Meniscectomy in children and adolescents. A long-term follow-up study.

Thirty-nine patients treated with total meniscectomy younger than 16 years of age were studied. The average follow-up period was 21 years; 71% of the patients reported pain; 68%, stiffness; 54%, swelling; and 41%, giving way. Approximately half the patients described progression of symptoms, but only 27% were asymptomatic. Only 10% noted limitations at work, but 62% had limitations in sports. Twelve percent have had further knee surgery. Forty-nine percent received unsatisfactory subjective/functional ratings. On physical examination, 25% of patients had range of motion loss of greater than 5 degrees, 22% had thigh atrophy of greater than 1 cm, and 20% developed substantial instability. Overall, 27% received unsatisfactory objective ratings. Ninety percent of patients had abnormal roentgenograms. Changes occurred predominantly in the meniscectomized compartment. Forty-four percent of patients had unsatisfactory roentgenographic ratings. Overall ratings indicated that 63% of patients' results rated unsatisfactory. More unsatisfactory results occurred in patients with a follow-up period of longer than 26 years, in those with substantial instability, and in males. Few differences existed between medial and lateral meniscectomies or with increasing durations of symptoms preoperatively.

Patellofemoral joint motion: evaluation by ultrafast computed tomography.

Patellofemoral maltracking is a recognized cause of peripatellar pain. Measurements of the patellofemoral relationships during active motion are not available, and clinicians currently rely on observation, palpation, and static radiographic images to evaluate the symptomatic patient. Ultrafast computed tomography (ultrafast CT) offers objective observations of the dynamic influences of muscle contraction on the patellofemoral joint as the knee is actively moved through a range of motion from 90 degrees flexion to full extension. This study reports our initial observations and establishes a range of normal values so that patients with a clinical suspicion of patellar maltracking may be evaluated.

Distribution and deposition of tritiated cortisol using phonophoresis.

Tritiated cortisol cream was coupled with light-microscopic autoradiography to histologically trace the distribution and deposition of a topical application of cortisol driven in by a therapeutic dose of ultrasound. Fifteen dogs were divided into four distinct groups: Group 1 consisted of two control dogs; Group 2, four dogs that received 10% radioactive cortisol and no ultrasound; Group 3, four dogs that received 5% radioactive cortisol plus ultrasound; and Group 4, five dogs that received 10% radioactive cortisol plus ultrasound. Although the cortisol applied to all dogs was limited to the epidermis, penetration occurred beyond the stratum corneum. The combination of 10% cortisol and ultrasound showed more penetration than 10% cortisol alone (p = .018), suggesting that ultrasound may be useful in the transdermal delivery of cortisol cream. The difference between the penetration of 5% and 10% cortisol when treated with ultrasound was only marginally significant (p = .062).

Injuries in women's gymnastics. The state of the art.

This article takes a three-stage approach to the topic of injuries in women's gymnastics. In the first stage, we review the literature and summarize our current knowledge of injury rates, injuries in specific events, and anatomical location of injuries. In the second, we critically evaluate the relative contributions of these studies in terms of their generalizability, methods, and conceptual approaches. Finally, we present possible directions for future research in the area of women's gymnastic injuries.

Arthrotomography of the glenoid labrum.

Arthrotomography was used to study the glenoid labrum in 8 patients with problems of shoulder instability. In 4 patients, an anterior lesion of the labrum was noted radiographically. The abnormality was confirmed at surgery in 3 of the 4. In 1 of the 3, anterior capsular detachment was also demonstrated radiographically and confirmed surgically. One patient had voluntary posterior subluxation: radiographically, the labrum was normal, and at surgery no abnormalities could be found. The technique, which is simple to perform is described and radiographic anatomy discussed.

Concurrent exercise of dogs using carousel-type treadmill.

To exercise several animals at the same time, a carousel-type treadmill was constructed. Horizontal extensions secured to a motorized central shaft allow six dogs to be run concurrently. To counter the effect of centrifugal force, a rubberized banked running track was built. The track was also designed so that it can be hosed down for easy maintenance. During the past 2 yr, the treadmill has not required any maintenance, and only minimal attention has been necessary on the track.

Nonfatal cervical spine injuries in interscholastic football.

The incidence of nonfatal neck injuries in high school football was determined by performing preseason examinations in 104 active high school players and 75 college freshman candidates. Coaches of all 430 Iowa high schools were asked to recall the number of players experiencing significant neck pain during the season. A detailed questionnaire for each injury was also completed by a sample population of 60 coaches. The incidence of roentgenographic evidence of neck injuries was as high as 32% and was related to years of experience. Injury was most likely to occur to a linebacker or a defensive halfback when they tackled the ball carrier. In the preseason examination, half the players who volunteered a history of significant neck pain had abnormal x-ray films.

Treatment for fixation complications: Femoral neck fractures.

Of 102 hips with femoral neck fracture complications, 75 required major secondary procedures such as total hip replacement, femoral prosthesis, cup arthroplasty, tibial bone grafting, and head and neck resection. The method chosen depended on the specific problem: nonunion, aseptic necrosis, infection, degenerative arthritis, or a failed primary prosthesis. Other factors influencing treatment were the patient's chronological and physiological age, his general health, his life pattern, and the familiarity of the surgeon with the technique and the advantages and disadvantages of the various salvage procedures.

Osteogenesis imperfecta tarda. The morphology of rib biopsies.

Undecalcified bone biopsy specimens from 10 normal individuals and 8 osteogenesis imperfecta patients, 2 to 30 years of age, were analyzed using microradiography as well as ultraviolet, tungsten and polarized light microscope techniques. Biopsies of ribs most reliably reflected the disease process of osteogenesis imperfecta when compared to those biopsies of long bones in the lower extremities deformed enough to require corrective surgery. The rib biopsies consistently revealed that there is a rapid surface turnover of histologically well-organized but osteopenic bone. The high rate of bone turnover is similar to that seen in very young normals but in osteogenesis imperfecta turnover rate does not appear to decline with age. The percentage of surface involved in active new bone formation and in osteoclastic resorption is notably elevated. Excessive osteocyte osteolysis is also characteristic.

Cortical desmoid-like lesion of the proximal humerus and its occurrence in gymnasts (ringman's shoulder lesion).

Eighteen gymnasts were interviewed and examined radiographically for a cortical irregularity of the proximal humerus simulating malignancy. Fifty percent of the gymnasts had the lesion which is considered to be a benign reactive lesion secondary to excessive forces at the pectoralis major insertion to the proximal humerus. All patients were asymptomatic. The lesion is probably unique to gymnasts, particularly those involved with strength moves.
