Background In 1964, faced with the challenge of traumatic amputation, a team of surgeons at Clinica Guayaquil was convinced that the transplantation of a hand could significantly improve function and quality of life for the recipient. With a current but basic understanding of immunosuppression, the surgeons identified a recipient and waited for the correct donor. A human hand transplant had never been performed to date. Methods The surgeons' criteria for the recipient included a young healthy individual who had sustained a traumatic amputation at the distal forearm level with full motion of the proximal joints. Communication with receiving hospitals and military facilities identified what they perceived to be a feasible donor for an allograft transplantation. Consent was obtained from the family in conjunction with the local military medical authorities and the clergy. Iced saline solution and Heparin irrigation were to be used to prepare the donor extremity. The immunosuppression regimen, limited at the time, consisted only of intravenous cortisone, Imuran, and a single dose of radiation. Results A member of the Ecuadorian marine sustained a limited blast injury that amputated his dominant hand but spared the forearm. He was transferred to the emergency department of Clinica Guayaquil. A donor who had recently died in a nearby hospital was identified not long after. A successful technical surgical transplantation was achieved. Consultants from major hospitals around the world (including Peter Bent Brigham Hospital) convened at the patient's bedside to observe the results. Despite all efforts, the patient suffered an irreversible rejection at 21 days post-transplant. Conclusion This was the first allograft transplantation of a hand. The surgeons embarked on an intervention never tried before, firmly believing that better function and quality of life would result. The bravery of this surgical team was commendable. This early surgical endeavor opened the way for future successes in transplant surgery today.

Toe Transfer

The distinctive prehensile functions of the human hand are orchestrated by the thumb. Without a thumb, the hand lacks critical movements allowing for pinch, grasp, and fine manipulation. Based on the patient’s individual needs, occupation, and desires, thumb reconstruction should be offered to every patient with a traumatic amputation. Position, stability, mobility, and sensation command attention when reconstructing the absent thumb. We present the spectrum of various techniques available for reconstructing a useful thumb.

Recent studies of the anthropometry and selected biomechanical characteristics of hands are summarized. These include: (1) conventional anthropometry of male and female hands, (2) the anthropometry of the relaxed hand, (3) comparison of certain engineering anthropometric and performance parameters between bare and pressure-gloved hands, and (4) the ability to retain grips on selected handles under high dynamic loads. The utility of these data for human factors engineering is discussed.

Case description: Conventional methods for producing custom prosthetic fingers are time-consuming, can be uncomfortable for the patient, and require a skilled prosthetist. The subject was a 40-year-old male with congenital absence of the thumb and related metacarpal bone on the right non-dominant hand, anomaly of the lengths of individual upper limb segments, and contracture of the elbow joint. This hand presentation made it impossible for him to perform thumb opposition, which is a very important function for common daily activities. Objective: The goal was to design an individual passive thumb prosthesis using free open-source software, 3D scanning technology, and additive manufacturing methods (i.e., fused filament fabrication). Study design: Case report. Treatment: Artificial thumb prostheses with two types of bases and fastening interfaces were designed and manufactured. One combination was chosen as the best alternative. Outcomes: The shape, positioning, firmness, and fastening of the prosthesis were compliant enough for the patient to be able to hold objects with his healthy fingers and artificial thumb. This innovative approach to fabrication of a custom thumb prosthesis provided considerable advantages in terms of custom sizing, manufacturing time, rapid production, iteration, comfort, and costs when compared to conventional methods of manufacturing a hand prosthesis. Conclusion: The methodology of designing and manufacturing a prosthetic thumb using 3D scanning and additive manufacturing technologies have been demonstrated to be adequate from a practical point of view. These technologies show potential for use in the practice of prosthetics.

Cross Match

The first Belgian hand transplant was a 22 year-old man with a traumatic amputation of his dominant hand at the junction of the middle and distal thirds of the forearm. The donor and recipient had three HLA mismatches. The cross-match was negative. The total ischaemic time was slightly over 6 hours. Immunosuppression included antithymocyte globulins at induction and tacrolimus, mycophenolate mofetil and prednisolone as induction and maintenance therapy. There has been no episode of rejection. The only significant complications, except for transient hyperglycaemia, were psychological. At 37 months post-transplantation, the patient has fully incorporated his transplant into his self-image and is back at work. He has good sensibility (two-point discrimination of 6 mm at the thumb and index finger pulps), acceptable wrist and finger motion with functioning intrinsic muscles. According to Chen’s criteria, the result is good to excellent.

It is a known fact that a disabled person is a greater burden to society than a dead person. Krukenberg operation, first described by German army surgeon in 1917, Hermann Krukenberg, converts a forearm stump into a pincer, so as to retain some dexterity of the hand rather than it being reduced to a mere stump. We report this case of Krukenberg operation performed in a tertiary care setup, wherein an amputated forearm stump was converted into a functional pincer that can result in huge advantage for poor amputee patients in developing countries who rely heavily on the functionality of their hands to earn their everyday meal and are unable to bear the expense of costly prosthesis. One such patient, a 25-year-old male hailing from a very poor background who came to us with traumatic amputation of his dominant hand.

The Individual

The human hand is a versatile organ that performs a variety of activities in daily life. The coordination of digits allows them to deal with objects of various sizes and shapes with an appropriate range of motions (ROM). A systematic literature review was performed to identify the clinical and non-clinical factors which affected the normal ROM, grip strength (GS), and dexterity of hand. The overall outcomes of the systematic review showed that: the performance of the individual declined as the age progressed; the performance of the dominant hand (DH) of an individual was better compared to his/her non-dominant hand (NDH); the tasks performed by a healthy hand was more efficient compared to a diseased one; appropriate rehabilitation programs/exercise techniques after a disease or injury improved the ROM, GS, and dexterity of hand post-surgery on par to a healthy hand.

Abstract Unique anatomical features of the human hand facilitate our ability to proficiently and forcefully perform precision grips and in-hand manipulation of objects. Extensive research has been conducted into the role of digits one to three during these manual behaviours, and the origin of the highly derived first digit anatomy that facilitates these capabilities. Stone tool production has long been thought a key influence in this regard. Despite previous research stressing the unique derived morphology of the human fifth digit little work has investigated why humans alone display these features. Here we examine the recruitment frequency, loading magnitude, and loading distribution of all digits on the non-dominant hand of skilled flintknappers during four technologically distinct types of Lower Palaeolithic stone tool production. Our data reveal the fifth digit to be heavily and frequently recruited during all studied behaviours. It occasionally incurred pressures, and was used in frequencies, greater or equal to those of the thumb, and frequently the same or greater than those of the index finger. The fifth digit therefore appears key to >2 million years of stone tool production activities, a behaviour that likely contributed to the derived anatomy observed in the modern human fifth ray.
