Pectoralis major rupture is a well-recognised but uncommon injury that rarely leads to complications. We present an unusual case where the resultant haematoma following a partial rupture became infected and caused problems with diagnosis. We are only aware of one previous report of this.

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.

Value of myofibrillar protein catabolic rate in Duchenne muscular dystrophy. A study after lower limb surgery.
Previous studies have shown a decreased progression of the course in Duchenne muscular dystrophy (DMD) patients treated by lower limb surgery in early childhood. The use of 3-methylhistidine (3-MH) excretion and 3-MH/creatinine excretion ratio as an appropriate indicator for the myofibrillar protein catabolic rate (MPCR) in muscle disorders is discussed controversially. ⋯ However, the formula for the calculation of the MPCR contains quantities which are not precisely known in DMD or assumed to be constant over the progressive course of DMD. Summarizing MPCR cannot be recommended for the assessment of therapeutic efficacy in DMD.

Case ReportsTotal knee arthroplasty in patients with inherited dwarfism--a report of five knee replacements in two patients with Morquio's disease type A and one with spondylo-epiphyseal dysplasia.
In Morquio's disease and in hereditary spondylo-epiphyseal dysplasia of longer duration, malalignment, instability and unfavourable anatomy are generally the main surgical problems, but as these patients nowadays do not have a reduced life expectancy, it is worthwhile giving them a functional replacement for their severely deformed and painful knees. We report three patients with inherited dwarfism, in whom a replacement of the knee was performed.

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.
