The authors report on the first surgical treatment for traumatic interspinous ligament calcification, with significant radiographic and symptomatic improvements at long-term follow-up. Heterotopic ossification occurs following traumatic injury but does not typically affect the interspinous ligaments. While these ligaments can calcify with age, this is rarely seen in patients younger than 50 years of age. Read More

Background: Although simple posterolateral or posterior elbow dislocations are relatively common and usually stable after closed reduction, simple posteromedial dislocations are extremely rare and poorly characterized. We investigated the clinical characteristics, soft-tissue injury patterns, treatments, and outcomes of a series of posteromedial elbow dislocations without relevant osseous lesions.

Methods: We retrospectively reviewed 20 cases of simple posteromedial elbow dislocations without relevant osseous lesions that were treated at 7 fellowship training hospitals during a 10-year period. Read More

Heterotopic ossification can be defined as the formation of bone in tissues that have no ossification properties, such as in muscles and connective tissue of a periarticular region, without invasion of the joint capsule. This pathology usually has a benign course, but it can cause a reduction in the range of joint movement and hamper the rehabilitation process. Its etiology is still unknown and it usually is originated from posttraumatic complications, affecting 10-20% of patients with traumatic brain injury. Read More

Introduction: Posttraumatic heterotopic ossification (HO) of the hip frequently follows acetabular fracture and hip surgery and can become symptomatic, with significant pain and limited range of motion (ROM). Definitive treatment may require surgical excision, which can result in serious complications if not planned and executed appropriately.

Methods: Surgical excision of posttraumatic hip HO requires appropriate indications, preoperative planning, and intraoperative guidance using fluoroscopy to maximize excision of HO and minimize complications. Read More

Proximal radioulnar synostosis is a rare but highly disabling posttraumatic complication in periarticular elbow injuries. Surgical treatment is an option for functionally limiting proximal radioulnar synostosis; however, the approach can endanger local neurovascular structures, especially if the synostosis affects the level of the bicipital tuberosity. We report two cases of proximal radioulnar synostosis with a preoperative prono-supination range of motion of 0° and 15° treated by a reverse Sauvé-Kapandji procedure resecting a 1-cm section of the radial shaft distal to the bicipital tuberosity and leaving the synostosis in place.

Heterotopic ossification (HO) is a clinical condition that often reduces mobility and diminishes quality of life for affected individuals. The most severe form of progressive HO occurs in those with fibrodysplasia ossificans progressiva (FOP; OMIM #135100), a genetic disorder caused by a recurrent heterozygous gain-of-function mutation (R206H) in the bone morphogenetic protein (BMP) type I receptor ACVR1/ALK2. In individuals with FOP, episodes of HO frequently follow injury. Read More

Department of Medicine, Mayo Clinic School of Medicine, Mayo Clinic, Rochester, MN, United States. Electronic address:

Background: Episodic flare-ups of fibrodysplasia ossificans progressiva (FOP) are characterized clinically by severe, often posttraumatic, connective tissue swelling and intramuscular edema, followed histologically by an intense and highly angiogenic fibroproliferative reaction. This early inflammatory and angiogenic fibroproliferative response is accompanied by the presence of abundant mast cells far in excess of other reported myopathies.

Results: Using an injury-induced, constitutively-active transgenic mouse model of FOP we show that mast cell inhibition by cromolyn, but not aprepitant, results in a dramatic reduction of heterotopic ossification. Read More

Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disease with a progressive course characterized by episodically local flare-ups, which often but not always leads to heterotopic bone formation (HO). Recently, we showed that [18F]NaF PET/CT may be the first tool to monitor progression of a posttraumatic flare-up leading to new HO, which was demonstrated in a patient with FOP who underwent a maxillofacial surgery. This paper evaluates [18F]NaF PET/CT as a marker of FOP disease activity, comparing its use with other imaging modalities known in literature. Read More

Heterotopic ossification (HO) can result from a single severe injury, repeated microtrauma, central nervous system injury, extensive burns, or muscular bleeding due to hemophilia. Although relatively rare in childhood and extremely rare within a joint, HO should be included in the differential diagnosis of an intra-articular mass when indicated by clinical, radiographic, and histologic findings. Here, we report a posttraumatic intra-articular HO of the shoulder joint in a 15-month-old boy without underlying hematologic disease. Read More

The elbow is a highly congruent trochoginglymoid joint allowing motion in both flexion-extension and pronosupination across 3 articulations. Therefore, treatment of fractures of the elbow can be technically challenging to manage, even after initial surgery. The posttraumatic elbow is prone to complications such as stiffness associated with heterotopic ossification, instability or subluxation (posterolateral rotatory instability and varus posteromedial instability patterns), and wound complications.

Clin Orthop Relat Res 2016 Feb;474(2):392-8

Division of Orthopaedic Surgery, Department of Surgery, St Michael's Hospital, Toronto, ON, Canada.

Background: Despite modern fracture management techniques allowing for near anatomic reduction of acetabular fractures, there continues to be a risk of posttraumatic arthritis and need for total hip arthroplasty (THA). Few well-controlled studies have compared THA after acetabular fractures with THAs performed for other indications in terms of survivorship or complications, and none, to our knowledge, present 10-year survivorship data in this setting.

Questions/purposes: (1) How does the 10-year survival of THA compare between those patients who underwent THA after an acetabular fracture and those who underwent THA for primary arthritis or avascular necrosis (AVN)? (2) Is there an increased risk of serious complications like infection, dislocation, and aseptic loosening as well as heterotopic ossification associated with a THA performed after a previous acetabular fracture?

Methods: This retrospective case-control study compared findings of patients who underwent THA after acetabular fracture versus a matched cohort of patients who had received a primary THA for primary osteoarthritis or AVN. Read More

Introduction: Injuries to the distal tibiofibular syndesmosis are frequent and continue to generate controversy.

Methods: The majority of purely ligamentous injuries ("high ankle sprains") is not sassociated with a latent or frank tibiofibular diastasis and may be treated with an extended protocol of physical therapy. Relevant instability of the syndesmosis with diastasis results from rupture of two or more ligaments that require surgical stabilization. Read More

Clin Orthop Relat Res 2015 Dec;473(12):3744-51

Department of Orthopaedic Surgery, University of Berne, Berne, Switzerland.

Background: Femoral head fractures are rare injuries; incongruency and instability are indications for surgical intervention. Anterior, posterior, and transtrochanteric surgical approaches have been proposed, but the exposure is limited with classical approaches. Surgical hip dislocation allows for a 360° view of the head and may facilitate a reduction in selected head fractures, but to our knowledge, few studies have reported on the results with this technique.

Background: The "terrible triad" of the elbow is a complex injury that can lead to pain, stiffness, and posttraumatic arthritis if not appropriately treated. The primary goal of surgery for these injuries is to restore stability of the joint sufficient to permit early motion. Although most reports recommend repair and/or replacement of all coronoid and radial head fractures when possible, a recent cadaveric study demonstrated that type II coronoid fractures are stable unless the radial head is removed and not replaced.
