Functional outcome and complications after treatment of comminuted tibial fractures or deformities using Ilizarov bone transport: a single-center study at 15- to 30-year follow-up. Arch Orthop Trauma Surg 2021; 141:1825-1833. [PMID: 32734449 PMCID: PMC8497293 DOI: 10.1007/s00402-020-03562-9] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2020] [Accepted: 07/15/2020] [Indexed: 12/18/2022]
Abstract
INTRODUCTION The aim of this retrospective study was to evaluate long-term outcomes and complications of a single-center and single-surgeon patient series of isolated and comminuted tibial fractures with bone defects or tibial deformities treated by Ilizarov bone transport. MATERIALS AND METHODS Data from a consecutive series of patients with isolated comminuted tibial fractures (Fracture Group: FG) or deformities (Deformity Group: DG) treated between 1987 and 2002 were included. For clinical assessment, the Lower Extremities Functional Scale was used; complications were recorded according to the Dindo classification and statistical analysis was performed. RESULTS Overall, 72 patients were enrolled with a mean follow-up of 21.6 years (range 15-30) a mean LEFS of 36.4 (range 0-100). In the FG, the mean LEFS was 21.3 (range 0-98.75), and the external fixation time (EFT) lasted 7.6 months (range 3-18 months) months. In the DG, the mean LEFS was 76.7 (range 55-100), and the EFT was 10.6 months (range 3-20 months). Between the two groups, the clinical evaluation was significantly different, while the EFT was not (p = 0.14). In the FG, the worst results were obtained in the cases of open fractures with a higher percentage of complications and the need for further surgical procedures. The cumulative rate of complications was 55.6% during the first 36 months and 66.7% at the minimum follow-up of 180 months. CONCLUSIONS Ilizarov bone transport, even at a long follow-up period, proved to be an effective technique for both definitive treatment of comminuted tibial fractures with bone defects or tibial deformities. Although our functional outcomes were lower in patients with exposed fractures, they were in line with the literature, but not influenced by the EFT when properly managed. Most complications occurred during the first 3 years; however, they could also arise much later, even until almost 30 years.

Abstract
OBJECTIVE The infrapatellar fat pad (IFP) is considered a local producer of adipocytokines, suggesting a potential role in OA. The objective of this study was to evaluate the histopathological and molecular characteristics of OA IFPs compared with controls. METHODS The histopathological characteristics of IFPs were evaluated in patients undergoing total knee replacements and in control patients (without OA), considering the following parameters: presence of inflammatory cells, vascularization, adipose lobules dimension and thickness of the interlobular septa. Immunohistochemistry was performed to evaluate VEGF, monocyte chemotactic protein 1 (MCP-1) and IL-6 proteins. Quantitative real time PCR was performed to evaluate the expression levels of adipocytokines in the OA IFPs. RESULTS OA IFPs showed an increase in inflammatory infiltration, vascularization and thickness of the interlobular septa compared with controls. VEGF, MCP-1 and IL-6 proteins were higher in OA IFPs compared with in controls. Inflammatory infiltration, hyperplasia, vascularization and fibrosis were increased in OA IFP synovial membranes compared with in those of controls. VEGF protein levels were associated with an increased number of vessels in the OA IFPs, while MCP-1 and IL-6 protein levels were associated with higher grades of inflammatory infiltration. Leptin levels were positively correlated with adiponectin and MCP-1expression, while adiponectin positively correlated with peroxisome proliferative activated receptor gamma, MCP-1 and IFP vascularity. MCP-1 showed a positive correlation with peroxisome proliferative activated receptor gamma. IFP lobules dimensions were positively correlated with IL-6 expression and negatively with thickness of interlobular septa. VEGF mRNA levels were positively correlated with increased synovial vascularity. CONCLUSIONS OA IFPs and synovial membranes are more inflamed, vascularized and fibrous compared with those of control patients (without OA).

