In the Treatment of Lateral Epicondylitis by Percutaneous Perforation, Injectables Have No Added Value.

BACKGROUND: No single injection therapy has been proven to be superior in the treatment of lateral epicondylitis. In most studies, the injection technique is not standardized, which makes it challenging to compare outcomes. QUESTIONS/PURPOSES: (1) Does injection with autologous blood, dextrose, or needle perforation only at the extensor carpi radialis brevis tendon origin produce better VAS pain scores during provocation testing at 5 months of follow-up? (2) Which percutaneous technique resulted in better secondary outcome measures: VAS during rest and activity, VAS during maximum grip, Oxford elbow score (OES), QuickDASH, Patient-related Tennis Elbow Evaluation (PRTEE), or EuroQol-5D (EQ-5D)? METHODS: In this multicenter, randomized controlled trial performed from November 2015 to January 2020, 166 patients with lateral epicondylitis were included and assigned to one of the three treatment groups: autologous blood, dextrose, or perforation only. Complete follow-up data were available for the primary outcome measures at the 5-month follow-up interval for 77% (127 of 166) of patients. Injections of the extensor carpi radialis brevis tendon were conducted in an accurate and standardized way. The three groups did not differ in terms of key variables such as age, gender, duration of symptoms, smoking habits, pain medication, and physiotherapy use. Data were collected at baseline and 8 weeks, 5 months, and 1 year after treatment and compared among the groups. The primary endpoint was the VAS pain score with provocation at 5 months. Our secondary study outcomes were VAS pain scores during rest, after activity, and after maximum grip strength; functional recovery; and quality of life. Therefore, we report the VAS pain score (0 to 100, with higher scores representing more-severe pain, minimum clinically important difference [MCID] 10), OES (0 to 48, with higher scores representing more satisfactory joint function, MCID 10), QuickDASH (0 to 100, with higher scores representing more severe disability, MCID 5.3), PRTEE (0 to 100, with higher scores representing more pain or more disability, MCID 20), EQ-5D/QALY (EQ-5D sumscore 0 to 1, with the maximum score of 1 representing the best health state, MCID 0.04), and EQ-5D VAS (0 to 100, with higher scores representing the best health status, MCID 8). For analysis, one-way analysis of variance and a linear mixed-model analysis were used. The analyses were performed according to the intention-to-treat principle. Four patients from the perforation group opted to crossover to autologous blood after 5 months. RESULTS: No injection therapy proved to be superior to any other in terms of VAS pain scores during the provocation test at 5 months of follow-up (VAS for perforation: 25 ± 31; autologous blood: 26 ± 27; dextrose: 29 ± 32; p = 0.35). For the secondary outcomes, only a clinically important difference was found for the QuickDASH score. Both the perforation-only group (-8 [98% CI -4 to -12]) and autologous blood (-7 points [98% CI -3 to -11]) had improved QuickDASH scores over time compared with the dextrose group (MCID 5.3; p < 0.01). For the other outcomes, no clinically important differences were found. CONCLUSION: There is no benefit to injectable autologous blood and dextrose over perforation alone to treat lateral epicondylitis, and they are therefore not indicated for this condition. LEVEL OF EVIDENCE: Level I, therapeutic study.

Smaller radioulnar window is associated with a distal biceps tendon rupture in patients with limited forearm rotation: a 3-dimensional computed tomography comparison study of proximal impingement caused by radial tuberosity hypertrophy-a single-center case series.

