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

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.

Introduction. Distal triceps tendon rupture is related to high complication rates with up to 25% failures. Elbow stiffness is another severe complication, as the traditional approach considers prolonged immobilization to ensure tendon healing. Recently a dynamic high-strength suture tape was designed, implementing a silicone-infused core for braid shortening and preventing repair elongation during mobilization, thus maintaining constant tissue approximation. The aim of this study was to biomechanically compare the novel dynamic tape versus a conventional high-strength suture tape in a human cadaveric distal triceps tendon rupture repair model. Method. Sixteen paired arms from eight donors were used. Distal triceps tendon rupture tenotomies and repairs were performed via the crossed transosseous locking Krackow stitch technique for anatomic footprint repair using either conventional suture tape (ST) or novel dynamic tape (DT). A postoperative protocol mimicking intense early rehabilitation was simulated, by a 9-day, 300-cycle daily mobilization under 120N pulling force followed by a final destructive test. Result. Significant differences were identified between the groups regarding the temporal progression of the displacement in the distal, intermediate, and proximal tendon aspects, p<0.001. DT demonstrated significantly less displacement compared to ST (4.6±1.2mm versus 7.8±2.1mm) and higher load to failure (637±113N versus 341±230N), p≤0.037. DT retracted 0.95±1.95mm after each 24-hour rest period and withstood the whole cyclic loading sequence without failure. In contrast, ST failed early in three specimens. Conclusion. From a biomechanical perspective, DT revealed lower tendon displacement and greater resistance in load to failure over ST during simulated daily mobilization, suggesting its potential for earlier elbow mobilization and prevention of postoperative elbow stiffness

Standard fixation for intra-articular distal humerus fracture is open reduction and internal fixation (ORIF). However, high energy fractures of the distal humerus are often accompanied with soft tissue injuries and or vascular injuries which limits the use of internal fixation. In our report, we describe a highly complex distal humerus fracture that showed promising healing via a ring external fixator. A 26-year-old man sustained a Gustillo Anderson Grade IIIB intra-articular distal humerus fracture of the non-dominant limb with bone loss at the lateral column. The injury was managed with aggressive wound debridement and cross elbow stabilization via a hinged ring external fixator. Post operative wound managed with foam dressing. Post-operatively, early controlled mobilization of elbow commenced. Fracture union achieved by 9 weeks and frame removed once fracture united. No surgical site infection or non-union observed throughout follow up. At 2 years follow up, flexion - extension of elbow is 20°- 100°, forearm supination 65°, forearm pronation 60° with no significant valgus or varus deformity. The extent of normal anatomic restoration in elbow fracture fixation determines the quality of elbow function with most common complication being elbow stiffness. Ring fixator is a non-invasive external device which provides firm stabilization of fracture while allowing for adequate soft tissue management. It provides continuous axial micro-movements in the frame which promotes callus formation while avoiding translation or angulation between the fragments. In appropriate frame design, they allow for early rehabilitation of joint where normal range of motion can be allowed in controlled manner immediately post-fixation. Functional outcome of elbow fracture from ring external fixation is comparable to ORIF due to better rehabilitation and lower complications. Ring external fixator in our patient achieved acceptable functional outcome and fracture alignment meanwhile the fracture was not complicated with common complications seen in ORIF. In conclusion, ring external fixator is as effective as ORIF in treating complex distal humeral fractures and should be considered for definitive fixation in such fractures

Aim: Postraumatic elbow stiffness is a common condition after elbow trauma. Sometimes it is a quite disabling symptom not responding to conservative measures. We present the surgical treatment of such cases of posttraumatic elbow stiffness. Material: Twenty three patients, fourteen male and nine female with an average age of 34 yrs, underwent a surgical treatment of their stiff elbow. The average preoperative range of motion regarding elbow flexion-extension was 65° and the average rotational movement was 123°. All patients had received a resection of the anterior capsule, release or resection of posterior elements, removal of loose bodies and resection of osseous beaks if it was necessary. Two patients received a triceps lengthening. The results evaluated with the Mayo Elbow Performance Score. Results: The average follow up was twenty nine months. All the patients were available for clinical assessment. There was an improvement of the average ROM to 115°, regarding flexion extension and to 164° regarding supination pronn. Postoperatively a dynamic elbow splint was used in twenty patients and a hinged external fixator in the remaining patients. Revision elbow release was performed in three patients and in one patient the elbow stiffness was deteriorated. Sixteen patients had an excellent or good result, and seven had a fair or poor one. Conclusion: Elbow stiffness is an extremely disabling condition causing a functional impairment. Surgical elbow release is quite reliable, and relatively safe procedure given the fact that the patient follows strictly the rehabilitation protocol

