Abstract
BACKGROUND Total knee arthroplasty (TKA) is associated with severe postoperative pain. Multimodal analgesia, including peripheral nerve block, is recommended for post-operative pain relief. Administration of some pain medications prior to surgery has shown to be more effective than after the operation. This is a prospective, randomized controlled trial designed to compare the analgesic efficacy of the adductor canal block (ACB) performed immediately before or immediately after primary total knee arthroplasty (TKA). We hypothesized that ACB before the surgery will reduce postoperative pain and improve knee function. METHODS A total of 50 patients were enrolled and randomized into 2 groups, with 26 patients receiving a preoperative ACB and 24 receiving a postoperative ACB. RESULTS Treatment groups were similar in terms of gender (p = .83), age (p = 0.61) weight (p = .39) and ASA score. Average visual analogue scale (VAS) on arrival to the post-anesthesia care unit (PACU) were 4.9 ± 3.2 in the preoperative ACB versus 3.4 ± 2.8 for the postoperative ACB (p = .075). VAS scores at different time points as well as the mean, minimal and maximal reported VAS scores were not significantly different between the two groups. The cumulative quantities of Fentanyl administered by the anesthesia team was comparable between the groups. Similarly, the dosage of Morphine, Tramadol, Acetaminophen and Dipyrone showed only small variations. The Quality of Recovery Score, Knee Society Scores and knee range of motion did not differ between the groups. CONCLUSIONS Our findings demonstrate no significant differences in patient total narcotics consumption, pain scores and functional scores, between preoperative and postoperative ACB in patients undergoing TKA. TRIAL REGISTRATION The trial was registered at www.clinicaltrials.gov and was assigned the registration number NCT02908711. LEVEL OF EVIDENCE level I randomized controlled trial.

Antibiotic prophylaxis as a quality of care indicator: does it help in the fight against surgical site infections following fragility hip fractures? Arch Orthop Trauma Surg 2022; 142:239-245. [PMID: 33216182 DOI: 10.1007/s00402-020-03682-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2020] [Accepted: 11/04/2020] [Indexed: 01/19/2023]
Abstract
INTRODUCTION Fragility hip fractures are associated with increased morbidity, mortality, and costs. To improve patient care, quality indicator programs were introduced. Yet, the efficacy of these programs and specific quality indicators are questioned. We aimed to determine whether defining prophylactic pre-surgical antibiotic treatment as a quality indicator affected hip fracture outcomes. MATERIALS AND METHODS A retrospective study comparing consecutive patients, 65 years and older, who were operated for fragility hip fractures between 01/01/2011 and 30/06/2016, before and after the prophylactic pre-surgical antibiotic treatment quality indicator, which was introduced in 01/2014. Primary outcomes were 1-year surgical site infections (SSI). Secondary outcomes were meeting the quality index and mortality rates, either within a hospital or during the first post-operative year. RESULTS 904 patients, ages 82.5 ± 7.2 years were operated for fragility hip fractures. 403 patients presented before the antibiotic prophylaxis quality indicator, and 501 following its administration. Patients demographics were comparable. In the pre-quality indicator period, documentation of prophylactic antibiotic treatment was lacking. Only 19.6% had a record for antibiotic administration in their surgical records and for merely 10.4% the type of antibiotic was stated. However, in the post-quality indicator period, 97.0% of patients had a registered prophylactic antibiotic regimen in the hour preceding the surgical incision (p < 0.001). Post-operative SSI rates were equivalent, and as were in-hospital infections, mortality and recurrent hospitalizations CONCLUSIONS: The introduction of the pre-operative antibiotic treatment quality indicator increased the documentation of antibiotic administration yet failed to influence the incidence of post-operative orthopaedic and medical infections in fragility hip fracture patients.