BACKGROUND: It has been suggested that hypertrophy of the radial tuberosity may result in impingement leading to either a lesion of the distal biceps tendon or rotational impairment. Two previous studies on hypertrophy of the radial tuberosity had contradictory results and did not examine the distance between the radius and ulna: the radioulnar window. Therefore, this comparative cohort study aimed to investigate the radioulnar window in healthy subjects and compare it with that in subjects with either nontraumatic-onset rotational impairment of the forearm or nontraumatic-onset distal biceps tendon ruptures with rotational impairment of the forearm by use of dynamic 3-dimensional computed tomography measurements to attain a comprehensive understanding of the underlying etiology of distal biceps tendon ruptures. We hypothesized that a smaller radioulnar window would increase the risk of having a nontraumatic-onset distal biceps tendon rupture and/or rotational impairment compared with healthy individuals. METHODS: This study measured the distance between the radius and ulna at the level of the radial tuberosity using entire-forearm computed tomography scans of 15 patients at the Amphia Hospital between 2019 and 2022. Measurements of healthy subjects were compared with those of subjects who had nontraumatic-onset rotational impairment of the forearm and subjects who had a nontraumatic-onset distal biceps tendon rupture with rotational impairment of the forearm. The Wilcoxon signed rank test was used for individual comparisons, and the Mann-Whitney U test was used for group comparisons. RESULTS: A significant difference was found between the radioulnar window in the forearms of the subjects with a distal biceps tendon rupture (mean, 1.6 mm; standard deviation 0.2 mm) and the radioulnar window in the forearms of the healthy subjects (mean, 4.8 mm; standard deviation, 1.4 mm; P = .018). A trend toward smaller radioulnar windows in the rotational impairment groups was also observed, although it was not significant (P > .05). CONCLUSIONS: The radioulnar window in the forearms of the subjects with a distal biceps tendon rupture with rotational impairment was significantly smaller than that in the forearms of the healthy subjects. Therefore, patients with a smaller radioulnar window have a higher risk of rupturing the distal biceps tendon. Nontraumatic-onset rotational impairment of the forearm may also be caused by a similar mechanism. Future studies are needed to further evaluate these findings.

Silicone radial head prostheses: the clinical course and treatment of failure-a case series.

INTRODUCTION: Silicone radial head prostheses (SRHP) have a reputation of acceptable initial function but failure in the medium to long term as a result of the disintegration of the silicone material. Damaged SRHP can result in a silicone-induced synovitis and destruction of the joint. Early removal of damaged SRHP may prevent joint destruction. Literature is scarce; there are no studies describing early symptoms associated with clinical failure of SRHP and very few studies on appropriate treatment of destructed SRHP. The aim of this study was to describe the clinical course of failing SRHP and to provide practical guidance for treatment. METHODS: Fifteen consecutive cases of failed SRHP, operated between 2005 and 2020, were retrospectively reviewed, using patient logs, radiographic results, and a questionnaire. Relevant data concerning pre- and postoperative complaints, function, and surgical details were gathered. Using the questionnaire, retrospective and current patient reported outcomes including Single Assessment Numeric Evaluation (SANE) scores, pain, instability, and range of motion were analyzed. RESULTS: The average time between implantation of the SRHP until outpatient presentation was 16 years. The average recalled SANE score before start of complaints was 8.6 out of 10 points. In 4 patients, the onset of complaints was preceded by a trauma. Five patients had symptoms for more than a year, and 9 patients for several months. Progressive pain in the elbow and/or wrist and mechanical symptoms were early and prominent symptoms of failure. Clinical signs of synovitis were frequently present. The majority of patients had a slow but progressive onset of complaints over several months before presentation. Twelve of 15 cases of failed SRHP were surgically treated. Fragmentation of the implant, osteoarthritis, and synovitis were found in all surgically treated cases. Both surgical removal and synovectomy alone, and revision to a new radial head prosthesis resulted in good medium-term outcomes with a mean SANE score of 7.3 points at 8.4 years of follow-up. Postoperative extension lags and mild instability were frequently mentioned as a reason for reimplantation of a metallic radial head implant and removal of the radial head alone, respectively. CONCLUSION: Both patients and physicians should be aware of early symptoms of a failing SRHP. Adequate recognition, radiographic evaluation, and early intervention may favor outcomes of failing SRHP. Surgical removal is easy to perform. In selected cases, revision of the radial head prosthesis may be considered. Both of these treatment strategies resulted in satisfying outcomes.

Three weeks of indomethacin is not superior to 1 week of meloxicam as prophylaxis for heterotopic ossifications after distal biceps tendon repair with a single-incision technique.

