Soccer is one of the most popular sports with millions of active professional and non-professional players worldwide. Traumatic hip dislocations are rare in soccer but can lead to major sequelae both physically and psychologically. The aim of this review was to obtain insight into the outcomes after surgerically repaired hip fracture-dislocation in soccer players as well as rehabilitation and prevention. Two cases of a posterior hip fracture-dislocation that occurred during an amateur soccer match are presented and mechanism of injury, complications and rehabilitation were analysed. Follow-up of both patients was at least one year after surgery. Questionnaires and physical examinations were obtained to quantify and qualify outcome. In both cases the hip-dislocations were reduced within 3 h after injury. Semi-elective open reduction and internal fixation was performed within seven days. In one case, there was a concomitant Pipkin fracture and sciatic nerve neuropathy. There were no postoperative complications. Follow-up showed full of range of motion and normal hip functionality in both cases. However, both patients indicated a reduced quality of life and anxiety related to the accident. Traumatic hip fracture-dislocations during soccer practice are extremely rare. Despite uncomplicated fracture healing after surgery and return of hip function, both patients still suffer from psychological problems resulting in a decreased quality of life. Further research is required to enhance psychological outcomes, as well as to facilitate return to pre-injury levels of participation and engagement in sports following traumatic hip fracture-dislocations related to soccer.

Large posterolateral tibial fragments, known as Volkmann fractures, are common in ankle fracture-dislocations and typically require open reduction and fixation with interfragmentary screws and often buttress plates using a prone posterolateral approach. In this setting, fibula plating often necessitates dissection of the lateral window between the peroneal tendons and the skin, increasing wound-related complications. In recent years, intramedullary nailing of fibula fractures has gained popularity as a minimally invasive technique that allows load-sharing stabilization. However, this procedure has traditionally been performed in the supine position, which can pose challenges if a Volkmann-type fracture is present, requiring repositioning and losing access to the fibula through the posterolateral approach. Our objective is to describe a technique for fixing ankle fracture-dislocations with large posterolateral fragments using tibial buttress plates and fibula nails through a prone posterolateral approach without dissecting the lateral window. Additionally, we will present a case series with preliminary results. [ABSTRACT FROM AUTHOR]

C7-T1 translational injuries are relatively rare, unstable, and usually associated with neurological impairment. We aim to analyze the C7-T1 translational injury based on Allen and Ferguson's classification and to highlight the clinicoradiologic and neurologic outcomes in these patients. Patients with C7-T1 translational injury were retrospectively analyzed and demographic data, mechanism, mode of injury, surgery details, and associated injuries were obtained. The initial neurologic status was recorded as American Spinal Injury Association (ASIA) grade. All the injuries were classified as per Allen and Ferguson classification and stage 4 compressive extension (CE) injury was further classified into stage 4a and stage 4b according to Rebich et al. Among 44 patients, the most common mechanism of injury was CE injury seen in 27 patients (61.4%) followed by distractive flexion (DF) in 16 patients (36.4%) and compressive flexion in 1 patient (2.2%). Neurologic deficit was noted in 14 of 27 patients (51.85%) with CE injury, which was less compared to 12 of 16 patients (75%) with DF injury. However, there was no significant difference in terms of neurologic recovery. One patient with standalone anterior fixation had implant loosening and underwent additional posterior fixation. We present the largest series of C7-T1 translational injuries in the literature to our best knowledge. CE injury is nearly 2 times more common than DF injury and is associated with a lower incidence of neurologic deficit and easier fracture reduction techniques. Staging the injury severity aids in better planning in terms of surgical approach and levels of fixation. [ABSTRACT FROM AUTHOR]

To report the sequential treatment of a Type II odontoid fracture combined with a severe lower cervical (C6–7) fracture-dislocation featuring bilateral facet joint interlocking. A 58-year-old male who had suffered an injury in a car accident, He presented neck pain and extremity paralysis. His neurological function was classified as per the American Spinal Injury Association (ASIA) impairment scale as Grade A, indicating complete deficits below the C6 spinal cord level. A cervical CT scan and magnetic resonance image showed a type II odontoid fracture, C6 slipped anteriorly, C6–7 bilateral facet joint fracture and interlocking, slightly compression change of C7 upper endplate. Emergency closed reduction using cranial tong traction was success 6 h after the injury. A subsequent CT scan proved the successful reduction of bilateral facet joint dislocations and the odontoid fracture. After careful overall assessment, anterior cervical decompression and fusion (ACDF) was performed at C5–6 and C6–7 segments three days later，while odontoid fracture was treated conservatively. At the 4 months follow-up, a CT scan demonstrated solid bone fusion at C5–6, C6–7 segments, along with successful healing at the odontoid fracture site. However, spinal cord was necrosis at C5–7 segments, and the patient's neurological function had no improvement. The initial closed reduction could restore the alignment and preliminary stability of cervical spine at sub-axial cervical fracture-dislocation segment as well as displaced odontoid fracture. This timely and effective closed reduction significantly diminished sequential surgical trauma and mitigated associated risks. • Odontoid fracture concomitant with lower cervical fracture-dislocation was rare to report. • Initial closed reduction could restore anatomic alignment of both the upper and lower cervical spine; • Type II odontoid fracture could be treated conservative under the condition of complete reduction.

