Clinical use of fresh, frozen soft tissue allografts.

Fresh frozen allograft tissue provides a good alternative to autogenous tissue for the treatment of patients with symptomatic ligamentous deficiency. While transmission of AIDS and other infectious diseases remains a small possibility, allografts provide the advantages of shorter operative time, small incisions, no damage to a patient's own tissues, and superior usefulness in multiple reconstructions, as well as revision of failed autogenous reconstructions. An independent, critical evaluation of the 4-year results of patients with allograft ACL reconstructions is presented. Issues important in allograft tissue recovery, banking, and intraoperative preparation are reviewed.

Arthroscopic lateral release and the lateral patellar compression syndrome.

An isolated arthroscopic lateral release can provide dramatic relief of anterior knee pain in a select group of patients. We believe this procedure is indicated for patients with lateral patellar compression syndrome without significant chondrosis who have not responded to nonoperative treatment. During the procedure, care must be taken to perform a complete release and to achieve hemostasis. The postoperative rehabilitation emphasizes control of swelling, patellar mobilization, and quadriceps strengthening. We strongly agree with Schonholtz et al who report that the "lateral retinacular release is not a minor procedure and should not be performed simply because it may help and it can't hurt."

Emergency treatment of athletic injuries.

Dental-related injuries continue to occur in high incidence in sporting events. Many of these injuries are preventable although the use of protective mouthguards remains sparce unless the rules of a particular sport explicitly dictate use during participation. Thus many athletes sustain dental-related injuries resulting in deformity and discomfort which may persist throughout their lives. Acute management of these injuries often determines the extent to which the dental disability is recoverable. It is essential that those health care professionals working directly with the athletes during competition reinforce the importance of protection and prevention as well as refine the skills necessary for immediate management of the injuries. Guidelines for management of dental injuries should be established by the team dental consultant and should be reviewed continually by team athletic trainers and team physicians. Often the primary care professional will determine the fate and ultimate recovery from the variety of dental injuries encountered regularly in sports.

Shoulder impingement syndrome. A critical review.

Impingement syndrome is an ill-defined term for a variety of disorders of the shoulder that manifest as anterior shoulder pain, especially during overhead activities. These disorders each have a common pathologic course that includes rotator cuff tendinitis (RCT), and, if untreated, may proceed to cuff rupture. RCT has at least two distinct etiologies. Primary impingement of the supraspinatus tendon on the coracoacromial arch is responsible in the majority of nonathletic cases. Overhead movements in sports are prone to developing secondary mechanical impingement because of an instability pattern that is common in this population. Information from this review and clinical practice permits differentiation of the two distinct etiologies of RCT which is important in treatment planning. Much work still needs to be done in defining the microscopic pathology of RCT.

[Aerobic metabolism of VX and mixed function oxidases].

In our preliminary study, it has been found that VX oxidase exists in the microsome fraction of rat liver and the catalytic reaction needs the participation of molecular oxygen and coenzyme I or II. In this paper, the data showed that deoxycholate inactivated both the mixed function oxidase and VX oxidase. The specific inhibitor proadifen of the mixed function oxidase also profoundly inhibited VX oxidase activity. The complex of VX and cytochrome P-450 exhibited typical difference spectrum of type I. Aniline competitively inhibited the inactivation of VX catalyzed by microsomes. These results indicate that VX is one of the substrates of mixed function oxidase. VX oxidase in the rat liver cells is exactly the mixed function oxidase.

Diagnostic arthroscopy of the knee in children and adolescents.

There is a definite role for arthroscopy in the diagnosis and treatment of problem knees in children and adolescents. In this series, the largest reported to date, significant intraarticular pathology frequently existed in both preadolescent and adolescent groups. Three hundred ten knee arthroscopies in 285 children were reviewed. Preoperative clinical diagnoses were correlated with arthroscopic findings. In preadolescents (12 years old and younger), only 55% of preoperative clinical diagnoses were confirmed at surgery. Thirty-five percent of this group were found to have additional pathology not anticipated preoperatively. In adolescents (13 to 18 years old), 70% of clinical diagnoses were confirmed arthroscopically. Additional pathology was also found on arthroscopic examination in 25% of this group.

Bilateral avascular necrosis of the first metatarsal head in adolescence. A case report.

A 12-year-old girl developed bilateral avascular necrosis of the first metatarsal heads. This condition of the foot seems not to have been previously reported in the literature. Initially, joint debridement and metaphyseal decompression were unsuccessful in relieving pain. Two years later abnormal articular cartilage was surgically removed and the subchondral bone plates were perforated to allow for fibrocartilaginous healing. Pain was diminished, and an excellent clinical result was noted at the follow-up examination two years after the excisional surgery.

