Arthroscopic versus open shoulder stabilization for recurrent anterior instability: a prospective randomized clinical trial.

BACKGROUND: Arthroscopic stabilization for anterior shoulder instability has been reported to result in a higher rate of recurrent instability compared to traditional open techniques. PURPOSE: To test the null hypothesis that there is no difference in the clinical outcomes in patients with recurrent anterior shoulder instability treated with open or arthroscopic stabilization. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: A consecutive series of 64 patients with recurrent anterior shoulder instability were randomized to receive either arthroscopic or open stabilization by a single surgeon. Magnetic resonance arthrogram studies were obtained preoperatively. These findings were compared to arthroscopic findings. Postoperative evaluations included range of motion, stability, and subjective assessments including Single Assessment Numeric Evaluation, Simple Shoulder Test, Western Ontario Instability Index, and University of California, Los Angeles evaluation. Failure was defined as a second dislocation, recurrent subluxation, or symptoms precluding return to previous work or unrestricted active military duty. RESULTS: Sixty-one patients, 29 who received open stabilization and 32 who received arthroscopic stabilization, were evaluated at a mean of 32 months postoperatively (range, 24-48 months). Patient demographics were equivalent. Preoperative magnetic resonance arthrogram findings were confirmed at arthroscopic examination. The mean operative time was significantly shorter for the arthroscopic repairs (59 vs 149 minutes; P < .001). There were 3 clinical failures (2 open stabilizations, 1 arthroscopic stabilization) by the established criteria. There was a statistically significant improvement from preoperative to postoperative Single Assessment Numeric Evaluation scores in both groups (P < .001). The mean loss of motion (compared to the contralateral shoulder) was greater in the open shoulders. Subjective evaluations were equal in both groups. CONCLUSION: Clinical outcomes after arthroscopic and open stabilization were comparable. Preoperative magnetic resonance arthrograms in shoulders with anterior instability allow an accurate diagnosis of intra-articular abnormality that correlates well with operative findings. Arthroscopic stabilization for recurrent anterior shoulder instability can be performed safely; the clinical outcomes are comparable to those after traditional open stabilization.

Dynamic vs. static-stretching warm up: the effect on power and agility performance.

The purpose of this study was to compare the effect of a dynamic warm up (DWU) with a static-stretching warm up (SWU) on selected measures of power and agility. Thirty cadets at the United States Military Academy completed the study (14 women and 16 men, ages 18-24 years). On 3 consecutive days, subjects performed 1 of the 2 warm up routines (DWU or SWU) or performed no warm up (NWU). The 3 warm up protocols lasted 10 minutes each and were counterbalanced to avoid carryover effects. After 1-2 minutes of recovery, subjects performed 3 tests of power or agility. The order of the performance tests (T-shuttle run, underhand medicine ball throw for distance, and 5-step jump) also was counterbalanced. Repeated measures analysis of variance revealed better performance scores after the DWU for all 3 performance tests (p < 0.01), relative to the SWU and NWU. There were no significant differences between the SWU and NWU for the medicine ball throw and the T-shuttle run, but the SWU was associated with better scores on the 5-step jump (p < 0.01). Because the results of this study indicate a relative performance enhancement with the DWU, the utility of warm up routines that use static stretching as a stand-alone activity should be reassessed.

Diagnosis of medial knee pain: atypical stress fracture about the knee joint.

STUDY DESIGN: Resident's case problem. BACKGROUND: A 19-year-old female, currently enrolled in a military training program, sought medical care for a twisting injury to her right knee. The patient reported her symptoms as similar to an injury she incurred 1 year previously while enrolled in the same military program. The patient's past medical history included a nondepressed fracture of the medial tibial plateau and complete tear of the deep fibers of the medial collateral ligament. DIAGNOSIS: Physical exam revealed nonlocalized anterior and medial knee pain without evidence of internal derangement. Initial knee and tibia radiographs were unremarkable. Referral for orthopedic physician evaluation resulted in concurrence with the therapist's diagnosis and plan of care, and the patient was allowed to continue with limited physical training demands. Despite periods of rest, the patient's symptoms progressively worsened upon attempts to resume running. The examining therapist referred the patient for magnetic resonance imaging (MRI) due to the patient's worsening symptoms, normal radiographs, and concern for a proximal tibia stress fracture. MRI revealed a severe proximal tibial metaphysis stress fracture. DISCUSSION: Stress fractures are commonly encountered injuries in individuals subjected to increased physical training demands. Early evaluation may not yield well-localized findings and may mimic other conditions. Nonmusculoskeletal conditions should be considered in the management of patients with stress fractures. This resident's case problem illustrates the importance of serial physical examinations and collaboration with other healthcare practitioners in the comprehensive assessment and management of a patient with a severe stress fracture.

