Abstract
Heterotopic ossification (HO) is characterized by the formation of pathological bone within the soft tissues. HO predominantly affects elbow joints and may be accompanied by tardy ulnar nerve palsy. This study aimed to explore the clinical and functional outcomes of patients with tardy ulnar nerve palsy caused by HO following surgical treatment, with a review of the relevant literature. A retrospective study was conducted on 4 patients with tardy ulnar nerve palsy caused by HO, who underwent anterior subcutaneous ulnar nerve transposition between 2015 and 2020. The patients were followed up for more than 1 year and the cause of HO was also identified. Clinical and functional outcomes were evaluating using the grip strength and pinch strength, visual analog scale (VAS) pain score and Quick disabilities of the arm, shoulder and hand (DASH) score. The causes of HO were repetitive micro-trauma in 1 case and excessive physical or rehabilitation therapy in 3 cases. The average follow-up period was 15.6 months (range; 12-21 months). The grip strength increased from an average of 14kg to 26.5kg. The pinch strength increased from an average of 1.5 kg to 3.63 kg. The Quick DASH score decreased from an average of 55.6 to 6.15. The VAS score for pain decreased from an average of 7 to 0.25. Rapid surgical treatment, including removal of the heterotopic bone and ulnar nerve anterior transposition, might improve outcomes in patients with tardy ulnar nerve palsy caused by HO.

Abstract
Background This case report describes the occurrence of a rare heterotopic ossification of the elbow joint in a child, caused by inappropriate movement after trauma. A successful operation to remove heterotopic ossification was described in the report with satisfactory results. Case presentation A 7-year-old boy suffered a supracondylar fracture of the humerus after an accidental fall, and after immobilization with a cast, improper movement resulted in heterotopic ossification of the elbow joint, which severely affected joint function. The heterotopic ossification was surgically removed and a complete recovery was demonstrated at 18 months follow-up. The heterotopic ossification was successfully removed with good elbow function and no recurrence at 18 months follow-up. Conclusions The purpose of this report is to show the good results with surgical treatment of heterotopic ossification of the elbow joint in children,when conservative treatment does not work.

Activation of BMP4/SMAD pathway by HIF-1α in hypoxic environment promotes osteogenic differentiation of BMSCs and leads to ectopic bone formation. Tissue Cell 2024; 88:102376. [PMID: 38608407 DOI: 10.1016/j.tice.2024.102376] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2023] [Revised: 03/15/2024] [Accepted: 04/04/2024] [Indexed: 04/14/2024]
Abstract
OBJECTIVE Heterotopic ossification (HO), also known as ossifying myositis, is a condition that produces abnormal bone and cartilage tissue in the soft tissues. Hypoxia inducible factor lα (HIF-lα) regulates the expression of various genes, which is closely related to the promotion of bone formation, and Drosophila mothers against decapentaplegic protein (SMAD) mediates the signal transduction in the Bone morphogenetic protein (BMP) signaling pathway, which affects the function of osteoblasts and osteoclasts, and thus plays a key role in the regulation of bone remodeling. We aimed to investigate the mechanism by which HIF-1α induces osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) in a hypoxic environment. METHODS A cellular hypoxia model was constructed to verify the expression of HIF-1α, while alizarin red staining was performed to observe the osteogenic differentiation ability of bone marrow mesenchymal stem cells (BMSCs). Alizarin red staining was used to analyze the late mineralization ability of the cells. Western blot analysis was performed to analyze the expression levels of osteogenesis-related factors OCN, OPN proteins as well as the pathway proteins BMP4, p-Smad1/5/8, and Smad1. We also constructed a rat model of ectopic bone formation, observed ectopic ossification by X-ray, and verified the success of the rat model by ELISA of HIF-1α. HE staining was used to observe the matrix and trabecular structure of bone, and Masson staining was used to observe the collagen and trabecular structure of bone. Immunohistochemistry analyzed the expression of OCN and OPN in ectopic bone tissues, and WB analyzed the expression of pathway proteins BMP4, p-Smad1/5/8 and Smad1 in ectopic bone tissues to verify the signaling pathway of ectopic bone formation. RESULTS Our results indicate that hypoxic environment upregulates HIF-1a expression and activates BMP4/SMAD signaling pathway. This led to an increase in ALP content and enhanced expression of the osteogenesis-related factors OCN and OPN, resulting in enhanced osteogenic differentiation of BMSCs. The results of our in vivo experiments showed that rats inoculated with BMSCs overexpressing HIF-1α showed bony structures in tendon tissues, enhanced expression of the bone signaling pathways BMP4 and p-Smad1/5/8, and enhanced expression levels of the osteogenic-related factors OCN and OPN, resulting in the formation of ectopic bone. CONCLUSIONS These data further suggest a novel mechanistic view that hypoxic bone marrow BMSCs activate the BMP4/SMAD pathway by up-regulating the expression level of HIF-1α, thereby promoting the secretion of osteogenic factors leading to ectopic bone formation.

J Shoulder Elbow Surg 2024; 33:1092-1103. [PMID: 38286182 DOI: 10.1016/j.jse.2023.12.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 11/21/2023] [Accepted: 12/04/2023] [Indexed: 01/31/2024]
Abstract
BACKGROUND Ulnar neuropathy at the elbow caused by heterotopic ossification (HO) is a rare condition. This retrospective study aims to report on 32 consecutive cases of ulnar nerve encasement caused by elbow HO and evaluate long-term outcomes of operative management and a standardized postoperative rehabilitation regimen. METHODS A retrospective case series was conducted on 32 elbows (27 patients) that underwent operative management of bony ulnar nerve encasement. All procedures were performed in the inpatient setting at an Academic Level 1 Trauma Center from September 1999 to July 2021 by one of 3 fellowship-trained shoulder and elbow. Postoperatively, all patients received formal physical therapy, HO prophylaxis (30 received indomethacin, 2 received radiation), and a structured continuous passive motion machine regimen. Patient demographics, age, gender, type of injury, history of tobacco use, and medical comorbidities were obtained to include in the analysis. Long-term follow-up examinations were performed to evaluate elbow flexion-extension arc of motion, Mayo Elbow Performance Score, and visual analog scale pain scores. RESULTS Thirty-two elbows with complete bony ulnar nerve encasement secondary to HO were identified (14 from burns, 15 from trauma, 3 closed head injuries). Following surgery, the mean flexion-extension arc of motion improved significantly, increasing from 21° to 100° at long-term follow-up (average 8.7 years, range 2-17 years), with statistically significant improvements in preoperative vs. long-term postoperative elbow extension (P < .001), flexion (P < .001), and total arc of motion (P < .001). There was a statistically significant improvement in pre- vs. postprocedure ulnar nerve function, as demonstrated by a decrease in average McGowan grade (1.2-0.7; P = .002). Additionally, 63% of patients with preoperative ulnar neuropathy symptoms (20/32) had either complete resolution or subjective improvement after surgery. The mean time from injury to surgery was 518 days (range 65-943 days). Age, gender, time to surgery, and medical comorbidities were not associated with outcomes. The complication rate was 9% (3/32). Patients had an average flexion-extension arc of motion of 97° and average Mayo Elbow Performance Score of 80 ("good") at long-term follow-up. CONCLUSIONS The combination of operative management, postoperative HO prophylaxis, and a regimented rehabilitation program has proven to be a durable solution for treating and ensuring good long-term functional outcomes for patients with elbow HO and bony ulnar nerve encasement. This treatment approach leads to superior range of motion, improved or resolved ulnar neuropathy, and good to excellent long-term functional outcomes.

