Spectrum of neurosurgical operative interventions at the regional centre for neurosurgery UDUTH Sokoto: a 5 years review

Background: Neurosurgical operative interventions are aimed for the diagnosis and treatment of diseases of the central and peripheral nervous systems. The spectrum of these interventions ranges from cranial, spinal and peripheral interventions, and could also be elective or emergency based on the urgency of the intervention. Data on the spectrum of neurosurgical operative interventions are limited in our environment. The aim of the study is to describe the epidemiological profile, diagnoses and pattern of neurosurgical operative interventions at our center. Methods: This is a retrospective study analyzing the demographic profile, clinical diagnoses and operative interventions of neurosurgical patients managed at our center over a period of 5 years, from January 2014 to December 2018. Results: A total of 784 patients had operative interventions during the study period. Five hundred and twenty (520) patients were males representing 66.3%; paediatric patients accounted for 487 patients (62.1%). Majority of the patients (518 patients: 66.1%) had elective interventions. The commonest indication for neurosurgical intervention during the study period was Neurotrauma (235 patients: 30%), followed by hydrocephalus (218 patients: 27.8%) and then neurooncology (137 patients: 17.5%). Ventriculoperitoneal shunt (218 patients: 27.8%), excision and repair of myelomeningocoele (107 patients: 13.6%) and debridement/elevation for open head injury/ elevation of depressed skull fracture (85 patients: 10.8%) were the commonest operative interventions during study period. Conclusions: Although Ventriculoperitoneal shunt and excision and repair of myelomeningocoele were the commonest operative neurosurgical intervention during the study period, neurotrauma cases constituted the commonest indications for operative surgical intervention.

Advances in the Application of Bone Transport Techniques in the Treatment of Bone Nonunion and Bone Defects.

Bone nonunion and bone defects frequently occur following high-energy open injuries or debridement surgeries, presenting complex challenges to treatment and significantly affecting patients' quality of life. At present, there are three primary treatment options available for addressing bone nonunion and bone defects: vascularized bone grafts, the Masquelet technique, and the Ilizarov technique. The Ilizarov technique, also known as distraction osteogenesis, is widely favored by orthopedic surgeons because of several advantages, including minimal soft tissue requirements, low infection risk, and short consolidation time. However, in recent years, the application of the Masquelet technique has resulted in novel treatment methods for managing post-traumatic bone infections when bone defects are present. Although these new techniques do not constitute a panacea, they continue to be the most commonly employed options for treating complex large bone nonunion and bone defects. This review evaluates the currently available research on the Ilizarov and Masquelet bone transport techniques applied at various anatomical sites. Additionally, it explores treatment durations and associated complications to establish a theoretical foundation that can guide clinical treatment decisions and surgical procedures for the management of bone nonunion and bone defects.

Prediction of late results of surgical treatment of traumatic retina detachment in eye injury of multiple origin

Purpose. To evaluate the possibility of predicting the anatomical and functional results of surgical treatment of traumatic retinal detachment (RD) in trauma of various geneses, taking into account the clinical picture and the severity of the proliferative syndrome based on large clinical data.Materials and methods. A comprehensive analysis of the clinical picture (using 22 features) and long-term results of surgical treatment of 427 patients with traction traumatic RD (TRD) after open and closed eye injury was carried out. The patients were divided into 7 groups depending on the mechanism of injury. The observation period was 5 years.Results. The most severe proliferative syndrome was observed in TRD after an open injury: OEI A (contusions with scleral rupture), OEI D (double puncture wound) and OEI E (explosive trauma with scleral rupture), when both the process of mooring and PVR are present, as well as with CEI A (contusion) in the event that after the first operation PVR continued to progress. We found a direct dependence of PVR activity in TRD on the area of the detached retina and the presence of a traumatic cataract, and the inverse dependence on the presence of intraocular foreign body (IFB), its size and the ability of IFB to cause metallosis. A direct dependence of long-term functional results of treatment on the PVR stage, the area of detached retina and the diagnosed retinal rupture during the first vitreoretinal surgical intervention was established.Conclusion. In order to make the surgical treatment of TRD more effective, it is worth using antiproliferative drugs intravitreally during vitreoretinal surgery, especially in OEI A, OEI D and OGI E, when the proliferative syndrome is caused both by PVR and mooring, as well as in CEI A in the case of a pronounced PVR stage.

