RESUMO
BACKGROUND: Capacitively coupling electric fields (CCEF) is a method of non-invasive biophysical stimulation that enhances fracture repair and spinal fusion. This multicentre randomized controlled trial aimed to further examine the roles of CCEF in (1) the resolution of vertebral bone marrow oedema (VBME) using a follow-up MRI study and (2) pain relief, analgesic drug consumption and quality of life improvement in stimulated patients who were referred with acute vertebral fragility fractures (VFFs) compared to non-stimulated patients. METHODS: Between September 2016 and December 2019, patients who were referred to the spine centres that participated in this multicentre randomized clinical study with acute VFFs of type OF1 or OF2 were included in the present study. All the VFFs were conservatively managed according to Good Clinical Practice. Moreover, the patients were randomized into two groups: the CCEF group received, as an adjunct to the clinical study protocol, biophysical stimulation with a CCEF device (Osteospine, IGEA) for 8 h per day for 60 days, whereas the control group was treated according to the clinical study protocol. At baseline (T0), the 30-day follow-up (T1), the 60-day follow-up (T2), and the 6-month follow-up (T3), each patient underwent clinical evaluation using the Visual Analogue Scale (VAS) for Pain and the Oswestry Disability Index (ODI). Analgesic therapy with paracetamol 1000 mg tablets for 7 days-or longer, depending on the pain intensity-was performed; patients were required to report their paracetamol consumption on a specific sheet between study day 8 to 180 days of follow-up. MRI studies of the thoracolumbar spine were performed at 0 (T0), 30 (T1) and 60 days of follow-up (T2) using a 1.5-T MRI system in all of the centres that took part in the study. For each VBME area examined via MRI, the vertebral body geometry (i.e. anterior wall height/posterior wall height and vertebral kyphosis) were assessed. RESULTS: A total of 66 patients (male: 9, 13.63%; mean age: 73.15 years old) with 69 VFFs were included in the present study and randomized as follows: 33 patients were included in the control group and the remaining 33 patients were randomized into the CCEF group. In the CCEF group, good compliance with CCEF therapy was observed (adherence = 94%), and no adverse effects were recorded. In the stimulated patients, faster VBME resolution and significantly less vertebral body collapse during follow-up were observed compared to the control patients. Moreover, in the active group, faster pain reduction and improvement in the ODI mean score were observed. Stimulated patients also reported a significantly lower paracetamol consumption rate from the third follow-up after treatment until the 6-month follow-up. In terms of sex-related differences, in the CCEF group, VBME showed a faster resolution in male patients compared with females. CONCLUSION: Biophysical stimulation with CCEF, as an adjunct to traditional conservative treatment, is a useful tool to hasten the VBME resolution process and prevent vertebral body deformation. These MRI findings also correlate with faster back pain resolution and quality of life improvement. From the third follow-up after treatment until the 6-month follow-up, stimulated patients reported a significantly lower paracetamol consumption than control patients, even though back pain and quality of life showed no significant differences between the two groups. LEVEL OF EVIDENCE: II. Trial Registration Register: ClinicalTrials.gov, number: NCT05803681.

Polydeoxyribonucleotide (PDRN) is a proprietary and registered drug with several beneficial effects, including tissue repairing, anti-ischemic action, and anti-inflammatory properties. The present study aims to summarize the current evidence about PRDN's clinical effectiveness in the management of tendon disorders. From January 2015 to November 2022, OVID-MEDLINE®, EMBASE, Cochrane Library, SCOPUS, Web of Science, Google Scholar and PubMed were searched to identify relevant studies. The methodological quality of the studies was evaluated, and relevant data were extracted. Nine studies (two in vivo studies and seven clinical studies) were finally included in this systematic review. Overall, 169 patients (male: 103) were included in the present study. The effectiveness and safeness of PDRN has been investigated in the management of the following diseases: plantar fasciitis; epicondylitis; Achilles tendinopathy; pes anserine bursitis; chronic rotator cuff disease. No adverse effects have been recorded in the included studies and all the patients showed an improvement in clinical symptoms during the follow-up. PDRN are a valid emerging therapeutic drug in the treatment of tendinopathies. Further multicentric randomized clinical studies are needed to better define the therapeutic role of PDRN, especially in combined clinical protocols.

