Cemented radial head arthroplasty: Does radiographic loosening have an effect on clinical and functional outcomes? Average 10 years' results.

PURPOSE: The aim of this study was to evaluate the possible effect of radiographic loosening on clinical and functional outcomes, while presenting the mid-term radiographic and functional outcomes of cemented, monopolar RHA applied to patients with comminuted radial head fractures. METHODS: We performed a retrospective study by evaluating the records of patients who were diagnosed in a single center with radial head fractures between 2001 and 2013. Twenty-six patients with comminuted radial head fractures with a mean age of 48.9 and a mean follow-up time of 132.2 months were included. The radiographic evaluation was performed by assessing peri-prosthetic radiolucent lines around the stem to evaluate loosening, while the clinical evaluation was performed by utilizing elbow range of motion (ROM), Mayo elbow performance score (MEPS), Oxford elbow score (OES) and quick-DASH scores. RESULTS: 13 patients (Group 1) with peri-prosthetic stem lucency were defined as radiographic loosening (50%), while the remaining 13 patients (Group 2) were not detected to have stem lucency. One patient in group 1 also had concomitant pain and underwent removal of the prosthesis, while 12 patients (92.3%) remained pain-free. On the latest follow-up visit, there was no significant difference between the groups regarding ROM, MEPS, OES and quick-DASH scores. CONCLUSIONS: Within ten years following surgery, half of the patients with radial head prostheses were noted to show radiographic signs of loosening which did not have any major negative effect in terms of clinical-functional outcomes and quality of life, except requiring the removal of the implant in one patient. LEVEL OF EVIDENCE: Level III.

A Clinical Comparison of Home-Based and Hospital-Based Exercise Programs Following Arthroscopic Capsulolabral Repair for Anterior Shoulder Instability.

CONTEXT: Ideal rehabilitation method following arthroscopic capsulolabral repair surgery for anterior shoulder instability has not been proven yet. Although rapid or slow protocols were compared previously, home- or hospital-based protocols were not questioned before. OBJECTIVE: The aim of this prospective unrandomized controlled clinical trial is to compare the clinical outcomes of home-based and hospital-based rehabilitation programs following arthroscopic Bankart repair. DESIGN: Nonrandomized controlled trial. SETTING: Orthopedics and physical therapy units of a single institution. PATIENTS: Fifty-four patients (49 males and 5 females) with an average age of 30.5 (9.1) years, who underwent arthroscopic capsulolabral repair and met the inclusion criteria, with at least 1-year follow-up were allocated into 2 groups: home-based (n = 33) and hospital-based (n = 21) groups. INTERVENTIONS: Both groups received identical rehabilitation programs. Patients in the home-based group were called for follow-up every 3 weeks. Patients in the hospital-based group admitted for therapy every other day for a total of 6 to 8 weeks. Both groups were followed identically after the eighth week and the rehabilitation program continued for 6 months. MAIN OUTCOME MEASURES: Clinical outcomes were assessed using Disabilities of Arm Shoulder Hand, Constant, and Rowe scores. Mann-Whitney U test was used to compare the results in both groups. Wilcoxon test was used for determining the progress in each group. RESULTS: Groups were age and gender matched (P = .61, P = .69). Average number of treatment sessions was 13.8 (7.3) for patients in the hospital-based group. Preoperative Disabilities of Arm Shoulder Hand (27.46 [11.81] vs 32.53 [16.42], P = .22), Constant (58.23 [14.23] vs 54.17 [10.46], P = .13), and Rowe (51.72 [15.36] vs 43.81 [19.16], P = .12) scores were similar between groups. Postoperative scores at sixth month were significantly improved in each group (P = .001, P = .001, and P = .001). No significant difference was observed between 2 groups regarding clinical scores in any time point. CONCLUSIONS: We have, therefore, concluded that a controlled home-based exercise program is as effective as hospital-based rehabilitation following arthroscopic capsulolabral repair for anterior shoulder instability.

Arthroscopic versus open release of internal rotation contracture in the obstetrical brachial plexus paralysis (OBPP) sequela.

