Surgical Technique in Cadaveric Donors for Partial Hand Allotransplant in Patients With Rheumatoid Arthritis

Partial Hand Transplant: Lessons Learned From Cadaveric Dissection Studies

As the field of vascularized composite allotransplantation continues to expand, new upper extremity transplant candidates are being considered. We recently evaluated a bilateral amputee who had a mid-forearm amputation and a contralateral metacarpal hand amputation. In the latter limb, a "partial" hand transplant that preserved the majority of the patient's existing hand, including a partially severed thumb with intact thenar muscle function, was proposed. The feasibility of this partial hand transplant was studied in fresh-frozen cadaver limbs. This report details the proposed approach, the cadaveric dissections, and the lessons learned from these dissections. Issues of osteosynthesis, microvascular planning, and intrinsic muscle recovery are discussed, all of which are critical considerations for partial hand transplant candidates. Ultimately, the partial hand approach was felt to be inferior to a more conventional distal forearm transplant in this particular candidate. Practical, functional, and ethical implications of such decision are presented.

The future of rheumatoid arthritis and hand surgery - combining evolutionary pharmacology and surgical technique

Rheumatoid arthritis is a systemic autoimmune disease of uncertain aetiology, which is characterized primarily by synovial inflammation with secondary skeletal destructions.Rheumatoid Arthritis is diagnosed by the presence of four of the seven diagnostic criteria, defined by The American College of Rheumatology.Approximately half a million adults in the United Kingdom suffer from rheumatoid arthritis with an age prevalence between the second and fourth decades of life; annually approximately 20,000 new cases are diagnosed.The management of Rheumatoid Arthritis is complex; in the initial phase of the disease it primarily depends on pharmacological management. With disease progression, surgical input to correct deformity comes to play an increasingly important role. The treatment of this condition is also intimately coupled with input from both the occupational therapists and physiotherapy.
