Differences in Tridimensional Shoulder Kinematics between Asymptomatic Subjects and Subjects Suffering from Rotator Cuff Tears by Means of Inertial Sensors: A Cross-Sectional Study. SENSORS (BASEL, SWITZERLAND) 2023; 23:1012. [PMID: 36679809 PMCID: PMC9864778 DOI: 10.3390/s23021012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 01/04/2023] [Accepted: 01/11/2023] [Indexed: 06/17/2023]
Abstract
Background: The aim of this study was to analyze differences in three-dimensional shoulder kinematics between asymptomatic subjects and patients who were diagnosed with rotator cuff tears. Methods: This cross-sectional study recruited 13 symptomatic subjects and 14 asymptomatic subjects. Data were obtained from three inertial sensors placed on the humerus, scapula and sternum. Kinematic data from the glenohumeral, scapulothoracic and thoracohumeral joints were also calculated. The participants performed shoulder abductions and flexions. The principal angles of movements and resultant vectors in each axis were studied. Results: The glenohumeral joint showed differences in abduction (p = 0.001) and flexion (p = 0.000), while differences in the scapulothoracic joint were only significant during flexion (p = 0.001). The asymptomatic group showed higher velocity values in all sensors for both movements, with the differences being significant (p < 0.007). Acceleration differences were found in the scapula during abduction (p = 0.001) and flexion (p = 0.014), as well as in the sternum only during shoulder abduction (p = 0.022). Conclusion: The results showed kinematic differences between the patients and asymptomatic subjects in terms of the mobility, velocity and acceleration variables, with lower values for the patients.

Three-Dimensional Kinematics during Shoulder Scaption in Asymptomatic and Symptomatic Subjects by Inertial Sensors: A Cross-Sectional Study. SENSORS 2022; 22:s22083081. [PMID: 35459065 PMCID: PMC9029881 DOI: 10.3390/s22083081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 04/13/2022] [Accepted: 04/15/2022] [Indexed: 02/04/2023]
Abstract
Shoulder kinematics is a measure of interest in the clinical setting for diagnosis, evaluating treatment, and quantifying possible changes. The aim was to compare shoulder scaption kinematics between symptomatic and asymptomatic subjects by inertial sensors. Methods: Scaption kinematics of 27 subjects with shoulder symptomatology and 16 asymptomatic subjects were evaluated using four inertial sensors placed on the humerus, scapula, forearm, and sternum. Mobility, velocity, and acceleration were obtained from each sensor and the vector norm was calculated from the three spatial axis (x,y,Z). Shoulder function was measured by Upper Limb Functional Index and Disabilities of the Arm, Shoulder, and Hand questionnaires. One way ANOVA was calculated to test differences between the two groups. Effect size was calculated by Cohen’s d with 95% coefficient Intervals. Pearson’s correlation analysis was performed between the vector norms humerus and scapula kinematics against DASH and ULFI results in symptomatic subjects. Results: The asymptomatic group showed higher kinematic values, especially in the humerus and forearm. Symptomatic subjects showed significantly lower values of mobility for scapular protraction-retraction (Cohen’s d 2.654 (1.819–3.489) and anteriorisation-posteriorisation (Cohen’s d 1.195 (0.527–1.863). Values were also lower in symptomatic subjects for velocity in all scapular planes of motion. Negative correlation showed that subjects with higher scores in ULFI or DASH had lower kinematics values. Conclusion: Asymptomatic subjects tend to present greater kinematics in terms of mobility, velocity, and linear acceleration of the upper limb, and lower humerus and scapula kinematics in symptomatic subjects is associated with lower levels of function.

Abstract
BACKGROUND Shoulder assessment in rehabilitation is focused on kinematic properties due to the variability of symptomatology and clinical expression of shoulder injuries. AIM To perform a receiver operating characteristic analysis of the kinematic variables involved in the functional mobility of the shoulder that allow the identification of discriminating variables between healthy and diseased shoulders during scaption motion. METHOD Analytical cross-sectional study of diagnostic effectiveness was performed in 27 subjects suffering from shoulder damage and 14 asymptomatic controls. Scaption kinematics were evaluated using four inertial sensors placed on the humerus, scapula, forearm and sternum. Three variables (mobility, velocity and acceleration) were obtained from each sensor and the norm of the resultant vector was calculated from each axis. A discriminatory receiver operating characteristic analysis was performed, obtaining the area under the curve, sensitivity and specificity. FINDINGS Significant differences from both the resultant vectors and the axis depended on the body segment analysed were observed. Greater movement velocity and acceleration were observed in the asymptomatic group. Receiver operating characteristic analysis, scapular protraction-retraction mobility distinguished with a diagnostic sensitivity of 83.3% and specificity of 90.9% between asymptomatic and shoulder-damaged patients. These diagnosis values were 83.3% and 72.7% for scapular anterior-posterior velocity. Scapular kinematics, in terms of mobility and velocity, are the key variables in shoulder assessment. INTERPRETATION This study discriminated between patients suffering from shoulder damage and asymptomatic subjects based on shoulder kinematics during scaption motion. Scapular mobility and velocity were found to be key variables in shoulder assessment, along with the humerus.

J Clin Med 2020; 10:jcm10010051. [PMID: 33375716 PMCID: PMC7795404 DOI: 10.3390/jcm10010051] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2020] [Revised: 12/14/2020] [Accepted: 12/21/2020] [Indexed: 01/10/2023] Open
Abstract
(1) Background: Even though rotator cuff tears are the most frequent tendon injuries in adults, the effectiveness of conservatively treated partial-thickness tears still remains a matter of debate. The purpose of this review is to compare corticosteroid injections to other drugs in the treatment of partial rotator cuff tears, focusing on the effectiveness of this therapeutic modality in terms of pain and shoulder functionality. (2) Methods: A systematic electronic search was performed using the PubMed (MEDLINE), EMBASE and Cochrane Library databases. All studies comparing the use of corticosteroids and other infiltrative techniques in the treatment of partial lesions (excluding studies that considered subacromial impingement as inclusion criteria) were pooled, data were extracted and statistically analyzed. (3) Results: Nine studies were included in this systematic review. Those studies, composed by a total of 494 shoulders treated, have been published from 1985 to 2019. All compared techniques have shown a significant improvement over baseline condition. PRP (Platelet Rich Plasma) injections have been shown to be significantly more effective in both functional and pain control only in the long term. (4) Conclusions: None of the techniques prevail indisputably on the others. Anyway, the treatment of partial rotator cuff tears with PRP injections seems to lead to significantly better outcomes in terms of pain and shoulder function in long term follow up. Whereas in short and medium term follow up, PRP injections was superior only in terms of shoulder function. The small number of studies on prolotherapy did not enable us to provide an opinion on the outcomes of this technique.