BACKGROUND: Intertrochanteric and subtrochanteric non-union are rare but challenging complications. In the present study, we investigate the use of a 95° blade, in association with biological and mechanical augmentation, in the management of intertrochanteric and subtrochanteric femoral non-unions. METHODS: Between October 2015 and February 2021, a retrospective cohort study was conducted at our institution to investigate the use of a 95° blade, in association with biological and mechanical augmentation, in the management of intertrochanteric and subtrochanteric femoral non-unions, following the mechanical failure of the first device. All the patients underwent a clinical and radiographic follow-up at 6 weeks, 3, 6, 9, 12 and 18 months; at each follow-up, a plain radiograph of the femur was performed and patients were assessed using Harris Hip Score (HHS) and the Short Form-12 (SF-12) questionnaire. RESULTS: From October 2015 and February 2021, 40 proximal femur non-unions were managed at our Institution. Fifteen patients out of forty (37.5%) met the inclusion criteria. The main data of the study are summarized in Table 1; patients' mean was 57 years old (range 19-83); 10 males and 5 females were included in the study. All the patients completely healed clinically and radiologically at an average of 6.1 months (range 4-13). All these patients returned to their pre-injury mobility status. During an average follow-up period of 25 months (range 8-60), the observed complications included wound dehiscence, which was treated with a superficial surgical debridement, a below-the-knee deep vein thrombosis, and a blade plate failure 3 months after the first revision surgery. CONCLUSIONS: This study shows the treatment of inter-and sub-trochanteric non-unions with a 95° blade plate, medial strut allograft, and bone autograft obtained with RIA system, together with a varus malalignment correction, leads to a high percentage of bone healing, with a low incidence of complications and good clinical outcome.

Osteoarthritis (OA) is a joint degenerative disease that most affects old age. The study of proteomics in synovial fluid (SF) has the task of providing additional elements to diagnose and predict the progress of OA. This review aims to identify the most significant biomarkers in the study of OA and to stimulate their routine use. Some of the major components of the ECM, such as proteoglycan aggrecan and decorin, were found considerably reduced in OA. Some biomarkers have proved useful for staging the temporality of OA: Periostin was found to be increased in early OA, while CRTA1 and MMPs were found to be increased in late OA. In its natural attempt at tissue regeneration, Collagen III was found to be increased in early OA while decreased in late OA. Some molecules studied in other areas, such as ZHX3 (oncological marker), LYVE1, and VEGF (lymph and angiogenesis markers), also have been found to be altered in OA. It also has been recorded that alteration of the hormonal pathway, using a dosage of PPAR-γ and RETN, can influence the evolution of OA. IL-1, one of the most investigated biomarkers in OA-SF, is not as reliable as a target of OA in recent studies. The study of biomarkers in SF appears to be, in combination with the clinical and radiological aspects, an additional weapon to address the diagnosis and staging of OA. Therefore, it can guide us more appropriately towards the indication of arthroplasty in patients with OA.

Background and Objectives: Sex and gender-related differences may influence the outcome of patients undergoing total hip arthroplasty (THA). The present paper aims to depict the importance of sex and gender-related issues in the perioperative management of patients undergoing THA to improve clinical outcomes and prevent postoperative complications. Materials and Methods: From January 2002 to August 2022, OVID-MEDLINE, EMBASE, SCOPU S, Web of Science, Google Scholar, and PubMed were searched to identify relevant studies for further analysis. The search strategy included the following terms: (("gender-related differences" [MeSH Terms] OR "sex-related differences" [All Fields]) OR ("gender indicators" [MeSH Terms] OR "sex" [All Fields])) AND ("total hip arthroplasty" [MeSH Terms] OR (total hip replacement [All Fields])). Results: Twenty-eight papers were included in this current concepts review. Sex and gender-related differences were analyzed with regard to the following points: (1) surgical approach, robotic surgery, scar cosmesis, and implant choice; (2) postoperative clinical outcome and complications; (3) sexual activity after THA; and (4) psychological status and daily functional requirements. The data analysis showed that female patients need more specific attention in the preoperative, intraoperative, and postoperative phases to improve clinical and functional outcomes, reduce complications risk, and manage patient satisfaction. Conclusions: THA outcomes may be influenced by sex and gender-related factors which should be carefully assessed and addressed in patients undergoing surgery to improve the postoperative outcomes of patients' satisfaction and reduce postoperative complications that can differ between the two sexes.