BACKGROUND: The aim of this study was to assess the efficacy of 3 weeks of indomethacin, a nonselective nonsteroidal anti-inflammatory drug, in comparison to 1 week of meloxicam as prophylaxis for heterotopic ossifications (HOs) after distal biceps tendon repair. METHODS: A single-center retrospective study was performed on 78 patients undergoing distal biceps tendon repair between 2008 and 2019. From 2008 to 2016, patients received meloxicam 15 mg daily for the period of 1 week as usual care. From 2016 onward, the standard protocol was changed to indomethacin 25 mg 3 times daily for 3 weeks. All patients underwent a single-incision repair with a cortical button technique. The postoperative rehabilitation protocol was similar for all patients. The postoperative radiographs at 8-week follow-up were assessed blindly by 7 independent assessors. If HOs were present, it was classified according to the Ilahi-Gabel classification for size and according to the Gärtner-Heyer classification for density. Statistical analysis was performed to analyze the difference in HO between the patients who were treated with indomethacin and with meloxicam. RESULTS: Seventy-eight patients, with a mean age of 48.8 years (range 30-72) were included. The mean follow-up after surgery was 12 months (range 2-45). Indomethacin (21 days, 25 mg 3 times per day) was prescribed to 26 (33%) patients. The 52 other patients (67%) were prescribed meloxicam 15 mg daily for 7 days. HOs were seen in 19 patients 8 weeks postoperatively. Five of 26 patients treated with indomethacin developed HO, and 14 of 52 patients treated with meloxicam developed HO (P = .5). Two patients had symptomatic HO with minor restrictions in movement; neither patient was treated with indomethacin. Significantly more HOs were seen in patients with a longer time from injury to surgery (P = .01) The intraclass correlation score for reliability between assessors for HO scoring on postoperative radiographs was good to excellent for both classifications. CONCLUSION: In this study, HOs were seen in 24% of postoperative radiographs. Three weeks of indomethacin was not superior to meloxicam for 1 week for the prevention of HO after single-incision distal biceps tendon repair.

Greater radial tuberosity size is associated with distal biceps tendon rupture: a quantitative 3-D CT case-control study.

PURPOSE: During pronation, the distal biceps tendon and radial tuberosity internally rotate into the radioulnar space, reducing the linear distance between the radius and ulna by approximately 50%. This leaves a small space for the distal biceps tendon to move in and could possibly cause mechanical impingement or rubbing of the distal biceps tendon. Hypertrophy of the radial tuberosity potentially increases the risk of mechanical impingement of the distal biceps tendon. The purpose of our study was to determine if radial tuberosity size is associated with rupturing of the distal biceps tendon. METHODS: Nine patients with a distal biceps tendon rupture who underwent CT were matched 1:2 to controls without distal biceps pathology. A quantitative 3-dimensional CT technique was used to calculate the following radial tuberosity characteristics: 1) volume in mm3, 2) surface area in mm2, 3) maximum height in mm and 4) location (distance in mm from the articular surface of the radial head). RESULTS: Analysis of the 3-dimensional radial tuberosity CT-models showed larger radial tuberosity volume and maximum height in the distal biceps tendon rupture group compared to the control group. Mean radial tuberosity volume in the rupture-group was 705 mm3 (SD: 222 mm3) compared to 541 mm3 (SD: 184 mm3) in the control group (p = 0.033). Mean radial tuberosity maximum height in the rupture-group was 4.6 mm (SD: 0.9 mm) compared to 3.7 mm (SD: 1.1 mm) in the control group, respectively (p = 0.011). There was no statistically significant difference in radial tuberosity surface area (ns) and radial tuberosity location (ns). CONCLUSION: Radial tuberosity volume and maximum height were significantly greater in patients with distal biceps tendon ruptures compared to matched controls without distal biceps tendon pathology. This supports the theory that hypertrophy of the radial tuberosity plays a role in developing distal biceps tendon pathology. LEVEL OF EVIDENCE: Level III.

Surgical approaches for total elbow arthroplasties using data from the Dutch Arthroplasty Register.

BACKGROUND: Total elbow arthroplasty (TEA) is a relatively infrequently performed procedure. Therefore, nationwide databases help to provide more insight into factors that might influence implant survival, for example, the surgical approach used. Using data from the Dutch Arthroplasty Register, we aimed to reveal whether high-volume centers use different approaches than low-volume centers and whether the approach is implant specific. METHODS: Using data from 2014 to 2017, we compared the surgical approaches used for high- vs. low-volume centers, as well as for the 2 most frequently used types of TEA, by use of χ2 tests. RESULTS: We analyzed 276 procedures. In 2016 and 2017, when posterior approaches were further specified, the triceps-on approach was used most frequently in the high-volume center (27 of 42 procedures, 64%) and the triceps-flap approach was used most often in the low-volume centers (48 of 84 procedures, 57%) (P < .001). For the 2 most frequently used types of TEA, the Coonrad-Morrey and Latitude EV arthroplasties, the surgical approaches did not differ. When the high-volume center was compared with the low-volume centers, implant choice differed, with the Coonrad-Morrey arthroplasty being most often used in the high-volume center and the Latitude EV arthroplasty, in the low-volume centers. CONCLUSION: The posterior triceps-flap approach was the most frequently used surgical approach in primary TEA in the Netherlands, yet the triceps-on approach was used more often in the high-volume center. The surgical approaches did not differ between the 2 most frequently used types of TEA in the Netherlands.