Three-dimensional in vivo comparative analysis of the kinematics of normal shoulders and shoulders with massive rotator cuff tears with successful conservative treatment. Clin Biomech (Bristol, Avon) 2020; 75:104990. [PMID: 32222472 DOI: 10.1016/j.clinbiomech.2020.104990] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2019] [Revised: 03/11/2020] [Accepted: 03/12/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND This study used in vivo three-dimensional to two-dimensional image registration techniques to compare the glenohumeral kinematics of shoulders with massive rotator cuff tears that were successfully treated conservatively and those of normal shoulders. METHODS Ten patients (age, 67.4 ± 3.63 years) with massive rotator cuff tears on one side and without contralateral tears were enrolled. We performed computed tomography and fluoroscopy on both shoulder joints and created three-dimensional bone models of the humerus and scapula using image registration techniques. We measured the humeral superoinferior translation, angle of humeral external rotation, scapular upward rotation, scapular anteroposterior tilt, and scapular external rotation of the torn shoulders with good range of motion after effective conservative treatment and compared these measurements to those of the contralateral normal shoulders. FINDINGS There was a significant difference in the initial position of the humeral head relative to the glenoid in the tear group; it was 2.0 mm higher than that in the normal group (p < .05). This difference disappeared in the range from 40° to full elevation. The scapular motion of the tear group was significantly more upwardly rotated than that of the normal group: by 9.9° at rest (p < .05) and by 11.6° at terminal elevation (p < .05). No significant differences were detected for humeral head external rotation, scapular anteroposterior tilt, and scapular external rotation between the two groups. INTERPRETATION Kinematics of shoulders with massive cuff tears could not be recovered completely even though the patients had no significant symptoms after successful conservative treatment.

Abstract
BACKGROUND Further studies are required to determine the effectiveness of conservative treatment of partial-thickness rotator cuff tear (PTRCT). Here, we aim to identify the predictors of failure after conservative treatment in a large series of patients with symptomatic PTRCT. METHODS The outcome of conservative treatment in a retrospective cohort of 272 patients with symptomatic PTRCT was evaluated. Demographic, clinical, and radiographic characteristics were extracted from the patients' medical records. Subjective assessments included Constant Shoulder Score (CSS), visual analog scale for pain (VAS pain), activities of daily living (ADL) score, and American Shoulder and Elbow Surgeons (ASES) score, all performed at the first visit. The association of treatment failure with the patient/tear characteristics was assessed. RESULTS The bursal-type PTRCT was associated with male gender (P = .02), earlier referral of the patients (P = .001), more nonsteroidal anti-inflammatory drug consumption (P = .004), more positive painful arc syndrome (P = .006), and lower CSS (P < .001). These symptoms subsided completely or considerably in 172 (63.2%) patients after the conservative treatment, from which the disease relapsed in 21 (12.2%) patients at the mean follow-up of 22.2 ± 8.8 months. The symptoms led to surgery in the remaining 100 (36.8%) patients. The failure rate of conservative treatment was significantly higher in the dominant injuries (P = .015), the bursal type (P < .001), and tears involving more than 50% of the depth of the tendon (P < .001). CONCLUSION The bursal type tear, dominant tears, and tears involving >50% of the tendon depth are factors capable of predicting failure after conservative management of PTRCT.

Abstract
Background Reduced range of motion in the shoulder can be a source of functional limitation. The use of inertial sensors to quantify movement in addition to more common clinical assessments of the shoulder may allow clinicians to understand that they are potentially unnoticed by visual identification. The aim of this study was to generate an explanatory model for shoulder abduction based on data from inertial sensors. Method A cross-sectional study was carried out to generate an explanatory model of shoulder abduction based on data from inertial sensors. Shoulder abduction of thirteen older adults suffering from shoulder dysfunction was recorded with two inertial sensors placed on the humerus and scapula. Movement variables (maximum angular mobility, angular peak of velocity, peak of acceleration) were used to explain the functionality of the upper limb assessed using the Upper Limb Functional Index (ULFI). The abduction movement of the shoulder was explained by six variables related to the mobility of the shoulder joint complex. A multivariate analysis of variance (MANOVA) was used to explain the results obtained on the functionality of the upper limb. Results The MANOVA model based on angular mobility explained 69% of the variance of the ULFI value (r-squared = 0.69). The most relevant variables were the abduction-adduction of the humerus and the medial/lateral rotation of the scapula. Conclusions The method used in the present study reveals the potential importance of the analysis of the scapular and humeral movements for comprehensive evaluation of the upper limb. Further research should include a wider sample and may seek to use this assessment technique in a range of potential clinical applications.

Abstract
BACKGROUND This study compared imaging findings of blood flow changes between symptomatic rotator cuff tear (RCT) and frozen shoulder (FS) by using 3-dimensional dynamic magnetic resonance imaging (MRI) to determine the clinical characteristics of symptomatic RCT. METHODS The 2 study groups comprised 31 symptomatic RCT patients who underwent arthroscopic rotator cuff repair and 30 patients with FS. We denoted abnormal blood flow detected around the glenohumeral joint as the burning sign (BS). We evaluated the characteristics of dynamic MRI and compared them between BS-positive and BS-negative patients in the RCT group. RESULTS All members of the FS group showed the BS. Conversely, the incidence of the BS in RCT patients was 53% (16 of 31). The BS in RCT and FS patients was observed in the rotator interval in 16 shoulders, in the axillary pouch in 3 shoulders (P < .01), and in the intertubercular groove in 10 RCT and 12 FS patients. In the RCT group, 16 patients with BS had a statistically significantly higher Numeric Rating Score at rest (P = .0005) and in motion (P = .04) than the 15 patients without BS and exhibited a higher rate of small and medium tears and a higher rate of shoulder contracture. CONCLUSION Dynamic MRI of symptomatic RCT (53.3%) highlighted abnormal vascularization around the glenohumeral joint, which may be associated with pain and contracture in RCT as in FS.