OBJECTIVES: The purpose of this study is to evaluate Italian surgeons' behavior during knee arthroplasty. MATERIALS AND METHODS: All orthopedic surgeons who specialized in knee replacement surgeries and were members of the Italian Society of Knee, Arthroscopy, Sport, Cartilage and Orthopedic Technologies (SIGASCOT) between January 2019 and August 2019 were asked to complete a survey on the management of knee arthroplasty. Data were collected, analyzed, and presented as frequencies and percentages. RESULTS: One-hundred and seventy-seven surgeons completed the survey and were included in the study. Ninety-five (53.7%) surgeons were under 40 years of age. Eighty-five surgeons (48%) worked in public hospitals and 112 (63.3%) were considered "high volume surgeons", with more than 100 knee implants per year. Postero-stabilized total knee arthroplasty was the most commonly used, implanted with a fully cemented technique by 162 (91.5%) surgeons. Unicompartmental knee arthroplasty (UKA) was a rarer procedure compared to TKA, with 77% of surgeons performing less than 30% of UKAs. Most common TKA pre-operative radiological planning included complete antero-posterior (AP) weight-bearing lower limb radiographs, lateral view and patellofemoral view (used by 91%, 98.9% and 70.6% of surgeons, respectively). Pre-operative UKA radiological images included Rosenberg or Schuss views, patellofemoral view and magnetic resonance imaging (66.1%, 71.8% and 46.3% of surgeons, respectively). One hundred and thirty-two surgeons (74.6%) included an AP weight-bearing lower limb X-ray one year after surgery in the post-operative radiological follow-up. Furthermore, 119 surgeons (67.2%) did not perform a post-operative patellofemoral view because it was not considered useful for radiological follow-up. There was no uniformity in the timing and features of post-operative follow-up, with 13 different combinations. CONCLUSIONS: Italian surgeons perform TKA more commonly than UKA. Pre-operative TKA planning is quite uniform rather than UKA planning. Despite literature evidence, there is no agreement on follow-up. It may be useful to create a uniform checklist, including correct timing and exams needed. This analysis is also part of a society surgical educational project for training doctor.

BACKGROUND: Osteoporotic acetabular fractures frequently involve the quadrilateral plate (QP), a flat and thin bone constituting the medial wall of the acetabulum. This study aims to assess the impact of the quality of osteoporotic QP fractures reduction on the patients' functional recovery, at 24 months follow-up. METHODS: Patients referring with osteoporotic QP fractures to our Level I trauma centre were prospectively recruited. INCLUSION CRITERIA: patients aged 60 years old or older; osteoporosis, defined as Dual-energy X-ray Absorptiometry (DXA) T-score ≤ - 2.5; acute acetabular fracture; anatomic or good fracture reduction according to Matta on postoperative CT. EXCLUSION CRITERIA: moderate cognitive impairment (defined as Mini-Mental State Examination < 19); a history of malignant neoplasm; concomitant fractures in other sites; traumatic head injury; lower limb joint prostheses; patient not able to walk independently before trauma; poor fracture reduction, according to Matta, on postoperative CT. All the QP fractures were surgically managed. After surgery, the reduction of each QP fracture was classified as anatomical (displacement 0-1 mm), good (displacement 2-3 mm) and poor (displacement > 3 mm) on postoperative CT. Based on this classification: patients with a poor fracture reduction were excluded from this study, patients with an anatomical reduction were recruited in Group-A and patients with a good reduction in Group-B. All the patients underwent a clinical and radiographic 24-months follow-up. RESULTS: 68 patients (males 38; females 30; mean age 68.6 years old; range 60-79) were finally included in in the study. No cases of open fractures or concomitant pelvic ring fractures were observed. Based on the post-operative CT, 39 patients showed an anatomic fracture reduction (Group-A) while the remaining 29 patients revealed a good fracture reduction (Group-B). Complication rates and mean clinical scores showed no significant differences between groups, at 24-months follow-up. CONCLUSIONS: In this study, the functional recovery at 24 months follow-up showed no significant differences in elderly patients with QP fracture undergoing anatomical reconstruction (displacement 0-1 mm) compared to patients receiving a good QP fracture reconstruction (displacement ≤ 3 mm).