Radiocapitellar prosthetic arthroplasty: short-term to midterm results of 19 elbows.

BACKGROUND: Few studies have discussed the short-term results of radiocapitellar (RC) prosthetic arthroplasty (PA). In this study, we assessed the short-term to midterm functional and radiographic results of elbows after RC PA. Our secondary aim was to assess the survival of the RC PA. METHODS: We included 19 elbows in 18 patients with a mean follow-up of 35 months (range, 12-88 months). Patients were examined for instability and range of motion and were assessed using Mayo Elbow Performance Index and Oxford Elbow Score at any subsequent visits. RC PA was the primary treatment in 16 elbows, and 3 were revision radial head arthroplasty with concomitant capitellar resurfacing. RESULTS: Range of motion, pain, and functional scores improved significantly from the preoperative to the final follow-up visit. Categoric grouping of the final Mayo Elbow Performance Index outcome scores showed 9 excellent, 5 good, 3 fair, 0 poor, and 2 missing data. However, stability of the elbow remained unchanged. There was no pain in 11 patients, mild pain in 5, and moderate pain in 3. Radiographic assessment showed no significant progress in ulnohumeral arthritis, although 3 elbows showed osteoarthritis progression to a higher grade. There were no major complications, including infection, revision, disassembly of the components, or conversion to total elbow arthroplasty. Survival of the RC PA was 100%. CONCLUSION: Elbow arthritis seems to become stationary after RC PA. Symptomatic RC osteoarthritis would probably benefit from RC PA regardless of the etiology.

Manipulation under anesthesia versus physiotherapy treatment in stage two of a frozen shoulder: a study protocol for a randomized controlled trial.

BACKGROUND: There is no consensus about the optimal treatment strategy for frozen shoulders (FS). Conservative treatment consisting of intra-articular corticosteroid infiltrations and physiotherapy are considered appropriate for most patients. However, with a conservative strategy, patients experience a prolonged rehabilitation period with a considerable amount of pain and disabilities in daily life. Also, at long term, a residual amount of pain and restriction of range of motion is frequently reported. Manipulation under anesthesia is a short and relative simple procedure with the potential to rapidly reduce symptoms and restore the range of motion. The objective of this trial is to evaluate the effectiveness of MUA followed by a PT program compared to a PT program alone, in the treatment of patients with a stage two FS. We hypothesize that the course of the disease can be shortened with MUA with a quicker functional recovery. METHODS: This is a prospective, single center, randomized controlled trial. Eligible patients will be allocated to either the manipulation (MUA) group or the physiotherapy alone (PT) group. In the MUA group manipulation will be performed under interscalene block, directly followed by an intensive physiotherapy treatment protocol, with the goal to maintain the obtained range of motion. Patients allocated to the PT group are given advice and education and receive a written protocol to hand out to their physical therapist based on the recent guideline of the Dutch Shoulder Network for the treatment of frozen shoulders. Descriptive statistics will be used to describe the sample size, patients demographics, presence of diabetes mellitus, range of motion, duration of symptoms till randomization and will be presented for each treatment group. The SPADI is used as primary functional outcome parameter. Secondary outcome parameters are; OSS, NPRS, EQ-5D 3-L, passive range of motion, WORQ-UP, duration of symptoms, usage of analgesics and adverse events. A sample size of 41 subjects in each group was calculated. Follow up is planned after 1,3 and 12 months. The length of physiotherapy treatment in both groups is variable, depending on individual progression. Differences between groups in outcome parameters will be analysed using the linear mixed modelling and the restricted maximum likelihood ratio technique for estimating the model parameters. DISCUSSION: Successful completion of this trial will provide evidence on the best treatment strategy for patients with a stage two frozen shoulder. The results of this study can lead to a better understanding for the role of manipulation in the treatment of frozen shoulders. TRIAL REGISTRATION: This trial is registered in the Dutch Trial Register under the number NTR6182 on the 20th of February 2017.

