Aim. In the context of total knee arthroplasty (TKA), trauma with perigenicular fracture fixation or oncological surgical treatment, soft tissue defects can expose critical structures such as the extensor apparatus, the knee joint, bone or implants. This work compares soft tissue reconstruction (STR) between a classical pedicled gastrocnemius (GC) muscle flap and a pedicled chimeric sural artery perforator (SAP) musculocutaneous GC flap in complex orthoplastic scenarios. Method. A retrospective study was conducted on prospectively maintained databases in three University Hospitals from January 2016 to February 2021 after orthopaedic, traumatological or oncological treatment. All patients with a perigenicular soft tissue defect and implant-associated infection were included undergoing STR either with a pedicled GC flap or with a pedicled chimeric SAP-GC flap. The outcome analysis included successful STR and flap related complications. The surgical timing, preoperative planning and surgical technique are discussed together with the postoperative rehabilitation protocol. Results. 43 patients were included (22 GC muscle flaps, 21 SAP-GC musculocutaneous flaps). The GC and SAP-GC patient group were comparable in terms of age, comorbidities, defect size and follow-up. The incidence of flap related complications was comparable among the two groups. Specifically, in the SAP-GC group 1
Aims. Tibial tubercle osteotomy (TTO) facilitates surgical exposure and protects the extensor mechanism during revision total knee arthroplasty (rTKA). The purpose of this study was to determine the rates of bony union, complications, and reoperations following TTO during rTKA, to assess the functional outcomes of rTKA with TTO at two years’ minimum follow-up, and to identify the risk factors of failure. Methods. Between January 2010 and September 2020, 695 rTKAs were performed and data were entered into a prospective database. Inclusion criteria were rTKAs with concomitant TTO, without extensor mechanism allograft, and a minimum of two years’ follow-up. A total of 135 rTKAs were included, with a mean age of 65 years (SD 9.0) and a mean BMI of 29.8 kg/m. 2. (SD 5.7). The most frequent indications for revision were infection (50%; 68/135), aseptic loosening (25%; 34/135), and stiffness (13%; 18/135). Patients had standardized follow-up at six weeks, three months, six months, and annually thereafter. Complications and revisions were evaluated at the last follow-up. Functional outcomes were assessed using the Knee Society Score (KSS) and range of motion. Results. The mean follow-up was 51 months (SD 26; 24 to 121). Bony union was confirmed in 95% of patients (128/135) at a mean of 3.4 months (SD 2.7). The complication rate was 15% (20/135), consisting of nine tibial tubercle fracture displacements (6.7%), seven nonunions (5%), two delayed unions, one tibial fracture, and one
Background. Surgical wound closure is not the surgeon”s favorite part of the total knee arthroplasty (TKA) surgery however it has vital rule in the success of surgery. Knee arthoplasty wounds are known to be more prone to infection, breakdown or delayed healing compared to hip arthroplasty wounds, and this might be explained by the increased tensile force applied on the wound with knee movement. This effect is magnified by the enhanced recovery protocols which aim to obtain high early range of movement. Most of the literature concluded that there is no difference between different closure methods. Objectives. We conducted an independent study comparing the complication rate associated with using barbed suture (Quill-Ethicon), Vicryl Rapide (polyglactins910-Ethicon) and skin staples for wound closure following TKA. Study Design & Methods. Retrospective study where the study group included all the patients admitted to our unit for elective primary knee arthroplasty in 2015, we excluded patients admitted for partial knee arthroplasty, revision knee arthroplasty or arthroplasty for treatment of acute trauma due to the relatively higher complication rates. All the patients notes were reviewed to identify wound related problems such as
Introduction. We describe a novel single incision approach and its safety in the largest reported series of Lisfranc injuries to date. Via separate subcutaneous windows it is possible to access the medial three rays of the foot for bridge plating, without the concern of narrow skin bridges between multiple incisions. Methods. A retrospective review identified all 150 patients who underwent a Lisfranc ORIF via the modified dorsal approach at the Royal Melbourne Hospital between January 2011 and June 2016. All patients were operated by a single surgeon. Removal of metalwork (ROM) was routinely undertaken at six months post-operatively via the same incision. Medical recored were reviewed to record patient demographics, mechanism of injury and surgical details. Outpatient notes were reviewed to identify wound-related complications including; delayed wound healing, superficial infection,
Aims. To evaluate the perioperative complications associated with total en bloc spondylectomy (TES) in patients with spinal tumours, based on the extent and level of tumour resection. Methods. In total, 307 patients who underwent TES in a single centre were reviewed retrospectively. There were 164 male and 143 female patients with a mean age at the time of surgery of 52.9 years (SD 13.3). A total of 225 patients were operated on for spinal metastases, 34 for a malignant primary tumour, 41 for an aggressive benign tumour, and seven with a primary of unknown origin. The main lesion was located in the thoracic spine in 213, and in the lumbar spine in 94 patients. There were 97 patients who underwent TES for more than two consecutive vertebrae. Results. Major and minor perioperative complications were observed in 122 (39.7%) and 84 (27.4%) patients respectively. The breakdown of complications was as follows: bleeding more than 2,000 ml in 60 (19.5%) patients, hardware failure in 82 (26.7%), neurological in 46 (15.0%), surgical site infection in 23 (7.5%),
Introduction. Cerament, a bioresorbable hydroxyapatite and calcium sulfate cement, is known to be used as a bone-graft substitute in traumatic bone defect cases. However, its use in open fractures has not previously been studied. Materials and Methods. Retrospective, single-centre review of cases between November 2016 and February 2021. Open fractures were categorised according to the Orthopaedic Trauma Society classification (OTS). Cases were assessed for union, time to union, and associated post-operative complications. Results. Twenty-four patients were identified. Fifteen cases were classified as OTS simple open fractures, and nine cases were complex open fractures requiring soft tissue reconstruction. Four cases were lost to follow-up. Four cases had limited follow-up beyond 6 months but showed evidence of progressive radiographic union. Of the remaining 16 cases, eight cases (50%) went on to union with a mean time to union of 6.7 months (5 to 12 months). Persistent non-union remained in six cases (38%). Two cases required return to theatre due to an infected skin graft and
Introduction. Amputation or disarticulation is a reliable option for management of severe foot deformities and limb-length discrepancies, the surgical restoration of which are unpredictable or unfavourable. Of the various surgeries involving foot ablation, Syme's amputation is preferred for congenital deformities as it provides a growing, weight bearing stump with proprioception and cushioning. Materials and Methods. We reviewed data of all children who underwent Syme's amputation over the past 13 years at our institution. Surgical technique followed the same principles for Syme's but varied with surgeons. Results. Ten boys and ten girls, with an average age of 18 months and average follow up of 70 months were included in the study. The most common indication was fibular hemimelia. Wound complications were reported in three children, phantom pain in one, heel pad migration in two. None had
This large UK multicentre study evaluates clinical outcomes and identifies factors associated with local complication following PFR for non-oncological conditions. 132 patients across four UK centres underwent PFR from 01/08/2004-28/03/2023 with median follow-up of 1.9 (Q10.5-Q34.2) years. 75 (56.8%) patients were female and the mean age was 74.0 (SD 11.7) years. 103 (78%) patients had Charleston Comorbidity Index ≥3. ASA class was III or IV in 66.6%. Indications were infected revision (39, 29.5%), periprosthetic fracture (36, 27.3%), acute trauma (30, 22.7%), aseptic revision (17, 12.9%), failed trauma (nine, 6.8%) and complex primary arthroplasty (one, 0.8%). The primary outcome was the local complication rate. Secondary outcomes were systemic complications, reoperation and mortality rates. Comparisons were made with t-tests and Chi2 tests to investigate patient and surgical factors associated with local complication. Statistical significance was p<0.05. There were 37(28.0%) local complications. These were 18 (13.6%) dislocations, eight (6.1%) prosthetic joint infections, four (3.0%) haematomas, three (2.3%) superficial infections, one (0.8%)
Aim. The optimal surgical approach for patients hospitalized for moderate to severe septic bursitis is not known, and there have been no randomized trials of a one-stage compared with a two-stage (i.e., bursectomy, followed by closure in a second procedure) approach. Thus, we performed a prospective, non-blinded, randomized study of adult patients hospitalized for an open bursectomy. Method. Patients were randomized 1:1 to a one-stage vs. a two-stage surgical approach. All patients received postsurgical oral antibiotic therapy for 7 days. These are the final results of the prospective study registered at ClinicalTrials (NCT01406652). Results. Among 164 enrolled patients, 130 had bursitis of the elbow and 34 of the patella. The surgical approach used was one-stage in 79 and two-stage in 85. The two groups were balanced with regards to sex, age, causative pathogens, levels of serum inflammatory markers, co-morbidities, and cause of bursitis. Overall, there were 22 treatment failures: 8/79 (10%) in the one-stage arm and 14/85 (16%) in the two-stage arm (Pearson-χ2-test; p=0.23). Recurrent infection was caused by the same pathogen a total of 7 patients (4%), and by a different pathogen in 5 episodes (3%). The incidence of infection recurrence was not significantly different between those in the one- vs. two-stage arms (6/79 vs. 8/85; χ2-test: p=0.68). In contrast, outcomes were better in the one- vs. two-stage arm for

Introduction. Intraarticular calcaneal fractures often need open reduction and internal fixation (ORIF) with plate osteosynthesis. The wound complication is one of the common problems encountered following this and affects the outcome adversely. Our study was done to assess how far postoperative slab/cast can avert wound complications. Methods. Out of 42 patients with unilateral intraarticular calcaneal fractures, 20 were offered postoperative slab/cast and this was continued for six weeks. The remaining 22 patients were not offered any plaster. All patients were followed-up for two years. Results. The incidence of

osteogenesis followed by arthrodesis using internal fixation to
manage complex conditions of the ankle, and to present the results
of this technique. Patients and Methods. Between 2008 and 2014, distraction osteogenesis followed by arthrodesis
using internal fixation was performed in 12 patients with complex
conditions of the ankle due to trauma or infection. There were eight
men and four women: their mean age was 35 years (23 to 51) at the
time of surgery. Bone healing and functional recovery were evaluated
according to the criteria described by Paley. Function was assessed
using the ankle-hindfoot scale of the American Orthopedic Foot and
Ankle Society (AOFAS). Results. A solid fusion of the ankle and eradication of infection was
achieved in all patients. A mean lengthening of 6.1 cm (2.5 to 14)
was achieved at a mean follow-up of 25.2 months (14 to 37). The
mean external fixation index (EFI) was 42 days/cm (33.3 to 58).
The function was judged to be excellent in six patients and good
in six patients. Bone results were graded as excellent in ten patients
and good in two patients. The mean AOFAS score was 37.3 (5 to 77) preoperatively
and 75.3 (61 to 82) at the final follow-up. Minor complications,
which were treated conservatively, included pain, pin-tract infection,
loosening of wires, and midfoot stiffness. Major complications,
which were treated surgically included grade V pin-tract infection
with inflammation and osteolysis, poor consolidation of the regenerate
bone, and soft-tissue invagination. The reoperations required to
treat the major complications included the exchange of pins and
wires, bone grafting and invagination split surgery. Conclusion. The technique of distraction osteogenesis followed by arthrodesis
using internal fixation is an effective form of treatment for the
management of complex conditions of the ankle. It offers a high
rate of union, an opportunity to remove the frame early, and a reduced
EFI without infection or
Since its approval by the FDA two decades ago, Negative Pressure Wound Therapy (NPWT) has become a valuable asset in the management of open fractures with significant soft tissue damage as those seen in high velocity gunshot injuries. These lesions are often associated with grossly contaminated wounds and require a prompt and effective approach.
