Used routinely in maxillofacial reconstructive surgery, the chondrocostal graft is also applied to hand surgery in traumatic or pathologic indications. The purpose of this overview was to analyze at long-term follow-up the radiological and histological evolution of this autograft, in hand and wrist surgery. We extrapolated this autograft technique to the elbow by using perichondrium. Since 1992, 148 patients have undergone chondrocostal autograft: 116 osteoarthritis of the thumb carpometacarpal joint, 18 radioscaphoid arthritis, 6 articular malunions of the distal radius, 4 kienbock's disease, and 4 traumatic loss of cartilage of the proximal interphalangeal (PIP) joint. Perichondrium autografts were used in 3 patients with elbow osteoarthritis. Magnetic Resonance Imaging (MRI) was performed in 19 patients with a mean follow-up of 68 months (4–159). Histological studies were performed on: Whatever the indication, the reconstruction by a chondrocostal/ostochondrocostal or perichondrium graft yielded satisfactory clinical results at long-term follow-up. The main question was the viability of the graft.
Despite the strong mechanical strain in the hand and wrist, chondrocostal graft is a biological arthroplasty that is trustworthy and secure over the long term, although it can cause infrequent complications inherent to this type of surgery. Despite the inevitable histological modification, the cartilage remains alive and is of satisfactory quality at long term follow-up and fulfills the requirements for interposition and reconstruction of an articular surface. The perichondrium graft constitutes a new arsenal to cure cartilage resurfacing. The importance of perichondrium for the survival of the grafted cartilage, as previously reported, as well as its role in resurfacing, is being investigated.
Intra-operative fluoroscopy in thumb metacarpophalangeal joint arthrodesis has been recommended as a means of achieving optimal alignment more consistently. This is not our current practice. A patient attending dissatisfied with an arthrodesis in excessive flexion performed outwith our unit highlighted the potential for problems, and we therefore elected to review our own outcomes. An evaluation of the alignment achieved in thumb metacarpophalangeal joint arthrodeses, to determine if current outcomes satisfactory or if fluoroscopic assistance should be considered. Radiological review of alignment of thumb metacarpophalangeal joint arthodeses carried out by two Consultant Surgeons with specialist interests in
