Popliteomeniscal fascicles tears with lateral meniscus instability: outcomes of arthroscopic surgical technique at mid-term follow-up.

PURPOSE: The popliteomeniscal fascicles (PMFs) are a crucial part of the posterolateral corner of the knee. They provide stability to the lateral meniscus and stabilize the joint during tibial internal rotation. The clinical diagnosis of a torn PMFs is difficult, and magnetic resonance imaging (MRI) may be inconclusive as well. The aim of the present study was to report the outcomes of a continuous series of patients affected by PMF lesions and treated with an arthroscopic repair. METHODS: Seventeen patients (average age of 22 ± 3.6 years) with PMF lesions and lateral meniscus instability were prospectively enrolled. All patients were evaluated with clinical examination, International Knee Documentation Committee (IKDC), Lysholm and Tegner scores and 1.5 T MRI. All patients had the same arthroscopic procedure consisting of meniscal repair with an all-inside meniscal repair system (mean 2.2 ± 0.77 anchors) and followed with the same postoperative protocol. RESULTS: All patients were available at a mean follow-up of 68 ± 24 months (range 49-84 months). Mean IKDC increased from 60.2 ± 13.5 to 83.1 ± 12, mean Lysholm score improved from 56.7 ± 8.2 to 89.8 ± 3.2, and mean Tegner score improved from 2.9 ± 1.3 to 6.5 ± 2. No intraoperative or postoperative complications were reported. MRI evaluation at 6-month follow-up showed successful healing of the menisco-popliteal fascicles in all cases. CONCLUSIONS: The diagnosis and treatment of tears of the PMFs is still debated. Diagnostic confirmation of tearing of the PMFs is usually determined at the time of arthroscopy. Meniscal repair with an all-inside meniscal repair system appears to be an excellent treatment option, since it yields good functional results at mid-term follow-up, no local complications, and complete radiographic healing at 6-month follow-up MRI. Further studies are needed to confirm these promising early results. LEVEL OF EVIDENCE: Case series, 4.

DOES AN EARLY POST-OPERATIVE PAIN RELIEVE INFLUENCE THE FUNCTIONAL OUTCOME OF PATIENTS WITH COLLES FRACTURES TREATED WITH EG-BLOCK SYSTEM?

Distal Radius Fractures (DRFs) represent one of the most common elderly patient's fractures. Often DRFs required surgical treatment based on instability of the fragments and due to the high functional demand from patients. A general agreement on the best pharmacological treatment in the post-operative is still missing. The present study describes the clinical outcome in patients who underwent surgery for Colles fracture using ES fixation osteosynthesis. ; The present investigation represents a one center retrospective analysis. In this study, two different medical treatments were recognized, and groups consequently set (Group A: Ketoprofene 100 mg twice a day for 5 days, 59 patients; Group B: Tramadol 75 mg and Dexketoprofen 25 mg, 62 patients). Outcomes were the functionality of the affected wrist through AROM assessment and the evaluation of painkillers intake, pain itself and Quick-DASH.; 121 patients were included in the present study. The pharma blending of Tramadol 75 mg and Dexketoprofen 25 mg resulted effective for the rapid recovery of the treated wrist motion. In fact, in the group B motion was better compared to group A (p<0.05) for any movement examined (flexion, extension, pronation, supination) until the last follow-up (70 days).; Associations of different painkillers are common, even if a general agreement on the most effective combination is still missing. Tramadol and Dexketoprofen provide a good clinical result, less side effects and a better functional recovery of the wrist motion. This guarantees a fewer social cost and a best management of post-operative physiotherapy.

Conservative management of Anderson Type II odontoid fractures in octogenarians: is radiological union what we are searching for?

