Traumatic Native Hip Dislocations: An Audit at a Major Trauma Centre and Assessment of Clinical Practice at Centres Across the United Kingdom.

Native hip dislocations are defined as traumatic dislocations of the hip, typically high-energy and associated with polytrauma. The majority of these injuries occur following motor vehicle accidents (MVAs). Due to the inherent stability of the hip joint, a significant force is required to cause dislocation. It is critical that such injuries are managed and reduced in a timely manner. We evaluated the current practice in a major trauma centre (MTC) in Cardiff and gathered information from emergency departments (EDs) in Wales and MTCs around the United Kingdom (UK). We did an evaluation of the current practice with a retrospective audit of all traumatic native hip dislocations presenting to the MTC at Cardiff from August 2018 to February 2021. Data was obtained from Trauma Audit and Research Network (TARN), medical records, radiology and theatre management systems. An online survey was developed and disseminated to EDs in Wales and MTCs across the UK. There were 15 traumatic hip dislocation cases over the period evaluated. Sixty percentof cases were due to MVA. Eighty-six percent of patients had an associated fracture, with one Pipkin type IV fracture dislocation. The mean time to reduction from injury was 532 minutes (240-804 minutes), with 28.6% reduced within 6 hours and 71.4% reduced within 12 hours. Two patients had reduction performed in the ED (mean time to reduction, 275 minutes). There was one occurrence of avascular necrosis (AVN) and one of chondrolysis at the follow-up. The response rate to the survey was 80% and 83% in Wales and MTCs nationally, respectively. The majority (82%) of departments did not have an established pathway in place for managing traumatic native hip dislocations with a preference for reduction in the operating theatre. Native hip dislocations are rare, high-energy injuries associated with significant morbidity. The available evidence suggests time to reduction is imperative in reducing the risk of future complications. The establishment of a pathway to guide management and having a mechanism to perform reductions in the ED may produce significant reductions in this time, impacting outcomes.

Support from advanced practitioners in critical care for ankle fracture dislocation

Background: Analgesic imitations, under-recognition of injury severity and delayed restoration of neutral alignment are common problems around ankle fracture dislocation (AFD). Optimal prehospital management improves long-term outcomes. Aims: This study aimed to explore ambulance clinicians' experiences of AFD incidents when supported by advanced practitioners in critical care (APCCs). Methods: Semi-structured online interviews were conducted. Data sets were coded and grouped to identify themes via thematic content analysis. Findings: Six clinicians agreed to take part (response rate 42%). AFDs were encountered infrequently (once per year). Four themes were identified: clinicians' confidence in managing AFD; value-added role of APCCs; prehospital challenges; and reflections on the incident. Conclusions: Benefits of the APCC role include enhanced technical skills, including in ankle reduction and analgesia, and in non-technical skills, such as leadership and decision-making. Improvements in clinician recognition and management of AFD and better awareness of the APCC role are recommended, as is research on optimal prehospital AFD management.

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

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 VAIin 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 ofinjury, 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, Indiafrom 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. 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. 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 angiographyfor confirmation. Proper pre-operative evaluation of vascular injury in cervical spine fracture dislocation is very important for patient counseling, patient management, and surgical planning.

Deformation Behavior and Fracture Strength of Single‐Crystal 4H‐SiC Determined by Microcantilever Bending Tests

In this study, the deformation behaviors and mechanical properties of 4H‐SiC single crystals are investigated using microcantilever beam specimens with two different sizes, A and B (A &lt; B). Tensile stress is applied along &lt;20&gt; direction. Plastic deformation, or nonlinearity, is observed in the stress–strain curves, and yield stress, or proportional limit, coincides between the two specimens at ≈25 ± 2 GPa. Scanning transmission electron microscopy and transmission electron microscopy studies show that the plastic deformation is due to dislocation activities; multiple‐dislocation pileup areas are observed in both the specimens. Assuming {100}/&lt;110&gt; prismatic slip which most plausibly occurs in the &lt;20&gt; stress application, the critical resolved shar stress is estimated to be 10.9 GPa, which agrees well with the previous studies. Measured fracture strength is 41.9 ± 2.8 and 33.5 ± 2.4 GPa for the A and B, respectively. Dislocation–fracture relationship is discussed on the basis of dislocation‐based fracture mechanics, etc. It is suggested that cracks form within the multiple‐dislocation pileup area, by interaction with dislocation pileups, and act as fracture origins. A's strength is close to an ideal tensile strength of 4H‐SiC in the &lt;110&gt; direction, 47–55 GPa.