Comparison of injury rates between cadets with limb length inequalities and matched control subjects over 1 year of military training and athletic participation.

OBJECTIVES: To compare lower-limb overuse injury and low back pain incidence among cadets with and without limb length inequality (LLI) over 1 year of military training and athletic participation. METHODS: A total of 1,100 cadets were screened for LLIs; 126 of 1,100 were identified to have a LLI of > 0.5 cm and were assigned a matched control cadet. Injury rates, numbers of visits to sick call, and numbers of days spent on medical excusal during a 1-year period were then compared for the 252 cadets. RESULTS: There was no difference in prevalence of injury between the groups and no significant differences (p > 0.05) between the groups in injury rates, visits to sick call, or number of days spent on medical excusal. CONCLUSIONS: These findings do not support any increased incidence of injuries in a young, healthy, athletic, military population with mild LLIs, compared with matched control subjects without LLIs, over 1 year.

Operative stabilization of posterior shoulder instability.

BACKGROUND: Symptomatic, traumatic posterior shoulder instability is often the result of a posteriorly directed blow to an adducted, internally rotated, and forward-flexed upper extremity. Operative repair has been shown to provide favorable results. Current arthroscopic techniques with suture anchors and the ability to plicate the capsule using a nonabsorbable suture may provide favorable outcomes with reduced morbidity. PURPOSE: To evaluate the results of operative shoulder stabilization in patients with traumatic posterior shoulder instability. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A consecutive series of patients who underwent arthroscopic or open posterior stabilization for traumatic posterior shoulder instability were evaluated using subjective assessments, physical examinations, the Single Assessment Numeric Evaluation, Rowe score, Simple Shoulder Test, and the Western Ontario Shoulder Instability Index. RESULTS: Between May 1996 and February 2002, 31 shoulders (30 patients) underwent posterior stabilization (19 arthroscopically, 12 open). There were 29 men and 1 woman (mean age, 23 years). Preoperatively, all patients had a distinct traumatic cause for the instability. On physical examination, all patients had posterior apprehension and increased (2+, 3+) posterior load-shift testing. Preoperative radiographs and/or magnetic resonance imaging revealed posterior rim calcification or reverse Bankart lesions in 29 cases (94%). At arthroscopy, posterior labral injuries, reverse Bankart lesions, or humeral head defects were identified. Follow-up averaged 40 months, and the mean duration between injury and surgery was 21 months. The mean Single Assessment Numeric Evaluation, Rowe score, Simple Shoulder Test, and Western Ontario Shoulder Instability Index scores, respectively, for the entire group were 89, 87, 11, and 346; for the open group, they were 81, 80, 10.5, and 594; for the arthroscopic group, they were 92, 92, 11.4, and 190. The Western Ontario Shoulder Instability Index (P < .03) and Rowe score (P < .04) outcomes scores for the arthroscopic group were statistically better than those of the open group. Twenty-nine of 31 shoulders were rated as excellent or good. CONCLUSION: In the case of traumatic posterior shoulder subluxation, posterior lesions of the labrum ("reverse Bankart"), articular edge, and capsule are observed. Surgical treatment addressing these lesions led to satisfactory results for both the open and arthroscopic treated groups. In this study, an arthroscopic technique utilizing suture anchor repair with capsular placation provided the most favorable outcomes.

Identification and management of 2 femoral shaft stress injuries.

