Surgical Fixation of Maisonneuve Fractures with a Screw Suture Fixation Device: Results of 10 Cases

Category: Trauma; Ankle; Sports Introduction/Purpose: Maisonneuve fractures consist of a fracture of the fibula in the proximal third with associated syndesmotic injury. Surgical management generally involves restoration of fibula length, reduction of the syndesmosis, and stabilization of the syndesmosis. Flexible fixation devices have gained popularity for syndesmotic fixation over the last several years. Current flexible fixation devices are not reliable for fixation of length unstable patterns of injury, like the Maisonneuve fracture. The purpose of the study was to evaluate the results of a new screw- suture syndesmotic device providing aperture fixation of the syndesmosis for fixation of Maisonneuve fractures. Methods: 10 consecutive patients with Maisonneuve injuries were treated with indirect restoration of fibula length, open reduction of the syndesmosis, and stabilization of the syndesmosis with the screw suture device. Talocrural angle and medial clear space was measured and recorded at time of injury, post operatively and 6 months. Rate of hardware removal was recorded.***2 patients are 2 months short of 6 months. both have healed their proximal fibula fractures so no changes to data are anticipated *** Results: There were 5 males and 5 females. 5 patients slipped on ice, 4 patients fell on uneven walking surfaces, 1 patient was in a motorcycle accident. 2 patients had associated posterior malleolus fractures, 1 was fixed with a posterior plate. 1 patient had a medial malleolus fracture repaired with 2 screws. 9 devices were placed independently. 1 device was inserted through a 4 hole 1/3 tubular plate. Average time to surgery was 12.3 days (range 5-24 days). Talocrural angles averaged 8.92 (4.8-14.5mm) on injury films, 13.8mm (10.6-17mm) post operatively and 13.5mm (10.6-16.6) at 6 months. Medial clear space measurement averaged 5.68mm (2-10mm) on injury films, 2.06mm (1.9-2.3mm) post operatively and 2.1mm (2-2.3mm) at 6 months. No devices required removal during the study period. Conclusion: The screw-suture device provided length stable fixation for treatment of Maisonneuve fracture patterns.

Outcome of Reoperation for Local Recurrence Following En Bloc Resection for Bone Giant Cell Tumor of the Extremity.

En bloc resection is typically performed to treat giant cell tumors of bone (GCTB), particularly when curettage can be challenging owing to extensive bone cortex destruction with soft tissue extension. Few reports have addressed the clinical outcomes after reoperation for local recurrence in patients with GCTB who underwent en bloc resection. In this multicenter retrospective study, we investigated local recurrence, distant metastasis, malignant transformation, mortality, and limb function in patients treated for local recurrence following en bloc resection for GCTB. Among 205 patients who underwent en bloc resection for GCTB of the extremities between 1980 and 2021, we included 29 with local recurrence. En bloc resection was performed for large tumors with soft tissue extension, pathological fractures with joint invasion, complex fractures, and dispensable bones, such as the proximal fibula and distal ulna. Local re-recurrence, distant metastasis, malignant transformation, and mortality rates were 41.4% (12/29), 34.5% (10/29), 6.9% (2/29), and 6.9% (2/29), respectively. The median Musculoskeletal Tumor Society score was 26 (interquartile range, 23–28). The median follow-up period after surgery for local recurrence was 70.1 months (interquartile range, 40.5–123.8 months). Local recurrence following en bloc resection for GCTB could indicate an aggressive GCTB, necessitating careful follow-up.

Superior Bone Microarchitecture in Anatomic Versus Nonanatomic Fibular Drill Tunnels for Reconstruction of the Posterolateral Corner of the Knee.

