Shoulder brace has no detrimental effect on basic spatio-temporal gait parameters and functional mobility after arthroscopic rotator cuff repair.

BACKGROUND: The risk of falls in patients undergoing orthopedic procedures is significant in terms of health and socioeconomic effects. RESEARCH QUESTION: Is there an influence of the shoulder abduction brace (SAB) on gait parameters in patients undergoing arthroscopic rotator cuff repair (ARCR)? METHODS: Thirty-five patients undergoing ARCR, who used a 15° SAB in the postoperative period, were included in a prospective study. Participants underwent gait analysis preoperatively (T0), 24 h after surgery (T1), 1 week (T2), and 4 weeks after surgery (1 week after SAB removal) (T3) by using a wearable inertial sensor (BTS G-Walk sensor). Gait Parameters (cadence, speed, right (R) and left (L) step length, gait and propulsion-R and L symmetry indices) and functional mobility (agility and balance) were assessed using the 10-meter test (10MWT) and the Timed Up and Go (TUG) test, respectively. RESULTS: There were 22 men and 13 women with a median age of 56 (IQR 48.0-61.0) years. The right upper limb was involved in 83% of cases. Regarding the 10MWT, speed was significantly higher at T0 than at T1 (p < 0.01) and significantly lower at T1 than at T3 (p < 0.05). Cadence was significantly lower at T1 than at T3 (p < 0.05). Propulsion-R was significantly higher at T3 than at T1 (p < 0.01), whereas propulsion-L was significantly lower at T1 than at T0 (p < 0.05) and significantly higher at T2 and T3 than T1 (p < 0.01 for all). No significant differences were found for R and L step lengths as well as for symmetry index (p > 0.05). Regarding TUG test, the final turning phase was significantly higher at T2 than at T3 (p < 0.01). SIGNIFICANCE: The results demonstrated that the use of the SAB affected gait speed and propulsion only 24 h after ARCR, but no effects were reported at long-term observations.

Development of a Cadaveric Shoulder Motion Simulator with Open-Loop Iterative Learning for Dynamic, Multiplanar Motion: A Preliminary Study.

Ex vivo shoulder motion simulators are commonly used to study shoulder biomechanics but are often limited to performing simple planar motions at quasi-static speeds using control architectures that do not allow muscles to be deactivated. The purpose of this study was to develop an open-loop tendon excursion controller with iterative learning and independent muscle control to simulate complex multiplanar motion at functional speeds and allow for muscle deactivation. The simulator performed abduction/adduction, faceted circumduction, and abduction/adduction (subscapularis deactivation) using a cadaveric shoulder with an implanted reverse total shoulder prosthesis. Kinematic tracking accuracy and repeatability were assessed using maximum absolute error (MAE), root mean square error (RMSE), and average standard deviation (ASD). During abduction/adduction and faceted circumduction, the RMSE did not exceed 0.3, 0.7, and 0.8 degrees for elevation, plane of elevation, and axial rotation, respectively. During abduction/adduction, the ASD did not exceed 0.2 degrees. Abduction/adduction (subscapularis deactivation) resulted in a loss of internal rotation, which could not be restored at low elevation angles. This study presents a novel control architecture, which can accurately simulate complex glenohumeral motion. This simulator will be used as a testing platform to examine the effect of shoulder pathology, treatment, and rehabilitation on joint biomechanics during functional shoulder movements.

High correlation between inner and outer glenoid circle diameters and its clinical relevance.