BACKGROUND: Latissimus dorsi (LD) and teres major (TM) tendon transfers are effective surgical procedures to improve shoulder abduction and external rotation for children with obstetrical brachial plexus palsy (OBPP). Open pectoralis major (PM) tendon Z-plasty and arthroscopic subscapularis (SS) release are 2 options for the release of internal rotation contractures to enhance muscle transfers. This study compared the functional results of LD and TM tendon transfers with open PM tendon Z-plasty or arthroscopic SS release. METHODS: The study included 24 patients who underwent LD and TM tendon transfers for OBPP (9 arthroscopic SS release, 15 open PM tendon Z-plasty) with a mean follow-up of 41.33 months (range, 36-60 months) and 47.2 months (range, 36-60 months), respectively. Functional evaluation was made according to range of motion and Mallet scoring system. RESULTS: Shoulder abduction-external rotation degrees and scores in all sections of the Mallet scoring system significantly increased in both groups (P < .001). Postoperatively, the arthroscopic SS release group had significantly better abduction degrees (P = .003), total Mallet scores (P < .001), and superior abduction (P = .043), active external rotation (P = .043), hand-to-head (P = .043), and hand-to-mouth (P < .001) scores for the Mallet scoring system. DISCUSSION: Transfer of LD together with TM tendons combined with one of the internal rotation contracture release procedures yielded good clinical and functional results in patients younger than age 7, regardless of the type of release method. However, arthroscopic SS release, although requiring an experienced surgeon, revealed better clinical and functional outcomes and is considered to be a less invasive and superior method.

Latarjet procedure using subscapularis split approach offers better rotational endurance than partial tenotomy for anterior shoulder instability.

PURPOSE: Latarjet, which is a coracoid bone block procedure, is an effective treatment for anterior shoulder instability with glenoid bone loss. During this reconstructive procedure the subscapularis may be tenotomized or be split to expose the glenoid neck. The aim of this study was to assess the effect of subscapularis management on functional outcomes and internal and external rotation durability and strength. Hypothesis is that the subscapularis split approach will result in better functional results and superior internal rotation strength and endurance. METHODS: The study included 48 patients [median age 30 (range 16-69); 42 males, 6 females], who underwent a modified Latarjet procedure for anterior shoulder instability. There were 20 patients in the subscapularis tenotomy group and 28 patients in the subscapularis split group. The groups were compared isokinetically using a computerized dynamometer for internal and external rotation durability and strength. At the latest follow-up, the patients were evaluated with the American Shoulder and Elbow Surgeons (ASES) and ROWE scores for functional outcomes. RESULTS: At a median follow-up period of 25 (range 12-73) months after the Latarjet procedure, the internal rotation durability was significantly higher in the split group (p = 0.045). However, a statistically significant difference could not be found for internal and external rotational strengths (n.s.). There was also no significant difference between the final ASES and ROWE scores (n.s.). CONCLUSION: Although both approaches offer promising results, the subscapularis split approach appears to provide better internal rotation durability compared to subscapularis tenotomy. Therefore, the subscapularis split approach may be more preferable for the management of the subscapularis muscle during Latarjet procedure. LEVEL OF EVIDENCE: Retrospective cohort study, Level III.

Can Normal Fracture Healing Be Achieved When the Implant Is Retained on the Basis of Infection? An Experimental Animal Model.

BACKGROUND: Infection after open fractures is a common complication. Treatment options for infections developed after intramedullary nailing surgery remain a topic of controversy. We therefore used a rat fracture model to evaluate the effects of infection on osseous union when the implant was maintained. QUESTIONS/PURPOSES: In a rat model, (1) does infection alter callus strength; (2) does infection alter the radiographic appearance of callus; and (3) does infection alter the histological properties of callus? METHODS: An open femoral fracture was created and fixed with an intramedullary Kirschner wire in 72 adult male Sprague-Dawley rats, which were divided into two study groups. In the infection group, the fracture site was contaminated with Staphylococcus aureus (36 animals), whereas in the control group, there was no bacterial contamination (36 animals). No antibiotics were used either for prophylaxis or for treatment. We performed biomechanical (maximum torque causing failure and stiffness), radiographic (Lane and Sandhu scoring for callus formation), and histologic (scoring for callus maturity) assessments at 3 and 6 weeks. The number of bacteria colonies on the femur, wire, and soft tissue inside knee were compared to validate that we successfully created an infection model. The number of bacteria colonies in the soft tissue inside the knee was higher in the infection group after 6 weeks than after the third week, demonstrating the presence of locally aggressive infection. RESULTS: Infection decreased callus strength at 6 weeks. Torque to failure (299.07 ± 65.53 Nmm versus 107.20 ± 88.81, mean difference with 95% confidence interval, 192 [43-340]; p = 0.007) and stiffness at 6 weeks (11.28 ± 2.67 Nmm versus 2.03 ± 1.68, mean difference with 95% confidence interval, 9 [3-16]; p = 0.004) both were greater in the control group than in the group with infection. Radiographic analysis at 6 weeks demonstrated the fracture line was less distinct (Lane and Sandhu score of 2-3) in the infection group and complete union was observed (Lane and Sandhu score of 3-4) in the control group (p = 0.001). Semiquantitative histology scores were not different between the noninfected controls and the rats with infection (score 10 versus 9). CONCLUSIONS: Retaining an implant in the presence of an underlying infection without antibiotic treatment leads to weaker callus and impedes callus maturation compared with noninfected controls in a rat model. Future studies might evaluate whether antibiotic treatment would modify this result. CLINICAL RELEVANCE: This model sets the stage for further investigations that might study the influence of different interventions on fracture healing in implant-associated osteomyelitis. Future observational studies might also evaluate the histological properties of callus in patients with osteomyelitis.