Open reduction and internal fixation (ORIF) of ankle fractures is associated with well known complications including
For soft tissue sarcoma patients receiving preoperative radiation therapy, wound complications are common and potentially devastating; they may result in multiple subsequent surgeries and significant patient morbidity. The purpose of this study was to assess the feasibility of intraoperative indocyanine green fluorescent angiography (ICGA) as a predictor of wound complications in resections of irradiated soft tissue sarcoma of the extremities. A consecutive series of patients of patients with soft tissue sarcoma of the extremities or pelvis who received neoadjuvant radiation and a subsequent radical resection received intraoperative ICGA with the SPY PHI device (Stryker Inc, Kalamazoo MI) at the time of closure. Three fellowship trained Orthopaedic Oncologic Surgeons were asked to prospectively predict likelihood of wound complications based on fluorescence. Retrospective analysis of fluorescence signal along multiple points of the wound length was performed and quantified. The primary endpoint was wound complication, defined as delayed wound healing or

We have treated 14 patients (15 fractures) with nonunion of an intra-articular fracture of the body of the calcaneum. The mean follow-up was six years (2 to 8.5). A total of 14 fractures (93%) had initially been treated operatively with 12 (86%) having non-anatomical reductions. Four feet (27%) had concomitant osteomyelitis. Of the nonunions, 14 (93%) went on to eventual union after an average of two reconstructive procedures. All underwent bone grafting of the nonunion. The eventual outcome was a subtalar arthrodesis in ten (67%) cases, a triple arthrodesis in four (27%) and a nonunion in one (6%). Three patients had a

Blood management protocols attempt to reduce blood loss by strategies including autologous blood donation, red cell salvage, normovolaemic haemodilution and haemostatic agents such as tranexamic acid (TXA). TXA usage in particular has become increasingly commonplace with numerous studies demonstrating a significant reduction in peri-operative blood loss and proportion of patients requiring transfusion, without increasing the risk of venous thromboembolism. Tourniquet usage has now become ubiquitous in TKA operations with reported benefits of improved visualization, shorter operative time and decreased intra-operative bleeding. However, its use is not without considerable complications including
Introduction. The purpose of the study was to assess the clinical outcomes of an algorithm for soft tissue femoral release in anterior approach (AA) total hip arthroplasty (THA). Specifically, the following were assessed in this series of patients utilizing a standardized soft tissue release sequence: 1) clinical outcomes with the Harris Hip Score (HHS); 2) re-operation rates; 3) component survivorship; and 4) complications. Methods. We retrospectively analyzed a prospectively maintained database of patients who underwent AA THA from 2014 to 2017. A total of 1000 patients were included, with minimum follow up of 2 years (range 2–5 years). The mean age was 65 years (range, 22–89), 48% were males, and the mean Body Mass Index was 34 (range, 20–52). Descriptive statistics were performed for most endpoints except for component survivorship, which was assessed with Kaplan-Meier analysis. Result. There was 95% follow-up (54 patients lost to follow-up). The HHS improved from mean 56 preoperatively (range, 34–78) to mean 88 post-operatively (range, 65–100) (p<0.01). There were three complications: one superficial
Introduction: The purpose of this study was to review the results of revision total hip replacement, using cement, done by a single surgeon in a tertiary referral centre. 164 patients underwent revision hip surgery for aseptic loosening, infection or recurrent dislocation. Methods: 95 patients had a one stage revision, 25 patients had two stage revisions and the remainder had either the stem or socket revised. 10 patients had application of a PLAD for recurrent dislocation. Structural and morselized bone grafting was carried out in patients with extensive bone loss. 46 patients had morselized impaction bone grafting to the acetabulum. The first hundred patients with revision of both components and minimum follow up of twelve months were reviewed. Patients were routinely followed up in the clinic and assessed using the Oxford Hip Score and Merle D’Abigne scores for pain, function and range of movements. Radiographs were assessed for any demarcation or loosening. Results: The mean age at surgery was 69.99 years (36ys to 95yrs). The mean follow up was 25 months (12 to 60 months). There were 5 dislocations, 2

Purpose: Multi-modal therapy remains the cornerstone of post-operative pain management following knee replacement surgery. Femoral nerve catheters and blocks have been used with success in the management of post-operative pain yet most practicing arthroplasty surgeons and anaesthesiologists are unaware of the potential complications and risks of the procedure. The purpose of this study is to report on the complications associated with these techniques following knee replacement surgery. Method: One thousand one hundred and ninety patients underwent knee replacement surgery between January 2004 and July 1, 2007 and received an indwelling continuous infusion femoral catheter for post-operative marcaine pump infusion. For the initial 469 patients (Group 1), the continuous infusion ran for 2 to 3 days. In 721 patients, the continuous infusion was discontinued 12 hours following surgery (Group 2). Results: There were 15 major complications observed in 1190 patients: 7 femoral nerve palsies (2 in Group 1, 5 in Group 2) and 8 falls (4 in each group). For the patients who had fallen in hospital, the injuries sustained were: traumatic hemarthrosis, hemarthrosis requiring arthrotomy, major
A suitable wound closure is an indispensable requirement for an uncomplicated and expedient recovery after an abdominal surgery. The closure technique will have a great impact on the healing process of the wound. Surgical complications, such as
Malnutrition is an important consideration during the perioperative period and albumin is the most common laboratory surrogate for nutritional status. The purpose of this study is to identify if preoperative serum albumin measurements are predictive of infection following arthroscopic procedures. Patients undergoing knee, shoulder or hip arthroscopy between 2006–2016 were identified in the American College of Surgeons National Surgical Quality Improvement Program database. Patients with an arthroscopic current procedural terminology code and a preoperative serum albumin measurement were included. Patients with a history of prior infection, including a non-clean wound class, pre-existing wound infection or systemic sepsis were excluded. Independent t-tests where used to compare albumin values in patients with and without the occurrence of a postoperative infection. Pre-operative albumin levels were subsequently evaluated as predictors of infection with logistic regression models. There were 31,906 patients who met the inclusion criteria. The average age was 55.7 years (standard deviation (SD) 14.62) and average BMI was 31.7 (SD 7.21). The most prevalent comorbidities were hypertension (49.2%), diabetes (18.4%) and smoking history (16.9%). The average preoperative albumin was 4.18 (SD 0.42). There were 45 cases of superficial infection (0.14%), 10 cases of
Several recent studies have shown an increased incidence of symptomatic non-unions and malunions after non-operative treatment of displaced clavicle fractures. Our multicenter randomized control trial comparing sling treatment and plate fixation shows statistically significant improvement in patient oriented outcome measures at all time points measured over one year of follow-up. Non-operative group complications included six non-unions, one symptomatic malunion and one patient with reflex sympathetic dystrophy in thirty-four patients. Complications in the operative group included one
The rate of fracture and subsequent nonunion after radiation therapy for soft-tissue sarcomas and bone tumors has been demonstrated to quite high. There is a paucity of data describing the optimal treatment for these nonunions. Free vascularized fibular grafts (FVFG) have been used successfully in the treatment of large segmental bone defects in the axial and appendicular skeleton, however, their efficacy with respect to treatment of radiated nonunions remains unclear. The purpose of the study was to assess the 1) union rate, 2) clinical outcomes, and 3) complications following FVFG for radiation-induced femoral fracture nonunions. We identified 24 patients who underwent FVFG for the treatment of radiation-induced femoral fracture nonunion between 1991 and 2015. Medical records were reviewed in order to determine oncologic diagnosis, total preoperative radiation dose, type of surgical treatment for the nonunion, clinical outcomes, and postoperative complications. There were 11 males and 13 females, with a mean age of 59 years (range, 29 – 78) and a mean follow-up duration of 61 months (range, 10 – 183 months). Three patients had a history of diabetes mellitus and three were current tobacco users at the time of FVFG. No patient was receiving chemotherapy during recovery from FVFG. Oncologic diagnoses included unspecified soft tissue sarcomas (n = 5), undifferentiated pleomorphic sarcoma (UPS) (n = 3), myxofibrosarcoma (n = 3), liposarcoma (n = 2), Ewing's sarcoma (n = 2), lymphoma (n = 2), hemangiopericytoma, leiomyosarcoma, multiple myeloma, myxoid chondrosarcoma, myxoid liposarcoma, neurofibrosarcoma, and renal cell carcinoma. Mean total radiation dose was 56.3 Gy (range, 39 – 72.5), given at a mean of 10.2 years prior to FVFG. The average FVFG length was 16.4 cm. In addition to FVFG, 13 patients underwent simultaneous autogenous iliac crest bone grafting, nine had other cancellous autografting, one received cancellous allograft, and three were treated with synthetic graft products. The FVFG was fixed as an onlay graft using lag screws in all cases, additional fixation was obtained with an intramedullary nail (n = 19), dynamic compression plate (n = 2), blade plate (n = 2), or lateral locking plate (n = 1). Nineteen (79%) fractures went on to union at a mean of 13.1 months (range, 4.8 – 28.1 months). Musculoskeletal Tumor Society scores improved from eight preoperatively to 22 at latest follow-up (p < 0.0001). Among the five fractures that failed to unite, two were converted to proximal femoral replacements (PFR), two remained stable pseudarthroses, and one was converted to a total hip arthroplasty. A 6th case did unite initially, however, subsequent failure lead to PFR. Seven patients (29%) required a second operative grafting. There were five additional complications including three infections, one
Introduction. Tibial component loosening is a frequent cause of failure in primary total knee arthroplasty (TKA). Management options include isolated tibial component revision or full component revision. A full component revision is frequently selected by surgeons who are unfamiliar with the existing implant or have a “let's just start over attitude.” This option adds morbidity versus isolated tibial exchange. While isolated tibial exchange has lower morbidity, it is technically more challenging with regard to exposure and maintaining prosthetic stability. This study was designed to compare these two reconstructive options. Methods. Patients revised for isolated aseptic tibial loosening were identified from 2012–2017. Patients with revision implants, or those revised for infection, instability, osteolysis, or femoral component loosening were excluded. 161 patients met these criteria, 85 patients had an isolated tibial revision and 76 had revision of both components despite having only a loose tibial component. Patient demographics as well as clinical and radiographic outcomes were recorded for each cohort. Results. Patient demographical information, including age, gender, and BMI were statistically similar between the two cohorts. Median follow-up was 3.5 years. Supplemental metaphyseal fixation was used in 22 patients in the isolated tibial cohort and 19 of the full revision cohort. There was a higher incidence of radiographic loosening in the full component revision cohort (10.5% vs. 6.0%; p=0.28). There were five failures requiring revision in the isolated tibial cohort, two for sepsis, one for repeat isolated tibial loosening, one for femoral aseptic loosening, and one for an extensor mechanism disruption. There were eight failures in the full component cohort, three for patellar avascular necrosis, two for sepsis, one for repeat tibial loosening, one for arthrofibrosis, and one for a postoperative
We present the outcome of 47 Souter-Strathclyde replacements of the elbow with a mean follow-up of 82 months (12 to 129). The clinical results were assessed using a condition-specific outcome measure. The mean total score (maximum 100) before the operation was 47.21 and improved to 79.92 (p <
0.001). The mean pain score (maximum 50) improved from 21.41 to 46.70 (p <
0.001) and the mean functional component of the score (maximum 30) from 11.19 to 18.65 (p <
0.001). There was negligible change in the score for the range of movement although a significant improvement in mean flexion from 124° to 136° was noted (p <
0.001). Revision surgery was required in four patients, for dislocation,
Orthopaedic surgical site infections (SSI's) prolong total hospital stays by a median of 2 weeks per patient, approximately double re-hospitalization rates, and increase healthcare costs by more than 300%. Patients with orthopaedic SSI's have significant reductions in their health-related quality of life. We performed a systematic review and meta-analysis to compare differences in outcomes between use of sutures and non-absorbable staples for closure of orthopaedic surgical wounds in adults. The primary outcomes were rates of superficial and deep SSI. Secondary outcomes included