The challenging surgical treatment of closed distal humerus fractures in elderly and octogenarian patients: radiographic and functional outcomes with a minimum follow-up of 24 months. Arch Orthop Trauma Surg 2017; 137:1371-1383. [PMID: 28752182 DOI: 10.1007/s00402-017-2762-3] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2017] [Indexed: 01/28/2023]
Abstract
INTRODUCTION The main purpose of this retrospective, non-randomized, case series study was to evaluate the clinical and radiographic outcomes of distal humerus fractures (DHFs) in a consecutive series of elderly patients operatively treated by two surgeons, and second, to identify proper indications for two elderly age ranges and two fracture pattern groups. MATERIALS AND METHODS From January 2009 to June 2014, 51 patients (pts) underwent open reduction and internal fixation (ORIF) using the locking compression plate (LCP) distal humerus plate (DHP) system at our institution. Medical records and radiographs were retrospectively assessed. Patients were divided into 3 groups according to gender, age (pts <85 years, pts ≥85 years) and AO classification (13-B1-B2-C1-C2 or 13-C3). All subjects completed MEPS, Quick-DASH and SF-36 PCS/MCS scores at final follow-up, and statistical analysis was performed. RESULTS 36 patients (20 women, 16 men), mean age 80.3 years, with AO type 13-B and 13-C DHFs were included with a mean follow-up of 56 months (range 24-92). The most common mechanism of trauma was a fall from ground level (55.6%). The mean MEPS was 78.9 points, Quick-DASH 28.4, SF-36 PCS 48.3 and MCS 48.9. There was statistically significant evidence that having a 13-C3 fracture leads to worse results in MEPS, Quick-DASH and SF-36. The female gender correlates with worse results in SF-36. The patients ≥85 years had a worse prognosis according to Quick-DASH and SF-36, while the AO 13-C3 pattern obtained the worst ROM outcomes versus AO 13 B1-B2-C1-C2 (normal ROM 0°-140°): mean ROM 24°-114° vs 10°-130°, mean flexion deficit 26° vs 10°, mean extension deficit 24° vs 10°, respectively). Complications were presents in 36.1% of patients, overall belonging to the AO type 13-C fracture pattern and to the group ≥85 years. CONCLUSION These study data seem to confirm our hypothesis that plate fixation for DHFs guarantees adequate fracture osteosynthesis and satisfactory functional outcomes at medium to long-term follow-up, not only in elderly patients, but also in octogenarian osteoporotic patients (≥85 years) with 13-C1 and 13-C2 fracture patterns, while an alternative solution should be considered for type C3 fractures, even in a primary trauma setting.

Radiographic and functional outcomes after displaced intra-articular calcaneal fractures: a comparative cohort study among the traditional open technique (ORIF) and percutaneous surgical procedures (PS). J Orthop Surg Res 2016; 11:92. [PMID: 27550340 PMCID: PMC4994228 DOI: 10.1186/s13018-016-0426-6] [Citation(s) in RCA: 36] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2016] [Accepted: 08/10/2016] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Open reduction with internal fixation (ORIF) and percutaneous surgery (PS) are the most common surgical procedures for the treatment of displaced intra-articular calcaneal fractures. The purpose of this retrospective study was to compare the clinical and radiological results of these techniques and to verify the prognostic value of the radiographic measurement tools proposed in the literature. METHODS A consecutive series of 104 calcaneal fractures was included in this analysis. Essex-Lopresti and Sanders classifications were used to evaluate the injuries, and their prognostic correlation was tested. Böhler's angle was measured pre- and postoperatively and evaluated as radiological outcome. Clinical outcomes were evaluated using the American Orthopaedic Foot and Ankle Society hindfoot scale (AOFAS), Maryland Foot Scale (MFS), 17-Foot Function Index (FFI), Short Form-36 (PCS), and a 10-point visual analogue scale (VAS). RESULTS A total of 87 fractures (5 bilateral), 54 in males and 28 in females, were evaluated with a mean follow-up of 77.0 months. Overall mean age was 51.6 years old. The most frequent cause of trauma was a fall from a height. According to Essex-Lopresti, there were 58 joint depression fractures, 26 tongue, and 3 comminute. According to Sanders: 37 type II, 31 type III, and 19 type IV. Patients were divided into three groups according to surgical treatment: 19 in the ORIF group, 35 in the PS Screw group, and 33 in PS K-wire group. The ORIF group obtained significantly better results (82 AOFAS, 86 MFS, 19.6 FFI, 46.2 PCS, 8 VAS) with respect to the PS K-wire group (74 AOFAS, 76 MSF, 26.4 FFI, 40.8 PCS, 6 VAS). The PS Screw group obtained intermediate results (79 AOFAS, 82 MFS, 22.4 FFI, 41.6 PCS, 7 VAS). The restoration of the Böhler's angle was achieved most frequently (p = 0.02) in the ORIF group, without better clinical results. CONCLUSION The results were best in the ORIF group, despite its risk of complications, inferior in the PS Screw group, however without statistical significance (p > 0.05), and worse in the PS K-wire group. Finally, our data confirmed the prognostic correlation between the two radiographic classifications used and the clinical outcomes.

