We support the concept of avoiding straight incisions, and particularly straight axial incisions, in the management of Dupuytren's contracture.1
Likewise we applaud using skin hooks instead of toothed forceps, which practice we have found reduces pain, scarring and postoperative infection significantly.
However the multiple Zplasties suggested by Mennen produces a problem in that there is shortening of the transverse axis of the palm. At times this results in difficulty flattening the palm.
Therefore, over the last 40 years the technique of 'detour incisions' has been used, whereby the incisions follow only the skin creases in the hand. The incidence of recurrence has been comparable to that reported by Mennen. Further, it has not been our practice for some years to splint the hand post-operatively (Figures 1 and 2).
It is also our policy to restrict diathermy2 to the minimum and then to use not more than 8 watts power.
We have found that copious washing of the wounds throughout the procedure reduces both infection3 and (inflammatory) pain.

Dear Editorial Board of the SA Orthopaedic Journal
Please find enclosed the manuscript 'Letter to editor: Evaluation of periarticular aggressive benign bone tumours treated with cementation and a locked plate' by Sanjay Meena to be submitted as a letter to editor in the SA Orthopaedic Journal.
I believe that our observation could be of interest to readers of this journal.

I read with interest the article 'Evaluation of periarticular aggressive benign bone tumours treated with cementation and a locked plate'.1 I must congratulate the authors for the research which is highly relevant in developing country like ours. The availability of indigenous affordable prosthesis may enthuse many a young surgeon to advocate excision and replacement in large or recurrent GCTs. A megaprosthesis is an excellent option in well-selected cases but this enthusiasm must be tempered by the fact that, because GCT is a benign lesion, the patient is likely to have a normal lifespan and a biological reconstruction may in the long term prove to be a more durable option, especially keeping in mind the socio-economic strata to which most of our patients belong. The authors may have used the sandwich technique in their patients to maintain the smoothness of articular cartilage and prevent early osteoarthritis. In this technique, allograft/autograft is packed adjacent to the subarticular surface. A layer of gelfoam is layered over this and the remaining cavity is packed with cement.2 This helps reduce heat damage from the curing cement, and the subarticular bone graft after consolidation should theoretically prevent articular degeneration.3 Another perceived advantage is that, should recurrence occur, the danger of damage to articular cartilage during removal of cement is reduced.
Liquid nitrogen was used as a further adjunct whenever feasible in this study. Cryosurgery using liquid nitrogen first propagated by Marcove, is associated with a high incidence of local wound and bone complications.4 I once again congratulate the author for this excellent study.