Intro/Purpose. Lateral partial knee replacement is indicated as an alternative to total knee replacement for isolated end stage lateral compartment degenerative joint disease. The purpose of this study is to report the surgical technique and clinical results of a large series of lateral partial knee replacements from two institutions. Methods. A retrospective review identified 205 lateral unicompartmental arthroplasty procedures performed in two practices over a six-year period (Aug 2011 – June 2017). Patients indicated for surgery met specific preoperative clinical and radiographic criteria confirming lateral compartment arthritic disease with a correctable deformity, intact full-thickness medial cartilage, competent anterior cruciate ligament, and minimal disease in the patellofemoral compartment. A single cemented fixed bearing tibial component design was used in all cases specifically designed for lateral compartment anatomy. Results. The average age was 65 years old and 76% were female. Average follow-up in the lateral partials was 1.7 years (range 0.5 years to 6 years). Knee Society Scores improved from 45 (pre-op) to 88 points (post-op). Range of motion improved from 6–115o (pre-op) to 0–122 o (post-op). No knees were revised to a TKA. One knee had an additional medial partial knee placed at 1.1 years post lateral partial knee replacement for medial disease progression. Two knees required an irrigation and debridement for traumatic
Introduction. Soft-tissue balancing methods in TKA have evolved from surgeon feel to digital load-sensing tools. Such techniques allow surgeons to assess the soft-tissue envelope after bone cuts, however, these approaches are ‘after-the-fact’ and require soft-tissue release or bony re-cuts to achieve final balance. Recently, a robotic ligament tensioning device has been deployed which characterizes the soft tissue envelope through a continuous range-of-motion after just the initial tibial cut, allowing for virtual femoral resection planning to achieve a targeted gap profile throughout the range of flexion (figure-1). This study reports the first early clinical results and patient reported outcomes (PROMs) associated with this new technique and compares the outcomes with registry data. Methods. Since November 2017, 314 patients were prospectively enrolled and underwent robotic-assisted TKA using this surgical technique (mean age: 66.2 ±8.1; females: 173; BMI: 31.4±5.3). KOOS/WOMAC, UCLA, and HSS-Patient Satisfaction scores were collected pre- and post-operatively. Three, six, and twelve-month assessments were completed by 202, 141, and 63 patients, respectively, and compared to registry data from the Shared Ortech Aggregated Repository (SOAR). SOAR is a TJA PROM repository run by Ortech, an independent clinical data collection entity, and it includes data from thousands of TKAs from a diverse cross-section of participating hospitals, teaching institutions and clinics across the United States and Canada who collect outcomes data. PROMs were compared using a two-tailed t-test for non-equal variance. Results. When comparing the baseline PROM scores, robotic patients had equivalent womac knee stiffness (p=0.58) and UCLA activity scale (p=0.38) scores but slightly higher womac knee pain (p=0.002) and functional scores (p=0.014, figure-2). While all scores improved over time, the rate of improvement was generally greater at 6 months than at three months when comparing the two groups, with statistically higher six-month scores in the robotic group for all categories (p<0.001). Overall patient satisfaction in the RB cohort was 90.3%, 95.0% and 91.8% at 3M, 6M and 1Y, respectively (figure-3). Average length of hospital stay was 1.6 days (±0.8). Surgical complications in this cohort included one infection four months post-op, 6 post-operative knee manipulations, one pulmonary embolism and one
Not all degenerative knees need a total knee replacement. Over the last few decades we have shifted our surgical treatment of end-stage osteoarthritis (OA) of the knee to a “compartmental approach” resulting in approximately half of end-stage OA knees receiving a partial knee replacement. Of these an emerging procedure is isolated lateral compartment replacement with the indications being isolated bone-on-bone osteoarthritis or avascular necrosis of the lateral compartment of the knee. Associated significant patellofemoral disease and inflammatory arthritis are contraindications. The purpose of this study is to present the indications, surgical technique, and early outcome of lateral partial knees from our institution. From Aug 2011 until June 2017 we have performed 3,548 knee arthroplasties. Of these 147 were fixed bearing lateral partial knee replacements via a lateral parapatellar approach (4%), 1,481 medial partial knee replacements (42%), and 1,920 total knee replacements (54%). The average age was 66 years old and 76% were female. Average follow-up in the lateral partials was 1.3 years (range 0.5 years to 6 years). Knee Society Scores improved from 41 (pre-op) to 86 points (post-op). Range of motion improved from 6 – 113 degrees (pre-op) to 0 – 123 degrees (post-op). No knees were revised to a TKA. One knee required I&D for traumatic
In a recent study, 54.5% of patients reporting to arthroplasty clinics in the US were obese. We performed a recent literature review to determine how obesity impacts outcomes in total hip and knee arthroplasty and what must be done to improve outcomes in the obese arthroplasty patient. Specifically, obese patients have shown increased rates of infection, dislocation, need for revision,
Background. Readmission following any total joint arthroplasty has become a closely watched metric for many hospitals in the United States because financial penalties imposed by CMS for excessive readmissions occurring within thirty days of discharge has occurred since 2015. The purpose of this study was to identify both preoperative comorbidities associated with and postoperative reasons for readmission within thirty days following primary total joint arthroplasty in the lower extremity. Methods. Retrospective data was collected for patients who underwent elective primary total hip arthroplasty (CPT code 27130), total knee arthroplasty (27447), and total ankle arthroplasty (27702) from January 1, 2008, to December 31, 2013 at our institution. The sample was separated into readmitted and non-readmitted cohorts. Demographic variables, preoperative comorbidities, Charlson Comorbidities Index (CCI), operative parameters, readmission rates, and causes of readmission were compared between the groups using univariate and multivariate regression analysis. Results. There were 42 (3.4%), 28 (2.2%), and 1 (0.5%) readmissions within 30 days for THA, TKA, and TAA, respectively. The most common cause of readmission within 30 days following total joint arthroplasty in lower extremity was infection. Trauma was the second most common reason for readmission of a THA while
Prophylactic fixation of the contralateral hip in cases of unilateral slipped capital femoral epiphysis (SCFE) remains contentious. Our senior author reported a 10 year series in 2006 that identified a rate of subsequent contralateral slip of 25percnt; when prophylactic fixation was not performed. This led to a change in local practice and employment of prophylactic fixation as standard. We report the 10 year outcomes following this change in practice. A prospective study of all patients who presented with diagnosis of SCFE between 2004 and 2014 in our region. Intra-operative complication and post-operative complication were the primary outcomes. 31 patients presented during the study period: 16 male patients and 15 female patients. The mean age was 12.16 (8–16, SD 2.07). 25 patients had stable SCFE and 5 had unstable SCFE. Stability was uncertain in 1 patient. 25 patients had unilateral SCFE and 6 had bilateral SCFE. 24 patients who had unilateral SUFE had contralateral pinning performed. 1 unilateral SCFE did not have contralateral pinning performed as there was partial fusion of physis on contralateral side. In the hips fixed prophylactically there was 1 cases of transient intraoperative screw penetration into the joint and 1 case of minor
Arthrolysis and dynamic splinting have been used in the treatment of elbow contractures, but there is no standardised protocol for treatment of severe contractures with an arc of flexion <
30°. We present our results of radical arthrolysis with twin incisions with the use of a monolateral hinged fixator to treat very severe extra-articular contracture of the elbow. This retrospective study included 26 patients (15 males and 11 females) with a mean age of 30 years (12 to 60). The mean duration of stiffness was 9.1 months (5.4 to 18) with mean follow-up of 5.2 years (3.5 to 9.4). The mean pre-operative arc of movement was 15.6° (0° to 30°), with mean pre-operative flexion of 64.1° (30° to 120°) and mean pre-operative extension of 52.1° (10° to 90°). Post-operatively the mean arc improved to 102.4° (60° to 135°), the mean flexion improved to 119.1° (90° to 140°) and mean extension improved to 16.8° (0° to 30°) (p <
0.001). The Mayo elbow score improved from a mean of 45 (30 to 65) to 89 (75 to 100) points, and 13 had excellent, nine had good, three had fair and one had a poor result. We had one case of severe instability and one
Aim. Spinal implant-associated infections (SIAI) require combined surgical and antimicrobial treatment and prolonged hospital stay. We evaluated the clinical, laboratory, microbiological and radiological characteristics and treatment approaches in patients with SIAI. Method. Consecutive adult patients with SIAI treated between 2015 and 2017 were prosepctively included. SIAI was defined by: (i) significant microbial growth from intraoperative tissue or sonication fluid, (ii) intraoperative purulence, secondary
Background. Readmission following any total joint arthroplasty has become a closely watched metric for many hospitals in the United States because financial penalties imposed by CMS for excessive readmissions occurring within thirty days of discharge will be forthcoming in 2015. The purpose of this study was to identify both preoperative comorbidities associated with and postoperative reasons for readmission within thirty days following primary total joint arthroplasty in the lower extremity. Methods. Retrospective data was collected for patients who underwent elective primary total hip arthroplasty (CPT code 27130), total knee arthroplasty (27447), and total ankle arthroplasty (27702) from January 1, 2008, to December 31, 2013 at our institution. The sample was separated into readmitted and non-readmitted cohorts. Demographic variables, preoperative comorbidities, Charlson Comorbidities Index (CCI), operative parameters, readmission rates, and causes of readmission were compared between the groups using univariate and multivariate regression analysis. Results. There were 42 (3.4%), 28 (2.2%), and 1 (0.5%) readmissions within 30 days for THA, TKA, and TAA, respectively. The most common cause of readmission within 30 days following total joint arthroplasty in lower extremity was infection. Trauma was the second most common reason for readmission of a THA while
Peri-prosthetic wound infections can complicate total knee arthroplasty (TKA) in 1–1.5% of cases and may require the input of a combined orthopaedic and plastic surgery team. Failure of optimal management can result in periprosthetic joint infection, arthrodesis or in severe cases limb amputation. A retrospective 11-year review of TKA patients was undertaken in a single unit. Data was collected on a proforma and patient demographics were identified by case note analysis. Incidence of periprosthetic wound infections was recorded. A protocol to standardise treatment was subsequently developed following multidisciplinary input. 56 patients over 11 years developed periprosthetic wound infection. 33 patients were available for analysis. The male:female ratio 1:0.7 with a mean age of 70 years (range: 32–88 years). 5 (15%) developed superficial infections, 4 (12%) patients developed cellulitis requiring antibiotics, 14 (42%) with superficial

Infection is a complication in hip arthroplasty. It increases mortality and morbidity and is a cause for patient's dissatisfaction. Previous Works report an infection rate between 0,4% e 1,5% in primary hip replacement and between 3,2% in revision hip replacement. The aim of this work was to access the infection rates in one hospital, compare them with the reported rates and investigate possible risk factors for infection. Electronic clinical records were consulted. Patients who underwent total hip arthroplasty (primary or revision) or hemiarthroplasty in one hospital, between the 1st February 2011 and 31st February 2013, were included. Two hundred and sixty one patients (267 surgeries) were included. Demographically, 57,5% were female patients and 42,5% were male patients with an average age of 77,1 years (± 12,3 years). Infection rate for hemiarthroplasty 3,1%, for primary total hip arthroplasty was 1,4% and for revision procedures 4,8%. A statistically significant relation was found between arthroplasty infection and superficial wound infection (p<0,001),