Introduction: Injuries involving the tarsometatarsal (TMT) joint are relatively uncommon, and the surgical treatment is potentially characterized by a high complications rate. The purpose of this study is to evaluate the results of the treatment of Lisfranc fracture-dislocations treated with closed reduction and percutaneous fixation with K-wires, considering complications and re-intervantion rate.Materials and Methods: A retrospective review was performed on all patients undergone closed reduction and percutaneous fixation with K-wires of a Lisfranc fracture-dislocation. Patients have been clinically evaluated at last follow up by American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score and Visual Analogue Scale (VAS), as well as by radiograph assessment.Results: Following inclusion and exclusion criteria, 15 patients have been included, with a mean age of 48.2 ± 5.6 years. Average follow-up was 3.8 ± 1.8 years (range 1-6). 7 fractures analyzed were classified as type A, 7 as type B (3 were B1, 4 were B2) and 1 as type C1. No case of loss of reduction has been observed at radiographic 1-month follow-up. At last follow-up mean AOFAS midfoot score and VAS score were respectively 82.2 ± 10.4 and 1.5 ± 1.3. Registered complications showed one deep vein thrombosis and 2 cases of complex regional pain syndrome (CRPS). One patient subsequently underwent arthrodesis of the tarsometatarsal joint for post-traumatic arthritis.Conclusions: The treatment of the fracture-dislocations of the Lisfranc joint by percutaneous reduction and fixation with K-wire can achieve good clinical outcomes with a low rate of complications and reoperations.Level Of Evidence: Level IV.

Tibial plateau fracture-dislocations are relatively uncommon injuries. They represent instability patterns due to injured collateral ligaments or extensive condylar depression. Medial and lateral subluxations of the fractured fragments represent the majority of these injuries. Posterior dislocations with the tibial plateau fractures are extremely rare injuries. Moreover, isolated posterior dislocations of the tibial condyles with a normally maintained position of the remaining tibia have not been reported in literature. We describe a difficult case scenario in which whole of the articular segment of the lateral condyle of the tibia was separated from its anterolateral rim and completely dislocated posteriorly, with no contact with the lateral condyle of the femur. Besides this, there was a complete disruption of the proximal tibiofibular joint as well. To further add to the problem, the distal pulses in the affected limb had a reduced volume. Stepwise management of all aspects of this injury has been described in this technical note along with a six-month follow-up. [ABSTRACT FROM AUTHOR]

The thoracic spine is stable because of kyphotic alignment, rib cage, and costovertebral joints. Any compression or kyphosis in the thoracic spine always causes spinal cord injury. A 47-year-old male with complaints of back pain 1 day prior to admission, after he sustained a motorbike crush and landed on his back. The pain, radiates to both limbs, associated with severe spasms, numbness, and weakness in his lower extremities, however no incontinence. No other associated injuries were reported. 25 years ago he had a history of tuberculosis of the spine with progressive deformity of the back, he was treated medically without surgery. On examinations: Gibbus at T11-L1, with hyper-pigmented post-inflammatory skin and an easily palpable spine, power 1/5 right and 2/5 left lower limbs, Sensation and bulbocarvenosus reflex were intact. Upper limbs were neurologically intact. All laboratory investigations including FBP, ESR, Electrolytes, renal and liver function tests were all within normal range. After radiological imaging, a final diagnosis of Spinal Cord Injury, ASIA C. AO classification type T12-L1:C/T9-L1:A4/N3/M2 was made. He was kept on a thoracolumbar corset 6 weeks after being initiated on spine protocol. He was discharged 8 weeks this time patient had no back pain but no improvement was noted neurologically. After a year of thoracolumbar corset and physiotherapy, he reported no more back pain, no numbness to lower limbs, and power 3/5 right and 4/5 left lower limbs, with intact sensation. However, no changes were observed radiologically. Due to the instability of fracture-dislocation, surgical treatment is recommended to realign the spine but for this case with back deformity and fractured vertebra bodies, it is best not to temper with reduction and fixation as it would further worsen the neurological deficit of the patient, during maneuvers while doing the reduction. Fracture-dislocation of the thoracic spine can impact the physical and mental well-being of the patients. Surgical fixation and instrumentation are ideal but in cases where surgical intervention would further impair the neurological function of the patient conservative management is the goal. • thoracic spinal fracture-dislocation is usually accompanied by complete neurological dysfunction and multiple costal fractures • 47years male patient with a complete anteroposterior dislocation of the thoracic vertebral following a trivial injury • 25years history of Ankylosing spondylitis secondary to Tb-spine • Treated conservatively with thoracolumbar corset [ABSTRACT FROM AUTHOR]