Abstract
The aim of the present longitudinal prospective study was to evaluate the clinical, functional, and radiologic outcomes and patient satisfaction of those who had undergone minimally invasive surgery (MIS) for tibiotalocalcaneal arthrodesis with an intramedullary nail. The 28 patients, who had consecutively undergone surgery with the MIS technique, were evaluated clinically and radiographically at 1, 2, 3, and 6 months after surgery and at last follow-up examination. For the clinical evaluation, the American Orthopaedic Foot and Ankle Society scale and visual analog scale for the foot and ankle were used in the preoperative and final follow-up examinations. The patients rated their satisfaction on a scale from 0 to 10. The mean score obtained with the American Orthopaedic Foot and Ankle Society scale was 68.28 ± 5.02 (range 58 to 74) points and with the visual analog scale for the foot and ankle was 70.76 ± 7.72 (range 58 to 82) points, with a mean follow-up of 25.07 ± 6.32 (range 6 to 40) months. The clinical improvement was statistically significant with both types of evaluation (p ≤ .05), comparing the preoperative and follow-up periods. Fusion was achieved in all patients, with a mean fusion time of 14.85 ± 4.12 (range 8 to 56) weeks. The alignment of the ankle and foot was optimal in 27 of 28 patients (96.42%), and patient satisfaction was rated as 6.71 ± 1.37 (range 5 to 10) points. Finally, the use of MIS for tibiotalocalcaneal arthrodesis with intramedullary nail results in fusion of the articulation with a low complication rate.

Abstract
BACKGROUND AND AIM OF THE WORK the treatment of acute type III acromio-clavicular Rockwood dislocations is still a matter of discussion in orthopaedic surgery. The purpose of this study, retrospective and comparative, is to evaluate the long-term results of two different surgical techniques of temporary stabilization using K-wires with and without tension band wiring. METHODS one hundred patients, treated from January 2007 and November 2010, were subdivided into two groups according to the surgical method used. They were clinically and radiographically assessed, and the results were compared with those present in the literature. RESULTS the patients were clinically and radiologically evaluated with a mean follow-up of 44.7 months (range 25-60 months). According to the Constant Score, the positive results were 87.4% in group A and 90.2% in group B, without significant statistical difference (p>0.05). However, there were numerous complications, especially metal-work mobilization. CONCLUSIONS the results that we have obtained, in part disappointing on the short-term, but positive overall and in line with the literature at long-term follow-up, do not clarify which of the two techniques is superior.

Heterotopic ossification following hip arthroplasty: a comparative radiographic study about its development with the use of three different kinds of implants. J Orthop Surg Res 2015; 10:176. [PMID: 26567916 PMCID: PMC4644335 DOI: 10.1186/s13018-015-0317-2] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2015] [Accepted: 11/08/2015] [Indexed: 12/27/2022] Open
Abstract
Background Our purpose was to record the incidence of heterotopic ossification (HO) following hip replacement by different variables to identify patient groups that are likely to develop HO in the absence of a prophylactic protocol. Methods Radiographically, we studied 651 patients having undergone hip joint replacement, evaluating three kinds of implants: ceramic-ceramic-coupled total hip replacement (THR), TriboFit® with polycarbonate urethane-ceramic coupling and endoprosthesis. Each patient was analysed for HO development by age, gender, diagnosis, presence of previous ossifications, surgical approach and kind of implant. Within the population that developed HO, data were assessed for correlation with severity of ossification graded according to Brooker classification. Results The overall incidence of HOs was 59.91 %. The factors increasing their incidence in the univariate analysis were as follows: lower age of the patients with HO (mean 77.6 years, p = 0.0018) than those subjects who did not develop HO (mean 80.2 years); male gender (64.4 %, p = 0.1011); diagnosis of coxarthrosis (72.7 %, p = 0.0001) compared to femur neck fracture (55.9 %, p = 0.0001); presence of previous HO (76.2 %, p = 0.0260); lateral approach (65.5 %) as opposed to anterior-lateral approach (55.6 %, p = 0.0163); and ceramic-ceramic THR (68.1 %) and TriboFit® (67.0 %) compared to endoprosthesis (51.3 %, p = 0.0001). During multivariate analysis, the presence of HO after previous hip surgery (p = 0.0324) and the kind of implant (p = 0.0004) showed to be independent risk factors for the development of HO. Analysing the population that developed HO, we found that the severity of ossification by Brooker classification was influenced by gender (p = 0.0478) and kind of implant (p = 0.0093). Conclusions In agreement with the literature, our radiographic study confirms the following risk factors of HO development in absence of any prophylactic treatment: male gender, diagnosis of coxarthrosis compared to femur neck fracture, previous HO, surgical approach and kind of implant. In particular, Hardinge-Bauer and Watson-Jones surgical approaches, characterized by a wide exposure of the coxofemoral joint, and ceramic-ceramic THR and TriboFit® implants significantly increase the development of HO.