Introduction. Knee arthroplasty is one of the most common inpatient surgeries procedures performed every year however complications do occur. Prior studies have examined the impact of insurance status on complications after TJA in small or focused cohorts. The purpose of our study was to utilize a large all-payer inpatient healthcare database to evaluate the effect of patient insurance status on complications following knee arthroplasty. Methods. Data was obtained from the Nationwide Inpatient Sample between 2004 and 2011. Analysis included patients undergoing knee arthroplasty procedures determined by ICD-9 procedure codes. Patient demographics and comorbidities were analyzed and stratified by insurance type. The primary outcome was medical complications, surgical complications and mortality during the same hospitalization. A secondary analysis was performed using a matched cohort comparing patients with Medicare vs private insurance using the coarsened exact matching algorithm. Pearson's chi-squared test and multivariate regression were performed. Results. Overall, 1,352,505 (57.8% Medicare, 35.6% private insurance, 2.6% Medicaid or uninsured, 3.3% Other) patients fulfilled criteria for inclusion into the study. Most were primary total knee arthroplasties (96.1%) with 3.9% revision knee arthroplasties. Multivariate regression analysis showed that patients with private insurance had fewer complications (OR 0.82, p=<0.001) compared to Medicare patients. Similar trends were found for surgical complications and mortality. Patients with Medicare or no insurance had more surgical complications but equivalent rates of medical complications and mortality. The matched cohort showed Medicare and private insurance patients had overall low mortality rates and complication. The most common complication was postoperative anemia, occurring in 16.2% of Medicare patients and 15.3% of patients with private insurance (RR=1.06, p<0.001). Mortality (RR 1.34),
Periprosthetic femoral shaft fractures are a significant complication of total hip arthroplasty. Plate osteosynthesis with or without onlay strut allograft has been the mainstay of treatment around well-fixed stems. Nonunions are a rare, challenging complication of this fixation method. The number of published treatment strategies for periprosthetic femoral nonunions are limited. In this series, we report the outcomes of a novel orthogonal plating surgical technique for addressing nonunions in the setting of Vancouver B1 and C-type periprosthetic fractures that previously failed open reduction internal fixation (ORIF). A retrospective chart review of all patients from 2010 to 2014 with Vancouver B1/C total hip arthroplasty periprosthetic femoral nonunions was performed. All patients were treated primarily with ORIF. Nonunion was defined as no radiographic signs of fracture healing nine months post-operatively, with or without hardware failure. Exclusion criteria included open fractures and periprosthetic infections. The technique utilised a mechanobiologic strategy of atraumatic exposure, resection of necrotic tissue, bone grafting with adjuvant recombinant growth factor and revision open reduction internal fixation. Initially, compression was achieved using an articulated tensioning device and application of an anterior plate. This was followed by locked lateral plating. Patients remained non-weight bearing for eight weeks. Six Vancouver B1/C periprosthetic femoral nonunions were treated. Five patients were female with an average age of 80.3 years (range 72–91). The fractures occurred at a mean of 5.8 years (range 1–10) from their initial arthroplasty procedure. No patients underwent further revision surgery; there were no
Introduction. Recurrent dislocation after hip arthroplasty is a difficult problem. The purpose of the present study was to evaluate the results with the use of a constrained cup for treatment for instability after hip arthroplasty. Materials/Method. A prospective database of 30 patients who underwent revision hip surgery for dislocation of hip arthroplasty was kept with the surgeries taking place between Nov 2005 to Feb 2010. Results. The mean age of the cohort was 76.5 years (53–93 years) with 17 female and 13 male patients. The gap between primary hip surgery and constrained cup ranged from 1 week to 21 years. The follow-up ranged from 8 months to 62 months with an average of 31 months. The primary surgery was a total hip arthroplasty in 27 patients and cemented hemiarthroplasty in 3 patients. Femoral component revision was done in 6 patients. At latest clinical follow-up 16 patients were mobilising unaided and 6 needed some support. Post-operative complications included capture cup pullout from the sidewall of the pelvis in the first week post op. Infection complicated 2 patients with one patient ending up having a girdlestone type excision and the other treated with antibiotic suppression. One patient had post op problems of
Surgical treatment of distal tibia fractures is usually associated with extensive soft tissue compromise and high complication rates (infection, delayed or non-union, ankle stiffness and osteoarthritis). Wound infection is one of the most common complication (deep infection rates up to 15%) and can develop into an infected non-union. In 1973, Papineau described a staged technique for treating infected non-union of long bones, consisting of (1) surgical debridement of necrotic tissue, temporary splinting, specific antibiotic treatment, postoperative wet-to-dry wound dressing changes; (2) packing of the bone defect with cortico-cancellous autograft; (3) closure of the soft-tissue wound by a flap or secondary intent. The authors aim to report a clinical case of a successful treatment of a distal tibia infected non-union with the Papineau technique and negative-pressure wound therapy. Woman, 56 years-old, referred to Orthopaedic consultation on October 2013 for
Wound complications are common in patients with soft tissue sarcomas (STS) treated with surgical excision. Limited data is available on predictive factors for wound complications beyond the relationship to neo-adjuvant or adjuvant radiotherapy. Likewise, the association between blood transfusion, patient comorbidities and post-operative outcomes is not well described. In the present study we identified the predictive factors for blood transfusion and wound complications in patients undergoing surgical resection of soft tissue sarcoma from a national cohort. The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients who underwent surgical resection of a STS from 2005 to 2013. Primary malignant soft tissue neoplasms were identified using the following ICD-9 codes: 171.2, 171.3 and 171.6. Patients treated with both wide excision and amputation were identified using the current procedural terminology (CPT) codes. Prolonged operative time was defined as greater than 90th percentile of time required per procedure. A multivariable logistic regression model was used to identify associations between patient factors and post-operative wound complications (superficial and deep surgical site infections (SSI), and wound dehiscence). A similar regression model sought to identify prognostic factors for blood transfusion and associations with post-operative outcomes. A total of 788 patients met our inclusion criteria. Of theses, 64.2% had tumours in the lower limb, 23.1% patients had tumours in the upper limb, and 12.7% patients had pelvic tumours. Six hundred and forty patients (81.2%) underwent surgical excision; 148 (18.8%) patients had an amputation. Multivariable logistic regression modeling identified American Society of Anaesthesiologist (ASA) class 3 and 4 (OR=2.3, P=0.03; OR=8.3, P=0.001, respectively), amputation (OR=14.0, P<0.001) and prolonged operative time (OR=4.6, P<0.001) as significant predictors of blood transfusion. Radiotherapy (OR=2.6, P=0.01) and amputation (OR=2.6, P=0.01) were identified as predictors of superficial SSI, whereas ASA class 4 (OR=6.2, P=0.03), prolonged operative time (OR=3.9, P=0.012) and return to the operating room (OR=10.5, P<0.001) were associated with deep SSI. Male gender (OR=1.8, P=0.03), diabetes (OR=2.3, P=0.03), ASA class 3 (OR=2.4, P=0.003), amputation (OR=3.8, P<0.001) and steroids (OR=4.5, P=0.03) were identified as predictors for
To evaluate the efficacy of Vacuum Assisted Closure (VAC) in the management of post surgical spinal sepsis. A retrospective analysis was performed of patients with severe post operative spinal wound infections treated using a combination surgical debridement, antibiotics and VAC therapy. Full records were available for a total of twenty adult all of whom had had prior thoracic or lumbar instrumentation. Comorbidities included disseminated carcinomatosis (25 % of patients), Ankylosing spondylitis (5 %), rheumatoid arthritis (5%) and Polio (5%). In one patient there had been a prior history of irradiation of the surgical field. Most infections treated by this regime were identified within two weeks following surgery. At surgery infection deep to the dorso-lumbar fascia was found in 87 % of cases. It was possible to retain instrumentation in 60 % of cases. An average of three trips to theatre were required prior to wound closure, which was possible in 95 % of cases. The VAC device was left in situ for an average of 11 days. Complications included recurrence of infection necessitating further treatment in 20 % of cases,
NICE guidelines state patients undergoing elective TKR receive post-operative chemical prophylaxis unless contraindicated, following guideline implementation our aim was to determine VTE incidence and wound complication outcomes related to administration of Rivaroxaban or Enoxaparin. From April to October 2010 we prospectively studied 294 patients having primary or revision TKR. Each received either Rivaroxoban (n=219), Enoxaparin (n=68), UHF 5000 units (n=4) or no thromboprohylaxis (n=3) post-operatively. Primary outcome was identification of symptomatic post-operative VTE incidence and compared incidence over the same period in 2009 when aspirin was the standard chemical prophylaxis for VTE. Secondary outcomes were prolonged wound oozing rates and wound washout. VTE occurred in 3 of 219 patients (2 PE, 1 DVT) receiving Rivaroxaban, and 1 PE in a patient who did not receive any thromboprophylaxis. No patients prescribed Enoxaparin developed VTE. In the same period 2009 there were 21 confirmed PEs in 512 patients undergoing TKR. This was statistically significant (Chi squared test p=0.02). Prolonged oozing was noted in 3 patients receiving Enoxaparin, and 17 patients receiving Rivaroxaban. 6 patients treated with Rivaroxaban returned to theatre, 3 for continuous ooze, 2 for
The incidence of wound complications after a hip or a knee replacement is well established, but there is no such data about foot/ankle surgery. Without this data it is difficult to compare performance between different care-providers. It is also difficult to benchmark services that could potentially be provided by a wide range of care providers (chiropodists, podiatrists, podiatric surgeons, general orthopaedic surgeons with a small foot/ankle practice, etc). Our aim was to establish the incidence of wound complications after foot/ankle surgery and provide a baseline for future comparison. Our study was done in two parts. First part was to conduct an opinion-survey of BOFAS members with a substantial foot/ankle practice, on wound complications from foot/ankle surgery in their own practice. Second part was to conduct a prospective study on the incidence of wound complications from our own foot/ankle practice. The study was registered as an audit and did not require ethical approval. All wound complications (skin necrosis,
Adequate range of knee motion is critical for successful total knee arthroplasty. While aggressive physical therapy is an important component, manipulation may be a necessary supplement. There seems to be a lack of consensus with variable practices existing in managing stiff postoperative knees following arthroplasty. Hence we did a postal questionnaire survey to determine the current practice and trend among knee surgeons throughout the United Kingdom. A postal questionnaire was sent out to 100 knee surgeons registered with British Association of Knee Surgeons ensuring that the whole of United Kingdom was well represented. The questions among others included whether the surgeon used Manipulation Under Anaesthaesia (MUA) as an option for stiff postoperative knees; timing of MUA; use of Continuous Passive Motion (CPM) post-manipulation. We received 82 responses. 46.3% of the respondents performed MUA routinely, 42.6% sometimes, and 10.9% never. Majority (71.2%) performed MUA within 3 months of the index procedure. 67.5% routinely used CPM post-manipulation while 7.3% of the respondents applied splints or serial cast post MUA. 41.5% of the surgeons routinely used Patient Controlled Analgaesia +/− Regional blocks. Majority (54.8%) never performed open/arthroscopic debridement of fibrous tissue for adhesiolysis. Knee manipulation requires an additional anaesthetic and may result in complications such as: supracondylar femur fractures,
Between April 1999 and December 2001 forty-one patients (forty-five femora) with metastatic lesions in the proximal femur involving intertrochanteric and subtrochanteric regions were stabilised with Proximal Femoral Nail (PFN). Thirty-eight patients (forty-two femora) were followed up for a mean period of 20 months (range 3 weeks to 35 months). There was an overall increase in mobility in 60% of the patients and the rest remained the same. Mean Preoperative Visual analog scale rating for thigh pain was 8.1 versus 3.4 for postoperative score (p<
0.01). There were no complications with respect to PFN. There were three post operative complications – chest infection, superficial
Background. The optimal treatment for pilon fractures remains controversial. We have used early single-stage open reduction and internal fixation to treat these injuries and the purpose of this study was to determine the safety and efficacy of this strategy. Methods. A cohort of 95 patients with AO type C tibial pilon fractures underwent primary ORIF. Of these patients, 21 had open fractures. Sixty-eight fractures were sustained in falls, 21 in motor vehicle collision, 5 in crushes and one in an aircraft crash. The principal outcome measure was
