A novel variant of type-II Monteggia equivalent in an adult: A case report with a 6-year follow-up.

Case: An 18-year-old right-handed male student presented after a road-traffic-accident; he had type-II Monteggia fracture dislocation associated with ipsilateral type-I capitellum fracture and comminuted lateral condyle avulsion fracture. He underwent open reduction and fixation of ulna with 3.5 DCP with autologous olecranon bone grafting and fixation of capitellum using Herbert screw along with lateral collateral ligament (LCL) repair using fiber wire. At 6-years follow-up good outcome was seen without functional restrictions despite 15 degrees of restriction in pronation. Conclusion: Monteggia type-II variant with type-I capitellum fracture and LCL avulsion is a unique combination that represents a novel variant of type-II Monteggia equivalent, which adds to the existing classification of Monteggia equivalents.

Revolutionizing PIP joint fracture treatment: A case of surgical precision and rapid recovery.

INTRODUCTION: Proximal interphalangeal joint (PIPj) fractures are a common yet challenging injury, particularly in athletes. This case study explores innovative surgical techniques combined with targeted rehabilitation to optimize recovery and functionality. CASE PRESENTATION: A 20-year-old male soccer goalkeeper sustained a severe Proximal Interphalangeal Joint fracture-dislocation of the third finger during a game. He was treated using the wide awake local anesthesia no tourniquet (WALANT) technique and a Medartis TriLock plate, originally designed for the proximal phalanx but adapted for use on the middle phalanx. CLINICAL DISCUSSION: Immediate postoperative mobilization was facilitated by the WALANT technique, enhancing pain management and functional recovery. The adaptation of the TriLock plate, typically not used in this context, proved crucial for stabilizing the complex fracture. Follow-up included regular physiotherapy, focusing on mobility exercises and strength training, which were instrumental in the patient's quick return to sport. CONCLUSIONS: This case underscores the effectiveness of combining innovative surgical adaptations with early rehabilitation in treating complex hand injuries. Such approaches can lead to successful outcomes, significantly improving recovery times and functional results in athletic populations. This strategy may set a precedent for future treatment protocols in sports-related hand injuries.

Neglected Dorsal Proximal Interphalangeal Joint Dislocation Treated by Volar Plate Arthroplasty: A Case Series.

Chronic unreduced dislocations of the proximal interphalangeal joint are uncommon, and management principles for these injuries have not been defined. The dislocation can be volar or dorsal and closed reduction is rarely successful owing to soft tissue contractures. Treatment options in literature reviews for such rare injuries included open reduction of pip joint with volar plate arthroplasty, extension block pinning, hemi hamate arthroplasty, pip joint arthrodesis, Suzuki dynamic frame fixation, open reduction and repair of capsule and collateral ligaments with suture anchors. Few cases of amputation following treatment were even reported in literature emphasizing the role of meticulous soft tissue handling in such neglected cases of hand. We report six cases of neglected (more than three months old) dorsal dislocation of the PIP joint of the hand, treated with volar plate arthroplasty and extension block pinning. A functional range of motion with a stable joint can be achieved in such injuries with volar plate arthroplasty, as long as the articular cartilage is relatively preserved and bone loss is <30%.

Coronoid fractures and complex elbow instability: current concepts.

Fractures of the coronoid process typically occur as part of more complex injury patterns, such as terrible triads, trans-olecranon fracture-dislocations, posteromedial rotatory injuries or Monteggia-like lesions. Each pattern is associated with a specific type of coronoid fracture with regard to shape and size and specific soft-tissue lesions. O' Driscoll classification incorporates those associations identifying three major types of fractures: tip, anteromedial facet, and basal fractures. The objective of this study is to review the most common types of complex elbow instability, identify the indications for coronoid fixation and guide the appropriate management. Tip fractures as those seen in terrible triads can conditionally left untreated provided that elbow stability has been restored after radial head fixation and ligaments repair. Anteromedial facet fractures benefit from a buttress plate, while large basilar fractures can be effectively secured with posteroanterior screws. Coronoid reconstruction with a graft should be considered in post-traumatic cases of chronic coronoid deficiency.