Background: The treatment of post-traumatic elbow stiffness has seen many important changes over the years, particularly greater the development of arthroscopy. In this study mid-term clinical results of arthroscopy for post-traumatic elbow stiffness are evaluated in 15 sporting patients, with an average age of 32. Methods: 8 patients reported post-traumatic stiffness due to fracture of the radial head, 3 to fracture-dislocation, 1 to fracture of the radial diaphysis complicated by osteosynthesis, and the remaining 3 patients to stress syndromes with osteochondral detachment. Surgical treatment consists in debridment, arthroscopic capsular release, and removal of bone fragments by arthroscopy. Patients were followed-up from 4 up to 36 months, with a mean follow-up time of 18 months. Results: Results obtained have been good to excellent in 84% of cases with a average range in post-operative movement of 13–137° and reduction in pain symptomatology. Conclusion: In light of our mid-term clinical results on a small series of cases, arthroscopic surgical treatment would appear to be an acceptable option in management of the post-traumatic stiff elbow

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

Aim:. To investigate the clinical outcomes of elbows with post-traumatic stiffness treated by open surgical release. Methods:. A retrospective review was completed on thirty-five consecutively managed patients who underwent an open elbow release for post-traumatic stiffness between 2007 and 2012. Pre-operative and post-operative range of motion (ROM), pain scores and functional outcomes were recorded. Results:. Mean follow-up was 31 months (6–84). The cohort consisted of 20 male and 15 female patients with an average age at time of surgery of 34 years (17–59). The interval from injury to time of release was 26 months (6–180). An improvement in mean ROM from 49° (0°–105°) to 102° (55°–150°) was obtained. The improvement in ROM in patients with pre-operative heterotopic bone was 61° compared to 45° in patients without heterotopic bone. The mean Mayo Elbow Performance Score improved from 44 pre-operatively to 82 at most recent follow-up. Mean VAS scores improved from 5.9 pre-operatively to 2.8 at most recent follow-up. Patients rated the affected elbow a mean of 73% as compared to the contralateral/normal side (50–100%). Apart from a 10% incidence of transient ulnar nerve neurapraxia in patients who had a medial or combined approach, complication rates and functional outcomes were comparable between medial, lateral and combined approaches. Conclusion:. Open release for post-traumatic elbow stiffness results in satisfactory functional outcomes in the majority of cases, with no significant differences between medial, lateral or combined approaches

Aims

The management of fractures of the medial epicondyle is one of the greatest controversies in paediatric fracture care, with uncertainty concerning the need for surgery. The British Society of Children’s Orthopaedic Surgery prioritized this as their most important research question in paediatric trauma. This is the protocol for a randomized controlled, multicentre, prospective superiority trial of operative fixation versus nonoperative treatment for displaced medial epicondyle fractures: the Surgery or Cast of the EpicoNdyle in Children’s Elbows (SCIENCE) trial.

Aims

There are concerns regarding complications and longevity of total elbow arthroplasty (TEA) in young patients, and the few previous publications are mainly limited to reports on linked elbow devices. We investigated the clinical outcome of unlinked TEA for patients aged less than 50 years with rheumatoid arthritis (RA).

Aims

The aim of this study was to develop and internally validate a prognostic nomogram to predict the probability of gaining a functional range of motion (ROM ≥ 120°) after open arthrolysis of the elbow in patients with post-traumatic stiffness of the elbow.