OBJECTIVE: The C2 odontoid fractures represent one of the most common cervical spine injuries. Stabilization and immobility are required for a correct treatment. However, in some cases surgical treatment is recommended. There are still no guidelines for Type II odontoid fractures management. The present study aims at determining how non-union could impact on mortality, functional and clinical outcomes in octogenarian patients conservatively treated. MATERIALS AND METHODS: The present investigation is a retrospective case series. All patients with diagnosis of Type II odontoid fractures, over 80 years and conservatively treated in our institution between January 2016 to April 2020 were potentially eligible for the study. The primary outcome was the bony fusion of the fracture after 3 months of conservative treatment. The secondary outcomes were clinical, functional outcomes and mortality. RESULTS: Sixty-four patients were eligible for the study according to inclusion and exclusion criteria. Computer Tomography (CT) evaluation performed 3 months after trauma showed complete fracture healing in 31 patients (48.4%, Fused), while 33 patients (51.6%) were evaluated as non-fused. Among these, 6 months after the CT evaluation, 14 patients were classified as stable, while 19 were classified as unstable. There were no statistically significant changes in clinical and functional outcomes reported in our patient series between patients with complete radiological healing and patients who reported stable fibrous non-union. CONCLUSIONS: In a selected group of elderly patients with a high risk for surgery, the conservative treatment of odontoid Type II fractures can be considered a viable management strategy. The achievement of a stable non-union allows for clinical and functional results comparable to complete fracture healing.

Could serum procalcitonin play a role in an emergency setting for patients with pyogenic spondylodiscitis?

OBJECTIVE: Spinal infections, represent quite rare but often severe conditions. However, due to symptoms' non-specificity and the lack of specific laboratory tests, diagnosis is often delayed with serious consequences for the patient's outcomes. The present investigation aimed at evaluating the role of procalcitonin (PCT) and other clinical features on the risk stratification and the clinical outcomes in spondylodiscitis patients treated in our Emergency Department. PATIENTS AND METHODS: The present investigation represents a single-center retrospective study. Clinical records of consecutive patients admitted to our Emergency Department from 1 January 2015 to 31 March 2021 were evaluated and patients with spondylodiscitis diagnosis in this period were recruited. Our primary outcome was the degree of autonomy of patients following the acute event. Our secondary outcome was the resolution of the infection. RESULTS: In the study period, a total of 345 patients were evaluated. Among these, 165 met the inclusion criteria, and constituted the study cohort. Concerning the primary outcome, we observed that the most significant predictive factors for being non-autonomous were elevated serum creatinine (> 1.05 mg/dl), Blood Urea Nitrogen (BUN) > 23 mg/dl, Lactate dehydrogenase > 228 U/L, PCT > 0.11 ng/mL. Patients with higher PCT (PCT > 0.11 ng/mL) and higher BUN (BUN > 23 mg/dl) had higher odds of infection persistence (the Odd Ratio, OR, were respectively 3.78 for PCT and 3.14 for BUN). CONCLUSIONS: PCT assay may play a role in diagnosing spondylodiscitis in an emergency setting. A PCT value > 0.11 ng/mL should be considered as a red flag, a predictor of worse clinical outcomes and persistence of infection.

Liner dissociation in total hip arthroplasty: a systematic review.

OBJECTIVE: Liner dissociation (LD) is a rare catastrophic mechanical failure of total hip arthroplasty (THA). The study aims at reviewing the available literature regarding liner dissociations to point out their prevalence, describing any possible association and highlighting the surgical management at the time of revision. MATERIALS AND METHODS: A systematic review of the literature was conducted from January 2002, until February 2022, according to the PRISMA guidelines. The main keywords were: "dissociation" AND "liner" OR "hip arthroplasty" OR "THA" and their MeSH terms in any possible combination. Cases of liner dissociation with all levels of evidence of any age published in indexed journals were included. The study quality of all included studies was evaluated using the MINORS criteria. The kappa (k) value was used to assess the consensus between reviewers in the selection of articles and methodological quality assessment. Finally, a sub-analysis was performed specifically concerning the elderly population. RESULTS: Thirty-one manuscripts met the inclusion criteria of the systematic review (21 case reports and 10 case series). 124 LD in 123 patients, (53% females and 47% males) were evaluated. The overall prevalence of LD was 0.15%. The mean age at surgery was of 56.5 years (range 31-75 years). LD occurred in a primary surgery setting in 86% of the cases, at a mean time of presentation of 45.8 months after replacement surgery. 39.5% of the cups and 8.8% of the stems required revision. The mean follow-up after the revision was 18.4 months. Complications after revision occurred in 19.6% of cases, including 3 cases of re-dissociations. Re-revision was required in 13.6% of the revisions. The sub-analysis of the elderly population included 28 cases of LD identified in 10 manuscripts, with an average age of 73.5 years. CONCLUSIONS: LD is a rare but catastrophic mechanical complication of modular THA that requires implant revision. The LD is not related to a specific prosthetic implant, liner material or design, acetabular positioning within the safe zone or age group.