Abstract
Chronic rotator cuff (RC) tears are characterized by retraction, fat accumulation, and atrophy of the affected muscle. These features pose an intractable problem for surgical repair and subsequent recovery, and their prevention may be easier than reversal. Using an established ovine model, we tested the hypothesis that inhibition of the protease calpain mitigates m. infraspinatus atrophy by preservation of the myofibers' structural anchors in the sarcolemma (the costameres). Already 2 weeks of distal tendon release led to a reduction in muscle volume (-11.6 ± 9.1 cm3 , P = 0.038) and a 8.3% slow-to-fast shift of the fiber area (P = 0.046), which were both entirely abolished by chronic local administration of the calpain inhibitor calpeptin alone, and in combination with sildenafil. Calpain inhibition blunted the retraction of the muscle-tendon unit by 0.8-1.0 cm (P = 0.020) compared with the control group, and prevented cleavage of the costameric protein talin. Calpain 1 and 2 protein levels increased in the medicated groups after 4 weeks, counteracting the efficacy of calpeptin. Hence atrophic changes emerged after 4 weeks despite ongoing treatment. These findings suggest that the early muscular adaptations in the specific case of RC tear in the ovine model are indistinguishable from the atrophy and slow-to-fast fiber transformation observed with conventional unloading and can be prevented for 2 weeks. Concluding, calpain is a potential target to extend the temporal window for reconstruction of the ruptured RC tendon before recovery turns impossible.

Abstract
INTRODUCTION Excessive thoracic kyphosis is considered a predisposing factor for shoulder pain, though there is uncertainty about the nature of the relationship between shoulder pain and thoracic spine posture. The aim of this systematic review was to investigate the relationship between thoracic kyphosis and shoulder pain, shoulder range of motion (ROM) and function. METHODS Two reviewers independently searched eight electronic databases and identified relevant studies by applying eligibility criteria. Sources of bias were assessed independently by two reviewers using a previously validated tool (Ijaz et al., 2013). Data were synthesised using a level of evidence approach (van Tulder et al., 2003). RESULTS Ten studies were included. Four studies were rated as low risk of bias, three at moderate risk of bias and three at high risk of bias. There is a moderate level of evidence of no significant difference in thoracic kyphosis between groups with and without shoulder pain. One study at high risk of bias demonstrated significantly greater thoracic kyphosis in people with shoulder pain (p < 0.05). There is a strong level of evidence that maximum shoulder ROM is greater in erect postures compared to slouched postures (p < 0.001), in people with and without shoulder pain. CONCLUSIONS Thoracic kyphosis may not be an important contributor to the development of shoulder pain. While there is evidence that reducing thoracic kyphosis facilitates greater shoulder ROM, this is based on single-session studies whose long-term clinical relevance is unclear. Higher quality research is warranted to fully explore the role of thoracic posture in shoulder pain.

Abstract
Persistent muscle atrophy in the chronically torn rotator cuff is a significant obstacle for treatment and recovery. Large atrophic changes are predictive of poor surgical and nonsurgical outcomes and frequently fail to resolve even following functional restoration of loading and rehabilitation. New insights into the processes of muscle atrophy and recovery gained through studies in developmental biology combined with the novel tools and strategies emerging in regenerative medicine provide new avenues to combat the vexing problem of muscle atrophy in the rotator cuff. Moving these treatment strategies forward likely will involve the combination of surgery, biologic/cellular agents, and physical interventions, as increasing experimental evidence points to the beneficial interaction between biologic therapies and physiologic stresses. Thus, the physical therapy profession is poised to play a significant role in defining the success of these combinatorial therapies. This perspective article will provide an overview of the developmental biology and regenerative medicine strategies currently under investigation to combat muscle atrophy and how they may integrate into the current and future practice of physical therapy.

Abstract
Background The purpose of this study was to examine the impact of rotator cuff (RC) decompression and/or repair on post-operative ROM in patients with pre-operative restricted passive motion who had undergone arthroscopic subacromial debridement and/or rotator cuff repair. Potential predictors of ROM recovery such as age, sex, mechanism of injury, type of surgery, presence of an endocrine illness and having an active Worker Compensation claim related to the shoulder were explored. Methods A retrospective analysis of prospectively collected data was performed. Pre-operative stiffness measured intra-operatively was defined as flexion of < =100° or external rotation of < =30° under anesthesia. Patients who received manipulation under anesthesia or required capsular release were excluded. Results Two hundred and eighteen patients met the criteria for having stiffness under anesthesia. Twenty six patients had stiffness in both directions, 19 patients had isolated restricted flexion and 173 had isolated restricted external rotation. At six months post-operatively, a statistically significant improvement was observed on average in all disability measures (P < 0.0001). The ROM improved on average in the restricted direction at 6 months (p < 0.0001). Older age had a negative impact on recovery of external rotation (F2,216 = −5.78, p = 0.02). Being a female, having a traumatic event, having a RC repair, or suffering from an endocrine illness such as diabetes, did not have a negative impact on recovery. Patients with an active work-related compensation claim showed an inferior recovery of flexion (F2,216 = −8.76, p = 0.003). Conclusion Patients with RC pathology and concomitant stiffness showed significant improvement in ROM at six months following RC decompression or repair without the need for formal capsular releases or the performance of manipulation under anesthesia. Older patients and those with active Workers Compensation claim showed an inferior recovery in isolated directions.

Abstract
PURPOSE To examine the role of an advanced-practice physiotherapist (APP) with respect to (1) agreement with an orthopaedic surgeon on diagnosis and management of patients with shoulder problems; (2) wait times; and (3) satisfaction with care. METHODS This prospective study involved patients with shoulder complaints who were referred to a shoulder specialist in a tertiary care centre. Agreement was examined on seven major diagnostic categories, need for further examination and surgery, and type of surgical procedure. Wait times were compared between the APP- and surgeon-led clinics from referral date to date of initial consultation, date of final diagnostic test, and date of confirmed diagnosis and planned treatment. A modified and validated version of the Visit-Specific Satisfaction Instrument assessed satisfaction in seven domains. Kappa (κ) coefficients and bias- and prevalence-adjusted kappa (PABAK) values were calculated, and strength of agreement was categorized. Wait time and satisfaction data were examined using non-parametric statistics. RESULTS Agreement on major diagnostic categories varied from 0.68 (good) to 0.96 (excellent). Agreement with respect to indication for surgery was κ=0.75, p<0.001; 95% CI, 0.62-0.88 (good). Wait time for APP assessment was significantly shorter than wait time for surgeon consultation at all time points (p<0.001); the surgeon's wait time was significantly reduced over 3 years. High satisfaction was reported in all components of care received from both health care providers. CONCLUSIONS Using experienced physiotherapists in an extended role reduces wait times without compromising patient clinical management and overall satisfaction.