STUDY DESIGN: Resident's case problem. BACKGROUND: Although femoral shaft stress fractures in the general population are rare, they are more common among endurance athletes and military recruits. Such individuals presenting with a complaint of hip, thigh, or knee pain should raise suspicion for femoral shaft stress injury. A United States Military Academy cadet presented to West Point's Physical Therapy-Sports Medicine clinic with a complaint of thigh pain related to training with the local marathon team. A second cadet presented to the same clinic during Cadet Basic Training with a complaint of vague but increasing hip, thigh, and knee pain. DIAGNOSIS: Both cadets were suspected of having femoral stress injuries, based on clinical exams, and both diagnoses were confirmed with diagnostic imaging. The 2 cadets were both treated conservatively with progressive rehabilitation once healing was confirmed with radiographs. They both responded favorably to conservative management and returned to full athletic activity at approximately 12 weeks. DISCUSSION: Symptoms from a femoral shaft stress fracture can be vague and mimic those of other etiologies. Providers should consider a broad differential diagnosis, to include femoral shaft stress fracture, when treating endurance athletes and military recruits with anterior hip, thigh, or knee pain. Proper imaging confirms the diagnosis and sequential radiographs assist in rehabilitation planning.

Risk determination for patients with direct access to physical therapy in military health care facilities.

STUDY DESIGN: Nonexperimental, retrospective, descriptive design. OBJECTIVES: This study was designed to ascertain whether direct access to physical therapy placed military health care beneficiaries at risk for adverse events related to their management. BACKGROUND: Military health care beneficiaries have the option at most US military hospitals and clinics to first enter the health care system through physical therapy by direct access, without referral from another privileged health care provider. This level of autonomous practice incurs broad responsibilities and raises concern regarding the delivery of safe, competent, and appropriate patient care administered by physical therapists (PTs) when patients are not first examined and then referred by a physician or other privileged health care provider. While military PTs practice autonomously in a variety of health care settings, they do not work independently within any facility. Military PTs and physicians rely on one another for sharing and collaboration of information regarding patient care and clinical research as warranted. Additionally, military PTs are indirectly supervised by physicians. METHODS AND MEASURES: To reduce provider bias, a retrospective analysis was performed at 25 military health care sites (6 Army, 11 Navy, and 8 Air Force) on patients seen in physical therapy from October 1999 through January 2003. During this 40-month period, 95 PTs (88 military and 7 civilian) were credentialed to provide care throughout the various medical sites. Descriptive statistics were analyzed for total workload, number of new patients seen with and without referral, documented patient adverse events reported to each facility's Risk Management Office, and any disciplinary or legal action against a physical therapist. RESULTS: During the 40-month observation period, 472 013 patient visits were recorded. Of these, 112 653 (23.9%) were new patients, with 50 799 (45.1%) of the new patients seen through direct access without physician referral. Throughout the 40-month data collection period, there were no reported adverse events resulting from the PTs' diagnoses or management, regardless of how patients accessed physical therapy services. Additionally, none of the PTs had their credentials or state licenses modified or revoked for disciplinary action. There also had been no litigation cases filed against the US Government involving PTs during the same period. CONCLUSIONS: The findings from this preliminary study clearly demonstrate that patients seen in military health care facilities are at minimal risk for gross negligent care when evaluated and managed by PTs, with or without physician referral. The significance of these findings with respect to direct access is important for not only our beneficiaries but also our profession and the facilities in which we practice.

Clinical diagnostic accuracy and magnetic resonance imaging of patients referred by physical therapists, orthopaedic surgeons, and nonorthopaedic providers.

STUDY DESIGN: Nonexperimental, retrospective design. OBJECTIVES: This study was designed to compare clinical diagnostic accuracy (CDA) between physical therapists (PTs), orthopaedic surgeons (OSs), and nonorthopaedic providers (NOPs) at Keller Army Community Hospital on patients with musculoskeletal injuries (MSI) referred for magnetic resonance imaging (MRI). BACKGROUND: US Army PTs are frequently the first credentialed providers privileged to examine and diagnose patients with musculoskeletal injuries. Physical therapists assigned at Keller Army Community Hospital have also been credentialed with privileges to order MRI studies for several years. METHODS AND MEASURES: To reduce provider bias, a retrospective analysis was performed on 560 patients referred for MRI over an 18-month period. An electronic review of each patient's radiological profile was performed to assess agreement between clinical diagnosis and MRI findings. Data analyses were performed through descriptive statistics and contingency tables. RESULTS: Analysis on agreement between clinical diagnosis and MRI findings produced a CDA of 74.5% (108/145) for PTs, 80.8% (139/172) for OSs, and 35.4% (86/243) for NOPs. There was a significant difference in CDA between PTs and NOPs (P<.001), and between OSs and NOPs (P<.001). There was no difference in CDA between PTs and OSs (P>.05). CONCLUSIONS: Clinical diagnostic accuracy by PTs and OSs on patients with musculoskeletal injuries was significantly greater than for NOPs, with no difference noted between PTs and OSs.