Temporary Cast Application in Dislocated Ankle Fractures Leads to High Rates of Secondary Loss of Reduction: Does the Lauge-Hansen Injury Type Matter?

For the temporary treatment of ankle fracture dislocations (AFDs), previous studies indicate higher rates of secondary loss of reduction (LOR) with splint immobilization, prompting consideration for expanding indications for external fixation (ExFix). However, these studies did not investigate the influence of fracture morphology to further improve patient selection. The aim of this study was to investigate the influence of Lauge-Hansen injury type on the LOR rate in bimalleolar or trimalleolar AFDs for temporary cast vs ExFix immobilization. In this retrospective cohort study, patients with isolated AFD cases treated at our institution from 2011 to 2020 were reviewed. Inclusion criteria required radiographs depicting initial dislocation and appropriate reduction after Cast or ExFix immobilization. Exclusion criteria encompassed concomitant injuries, open fractures, conservative management as well as surgery performed within 48 hours or at a different facility. Patients were grouped by temporary treatment (Cast or ExFix). The primary endpoint was LOR prior to definitive surgery across various Lauge-Hansen types. The LOR rate was significantly higher in the cast group (40/152, 26.3%) compared to the ExFix group (5/191, 2.6%; P < .0001). In the cast group, LOR was associated with an increase in time to definitive surgery by a mean of 3 days (P < .002). During cast treatment, LOR was significantly more likely for pronation abduction (P = .001) and supination external rotation injuries (P < .0001), whereas no significant differences were observed for pronation external rotation (P = .006), supination adduction (P > .99), and fractures not classifiable (P > .99). In cases of AFDs resulting from supination external rotation or pronation abduction trauma according to the Lauge-Hansen classification, especially in the setting of an additional posterior malleolar fracture, primary application of external fixation should be considered to reduce the risk for secondary loss of reduction. Level III, retrospective cohort study.

P35: A Systematic review on the outcomes of the reverse shoulder arthroplasty versus hemiarthroplasty for the 3- and 4- part proximal humeral fractures in the elderly population

Abstract Background The hemiarthroplasty (HA) and reverse total shoulder arthroplasty (RTSA) are common surgical methods in of the proximal humerus management, where the surgical fixation is not feasible. Our aim is to analyse the most recent data to inform choices on best management for managing 3- and 4 -part fracture dislocations of the proximal humeral fractures in the elderly population. Methods The Medline, PubMed and Scopus databases were searched in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify the relevant literature to include for analysis. The inclusion criteria involved English language, functional outcomes, revision rates, hemiarthroplasty, and reverse total shoulder arthroplasty. The exclusion criteria were publications before 2018, systematic reviews and meta-analysis, other management options such as conservative management, surgical fixation, and total anatomical shoulder replacement. Results The data collected included study design and level of evidence, number of patients and patients’ characteristics, follow-up time post-surgery, functional outcomes, range of movement, Constant score, subjective scores including Disability of Arm and Shoulder (QuickDASH) and American Shoulder and Elbow Score (ASES), and revision rates. Conclusions The evidence suggests that RTSA is the new gold standard management for 3- and 4-part fracture dislocations of the proximal humerus in a selected group of patients over 65 years old with irreparable rotator cuff. The available literature is medium quality, requiring more robust evidence including prospective large cohort studies utilising unified objective and subjective functional outcome scores.

Clinical Features and Classification of Proximal Carpal Fracture Dislocation Through the Radiocarpal Joint.