Introduction: Tarsometatarsal joint complex (TMC) is the anatomical structure of midfoot composed by metatarsals, tarsometatarsal (TMT) joints, cuneiforms, cuboid and navicular. TMC lesion are rare but critical since they cause severe disability if misdiagnosed. The knowledge of anatomic pattern of the lesion and biomechanics of the midfoot is the key for a successful diagnosis and treatment. The aim of this study was to review a consecutive series of TMC injuries analyzing preoperative radiograph and CT scan to accurately define the pattern of ligament and bone injuries.Material and Methods: We reviewed a series of 24 complete TMC injuries with homolateral dorsolateral dislocation. The total TMT joints involved were 120. We observed if the lesions were pure ligamentous or fracture-dislocation detecting the extent and the location of fractures. Twenty-nine lesions (24%) were pure dislocations and they were mainly localized in the first and fifth ray. The fracture-dislocations were 91 (76%) and 25 were fractures of the proximal row (cuneiforms and cuboid), 39 of the distal row (metatarsals), 27 of both the distal and proximal row.Results: Proximal fracture had a homogeneous distribution and they were more frequently simple than comminuted. Comminuted fractures were more frequent in the cuboid. In the proximal row, majority of partial articular fractures were localized in the dorsal side. Fracture-dislocations of the distal row were more frequent in the second metatarsal base (100%) and the partial articular fractures were always placed in the plantar side. In TMC injuries fracture-dislocations are more frequent than pure dislocations. Pure dislocations occur more often in the marginal rays that are characterized by weaker ligaments and larger mobility. The second ray, where there is the more stable joint of TMC, was never dislocated with a pure ligamentous lesion.Conclusions: We suppose that plantar avulsion from the distal row and dorsal compression fracture of the proximal row is consistent with a direct force applied to the forefoot and direct dorsolaterally. The direction of the forces may explain why some fractures occur in the distal row, some in the proximal and some in both rows. The thickness of plantar ligaments may explain the frequency of plantar bone fragment avulsion. [ABSTRACT FROM AUTHOR]

Irreducible ankle fractures are a relatively rare phenomenon. We present a case of a pronation abduction-type ankle fracture that was irreducible in the emergency room despite sedation. The patient was taken to the operating room, where the posterior tibialis tendon and retinaculum, deltoid ligament, and anteromedial capsule were found to be trapped within the joint. After removal of the tissue, alignment was restored. The patient did well clinically and was advanced to full weightbearing at 6 weeks. This is, to the best of our knowledge, the first report of entrapment of all 4 anatomic structures, preventing closed reduction. [ABSTRACT FROM AUTHOR]

Transolecranon fracture-dislocations are a rare type of olecranon fracture-dislocation of the elbow involving an olecranon fracture with an anterior radiocapitellar dislocation. In these fractures, the relationship between the proximal radioulnar joint is maintained. Principles of surgical fixation involve anatomical articular reduction of the olecranon, reduction of the radiocapitellar joint, and restoring elbow stability to allow early range of motion. With proper recognition of this fracture pattern and application of fixation principles, good outcomes can be expected for the majority of patients after this high-energy injury.

Introduction The main goal of the treatment is the anatomical reduction of the ulna fracture and the radial head dislocation in acute and chronic Monteggia cases. Acute pediatric Monteggia lesions are generally treated non-surgically; however, the treatment of chronic Monteggia is challenging. The aim of this article is to share our experiences about treatment of neglected Monteggia lesion. Presentation of case A 6-year-old girl who underwent a surgery in our clinic for a missed Bado type-III Monteggia fracture-dislocation of the right elbow with concomitant posterior interosseous nerve (PIN) palsy, which resolved spontaneously after the operation. The operation consisted of open reduction of the radial head, transverse ulnar osteotomy and fixation with an intramedullary Kirchner wire, and annular ligament repair without exploring PIN. The patient was seen in routine follow-up periods until the postoperative first year using plain radiographies. At 16th week follow-up, all functions of the PIN were returned. At first-year follow-up, full range of elbow motion was observed; plain radiographies showed radiocapitellar joint congruency, and Mayo Elbow Performance Index was one hundred. Discussion Treatment planning for chronic, neglected or missed Monteggia fractures is challenging. There is no consensus about the definitive treatment in the literature. Conclusion We recommend anatomic and stable restoration of radiocapitellar joint by correcting ulna deformity. Radiocapitellar fixation and PIN exploration may not be necessary in all neglected Monteggia lesions. [ABSTRACT FROM AUTHOR]

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 context: Traumatic fractures of the spine are most common at the thoracolumbar junction and can be a source of great disability. Purpose: To review the most current information regarding the pathophysiology, injury pattern, treatment options, and outcomes. Study design: Literature review. Methods: Relevant articles, textbook chapters, and abstracts covering thoracolumbar spine fractures with and without neurologic deficit from 1960 to the present were reviewed. Results: The thoracolumbar spine represents a unique system from a skeletal as well as neurological standpoint. The rigid rib-bearing thoracic spine articulates with the more mobile lumbar spine at the thoracolumbar junction (T10 - L2), the site of most fractures. A complete examination includes a careful neurologic examination of both motor and sensory systems. CT scans best describe bony detail while MRI is most efficient at describing soft tissues and neurological structures. The most recent classification system is that of the new Thoracolumbar Injury Classification and Severity Score. The different fracture types include compression fractures, burst fractures - both stable and unstable -, flexion-distraction injuries and fracture dislocations. Their treatment, both operative and non-operative depends on the degree of bony compromise, neurological involvement, and the integrity of the posterior ligamentous complex. Minimally invasive approaches to the care of thoracolumbar injuries have become more popular, thus, the evidence regarding their efficacy is presented. Finally, the treatment of osteoporotic fractures of the thoracolumbar spine is reviewed, including vertebroplasty and kyphoplasty, their risks and controversies, and senile burst fractures, as well. Conclusions: Thoracolumbar spine fractures remain a significant source of potential morbidity. Advances in treatment have minimized the invasiveness of our surgery and in certain stable situations, eliminated it all together. [Copyright &y& Elsevier]

