning and twisting their torso to substitute for the missing elbow and wrist.3PubMed. Characterization of compensatory trunk movements during prosthetic upper limb reaching tasks Walking is affected too. Because the prosthetic arm doesn’t swing naturally the way a biological arm does, the intact arm tends to swing more to compensate, creating noticeable asymmetry and placing higher-than-normal loads on the trunk.4PubMed Central. Transhumeral prosthesis use affects upper body kinematics and kinetics These compensatory patterns aren’t just awkward; over time, they set the stage for pain and injury elsewhere in the body.
Functional outcome scores reflect the difficulty. When researchers test upper-limb amputees on everyday tasks, people with more proximal amputations consistently score lower than those with below-elbow amputations.5Archives of Physical Medicine and Rehabilitation. Development and Initial Psychometric Evaluation of the Activities Measure for Upper Limb Amputees6PubMed. Brief activity performance measure for upper limb amputees: BAM-ULA The gap isn’t subtle. Losing the elbow essentially doubles the number of joints a prosthesis has to replace, and every added joint introduces complexity, weight, and potential points of frustration.
Overuse Injuries and Secondary Pain
Your body is adaptive, and when an arm is missing it will recruit the shoulder, spine, and opposite limb to fill in. The cost shows up as overuse injuries. In a study of service members with combat-related upper-limb amputations, roughly 60 to 65 percent developed at least one musculoskeletal overuse condition within the first year. They were three to nearly five times more likely to develop problems in the remaining upper limb, neck, upper back, lower limbs, and low back compared to people who had sustained only minor combat injuries.7PubMed. Development of overuse musculoskeletal conditions after combat-related upper limb amputation: a retrospective cohort study Shoulder impingement in the sound arm, cervical spine pain from tilting the trunk to reach, and repetitive strain from using one hand for tasks normally shared between two are all common. These aren’t afterthoughts; for many people, the secondary pain eventually becomes a bigger daily concern than the amputation itself.
Prosthetic Options
There are two broad categories of upper-limb prostheses that do functional work: body-powered and myoelectric. Body-powered devices use a cable and harness system. You shrug or flex the opposite shoulder, the cable pulls, and the prosthetic elbow or hand opens or closes. They’re rugged, relatively lightweight, give direct tactile feedback through cable tension, and require less maintenance. Myoelectric devices use sensors on the skin that detect tiny electrical signals from muscles in the residual limb, then translate those signals into motorized joint movements. They look more lifelike, can generate stronger grip, and some people find them more comfortable for lighter tasks.
A systematic review comparing the two found that neither type offers a clear general advantage. Body-powered prostheses outperform on durability, training time, and feedback. Myoelectric prostheses score better on appearance and are associated with less phantom-limb pain, possibly because using the residual muscles keeps the brain’s body map more engaged.8PubMed. Differences in myoelectric and body-powered upper-limb prostheses: Systematic literature review Many above-elbow amputees end up owning both types and switching based on the task at hand.
Prosthetic rejection, meaning the person stops wearing the device, is a real and persistent problem, especially at the transhumeral level. Proximal amputations are more likely to lead to rejection than distal ones.9PubMed. Prosthesis rejection in acquired major upper-limb amputees: a population-based survey The reasons break down into two stages. Some people never start wearing a prosthesis because they don’t perceive enough benefit relative to the hassle. Others try one and abandon it because the comfort, weight, or control isn’t satisfactory. In surveys, roughly 60 percent of dissatisfied users cite socket discomfort and over half cite device weight as major complaints.10PubMed. Current rates of prosthetic usage in upper-limb amputees – have innovations had an impact on device acceptance? For an above-elbow prosthesis, the socket wraps high around the shoulder and sometimes across the chest, which can feel restrictive and hot. Adding a motorized elbow to a motorized hand creates a heavier device. It’s not hard to see why some people decide they’d rather just use their remaining hand.
Bone-Anchored Prostheses
One way to deal with socket discomfort is to skip the socket entirely. Bone-anchored, or osseointegrated, prostheses use a metal implant fused directly to the humerus, with a small post extending through the skin to which the prosthesis clips on. Think of it as a permanent mounting point built into the bone.
The appeal is substantial: no socket pressing on soft tissue, no harness, improved range of motion at the shoulder, and a more direct mechanical connection that gives the user better awareness of where the prosthesis is in space. In a small series of four transhumeral amputees, implant survival was 100 percent at a median of eleven months. Prosthetic use went from zero hours per week to an average of fourteen, and all four participants improved their ability to perform daily activities with the device.11PubMed. Surgical technique of a bone-anchored prosthesis for transhumeral amputees The technology is still in relatively early stages for the upper limb and carries its own risks, particularly infection at the skin-implant junction, but for people who cannot tolerate a socket it may be the difference between wearing a prosthesis and not.