Compliance wearing a heel lift during 8 weeks of military training in cadets with limb length inequality.

STUDY DESIGN: Retrospective descriptive study. OBJECTIVES: To examine compliance in wearing heel lifts during 8 weeks of military training in cadets identified with limb length inequalities. BACKGROUND: Lack of compliance can be blamed for countless poor outcomes in the medical community. Reported compliance with intervention protocols has been reported to range from 11% to 95%. All 1100 new cadets in the class of 2005 were screened for a limb length inequality One hundred ninety-eight out of 1100 cadets were identified to have a limb length inequality on physical exam and volunteered to participate. Cadets were randomly assigned to a heel lift or control group. Cadets in the heel lift group were instructed to wear a heel lift at all times throughout cadet basic training to attempt to prevent overuse injuries. There was no difference (P > .05) between the heel lift group or the control group on injury rate or excusal days. METHODS AND MEASURES: In an attempt to discern whether the preventive intervention was ineffective by design or if noncompliance was to blame, investigators asked cadets via electronic mail survey to report compliance with heel lift wear as a percentage (0%-100%). RESULTS: Seventy-six out of 99 (76.8%) cadets in the heel lift group responded to the electronic mail survey. Mean reported compliance was 38%. Eighteen cadets reported between 70% and 100% compliance. The remaining 58 cadets reported less than 70% compliance. CONCLUSIONS: Cadet compliance was poor with the use of a heel lift. Physical therapists throughout the military often prescribe heel lifts, therapeutic exercises, or medication and assume good to excellent compliance. This study reminds providers that good compliance should not be assumed in any setting.

Improvement in sit-up performance associated with 2 different training regimens.

STUDY DESIGN: Factorial experimental design. OBJECTIVE: To compare the outcomes of 2 different abdominal muscular fitness training regimens on sit-up performance across sex and abdominal muscular fitness level. BACKGROUND: Researchers suggest that the curl-up, when compared to the sit-up, optimizes the challenge to the abdominal muscles while minimizing shear and compressive forces on the lumbar spine. Although researchers have compared curl-ups and sit-ups in many ways, a comparison of sit-up performance after training programs involving curl-ups and sit-ups has not been investigated. METHODS AND MEASURES: One hundred two active, healthy, college-aged subjects participated in this study. After stratification based upon maximal 2-minute sit-up performance during the orientation session, subjects were randomly assigned to either a training group using curl-up exercise, a training group using sit-up exercise, or a control group. Maximal 2-minute sit-up test performance was measured before and after a 6-week training program. Data were analyzed utilizing an ANOVA model. Significant interactions or main effects were analyzed utilizing Tukey's Honestly Significant Difference Test. Level of significance for all testing was at alpha = 0.05. RESULTS: The sit-up training group improved significantly (P < 0.05). No significant difference in sit-up performance was noted for the curl-up or control groups after the 6-week training program. No statistically significant difference in improvement was noted between sex of subject and level of abdominal muscular fitness of subject. CONCLUSIONS: Short-term sit-up training with the Modified Kersey Method in this population significantly improved a maximum 2-minute sit-up test performance. Curl-up training utilizing the same method did not result in improvement in the number of sit-ups performed in 2 minutes. Specificity of training provides the primary explanation for our findings.

Postural control after a 2-mile run.

Postural control is essential for normal daily activities. It is also a crucial requirement for athletic events and activities. Deterioration in this postural control mechanism is termed postural instability and results in increased postural sway. Decrements in postural sway have been documented following a 15.5-mile run. It remains to be seen whether a shorter distance run will cause a similar decrease in postural control. Therefore, the purpose of this study was to assess the effects of a 2-mile run on postural sway in healthy subjects. Forty-four healthy subjects were assigned to an experimental group (2-mile run) or a control group. Postural sway was measured before and after the run with the Biodex Stability System Overall Stability Index and a clinical balance test called the Military Academy Stance Test. There was a significant before-after run Biodex Stability System Overall Stability Index (p < 0.05) and Military Academy Stance Test index (p < 0.05) increase in the experimental group. There was no significant change for the control group. It was concluded that a 2-mile run does produce a significant increase in postural sway as measured using the Biodex Stability System Overall Stability Index and Military Academy Stance Test.