Abstract
BACKGROUND Shoulder pain is a very common symptom. Disorders of the rotator cuff tendons due to wear or tear are among the most common causes of shoulder pain and disability. Magnetic resonance imaging (MRI), magnetic resonance arthrography (MRA) and ultrasound (US) are increasingly being used to assess the presence and size of rotator cuff tears to assist in planning surgical treatment. It is not known whether one imaging method is superior to any of the others. OBJECTIVES To compare the diagnostic test accuracy of MRI, MRA and US for detecting any rotator cuff tears (i.e. partial or full thickness) in people with suspected rotator cuff tears for whom surgery is being considered. SEARCH METHODS We searched the Cochrane Register of Diagnostic Test Accuracy Studies, MEDLINE, EMBASE, and LILACS from inception to February 2011. We also searched trial registers, conference proceedings and reference lists of articles to identify additional studies. No language or publication restrictions were applied. SELECTION CRITERIA We included all prospective diagnostic accuracy studies that assessed MRI, MRA or US against arthroscopy or open surgery as the reference standard, in people suspected of having a partial or full thickness rotator cuff tear. We excluded studies that selected a healthy control group, or participants who had been previously diagnosed with other specific causes of shoulder pain such as osteoarthritis or rheumatoid arthritis. Studies with an excessively long period (a year or longer) between the index and reference tests were also excluded. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data on study characteristics and results of included studies, and performed quality assessment according to QUADAS criteria. Our unit of analysis was the shoulder. For each test, estimates of sensitivity and specificity from each study were plotted in ROC space and forest plots were constructed for visual examination of variation in test accuracy. Meta-analyses were performed using the bivariate model to produce summary estimates of sensitivity and specificity. We were unable to formally investigate potential sources of heterogeneity because of the small number of studies. MAIN RESULTS We included 20 studies of people with suspected rotator cuff tears (1147 shoulders), of which six evaluated MRI and US (252 shoulders), or MRA and US (127 shoulders) in the same people. Many studies had design flaws, with the potential for bias, thus limiting the reliability of their findings. Overall, the methodological quality of the studies was judged to be low or unclear. For each test, we observed considerable heterogeneity in study results, especially between studies that evaluated US for the detection of full thickness tears and studies that evaluated MRA for the detection of partial thickness tears. The criteria for a positive diagnostic test (index tests and reference standard) varied between studies.Meta-analyses were not possible for studies that assessed MRA for detection of any rotator cuff tears or partial thickness tears. We found no statistically significant differences in sensitivity or specificity between MRI and US for detecting any rotator cuff tears (P = 0.13), or for detecting partial thickness tears (P = 1.0). Similarly, for the comparison between MRI, MRA and US for detecting full thickness tears, there was no statistically significant difference in diagnostic performance (P = 0.7). For any rotator cuff tears, the summary sensitivity and specificity were 98% (95% CI 92% to 99%) and 79% (95% CI 68% to 87%) respectively for MRI (6 studies, 347 shoulders), and 91% (95% CI 83% to 95%) and 85% (95% CI 74% to 92%) respectively for US (13 studies, 854 shoulders). For full thickness tears, the summary sensitivity and specificity were 94% (95% CI 85% to 98%) and 93% (95% CI 83% to 97%) respectively for MRI (7 studies, 368 shoulders); 94% (95% CI 80% to 98%) and 92% (95% CI 83% to 97%) respectively for MRA (3 studies, 183 shoulders); and 92% (95% CI 82% to 96%) and 93% (95% CI 81% to 97%) respectively for US (10 studies, 729 shoulders).Because few studies were direct head-to-head comparisons, we could not perform meta-analyses restricted to these studies. The test comparisons for each of the three classifications of the target condition were therefore based on indirect comparisons which may be prone to bias due to confounding. AUTHORS' CONCLUSIONS MRI, MRA and US have good diagnostic accuracy and any of these tests could equally be used for detection of full thickness tears in people with shoulder pain for whom surgery is being considered. The diagnostic performance of MRI and US may be similar for detection of any rotator cuff tears. However, both MRI and US may have poor sensitivity for detecting partial thickness tears, and the sensitivity of US may be much lower than that of MRI. The strength of evidence for all test comparisons is limited because most studies were small, heterogeneous and methodologically flawed, and there were few comparative studies. Well designed studies that directly compare MRI, MRA and US for detection of rotator cuff tears are needed.

The impact of depression and anxiety on self-assessed pain, disability, and quality of life in patients scheduled for rotator cuff repair. J Shoulder Elbow Surg 2013; 22:1160-6.

Abstract
BACKGROUND Psychological status may be an important predictor of outcome and patient satisfaction after treatment for rotator cuff disease. Few prior studies have considered these factors. The objective of the study was to investigate the prevalence of psychological distress and its effect on self-assessed pain, disability, and health-related quality of life in patients scheduled for rotator cuff repair. MATERIALS AND METHODS We assessed 107 consecutive patients preoperatively using the Hospital Anxiety and Depression Scale (HADS); visual analog scale pain score; American Shoulder and Elbow Surgeons (ASES) scale; Korean Shoulder Scale (KSS); and World Health Organization Quality of Life Scale, Abbreviated Version (WHOQOL-BREF). Preoperative demographic, clinical, and radiologic parameters were also evaluated. RESULTS Of the patients, 28 (26.2%) had depression and 25 (23.4%) had anxiety. The HADS depression score was positively correlated with the visual analog scale pain score (P = .048) and negatively correlated with the ASES, KSS, and WHOQOL-BREF scores (P = .005, P = .004, and P < .0001, respectively). The HADS anxiety score was negatively correlated with the ASES, KSS, and WHOQOL-BREF scores (P = .034, P = .037, and P < .0001, respectively). On multivariate analysis with a linear regression model, the HADS depression score was an independent predictor of ASES, KSS, and WHOQOL-BREF scores (P = .02, P = .005, and P = .001, respectively). CONCLUSION Depression and anxiety had a negative impact on self-assessed outcome measurements in patients scheduled for rotator cuff repair. Depression was a strong predictor of functional disability and health-related quality of life. Our results suggest that preoperative psychological status may influence postoperative outcome after rotator cuff repair and thus is an essential part of preoperative assessment.