Background:Several fibula-based reconstruction techniques have been introduced to address ligamentous injuries of the posterolateral corner of the knee. These techniques involve a drill tunnel with auto- or allograft placement through the proximal fibula.Purpose:To determine the skeletal microarchitecture of the proximal fibula and its association with age and to compare the microarchitecture within the regions of different drill tunnel techniques for reconstruction of the posterolateral corner.Study Design:Descriptive laboratory study.Methods:A total of 30 human fibulae were analyzed in this cadaveric imaging study. High-resolution peripheral quantitative computed tomography measurements were performed in a 4.5 cm–long volume of interest at the proximal fibula. Three-dimensional microarchitectural data sets of cortical and trabecular compartments were evaluated using customized scripts. The quadrants representing the entry and exit drill tunnel positions corresponding to anatomic techniques (LaPrade/Arciero) and the Larson technique were analyzed. Linear regression models and group comparisons were applied.Results:Trabecular microarchitecture parameters declined significantly with age in women but not men. Analysis of subregions with respect to height revealed stable cortical and decreasing trabecular values from proximal to distal in both sexes. Along with a structural variability in axial slices, superior values were found for the densitometric and microarchitectural parameters corresponding to the fibular drill tunnels in the anatomic versus Larson technique (mean ± SD; bone volume to tissue volume at the entry position, 0.273 ± 0.079 vs 0.175 ± 0.063; P < .0001; cortical thickness at the entry position, 0.501 ± 0.138 vs 0.353 ± 0.081 mm; P < .0001).Conclusion:Age represented a relevant risk factor for impaired skeletal microarchitecture in the proximal fibula in women but not men. The region of drill tunnels according to anatomic techniques showed superior bone microarchitecture versus that according to the Larson technique.

Campanacci Grade III Giant Cell Tumors of Distal End Radius Treated With Wide Excision and Reconstruction: A Retrospective Case Series.

IntroductionCampanacci Grade III Giant Cell tumors of the distal radius are difficult to manage as they are associated with a high recurrence rate. Wide excision of the distal radius and reconstruction with an ipsilateral proximal fibula or ulnar translocation reduces the recurrence rate significantly and gives acceptable function to the hand and wrist.Methods and materialsThis was a retrospective study of eight patients with Campanacci grade III giant cell tumors of distal radius treated with wide excision of distal radius followed by reconstruction at our institute. Four cases were operated on with ulnar translocation and four cases were operated on with ipsilateral proximal fibula grafting after wide excision of the distal radius. Patients were studied for the Musculoskeletal Tumor Society (MSTS) score and visual analogue scale (VAS) score for pain at one year, recurrence, and complications.ResultsThe mean MSTS score of the total series was 24.75 ± 1.6. The mean VAS score for the total series was 1.62 ± 0.4. Of the eight cases, two cases had a recurrence, one patient had persistent wrist paint, and two patients had wrist subluxation.ConclusionWide excision of the distal radius followed by reconstruction with a proximal fibula or ulnar translocation is a good option to avoid repeated surgeries in patients with Campanacci grade III giant cell tumors of the distal radius and achieve acceptable functional results for the wrist and hand.

Analysis of related factors of long-term complications after vascularized fibular transplantation.