Background: Complex fracture-dislocations of the proximal ulna and radius represent a challenge even for expert orthopaedic surgeons. A new comprehensive classification, the proximal ulnar and radial fracture-dislocation comprehensive classification system (PURCCS), was recently proposed. The aim of this study was to analyze the clinical usefulness of this classification in a large series of patients. Materials and methods: We studied 38 patients (39 elbows) with a mean age of 56 years. All patients were classified with the PURCCS by use of standard radiography, computed tomography, and intraoperative fluoroscopy. Surgical treatment was performed according to the PURCCS therapeutic algorithm. Patients were followed up for a mean of 23 months. The clinical evaluation was performed with the Mayo Elbow Performance Score and Index (MEPS and MEPI); the Disabilities of the Arm, Shoulder, and Hand (DASH) score; and the modified American Shoulder and Elbow Surgeons (m-ASES) score. Results: Each pattern of fracture-dislocation in our series finds its position within the PURCCS. At the last follow-up, the mean MEPS, DASH score, and m-ASES score were 91.2, 14.9, and 83.9, respectively. The mean extension, flexion, pronation, and supination were 19°, 136°, 81°, and 79°, respectively. According to the MEPI, 72%, 20%, and 8% of cases were rated excellent, good, and fair, respectively. Two patients with elbow stiffness underwent a reoperation, with final satisfactory results. Conclusion: The PURCCS helps identify the main lesions of each injury pattern; the associated therapeutic algorithm helps select correct surgical strategies. This study showed that the clinical results were satisfactory in the majority of cases, with few major complications and reinterventions. The PURCCS is a comprehensive classification that may contribute to the surgical management of these difficult fracture-dislocations. [Copyright &y& Elsevier]

Résumé: La fracture–luxation palmaire de l’articulation interphalangienne proximale (IPP) des doigts est une lésion rare. Nous rapportons une forme complexe chez un adolescent de 16ans, associant une fracture–luxation palmaire à une fracture de la base de la phalange intermédiaire, déplacée avec le fragment dorsal luxé en avant, entre la plaque palmaire et le col de la phalange proximale. Le traitement a été chirurgical avec réduction à ciel ouvert et fixation des différents fragments par brochage et arthrorise temporaire de l’articulation. Le résultat à six mois après ablation de la broche d’arthrorise et mise en route d’un protocole de kinésithérapie a été satisfaisant. Le patient était indolore avec un arc de mobilité de 115°. Cliniquement, la stabilité sagittale et frontale de l’IPP concernée en flexion et en extension était maintenue. Les radiographies de contrôle ont confirmé la consolidation du foyer fracturaire ostéochondral et de l’insertion osseuse de la bandelette médiane. Le patient a repris ses activités habituelles. Ce cas clinique est l’occasion d’une mise au point sur les fractures–luxations palmaires de l’IPP à travers leur fréquence, leur mécanisme de survenue et leur traitement. [ABSTRACT FROM AUTHOR]

Abstract: Complete dislocation of the tarsal navicular, without fracture of the navicular, is an uncommon injury. A review of the published data revealed only 15 previous reported cases. The rarity of this injury can be attributed to the rigid bony and ligamentous support surrounding the navicular, which usually undergoes fracture and dislocation rather than pure dislocation of the navicular. The mechanism and appropriate treatment of this injury remains unclear. In the present report, we describe the case of a 29-year-old male who sustained complete dislocation of the tarsal navicular, without fracture of the navicular, along with fractures of the cuboid and calcaneus, when he was involved in a motor vehicle collision. The proposed mechanism of injury in this case was that of a pronation-abduction force applied to the midfoot, resulting in a transient midtarsal dislocation and disruption of the ligamentous support of the navicular, with medial dislocation of the navicular when the midtarsal dislocation was reduced. The anterolateral calcaneus and cuboid fractures were likely from an avulsion injury through the bifurcate ligament. The patient was treated successfully with closed reduction and Kirschner wire fixation of the navicular combined with application of a spanning external fixator. The pins and external fixator were removed at 7 weeks postoperatively, and the navicular was stable at that time. The patient was lost to follow-up shortly thereafter. [Copyright &y& Elsevier]