Background: The most common types of wrist dislocation are trans-scaphoid lunate dislocation (TLD) and trans-scaphoid perilunate dislocation, in which the lunate and proximal scaphoid are dislocated through the midcarpal joint. There is another rare type of dislocation in which the proximal carpi are dislocated through the radiocarpal joint. The purpose of this study is to examine the clinical features of this type of dislocation. Methods: Six cases of the proximal carpal fracture dislocation via the radiocarpal joint were retrospectively reviewed. All patients underwent open reduction and internal fixation with the ligament reconstruction. A Mayo wrist score was assigned to each patient based on the assessment of pain, functional status, range of motion and grip strength at the last follow-up. Clinical subjective evaluation of function and pain was assessed using the patient-rated wrist evaluation (PRWE) method. Results: All patients were male and injured with a median age of 33.5 years. The median follow-up period was 10 months. There were three types of dislocations: Scaphoid fracture dislocation, TLD and scaphoid-lunate dislocation. All patients had satisfactory results with an average PRWE of 7.2 ± 4.7. The preoperative VAS was 6.7 ± 1.0 and the postoperative VAS was 0.7 ± 0.7 (p < 0.01). Postoperative grip strength accounted for 89.2% ± 9.8% of the contralateral side; the Mayo wrist score averaged 90.0 ± 6.5, with four patients obtaining excellent and two good results. Conclusions: Fracture dislocation of the proximal carpal bones through the radiocarpal joint is an independent type of wrist dislocation that tends to occur in young men with high-energy impact. The wrist is most often injured in a pronation hyperextension position. If treatment is timely and appropriate, the prognosis is quite good. Level of Evidence: Level IV (Therapeutic).

Irreducible Fracture Dislocation of the Elbow Due to Medial Epicondyle Entrapment Associated with Median Nerve Palsy in Adult: A case report

Purpose: Medial epicondyle fractures are common elbow injuries in pediatric and adolescent population. However, this condition is extremely rare in adults, with only a few cases reported in the literatures. This report presents the case of an adult patient with an irreducible fracture dislocation of the elbow due to intra-articular entrapment of the medial epicondyle associated with median nerve palsy. Methods: A case of 36-year-old man presented with posterolateral fracture dislocation of the left elbow with displaced medial epicondyle and median nerve palsy. Closed reduction was attempted, resulting in a grossly unstable elbow. Post-reduction radiographic study demonstrated the articular incongruence with the entrapped medial epicondyle. The patient underwent an open reduction and median nerve exploration. A fragment of the medial epicondyle was found comminuted and repaired using our novel technique with suture anchors. The lateral ulnar collateral ligament was repaired because of varus residual instability. The dislocated elbow was successfully reduced. Results: At 6 months follow-up, the elbow was stable with nearly full range of motion, although radiographic studies demonstrated union fractures with partially fragment resorption. Both sensation and motor function of the median nerve were gradually recovered. Conclusions: We presented a novel fixation technique for a rare case of irreducible fracture dislocation of the elbow due to intra-articular entrapment of the medial epicondyle associated with median nerve palsy in adults. The median nerve should be explored in every case, and delayed diagnosis should be avoided, which may lead to devastating complications.

Traumatic gluteus maximus femoral insertion tear

With hip fracture dislocation, there is a wide variety of injuries, and one of the least and rarely to be seen is a gluteus maximus femoral insertion tear. We report this case to encourage further sharing of similar cases, establish a treatment protocol, and avoid such potential complications. We present this rare case of a 36-year-old male, a victim of a severe motor vehicle collision, who presented with a head contusion, right gluteus maximus femoral insertion tear, right hip dislocation with closed posterior wall acetabulum fracture, intra-articular incarcerated fragment, and multiple fractures. After the reduction of his hip and splinting of his concomitant fractures and optimization of the general condition, he underwent open reduction internal fixation of the posterior acetabulum wall. Intraoperatively, he found to have a rupture of gluteus maximus and short external rotators for which he had gluteus maximus direct repair to its insertion and partial repair for his severely damaged external rotators. The patient developed a surgical site infection post operation, treated by multiple sessions of irrigation and debridement and culture-based intravenous venous antibiotics for six weeks. At the 7-month outpatient clinical follow-up, the patient function was able to mobilize with a limping gait using a cane and extreme limitation of his abduction, external rotation, and extension due to the development of heterotopic ossification, which could be due to prolonged intensive care unit admission due to head injury or hip external rotators rupture or multiple surgeries that he underwent. This rare finding of gluteus maximus ruptur is the first of a kind in our institute, and such a finding to be considered before treatment of such severe injuries and questioning the need for magnetic resonance imaging for traumatic hip dislocations plus prophylactic treatment of heterotopic ossification to optimize the functional outcome post-operative.

The use of hinged elbow orthosis following surgical management of terrible triad injuries of the elbow.