Diagnostic and therapeutic work-up of infected tibial nonunion

The failure of bone fracture healing is one of the major complications of fracture treatment, especially of the tibia due to its limited soft tissue coverage and high rate of open injuries. Although implant development is constantly progressing and modern surgical techniques are continuously improving, infected tibial nonunion plays adecisive role in terms of its variable clinical presentation. This article provides guidelines for the successful surgical treatment of infected tibial nonunion. Strategies are presented to identify infection as acause of failure of fracture healing and to achieve infection and bone healing. Asignificant amount of tibial nonunions primarily thought to be aseptic ultimately turn out to be infected nonunions. The treatment of infected tibial nonunion requires extensive clinical, radiological and laboratory diagnostics as well as aprofound biomechanical and biological understanding of the bone situation. This is the only way to achieve rapid osseous healing with as few revision interventions as possible.

Infectious complications in pediatric traumatology and orthopedics (analysis of clinical series)

BACKGROUND: Infectious complications in pediatric traumatology and orthopedics are relatively rare. Publications on this issue are less common than in the adult population. However, the resulting complications often lead to a persistent anatomical and functional defect, bearing the economic burden and legal consequences.
 AIM: To analyze a clinical series of pediatric patients with infectious complications of injuries and surgical interventions in the skeletal system.
 MATERIALS AND METHODS: A retrospective analysis of the clinical series of patients over 5 years was conducted. The study involved children aged 18 years. A sample of 34 children was included. The average age was 13.5 (minmax, 417 years). Patients with infectious and inflammatory complications after mechanical and/or surgical trauma, availability of a complete data archive (anamnesis, radiation therapy, and medical documentation), traced relief of inflammatory phenomena, and achievement of remission of the chronic process for more than 6 months were included.
 RESULTS: Infectious complications of injuries were noted in 26 (76%) patients, complications of orthopedic interventions in 8 (24%), and open injuries in 9 (34%). The injuries were isolated in 11 (42%) children, multiple trauma in 5 (19%), and combined in 10 (39%) patients. Defects of large skeletal segments were common: the thigh in 8 (24%) patients, humerus in 5 (15%), shin in 5 (15%), and spine in 4 (12%). Five (15%) had infection of the pelvic bones, and one patient had infectious complications in the lower jaw, collarbone, elbow joint, knee joint arthritis, and foot bones. Superficial infection of the surgical intervention area was noted in 3 cases (9%), deep infection in 27 (79%), and posttraumatic osteomyelitis in 4 (12%). The average duration of the diagnostic pause was 33 days, and the therapeutic pause was 36 days. Antibacterial prophylaxis before surgery for closed injuries and orthopedic operations was carried out in only 17 patients. Bacteriological verification was not performed in 8 (23.5%) patients with complications. In 9 (26%) patients, it was not possible to identify a microbial agent in the presence of a clinical picture. The structure of pathogens correlates with the literature data on the problem in the adult population. In 10 out of 25 positive bacteriological studies, polyresistant strains were isolated. Thirty-three children underwent surgery, and the basic principle is radical surgical rehabilitation. The average number of interventions performed was 3 (minmax, 112). Stable relief of the infectious and inflammatory process has been achieved in all cases. The average period of inpatient treatment was 39 days, recovery was achieved in 24 (71%) children, and persistent anatomical and functional defect and disability were noted in 10 (29%) children.
 CONCLUSIONS: Infectious complications in pediatric traumatology should be considered a complex multidisciplinary problem, and part of the solutions largely lies in the field of healthcare organization, specifically with an adequate choice of indications, compliance with the osteosynthesis technique, compliance with the principles of antibiotic prophylaxis, patient routine, and training of pediatric surgeons and orthopedic traumatologists on surgical infections, using modern principles and technologies for the treatment of these complications.

Cost analysis and clinical outcomes of anatomic pre-contoured locking versus conventional plates for distal fibula ankle fractures.