We studied the effects of the timing of tourniquet release in 88 patients randomly allocated for release after wound closure and bandaging (group A), or before the quadriceps layer had been closed allowing control of bleeding before suture (group B). The groups were similar in mean age, weight, gender, preoperative knee score, radiographic grading, and prosthesis implanted. Patients in group B had less postoperative pain, achieved earlier straight-leg raising, and had fewer wound complications. Five patients in group A had to return to theatre, three for manipulation under anaesthesia, one for secondary closure of
Rivaroxaban has been recommended for routine use as a thromboprophylactic agent in patients undergoing lower-limb arthroplasty. Starting January 2011, our unit has converted from aspirin to Rivaroxaban use routinely following lower-limb arthroplasty for venous thromboembolism (VTE) prophylaxis. The aim of this audit was to retrospectively review its efficacy and the morbidity associated with its use. All patients undergoing primary and revision lower-limb arthroplasty between February 2011 and July 2011 were reviewed. All patients undergoing total knee replacement surgery and total hip replacement surgery received oral rivaroxaban 10 mg daily post-operatively for 14 days and 35 days respectively. Outcome measures recorded were; investigation for DVT/PE, rate of DVT/PE, wound complications (infection, dehiscence, leaking, bleeding), blood transfusion rate and readmission rate within 6 weeks of surgery. Of the 162 patients identified, 19 were excluded due to insufficient information or because they did not receive rivaroxaban as VTE prophylaxis. 141 patients (mean age 71.7 years) were included. 69 primary and 5 revision total knee replacements were performed. 60 primary and 7 revision total hip replacements were performed. 9 patients (6.4%) underwent Doppler USS for a painful swollen leg with 1 (0.7%) DVT diagnosed. None were investigated for a pulmonary embolus. 25 (17.7%) patients developed wound complications: 10 superficial infections requiring oral antibiotics, 2 deep infections requiring theatre washout, 1
The aim of the study was to find out the relationship between delay in fixation of ankle fractures and incidence of wound complications like
Acromioclavicular joint dislocations (Grade 3) present challenging problems for the treating surgeon. We propose a retrospective radio clinical analysis of long-term outcome in a series of surgically treated patients to determine the long-term effects of the procedure on the acromioclavicular joint and possible implications for initial therapeutic decision. Twenty patients were reviewed at a mean 45, 5 months after surgery (range 8 – 85 months). Mean age at surgery was 45, 8 years. All had an Allmon grade 3 acromioclavicular dislocation. All had early surgery for open reduction of acromioclavicular dislocation and temporary stabilization with two parallel transacromioclavicular pins and a wire (tension band). Two patients had a postoperative complication: one
Introduction. The anterior approach to primary total hip arthroplasty is an unfamiliar approach to most surgeons that is considered to be minimally invasive based on the premise that there is less soft tissue damage and quicker post-operative recovery time. We present our experience of using the anterior approach exclusively by a single surgeon at multiple surgical centers for a period of 3.5 years. Method. 709 consecutive patients undergoing primary hip arthroplasties from 8/2007 to 12/2010 through a direct anterior approach were performed by single surgeon with extensive training in the approach. The procedure was performed with the patient supine on a fracture table (Trumph arch table extension) through an anterior approach as described by Dr. Joel Matta through a Smith-Peterson interval. Intra-operative data and complications were collected prospectively and to avoid missing any complications, electronic medical records (Alteer) were retrospectively reviewed. Results. The demographic characteristics of patients are listed in Table 1 and intra-operative data collected presented in Table 2. The overall major complication rate was 2.81% (19/709). Overall revision rate due to any cause was 1.83% (13/709). Wound related complications were 6.67% which included any type of drainage noted during post op clinic visits,
Objective: The purpose of this study was to determine which factors may influence in the outcome of the surgical treatment of Carpal Tunnel Syndrome (CTS). Material and Methods: During 2005, 175 patients were treated with the diagnosis of CTS by open carpal release (short palmar incision) without ligament reconstruction. 113 cases were selected: 39 males and 74 females, with an average age of 41 years (21 to 64 years) and a follow-up of 24 months (12–36 months). The dominant hand was treated in 58%. The subcutaneous cellular tissue (SCT) was sutured in 14% and 11% were immobilized with a cast for 2 weeks after surgery. We considered factors such as: systemic conditions, functional work requirement, preoperative time, surgical technique, and their correlation with complications, clinical outcome and time to return to work and activity level. Results: Complications: 41% pillar pain, 9% suture dehiscence, 3,5% ulnar neuritis, 1,7% trigger finger, 1,7% reflex sympathetic dystrophy, and 1,8% wound infection. 5 patients were re-operated. Complications rate due to surgery was 3,5% after 12 months of follow-up. The average time out of work was 9 weeks (2–43 weeks) and was higher (13 weeks) in patients with post-operative immobilization. All patients, except one, returned to their previous activity level. History of systemic conditions and dominance had not influence on the final outcome. The suture of the SCT and the postoperative immobilization showed lower
OBJECTIVE OF THE STUDY: Metatarsal osteotomies are common procedures for correction of hallux valgus. The aim of this study is to compare linear distal metatarsal osteotomy (LDMO) with SCARF osteotomy a clinical prospective randomised study. METHODS: Forty patients affected by bilateral hallux valgus similar in both sides regarding clinical and radiographic assessment were included. X-rays, AOFAS, Maryland Foot Score (MFS) were considered before surgery up to 4 years follow-up. All patients were operated bilaterally, and received SCARF osteotomy in one side, and in the other LDMO performed through a 1 cm skin incision under the direct view control. Duration of surgery was recorded. Postoperative care was similar in both groups and consisted of gauze bondage and weight bearing with talus shoes for 4 weeks. RESULTS: No statistical differences were observed in preoperative HVA, IMA, PASA in both groups. Average surgical time was 17 minutes in SCARF and 3 minutes in LDMO (p<
0.0005). No complications were observed in the series, with no
To evaluate first short term results of the 82 Articular Surface Replacements (ASR) of the hip joint with kinematic navigation. Between March 2006 and March 2007 we performed 82 resurfacings of the hip. In all cases we used Articular Surface Replacement of the Hip joint (ASR-DePuy) with kinematic navigation (Ci system). Our group included 47 women and 35 men. Patients’ mean age at surgery was 68.2 years. The indication for resurfacing was just primary osteoarthritis. Clinical evaluations were conducted using the Harris Hip Scoring system. Imaging studies: AP, axial X-rays. Patients were followed for an average 12 months postoperative (7–20 months). The average postoperative Harris Hip Total Score was 97%, and 98% of the patients were in the good to excellent range of 80–100 points. No patients were lost to follow-up. We noted a greater range of movement, faster postoperative rehabilitation and shorter time of hospitalization compared with traditional total hip arthroplasty. There were no cases of neurological complication, deep infection,
Purpose: The purpose of this study was to review our results in patients with pilon fractures treated with ORIF in which surgical planning involved multiple skin incisions, ensuring that the distance incisions overlapped was less than the distance between them. We hypothesized that soft-tissue complications would be minimal despite incisions placed <
7-cm apart. Method: A retrospective chart review identified 37 pilon fractures in 32 patients treated by three orthopedic traumatologists at The Ottawa Hospital between August 2000 and February 2007. Follow-up included measurements of incision placement and functional outcome measures. Results: There were nine OTA type B and 28 OTA type C fractures; 28 were closed and nine were open. The mean age was 46.5 ±14.5 years, and average follow-up was 3.2 ±1.7 years. Of the patients reviewed, the average number of incisions was 3.7 ±1.1. The average overlap between incisions was 4.6-cm ±1.9 and the average skin bridge between incisions was 5.9-cm ±1.9, with 80% of the skin bridges <
7-cm. Average ROM was 4.3° ±7.1 dorsiflexion and 39.1° ±11.6 plantarflexion. The mean AMA lower extremity impairment score was 18.9% ±12.4, and mean SIP ambulation score was 9.6 ±8.8. Complications included two superficial infections, one deep infection, and three non-unions. There were no cases of
Introduction: Congenital insensitivity to pain and anhydrosis (CIPA) is a rare genetic disease transmitted through an autosomal recessive mode. It is known also as HSAN (Hereditary Sensory and Autonomic Neuropathy) type 4. Affected patients suffer from: anhydrosis, mental retardation, poikilothermia and musculo-skel-etal anomalies. The actual knowledge on musculo-skel-etal aspects in CIPA is based on case reports. Aim of the study: To describe systematically the musculo-skel-etal aspects related to CIPA in a large group of patients followed over the years. Material and Methods: 40 patients with CIPA were followed in our institution. The age range was 3 months to 19 years of age, and the mean follow up was 8 years. There was some degree of relationship between the parents Their charts were reviewed, radiographs, and bacterial cultures were examined. Results: The main features that we observed: a) Joint instability with a spectrum that varies from positive provocative test to recurrent dislocation. b) Bone and Joint infection-often with high production of purulent discharges and associated with subluxation of affected joint or with pathologic fractures. Infections can be multimicrobial, are difficult to eradicate and lead to bacteremia episodes. c) Wound healing problems. Wounds hardly heal in CIPA patients. The scar is formed slowly if at all. Chronic sinus drainage and frequent
To map literature on prognostic factors related to outcomes of revision total knee arthroplasty (rTKA), to identify extensively studied factors and to guide future research into what domains need further exploration. We performed a systematic literature search in MEDLINE, Embase, and Web of Science. The search string included multiple synonyms of the following keywords: "revision TKA", "outcome" and "prognostic factor". We searched for studies assessing the association between at least one prognostic factor and at least one outcome measure after rTKA surgery. Data on sample size, study design, prognostic factors, outcomes, and the direction of the association was extracted and included in an evidence map.Aims

Surgical site infection (SSI) after soft-tissue sarcoma (STS) resection is a serious complication. The purpose of this retrospective study was to investigate the risk factors for SSI after STS resection, and to develop a nomogram that allows patient-specific risk assessment. A total of 547 patients with STS who underwent tumour resection between 2005 and 2021 were divided into a development cohort and a validation cohort. In the development cohort of 402 patients, the least absolute shrinkage and selection operator (LASSO) regression model was used to screen possible risk factors of SSI. To select risk factors and construct the prediction nomogram, multivariate logistic regression was used. The predictive power of the nomogram was evaluated by receiver operating curve (ROC) analysis in the validation cohort of 145 patients.Aims

This study documents the use of bone graft harvested by the RIA system and used in treating segmental bone loss in the femur and tibia following trauma. Eight patients with segmental defects of the tibia or femur were enrolled in the study. The segmental defects were optimized for bone grafting by repeated debridements and muscle flap coverage as required. Graft was harvested from the ipsilateral femur via a percutaneous technique. Volumes of bone graft were recorded and then placed to the defect site during the same surgical procedure. The average age of the patients was twenty-nine years (sixteen to forty-one years). In the five tibiae and three femora there were four grade IIIA, three grade IIIB and One grade IIIC injuries. Muscle flap coverage was required in four patients. The average size of defect was 7 cm (1–14.5 cm). The RIA grafting was performed at an average of three months (2.5 – 5 months) post injury. The average bone graft volume obtained was 73cc(45–90 cc). The average hemoglobin drop was 4.4g/dl(2.3 – 8.0 g/dl) and the average hematocrit drop was 12.3%(6–21%). One patient required transfusion. Donor site complications were limited to one post-operative bleed. Defect site complications included one
