Background Management of tibial fractures associated with soft tissue injury remains controversial. Previous studies have assessed perfusion of the fractured tibia and surrounding soft tissues in the setting of a normal soft tissue envelope. The purpose of this study was to determine the effects of muscle contusion on blood flow to the tibial cortex and muscle during reamed, intramedullary nailing of a tibial fracture. Methods Eleven adult canines were distributed into two groups, Contusion or No-Contusion. The left tibia of each canine underwent segmental osteotomy followed by limited reaming and locked intramedullary nailing. Six of the 11 canines had the anterior muscle compartment contused in a standardized fashion. Laser doppler flowmetry was used to measure cortical bone and muscle perfusion during the index procedure and at 11 weeks post-operatively. Results Following a standardized contusion, muscle perfusion in the Contusion group was higher compared to the No-Contusion group at post-osteotomy and post-reaming (p < 0.05). Bone perfusion decreased to a larger extent in the Contusion group compared to the No-Contusion group following osteotomy (p < 0.05), and the difference in bone perfusion between the two groups remained significant throughout the entire procedure (p < 0.05). At 11 weeks, muscle perfusion was similar in both groups (p > 0.05). There was a sustained decrease in overall bone perfusion in the Contusion group at 11 weeks, compared to the No-Contusion group (p < 0.05). Conclusions Injury to the soft tissue envelope may have some deleterious effects on intraosseous circulation. This could have some influence on the fixation method for tibia fractures linked with significant soft tissue injury.

Background: With high energy fractures to the calcaneus there is the potential for significant bone loss. The loss of bone can make it difficult to fully regain calcaneal alignment. In addition these fractures are often associated with significant soft tissue injury. These two factors make it difficult to address this injury in a single stage, and can have significant complications. To address these issues our initial goal in treatment has been restoration of calcaneal alignment and stabilization of the surrounding soft tissue, followed by delayed/staged subtalar arthrodesis. Methods: Patients with calcaneus fractures treated by a single surgeon from 2002 to 2012 were reviewed. Injuries which were found to have medial extrusion of the posterior facet and bone loss, and subsequently underwent a staged protocol involving early provisional fixation and late subtalar fusion were included. Results: We treated 6 calcaneus fractures with bone loss. All patients were treated with staged subtalar fusion after initial irrigation and debridement and provisional fixation. No soft-tissue complications were noted after the fusion procedure in any of the six cases. Fusion occurred in all six patients at an average of 20.6 weeks (range, 13-23 weeks). All patients were able to ambulate and wear a regular shoe by one year following the initial injury. Conclusion: It is important in the high energy calcaneus fracture to assess for both soft tissue integrity and bone loss. A thorough debridement of both the soft tissues and any devitalized bone should be performed as well as provisional fixation which attempts to restore near normal calcaneal anatomy. Definitive fusion should not be performed until the soft tissues have fully recovered.

Background: The soft tissues injury in periarticular fractures of the lower extremities determines the proper time to perform bone fixation. Objetive: The aim of this study was to determine the intra and interobserver agreement in the Tscherne classification. Methods: This is a descriptive, prospective study for patients admitted to the Pablo Tobón Uribe Hospital (PTUH) with tibial plateau or tibial pilon fractures. We performed a standardize evaluation using video photography at the time of admission and 24, 48, and 72 h after admission. Fifteen five reviewers who had various levels of training produced a total of 1,200 observations. The intra- and interobserver agreement was assessed using a weighted kappa for multiple raters and more than two categories. Results: Twenty patients were admitted with tibial plateau and tibial pilon fractures. The intraobserver agreement for all 15 raters was kappa 0.81 (95% CI 0.79-0.83), and the interobserver agreement for all 15 raters was kappa 0.65 (95% CI 0.55-0.73). The interobserver agreement at 24 h was kappa 0.67 (95% CI 0.46-0.86). Conclusions:Classifying the severity of soft tissue injury is critical in planning the surgical management of fractures of the lower extremities. Based on our results, we can reasonably argue that the Tscherne classification produced an adequate level of agreement and could be used to standardize and to guide the treatment, and to conduct research studies. Level of Evidence: Level IV, Case Series

