Aims. This study aimed to determine the minimal detectable change (MDC), minimal clinically important difference (MCID), and substantial clinical benefit (SCB) under distribution- and anchor-based methods for the Mayo Elbow Performance Index (MEPI) and range of movement (ROM) after open elbow arthrolysis (OEA). We also assessed the proportion of patients who achieved MCID and SCB; and identified the factors associated with achieving MCID. Methods. A cohort of 265 patients treated by OEA were included. The MEPI and ROM were evaluated at baseline and at two-year follow-up. Distribution-based MDC was calculated with confidence intervals (CIs) reflecting 80% (MDC 80), 90% (MDC 90), and 95% (MDC 95) certainty, and MCID with changes from baseline to follow-up. Anchor-based MCID (anchored to somewhat satisfied) and SCB (very satisfied) were calculated using a five-level Likert satisfaction scale. Multivariate logistic regression of factors affecting MCID achievement was performed. Results. The MDC increased substantially based on selected CIs (MDC 80, MDC 90, and MDC 95), ranging from 5.0 to 7.6 points for the MEPI, and from 8.2° to 12.5° for ROM. The MCID of the MEPI were 8.3 points under distribution-based and 12.2 points under anchor-based methods; distribution- and anchor-based MCID of ROM were 14.1° and 25.0°. The SCB of the MEPI and ROM were 17.3 points and 43.4°, respectively. The proportion of the patients who attained anchor-based MCID for the MEPI and ROM were 74.0% and 94.7%, respectively; furthermore, 64.2% and 86.8% attained SCB. Non-dominant arm (p = 0.022), higher preoperative MEPI rating (p < 0.001), and postoperative visual analogue scale pain score (p < 0.001) were independent predictors of not achieving MCID for the MEPI, while atraumatic causes (p = 0.040) and higher preoperative ROM (p = 0.005) were independent risk factors for ROM. Conclusion. In patients undergoing OEA, the MCID for the increased MEPI is 12.2 points and 25° increased ROM. The SCB is 17.3 points and 43.3°, respectively. Future studies using the MEPI and ROM to assess OEA outcomes should report not only statistical significance but also clinical importance. Cite this article: Bone Joint J 2021;103-B(2):366–372

Purpose. Evaluation of our experience on the treatment of comminuted, radial head fractures, and of the outcomes of pyrocarbon prosthetic replacement in such cases. Materials and Methods. We evaluated 47 cases of prosthetic replacement, performed from May 2003 to July 2008. There were 18 males and 29 females with an average follow-up of 48 months (12 to 60). The Hotchkiss classification was used to characterize the fractures. The indicators for the procedure were type III fractures in 27 cases, type IV fractures in 10 cases, comminuted radial head fractures (associated with disruption in medial collateral ligament) in 3 cases, Monteggia variant in 5 cases, and Essex Lopresti in 2 cases. Functional outcomes were assessed using the Mayo Elbow Performance Index and the Visual Analog Scales (VAS) of pain, joint motion, and stability. Results. The mean VAS score for elbow pain was 1 (0.5–2.1). Patients showed an average arch of motion from 6 degrees to 140, with 75 degrees of pronation, and 67 of supination. By the Mayo Elbow Performance Index, 42 patients had good to excellent results, 3 fair, and 2 poor. The complications that we have encountered were: implant dislocations (2 cases), elbow stiffness (1), implant dissociation (1), stem rupture (1), and transient PIN palsy (2 cases with complete recovery of nervous function at 5 and 8 weeks). There was no persistent instability, infection, synosthosis, severe degenerative changes, or impingement. Conclusion. The pyrocarbon implants are a good treatment option in complicated, radial head fractures, but the outcome depends on the severity of the initial fracture and the associated lesions. We have also encountered a tendency towards overestimating the prosthesis size, causing restriction of motion, impingement, overstuffing, or dislocation. For these results we are now using the non-modular prosthesis in our center, but further studies are required

Aim: As the shoulder and elbow joints share a common objective – spatial positioning of the hand – can the Modified Constant Score of shoulder function be applied to function at the elbow?. Method & Results: All patients with isolated elbow pathology over an eighteen-month period were assessed. Acute fractures and patients with shoulder and/or wrist pathology were excluded. Upper limb function was assessed using the Modified Constant Score and the Mayo Elbow Performance Index. A total of 48 patients with a variety of elbow pathologies were assessed. The mean patient age was 47.8 years, and 26 patients were male. The correlation between the two scoring systems was highly significant (correlation 0.91, t = < 0.001). Conclusion: The Modified Constant Score may be used as an assessment of both shoulder and elbow function