Nitinol Staple Use in Primary Arthrodesis of Lisfranc Fracture-Dislocations.

BACKGROUND: Primary arthrodesis of Lisfranc fracture-dislocations is a reliable treatment option, yet concerns remain about nonunion. Nitinol staple use has recently proliferated in midfoot arthrodesis. The purpose of this study is to examine the union rate of primary arthrodesis of acute Lisfranc fracture-dislocations treated with nitinol staples compared with traditional plate-and-screw fixation. The secondary objective is to assess the difference in operative times and reoperation rates. METHODS: Midfoot fracture-dislocations treated with primary arthrodesis by 7 foot and ankle orthopaedic surgeons were reviewed. Of 160 eligible patients, 121 patients (305 joints) met the required 4-month minimum radiographic follow-up. Radiographic outcomes were analyzed at the individual joint level. Each joint was classified as either staples alone (45 patients, 154 joints), staples plus plates and screws (hybrid) (45 patients, 40 joints), or plates and screws alone (31 patients, 111 joints). The primary outcome was arthrodesis union at each joint fused. RESULTS: Nonunion was more common (9.0%, 10/111) among joints fixed with plate and screws than with hybrid (2.5%, 1/40) or staples only (1.3%, 2/154) (P = .0085). Multivariable regression demonstrated that autograft use was independent associated with union (P = .0035) and plate-and-screw only fixation was an independent risk factor for nonunion (P = .0407). Median operating room and tourniquet times were shorter for hybrid (92 and 83 minutes) and staple only (67 and 63 minutes) constructs compared to plate-and-screw only fixation (105 and 95 minutes) (P ≤ .0001 and .0003). There was no difference in reoperation rates among patients with different fixation types. CONCLUSION: We found that use of nitinol compression staple and bone autograft in primary arthrodesis of Lisfranc and midfoot fracture-dislocations was associated with both improved union rates and shorter tourniquet and operative times compared to traditional plate-and-screw fixation techniques. LEVEL OF EVIDENCE: Level III, therapeutic.

Thumb Metacarpal Periosteal Sleeve Avulsion: A Case Report.

Periosteal sleeve fractures, or avulsions of cartilage and/or periosteum with or without an osseous fragment in skeletally immature individuals, are notoriously easy to miss and a high index of suspicion is necessary for accurate diagnosis and treatment. While periosteal sleeve avulsion fractures are classically reported in the patella, they have also been reported in the shoulder, clavicle, and elsewhere in the knee. However, no published reports exist for a periosteal sleeve avulsion fracture in the hand. This case details the first reported instance of such an injury involving a thumb metacarpal in a 3-year-old boy, treated with open reduction and percutaneous pinning of the thumb metacarpal.

Case report: A complete lower cervical fracture dislocation without permanent neurological impairment.

BACKGROUND: Complete fractures and dislocations of the lower cervical spine are usually associated with severe spinal cord injury. However, a very small number of patients do not have severe spinal cord injury symptoms, patients with normal muscle strength or only partial nerve root symptoms, known as "lucky fracture dislocation". The diagnosis and treatment of such patients is very difficult. Recently, we successfully treated one such patient. CASE PRESENTATION: A 73-year-old male patient had multiple neck and body aches after trauma, but there was sensory movement in his limbs. However, preoperative cervical radiographs showed no significant abnormalities, and computed tomography (CT) and magnetic resonance imaging (MRI) confirmed complete fracture and dislocation of C7. Before operation, the halo frame was fixed traction, but the reduction was not successful. Finally, the fracture reduction and internal fixation were successfully performed by surgery. The postoperative pain of the patient was significantly relieved, and the sensory movement of the limbs was the same as before. Two years after surgery, the patient's left little finger and ulnar forearm shallow sensation recovered, and the right flexion muscle strength basically returned to normal. CONCLUSION: This case suggests that when patients with trauma are encountered in the clinic, they should be carefully examined, and the presence of cervical fracture and dislocation should not be ignored because of the absence of neurological symptoms or mild symptoms. In addition, positioning during handling and surgery should be particularly avoided to increase the risk of paralysis.

An Examination of Complication Rates and Surgery Durations in Elective Hand Surgery During the COVID-19 Pandemic.