Free fibula flap is the first choice for jaw reconstruction in head and neck oncology, but postoperative complications in donor site are ignored always. The main purpose of this study was to investigate the long-term complications and potential risk factors of donor site after vascularized fibular transplantation, and to explore the precautions of preparing vascularized fibular flap and the measures of preventing donor site complications. Data were retrospectively collected on 31 patients who had undergone immediate mandibular reconstruction with a fibular flap after segmental mandibulectomy from 2013 to 2018 in Shanghai Ninth People's Hospital. Thirty-one patients (24 male, 7 female) were available for the long-term complications in donor site analysis from 25 to 96months after surgery. The data were collected and analyzed, including age at time of operation, early postoperative complications, incidence of dorsiflexion weakness of hallux, donor site missing fibula length, proximal and distal stump fibula length, and subjective evaluation of foot function (AOFAS-hallux, AOFAS-ankle hindfoot, Enneking lower limb function score). In the single-factor analysis in this study, the correlation between related factors and long-term complications was statistically analyzed. For inter-group comparisons of quantitative data, if the normal distribution was satisfied, two independent sample t-tests were used; p < 0.05 was statistical significant. If the normal distribution was not satisfied, Wilcoxon rank-sum test was used, and p < 0.05 was considered statistically significant. For qualitative data, the Fisher exact probability method was compared between group differences, and p < 0.05 was statistically significant. The most commonly encountered complication in our series was dorsiflexion disorder, flexion deformity, numbness of the lateral side of the lower leg, and dorsum of the foot. Ten patients (32.26%) developed hallux flexion deformity after operation, 17 patients (54.84%) had hallux dorsiflexion dysfunction after operation, and 10 patients (32.26%) had numbness of the lateral side of the lower leg and dorsum of the foot. The incidence of hallux dorsiflexion dysfunction, thumb flexion deformity, and sensory disturbance was higher than that of other long-term complications in the donor area. The residual length of fibular distal was related to the dorsiflexion dysfunction and flexion deformity of hallux (p < 0.05). The early complications of donor site were correlated with the hallux dorsiflexion dysfunction (p < 0.05). The incidence of dorsiflexion disorder and flexion deformity is higher in patients after fibula transplantation. The less the residual length of fibular distal, the more obvious the long-term complications in the donor site, and the higher the incidence of dorsiflexion dysfunction and flexion deformity of hallux. The long-term complications of donor site after fibular transplantation seriously affect the quality of life of patients and provide clinical reference for further reducing the occurrence of donor site complications.

Characterization of primary fibular bone tumors and post-surgical clinical and functional outcomes.

Objectives In this study, we present the characterization of tumors located in the fibula, which is a rare site for tumors, and the clinical and functional results of patients with fibular tumors that we operated in our clinic.Patients and methods Between February 2008 and December 2018, a total of 104 patients (58 males, 46 females; mean age: 26±18 years; range, 3 to 78 years) who were operated for tumor located in the fibula were retrospectively analyzed. Demographic data, histopathological diagnosis, tumor localization, surgical method and postoperative complications, metastases, follow-up time, and functional results of the patients were recorded. The fibula was divided into three groups as proximal, diaphysis and distal one-third.Results The mean follow-up was 56±25.3 (range, 24 to 108) months. Eighty (76.9%), seven (6.7%) and 17 (16.3%) patients were located proximal, diaphysis and distal to the fibula, respectively. The number of patients with malignant tumors located in the fibula was 26 (25%), the tumor was benign in 54 (51.9%) patients and 24 (23%) tumors were borderline. The most common tumor localized to the fibula was osteochondroma with 28 (26.9%) patients. The most common malignant tumors located in the fibula were Ewing sarcoma and osteosarcoma in 11 patients each. The most common surgical method was curettage in 44 (42.3%) patients. Distant organ metastases were present in 18 (17.3%) patients. The Musculoskeleteal Tumor Society score of 17 patients who underwent resection of the proximal fibula were 87%.Conclusion Fibula is a rare location for tumors and fibula tumors tend to be located more proximal. Tumors located in the fibula have good functional outcomes after surgery.

Gait Improvement in Patients with Knee Osteoarthritis after Proximal Fibular Osteotomy.

Proximal fibula osteotomy (PFO) is a relatively new surgery to treat medial compartment knee osteoarthritis (KOA), which can improve varum deformity and relieve knee joint pain. However, the gait alterations in KOA patients after PFO are still poorly understood. The purpose of this study was to evaluate the gait patterns change in patients of medial compartment KOA after PFO. Gait data were collected for 9 females with unilateral medial compartment KOA before and at 6 months after PFO and also for 9 healthy age-matched females. Paired t-test was used to determine the effect of PFO within the KOA group, and independent t-test were performed to compare between KOA and control groups for spatiotemporal, kinematic, and kinetic variables. The results showed that patients with KOA had significantly increased knee peak flexion angle, knee sagittal range of motion, and peak external hip adduction moment but decreased knee frontal range of motion in the affected limb after PFO. The gait symmetry was improved postoperatively confirmed by single support and swing phases, knee peak flexion angle and sagittal range of motion, peak external hip and knee adduction moments, and peak anterior and peak posterior ground reaction forces. These findings provided evidence of a biomechanical benefit and gait improvement following PFO to treat medial compartment KOA.