To analyze differences in union, complication rates and cost from surgical fixation of distal fibula fractures with fibular plating implants. In total, 380 adult patients from 2012 to 2015 treated with 12 fibular plates from 4 different manufacturers utilized by 9 surgeons were retrospectively reviewed. They were stratified into a conventional one-third tubular fibular plate group, pre-contoured anatomic locking plate group, or a heterogeneous group including 3.5-mm reconstruction, one-third tubular locking, composite, and limited compression plates. The outcomes included failure of fixation, deep infection requiring debridement, time to union, anatomic reduction, superficial infection, hardware removal, and post-traumatic arthritis. Plate and screw costs were calculated from hospital billing records. Pre-contoured locking plates were used in older, female patients with a greater number of comorbidities. Open injuries and OTA 44B fractures were more likely to be an indication for pre-contoured plates. There was no difference noted in time to union between the different plating groups. Risk factors for deep infection requiring debridement included a history of tobacco use, open fractures, and pre-contoured locking plates relative to the conventional plating group. The pre-contoured plating group was on average $586 more expensive compared to the conventional group. Pre-contoured locking plates achieved similar radiographic outcomes compared to conventional plates with an increased risk of complications and higher cost. Surgeons should consider their choice of implant based on the patient's fracture pattern, underlying comorbidities, and risk for infection.

Perilunate Dislocations: Reduction and Stabilization.

The all-dorsal scapholunate reconstruction technique is indicated for the treatment of scapholunate injuries in cases in which the carpus is reducible and there is no arthrosis present. The goal of this procedure is to reconstruct the torn dorsal portion of the scapholunate ligament in order to stabilize the scaphoid and lunate. A standard dorsal approach to the wrist, extending from the third metacarpal distally to the distal radioulnar joint, is utilized. The extensor pollicis longus is transposed and retracted radially, and the second and fourth extensor compartments are retracted ulnarly. A Berger ligament-sparing capsulotomy is utilized to visualize the carpus. Volarly, an extended open carpal tunnel release is also utilized to relieve any median nerve compression and to aid in reduction. The contents of the carpal tunnel can be retracted radially, allowing for visualization of the carpal bones. Joystick pins are placed in order to reduce the scaphoid and lunate. Reduction is held provisionally by clamping the pins until 4 pins can be placed across the carpal bones. For scapholunate reconstruction, 3 holes are made: in the lunate, proximal scaphoid, and distal scaphoid. Suture tape is then utilized to hold the scaphoid and lunate in their proper position. The dorsal wrist capsule and extensor retinaculum are repaired during closure. The pins are cut near the skin and are removed in 8 to 12 weeks. Several other methods of scapholunate reconstruction have been described, including capsulodesis, tenodesis, and bone-tissue-bone repairs. Additionally, in patients who are poor candidates for scapholunate reconstruction, wrist-salvage procedures can be utilized as the primary treatment. Scapholunate reconstruction has the advantage of preserving the native physiologic motion of the wrist, in contrast to the many different wrist-salvage procedures that include arthrodesis or arthroplasty. Avoiding arthrodesis is specifically advantageous in patients who have not yet developed arthrosis of the wrist bones. Outcomes of scapholunate reconstruction vary widely; however, there is a nearly universal decrease in range of motion and strength of the wrist. Wrist range of motion is typically 55% to 75% of the contralateral side, and grip strength is typically approximately 65% of the contralateral side. In a prior study, 50% to 60% of patients whose work involved physical labor were able to return to their same level of full-time work. Disabilities of the Arm, Shoulder and Hand scores average between 24 and 30. Specific patients at risk for inferior outcomes are those with delayed surgical treatment, poor carpal alignment following reduction, or open injuries. Patients are counseled preoperatively regarding the likelihood of permanent wrist stiffness and the possibility of scapholunate diastasis even in the setting of technically successful repair.Traction and dorsally directed pressure on the lunate through an extended carpal tunnel incision can aid in reduction of the lunate.The joystick pin position in the dorsal scaphoid is angulated from distal to proximal and that in the lunate is angulated from proximal to distal in order to help correct flexion of the scaphoid and extension of the lunate by clamping together the Kirschner wires. Modifying the distance of the clamp from the carpus can allow precision in the degree of scapholunate angle fixation.Intercarpal Kirschner wire fixation of the scapholunate, lunotriquetral, and midcarpal joints (scaphocapitate and triquetrohamate) is best performed with 0.062-in (1.6-mm) Kirschner wires. The insertion angle is best visualized when the Kirschner wire is introduced from inside the incision through the skin, "inside out," in order to best envision the trajectory on the dorsal carpus and define the starting point on the bone. The Kirschner wire is then advanced through the carpus from outside-in at a slightly more volarly translated (but not angulated) position. The Kirschner wires are then cut beneath the skin at a depth that will allow them to be retrieved but will not cause them to become exposed once swelling decreases.The wrist is generally immobilized until the pins are removed at 3 months postoperatively.