Arthroscopy in acute septic knees. Management in pediatric patients.

Arthroscopic evacuation, debridement, and irrigation of acute septic knees in children were effective adjuncts in the treatment of this joint infection. Sixteen knees in 16 pediatric patients were treated with arthroscopic management. Ninety-four percent of the knees had sepsis secondary to Staphylococcus aureus. Two immune-suppressed patients (postrenal transplants) had combined S. aureus and Pseudomonas aeruginosa infections. Twenty-five percent of the patients had a foreign body in the joint that was removed arthroscopically. No postoperative irrigation or drainage systems were used. At an average follow-up period of three years, no evidence of persistent or recurrent infection was noted. Roentgenograms showed no evidence of joint or epiphyseal destruction. Because of the low morbidity associated with the procedure, rapid restoration of joint motion and patient mobility was seen in all patients. Arthroscopic debridement of acute septic knees may be carried out in pediatric patients, given appropriate equipment and arthroscopic skills.

Isolated contracture of the abductor digiti minimi.

A case of isolated contracture of an intrinsic hand muscle, the abductor digiti minimi, after the use of an upper extremity tourniquet is reported. Six cadaver specimens were studied after latex arterial injection. We present an anatomic study and pathomechanical analysis, along with a review of the literature on tourniquet-associated injuries.

Measurement of brachial plexus strain in arthroscopy of the shoulder.

The purpose of this study was to measure the strain on the brachial plexus that results from traction loads applied at various arm positions and to correlate this with visibility through the arthroscope. We mounted strain gauges to the upper trunk, lateral cord, median nerve, and radial nerve of five fresh human cadavers. Each cadaver was placed in a lateral decubitus position, with the head fixed in a neutral position, as for shoulder arthroscopy, and the strain on the plexus was measured as a function of arm position and traction load. A final cadaver was used to determine the accessibility and visibility in the arthroscope at each of the arm positions. At a given flexion angle, increasing abduction is associated with decreasing strain. At a given abduction angle, increasing flexion results in decreased strain. The minimum overall strain was noted at 90 degrees of flexion and 0 degree of abduction. Visibility at this position is limited. We conclude that the ideal arthroscopic position is a combination of two positions that would maximize visibility while minimizing strain to the nerves. These two positions are 45 degrees of forward flexion and 90 degrees of abduction in combination with 45 degrees of forward flexion and 0 degree of abduction.

Objective anterior cruciate ligament testing.

We examined subjects with the Stryker knee laxity tester as part of the clinical examination to determine its usefulness in evaluating the anterior cruciate ligament. We measured 123 athletes with no history of knee injury, as well as 30 patients with ACL injury proven by arthroscopy, and 11 injured patients with intact ACL at arthroscopy. We recorded anterior and posterior tibial displacement at 20 degrees of knee flexion and 20 lbs force in each direction. Anterior laxity and side to side difference correlated with ACL injury; posterior and total AP laxity did not. In normal subjects, mean anterior laxity was 2.5 mm. Only 8% of normal knees had anterior laxity of 5 mm or more. Ten percent of normal subjects had a side to side difference of 2 mm or more. In ACL tears, mean laxity was 8.1 mm, with 94% measuring 5 mm or more. Of the subjects, 89% with unilateral ACL injury had an increase of 2 mm or more on the injured side. Ten of ten acute ACL tears were detected by these criteria, with no false positives. In injured knees with intact ACL, measurements did not differ significantly from normal. We found the objective knee laxity measurement to be a useful complement to clinical knee examination.

Life-threatening clavicular osteomyelitis in two debilitated patients.

Two cases are presented of immunologically compromised patients who developed acute pyogenic clavicular osteomyelitis from direct spread of a contiguous focus. Each patient's condition declined despite antibiotic therapy drainage procedures until survival was in doubt. Both showed striking reversal of their conditions and recovery when an aggressive surgical debridement (total claviculectomy) was performed. Acute pyogenic osteomyelitis of the clavicle is uncommon and rarely reported. The special implications in our patients of this disease of the adapted therapy are discussed.

Halo-clavicle traction.

A case is presented employing a modification of the halo traction technique using clavicle and scapular based pins attached through Hoffmann spacing bars to a standard halo frame. Other techniques that have been employed for fractures and dislocations of the cervical spine are reviewed. The principle advantages are the satisfactory stability it affords and the access the technique provides to the torso. The major problem anticipated of loosening of pins or instability of the apparatus because of the mobile clavicle and scapula did not occur in this patient. The halo-clavicle traction is a needed alternative to more conventional methods of stabilizing the spine.