Abstract
INTRODUCTION Exaggerated inflammatory response is one of the main mechanisms underlying heterotopic ossification (HO). It has been suggested that the antifibrinolytic drug tranexamic acid (TXA) can exert a significant anti-inflammatory effect during orthopaedic surgery. However, no prospective studies have yet investigated the effects of TXA on HO recurrence in patients following open elbow arthrolysis (OEA). METHODS AND ANALYSIS Here, we present a protocol for a single-centre, randomised, double-blind, placebo-controlled trial to investigate the effectiveness of TXA on HO recurrence after OEA in a single hospital. A minimum sample size of 138 eligible and consenting participants randomised into treatment and control groups in a 1:1 manner will be included. Patients will receive 2 g of intravenous TXA (experimental group) or placebo (normal saline, control group) administered before skin incision. The primary outcome is HO recurrence rate within 12 months after surgery. The secondary outcomes are the serum immune-inflammatory cytokines including erythrocyte sedimentation rate, C reactive protein, interleukin (IL)-6, IL-1β, IL-13 at the first and third day postoperatively, and elbow range of motion and functional score at 1.5, 6, 9 and 12 months after surgery. After completion of the trial, the results will be reported in accordance with the extensions of the Consolidated Standards of Reporting Trials Statement for trials. The results of this study should determine whether TXA can reduce the rates of HO occurrence after OEA. ETHICS AND DISSEMINATION Ethical approval has been granted by the Medical Ethics Committee of the Shanghai Sixth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine (reference number 2022-123-(1)). The results of this study will be disseminated through presentations at academic conferences and publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER ChiCTR2300068106.

Abstract
BACKGROUND Heterotopic ossification (HO) is one of the most intractable conditions following injury to the musculoskeletal system. In recent years, much attention has been paid to the role of lncRNA in musculoskeletal disorders, but its role in HO was still unclear. Therefore, this study attempted to determine the role of lncRNA MEG3 in the formation of post-traumatic HO and further explore the underlying mechanisms. RESULTS On the basis of high-throughput sequencing and qPCR validation, elevated expression of the lncRNA MEG3 was shown during traumatic HO formation. Accordingly, in vitro experiments demonstrated that lncRNA MEG3 promoted aberrant osteogenic differentiation of tendon-derived stem cells (TDSCs). Mechanical exploration through RNA pulldown, luciferase reporter gene assay and RNA immunoprecipitation assay identified the direct binding relationship between miR-129-5p and MEG3, or miR-129-5p and TCF4. Further rescue experiments confirmed the miR-129-5p/TCF4/β-catenin axis to be downstream molecular cascade responsible for the osteogenic-motivating effects of MEG3 on the TDSCs. Finally, experiments in a mouse burn/tenotomy model corroborated the promoting effects of MEG3 on the formation of HO through the miR-129-5p/TCF4/β-catenin axis. CONCLUSIONS Our study demonstrated that the lncRNA MEG3 promoted osteogenic differentiation of TDSCs and thus the formation of heterotopic ossification, which could be a potential therapeutic target.

Abstract
Heterotopic ossification occurs as a pathological ossification condition characterized by ectopic bone formation within soft tissues following trauma. Vascularization has long been established to fuel skeletal ossification during tissue development and regeneration. However, the feasibility of vascularization as a target of heterotopic ossification prevention remained to be further clarified. Here, we aimed to identify whether verteporfin as a widely used FDA-approved anti-vascularization drug could effectively inhibit trauma-induced heterotopic ossification formation. In the current study, we found that verteporfin not only dose dependently inhibited the angiogenic activity of human umbilical vein endothelial cells (HUVECs) but also the osteogenic differentiation of tendon stem cells (TDSCs). Moreover, YAP/β-catenin signaling axis was downregulated by the verteporfin. Application of lithium chloride, an agonist of β-catenin, recovered TDSCs osteogenesis and HUVECs angiogenesis that was inhibited by verteporfin. In vivo, verteporfin attenuated heterotopic ossification formation by decelerating osteogenesis and the vessels densely associated with osteoprogenitors formation, which could also be readily reversed by lithium chloride, as revealed by histological analysis and Micro-CT scan in a murine burn/tenotomy model. Collectively, this study confirmed the therapeutic effect of verteporfin on angiogenesis and osteogenesis in trauma-induced heterotopic ossification. Our study sheds light on the anti-vascularization strategy with verteporfin as a candidate treatment for heterotopic ossification prevention.

Abstract
Dislocations of the elbow joint are among the most prevalent dislocation injuries in the human body after shoulder joint dislocations and represent a challenge in the clinical routine because of the concomitant injuries and complications. They predominantly affect young adults who become injured during athletic or daily activities. A distinction is generally made between a simple elbow dislocation and a dislocation fracture of the elbow; however, a uniform classification or treatment algorithm has not yet been established, especially for simple elbow dislocations with associated ligamentous, muscular and capsular concomitant injuries. Due to this and the complexity of this injury, a standardized approach is needed to initiate the optimal treatment at an early stage and to correctly select the narrow treatment pathway between impending chronic instability and elbow stiffness.

Abstract
Heterotopic ossification (HO) refers to benign ectopic bone formation in soft tissue and is common following trauma surgery. HO bone can restrict movement and progress into ankylosis that may necessitate surgical intervention. This article discusses the current literature on the pathophysiology, prophylaxis, treatment, and epidemiology of postoperative HO following orthopedic trauma.

Pathophysiology and Emerging Molecular Therapeutic Targets in Heterotopic Ossification. Int J Mol Sci 2022; 23:ijms23136983.

Abstract
The term heterotopic ossification (HO) describes bone formation in tissues where bone is normally not present. Musculoskeletal trauma induces signalling events that in turn trigger cells, probably of mesenchymal origin, to differentiate into bone. The aetiology of HO includes extremely rare but severe, generalised and fatal monogenic forms of the disease; and as a common complex disorder in response to musculoskeletal, neurological or burn trauma. The resulting bone forms through a combination of endochondral and intramembranous ossification, depending on the aetiology, initiating stimulus and affected tissue. Given the heterogeneity of the disease, many cell types and biological pathways have been studied in efforts to find effective therapeutic strategies for the disorder. Cells of mesenchymal, haematopoietic and neuroectodermal lineages have all been implicated in the pathogenesis of HO, and the emerging dominant signalling pathways are thought to occur through the bone morphogenetic proteins (BMP), mammalian target of rapamycin (mTOR), and retinoic acid receptor pathways. Increased understanding of these disease mechanisms has resulted in the emergence of several novel investigational therapeutic avenues, including palovarotene and other retinoic acid receptor agonists and activin A inhibitors that target both canonical and non-canonical signalling downstream of the BMP type 1 receptor. In this article we aim to illustrate the key cellular and molecular mechanisms involved in the pathogenesis of HO and outline recent advances in emerging molecular therapies to treat and prevent HO that have had early success in the monogenic disease and are currently being explored in the common complex forms of HO.

