RESUMEN
PURPOSE: To investigate the efficacy of arthroscopic subacromial balloon placement for massive rotator cuff tear (MRCT), assessing patient satisfaction, outcomes, shoulder functionality, pain scores, and revision-free survivorship up to 8 years after the initial surgery. METHODS: In this retrospective study with prospective data collection, patients with MRCTs undergoing balloon placement from 2014 to 2017 were prospectively enrolled. Their outcomes were analyzed retrospectively over a minimum 5-year follow-up. Demographics, patient satisfaction, reoperations, and complications were documented. Minimal clinically important differences were calculated for 12-Item Short Form Health Survey scores and Constant-Murley score subscores. Pre- and postsurgery measures statistically compared for anatomic and functional evaluations. RESULTS: In a study with 61 participants initially, 10 were lost to follow-up over 3 years. Of the remaining 51, 9 were lost at the latest follow-up. The cohort (42 participants, mean age 63.17 ± 7.66 years) was monitored for 83.98 ± 9.50 months. Seven participants required revisions within 2 years, resulting in an 83.33% revision-free survival rate. Significant improvements were observed from preoperative to latest follow-up: acromiohumeral interval decreased (7.83 to 6.56, P = .004), critical shoulder angle increased (36.10 to 38.24, P = .001), osteoarthritis grade increased (1.45 to 2.81, P = .001), 12-Item Short Form Health Survey physical score improved (27.40 to 37.69, P = .001), and Constant-Murley total scores increased (26.50 to 68.69, P = .001). Minimal clinically important difference for total Constant-Murley scores was 11.78 points. Among those without revisions, satisfaction rates were 11.43% excellent, 57.14% satisfied, and 31.43% dissatisfied. CONCLUSIONS: Employing a balloon spacer for MRCTs yielded moderate satisfaction at the 5-year follow-up, with stable revision rates within the first 2 years. Notably, low revision surgery rates, high revision-free survival, and significant shoulder functionality improvements were observed at a minimum 5-year follow-up with arthroscopic subacromial balloon placement in conjunction with biceps tenotomy and subacromial bursectomy for MRCT. LEVEL OF EVIDENCE: Level IV, retrospective study.
RESUMEN
Total ankle arthroplasty is increasingly being used for the treatment of ankle osteoarthritis when compared to arthrodesis. However, there has been limited investigation into disparities in utilization of these comparable procedures. This study examined racial/ethnic, socioeconomic, and payer status disparities in the likelihood of undergoing total ankle arthroplasty compared with ankle arthrodesis. Patients with a diagnosis of ankle osteoarthritis from 2006 through 2019 were identified in the National Inpatient Sample, then subclassified as undergoing total ankle arthroplasty or arthrodesis. Multivariable logistic regression models, adjusted for hospital location, primary or secondary osteoarthritis diagnosis, and patient characteristics (age, sex, infection, and Elixhauser comorbidities), were used to examine the effect of race/ethnicity, socioeconomic status, and payer status on the likelihood of undergoing total ankle arthroplasty versus arthrodesis. Black and Asian patients were 34% and 41% less likely than White patients to undergo total ankle arthroplasty rather than arthrodesis (p < .001). Patients in income quartiles 3 and 4 were 22% and 32% more likely, respectively, than patients in quartile 1 to undergo total ankle arthroplasty rather than arthrodesis (p = .001 and p = .01, respectively). In patients <65 years of age, privately insured and Medicare patients were 84% and 37% more likely, respectively, than Medicaid patients to undergo total ankle arthroplasty rather than arthrodesis (p < .001). Racial/ethnic, socioeconomic, and payer status disparities exist in the likelihood of undergoing total ankle arthroplasty versus arthrodesis for ankle osteoarthritis. More work is needed to establish drivers of these disparities and identify targets for intervention, including improvements in parity in relative procedure utilization.