Background: The COVID-19 pandemic presented unique challenges to hand surgeons as hospitals worked to adapt to unprecedented demands on resources and personnel. The purpose of this study is to evaluate the impact of COVID-19 on outcomes in elective hand surgery using a large national database. Methods: This is a retrospective review of the American College of Surgeons National Surgery Quality Improvement Program (ACS-NSQIP) dataset for patients undergoing elective hand procedures in 2019 and 2020. Demographics, comorbidities, procedural factors, and outcomes were compared between cases occurring in 2019 and 2020. Multivariable regressions were performed to evaluate the association between operative year and 30-day outcomes. Results: A total of 8971 patients were included with a mean age of 52.2 ± 16.7 and 52.8 ± 16.4 years for the 2019 and 2020 cohorts, respectively. Compared to the 2019 cohort, the 2020 cohort demonstrated higher prevalence of obesity (43.3% vs 40.8%, P = 0.019), hypertension requiring medication (32.9% vs 35.0%; P = 0.046), and American Association of Anesthesiologists (ASA) class ≥ 3 (30.4% vs 27.0%; P < 0.001). There were no significant differences in outcomes including 30-day readmissions, reoperation, or complications between cohorts on unadjusted or multivariable analysis. Conclusions: Elective hand cases performed during the pandemic were associated with longer operating times and more frequently involved patients with greater comorbidities. Despite these differences, patients undergoing surgery during the pandemic demonstrated similar outcomes including complications, readmissions, and reoperations compared to those undergoing surgery the year prior, suggesting that even in the setting of a pandemic, performing elective surgery is safe without an increased risk to the patient.

FRACTURE-DISLOCATIONS OF THE ELBOW: CAN THEY INFLUENCE THE PATTERN FRACTURE OF RADIAL HEAD?

Introduction: Radial head fractures are consistently part of a terrible triad of the elbow and can occur in association with Monteggia fracture-dislocations, transolecranon fractures, and their variations. Understanding the degree of comminution of the radial head fracture and the location of fragments determines the course of action to be taken. Objectives: To correlate fracture-dislocations with the pattern of radial head fracture (number of fragments) and involvement in the proximal radioulnar region. Materials and Methods: A retrospective study (level II) of patients undergoing surgery for radial head fractures associated with fracture-dislocations. Patients had radiographs in anteroposterior and lateral views, as well as tomography. The number of radial head fracture fragments and the presence of fractures in the proximal radioulnar region were correlated with the type of fracture-dislocation and demographic variables. Conclusion: Elbow fracture-dislocation types could not predict the number of fragments and the location of radial head fractures. However, most injuries presented three or more fragments in the radial head, and many had involvement of the proximal radioulnar region, suggesting high-energy trauma. Level of Evidence II; Retrospective Study.

Introdução: As fraturas da cabeça do rádio estão sempre presentes em uma tríade terrível do cotovelo e podem ocorrer associadas a uma fratura-luxação de Monteggia, fratura transolecraniana e suas variações. Conhecer o grau de cominuição da fratura da cabeça do rádio e a localização dos fragmentos determinam a conduta a ser tomada. Objetivos: Correlacionar as fraturas-luxações com o padrão da fratura da cabeça do rádio (número de fragmentos) e o acometimento na região radioulnar proximal. Material e Métodos: Estudo retrospectivo (nível II) de pacientes submetidos a cirurgia devido fraturas de cabeça de rádio associadas às fraturas-luxações. Os pacientes possuíam radiografia nas incidências anteroposterior e perfil e tomografia. O número de fragmentos da fratura da cabeça do rádio e a presença de fratura na região radioulnar proximal foram correlacionadas com o tipo de fratura-luxação e as varáveis demográficas. Conclusão: Os tipos de fratura-luxação do cotovelo não foram capazes de predizer o número de fragmentos e a localização da fratura da cabeça do rádio. Entretanto, a maioria das lesões apresentaram três ou mais fragmentos na cabeça do rádio e muitos apresentaram acometimento da região da radioulnar proximal sugerindo traumas de alta energia.

Rare Case of Open Comminuted Scaphoid Fracture Dislocation: Treatment With Free Bone Graft and Locking Plate.