Continuous passive motion and physical therapy (CPM) versus physical therapy (PT) versus delayed physical therapy (DPT) after surgical release for elbow contractures; a study protocol for a prospective randomized controlled trial.

BACKGROUND: The elbow is prone to stiffness after trauma. To regain functional elbow motion several conservative- and surgical treatment options are available. Conservative treatment includes physical therapy, intra-articular injections with corticosteroids and a static progressive or dynamic splinting program. If conservative treatment fails, an operative release of the posttraumatic stiff elbow is often performed. The best Evidence-Based rehabilitation protocol for patients after an operative release is unknown to date and differs per surgeon, hospital and country. Options include early- or delayed motion supervised by a physical therapist, immediate continuous passive motion (CPM), (night) splinting and a static progressive or dynamic splinting program. METHODS/DESIGN: The SET-Study (Stiff Elbow Trial) is a single-centre, prospective, randomized controlled trial. The primary objective of this study is to compare the active Range of Motion (ROM) (flexion arc and rotational arc) twelve months after surgery between three groups. The first group will receive in-hospital CPM in combination with early motion Physical Therapy (PT) supervised by a physical therapist, the second group will receive only in-hospital early motion PT supervised by a physical therapist and the third group will receive outpatient supervised PT from postoperative day seven till ten. Secondary outcome measures will be Patient Reported Outcome Measures (PROMs) including the Mayo Elbow Performance Score (MEPS), the Oxford Elbow Score (OES), the quick Disabilities of Arm, Shoulder and Hand (qDASH) score, Visual Analogue pain Scale in rest and activity (VAS), Pain Catastrophizing Scale (PCS), the Short Form (SF)-36, the Centre for Epidemiological Studies Depression Scale Revised (CESD-R) and the Work Rehabilitation Questionnaire (WORQ) for the upper limb. DISCUSSION: A successful completion of this trial will provide evidence on the best rehabilitation protocol in order to (re)gain optimal motion after surgical release of the stiff elbow. TRIAL REGISTRATION: The trial is registered at the Dutch Trial Register: NTR6067 , 31-8-2016.

Clinical and radiographic outcome of revision surgery of total elbow prosthesis: midterm results in 19 cases.

BACKGROUND: The aim of this study is to report on the midterm outcomes and complications of revision surgery of total elbow arthroplasty. METHODS: All patients who had undergone total elbow arthroplasty revision surgery between 2009 and 2014 with semiconstrained total elbow prostheses were prospectively enrolled in the study. Records were reviewed for demographic data; baseline measurements; and several follow-up assessments including the Mayo Elbow Performance Score (MEPS), visual analog scale (VAS) score for pain, Oxford Elbow Score, range of motion, satisfaction, and radiographs. RESULTS: A total of 19 revision arthroplasties were included. At a mean follow-up of 57 months, there had been 1 rerevision and 2 removals. One patient was excluded from follow-up because of confounding comorbidity. At last follow-up, MEPS values and VAS pain scores both improved (P < .01). The rate of combined good and excellent results on the MEPS was 53%. The mean VAS scores for pain at rest and with activity were 2 and 4, respectively. Fair results for the Oxford Elbow Score were reported, with a mean score of 28 points. Range of motion improved to an average flexion-extension arc of 108° (P < .01), and the pronation-supination arc improved to an average of 123° (P < .01). All elbows were stable at last follow-up (P < .01). Radiographs showed nonprogressive osteolysis around the prosthesis in 3 cases (19%) and suspicion of loosening in 1 (6%). In 11 patients postoperative complications occurred. Of 15 patients, 13 (87%) were satisfied with the result of the revision procedure. CONCLUSION: Revision of total elbow prostheses leads to satisfactory results, less pain, and better elbow function. This procedure is related to a relatively high complication rate.

Clinical and radiographic outcome of revision surgery of radial head prostheses: midterm results in 16 patients.