To determine outcomes following surgical management of terrible triad injuries in patients treated with and without a hinged elbow orthosis (HEO) in the post-operative setting. This study was a retrospective review of 41 patients who underwent surgical treatment of terrible triad injuries including radial head fracture, coronoid fracture, and ulnohumeral dislocation between 2008 and 2023 with at least 10-week follow-up. Nineteen patients were treated post-operatively without HEO, and 22 patients were treated with HEO. There were no differences in range of motion (ROM) between patients treated with and without HEO in final flexion-extension arc (118.4° no HEO, 114.6° HEO, p = 0.59) or pronation-supination arc (147.8° no HEO, 141.4° HEO, p = 0.27). Five patients treated without HEO and one patient treated with HEO returned to the operating roomfor stiffness (26%, 5%, p = 0.08). QuickDASH scores were similar between groups (p = 0.69). This study found no difference in post-operative ROM, complications, or QuickDASH scores in patients treated post-operatively with or without HEO. Based on these results, we cannot determine whether the use of HEO adds additional stability to the elbow while initiating ROM exercises post-operatively.

An ethno-botanical survey of medicinal plants used in the treatment of fracture and dislocation in Ogugu, Kogi State Nigeria

The documented information on traditional medicinal plants in Ogugu communities of Kogi State is vague and limited to its species and thus very little research has been done on these medicinal plants. An Ethno-botanical study was conducted to take inventory of the species by the inhabitants of various communities in Ogugu, Olamaboro Local Government area of Kogi State in bone fracture treatment and dislocation. The study was carried out between May through September 2019. Ethnomedicinal knowledge was gathered from 20 traditional bone setters in 10 communities using questionnaires. The plants most referenced from the questionnaire were collected and identified using various standard methods and procedures. 80% of the respondents were male while 20% were female. 40% were in the range of 31-41 years of age and only 10% were in the age range of 20-30 years. About 45% has no formal education while only 5% had a university degree. TBS with most year of experience (21-25 years) are only 5% while the profession is dominated by those of moderate time of practice (11-15 years) with 40% representative. A total of 49 medicinal plant species distributed in 27 families and genera were documented. Family Euphorbiaceae was found to be mostly used for fracture treatment. The most frequent used plant parts were the leaves (49.5%). The method of preparation of the herbal remedies were generally best in the form of poultice administered in the form of paste to give the best result in fracture and bone setting treatment.

Functional Outcome of Peripheral Nerve Injury after Pediatric Supracondylar Humerus Fracture: Comparison of Surgical and Conservative Treatment

Supracondylar humerus fractures are the most common elbow fractures in children up to 10 years of age. The incidence of associated nerve injuries varies up to 15% depending on the data. Traumatic and iatrogenic lesions mainly affect the ulnar nerve. The regeneration of peripheral nerves is comparatively better in childhood. In the present study, the functional results after surgical and conservative treatment of nerve injuries in children after supracondylar fractures were compared and analyzed for influencing factors. In this retrospective comparative study, clinical data of pediatric nerve injuries following supracondylar humerus fractures treated over a period of 13 years (2008-2021) were analyzed. Children who were treated surgically (neurolysis, autologous reconstruction) due to insufficient clinical/neurophysiological improvement within 6 months after trauma or who were followed up conservatively in case of regression of symptoms within 6 months after trauma were included. All patients underwent multidisciplinary follow-up. 48 patients (26 female/22 male) with nerve injuries were included in this study. All patients had a history of surgical treatment with K- wire fixation due to severe dislocated fractures. The mean age was 7±2 years. The initial symptoms were severe motor deficits in all patients and sensory deficits in 87.5% (n=42). Isolated lesions of the ulnar nerve were most common (n=24, 50%). The nerve was neurolysed in 21 patients and additionally transferred to the volar side in 15. Nerve grafting was performed in 7 children and split repair in 2. Postoperatively, there was a significant improvement in motor function in all patients. Despite comparably severe motor deficits at initial presentation, further 20 children were treated conservatively due to the regression of neurological deficits. They showed comparably good functional results. No serious complications were recorded in either group. The average follow-up time was 377.25±524.87 days. The presented study shows excellent functional results after surgical treatment of pediatric nerve injuries without severe complications. Children with comparatively high-grade lesions at initial presentation have a good chance of complete spontaneous remission even without surgery. For this reason, the indication for surgery in children should be very carefully considered.