Residual mobility after removal of instrumentation in patient, with type a2-a3 vertebral fractures, treated with percutaneous pedicle screw fixation.

Percutaneous techniques for treatment of thoraco-lumbar fractures type A2 and A3 are widely used. These techniques are considered temporary fixations and instrumentation must be removed with fracture healing. The aim of the study is to analyze clinical results, motility of treated segments and any loss of correction after the removal of instrumentation. We evaluated 36 patients who underwent surgery for removal of the instrumentation. Standard and dynamics x-ray before surgery and at 1 and 12 months after surgery were obtained. Radiographic evaluation was performed by comparing loss of correction after removal of the instrumentation, residual mobility of fractured vertebra, upper and lower level with values defined by Dvorak. For clinical assessment were used SF-12, Oswestry Disability Index (ODI) and Visual Analog Scale (VAS), administered before surgery and at 1 and 12 months after the removal. We analyzed a total of 108 levels in 36 patients. After removal of the instrumentation a normal range of motion was restored in the proximal and distal segment of the fracture, while at level of fractured segment we noticed a decrease in motility. Clinically, patients had a significant decrease in VAS and ODI at 1 month after removal. Our study shows that percutaneous fixation for treatment of thoraco-lumbar fractures type A2 and A3, allows to preserve motility of the treated segments after the removal of the instrumentation until 12 months. The removal of instrumentation is associated with good clinical results without of loss of correction in treated segment.

The Feasibility of Long-Segment Fluoroscopy-guided Percutaneous Thoracic Spine Pedicle Screw Fixation, and the Outcome at Two-year Follow-up.

Introduction: Posterior percutaneous instrumentation may represent a challenge when multiple levels need to be instrumentated, especially when including the upper thoracic spine. The aim of the present study was to evaluate the technical feasibility and the long-term outcome of such long constructs in different surgical conditions. Materials and Methods: This investigation was a retrospective cohort study which included patients who underwent thoraco-lumbar percutaneous fixations. We collected clinical, surgical and radiological data, with a minimum follow-up of 24 months. Health-related quality-of-life, residual pain, instrumentation placement, and complications were studied. Results: A total of 18 procedures were enrolled, in which 182 screws were implanted, (170 positioned in thoracic and 12 in lumbar pedicles, respectively). No surgical complications or hardware failure occurred in our series, 6 out of 182 (3,2%) screws had a partial pedicle breach, without neurological impairment or need for surgical revision. Conclusion: According to our results, a fully posterior percutaneous approach for long thoraco-lumbar spine instrumentation can be considered safe and reproducible, although an adequate training is strictly required.

Medical management of acute non-specific low back pain: comparison of different medical treatments, one center's retrospective analysis.