BACKGROUND: Little is known about revision surgery of radial head arthroplasty. The aim of this study was to report on the clinical and radiographic outcome of revision arthroplasty of the elbow with a bipolar metallic radial head prosthesis. METHODS: Between 2006 and 2013, we used either a press-fit or cemented RHS bipolar radial head prosthesis for revision surgery of radial head arthroplasty in 16 patients. Patients were prospectively enrolled in the study. Differences in outcome parameters before and after revision surgery were compared. RESULTS: At a mean follow-up of 75 months (range, 36-116 months), none of the revised radial head prostheses needed a second revision. None of the stems showed radiographic signs of loosening. In 1 patient the head was dissociated from the prosthesis. The average flexion-extension arc was 127° (range, 105°-140°), and the average pronation-supination arc was 138° (range, 90°-160°). Stability scores improved after revision surgery, resulting in 13 stable elbows (P = .01). In 8 patients the Oxford Elbow Score was between 37 and 48 points. The percentage of patients with either good or excellent results according to the Mayo Elbow Performance Score was 63%. The mean score on the EQ-5D (EuroQol Five Dimensions) was 80 (range, 63-100), and the visual analog scale scores both for pain at rest and for pain with activity improved to 3 (range, 0-9) and 4 (range, 0-9), respectively (P < .001). All but 1 patient was satisfied with the results of the revision procedure. CONCLUSION: The clinical and radiographic outcomes of revision surgery of a radial head prostheses are favorable.

Why does total elbow arthroplasty fail today? A systematic review of recent literature.

BACKGROUND: Total elbow arthroplasty is a relatively uncommon type of arthroplasty, which has undergone several design changes in the past four decades. However, research on improvement requires knowledge of failure mechanisms that can be addressed. Therefore, we conducted a systematic review on modes of failure of total elbow arthroplasty. METHODS: We conducted searches on PubMed/Medline, Embase and Cochrane databases to identify studies describing modes of failure of primary total elbow arthroplasties. The results were coupled per type of total elbow arthroplasty and individual arthroplasty models. RESULTS: A total of 70 articles were included in this systematic review. 9308 individual total elbow arthroplasties were identified with 1253 revisions (13.5%). Aseptic loosening was the most prevalent reason for revision (38%), followed by deep infection (19%) and periprosthetic fractures (12%). CONCLUSION: Revision rates have been found similar to a systematic review published in 2003. The revision percentage of total elbow arthroplasty for rheumatoid arthritis is significantly higher than for trauma and post-traumatic osteoarthritis. Aseptic loosening was seen less in linked implants. Infections and periprosthetic fractures did not differ between linkage design groups. Aseptic loosening remains the most frequent cause for revision of primary total elbow arthroplasty. Therefore, more research on the occurrence, progression and risk factors of aseptic loosening should be performed and lead to higher implant survival.

Pre-operative templating in total elbow arthroplasty: not useful.

PURPOSE: Total elbow arthroplasty (TEA) is a definitive surgical procedure for treating rheumatoid arthritis and (posttraumatic) osteoarthritis of the elbow and is also useful in comminuted elbow fractures. Pre-operative digital templating may theoretically improve the surgical implantation of TEA, but reliability and predictive values of templating are unknown. The aim of this study was to determine the intra- and inter-observer reliability and the validity of pre-operative digital templating for TEA. MATERIALS AND METHODS: All pre-operative plain anterior-posterior and lateral calibrated elbow radiographs from patients who underwent TEA in our center from 2008 to June 2014 were reviewed. Two independent assessors templated implant sizes using digital overlays twice. Intra- and inter-observer reliability were evaluated with Cohen's kappa. Two experienced elbow surgeons reviewed post-operative radiographs for evaluation. The predictive value of templating was the percentage of the correctly templated sizes, with the optimal implant size as the reference standard. RESULTS: Twenty-one cases were included. Intra-observer reliability was substantial to almost perfect (κ = 0.61 and κ = 0.90) for humeral implants, moderate to substantial (κ = 0.54 and κ = 0.73) for ulnar implants. Inter-observer reliability was substantial (κ = 0.67) for humeral implants and moderate (κ = 0.60) for ulnar implants. The predictive value was 53 % for both implants. CONCLUSIONS: Pre-operative digital templating for TEA is a reliable method to plan implant sizes. However, the predictive value is low.

Biceps muscle fatty infiltration and atrophy. A midterm review after arthroscopic tenotomy of the long head of the biceps.