SOME OPTIONS OF FETAL TOPOGRAPHY OF THE LONG BRANCHES OF THE CROSS PLEXUS

In the conditions of wartime, the frequency of damage to the nerves of the lower extremity increased sharply. Open injuries make up the vast majority of peripheral nerve injuries. Understanding variations in the topography and the condition of the surrounding soft tissue structures allows for a detailed assessment of the condition of the peripheral nerves of the lower limb, to diagnose the exact site of damage, the type of neuropathy, and to choose treatment and rehabilitation tactics. The purpose of the study will be to establish variants of the fetal topography of the long branches of the sacral plexus. The material for the study of topographical and anatomical features of the long branches of the sacral plexus was 26 human fetuses of 5-7 months. The sciatic nerve is the largest nerve in humans, originating from the ventral division of spinal nerves L4 to S3 and containing fi bers from both the posterior and anterior lumbosacral plexuses. The sciatic nerve runs along the entire back surface of the lower limb up to the foot. The sciatic nerve innervates a signifi cant part of the skin and muscles of the thigh, lower leg, and foot. It was established that the long branches of the sacral plexus can be subjected to compression or damage in diff erent parts of its anatomical course. Among the variants of the anatomical variability of the long branches of the sacral plexus, the topography of the sciatic nerve is the most common. In the three studied fetuses of 180.0 mm, 215.0 mm, 255 mm TKD, a high branching variant of the sciatic nerve was detected, and the features of the long branches of the sacral plexus in the specifi ed fetuses were unilateral. In this case, when assessing clinical symptoms, practicing doctors should take into account options for bilateral asymmetry. Prospects for further research. Deepening the study of the variant anatomy of the long branches of the sacral plexus in human fetuses of diff erent ages.

The epidemiology of crib-related head injuries: A ten-year nationwide analysis

IntroductionFalls from cribs resulting in head injury are understudied and poorly characterized. The purpose of this study was to advance current understanding of the prevalence, descriptive characteristics of injury victims, and the types of crib fall-related head injuries (CFHI) using queried patient cases from the National Electronic Injury Surveillance System (NEISS) database. MethodsUsing the US Consumer Product Safety Commission's System NEISS database, we queried all CFHIs among children from over 100 emergency departments (EDs). Patient information regarding age, race, sex, location of the incident, diagnoses, ED disposition, and sequelae were analyzed. The number of CFHI from all US EDs during each year was also collected from the database. ResultsThere were an estimated 54,799 (95% CI: 30,228–79,369) total visits to EDs for CFHIs between 2012 and 2021, with a decrease in incidence of approximately 20% during the onset of the COVID-19 pandemic (2019: 5616 cases, 2020: 4459 cases). The annual incidence of injuries showed no significant trend over the 10-year study period. An available subset of 1782 cases of head injuries from approximately 100 EDs was analyzed, and 1442 cases were included in final analysis. Injuries were sorted into three primary categories: unspecified closed head injury (e.g., closed head injury, blunt head trauma, or traumatic brain injury), concussion, or open head injury and skull fracture. Unspecified closed head injuries were the most common of all head injuries (95.4%, 1376/1442). Open head injuries (14/1442, 0.97%) and concussions 3.6% (52/1442, 3.6%) were rare. Most injuries involved children under the age of 1 (42.6%) compared to children who were 1, 2, 3, or 4-years old. About a fourth of patients had other diagnoses in addition to their primary injury including scalp/forehead hematomas, emesis, and contusions. Female patients were more likely to present with other diagnoses in addition to their primary head injury (Difference: 12.3%, 95% CI: 9.87%–15.4%, p < .0001). ConclusionDespite minimum rail height requirements set by the Consumer Safety Product Commission (CPSC), head injuries associated with crib falls are prevalent in the United States. However, most injuries were minor with a vast majority of patients being released following examination and treatment.