RESUMEN
BACKGROUND: In 2009, the American Academy of Orthopaedic Surgeons released a consensus recommending venous thromboembolism (VTE) prophylaxis after total shoulder arthroplasty (TSA). The purpose of this study was to examine the (1) change in incidence of 90-day VTE, deep vein thrombosis (DVT), and pulmonary embolism; (2) change in utilization of chemoprophylaxis; and (3) change in the economic burden associated with VTE after TSA from 2010 to 2019. METHODS: Using the PearlDiver database, national data from 2010 to 2019 were used to identify patients who underwent primary TSA for osteoarthritis and/or rotator cuff arthropathy. Exclusions entailed liver pathology, coagulopathy, or those on prior prescribed blood thinners before TSA. Multivariable regression was used controlling for age and Charlson Comorbidity Index for all years with 2010 as the reference year. RESULTS: From 2010 to 2019, there was a reduction in VTE rates from 0.89% in 2010 to 0.78% in 2019. Regarding implant type, there was no notable change in incidence of VTE, DVT, and pulmonary embolism within 90 days after anatomic TSA. Notable reductions were observed in both VTE and DVT after reverse TSA from 2010 to 2019. Prescribed chemical VTE prophylaxis utilization after TSA markedly increased from 4.41% in 2010 to 11.70% utilization in 2019. The utilization of aspirin markedly increased from 17.27% in 2010 to 65.17% in 2019. Among anticoagulants, the utilization of direct factor Xa inhibitors increased from 0.0% utilization in 2010 to 66.09% utilization in 2019. The added reimbursements associated with VTE after TSA markedly decreased from $14,122 in 2010 to $4,348 in 2019. CONCLUSION: The incidence and economic burden associated with VTE after TSA have markedly declined following the 2010 American Academy of Orthopaedic Surgeons clinical practice guidelines. This reduction can be attributed to both an increase in VTE prevention through increased utilization of prescribed chemoprophylaxis and improvement in VTE treatment strategies. LEVEL OF EVIDENCE: Therapeutic, III.

The purpose of this study was to determine whether there has been any change in osteoporosis treatment following primary fragility fractures and what agents were being given. The study found an overall low utilization rate with no difference in treatment utilization from 2011 to 2019. PURPOSE: The aim of this study is to describe trends in the utilization of anti-osteoporotic medication after fragility fracture, including changes in the specific types of medications prescribed. METHODS: Patients older than 65 with fragility fractures sustained from 2011 to 2019 were identified in the PearlDiver Patient Records Database. Osteoporosis treatment rate was defined as the rate at which patients were prescribed any of the fourteen most used anti-osteoporotic medications within 1 year of fragility fracture. Fragility fractures were subcategorized by type. Treatment of fragility fractures was further stratified by patient demographics (age and gender) and medication type. RESULTS: This study showed an overall osteoporosis treatment rate of 8.01%, with treatment rates of 6.87% following hip fractures, 6.71% following upper extremity fractures, and 14.38% following vertebral compression fractures (VCF). From 2011 to 2018, there was no change in the overall fragility fracture treatment rate (p = 0.32). Of the three fracture categories analyzed, only the treatment rate for VCFs increased (p = 0.048). Osteoporosis treatment in patients with VCF increased among patients 65-74 years old (p < 0.05) and male patients (p = 0.013). Treatment in patients with upper extremity fractures increased among patients 70-74 years old (p = 0.038). Bisphosphonates were the most frequently prescribed class of medications. Bisphosphonates and denosumab increased in utilization (p = 0.049 and p < 0.001 respectively) while calcitonin utilization decreased (p < 0.001). CONCLUSION: Besides the overall low utilization rate of osteoporosis treatment in patients following fragility fractures, there has been no change in the treatment utilization rate within the past decade. More resources and interventions need to be enforced for all providers managing these patients if we are ever to address the osteoporosis epidemic.

Selection of appropriate candidates for simultaneous bilateral total knee arthroplasty (si-BTKA) is crucial for minimizing postoperative complications. The aim of this study was to develop a scoring system for identifying patients who may be appropriate for si-BTKA. Patients who underwent si-BTKA were identified in the National Surgical Quality Improvement Program database. Patients who experienced a major 30-day complication were identified as high-risk patients for si-BTKA who potentially would have benefitted from staged bilateral total knee arthroplasty. Major complications included deep wound infection, pneumonia, renal insufficiency or failure, cerebrovascular accident, cardiac arrest, myocardial infarction, pulmonary embolism, sepsis, or death. The predictive model was trained using randomly split 70% of the dataset and validated on the remaining 30%. The scoring system was compared against the American Society of Anesthesiologists (ASA) score, the Charlson Comorbidity Index (CCI), and legacy risk-stratification measures, using area under the curve (AUC) statistic. Total 4,630 patients undergoing si-BTKA were included in our cohort. In our model, patients are assigned points based on the following risk factors: +1 for age ≥ 75, +2 for age ≥ 82, +1 for body mass index (BMI) ≥ 34, +2 for BMI ≥ 42, +1 for hypertension requiring medication, +1 for pulmonary disease (chronic obstructive pulmonary disease or dyspnea), and +3 for end-stage renal disease. The scoring system exhibited an AUC of 0.816, which was significantly higher than the AUC of ASA (0.545; p < 0.001) and CCI (0.599; p < 0.001). The BTK Safety Score developed and validated in our study can be used by surgeons and perioperative teams to risk stratify patients undergoing si-BTKA. Future work is needed to assess this scoring system's ability to predict long-term functional outcomes.