Abstract
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. METHODS We developed the Shanghai Prediction Model for Elbow Stiffness Surgical Outcome (SPESSO) based on a dataset of 551 patients who underwent open arthrolysis of the elbow in four institutions. Demographic and clinical characteristics were collected from medical records. The least absolute shrinkage and selection operator regression model was used to optimize the selection of relevant features. Multivariable logistic regression analysis was used to build the SPESSO. Its prediction performance was evaluated using the concordance index (C-index) and a calibration graph. Internal validation was conducted using bootstrapping validation. RESULTS BMI, the duration of stiffness, the preoperative ROM, the preoperative intensity of pain, and grade of post-traumatic osteoarthritis of the elbow were identified as predictors of outcome and incorporated to construct the nomogram. SPESSO displayed good discrimination with a C-index of 0.73 (95% confidence interval 0.64 to 0.81). A high C-index value of 0.70 could still be reached in the interval validation. The calibration graph showed good agreement between the nomogram prediction and the outcome. CONCLUSION The newly developed SPESSO is a valid and convenient model which can be used to predict the outcome of open arthrolysis of the elbow. It could assist clinicians in counselling patients regarding the choice and expectations of treatment. Cite this article: Bone Joint J 2022;104-B(4):486-494.

Long-term outcomes of open arthrolysis combined with radial head arthroplasty for post-traumatic elbow stiffness: results are durable over 8 years. J Shoulder Elbow Surg 2022; 31:509-521. [PMID: 34808353 DOI: 10.1016/j.jse.2021.10.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2021] [Revised: 10/17/2021] [Accepted: 10/23/2021] [Indexed: 02/01/2023]
Abstract
BACKGROUND Post-trauma elbow stiffness (PTES) is a common complication after elbow trauma that causes severe upper limb disability. Open elbow arthrolysis (OEA) with radial head arthroplasty (RHA) is an effective method to treat PTES with rotation limitation, or persistent pain/instability after radial head resection. However, no long-term results have been reported for this technique. This study aimed to show the clinical and radiographic outcomes of OEA with RHA over 8 years and compare its efficacy at 3 years (short-term). METHODS Patients with PTES treated by OEA with RHA between September 2010 and December 2012 were retrospectively reviewed. Seventeen patients were followed up over 8 years (range, 100-106 months). A bipolar prosthesis of RHA was performed during OEA. Preoperative, 3-year, and 8-year elbow and forearm motion, upper limb function, radiographic outcomes, and complications were recorded. RESULTS Clinically important improvements in elbow motion and forearm rotation were obtained, from 34° and 58° preoperatively, to 109° and 135° at 3 years, which were maintained over 8 years, to 113° (P = .262) and 134° (P = .489). The Mayo Elbow Performance Index had clinically important increases from the preoperative level of 58 to 94 points at 3 years, and was maintained over 8 years (95 points, P = .422), with 100% reporting excellent to good outcomes. Pain and nerve symptoms were also improved. Complications consisted of new-onset ulnar nerve symptoms in 1 patient, nonclinically significant heterotopic ossification recurrence in 3, humeroulnar arthritis exacerbation in 4, and periprosthetic lucency in 8. CONCLUSIONS OEA with RHA yielded satisfactory short-term outcomes for PTES at 3 years, with substantial improvements in elbow mobility and function, and the results were durable over the long term (8 years).

Abstract
Neurogenic heterotopic ossifications (NHOs) are periarticular ectopic ossifications that frequently develop after a central nervous system injury, most often a traumatic one. They limit range of motion and cause pain, interfering with limb positioning and function, whether active or passive. Highly described in the lower limbs, NHOs can also develop in the upper limb, with specific characteristics depending on their location. This article provides a summary of the diagnostic and therapeutic management of NHOs in the upper limb, based on the current literature.

Abstract
Trauma-induced heterotopic ossification (HO) is the aberrant extra-skeletal bone formation that severely incapacitates patient's daily life. Inflammation is the first stage of this progression, becoming an appealing target of early therapeutic intervention. Metformin, a widely used antidiabetic drug, also poses the therapeutic potential to modulate various inflammatory-related diseases. Therefore, this study aimed to investigate the preventive effect of metformin on trauma-induced HO progression, and unveil the underlying molecular mechanisms. A murine burn/tenotomy model was established to mimic trauma-induced HO in vivo. The anti-inflammation and anti-ossification effects of metformin were evaluated by histological staining and micro-CT. The inhibitory effects of metformin on macrophages activation in vitro were examined by ELISA and qRT-PCR. The underlying molecular mechanisms were further explored by immunofluorescence staining and western-blotting in vivo. Increased macrophages infiltration and inflammatory responses were found at early stage during HO progression. However, metformin dose-dependently attenuated the macrophage-mediated inflammatory responses both in vivo and vitro, which might account for the inhibitory effect of metformin on chondrogenesis and HO formation after trauma. Furthermore, elevated SIRT1 expression and decreased NF-κB p65 acetylation were found in the beneficial effects of metformin. Moreover, similar preventive effects were also found in SRT1720 HCI, a specific SIRT1 activator, while were remarkably reversed after the administration of EX527 (a specific SIRT1 inhibitor) with metformin. Taken together, our results provide a novel evidence that metformin can effectively attenuate trauma-induced HO by mitigating macrophage inflammatory responses through inhibiting NF-κB signaling via SIRT1-dependent mechanisms, which favors future therapeutic investigations for trauma-related disease.

Abstract
Heterotopic ossification (HO) is one of the most intractable disorders following musculoskeletal injury and is characterized by the ectopic presence of bone tissue in the soft tissue leading to severe loss of function in the extremities. Recent studies have indicated that immune cell infiltration and inflammation are involved in aberrant bone formation. In this study, we found increased monocyte/macrophage and mast cell accumulation during early HO progression. Macrophage depletion by clodronate liposomes and mast cell stabilization by cromolyn sodium significantly impeded HO formation. Therefore, we proposed that the dietary phytochemical quercetin could also suppress immune cell recruitment and related inflammatory responses to prevent HO. As expected, quercetin inhibited the monocyte-to-macrophage transition, macrophage polarization, and mast cell activation in vitro in a dose-dependent manner. Using a murine burn/tenotomy model, we also demonstrated that quercetin attenuated inflammatory responses and HO in vivo. Furthermore, elevated SIRT1 and decreased acetylated NFκB p65 expression were responsible for the mechanism of quercetin, and the beneficial effects of quercetin were reversed by the SIRT1 antagonist EX527 and mimicked by the SIRT agonist SRT1720. The findings in this study suggest that targeting monocyte/macrophage and mast cell activities may represent an attractive approach for therapeutic intervention of HO and that quercetin may serve as a promising therapeutic candidate for the treatment of trauma-induced HO by modulating SIRT1/NFκB signaling.