Identifying risk factors for osteonecrosis after talar fracture.

To identify patient, injury, and treatment factors associated with development of avascular necrosis (AVN)following talar fractures, with particular interest in modifiable factors. Retrospective chart review. 21 US trauma centers and 1 UK trauma center. 2,220 patients with talar neck and/or body fractures. Open reduction internal fixation of talar neck and body fractures. Development of AVN. Infection, nonunion, and arthritis were secondary outcomes. 796 patients (408 M; 388 F; age 18-81, avg 38.6) with 796 (532R; 264L) fractures were included and were classified as Hawkins 1(51), IIA(71), IIB(113), III(158), IV(40), neck plus body (177), body (188). 336/798 developed AVN (42%), more commonly following any neck fracture (47.0%) vs isolated body fracture (26.1%, p<0.001). More severe Hawkins' classification, combined neck and body fractures, body mass index (BMI), tobacco smoking, right-sided fractures, open fracture, dual anteromedial and anterolateral surgical approaches, and associated medial malleolus fracture were associated with AVN. After multivariate regression, fracture type, tobacco smoking, open fractures, dual approaches, age, and BMI remained significant.Excluding late cases (>7 days), time to joint reduction for Hawkins type IIB-IV neck injuries was no different for those who developed AVN or not. AVN rates for reduction of dislocations within 6 hours of injury vs >6 hours were 48.8% and 57.5%, respectively. Complications included 60 (7.5%) infections and 70 (8.8%) nonunions. 42% of all patients developed AVN, with talar neck fractures, more displaced fractures and open injuries having higher rates. Injury-related factors are most prognostic of AVN risk. Surgical technique to emphasize anatomical reduction, without iatrogenic damage to remaining blood supply is essential. Prognostic Level III.

Effect of Calcitriol and Vitamin D Receptor Modulator 2 on Recovery of Injured Skeletal Muscle in Wistar Rats.

Muscle injuries often result in functional limitations due to insufficient healing. This study assessed the influence of calcitriol and vitamin D Receptor Modulator 2 (VDRM2) on muscle regeneration in male Wistar rats following open blunt muscle injury. The injured left soleus muscle of the rats was treated for the first four days after trauma with local injections of either calcitriol, VDRM2, or a 10% ethanol solution (control). Although muscle strength significantly decreased post-injury, all groups showed gradual improvement but did not achieve full recovery. By the 14th day, calcitriol-treated rats significantly outperformed the control group in the incomplete tetanic force, with VDRM2-treated rats showing muscle strength values that fell between the control and calcitriol groups. Similar trends were observed in complete tetanic contractions and were confirmed histologically via muscle cell width quantification. Additionally, histological analysis showed increased cellular turnover on the fourth postoperative day in the calcitriol group, as indicated by elevated cell proliferation rates and fewer apoptotic cells. VDRM2-treated animals showed only an increased proliferative activity on day 4 after injury. No noticeable differences between the groups for CAE-positive cells or visible muscle tissue area were found. In conclusion, predominantly calcitriol positively influenced post-trauma muscle recovery, where VDRM2 had substantially lower biological activity.

The continuous treatment of anterior segment open globe injury: an eye injury vitrectomy study.