Background: Available surveys that evaluate shoulder strength and pain often combine rotator cuff muscles making the test unable to differentiate subscapularis tears from other pathology including concomitant supraspinatus, infraspinatus tears. The purpose of this study was to validate a subscapularis-specific shoulder survey (Baltimore Orthopedic Subscapularis Score) as a viable clinical outcome assessment through analysis of psychometric properties. Methods: A 5-question survey was given to a study population of 390 patients, 136 of whom had full thickness rotator cuff tears with a minimum score of 5 (better) and a maximum score of 25 (worse). Surveys were given during the initial consultation, preoperative visit, and postoperative visit. Content validity, construct validity, test-retest reliability, responsiveness to change, internal consistency, and minimal clinically important difference using distribution and anchor-based methods were determined for our subscapularis function survey. Results: A high correlation was reported on test-retest reliability (intraclass correlation coefficient = 0.89). An acceptable internal consistency was reported for all patients surveyed (Cronbach alpha = 0.91). Floor and ceiling effects for patients with rotator cuff pathology were minimized (1% for both). Patients with an isolated subscapularis tear scored worse than supraspinatus/infraspinatus tears and exhibited similar dysfunction as patients with a supraspinatus/infraspinatus/subscapularis tear. An acceptable construct validity was reported with subscapularis-involved tears demonstrating higher scores with significance (P < .05). There was excellent responsiveness to change with a standardized response mean of 1.51 and effect size of 1.27 (large > 0.8). The minimal clinically important difference using a distribution and anchor-based method was 4.1 and 4.6, respectively. Among patients with rotator cuff tears in this population, a score of 22 or higher predicts a subscapularis tear 75% of the time, in spite of its low overall prevalence. Conclusion: The subscapularis shoulder score demonstrated acceptable psychometric performance for outcomes assessment in patients with rotator cuff disease. This survey can be used as an effective clinical tool to assess subscapularis function.
RESUMEN
AIMS: The purpose of this study is to determine differences in the rates of 90-day postoperative complications and 2- and 5-year surgical outcomes between patients with and without hereditary hemochromatosis (HH) after total joint arthroplasty (TJA). METHODS: Patients who underwent primary total hip arthroplasty (THA) or total knee arthroplasty (TKA) from 2010 to 2018 were identified in a national database (PearlDiver Technologies) using Current Procedural Terminology and International Classification of Diseases-9/10 codes. Patients with a history of HH were identified within the THA and TKA cohorts and matched with non-HH patients based on age, sex, Charlson Comorbidity Index, smoking status, and obesity (body mass index > 30). Ninety-day medical complications assessed included renal failure, arrhythmia, bleeding complications, blood transfusion, pneumonia, stroke, deep vein thrombosis, liver failure, heart failure, pulmonary embolism, sepsis, surgical site infection, wound dehiscence, readmission rate, and death. Two- and 5-year surgical complications assessed included all-cause revision, prosthetic joint infection, implant loosening, joint stiffness, and manipulation under anesthesia. All complications were analyzed using bivariate analysis and logistic regression, with significance set at P < 0.05. RESULTS: Compared with non-HH patients, patients with HH had higher rates of stiffness at 2 and 5 years after THA (all, P < 0.001), as well as higher rates of aseptic loosening at 5 years after TKA (P = 0.036). However, patients with HH undergoing THA and TKA had no notable difference in 90-day postoperative complications when compared with non-HH patients. DISCUSSION: Compared with non-HH patients, patients with HH undergoing TJA were shown to have worse 2- and 5-year surgical outcomes, without any increased risk of 90-day medical complications. These findings may be useful for surgical decision making for patients with HH undergoing TJA. CLINICAL RELEVANCE: This study addresses a paucity in the current literature concerning the complication profile in HH patients with destructive joint arthropathy undergoing joint arthroplasty surgery.

