Spontaneous disappearance of traumatic macular holes in young patients.

PURPOSE: To report the disappearance of traumatic macular hole in three eyes of three patients. METHODS: Clinical data of the patients were reviewed. RESULTS: The three patients were relatively young, ranging in age from 12 to 18 years old. In one eye of each patient, a small traumatic macular hole was observed at the first visit. Visual acuities ranged from 20/100 to 20/40. The macular holes resolved spontaneously 3 to 4 months after the trauma, and final visual acuity improved to 20/20 in all patients. CONCLUSION: Small traumatic macular holes in young patients can resolve spontaneously, and this can be associated with good visual recovery.

Esthetic, biologic and restorative considerations in coronal segment reattachment for a fractured tooth: a clinical report.

Reattachment of a fractured clinical crown involving minimal invasion of the biologic width can be accomplished without conventional ostectomy and crown lengthening so that satisfactory esthetics can be achieved. Adhesive techniques sometimes in conjunction with traditional mechanical retention, such as a post, can be used to reattach the fractured segment. An esthetic result can be obtained with a minimal number of procedures and cost to the patient.

Shoulder disorders in the skeletally immature throwing athlete.

Shoulder injuries are common in young throwing athletes. Most injuries are overuse types related to excessive pitch counts, premature use of breaking pitches, and improper pitching mechanics. These etiologic factors should be recognized early and treated. Prevention of injuries should play a major role in decreasing shoulder injury.

Evaluation and management of shoulder instability in the elite overhead thrower.

The elite throwing athlete places significant forces on the soft-tissue stabilizers of the shoulder with every pitch. Anterior translation forces can be as high as 40% of body weight and distraction forces as high as 80% body weight during the act of throwing. Injury to the static and dynamic stabilizers can lead to significant pain and loss of function in these athletes. To successfully treat the injured thrower, it is important to accurately diagnose the pathologic process. This article reviews the biomechanics of throwing and pathologic processes seen in the elite thrower. We cover the essentials of the history and physical in this population and conclude with a discussion of the various treatment regimens.

Freezing degrees of freedom under stress: kinematic evidence of constrained movement strategies.

The present study investigated the effect of psychological stress imposed on movement kinematics in a computer-simulated batting task involving a backward and forward swing of the forearm. The psychological stress was imposed by a mild electric stimulus following poor performance. Fourteen participants hit a moving ball with a horizontal lever and aimed at a distant target with as much accuracy as possible. The kinematic characteristics appearing under stress were delay of movement initiation, small amplitude of movement and low variability of spatial kinematic events between trials. These features were also found in previous studies in which the experimental task required high accuracy. The characteristic kinematics evident in the present study suggested that the movement strategies adopted by the stressed participants were similar to those that appear under high accuracy demand. Moreover, a correlation analysis between the onset times of kinematic events revealed that temporally consistent movements were reproduced under stress. Taken together, the present findings demonstrated that, under psychological stress, movement strategies tend to shift toward the production of more constrained trajectories, as is seen under conditions of high accuracy demand, even though the difficulty of the task itself does not change.

Training and equipment to prevent athletic head and neck injuries.

Due to the potential for catastrophic neurotraumas and cervical spine injuries in sport, the sports health care professional must take proper measures to prevent such injuries. Strength training of the cervical spine, teaching of proper sporting techniques, and use of protective sports equipment are three primary means of attempting to prevent neurotraumas and cervical spine injuries in sports. There are other avenues to assist in preventing these injuries, such as flexibility programs. The sports health care professional, therefore, must be knowledgeable of the needs of each individual athlete when developing prevention plans.

Shoulder injuries in overhead athletes. The "dead arm" revisited.