Summary. In contrast to the current literature, myofibroblasts are not present in chronic posttraumatic elbow contractures. However, myofibroblasts are present in the acute phase after an elbow fracture and/or dislocation. This suggests a physiological role in normal capsule healing and a potential role in the early phase of posttraumatic contracture formation. Introduction. Elbow stiffness is a common complication after elbow trauma. The elbow capsule is often thickened, fibrotic and contracted upon surgical release. The limited studies available suggest that the capsule is contracted because of fibroblast to myofibroblast differentiation. However, the timeline is controversial and data on human capsules are scarce. We hypothesise that myofibroblasts are absent in normal capsules and early after acute trauma and elevated in patients with posttraumatic elbow contracture. Patients & Methods. We obtained twenty-one human elbow joint capsules within fourteen days after an elbow fracture and/or dislocation and thirty-four capsules from thirty-four patients who had operative release of posttraumatic contractures greater than five months after injury. Myofibroblasts in the joint capsules were quantified using immunohistochemistry. Alpha-smooth muscle actin (α-SMA) was used as a marker for myofibroblasts. Samples were characterised and scored by an independent pathologist blinded for clinical data. Results. Eleven capsules were associated with the acute phase after trauma (hours to 7 days), and staining for α-SMA was negative in all eleven specimens. Ten specimens were associated with a later phase post trauma with myofibroblasts staining positive for α-SMA in all but two. All, but two, thirty-four long standing contractures showed a histological pattern consistent with chronic stages of fibrosis, characterised by increased fibroblast-like cell proliferation and higher cellular density of fibroblast-like cells with highly unstructured collagen. There was no staining of α-SMA in fibroblast-like cells in, all but two of these longstanding contractures suggesting absence of myofibroblasts. Conclusions. This study present ‘negative results’ on the hypothesis that myofibroblast numbers are elevated in longstanding (> 5 months) human posttraumatic elbow capsules. This is in contrast to all studies on human tissue in the literature to date. One recent animal study is in agreement withy our data. We did find some myofibroblasts in elbow capsules in the late-phase posttrauma (between 7 and 14 days) suggesting a potential role in early phase of posttraumatic contracture formation

Elbow contracture is a well recognised sequel of neuromuscular disorders and can be a rather debilitating condition. Non operative treatment, such as physiotherapy and splinting, results in an improved range of motion, but since musculoskeletal pathology in neuromuscular diseases is progressive, an open surgical release of the elbow is often required. Therefore, the purpose of the present study was to assess the results of surgical treatment of elbow stiffness in patients suffering from neuromuscular disorders. Between January 2000 and October 2008, 11 patients with neuromuscular diseases underwent surgical treatment of elbow contracture. The mean age of the patients was 21 years. Eight patients had cerebral palsy, 2 arthrogryposis and 1 brachial plexus palsy. Pre-operatively the lag of elbow flexion and extension was 45° and 38° respectively. In 6 patients releases were performed through a lateral approach, while 3 required an additional medial incision. In 2 patients the pathology was addressed through a posterior approach. The mean follow up was 26 months. Postoperatively one patient developed skin necrosis which was treated conservatively. Furthermore, another patient developed transient ulnar neuritis, and finally one more presented with medial collateral ligament insufficiency. All patients had an improved functional arc of motion. Namely, the lag of elbow flexion and extension was reduced to 22° and 10° respectively. At the final follow up the patients maintained 90% of the range of motion that was achieved immediately postoperatively. Open release of the elbow contracture in neuromuscular diseases yield satisfactory results. Therefore, it can be expected that patients will obtain a functional range of motion