Background: Tibiotalocalcaneal (TTC) intramedullary nailing has been suggested as an alternative to open reduction and internal fixation (ORIF) for the primary treatment of unstable fragility ankle fractures with a poor soft tissue envelope. This study aims to investigate the clinical efficacy of TTC intramedullary nail fixation for the primary treatment of unstable ankle fractures in frail elderly patients with poor soft tissue condition, by assessing the number of postoperative complications and the patient-reported functional outcomes. Methods: A retrospective cohort study was performed including patients with an unstable ankle fracture treated between 2015 and 2019 with TTC stabilization using a retrograde intramedullary hindfoot nail that was inserted without joint preparation and allowing immediate weight-bearing postoperatively. The primary outcome was the total number of postoperative complications. Results: A total of 10 patients were included out of 365 operatively treated ankle fractures. The mean age was 85.2 years (range 66-92) with a mean follow-up of 11.2 months (range 6-16). Fracture types included AO/OTA 44-B2 (n = 1), 44-B3 (n = 6), 44-C1 (n = 2) and 44-C3 (n = 1). Postoperative complications were observed in 4 patients (40%), including 3 nonunions, 2 implant related complications and 1 wound infection. No wound healing disorder or below-the-knee amputation was observed. Four patients (40%) deceased between post-operative 6 to 16 months due to medical conditions unrelated to surgery. The mean Foot and Ankle Outcome Score was 52.6 (range 44.2-73.8). Conclusion: Hindfoot nailingis a viable treatment option in selected high-risk patients with an advanced age, unstable ankle fractures with significant bone loss, poor soft tissue condition and/or severely impaired pre-injury mobility. In a frail geriatric population, hindfoot nailing may be a safe alternative fixation method with a low risk of wound complication or major amputation. However, unprepared joint may lead to symptomatic nonunion after TTC intramedullary nailing.

Sprain, strain and bruise are terms loosely used to denote injury of soft tissues. More precisely a sprain may be defined as a partial or complete rupture of a ligament, a strain as a partial tear of muscles and a bruise as a rupture of tissue leading to a haematoma. Any soft-tissue injury may lead to a haematoma, scarring and fibrosis and loss of function.

Background: Bone, soft-tissue, and nerve deficits of the weightbearing surface of the foot are frequent sequelae from foot trauma or diabetes mellitus and present challenging treatment issues. Injury to the specialized, shock-absorbing, heel-pad tissue containing spirally arranged fat chambers is particularly difficult to manage. Appropriate footwear modifications and shoe inserts for protection of this skin are essential to the long-term management of bone and soft-tissue defects of the heel. This study evaluated the performance of a new custom total contact foot orthosis (Hindfoot Containment Orthosis, HCO) which was designed to contain the soft tissues of the heel, reduce shear forces, redistribute weightbearing load, and accommodate bone or soft-tissue deformity of the heel. Methods: Twenty-two patients treated with HCO were retrospectively reviewed. Followup averaged 26 months. The effectiveness of the orthosis was assessed by how well the integrity of the soft tissue was maintained (e.g. the number of ulcerations since dispensing the orthosis), the number of refabrications of the orthosis that were required, and whether or not revision surgery was required. Results: Ten patients had superficial ulcerations. No patient required revision surgery. A total of 62 refabrications of the orthoses in 22 patients were required over a 2-year period. Overall results were good in 17 (77%) patients, fair in four (18%), and poor in one. Conclusions: The HCO is effective for preservation of soft-tissue integrity of the heel pad after bony or soft-tissue injury. Important factors in achieving success with the HCO are patient compliance and periodic monitoring for refabrication of the orthosis to accommodate skeletal growth, change in foot size or shape, and compression or wear of insert materials.

Abstract This proof-of-concept study demonstrates that repetitive loading to the pain threshold can safely recreate overloading-induced soft tissue damage and that localised tissue stiffening can be used as a marker for injury. This concept was demonstrated here for the soft tissue of the sole of the foot where it was found that repeated loading to the pain threshold led to long-lasting statistically significant stiffening in the areas where pressure was most intense. Loading at lower magnitudes did not have the same effect. This method can shed new light on the aetiology of overloading injury in the foot to improve the management of conditions such as diabetic foot ulceration and heel pain syndrome. At the same time, the presented concept can also enable the direct assessment of subject-specific thresholds for overloading in other soft tissues which are sensitive to pain, accessible for imaging and can be loaded in a clinically relevant manner.

Large majorities of dental traumas are associated with soft-tissue injury and tooth fragments. They are often found embedded in the oral soft tissues, most commonly the lip. Early detection and complete removal of such fragments is critical in order to prevent infection and scarring. Adequate communication between medical and dental professionals involved is of considerable value in the management of such cases. This report presents a case of spontaneous extrusion of an occult incisor fragment from the lower lip, eight months after trauma.

Participation in sports-related activities increases the risk for acute injury to soft tissues. In adults, the sites most often affected include the ankle, knee, and wrist joint structures, along with the muscles of the back and extremities. The subsequent inflammatory response to tissue damage results in pain and swelling, which limits mobility. A thorough patient assessment is required for accurate diagnosis and provides a guide for appropriate treatment. Initial management is based on the principles of basic first aid: rest, ice, compression, and elevation. Pharmacological therapy can also be used to achieve pain relief and improve mobility. There are few well-controlled studies addressing the pharmacotherapy of acute soft tissue injury, but clinical experience with nonsteroidal anti-inflammatory drugs is extensive. Both traditional and nontraditional therapeutic approaches are discussed.
