PURPOSE: The success of treatment for mucous cysts of the distal interphalangeal joints of the fingers has been widely variable. The aim of this study was to evaluate the results of surgical treatment of these cysts at our hand unit.

METHODS: Eighty one cysts were treated, with a mean follow up of 18 months(6–24 months). Thirty-one patients (25%) had nail ridging or deformity at presentation. All patients had surgical excision and joint debridement through a dorsal approach.

RESULTS: All patients who underwent surgery had evidence of osteoarthritis with osteophytosis at the time of surgery. No recurrences were noted. Nail ridging resolved after surgery in 55 (67%) digits; the remaining digits had partial improvement or persistent ridging. Five (6%) infections occurred and were treated successfully with antibiotics(4 cases) or debridement,(1 case).6 patients had increased stiffness of the joint and occasional pain or swelling noted in 8 (9.8%) cases.

CONCLUSIONS: Contrary to the published literature, the recurrence rate following excision and joint debridement is very low. Although some patients have decreased range of motion, pain is usually relieved. Some residual sypmtoms might be related to the underlying arthritic process rather than a complication of treatment.

We reviewed the records and radiographs of seven children who presented with knee pain, local tenderness over the medial femoral condyle, and radiological irregularity of the distal medial metaphysis of the femur suggestive of malignancy. In the five patients who had biopsies, histological changes were consistent with musculotendinous avulsion, and the dissection of ten cadavers confirmed the site to be the insertion of part of the adductor magnus. The recognition of this lesion and knowledge of its benign nature may avoid unnecessary anxiety and needless biopsy.

We reviewed 275 cases and calculated the prevalence of bacteriologically or radiologically confirmed acute haematogenous osteomyelitis in children under 13 resident in Greater Glasgow during 1970 to 1990. In the 20-year period there was a fall of over 50%, mainly involving cases of long-bone infection, and those due to Staphylococcus aureus. There was a reduced incidence of complications. The proportion of cases involving long bones decreased from 84% to 57%, and those of Staphylococcus aureus infection from 55% to 31%. These changes, in what is becoming a rare disease, need to be known to ensure early diagnosis and adequate treatment, particularly of subacute non-staphylococcal infection at unusual sites.