Abstract: Bilateral anterior dislocation of the shoulders with fractures of both greater tuberosities is very rare. A 76-year-old woman sustained a bilateral anterior dislocation of her shoulders with fractures of the greater tuberosity on both sides after a fall on stairs. Her arms were abducted and externally rotated. Radiological examination revealed the bilateral anterior dislocation and also the bilateral fractures of the greater tuberosity. Prompt closed reduction followed by a 3 weeks immobilization and subsequent rehabilitation allows a good outcome. Results at one-year follow-up were satisfactory with normal range of motion and no redislocations occurring. To our knowledge, this is the first reported case of bilateral anterior shoulder dislocation associated with fractures of both greater tuberosities in elderly woman. [Copyright &y& Elsevier]

Background: Complex fracture-dislocations of the proximal ulna and radius include multiple anatomic lesions, the management of which is known to be demanding. Although several classifications have been proposed, none appear to be exhaustive, and most of them have neither therapeutic nor prognostic value. The purpose of this study was to design a comprehensive classification that may provide a guide for the operative management of these injuries. Materials and methods: The classification is aimed at identifying definite anatomic lesions, called the “main lesions,” the presence of which can affect the prognosis and require peculiar treatments. The main lesions include (1) ulnar fracture (including its location with respect to the insertion of collateral ligaments and coronoid fracture), (2) radiohumeral dislocation, (3) proximal radioulnar dislocation, (4) radial fracture, (5) distal radioulnar joint and interosseous membrane lesion, and (6) humeral-ulnar dislocation. Intraobserver and interobserver reliability was assessed in 25 complex fracture-dislocations. Standard radiographs and computed tomography scans were analyzed by 3 independent observers. Results: The main lesions were labeled by an alphanumeric system. Numbers 1 through 6 identified the type of ulnar fracture, and letters A through E indicated the dislocated joint or presence of a radial fracture. The direction of dislocation and the type of radial fracture were identified by Roman numerals, from I to III, placed after the letter. A κ value of 0.873 or greater resulted from intraobserver and interobserver evaluation. Conclusion: We created a comprehensive classification of complex fracture-dislocations of the elbow. The classification appeared to be reproducible and may represent a useful tool for the management of such difficult injuries. [ABSTRACT FROM AUTHOR]

Abstract: Background: Glenohumeral dislocations occurring during snowboarding and skiing are severe and often leave after effects. However, little is known about their aetiology and injury pattern. The purpose of this study was to elucidate the feature of glenohumeral dislocations in these winter sports. Methods: The injuries sustained by snowboarders and skiers, who were admitted to our hospital during five ski seasons from 2004 to 2009, were analysed using questionnaires and patients’ records. A retrospective cohort study and a multivariate regression analysis were performed to reveal the epidemiology and injury pattern of glenohumeral dislocations. Results: The overall rate of glenohumeral dislocation was 0.0583 per 1000 participant days (0.0676 per 1000 participant days in snowboarders and 0.0295 per 1000 participant days in skiers). Glenohumeral dislocations in snowboarding were significantly more common in higher age, male gender, injuries resulting more from falls, wet snow conditions, injuries of the leading-side joint and engaging the toe-side edge of the snowboard. Similarly, in skiers, glenohumeral dislocations were significantly more common in higher age, male gender, higher skill level, injuries resulting more from falls and injuries occurring on steep slopes. Nearly all (95.8%) of the glenohumeral dislocations were of the anterior type, and the prevalence of fracture-dislocations of the glenohumeral joint was higher in skiing (33.9%) than in snowboarding (12.4%). The variables strongly associated with glenohumeral dislocations in snowboarding and skiing were age, gender, snow condition and skiing speed. Conclusion: Snowboarding and skiing are sports with increased risk of glenohumeral dislocation compared with the general population, and the injury pattern differs between them. In snowboarding, injury patterns seem to be influenced by performance style. [Copyright &y& Elsevier]

Abstract: Background/Purpose: Acetabular fractures are a relatively uncommon fracture type. Among patients with acetabular fractures, posterior wall fractures are the most common. Open reduction and internal fixation is the treatment of choice for this type of injury. Anatomical reduction with rigid fixation as early as possible is the immediate goal of surgical treatment. This study retrospectively evaluated the clinical outcomes and radiographic findings of our clinical practices. Materials and methods: This study analyzed the short-term clinical results of 16 cases of acetabular posterior fracture-dislocations with 2 to 6 years of postoperative follow-up. The first study group included 13 patients who underwent open reduction and internal fixation with plates and screws. The second study group included 3 patients who underwent open reduction and internal fixation with screws only. Results: The second group who underwent fixation with small AO screws alone failed to provide enough rigidity and led to premature failure in three cases. Otherwise, there was only one case of implant failure in fixation with plates and screws, because of nonunion of the fracture site 8 months after surgery. Conclusions: We recommend using buttress plates with screws for the fixation of the fractures in this relatively uncommon injury, especially in younger patients. Total hip arthroplasty, using femoral head autografting to augment acetabular deficiency, is a reliable salvage procedure for failed open reduction and internal fixation of acetabular posterior fracture-dislocations.

