TL;DR: A study of the pattern of elbow fractures in children under 15 years of age, during a 5-year period, with special reference to supracondylar humerus fractures, is presented.

TL;DR: In shoulder impingement syndrome, both upward and axial external rotations of the scapula were impaired at the painful arc angle of abduction, which reduces available clearance for the rotator cuff and humeral greater tuberosity as the shoulder is abducted.

TL;DR: Preoperative range of flexion and preoperative varus/valgus tibiofemoral angle affected postoperative range-of-flexion, and the tilt angle of the patella and tilted button may be factors that affect postoperativeRange of Flexion.

TL;DR: Findings indicate that the exercise training program led to a significant increase in lumbar BMD in postmenopausal women with osteoporosis compared with the control, but that the BMD reverted toward a level that was not significantly different from the control with detraining.

TL;DR: It is concluded that both ligaments function to prevent valgus instability, but that the anatomical reasons for their function are different.

TL;DR: Stimulation of new bone formation by micromovement was mainly effective in the early healing phase (4 weeks postoperatively), and it was found that the flexural rigidity correlated with the new bone area in the periosteal region.

TL;DR: Prolonged PGE1 administration produced peri- and intra-tendinous degeneration, providing a cheap, reproducible model of Achilles tendinopathy, which would allow studies of the effects of conservative and surgical management of the condition.

TL;DR: It is necessary to correlate the roentgenographic features, the clinical features, and the histological features to arrive at a definite diagnosis of chondrosarcoma subtypes that behave in a highly aggressive fashion.

TL;DR: Evidence is provided to suggest that, despite the lower increase in BMD produced by me-natetrenone, this agent, as well as etidronate, may have the potential to reduce osteoporotic vertebral fractures in postmenopausal women with osteopOrosis.

TL;DR: An epidemiologic study to determine the prevalence of low back pain in elderly Japanese and to examine the correlation with lumbar lordosis in sagittal plane radiographs found no relationship to age or sex in either group.

TL;DR: The cervical curvature index (Ishihara) and the cervical spine angle (C2–7) were interchangeable, but this interchangeability was lost in the S-shaped cervical spines.

TL;DR: It is shown that gene therapy provides us with new possibilities for the clinical management of orthopedic disorders, and has the great potential of becoming a valuable clinical treatment for orthopedics disorders in the twenty-first century.

TL;DR: The results indicated that the harmful effects of nicotine on the integrity of the intervertebral disc might be mediated by the direct effect of nicotine, or indirectly, by causing vasoconstriction of the vascular network surrounding the interVertebral discs.

TL;DR: The effectiveness of transpedicular calcium phosphate cement injection as a new treatment for osteoporotic compression fracture of vertebrae was evaluated by measuring the compressive strength and the mode of failure in vertebraes experimentally injected with CPC.

TL;DR: A patient in whom synthetic HA blocks implanted in a bone defect of the ilium after the harvesting of full-thickness bone for grafting were extensively absorbed and replaced by newly formed bone 6 years and 7 months after the implantation concludes that HA is biodegradable.

TL;DR: Adjunctive therapy with nonweight-bearing lower extremity exercises appears to be more efficacious for prevention ofLower extremity loss of muscle mass than adjunctive therapyWith walking for obese women with knee OA.

TL;DR: Diagnostic tests consisting of laboratory tests and plain radiography, followed by hip aspiration and sequential use of technetium-99m MDP and gallium-67 scintigraphies, are suitable for differentiation between mechanical loosening and infection of total hip arthroplasty.

TL;DR: The results of this study suggest that immune responses to bone allografts may be reduced by removing the bone marrow and adjacent soft tissues and cellular sources of alloantibody stimulation may have been eliminated by these processes.

TL;DR: Investigating the histopathological and biochemical effects of low-energy extracorporeal shock wave therapy in the healing of tendon injury that may accompany fractures revealed that ESWT may facilitate tendon healing after trauma.

TL;DR: The increased caspase-3 activity, the apoptotic-positive stained DNA fragments, and the electron microscopic findings suggest enhanced programmed cell death in herniated discs, caused by oxygen stress.

TL;DR: Repairs with an artificial composite osteochondral device (COD) is reported, as is biological resurfacing with cultured chondrocytes, indicating that the COD could be a very promising joint repair material.

TL;DR: An implant containing calcium phosphate cement and the anticancer drug, cis-diamminedichloroplatinum (CDDP) was developed and maintained high Pt concentrations at local sites and the bone that formed reinforced the implant.

TL;DR: It is concluded that rotational acetabular osteotomy is efficacious for patients who have preoperative radiographic findings of slight narrowing of the joint space and who could walk for more than 30 min without a cane.

TL;DR: The results of this long-term follow-up study show that high tibial osteotomy for medial compartment osteoarthritis can be effective for as long as 15 years.

TL;DR: An 81-year-old man with late recurrent multiple metastases in skeletal muscles 15 years after radical nephrectomy is reported, with the rarity of muscle metastasis and the unpredictable tendency of this tumor to remain dormant for long periods.

TL;DR: Kinesiological gait analysis is clinically useful for the functional assessment of the severity of spastic walking in cervical myelopathy and is associated with increased walking speed and decreased extension angle of the knee joint after surgery.

TL;DR: It is shown that tumor recurrence is less likely after intralesional tumorcutting with a T-saw than after such cutting with a Gigli saw or scalpel.

TL;DR: When the Dall Miles cable grip device is used for reattachment of the greater trochanter, attention should be paid to the condition of the trochanTERic bed, the tension of the abductor muscles, and to the placement of the cables and the H-shaped grip.

TL;DR: The new coordinate system indicated that the main points of flattening of the foot in patients with hallux valgus were the plantar flexion of the talus and the sinking of the navicular.

TL;DR: Shortening oblique osteotomy of the lateral toes appeared to decrease the rate of implant fracture and should be performed concomitantly with implantation when rheumatoid forefoot deformities are being reconstructed.