Management of Bosworth Fracture: Case Report

Introduction: Bosworth fracture is an uncommon fracture that involves the distal fibula associated with a dislocation of the proximal fibula fragment being posterior to the tubercle of the tibia distally. As the proximal fibula fragment becomes entrapped behind the Tibia it subsequently makes it irreducible which then necessitates the correction of this fracture surgically. Making an initial diagnosis of this fracture is quite difficult as it is rare and few data in our setting have been recorded with only a handful of documented cases worldwide. Although attempts have been made to reduce this fracture with closed reduction, the outcomes are generally unfavourable and counterproductive. Bosworth fracture is well documented in medical literature but often not easily picked at presentation.&#x0D; Case Presentation: This case report evaluates a 19 year old female student who presented with a 2 hours history of pain and deformity to her right ankle after she had accidentally externally rotated her ankle with the foot in a prone position while running down the stairs. Examination revealed a deformed and swollen right ankle joint, overlying skin was intact, tender limitation of joint movement. She had a failed closed reduction and was subsequently counselled for open reduction and internal fixation with plates and screws.

Changes in the Tibial Strain After Proximal Fibular Osteotomy: A Biomechanical Cadaveric Study.

Total knee arthroplasty surgery is an increasingly common procedure for the treatment of uni- and tricompartmental knee osteoarthritis, particularly in advanced stages and in the older population. Its usage is being extended to younger patients, where implant longevity is of concern. In the younger age group, especially with early disease, other options merit consideration. On the other hand, it may not be possible for elderly patients with medical comorbidities to undergo joint replacement surgery. Proximal fibular osteotomy (PFO) has recently been advocated to treat medial knee osteoarthritis. Although there have been clinical reports showing promising outcomes, the biomechanical basis of this procedure is still unclear. We performed a cadaveric study to investigate the effect of PFO on proximal tibial strain. Eight unpaired cadaveric lower limb specimens were loaded in compression at 2 times body weight. Strain gauges were mounted on various sites on the proximal tibia and fibula. After PFO, there was a significant increase in the lateral tibial strain adjacent to the proximal tibiofibular joint (P<.05). There was moderate effect size reduction in the anteromedial tibial strain as well as moderate effect size increase in the posterior tibial strain. The strain reduction seen at the anteromedial tibia can offer a possible explanation for symptomatic relief after PFO. However, the increase in the lateral and posterior tibial strain raises concern about long-term accelerated wear in these regions. [Orthopedics. 2022;45(5):314-319.].

Autologous replacement of the head of the radius—proximal fibula versus second metatarsal base: an anatomic feasibility study

IntroductionThis study investigated the anatomic feasibility of a new surgical therapy option for radial head arthrosis using an autologous vascularized bone graft of the second metatarsal and proximal fibula to recreate the proximal radiohumeral joint.Materials and methodsUpper and lower extremities of eleven body donors were evaluated using CT prior to anatomic dissection. Several distinct anatomic parameters were measured on the ipsi- and contralateral radial and fibular head and the second metatarsal base: bone diameter, articular surface diameter, head height, metaphyseal (neck) diameter, articular surface radius, total articular surface area, and angulation of the articular surfaces (facet). Each dissection phase was photographed in a standardized fashion and all measurements were repeated by direct caliper-measurements.ResultsWhen comparing the proximal radius and fibula to search for anatomic similarities, similar values were found in the maximum articular surface diameter and minimum and maximum measures of the neck diameter. Comparing the proximal radius and the second metatarsal, statistically similar values were found in the maximum neck diameter performing direct measurements and CT evaluation, the maximum head diameter in CT evaluation and the articular facet angulation.ConclusionsNeither the proximal fibula nor the base of the second metatarsal are ideal bone grafts for replacement of the head of the radius. The base of the second metatarsal might be a bit more suitable as a potential donor since the angulation of the proximal articular facet is similar to that of the radius.Level of evidenceLevel IV, anatomic study.