BACKGROUND: Total hip arthroplasty (THA) is currently the best surgical option for hip osteoarthritis secondary to developmental hip dysplasia (DDH); it may be extremely challenging, because of the hypoplasic proximal metaphysis, pathological anteversion, and excessive cervico-diaphyseal angle of the neck at the femoral side. The purpose of this retrospective study was to evaluate the long-term survival and clinical and radiological results of Conus uncemented stems, implanted in patients affected by hip osteoarthritis with Crowe not-type IV secondary to DDH. MATERIAL AND METHODS: We identified 100 consecutive THAs performed for DDH in 63 women and 24 men, with an average age of 53 years in a single center. Thirteen patients underwent bilateral hip replacement. The patients' mean body mass index was 29.8 kg/m2 (range 27.1-35.6 kg/m2). The main indications for surgery were severe hip pain and considerable functional impairment: the preoperative Harris Hip Score was 29.5 on average (range 22-61). Radiologically, 8 hips were classified as Crowe I, 43 hips as Crowe II, and 49 hips as Crowe III. In all cases, we implanted the Wagner femoral cone prosthesis using the direct lateral approach; in the attempt to reestablish native hip biomechanics, 66 stems were 135° and 34 were 125°. RESULTS: The mean follow-up of the study was 11.7 years (range 2.2-21.8 years). Harris Hip Score increased to a mean value of 71.5 points (range 52-93 points). Radiographic evaluation demonstrated osteointegration of the implant with stable bone growth observed at the stem-endosteum interface; signs of bone readaptation and thinning of the femoral calcar were present in nine hips. None of the patients underwent revision for septic or aseptic loosening of the stem; none sustained a periprosthetic fracture. CONCLUSIONS: This study confirms the theoretical advantages that suggest the choice of the Wagner cone when technical difficulties during prosthetic surgery are expected owing to abnormal proximal femoral anatomy. LEVEL OF EVIDENCE: Level IV, retrospective case study.

AIM: To assess the outcome of augmentation techniques, i.e., percutaneous vertebroplasty (PVP), balloon kyphoplasty (BKP), vertebral body stenting (VBS) and fixation techniques in the management of vertebral fragility fractures (VFFs). METHODS: OVID-MEDLINE®, EMBASE, Cochrane Library, SCOPUS, Springer Link, Web of Science, Google Scholar and PubMed were searched from January 2009 to February 2019 to identify relevant studies. The methodological qualities of the studies were evaluated and relevant data were extracted. RESULTS: Thirteen randomized controlled trials, recruiting 1963 patients, were included. PVP, compared with conservative management (CM), showed a greater pain relief and an improved vertebral body height (VBH) restoration. Moreover, PVP revealed superior to a sham procedure for pain relief in acute VFFs. BKP, compared with CM, rapidly reduces pain and improves quality of life without increasing the risk of additional VFFs. BKP, compared with PVP, has fewer cement leakage rates and is more effective in VBH restoration. BKP should also be preferred to VBS, since it is associated with less material-related complications. Pedicle screw fixation associated with PVP, compared with PVP alone, revealed effective in preventing secondary VFFs. CONCLUSIONS: BKP showed better clinical and radiological outcomes compared with CM and PVP. BKP revealed as effective as VBS in VBH restoration with less material-related complications.