To the best of our knowledge, there are no reports in the literature of an open comminuted scaphoid fracture dislocation. We present such a rare case. The case report illustrates the case of a 58-year-old right-handed press operator who injured his left wrist when his hand got caught in a press machine. He received initial treatment at another hospital and was subsequently referred to our hospital. Eight days after the injury, surgery was performed under the brachial plexus block. Successful bone fusion was achieved through volar locking plate fixation, primary free bone grafting from the radius, and Kirschner wire fixation. Our case report may be a valuable resource for the treatment of similar injuries.

Surgical management and functional outcomes of perilunate dislocations and fracture dislocations through the dorsal approach.

BACKGROUND: Perilunate dislocations and perilunate fracture dislocations (PLD/PLFDs) are rare injuries of the wrist, with surgical management leading to acceptable functional results. PURPOSE: The purpose of this study was to assess the functional outcomes of the patients of our department who were treated with surgical management of PLDs/PLFDs through dorsal approach, as well as to report any complications on their follow-up. PATIENTS AND METHODS: In this retrospective study, 52 patients with PLD/PLFD, fulfilling the inclusion and exclusion criteria of the study, underwent surgical management of their injury. All patients were followed up at 6 weeks, 12 weeks, 6 months, 1 year postoperatively with radiographic imaging as well as functional scores measured with the modified mayo wrist score and the QuickDASH questionnaire. RESULTS: The mean postoperative modified Mayo score was 76.8 ± 8.8 and the mean QuickDASH score was 1.52 ± 2.18. Of the 52 cases, 20% had excellent results, 42% had good results, 29% had fair results and 9% had poor results as per the modified Mayo wrist score. No patient signed any symptoms of median nerve neuropathy. CONCLUSION: In conclusion, open reduction and internal fixation through dorsal approach is a reliable technique to manage perilunate injuries in spite of radiological evidence of wrist arthritis, as it also provides consistently good results in terms of functional outcomes. LEVEL OF EVIDENCE IV: Retrospective case series study.

Anterior shoulder dislocation with avulsion fracture of the greater tuberosity results in reliable good outcomes after closed reduction.

Background: Avulsion of the greater tuberosity (GT) due to traumatic anterior shoulder dislocation (ASD) is a commonly observed fracture pattern. After closed reduction of the dislocated humerus, the GT typically reduces itself into its anatomic position enabling the patient to undergo conservative treatment. The aim of this study was to retrospectively review a consecutive series of patients with conservatively treated GT avulsion fractures after closed reduction of an ASD and analyze radiographic outcome, shoulder function and glenohumeral stability and the conversion rate to surgical treatment. Methods: All patients who underwent closed reduction of a GT avulsion fracture after ASD with the primary intention of conservative treatment between 2017 and 2022 were included. Complications (i.e. conversion to surgical treatment), shoulder function assessed with the American Shoulder and Elbow Surgeons score and subjective shoulder value, instability assessed with the Western Ontario Shoulder Instability score, radiological impingement (greater tuberosity index = GTI and impingement index = II) and GT fracture pattern were assessed as outcome measurements. Results: A total of 29 patients (mean age 44 years, 27% female) with a mean follow-up of 32.6 (range, 8-96) months were enrolled. Seven patients (24%) underwent surgery due to secondary displacement (n = 4, 14%) or impingement symptoms (n = 3, 10%). All patients who underwent secondary surgery showed a multifragmentary fracture pattern of the GT. Shoulder stiffness (n = 7) and neuropraxia of the axillary nerve (n = 3) were observed temporarily and resolved during the follow-up period. The American Shoulder and Elbow Surgeons and subjective shoulder value of the conservatively treated patients at the last follow-up was 89.2 ± 19.1 respectively 86 ± 18.2%. No recurrent glenohumeral dislocation was documented. The mean Western Ontario Shoulder Instability score at last follow-up was 8(0-71). The mean GTI decreased from 1.2 ± 0.1 after ASD to 1.1 ± 0.1 at the last follow-up (P = .002). The mean II decreased from 0.6 ± 0.5 after ASD to 0.4 ± 0.3 at the last follow-up (P = .110). Conclusion: The GT avulsion fragment reduces typically into a close to anatomic position after closed reduction and the GTI even improves with further conservative treatment over time. Close radiological follow-up is necessary to rule out secondary displacement which occurs typically in a multifragmentary fracture pattern. Patients without the need for surgery showed good clinical outcomes without recurrence of glenohumeral instability.