Background. The optimal treatment for symptomatic elbow osteoarthritis remains debatable especially in patients still involved in heavy manual work. The Outerbridge-Kashiwagi (OK) procedure has been used when simple measures fail. The aim of this study is to analyse the results of the OK procedure in patients with symptomatic osteoarthritis. Methods. Twenty-two patients were included in the study. The male:female ratio was 18:4. The mean age was 60 years with mean follow-up of 38 months (24–60 months). 17 were manual workers, 3 involved in sports activities and 2 non-manual workers. All patients were assessed using Mayo Elbow Performance Index Score system. Preoperative radiological assessment showed osteophytes around olecranon and coronoid process and joint space narrowing in radio-humeral articulationin all cases. Results. There was a significant improvement (p<0.05) in movement in the flexion-extension axis from 78.2° to 107.3°. There was a significant reduction in pain post-operatively (p<0.001). Mean MEPI score improved from 50 to 87.4 post surgery which was significant (p<0.05). One patient had ulnar nerve palsy which resolved in six months with conservative management. The results were excellent in six patients (27%), good in fifteen (68%), fair in one (5%) and one (5%) had poor result. Discussion and conclusion. The present study indicates that the OK procedure provides significant pain relief and a functionally useful range of movement of more than 100°. The procedure can be used in high demand patients, wherein total elbow replacement is not indicated. It significantly reduces the disability in patients with significant elbow arthritis

This study assesses the clinical performance of the Souter-Strathclyde elbow arthroplasty with a standardised index and long term survivorship analysis. We undertook assessment of 68 primary Souter-Strathclyde total elbow replacements. Of 53 patients assessed with pre-operative Souter-Strathclyde charts, nine died and one was lost to follow-up, 43 had radiographic and telephone review, and 38 (88%) had clinical examination according to the Mayo Elbow Performance Index. Survival of the 43 elbows was to a mean of 72 months (range: eight to 187 months) with improvement in pain, motion, stability and function. Eight of 10 elbows in deceased patients had satisfactory scores at the last assessment. Ulnar neuropraxia occurred in eight elbows (12%), persistent sensory deficit in two (3%) and motor deficit in one. Two triceps abscesses required local skin flap cover. Revision was undertaken in 14 elbows (20%) for instability (six) bony injury (three), loosening (three) and intraoperative problems (two). The survivorship at 13 years was 74% with 62 (91%) of all elbows achieving a satisfactory Mayo score

Survival of the 43 elbows was to a mean of 72 months (range 8 to 187). A cohort of 25 elbows available for review with > 5-year follow up had improvement in pain, motion, stability and function. Eight of ten elbows in deceased patients had satisfactory scores at the last assessment. Ulnar neuropraxia occurred in eight elbows (12%), persistent sensory deficit in two (3%) and motor deficit in one. Two triceps abscesses required local skin flap cover. Revision was undertaken in 14 elbows (20%) for instability (6) bony injury (3), loosening (3) and intraoperative problems (2). The survivorship at 13 years was 74% with 62 (91%) of all elbows achieving a satisfactory Mayo score

New concepts in plate fixation have led to an evolution in plate design for olecranon fractures. The purpose of this study was. to compare the stiffness and strength of a contoured Locking Compression Plate (LCP) with a conventional plating method (one-third tubular plate) in a cadaveric comminuted olecranon fracture model with standardized osteotomy, and. to evaluate the LCP fixation method in a prospectively included group of patients with complex olecranon fractures using validated outcome scores. In the biomechanical study, five matched pairs of cadaveric elbows were randomly assigned for fixation by either LCP or a conventional plating method. Specimens were mounted to a custom-made testing bench and subjected to cyclic loading until failure occurred while measuring gapping at the osteotomy site. In the clinical study, twenty-one patients treated with LCP for complex olecranon fractures had a mean follow up of 20 months (3–39 months) and functional and patient rated outcome were evaluated. In the biomechanical study, there was no significant difference in fixation stiffness and strength between one third tubular plating and LCP (p > 0.05). In the clinical study, the mean time to union of the fracture was 6 months (2–28 months). According to the Mayo Elbow Performance Index (MEPI) most patients had a good or excellent outcome. No patients reported difficulty with activities of daily living. Physical capacity showed minimal loss of stability and strength. Six patients had their hardware removed. Technical ease of application and advantageous features of the LCP -such as unicortical screw fixation and improved holding power in osteopenic bone- make it a good alternative implant for comminuted olecranon fractures