Within the developed countries, low back pain and related ailments represent one of the most relevant conditions, affecting both health and socio-economic systems. Non-specific acute low back pain (nsALBP) could represent either an isolated event or the presenting symptom of an underlying condition. Its management is usually medical and radiological investigations should be avoided. However, a general agreement on the best pharmacological treatment is still missing. In the present study, we retrospectively collected patients' data from the institutional database. Two different medical treatments were recognized and groups consequently set. Outcomes were the clinical status, measured using the visual analogue scale (VAS) score for back pain, the use rate of rescue drugs, side effects related to medical treatment, compliance to the treatment, and global satisfaction. The pharma blending of Tramadol 75 mg and Dexketoprofen 25 mg (available blended in a single tablet), resulted effective in the nsALBP management, with less side effects and rescue-drug use along with a higher compliance. Furthermore, patient satisfaction in this treatment group was significatively higher. Many different medical treatments have been investigated and reported in nsALBP management during the last decades. Associations of different drugs are the most common protocols, even though there is no general agreement. Tramadol and Dexketoprofen provide a good clinical result, fewer side effects and a long-lasting and more effective painkiller action, reducing the use of rescue drugs. Moreover, our results suggest that a single tab may provide a higher compliance rate.

Nonsurgical treatment of Mason type II radial head fractures in athletes. A retrospective study.

OBJECTIVE: The best treatment for moderately displaced radial head fractures (Mason type II) still remains controversial. In cases of isolated fractures, there is no evidence that a fragment displacement of ≥ 2 mm gives poor results in conservatively treated fractures. PATIENTS AND METHODS: We retrospectively reviewed 52 patients (31M, 21F) affected by an isolated Mason type II fracture, treated with a long arm cast for two weeks between 2008 and 2013. All patients had practiced sports before being injured. They were all either bicyclists, or baseball, boxers, basketball, rugby, tennis or football players. The mean follow-up was 36 months. Elbow and forearm range of motion were measured. The Mayo Elbow Performance Score, the Broberg and Morrey rating system and the Disabilities of the Arm, Shoulder and Hand Score (DASH score) were analyzed. Follow-up radiographs were examined for evidence of consolidation, late displacement, early arthritis and non-unions. RESULTS: Flexion was slightly impaired in the injured limb when compared to the uninjured limb (137°± 6° versus 139°±5°) as were extension (-3°±6° versus 1°±4°, p < 0.05), supination (86°±6° versus 88°±3°), pronation (87°±4° versus 88°±6°) and valgus deviation (10°±4° versus 8°±3°, p < 0.05). 40 patients had no elbow complaints; 9 patients experienced occasional pain, 2 a mild instability of the elbow, and 4 a mild loss of grip strength. The DASH score was excellent in 48 patients (92.31%). In only 6 cases (11.53%) degenerative changes were greater in formerly injured elbows than in uninjured elbows. All patients returned to their previous sports activities. CONCLUSIONS: Isolated Mason type II fractures can have a good or excellent mid-term functional outcome even when treated conservatively.

Degenerative facet joint changes in lumbar percutaneous pedicle screw fixation without fusion.

BACKGROUND: Aim of the study was to evaluate degenerative lumbar facet-joints changes after percutaneous pedicle screw fixation (PPSF) in the treatment of lumbar fractures. MATERIALS AND METHODS: Thirty patients underwent short PPSF without fusion. CT-scan was performed in the pre- and post-operative time at four, eight and 12 months. The six zygapophyseal joints adjacent the fracture's level were evaluated. RESULTS: At four months patients showed no differences between pre- and post-operative joint radiographic aspect. At eight and 12 months, CT-scan demonstrated a progressive degeneration only in the middle joints respectively in 21.42% and in 76.92% of the cases. All 10 disrupted facet joints showed progressive degenerative changes at eight and 12 months. CONCLUSION: Lumbar percutaneous fixation without fusion induces little degenerations essentially collocated in the middle joints close to fracture level at eight and 12 months. In the proximal and distal joints adjacent the screws degenerative changes can be seen only when associated to pedicle-screw encroachment.

Paracetamol-codeine compared to ketorolac for pain control in the Emergency Department.