PURPOSE: Pathology of the long head of the biceps (LHB) tendon is commonly treated by tenotomy. High levels of clinical function and patient satisfaction are reported in the short-term. The purpose of this study was to investigate the midterm effects of tenotomy on biceps fatty infiltration and atrophy in active working-age male patients. METHODS: Twenty-five men (mean age, 57 years) were evaluated at a mean follow-up of 6.7 years after tenotomy. Bilateral magnetic resonance imaging (MRI) was performed, and fatty infiltration of the biceps was assessed relative to the ipsilateral triceps. Seventeen participants had an intact contralateral LHB tendon. To assess atrophy, anterior muscle compartment volume was measured by serial cross-sectional area measurements on MRI. The tenotomized side was then compared to the healthy side in these 17 participants. Clinical scores were obtained using the QuickDASH and Oxford Elbow Score, and the occurrence of a Popeye sign and residual pain were recorded. RESULTS: Good clinical function was maintained at a mean follow-up time of 6.7 years (range, 4 to 10 years) (QuickDASH score of 7.1; standard error [SE], 1.8) and Oxford Elbow Score of 97.9 [SE 1.2]). Eleven of the 25 participants had a Popeye deformity. Four participants showed signs of fatty infiltration, and all were minor (grade 1). The mean decrease in total volume of the anterior musculature was 3.6%. In participants without a Popeye deformity, it was 3.3%, whereas it was 4.1% in participants with a Popeye sign (P = .8). CONCLUSIONS: In the midterm, LHB tenotomy in active men of working age does not result in fatty degeneration or substantial atrophy in the anterior musculature of the arm. Clinical function remains good. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Improved range of motion after manipulation under anesthesia versus physiotherapy for stage two frozen shoulder: a randomized controlled trial.

Background: Frozen shoulder (FS) is a common cause of shoulder pain and stiffness. Conservative treatment is sufficient for the majority of patients with long-term recovery of shoulder function. Manipulation under anesthesia (MUA) is known as a well-established treatment option if conservative treatment fails. It is unknown whether MUA does indeed shorten the duration of symptoms or leads to a superior outcome compared to conservative treatment. The objective of the current trial is to evaluate the effectiveness of MUA followed by a physiotherapy (PT) program compared to a PT program alone in patients with stage 2 FS. Methods: A prospective, single-center randomized controlled trial was performed. Patients between 18 and 70 years old with stage 2 FS were deemed eligible if an initial course of conservative treatment consisting of PT and intra-articular corticosteroid infiltration was considered unsatisfactory. Patients were randomized, and data was collected with an online data management platform (CASTOR). MUA was performed by a single surgeon under interscalene block, and intensive PT treatment protocol was started within 4 hours after MUA. In the PT group, patients were referred to instructed physiotherapist, and treatment was guided by tissue irritability. The primary outcome was the Shoulder Pain and Disability Index (SPADI) score. Secondary outcomes were pain, range of motion (ROM), Oxford Shoulder Score, quality of life, and ability to work. Results: In total, 82 patients were included, 42 in the PT group and 40 in the MUA group. There was a significant improvement in SPADI, Oxford Shoulder Score, pain, ROM, and quality of life in both groups at 1-year follow-up. SPADI scores at three months were significantly improved in favor of MUA. MUA showed a significantly bigger increase in anteflexion and abduction compared to PT at all points of follow-up. No significant differences between both groups were found for all other parameters. No fractures, dislocations, or brachial plexus injuries occurred in this trial. Conclusion: MUA in stage 2 FS can be considered safe and results in a faster recovery of ROM and improved functional outcome, measured with SPADI scores, compared to PT alone in the short term. After 1 year, except for slightly better ROM scores for MUA, the result of MUA is equal to PT.

Elbow-specific clinical rating systems: extent of established validity, reliability, and responsiveness.

BACKGROUND: The modern standard of evaluating treatment results includes the use of rating systems. Elbow-specific rating systems are frequently used in studies aiming at elbow-specific pathology. However, proper validation studies seem to be relatively sparse. In addition, these scoring systems might not always be used for appropriate populations of interest. Both of these issues might give rise to invalid conclusions being reported in the literature. Our aim was to investigate the extent to which the available elbow-specific outcome measurement tools have been validated and the quality of the validation itself. We also aimed to provide characteristics of the populations used for validation of these scales to enable clinicians to use them appropriately. METHODS: A literature search identified 17 studies of 12 different elbow-specific scoring systems. These were assessed for validity, reliability, and responsiveness characteristics. The quality of these assessments was rated according to the Consensus Based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist criteria, a standardized and validated tool developed specifically for this purpose. RESULTS: Currently, the only elbow-specific rating system that is validated using high-quality methodology is the Oxford Elbow Score, a patient-administered outcome measure tool that has been validated on heterogeneous study populations. CONCLUSION: Other rating systems still have to be proven in the future to be as good as the Oxford Elbow Score for clinical or research purposes. Additional validation studies are needed.