P152 A rare case of necrotising vasculitis presenting with calf swelling in a 15-year-old female

Abstract Background/Aims We present the case of MF, a 15-year-old female who presented to the paediatric clinic with swelling and pain affecting her right calf. She was previously fit and well. Initial imaging was suggestive of localised myositis but a subsequent muscle biopsy was in keeping with necrotising vasculitis. Methods In May 2021, MF presented to a general paediatric clinic with a 6-week history of right lateral calf pain and swelling to the lateral border of the right proximal fibula. She was systemically well. Blood tests and an x-ray were normal. An ultrasound scan of the right calf showed fusiform thickening of the peroneus longus muscle proximally. There was no discrete mass. The appearance was thought to be an inflammatory process such as myositis. An MRI scan was advised. Over the course of the next few weeks, the swelling and pain to the right calf progressed and she was unable to fully weight bear. Repeat blood tests were normal except CRP 11. CK was normal. At the end of June, an MRI scan of the right lower leg showed significant swelling and oedema along the length of the peroneus longus musculature as demonstrated on ultrasound. Florid oedema extended to involve the soleus and to a lesser extent the lateral head of gastrocnemius. There was thickening and oedema through the subcutaneous fat circumferentially compared to the left side (see images). The appearances were thought to be consistent with myositis but an inflammatory malignancy could not be fully excluded and an opinion from the Birmingham team was recommended. The Birmingham MDT advised that malignancy was unlikely but a CT scan was recommended. The CT scan confirmed the MRI findings (see image). Results MF's symptoms progressed rapidly over a short period of time with diffuse swelling of the right lower limb with associated pain and numbness. She also developed purpuric lesions around the ankle (see photos). The CRP increased to 59 and then 123. CK remained normal. Local rheumatology opinion was sought once malignancy had been excluded. The initial impression was of a focal myositis but a muscle biopsy was requested urgently. IV steroids were administered followed by high dose oral prednisolone as a reducing course. The symptoms improved rapidly. The subsequent biopsy showed a florid necrotising vasculitis affecting the small-medium arterial vessels. There was no evidence of myositis (see image). ANCA was negative and CT renal and abdominal angiogram was normal. Nerve conduction studies showed a very severe sensory lesion of the right sural nerve, which explained the persistent numbness. Mycophenolate mofetil was added and clinical improvement is ongoing. Conclusion We present a rare case of localised vasculitis in the right calf. A literature review indicates this is the first case presented in an adolescent. Disclosure S.C. Earl: None. J. Smith: None. A. Ramanan: Grants/research support; Abbvie.

Neuromonitoring for Proximal Fibular Osteochondroma Excision.