Characteristics and Outcomes of Hip Fracture Patients Hospitalized in an Orthogeriatric Unit Versus an Orthopedic Department: A Retrospective Cohort Study. Geriatr Orthop Surg Rehabil 2021; 12:2151459320986299. [PMID: 33489431 PMCID: PMC7804357 DOI: 10.1177/2151459320986299] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Revised: 11/12/2020] [Accepted: 12/02/2020] [Indexed: 11/18/2022] Open
Abstract
Introduction: Hip fractures are a significant health risk in older adults and a major cause
of morbidity, functional decline and mortality. Our aim was to compare
clinical outcomes of older patients hospitalized in an ortho-geriatric (OG)
unit to those hospitalized in an orthopedic department (OD) for surgical
treatment of a hip fracture. Methods: A retrospective cohort study of hip fractured patients hospitalized between
2015-2016 in a single tertiary university-affiliated medical center.
Included were patients aged 65 and older who had undergone hip fracture
surgery and were admitted to either a geriatric or orthopedic ward. Results: 441 patients met the inclusion criteria (195 in the OG unit, 246 in the OD);
257 were transferred to an affiliated geriatric center hospital (107 from
the OG unit and 127 from the OD) for rehabilitation. Patients in the OG unit
were older, more cognitively and functionally impaired and with more
comorbidities. The 1-year mortality rate was significantly lower in the OD
group (OR 0.32, CI 95% 0.19-0.53, p < 0.001), however, after propensity
matching, the 30-day and 1 year mortality rates were similar in both groups.
No difference was found in the rehabilitation length of stay between the
groups. The functional independence measure improvement was similar in both
groups, with a non-significant trend toward better functional improvement
among OG unit patients. Conclusions: Despite the higher complexity of patients, worse baseline functional capacity
in the OG unit, improvement after rehabilitation was similar in both groups.
These results demonstrate the advantages of the OG unit in treating and
stabilizing frail older adults, thus maximizing their chances for a
successful recovery after hip fractures. Level of Evidence: Level IV

Abstract
INTRODUCTION Holocaust survivors (HS) were under an immense continues physical and mental stressors in their younger years, putting them at increased risk for both fragility hip fractures and worse medical and functional outcomes. We aimed to evaluate whether being a HS could affect the functional outcomes of fragility hip fractures in patients 80 years of age and older following surgery. MATERIALS AND METHODS A retrospective study comparing consecutive patients, 80 years and older, who were operated for fragility hip fractures between 2011 and 2016. HS survival status was self-defined by survivors who were born in European and northern African countries that were later occupied by the Nazi regime during World War II and experienced incarceration in concentration camps, forced labor camps and mass transport. Primary outcomes were mortality either within hospital or in the post-operative year. Secondary outcomes were in-hospital complications, recurrent hospitalizations and orthopedic complications within the post-operative year. RESULTS Two hundred thirty-one HS and 339 controls, ages 86.4 ± 4.4 years who were operated for fragility hip fracture between January 2011 to June of 2016 were included in the study. Patients from both groups were of similar age, Carlson's co-morbidity index score, leaving arrangement and pre-fracture mobility. Among HS there were more women (p = 0.029). HS did not have lower survival rates either within hospital or in the post- operative year. Both length of stay and in-hospital complication rates were similar between groups. In the post-operative year, HS were less likely to be hospitalized than controls (p = 0.021). The rate of orthopedic complications was also similar. CONCLUSIONS Holocaust survivors patients do not achieve worse outcome following fragility hip fracture surgery and present distinctive resilience.

Abstract
BACKGROUND Orthopedic surgeons routinely obtain informed consent prior to surgery. Legally adequate informed consent necessitates a thorough discussion of treatment options and risks and proper documentation. However, the quality of informed consent in orthopedic trauma patients is an under-researched area. PURPOSE To assess the quality of the informed consent process in trauma compared with elective orthopedic patients and to assess patients' emotional state at the time of signing consent form. METHODS Sixty-two consecutive patients undergoing either elective total joint arthroplasty ( N = 32) or orthopedic trauma surgery ( N = 30) were included. The data were collected through personal interviews using a proposed informed consent score. The interviews were held after obtaining the informed consent and before the index procedure. Patients were asked to describe their diagnosis, the surgical procedure, its' benefits, and risks as well as alternative treatments. RESULTS Mean age differed significantly between elective and trauma group patients (66.1 vs. 51.6, respectively, p < 0.01), while gender and education level were comparable ( p = 0.075, p = 0.55, respectively). The quality of consent was significantly better for patients with post-high-school education compared to elementary education level (consent score: 16.9 ± 4.1 vs. 12.2 ± 5.5, p = 0.021). Patients in the elective group showed an overall higher quality of consent, as reflected by a mean score of 17.03 ± 4.2 versus a mean score of only 13.73 ± 4.7 in the trauma group ( p = 0.005, 95% CI: 1.02-5.57). Specifically, trauma patients demonstrated a lower comprehension of the diagnosis, the benefits of surgical treatment, the possible complications, and the expected postoperative course. CONCLUSION Patients undergoing trauma surgery are significantly more likely to have an inadequate understanding of the proposed treatment. These findings raise questions concerning the validity of consent from trauma patients.