Comparison of percutaneous intramedullary Kirschner wire and interfragmentary screw fixation of displaced extra-articular metacarpal fractures. ACTA BIO-MEDICA : ATENEI PARMENSIS 2014; 85:252-264.

Abstract
BACKGROUND AND AIM OF THE WORK the management of the displaced extra-articular metacarpal fractures is still a subject of debate in the literature. The purposes of this study were to report the outcomes of unstable extra-articular metacarpal fractures treated by using intramedullary Kirschner wires or inter-fragmentary screws and to determinate which techniques provide better clinical and radiographic results. METHODS we retrospectively reviewed a series of 49 consecutive patients operated for 53 closed, unstable metacarpal fractures. The fractures were divided into two groups, according to the fixation method used: the percutaneous intramedullary K-wire fixation group and the interfragmentary screw fixation group. The injuries were classified on the basis of fracture level and type. Assessment of patients was carried out according to the Mayo Wrist and Dash Scoring systems. Finally, radiographic and clinical outcomes of both groups were assessed and compared. RESULTS there were no significant differences between the two groups related to follow-up, hospitalization days, operating time, and Mayo Wrist and Dash Scores. Bone union was achieved within 6 weeks in all patients. Nine cases of malunion were found, with a mean angular deformity of 8.33° (range, 5°-15°), of which 8 were patients treated with K-wires (mean 8.125°) and 1 with screws (10°). CONCLUSION our results indicate that both procedures are effective in the treatment of displaced extra-articular metacarpal fractures. However, we believe K-wires represent the gold standard of treatment for displaced fractures of the metacarpal neck. Instead, screws are more effective for spiroid shaft fractures, while displaced fractures of the base may be treated with either screws or wires.

Nailing treatment in bone transport complications. Strategies Trauma Limb Reconstr 2014; 9:89-96.

Abstract
A series of cases of reamed intramedullary nailings carried out after complications in regenerated bone and docking site had occurred in bone transport is presented here. Nine patients (femur = 5; tibia = 4) had treatment with resection after open fractures or infection and underwent bone transport. The mean length of regenerated bone was 9.5 cm (range 6–18 cm). After bone transport, the fixator remained in place for a mean period of 12.8 months (range 8–24 months). In six cases (femur 4; tibia 2), the thickness of the cortical wall of the regenerate column was insufficient, and in two of these, there was, in addition, nonunion of the docking site. In the two tibial cases, nailing was carried out shortly after the fixator had been removed and after refracture of the regenerated bone had occurred due to insufficient cortical thickness. In one femur, nailing was carried out for nonunion of the docking site. Follow-up involved clinical and X-ray checks. The mean follow-up was 3.9 years (range 2–6 years). In all cases, union and with complete corticalization of the regenerate column was observed at an average 6 months after nailing (range 4–11 months). Infection occurred in one tibia 4 months after nailing. The infection was treated with antibiotics, and the nail was subsequently removed. We conclude that nailing is a potential solution for regenerated bone and docking site problems but, if used after prolonged periods of external fixation, may necessitate antibiotic therapy for at least 10 days after the fixator has been removed.

Treatment of proximal humeral fractures with reverse shoulder arthroplasty in elderly patients. Musculoskelet Surg 2014; 99:39-44.