The peroneal nerve is at risk when excising tumors in the proximal fibula. The rate of nerve injuries during proximal fibular tumor resection varies from 3% to 20%. Our goal was to report our experience with resection of osteochondromas in the proximal fibula and describe the technique and utility of neuromonitoring during excision of proximal fibular osteochondromas (PFO). Patients with a diagnosis of symptomatic PFO who had undergone excision at one institution from 1994 to 2018 were included. An institutional review board-approved retrospective review was performed. Intraoperative neuromonitoring was provided from 2006 on by a single group utilizing a multimodality protocol. This study contains 29 patients who had excision of osteochondromas in the proximal fibula. Of these 29 consecutively monitored patients, there were 34 involved extremities. Intraoperative neuromonitoring alerts occurred in 10/29 (34.5%) procedures, which included 3 electromyography (EMG) (30%), 2 motor-evoked potential (20%), 1 somatosensory-evoked potential (10%), and 4 alerts with a combination of EMG/motor-evoked potential/somatosensory-evoked potential changes (40%). The interventions that were taken resulted in resolution of the neuromonitoring changes in all procedures. Postoperatively, we noted 2 (6.9%) new mild sensory deficits, which resolved during follow up. There were 3 patients in whom pre-existing sensory-motor deficits improved but not completely after surgery, 1 motor weakness, and 2 with residual paresthesia. In those initially presenting with paresis, there was improvement in 8 of the 8 extremities by the last follow-up visit. Pain as a symptom was resolved in all cases. There were no iatrogenic foot drop injuries. The average follow up was 32.2 months. Neuromonitoring during PFO excision demonstrated a high number of alerts, all of which resolved following timely corrective action. The use of neuromonitoring may help decrease the risk of iatrogenic postoperative neurological deficits following fibular osteochondroma surgery. Level IV.

A Quality Analysis of Bony Specimens for Optimal Ethylenediaminetetraacetic Acid (EDTA) Decalcification.

Introduction: Weak acids, such as etheylenediaminetetraacetic acid (EDTA), chelate calcium ions from the surface of tissues, decalcifying slowly but preserving molecular structures for ancillary testing. There is a need for optimization of EDTA protocols for specimen decalcification. We studied the effects of EDTA on different types of bony specimens for quality assurance. Methods: Specimens included: proximal femur curettage (0.7 g), fibula shave (1 mm thick, 0.5 g), tibia shave (2 mm thick, 0.9 g), and femur 11-gauge core biopsies. Curettage and shave specimens were placed in formalin then EDTA (Newcomersupply, Middleton, WI, USA) with continuous stirring. Specimens were removed at 24, 48, 72, 96, and 120 hours. Core biopsies were processed in EDTA with heat at 4, 8, 12, and 16 hours. X-ray imaging (Kubtec Xpert 40, Stratford, CT, USA) was obtained. Histological processing was attempted and H&E slides compared to radiologic imaging. Results: Fibula and tibia sections showed appropriate radiolucency at 120 hours and 7 days, respectively. Curettage specimens showed radiolucency of medullary bone at 48 hours. Curettage and fibula sections showed quality histology at 96 hours and 120 hours, respectively. Quality tibia sections were obtained at 7 days, requiring one hour of additional block surface decalcification with 1% HCL solution. Medullary and cortical core biopsies showed quality histology at 12 and 16 hours with heat, respectively. Conclusion: Imaging can determine appropriate decalcification of bony specimens. Medullary bone undergoes more rapid decalcification in EDTA than cortical bone. EDTA decalcification is best used for curettage and core biopsy specimens.

Lateral Collateral Ligament and Biceps Femoris Tendon Fixation with a Suture Anchor to the Tibial Metaphysis after Proximal Fibula En Bloc Resections Preserve Lateral Knee Stability.

This study aims to analyze the functional outcomes and lateral knee stability of patients who underwent lateral collateral ligament (LCL) and biceps femoris tendon reconstruction with suture anchors after proximal fibula en bloc resection for bone tumors. Patients who underwent proximal fibular en bloc resection between 2007 and 2018 were retrospectively viewed. Patients were invited to visit the clinic, and their functional scores were evaluated using the Musculoskeletal Tumor Society Scoring (MSTS) system. Lateral knee stability was evaluated by varus stress radiographs obtained at 20 degrees of flexion, and the range of motion (ROM) of the bilateral knee was assessed. Side-to-side differences were graded according to the International Knee Documentation Committee (IKDC) criteria and compared between types I and II resections. A total of 17 patients (4 males and 13 females) with a mean age of 31.1 ± 17.1 (range: 13-65) years at the time of surgery were available for radiological and clinical examination at a mean follow-up of 68.6 ± 36.4 (range: 22-124) months after surgery. In terms of ROM measurements, IKDC grades and side-to-side differences in both flexion and extension were not significantly different between the groups. On varus stress radiographs, lateral knee gapping was measured to be 0.93 ± 0.91 mm in type-I resections and 1.83 ± 0.45 mm in type-II resections, and statistically significant differences were detected among the groups (p = 0.039). When the values were graded according to IKDC criteria, none of the knees were classified as abnormal, and no difference was observed between the groups. Mean MSTS score of patients with type-I resections was significantly higher than those of patients with type-II resections (92.7 vs. 84.4%, p = 0.021). In the subscale analysis, a significant difference was observed in the support scores (type I = 94.5%, type II = 70%; p = 0.001). The reattachment of LCL and biceps femoris tendon to the tibial metaphysis with a suture anchor is a simple and effective method to prevent lateral knee instability after proximal fibula resections.