To evaluate the results of open reduction in unreduced posterior dislocation of the elbow, done irrespective of the time since injury or age of the patient. Ten such cases in which the dislocation had been unreduced for more than 3 weeks since injury were included. Stiffness of the elbow was the main indication for the operation. Average age of the patient was 34.3 years (range 13 years to 65 years). Average time since injury was 3.9 months (range 2 month to 6 months). 3 patients had associated fractures around the elbow joint. All the patients had non functional elbow motion to perform any activity of daily living. We used speed’s procedure in all cases. At an average follow up of 18.5 months (range from 11 to 28 months), 8 patients achieved functional range of motion for activities of daily living and maintained an average arc of flexion(median) of 100 degrees and an average supination – pronation arc of 139.5 degrees. According to the Mayo Elbow Performance Index 5 patients achieved excellent results, 3 achieved good results and 2 achieved poor results. Complications included 2 cases of pin site infection, 1 case of ulnar neuritis and 1 case of delayed wound healing. We conclude that open reduction can provide painless, stable and functional elbow even in cases which are unreduced up to 6 months after the original injury

Previous studies have demonstrated the benefits of arthroscopic arthrolysis in relieving pain and improving motion in arthritic elbows, but none have reported the specific functional recovery. This study aims to review the functional outcome and patient satisfaction in a series of patients who underwent arthroscopic elbow arthrolysis for intrinsic stiffness, pain and arthritis not suitable for arthroplasty. Twenty six patients who underwent arthroscopic arthrolysis over a three year period were included. All patients were manual workers or strength athletes. All had pain and stiffness secondary to primary or secondary arthritis, with or without loose bodies. Pre- and post-operative evaluation included the Elbow Functional Assessment score, patient satisfaction and return to work and sports. The mean follow up period was 22 months. Function improved significantly in 87% with overall improvement in the Elbow Functional Assessment score from a preoperative score of 48 to a postoperative score of 84 (p< 0.05). All except three patients returned to their desired level of activity by 3 months postoperatively. Pain improved in 91%, mechanical symptoms in 80%, stiffness in all except one. The arc of elbow movement improved from 106° to 124° with a mean gain in elbow extension of 13°. Mayo elbow performance index also significantly improved postoperatively. Overall, 87% patients were very satisfied with the outcome. We conclude that the arthroscopic arthrolysis improves elbow function and returns patients to their desired level of activity, as well as improving range of motion and pain in patients with intrinsic elbow stiffness and pain

Background. Comminuted radial head fractures are challenging to treat with open reduction and internal fixation. Complicating matters further, radial head fractures are often associated with other elbow fractures and soft tissue injuries. Radial head arthroplasty is a favorable technique for the treatment of radial head fractures. The purpose of this study was to evaluate the functional outcomes of radial head arthroplasty using Modular Pyrocarbon radial head prosthesis in patients with unreconstructible radial head fractures. Methods. This single surgeon, single centre study retrospectively reviewed the functional and radiological outcomes of 21 consecutive patients requiring radial head arthroplasty for unreconstructible radial head fractures between July 2003 and July 2009. Patients were at least one year post-op and completed a Short-Form 36 (SF-36) questionnaire, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, and the Mayo Elbow Performance Index (MEPI). These patients were independently physically examined and their post-operative radiographs were independently reviewed. Results. 21 patients (9 males and 12 females) were reviewed at a minimum of 12 months follow-up. The mean DASH score was 10.8 (0-34.1), the mean SF-36 physical score was 76.9 (35-96), the mean SF-36 mental score was 83.8 (60-94), and their MEPI score was 86.4 (70-100). Patients maintained 90% of their grip strength in their injured arm when compared to their un-injured arm and had 17. o. of fixed flexion in the affected arm. Radiologically, 14 cases had some degree of post-traumatic osteoarthritis, 12 cases had evidence of heterotrophic ossification, 5 had some evidence of periprosthetic lucency and 3 of our cases were radiologically but not functionally ‘overstuffed’. Conclusion. Radial Head Arthroplasty with Pyrocarbon Radial Head Prosthesis is a safe and effective option when treating unreconstructable comminuted radial head fractures yielding good functional and radiological outcomes and remains the treatment option of choice at our institution