Silicone radial head prostheses revisited: do they have a role in today's practice? A systematic review of literature on clinical outcomes.

BACKGROUND: Silicone radial head prostheses (SRHP) are considered obsolete due to reports of frequent failure and destructive silicone-induced synovitis. Considering the good outcomes of modern non-radial silicone joint implants, the extent of scientific evidence for this negative view is unclear. The aim of this research was to systematically analyze the clinical evidence on complications and outcomes of SRHP and how SRHP compare to both non-SRHP and silicone prostheses of other joints. METHODS: A systematic literature review was conducted through the Cochrane, PubMed, and Embase databases. RESULTS: Eight cohort studies were included, consisting of 142 patients and follow-up periods ranging from 23 months to 8 years. Average patient satisfaction was 86%, range of 71%-100%, and 58 complications were seen, but no cases of synovitis. These outcomes were in line with non-SRHP. Four case series with 11 cases of synovitis were found, all due to implant fractures years to decades after implantation. Six systematic reviews of currently used non-radial silicone joint implants showed excellent outcomes with low complication rates. CONCLUSIONS: Since SRHP have satisfactory clinical results and an acceptable complication rate when selecting a patient group in suitable condition for surgical indications, it is considered that SRHP can still be chosen as a potential surgical treatment method in current clinical practice.

Intraoperative arthroscopic classification tool for posterolateral elbow instability.

Background: Introducing and implementing an arthroscopic classification tool for posterolateral elbow instability. Methods: Thirty arthroscopies were performed on 30 patients, and all recordings were collected, blinded, and labeled. Three orthopedic surgeons reviewed and scored all 30 recordings three times with a period of at least seven days in between to analyze the intraobserver and interobserver reliability. The classification consisted of five different grades. Results: Indications for elbow arthroscopy included impingement (n = 7), osteochondritis dissecans (n = 5), pain (n = 7), osteoarthritis (n = 6), and other (n = 5). The kappa value for intrarater reliability was 0.71, indicating good reliability, while the kappa value for inter-rater reliability was 0.38 indicating fair reliability. Conclusion: This new classification is a tool for an arthroscopic assessment of PLRI and can be used as a standardized grading system for further research and communication between orthopedic surgeons. We demonstrated good intrarater reliability (k = 0.71) with fair inter-rater reliability (k = 0.38). However, further research is necessary to study the clinical significance.

Lateral Humeral Condyle Fractures in Pediatric Patients.

Lateral humeral condyle fractures are frequently seen in pediatric patients and have a high risk of unfavorable outcomes. A fall on the outstretched arm with supination of the forearm is the most common trauma mechanism. A physical examination combined with additional imaging will confirm the diagnosis. Several classifications have been described to categorize these fractures based on location and comminution. Treatment options depend on the severity of the fracture and consist of immobilization in a cast, closed reduction with percutaneous fixation, and open reduction with fixation. These fractures can lead to notable complications such as lateral condyle overgrowth, surgical site infection, pin tract infections, stiffness resulting in decreased range of motion, cubitus valgus deformities, 'fishtail' deformities, malunion, non-union, avascular necrosis, and premature epiphyseal fusion. Adequate follow-up is therefore warranted.

Implant survival of total elbow arthroplasty: analysis of 514 cases from the Dutch Arthroplasty Registry.

The aim of this study is to report the implant survival and factors associated with revision of total elbow arthroplasty (TEA) using data from the Dutch national registry. All TEAs recorded in the Dutch national registry between 2014 and 2020 were included. The Kaplan-Meier method was used for survival analysis, and a logistic regression model was used to assess the factors associated with revision. A total of 514 TEAs were included, of which 35 were revised. The five-year implant survival was 91%. Male sex, a higher BMI, and previous surgery to the same elbow showed a statistically significant association with revision (p < 0.036). Of the 35 revised implants, ten (29%) underwent a second revision. This study reports a five-year implant survival of TEA of 91%. Patient factors associated with revision are defined and can be used to optimize informed consent and shared decision-making. There was a high rate of secondary revisions.