Abstract
BACKGROUND Proximal humeral fractures in four or even only three parts, with metaphyseal hinge distances of <8 mm, represent a serious and widely debated problem. Reduction is complex and plating is often instable, especially in elderly patients. Failures, sometimes involving necrosis of the head, are frequent. Hemiarthroplasty has long been used for 3- or 4-part complex fractures, even in young patients, although often with sub-optimal results, due to reabsorption of tuberosities. This complication has partly been overcome with reverse shoulder prostheses which, although more invasive than partial ones, may lead to less disappointing results, even in cases of reabsorption of tuberosities. We have data on a homogeneous series of patients treated with reverse shoulder arthroplasty for proximal fractures, with a maximum follow-up of 10 years. The aim of this study was mainly to identify which cases can be selected for effective treatment and which technical aspects are best to adopt. MATERIALS AND METHODS There were 33 patients in this study, mean age 76.6 years (range 54-85). Fractures were classified according to Neer. Surgery was undertaken on average 4.4 days after trauma. The deltopectoral approach was used. Sutures were hooked over the major and lesser tubercles for later reduction and fixation after the prosthesis had been applied. This passage was sometimes not possible in cases of serious degeneration of the rotator cuff. One day after surgery, a shoulder brace providing an abducted angle of 15° was applied for 30 days. Patients were re-assessed with DASH and Constant scores (CS), and the ratio between healthy and operated shoulders was calculated. Physical examination was followed by X-rays, mainly to evaluate and classify any infraglenoid scapular notching according to Nerot. RESULTS Mean follow-up was 42.3 months (range 10-121). According to the CS, mean pain was 12.6/15 (range 3-15/15), activities of daily living 16.3/20 (range 8-20/20), ROM 21.8 (range 8-32/40) and power 5.4/25 (range 2-12/25). Total mean CS was 56.4 (range 23-80/100). The mean DASH score was 49.7 (range 32-90). The ratio of the CS parameters between opposite and operated shoulders was on average 72.8 % (range 28-90 %). Long-term complications were eight cases of scapular notching (24.2 %) of which four of grade 2 (12.1 %) and four of grade 1 (12.1 %). CONCLUSIONS Total reverse prostheses are more invasive because they also compromise the glenoid surface of the scapula, but they do offer good stability, even in cases of damage to the rotator cuff. Reverse prostheses have great advantages as regards to ROM, allowing functional recovery, which is good in cases with re-insertion of tuberosities, and acceptable in cases when tuberosities are not re-inserted or resorbed. In our cases, the first 3 reverse prostheses lasted 10, 8.3 and 7.3 years, and we believe that they will become increasingly long-lived, so that applying them in cases of complex fractures becomes more feasible. We prefer the deltopectoral approach because it can reduce and stabilize possible intra-operative diaphyseal fractures. Possible scapular notching must be foreseen when inserting the glenosphere. We had eight cases (24.2 %), of which four were Nerot grade 1 and four were grade 2. Applying the Kirschner wire in an infero-anterior position allows the glenosphere to be lowered with a tilt of 10°. Reverse prostheses are suitable for 3- or 4-part complex proximal humeral fractures in patients over 65. Prolonged physiokinesitherapy is essential.

Abstract
BACKGROUND AND AIM OF THE WORK Currently, open reduction and internal plate-screw fixation is generally accepted as the gold standard treatment of diaphyseal forearm fractures. The purpose of this retrospective study was to evaluate the clinical and radiographic outcomes of open reduction and internal fixation by using the Locking Compression Plate (LCP) implant system of radial, ulnar or combined shaft fractures of a skeletally mature patients group treated at our institution. METHODS We examined 47 patients, 44 men and 3 women, mean age 35 years (range 14-74) operated for diaphyseal fractures of the forearm. Overall 64 segments were treated: 32 ulnar and 32 radial. All patients received 3.5-mm titanium LCPs (Locking Compression Plates) with "combi-holes". Follow-ups included standard X-rays and clinical assessment according to Anderson's criteria and the DASH questionnaire. RESULTS Mean follow-up was 11 months (range 6-39). The number of the patients who achieved complete consolidation was 43 with a union rate of 91.5%. They showed 37 excellent results and 6 satisfactory results according to Anderson criteria, while non-union occurred in 4 out of 64 segments (2 ulnar and 2 radial) with a non-union rate per patient of 8,5%. The mean score of the DASH scale was 13.5 (range 0-46.7). CONCLUSIONS Our data show that internal plating gives good functional outcomes in the treatment of forearm diaphyseal fractures, as long as the surgical technique is perfect and carried out by expert surgeons. However, further research is desirable to better identify fracture types for which LCPs should be used.

