Randomized Controlled Trial Clinical TrialDo Colles' fracture patients benefit from routine referral to physiotherapy following cast removal?
Colles' fracture patients who received physiotherapy immediately following cast removal were compared with patients who received no active therapy following cast removal in a prospective randomised study. Patients who attended physiotherapy achieved significantly greater increases in wrist extension and grip strength after 6 weeks compared to patients who received no active therapy.

Randomized Controlled Trial Clinical TrialTransesophageal echocardiography and clinical features of fat embolism during cemented total hip arthroplasty. A randomized study in patients with a femoral neck fracture.
Forty patients suffering from a medial femoral neck fracture participated in a prospective, randomized study. In 20 patients, the femoral component was cemented using a contemporary technique. In the patient group operated on with the bone vacuum technique, the medullary cavity was drained during the insertion of the stem. ⋯ These distinct hemodynamic changes were not observed in the bone vacuum group. This study was able to show a clearly reduced risk of pulmonary emboli using the bone vacuum cementing technique. The presence of pre-existing disease greatly magnified the clinical relevance of fat embolism.

Comparative StudyTreatment of proximal humerus fracture using multiple intramedullary flexible nails.
A total of 61 patients with a proximal humeral fracture was treated between January 1996 and March 1998 by closed reduction and fracture fixation with intramedullary Prévot (or Nancy) nails. Of these, 28 female and 25 male patients with a mean age of 52 years (range 3-91 years) were reviewed clinically and radiologically with a mean follow-up of 17 months (range 4-30 months). The mean Constant score was 63, the mean Neer score 74 and the mean visual analogue scale (VAS) 73. ⋯ This minimally invasive technique decreases the rate of occurrence of avascular necrosis of the humeral head. However, fractures are not sufficiently stabilised, mainly because of bone loss induced by impaction and osteoporosis. Bone loss remains an unsolved problem, and alternative methods such as the use of bone substitute combined with minimally invasive techniques should be studied.

Intramuscular hemangiomas are rare benign tumors, making up 0.8% of all hemangiomas. They are of interest to the surgeon because their location may present considerable therapeutic challenge since radiographic work-up of the soft- tissue mass by magnetic resonance imaging (MRI) may be suspicious for malignancy. The definitive diagnosis is made by histological study of the surgical and/or biopsy specimen. ⋯ Pain upon activity but also at rest as well as swelling were the major symptoms. The average duration of symptoms was 13 months (range 1 month to 5 years). After a mean follow- up of 3 years and 4 months (range 12 months to 9 years), one of the patients has developed a recurrence; all remaining patients enjoy pain relief without any recurrence.

Chondromyxoid fibroma is a benign, although potentially aggressive tumor, with a cartilage-like matrix, accounting for approximately 1% of all bone tumors. It usually affects the metaphyseal region of long bones of patients in their first or second decade of life. An additional peak of incidence has been observed between 50 and 70 years of age. ⋯ Preferred treatment is complete local excision with tumor-free margins. Intralesional curettage with or without local adjuvants shows a local recurrence rate of approximately 25%. Radiation therapy may be useful in nonresectable cases but bears the well documented risk of radiation-induced malignancies.