Abstract
Many musculoskeletal disorders (MDs) are associated with irreversible bone and cartilage damage; this is particularly true for osteoarthritis (OA). Therefore, a clinical need exists for modalities which can detect OA and other MDs at early stages. Optical coherence tomography (OCT) is an infrared-based imaging, currently FDA approved in cardiology and ophthalmology, which has a resolution greater than 10 microns and acquisition rate of 120 frames/second. It has shown feasibility for imaging early OA, identifying changes prior to cartilage thinning both in vitro and in vivo in patients and in OA animal models. In addition, OCT has shown an ability to identify early rheumatoid arthritis (RA) and guide tendon repair, but has the potential for an even greater impact. Clinical trials in OA are currently underway, as well as in several other MDs.

Abstract
The etiology of rotator cuff disease is likely multifactorial, including age-related degeneration and microtrauma and macrotrauma. The incidence of rotator cuff tears increases with aging with more than half of individuals in their 80s having a rotator cuff tear. Smoking, hypercholesterolemia, and genetics have all been shown to influence the development of rotator cuff tearing. Substantial full-thickness rotator cuff tears, in general, progress and enlarge with time. Pain, or worsening pain, usually signals tear progression in both asymptomatic and symptomatic tears and should warrant further investigation if the tear is treated conservatively. Larger (>1-1.5 cm) symptomatic full-thickness cuff tears have a high rate of tear progression and, therefore, should be considered for earlier surgical repair in younger patients if the tear is reparable and there is limited muscle degeneration to avoid irreversible changes to the cuff, including tear enlargement and degenerative muscle changes. Smaller symptomatic full-thickness tears have been shown to have a slower rate of progression, similar to partial-thickness tears, and can be considered for initial nonoperative treatment due to the limited risk for rapid tear progression. In both small full-thickness tears and partial-thickness tears, increasing pain should alert physicians to obtain further imaging as it can signal tear progression. Natural history data, along with information on factors affecting healing after rotator cuff repair, can help guide surgeons in making appropriate decisions regarding the treatment of rotator cuff tears. The management of rotator cuff tears should be considered in the context of the risks and benefits of operative versus nonoperative treatment. Tear size and acuity, the presence of irreparable changes to the rotator cuff or glenohumeral joint, and patient age should all be considered in making this decision. Initial nonoperative care can be safely undertaken in older patients (>70 years old) with chronic tears; in patients with irreparable rotator cuff tears with irreversible changes, including significant atrophy and fatty infiltration, humeral head migration, and arthritis; in patients of any age with small (<1 cm) full-thickness tears; or in patients without a full-thickness tear. Early surgical treatment can be considered in significant (>1 cm-1.5 cm) acute tears or young patients with full-thickness tears who have a significant risk for the development of irreparable rotator cuff changes.

Abstract
BACKGROUND Few reports have so far evaluated the possible restrictions of activities of daily living (ADL) in patients with asymptomatic rotator cuff tears (RCTs). The purpose of this study was to examine the effects of RCTs, including shoulders without pain, on ADL in the general population. METHODS We performed medical checkups on 462 individuals (924 shoulders). All participants completed a questionnaire regarding their background and medical history. We then assessed their shoulder functions with the Simple Shoulder Test (SST) and performed US (US) examinations of both shoulders to diagnose RCTs. We divided participants into tear and nontear groups and performed statistical analysis to compare total SST scores and each SST item between groups. Furthermore, we performed the same examinations for participants identified as having shoulders without pain. RESULTS Among participants, those in the tear group showed significantly lower total SST scores than those in the nontear group. After examining each SST item, a significant difference was observed regarding the ability to sleep comfortably and to lift 3.6 kg to shoulder level. In shoulders without pain, the tear group showed significantly lower total SST scores than the nontear group. A significant difference was observed only regarding the ability to lift 3.6 kg to shoulder level. CONCLUSIONS In the general population, ADL were restricted in participants with RCTs; they experienced night pain in the shoulder and muscle weakness during shoulder elevation. Furthermore, participants with RCTs, even if the condition itself did not induce any pain, tended to experience muscle weakness during shoulder elevation, thus resulting in restrictions of ADL.

Abstract
Background Rotator-cuff pathology is the most common cause of pain and disability in the shoulder. Examining the combined effect of biological and societal factors on disability would potentially identify existing differences between men and women with rotator cuff pathology which would help to provide suggestions for better models of care. Purpose of this study was to determine the overall differences in disability between men and women and to examine the relationship between factors that represent sex (biological factors) and gender (non-biological factors) with disability and satisfaction with surgical outcome 6 months after rotator cuff surgery. Methods Patients with impingement syndrome and/or rotator cuff tear who underwent rotator cuff surgery completed the Western Ontario Rotator Cuff (WORC) index, the American Shoulder & Elbow Surgeons (ASES) assessment form, and the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) outcome measures prior to surgery and 6 months post-operatively. They also rated their satisfaction with surgery at their follow-up appointment. Results and Discussion One hundred and seventy patients entered into the study (85 men and 85 women). One hundred and sixty patients (94%) completed the 6-month assessment. Women reported more disability both prior to and after surgery. Disability at 6 months was associated with pain-limited range of motion, participation limitation, age and strength. Satisfaction with surgery was associated with level of reported disability, expectations for improved pain, pain-limited range of motion and strength. Conclusions The results of this study indicate that women with rotator cuff pathology suffer from higher levels of pre- and post-operative disability and sex and gender qualities contribute to these differences. Gender-sensitive approach will help to identify existing differences between men and women which will help to promote more effective and tailored care by health professionals.

Abstract
The etiology of rotator cuff tendinopathy is multi-factorial, and has been attributed to both extrinsic and intrinsic mechanisms. Extrinsic factors that encroach upon the subacromial space and contribute to bursal side compression of the rotator cuff tendons include anatomical variants of the acromion, alterations in scapular or humeral kinematics, postural abnormalities, rotator cuff and scapular muscle performance deficits, and decreased extensibility of pectoralis minor or posterior shoulder. A unique extrinsic mechanism, internal impingement, is attributed to compression of the posterior articular surface of the tendons between the humeral head and glenoid and is not related to subacromial space narrowing. Intrinsic factors that contribute to rotator cuff tendon degradation with tensile/shear overload include alterations in biology, mechanical properties, morphology, and vascularity. The varied nature of these mechanisms indicates that rotator cuff tendinopathy is not a homogenous entity, and thus may require different treatment interventions. Treatment aimed at addressing mechanistic factors appears to be beneficial for patients with rotator cuff tendinopathy, however, not for all patients. Classification of rotator cuff tendinopathy into subgroups based on underlying mechanism may improve treatment outcomes.