The purpose of this study was to demonstrate the beneficial effects of elbow arthrolysis. This was a prospective study on 88 patients with post-traumatic elbow stiffness with a mean follow-up of 51 months (1 year - 11 years), who had failed to improve their range of movement at a mimimum period of 6 months after their injury. All patients had an open arthrolysis. Post-operatively patients received continuous passive movement (CPM) for 48 to 72 hours. This was facilitated by good analgesia afforded by a continuous brachial plexus block. All patients received no physiotherapy thereafter and were advised to actively mobilise their elbow. ROM was assessed using a goniometer and function assessed using the Mayo elbow performance index. The ROM improved from a mean of 56 degrees pre-operatively to 106 degrees post-operatively. This improvement in ROM was reflected in the improvement of pre-operative flexion from 107 to 138 degrees and improvement of extension from 60 to 31 degrees. Function improved from a mean of 65 to 85 on the Mayo elbow performance score. 95% of the patients were satisfied with the outcome. Complications included ulnar nerve paraesthesia in 3 patients, 1 triceps avulsion and 1 superficial infection. 3 patients required a manipulation of the elbow in the postoperative period. This was performed within 2 weeks of the operation. There were no cases of elbow instability or heterotopic ossification in this series. Conclusion: Open elbow arthrolysis combined with continuous brachial plexus block and CPM in the postoperative period is a safe, reliable and durable procedure for improving ROM and function in patients with post-traumatic elbow stiffness

Introduction. The action of the radial head in the stability of the elbow is currently admitted. Its conservation is not always possible in complex fractures. The association with a posterolateral dislocation of the elbow leads to a higher risk of instability of the elbow joint and also at a longer term to degenerative changes. Some authors recommend the use of metallic radial head implant, acting as a spacer. The results seems encouraging but should the resection arthroplasty associated with the repair of the medial collateral ligament be abandoned?. Material and methods. In an amount of 35 consecutive patients who were taken in charge for an elbow dislocation 26 were included in this retrospective study, 13 of them had the association of a dislocation and a fracture of the radial head. In all 13 cases the radial head was considered as inadequate with a conservative treatment and was resected. The patients were assessed clinically according to the American Shoulder and Elbow Surgeons score (ASES) and the Mayo elbow performance index with a mean follow-up of 13 years (ranging from 5 to 15). The degenerative changes were assessed on plan × rays and an additional axial view according to the 4 stages described by Morrey. Results. No redislocation occurred. According to the Broberg/Morrey index 92% of the patients were considered as having a good result. They returned to work with no hindering. Signs of osteoarthritis grade 1 or 2 were observed and were clinically well tolerated. There was no difference for this item between the patients who conserved their radial head and those who sustained a resection. All patients were satisfied although they were protecting their joint against overuse while working. Discussion. The studies about the use of prosthesis of the radial head offer similar functional results. Degenerative changes on the trochleo ulnar joint are identical in all type of treatment. In order to prevent stiffness in the elbow joint an early post operative rehabilitation is recommended, it justifies a surgical stabilization associated with the use of an adapted dynamic splint. Conclusion. In case of elbow dislocation with a fracture of the radial head when its preservation is impossible, the resection without any prosthetic replacement remains a reasonable option if associated with a repair of the medial collateral ligament. At long term the functional results are still good with mild signs of osteoarthritis eliminating ipso facto the problem of an implant survivorship

Purpose: This study reviews the early results of elbow hemiarthroplasty for distal humeral fractures. Method: Elbow hemiarthroplasty was performed on 30 patients (mean 65 years; 29–91) for unreconstruc-table fractures of the distal humerus or salvage of failed internal fixation. A ‘triceps on’ approach was used in six and an olecranon osteotomy in 24. A Sorbie Questor prosthesis (Wright Medical Technology) was used in 14 patients and a Lattitude (Tornier) in 16. Clinical review at a mean of 25 months (3–88) included the American Shoulder and Elbow Surgeons elbow outcomes instrument (ASES), Mayo Elbow Performance Index (MEPI) and radiological assessment. Results: At follow up of 28 patients mean flexion deformity was 25 degrees, flexion 128 degrees, range of pro-nosupination 165 degrees, mean ASES 83, MEPI 77 and satisfaction 8/10. Acute cases scored better than salvage cases. Re-operation was required in 16 patients (53%); two revisions to a linked prosthesis for periprosthetic fracture and aseptic loosening at 53 and 16 months, 12 metalwork removals and four ulnar nerve procedures. Posterolateral rotatory instability was present in one elbow, four had laxity and pain on loading (two with prosthesis or pin loosening), four had laxity associated with column fractures (two symptomatic) and ten had asymptomatic laxity only. The triceps on approach had worse laxity and clinical scores. Uncomplicated union occurred in all olecranon osteotomies and 86% of column fractures. One elbow had an incomplete cement mantle and seven had lucencies > 1 mm; one was loose but acceptable. Five prostheses were in slight varus and two were flexed. Two elbows had early degenerative changes and 15 developed an osteophytic lip on the medial trochlea. Conclusion: Early results of elbow hemiarthroplasty show good outcomes after complex distal humeral fractures, despite a technically demanding procedure, met-alware removal in 40%, symptomatic laxity in 12% and column non-union in 8%. Better results are obtained for treatment in the acute setting and with use of an olecranon osteotomy