BACKGROUND: Prescription opioid misuse has become an epidemic in the United States and is a leading cause of death in Americans. Postoperative opioid prescriptions are a significant contributor to the opioid epidemic, with orthopedic surgeons being the third highest prescribers of opioid prescriptions among physicians across all specialties. Our aim was to retrospectively evaluate overall opioid consumption patterns following surgical treatment for shoulder pathology and recommend evidence-based guidelines for standardized postoperative opioid prescriptions. METHODS: We conducted a retrospective chart review of patients who underwent shoulder arthroscopy or arthroplasty from a single shoulder/elbow fellowship-trained surgeon (principal investigator). Patient and surgery characteristics were summarized for the entire sample and further stratified by surgery type. Total opioid consumption at the time of the first postoperative visit and refill patterns were compared between each surgery group. Opioid consumption was analyzed in morphine milligram equivalents (MMEs) and is reported in the equivalent number of 5-mg oxycodone tablets. RESULTS: A total of 119 patients were included in our analysis. The average age was 58 ± 13 years, and 59% of patients were male. Rotator cuff repair was the most frequent surgery (n = 52), followed by arthroplasty (n = 35) and arthroscopy (n = 28). On average, the patients in the study used 82.5 ± 233 MME units, equivalent to 11 ± 31.067 tablets of 5-mg oxycodone. Sixteen percent of patients did not use any opioids. There was no significant difference in opioid consumption or refills across surgery type. In the bivariate analysis for the entire sample, age was the only predictor that was statistically significantly associated with the amount of opioid consumption. In the multivariable model for patient demographics, significant predictors of opioid consumption were age, gender, and pain scores. In the multivariate analysis by surgery type, significant predictors of higher opioid consumption were age, gender, pain score, and surgery performed on the dominant side. CONCLUSION: On the basis of the consumption patterns observed in our patient cohort, we recommend prescribing 112.5 MME (15 tablets of 5-mg oxycodone) for arthroscopic shoulder procedures, and 75 MME (10 tablets of 5-mg oxycodone) for shoulder arthroplasties.

BACKGROUD: Many U.S. health care institutions have adopted compensation models based on work relative value units (wRVUs) to standardize payments and incentivize providers. A major determinant of payment and wRVU assignments is operative time. We sought to determine whether differences in estimated operative times between the Centers for Medicare & Medicaid Services (CMS) and the National Surgical Quality Improvement Program (NSQIP) contribute to payment and wRVU misvaluation for the most common shoulder/elbow procedures. METHODS: We collected data on wRVUs, payments, and operative times from CMS for 29 types of isolated arthroscopic and open shoulder/elbow procedures. Using regression analysis, we compared relationships between these variables, in addition to median operative times reported by NSQIP (2013-2016). We then determined the relative valuation of each procedure based on operative time. RESULTS: Seventy-nine percent of CMS operative time were longer than NSQIP time (R2 = 0.58), including, but not limited to, shoulder arthroplasty and arthroscopic shoulder surgery. The correlation between payments and operative times was stronger between CMS data (R2 = 0.61) than NSQIP data (R2 = 0.43). Similarly, the correlation between wRVUs and operative times was stronger when using CMS data (R2 = 0.87) than NSQIP data (R2 = 0.69). Nearly all arthroscopic shoulder procedures (aside from synovectomy, debridement, and decompression) were highly valued according to both datasets. Per NSQIP, compensation for revision total shoulder arthroplasty ($10.14/min; 0.26 wRVU/min) was higher than that for primary cases ($9.85, 0.23 wRVU/min) and nearly twice the CMS rate for revision cases ($5.84/min; 0.13 wRVU/min). CONCLUSIONS: CMS may overestimate operative times compared to actual operative times as recorded by NSQIP. Shorter operative times may render certain procedures more highly valued than others. Case examples show that this can potentially affect patient care and incentivize higher compensating procedures per operative time when less-involved, shorter operations have similar patient-reported outcomes.