Nonoperative treatment of frozen shoulder: oral glucocorticoids.

PURPOSE: The aim of this study was to report our results of glucocorticoid therapy combined with pregabalin and a home exercise program in patients with frozen shoulder. METHODS: Thirty-three patients (seven males, 26 females; mean age 52, range 43-71) diagnosed with primary idiopathic frozen shoulder were included in the study. Secondary causes and systemic diseases related to frozen shoulder were excluded. Administration of 0.5 mg/kg/day methylprednisolone was halved each week and ceased at the end of first month. Pregabalin, paracetamol and proton pump inhibitor was also included in the treatment. Physical therapy as a home program was initiated as the pain subsided. Patients were evaluated using the Constant, DASH and ASES scores in the sixth week and first year. Pain was evaluated with VAS and range of motion at each visit. RESULTS: Patients were followed up for an average period of 21 months (range 12-37). No adverse effect related to glucocorticoid therapy was observed during the treatment. The DASH, ASES and Constant scores improved significantly in the sixth week and first year (p > 0.05). Average range of motion and pain improved significantly every week until full recovery (p > 0.05). CONCLUSION: Glucocorticoid therapy combined with pregabalin and a home exercise program is an effective treatment in the first stage of frozen shoulder.

Time-dependent changes after latissimus dorsi transfer: tenodesis or tendon transfer?

BACKGROUND: Transfer of the latissimus dorsi tendon to the posterosuperior part of the rotator cuff is an option in active patients with massive rotator cuff tears to restore shoulder elevation and external rotation. However, it is unknown whether this treatment prevents progression of cuff tear arthropathy. QUESTIONS/PURPOSES: The purpose of this study was to determine whether the observed improvement in shoulder function in the early postoperative period with latissimus dorsi tendon transfer for irreparable rotator cuff tears will be permanent or will deteriorate in the midterm period (at 1-5 years after surgery). METHODS: During a 6-year period, we performed 11 latissimus dorsi tendon transfers in 11 patients for patients with massive, irreparable, chronic tears of the posterosuperior part of the rotator cuff (defined as > 5 cm supraspinatus and infraspinatus tendon tears with Goutallier Grade 3 to 4 fatty infiltration on MRI), for patients who were younger than 65 years of age, and had high functional demands and intact subscapularis function. No patients were lost to followup; minimum followup was 12 months (median, 33 months; range, 12-62 months). The mean patient age was 55 years (median, 53 years; range, 47-65 years). Shoulder forward elevation, external rotation, and Constant-Murley and American Shoulder and Elbow Surgeons scores were assessed. Pain was assessed by a 0- to 10-point visual analog scale. Acromiohumeral distance and cuff tear arthropathy (staged according to the Hamada classification) were evaluated on radiographs. RESULTS: Shoulder forward elevation, external rotation, Constant-Murley scores, and American Shoulder and Elbow Surgeons scores improved at 6 months. However, although shoulder motion values and Constant-Murley scores remained unchanged between the 6-month and latest evaluations, American Shoulder and Elbow Surgeons scores decreased in this period (median, 71; range, 33-88 versus median, 68; range, 33-85; p = 0.009). Visual analog scale scores improved between the preoperative and 6-month evaluations but then worsened (representing worse pain) between the 6-month and latest evaluations (median, 2; range, 0-5 versus median, 2; range, 1-6; p = 0.034), but scores at latest followup were still lower than preoperative values (median, 7; range, 4-8; p = 0.003). Although acromiohumeral distance values were increased at 6 months (median, 8 mm; range, 6-10 mm; p = 0.023), the values at latest followup (median, 8 mm; range, 5-10 mm) were no different from the preoperative ones (mean, 7 mm; range, 6-9 mm; p > 0.05). According to Hamada classification, all patients were Grade 1 both pre- and postoperatively, except one who was Grade 3 at latest followup. CONCLUSIONS: The latissimus dorsi tendon transfer may improve shoulder function in irreparable massive rotator cuff tears. However, because the tenodesis effect loses its strength with time, progression of the arthropathy should be expected over time. Nevertheless, latissimus dorsi tendon transfer may help to delay the need for reverse shoulder arthroplasty for these patients. LEVEL OF EVIDENCE: Level IV, therapeutic study.