Purpose: A percutaneous, intramedullary fracture reduction technique for treatment of unstable dorsal fracture-dislocation of the proximal interphalangeal (PIP) joint is described and the clinical and radiological results are reported. Methods: We conducted a retrospective clinical follow-up of 16 patients with 18 dorsal fracture–dislocations of the PIP joint. After closed joint reduction, we used an extension block K-wire to maintain the joint reduction. Impacted volar articular fragments were reduced percutaneously under fluoroscopy control using a pre-bent K-wire inserted through the intramedullary canal of the middle phalanx. The patients initiated passive range of motion exercises immediately after surgery. After a mean of 3 weeks, we removed the extension block K-wire and allowed free mobilization. We examined 13 patients with 15 injured fingers at a mean 5-year follow-up (range, 1–8 y). Results: Radiographic reduction of the joint dislocation was achieved and maintained. The mean articular step-off decreased from 2.1 mm (range, 1.6–3.1 mm) to 0.5 mm (range, 0.0–1.2 mm). At the final follow-up, active PIP motion averaged 83° (range, 65° to 97°) with a mean flexion contracture of 3° (range, 0° to 15°). The mean visual analog scale score for digit pain was 1/10. The mean Disabilities of the Shoulder, Arm, and Hand score of 4/100 indicated little functional impairment. Conclusions: Percutaneous, intramedullary reduction of the impacted volar articular fragments associated with unstable, dorsal fracture–dislocation of the PIP joint restores joint congruence and function. Type of study/level of evidence: Therapeutic IV. [ABSTRACT FROM AUTHOR]

Abstract: Proximal row carpectomy (PRC) is a well-accepted procedure for the treatment of early post-traumatic degenerative disease of the wrist. Much less frequently, PRC has been advocated as an emergency procedure for irreparable fracture-dislocation of the wrist. Our objective was to compare the results of PRC in patients having undergone this procedure in the two contexts. We conducted a retrospective analysis of the clinical and radiographic results of six patients treated by emergency PRC as compared to six patients who underwent elective PRC. The mean follow-up was 36 months. Both the patient''s satisfaction and the grasp of the wrist joint were significantly better in patients who underwent PRC emergency as compared to those having undergone elective PRC. Quick DASH score, radiographic results, and return to work were also more favourable in these patients, but the difference between the two groups was not significant. This study confirms that PRC is a valuable salvage technique indicated in early posttraumatic wrist collapse. Moreover, when performed in emergency, the procedure shows even better subjective and objective results, allowing a majority of patients to return to their previous job. [Copyright &y& Elsevier]

Abstract: We present the case of a patient with a fracture-dislocation of the fifth metacarpal and a dislocation of the metacarpophalangeal joint (floating fifth metacarpal) combined with a fracture of the fourth metacarpal. The mechanism of injury and management of this uncommon injury is reported. The “floating fifth metacarpal” and the fourth metacarpal fracture were reduced by closed techniques with percutaneous fixation. Twelve months later, the patient had a full range of wrist and finger movement, he was pain-free and without any residual disability. [Copyright &y& Elsevier]

Abstract: We treated 15 patients with chronic unreduced hip fracture-dislocations at our hospital; all patients sustained the fracture-dislocations in motor vehicle accidents. All presented to our institution more than 6 months after initial treatment at their local hospitals with uncontained femoral heads; all underwent 1-stage total hip arthroplasty with bone grafting. These patients were monitored for a mean of 71.5 months (range, 36-96 months). All patients had significantly decreased pain, increased function, and increased range-of-motion scores using the Merle d''Aubigné scoring system. All grafts showed radiographic evidence of union. There were 2 dislocations, 1 transient peroneal nerve palsy, and 1 superficial infection. Total hip arthroplasty is effective for relieving pain and restoring function in chronic unreduced hip fracture-dislocations. [Copyright &y& Elsevier]

Purpose: Unstable fracture-dislocations of the proximal interphalangeal (PIP) joint remain a difficult management problem, often leading to residual pain, stiffness, and recurrent instability. In a military setting, an easily applied, simple to operate, and inexpensive device becomes an attractive option. The purpose of this clinical investigation was to retrospectively review use of dynamic distraction external fixation (DDEF) for unstable fracture-dislocations and pilon injuries of the PIP joint in an active-duty population. Methods: The fixator is assembled under a local anesthetic from three 1.4-mm (0.045-inch) K-wires and rubber bands. It uses the principles of a lever and ligamentotaxis to assist and maintain reduction. Thirty-four members of the Armed Services, 27 men and 7 women (average age, 30 y), had DDEF for pilon fractures and unstable fracture-dislocations of the PIP joint. A retrospective review of these individuals was conducted. Final range of motion was determined from the clinical records at the final visit. Results: There were 26 PIP fracture-dislocations (3 chronic, average 6 weeks) and 8 PIP pilon injuries. The average follow-up period was 16 months (range, 6–84 months). The final arc of motion at the PIP joint averaged 88°, and the average distal interphalangeal joint arc of motion was 60°. Eight patients experienced superficial pin-track infections that were easily controlled with oral antibiotics. There were no cases of septic arthritis or osteomyelitis requiring intravenous antibiotics or premature fixator removal. Loss of reduction did not occur. All patients returned to their prior level of activity and duties. Conclusions: Our results are comparable with other techniques used in the management of unstable PIP joint fracture-dislocations. Easily applied and simple to operate, DDEF is a valuable addition to the hand surgeon’s armamentarium. We recommend its use for both primary and adjunctive treatment of acute and chronic unstable PIP joint fracture-dislocations and for primary treatment of PIP pilon injuries. Type of study/level of evidence: Therapeutic IV. [Copyright &y& Elsevier]

