Objective: To observe the survival of hand allograft under the state of immunosuppression and the pathological changes of rejection in the recovery process.
Methods: The biopsies of the skin, nerve, muscle, tendon and bone tissue of hand allografts during different stages from 1 day to 7 months after operation were observed using routine histological technique.
Results: No significant changes due to rejection in skin, nerve, muscle and bone tissue were observed. But different degrees of weak rejective changes were found on the wall of blood vessels; in the muscle and nerve the reactions were markedly stronger than those found in skin tissues.
Conclusions: The rejection in deep tissues should be monitored in controlling the rejection of hand allograft.

Although mixing and matching components is a common, safe, and well-documented practice in hip revision surgery, our extensive search indicates that it has not been previously reported for shoulder arthroplasty. This case report presents the use of mixed implants in shoulder revision surgery to reduce morbidity and address flaws in the initial implant design. We describe a case of a patient with multiple epiphyseal dysplasia who was treated for osteoarthritis in his left shoulder with an anatomic shoulder replacement in 2014.

Managing rerupture of the triceps brachii tendon after surgical repair is challenging due to poor tissue quality, retraction, and adhesions. This clinical scenario often requires augmentation with native tissue or tendon allografts. Traditional techniques include V-Y advancement, reinforced triceps advancement with double row or suture bridge fixation, and allograft tendon augmentation.

The restoration of nerve function after the injury might be complicated by the development of a disorganized fibrous mass-a neuroma. This results in sensory and/or motor deficits and pain that can be severely debilitating. Surgical excision of the painful neuroma may leave a gap, which can be bridged using autografts or allografts.

One of the primary challenges in hand microsurgical reconstruction lies in addressing severe hand injuries, particularly those involving multiple finger amputations, as autologous replantation might not fully restore hand functionality. In such scenarios, fully shaped reconstruction of a severed finger combined with Ectopic banking could yield superior reconstructive outcomes and enhance the amputated limb's function. This case report presents a unique approach that combines ectopic replantation of an amputated finger with interphalangeal reconstruction methods to restore both the form and function of the hand.

Purpose: In the adult literature, allograft reconstruction of gapped peripheral nerve injuries has gained popularity over autologous nerve grafting. Allografts have demonstrated similar recovery while eliminating donor site morbidity. There is no well-defined incidence or treatment of such injuries in children.