Knee Joint Radiographic Examination Technique with Anteroposterior and Lateral Projections in Osteoarthritis Cases

Radiographic examination of the knee joint in Osteoarthritis (OA) cases was generally performed using anteroposterior (AP), lateral and oblique projections. However, at the Regional General Hospital (RSUD) of Ajibarang, in the case of OA the knee joint only used AP and lateral projections. The purpose of this study was to determine the radiographic examination procedure and ensure the criteria for the image generated from the AP projection and lateral examination of the knee joint in OA cases. This research was a qualitative descriptive with a case study approach. Collecting data on 1 knee joint patient with OA in Ajibarang Hospital using observation, documentation and interviews with radiographers and radiologist. Data analysis used open coding in the form of quotations. The results showed that the AP and lateral projections were performed with the central ray perpendicular to the cassette and showed the distal femur, tibia, proximal fibula and patella, the femoropatellar joint and the knee joint were exposed and the true lateral was shown by superposition of the femoral condyles. Finally, examination of the knee joint of OA cases at Ajibarang Hospital with AP and lateral projections can still display the anatomy of interest and determine the diagnosis of OA cases.

Open lower extremity fractures in the geriatric population.

Open fractures in the elderly are distinct compared to younger populations. The purpose of this study is to follow a series of open fractures of the lower extremity in the geriatric population to better prognosticate outcomes. We performed a retrospective chart review of patients over the age of 65years old who were treated for an open, lower extremity fracture across two level I trauma medical systems. Patients were included if they had documented wound healing problems in the postoperative period, or 6months of follow-up, or if they had a definitive radiographic outcome. Sixty-four patients were included of an average age of 76.23, of whom 73.4% were female. The fracture types were midshaft femur in 3, distal femur in 9, patella in 2, proximal tibia in 3, proximal fibula in 1, midshaft tibia in 14, distil tibia in 8, ankle in 23, and talar neck/calcaneus in 1. Forty-two fractures were the result of low energy mechanism and 22 fractures were from high energy mechanism. Fourteen fractures were type 1, 32 were type 2, 11 were type 3A, 6 were type 3B, and 1 was type 3C. At final follow-up, 13 wounds were well healed, 39 wounds were healed following a delay of more than 6weeks to achieve healing, 3 were infected, 3 had been treated with amputation, 2 had chronic ulceration, 2 with active draining, and 2 had draining sinuses. Open lower extremity fractures are serious injuries with high rates of morbidity. Such risks are even higher in the geriatric population, particularly with regard to wound healing. This study provides important prognostic information in counseling geriatric patient with an open lower extremity fracture, as well as informs treatment in terms of wound surveillance and care in the postoperative period.

Use of portable ultrasonography for the diagnosis of lateral ankle instability.

