All subjects were treated with a standardised and disciplined treatment program incorporating cryokinetics and modified training. Muscle firmness ratings, thigh circumference and passive knee flexion range of movement (ROM) measurements, and the unilateral palpation, brush-swipe and tap tests were all found to have substantial to excellent reliability (range: 0.66-1.00). Multiple regression analysis demonstrated that 64 per cent of the variance in the time taken to return to full training could be accounted for by an equation involving the uninjured-injured difference in knee range, relative firmness rating of the injured muscle, difference in circumferences at the suprapatellar border, being able to play on following injury and the time delay before starting treatment.

Presentation for severe hip pain and lower extremity weakness was delayed. Imaging revealed myositis ossificans traumatica compressing the sciatic nerve in the buttock. The patient underwent sciatic nerve decompression with resection of heterotopic calcification, resulting in improvement in pain and left lower extremity function.

  • MRI of Muscle Injury
    MRI OF MUSCLE INJURIES Robert Downey Boutin, M.D. Medical Director, Med-Tel International Skeletal muscle is the single largest tissue in the body, making up 25-50% of one’s total body weight. As radiologists, we image many of the body’s 434 muscles each day -- both intentionally and incidentally. When evaluating the health of muscle, our most sophisticated radiological technique is MRI [1-2]. In this session, we review four topics that aid in understanding and diagnosing injuries of muscle: [I] normal anatomy; [II] MRI indications and technique; [III] pathological conditions; and [IV] differential diagnosis and diagnostic pitfalls. I. NORMAL ANATOMY ORGANIZATION OF MUSCLE Muscle is a complex organ. The basic structural element of skeletal muscle is the muscle fiber. These fibers are grouped into fascicles, and the fascicles are grouped into muscles. Muscles, in turn, are arranged into compartments that are bounded by connective tissue termed fascia. Fascia plays a fundamental role in the pathogenesis of certain muscle disorders (e.g., compartment syndrome, fascial herniation) and influences the extent of others (e.g., spread of tumor and infection). COMPARTMENTS Given that there are hundreds of muscles in the body, the easiest way to conceptualize the location and function of muscles is to become familiar with compartmental anatomy. For example, in the mid-thigh, three compartments are present: anterior (quadriceps and sartorius); posterior (hamstrings); and medial (adductors and gracilis). Four compartments are present in the leg: anterior; lateral; superficial posterior; and deep posterior. II. MRI INDICATIONS & TECHNIQUE INDICATIONS Muscle disorders have a wide variety of causes, treatments, and prognoses.

QESCHICKTER, M.D. (From the Surgioal Pathological Laboratory, Department 07 Surgery, Johns Hopbilcs Hoapital and Uniuereity) INTRODU~TION: EMBRYOLOGY The muscular structures of the body appear very early in the em- bryo and are derived from mesoderm. Within the first month of embi:yonic life the mesoderm spreads out from the hind end of the embryo and separates into a paraxial mass, an intermediate cell mass, and sheets applied to the body wall and primitive digestive tube (Fig. 1).

In association with the splanchnopleure applied to the primitive gut, the muscles of the digestive tube, the heart, and the large blood vessels develop. Tumors are extremely rare in the spinal muscles of the body wall and limbs derived from the paraxial mesoderm. This rarity of tumor formation is probably dependent upon the extremely early differentia- tion of these structures. According to Keith no more new fibers are formed in skeletal muscle after birth, muscular growth henceforth being effected by enlargement of pre-existing fibers. On the other hand, tumors are very common in the smooth muscle of the genito- urinary organs developed from the intermediate cell mass, Here cle- 378 TUMORS OF MUSCLE 379 velopmental processes are delayed and modified in association with the sex physiology which necessitates fairly rapid changes in these structures.