Abstract
INTRODUCTION With the aging of the population the rate of fragility hip fractures increases. While medical recommendations are for hasten surgical treatment, for some older patients burdened with severe comorbidities, this might be risky. AIMS To compare the outcomes of patients treated non-surgically to those of the most fragile patients treated surgically. PATIENTS AND METHODS A retrospective cohort study, of individuals aged ≥65 years who presented with fragility hip fractures between 01.01.2011-30.06.2016, to a primary trauma center. Patients treated surgically were stratified according to their age-adjusted Charlsons' comorbidity index (ACCI) score. Patients in the upper third of ACCI score, representing the more fragile population, were compared to patients treated non-surgically. RESULTS 847 patients presented with fragility fractures. 94 (11%) were treated non-surgically and 753 (89%) underwent surgery. Medical reasons were the leading cause for non-surgical treatment (61.7%). Surgically-treated patients were stratified according to their ACCI and 114 patients with ACCI > 9 were chosen for comparison. While both groups were comparable in terms of age, the non-surgical treatment group had more female patients (p. = 0.026) and a smaller proportion of independent walkers (p < 0.001). The ACCI was higher for the surgical treatment group (p < 0.001). In-hospital mortality was similar (14.9% and 18.1% for the operative and non-surgical groups respectively, P. = 0.575). However, one-year mortality was significantly higher for the non-surgical group (48.2% vs. 67.0%, P. = 0.005). The rates of in-hospital complications and 1-year readmissions were similar. CONCLUSIONS Operative treatment for fragility hip fracture reduces long-term mortality rates even in the more fragile patients, compared to non-surgical treatment.

Abstract
PURPOSE To define risk factors for rehospitalization following fragility hip fractures and to create a predictive model. METHODS A retrospective cohort study of patients 65 years and older, who were treated operatively following fragility hip fractures between 01.2011 and 06.2016. Patients were allocated into two study groups based on the occurrence of recurrent hospitalizations in the year following surgery. Demographic information, comorbidities, and in-hospital characteristics were collected, as was information regarding 1-year readmissions. Multivariate analysis of factors predictive of rehospitalizations was performed, followed by a logistic regression using all predictors with p < 0.05. A stepwise backwards elimination method was used to create the predictive model. RESULTS Eight hundred and fifty-one patients were included; 369 (43.4%) had recurrent hospitalizations within the first post-operative year. Patients who were rehospitalized were more likely to be males, to use a walking aid and to live dependently. They had a higher age-adjusted Charlson's comorbidity index (ACCI) score, a higher perveance of atrial fibrillation, lower hemoglobin, worse renal function, less platelets, and longer time to surgery. Prevalence of in-hospital complications was similar. Six variables were found to independently influence the chance for readmissions: male gender, the use of a walking aid, higher ACCI score, lower hemoglobin, atrial fibrillation, and a longer surgical delay. Only the first four were found to be adequate predictors and were added to the prediction formula. CONCLUSION High 1-year readmission rates are seen following discharge in patients with fragility hip fractures. Addressing risk factors might aid to better rehabilitate patients and reduce morbidity.