Study on Voids and Seepage Characteristics within Rock Fracture after Shear Dislocation Viewing from CT Test and Numerical Modeling

In rock mass engineering, stress balance changes often cause the relative slip of fractures along a wall surface, impacting the seepage behavior of fluid in the fractures. Using computer tomography (CT) scanning, spatial models of fractures with dislocations ranging from 0 to 10 mm were created to explore the relationship between changes in fracture dislocation and changes in fluid flow behavior, respectively. The spatial fractal dimension of cavity distribution within the fractures was calculated using a thin-plate filling approach to characterize the complexity of the fracture cavity distribution. The fluid flow within the dislocation fractures was then simulated using COMSOL, and the effect of cavity alterations in the form of dislocation on the fluid seepage behavior was analyzed using the spatial fractal. The results show that the values of mechanical aperture after dislocation of the fracture obtained by a CT test are normally distributed, the distribution range of mechanical aperture gradually widens with an increase in the dislocation distance, and the average mechanical aperture increases on a logarithmic curve. The relative spatial fractal dimension decreases gradually with an increase in dislocation distance, and the interconnected pathways within the fracture decrease; in addition, it is observed that the change in the relative spatial fractal dimension is closely correlated with the change in the mean mechanical aperture. Numerical simulations of dislocation fracture seepage found that the permeability increases nonlinearly with increasing dislocation distance. When the dislocation distance reaches 5 mm, nonlinear behaviors such as eddy currents occur, and the influence range of eddy currents gradually expands with the increase in dislocation distance under the influence of the boundary. Moreover, the inertia coefficient B in the Forchheimer equation and the critical hydraulic gradient Jc, which can describe the nonlinear seepage characteristics, show a power function decreasing trend with increasing dislocation distance, and the fluid in the fracture is more likely to produce nonlinear flow.

Comparison of Posterior Approach and Combined Anterior-Posterior Approach in the Treatment of Ankylosing Spondylitis Combined With Cervical Spine Fracture: A Systematic Review and Meta-Analysis.

Systematic review. To compare the efficacy of the posterior approach and combined anterior-posterior approach in the treatment of ankylosing spondylitis (AS) with cervical spine fracture by meta-analysis. The databases PubMed, Web of Science, Embase, and Cochrane Library were searched for studies on the comparison of the posterior approach group and the combined anterior-posterior approach group in the treatment of ankylosing spondylitis combined with cervical spine fracture from database establishment to August 2023. The procedure time, intraoperative blood loss, the rates of neurological improvement, mean change in the postoperative neurological function, complication rates, rates of revised surgery, and mortality were extracted. Meta-analysis was performed using RevMan 5.4 software provided by Cochrane Library. A total of 11 retrospective cohort studies with a total of 215 patients were included in this study. The posterior approach group had lower intraoperative blood loss than the combined anterior-posterior approach group [Mean difference (MD) = -146.05, 95%CI(-187.40,-104.69), P < .00001]; the operation time was significantly less in the posterior approach group than in the combined anterior-posterior approach group [MD = -95.34, 95%CI(-113.13,-77.55), P < .00001]. There were no statistically significant differences in the neurological improvement rates, mean changes in postoperative neurological function, complication rates, modified surgery rates, and mortality rates. Both the posterior approach and combined anterior and posterior approach can achieve good results. Clinicians should develop an individualized approach based on the patient's fracture type, degree of spinal cord injury, fracture stability, fracture dislocation, general condition, and underlying disease.

Entrapment of median nerve after elbow fracture dislocations: expected surgical time frame based on cadaver study.

