case_images: An ulcer developed on the posterior-distal aspect of his residuum (Figure 2a) and it worsened to the extent that his doctor had mentioned the possibility of further amputation to a trans-femoral level. The ulcer had persisted for over a year before he was initially fitted with a locking, perforated liner on 27th August 2018 (Figure 2b). When asked what the dermatology clinic advised him, the patient explained "they said the white heavy skin that look like a callous around the wound (Figure 2b), was from moisture. When compared to the initial fitting stage (Figure 2b), at 4 weeks (24th September 2018 - Figure 2c), the ulcer had visibly reduced in size and the wound was no longer suppurating. At 7 weeks (15th October 2018 - Figure 2d), Tissue was granulating and the affected area/ulcer had reduced in size. Over the following 6 weeks, the ulcer reduced in size considerably (1st and 12th November 2018 - Figure 2e and f), before being considered fully healed 13 weeks after initial fitting (28th November 2018 - Figure 2g).