Summary: The radial head is involved in both elbow flexion and extension as well as forearm rotation and is an important stabiliser of the elbow. Fractures account for one-third of elbow fractures in adults and can lead to marked disability. Radial head fractures can be part of a spectrum of injuries to the elbow leading to complex instability. Management of comminuted fractures is controversial, but the present trend is towards stabilisation to allow early mobilization. The majority of radial head fractures are undisplaced and do not require operative treatment. Associated injuries to the elbow potentially leading to instability should be sought. In comminuted fractures with an intact MCL where fixation is not possible excision gives satisfactory long-term results. If instability is present radial length should be restored either by ORIF or replacement and any associated bony or ligamentous injuries repaired to allow early mobilisation to prevent stiffness.

Summary: Elbow fracture-dislocations are considered as difficult injuries to treat. Anterior olecranon fracture-dislocation consist an uncommon pattern which is likely to be under-diagnosed. Eight patients identified as anterior fracture-dislocation of the elbow were retrospectively reviewed. There were seven men and one woman with an average age of 35 years (range, 22–58 years). Proximal ulna fracture was comminuted in seven and simple oblique in one patient. Associated fractures were of coronoid in four and radial head in two. Reconstruction plate was used in seven patients and tension band wiring in just one. Nevertheless, tension wiring failed and was successfully revised to plate fixation combined with bone graft. Patients were followed for an average of 37.4 months (range, 10–50 months). The end results were two excellent, five good and one fair, based on Broberg and Morrey scale. An average score of 89 points was obtained using American Shoulder and Elbow Surgeons elbow scoring system. Treatment of anterior olecranon fracture dislocation is mostly satisfactory if contour and dimension of greater sigmoid notch is accurately restored. [Copyright &y& Elsevier]

Background Context: Due to the underlying pathology and altered biomechanics, traumatic cervical fractures have been reported in patients with ankylosing spondylitis (AS), diffuse idiopathic skeletal hyperostosis (DISH), ossification of the posterior longitudinal ligament (OPLL), and combination of DISH and OPLL. However, incidence of a fracture-dislocation through a solid multilevel anterior cervical discectomy and fusion (ACDF) construct with no associated underlying pathology of AS, DISH, or OPLL but severe osteopenia has not, to the best knowledge of the authors, been reported in the medical literature. Purpose: To report the development of an unstable cervical spine fracture that occurred through a previous multilevel anterior cervical fusion and the challenges associated with the diagnosis and surgical management of these uncommon lesions. Study Design/setting: A case report and review of the literature. Methods: A case report entailing the clinical history, operative management, and postoperative course of a 72-year-old male patient with no known AS, DISH, or OPLL who suffered a cervical spine fracture-dislocation, secondary to a motor vehicle accident, through a previous solid three-level ACDF that was performed 20 years earlier. Results: The patient underwent emergent reduction and realignment of the cervical fracture-dislocation, eventual posterior spinal fusion and stabilization with rigid segmental internal fixation, and application of external halo immobilization. At recent follow-up, he has radiographic evidence of fusion and maintenance of sagittal alignment without loss of reduction. Conclusions: Multilevel cervical fusion constructs are susceptible to traumatic injuries. Many of the same challenges in the management of the previously fused ACDF patient, who sustains a fracture-dislocation, are similar to those found in the patient with mass-inflammatory conditions or metabolic disorders, such as AS, DISH, or OPLL. In many cases, this includes severe osteopenia, long unstable fusion segments, and difficulties associated with prolonged halo vest immobilization. As a result, preoperative surgical planning should take into consideration the difficulties in achieving fracture reduction, decompression, and proper stabilization. [ABSTRACT FROM AUTHOR]

The aim of this study was to evaluate 1) long-term results of ankle fractures with a posterior malleolar fragment, and 2) the need for fixation of fragments smaller than 25%. Forty-five patients with ankle fractures and a posterior malleolar fragment were evaluated. Mean follow-up was 13 years (range, 2–24). The size and fixation of the fragment were registered. Outcome was assessed using an Ankle Fracture Scoring System (maximum: 150 points), a 10-point Numeric Scale for Pain (1 = no pain, 10 = unbearable pain) and an OsteoArthritis Score (0 = no osteoarthritis, 3 = severe osteoarthritis). The mean Ankle Fracture Scoring System, Numeric Scale for Pain and Osteoarthritis-score were 124, 2.5, and 1.2, respectively. The mean size of fixated fragments was significantly larger than that of nonfixated fragments (30% versus 16%). Those patients in which the posterior malleolar fragment was fixated did not have a statistically significant better outcome than those patients in which the fragments were not fixated (Ankle Fracture Scoring System: 119 versus 126, Numeric Scale for Pain: 2.6 versus 2.4, Osteoarthritis-score: 1.0 versus 1.2). There was no significant correlation between outcome and size of unfixated fragments. Fracture-dislocation was seen more often in combination with larger fragments (24% versus 15%) and resulted in statistically significant worse long-term outcome than nondislocated fractures, except for pain (Ankle Fracture Scoring System: 115 versus 134, Osteoarthritis-score: 1.7 versus 0.8). In conclusion, patients showed good results after 13 years follow-up and there was no evidence for the need for fixation of fragments smaller than 25%. [Copyright &y& Elsevier]