BACKGROUND: From February 21, the day of hospitalisation in ICU of the first diagnosed case of Covid-19, the social situation and the hospitals' organisation throughout Italy dramatically changed. METHODS: The CIO (Club Italiano dell'Osteosintesi) is an Italian society devoted to the study of traumatology that counts members spread in public and private hospitals throughout the country. Fifteen members of the CIO, Chairmen of 15 Orthopaedic and Trauma Units of level 1 or 2 trauma centres in Italy, have been involved in the study. They were asked to record data about surgical, outpatients clinics and ER activity from the 23rd of February to the 4th of April 2020. The data collected were compared with the data of the same timeframe of the previous year (2019). RESULTS: Comparing with last year, overall outpatient activity reduced up to 75%, overall Emergency Room (ER) trauma consultations up to 71%, elective surgical activity reduced up to 100% within two weeks and trauma surgery excluding femoral neck fractures up to 50%. The surgical treatment of femoral neck fractures showed a stable reduction from 15 to 20% without a significant variation during the timeframe. CONCLUSIONS: Covid-19 outbreak showed a tremendous impact on all orthopaedic trauma activities throughout the country except for the surgical treatment of femoral neck fractures, which, although reduced, did not change in percentage within the analysed timeframe.

BACKGROUND: Ceramic-on-ceramic (CoC) bearings due to their mechanical properties can be used in primary total hip arthroplasty (THA) especially in young patients requiring a long-lasting implant. The goal of this study is to analyze the results of a series of 200 consecutive CoC THAs in patients aged 50 years or less at the time of surgery. METHODS: A retrospective study was conducted on the first 200 consecutive CoC arthroplasties performed using the direct lateral approach on 105 females and 81 males (14 bilateral cases) with an average age of 44.2 (16-50) years. The diagnosis was primary or post-traumatic osteoarthritis in 94 cases, avascular necrosis of the femoral head in 47, displaced intracapsular femoral neck fracture in 29, osteoarthritis secondary to developmental dysplasia of the hip/Legg-Calvè-Perthes disease/slipped capital femoral epiphysis in 20, and rheumatic diseases in 10 cases. The preoperative Harris Hip Score was 32.5 on average (range 15-55). All the implants were cementless. In 177 THAs the coupling was alumina-on-alumina, and in 23 cases the coupling was AMC-on-AMC (alumina matrix composite). RESULTS: Twenty-five patients with 28 THAs were lost at the final follow-up, 2 stems were revised due to subsidence, 1 cup was revised due to malposition, 1 femoral head was changed because of impingement, and 1 THA was revised for periprosthetic infection. Three patients sustained a Vancouver B1 periprosthetic femoral fracture. At the final follow-up (mean 14.9 years; minimum 5 years to maximum 24 years), 172 THAs were eligible for clinical and radiographic evaluation: none was revised for wear and/or breakage of the ceramic components. Harris Hip Score rose up to a mean value of 90.1 (52-100). CONCLUSION: The present report demonstrates that CoC coupling offers excellent long-term results in THA performed in young patients with very low wear and no adverse effects caused by the material.

INTRODUCTION: Nail dynamization is one of the proposed surgical options to manage femoral shaft non-union. This study aims to assess the efficacy and the ideal timing for dynamization in patients with femoral shaft delayed union or non-union. MATERIAL AND METHODS: Sixty-eight patients (38 male and 30 female, mean age 36.85 years old, range 22-58) were recruited. The patients were divided into three groups according to the fracture healing time: groupa A, fracture healing occurred within nine months; group B, fracture healing occurred between nine and 12 months; and group C, fracture healing after 12 months or secondary procedure needed for union. Callus-to-diaphysis ratio was calculated on femur X-rays at the time of dynamization. RESULTS: In 30 patients out of 68, the fracture healing was observed at nine month follow-up; in 26 patients, the fracture healed within 12 months; eight fractures healed in more than 12 months and only four fractures required a secondary procedure for union. Dynamization was successful in 64 patients out of 68 (94.12%). The mean callus-diaphysis ratio was significantly different in group A (p = 0.001) and in group B (p = 0.03), compared with group C. The timing of dynamization resulted significantly different between the three groups. Linear regression analysis revealed that nail dynamization should be performed between three and six months after trauma. The optimal callus-to-diaphysis ratio should be comprised between 1.47 and 1.19, at the time of dynamization. DISCUSSION: Nail dynamization revealed safe and effective in the treatment of femoral delayed union and non-union. It should be considered as a first-line treatment for femoral non-union or delayed union.

