This article tries to identify the most frequent osseous lesions in the shoulder complex found in the all day routine of a trauma center or trauma unit. It discusses the clinical diagnosis, the most typical radiological findings and the current concepts of treatment. This report is designed mainly to help the general practitioner outside the hospital community.
Various shoulder injuries can give rise to axillary artery complications. Two such cases were admitted to Tan Tock Seng Hospital late last year. Both were young adult males, who had developed axillary artery thrombosis secondary to shoulder injuries. The following is a short discussion on the common types of shoulder injuries, how they result in axillary artery compromise and a short section on their management and treatment.
OBJECTIVE: The effects of spinal cord injury level on shoulder kinetics during manual wheelchair propulsion were studied. DESIGN: Single session data collection in a laboratory environment. METHODS: Male subjects were divided into four groups: low level paraplegia (n=17), high level paraplegia (n=19), C7 tetraplegia (C7, n=16) and C6 tetraplegia (C6, n=17). Measurements were recorded using a six-camera VICON motion analysis system, a strain gauge instrumented wheel, and wheelchair ergometer. Shoulder joint forces and moments were calculated using the inverse dynamics approach. RESULTS: Mean self-selected propulsion velocity was higher in the paraplegic (low paraplegia=90.7 m/min; high paraplegia=83.4 m/min) than tetraplegic (C7=66.5 m/min; C6=47.0 m/min) groups. After covarying for velocity, no significant differences in shoulder joint moments were identified. However, superior push force in subjects with tetraplegia (C7=21.4 N; C6=9.3 N) was significantly higher than in those with high paraplegia (7.3 N), after covarying velocity. CONCLUSIONS: The superior push force in the tetraplegic groups coupled with weakness of thoraco-humeral depressors increases susceptibility of the subacromial structures to compression. RELEVANCE: Increased vertical force at the shoulder joint, coupled with reduced shoulder depressor strength, may contribute to shoulder problems in subjects with tetraplegia. Wheelchair design modifications, combined with strength and endurance retention, should be considered to prevent shoulder pain development.

Lesions leading to glenohumeral instability may result from acute trauma, atraumatic laxity, or repetitive microtrauma. Athletic activities, especially overhead throwing, may lead to a series of lesions involving the stabilizing structures of the shoulder. The resultant injuries and pathomechanics leading to shoulder symptoms can be classified as primary disease, primary instability, acute traumatic instability, and posterosuperior impingment syndrome. MR imaging with or without intrarticular or intravenous injection of contrast material, along with clinical examination and stress testing, provides valuable preoperative assessment.

To evaluate the injuries in Team Handball 186 male players out of 16 teams were questioned retrospectively at the end of a season. An important difference between practice and competition injuries could be found with an injury rate of 0.8 injuries per 1000 training hours and 13.5 injuries per 1000 playing hours. Injuries were predominant at the lower extremities with ankle injuries being the most frequent injury type. 2/3 of the playing injuries occurred in offense. 1/3 of these offense injuries could be attributed to a counter-attack. These injuries were generally more severe which lead us to a proposition of changing the rules of the game in foul plays in this situation. Elbow injuries in goalkeepers and shoulder injuries in throwers were specific for these types of players. Prophylactic braces were used by nearly 2/3 of the players.
The purpose of the study was to determine the impact of an ergonomic program on perceived stress ratings, injury rates and patient care. After implementation of the ergonomic program, the perceived stress ratings by nursing staff were lower than those ratings at the control hospital and the patients felt more comfortable and secure during patient handling tasks than the patients at the control hospital. Eighteen months after ergonomic interventions, the back and shoulder injuries were reduced, and the lost workdays and restricted/transitional days were decreased. Five years after the implementation, the back and shoulder injuries continued to decrease as well as the lost workdays and restricted days. At the control hospital, the back and shoulder injury rates, the lost workdays, and the restricted days remained stable throughout the study period.