Minimally invasive plate osteosynthesis in type B fibular fractures versus open surgery. Musculoskelet Surg 2013; 97:229-235. [PMID: 23900920 DOI: 10.1007/s12306-013-0292-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2012] [Accepted: 07/17/2013] [Indexed: 06/02/2023]
Abstract
BACKGROUND In traumatology, the search for better surgical access points has led to the increased use of the minimally invasive plate osteosynthesis (MIPO) technique. There are few studies on the treatment of distal fibular fractures with MIPO. Locking compression plates (LCP) for distal fibular fractures is generally applied after open reduction, but may involve complications to the surgical wound. In this study, we compared two groups of patients receiving either ORIF or MIPO, in order to analyse the advantages and disadvantages of the two techniques. MATERIALS AND METHODS Two homogeneous groups of patients (18 + 18) received LCP for distal fractures of the fibula, type B, according to AO. Group A patients underwent open surgery, whereas Group B patients received plates applied with the MIPO technique. Both groups were examined physically and radiographically 1 and 3 months after the two types of procedure and then 1 year later, with functional assessment according to Olerud and Molander. RESULTS ROM Group A: 5° reduction in tibiotarsal extension in 8 patients and 5° in supination in 1 patient; Group B: 5° reduction in extension in 7 cases. Mean healing time: 3 months (range 2-4) in Group A and 2.9 (range 2-4) in Group B. Dehiscence of the surgical wound was observed in five Group A patients, but none in Group B. Functional assessment according to Olerud and Molander was 87.4 points in Group A (range 80-100) and 95.6 in Group B (range 82-100). CONCLUSIONS We believe that the MIPO technique for distal fractures of the fibula should be used more often, especially if soft tissue is in a critical condition. Healing times should be reduced in the more complex cases. It is important that the learning curve should be improved, to minimize exposure to radioscopy and possible damage to the superficial fibular nerve.

In vitro response of osteoarthritic chondrocytes and fibroblast-like synoviocytes to a 500-730 kDa hyaluronan amide derivative. J Biomed Mater Res B Appl Biomater 2012; 100:2073-81. [PMID: 22865740 DOI: 10.1002/jbm.b.32771] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2011] [Revised: 06/07/2012] [Accepted: 06/12/2012] [Indexed: 12/12/2022]
Abstract
The aim of this study was to compare the effects of native hyaluronan (HA) with that of its hexadecylamide derivative (HYADD) on proliferation of fibroblast-like synoviocytes (FLS) and chondrocytes. The production of inflammatory and anti-inflammatory cytokines was also analyzed in FLS cultures. The proliferation of osteoarthritis (OA) chondrocytes was enhanced when cells were treated with 0.5-1.5 mg mL(-1) of HA or HYADD®4-G. This effect was completely suppressed by the anti-CD44 antibody. At 0.5 to 1 mg mL(-1) , HA and HYADD®4-G did not influence the proliferation of normal or pathological FLS; however, at the higher concentration (1.5 mg mL(-1) ), HYADD®4-G did significantly inhibit cell proliferation. As to effects on inflammation, a significant increase in the expression of the IL-10 gene was observed when FLS were pretreated with tumor necrosis factor alpha and then cultured in the presence of 0.5 mg mL(-1) HYADD® 4-G or HA. The effects of HA derivatives on FLS proliferation and production of anti-inflammatory cytokines indicate that they may be of therapeutic benefit in OA. The longer residence time in the joint cavity, the increased viscoelasticity, and the anti-inflammatory potential of HYADD®4-G make it a better candidate than native HA for OA therapy.

Abstract
This study examines 32 patients operated for radial head fractures, mean age 48.7 years (range 26-76 years), Mason type II in 25 cases and Mason type III with 3 main fragments in 7 cases. Fractures were surgically reduced and fixed with Herbert's (12 cases) or Osteomed (20 cases) cannulated screws. The latter have a head that is <1 mm high and are only threaded distally. Both types of screw provide compression across the fracture. In Mason type II cases, the mean MEPS score was 98.4 and the DASH score 6.8. In Mason type III cases, MEPS was 99.3 and DASH 9.5. We believe that fixation can be carried out with screws alone, which are less invasive, and that the screw heads should preferably be completely buried, to avoid stiffness in prono-supination. In addition, suturing of the annular ligament and the joint capsule is made easier by the reduced invasiveness of screws. Screw treatment is effective in non-comminuted fractures of the radial head.

Abstract
Long-term results of percutaneous treatment for 36 scaphoid fractures, types B1 and B2 according to Herbert, are reported. Outcomes were satisfactory in nearly all cases. In three patients, the screw was too long and had to be removed, and pseudoarthrosis developed in one patient. Consolidation was observed after 6-8 weeks, less than literature reports for immobilization with casts. The percutaneous approach is particularly suitable for younger patients who work or play sports.