Abstract
In order to compare the outcome from surgical repair and physiotherapy, 103 patients with symptomatic small and medium-sized tears of the rotator cuff were randomly allocated to one of the two approaches. The primary outcome measure was the Constant score, and secondary outcome measures included the self-report section of the American Shoulder and Elbow Surgeons score, the Short Form 36 Health Survey and subscores for shoulder movement, pain, strength and patient satisfaction. Scores were taken at baseline and after six and 12 months by a blinded assessor. Nine patients (18%) with insufficient benefit from physiotherapy after at least 15 treatment sessions underwent secondary surgical treatment. Analysis of between-group differences showed better results for the surgery group on the Constant scale (difference 13.0 points, p - 0.002), on the American Shoulder and Elbow surgeons scale (difference 16.1 points, p < 0.0005), for pain-free abduction (difference 28.8 degrees , p = 0.003) and for reduction in pain (difference on a visual analogue scale -1.7 cm, p < 0.0005).

Abstract
Risk factors for revision surgery and hospitalization following rotator cuff repair (RCR) have not been clearly identified. We hypothesized patient factors and surgeon and hospital volume independently contribute to the risk of readmission within 90 days and revision RCR within one year. Using the SPARCS database, we included patients undergoing primary RCR in New York State between 1997 and 2002. These patients were tracked for readmission within 90 days and revision RCR within 1 year. A generalized estimating equation was developed to determine whether patient factors, surgeon volume, or hospital volume were independent risk factors for the above outcome measures. The total annual number of RCR increased from 6,656 in 1997 to 10,128 in 2002. Ambulatory cases increased from 57% to 82% during this time period. Independent risk factors for readmission within 90 days included increasing age and increased number of comorbidities. Independent risk factors for revision RCR included increasing age, increased comorbidity, and lower surgeon volume. Hospital volume had a minimal effect on either outcome measure. The shift toward out-patient surgery mirrors the shift from open to arthroscopic rotator cuff repair. The finding that surgeon volume is a predictor of revision RCR reflects the findings in other orthopaedic procedures.

Abstract
The purpose of this study was to describe landmarks for latissimus dorsi tendon transfer in massive irreparable tears of the rotator cuff. Nine pairs of embalmed cadaveric shoulders were dissected. Crucial structures were identified, and their relationship with various bony and soft-tissue reference points was documented. Identification of the dense fibrous band, at the confluence of the teres major and latissimus dorsi musculotendinous unit, facilitates localization of the radial nerve, which crosses deep to this landmark. The axillary nerve can be seen to exit the quadrangular space 27 mm medial to the latissimus dorsi insertion into the proximal humerus, whereas the thoracodorsal neurovascular pedicle inserts into the latissimus dorsi 110 mm from the humeral tendon's humeral attachment. Harvest of the latissimus dorsi tendon can be safely accomplished by identifying the dense fibrous band and releasing the tendon within 2 cm of its humeral attachment.

Abstract
BACKGROUND A questionnaire for patient self-assessment of shoulder function was designed. It was based on the internationally accepted Rowe score. METHOD Explanations and photographs were added to the various parameters to make them easier to understand for the patients. A total of 95 patients completed the assessment form. The validity was tested by a correlation analysis comparing the questionnaire with the original score. RESULTS The questionnaire demonstrated a reproducible and significant (p<0.001), very high correlation (r>0.9) in the overall results and a moderate to very high correlation within single parameters (r>0.68). CONCLUSION Based on these results, it can be concluded that a valid and reproducible assessment of the original score is possible with the new questionnaire. Self-evaluation allows reliable assessment which is not dependent on the examiners or location, resulting in a higher number of patients reachable for follow-up studies.

Abstract
The risk of glenoid component failure has led us to explore nonprosthetic glenoid arthroplasty coupled with humeral hemiarthroplasty, the "ream and run" (R&R) procedure, for the management of glenohumeral arthritis in active patients. We hypothesized that patients having a R&R procedure would have outcomes comparable with those of similar patients having a total shoulder arthroplasty (TSA). A case-matched control study compared 35 consecutive patients (32 men, 3 women) with an average age of 56 years, after R&R with matched controls having TSA. The respective Simple Shoulder Test (SST) scores for the R&R and TSA groups were 4.5 and 4.0 before surgery, 7.8 and 9.6 at 12 months, 8.3 and 10.2 at 18 months, 8.9 and 9.4 at 24 months, 9.4 and 9.6 at 30 months, and 9.5 and 10.0 at 36 months. The "ream and run" procedure can offer similar functional recovery to patients with total shoulder arthroplasty, although the time to recovery may be longer.

Abstract
A consecutive series of patients (n = 149) completed 4 self-reporting scales (Disabilities of the Arm, Shoulder and Hand [DASH] questionnaire; Simple Shoulder Test [SST]; Western Ontario Rotator Cuff [WORC] questionnaire; and Short Form 36 [SF-36]) during the week before rotator cuff repair and 6 months after surgery. Patients were divided into 3 groups: those who had a positive response on all 3 upper extremity scales (n = 86) were classified as positive responders, those who did not demonstrate a consistent direction of response across scales were labeled as equivocal responders (n = 36), and those with a negative response across all 3 scales were labeled as negative responders (n = 15). Standardized response means (SRMs) were calculated. The WORC questionnaire (SRM, 2.0) and SST (SRM, 1.8) were most responsive to detecting improvement, followed by the DASH questionnaire (SRM, 1.6). The SF-36 was least responsive, with the largest effect on health being noted in the SF-36 subscale on bodily pain (SRM, 1.1). Pearson correlations indicated moderate associations between change scores across upper limb scales (r = 0.68-0.72) and lower associations with SF-36 physical summary scores (r = 0.40-0.50). Mental health scores were lower at baseline and changed more negatively in patients who did not have a positive response to surgery. No best scale can be identified at this time.

Abstract
The purpose of this study is to define the self-assessed deficits in function and general health perceived by a large cohort of patients with common shoulder diagnoses. For a 10-year period, all new shoulder patients presenting to the senior author were characterized by diagnosis, age, gender, and self-assessed shoulder function and general health status. This report concerns the 2674 patients having 1 of the 16 most prevalent diagnoses. The deficits in shoulder function and health status were correlated with diagnosis, age, and gender, as well as with each other. Patient self-assessment provided a standardized method for collecting data on shoulder function and health status. These assessments revealed substantial deficits; for example, 81% of patients were unable to sleep on the affected side, and 71% were unable to wash the back of the opposite shoulder. The magnitude of these deficits correlated significantly with gender and diagnosis but not with age.