INTRODUCTION: Femoral shaft fractures with third fragments have a high non-union rate, which may reach 14%. This study aims to assess the impact of the radiological features of the third fragment, evaluated on post-operative X-rays, on the outcome of femoral shaft fractures type 32-B managed with intramedullary nailing, in order to obtain an algorithm which could predict the fracture healing time. MATERIALS AND METHODS: We have retrospectively evaluated a series of 52 patients. On post-operative X-rays, four radiological parameters were evaluated: the third fragment angle, the fracture gap, the third fragment size, and the mean third fragment displacement. All the patients underwent a radiologic follow-up at one, two, three, six, nine and 12 months post-operatively, to assess the bone healing. The patients were then divided into three groups, according to the fracture healing time: within six months (group A), between six and 12 months (group B), or fracture non-union after 12 months (group C). RESULTS: In 28 patients, out of 52 (53.85%), the fracture healing was observed at 6-month follow-up; in 18 patients, out of 52 (34.62%), the fracture healed within 12 months after trauma; and in six patients, out of 52 (11.54%), no fracture healing was observed at 12-month follow-up. The mean third fragment size was significantly different in each group (p < 0.05), while the mean third fragment displacement was significantly higher in group C, compared with group A (p = 0.0006) and group B (p = 0.0027). In group B, a positive correlation was found between the fracture healing time and the mean third fragment size (R = 0.594, p = 0.036); in group C, the fracture union time was positively related to the third fragment size (R = 0.689, p = 0.013) and the mean third fragment displacement (R = 0.7107, p = 0.006). Regression analysis showed that the third fragment size and the mean third fragment displacement are the most important features which affect the fracture healing time. CONCLUSIONS: The third fragment size (cutoff 40 mm) is the leading parameter to influence the fracture healing within or in more than six months. The mean third fragment displacement (cutoff 12 mm); on the other hand, impacts on the fracture delayed rather than absent healing.

PURPOSE: To investigate if bone substitutes are strictly necessary to restore the vertebral body height and improve the clinical outcome, in patients with thoracolumbar or lumbar AO type A post-traumatic vertebral fractures, managed with balloon kyphoplasty combined with posterior screw and rod system. METHODS: 105 patients with post-traumatic thoracolumbar spine fracture were recruited. At baseline, the patients underwent a CT and an MRI of the spine. Clinical evaluation was performed, using the Visual Analog Scale (VAS) and the Oswestry Disability Index (ODI), at baseline, 48 h after surgery, at 3-month follow-up (FU), 6-month FU, 48 h after the instrumentation removal and at 24-month FU. At each FU, VK, regional kyphosis (RK), central wall (MH/PH) and anterior wall (AH/PH) heights were assessed on lateral spine X-rays. At 6-month FU, a CT scan of the spine was performed to investigate the fracture healing. The posterior instrumentation was removed 7 months after surgery (range 6-10 months). RESULTS: A significant reduction of mean VAS (p < 0.05) and ODI (p < 0.05) was observed after surgery; no impairment of these scores was observed after the instrumentation removal. A significant correction of VK, RK, AH/PH and MH/PH was recorded after surgery; no significant changes of these values were noticed at subsequent FU. After the instrumentation removal, only an RK impairment was recorded, but it was not significant. CONCLUSIONS: PMMA or bone substitutes are not necessary to keep the reduction of the endplate obtained with the balloon tamp, when BK is performed in the association with posterior percutaneous pedicle screws instrumentation. These slides can be retrieved under Electronic Supplementary Material.