Abstract
In recent years, plate osteosynthesis with angular stable implants is frequently used for severely displaced three- and four-part proximal humeral fractures. The aim of this study is to evaluate early results of these fractures treated with insertion of LCP or Philos plates. We present results in 30 cases of proximal humeral fractures, 17 with 3 parts according to Neer and 13 with 4 parts, treated with Locking Compression Plates (LCP, 14 cases) and Philos plates (16) by the deltopectoral approach. Patients were checked with standard X-rays and clinical evaluation, according to the Constant-Murley shoulder score, Individual Constant score and Relative Constant score. Mean follow-up time was 21 months (range 6-42 months). The mean Constant-Murley shoulder scores were Pain 10.6 (3-15), Activities of Daily Living 15.3 (2-20), Range of Motion 26.8 (12-40) and Power 10.3 (3-25) and Total 63 (25-97). The Individual Constant score was 68.6% (27-98%) and the Relative Constant score 85.4% (36-130%). Fractures in 3 parts (of the surgical or anatomic humeral neck and major tubercle) had a mean Constant score of 69.1 (17 cases), but this fell to 55 (13 cases) in those in 4 parts (neck, major and lesser tubercles). Late necrosis of the humeral head occurred in two cases, both with 4-part breaks. We thus believe that 3-part fractures, in which both reduction and stable osteosynthesis are easier, show favourable prognosis and should be clearly distinguished from 4-part ones during assessments. The deltopectoral approach offers good exposure and is especially recommended in 4-part fractures, also because it provides a good view of the lesser tubercle. The osteosynthesis must be stable if early mobilisation of the shoulder and proper recovery of range of motion are to be achieved. As well as reduction and stabilisation of the tubercles, it is also important to restore the neck/shaft angle and stabilise it with oblique screws fitting the plate to avoid varus malposition.

Abstract
We present the results of treatment of 100 patients (72 men, 28 women) by the Ilizarov method of bone transport using circular (55) and monolateral external fixators (45). A total of 26 femurs (18 monolateral, 8 circular) and 74 tibias (49 circular, 25 monolateral) was examined. There were no significant differences between the circular fixator and the monolateral fixator with regard to treatment time, complications in the treated bone segments or compliance with the presence of the fixator. The main complications (pseudoarthrosis at bone contact points after transport, insufficient ossification of lengthened bone, knee stiffness) were resolved with further treatment for all patients with the exception of one case which continued with repeated infections. The circular fixator allows for deformity corrections during bone transport but the monolateral fixator is tolerated better by patients, especially in those with femoral defects.

Abstract
This paper analyses 80 cases of displaced proximal humerus fractures, with two or three fragments, treated by PHN nailing. The hold of the spiral blade was effective, and is particularly recommended for fractures with two fragments according to Neer's classification. The results, analysed with Constant's score and radiographic checkups, were satisfactory. Nearly all our patients (76 out of 80) had a mean age of 75 years and a total Constant score of 78.48. Only four (mean age 42.5 years) had a Constant score of 86. Shoulder articulation was good and only a few complications occurred.

Abstract
The Authors analyse the results of intramedullary nailing in a group of 101 femoral shaft fractures. Used nails: Universal Synthes (62 cases), Russel-Taylor (14), Gamma long (10), uncannulated femoral nail (9), cannulated femoral nail (4) and proximal femoral nail (2). Stabilisation of the femoral shaft fracture was possible using a reamed technique in 91 cases, unreamed in 10. All nails were locked. Dynamisation was performed in 35 cases and was not in 66. The fracture heal was faster with the reaming and dynamisation technique. Ten fractures were open (5 Gustilo I, 5 Gustilo II) and stabilisation with Universal Synthes nail (8 cases), Russel-Taylor nail (1) and Gamma long nail (1) was performed. No infection was detected. Lung embolism (6) and deep vein thrombosis (3) occurred only in the case of reamed nails. All results confirm the locking nail system as the best treatment in the shaft fractures, especially with new-generation nails.