Morbidity and mortality after fragility hip fracture surgery in patients receiving vitamin K antagonists and direct oral anticoagulants. Thromb Res 2018; 166:106-112. [PMID: 29727737 DOI: 10.1016/j.thromres.2018.04.022] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2018] [Revised: 04/17/2018] [Accepted: 04/20/2018] [Indexed: 11/19/2022]
Abstract
INTRODUCTION Early surgical treatment is recommended to reduce morbidity and mortality in patients with fragility hip fractures. Anticoagulation treatment poses a surgical challenge. While the action of vitamin K antagonists (VKAs) can be reversed, for direct oral anticoagulants (DOACs) antidote is only available for dabigatran. We aimed to assess the outcomes of patients treated with VKAs or DOACs undergoing surgical treatment for fragility hip fractures. MATERIALS AND METHODS A retrospective study of patients presenting with proximal femoral fractures between January 2012 and June 2016. Patients with VKAs received vitamin-K. Primary outcomes were 1-year and in-hospital mortality. Secondary outcomes were time to surgery, in-hospital complications, need for blood transfusions and 1-year readmissions. RESULTS Seven-hundred seventy-nine patients (796 hips) were included; 103 received VKAs, 47 DOACs and 646 no-anticoagulation. No difference between the 3 groups was noted with respect to patients' demographics or surgery type. Charlson's comorbidity index was higher for the DOACs group. Patients under anticoagulation were delayed to theater (Surgery < 48 h in 51% DOACs and 59% VKAs patients vs. 92% of no-anticoagulation, p < 0.001). Neither in-hospital nor 1-year mortality differed between groups. No other outcome measures differed, except for more wound infections in VKAs patients. CONCLUSIONS While preoperative anticoagulation delays surgery following fragility hip fractures, this delay was not found to be related to increased morbidity or mortality. DOACs-treated patients did not have adverse outcomes compared to VKAs-treated patients despite the irreversibility of their treatment.

Fracture-related infection: A consensus on definition from an international expert group. Injury 2018; 49:505-510.

Abstract
Fracture-related infection (FRI) is a common and serious complication in trauma surgery. Accurately estimating the impact of this complication has been hampered by the lack of a clear definition. The absence of a working definition of FRI renders existing studies difficult to evaluate or compare. In order to address this issue, an expert group comprised of a number of scientific and medical organizations has been convened, with the support of the AO Foundation, in order to develop a consensus definition. The process that led to this proposed definition started with a systematic literature review, which revealed that the majority of randomized controlled trials in fracture care do not use a standardized definition of FRI. In response to this conclusion, an international survey on the need for and key components of a definition of FRI was distributed amongst all registered AOTrauma users. Approximately 90% of the more than 2000 surgeons who responded suggested that a definition of FRI is required. As a final step, a consensus meeting was held with an expert panel. The outcome of this process led to a consensus definition of FRI. Two levels of certainty around diagnostic features were defined. Criteria could be confirmatory (infection definitely present) or suggestive. Four confirmatory criteria were defined: Fistula, sinus or wound breakdown; Purulent drainage from the wound or presence of pus during surgery; Phenotypically indistinguishable pathogens identified by culture from at least two separate deep tissue/implant specimens; Presence of microorganisms in deep tissue taken during an operative intervention, as confirmed by histopathological examination. Furthermore, a list of suggestive criteria was defined. These require further investigations in order to look for confirmatory criteria. In the current paper, an overview is provided of the proposed definition and a rationale for each component and decision. The intention of establishing this definition of FRI was to offer clinicians the opportunity to standardize clinical reports and improve the quality of published literature. It is important to note that the proposed definition was not designed to guide treatment of FRI and should be validated by prospective data collection in the future.

Abstract
Amputation of the forefoot is a salvage procedure for several forefoot acute or chronic infection. A good, sensate and durable skin cover is important for quicker and better rehabilitation. The use of filleted flaps (or "spare parts technique") has been published in the past as a creative technique. The purpose of this article is to introduce a reproducible, pre-planned, technique that requires less creativity for the use of the "spare parts". The authors describe a case series of 4 patients with deep infection and osteomyelitis of the forefoot, without involvement of the medial skin that underwent two staged procedure for transmetatarsal amputation with medial forefoot fillet flap. The first procedure was amputation of the 4 lesser metatarsal and the wound was left open. After a few days the second operation was done with amputation of the first metatarsal bone and using the filleted medial skin and subcutaneous tissue for closure of the wound. In conclusion the medial fillet flap is an effective method of covering large wounds after partial, lateral forefoot amputation. This method shortens the healing time of the patient, and in hospital stay. The authors recommend using the staged method when dealing with diabetic patients with partial, central and lateral forefoot deep infection and/or necrosis.