INTRODUCTION:. The popularity of the direct anterior approach (DAA) for total hip arthroplasty (THA) is increasing as this approach causes less soft tissue damage and no muscular detachments and significantly shorter postoperative recovery time. Despite the promising early results the complication rate in the DAA cases has been concerning such as 9% rate in 247 DAA cases reported by Woolen et. al [1]. As DAA has not conventionally being used by surgeons these complications are expected to be reduced when the surgeons are more experienced. Therefore to better understand the issues that cause the postop complications in DAA we have conducted the present study. OBJECTIVES:. The objective of the current study is to investigate the postop complications in individuals with arthritic hips treated by DAA THA over a period of 3.5 years by a one surgeon. METHODS:. The procedure was performed with the patient supine on a fracture table via DAA [2]. Briefly, the approach consisted of making a 8–10 cm incision 2 cm distal and lateral to the anterior superior iliac spine to a point several centimeters anterior to the greater trochanter. The dissection advanced to visualize the anterior capsule at the interval between the tensor and the sartorius and rectus femoris muscles. The neck was osteotomized at a pre-determined level through pre-operative templating. The acetabular component was prepared through sequential reaming followed by proper exposure for preparation of the femur, with sequential increasing size broaches used until a tight proximal fit was obtained with rotational stability. Hip stability with trial components was assessed by externally rotating the hip using the fracture table along with intra-operative radiographs. All post-operative clinic notes were reviewed retrospectively for any type of complication at any follow-up visit following primary THA. Intraoperative data and complications were collected prospectively. RESULTS:. 709 consecutive patients underwent primary hip arthroplasty from 8/2007 to 12/2010 via DDA performed by a single surgeon. The overall major complication rate was 2.81% (19/709). Overall revision rate due to any cause was 1.83% (13/709). Wound related complications were 6.67% which included any type of drainage noted during post op clinic visits,
The aim of this meta-analysis was to determine based on evidence from all randomised controlled trials whether closed suction drainage is preferable to no drainage for all types of Orthopaedic surgery. Trials were identified by a search strategy developed by the Cochrane Collaborative involving hand searching of major journals and computer aided searching of other databases. Twenty-nine studies were identified but nine were excluded owing to problems with study design or under-reporting of outcomes. Twenty studies involving 2749 patients with 2946 wounds were included in our analysis. These studies included 566 THRs, 860 TKRs, 333 proximal femoral fractures, 287 non-emergency fractures and 900 other procedures. Two reviewers independently extracted data from the papers. Methodology of the studies was assessed using a nine point scoring system. Generally the studies scored poorly, possibly owing to under-reporting of outcomes. No study clearly differentiated against deep and superficial wound infections therefore all wound infections were considered together. No differences between the drained and the undrained groups was noted for wound infection overall or in any of the operative sub-groups. Similarly no difference was found for the outcomes of wound haematomas, infection,
Aim: Our aim was to reduce the invasiveness of the THA approach in both primary and revision operations, in order to reach a better functional outcome, to facilitate patient’s rehabilitation and to minimize the encountered operation risks such as dislocation. To achieve our goal, we modified the conventional surgical technique by sparing and reconstructing the joint capsule as well as implanting an individually adapted hip ball size. Material and Methods: The LI-THA differs from the conventional THA in the following aspects:. Selecting the most appropriate size of hip ball among a different variety ranging from 28–44 mm in diameter, in order to simulate the size of the resected femur head and increase the joint stability as much as possible. Sparing and completely reconstructing the joint capsule, especially its acetabular origin. Muscular and iliotibial tract incisions are made parallel to the direction of fibres in order to facilitate optimal surgical reconstruction. Small skin incision together with using absorbable subcuticular skin closure technique to reduce postoperative wound complications. 1004 cases of primary THA and 36 cases of THA revision were evaluated after applying the less invasive technique. A questionnaire was designed to evaluate the patient’s satisfaction regarding pain and function, necessary reoperations, complications such as dislocation or
Aim: To evaluate the repair of articular cartilage defects in the knee treated by autologous chondrocyte implantation (ACI), using arthroscopic assessment. Method: One hundred and six articular cartilage defects in 79 knees of 77 patients were treated by ACI. The chondrocytes were injected beneath a periosteal flap (Brittberg et al, 1994). Arthroscopy and removal of the metal implants were performed nine months following implantation. The ICRS score was used to assess the repairs. Results: Of the 79 knees 43.5% of the lesions involved the patella, 35.2% the femoral condyles, 16.7% the trochlea, and 4.6% the tibial condyles. The average defect size was 254.65mm. 2. It was found that 20% of knees had more than one defect. Associated biomechanical procedures were carried out in 88.7%. Seventy lesions in 58 knees (56 patients) have been assessed; four eligible patients were not assessed arthroscopically. The ICRS scores (maximum 12) were: tibial condyle 11.5; patella 11.3; femoral condyle 11.0, and trochlea 10.7. Synovitis was markedly reduced in all knees with well-healed defects. Adhesions between the periosteal graft and the synovium caused a click in 11 patients, which was relieved by arthroscopic resection. Incomplete healing occurred in one patient with a
Introduction: The main goal of surgical correction of hallux valgus is the morphological and functional rebalance of the first ray and correcting all the characteristics of the deformity. Historically, distal metatarsal osteotomies and SCARF have been indicated in cases of mild or moderate deformity with inter-metatarsal angles up to 20° and are procedures widely used for correction of hallux valgus. The aim of this study is to compare a distal metatarsal osteotomy recently described (SERI) with SCARF osteotomy in a clinical prospective randomised study. Methods: 20 patients with bilateral hallux valgus similar on both sides regarding clinical and radiographic assessment were included. Clinical evaluation using American Orthopaedic Foot and Ankle Score (AOFAS) and radiographic assessment were considered before surgery up to 2 years follow-up. All patients were operated bilaterally in the same surgical sitting, and received at random SCARF osteotomy on one side, and on the other a SERI osteotomy performed through a 1 cm skin incision under tdirect view control and fixed with one Kirschner wire. Duration of surgery was recorded. Postoperative care was similar in both groups and consisted of gauze bandage and weight bearing with talus shoes for 30 days. Results: No statistical differences were observed in preoperative HVA, IMA, DMAA in both groups. Average surgical time was 17 minutes in SCARF and 3 minutes in SERI (p<
0.0005). No complications were observed in the series, with no
Deep prosthetic infections are a significant cause of failure after arthroplastic surgery. Superficial wound infections are a risk factor for deep infections. We aimed to quantify the risk of deep infection after superficial wound infections, and analyse the microbiology of organisms grown. We defused Superficial Infection according to the definition used by the Centre for Disease Control, and Deep Infection according to the Swedish Hip Register. We retrospectively analysed the results of 6782 THR and TKRs performed consecutively from 1988–1998. We analysed patient records, radiology and microbiological data. The latter collected prospectively by our infection control team. We identified 81 (1. 2%) superficial wound infections, however we had to exclude 3 due to poor follow-up. Of the 78 patients studied, mean age was 71 (23–89), 50 were female, 28 male, 41 THR, 37 TKR and follow-up was a mean 49 months (12–130). The majority (81%) of organisms grown in the superficial wound infections were gram positive Staphylococci. These organisms were most frequently sensitive to Erythromycin or Flucloxacillin. All the superficial infections were treated with antibiotics, 66% settled with less than 6 weeks therapy. Deep prosthetic infections occurred in 10% of superficial infections in both THR and TKR. In 80% of cases the organism in the superficial infection caused the deep infection.
Due to the increasing rate of relapses and the morbidity degree that this implies, we report our experience and results in the treatment of clubfoot in patients with myelomeningocele. Between February 1996 and February 2001 12 patients with myelomeningocele (16 feet with clubfoot deformity and 4 bilateral cases) underwent surgical treatment. 5 were boys and 7 were girls. 3 relapsed cases were referred to our institution, 1 of them had a bilateral involvement. The average age at time of surgery was 27 months (range 7 months–5.3 years). Levels of functional involvement were recorded according to Caneo (Argentina Chapter of Neuroorthopaedics) classification: Caneo 0: 2 patients, Caneo 1: 4 patients, Caneo 2: 8 patients, Caneo 3: 1 patient. Relapses occurred in 3 cases; 2 with tendon lengthening technique and 1 tibialis posterior transfer to lateral peroneus brevis, split tibialis anterior tendon transfer. The complications were postoperative infection in 3 cases with
We apply a hydrocolloid-gel sheet (C-12, Karayaheive, Alcare, Tokyo, Japan) for the hip arthroplasty. The sheet is a kind of wound dressing film made of the Hevea sap. The Hevea sap has been widely applied for the stoma or cosmetics (e.g. facial mask, UV protection moisturizer, hair lotion). We use it since October 2004. It applies the moist wound healing mechanism without preventing the self-wound-healing. The surgical exudate is kept under the sheet to apply the moist wound healing mechanism. The sheet had been improved originally as a wound dressing material. Because of its very strong adhesiveness, we use it also as an alternative to the epidermal suture. In our method, we do not use any epidermal suture or staples. We use an anterolateral approach making an arcate incision. After the subcutaneous tissue was sutured just like as in the case of using the epidermal sutures or staples, the sheet was attached to the skin. Both the sheet and the overlaying gauze were not changed until the removals on the tenth day after surgery. We have applied this wound closure method for 814 primary surgeries. Among them, we evaluated 56 hips in 49 patients (three males and 46 females) (including seven patients of the simultaneous bilateral surgery) with minimum of two years follow-up. The average age at the surgery was 61 (40 to 77). The diagnosis at the surgery was dysplastic osteoarthritis for 50 hips in 45 patients, primary osteoarthritis for five patients in three hips, and rheumatoid arthritis for one hip. The uncemented implants were used for all patients. In all patients, a good wound healing was obtained. The
Periprosthetic joint infection (PJI) demonstrates the most feared complication after total joint replacement (TJR). The current work analyzes the demographic, comorbidity, and complication profiles of all patients who had in-hospital treatment due to PJI. Furthermore, it aims to evaluate the in-hospital mortality of patients with PJI and analyze possible risk factors in terms of secondary diagnosis, diagnostic procedures, and complications. In a retrospective, cross-sectional study design, we gathered all patients with PJI (International Classification of Diseases (ICD)-10 code: T84.5) and resulting in-hospital treatment in Germany between 1 January 2019 and 31 December 2022. Data were provided by the Institute for the Hospital Remuneration System in Germany. Demographic data, in-hospital deaths, need for intensive care therapy, secondary diagnosis, complications, and use of diagnostic instruments were assessed. Odds ratios (ORs) with 95% confidence intervals (CIs) for in-hospital mortality were calculated.Aims
Methods
Purpose: The Oxford unicompartmental prosthesis has congruent joint surfaces due to use of a mobile meniscus whose upper part matches the sphere constituted by the femoral component. The purpose of this work was to report results in a series of 75 prostheses studied with mean follow-up of 12.4 years (range 10–14 years). Material and methods: Mean age of patients was 65 years (38–84), with 67% women and mean body mass index of 28.7 (21.2–40.6). Patients gave their subjective assessment of the arthroplasty and the IKS scores were determined. Radiographically, the mechanical alignment of the lower limb was evaluated pre- and postoperatively on the full stance images. The Kennedy classification (4 grades) was used to assess passage of the mechanical axis through the knee. Results: At last follow-up, three patients were lost and eight had died. According to their subjective assessment, 84% of the patients were enthusiastic or satisfied. The overall IKS score showed that 52% of the patients were above 180 points, 25% above 150 points. Mean varus was 11° (2–24°) preoperatively and 5.7° (5° valgus to 14° varus) at last follow-up. The mechanical axis passed in the sufficient correction zone (c or 2) in 77% of the knees, undercorrection zone in 17% and in the overcorrection zone in 6%.Seven prostheses were revised for mechanical failure: four for loosening, two for extensive degeneration, and one for pain giving a survival curve of 90% at 12 years. It must be added that two meniscal dislocations occurred, one early due to