Abstract
A total of 3 malignant neoplasms of the tibia are presented: 1 is a mesenchymal chondrosarcoma of the tibial pylon (male aged 14 years), and 2 are cases of squamous skin carcinoma of the leg with tibial infiltration (1 male and 1 female aged 32 and 64 years, respectively). The resections carried out (16.5 cm on the average) were treated by bone transport. Simple transport was used in the first patient, double in the other two. At the end of transport a second surgical stage involving astragalotibial arthrodesis was performed in the first case, and revision of the junction site of bone segments transported with application of autoplastic bone grafts was performed in the other two. The regenerate obtained was slowly corticalized in the first patient, submitted to various cycles of chemotherapy during the course of distraction. In the other two cases, which were not treated by chemotherapy during distraction, corticalization occurred over a shorter amount of time. Follow-up was obtained after 10 years in the first case, and after 2 years in the other 2 patients. There was no long-term recurrence.

Abstract
The results of the treatment of 18 cases of nonunion of the tibial pylon using the Ilizarov method are presented. The level of the nonunion was divided into A (epiphyseal, 2 cases), B (from 1 to 4 cm from the joint rima, 7 cases), and C (from 4 to 7 cm from the rima, 9 cases). Nonunion was atrophic in 12 cases, hypertrophic in 2, and infected in 4. Bone grafts were applied in 8 atrophic cases, while bone resection with transport or resection-shortening was performed in the 4 cases with infection, or resection-shortening and then lengthening in 2 cases. Consolidation was always achieved. Range of movement was very compromised in 9 cases, of which 5 initially presented with joint fracture, while another 4 had had septic complications after fracture.

Abstract
The authors present a clinical-radiographic study on two groups of patients affected with aseptic nonunion and delays in consolidation of the tibia treated by intramedullary nailing (24 cases) and Ilizarov method (29 cases). Nailing was locked in 12 cases and associated with resection of the fibula in 15 (in 8 locked nailing). Autoplastic bone grafts were applied in 3 cases of atrophic nonunion. The Ilizarov method was used with different procedures: standard assembly in 23 patients, of which 6 with the application of autoplastic grafts for atrophic nonunion. En bloc resection of the atrophic nonunion was carried out in 6 patients followed by removal (4 cases) or lengthening (2 cases). Parafocal osteotomy according to Paltrinieri was reserved for closed hypertrophic nonunion with severe varus and procurvatum. The data for this study allow the authors to conclude that intramedullary nailing is preferable in delays in consolidation and in hypertrophic nonunion without angular defects or hypometria, while the Ilizarov method is more indicated in atrophic nonunions and in hypertrophic nonunions with hypometria and angular defects.

Abstract
The case presented is that of a man aged 54 years, with hypertrophic pseudarthrosis shortening by 3 cm and a femoral mechanical axis measuring 13 degrees varus. Parafocal osteotomy according to Paltrinieri was carried out with the aim of correcting the varus femur, the shortening and, secondarily, of obtaining recovery from the pseudarthrosis. Osteosynthesis was achieved by the Ilizarov apparatus. Axial correction and lengthening were obtained after 33 days. The fixator was removed after 5 months and 10 days, during which the nonunion appeared healed.

Abstract
Ruptures of the long head of the biceps brachii are mostly of degenerative nature, secondary to subacromial impingement and morphological changes in the bicipital groove. Clinical findings are typical. Treatment is controversial, as it may either be surgical or non-surgical. The authors considered only those cases in which tendinous rupture was the first manifestation of pathology caused by wearing, with typical deformity of the profile of the arm. The favorable results of surgical treatment in 14 patients aged from 38 to 70 years, followed-up after an average of 10.9 years, are reported. Among surgical methods used, tenodesis at the bicipital groove currently constitutes the method of choice.

Abstract
Two cases of monolateral voluntary hip dislocation in Down's syndrome are reported. No surgical procedure was permitted by the family in either case, thus showing the natural evolution of the joint morphology. In the case observed a year after the onset of hip dislocation CT Scan already showed an initial smoothing of the posterior acetabular wall. In the other case, after a 9 year follow-up, the voluntary hip dislocation was followed by progressive subluxation and fixed dislocation at the end. This suggests that only early surgical treatment can prevent this outcome.

Abstract
The authors report 3 cases of rare spondylocostal dysplasia (Jarcho-Levin syndrome) associated with multiple visceral anomalies (V.A.C.TE.R.L. syndrome). The difficulty encountered in treating the disease because of the complexity and multiplicity of the visceral anomalies, and the extent and type of associated vertebral deformities is emphasized. The cases described revealed a moderate amount of progression, and were able to be treated non-surgically. It is also emphasized that even when there is moderate scoliosis associated costal deformities may cause anti-cosmetic thoracic gibbosity.