Abstract
BACKGROUND Pain, unrelated to the initial thermal trauma itself, can result after burn injury and prolong the recovery/rehabilitation phase of the patient's care. This pain, after discharge from the burn unit, may be acute and self-limiting or chronic and contribute to long-term patient morbidity. The purposes of this study were to compare burn patients who had, after discharge from the burn unit, only acute pain with burn patients who developed chronic, neuropathic pain (CNP) and to determine risks factors for progression from acute to chronic pain in the setting of a burn center. METHODS A single-center, retrospective chart review of patients admitted to the adult burn center was performed from January 1, 2014, to January 1, 2019. Patients included were older than 15 years, sustained a burn injury, and admitted to the burn unit. Chronic pain was defined as pain lasting greater than 6 months after discharge from the burn unit. Pain descriptors included shooting, stabbing, sharp, burning, tingling, numbness, throbbing, pruritus, intermittent, and/or continuous dysesthetic sensations after the burn. Patients were excluded if they had preexisting neuropathic pain due to an underlying medical illness or previous surgery. RESULTS During a 5-year period, of the 1880 admissions to the burn unit, 143 burn patients developed post-initial-onset pain as a direct result of their burn. Of the 143 patients with acute pain, pain resolved in 30 patients, whereas pain progressed to CNP in 113 patients (79%). Patient follow-up was a median (interquartile range [IQR]) of 26.5 (10-45) months. Patients whose pain progressed to CNP had significantly greater percent total body surface area burns (median [IQR], 6 [3-25] vs 3 [1-10]; P = 0.032), had more full-thickness burns (66/113 [58%] vs 8/30 [27%] patients, P = 0.004), had surgery (85/113 [75%] vs 16/30 [53%] patients, P = 0.042), had more surgical procedures (median [IQR], 2 [1-6] vs 1 [0-3], P = 0.002), and developed more complications (32/113 [28%] vs 2/30 [7%] patients, P = 0.014) compared with those with acute neuropathic pain, respectively. CONCLUSIONS Burn patients who progressed from having acute to CNP had significantly greater percent total body surface area burns, had more full-thickness burns, had surgery, had more surgical procedures, and developed more complications compared with burn patients with only acute pain.

Abstract
Monteggia lesions and Monteggia-like lesions involve ulna and radius injuries, which can not be successfully treated using the surgical principles of isolated fractures. Proximal ulnar fracture, radio-humeral dislocation, and additional dislocation in the proximal radioulnar joint result in the disintegration of the functional unit, and there is a complex injury across the elbow to the forearm, resulting in poor clinical outcomes. Thus, addressing all osteo-ligamentous injuries is essential for the long-term course.

Abstract
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.

Abstract
Background Heterotopic ossification (HO) formation after complex elbow injuries can significantly impact function. Prior studies have reported a 3%-45% incidence of HO following elbow trauma in a heterogeneous cohort of fracture patterns. The purpose of our study was to evaluate the prevalence of and identify risk factors for HO specifically in patients with terrible triad injuries. Methods A total of 61 patients (64 elbows) underwent operative treatment for terrible triad injuries with an average follow-up period of 19.8 months (range, 3-138 months). The medical records were reviewed for demographic data, duration of dislocation, number of reduction attempts, time to surgery, presence of radiographic HO, elbow motion at final follow-up, functional limitations, and need for secondary procedures. Results Radiographic HO developed in 77% of patients, and 63% had some level of functional restriction. Thirteen patients (26%) underwent a secondary procedure for HO excision. Patients with HO had a longer time to surgery (4.9 days vs. 2.8 days, P = .02), longer duration of dislocation (21 hours vs. 6 hours, P = .04), and reduced flexion-extension (94° vs. 112°, P = .04) and pronation-supination (109° vs. 163°, P = .002) arcs of motion compared with patients without HO. HO was also more likely to develop in patients who required closed reduction than in those with spontaneous reduction prior to presentation. Conclusion The prevalence of radiographic and clinically relevant HO after terrible triad injuries was higher than previously reported. Persistent dislocation necessitating a closed reduction, a longer duration of dislocation, and a delay to surgery were associated with the development of HO. Providers should consider earlier surgical stabilization or urgent referral to a specialist for patients with unstable injuries.

Abstract
AIMS Heterotopic ossification (HO) is a potentially devastating complication of the surgical treatment of a proximal humeral fracture. The literature on the rate and risk factors for the development of HO under these circumstances is lacking. The aim of this study was to determine the incidence and risk factors for the development of HO in these patients. METHODS A retrospective analysis of 170 patients who underwent operative treatment for a proximal humeral fracture between 2005 and 2016, in a single institution, was undertaken. The mean follow-up was 18.2 months (1.5 to 140). The presence of HO was identified on follow-up radiographs. RESULTS The incidence of HO was 15% (n = 26). Our multivariate model revealed that male sex (odds ratio (OR) 3.57, 95% confidence interval (CI) 1.30 to 9.80 compared to female) and dislocation as the initial injury (OR 5.01, 95% CI 1.31 to 19.22) were significantly associated with the formation of HO (p < 0.05) while no significant associations were seen for the age of the patient, the characteristics of the injury, or the type of operative treatment. CONCLUSION This retrospective radiological study is the first to investigate the association between the method of surgical treatment for a proximal humeral fracture and the formation of HO postoperatively. We found that male sex and dislocation as the initial injury were risk factors for HO formation, whereas the method of surgical treatment, the age of the patient, and the pattern of the fracture were not predictive of HO formation. While additional studies are needed, these findings can help to identify those at an increased risk for HO formation under these circumstances. Cite this article: Bone Joint J 2020;102-B(4):539-544.

Abstract
Heterotopic ossification is formation of bone in atypical extra-skeletal tissues and usually occurs spontaneously or following neurologic injury with unknown cause. We report a 46-year-old female with right shoulder pain and restricted range of motion (ROM) for 3 months without history of trauma. Magnetic resonance imaging (MRI) showed a lesion within the rotator cuff supraglenoid. Excisional biopsy from a previous institution revealed a heterotopic ossificans (HO ). Following repeat MRI and bone scan, histopathology from arthroscopic resection confirmed an HO. The patient demonstrated improved pain and ROM at follow-up. Idiopathic HO rarely occurs in the shoulder joint, and resection of HO should be delayed until maturation of the lesion to avoid recurrence. The current case showed that arthroscopic HO resection provides an excellent surgical view to ensure complete lesion removal and minimize soft tissue damage at the supraglenoid area. Furthermore, the minimally invasive procedure of arthroscopy may reduce rehabilitation time and facilitate early return to work.