Introduction. Joint reconstruction remains a successful and popular surgery with advances in approaches, implants and techniques continually forthcoming. Various methods of skin closure exist to address issues in efficiency, aesthetics, and barrier to infection. While subcuticular skin closure techniques offer an aesthetic advantage to conventional skin stapling, no measurable differences have been reported. Furthermore, newer barbed sutures, such as the V-loc absorbable suture, theoretically distribute tension evenly through the wound and help decrease knot-related complications. To our knowledge, no literature exists on the rate of wound complications in joint arthroplasty with the use of V-loc suture for skin closure. We hypothesize that despite theoretical gains, skin closure with a V-loc (Covidien, Mansfield, MA) absorbable suture should be performed with caution. Methods & Materials. A retrospective chart review was conducted of 278 consecutive primary joint reconstruction cases performed by a single surgeon in 12 months from July 2009 through June 2010. Pre-operative history & physical reports were evaluated for co-morbidities (i.e diabetes mellitus), smoking status and body mass index (BMI). Operative dictations by the attending surgeon provided information on the surgical procedure, use of drain, wound closure technique and type of suture/staple used for skin closure. Skin was closed by the primary surgeon and his chief resident. Wounds were closed via staple gun or subcuticular stitch (3-0 Biosyn vs V-Loc) in a consecutive manner, depending on the surgeon's preference in that period. Post-operative clinic notes were reviewed to determine the occurrence of wound complications, issuance of antibiotic prescriptions, or return to the operating room. The cohort consisted of 106 males and 161 females at an average age of 63 years (range: 18–92). Overall, there were 153 procedures at the knee (including TKA, uni-compartmental arthroplasty, patello-femoral arthroplasty) and 125 procedures at the hip (including THA and hemi-arthroplasty). Results. In review of 278 consecutive primary joint reconstruction cases, there were 17 (6.1%) post-operative wound complications noted, including cellulitis, stitch abscesses,
Hallux valgus deformity may cause overriding of the second toe. Hallux valgus correction surgery in the elderly can be debilitating and patients may suffer a long period of morbidity. We show the outcomes of amputation of over-riding second toe caused by gross hallux valgus in the elderly. Eight patients underwent amputation of their overriding second toe, one of these patients underwent bilateral second toe amputations. All surgery was performed as a day case. Six patients had surgery under a local anaesthetic, two patients had surgery under a general anaesthetic. Patients selected had asymptomatic or minimally symptomatic hallux valgus with an overriding second toe and did not want hallux valgus correction surgery. A disease specific questionnaire using a Visual Analogue Scale (VAS) was implemented measuring pain, discomfort, deformity and walking distance. Patients were followed up for a minimum nine of months. Eight patients (nine feet) underwent amputation of their second toe. There were seven females and one male. The age range was 63–90 years (median 83 years). All patients had a painful second toe on wearing footwear. Skin ulceration occurred on the dorsum of second toe in two patients. The mean VAS for pain, deformity, discomfort and walking distance before and after surgery are:- (before/after); pain = (7.00/0.94), deformity = (7.44/2.78), discomfort = (7.78/1.22) and walking distance = (6.89/6.44). There were no cases of post-operative infection,
The purpose of this study was to determine the surgical risks and recurrence rate associated with the excision of osteochondroma from the long bones most frequently operated on in our institution; the femur, tibia, humerus and fibula. Two hundred and twenty four osteochondromata were excised in total between July 1992 and January 2001. The medical records and radiographs of 126 patients who had 147 osteochondromata excised from the femur, tibia, humerus and fibula were reviewed. Of these, 30 patients presented with multiple osteochondromata, accounting for 48 of the 147. Fifty three involved the femur (2 proximal), 55 the tibia (16 distal), 12 the fibula (2 distal) and 27 the proximal humerus. The mean age at excision was 12.5 years (2–18 years) and the mean follow-up was five years (1 to 10 years). There were 15 surgical complications (10% of excisions) including one compartment syndrome, five superficial wound infections, two haematoma formations which required evacuation, one partial
Introduction The aim of the study was to review the results of total hip arthroplasty (THA) in relatively fit and mobile patients with Garden 3 and 4 fractures of the neck of femur. Materials and methods 42 patients with displaced hip fractures who underwent THA ≥ 3years ago were reviewed. One was lost to follow-up. Results Average age was 67.17 years (SD-9.4, range 37–80 years) with Male:Female ratio 6:35. Average follow-up was 5.8 years (3–9.6 years). Average Modified Barthel index before the fracture was 18.63 (SD-2.08, range 13–20). Majority were ASA grade II (22 patients). 33 hips were cemented, 1 uncemented and 7 hybrids. Canulated CF-30 femoral stem was most commonly used (33 patients) and acetabular component was Weber cup in most cases (34 patients). 35 hips had metal-on-metal bearing surface and the rest had metal-on-polyethylene. Average hospital stay was 12.5 days (SD-7.84, range 6–43); majority (36) of the patients were discharged home and the rest needed additional rehabilitation. Average post-operative drop in Hb was 2.78 (SD-1.34) and 15 (36.5%) patients needed blood transfusion. Average transfusion was 0.85 units per patient. Complications included: minor
Introduction The aim of the study was to review the results of total hip arthroplasty (THA) in relatively fit and mobile patients with Garden 3 and 4 fractures of the neck of femur. Materials and methods 37 patients who underwent THA for displaced fractures of neck of femur between 1995 to 2001 were reviewed. Only those patients with 3 years or more follow-up were reviewed. Results Average age was 67.7 years (37–80 years) with Male:Female ratio 5:32. Fracture involved left hip in 12 and right hip in 15 patients. Average Modified Barthel index before the fracture was 18.5 (13–20) and average Waterlow score was 12 (5–19). Majority were ASA grade II (22 patients). All patients were operated by the senior author. 31 hips were cemented, 1 uncemented and 5 hybrids.

Introduction: In cases of severe, rigid scoliotic curves, anterior or posterior fusion alone is inadequate and surgical treatment with a combined anterior and posterior) approach is required. The purpose of this study is to evaluate the effectiveness and the complications of these lengthy procedures. Material and Methods: Between 1993 and 2002, 125 patients with scoliosis were surgically treated in our department. A total of 18 patients with scoliosis were treated with a combined anterior and posterior approach. The mean age of these patients was 19.6 years (range 5.5 – 60 years). Fourteen patients were subjected to a single-stage procedure, while 4 patients underwent a staged procedure. Thirteen patients underwent anterior release and posterior nstrumentation, while 5 patients underwent both anterior and posterior instrumentation. Additional thoracoplasty was performed in 3 cases. The mean duration of the operation was 12.1 hours (range 4.5 – 14 hours). All patients were monitored postoperatively in the Intensive Care Unit. The mean duration of follow-up was 4.5 years (0.6 – 9 years). Results: Anterior release and posterior instrumentation achieved a mean 30% correction of curves that were corrected by only 15% with traction preoperatively. Combined anterior and posterior nstrumentation achieved a mean 44% correction of curves that were corrected by only 22% with traction preoperatively. One patient presented residual pneumothorax that was treated with chest tube. One patient with neuromuscular scoliosis presented
Introduction: The usual surgical treatment of valgus knee in Ellis van Creveld Syndrom (EVC), is high tibial osteotomy. However, this approach failed to achieve the expected goal of lasting correction. Based on Dr. Paley’s observations, and our previous unsuccessful treatment of valgus knee in EVC syndrome, we changed the surgical approach. The aim of the surgical treatment is to eradicate all the elements causing sever valgus knee: 1) dysplasic lateral tibial condyle, 2) progressive depression of the lateral tibial plateau, 3) short fibula, 4) short and contracted fascia lata, 5) short lateral collateral ligament and biceps femoris, 6) short lateral head of gastrocnemius, and 7) contracted lateral knee capsule and lateral retinaculum. In many aspects the pathology of Blount’s disease grade 5 or 6 is similar, but located at the medial tibia causing genu vara. Materials and Methods: Three valgus knees of EVC syndrome and two varus knees of Blount’s disease grade 5 &
6 underwent surgical treatment by a unique surgical approach to address all pathologies which contribute to the deformity. In the cases of EVC syndrome the first stage operation included: 1) peroneal nerve release and soft tissue release including T.F.L., B.F., L.C.L., capsule and gastrocnemius, 2) arthrogram, 3) fibulectomy, 4) elevation of lateral tibial plateau with bone graft, 5) reconstruction of L.C.L. and B.F., 6) lateral release of retinacula and rerouting of patella, and 7)cast application. In the second stage operation of these cases a corrective high tibial osteotomy was performed. In the Blount’s disease knees the operative treatment was performed in one stage and included: 1) arthrogram, 2) elevation of the medial tibial plateau, 3) fibulotomy, 4) closing wedge tibial osteotomy based laterally, 5) transfer of the bony wedge under the elevated plateau and fixation. Results: All deformities were corrected with no recurrence, and stability of the knees persisted. We had one common peroneal nerve neuropraxia that recovered and one
Introduction and Aims: The purpose of this study was to report our results of surgical resection of plantar fasciosis without a full release using a small transverse plantar incision. Method: All patients who had a surgical resection for plantar fasciosis at our institution from July 1992 to November 2000 were identified. All surgeries were performed by the senior author (R.P.N.). A small transverse plantar incision was utilised. The focus of the operative technique was identification and resection of only the pathologic fasciosis tissue. A full release of normal plantar fascia was not performed, and the associated calcaneal traction spur was addressed only if easily accessible with the fasciosis resection. Patients were then contacted and asked to fill out a scoring sheet developed at our institution that relates to pain, function, and patient satisfaction after plantar fasciosis resection. This was compared to a scoring sheet that rated the same parameters just prior to surgery. A Wilcoxan signed ranks test was used to compare the results. The incidence of patient and physician noted wound complications were also recorded. Results: Twelve patients had 15 plantar fasciosis resection operations between July 1992 and November 2000. Of these 12, three were lost to follow-up. The remaining nine patients, four men and five women, had 12 operations (three were bilateral). The ages of the patients at time of surgery ranged from 34 to 72 years. Time of follow-up ranged from two to 10 years (average 6.25 years). There were six left and six right feet for comparison. The pain rating of patients improved from a median of five to 25 (p=0.011). The functional score improved from a median of 3.75 to 25 (p=0.007). The satisfaction of the patients improved from a median of zero to 15 (p=0.007). Patients reported no complaints of
Neoadjuvant therapy in soft-tissue sarcomas is still a controversial issues regarding indications, patients selection and treatment protocols. In the last fifteen years (1990–2005) at our Institution more than 600 patients affected by soft tissue sarcomas of the limbs and superficial trunk were surgically treated. Among these patients, 49 received preoperative chemotherapy (epirubicin plus ifosfamide, according to Italian Sarcoma Group protocol), associated to preoperative conventional external beam radiationtherapy in 36 cases (73.5%). The histologic types were liposarcoma (30,6%), synovial sarcoma (20,4%), fibrosarcoma (16,3%), pleomorphic sarcoma or malignant fibrous histiocitoma (12,1%), leiomyosarcoma (8,2%), other histotypes (12,1%). Tumor size was 10 cm or larger in 21 cases, 6 to 9 cm in 23 patients and 5 cm or smaller in 5 cases. Neoplasms were high-grade (Broders grade 3 or 4) in all cases but five. After neoadjuvant treatment we performed a limb-sparing surgical excision of the tumor in 47 patients (96%), while a primary amputation of the limb was necessary in only two cases (4.1%). A vascularized miocutaneous flap was used in 8 cases, and adequate surgical margins were achieved in more than 70% of the cases. Postoperative chemotherapy was given in 26 cases (53%), postoperative radiotherapy just in 5 (10%). We report the outcome data on these 49 cases, regarding overall survival, local or distant relapse, local and systemic complications, early and long-term limb salvage rate. According to histologic examination of the resection specimen, average percent of necrosis after neoadjuvant treatment was 70.6% (range 30 – 99%).
