The beef forequarter muscle comprises approximately 52% of carcass weight. The objective of this study was to evaluate the physiochemical characteristics and meat color from forequarter muscle of Holstein steers. Fifteen forequarter muscles were trimmed of external connective tissue and fat. An experimental group of eight Holstein steers was assessed using meat color, water-holding capacity, drip loss, and Warner-Bratzler shear force value at the same quality grade. The M. omotransversarius (0.45 kg) had the highest (p<0.05) lightness (L*) value, whereas the M. teres major (0.4 kg) and M. triceps brachii (caput laterale) (0.52 kg) had the lowest (p<0.05) values. The M. semispanitus capitus (1.48 kg), which is a neck muscle, had the highest values for both redness (a*) and yellowness (b*), whereas the lowest (p<0.05) values were for the M. teres major. The M. omotransversarius, M. latissimus dorsi (1.68 kg), and M. rhomboideus (1.2 kg) were ranked high (p<0.05) in water-holding capacity. The drip loss value was the highest for the M. longissimus dorsi thoracis (p<0.05; 1.86 kg), while the M. infraspinatus (2.28 kg), M. supraspinatus (1.38 kg), M. brachiocephalicus (1.01 kg), and M. pectoralis superficialis (1.18 kg) had the lowest (p<0.05). The Warner-Bratzler shear force value indicated that the M. pectoralis profundus (3.39 kg), M. omotransversarius, and M. brachiocephalicus were the toughest (p<0.05), whereas the M. subscapularis (0.86 kg), M. longissimus dorsi thoracis, M. teres major, and M. infraspinatus were the most tender cuts (p<0.05). Here, muscle type explained most of the variability in the forequarter physiochemical characteristics. Thus, our findings suggest that these muscle profile data will allow for more informed decisions when selecting individual muscles to produce value-added products from Holstein steers.

We experienced 17 skeletal muscle transpositions in chest surgery during the past 8 years. There were 3 female and 14 male patients with ranging from 5 to 71 years of age [ average 47.3 Seventeen patients underwent 27 musele flaps : 11 latissimus dorsi, 6 pectoralis major, 6 serratus anterior and 4 other muscles. An average of 2.0 previous operations was performed. Hospitalization averaged 24 days.Follow up ranged from 7 days to 45 months;There were two postoperative deaths; one, 20 days after from operation due to pneumonia and the other, 130 days after from operation due to cor pulmonale.Fifteen patients who were alive after operation had good results at the time of last follow up.

We report the rare case of a 58-year-old woman who was diagnosed with fungal empyema thoracis combined with osteoradionecrosis. After 32 months of home care followed by open window thoracostomy, thoracoplasty with serratus anterior muscle transposition and a latissimus dorsi myocutaneous flap was performed successfully. Although thoracoplasty is now rarely indicated, it is still the treatment of choice for the complete obliteration of thoracic spaces.

We have investigated the clinical results of 33 cases of free flap transfer performed for the soft tissue defects of heel and sole. In donor sites, tensor fascia lata flaps were 4, dorsalis pedis flaps were 10, forearm flaps were 9, and latissimus dorsi flaps were 10. The recipient sites were heel in 22 cases, sole in 7 cases, and heel and sole in 4 cases. In these cases, the postoperative complications, morbidity of donor sites, recovery of sensation, and cosmetic results were evaluated in each flap. All the flaps survived successfully. The free flaps provided excellent functional and cosmetic results. The tensor fascia lata flap was more reliable free flap for the reconstruction of heel and sole defects.

Excision of bullous emphysema or decortication of chronic empyema commonly results in a prolonged air leakage. Prolonged air leakage requires prolonged intercostal drainage, delays recovery, and can be followed complications such as pneumothorax, atelectasis, incomplete expansion of remained lung, secondary infection. To minimize these complications free muscle grafts can be used like a patch to close the opening of visceral pleura and reinforce suture lines without undue tension. From a preliminary study using the latissimus dorsi muscle as a free muscle graft in the rabbit pleural space, viable muscle fibers that seems the result of the process of regeneration can be consistently identified around the degenerating muscle fibers. Voluminous connective tissues and numerous blood vessels are also observed in the peripheral zone. Further studies in that free muscle graft will be sutured with visceral pleura and lung parenchyme will hopefully provide additional information before clinical application.

There were many difficulties in the treatment of extensive, massive, and composite defect in the lower extremity until early 1980's. Recently, microscopic reconstruction of wide soft tissue defect is popularized. But, the combined flap, which requires wide coverage of lower extremity after soft tissue sarcoma excision or traffic accident, is still challenging to the orthopaedic surgeons. We experienced 12 cases of combined scapular and latissimus dorsi flap from 1983 to 1997 in the lower extremity reconstruction of soft tissue defect with satisfactory result. There were no serious donor site complications such as functional disturbance of shoulder joint.

Low back pain has been known as the most frequent musuculoskeletal disorders in modern industrial society and cost by low back pain is increasing mon and more. The asymmetric lifting has been identified as a major risk factor of low back pain. In this study, the muscle activity and muscle exertion level during asymmetric load handling (without trunk flexion) was estimated. The results of normalized MVC measurement were decreased about 16％, 24％, 34％ respectively as the asymmetric angle was $30^{\circ}$, $60^{\circ}$, $90^{\circ}$. From the results of EMG measurement contralateral muscles were more active than ipsilateral muscles. RMSEMG values of right erector spinae muscles were decreased as the work posture went to 90$^{\circ}$ and those of left erector spinae muscles were increased until the asymmetric angle was 40$^{\circ}$ but decreased continually over 40$^{\circ}$. And for seven of subjects, activities of left and right latissimus dorsi muscles were maintained constantly, while for remainer, those were irregular.

High-voltage electrical burn injuries on the scalp often result in scalp and cranial bone necrosis. Repetitive debridements and rich-vascularized flap coverage of the cranium are required. However, despite successful flap coverage, chronic osteomyelitis of cranial bones may occur. Treatment of chronic osteomyelitis of cranial bones is surgical debridement of the necrotic bone with re-coverage by a well-vascularized flap. The latissimus dorsi musculocutaneous flap is suitable not only for coverage of the cranium after the burn injury, but also for treatment of chronic osteomyelitis of the skull.
