Angiodysplastic lesions of the extremities are very often of great interest for the orthopedist, involving not only bones with length discrepancy, but also joints with hemarthrosis and synovial hypertrophy. We describe 4 patients with cutaneous hemangiomatosis in the lower limb and a concomitant knee arthropathy. Like in other arthropathies, the articular damage is rapidly invasive and leads to progressive damage in the joint if not adequately diagnosed and treated. We treated the 4 patients at different ages, corresponding to different stages of intra-articular involvement. The preoperative management included MRI and diagnostic arthroscopy. All patients underwent an open synovectomy. All our patients were reviewed at a clinical and radiographic follow-up after 10 years. In all patients, the range of motion was improved or at least not worsened after surgery, in spite of a larger extent of cutaneous lesions. X-ray and MRI confirmed clinical data showing no recurrence of the lesion inside the joint and no progression of the articular damage. The clinical outcomes were very good or good in the patients treated early, poorer in the patient operated on at an adult age. The importance of an early and precise diagnosis and of an accurate preoperative planning must be underlined.

Pyle's disease is a rare skeletal dysplasia involving the metaphyses of long bones. To date, spinal involvement has been only rarely described in the literature. To show that spinal changes, which are an expression of the same growth defect of the long bones, are an important and constant sign of the disease in the families studied. The radiographic skeletal changes in five patients have been observed. The pathognomonic metaphyseal widening of tubular bones (known as the 'Erlenmeyer flask sign') was associated with the spinal changes in all cases. Radiographic findings in the spine varied from moderate platyspondyly to the bodies having the appearance of a biconcave lens. This may be attributed to two main causes: (1) a defect in the modelling process of the vertebrae (comparable to that observed in the metaphyses) and (2) chronic pathological fractures secondary to osteoporosis (a typical feature of Pyle's disease). The finding of platyspondyly of varying severity widens the spectrum of radiographic findings in this disease and can assist in diagnosis.

Twenty-nine children with fractures of the anterior tibial spine were reviewed from 3, 5 to 32 years after injury (average period of follow-up 12, 8 years). The aim was to assess long-term results regarding the residual articular function and stability. All patients were evaluated clinically and with the Lysholm and Tegner score. Eight of them were tested by KT 1000 Artrometer and Cybex 350. The overall functional results were quite good but four patients (13.7%) reported a subjective knee instability while a condition of objective laxity (positive anterior drawer and Lachman test) was found in eleven (37,9%). Lysholm and Tegner score were worse in most displaced fractures and in older children (over twelve). The results of strumentaI evaluation had evidenced that the fractured knees showed a statistically significant anterior laxity (p<0.05; sig level: 0 0182) and that the average laxity on the affected side was of 7 millimetres (s d.=1 82 mm) against 4.7 millimetres (s.d.=1 25 mm) on the other side. Only one patient had evident muscular weakness while five patients presented paradoxically greater muscular strength of the fractured limb (functional compensation). No degenerative changes or other pathological findings were found in the affected knee at the follow-up X-ray examination.

... [8] The odontostomatological problems found in patients with Pyle disease are less important than their orthopaedic disorders, but they can stimulate the interest of the clinician to further investigate the possibility of the presence of a bone dysplasia. [8][9][10] Generally, craniofacial bones are only mildly affected. Often, an orthopantomographic radiograph is necessary to diagnose maxillofacial and dental deformities associated with this disorder. ...

... Extrasynovial and intra-synovial locations have been described for joint tumors (8), with intra-synovial locations being more likely to affect cartilage (8). It can be a part of an angiodysplastic lesion of the extremities (Klippel-Trénaunay syndrome) with diffuse (9,10) or localized (11) involvement of the joint. ...