Abstract
INTRODUCTION Hip fractures in the elderly are a major cause of morbidity and mortality. The treatment settings of these patients may change their outcomes. The aim of this study is to compare the outcomes of patients with displaced femoral neck fractures who were admitted to the orthopedic vs. geriatric wards. PATIENTS AND METHODS A retrospective study was conducted on 217 consecutive older patients with 219 displaced femoral neck fractures admitted either to the orthopedic or the geriatric ward between Jan. 2013 and Jun. 2015. Information regarding demographic, medical history, surgical management, hospitalization, and one year readmissions and mortality data was retrieved from electronic charts. RESULTS 102 hemiarthroplasty patients were admitted to the orthopedic ward and 117 to the geriatric ward. Patients' characteristics, including age, living arrangements, mobility status and the Charlson Comorbidity Index were similar between groups. Patients from the orthopedic ward had shorter hospitalization time (9±5.1 vs. 10.8±6.7days, p=0.022) and presented a lower in-hospital complication rates (0.6±0.96 vs. 1±1.9, p=0.022), namely fewer events of urinary retentions, urinary tract infections and pneumonias (8.8% vs. 23.9%, p=0.004, 3.9% vs. 14.5%, p=0.010 and 2.9% vs. 12.2%, p=0.034, respectfully). Readmission rates were similar. Neither in hospital nor one year mortality rates differed between groups. CONCLUSIONS Our study found that geriatric care was not superior to orthopedic directed management in the treatment of elderly patients with hip fractures in terms of in-hospital complications, and hospitalization times.

[BISPHOSPHONATES AS A PREVENTATIVE TREATMENT FOR OSTEOPOROTIC HIP FRACTURES: A MIXED BLESSING]. HAREFUAH 2017; 156:433-437.

Abstract
BACKGROUND The widespread use of bisphosphonates for treating osteoporosis in the last two decades has raised concern about the complication of atypical hip fractures secondary to bisphosphonate treatment. These fractures may be the result of a minor trauma to the hip or without any trauma at all. It may be heralded by prodromal groin or hip pain. Prolonged bisphosphonate treatment and atypical fractures may exist, but the nature and the extent of this linkage are still unknown. Currently, there is a lack of adequate evidence-based methods or a consensus about the treatment of this unique phenomenon. METHODS We retrospectively examined the records of all subtrochanteric hip fracture cases admitted to our department in the years 2010-2014. During that period, we treated a total of 1315 patients:726 patients with pertrochanteric fractures, 514 patients with subcapital fractures and 75 patients with distal subtrochanteric fractures. Among those, 16 patients (1.2%) qualified as atypical hip fractures. The location of the fracture, period of bisphosphonates use, fixation type, complications and recovery were recorded. RESULTS The average age of the patients in our study was 76.9 years. All patients were treated with bisphosphonates and over 80% of the patients were treated specifically with Alendronate prior to the fracture. Mean treatment time was 7.8 years. Most of the fractures (75%) were subtrochanteric, and the others were at the femur midshaft. All patients received surgical fixation and all accomplished union of the fractures. CONCLUSIONS It seems reasonable to assume a causative relationship between a long term use of bisphosphonates and the occurrence of atypical hip fractures. It is a relatively rare complication; nevertheless, it should be kept in mind during a long term use of bisphosphonates. According to our department's clinical experience we found no delay in bone union with these atypical hip fractures. It seems reasonable to prophylactically fixate atypical stress fractures before they become a full fracture.

The value of 18-FDG PET/CT in the diagnosis and management of implant-related infections of the tibia: a case series. Injury 2015; 46:1377-82.