PURPOSE: The majority of methods for measuring glenoid bone loss in shoulder instability use the best-fit circle following the inferior glenoid rim. However, there is no precise method on how to draw this circle, particularly in case of a missing rim segment. Defining the radius is a source of substantial error. It was hypothesized that there is a relationship between the best-fit inferior circle (inner circle), defined by Sugaya, and the circle tangent to the supra- and infra-glenoid tubercles (outer circle), defined by Itoi, thus allowing a more consistent appreciation of the paleo-glenoid. METHODS: Ninety-five normal dry scapulae were examined. The specimens were digitally photographed obtaining perpendicular images of the glenoid cavity. Using HOROS® imaging software, a best-fit inferior circle (inner circle) and a second circle fitting the most inferior and superior points of the glenoid (outer circle) were drawn by two investigators. The diameters and areas of the circles were recorded. Two-way random-effects intra-class correlation coefficients (ICC) were used to measure intra- and inter-observer agreement. A Bayesian measurement-error regression model was used to determine the relationship between outer and inner circle measurements. RESULTS: The mean glenoid height was 35.1 mm and the glenoid width 25.6 mm. The mean diameter of the outer circle was 35.7 ± 4.2 mm and the mean diameter of the inner circle was 26.8 ± 3.2 mm. ICC showed excellent inter- and intra-observer agreement for both the outer circle diameter (ICC ≥ 0.95) and inner circle diameter (ICC ≥ 0.93). The two diameters demonstrated a very strong significant Pearson correlation (0.92, p < 0.001) and the regression showed excellent model fit R2 = 0.87. The areas of the two circles were also highly and significantly correlated (r = 0.94; p < 0.001). The ratio of inner circle to outer diameters was 0.74. CONCLUSION: There is a strong correlation between the inner and outer glenoid circle diameters. This study sets the base for the use the combined outer and inner circle and its ratio to better appreciate the paleo-glenoid morphology and thus obtain a more reliable bone loss estimation. Application of this method aids in a more reliable estimation bone loss with potential benefit in surgical decision-making.

Does the osteoarthritic shoulder have altered rotator cuff vectors with increasing glenoid deformity? An in silico analysis.

BACKGROUND: A transverse force couple (TFC) functional imbalance has been demonstrated in osteoarthritic shoulders by recent 3-dimensional (3D) muscle volumetric studies. Altered rotator cuff vectors may be an additional factor contributing to a muscle imbalance and the propagation of glenoid deformity. METHODS: Computed tomography images of 33 Walch type A and 60 Walch type B shoulders were evaluated. The 3D volumes of the entire subscapularis, supraspinatus, and infraspinatus-teres minor (ISP-Tm) and scapula were manually segmented. The volume masks and scapular landmarks were imported into MATLAB to create a coordinate system, enabling calculation of muscle force vectors. The direction of each muscle force vector was described in the transverse and vertical plane, calculated with respect to the glenoid. Each muscle vector was then resolved into compression and shear force across the glenoid face. The relationship between muscle force vectors, glenoid retroversion or inclination, compression/shear forces on the glenoid, and Walch type was determined using linear regression. RESULTS: In the transverse plane with all rotator cuff muscles combined, increasing retroversion was significantly associated with increasing posterior drag (P < .001). Type B glenoids had significantly more posterior drag than type A (P < .001). In the vertical plane for each individual muscle group and in combination, superior drag increases as superior inclination increases (P < .001). Analysis of individual muscle groups showed that the anterior thrust of ISP-Tm and supraspinatus switched to a posterior drag at 8° and 10° of retroversion respectively. The compression force on the glenoid face by ISP-Tm and supraspinatus did not change with increasing retroversion for type A shoulders (P = .592 and P = .715, respectively), but they did for type B shoulders (P < .001 for both). The glenoid shear force ratio in the transverse plane for the ISP-Tm and supraspinatus moved from anterior to posterior shear with increasing glenoid retroversion, crossing zero at 8° and 10° of retroversion, whereas the subscapularis exerted a posterior shear force for every retroversion angle. CONCLUSION: Increased glenoid retroversion is associated with increased posterior shear and decreased compression forces on the glenoid face, explaining some of the pathognomonic bone morphometrics that characterize the osteoarthritic shoulder. Although the subscapularis always maintains a posterior thrust, the ISP-Tm and supraspinatus together showed an inflection at 8° and 10° of retroversion, changing from an anterior thrust to a posterior drag. This finding highlights the importance that in anatomic TSA the rotator cuff functional balance might be better restored by correcting glenoid retroversion to less than 8°.

What Is the Most Reliable Method of Measuring Glenoid Bone Loss in Anterior Glenohumeral Instability? A Cadaveric Study Comparing Different Measurement Techniques for Glenoid Bone Loss.