The following statements summarize this article: Three distinct categories of Type 2 SLAP lesions exist: (1) anterior, (2) posterior, and (3) combined anteroposterior. Posterior Type 2 SLAP lesions have distinct clinical and anatomic features that distinguish them from anterior Type 2 SLAP lesions. Posterior and combined Type 2 SLAP lesions can be disabling to overhead-throwing athletes because of posterosuperior instability and anteroinferior pseudolaxity. The Jobe relocation test is positive with posterosuperior pain in patients with posterior or combined anterior-posterior Type 2 SLAP lesions and is negative in patients with anterior Type 2 SLAP lesions. Rotator cuff tears are frequently associated with posterior or combined anterior-posterior SLAP lesions, are lesion-location specific, and typically begin from inside the joint as undersurface tears. Repair of posterior SLAP lesions can return overhead-throwing athletes to full overhead athletic functioning. The peel-back mechanism is a likely cause of posterior Type 2 SLAP lesions. To securely repair the posterosuperior labrum to resist torsional peel-back, sulure anchors must be placed posterior to the biceps at the corner of the glenoid. The repair must be protected against external rotation past 0 degree for 3 weeks to avoid undue premature torsional stresses on the repair from the peel-back mechanism. A tight posteroinferior capsule predisposes to Type 2 SLAP lesions in overhead athletes. Shoulders at risk for the dead arm syndrome have a marked loss of internal rotation caused by contracture of the posteroinferior capsule such that less than a 180 degrees arc of rotation is achieved with the arm abducted 90 degrees (the 180 degrees rule). Type 2 SLAP lesions that cause the dead arm syndrome in overhead-throwing athletes are most likely acceleration injuries that occur in late cocking rather than deceleration injuries in follow-through. Rehabilitation of athletes with the dead arm syndrome must include the entire kinetic chain. The root cause of the dead arm syndrome is the Type 2 SLAP lesion.

Volar plate arthroplasty of the proximal interphalangeal joint: a review of ten years' experience.

In 10 years 24 patients had a volar plate advancement arthroplasty for acute or chronic fracture dislocations of the proximal interphalangal joint. Seven were done within 6 weeks of injury, 17 at 6 weeks to 2 years following injury. Final ranges of motion averaged 95 degrees for the former and 78 degrees for the latter group. Radiographs frequently demonstrated a marked remodeling of the disrupted contour of the joint surface of the middle phalanx.

Fracture of the hook of the hamate: report of six cases and the suitability of computerized tomography.

During the last 3 years, six patients with a fracture of the hook of the hamate were seen. All fractures were recognized by the carpal tunnel radiogram, but three were much more clearly demonstrated by computerized tomography of the carpal bones. Immobilization in plaster cast was beneficial in one patient and the other five patients required removal of the fractured fragment. All six patients were able to return to their previous occupations and sport activities.

Traumatic internal carotid artery dissections caused by blunt softball injuries.

This report describes recently treated patients with carotid artery dissection caused by blunt softball injuries, as well as the results of a study of carotid artery trauma in a community. Data obtained through the medical records linkage system used for epidemiologic studies in Olmsted County, MN were used to identify all cases of traumatic internal carotid artery dissection diagnosed from 1987 through 1994. Four patients with traumatic internal carotid artery dissections were identified during the 8-year period under study. In two patients (50%) the carotid dissection was a result of the direct impact of a softball. A 39-year-old-man, who developed transient cerebral ischemic symptoms, and a 35-year-old woman, who developed a painful Horner's syndrome, were struck by a softball on the anterolateral aspect of the neck. Both patients had a low carotid bifurcation. These data suggest that internal carotid artery dissections may be underrecognized sequelae of direct softball injuries to the anterolateral neck. A low carotid bifurcation may be a risk factor for such injuries.

Spiral fracture of the humerus in a ball thrower.

Spiral fractures of the humerus in ball throwers are rare clinical entities that can be confused with pathologic fractures. These fractures have been reported in various throwing sports, arm wrestling, and hand grenade throwing. They most commonly occur in the distal third of the humerus in young, active individuals. They are often preceded by throwing arm pain. Neurologic sequelae are rare. Herein, a case is presented of spiral fracture of the humerus in a softball player, and the assessment and management of these fractures, as well as their etiologic contrast to stress and pathologic fractures, are reviewed.