Vertebral Artery Injury in Cervical Spine Fracture Dislocation: An Observational Study in a Tertiary Care Center.

BACKGROUND: The incidence of traumatic vertebral artery injury (VAI) associated with cervical spine trauma varies widely in published trauma series. The primary aim of this study was to determine the incidence of traumatic VAI in patients who suffered cervical spine injuries by means of routine magnetic resonance imaging, and the secondary objective was to identify any associations with injury mechanism, level of injury, and neurologic injury severity.  Materials and methods: A retrospective review was conducted on 96 patients who suffered cervical spine fracture dislocation with or without an associated spinal cord injury (SCI) in Indian Spinal Injuries Center (ISIC), New Delhi, India from January 2013 to April 2023. Cervical magnetic resonance imaging (MRI) was used to diagnose VAI. Patient's age, sex, cervical injury level, mechanism of injury, neurologic level of injury, association with foraminal fracture, facet dislocation, and clinical sequelae of vertebral artery injury were analyzed. RESULTS: In this study, of 96 patients who met the inclusion criteria, 18 patients (18.75%) had VAI on the MRI study. Thirteen (72.22%) of the eighteen patients had right-sided injuries, four (22.22%) had left-sided injuries, and one (5.55%) had bilateral injuries. There was an associated SCI in every VAI patient. VAI was significantly more common in patients who had ASIA A (61%, n = 11) and ASIA B (22%, n = 4) injuries, and no VAI was noted in neurologically intact patients (p<0.001). The incidence of VAI was higher in the flexion distraction type of injury (n = 12, 66%). The most commonly involved cervical spine injury level was C5-C6 (27%, n = 5), followed by 22% (n = 4) at C4-C5 and C6-C7 levels. About 27.8% (n = 5) of VAI was associated with foraminal fractures, and 72% (n = 13) of VAI was associated with facet dislocations, of which 44% (n = 8) were bifacetal and 28% (n = 5) were unifacetal dislocations. On clinical symptoms, only one (5.56%) patient had a headache, and 17 (94.4%) had no clinical features due to VAI. CONCLUSION: The incidence of traumatic vertebral artery disease is not very uncommon and requires careful and meticulous screening and management. Otherwise, complications like pseudoaneurysm, neurologic deficit, late-onset hemorrhage, infarction, and death can happen. Mostly, it is associated with high-velocity injuries and neurological injuries. MRI can be used as a good screening tool, which can be aided by a CT angiogram or digital subtraction angiography for confirmation. Proper pre-operative evaluation of vascular injury in cervical spine fracture dislocation is very important for patient counseling, patient management, and surgical planning.

Three-Part Fracture Dislocation and Four-Part Fracture Dislocation of the Proximal Humerus: How Different are the Glenoid Labrum and Capsular Injuries Between Them?