Upper extremity surgeons perform diverse operations, including hand surgery, microsurgery, and shoulder/elbow arthroscopy and arthroplasty. Declining orthopedic reimbursement rates may encourage surgeons to adjust their case mix, favoring a shift toward procedures with higher compensation. To determine whether upper extremity surgeons and hand-fellowship trainees may be financially incentivized to perform more shoulder/elbow procedures than hand procedures in a hospital-based setting, relative value unit (RVU) compensation rates were compared for these 2 fields. Using Centers for Medicare & Medicaid Services-assigned work RVUs (wRVU) and National Surgical Quality Improvement Program operative time data, wRVU compensation rates per minute of operative time were determined for common shoulder/elbow surgeries. Overall nonweighted and weighted wRVU/min averages were calculated for hospital-based shoulder/elbow and hand surgery. A total of 27 shoulder/elbow procedures and 53 hand surgery procedures were analyzed. Nonweighted comparison showed shoulder/elbow surgery had a higher wRVU/min (0.19±0.03 vs 0.14±0.05, P<.0001) vs hand surgery. When weighted by procedure frequency, shoulder/elbow surgery also had higher wRVU/min (0.19±0.02 vs 0.15±0.05, P<.0001). Fourteen of the 27 shoulder/elbow procedures were compensated either the same wRVU/min or more than all hand procedures except for epicondyle debridement and flexor tendon bursectomy. Almost half of commonly performed shoulder/elbow procedures were compensated at greater rates than most hand procedures in a hospital-based setting. This disproportionate compensation may affect upper extremity surgeons' case mix and motivate providers and hand-fellowship trainees to seek additional training in shoulder arthroplasty and arthroscopy to supplement their practice.

Background: Many US health care institutions have adopted compensation models based on work relative value units (wRVUs) to standardize payments and incentivize providers. Among other factors, a major determinant of payment and wRVU assignments is operative time. Our objective was to determine whether differences in estimated operative times between the Centers for Medicare & Medicaid Services (CMS) and the National Surgical Quality Improvement Program (NSQIP) contribute to payment and wRVU misvaluation for the most common hospital-based hand and upper extremity procedures. Methods: Data on wRVUs, surgeon payment, and estimated operative times were collected from CMS for 53 procedures. We used regression models to compare relationships between these variables, in addition to actual median operative times as reported in the NSQIP database, from 2011 to 2016. We then determined the relative valuation of each procedure based on operative time. Results: There was a wide discrepancy between CMS and NSQIP operative times (R2=0.49), with 60% of CMS times being longer than NSQIP times. Payment correlated more strongly with CMS operative times (R2=0.55) than with NSQIP operative times (R2=0.24). Similarly, wRVUs more strongly correlated with CMS operative times (R2=0.84) than with NSQIP operative times (R2=0.51). In general, for trauma-related procedures, any distal radius open reduction internal fixation (ORIF) had the highest valuation while any ORIF proximal to the distal radius had lower valuation in analysis of both databases. While 61% of trauma procedures were highly valued, 70% of elective procedures had a low valuation, including nearly all elective tendon procedures. Notable compensation differences were found between trapeziectomy versus ligament reconstruction and tendon interposition, epicondyle debridement with tendon repair versus denervation, proximal row carpectomy versus four corner fusion, and distal radius open versus percutaneous fixation. Conclusions: CMS may misvalue payment and wRVU rates of hospital-based hand procedures due to inaccurate operative time estimates. By identifying which procedures are misvalued in terms of payment and wRVU per operative time, providers and payors may be able to address these imbalances and maximize appropriate care delivery incentives.Level of Evidence: III.

BACKGROUND: There is no consensus on the treatment of irreparable massive rotator cuff tears. The goal of this systematic review and meta-analysis was to (1) compare patient-reported outcome scores, (2) define failure and reoperation rates, and (3) quantify the magnitude of patient response across treatment strategies. METHODS: The MEDLINE, Embase, CENTRAL (Cochrane Central Register of Controlled Trials), and Scopus databases were searched for studies including physical therapy and operative treatment of massive rotator cuff tears. The criteria of the Methodological Index for Non-randomized Studies were used to assess study quality. Primary outcome measures were patient-reported outcome scores as well as failure, complication, and reoperation rates. To quantify patient response to treatment, we compared changes in the Constant-Murley score and American Shoulder and Elbow Surgeons (ASES) score with previously reported minimal clinically important difference (MCID) thresholds. RESULTS: No level I or II studies that met the inclusion and exclusion criteria were found. Physical therapy was associated with a 30% failure rate among the included patients, and another 30% went on to undergo surgery. Partial repair was associated with a 45% retear rate and 10% reoperation rate. Only graft interposition was associated with a weighted average change that exceeded the MCID for both the Constant-Murley score and ASES score. Latissimus tendon transfer techniques using humeral bone tunnel fixation were associated with a 77% failure rate. Superior capsular reconstruction with fascia lata autograft was associated with a weighted average change that exceeded the MCID for the ASES score. Reverse arthroplasty was associated with a 10% prosthesis failure rate and 8% reoperation rate. CONCLUSION: There is a lack of high-quality comparative studies to guide treatment recommendations. Compared with surgery, physical therapy is associated with less improvement in perceived functional outcomes and a higher clinical failure rate.