BACKGROUND: Preoperative quantification of bone loss has a significant effect on surgical decision making and patient outcomes. Various measurement techniques for calculating glenoid bone loss have been proposed in the literature. To date, no studies have directly compared measurement techniques to determine which technique, if any, is the most reliable. PURPOSE/HYPOTHESIS: To identify the most consistent and accurate techniques for measuring glenoid bone loss in anterior glenohumeral instability. Our hypothesis was that linear measurement techniques would have lower consistency and accuracy than surface area and statistical shape model-based measurement techniques. STUDY DESIGN: Controlled laboratory study. METHODS: In 6 fresh-frozen human shoulders, 3 incremental bone defects were sequentially created resulting in a total of 18 glenoid bone defect samples. Analysis was conducted using 2D and 3D computed tomography (CT) en face images. A total of 6 observers (3 experienced and 3 with less experience) measured the bone defect of all samples with Horos imaging software using 5 common methods. The methods included 2 linear techniques (Shaha, Griffith), 2 surface techniques (Barchilon, PICO), and 1 statistical shape model formula (Giles). Intraclass correlation (ICC) using a consistency model was used to determine consistency between observers for each of the measurement methods. Paired t tests were used to calculate the accuracy of each measurement technique relative to physical measurement. RESULTS: For the more experienced observers, all methods indicated good consistency (ICC > 0.75; range, 0.75-0.88), except the Shaha method, which indicated moderate consistency (0.65 < ICC < 0.75; range, 0.65-0.74). Estimated consistency among the experienced observers was better for 2D than 3D images, although the differences were not significant (intervals contained 0). For less experienced observers, the Giles method in 2D had the highest estimated consistency (ICC, 0.88; 95% CI, 0.76-0.95), although Giles, Barchilon, Griffith, and PICO methods were not statistically different. Among less experienced observers, the 2D images using Barchilon and Giles methods had significantly higher consistency than the 3D images. Regarding accuracy, most of the methods statistically overestimated the actual physical measurements by a small amount (mean within 5%). The smallest bias was observed for the 2D Barchilon measurements, and the largest differences were observed for Giles and Griffith methods for both observer types. CONCLUSION: Glenoid bone loss calculation presents variability depending on the measurement technique, with different consistencies and accuracies. We recommend use of the Barchilon method by surgeons who frequently measure glenoid bone loss, because this method presents the best combined consistency and accuracy. However, for surgeons who measure glenoid bone loss occasionally, the most consistent method is the Giles method, although an adjustment for the overestimation bias may be required. CLINICAL RELEVANCE: The Barchilon method for measuring bone loss has the best combined consistency and accuracy for surgeons who frequently measure bone loss.

Salvage Procedures of the Shoulder: Glenohumeral Arthrodesis and Resection Arthroplasty.

BACKGROUND: With the advances of modern medicine and technology there has been an increase of indications of shoulder reconstruction techniques and shoulder arthroplasty. Consequently, the number of complications and failures have increased in parallel. Not negligible number of cases are driven to an end-stage situation where salvage procedures, such as glenohumeral arthrodesis (GHA) and shoulder resection arthroplasty (SRA), are the only remaining solution. METHODS: The current literature on glenohumeral arthrodesis and shoulder resection arthroplasty was reviewed to determine the indications, surgical technique, complications and outcomes. The electronic search was conducted using the MEDLINE and EMBASE databases and the strategies used were "glenohumeral arthrodesis", "glenohumeral fusion", "shoulder arthrodesis" and "shoulder resection arthroplasty". RESULTS: Indications for glenohumeral arthrodesis (GHA) include brachial plexus injury, tumor resections, chronic infection, failed prosthetic arthroplasty, persistent refractory instability or pseudoparalysis of the shoulder with combined irreparable rotator cuff and deltoid injuries. GHA provides good stability, pain resolution, although function is markedly compromised and relying mostly on scapulothoracic joint. The gold standard surgical technique continues to be open shoulder arthrodesis and still has a high complication rate. Shoulder resection arthroplasty (SRA) indications have evolved through the years, being nowadays a salvage procedure for recalcitrant infection of shoulder arthroplasty the main indication. Shoulder function after SRA is often severely compromised, but has a high infection rate resolution. SRA is not technically demanding and complications are rare, being the persistence of infection the most common one. DISCUSSION: Despite GHA and SRA having negative connotations, in selected patients, these procedures can diminish pain, resolve persistent infections and provide an acceptable shoulder function. Hence, they should be retained as part of the treatment algorithm for complex shoulder pathology.

