Vertebral body recollapse without trauma after kyphoplasty with calcium phosphate cement

Traditionally, immobilization and external bracing has been recommended for patients with type A traumatic and non-osteoporotic fractures that do not present neurological deficits or significant instability. Nevertheless, several authors have recently suggested the possibility to treat thoraco-lumbar and lumbar vertebral compression post-traumatic fractures using standalone balloon kyphoplasty with osteoconductive filler materials, such as calcium phosphate (CPC). Maestretti and Huang have demonstrated the advantages of this technique showing an almost immediate return to daily activities without the inconvenience of wearing a brace, pain reduction, minimal operative risks and maintenance of stability, therefore proposing this as a first-choice technique in young patient needing rapid spine stability. The authors present a case of vertebral body recollapse after kyphoplasty with calcium phosphate cement (CPC) in a 47-year-old man with an A1.2 post-traumatic L1 compression fracture.

Interprosthetic femoral fractures-A challenge of treatment. A systematic review of the literature.

The success of prosthetic surgery has led to an increase in the percentage of the population having more than one prosthetic implant. This, combined with an increase in the average life expectancy and functional requirements for the elderly, has led to a higher incidence of periprosthetic and interprosthetic fractures. More precisely, the femoral shaft is compressed between two ipsilateral implants with most of these fractures being located on the supracondylar femoral shaft. Their treatment is not only technically demanding and challenging, but can also be associated with serious complications. Treatment must be determined and assessed according to the type of fracture, the stability of the prosthesis, the bone quality and the general condition of the patient. There is little information in the literature about this type of injury: there are several published case reports detailing unconventional solutions and the case studies presented are limited and not significant. This review aims to provide an updated and comprehensive list of diagnostic and therapeutic protocols accepted today, while recognising that these protocols are being continuously updated according to experience gained.

Conservative treatment of fractures of the clavicle

BackgroundIn the treatment of clavicle fractures, the choice of procedure depends on the possibility of restoring the anatomical functional integrity of the shoulder.MethodsWe examined 71 patients (51 males and 20 females, mean age 38.9 years) who were affected by clavicle fracture sequelae. Demographic and clinical data and the site of the lesion were recorded for each partecipant. The dissatisfaction of the patient was determined by the presence of 1 or more affirmative answers on the Simple Shoulder Test. The Constant Shoulder Score was also included in the functional and clinical exams. We measured the length of the healthy clavicle and the previously fractured clavicle, and we expressed the difference in length in mm and in percentage shortening. We then examined the correlations between the shortening of the bone and the clinical and functional outcomes of the patients.ResultsSixty patients had a lesion of the diaphysis, 8 patients had a lesion of the lateral third of the clavicle, and 3 patients had a lesion of the medial third of the clavicle. The mean Constant Shoulder Score was 77.9, and 51 of the 71 patients were satisfied with their treatment. Radiography showed a mean clavicle shortening of 10 mm (mean percentage 6.5%). In the 20 dissatisfied patients, the mean clavicle shortening was 15.2 mm (9.7%). In these patients, we found a highly significant association between dissatisfaction with treatment and the amount of bone shortening, (p < 0.0001), as well as with a diaphyseal location (p < 0.05) and with the female sex (p = 0.004). No other variable related to the patient, the type of treatment or the fracture characteristics correlated with the treatment outcome.ConclusionsIn the literature, measurements of the shortening of the bone segment following a fracture range between 15 and 23 mm, and marked shortening is correlated with the failure of conservative treatment. However, these data need to be reinterpreted in light of the physiological variability of the clavicle length, which ranges from 140 to 158 mm in the healthy population. Shortening of the bone by more than 9.7% should be the cut-off for predicting failure of conservative treatment.

Alumina-on-alumina total hip replacement for femoral neck fracture in healthy patients

BackgroundTotal hip replacement is considered the best option for treatment of displaced intracapsular fractures of the femoral neck (FFN). The size of the femoral head is an important factor that influences the outcome of a total hip arthroplasty (THA): implants with a 28 mm femoral head are more prone to dislocate than implants with a 32 mm head. Obviously, a large head coupled to a polyethylene inlay can lead to more wear, osteolysis and failure of the implant. Ceramic induces less friction and minimal wear even with larger heads.MethodsA total of 35 THAs were performed for displaced intracapsular FFN, using a 32 mm alumina-alumina coupling.ResultsAt a mean follow-up of 80 months, 33 have been clinically and radiologically reviewed. None of the implants needed revision for any reason, none of the cups were considered to have failed, no dislocations nor breakage of the ceramic components were recorded. One anatomic cementless stem was radiologically loose.ConclusionsOn the basis of our experience, we suggest that ceramic-on-ceramic coupling offers minimal friction and wear even with large heads.

Vertebral Bone Marrow Edema (vbme) in Conservatively Treated Acute Vertebral Compression Fractures (vcfs): Evolution and Clinical Correlations