Abstract
BACKGROUND Positron emission tomography (PET) combined with Computerised Tomography (CT) is gaining ground in clinical settings due to its added value of combined metabolic and anatomical imaging. PET/CT has shown promising results in diagnosing both acute and chronic infection of the axial and appendicular skeleton. PET imaging has an advantage in patients with metallic implants because FDG uptake, in contrast to magnetic resonance imaging (MRI) and standard computed tomography (CT), is not hampered by metallic artifacts. The role of PET/CT in the evaluation of implant-related infections involving the tibia in particular has not been thoroughly studied. PURPOSE To investigate the usefulness of 18-FDG PET/CT in the diagnosis and treatment of implant-related infections of the tibia following osteosynthesis. METHODS We reviewed 10 patients who underwent internal fixation to the tibia following trauma (4 open fractures, 6 closed fractures) and presented later with clinical signs of a possible implant-related infection. In evaluating the patients we used standard work-up methods (standard radiographs, lab tests) as well as advanced imaging techniques (PET/CT) in order to confirm the diagnosis and decide upon the preferred treatment. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were then calculated for PET/CTs ability to predict presence of infection using intraoperative cultures as the gold standard. RESULTS PET/CT validated our working diagnosis 9 out of 10 patients. In particular, it helped distinguish between: infected nonunion (n=4), aseptic nonunion (n=1), soft tissue infection (n=2) and chronic osteomyelitis (n=3). The overall sensitivity and specificity of PET/CT for identifying an osseous infection were 85.7% and 100%, respectively. The PPV and NPV were 100% and 75%, respectively. CONCLUSION PET/CT is a promising imaging modality that can aid in the work up of patients with suspected implant-related infections of the tibia following osteosynthesis, and may be used as a supportive measure in clinical decision making.

Abstract
This article describes an extensile surgical exposure to the distal humerus that is suitable for complex fractures involving the articular surface and extending into the humeral diaphysis proximal to the radial nerve. This method combines 2 approaches: olecranon osteotomy and the lateral paratricipital approach. This combination allows an appropriate exposure of both the articular surface and the humeral diaphysis up to the level of the deltoid tuberosity, while maintaining the extensor mechanism unharmed.

Abstract
BACKGROUND Many factors contribute to suboptimal results after total knee arthroplasty (TKA) but little is known regarding the value of postsurgical rehabilitation after TKA. We examined the effects of an enhanced closed kinematic chain exercises program (AposTherapy) on gait patterns and clinical outcomes among patients with a lack of progress in their postsurgical rehabilitation. METHODS Twenty-two patients were prospectively followed during the study. Gait spatiotemporal parameters were measured at the initial evaluation, after 15 minutes of therapy, and after 3 months of therapy. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the short form (SF) 36 health survey were completed by patients before treatment and after 3 months of treatment. RESULTS The WOMAC and SF-36 scores improved significantly after 3 months of treatment. Gait velocity, single limb support, and step length of the operated leg improved significantly even after a single 15 minutes treatment. Normal gait velocity was observed in 36% of patients after 3 months of treatment. CONCLUSIONS A physiotherapy program that included enhanced closed kinematic chain biomechanical therapy was beneficial for patients who experienced a suboptimal rehabilitation course after TKA.

Abstract
The term posterolateral rotatory instability (PLRI) was coined in 1991 by O'Driscoll to describe the instability of the elbow caused by injury to the lateral ulnar collateral ligament (LUCL). This condition, which is usually preceded by a traumatic dislocation of the elbow, is the most common type of chronic instability of the elbow. In this type of instability, the radius and ulna rotate externally in relation to the distal humerus, leading to posterior displacement of the radial head relative to the capitellum. lateral elbow pain, clicking, popping and snapping are possible symptoms. The diagnosis of PLRI relies on a high index of suspicion and on a detailed physical examination. Several tests have been described including apprehension tests and examination under anesthesia. Surgical treatment with reconstruction of the lateral collateral ligament complex yields successful results. In this review we summarize the current knowledge of the pathoanatomy, presentation, physical examination, diagnostic tests and management of chronic posterolateral rotatory instability of the elbow.

Abstract
Metastases in the proximal femur and in the femoral diaphysis are usually treated with either cephalomedullary or intramedullary nailing. The benefit of curettage and augmentation of the nail with methyl methacrylate remains controversial. The authors retrospectively studied the outcomes with cephalomedullary and intramedullary nailing without curettage and methyl-methacrylate augmentation for lytic metastases of the proximal/diaphyseal femur. Twenty-one complete (11) or impending (10) pathological fractures in 19 consecutive patients were treated between January 2006 and August 2013. There were 11 women and 8 men. Their mean age was 62 years (range, 38 to 87). All patients received adjuvant chemotherapy or radiotherapy.The average postsurgical survival was 9.7 months (range 1-36 months). A single deep infection was debrided. Seventeen out of 19 patients were ambulatory, with or without a walking aid. No implant failure was noted. In other words, patients succumbed to the disease prior to hardware failure. Femoral nail insertion without curettage and cement augmentation provided satisfactory stabilization of proximal and diaphyseal femur fractures, impending or complete, even when there was massive bone destruction.