Atraumatic Anterior Hip Dislocation as High Grade of Hip Instability: A Case Report.

CASE: Fifty-year-old woman who presented an atraumatic anterior hip dislocation during a local traditional dance exhibition. The dislocation occurred during a dance step in which extreme hip position in extension and external rotation was held. After urgent closed reduction under general anesthesia, the patient underwent conservative management with a follow-up of 24 months. There were no further dislocation events or sequelae, with the Hip Disability and Osteoarthritis Outcome Score-12 scale score was 100 points at the end of follow-up. CONCLUSIONS: Atraumatic hip dislocation is the highest grade and exceptional presentation of hip instability and requires immediate treatment. Conservative treatment is satisfactory, although in case of recurrence or persistent residual symptoms, other treatments are warrant.

Does the Walch type B shoulder have a transverse force couple imbalance? A volumetric analysis of segmented rotator cuff muscles in osteoarthritic shoulders.

BACKGROUND: The etiology of the Walch type B shoulder remains unclear. We hypothesized that a scapulohumeral muscle imbalance, due to a disturbed transverse force couple (TFC) between the anterior and posterior rotator cuff muscles, may have a role in the pathogenesis of the type B morphology. The purpose of this study was to determine whether there is a TFC imbalance in the Walch type B shoulder using an imaging-based 3-dimensional (3D) volumetric and fatty infiltration assessment of segmented rotator cuff muscles. METHODS: Computed tomography images of 33 Walch type A and 60 Walch type B shoulders with the complete scapula and humerus including the distal humeral epicondyles were evaluated. The 3D volumes of the entire subscapularis, supraspinatus, and infraspinatus-teres minor (Infra-Tm) were manually segmented and analyzed. Additionally, anthropometric parameters including glenoid version, glenoid inclination, posterior humeral head subluxation, and humeral torsion were measured. The 3D muscle analysis was then compared with the anthropometric parameters using the Wilcoxon rank sum and Kruskal-Wallis tests. RESULTS: There were no significant differences (P > .200) in muscle volume ratios between the Infra-Tm and the subscapularis in Walch type A (0.93) and type B (0.96) shoulders. The fatty infiltration percentage ratio, however, was significantly greater in type B shoulders (0.94 vs. 0.75, P < .001). The Infra-Tm to subscapularis fatty infiltration percentage ratio was significantly larger in patients with >75% humeral head subluxation than in those with 60%-75% head subluxation (0.97 vs. 0.74, P < .001) and significantly larger in patients with >25° of retroversion than in those with <15° of retroversion (1.10 vs. 0.75, P = .004). The supraspinatus fatty infiltration percentage was significantly lower in Walch type B shoulders than type A shoulders (P = .004). Walch type A shoulders had mean humeral retrotorsion of 22° ± 10° whereas Walch type B shoulders had humeral retrotorsion of only 14° ± 9° relative to the epicondylar axis (P < .001). CONCLUSION: The TFC is in balance in the Walch type B shoulder in terms of 3D volumetric rotator cuff muscle analysis; however, the posterior rotator cuff does demonstrate increased fatty infiltration. Posterior humeral head subluxation and glenoid retroversion, which are pathognomonic of the Walch type B shoulder, may lead to a disturbance in the length-tension relationship of the posterior rotator cuff, causing fatty infiltration.

Upper Limb Lengthening in Achondroplasia Using Unilateral External Fixation.