Summary: Lisfranc injuries are relatively uncommon injuries but with increasing motor vehicle use their incidence may be increasing. Missed injuries can lead to chronic pain, deformity and disability and this can be avoided by having a high index of suspicion. Subtle injuries are difficult to diagnose and special imaging or stress X-rays are useful in diagnosis. The classification proposed by Hardcastle et al. (J Bone Joint Surg 64-B (1982) 349) is used most commonly and the aim of treatment must be to obtain an anatomical reduction and stable fixation as soon as possible. Treatment after 6 weeks yields poor results and salvage arthrodesis is inferior to primary reduction and stabilisation. Reduction may be by closed or open methods and fixation by K wires, screws or bioabsorbable screws. Complications occur frequently and need to be detected and managed appropriately.

Abstract: Lisfranc fracture-dislocation is rare. The authors report a retrospective series of 17 cases managed by a single surgeon between 1990 and 1998. The series comprised 12 male (71%) and five female patients, aged between 11 and 62 years (mean age=33.4 years). Etiology was predominantly road accidents (64%). On Lerat classification, 12 lesions were homolateral and five divergent. Seventy eight percent of the patients had other associated lesions and 53% were polytraumatised. Fourteen patients were treated by pinning: percutaneous in six cases and open in eight; the other three patients were seen at a late stage and underwent Lisfranc joint realignment arthrodesis. One patient died from severe cranial trauma; 12 were followed up for between 1 and 7 years (mean follow-up=4.5 years). The eight patients managed by open or closed K-wire fixation and who were followed up had a mean midfoot Kitaoka score of 78/100: five results were good or excellent, two fair and one poor. Only 40% of the X-ray checks were strictly normal, the others disclosing joint alterations. The three cases managed by realignment arthrodesis showed union at 4 months'' follow-up, with a mean Kitaoka score of 88.3/100 (2 excellent and one fair result). [Copyright &y& Elsevier]

Transstyloid radiocarpal dislocation is a rare injury. It is due to high-energy trauma. It usually associates a radiocarpal dislocation, a fracture of the radial and/or cubital styloid process, and a cortical volar/dorsal margin avulsion. We present a case of a 31-year-old male who sustained a fell from a 4 m height causing a transstyloid radiocarpal dislocation. He was treated with a radial styloid process pinning and wrist arthrorisis with and splint immobilization. Different treatment options can be available for this type of injury with or without ligaments reconstruction. Although it is rare, the transstyloid radiocarpal dislocation has a good outcome with different types of treatment. • Transstyloid radiocarpal dislocation is rare. • Different surgical options are available. • Arthrorisis pinning is a good treatment option. • Functional outcome is usually good.

We present a case of a man who sustained a closed dorsal fracture–dislocation of his left ring finger proximal interphalangeal joint in a fall. The patient was treated surgically with plate and screw fixation via a volar approach. This method theoretically provides more secure fixation than internal fixation with screws alone, allowing early rehabilitation with active range of motion and potentially better functional outcome.

Axial fracture-dislocations are rare, high-energy injuries. Although cases of axial fracture-dislocations are reported in the literature, there are few reports of a patient who suffered a combined perilunate injury with an ulnar axial dislocation of the hand. This case report describes the anatomical injury and operative treatment of a patient who suffered this injury and discusses the importance of associated soft tissue management.

Background Fracture-dislocation is the extreme variant of injury to the proximal humerus that occurs more commonly in young adults as a result of high-velocity trauma. We evaluated the functional and radiologic outcome of fixation of proximal humeral fracture-dislocations with locked plates. Methods This was a retrospective review of 33 proximal humeral fracture-dislocations in 29 patients with a mean age of 35 years (range, 19-60 years) treated by open reduction and internal fixation with locked plates between January 2009 and December 2013. The fracture-dislocation in 85% was the result of high-energy trauma resulting in 3- or 4-part fracture-dislocation. The fracture-dislocation was anterior in 27 and posterior in 6. Results The average delay from injury to surgery was 7 days (range, 1-35 days), with a mean follow-up of 40 months (range, 24-66 months). All of the fractures united at an average of 15 weeks after surgery. At the final follow-up, the mean forward flexion was 129° (range, 100°-160°), and mean abduction was 128° (range, 100°-150°). The mean Constant score at the final follow-up was 78 points (range, 68-88 points). One case of complete osteonecrosis of the humeral head and 1 case of partial osteonecrosis of the humeral head were noted. Two cases of screw perforation of the humeral head were seen, with subsequent restricted range of motion improving after removal of the offending screws. Conclusions Most young patients with 3- and 4-part proximal humeral fracture-dislocations can achieve good functional outcome after fixation with locked plates. [ABSTRACT FROM AUTHOR]