Translation, cultural adaptation, validity and reliability of the Turkish ASES questionnaire.

PURPOSE: The American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) is a standard shoulder assessment form, which is comprised of objective and subjective sections and prepared by shoulder and elbow surgeons. The purpose of this study was to translate the subjective part of the ASES into Turkish and establish its cultural adaptiveness and validity. METHODS: The original version of the ASES was translated into Turkish in accordance with the stages recommended by Guillemin. Sixty-three patients (average age: 48.2 ± 13.4; range: 18-74 years) suffering from different shoulder complaints were included in the study. The ASES was completed twice at 3- to 7-day intervals for test-retest reliability. The intraclass correlation coefficient was used to calculate the test-retest reliability, and Cronbach's alpha was used for internal consistency. Patients were asked to complete the short form 36 (SF-36) and the Shoulder Pain and Disability Index (SPADI) for correlation. Validity was evaluated by external correlation of the ASES with the SPADI and SF-S6 questionnaire, which may also be defined as 'construct validity'. The results were analysed using Pearson's correlation test. RESULTS: The test-retest reliability of the ASES pain and function subscales and total ASES score were 0.95, 0.86 and 0.94, respectively. Cronbach's alpha coefficient for the total ASES was 0.88. The correlation between the total ASES and total SPADI score was -0.82; the correlation coefficient between the ASES pain subscale and SPADI pain subscale was -0.79 (p < 0.000); and the correlation between the ASES and SPADI function subscales were -0.53 (p < 0.000). The highest correlation was between ASES and SF-36 bodily pain, as well as ASES and SF-36 mental health (r = 0.64, r = 0.56, p < 0.000), and the lowest correlations were between ASES and the SF-36 physical component score and between ASES and SF-36 social function (r = 0.28, r = 0.33 p < 0.000). CONCLUSION: The Turkish version of the ASES is a valid and reliable shoulder assessment form that can be used for numerous shoulder disorders. LEVEL OF EVIDENCE: III.

Coronal plane fractures of the distal humerus involving the capitellum and trochlea treated with open reduction internal fixation.

INTRODUCTION: Coronal plane fractures of the distal humerus involving the capitellum and trochlea are rare. Treatments have evolved from closed reduction to open reduction and internal fixation (ORIF) to achieve a stable joint that allows early mobilization. BACKGROUND: We determined the functional outcomes of treating coronal plane fractures of the distal humerus with ORIF. METHODS: We reviewed the records of all patients with coronal plane fractures of the distal humerus treated by ORIF. Fractures were classified according to Bryan and Morrey. Cannulated screws were used for fixation. All patients were evaluated using the Mayo Elbow Score Performance Index (MEPI) and disabilities of the arm, shoulder, and hand (DASH) scores at least 1 year later. RESULTS: Of the 18 patients evaluated (12 women), the mean (SD) age was 45.3(16.5) years (range 16-70). There were seven Type-I, five Type-III, and six Type-IV fractures. Mean follow-up was 43.6 (38.1) months (range 12-120). The mean elbow range of motion in sagittal plane at last follow-up ranged from 8.9° to 132.8°. The mean MEPI score was 86.7 (15.2) points (range 60-100), corresponding to 12 excellent, 2 good, and 4 fair outcomes. The mean DASH score was 15.3 (13.5) points (range 17-35.8). Heterotrophic ossification developed in one patient with delayed fixation; 14 patients with excellent or good results returned to their previous activity levels. Functional scores did not differ by age, sex, or fracture types (P > 0.05 for all comparisons). CONCLUSION: ORIF with cannulated screws, which maintain a stable anatomic articular position, provides satisfactory results in coronal plane fractures of the distal humerus. LEVEL OF EVIDENCE: Level IV case series.