Targeted Muscle Reinnervation
One of the most significant surgical advances for above-elbow amputees in the past two decades is targeted muscle reinnervation, or TMR. The basic idea is to take the nerves that once controlled the hand, wrist, and elbow and reroute them into nearby chest or upper-arm muscles that have lost their original function. Once those nerves grow into the new muscle targets, the muscles respond to the person’s intention to move phantom fingers or a phantom elbow. Surface sensors can pick up these signals and translate them into prosthetic commands.
TMR was originally developed to improve myoelectric prosthesis control, and it has been shown to do exactly that, especially for high-level amputations where few residual muscles remain.12PubMed Central. Targeted Muscle Reinnervation for the Upper and Lower Extremity In a randomized clinical trial comparing pattern recognition control (which works hand-in-hand with TMR) to conventional direct control, subjects using pattern recognition performed significantly better on a standardized hand-assessment battery and completed a manual dexterity task roughly a third faster.13Scientific Reports. Myoelectric Pattern Recognition Outperforms Direct Control for Transhumeral Amputees with Targeted Muscle Reinnervation: A Randomized Clinical Trial
But TMR has turned out to be more than a prosthetic control strategy. It is also emerging as a leading surgical technique for preventing and treating phantom limb pain and neuroma pain. The severed nerve endings that form after any amputation can develop into painful knots called neuromas. By rerouting those nerves into functional muscle targets, TMR gives the nerve somewhere to go, reducing the likelihood that a neuroma forms in the first place.14PubMed Central. Targeted muscle reinnervation for the management of pain in the setting of major limb amputation When TMR is performed at the time of amputation, results are encouraging: in one study, 62 percent of patients who received TMR during the initial surgery were free of phantom limb pain, compared with 24 percent of controls. Pain medication use also dropped; at roughly eight months of follow-up, under half of TMR patients remained on pain medications versus 84 percent of controls.15PubMed Central. Treatment of Phantom and Residual Limb Pain in Amputees With Targeted Muscle Reinnervation16PubMed. Targeted Muscle Reinnervation at the Time of Upper-Extremity Amputation for the Treatment of Pain Severity and Symptoms Because of this dual benefit, many surgeons now consider TMR a standard part of above-elbow amputation rather than an optional add-on.
Regenerative Peripheral Nerve Interfaces
A newer approach called the regenerative peripheral nerve interface, or RPNI, pushes the neural-prosthetic boundary further. Where TMR reroutes nerves into existing muscles, RPNIs wrap a small piece of free muscle graft around each severed nerve end. The nerve reinnervates the graft, creating a tiny, independent muscle signal source for each nerve. The result is more individual control channels than TMR alone provides, which becomes valuable when you need to decode distinct finger and wrist movements from a residual limb that has no fingers or wrist.
In human trials, RPNIs have proved biologically stable and capable of amplifying motor signals with high signal-to-noise ratios. One participant maintained real-time prosthetic hand control above 94 percent accuracy for over 600 days without needing the control algorithm recalibrated, and completed a multi-step coffee-making task with 99 percent accuracy for a similar duration.17Journal of Neural Engineering. Long-term upper-extremity prosthetic control using regenerative peripheral nerve interfaces and implanted EMG electrodes Earlier work demonstrated that subjects could control a prosthetic hand in real time for up to 300 days without recalibration.18PubMed Central. A regenerative peripheral nerve interface allows real-time control of an artificial hand in upper limb amputees
RPNIs also open the door to sensory restoration. When researchers electrically stimulated median and ulnar nerve RPNIs in two participants, the subjects reported feeling phantom finger movements and skin sensations in anatomically appropriate locations: tingling at the base of the thumb when the median nerve RPNI was stimulated, flexion at the ring finger when the ulnar nerve RPNI was activated.19PubMed Central. Restoration of proprioceptive and cutaneous sensation using Regenerative Peripheral Nerve Interfaces (RPNIs) in humans with upper-limb amputations Separately, implanted nerve cuff electrodes have been used to deliver graded sensory feedback proportional to grip force, allowing prosthesis users to feel how hard they’re squeezing an object.20PubMed Central. Sensory feedback by peripheral nerve stimulation improves task performance in individuals with upper limb loss using a myoelectric prosthesis This kind of bidirectional communication, where the prosthesis both receives motor commands and sends sensory information back to the brain, is considered the next major frontier in prosthetics.