Median nerve injuries occur in approximately 3% of pediatric elbow fracture dislocations. These rare injuries can be difficult to diagnose, and the results are poor in delay cases. Surgical timing is one of the most important prognostic factors. We aimed to present three patients with median nerve palsy who were referred to our clinic late, and according to these cases, we emphasized the expected time frame for exploration based on our anatomical cadaver study. Between 2008 and 2010, three patients were referred to our clinic because of median nerve paralysis after a treated elbow dislocation. The mean interval between injury and referral was 15 (min: 13-max: 18) months, and the mean age of the patients was 15 (13-18) years. Neurolysis was performed in two patients, and for the third patent, after neurolysis, axonal continuity was observed to be disrupted so sural nerve grafting was performed with four cables. Tendon transfers were performed in all patients. A total number of 20 upper extremities of 10 cadavers were dissected. Due to its proximal innervation and ease of assessment, the muscle innervation of the flexor pollicis longus (FPL) was planned to be evaluated. The distance from the medial epicondyle is calculated in the cadaver study where the nerve injury is found. The mean length from the medial epicondyle to the motor innervation of FPL was calculated in each specimen and found to be 101.99 millimeters (mm) (range: 87.5-134.2). The mean longest innervation of FPL was 110.83 mm from (range 87.5-148.1) the medial epicondyle calculated by including each specimens longest nerve length. Knowing that the healing time of a nerve lesion is 1 mm per day, we calculated that the recovery of FPL would take approximately 4 months. When nerve healing is expected to be 1 mm a day in axonotmesis type injury, after the median nerve palsy following elbow dislocation, thumb flexion should be achieved in the following 4 months generally if the nerve was not entrapped in the joint. This cadaver-based study objectively defined how long to wait for the innervation of the FPL in median nerve injuries in elbow fracture dislocations.

The 'Shish-Kebab technique' in intra-articular fractures of the hamate body and concomitant 4th metacarpal base fracture.

Hamate fractures are infrequent and often overlooked wrist injuries. Our objective is to present the Shish-Kebab method, a surgical approach utilized in the treatment of intra-articular Hamate body fractures occurring concurrently with fourth metacarpal base fractures and dislocations. This study was conducted at a single-center using a prospective design. It included patients aged 16-65 with Kim Type IIB fractures affecting the dominant side. Patients with the same features of fracture and carpometacarpal (CMC) instability findings were divided into two groups according to the success of the closed reduction procedure. In the conservative group (8 patients), all fractures and instability findings were successfully resolved with closed reduction and a short arm plaster cast. The surgical group (8 patients), comprising those requiring open reduction and internal fixation, underwent the application of the 'shish kebab' method. At the 6th and 12th week follow-ups, no significant differences were observed between the groups concerning pVAS and QuickDash scores. However, upon examining the QuickDash scores, a statistically significant difference emerged between the 6th and 12th weeks within both the conservative (p = 0.017) and surgical (p = 0.012) groups in the intragroup analysis. Grip strength, measured as 83.78% of the contralateral side in the surgical group and 79.51% in the conservative group, did not exhibit a statistically significant difference (p = 0.462). In the management of Hamate body intra-articular fractures and accompanying fourth metacarpal base fracture dislocations, good clinical results can be achieved with the 'Shish-Kebab' method in cases where closed reduction is unsuccessful.

Our experience with the surgical management of lower cervical spine fractures: fifty case series.

Trauma to the lower cervical spine is a serious lesion due to its neurological consequences which jeopardize the vital and functional prognosis. They constitute a public health problem due to their frequency and seriousness requiring rapid and adequate treatment. The aim of our study is to (1) describe the epidemiological, clinical, and radiological characteristics of lower cervical spine trauma patients; (2) support the therapeutic management of these patients and show our experience in surgery for lower cervical spine trauma; and (3) analyze the anatomical and functional results and discuss them with literature data. This is a retrospective descriptive study of 50 patients with lower cervical spine trauma treated surgically over a period of five years from January 1, 2016, to December 2020. The average age of our patients was 34.5 years, with a sex ratio of 1.7. The etiologies are dominated by accidents on public roads (58%). They show neurological disorders such as spinal cord damage in 30% of cases and root damage in 20% of cases. The radiological assessment revealed eight tear drops, ten comminuted fractures, 12 severe sprains, 12 biarticular dislocations, six uniarticular dislocations, and two herniated discs. Treatment was surgical in all patients with an anterolateral approach and anterior arthrodesis. The evolution was favourable in 21 patients and stationary in 29 patients. Our study concluded that dislocations and fracture dislocations were the predominant type of injury in cases of AVP. Tetraplegia was mainly observed with uni- and biarticular dislocations. The variation in consolidation time was not correlated with trauma-to-surgery time. Better neurological recovery was observed with mild initial neurological damage than with initially severe damage. The appearance of an adjacent syndrome is less frequent with monosegmental arthrodesis than with multisegmental arthrodesis. Cage arthrodesis was an alternative to iliac harvesting with similar results.