Pure elbow dislocation in a child wrestler with underlying hyperlaxity: What is the optimal time to return to competition?

Elbow dislocations are often considered serious injuries that can cause a child athlete to miss the entire season in wrestling. It was reported that the return to sports after the elbow dislocation was between 6 and 12 months in child wrestlers. In some cases, underlying hyperlaxity may have an essential role in the occurrence of pure elbow dislocation without any ligament injury. We report the case of a 10-year-old boy patient who had pure elbow dislocation following falling onto an outstretched hand in a wrestling match. Because the physical examination findings of the patient indicated the presence of hyperlaxity, the patient was treated by closed reduction, short-term immobilization, and early strengthening of the dynamic stabilizers. This case report's findings suggest that detecting the presence of hyperlaxity in this specific patient group is crucial since this patient group has the potential to return to competitions 6 weeks after injury, unlike patients without hyperlaxity.

Are critical shoulder angle and acromion index correlated to the size of a rotator cuff tear.

PURPOSE: Scapular morphology is an extrinsic factor playing role in rotator cuff tear (RCT) etiology. The objective of this study was to evaluate the relationship between critical shoulder angle (CSA) and acromion index (AI) with partial-bursal side and full thickness RCT and the size of the RCT. HYPOTHESIS: The hypothesis was that CSA and AI would be greater in partial bursal-side RCT and full-thickness RCT patients and would increase with the size of the RCT. METHODS: This retrospective study assessed 218 patients who had standard shoulder radiographs and magnetic resonance imaging. Patients were divided into three groups: intact rotator cuff (68), partial bursal-side RCT (34) and full-thickness RCT (116). In the second part, full-thickness RCT patients were divided into four groups according to RCT size; small (<1cm), medium (1-3cm), large (3-5cm) and massive (>5cm). AI and CSA measurements were evaluated from radiographs. RESULTS: The mean CSA was 32.8̊ in control group, 34.3̊ in partial group and 36.9̊ in full-thickness group. The mean AI was 0.66, 0.68 and 0.72 respectively. Significant difference was found in AI and CSA between full thickness RCT and intact RC group (p<0.01), and partial RCT and full thickness RCT group (p<0.05) in paired comparisons. In full thickness RCT size groups the mean CSA was 34.2̊, 36.4̊, 39.0̊ and 40.8̊ and mean AI was 0.70, 0.71, 0.73 and 0.79 respectively. Significant difference was found between small-large, small-massive, medium-massive groups for CSA in paired comparisons and between small-massive, medium-massive groups for AI. CONCLUSION: CSA and AI were significantly greater in full-thickness RCT patients and the size of the RCT increased with CSA and AI. The greater CSA and AI could be predictors for larger RCT.

Transfer of latissmus dorsi and teres major tendons without subscapularis release for the treatment of obstetrical brachial plexus palsy sequela.

BACKGROUND: Patients with obstetrical brachial plexus palsy (OBPP) sequela exhibit adduction and internal rotation contractures. The muscular imbalance may result in secondary bony changes. Tendon transfers and muscular releases may improve shoulder function in these patients. The aim of this study is to evaluate the functional and radiological results of pectoralis major tendon Z-plasty with transfer of latissimus dorsi and teres major tendons to rotator cuff tendons without release of subscapularis muscle in patients with mild sequela of OBPP. MATERIALS AND METHODS: Twenty-six consecutive patients, who were treated with tendon transfer and met the eligibility criteria, were included in the study. No additional humeral osteotomy or subscapularis tenotomy was performed. Functional evaluation is made according to range of motion and Mallet scoring system. Preoperative radiologic evaluation was made according to the grading system of Waters. RESULTS: A significant increase in shoulder function was found in all patients. Postoperative radiographs revealed glenohumeral congruity was maintained in all patients. Improvement in shoulder abduction and external rotation was higher in patients who were operated before the age of 7. DISCUSSION/CONCLUSION: Pectoralis major tendon lengthening with transfer of latissimus dorsi and teres major tendons to rotator cuff is an effective and reproducible technique and can improve shoulder functions in patients with OBPP. Subscapularis release is not always required to overcome internal rotation contracture. Secondary glenohumeral changes might also be prevented with this approach.

Reverse total shoulder arthroplasty for failed treatment of proximal humerus fractures.