PURPOSE: The purpose of this study was to analyze the long-term results of humeral lengthening in achondroplastic patients and make suggestions on the most appropriate surgical technique to improve patient outcomes. METHODS: Fifty-four humeral lengthening procedures performed in 27 achondroplastic patients were reviewed. Elongations were performed by means of callotasis with unilateral external fixation. Inclusion criteria were: achondroplastic patients under 17 years without prior arm operations and minimum follow-up of 36 months. RESULTS: Fifty humeri in 25 patients (13 men and 12 women), aged between 9 and 17 years, met the inclusion criteria. Mean humeral lengthening was 8.82 cm (range: 5 to 10.5 cm), which represented an elongation of 54.80% (range: 46% to 63%) of the original length. The healing index was 0.91 months (range: 0.72 to 1.4 mo) per centimeter gained. Shoulder and elbow range of motion and stability were preserved in 47 limbs. Noncomplicated cases consistently experienced a significant functional improvement in the performance of activities of daily living such as putting on footwear and personal hygiene. Short-term complications included 11 pin-tract infections, 1 radial nerve neuropraxia, and 1 failure of the regenerated bone formation. None of these complications prevented from completion of treatment. Long-term complications included 2 cases of nonunion, 3 elbow flexion contractures, and 2 cases of psychological dissatisfaction, all of them in 4 patients. Factors associated with long-term complications were intraoperative fragment displacement and distal humeral osteotomy. No fractures of the regenerated bone were identified in the long term. CONCLUSIONS: Callotasis with unilateral external fixation is a reliable and well-tolerated procedure for humeral lengthening in achondroplastic patients, with an acceptable complication rate. Guided fixator placement and a proximal humeral osteotomy are strongly recommended technical tips as they may help prevent complications and improve outcomes. LEVEL OF EVIDENCE: Level IV-case series.

Impact of humeral and glenoid component variations on range of motion in reverse geometry total shoulder arthroplasty: a standardized computer model study.

BACKGROUND: Multiple modifications of reverse total shoulder arthroplasty (RTSA) since the first Grammont design have developed to improve range of motion (ROM) and avoid notching. The effect of these changes in shoulder kinematics and the best compromise for ROM is still under debate. This computer simulation study evaluates the influence of humeral design, humeral neck-shaft angle (NSA), glenoid lateralization, and glenoid eccentricity on ROM of RTSA. METHODS: We created a 3-dimensional computer model from computed tomography scans of 13 patients with primary osteoarthritis simulating implantation of a standardized reverse shoulder arthroplasty. We analyzed the effect of 4 different variables on impingement-free ROM: humeral design (inlay vs. semi-inlay vs. onlay), humeral NSA (135° vs. 145° vs. 155°), glenoid lateralization, and glenoid eccentricity on ROM. RESULTS: The use of different humeral stem designs did not have a significant effect on total global ROM. Reducing NSA demonstrated a significant increase in adduction, and external and internal rotation in adduction, whereas a decrease in abduction and external rotation in abduction. Glenosphere lateralization was the most effective method for increasing total global ROM (P < .0001); however, extreme lateralization (+12 mm) did not show significant benefit compared with moderate lateralization (+4 mm). Glenosphere eccentricity increased only adduction and internal rotation in adduction. CONCLUSION: Only glenoid lateralization has a significant effect on increasing total global ROM in RTSA. The use of the semi-inlay 145° model combined with 4 mm lateralization and 2 mm inferior eccentricity represents the middle ground and the most universal approach in RTSA.

Update on premature physeal closure. Diagnosis and treatment.

PURPOSE OF REVIEW: Premature Physeal Closure (PPC) is the most common consequence of a mostly posttraumatic, physeal injury. They are of utmost importance because they can significantly alter physeal function and lead to disorders such as limb length discrepancies and angular deformities. RECENT FINDINGS: The type of physeal fracture has not demonstrated a solid predictive value in the formation of PPC, especially in the knee where almost any type of fracture can produce it. The detection of physeal damage with imaging tests (simple radiology and MRI) is very accurate; however, their predictive capacity to foretell which injury will generate a physeal bridge is still poor. For this reason, it is not advisable to make surgical decisions at the first medical assessment. Direct surgical management of PPC's (resection-interposition technique) has generally shown high unpredictability. Nevertheless, the latest interposition materials (chondrocytes and mesenchymal stem cells) showed promising results. SUMMARY: PPC is an often devastating consequence of physeal injury and as such deserves further research. To date little is known about etiopathogenesis, risk factors and natural history among other aspects. Until direct surgery offers more consistent results, acute osteotomies and bone distraction for progressive correction continue to be the most widespread treatments for PPCs.

The unstable os acromiale: a cause of pain in the young athlete.