Abstract
BACKGROUND Bisphosphonates reduce the overall risk of fractures among patients with osteoporosis, and this beneficial effect is long-lasting. However, since bisphosphonates inhibit bone remodeling, they may enhance the formation and propagation of micro-cracks over time and patients may therefore be prone to atypical fatigue fractures, mainly in the subtrochanteric region and femoral shaft. OBJECTIVES To present two cases of subtrochanteric fractures related to bisphosphonate treatment, and review the current literature. CONCLUSIONS Despite the overall beneficial effect of bisphosphonates, further research is required to prevent this significant complication.

Abstract
BACKGROUND Guided growth is most commonly utilized about the knee and ankle for the correction of coronal-plane deformities by the use of plates positioned perpendicular to the physis. Sagittal-plane deformity correction has been described as well. The purpose of our study was to examine the ability to affect axial-rotational growth. Our hypothesis was that placement of plates in an oblique orientation relative to the physis can induce rotational growth deformity. METHODS Our hypothesis was tested with use of a mathematical model and a bone model and subsequently in a rabbit model. Thirteen six-week-old rabbits underwent a rotational guided growth procedure involving the distal aspect of the right femur, with a sham procedure performed on the left side. Two plates were positioned in an oblique orientation relative to the physis, medially and laterally, to guide either internal or external rotational growth. After the rabbits were killed six weeks after the surgery, the femoral rotational profile was assessed by computed tomography scans of the dissected femora and the growth plates were examined histologically. RESULTS A significant effect on the rotational profile was found in the treated femora. When the plates were positioned to guide external rotation, the rotational profile was significantly greater in the treated femora (29.0° compared with 11.3° in the sham femora; p = 0.008). There was a positive linear correlation between the right-left difference in rotational profile and the change in inter-plate angle (R2 = 0.72, p = 0.001). Every 1° of inter-plate angle change induced 0.367° of rotational profile difference (p = 0.001). Histologically, a swirling effect of the physeal cell columns was seen in the treated femora. CONCLUSIONS Guided growth using plates was demonstrated to alter axial-rotational growth in a predictable fashion in a rabbit model. CLINICAL RELEVANCE Guided growth using plates may be effective for correction of rotational and multiplanar deformities.

Abstract
Total hip arthroplasty (THA) using minimally invasive surgery (MIS) can result in soft tissue damage during the trial reduction and actual implantation. We present a surgical technique that reduces soft tissue trauma and facilitates implant reduction while protecting the prosthetic head from scratching during MIS THA. Primary THA using MIS was performed in 16 hips through a transgluteul direct lateral approach. Average follow-up was 54 months (range 52-58 months). At latest follow-up there was no evidence for component dissociation or loosening in any of the patients. Reverse assembly of THA components is a viable option, which may facilitate MIS THA and decrease soft tissue trauma.

Abstract
BACKGROUND The purpose of the study was to examine the effect of a foot-worn biomechanical device on the clinical measurements and gait patterns of patients with total hip arthroplasty (THA). METHODS Nineteen patients, up to 3 months post-THA, were enrolled to the study. Patients underwent a computerized gait analysis to calculate spatiotemporal parameters and completed the Western Ontario and McMaster Universities osteoarthritis index and the SF-36 health survey. Patients then began therapy with a non-invasive foot-worn biomechanical device coupled with a treatment methodology (AposTherapy). Patients received exercise guidelines and used the device daily during their regular activities at their own environment. Follow-up examinations were conducted after 4, 12, and 26 weeks of therapy. Repeated measures ANOVA was used to evaluate changes over time. The clinical significance of the treatment effect was evaluated by computing the Cohen's effect sizes (ES statistic). RESULTS After 26 weeks of therapy, a significant improvement was seen in gait velocity (50.3%), involved step length (22.9%), and involved single limb support (16.5%). Additionally, a significant reduction in pain (85.4%) and improvement in function (81.1%) and quality of life (52.1%) were noted. CONCLUSIONS Patients following THA demonstrated a significant improvement in gait parameters and in self-assessment evaluations of pain, function, and quality of life. We recommend further RCTs to examine the effect of this therapy compared to other rehabilitation modalities following THA and compared to healthy matched controls.

