Cystic angiomatosis (hamartous haemolymphagiomatosis) of bone. A clinicopathological study of three cases.

The clinical and radiological features in three cases of cystic angiomatosis of bone are reported. Although these features are generally diagnostic except from histiocytosis X, the definitive diagnosis must be established by a pathological study, preferably of a segment of an involved rib or fibula. The prognosis varies according to the type of clinical presentation-in particular upon whether the lesions are solely skeletal or whether there is extraskeletal visceral involvement. Whereas these last cases may often prove fatal, those with only skeletal involvement have a favourable prognosis: indeed, the cystic bone lesions may regress without any treatment, as occurred in some cases reported in the literature and in two of our three cases.

Surgical treatment of metatarsalgia.

Surgical treatment may be needed where conservative treatment fails in the management of metatarsalgia secondary to pes planus transversus sometimes associated with shortening of the first metatarsal. The author's technique of operation was employed in 85 feet of 45 patients with satisfactory results in 89.4%. The operation consists of a single or double V-shaped osteotomy of the middle metatarsal bones performed in the dorso-plantar plane of the proximal metaphysis. This allows realignment of the metatarsal heads and additional shortening of these bones if necessary. This type of osteotomy is simple and stable with rapid bony union.