PURPOSE: Os acromiale is a common entity in the middle-age group, in whom it is frequently associated with rotator cuff tears. However, it can be a cause of shoulder pain in the young athletes. We want to increase awareness of this pathology that may occultly affect the young athlete as well as to present the results of a perfusion-preserving arthrodesis. METHODS: Four consecutive young patients (17-21 years old) with a history of at least 6 months of unrecognized shoulder pain were surgically treated for os acromiale. Through a superior approach, stabilization of the neo-joint by means of cannulated screws and autogenic graft augmentation was performed. RESULTS: Union of the os acromiale was achieved in all the patients. They had an excellent functional outcome, reaching all the maximum Simple Shoulder Test (12) and Oxford shoulder Score (48) scores. All the patients were able to return to their previous sports level. CONCLUSION: Awareness of the os acromiale in the young athlete, appropriate clinical examination, and image studies are crucial to confirm diagnosis. Surgical treatment aiming at fusion in situ has shown excellent result.

Artroplastia de resección de hombro como salvamento para infecciones recalcitrantes: estado actual de la técnica a propósito de dos casos / Shoulder resection arthroplasty as a salvage procedure for recalcitrant infections: current state of the art regarding two cases

INTRODUCCIÓN Y OBJETIVOS La artroplastia de resección de hombro (ARH) se presenta como una técnica obsoleta y una opción no válida en la actualidad, debido a la evolución de las técnicas quirúrgicas y de los implantes. Pero, como consecuencia del aumento exponencial del uso de artroplastias de hombro, están aumentando en paralelo el número de fracasos e infecciones, con necesidad de revisión y rescate. Es por ello que, en determinadas situaciones y pacientes, esa técnica vuelve a ser una opción necesaria como salvataje, aunque tiene un alto coste funcional. El objetivo de nuestro trabajo, es presentar dos casos de artroplastia de resección de hombro como una opción válida de tratamiento en la actualidad y la revisión de la literatura. CASOS Se presentan dos casos de ARH como tratamiento de rescate, en un caso de osteomielitis crónica de cabeza humeral y un caso de infección de hemiartroplastia de hombro. Ambos pacientes se encontraban sin dolor y libres de infección con un seguimiento de más de 30 meses. En un caso la funcionalidad fue limitada con un Constant de 45 pero el otro caso la funcionalidad fue aceptable con un Constant de 67. CONCLUSIONES La ARH sigue siendo una técnica útil tras el fracaso de procedimientos de revisión, para resolver infecciones protésicas recalcitrantes u osteomielitis. Los resultados funcionales son pobres, por lo que debe reservarse para pacientes con baja demanda funcional y como salvataje, tras agotar otras opciones.

INTRODUCTION AND OBJECTIVES shoulder resection arthroplasty (SRA) is currently considered as an outdated technique, due to the advances in surgical techniques and new prosthesis designs. However, with the exponential increase in the use of shoulder arthroplasties, the number of failures and infections is equally increasing, as well as the revisions and salvage procedures. In certain situations, SRA is therefore a necessary solution, although it grossly compromise shoulder function. The aim of our study is to present two cases who underwent SRA as a valid treatment option nowadays and a literature review. CASES We present two cases of SRA as salvatage treatment. First case in a chronic humeral head osteomyelitis and second in a partial shoulder prosthesis recalcitrant infection. Both patients had complete pain relief and infection was solved with a follow-up over 30 months. In the first case, postoperative shoulder function was limited with a Constant­Murley score of 45. In the second case, function was fairly good with a Constant of 67. CONCLUSIONS SRA remains a valuable technique after the failure of revision procedures, as a salvage for recalcitrant prosthetic infections or osteomyelitis. The functional results are poor, so it should be reserved for patients with low functional demand and as salvatage procedure, after assess other options.

Free Vascularized Fibular Graft for Reconstruction of the Lateral Clavicle: A Case Report and Review of the Literature.

CASE: A 50-year-old female patient presented with significant (40%) bone loss of the lateral clavicle extending to the acromioclavicular (AC) joint, as a result of multiple, failed revision surgeries following a fracture-dislocation. She was treated with a free vascularized fibular graft and biplanar stabilization of the AC joint. At 4 years of follow-up, the patient had experienced resolution of painful symptoms with a Constant-Murley score of 72. CONCLUSIONS: Reconstruction of large, lateral clavicle defects with a free vascularized fibular graft and biplanar stabilization of the AC joint may provide a satisfactory clinical outcome.

Lateral circumflex femoral artery false aneurysm as a complication of intertrochanteric hip fracture with displaced lesser trochanter.