At follow up of 28 patients, mean flexion deformity was 25 degrees, flexion 128 degrees, range of pronosupination 165 degrees, mean ASES 83, MEPI 77 and satisfaction 8/10. Acute cases scored better than salvage cases. Re-operation was required in 16 patients (53%); 2 revisions to a linked prosthesis for periprosthetic fracture and aseptic loosening at 53 and 16 months, 12 metalwork removals and 4 ulnar nerve procedures. Posterolateral rotatory instability was present in one elbow, 4 had laxity and pain on loading (2 with prosthesis or pin loosening), 4 had laxity associated with column fractures (2 symptomatic) and 10 had asymptomatic laxity only. The triceps on approach had worse laxity and clinical scores. Uncomplicated union occurred in all olecranon osteotomies and 86% of column fractures. One elbow had an incomplete cement mantle and 7 had lucencies > 1 mm; one was loose but acceptable. 5 prostheses were in slight varus and 2 were flexed. 2 elbows had early degenerative changes and 15 an osteophytic lip on the medial trochlea. Elbow hemiarthroplasty has good early results after complex distal humeral fractures, despite a demanding procedure, metalware removal in 40%, symptomatic laxity in 12% and column non-union in 8%. Better results are obtained for treatment in the acute setting and with use of an olecranon osteotomy

This study reviews the early results of Distal Humeral Hemiarthroplasty(DHH) for distal humeral fracture and proposed a treatment algorithm incorporating the use of this technique in the overall management of distal humeral fractures. DHH was performed on 30 patients (mean 65 years; 29-91) for unreconstructable fractures of the distal humerus or salvage of failed internal fixation. A triceps on approach was used in six and an olecranon osteotomy in 24. A Sorbie Questor prosthesis (Wright Medical Technology) was used in 14 patients and a Latitude (Tornier) in 16. Clinical review at a mean of 25 months (3–88) included the American Shoulder and Elbow Surgeons elbow outcomes instrument (ASES), Mayo Elbow Performance Index (MEPI) and radiological assessment. At follow up of 28 patients mean flexion deformity was 25 degrees, flexion 128 degrees, range of pronosupination 165 degrees, mean ASES 83, MEPI 77 and satisfaction 8/10. Acute cases scored better than salvage cases. Re- operation was required in 16 patients (53%); two revisions to a linked prosthesis for periprosthetic fracture and aseptic loosening at 53 and 16 months, 12 metalwork removals and four ulnar nerve procedures. Posterolateral rotatory instability was present in one elbow, four had laxity and mild pain on loading (two with prosthesis or pin loosening), four had laxity associated with column fractures (two symptomatic) and 10 had asymptomatic mild laxity only. The triceps on approach had worse instability and clinical scores. Uncomplicated union occurred in all olecranon osteotomies and 86% of column fractures. One elbow had an incomplete cement mantle and seven had lucencies >1 mm; one was loose but acceptable. Five prostheses were in slight varus. Two elbows had early degenerative changes and 15 developed a medial spur on the trochlea. This is the largest reported experience of DHH. Early results of DHH show good outcomes after complex distal humeral fractures, despite a technically demanding procedure. Better results are obtained for treatment in the acute setting and with use of an olecranon osteotomy. As a result of this experience anatomical and clinical pre-requisites and advise on technique are outlined. An algorithm for use of DHH in relation to total elbow arthroplasty and ORIF for the treatment of complex intra-articular distal humeral fractures with or without column fractures is proposed