OBJECTIVE: Paracetamol /codeine has shown a strong analgesic activity in several studies conducted among different kind of subjects, including those with trauma. Nevertheless, its efficacy in patients accessing the Emergency Department (ED) for different kind of pain has never been tested. PATIENTS AND METHODS: This is a cross-sectional, observational, prospective, cohort study. Inclusion criteria were patients > 18 year old presenting to the ED for localized traumatic or inflammatory pain involving only extremities. Numeric scale (NRS) was recorded thirty minutes and two hours after the administration of the analgesic therapy, consisting of 15 mg of ketorolac or 1000 mg/60 mg of paracetamol/ codeine, both orally. RESULTS: Two-hundred patients were consecutively enrolled; 87 were treated with paracetamol/codeine and 113 with ketorolac. The combination paracetamol/codeine resulted to be not inferior to ketorolac in non-traumatic pain group and trauma group (p = 0.635 and p = 0.482, respectively). Compared to ketorolac, the combination paracetamol/codeine exerted a significantly higher analgesic activity in patients with fractures and muscular pain (p = 0.044) and was more effective in acute pain (p = 0.002), with a significant effect two hours after the administration (p = 0.029). CONCLUSIONS: Paracetamol/codeine is equivalent to ketorolac in non-traumatic pain and post-traumatic pain, but is superior in acute pain and in patients with fractures and muscular pain. Those results play in favor of the use of the combination paracetamol/codeine in patients accessing the ED for non-traumatic or traumatic pain of the extremities.

The impact of sagittal balance on low back pain in patients treated with zygoapophysial facet joint injection.

INTRODUCTION: Aim of the study was to evaluate the effectiveness of facet joints injections in lumbar facet syndrome correlating clinical results to the sagittal contour of the spine. METHODS: Facet joints degree degeneration was evaluated using MRI according to Fujiwara classification. Sagittal contour of the spine was evaluated according to Roussouly classification. The clinical results were evaluated with visual analog scale (VAS) at regular intervals. RESULTS: Twenty-eight (70 %) of the 40 patients had clinical symptoms improvement, 12 (30 %) showed no benefit. There was a statistical significant correlation between postoperative VAS value improvement and Roussouly spine type 1 and 3 (p = 0.003). The benefit was more durable in patients with grade 2 or 3 degeneration. CONCLUSIONS: Facet joints injections have a more effective diagnostic than therapeutic value. The procedure could, however, give a temporary pain relief in cases with an overload of the facet joints due to lumbar hyperlordosis.

Posterior percutaneous reduction and fixation of thoraco-lumbar burst fractures.

BACKGROUND: Treatment of A3 thoraco-lumbar and lumbar spinal fractures nowadays remains a controversial issue. Percutaneous techniques are becoming very popular in the last few years to reduce the approach-related morbidity associated with conventional techniques. HYPOTHESIS: Purpose of the study was to analyze the clinical and radiological outcome of patients who underwent percutaneous posterior fixation without fusion for the treatment of thoraco-lumbar and lumbar A3 fractures. MATERIALS AND METHODS: Sixty-three patients, having sustained a single-level thoraco-lumbar fracture, underwent short segment percutaneous instrumentation and were retrospectively analyzed. sagittal index (SI) was calculated in all patients. Clinical and functional outcome were evaluated by Visual Analog Scale (VAS), Oswestry Disability Index (ODI) and Short Form General Health Status (SF-36). RESULTS: Average operative blood loss was 82 mL (50-320). Mean pre-operative SI in the thoraco-lumbar segment was 13.3° decreased to 5.8° in the immediate postoperative with a mean deformity correction of 7.5. Mean pre-operative SI in the lumbar segment was 16.5° decreased to 11.3° in the immediate postoperative with a mean deformity correction of 5.2. Not statistically significant correction loss was registered at 1-year minimum follow-up. Constant clinical conditions improvement in the examined patients was observed. CONCLUSION: Percutaneous pedicle screw fixation for A3 thoraco-lumbar and lumbar spinal fractures is a reliable and safe procedure. LEVEL OF EVIDENCE: Level IV. Retrospective study.