Study Design. Prospective observational study. Objective. To assess (1) the evolution of vertebral bone marrow edema (VBME) in patients with A1 vertebral compression fractures (VCFs) conservatively treated and (2) the relationship between VBME and clinical symptoms, evaluated as Visual Analogue Scale (VAS) back pain and Oswestry Disability Index (ODI). Summary of Background Data. VBME is a marker of acute–subacute vertebral fractures. Little is known about the evolution of VBME in conservatively managed VCFs, as well as its clinical meaning. Methods. 82 thoracic or lumbar VCFs (21 post-traumatic; 61 osteoporotic VCFs), type A1 according to the AOSpine thoracolumbar spine injury classification system, in 80 patients were treated with C35 hyperextension brace for 3 months, bed rest for the first 25 days. Patients with osteoporotic fractures also received antiresorptive therapy and vitamin D supplementation. At 0 (T0), 30 (T1), 60 (T2), and 90 (T3) days, patients underwent magnetic resonance imaging evaluation and clinical evaluation, using VAS for pain and ODI. The paired t test was used to compare changes within groups at each follow-up versus baseline. The unpaired t test after ANOVA (analysis of variance) was used to compare the 2 groups at each follow-up. The association between VBME area, VAS score, and ODI score was analyzed by the Pearson correlation test. The tests were 2-tailed with a confidence level of 5%. Results. A significant VBME mean area, VAS, and ODI scores reduction was recorded at 60 and 90-days follow-ups versus baseline. A positive correlation between VBME reduction and clinical symptoms improvement (VAS and ODI scores improvement) was found in both traumatic and osteoporotic VCFs. Conclusion. In benign A1 VCFs conservatively managed, VBME slowly decreases in the first 3 months of magnetic resonance imaging follow-up. This VBME reduction is related to clinical symptoms improvement.

On a case of multifocal osteonecrosis in a patient suffering from acute lymphoblastic leukemia

The Authors describe the case of a 14-year-old girl who developed a multifocal osteonecrosis (ON), after treatment with chemotherapy and corticosteroids for acute lymphoblastic leukemia (ALL). She came to our attention about 6 months after the beginning of treatment complaining of pain in her left knee and later in both hips and shoulders. Radiography and MRI confirmed the presence of avascular ON at all these sites. The patient underwent bilateral total hip arthroplasty, which was still functioning well at the last follow-up visits at 5 years, and at 5 years and 4 months. ON is increasingly recognized as a complication of the treatment of cancer in children and adolescents, and as patients now frequently survive ALL into adulthood, orthopedists will be increasingly called on to manage this complication affecting multiple joints in children and young adults.

Arthroerisis with Giannini’s endo-orthotic implant and Pisani’s talocalcaneal arthroerisis. A comparison of surgical methods

In this paper the Authors report the results gained after the treatment of paediatric idiopathic flat foot by means of Pisani’s talocalcaneal arthroerisis and arthroerisis with Giannini’s endo-orthotic implant. Two groups of patients have been treated according to the two techniques. According to clinical, radiographic and functional tests, the Authors believe that both the techniques can offer good results to correct idiopathic flat foot of childhood and they highlight the lower invasivity and less damage for the structures of sinus tarsi when Pisani’s talocalcaneal arthroerisis is applied.

Hip joint hydatidosis after prosthesis replacement

Hydatidosis is a rare parasitic disease caused by the Echinococcus tapeworm, which only occasionally affects the musculoskeletal tissues. In this article we describe the case of a patient who underwent a total hip replacement procedure for a pathological fracture of the femur neck. At the next histological examination it was shown to be a consequence of secondary bone hydatidosis. This clinical case is exceptional in that the infection spread to the cotyloid and femoral prosthesis components and, in the following years, caused repeated episodes of joint dislocation.

Is distal locking with short intramedullary nails necessary in stable pertrochanteric fractures? A prospective, multicentre, randomised study

We investigated whether a proximal femoral nail can be implanted without a distal locking screw in AO/OTA 31-A1 and 31-A2 pertrochanteric stable femur fractures. A multicentre, randomised study was conducted in six level-two trauma centres in our area (Puglia, Italy). A total of 333 patients received their allocated intervention (162 in the locking group [LG] and 171 in the unlocking group [UG]) and 266 patients were included in the final analysis at 1year. Our data showed no statistically significant difference between the two groups at 1-year follow-up for ability to walk, SF-36 questionnaire results, residual pain (visual analogue scale [VAS] score) and level of overall satisfaction. There were also no statistically significant differences between groups for mortality and length of hospital stay. Conversely, the UG was associated with shorter operation and fluoroscopy times, shorter surgical incision length, and less blood loss and residual thigh pain. Pertrochanteric stable fractures (31-A1, 31-A2) can be treated successfully with intramedullary nails without distal locking, reducing patient and clinical personnel radiation exposure and sanitary costs (surgery time and screws costs).

Volar locking plate vs epibloc system for distal radius fractures in the elderly

PURPOSE To compare clinical outcomes of ORIF with volar locking plates and the Epibloc system (ES) in the treatment of distal radius fractures (DRFs) in patients aged over 65 years. METHODS We retrospectively examined a consecutive series of 100 patients with intra-articular or extra-articular DRF who were admitted to our Department of Orthopaedics and Traumatology between January 2007 and January 2013. Fifty patients were treated using the Epibloc System; and the other 50 patients using ORIF with volar locking plates. In all patients, functional evaluation (wrist range of motion [ROM], grip strength and Disability of the Arm, Shoulder and Hand [DASH] Score) and radiographic assessment (radial inclination, volar tilt, ulnar variance and articular congruity) were performed at 2 and 6 weeks, and 3, 6 and 12 months postoperatively; then every 12 months thereafter. RESULTS ORIF with volar locking plates was associated with better outcome than ES in the intra-articular and extra-articular DRF groups, generating higher average ROM, DASH and visual analogue scale (VAS) scores. Grip strength mean values, however, were quantified over the minimum level for a functional wrist (>60%) in both groups. There were no differences between the two techniques in X-ray parameters, and no further correlation was found with functional outcome and ROM. CONCLUSIONS In a low-functioning patient with multiple medical comorbidities, minimally-invasive surgery with the ES is a safe option, enables early mobilisation of the wrist and is likely to produce acceptable clinical outcomes.