PURPOSE: The study of the interrelation between hip and spine disorders is gaining increasing importance in the last years, but the link between Hip Osteoarthritis (HOA) and Low Back Pain (LBP) remains still unclear. Aim of the study is to assess the relationship between Femoral Neck Anteversion (FNA), LBP, and spinopelvic parameters in patients undergoing Total Hip Replacement (THR) for unilateral severe primary HOA. MATERIALS AND METHODS: 91 patients were recruited. Inclusion criteria were: grade 5 or 6 unilateral HOA, according to Turmezei, and Harris Hip score (HHS) <60. Exclusion criteria were: secondary hip osteoarthritis (dysplasia of the hip, rheumatoid arthritis, and ankylosing spondylitis); previous surgery of the spine, hip or knee; scoliosis with a Cobb angle greater than 10°; spondylolisthesis; history of spine fractures; previous bone tuberculosis or any spine infections; any contraindications to CT; BMI >30. Patients were divided into two homogeneous Groups according to the presence (Group-A) or not of concomitant LBP (Group-B). All patients underwent preoperatively a hip CT scan to evaluate FNA, Acetabular Anteversion (AA), and Combined Anteversion (CA = FNA + AA). ΔFNA, ΔAA and ΔCA were calculated as the differences between the arthritic hip and the normal hip angles in each Group. Full spinal X-rays in upstanding position were performed before (baseline) and 6 months after THR (follow-up) to calculate spinopelvic parameters. The health-related quality of life (HRQoL) was evaluated at baseline and at follow-up using Visual Analogue Scale (VAS), HHS, Oswestry Disability Index (ODI), Roland-Morris Disability Questionnaire (RM), and Short-Form Health Survey (SF-36). The intra-group and inter-group variability were assessed using, respectively, paired and unpaired t tests. At baseline, the association between HRQoL scores and ΔFNA, ΔAA, and ΔCA was analysed by the Pearson correlation test. RESULTS: At baseline, in Group-A, there was a significant difference between arthritic FNA and normal hip FNA, while no differences were found in AA between the two hips. A close correlation was observed between ΔFNA and Spine-VAS (r = 0.788), ODI (r = 0.824), and RM (r = 0.775). In Group-B, there was not a significant difference in FNA and AA between the two hips. At recruitment, in Group-A patients, we recorded a higher LL, SS, PI, SVA(C7), and a lower PT and T1-SPI compared with Group-B subjects. Six months after THR, in Group-A, an improvement of all clinical scores was recorded, as well as, a significant reduction of SS, LL, T1PA, and SVA(C7) and an increment of PT. In Group-B, at follow-up, an improvement of HHS, Hip-VAS, and SF-36 was recorded, while the changes in spinopelvic parameters were not significant. CONCLUSIONS: Patients with concomitant unilateral HOA and LBP showed a marked anteverted FNA in the arthritic hip and a spinopelvic misalignment. After THR, a relief of both hip and low back pain and a change in spinopelvic parameters is observed.

BACKGROUND: Total hip replacement for high dislocation of the hip presents some difficulties, considering patients' young ages, the abnormal hip anatomy and the high rate of complications. In this study, we present our experience in terms of clinical and radiological results in the treatment of Crowe type IV hips with subtrochanteric femoral shortening osteotomy and cementless total hip replacement. MATERIALS AND METHODS: We retrospectively reviewed 15 patients with Crowe type IV hip dysplasia (two bilateral cases for a total of 17 hips) treated with cementless total hip replacement associated with shortening subtrochanteric osteotomies (nine transversal and eight Z-shape osteotomies) between March 2000 to February 2006. The mean follow-up was 88 months (range 63-133). Harris hip score, leg length discrepancy, neurological status, union status of the osteotomy and the component stability were the criteria of the evaluation. All complications were noted. RESULTS: The mean HHS improved from 38.3 (range 32-52) to 85.6 (range 69-90). The mean preoperative leg length discrepancy was of 45 mm (range 38-70) and reduced to a mean of 12 mm (range 9-1.6) postoperatively. All osteotomies resulted healed at an average of 12.3 weeks (range 10-15). No cases of delayed union or nonunion were detected. Two patients (11%) showed early symptoms of sciatic nerve palsy which resolved uneventfully in 6 months. There was no migrations and none of the implants required revision. CONCLUSIONS: Cementless THA with shortening subtrochanteric osteotomy is an effective method in the treatment of patients with Crowe type IV development dysplasia of the hip. LEVEL OF EVIDENCE: IV.