Background: Anterior fracture dislocation of the shoulder may have associated injury to the glenoid labrum and/or capsule. There is a need to look at the possible patterns of capsulo-labral injuries intra-operatively and correlate them with pre-operative radiographs and CT scans. It can enable surgeons to predict the patterns of soft-tissue injuries in a specific fracture type. Methods: Patients operated for ORIF of 3- and 4-part anterior fracture dislocation between January 2017 and December 2022 were included in the study. The following data were collected: demographic details, fracture morphology and classification on radiograph and CT scan, neurovascular injury, the subtype of anterior dislocation, and intra-operative identifiable injury to glenoid labrum and/or capsule. Results: A total of 24 cases (mean age 40 ± 10 years) of anterior fracture dislocation of the shoulder were included in the study and were grouped based on Neer's classification. 12 patients had 3-part anterior fracture dislocation (3-part Group) with a mean age of 34 ± 9 years, while 12 patients had 4-part anterior fracture dislocation (4-part Group) with a mean age of 46 ± 7 years (p = 0.001). 10 out of 12 patients in the 3-part Group had the subcoracoid position of the dislocated head, whereas the head was present in 9 out of 12 patients of the 4-part Group at the preglenoid position (p = 0.003). The head position was at a mean distance of 1.85 cm from the anterior glenoid rim in the 4-part Group, whereas the head was engaged at the anterior rim of the glenoid in the 3-part Group. The medial metaphyseal beak was present in 11 out of 12 patients in the 3-part Group, whereas it was absent in all the cases of the 4-part Group (p = 0.001). 92% of the included patients in our study had capsulo-labral injury. 11 out of 12 patients in the 3-part Group had labral injury compared to 10 out of 12 patients in the 4-part Group with severe capsular stripping (p = 0.001). Conclusion: The 3-part fracture dislocation with radiological findings such as the long medial metaphyseal beak and subcoracoid position of the dislocated head had a strong association with a glenoid labral injury, whereas the 4-part fracture dislocation type had a widely displaced preglenoid position of the dislocated head with an absent metaphyseal beak and had a strong association with a capsular type of soft-tissue injury. Level of Evidence: III.

The Safety of Volar to Dorsal Percutaneous Screw Fixation of Bennett Fracture-Dislocation - A Cadaveric Study.

Background: Bennett fractures are traditionally fixed with percutaneous K-wires from dorsal to volar, or with a volar to dorsal screw via a volar open approach. While volar to dorsal screw fixation is biomechanically advantageous, an open approach requires extensive soft tissue dissection, thus increasing morbidity. This study aims to investigate the practicality and safety of Bennett fracture fixation using a percutaneous, volar to dorsal screw, particularly with regard to the median nerve and its motor branch during wire and screw insertion. Methods: Fifteen fresh frozen forearm and hand specimens were obtained from the University of Auckland human cadaver laboratory. A guidewire is placed under image intensifier from volar to dorsal with the thumb held in traction, abduction and pronation. The wire is passed through the skin volarly under image intensifier, then the median nerve is dissected from the carpal tunnel and the motor branch of the median nerve (MBMN) is dissected from its origin to where it supplies the thenar musculature. The distance between the K-wire to the MBMN is measured. Results: In 14 of 15 specimens, the wire was superficial and radial to the carpal tunnel. The mean distance to the origin of the MBMN is 6.2 mm (95% CI 4.1-8.3) with the closest specimen 1 mm away. The mean closest distance the wire gets to any part of the MBMN is 3.7 mm (95% CI 1.6-5.8); in two specimens, the wire was through the MBMN. Conclusions: Wire placement, although done under image intensifier, is subject to significant variation in exiting location. While research has shown the thenar portal in arthroscopic thumb surgery is safe, our guidewire needs to exit further ulnar to capture the Bennett fracture fragment, placing the MBMN at risk. This cadaveric study has demonstrated the proposed technique is unsafe for use.

A Review on Volar Fracture-Dislocations of the Proximal Interphalangeal Joint.

Volar fracture-dislocations of the proximal interphalangeal joint are rare injuries caused by an axial force on a flexed digit resulting in an avulsion fracture of the dorsal lip of the middle phalanx with volar dislocation of the joint. This volar subtype is analogous to the more common dorsal subtype with a mirror image fracture on the dorsal lip of the middle phalanx. The main significance in this type of injury lies in the disruption of the extensor mechanism at the central slip. The goals of treatment, apart from restoring a congruent and stable joint, is to restore the extensor mechanism to prevent a boutonnière deformity. In this article, we summarise the current literature and discuss the principles for treatment of this uncommon injury. Level of Evidence: Level V (Therapeutic).

The mini-open procedure with a modified figure of eight for managing sacrococcygeal fracture-dislocation: A case report and literature review.