BACKGROUND: There is a high demand for shoulder/elbow experience among hand-fellowship trainees due to the perception that this exposure will improve their professional "marketability" in a subspecialty they perceive as having higher compensation. METHODS: Using Medicare data, we investigated the most common surgeries from these fields and determined which have the highest compensation [work relative value unit (wRVU), payment, charge, and reimbursement (payment-to-charge percentage] rates per operative time. We then determined whether the overall non-weighted and weighted (by surgical frequency/volume) compensation rates of shoulder/elbow surgery are greater than that of hand surgery. RESULTS: Among 30 shoulder/elbow procedures, arthroplasty and arthroscopic rotator cuff repair had the highest payment and wRVU assignments. Among 83 hand procedures, upper-extremity flaps, carpal stabilization, distal radius open reduction internal fixation (ORIF), both-bone ORIF, and interposition arthroplasty had the greatest wRVU assignments with correspondingly high payments. A non-weighted comparison of the two subspecialties showed that hand surgery has a higher mean payment/min ($10.46±3.22 vs. $7.52±2.89), charge/min ($51.02±17.11 vs. $41.96±11.32), and reimbursement (21±4.7% vs. 18±5.1%) compared with shoulder/elbow surgery (all, P<0.01). Non-weighted mean wRVUs/min were similar (0.12±0.03 vs. 0.13±0.03, P = 0.12). When weighted by procedure frequency, hand surgery had greater wRVUs/min (0.15±0.036 vs. 0.13±0.032), payments/min ($14.17±4.50 vs. $6.97±2.26), charges/min ($75.68±30.47 vs. $42.61±7.83), and reimbursement (20±5.0% vs. 17±6.0%) (all, P<0.01). CONCLUSION: According to Medicare compensation, and when weighted by procedure frequency, hand procedures are associated with greater overall mean wRVUs/min, payments/min, charges/min, and reimbursement compared with shoulder and elbow procedures. Hand-surgery fellowship applicants should be aware that subspecialty compensation is complex in nature but should seek shoulder/elbow elective experience to acquire an additional surgical skill-set as opposed to primarily monetary reason.
RESUMEN
BACKGROUND: The incidence of scapular winging is unclear, but it may be more common than previously thought. It can be difficult to diagnose because the presenting complaint and physical examination may direct the practitioner toward more common shoulder and neck conditions. Ongoing scapular dysfunction may result in inappropriate or failed surgery. Our goals were to (1) describe the common misdiagnoses (instability, labral abnormality, impingement, and cervical spine disease), the clinical scenarios and examination findings leading to diagnostic difficulty, the definitive treatment options available, and the clinical outcomes and complications; and (2) review the important aspects of the patient history, physical examination of the scapula, and associated studies necessary to make the correct diagnosis of scapular winging. METHODS: We reviewed the literature relative to, and our own experience with, the treatment of scapular winging and identified a series of patients with this condition who were initially misdiagnosed with other shoulder or spine abnormalities. In our literature search, only nine clinical studies reported on a series of patients with scapular winging that was initially misdiagnosed or had a delay in diagnosis (n = 53 patients). We examined these cases for presenting or preexisting diagnoses and for surgical procedures that had been performed before the diagnosis of scapular winging. RESULTS: For patients ultimately diagnosed with scapular winging, initial presentations and diagnoses included rotator cuff disorders (20%), glenohumeral instability (8%), peripheral nerve disorders (6%), cervical spine disease (6%), acromioclavicular disorders (6%), thoracic outlet syndrome (4%), and unknown or unspecified (41%). The most common surgical procedures performed before definitive scapular winging treatment were rotator cuff (22%), instability (22%), nerve (14%), acromioclavicular (12%), cervical spine (5%), and thoracic outlet (4%) procedures. CONCLUSIONS: Clinically, scapular winging often mimics more common shoulder abnormalities and can result in unnecessary or unsuccessful surgical procedures. Diagnosis can be readily achieved with simple physical examination and specific provocative maneuvers in conjunction with electromyography and nerve conduction studies. Prompt diagnosis and recognition can avoid substantial shoulder dysfunction.