OBJECTIVE: The aim of this study was to evaluate the functional and radiological outcomes and complications of reverse total shoulder arthroplasty (RTSA) for failed treatment of proximal humerus fractures (FTPHF). METHODS: In this retrospective study, 20 patients (17 female, 3 male; mean age = 71.35 years; age range = 54-81 years) who underwent RTSA for FTPHF between 2012 and 2018 were included. The mean follow-up was 37.85 (range: 24-83) months. Outcome measures included shoulder range of motion, Constant score, ASES (American Shoulder and Elbow Surgeons) score, visual analog scale (VAS). Intra-or post-operative complications were also recorded. RESULTS: The mean anterior flexion and external rotation improved from 37.25°±10.59° and 11.05°±4.79° preoperatively to 105.53° ± 9.33 and 22.37° ± 4.12° postoperatively, respectively (P < 0.01 for both). The mean Constant and ASES scores ameliorated from 21.95 ± 3.57 and 18.15 ± 4.69 preoperatively to 61.7 ± 7.6 and 71.18 ± 4.69 at the final follow-up, respectively (P < 0.01 for both). VAS significantly reduced from 6.83 ± 2.04 preoperatively to 1.79 ± 0.61 at the final follow-up (P < 0.01). None of the patients had major complications or required revision. CONCLUSION: Treatment with the RTSA for the FTPHF seems to be an effective treatment method that can provide satisfactory radiological and functional outcomes with low complication rates. LEVEL OF EVIDENCE: Level IV, Therapeutic Study.

Surgical management of sacral chordoma.

Treatment results of 17 patients who were diagnosed with sacral chordoma between 1993 and 2007, were analyzed retrospectively. The mean duration of symptoms was 30.2 months. The mean tumour size was 10.7 cm; the location was S2 or more proximal in ten-patients. A wide resection was achieved in 14 patients, a marginal resection in one patient and two patients had intralesional excision. Seven patients had a recurrence after a mean time interval of 36.3 months. Wound dehiscence and infection were the major problems. Four patients required continuous urinary catheterization because of incontinence, and ten patients had colostomy or ileostomy simultaneously with tumour resection. This study showed that tumour size and a wide surgical margin are importance factors for survival in chordoma patients. Use of a combined anterior and posterior approach could increase the chance of achieving a wide margin. A multidisciplinary approach is required to achieve this goal.

Functional Outcomes and Complications Following Scapulothoracic Arthrodesis in Patients with Facioscapulohumeral Dystrophy.

BACKGROUND: Facioscapulohumeral dystrophy (FSHD) is an autosomal-dominant myopathy characterized by facial and shoulder girdle muscle weakness with scapular winging. Scapulothoracic arthrodesis is a successful treatment approach for patients with <90° of shoulder elevation. The purpose of the present study was to assess functional outcomes and complications following scapulothoracic arthrodesis in patients with FSHD. METHODS: We retrospectively reviewed the records of 40 patients (64 shoulders) in whom scapulothoracic arthrodesis was performed. To achieve fusion, multiple multifilament cables were used together with autologous bone and allograft bone. Preoperative and postoperative shoulder elevation and abduction; Disabilities of the Arm, Shoulder and Hand (Quick version, qDASH) scores; and pulmonary function were compared. Recorded complications were classified as pulmonary or scapular. RESULTS: The mean age of the patients at the time of the operation was 25.4 years (range, 15 to 60 years), and the mean duration of follow-up was 71.2 months (range, 12 to 185 months). When the preoperative values were compared with those at the latest follow-up, significant improvement was noted in terms of elevation (from a mean [and standard deviation] of 60.6° ± 17.2° to 123.7° ± 26.7°; p < 0.001), abduction (from 52.7° ± 15.8° to 98.8° ± 20.3°; p < 0.001), and qDASH scores (from 34.7 ± 11.4 to 13.3 ± 13.1; p < 0.001). The overall complication rate was 26.6%. There were 7 pulmonary complications (4 pneumothoraxes, 2 pleural effusions, and 1 major atelectasis), and 5 chest tube placements were required. Ten complications (including 3 rib fractures, 1 brachial plexus palsy, 2 cases of implant irritation, 2 nonunions, 1 delayed union, and 1 scapular fracture) were related to the scapular fixation, and 7 revision procedures were required. Scapulothoracic fusion was achieved in all patients but 1, who had a scapular fracture. Pulmonary function tests were performed for 19 patients, and no difference was observed between preoperative and postoperative results. CONCLUSIONS: Scapulothoracic arthrodesis with use of multifilament cables is a successful surgical technique with high fusion rates and low morbidity. Pulmonary complications are common but resolve with careful attention. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

The effect of intravenous tranexamic acid on visual clarity during arthroscopic rotator cuff repair: A randomized, double-blinded, placebo-controlled pilot study.