Abstract
PURPOSE The purpose of this study was to evaluate at the mRNA level a subset of extracellular matrix molecules relevant during healing and remodeling of rotator cuff tears. TYPE OF STUDY Controlled laboratory study. METHODS Bursal and rotator cuff tissue from the margin of the rotator cuff tear were harvested from 10 patients (mean age, 57.5 +/- 7.3 years) undergoing surgical repair of full-thickness rotator cuff tears. There were six male and four female patients with a mean duration of symptoms of 14.6 months (range, 2 to 60 months). The mean tear size was 4.4 cm. In addition, tissue was obtained from 6 cadaveric specimens with no gross evidence of rotator cuff tearing. Reverse transcription polymerase chain reaction (RT-PCR) was performed for type I, II, and III collagen, biglycan, decorin, and aggrecan, and normalized to the housekeeping gene GAPDH. RESULTS RT-PCR showed that both the bursa and rotator cuff margin had increased mRNA levels for type I and type III collagen in patients with full-thickness rotator cuff tears when compared with normal cadaveric controls. In addition, there was a significant decrease in decorin mRNA levels and an increase in aggrecan mRNA levels in the rotator cuff margin of torn rotator cuff tendons when compared with normal cadaveric controls. CONCLUSIONS These results suggest that both the bursa and rotator cuff margin of patients with rotator cuff tears are actively remodeling after injury and that both tissues may potentially contribute to the healing process following repair. CLINICAL RELEVANCE These findings may help clinicians determine what aspects of the repair process can be manipulated to affect optimal ruptured tendon repair.

Abstract
Rotator cuff disease is a complex condition. It includes a variety of pathologies, ranging from tendinosis to complete tear. The cause seems to be multifactorial and is most likely a combination of major trauma, microtrauma from daily wear and tear, and age related degeneration. When establishing a program for the patient with rotator cuff dysfunction, the rehabilitation specialist should consider biomechanical factors, the patient's functional goals, and issues beyond the shoulder that may affect the course of the disease.

Abstract
BACKGROUND The relationship between the characteristics of the shoulder that can be determined before humeral hemiarthroplasty and the functional improvement after surgery is not known. The goal of this study was to test the hypothesis that the functional outcome of this procedure correlated significantly with factors that are identifiable preoperatively. METHODS The study group included seventy-one shoulders in sixty-eight patients undergoing hemiarthroplasty, performed by the same surgeon, for diagnoses other than acute fracture. The mean age of the patients was sixty-one years (range, thirty to eighty-three years). The results were characterized in terms of the change in self-assessed shoulder function and general health status at an average of forty-nine months (range, twenty-four to 142 months) after surgery. RESULTS The preoperative absence of erosion of the glenoid was associated with greater improvement in shoulder function and level of comfort after hemiarthroplasty (p < 0.001). Shoulders that had not had previous surgery had greater functional improvement than did those that had previous surgery (p = 0.012). Shoulders with an intact rotator cuff showed significantly (p < 0.5) greater improvement in the ability to lift weight above shoulder level after hemiarthroplasty (p <0.5). With regard to diagnoses, shoulders with rheumatoid arthritis, capsulorrhaphy arthropathy, and cuff tear arthropathy had the least functional improvement, whereas those with osteonecrosis (p = 0.0004) and with primary (p = 0.02) and secondary degenerative joint disease (p = 0.03) had the greatest improvement. Patient age and gender did not significantly affect the outcome. CONCLUSIONS These results suggest that the functional improvement following humeral hemiarthroplasty is related to factors that are identifiable before surgery. These data may be of benefit in preoperative discussions with patients who have a shoulder disorder and are considering treatment with hemiarthroplasty.

Abstract
BACKGROUND Rotator cuff tears are a cause of pain and disability in the shoulder. The molecular changes associated with rotator cuff tearing are unclear. A subset of matrix metalloproteinases and tissue inhibitors of metalloproteinase, which are involved in extracellular matrix remodeling and degradation, were evaluated. HYPOTHESIS There would be an increase in the mRNA level of specific matrix metalloproteinase and a decrease in the mRNA level of specific tissue inhibitors of metalloproteinase in rotator cuff tendon tissue obtained from patients with rotator cuff tears. STUDY DESIGN Controlled laboratory study. METHODS Tissue was obtained from 10 patients undergoing rotator cuff repair for full-thickness rotator cuff tears. Also, tissue was obtained from cadaveric specimens with no gross evidence of rotator cuff tearing. Reverse transcription polymerase chain reaction was performed for the collagenases (MMP-1, MMP-8, MMP-13), the stromelysins (MMP-3, MMP-10, MMP-11), and the tissue inhibitors of metalloproteinase (TIMP-1, TIMP-2, TIMP-3, TIMP-4). Western blotting was performed to confirm the mRNA changes demonstrated in collagenase-3 (MMP-13). RESULTS There was a significant increase in collagenase-3 (MMP-13) mRNA levels, a decrease in stromelysin-1 (MMP-3) mRNA levels, and a decrease in tissue inhibitor of metalloproteinase-2, -3, and -4 mRNA levels. Western blotting demonstrated an increase in the active form of collagenase-3 (MMP-13) in rotator cuff tendon tears. CONCLUSIONS The mRNA levels of specific matrix metalloproteinases and tissue inhibitors of metalloproteinase are altered in torn rotator cuff tendons. CLINICAL RELEVANCE With the known action of the matrix metalloproteinases and tissue inhibitors of metalloproteinase in extra-cellular matrix remodeling, these findings suggest that their roles in remodeling of rotator cuff tears should be further investigated.

