Alignment control exercise changes lower extremity movement during stop movements in female basketball players.

This study was intended to evaluate a short-term intervention designed to improve the lower extremity alignment with neutral position during stop movements of female basketball players when performing a quick-stop jump shot. In this study, 20 healthy female college basketball players (mean age 20.5 years) participated. The authors monitored two groups for 4 weeks: one which trained (n=10) and one which did not train (n=10). The exercise program emphasized the neutral position of lower extremities for dynamic alignment control; the players avoided the valgus position with their knees. Kinematics analysis with a lower extremity angle in the stop action was performed using three digital video cameras and analyzed using software. Following the intervention exercise program, each subject was re-evaluated at two and four weeks to determine changes in movement patterns during the "sink shot" task. Two-way analysis of variance models were used to determine differences at pre-intervention, at mid-term, and post-intervention. After the 2-week intervention, the trained athletes group made basketball shots with greater change of the lower extremity motion pattern during the stop action than did non-trained athletes (p<0.05). However, no significant differences were found between other data of the 2-week and 4-week intervention groups. Results of this study show that two weeks of training can improve the dynamic alignment control of the lower extremities, as measured using the alignment angle of the coronal plane and the torsion angle of horizontal plane during a stop action.

Radial forearm flaps for reconstruction in hand surgery.

Thirty-seven patients were treated using distally-based island radial forearm flaps. There were 31 men and six women. Reconstructed sites involved the dorsum of the hand (n = 17), the thumb (n = 11), the fingers (n = 5), the first web (n = 3), and the palm (n = 1). Sensory flaps were transferred in 15 cases, osteocutaneous flaps in six, and tendocutaneous flaps in eight. All the flaps survived. There were five donor-site complications, but no functional disturbances. Three patients had symptoms of cold intolerance. There were no radial fractures. In the six cases with osteocutaneous flaps, a mean of 2.6 months (range 2-3) was needed to obtain bony union. Among the eight cases with tendocutaneous flaps, postoperative tenolysis was required in two cases, and finally seven achieved a satisfactory outcome. The mean moving 2-point discrimination of the sensory flaps was 13 mm.

Health education programs may be as effective as exercise intervention on improving health-related quality of life among Japanese people over 65 years.

AIM: The current study was aimed to examine the short-term effects of a 3-month health education program on health-related quality of life using the Short-Form 36. METHODS: Twenty-five Japanese older people aged 65 and older in the health education program were compared with two historical control groups (n = 25 each) undertaking group and resistance exercise interventions and matched by age, sex and body mass index. A series of split-design two-way analyses of variance were conducted for data analysis. RESULTS: Significant improvements were observed in general health and vitality subscales of the Short-Form 36 in the educational program group. Multivariate analyses, adjusted for several confounding factors, revealed that the effects of the three programs were comparable. CONCLUSIONS: The findings suggest that a structured 3-month educational program may be as effective as exercise interventions in improving general health and vitality in a community-dwelling Japanese older population.

Long-term outcomes of flap transfer for treatment of intractable venous stasis ulcers in the lower extremity.

There is little information about long-term outcomes of flap transfer for treatment of venous stasis ulcers in the lower extremity. Eleven patients who underwent free and pedicled flap transfer for treatment of intractable venous stasis ulcers were evaluated retrospectively. The operative procedures consisted of removal of the ulcer and surrounding lipodermatosclerotic tissue, venous stripping, and flap transfer. No ulcer recurrences in the territory of the transferred flap were identified for a mean of 11 years during the follow-up period. However, four patients developed new ulcers in the same leg after the flap transfer at 18, 24, 52, and 81 months. This was probably the result of incomplete excision of surrounding lipodermatosclerotic tissue. Three of four recurrent ulcers were healed with additional procedures. The results of this study indicated that flap transfer combined with venous stripping could lead to long-term healing of venous stasis ulcers. However, incomplete excision of surrounding lipodermatosclerotic tissue caused new ulceration around the transferred flap.

Clinical applications of free soleus and peroneal perforator flaps.

Clinical applications of two free lateral leg perforator flaps are described: a free soleus perforator flap that is based on the musculocutaneous perforator vessels from one of the three main arteries in the proximal lateral lower leg, and a free peroneal perforator flap that is based on the septocutaneous or direct skin perforator vessels from the peroneal artery in the distal and middle thirds of the lateral lower leg. The authors applied free soleus perforator flaps to 18 patients and free peroneal perforator flaps to five patients with soft-tissue defects. The recipient site was the great toe in 14 patients, the hand and fingers in five patients, the leg in two patients, and the upper arm and the jaw in one patient each. The largest soleus perforator flap was 15 x 9 cm, and the largest peroneal perforator flap was 9 x 4 cm. Vascular pedicle lengths ranged from 6.5 to 10 cm in soleus perforator flaps and from 4 to 6 cm in peroneal perforator flaps. All flaps, except for the flap in one patient in the peroneal perforator flap series, survived completely. Advantages of these flaps are that there is no need to sacrifice any main artery in the lower leg, and there is minimal morbidity at the donor site. For patients with a small to medium soft-tissue defect, these free perforator flaps are useful.

Dysvascular lower extremity reconstruction using free flaps with a "Y" configuration of the arterial pedicle.

For patients with a dysvascular lower extremity, free flaps have been transferred by end-to-side anastomosis, in order to maintain peripheral circulation. For such patients, the authors have applied free flap transfers with a "Y" configuration of the arterial pedicle. Eight free flaps with a Y configuration of the arterial pedicle were used in seven patients: latissimus dorsi musculocutaneous flaps in six, and scapular flaps in two. For the former, flaps were harvested with the subscapular and circumflex scapular arteries forming a Y pedicle in three cases, and with the thoracodorsal artery and the branch of the serratus anterior muscle in three. For the scapular flap transfers, the flap was harvested with the subscapular and thoracodorsal arteries forming a Y pedicle in one case, and with the circumflex scapular artery and the descending branch in the other. This procedure was performed for single-artery extremities in two cases. One developed arterial thrombosis of the branch to the foot, but removal of the thrombus and reanastomosis resulted in peripheral blood circulation being maintained. Eventually, all flaps survived. This procedure is indicated in patients with lower-leg reconstruction, especially with vascular disease.

Leydig cell hyperplasia and the maintenance of bone volume: bone histomorphometry and testicular histopathology in 29 male leprosy autopsy cases

This study was conducted to determine if osteoporosis in male leprosy patients is caused by testicular atrophy. Bone volume (BV/TV), trabecular number (TbN), trabecular thickness (TbTh), and trabecular separation (TbSp) were measured in two areas in decalcified paraffin sections of lumbar bones from 29 male leprosy and 6 male nonleprosy autopsy cases. We found significant differences in the average BV/TV measurements among the 7 patients with nodular Leydig cell hyperplasia (BV/TV 12.24%) and the 22 patients without hyperplasia (BV/TV 7.35%) and 6 patients without leprosy (BV/TV 12.98%). Bone volume was maintained in patients with nodular Leydig cell hyperplasia, and we determined no clinical factor other than the Leydig cell hyperplasia that reflected the bone volume. The osteoporosis of male leprosy patients was attributed to secondary gonadal dysfunction due to testicular atrophy, and Leydig cell hyperplasia appears to preserve bone volume.