OBJECTIVE: The aim of this study was to determine the effect of intravenous (IV) tranexamic acid (TRX) use on visual clarity during arthroscopic rotator cuff repair. METHODS: This prospective, randomized, double-blinded, placebo-controlled study was conducted in patients scheduled for an arthroscopic rotator cuff repair. In total, 60 patients were randomly distributed into two groups: control (28 patients: 11 male, 17 female; mean age=53 years, age range=19-65) and TRX (32 patients: 15 male, 17 female; mean age=50, age range=18-69). In the TRX group, the arthroscopy was performed through the bolus IV administration of 10 mg/kg TRX in 100 ml isotonic saline solution. In the control group, the arthroscopy was performed through the bolus IV administration of 100 ml isotonic saline solution. In both the groups, the IV administration was carried out after the induction of anesthesia. At the end of each procedure, the surgeon rated the visual clarity on a scale from 1 to 10. In addition, operation time (minutes), irrigation amount used in operation (lt), and the need of pressure increase because of bleeding were recorded. RESULTS: No adverse effects were seen during the study period. Visual clarity in TRX group was significantly better than the control group (the mean visual clarity scores=8.1/10 (range=7-10) vs 7/10 (range=5-9); p=0.018). The amount of solution was significantly less in the TRX group (10.2 lt (range=3.5-21)) than in the control group (15.8 lt (range=5.8-27); p=0.007, post-hoc power=95.7%), although the operation time was slightly longer in the TRX group (106 minutes (range=50-210)) than in the control group (99 minutes (range=45-165); p=0.24). Moreover, the need for the increase in pressure owing to bleeding was found significantly less in the TRX group (5.8 times (range=(0-9)) than in the control group (9.6 times (range=0-13); p=0.04, post-hoc power=94.5%). CONCLUSION: Preoperative IV TRX administration seems to be effective in improving visual clarity and reducing the need for high pressure and the amount of irrigation fluid during the arthroscopic rotator cuff repair.

Scapulothoracic arthrodesis in facioscapulohumeral dystrophy with multifilament cable.

UNLABELLED: Patients with facioscapulohumeral dystrophy (FSHD) are affected mostly by impaired shoulder function. Scapulothoracic arthrodesis was introduced to improve shoulder function. We evaluated the outcomes of scapulothoracic arthrodesis using multifilament cables, performed on 13 patients with FSHD (18 shoulders). There were eight males and five females (mean age, 29 years; range, 20-50 years). Outcome criteria were active shoulder forward flexion and abduction, the Disabilities of the Arm, Shoulder, and Hand (DASH) score, respiratory function tests, and a new shoulder function score. Patients were followed for a minimum of 24 months (average, 35.5 months; range, 24-87 months). Solid fusion was obtained in all shoulders (two after revision); active abduction range increased from 47.2 degrees +/- 11.6 degrees to 102.2 degrees +/- 10.0 degrees (mean +/- standard deviation) and anterior flexion range from 55.6 degrees +/- 16.1 degrees to 126.1 degrees +/- 20.9 degrees . The DASH score decreased from 33.6 +/- 8.9 points preoperatively to 11.6 +/- 8.0 points postoperatively. Shoulder function score increased from 15.9 +/- 2.4 points to 22.2 +/- 1.3 points. Scapulothoracic arthrodesis provides satisfactory function in patients with FSHD. Our data suggest use of multifilament cables for fixation is a reasonable option with an acceptable complication rate. LEVEL OF EVIDENCE: Level IV, case series.

[Anconeus arthroplasty: a salvage procedure in recurrent heterotopic ossification]. / Ankoneus artroplastisi: Tekrarlayan heterotopik ossifikasyonda kurtarici bir girisim.