Abstract
PURPOSE To analyze the complications of arthroscopic heterotopic ossification (HO) excision and compare them with those of open removal of HO or a combined open-arthroscopic approach. METHODS We performed a retrospective review of elbow HO removal cases performed by a single surgeon from 1997 to 2014. In all cases studied, the intention was to restore range of motion owing to the presence of HO causing functional impairment. The arthroscopic, open, and combined treatment groups were compared. RESULTS The study cohort consisted of 223 surgical procedures performed on 213 elbows in 211 patients. Fifty major complications occurred in 46 cases (21%): 17 hematomas (8%) treated by irrigation and debridement, 8 cases of HO requiring reoperation (4%), 7 deep infections (3%), 4 contractures (2%), 3 cases of delayed-onset ulnar neuritis (1%), 2 cases of distal humeral avascular necrosis (1%), 2 tendon ruptures (1%), 2 cases of instability requiring reconstruction (1%), 2 postoperative fractures (1%), 1 intraoperative fracture (<0.5%), 1 case of worsening of pre-existing neuropathic pain (<0.5%), and 1 permanent partial posterior interosseous nerve injury (<0.5%). Of these 46 cases, the major complications occurred in 6 of the 41 (15%) performed arthroscopically, in 36 of the 158 (23%) performed open and in 4 of the 21 (17%) with combined (i.e. open + arthroscopic) HO removal. Preventive strategies, introduced to prevent hematomas and delayed-onset ulnar neuritis, reduced the rate of major complications from 35% during the period from 1997 to 2005 to 10% during the period from 2006 to 2014 (P < .0001). Moreover, the rate of reoperations was reduced from 34% to 10% in the same periods (P < .0001). Minor complications occurred in 36 cases (16%), including 17 cases of transient nerve palsy, 9 cases of superficial infection or delayed wound healing, 6 cases of mild instability, and 4 cases of hematoma resolved by aspiration. CONCLUSIONS The use of arthroscopy-or a combination of arthroscopic and open techniques-to remove HO around the elbow by a surgeon skilled in both arthroscopic and open elbow surgery does not increase the risk of major complications or need for reoperation compared with traditional open surgery. Preventive strategies, such as avoiding raising skin flaps by using multiple separate incisions for open and prophylactic ulnar nerve decompression in arthroscopic cases, were developed during the study period. These strategies were monitored prospectively and found to be effective in preventing two-thirds of the major complications needing reoperation with both open and arthroscopic HO removal. LEVEL OF EVIDENCE Level III, retrospective comparative study of prospectively collected data.

Abstract
BACKGROUND Heterotopic ossification (HO) is a kind of abnormal mineralized bone which usually occurs in muscle, tendon, or ligament. There are currently no effective drugs for the treatment and prevention of HO. Developing effective drugs that can inhibit HO is of profound significance and would provide new strategies for clinical treatment of this disease. The present investigation evaluated the inhibitory effect of tamoxifen against HO. MATERIAL AND METHODS Using an Achilles tendon trauma-induced HO female mice model, we screened different doses of tamoxifen (1, 3, and 9 mg/kg) in mice to determine the optimal dosage on the inhibition of the HO formation. The curative effect of tamoxifen was also illustrated at different HO progression stages including inflammation, chondrogenesis, osteogenesis, and HO maturation. RESULTS Heterotopic bone was formed with typical endochondral ossification in Achilles tendons 6 weeks after surgery and continued to enlarge up to 12 weeks. The formation of HO was significantly inhibited with the treatment of tamoxifen at the dosage of 9 mg/kg, whereas 1 mg/kg and 3 mg/kg did not reduce HO bone volume remarkably. The progression of HO was both attenuated by tamoxifen from Day 1 and Week 4 post-surgery, whereas no inhibitory effect was shown at the osteogenesis and maturation stages treated with tamoxifen. CONCLUSIONS Tamoxifen exerts an inhibitory effect on the heterotopic bone progression at inflammation and chondrogenesis stages, with the TGF-ß signaling pathway suppressed following the increase in estrogen receptor alpha activity.

Abstract
The incidence of heterotopic ossification in adolescents appears to be lower than in adults. There exist very few reports of heterotopic ossification with total bony ankylosis in child or adolescent populations. We describe a case of total bony ankylosis of the elbow secondary to heterotopic ossification, in a 14-year-old female. Total ankylosis of the elbow at 45 degrees of flexion was noted 6 months post-surgery, and complete surgical excision of the heterotopic mass was performed. After an additional one-time dose of radiation therapy and nonsteroidal anti-inflammatory drug medication, full range of motion was obtained without any recurrence or other complications, up to the last follow-up of 30 months.

Abstract
Upper motor neuron disease or injury can lead to muscle spasticity or nonfunction throughout the body. Imbalance in muscle forces predisposes patients to development of functional deficiencies, contractures, pain, and poor hygiene. The approach to neuro-orthopaedic patients is by necessity multidisciplinary, because a variety of nonsurgical and surgical options are available. In evaluating each patient, surgeons must consider the extent and quality of any deformity, potential for improvement in function, the ability to alleviate pain, and potential for improvement in hygiene and cosmesis. Surgical techniques include tendon lengthenings, releases, transfers, osteotomies, and bony fusions.

Abstract
BACKGROUND Ulnar collateral ligament (UCL) reconstruction has become increasingly popular in elite athletes. However, the prevalence of heterotopic ossification (HO) formation after UCL reconstruction has not yet been reported. We sought to determine the prevalence of HO formation after UCL reconstruction and the clinical outcomes following HO treatment. MATERIALS AND METHODS From October 2005 to April 2014, 179 patients underwent primary UCL reconstruction. Of the 179 patients, 161 with a minimum of 2 years of follow-up were retrospectively reviewed to evaluate HO formation and clinical outcomes. RESULTS Among 161 patients, HO was detected in 8 cases (5%). Of these 8 patients, 2 were asymptomatic and another 2 complained about transient ulnar neuropathy. The remaining 4 patients had pain; 2 were treated with open excision, and 1 underwent arthroscopic excision. The odds of HO in patients in whom transient ulnar neuropathy develops after UCL reconstruction are 6 times higher than those without transient ulnar neuropathy (odds ratio, 5.957; 95% confidence level, P = .04). Of the 8 patients, 7 returned to the same level or a higher level of competition. HO was found, on average, 5 months (range, 3-9 months) after UCL reconstruction. CONCLUSION The prevalence of HO formation was approximately 5% after UCL reconstruction and increased with transient ulnar neuropathy. After UCL reconstruction, the surgeon should carefully observe HO formation, especially in the early stages after the operation. With appropriate treatment, the clinical outcomes of HO treatment after UCL reconstruction are favorable.

Influence of graft source and configuration on revision rate and patient-reported outcomes after MPFL reconstruction: a systematic review and meta-analysis. Knee Surg Sports Traumatol Arthrosc 2017; 25:2511-2519.