Percutaneous pedicle screw fixation in polytrauma patients.

PURPOSE: The clinical outcome of polytrauma patients underwent spine fixation was analyzed and correlated both to surgical time (early versus delayed) and to fixation type (open versus percutaneous). METHODS: Twenty-four polytrauma patients were retrospectively evaluated. Patients were evaluated according to age, accident dynamic, mechanical ventilation need, blood transfusion need, SAPS II score, type of vertebral injury, time of fixation (within or after 72 h) and type of fixation. RESULTS: Nine patients underwent percutaneous pedicle screw fixation and 12 open fusion. An early fixation allows better clinical outcome considering ICU stay (13.7 versus 21.71 days), H-LOS (25.8 versus 69.5 days), mechanical ventilation need (7 versus 16.2), blood transfusion need (250 versus 592 cc). CONCLUSIONS: In polytrauma patients an early spine fixation improves clinical outcome. Patients underwent percutaneous screw fixation showed a better outcome compared to open surgery group obtained despite worst clinical conditions.

Cervical myelopathy due to ossification of the transverse atlantal ligament: a Caucasian case report operated on and literature analysis.

One case of cervical myelopathy associated to ossification of transverse atlantal ligament (OTAL) and C1 posterior arch hypoplasia in a Caucasian adult female is reported. A 53-year-old female affected by cervical myelopathy was treated with C1 laminectomy and posterior arthrodesis. CT scan demonstrated that the distance between ossification of the ligament and anterior cortex of the posterior arch of atlas was 6,2mm leading to consistent space reduction for spinal cord at this level. Patient underwent spinal cord decompression and fixation with C1 poliaxial screws in lateral masses and two bilateral crossing C2 laminar screws with an improvement of neurological functions at 4-years follow-up. The association between OTAL and C1 hypoplasia was reported in very few cases. The treatment with C1 laminectomy without fusion is reported in medical literature with good clinical outcome. Our patient obtained a neurological improvement at midterm follow-up with spinal cord decompression and fusion.

Bisphosphonate therapy in multiple myeloma in preventing vertebral collapses: preliminary report.

PURPOSE: The aim of the study was to report and discuss the preliminary data obtained in a homogeneous series of 50 patients affected by multiple myeloma treated with bisphosphonates. METHODS: Patients were followed for a minimum of 1 year. Main orthopaedic data were recorded. Visual Analogue Score and QLQ-C30 and MY 20 were used to assess the quality of life. RESULTS: Statistical analysis showed less lytic lesions in the group with zoledronate therapy and stable primary disease compared with a greater number of lesions in the non-treated group. Results regarding VAS score and QLQ-C30 and MY were statistically better in the first group than in the second. CONCLUSIONS: Our results confirm the efficacy of zoledronate in ensuring an acceptable quality of life restraining the aggressiveness of the myeloma on bone tissue, especially in spine although further prospective studies have to be conducted to determine its correct use in myeloma patients.

Transdiscal L5-S1 screws for the treatment of adult spondylolisthesis.

PURPOSE: The aim of the study was to evaluate clinical and radiographic outcome of patients treated with a modified Grob technique analysing the advantages related to increased mechanical stability. METHODS: 30 patients that underwent "in situ" fusion for L5-S1 spondylolisthesis were evaluated. All patients presented a low-dysplastic developmental L5-S1 spondylolisthesis. Patients were divided into two groups: A, in which L5-S1 pedicle instrumentation associated with transsacral screw fixation was performed, and B, in which L5-S1 pedicle instrumentation associated with a posterolateral interbody fusion (PLIF) was performed. RESULTS: Patients treated with transdiscal L5-S1 fixation observed a faster resolution of the symptoms and a more rapid return to daily activities, especially at 3-6 months' follow-up. The technique is reliable in giving an optimal mechanical stability to obtain a solid fusion. CONCLUSIONS: The advantages of this technique are lower incidence of neurologic complications, speed of execution and faster return to normal life.