Portable ultrasonography is increasingly used to evaluate ankle stability at the point of care. This study aims to determine the correlation of portable-ultrasonographic and fluoroscopic measurements of ankle laxity in a cadaveric ligament transection model of ankle ligament injury. We hypothesize that there is an association between portable-ultrasonographic and fluoroscopic measurements when performing stress evaluation of lateral ankle instability. Eight fresh-frozen below-knee amputated cadaveric specimens with intact proximal fibula underwent ultrasound and fluoroscopic evaluation of the ankle during anterior drawer and talar tilt testing. The assessment was first performed with all lateral ankle ligaments intact and thereafter with sequential transection of the anterior talofibular ligament, calcaneofibular ligament, and posterior talofibular ligament. The anterior drawer test was performed with both 50N and 80N of force, and talar tilt test was performed with 1.7 Nm of torque. Correlations between (1) portable-ultrasonographic and fluoroscopic measurements and (2) sequential transection of lateral ankle ligaments were evaluated using Spearman's rank correlations. The same statistical test was used to investigate the correlation between the ultrasonographic and the fluoroscopic measurements. The inter- and intra-observer agreement was assessed using the intraclass correlation coefficient through a two-way mixed-effects model with absolute agreement. Portable-ultrasonographic and fluoroscopic measurements increased as additional ligaments of the lateral ankle were transected (Spearman's rank correlation ranged from 0.74 to 0.81, 0.74 to 0.81, p-values < 0.001). Strong positive correlations between ultrasonographic and fluoroscopic measurements were found during the lateral ankle stability evaluation using anterior drawer and talar tilt testing (Spearman's rank correlation ranged from 0.81 to 0.85, 0.81 to 0.85, p-values < 0.001). Inter-rater (0.99, 95% CI: 0.98-0.99) and intra-rater reliability (0.97, 95% CI: 0.95-0.99) for the ultrasonographic measurements were substantial. In conclusion, there was a strong correlation found between ultrasonographic and fluoroscopic values measured during simulated anterior drawer and talar tilt test in a cadaveric ligament transection model. In this model, the portable-ultrasonographic measurement was found to be reliable for repeated measurements of the talar translation and the lateral clear space distance. Based on these data, ultrasonography is likely to become a valuable point of care diagnostic tool due to its ability to readily and dynamically evaluate suspected lateral ankle instability. Clinical Significance: The use of dynamic stress ultrasound to assess the anterior translation of the talus and the lateral clear space distance appears to be a reliable and repeatable technique to evaluate lateral ankle stability with a radiation-free, noninvasive, and low-cost manner.

Utilizing Multiple Pedicled Muscle Flaps in Complex Soft Tissue Reconstruction - A Case Report

Utilizing multiple muscle flaps is a safe and reliable technique to provide stable soft tissue cover for major post-traumatic defects of the lower limbs. A fifty-five-year-old female patient presented to the emergency department with a huge crush/degloving injury of the whole anteromedial aspect of the right lower limb with open comminuted fracture of the femur, the tibia, and the fibula. Radiological computerized tomography (CT) study showed displaced comminuted fractures involving the lower shaft of the femur, proximal fibula, and middle third of the shaft of the tibia, with tangential bone loss in the knee joint. The patient underwent multiple sessions of wound and bone debridement with bone fixation which was followed by multiple reconstructive surgeries. Patient recovered well and was discharged home with the ability to mobilize with Zimmer frame and knee brace support.

Giant Cell Tumor of Distal Ulna – A Rare Case Report

Among the benign primary bone tumors, Giant cell tumor (GCT) accounts for about 3% to -5%. It is a locally aggressive tumor with maximum incidence between 20 to and 40 years of age. The sites where GCT is most commonly seen are distal femur, and proximal tibia followed by distal end radius. Distal end of ulna is a rare site with an incidence of only 0.45% to -3.2%. We report a case of a 32- year- old male with (GCT) giant cell tumor of the left distal ulna. We managed the patient with en bloc resection of distal ulna along with reconstruction of distal radio ulnar joint (DRUJ) and triangular fibro cartilage complex (TFCC) using proximal fibula graft and palmaris longus graft. DRUJ was stabiliszed with a k- wire. After 1 year of follow- up, patient showed good results in terms of range of movements of the wrist joint with no evidence of recurrence.