Abstract
PURPOSE The purpose of this systematic review and meta-analysis was to determine the influence of graft source (allograft vs. autograft) and configuration (single-limbed vs. double-limbed) on failure rate and disease-specific patient-reported outcome (Kujala score) after medial patellofemoral ligament (MPFL) reconstruction for patellar instability. METHODS A systematic review of PubMed, Scopus, and the Cochrane Library was performed. A total of 31 studies met inclusion/exclusion criteria and were used to extract cohorts of patients who underwent ligament reconstruction with various allograft, autograft, single-limbed, and double-limbed constructs. Failure rates and postoperative improvements in Kujala scores were compared between cohorts using inverse-variance weighting in a random-effects analysis model and appropriate comparative statistical analyses (Chi-squared and independent samples t tests). RESULTS A total of 1065 MPFL reconstructions were identified in 31 studies. Autograft reconstructions were associated with greater postoperative improvements in Kujala scores when compared to allograft (32.2 vs. 22.5, p < 0.001), but there was no difference in recurrent instability (5.7 vs. 6.7 %, p = 0.74). Double-limbed reconstructions were associated with both improved postoperative Kujala scores (37.8 vs. 31.6, p < 0.001) and lower failure rate (10.6 vs. 5.5 %, p = 0.030). CONCLUSION MPFL reconstructions should be performed using double-limbed graft configurations. While autograft tendon may be associated with higher patient-reported outcomes in the absence of associated connective tissue disorders or ligamentous laxity, patient factors and allograft processing techniques should be carefully considered when selecting an MPFL graft source, as revision rates were no different between graft sources.

Abstract
OBJECTIVE The objective of this study was to determine the contribution of lymphatic tissue to heterotopic ossification (HO). BACKGROUND HO is the pathologic development of ectopic bone within soft tissues often following severe trauma. Characterization of the tissue niche supporting HO is critical to identifying therapies directed against this condition. Lymphangiogenesis is upregulated during incidents of trauma, thereby coincident with the niche supportive of HO. We hypothesized that lymphatic tissues play a critical role in HO formation. METHODS Mice underwent hindlimb Achilles' tendon transection and dorsal burn injury (burn/tenotomy) to induce HO. The popliteal and inguinal lymph nodes were excised ipsilateral to the tenotomy site. Flow cytometry and immunostaining were used to quantify and localize lymphoendothelium. MicroCT was used to quantify HO. RESULTS Enrichment of mature lymphatic tissues was noted 2 weeks after injury at the tendon transection sites when compared with the contralateral, intact tendon based on LYVE1+ tubules (10.9% vs 0.8%, P < 0.05). Excision of the inguinal and popliteal nodes with draining popliteal lymphatic vessel significantly decreased the presence of mature lymphoendothelium 2 weeks after injury (10.9% vs 3.3%, P < 0.05). Bone-cartilage-stromal progenitor cells (CD105+/AlphaV+/Tie2-/CD45-/CD90-/BP1-) were also significantly decreased after lymph node excision (10.2% vs 0.5%, P < 0.05). A significant decrease was noted in the volume of de novo HO present within the soft tissues (0.12 mm vs 0.02 mm). CONCLUSION These findings suggest that lymphatic vessels are intimately linked with the de novo formation bone within soft tissues following trauma, and their presence may facilitate bone formation.

Abstract
Postburn contractures of the elbow are uncommon debilitating sequelae of severe burn injuries, which result from thermal injury to both deep and superficial tissues. When periarticular heterotopic bone forms in association with burn injuries, severe and rigid contractures may develop that prohibit basic functions of daily living and are often refractory to nonoperative intervention. Surgical intervention is aimed at releasing or excising all pathologic anatomy limiting elbow motion. In patients with proper indications, surgical intervention can result in substantial improvement in elbow motion, allowing patients to return to activities of daily living, employment, and recreational activities.

Abstract
Heterotopic ossification (HO) presents a substantial barrier to rehabilitation for patients with severe burns or trauma. Although surgical excision is a mainstay of management for this condition, this is unable to address the chronic sequelae of HO, including chronic pain, joint contractures, nerve dysfunction, and open wounds. Current therapeutic modalities are aimed at excision and the prevention of recurrence using nonsteroidal antiinflammatory drugs (NSAIDs) or radiation therapy. Research is now focused on identifying alternative strategies to prevent the initial occurrence of HO through NSAIDs and novel inhibitors of the bone morphogenetic protein signaling pathway.

Abstract
Introduction Treatment of heterotopic ossification (HO) of the elbow is challenging and fraught with complications. Patients who sustain direct trauma to the elbow joint, the central nervous system, and thermal burns are at increased risk for development of HO. There is a paucity of studies and reports on patient’s self-evaluation after the excision of the heterotopic ossification. Materials and Methods This retrospective study assessed outcomes after excision of heterotopic ossification around the elbow in a cohort of ten patients operated from 2012 to 2015. The outcome assessment was done by the Mayo Elbow Performance index (MEPI) and the American Shoulder and Elbow Surgeons-Elbow score (ASES-E scores). Results The mean follow-up was 18.11 months after the operation. The Mayo Elbow Performance Score was excellent in two elbows, good in six and fair in two. The mean gain in flexion-extension arc after excision of HO was 80 degrees. All of the patients had residual flexion deformity postoperatively. Eight of the nine patients were able to do activities requiring flexion at final follow-up. Conclusion Excision of HO around the elbow is associated with satisfactory patient-rated outcomes in spite of failure to regain full range of motion.

Abstract
Posttraumatic stiff elbow is a frequent and disabling complication and poses serious challenges for its management. In this review forty studies were included to know about the magnitude of the problem, causes, pathology, prevention, and treatment of posttraumatic stiff elbow. These studies show that simple measures such as internal fixation, immobilization in extension, and early motion of elbow joint are the most important steps that can prevent elbow stiffness. It also supports conservative treatment in selected cases. There are no clear guidelines about the choice between the numerous procedures described in literature. However, this review article disproves two major beliefs-heterotopic ossification is a bad prognostic feature, and passive mobilization of elbow causes elbow stiffness.