We present a patient who suffered an unstable intertrochanteric hip fracture and underwent osteosynthesis with a trochanteric nail. During the postoperative period, he presented a pseudoaneurysm of the lateral circumflex branch of the deep femoral artery secondary to a displaced fracture of the lesser trochanter. With the suspected diagnosis due to indirect clinical and radiological signs and confirmation by Doppler ultrasound and computed tomography angiography, a transverse arterial embolization with resolution of the symptoms was carried out. The pseudoaneurysm of the deep femoral artery or its branches is a very rare complication after intertrochanteric hip fractures, which must be taken into account in the late appearance of edema and hematoma in the thigh and evidence of medial and superior displacement of the lesser trochanter. The diagnosis is confirmed by CT angiography and the treatment by percutaneous arterial embolization has good results without the need of excising the lesser trochanter.

One-Stage Total Knee Arthroplasty Plus Corrective Osteotomy for Osteoarthritis Associated With Severe Extra-articular Deformity.

The mainstay for treatment of articular deformity caused by advanced tricompartmental osteoarthritis of the knee is total knee arthroplasty. When this is also associated with an extra-articular deformity, this also must be compensated or corrected. In this scenario, it is essential to achieve an optimal mechanical situation by restoring the anatomical and mechanical limb axes and an adequate soft-tissue balance. These premises are necessary to relieve pain and achieve satisfactory functionality and implant survival over time. A reconstructive single-stage technique is proposed for patients with knee osteoarthritis amenable to arthroplasty and a severe extra-articular deformity, aiming at addressing both problems simultaneously.

All-Arthroscopic, 270° Reconstruction of the Inferior Glenohumeral Ligament With Palmaris Longus Autograft.

Numerous factors play a role in anterior shoulder stability. The inferior glenohumeral ligament, especially the anterior band, is the main passive anterior stabilizer in the end range of motion. Surgical treatment of this pathology continues to be a challenge in patients with capsular deficiency, in whom the recurrence rate of soft-tissue arthroscopic repair increases significantly. There is not yet a fair solution for these patients without glenoid bone loss, in whom the poor tissue quality determines recurrent instability. We present an all-arthroscopic technique for reconstruction of the inferior glenohumeral ligament by means of palmaris longus autograft as an alternative to nonanatomic bone block procedures.

Update on treatment of adolescent Blount disease.

PURPOSE OF REVIEW: Treatments available to correct adolescent Blount disease deformities differ in terms of features, advantages, and disadvantages. Each is indicated, therefore, for different scenarios of severity, physeal condition, and maturity. The purpose of this review is to update basic concepts, surgical treatments, and controversies concerning this disorder. RECENT FINDINGS: The cause of Blount disease is unknown although etiologic factors as morbid obesity and hypovitaminosis D are thought to be associated with it. Recently, semiinvasive techniques (guided growth) have been proposed for mild deformities but remain controversial. Osteotomies with external fixation (hexapodes) are still the most recommended corrective treatment in this condition. SUMMARY: Little is known about the origin and natural history of Blount disease. Treatment is always surgical and, given their complexity, should be preceded by a thorough analysis and planning regarding all deformities. Treatment principles are to correct the three-dimensional deformity and avoid recurrence. The choice of technique mainly depends on patient maturity and severity. Guided growth is a good choice for more immature patients with moderate deformities. Progressive correction using osteotomy or physeal distraction is indicated for patients with severe deformities and low remaining growth. The Taylor spatial frame is currently the most popular progressive correction device.

Simultaneous Ipsilateral Dislocation of the Hip and the Knee: A Case Report.

CASE: A patient was struck by an agricultural vehicle and sustained ipsilateral hip and knee dislocations. Closed reduction of the hip was accomplished in the emergency department; the patient required general anesthesia in the operating room to reduce the knee dislocation. Nonoperative treatment was used for both injuries, with a good long-term outcome. CONCLUSION: Simultaneous ipsilateral hip and knee dislocations are rare and complex injuries that usually result from high-energy trauma. In order to avoid severe neurovascular complications, they need prompt management. Nonoperative treatment followed by an intensive rehabilitation program should be considered as an alternative treatment to surgery in older patients with a low-demand lifestyle.
