Resection of Posttraumatic Rib Synostoses Resolves Pulmonary Insufficiency: A Case Report.

Case: A 30-year-old woman underwent open reduction and internal fixation for multiple segmental rib fractures status post a motor vehicle collision. A year later, the patient presented with extensive intercostal heterotopic ossification associated with multilevel, hemithoracic, rib synostoses compromising her ventilation. The patient subsequently underwent synostoses excision and hardware removal.

A new mouse model of post-traumatic joint injury allows to identify the contribution of Gli1+ mesenchymal progenitors in arthrofibrosis and acquired heterotopic endochondral ossification.

Complex injury and open reconstructive surgeries of the knee often lead to joint dysfunction that may alter the normal biomechanics of the joint. Two major complications that often arise are excessive deposition of fibrotic tissue and acquired heterotopic endochondral ossification. Knee arthrofibrosis is a fibrotic joint disorder where aberrant buildup of scar tissue and adhesions develop around the joint.

The Kinesin Gene Modulates the Severity of Post-Traumatic Heterotopic Ossification.

The formation of pathological bone deposits within soft tissues, termed heterotopic ossification (HO), is common after trauma. However, the severity of HO formation varies substantially between individuals, from relatively isolated small bone islands through to extensive soft tissue replacement by bone giving rise to debilitating symptoms. The aim of this study was to identify novel candidate therapeutic molecular targets for severe HO.

Treatment of Unstable Elbow Injuries with a Hinged Elbow Fixator: Subjective and Objective Results.

Introduction: Injuries around the elbow pose a challenging problem for orthopaedic surgeons. The complex bony architecture of the joint should be restored and the thin soft tissue envelope needs to be handled with meticulous care. Elbow instability is a complication seen after dislocations and fractures of the elbow and remains a treatment challenge.

A new prognostic nomogram for heterotopic ossification formation after elbow trauma : the Shanghai post-Traumatic Elbow Heterotopic Ossification Prediction (STEHOP) model.

Aims: Heterotopic ossification (HO) is a common complication after elbow trauma and can cause severe upper limb disability. Although multiple prognostic factors have been reported to be associated with the development of post-traumatic HO, no model has yet been able to combine these predictors more succinctly to convey prognostic information and medical measures to patients. Therefore, this study aimed to identify prognostic factors leading to the formation of HO after surgery for elbow trauma, and to establish and validate a nomogram to predict the probability of HO formation in such particular injuries.

Neurogenic Heterotopic Ossification of the Hip after Brain Injury. Function Recovery Preserving Hip Joint: A Case Report.

Introduction: Up to 30% of patients with spinal cord injury and to 20% of patients with traumatic brain injury develop neurogenic heterotopic ossification (NHO). Patients develop restriction in joint range of motion (ROM) and impairment in activities of daily life. When neurological recovery occurs, joints dysfunction represents the cause for patients' autonomy loss.

The survivorship and factors affecting the outcome of the use of spring plates in multifragmentary posterior wall acetabular fractures at a single academic institution.

Background: Multifragmentary posterior wall fractures are not uncommon after posterior hip fracture-dislocation. They can be elementary but are commonly associated with transverse acetabular fractures. Specific technical challenges are encountered when managing these fracture patterns.

Does an Internal Joint Stabilizer and Standardized Protocol Prevent Recurrent Instability in Complex Persistent Elbow Instability?

Background: The treatment of complex persistent elbow instability after trauma is challenging. Previous studies on treatments have reported varied surgical techniques, which makes it difficult to establish a therapeutic algorithm. Furthermore, the surgical procedures may not sufficiently restore elbow stability, even with an additional device, and a noted high rate of arthritis progression.

The MFA includes survey of daily activities, gross and fine mobility, social and work function, sleeping, and mood.

Heterotopic Ossification Complicating Traumatic Ulnar Nerve Palsy in a Child.

Heterotopic ossification (HO) refers to the process of forming bony tissues in extra-skeletal sites such as muscles and soft tissues. This pathological process most commonly commences following trauma, surgery, and fractures. Rarely, HO can compress nearby neurovascular structures.

Long-Term Functional Outcomes and Complications of Intra-Articular (AO type B, C) Distal Humerus Fractures in Adults: A Retrospective Review.

Introduction Treatment of intra-articular fractures of the distal humerus is challenging due to their complexity, comminution, and associated complications. The evolution of surgical approaches and the design of elbow-specific implants over the last decades have failed to improve clinical and radiological outcomes. Studies are sparse regarding the long-term influence of surgical treatment of these types of fractures in the upper limb function.

[Radial head arthropolasty in unreconstructable comminuted fractures of the radial head: Long-term results and factors influencing the outcome].

Background: Radial head arthroplasty is recognized as the gold standard in the treatment of patients with unreconstructable radial head fractures.

Objective: The aim of this retrospective study was to investigate the long-term results after prosthetic replacement of the radial head and in a subgroup analysis to identify factors which influence the outcome.

Material And Methods: A total of 48 patients with unreconstructable fractures of the radial head and neck were treated by cementless radial head arthroplasty between 05/2008 and 10/2018 (30 bipolar prosthesis type rHead Recon, 18 monopolar prosthesis type MoPyc).

Poly(lactic acid-co-glycolic acid)-based celecoxib extended-release microspheres for the local treatment of traumatic heterotopic ossification.

Traumatic heterotopic ossification (THO) is a serious and common clinical post-traumatic complication for which there is no effective and safe drug treatment. Routine administration of nonsteroidal anti-inflammatory drugs (NSAIDs) after injury is extensively used approach for THO. However, serious adverse events can occur in the event of an overdose of NSAIDs.

Methods: We retrospectively analysed 60 THA (21 aTHA; 39 dTHA) performed for acetabular fracture between 2004 and 2014 in 60 patients with a mean age of 59 years (20-94).

Heterotopic Ossifications after Fractures of the Anterior Pelvic Segment: Overview of Morphology and Clinical Correlations.

PURPOSE OF THE STUDY In certain patients after treated pelvic fractures, heterotopic ossifications can be observed in the area of the pubic bone, which protrude ventrally, and often also laterally and distally into surrounding soft tissues of the groin or even medially into the proximal thigh. These ossifications are shaped like sharp spikes of various lengths, which is why the authors refer to them as "spicules". In some patients, these ossifications are also associated with pain.

Safety and efficacy of surgical hip dislocation in managing femoral head fractures: A systematic review and meta-analysis.

Background: Femoral head fractures (FHFs) are considered relatively uncommon injuries; however, open reduction and internal fixation is preferred for most displaced fractures. Several surgical approaches had been utilized with controversial results; surgical hip dislocation (SHD) is among these approaches, with the reputation of being demanding and leading to higher complication rates.

Aim: To determine the efficacy and safety of SHD in managing FHFs by reviewing the results reported in the literature.

Clinical outcomes of reverse total shoulder arthroplasty for elective indications versus acute 3- and 4-part proximal humeral fractures: a systematic review and meta-analysis.

Background: Reverse total shoulder arthroplasty (RTSA) has continued to increase in clinical utility and popularity as an effective treatment for cuff tear arthropathy (CTA), irreparable rotator cuff tears (RCTs), osteoarthritis, and acute 3- and 4-part proximal humeral fractures. Performing RTSA for acute proximal humeral fractures presents the unique challenges of tuberosity management, bone loss, and instability compared with elective indications such as CTA or irreparable RCTs. The purpose of this study was to compare the clinical outcomes, active range of motion (ROM), radiographic outcomes, and complications between patients undergoing elective RTSA (RTSA-E) and those undergoing RTSA for fracture (RTSA-F).