Anconeus interpositional arthroplasty has been used in the treatment of radiocapitellar and radioulnar joint problems occurring after trauma. We performed anconeus interposition arthroplasty in a 31-year-old male patient who developed heterotopic ossification (HTO) in the elbow following surgical treatment of an isolated radial neck fracture. Treatment with implant removal and excision of the radial head resulted in recurrent HTO and a stiff elbow. The patient underwent excision of the heterotrophic new bone and mobilization of the proximal radius. The anconeus muscle was mobilized and interposed between the proximal radius and ulna. Sixteen months after the operation, forearm rotation, elbow flexion and extension increased by 80 degrees , 45 degrees , and 60 degrees , respectively. Control X-rays showed maintenance of the radiohumeral gap without any signs of HTO.

[Functional results of the parallel-plate technique for complex distal humerus fractures]. / Paralel plak teknigi ile tedavi edilen kompleks humerus distal uç kiriklarinda fonksiyonel sonuçlar.

OBJECTIVES: We evaluated functional results of patients treated with open reduction and internal fixation with the parallel-plate technique for complex distal humerus fractures. METHODS: Twenty-one patients (14 males, 7 females; mean age 47 years; range 16 to 85) underwent open reduction with olecranon osteotomy and internal fixation with the parallel-plate technique for distal humerus fractures accompanied by highly intra-articular or metaphyseal comminution (n=10), intra-articular comminution and osteoporosis (n=7), and intra-articular and metaphyseal comminution with bone loss (n=4). According to the AO classification, there were 12 C3, six C2, and three C1 type fractures. Eight patients had open fractures. The mean time to surgery was six days (range 1 to 17 days). Functional results were evaluated using the Mayo elbow performance score, Jupiter elbow score, and DASH (Disabilities of the Arm, Shoulder and Hand) score. The mean follow-up was 28 months (range 12 to 48 months). RESULTS: The mean total range of motion was 90.2+/-31.1 degrees, flexion was 118.1+/-17.4 degrees, and extension was 27.8+/-17.4 degrees. The mean Mayo elbow performance score and DASH score were 86.1+/-12.6 and 7.6+/-9.5, respectively. According to the Jupiter elbow scores, the results were excellent in seven patients, good in 11 patients, moderate in two patients, and poor in one patient. Radiographically, solid union was achieved in all the patients. Heterotopic ossification of varying degrees was seen in seven patients, two of whom underwent resection of heterotopic ossification due to severe limitation of movement. Debridement was performed in one patient due to the development of deep infection. Chondrolysis of the elbow occurred in one patient. Patients with open fractures had significantly lower range of motion than those with closed fractures (p<0.05), but the Mayo elbow performance score and DASH score did not differ significantly in this respect (p>0.05). CONCLUSION: Functional results are satisfactory in distal humerus fractures treated with stable osteosynthesis and parallel-plate technique that allow early active motion.

[The effect of resistance-related proteins on the prognosis and survival of patients with osteosarcoma: an immunohistochemical analysis]. / Osteosarkomlu hastalarda dirençle iliskili proteinlerin prognoz ve sagkalim üzerine etkisi: Immünhistokimyasal analiz.

OBJECTIVES: Despite the developments in chemotherapy protocols, improvement in the survival rates of osteosarcoma has been limited. We evaluated the effect of certain prognosis-related proteins on survival of patients with osteosarcoma. METHODS: Data from 45 patients (24 males, 21 females) who were treated and followed-up for osteosarcoma were reviewed. Following neoadjuvant chemotherapy, 41 patients underwent extremity saving surgery, and four patients underwent amputation. The most frequent localization was the lower end of the femur (n=23, 51.1%), followed by the upper end of the tibia (n=10, 22.2%). Three patients had metastasis on admission. Surgical resection samples were retrieved from the pathology archive and analyzed immunohistochemically for the expression of p-glycoprotein p170, p53, heat-shock protein 27 (HSP27), HSP90, and nm23. The effect of these proteins on prognosis and survival was assessed with survival analysis using the Kaplan-Meier method. The mean follow-up was 49.7 months (range 6 to 185 months). RESULTS: Three patients with metastasis on admission died within five years due to pulmonary metastasis. New metastases developed in 29 patients. Total 5-year and 10-year survival rates were 60% and 43%, respectively. The corresponding disease-free survival rates were 41% and 24%. Five-year survival was 29% in patients who developed metastasis. Among clinical factors, survival was influenced only by the presence of metastasis on admission (p=0.044). Five-year and 10-year survival rates were significantly different between patients with and without p53 positivity (p=0.04), while the other proteins were not significantly associated with survival. CONCLUSION: Our data suggest that p53 may be used as a prognostic marker in osteosarcoma due to its significant association with survival.