The prognostic significance of debridement has long been demonstrated for trauma in tissues other than ocular. Unfortunately, the impact of wound healing in the anterior segment (AS) was not paid as much attention as in the posterior segment (PS). This study aims to evaluate whether a better prognosis can be obtained from continuous surgical treatment (CST) before fibrosis or scar formation in an open AS injury. In this prospective comparative cohort study, 19 eyes of 19 patients with an experience of AS open globe injury (OGI) were selected from the database of the eye injury vitrectomy study (EIVS) from January 1, 2020 to July 31, 2021. Of 19 patients, 9 who received CST were assigned to group 1, and 10 patients without CST after the initial wound repair were included in group 2. Comparison between the two groups was conducted in the final best corrected visual acuity (BCVA). Significant AS complications after injury were evaluated with χ2 test. The corneal leucoma area ratio, astigmatism, and the score of AS abnormalities were analyzed using the Student's t-test. The differences of baseline clinical factors between the two groups were not statistically significant. The final BCVA was better in group 1 than in group 2 (P=0.011). The complications directly caused by AS injury, namely adhesive corneal leucoma, uneven anterior chamber, block of light passing through the pupil, and fibrosis or scarring, were more frequent in group 2 than in group 1 (P=0.011, 0.022, 0.037, and 0.040, respectively). Secondary glaucoma (3 cases) and severe AS structure destruction (2 cases) occurred only in group 2 (P=0.037 and 0.474, respectively). The area ratio of leucoma (0.79±0.44, 0.82±0.50, respectively) and corneal astigmatism (3.69±1.90, 4.50±4.80, respectively) revealed no statistical significance between the two groups. On the other hand, the score of AS abnormalities, mean values being 93.33±11.18 for group 1 and 67.00±29.46 for group 2, was statistically different (P=0.022). Initiating CST before fibrosis or scar formation might improve the prognosis of open AS injury, which was preferable to natural wound healing after wound repair.

Management of open fractures: A narrative review

Open fractures are an emergency where the principal aim of the treatment is to maximise the restoration of limb function while preventing the dreaded consequences of infection and non-union. The decision-making process for open injuries is influenced by a variety of criteria, such as patient age, injury features, systemic response, activity level, comorbidities, and functional requirements. A collaborative orthoplastic approach to treating these injuries is essential for minimizing complications and need to be considered as a single specialty in early and long-term management. It has been shown that early prophylactic systemic antibiotics, wound irrigation, aggressive debridement of contaminated and devitalized tissue, and appropriate fracture fixation decreases the complications in all grades of open fractures. The advantages of Gram-negative antibiotics, the use of local antibiotics, intraoperative wound cultures, the "fix and flap" approach, and Negative Pressure Wound Therapy are few of the treatment options that are still controversial. The aim of this review is to provide a comprehensive review and practice guidelines regarding the management of open fractures.

Anterolateral and Medial Locking Compression Plates for the Management of Distal Tibial Fractures: A Comparative Prospective Study.

Open/close reduction (OR/CR) and internal fixation (IF) of displaced fractures of distal tibia with either a medial or anterolateral plate is a commonly performed procedure. Anterolateral plating avoids an incision along the medial subcutaneous border of tibia and has been shown to have reduced risk of wound complications. The aim of our study was to determine the functional outcome of these fractures treated with anterolateral and medial distal tibial locking compression plates. This was a prospective study that included 60 patients with distal tibial fractures (close or grade I open injury)divided into two groups with 30 patients in each where one group was treated with OR/CR and IF using an anterolateral distal tibial locking plate (Group A) and the other using a medial distal tibial locking plate (Group B). The duration of surgery and intraoperative blood loss and time to union were recorded for all the patients. Functional evaluation was done at one year in terms of pain, function and alignment using theAmerican Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale, and complications, if any, were noted. Both the groups were comparable in terms of age, gender, time of presentation, AO classification and presence of wound. The mean duration of surgery as well as the intraoperative blood loss were more in the anterolateral plate group than in the medial plate group, but the difference was statistically insignificant. Ten patients (33%) with medial plates had symptomatic hardware and 7 (23.3%) underwent removal while only 3 (10%) patients in the anterolateral plate group had similar complaints and none had to undergo removal. Two patients with anterolateral plate and one with medial plate had malunion. The mean time to fracture union as well as the rate of infection was less and the functional outcome at one year was better in the group treated with anterolateral plates as compared to the one with medial plates, but the difference again was not statistically significant for all the parameters. With reduced risk of soft tissue complications and by obviating the need for implant removal, anterolateral plates can prove to be a better alternative to the medial plates especially in elderly patients in the management of these fractures.

Surgical and Functional Outcomes of the Results of Conventional Two-Screw Proximal Femoral Nail (PFN) Versus Helical-Blade Anti-rotation Proximal Femoral Nail (PFNA2).