BACKGROUND: Over the past twenty-five years, peripheral nerve blocks have become increasingly common for the management of perioperative pain of the upper extremity. Several factors have led to increasing acceptance and use of these peripheral nerve blocks, including a greater awareness and measurement of patient pain and a greater emphasis on decreasing the duration of hospital stays and associated costs. METHODS: We present a review of peripheral nerve blocks for procedures involving the upper extremity, including indications, contraindications, anatomy and technique, expected clinical outcomes and the associated levels of evidence, cost-effectiveness, and complications. We reviewed the scientific literature for studies on the effectiveness of peripheral nerve blocks for orthopaedic procedures involving the upper extremity. Particular attention was directed at the most commonly used nerve blocks, the levels of evidence supporting their use, and emerging technologies such as ultrasonographic guidance. RESULTS: Peripheral nerve blocks for upper-extremity procedures improve postoperative pain control and patient satisfaction, can be administered safely, and have a low complication rate. They are also associated with enhanced participation in postoperative rehabilitation, decreased hospital stays, and decreased costs. There are increasingly higher levels of evidence in the literature to support the use of peripheral nerve blocks in a wide variety of orthopaedic procedures ranging from the shoulder to the hand. CONCLUSIONS: The use of peripheral nerve blocks in upper-extremity surgery is common. To actively participate with the patient and anesthesiologist to ensure the best possible outcomes, the orthopaedic surgeon must be well informed regarding the benefits and limitations of this modality.

BACKGROUND: The Latarjet coracoid process transfer procedure is an established, reliable treatment for glenoid deficiency associated with recurrent anterior shoulder instability, but changes in neurovascular anatomy resulting from the procedure are a concern. The purpose of our cadaveric study was to identify changes in the neurovascular anatomy after a Latarjet procedure. MATERIALS AND METHODS: We obtained 4 paired, fresh-frozen cadaveric forequarters (8 shoulders) from the Maryland State Anatomy Board. In each shoulder, we preoperatively measured the distances from the midanterior glenoid rim to the musculocutaneous nerve, axillary nerve, and axillary artery in 2 directions (lateral to medial and superior to inferior) and with the arm in 2 positions (0° abduction/neutral rotation; 30° abduction/30° external rotation), for a total of 12 measurements. We then created a standardized bony defect in the anterior-inferior glenoid, reconstructed it with the Latarjet procedure, and repeated the same measurements. Two examiners independently took each measurement twice. Inter-rater reliability was adequate, allowing pre-Latarjet measurements to be combined, averaged, and compared with combined and averaged post-Latarjet measurements by using paired Student t tests (significance, P ≤ .05). RESULTS: We found (1) significant differences in the location of the musculocutaneous nerve in the superior-to-inferior direction for both arm positions, (2) notably lax and consistently overlapping musculocutaneous and axillary nerves, and (3) an unchanged axillary artery location. CONCLUSIONS: The Latarjet procedure resulted in consistent and clinically significant alterations in the anatomic relationships of the musculocutaneous and axillary nerves, which may make them vulnerable to injury during revision surgery.