The Gibson and Moore postero-lateral approach is one of the most often used in hip replacement. The advantage of this approach is an easy execution but it's criticized because of its invasivity to muscle-tendinous tissues especially on extrarotators muscles and because of predisposition to posterior dislocation. Since June 2003 we executed total hip replacements using a modified postero-lateral approach which allows to preserve the piriformis and quadratus femoris muscles and to detach just the conjoint tendon (gemelli and obturator internus). Articular capsule is preserved and it will be anatomically sutured at the end of the procedure as well as the conjoint tendon with two transossesous sutures. Piriformis and quadratus femoris muscles result untouched by this approach. We have executed 500 surgeries with this modified approach. We have used different stems (straight, anatomical, modular and short) and press fit acetabular cup with polyethylene or ceramic insert and we have always used 36 mm femoral heads when allowed by the cup dimensions. We have used any size both of stems and cups without limitation due to the surgical approach. The mean age is 61.8 y.o., 324 females and 176 males. Obese patients, hip dysplasia Crowe 3 and 4 and post traumatic arthrosis are exclusion factors for the execution of this approach. If possible we have maintained the capsulo-tendinous less invasivity. The BMI is not an excluding factor because it's just the gluteus region that is an important factor to decide if to execute or not a less invasive approach. Analyzing our 500 cases we didn't have any case of malpositioning of the stem in varus or valgus (more than 5°) and considering acetabular cup we had the tendency to position it in valgus position (not more than 40°) in the first 20 cases. No leg discrepancy more than 1 cm were observed. Intra-operative blood loss have been reduced of about 30 % and 50% in the post-operative. All the patients were able to active hip mobilization within the first day after surgery with a mean range of motion of 0-70°. The patients were mobilized the first day after surgery and 80% of them were able to assisted walk within second day after surgery. The mean time of stay in hospital was 6.8 days. After 4 weeks 98% of the patients were able to walk without crutches. One case of deep infection were evaluated and then solved with surgical debridement; no
Purpose of the study: The place for total ankle arthroplasty versus fusion remains a subject of debate for the treatment of painful stiff ankles. Material and methods: This series included 58 total ankle arthroplasies performed in 56 patients between 1991 and 2003. Mean paient age was 52 years (range 27–84). The underlying cause was multiple trauma (n=27), rheumatoid arthritis (n=17), chronic instability (n=11), hemophilia (n=2), primary disease (n=1). Four implants were used: New Jersey (n=22), Albatros (n=4), Star (n=10), AES (n=22). Associated procedures were: lengthening of the Achilles tendon or vastus (n=28), lateral ligamentoplasty (n=6), fibular osteotomy (n=2), medial ligamentoplasty (n=1), calcaneal osteotomy (n=3), double arthrodesis (n=1). The patients wore a plaster cast for 21 to 40 days. Results: Eight patients were removed from the analysis: death (n=4), foreign residence (n=1, 3 follow-up shorter than one year (n=3). The analysis retained 50 total ankle arthroplasties in 48 patients reviewed with a mean 49 months follow-up (range 1–12 years). Reasons for surgery were: trauma (n=25), rheumatoid disease (n=12), instability (n=10), hemophilia (n=2), primary (n=1). Implants were: New Jersey (n=17), AES (n=19), Star (n=9), Albatros (n=3). Complications were: intra-operative medial malleolar fractures which were pinned (n=8), immediately revised radiological instability (n=2),
The Gibson and Moore postero-lateral approach is one of the most often used in hip replacement. The advantage of this approach is an easy execution but it’s criticized because of its invasivity to muscletendinous tissues especially on extrarotators muscles and because of predisposition to posterior dislocation. Since June 2003 we executed total hip replacements using a modified postero-lateral approach which allows to preserve the piriformis and quadratus femoris muscles and to detach just the conjoint tendon (gemelli and obturator internus). Articular capsule is preserved and it will be anatomically sutured at the end of the procedure as well as the conjoint tendon with two transossesous sutures. Piriformis and quadratus femoris muscles result untouched by this approach. We have executed 500 surgeries with this modified approach. We have used different stems (straight, anatomical, modular and short) and press fit cetabular cup with polyethylene or ceramic insert and we have always used 36 mm femoral heads when allowed by the cup dimensions. We have used any size both of stems and cups without limitation due to the surgical approach. The mean age is 61.8 y.o., 324 females and 176 males. Obese patients, hip dysplasia Crowe 3 and 4 and post traumatic arthrosis are exclusion factors for the execution of this approach. If possible we have maintained the capsulo-tendinous less invasivity. The BMI is not an excluding factor because it’s just the gluteus region that is an important factor to decide if to execute or not a less invasive approach. Analyzing our 500 cases we didn’t have any case of malpositioning of the stem in varus or valgus (more than 5°) and considering acetabular cup we had the tendency to position it in valgus position (not more than 40°) in the first 20 cases. No leg discrepancies more than 1 cm were observed. Intra-operative blood loss have been reduced of about 30 % and 50% in the post-operative. All the patients were able to active hip mobilization within the first day after surgery with a mean range of motion of 0–70°. The patients were mobilized the first day after surgery and 80% of them were able to assisted walk within second day after surgery. The mean time of stay in hospital was 6.8 days. After 4 weeks 98% of the patients were able to walk without crutches. One case of deep infection were evaluated and then solved with surgical debridement; no
Introduction: The literature regarding the functional outcome following C1–C2 surgeries for non-rheumatoid C1–C2 pathologies following selective arthrodesis is sparse. Aim: To determine the long term correlation between functional outcome and radiological determinants following C1–C2 fusion for conditions other than RA. Methods: All C1–C2 surgeris performed between 1988–2002 for non-RA etiologies were reviewed retrospectively. Selective C1–C2 fusion performed in 32 pts with a min f/u of 5 yrs formed the study group. The mean age at surgery was 57.2 yrs (r 22–84yrs). The etiologies were trauma (15), non-union (6), congenital AAD (2), C1–C2 deg. arthropathy (2), os odontoideum (2), tumours (4) and instability due to TB (1). Neurodeficit were present in 7 pts. Transarticular (TA) screws supplemented with posterior wiring was performed in 27 &
posterior wiring alone in 5 pts respectively. A monocortical H-shaped autograft from iliac crest was used in all cases. There were two deaths &
two pts were lost for F/U. The mean F/U was 7.8 yrs (r 5–13 yrs). Disability &
pain using NDI &
VAS and subjective satisfaction were recorded in all pts. We measured 1) C1/2 fixation angle, 2) Inclination of C1, 3) Anterior shift of C2 and 4) C2–7 lordosis on pre and final F/U lateral x-rays. Results: Optimal TA screw placement was seen in 78.5% of pts. The mean improvement in NDI &
VAS were from 55.4% to 19.6% and 8.4 to 1.6 respectively and was better in younger pts. Fusion was seen radiologically in 82.1% of pts at 12 mo post surgery. Segmental stability and resolution of symptoms was seen in all patients despite implant failure in 4 and incomplete fusion 5 cases respectively. Two
This systematic review aimed to summarize the full range of complications reported following ankle arthroscopy and the frequency at which they occur. A computer-based search was performed in PubMed, Embase, Emcare, and ISI Web of Science. Two-stage title/abstract and full-text screening was performed independently by two reviewers. English-language original research studies reporting perioperative complications in a cohort of at least ten patients undergoing ankle arthroscopy were included. Complications were pooled across included studies in order to derive an overall complication rate. Quality assessment was performed using the Oxford Centre for Evidence-Based Medicine levels of evidence classification.Aims

This study aimed to investigate the risk of postoperative complications in COVID-19-positive patients undergoing common orthopaedic procedures. Using the National Surgical Quality Improvement Programme (NSQIP) database, patients who underwent common orthopaedic surgery procedures from 1 January to 31 December 2021 were extracted. Patient preoperative COVID-19 status, demographics, comorbidities, type of surgery, and postoperative complications were analyzed. Propensity score matching was conducted between COVID-19-positive and -negative patients. Multivariable regression was then performed to identify both patient and provider risk factors independently associated with the occurrence of 30-day postoperative adverse events.Aims

Chemical prophylaxis is known to reduce the venographic prevalence of deep-vein thrombosis (DVT) after total knee replacement (TKR), but it is uncertain whether this affects the incidence of symptoms. Further analysis depends on the basic epidemiology of thromboembolic symptoms. We therefore studied the pattern of such symptoms in a consecutive series of 1000 patients with primary TKR, with particular reference to risk factors and prophylaxis. We reviewed all the clinical records and contacted all the patients individually, noting risk factors, prophylaxis, symptomatic pulmonary embolus (PE) or DVT and its timing, death and its causes, and all complications. All the patients wore antiembolism stockings, 83% had regional anaesthesia and 33.9% had chemical prophylaxis. One patient died from PE on the day of surgery, having had no prophylaxis giving a rate of 0.1% (95% CI 0.003% to 0.56%). Symptomatic, radiologically confirmed thromboembolism (VTE) was common with a rate of 10.6% (95% CI 8.7% to 12.5%). There was a similar incidence of VTE in those with and without chemical prophylaxis (10.1% v 10.5%, RR 0.96, NS). VTE was more common in patients with risk factors (15.1% v 9.5%, RR 1.59, p = 0.02) and tended to occur earlier in this group (median day of onset 5 v 7, p = 0.01). Chemical prophylaxis did not reduce the frequency of symptomatic thromboembolism in either those with risk factors (RR 0.81, p = 0.5) or those without them (RR 0.94, p = 0.8). Haematoma or
Surgical reconstruction of deformed Charcot feet carries a high risk of nonunion, metalwork failure, and deformity recurrence. The primary aim of this study was to identify the factors contributing to these complications following hindfoot Charcot reconstructions. We retrospectively analyzed patients who underwent hindfoot Charcot reconstruction with an intramedullary nail between January 2007 and December 2019 in our unit. Patient demographic details, comorbidities, weightbearing status, and postoperative complications were noted. Metalwork breakage, nonunion, deformity recurrence, concurrent midfoot reconstruction, and the measurements related to intramedullary nail were also recorded.Aims

The use of cementless total knee arthroplasty (TKA) components has increased during the past decade. The initial design of cementless metal-backed patellar components had shown high failure rates due to many factors. The aim of this study was to evaluate the clinical results of a second-generation cementless, metal-backed patellar component of a modern design. This was a retrospective review of 707 primary TKAs in 590 patients from a single institution, using a cementless, metal-backed patellar component with a mean follow-up of 6.9 years (2 to 12). A total of 409 TKAs were performed in 338 females and 298 TKAs in 252 males. The mean age of the patients was 63 years (34 to 87) and their mean BMI was 34.3 kg/m2 (18.8 to 64.5). The patients were chosen to undergo a cementless procedure based on age and preoperative radiological and intraoperative bone quality. Outcome was assessed using the Knee Society knee and function scores and range of motion (ROM), complications, and revisions.Aims

Ankle fractures are common injuries and the third most common fragility fracture. In all, 40% of ankle fractures in the frail are open and represent a complex clinical scenario, with morbidity and mortality rates similar to hip fracture patients. They have a higher risk of complications, such as wound infections, malunion, hospital-acquired infections, pressure sores, veno-thromboembolic events, and significant sarcopaenia from prolonged bed rest. A modified Delphi method was used and a group of experts with a vested interest in best practice were invited from the British Foot and Ankle Society (BOFAS), British Orthopaedic Association (BOA), Orthopaedic Trauma Society (OTS), British Association of Plastic & Reconstructive Surgeons (BAPRAS), British Geriatric Society (BGS), and the British Limb Reconstruction Society (BLRS).Aims