Introduction An intertrochanteric (IT) femur fracture is an extra-capsular fracture between greater and lesser trochanters. Unstable IT fractures are those where there is poor contact between fracture fragments (especially medial and posterior cortices), comminution, and fracture pattern, such that the weight-bearing forces tend to displace the fracture further or a reverse oblique type. Proximal femoral nailing (PFN) is one of the modalities for proximal femoral fractures. A newer modality for proximal femoral fracture is PFNA2, i.e., PFN anti-rotation, which makes use of a helical blade for a better compaction of bone. Both nail designs (PFN and PFNA2) are available in short and long sizes (so a total of four variants). Only a few studies have compared the treatment of IT femur fracture concerning fracture geometry, design, and length using either of the two nail types. In our study, we assessed the surgical and functional outcomes of PFN and PFNA2. Materials and methods This prospective observational study was carried out on 30 patients who had sustained ITfractures of the femur. All cases of IT femur fractures more than 18 years of age, closed injuries, and the patients who consented to participate in this program were included in the study. All open injuries, the patients who refused to participate in this program, patients who have associated injuries, patients with a subtrochanteric femur fracture, and patients with less than six months of follow-up were excluded. The patients were randomized into two types of implant groups. All patients were operated with a standard protocol. The study was conducted for18 months from February 2021 to August 2022. The results were analyzed (of all four variants) by comparing patient demographics, implant size, implant type, locking methods, union time, and other parameters. Results Most of the patients were operated on with a 10 mm nail diameter (17/30 patients), 380 mm length (long-nail group) (five/11 patients), and 250 mm length (short-nail group). With the use of PFNA2, the overall duration of hospital stay was less. The overall operative time (incision to wound closure) with the use of the short PFNA2 was lesser than that with the use of other designs due to the use of the zig for distal screws. The use of a distal dynamic locking screw in a majority of the patients can get better compression at the fracture site once the patient starts weight bearingand decreasethe chances of the Z-effect, reverse Z-effect, screw back-out, and screw cut-out. The union time was nearly the same in the majority of the patients, with an early union seen with the use of PFNA2 nails. The overall modified Harris hip score (HHS) at the final follow-up was nearly the same with slightly better results with the use of PFNA2. Conclusions PFNA2 is the implant of choice in elderly patients with osteoporotic bone. It has less operative time, which is required in such patients with medical comorbidities; hence, it has marginal superiority over PFN. Short-nail design results in less operative time and less blood loss.

Metabolic abnormalities underlying nonunion in the adult fracture patient

Introduction: The objective of this study is to comprehensively evaluate fracture type, category of nonunion, and metabolic profile to identify metabolic causes that may impact fracture union. Methods: A retrospective chart review of patients diagnosed with nonunion after fracture fixation was performed. Patient demographics, fracture characteristics, and metabolic profiles were assessed. Results: Data was collected from 94 patients with nonunion, with a mean age of 54.7 years, 50% men, 47.3% obese, and 60.8% current/former smokers. The most common nonunited bone was the femur (48%), tibia (22%), humerus (15%), ulna (5%), clavicle (3%), and fibula (2%). The distal femur, femoral shaft, and tibial shaft made up 50% of the nonunion. The intra-articular fracture was diagnosed in 13% and open injuries in 27%. The most common metabolic abnormalities were low hemoglobin (62.3%), elevated neutrophil percentage (61.9%), elevated erythrocyte sedimentation rate in women (51.8%), low testosterone (46.9%), and hypovitaminosis D (44.3%). Conclusion: The prevalence of metabolic abnormalities was documented across all nonunion types, suggesting this is not unique to atrophic nonunion. Given the high morbidity and cost of nonunion, and low cost of vitamin supplementation, future prospective studies are warranted to identify effective prevention and treatment.