INTRODUCTION AND IMPORTANCE: A fracture associated with an anteriorly displaced fragment may induce soft tissue disintegration. However, this might be avoided by maintaining the stability of the sacrococcygeal bone. Fixation by using less invasive modalities is needed to improve the outcome. CASE PRESENTATION: A 37-year-old female came with tailbone pain, which lasted around one month. There was a history of falling in a sitting position a month before hospital admission. Tenderness was positive while palpating the perineal site. A radiography examination shows a fracture in the sacrococcygeal segment with anterior dislocation. The patient was diagnosed with a sacrococcygeal fracture and anterior dislocation. CLINICAL DISCUSSION: We performed a mini-open procedure using a modified figure-of-eight technique to reconnect the sacrococcygeal bone. Suturing was performed through the skin in the painful area, and then the bone at the injured site was reduced. As an outcome, there was an improvement in the Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), and EuroQol-5 Dimensions (EQ5D) scores. CONCLUSION: A mini-open procedure with a modified figure of eight is a simple and valuable method for correcting the sacrococcygeal components.

Temporary immobilization methods for closed low-energy ankle fracture-dislocations: comparative analysis of a retrospective cohort.

PURPOSE: Ankle fracture-dislocations (AFD) often necessitate staged management involving temporary external fixation (EF) due to mechanical instability or blistering. However, limited literature exists on the optimal temporary immobilization method for low-energy closed AFD. This study compared baseline patient and fracture characteristics, along with clinical and radiological outcomes between AFD initially immobilized with EF versus splinting. METHODS: A retrospective cohort study was conducted involving patients with AFD temporarily immobilized using EF or splinting, followed by definitive open reduction and internal fixation. Quality of reduction (QOR) was assessed for each patient post-initial immobilization and after the definitive surgery. RESULTS: The study encompassed 194 patients: 138 treated with a splint (71.1%) and 56 (28.9%) with EF. Secondary loss of reduction had occurred in three patients who were splinted (2.2%). The mean ages in the EF and splint groups were 63.2 and 56.1 years, respectively (p = 0.01). Posterior malleolus fracture (PMF) and blisters were more prevalent in EF patients (69.6% vs. 43.5% for PMF and 76.8% vs. 20.3% for blisters, respectively; p = 0.05 and p < 0.01). Postoperative complication rates were 8.9% for EF versus 10.9% for splinting (p = 0.69). Satisfactory final QOR was attained in 79.8% of patients treated with a splint versus 64.3% with EF (p = 0.02). CONCLUSION: Patients immobilized by EF presented with poorer baseline characteristics and had more unstable injuries. Nevertheless, postoperative complication rates were comparable. Thus, EF appears to be a valuable tool for standardizing outcomes in AFD patients with a less favorable prognosis.

Reported Outcome Measures in Complex Fracture Elbow Dislocations: A Systematic Review.

BACKGROUND: Complex elbow fracture dislocations, dislocation with fracture of one or several surrounding bony stabilizers, are difficult to manage and associated with poor outcomes. While many studies have explored treatment strategies but a lack of standardization of patient-reported outcome measures (PROMs) makes cross-study comparison difficult. In this systematic review, we aim to describe what injury patterns, measured outcomes, and associated complications are reported in the complex elbow fracture dislocation literature to provide outcome reporting recommendations that will facilitate improved future cross-study comparison. METHODS: A systematic review was performed per PRISMA guidelines. We queried PubMed/MEDLINE, Embase, Web of Science, and Cochrane databases to identify articles published between 2010 and 2022 reporting on adult patients who had a complex elbow fracture dislocation. Pathologic fractures were excluded. A bias assessment using the methodological index for non-randomized studies criteria was conducted. For each article, patient demographics, injury pattern, outcome measures, and complications were recorded. RESULTS: Ninety-one studies reporting on 3664 elbows (3654 patients) with an elbow fracture and dislocation (weighted mean age 44 years, follow-up of 30 months, 41% female) were evaluated. Of these, the injury pattern was described in 3378 elbows and included 2951 (87%) terrible triad injuries and 72 (2%) transolecranon fracture-dislocations. The three most commonly reported classification systems were: Mason classification for radial head fractures, Regan and Morrey coronoid classification for coronoid fractures, and O'Driscoll classification for coronoid fractures. Range of motion was reported in 87 (96%) studies with most reporting flexion (n=70), extension (n=62), pronation (n=68), or supination (n=67). Strength was reported in 11 (12%) studies. PROMs were reported in 83 (91%) studies with an average of 2.6 outcomes per study. There were 14 outcome scores including the Mayo Elbow Performance Score (MEPS) (n=69 [83%]), the Disabilities of Arm, Shoulder and Hand (DASH) score (n=28 [34%]), the visual analog scale for pain (VAS) (n=27 [33%]), QuickDASH score (n=13 [15.7%]), and Oxford Elbow score (n=5 [6.0%]). No significance was found between the number of PROMs used per article and the year of publication (P=.313), study type (P=.689), complex fracture pattern (P=.211), or number of elbows included (P=.152). CONCLUSION: There is great heterogeneity in reported PROMs in the complex elbow fracture dislocation literature. Although there is no gold standard PROM for assessing complex elbow fracture dislocations, we recommend the use of at least the MEPS and DASH outcomes measures as well as VAS pain rating scale in future studies to facilitate cross-study comparisons.