Closed-chain exercise protocols are used extensively in rehabilitation of knee injuries and are increasingly used in rehabilitation of shoulder injuries. They are felt to be preferable to other exercise programs in that they simulate normal physiologic and biomechanical functions, create little shear stress across injured or healing joints, and reproduce proprioceptive stimuli. Because of these advantages, they may be used early in rehabilitation and have been integral parts of "accelerated" rehabilitation programs. The authors review the important components of a closed-chain rehabilitation program and provide examples of specific exercises that are used for rehabilitation of knee and shoulder injuries.
BACKGROUND: Nursing assistants (NAs) working in nursing homes have among the highest back and shoulder injury rates in the US. Incidence, severity, and cost of non-traumatic soft tissue musculoskeletal disorders in the nursing home industry in Washington State are quite high. METHODS: To determine whether resident characteristics data reported on the Health Care Financing Administration Minimum Data Set (MDS) could be used as a surrogate measure of cumulative exposure to physical loads, we conducted an 18-month prospective study in one nursing home. RESULTS: The combined NA injury incidence rate (IR) was 45.8 self-reported back and shoulder injuries per 100 [FTE] workers per year. In general, MDS reported resident characteristics failed to predict risk with the exception of exposure to loss of voluntary leg mobility (OR = 1.11 per person-shifts of exposure, 95% CI [0.97-1.27]), with the highest risk on the day shift (OR = 1.15, 95% CI [0.95-1.40]). CONCLUSIONS: These findings suggest social integration and work organization issues may be more important predictors of back and shoulder injuries in nursing assistants than reported resident characteristics as measured by the MDS.
OBJECTIVE: To assess the ability of plain films and computed tomography scans to show the pattern, displacement, and angulation of scapular neck fractures. To assess the ability of computed tomography to identify concomitant occult shoulder injuries. DESIGN: Masked retrospective radiographic review. SETTING: Level I trauma center. PARTICIPANTS: Three orthopaedic surgeons (two attending physicians and one senior resident) and one musculoskeletal radiology attending physician reviewed the imaging studies of scapula neck fractures in twenty patients treated at our institution. MAIN OUTCOME MEASURES: Kappa analysis of agreement of fracture characteristics and benefits of computed tomography for scapular neck fractures. RESULTS: The mean weighted kappa coefficient for interobserver reliability of fracture displacement was 0.49 when the fractures were assessed by plain films alone, 0.15 when they were assessed by computed tomography scans alone, and 0.35 when they were assessed by plain films and computed tomography scans. The mean weighted kappa coefficients for fracture angulation were 0.30, 0.23, and 0.16, respectively. The mean simple kappa coefficients for fracture classification were 0.81, 0.20, and 0.33, respectively. Concomitant injury to the superior shoulder suspensory complex was seen in 57 percent of cases, including nine clavicle fractures, one coracoid fracture, and three acromion process fractures. The coracoid fracture and two of the acromion process fractures were minimally displaced and seen on computed tomography scans only. CONCLUSION: Scapular neck fracture displacement, angulation, and anatomic classification showed moderate interobserver reliability by plain films but were not enhanced by computed tomography. Computed tomography confused, rather than clarified, the assessment of these characteristics. Computed tomography may be useful to identify associated injuries to the superior shoulder suspensory complex, which can be missed by plain films alone. Routine computed tomography in patients with scapular neck fractures cannot be recommended based on this study. Computed tomography of scapular neck fractures may be useful in selected cases in which intraarticular extension is noted on plain films.

Assessing both physical and mental health is necessary in clinical settings to quantify the scope of disability and to evaluate the effectiveness of treatment programs. Changes in health-related quality of life following physical therapy treatment for many patients with orthopaedic-related diagnoses is not known. The purposes of this study were to describe changes in health-related quality of life between the initial assessment and the time of discharge from physical therapy for the most common orthopaedic diagnoses and to compare the patterns of deficit among diagnostic categories. Patient outcomes in this study were evaluated from a large database generated by the Focus on Therapeutic Outcomes (FOTO) network. Health-related and employment outcomes were described for adult patients who were classified using ICD-9-CM codes. The most common orthopaedic diagnostic categories were sacroiliac sprain, back sprain, low back pain (radiating and nonradiating), neck sprain, neck pain (radiating and nonradiating), adhesive capsulitis of the shoulder, rotator cuff injury, shoulder sprain, knee dislocation, knee sprain, and knee derangement. The primary outcome measure was a 17-item questionnaire (the MOS-17) derived from the RAND 36-Item Health Survey (SF-36) and the 12-item Short Form Health Survey (SF-12). The comparison of each cohort to population norms was made by calculating a standard score on patient data adjusted for age and gender. An effect size was calculated to measure the change in health or employment status between the initial assessment and discharge from physical therapy. For all diagnostic categories, health-related quality of life with respect to norms and employment status showed a consistent pattern of improvement at the time of discharge compared with the initial assessment. There were only small changes in physical function for neck and shoulder diagnostic categories. Nearly all of the diagnostic categories had large reductions in bodily pain. The amount of clinical change in the physical components of health-related quality of life--especially the physical function and role physical domains--differed substantially across specific diagnostic categories. The largest improvements in the physical function occurred for patients with knee dislocation and knee sprain. Patients with knee dislocation also had the largest improvement in role limitations due to physical problems. The design of this study does not permit conclusions about the efficacy of physical therapy. Further study is needed to determine if the finding of different levels of health status improvement across diagnostic categories was due to the nature of the outcome measure, the type of treatments given to each patient, or other confounding variables, like depression or preinjury functional level.