Abstract
Introducción y objetivos: Se entiende osificación heterotópica (OH) como la formación ectópica de hueso maduro en los tejidos blandos adyacentes a zonas previamente lesionadas. La OH es una de las causas de rigidez articular del codo postraumática, con una prevalencia que oscila según series entre el 3 y el 45%. En su patogénesis se postula la diferenciación de células mesenquimales pluripotenciales en osteoblastos, siendo estos los causantes de la formación de hueso ectópico; sin embargo, se desconocen las causas que provocan esta reacción. Recientemente, diversos estudios de series de casos retrospectivos mediante análisis uni y multivariante han intentado encontrar factores de riesgo (FR) y parámetros predictores de la formación de OH, así como de su repercusión clínica.Material y métodos: Presentamos un análisis retrospectivo de los casos de OH en codo tratados quirúrgicamente en nuestro centro entre los años 2005 y 2015. Se recogieron variables demográficas, antecedentes personales, evento traumático inicial, clínica, tiempo desde el traumatismo hasta el diagnóstico de la OH, tiempo desde el diagnóstico de OH hasta la cirugía escisional, seguimiento, recurrencia, y grados de movilidad en precirugía escisional y al final del seguimiento. Con ello pretendemos mostrar nuestra experiencia en el tratamiento quirúrgico de esta patología.Resultados: Obtuvimos 4 casos con un tiempo medio de seguimiento de 40 meses. En 2 casos el evento traumático fue la luxación de codo, y en los otros 2, la ruptura del tendón del bíceps en su inserció n distal. Tres de ellos debutaron clínicamente con limitación en la movilidad articular, y uno con déficit motor a nivel radial. Todos los casos fueron varones con una edad media de 48 años. El tiempo medio transcurrido desde el evento traumático hasta el diagnóstico de OH fue de 4 meses, realizándose el tratamiento quirúrgico escisional tras el diagnóstico igualmente a los 4 meses aproximadamente como media. Tres de los 4 casos recidivaron, apareciendo nuevas calcificaciones con repercusión clínica y funcional.Conclusión: Nuestros resultados convergen con los de la literatura en cuanto a FR y resultados funcionales; sin embargo, llama la atención el alto índice de recidiva en nuestra serie, con una tasa del 75% frente al 10-24% descrito en la literatura.

Abstract
PURPOSE (1) To identify existing outcomes studies and (2) to use meta-analysis techniques to summarize pooled clinical outcomes for surgical techniques that decompress the bicipital tunnel and those that do not, to identify important areas for future clinical investigation. METHODS A systematic review of the PubMed database was performed in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. Patients were categorized into 2 groups for analysis. Group 1, the "tunnel decompressed" group, included open subpectoral tenodesis, long head of the biceps tendon transfer procedures, and proximal tenodesis techniques that explicitly released the bicipital sheath. Group 2, the "tunnel not decompressed" group, included proximal tenodesis techniques and tenotomy. Validated clinical outcome measures (Constant; University of California, Los Angeles; Simple Shoulder Test; visual analog scale for pain; and American Shoulder and Elbow Surgeons) and revision rates were summarized using inverse-variance weighting in a random-effects model. Because the constituent studies were largely single-cohort observational studies, direct between-group statistical comparisons could not be made. RESULTS Thirty studies (comprising 1,881 patients) met the inclusion and exclusion criteria. The Constant score was the most commonly reported outcome measure (16 cohorts, 961 patients) and was seemingly higher in group 1 (88.3 v 81.7). Revision rates; University of California, Los Angeles scores; Simple Shoulder Test scores; visual analog scale scores for pain; and American Shoulder and Elbow Surgeons scores appeared to be similar between groups. The mean patient age was 50.7 ± 5.7 years for group 1 and 58.9 ± 6.3 years for group 2. The Egger intercept method showed an intercept of -13.29 (P < .001) for the Constant score, indicating a high likelihood of publication bias in the included studies. CONCLUSIONS Bicipital tunnel-decompressing techniques showed apparently higher Constant scores compared with non-decompressing techniques but may have been affected by differences in mean patient age between groups. Existing literature consists of largely single-cohort retrospective observational Level IV studies, which are likely influenced by significant publication bias. LEVEL OF EVIDENCE Level IV, systematic review of Level II through IV studies.

Abstract
BACKGROUND Heterotopic ossification (HO) recurrence after joint surgery is always a disturbing problem for patients and surgeons. Our study was performed to assess the efficacy and safety of celecoxib in preventing the recurrence of HO after open arthrolysis for post-traumatic elbow stiffness. METHODS We retrospectively studied 152 patients with stiff elbows caused by post-traumatic HO. After surgery, 77 patients received celecoxib (200 mg once daily) for 28 days, whereas 75 did not. Radiographic evaluation was performed at 3, 6, and 9 months postoperatively. Univariate and multivariate analyses were performed to determine which factors affected HO recurrence. RESULTS HO was both more common and more severe in the no-celecoxib group than in the celecoxib group at 3, 6, and 9 months after surgery. A significant difference was observed between the 2 groups in terms of postoperative extension (P = .030), flexion (P = .008), and pronation (P = .005); however, no significant difference in postoperative supination was noted (P = .622). Logistic regression analysis showed that taking celecoxib was the protective factor for HO recurrence, whereas overweight (body mass index > 25) and male gender were the risk factors. CONCLUSIONS A short course of celecoxib aids in the prevention of HO recurrence after open arthrolysis for elbow stiffness in adults and could be an effective and safe option.

Abstract
BACKGROUND Heterotopic ossification (HO) is common after combat-related amputations and surgical excision remains the only definitive treatment for persistently symptomatic HO. There is no consensus in the literature regarding the timing of surgery, and recurrence frequency, reexcision, and complications have not been reported in large numbers of patients. QUESTIONS/PURPOSES (1) What are the rates of symptomatic recurrence resulting in reexcision and other complications resulting in reoperation in patients with HO? (2) Is either radiographic or symptomatic recurrence dependent on timing and type of initial surgery, the experience of the surgeon in performing the procedure, the severity of preexcision HO, the presence of concomitant neurologic injury, or the use of postoperative HO prophylaxis? METHODS Between March 2005 and March 2013 our institution treated 994 patients with 1377 combat-related major extremity amputations; of those, 172 amputations underwent subsequent excision of symptomatic HO. The mechanism of injury resulting in nearly all amputations (n = 168) was blast-related trauma. We reviewed medical records and radiographs to collect initial grade of HO, radiographic recurrence, complete compared with partial excision, concomitant neurologic injury, timing to initial surgery, surgeon experience, and use of postexcision prophylaxis with our primary study outcome being a return to the operating room (OR) for repeat excision of symptomatic HO. All 172 combat-related amputations were considered for this study irrespective of followup, which was noted to be robust, with 157 (91%) amputations having at least 6 months clinical followup by an orthopaedic surgeon or physiatrist (median, 20 months; range, 0-88 months). RESULTS Eleven of 172 patients (6.5%) underwent reexcision of HO, and 67 complications resulting in return to the OR occurred in 53 patients (31%) of patients. Multivariate analysis of our primary outcome measure showed more frequent symptomatic recurrences requiring reexcision when initial excision was performed as a partial excision (p = 0.03; odds ratio [OR], 5.0; 95% confidence interval [CI], 1.2-29.6) or when the initial excision was performed within 180 days of injury (p = 0.047; OR, 4.1; 95% CI, 1.02-16.6). There was no association between symptomatic recurrence and HO grade, central nervous system injury, experience of the attending surgeon, or postoperative prophylaxis. Radiographic recurrence was observed when partial excisions (eight of 30 [27%]) were done compared with complete excisions (five of 77 [7%]; p = 0.008). CONCLUSIONS HO is common after combat-related amputations, and patients undergoing surgical excision of HO for this indication often have complications that result in repeat surgical procedures. Partial excisions of immature lesions more often resulted in both symptomatic and radiographic recurrence. The likelihood of a patient undergoing reexcision can be minimized by performing a complete excision at least 180 days from injury to surgery with no evidence of a reduced risk of reexcision by waiting longer than 270 days. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
HYPOTHESIS This study evaluated the usefulness of computed tomography (CT) imaging for preoperative planning of heterotopic ossification (HO) excision, specifically the spatial relationship between HO and radial and median nerves. Our hypotheses were that CT imaging of the elbow can be used (1) to trace the paths of the radial and median nerves, (2) to distinguish the nerves from the heterotopic bone, and (3) to precisely measure distances from the respective nerve to the most clinically relevant HO. MATERIALS AND METHODS Patients who had HO removed from the elbow were reviewed retrospectively. On the basis of preoperative CT scans, 22 were identified as likely having HO along the pathway of the radial or median nerve. These cases were independently evaluated by 4 observers, who answered these questions: (1) Can the location of the nerve be adequately seen on sequential images to permit tracing of its path for surgical planning? (2) Can the nerve be distinguished from the HO accurately enough to permit measurement of its distance from the bone? Each observer also measured the shortest distance between nerves and the HO. RESULTS Overall utility of the CT images for visualizing the nerves was high. The radial nerve was more readily distinguished from the HO (21 of 22 cases) than the median nerve (17 of 22 cases). The distance measured from HO was less for the radial nerve (3 mm) than for the median nerve (9 mm). CONCLUSION This study demonstrates the usefulness of CT imaging to determine the paths of the radial and median nerves and their spatial relationship to HO at the elbow.