[Effectiveness of injured vertebra fixation with inclined-long pedicle screws combined with interbody fusion for thoracolumbar fracture dislocation with disc injury].

Objective: To investigate the effectiveness of injured vertebra fixation with inclined-long pedicle screws combined with interbody fusion for thoracolumbar fracture dislocation with disc injury. Methods: Between January 2017 and June 2022, 28 patients with thoracolumbar fracture dislocation with disc injury were underwent posterior depression, the injured vertebra fixation with inclined-long pedicle screws, and interbody fusion. There were 22 males and 6 females, with a mean age of 41.4 years (range, 22-58 years). The causes of injury included falling from height in 18 cases, traffic accident in 5 cases, and bruise in 5 cases. Fracture segment included 1 case of T 11, 7 cases of T 12, 9 cases of L 1, and 11 cases of L 2. According to the American Spinal Injury Association (ASIA) scale, the spinal injuries were graded as grade A in 4 cases, grade B in 2 cases, grade C in 11 cases, and grade D in 11 cases. Preoperative spinal canal encroachment ratio was 17.7%-75.3% (mean, 44.0%); the thoracolumbar injury classification and severity score (TLICS) ranged from 9 to 10 (mean, 9.9). Seventeen patients were associated with other injuries. The time from injury to operation ranged from 1 to 4 days (mean, 2.3 days). The perioperative indicators (operation time, intraoperative blood loss, and the occurrence of complications), clinical evaluation indicators [visual analogue scale (VAS) score and Oswestry Disability Index (ODI)], radiologic evaluation indicators [anterior vertebral height ratio (AVHR), kyphosis Cobb angle (KCA), intervertebral space height (ISH), vertebral wedge angle (VWA), displacement angle (DA), and percent fracture dislocation displacement (PFDD)], neurological function, and interbody fusion were recorded. Results: The operation time was 110-159 minutes (mean, 130.2 minutes). The intraoperative blood loss was 200-510 mL (mean, 354.3 mL). All incisions healed by first intention, and no surgical complications such as wound infection or hematoma occurred. All patients were followed up 12-15 months (mean, 12.7 months). The chest and lumbar pain significantly relieved, VAS scores and ODI after operation were significantly lower than those before operation, and further decreased with the extension of postoperative time, with significant differences ( P<0.05). At last follow-up, the ASIA classification of neurological function of the patients was grade A in 3 cases, grade B in 1 case, grade C in 1 case, grade D in 10 cases, and grade E in 13 cases, which was significantly different from preoperative one ( Z=-4.772, P<0.001). Imaging review showed that AVHR, KCA, ISH, VWA, DA, and PFDD significantly improved at 1 week, 3 months and last follow-up ( P<0.05). There was no significant difference between different time points after operation ( P>0.05). At last follow-up, according to the modified Brantigan score, all patients achieved good intervertebral bone fusion, including 22 complete fusion and 6 good intervertebral fusion with a few clear lines. No complications such as internal fixation failure or kyphosis occurred during follow-up. Conclusion: The injured vertebra fixation with inclined-long pedicle screws combined with interbody fusion is an effective treatment for thoracolumbar fracture dislocation with disc injury, which can correct the fracture dislocation, release the nerve compression, restore the injured vertebral height, and reconstruct spinal stabilization.