Abstract
BACKGROUND During shoulder replacement surgery, the normal height of the proximal part of the humerus relative to the tuberosities frequently is not restored because of differences in prosthetic geometry or problems with surgical technique. The purpose of the present study was to determine the effect of humeral prosthesis height on range of motion and on the moment arms of the rotator cuff muscles during glenohumeral abduction. METHODS Tendon excursions and abduction angles were recorded simultaneously in six cadaveric specimens during passive glenohumeral abduction in the scapular plane. Moment arms were calculated for each muscle by computing the slope of the tendon excursion-versus-glenohumeral abduction angle relationship. The experiments were carried out with the intact joint and after replacement of the humeral head with a prosthesis that was inserted in an anatomically correct position as well as 5 and 10 mm too high. RESULTS Insertion of the prosthesis in positions that were 5 and 10 mm too high resulted in significant and marked reductions of the maximum abduction angle of 10 degrees (range, 5 degrees to 18 degrees ) and 16 degrees (range, 12 degrees to 20 degrees ), respectively. In addition, the moment arms of the infraspinatus and subscapularis decreased by 4 to 10 mm. This corresponded to a 20% to 50% decrease of the abduction moment arms of the infraspinatus and an approximately 50% to 100% decrease of the abduction moment arms of the subscapularis, depending on the abduction angle and the part of the muscle being considered. CONCLUSIONS If a humeral head prosthesis is placed too high relative to the tuberosities, shoulder function is impaired by two potential mechanisms: (1) the inferior capsule becomes tight at lower abduction angles and limits abduction, and (2) the center of rotation is displaced upward in relation to the line of action of the rotator cuff muscles, resulting in smaller moment arms and decreased abduction moments of the respective muscles. CLINICAL RELEVANCE In patients managed with shoulder replacement surgery, limitation of range of motion, loss of abduction strength, and overload with long-term failure of the supraspinatus tendon are potential consequences of positioning the humeral head of the prosthesis proximal to the anatomic position.

Abstract
Failure of shoulder arthroplasty is often defined as a complication or the need for revision, but it may also be viewed as a result that does not meet the expectations of the patient. To enhance our understanding of failed shoulder arthroplasties, we identified the characteristics common to a series of 139 consecutive patients who came to our shoulder consultation service because of dissatisfaction with the result of their shoulder arthroplasty. Primary osteoarthritis (28%) and proximal humeral fractures (26%) were the most common indications for the initial arthroplasty. Seventy-three shoulders (fifty-two percent) had at least one surgery before arthroplasty was performed. Seventy-four percent of the shoulders were stiff, 35% were unstable, and in the total shoulders, 59% of the glenoids were loose. Components were substantially malpositioned in 23%. Forty-two percent of shoulders with a failed hemiarthroplasty had substantial glenoid erosion, and 43% of shoulders that had undergone a hemiarthroplasty for fracture had nonunion of the tuberosities. Patients demonstrated impaired shoulder function; on average, they could perform only 2 of 12 shoulder functions. The rate of revision underestimated the rate of failure, as 23% of arthroplasties did not undergo revision. The challenge of achieving patient satisfaction after arthroplasty may be greater than previously recognized. Many of these unsatisfactory shoulder arthroplasties did not meet the criteria for failure used in previously published series. These observations suggest that greater attention to achieving proper component position, postoperative motion, and in fracture cases, fixation of the tuberosities may lead to increased patient satisfaction after shoulder arthroplasty.

Abstract
BACKGROUND Both shoulder surgeons and patients who are considering total shoulder arthroplasty are interested in the anticipated improvement in shoulder comfort and function after the procedure. The purpose of the present study was to characterize shoulder-specific functional gains in relation to preoperative shoulder function and to present this information in a way that can be easily communicated to patients who are considering this surgery. METHODS We analyzed the preoperative and follow-up shoulder function in patients managed with total shoulder arthroplasty for the treatment of primary glenohumeral osteoarthritis. Functional self-assessments were available for 102 (80%) of 128 shoulders after thirty to sixty months of follow-up. Outcome was assessed with respect to the change in the number of shoulder functions that were performable, the change in shoulder function as a percentage of the preoperative functional deficit, and the change in the ability to perform specific shoulder functions. RESULTS The average number of shoulder functions that were performable improved from four of twelve preoperatively to nine of twelve postoperatively (p < 0.01). Function improved in ninety-six shoulders (94%). The number of functions that were performable at the time of follow-up was positively associated with preoperative shoulder function (p < 0.05): the better the preoperative function, the better the follow-up function. The improvement in function was greatest for shoulders with less preoperative function (p < 0.01). On the average, patients regained approximately two-thirds of the functions that had been absent preoperatively. Significant improvement was noted in eleven of the twelve shoulder functions that were examined (p < 0.01). The chance of regaining a function that had been absent before surgery was 73%, whereas the chance of losing a function that had been present before surgery was 6%. Older men tended to have greater functional improvement than younger men. CONCLUSION Total shoulder arthroplasty for the treatment of primary glenohumeral osteoarthritis significantly improves shoulder function. Postoperative function is related to preoperative function. The improvement that was observed in this clinical series can be conveyed to patients most simply by stating that, after surgery, shoulders typically regained approximately two-thirds of the functions that had been absent preoperatively.

Abstract
The repair of full thickness rotator cuff tears traditionally has included acromioplasty and coracoacromial ligament section. Acromioplasty can be complicated by deltoid detachment, compromise of the deltoid lever arm, anterosuperior instability, and adhesions of the rotator cuff tendons under the bleeding cancellous bone of the osteotomized acromion. This report concerns the improvement in shoulder function at a minimum of 2 years after 27 full thickness rotator cuff repairs were done without deltoid detachment, acromioplasty, or section of the coracoacromial ligament. The mean number of Simple Shoulder Test functions that the patients could do increased from six of 12 before surgery to 10 of 12 at an average followup of 4 years after surgery. Eight of 12 individual Simple Shoulder Test functions were significantly improved after the procedure. There also was a significant improvement in the Short Form-36 comfort, physical role function, and mental health scores. When done without acromioplasty, cuff repair avoids the possibility of deltoid detachment, altered deltoid mechanics, anterosuperior instability, and tendon scarring to the cancellous undersurface of the acromion.

Abstract
A total of 191 patients from 29 orthopedic practices are analyzed in this report. All had full-thickness tears documented by imaging tests and/or surgical observation; 190 had tears of the supraspinatus, 54 had tears of the infraspinatus, and 13 had tears of the subscapularis. The greatest functional deficits were in the ability to place 8 pounds on a shelf at the level of the head (93% unable), the ability to throw overhand (93% unable), and the ability to sleep on the affected side (86% unable). The SF-36 physical role function and comfort scores were 27% and 48%, respectively, of those of age- and sex-matched controls. Of the variables suggested by a review of the literature, only female sex, involvement of the infraspinatus in the cuff tear, and workers' compensation claims were significantly correlated with lower shoulder function in this series of patients.