Abstract
➤ Heterotopic ossification occurs most commonly after joint arthroplasty, spinal cord injury, traumatic brain injury, blast trauma, elbow and acetabular fractures, and thermal injury.➤ The conversion of progenitor cells to osteogenic precursor cells as a result of cell-mediated interactions with the local tissue environment is affected by oxygen tension, pH, availability of micronutrients, and mechanical stimuli, and leads to heterotopic ossification.➤ Radiation and certain nonsteroidal anti-inflammatory medications are important methods of prophylaxis against heterotopic ossification.➤ Well-planned surgical excision can improve patient outcomes regardless of the joint involved or the initial cause of injury.➤ Future therapeutic strategies are focused on targeted inhibition of local factors and signaling pathways that catalyze ectopic bone formation.

Abstract
BACKGROUND Heterotopic ossification (HO) is a serious complication of traumatic elbow injuries, particularly fracture-dislocations. Limited data exist in the literature regarding the risk factors associated with HO formation in these injuries. The purpose of this study was to review the incidence of HO after fracture-dislocation of the elbow and to identify potential risk factors associated with its formation. METHODS Twenty-seven patients (28 elbows) were surgically treated for elbow fracture-dislocations during 8 years, with an average follow-up of 14 months. Records were reviewed with attention paid to several factors: demographic data, comorbidities, time interval from injury to surgical intervention, number of closed reductions attempted before surgery, surgical approach, management of the radial head, treatment of the anterior capsular injury, and coronoid fixation. RESULTS Of the 28 elbows, 12 (43%) developed HO postoperatively; 9 of 28 elbows underwent multiple attempted closed reductions before definitive surgical stabilization, with HO formation in 7 of the 9 (77%). Time to surgery, age, gender, radial head fixation or replacement, coronoid open reduction and internal fixation, capsular repair, and medical comorbidities were not found to influence HO formation, although the performance of multiple reductions was identified as a risk factor. DISCUSSION HO developed in 77% of patients with multiple attempted closed reductions. We found a 43% incidence of HO in patients surgically treated for elbow fracture-dislocations. Neither time to surgery after the injury nor demographic or other factors relating to the manner in which associated osseous or soft tissue injuries were managed influenced the formation of HO.

Abstract
BACKGROUND Heterotopic ossification is the most common extrinsic cause of elbow contracture and may lead to clinically important stiffness, and rarely, complete bony ankylosis. Surgery sometimes is performed to treat this problem, and published reports differ regarding the factors that are associated with success or failure after this operation and whether the procedure is effective for patients with elbow ankylosis. QUESTIONS/PURPOSES We wished (1) to identify potential patient characteristics and modifiable risk factors that are associated with improvements in ROM after surgery for heterotopic ossification of the elbow; (2) to compare ROM gains between patients with complete ankylosis and partially restricted ROM; and (3) to characterize the complications of elbows treated by surgical release and excision of heterotopic ossification followed by a standardized rehabilitation program. METHODS We reviewed the records of all patients treated operatively for heterotopic ossification of the elbow from September 1999 to February 2012 at one institution by one surgeon. General indications for the surgery were clinically symptomatic or debilitating heterotopic ossification of the elbow. Each patient received prophylaxis postoperatively consisting of indomethacin (or single-shot radiation for patients with sensitivity to antiinflammatory medications). All patients received a physical therapy regimen and used a continuous passive motion machine for 6 weeks. Patient demographics, mechanism of injury, time between injury and surgery, and medical history were reviewed for comparison. Followup was at a mean of 13 months (range, 3-106 months); no patients were lost to followup. Thirty-nine patients (46 elbows) with heterotopic ossification treated with excision were identified: 10 patients (16 elbows) had burns, 28 patients (29 elbows) had trauma, and one patient (one elbow) had a closed head injury. Eight of the 39 patients (12 of 46 elbows [26%]) had complete ankylosis at the time of surgery. RESULTS Hypertension, obesity, and absence of intraoperative anterior ulnar nerve transposition were associated with an adverse effect on change from preoperative to final arc of motion. The group with ankylosis had greater preoperative to postoperative gain in arc compared with the group with partial restriction (96°, 95% CI, 84°-107° and 59°, 95% CI, 46°-72°, respectively). For the entire cohort there was an overall improvement in mean flexion-extension arc of motion from 35° to 103° at final followup (p < 0.001; 95% CI, 57°-80°), with a 17% rate of complications (three patients [three elbows] with heterotopic ossification, three patients [three elbows] with nerve palsies, one patient [one elbow] with deep wound infection, and one patient [one elbow] with an unstable elbow). CONCLUSIONS Patients with partially and completely restricted ROM showed substantial improvement in postoperative ROM. Hypertension, obesity, and absence of intraoperative anterior ulnar nerve transposition were negative predictors of outcome in our series. Surgery combined with postoperative prophylaxis and a regimented rehabilitation program are feasible modalities to treat patients with heterotopic ossification of the elbow.

Abstract
Complex elbow trauma, severe burn, or a closed head injury render patients at risk for developing heterotopic ossification around the elbow. When heterotopic ossification restricts elbow motion, some patients request surgical resection. We performed a systematic review of the literature to analyze improvement in elbow motion after resection of heterotopic ossification around the elbow. We found that, on average, etiology had little impact on outcome after resection of heterotopic ossification. Resection of heterotopic bone generally leads to improvement of elbow function.