Outcome Analysis of Fixed angle Locking Plate in Comminuted Patella Fractures : A Single Centre Prospective study from South India with Early Results.

Comminuted patella fractures pose a challenge to orthopaedic surgeons , since tension band wiring and cerclage is not effective and often lead to loosening of wires, hardware problem, dislocation of fracture and failure of osteosynthesis resulting in post-traumatic osteoarthritis and knee stiffness. The aim of this study is to evaluate the clinical outcome in patients with AO 34C2 and 34C3 highly comminuted patella fractures treated with unidirectional fixed angle titanium patella locking plate. Twelve patients who presented with AO 34C2 and 34C3 comminuted patella fractures, aged between 18-79 years were included in the study. All fractures were reduced and fixed with unidirectional angle fixed stable titanium patella locking plate. Knee range of motion and knee outcome survey activities of daily living scale (KOS-ADL) was used to evaluate the outcome. Union of fracture was achieved in all twelve patients. Mean flexion at final follow-up was 123° (110°-130°). None of the patients had extensor lag. One patient had hardware irritation which resolved at final followup. This technique serves as an effective option in highly comminuted patella fractures by providing excellent mechanical stability resulting in anatomical reduction , excellent functional outcome , lower incidence of hardware irritation or failure of osteosynthesis.

Surgical Approach to Acute Osteochondral Fracture With Patellar Instability in Skeletally Immature Patients

Background: Patellar instability is a common condition that affects many young, active patients and can lead to long-term disability. This video aims to provide insights in the treatment of acute osteochondral fractures in skeletally immature patients after acute patellar dislocation. Indications: Patients who present with acute patellar dislocation and evidence of osteochondral fracture or osteochondral fracture with a loose body are potential candidates for medial patellofemoral ligament reconstruction (MPFLR) with osteochondral fragment fixation. Technique Description: In case 1, arthroscopy revealed a medial patellar facet defect. A medial patellar incision was made with dissection down to the vastus medialis oblique fascia and medial retinaculum. Before continuing to capsulotomy, the dissection for the MPFLR is completed by dissecting down to create a plane between layers 2 and 3. Capsulotomy is then performed with retrieval of the loose body, preparation of the patellar defect, and fixation of the osteochondral fragment. The MPFLR is then performed. An allograft is fixed to the patella with 2 pushlock anchors, and to a distally directed femoral tunnel using a 7-mm pitchfork SwiveLock tenodesis anchor, with care to avoid the medial femoral physis. The capsulotomy is then closed underneath the graft, with layer 2 closed above it. In case 2, a large osteochondral fracture of the lateral femoral condyle with loose cartilage flaps was arthroscopically identified. An anterior incision was made and a lateral lengthening was completed to perform a laterally based arthrotomy to expose the defect on the lateral femoral condyle. The defect site was prepared and the loose body was secured and fixated into the donor site lesion using bioabsorbable screws. The MPFLR was completed as in case 1, and the wound was closed in standard fashion. Results: Acute patellar dislocation with osteochondral fracture has been shown to lower both subjective and functional patient outcome measures. A recent study suggests that in large osteochondral fractures after patella dislocation, internal fixation improves mid- and long-term outcomes when compared with debridement alone. Conclusion: The MPFLR with concurrent osteochondral fracture fixation in patients with open physes is a reliable option for improving patellar stability and protecting articular cartilage from further injury.

What do we need to address when we treat neglected Monteggia fracture in children.

Monteggia fracture is a relatively uncommon injury in pediatric patients, accounting for less than 2% of forearm fractures, characterized by a combination of ulna fracture and radial head dislocation. Neglected Monteggia fractures define as those that have not received treatment within 3 weeks. In children, ulna fractures are easily diagnosed while radial head dislocation may be overlooked, necessitating open reduction after neglecting the Monteggia fracture and potentially causing additional trauma to the child. This study aims to review the pathological characteristics of neglected Monteggia fractures based on the length ratio of the ulna and radius, relative positions between the proximal ends of the ulna and radius, the integrality of annular ligament and the pathological change of proximal radioulnar joint. The findings will provide valuable insights and guidance for managing neglected Monteggia fractures.