PURPOSE: To evaluate the clinical outcomes of radial head excision for multifragmentary radial head fracture in patients over 65 years old. METHODS: We retrospectively examined 30 patients over 65 years of age treated with radial head excision for comminuted radial head fractures. Patients were evaluated through clinical examinations, administrative questionnaires (DASH--Disabilities of the Arm, Shoulder and Hand; MEPS--Mayo Elbow Performance Score, VAS--Visual Analog Scale) and plain films. RESULTS: The mean follow-up was 40 months (range 24-72 months); 27 out of 30 patients claimed to be satisfied. The mean DASH score was 13 (range 3-45.8) and mean MEPS was 79 (range 65-97). The radiographic evaluation showed 21 cases of elbow arthritis; only two of them complained about pain. Heterotopic ossification was evident in six cases with functional impairment in only one patient. Six patients with increased ulnar variance had clinical distal radio-ulnar joint instability. DISCUSSION: Radial head excision has been considered a safe surgical procedure with satisfactory clinical outcomes. Development in biomechanical studies and prosthetic replacement of the radial head question the validity of radial head excision. In current literature, there are neither long-term follow-up studies on radial head prosthesis outcomes nor studies which consider elderly patient samples. CONCLUSION: Radial head resection remains a good option when a radial head fracture occurs in elderly patients, taking into account the influence of poor bone quality and comorbidities on the outcome. Radial head excision is not indicated in the presence of associated lesions, because of the risk of residual elbow instability; complications associated with advanced age must be considered and a strict follow-up granted.

Fracture-related infections (FRIs), as shown in the literature, represent one of the main complications of trauma surgery. They are a consequence of an implant-related "biofilm" formation and are a challenge for surgeons, microbiologists, and infectious disease specialists. For a correct diagnosis, careful clinical evaluation, to look for signs/symptoms attributable to an infectious condition, and instrumental examinations, to highlight the site of infection, its extent, and its severity, are both essential. Unfortunately, due to the lack of data in the literature, there is no consensus about guidelines on the diagnosis and treatment of FRIs. The purpose of this study is to present an up-to-date concept evaluation of the diagnostic procedures and treatment options available in the management of fracture-related infections.
RESUMO
Background and Objective: Knee replacement following anterior cruciate ligament (ACL) reconstruction can be demanding due to altered anatomy, soft tissue scars, bone loss, extensor mechanism complications, and knee instability. This narrative review summarizes the strategies and approaches to managing operative challenges in total knee arthroplasty (TKA) following ACL reconstruction. Methods: Studies reporting outcomes of patients who underwent TKA after ACL reconstruction were retrieved and assessed to be included in this review that synthesizes the available evidence highlighting the pitfalls encountered during surgery, the intraoperative challenges posed by ligament balancing and exposure, and the leading role of modular and retained implants. Key Content and Findings: TKA following ACL reconstruction has a high rate of intra-operative complications such as instability, bone loss, difficult exposure and demanding soft tissue balancing, representing a revision surgery rather than routine primary knee arthroplasty and a revision-oriented skill set and modular components are recommended to significantly optimize both surgical strategy and patient outcomes. With a rising incidence of ACL injuries and growing reconstructions, anticipating an increase in TKA procedures, this review aims to provide a call for rethinking clinical approaches to ensure effective and patient-centric care. Conclusions: This narrative review seems to indicate that TKA after ACL reconstruction should be considered as revision surgery and modular components should be used. However, future prospective and high-quality studies are required to better clarify risk factors and give strong recommendations for this complex surgery.