BACKGROUND: The utilization of peripheral nerve blocks in orthopaedic surgery has paralleled the rise in the number of ambulatory surgical procedures performed. Optimization of pain control in the perioperative orthopaedic patient contributes to improved patient satisfaction, early mobilization, decreased length of hospitalization, and decreased associated hospital and patient costs. Our purpose was to provide a concise, pertinent review of the use of peripheral nerve blocks in various orthopaedic procedures of the lower extremity, with specific focus on procedural anatomy, indications, patient outcome measures, and complications. METHODS: We reviewed the literature and reference textbooks on commonly performed lower-extremity peripheral nerve block procedures in orthopaedic surgery, focusing on those most commonly used. RESULTS: The use of lower-extremity peripheral nerve blocks is a safe and effective approach to perioperative pain management. Different techniques and timing can have an important impact on patient satisfaction, and each technique has specific indications and complications. For major hip surgery, one of the most commonly used is the lumbar plexus block, which can result in early mobilization, reduced postoperative pain, and decreased opioid-associated adverse events. Associated complications include epidural spread of anesthesia, retroperitoneal hematoma formation, and postoperative falls. For arthroscopic and open knee procedures, the femoral nerve block is frequently used adjunctively. It provides improved early postoperative pain control, early mobilization with therapy, and increased patient satisfaction compared with intra-articular or intravenous opioids alone; it also provides cost savings. However, some studies have shown no significant difference in outcome measures compared with intra-articular opioids alone for arthroscopic anterior cruciate ligament reconstruction. Associated complications include nerve injury, intravascular injection, and postoperative falls. CONCLUSIONS: The use of peripheral nerve blocks in lower-extremity surgery is becoming a mainstay of perioperative pain management strategy.

BACKGROUND: No study examining pin constructs has adequately addressed pin size and its role in fracture fixation. Our goal was to review our experience with Wilkins-modified Gartland type-III pediatric supracondylar humerus fractures treated with closed reduction and percutaneous pinning to evaluate the effects of pin size within 2 different pin constructs on maintenance of reduction and on the risk of surgical complications. METHODS: We retrospectively reviewed the medical records of pediatric patients with Wilkins-modified Gartland type-III supracondylar humerus fractures that were closed reduced and percutaneously pinned at our institution from March 1999 through December 2008. We grouped those 159 patients by fracture stabilization method (lateral-entry-pin or crossed-pin constructs), by pin size ratio (ie, ratio of pin diameter to the humeral midshaft cortical thickness: small ≤0.9; large >0.9), and then by 4 combinations of pin construct and pin size ratio. For each group, we evaluated radiographs for immediate postoperative reduction (coronal and sagittal alignment), maintenance of reduction at last follow-up, and the number of surgical complications. We used the Student t test, χ² test, Mann-Whitney U test, and Wilcoxon Signed Rank test to examine for significance, which was set at P<0.05. RESULTS: Although we found no significant differences between the groups immediately after surgery, final follow-up sagittal alignment was significantly more likely to be maintained in the large pin size ratio group than in the small pin size ratio group. For 2 types of surgical complications, infection and nerve palsy, we found no statistically significant differences in these complications between the pin construct or pin size ratio groups. CONCLUSIONS: Large pin sizes improved radiographic sagittal alignment at final follow-up without an increased rate of infection or ulnar nerve palsy. LEVEL OF EVIDENCE: Level III Therapeutic Study.

STUDY DESIGN: Retrospective morphometric population study. OBJECTIVE: To characterize pedicle and spinal canal morphology of the achondroplastic lower thoracic and lumbar vertebrae and to suggest dimensions for improving pedicle screw selection and placement. SUMMARY OF BACKGROUND DATA: Although morphometric population studies exist for various races, to our knowledge, no such analysis has been made in achondroplastic patients. METHODS: With computer software, we measured pedicle parameters on the computed tomography images of 19 adult achondroplastic patients. RESULTS: Pedicle and chord lengths ranged from 9.5-12.5 mm and 29.5-36.4 mm, respectively. Transverse pedicle diameter increased from T9 (5.5 mm) to L5 (14.2 mm). Sagittal pedicle diameter declined from L1 (11.6 mm) to L5 (7.8 mm). Transverse angulation was greatest at L5 (15.7 degrees ) and smallest at T12 (1.1 degrees ). Pedicles were directed cranially at all levels, ranging from 3.8 degrees -15.6 degrees . Interpedicular distance and cross-sectional area were smallest at L4 (14.9 mm and 119 mm, respectively). Pedicle starting points diverged from T9 (13.6 mm) to L5 (19.2 mm2). CONCLUSION: Achondroplastic pedicle morphology differs markedly from those of the normal spine: chord lengths are substantially shorter, pedicles are inclined cranially, pedicle starting points diverge progressively in the lumbar spine, and pedicle shape transitions from vertically to horizontally oriented ellipsoids along the lumbar spine. Consideration of this variation could maximize the effectiveness and safety of pedicle instrumentation.