Purpose: To review the clinical outcome of patients who have had complex radial head fractures managed with titanium radial head replacement. Methods: There were 17 patients who had insertion of the radial head replacement. The indications for the prosthesis included acute Mason type III fracture which could not be stabilised satisfactorily with internal fixation. Other indications included delayed presentation including previously failed treatment. Patients were managed with radial head excision and insertion of the Wright Medical titanium radial head replacement. The lateral ligamentous complex was stabilised. A back slab was applied for a period of one week and then the elbow mobilised. The patients were followed up for a minimum of one year. The Mayo elbow performance index was used. Results: There were 7 patients with acute injuries of which 6 had associated injuries such as dislocation or coronoid process fracture. 6 of these patients had an excellent result and 1 had a good result. There were 9 patients with a delayed insertion of the radial head replacement. There were 3 patients who had an isolated radial head fracture and 6 patients with associated injuries, there were 2 excellent, 3 fair and 4 poor. Three of the 4 poor results had associated capitellar chondral injury. Two patients with fair results had other significant pathology in the upper limb. In the delayed presentation group the average flexion arc improved from 78 degrees to 102 degrees and the pro-supination improved from 117 degrees to 142 degrees. The average level of satisfaction on a visual analog score was 92 per cent. Conclusion: Patients who present with acute complex radial head fractures (including associated injuries), the results of radial head replacement are generally excellent. If there are significant associated injuries and a delay in presentation, then the outcome is often only fair. However, this group of patients have improvement in their pain, level of satisfaction and range of motion. Associated capitellar damage is a poor prognostic indicator

This cohort study reports outcomes of patients with comminuted radial head fractures treated with a modular radial head arthroplasty. Twenty-six patients (mean age = fifty-four) were prospectively followed at three, six, twelve, and twenty-four months following surgery. Patient satisfaction with this procedure was high. This data indicates favorable results using a modular radial head arthroplasty with rapid improvement in disability and physical impairment occurring in all measures in the first six months and further improvement in most patients up to two years. The Mayo Elbow Performance Index was at one year and eighty-four at two years. To investigate the objective and subjective outcomes of unreconstructable radial head fractures treated with a modular radial head arthroplasty. This data indicates favorable results using a modular radial head arthroplasty with improvement in satisfaction, disability and physical impairment occurring in all measures in the first six-months and continued improvement for up to two-years. Comminuted radial head fractures are challenging to treat with ORIF. Radial head arthroplasty is an alternative treatment that compares favorably to reported results for ORIF of similar fractures. Significant improvements were noted over time in self-reported and measured impairments as follows: ASES pain: baseline = 30/50, two years = 15/50; ASES function: baseline = 5/36, two years 27/36; MEPI one year = eighty-two, two years = eight-four. At two years, little impairment was observed compared to the unaffected side in grip 22/26 kg, flexion 141°/145°, or pronation 74°/79°. Moderate differences were noted in extension 28°/2°, supination 57°/72° and strength measures: extension = 29/38, flexion = 31/40, supination = 43/65, pronation = 37/53 (Nm). Patient satisfaction was high at three months (9/10) and remained high at two years (9.1/10). A cohort of twenty-six patients (seventeen female, mean age fifty-four) with non-reconstructable radial head fractures was treated using a modular metallic radial head arthroplasty (Evolve TM, Wright Medical Technology, Arlington, TN). All patients were prospectively followed at three, six, twelve and twenty-four months. Self-report of limb function, general health, measured ROM and isometric strength were assessed by an independent observer. Funding Institution research foundation support was provided by Wright Medical Technology.

Post-traumatic elbow stiffness is a disabling condition that remains challenging for upper limb surgeons. Open elbow arthrolysis is commonly used for the treatment of stiff elbow when conservative therapy has failed. Multiple questions commonly arise from surgeons who deal with this disease. These include whether the patient has post-traumatic stiff elbow, how to evaluate the problem, when surgery is appropriate, how to perform an excellent arthrolysis, what the optimal postoperative rehabilitation is, and how to prevent or reduce the incidence of complications. Following these questions, this review provides an update and overview of post-traumatic elbow stiffness with respect to the diagnosis, preoperative evaluation, arthrolysis strategies, postoperative rehabilitation, and prevention of complications, aiming to provide a complete diagnosis and treatment path.

Aims

The aim of this study was to report the mid-term clinical outcome of cemented unlinked J-alumina ceramic elbow (JACE) arthroplasties when used in patients with rheumatoid arthritis (RA).