To study the surgical outcome of multi-fragmentary, un-reconstructable radial head fractures managed acutely by a radial head prosthetic replacement, we retrospectively reviewed nineteen radial head fractures that were treated acutely with a radial head replacement, over a four-year period in three district general hospitals. Nineteen patients were clinically and radiologically assessed for this study. Functional assessment was performed with the Mayo elbow performance score (MEPS). No patient achieved full functional range of motion. The average range of flexion was 110° (range 80° to 120°), average extension deficit of 35° (range 30° to 45°), average pronation was 35° (range 0° to 65°), and average supination was 50° (range 30° to 85°). Complications included implant removal due to loosening (n=1), elbow stiffness (n=2), and instability (n=1), the latter case requiring a revision of the radial head prosthesis. Some degree of persistent discomfort was noticed in all cases. Five patients were tolerant of the final functional outcome. The average Mayo elbow score was 68/100 (range 55 to 80). One patient had an intra-operative fracture of the radial metaphysis during insertion of the implant. Conclusions. Radial head replacement in general orthopaedic, low volume practice failed to achieve satisfactory results. Contrary to popular belief, it is a technically demanding operation, for which surveillance should be continued for a minimum of one year. Strict indications for prosthetic replacement should be followed and implant selection has yet to be proven to make a significant positive contribution. Our review highlights the need for a stricter adherence to indications; surgery should not be under-estimated and devolved to trainees, and our understanding of the radial axis of the elbow and forearm remains relatively rudimentary

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. Over the last 15 years there has been a series of publications reporting the beneficial effects of elbow arthrolysis, with considerable variation in operative technique and post-operative management. Many advocate the use of passive stretching techniques in the early post-operative period if range of motion fails to improve satisfactorily. The purpose of this study was to assess our results of open elbow arthrolysis in patients who did not receive any passive stretching after discharge from hospital. Methods. Prospectively collected data of 55 patients with a minimum follow-up of 1 year after arthrolysis were analysed. All procedures were performed by the same surgeon (LR), achieving as much improvement in elbow motion as possible at operation. All patients had continuous brachial plexus blocks and continual passive motion for 2-3 days post-operatively but none received any passive stretching after discharge. At review, a senior physiotherapist (BD) formally assessed all the patients. Results. All patients' arc of movement improved from 68 degrees to 104 degrees (flexion 18 degrees/extension 23 degrees). Upper limb function (Disabilities of the Arm, Shoulder and Hand score) improved by 50%. Pain decreased from 20 to 9, measured with a Visual Analogue Score. The greatest improvement in motion was obtained in the stiffest elbows - 7 patients with an arc of 30 degrees or less pre-operatively achieved an arc of 100 degrees by the time of the last review. Conclusions. Good results of open arthrolysis for post-traumatic elbow stiffness can be achieved with continuous brachial plexus blocks and continual passive motion for 2-3 days post-operatively. There appears to be little evidence to support treatment with passive stretching techniques after discharge from hospital, as our results are similar to other reported series

Aim: To assess the functional and occupational outcome of open elbow arthrolysis for post-traumatic contractures. Materials and Methods: Prospective evaluation of 60 consecutive cases (86% male,14%female) of post-traumatic extrinsic elbow stiffness. Average age was 37 years (24–48). Moderate to high physical demand at work in 96% of cases. 56% of cases involved the right side. Open arthrolysis (column procedure) trough a lateral (72%) or posterior (28%) approach followed a minimum rehabilitation period of 6 months post original injury. In 8 cases, an anterior transposition of the ulnar nerve was required. Patients received postoperative analgesia with Bupivacaine 0,0125% trough an indwelling catheter. No chemical or radiotherapy ectopic calcification prophylaxis was used. Postoperative complications, range of motion, X-ray evaluation, time to return to work, activity level and workers’ compensation were evaluated at the end of follow-up (24 months, range 12–36). Results: Complications occurred in 14% of cases. Two patients required revision surgery for ectopic calcifications restricting prono-supination. The flexo-extension (FE) arc of motion improved from 49 ° to 115 ° and that of prono-supination (PS) from 100 ° to 158 ° The results were found to be statistically significant for FE (p= 0.054) and PS (p> 0,00001). In 20% of cases, patients returned to their previous job with some restrictions (33% disability) and 12% changed to a less physically demanding occupation. Conclusions: Open arthrolysis is an effective surgical procedure to improve mobility in post-traumatic stiff elbows. It is indicated when the joint interline is preserved. Good functional and occupational outcome in a high percentage of case in the working population was observed

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