INCLUSION OF OPEN INJURIES IN AN UPDATED SCHENCK CLASSIFICATION OF KNEE DISLOCATIONS BASED ON A GLOBAL DELPHI CONSENSUS STUDY

AbstractIntroductionKnee dislocations (KDs) are complex injuries which are often associated with damage to surrounding soft tissues or neurovascular structures. A classification system for these injuries should be simple and reproducible and allow communication among surgeons for surgical planning and outcome prediction. The aim of this study was to formulate a list of factors, prioritised by high-volume knee surgeons, that should be included in a KD classification system.MethodsA global panel of orthopaedic knee surgery specialists participated in a Delphi process. A list of factors to be included in a KD classification system was formulated by 91 orthopaedic surgeons, which was subsequently prioritised by 27 experts from 6 countries. The items were analysed to find factors that had at least 70% consensus for inclusion in a classification system.ResultsThe four factors that reached consensus agreement and thus deemed critical for inclusion in a classification system were vascular injuries (89%), common peroneal nerve injuries (78%), number of torn ligaments (78%), and open injuries (70%).ConclusionThe wide geographic distribution of participants provides diverse insight and makes the results of the study globally applicable. The most important factors to include in a classification system as determined by the Delphi technique were vascular injuries, common peroneal nerve injuries, number of torn ligaments, and open injuries. The Schenck anatomic classification system most accurately identifies these patient variables with the addition of open injuries. The authors propose to update the Schenck classification system with the inclusion of open injuries as an additional modifier.

Spontaneous closure of transverse loop colostomy: A case report

Colostomy is an artificial colo-cutaneous fistula which can be temporary or permanent, depending on the purpose for which it was created. The indications for colostomy include protection of a distal intestinal anastomosis, control of sepsis in open injury to the colon or rectum, to facilitate the operative treatment of a high anal fistula

Neuron Specific Enolase Levels’ Relationship with CT Scan Images on Head Injury Patients

Head injuries can cause closed injuries, or open injuries that can penetrate the skin, starting from the skin as the outermost layer, to the bones of the skull, blood vessels of the brain, and brain tissue as cranio-cerebral injuries. The authors wanted to prove whether there is a picture between NSE serum levels and a CT scan of the head that describes the severity of a head injury. The type of research used in this research is analytic observational research. The study design in this study was a cross sectional which aims to describe the levels of Neuron Specific Enolase (NSE) serum with CT scan images of head injured patients at RSUP Dr. M. Djamil City of Padang. This research was conducted in the Emergency Room of RSUP Dr. M. Djamil, Padang City as the sampling location and the Biomedical Laboratory of the Faculty of Medicine, Andalas University as the research location and the research time starts from February to June 2023. Head injury patients who underwent head CT scans at the M.Djamil Hospital Padang Emergency Room were found with the following characteristics: age 20-29 years, male sex, CT scan of the head in the form of MLS&lt;5mm/cistern narrowing, increased NSE level, severity mild head injury (GCS 13-15).

Risk factors of elbow stiffness after open reduction and internal fixation of intercondylar fracture of humerus

To investigate the risk factors of elbow stiffness after open reduction and internal fixation of intercondylar fracture of humerus. From March 2015 to February 2019, 120 patients with humeral intercondylar fractures were treated with open fixation including 59 males and 61 females, aged from 25 to 77 years with an average of(53.5±3.2) years. According to the occurrence of elbow stiffness after operation, 120 patients were divided into stiffness group(37 cases) and control group(83 cases). The related factors of elbow stiffness were analyzed by single factor analysis, and the risk of elbow stiffness after internal fixation of humeral intercondylar fracture was analyzed by logistic regression factor. There were 37 cases of elbow stiffness(stiff group), and 83 cases had no elbow stiffness(control group). The incidence of joint stiffness was 30.83%. There were significant differences between the stiffness group and the control group in age, injury energy, fracture to operation time, AO classification of fracture, open injury and postoperative premature or hyperactivity. Multivariate logistic regression analysis showed that age>50 years old, high energy injury, AO classification of fracture, open fracture and postoperative premature or hyperactivity were risk factors for elbow stiffness after internal fixation of humeral intercondylar fracture. The postoperative mobility and Mayo elbow performance score(MEPS) scores of the postoperative stiffness group were lower than those of the non-stiffness group with statistical significance(P<0.05). There were no significant differences in postoperative mobility and MEPS scores between flexion stiffness and rotation stiffness after humeral intercondylar fracture(P>0.05). In view of the risk factors of elbow stiffness after internal fixation of humeral intercondylar fracture, reasonable operation plan and rehabilitation strategy should be formulated before operation to minimize the incidence of elbow stiffness.
