Post-mastectomy breast reconstruction using the inflatable tissue expander.
Breast reconstruction following mastectomy has previously relied on the insertion of a silicone gel implant or the use of a myocutaneous flap. We report the use of an innovation, the inflatable tissue expander, for both immediate and delayed breast reconstruction in 26 patients where soft tissue cover was inadequate to permit the use of the silicone implant. By serial inflation of the tissue expander with saline, sufficient tissue cover was achieved for a second operative placement of a silicone prosthesis of appropriate volume to match the normal breast. To date, 10 patients undergoing delayed reconstruction and 5 of 16 patients with immediate reconstruction have had their final prosthesis inserted, while 3 women are satisfied with the result of the expandable implant and desire no further surgery. Only two technical complications have arisen with loss of the expander in one patient who had had recent radiotherapy and in another the tissue expander was placed much too high on the chest wall. Mechanical failure occurred in three cases where disruption of the seam led to sudden deflation in two and a slow leak from the injection port developed in one. One patient also attempted self-inflation leading to deflation of the tissue expander. The cosmetic results were subjectively and objectively very good with capsular distortion present in only one case. We feel that the inflatable tissue expander is simple and safe to use, may be used for immediate reconstruction without compromising the ablative surgery and should be a choice available to general surgeons for providing safe and cosmetically acceptable reconstructive surgery.

Limited joint mobility in the diabetic foot: relationship to neuropathic ulceration.
Limited joint mobility in the hand is a common manifestation of diabetes with the reported prevalence in insulin-dependent diabetes varying between 8 and 43%. Sixty-two subjects were studied in three groups (controls, diabetic patients without foot problems, and diabetic patients with neuropathic ulceration) to determine whether similar changes occur in the joints of the foot and to examine any possible relationship with neuropathic ulceration. There was a significant impairment of mobility in the range of motion of the sub-talar joint in diabetic patients with ulcers when compared with controls (p = 0.0001) or with the other diabetic patients (p = 0.004). There was a significant correlation between sub-talar range of motion and mobility in other joints of the foot such as at the hallux (r = 0.59, p less than 0.001), or with mobility of the 5th finger (r = 0.41, p less than 0.01). There was also a significant association between the clinical presence of limited joint mobility in the hand, Dupuytren's contracture, and mobility of the sub-talar joint (p less than 0.05). Furthermore, impairment of mobility of the sub-talar joint was greatest on the affected side in those diabetic patients with neuropathic ulceration (p = 0.029). We conclude that the syndrome of limited joint mobility also affects the joints of the feet of diabetic patients and may predispose to ulceration in susceptible neuropathic feet.