Fully Implanted Sensors and Wireless Systems
Surface electrodes have always had limitations: sweat degrades the signal, the socket can shift, and above-elbow amputees simply don’t have many accessible muscle sites on the skin. Fully implanted myoelectric sensors sidestep these problems by recording directly from inside the muscle and transmitting wirelessly to the prosthesis. In the first human trial of one such system, a below-elbow amputee was able to independently and simultaneously control three degrees of freedom in a prosthetic wrist and hand on the first day of training, something he reported feeling more natural and intuitive than his previous prostheses.21PubMed Central. First-in-Man Demonstration of Fully Implanted Myoelectric Sensors for Control of an Advanced Electromechanical Arm by Transradial Amputees
More recently, a wireless multi-electrode system has been tested with above-elbow amputees specifically in mind. Because above-elbow amputees face the biggest mismatch between available control signals and the number of joints they need to operate, having many independent recording channels becomes especially important. In cadaver and animal tests, the system provided high-bandwidth interfacing through numerous intramuscular electrode sites, which researchers believe could be combined with TMR to give above-elbow users access to more degrees of freedom than current surface-electrode approaches allow.22PubMed Central. Feasibility of a Wireless Implantable Multi-electrode System for High-bandwidth Prosthetic Interfacing: Animal and Cadaver Study
Psychological and Social Impact
Losing an arm above the elbow affects far more than physical function. The arm is visible, constantly noticed by others, and central to social interactions like handshakes. Research consistently finds that upper-limb amputees experience greater body image disturbance and poorer psychosocial adjustment than lower-limb amputees.23PubMed. Comparison of upper limb amputees and lower limb amputees: a psychosocial perspective In a large survey of upper-extremity amputees, over half screened positive for depression, PTSD, or both. About a third met criteria for depression alone, and an additional one in five had co-occurring depression and PTSD. Women and ethnic minority participants were at higher risk, as were those with greater activity restriction and pain interference.24PubMed. Psychological distress among persons with upper extremity limb loss
Among adolescents, body image disturbance predicted both psychosocial adjustment and quality of life, and those experiencing phantom limb pain reported lower quality-of-life scores. Getting a prosthesis fitted earlier in life correlated with less body image disturbance later.25PubMed. Body image disturbance, psychosocial adjustment and quality of life in adolescents with amputation These findings suggest that rehabilitation programs should treat psychological care as a core component rather than an afterthought, and that early prosthetic fitting in younger patients may carry benefits beyond physical function.
Children and Growing Bones
Transhumeral amputation in children introduces a problem that adults don’t face: terminal bone overgrowth. In growing children, the cut end of the humerus can keep producing new bone that pushes against the skin and soft tissue at the tip of the residual limb, sometimes requiring repeated revision surgeries. A modified amputation technique that shortens the bone acutely while preserving the distal growth plate has been reported to prevent overgrowth, avoid repeated surgeries, and maintain enough length and width at the stump to allow comfortable prosthetic fitting as the child grows.26JBJS Case Connector. Modified Transhumeral Amputation: A Case Report These details matter because a child who undergoes an above-elbow amputation at age seven will need decades of prosthetic use, and the shape and health of the residual limb at that first surgery sets the trajectory for everything that follows.
Cost and Insurance Barriers
High-tech prosthetic limbs don’t come cheap. A myoelectric arm with a powered elbow and hand can run from tens of thousands to well over a hundred thousand dollars, and that’s before you account for replacement parts, socket refitting (which is needed regularly as the residual limb changes shape), and the rehabilitation hours required to learn to use the device. Body-powered prostheses cost less but still run into thousands of dollars, and no prosthesis lasts forever.
In the United States, insurance coverage varies enormously. Research from the Veterans Affairs healthcare system, which doesn’t impose co-pays or caps, found that the prosthetic prescription and repair rates in that system would likely exceed typical annual and lifetime caps set by most private insurance plans. In states without prosthetic parity laws, those costs almost certainly limit access to the devices people need.27PubMed. Prescription and repair rates of prosthetic limbs in the VA healthcare system: implications for national prosthetic parity For above-elbow amputees, who need more complex and expensive prostheses than below-elbow users, the gap between what’s available and what’s affordable can be especially wide.
Virtual Reality for Prosthesis Training
Learning to operate a powered above-elbow prosthesis is a cognitively demanding task. You have to learn which muscle contractions map to which prosthetic movements, sequence through multiple joints, and calibrate your grip force without being able to feel what you’re holding. Traditional training happens in a clinic with a therapist, but virtual reality is beginning to supplement or even replace parts of that process. In a recent study, both therapists and prosthesis users rated a virtual reality training environment highly for usability and motivation, with acceptable cognitive workload. Both groups expressed interest in integrating VR into routine rehabilitation.28PubMed. Therapists’ and prosthesis users’ assessments of a virtual reality environment designed for upper limb prosthesis control training VR has the advantage of being available for practice at home, which matters for a skill that improves with repetition and degrades without it.