Abstract
INTRODUCTION Total hip replacement has been established as a valid treatment option for displaced subcapital fractures. However, insufficient primary fixation may be the reason for early loosening in these osteoporotic patients. Primary fixation of the cup is usually achieved by press-fit fixation that can be enhanced using screws. Locking the screws into their respective cups may seem to improve the primary fixation of the construct, as locked plates proved superior fixation for osteoporotic fractures. METHODS The study consisted of three groups: in each group, three cups were fixed into blocks of foam bone using press-fit technique. In the first group, no additional screws were used, in the second group two standard screws were inserted, while in the third group two acetabular screws were cemented into the cup to simulate locked screw fixation. Load was applied onto the rim of the acetabular component to cause shearing between the cup and the block. Cup fixation was examined by a loading machine that acquired load versus displacement. The stiffness (load vs. displacement) was calculated. RESULTS Screws, either locked or non-locked, enhanced cup fixation by 26 % (p value <0.01). No significant changes were found between the locking and non-locking screws groups. DISCUSSION These experimental results indicate that acetabular screws enhance primary cup fixation. This may become significant in conditions where the acetabular bone stock is suboptimal, such as when performing total hip arthroplasty after displaced subcapital fractures. However, there is no superiority for locked screws over standard screw fixation.

Abstract
BACKGROUND Intraarticular injections for the local treatment of osteoarthritis are widely used in the office or hospital setting. Septic arthritis is a potential catastrophic complication of intraarticular injection, as bacterial arthritis of any cause is associated with up to 15% mortality and residual impairment of joint function in up to 50% of survivors. There is lack of evidence regarding the precautions that should be taken to avoid such a complication, as well as how often it is encountered. OBJECTIVES To report our experience with the clinical presentation, diagnosis and treatment of knee septic arthritis following intraarticular injections. METHODS We followed six patients who were admitted to the hospital and underwent surgery for the treatment of pyogenic arthritis following injection to the knee joint in outpatient clinics. RESULTS All but one patient were over 70 years old with comorbidities. Three patients were injected with steroid preparations and three with hyaluronic acid several days before admission. In all six patients the infection was treated surgically and three of them had undergone more than one operation during their hospitalization. Four of the six patients were treated by means of an open arthrotomy and synovectomy, and the other two were treated successfully with arthroscopic lavage and synovectomy. One patient underwent an above-knee amputation due to septic shock and died after several days. CONCLUSIONS Despite the rarity of this complication, surgeons must be aware of the possibility of pyogenic arthritis when administering injections, especially in elderly patients with serious underlying medical conditions.

Abstract
Hip replacement is one of the most successful orthopedics' procedures in terms of restoring quality of life. In the past, indications for hip replacement were restricted to elderly people, but nowadays advances in bioengineering technology have driven development of hip implants with less wear and loosening and therefore with longer longevity. Early wear and loosening as well as stress shielding and bone preservation are considered as major issues especially when dealing with young patients. The main reason for this is the fact that younger patients might require one or more hip revision procedures during the course of their life due to their age and high activity level. Especially in young patients it could be an advantage to use primary implants that are more bone preserving and allow more physiological load transfer which cause no or minimal stress shielding at the proximal femur. The two options which exist today are hip resurfacing which preserves the femoral head and various short stem prostheses which transfer the forces in the femur more proximally and more physiologically. This review looks at the options which are available today in bone preserving hip arthroplasties.

Abstract
BACKGROUND Forefoot surgery is often performed under regional anesthesia in awake patients, using tourniquet or Esmarch bandage to obtain a bloodless field. The purpose of this study was to examine the value and need for local tourniquet pain control using local subcutaneous analgesic mixture in patients undergoing forefoot surgery under ankle block anesthesia. MATERIALS AND METHODS We prospectively randomized 56 patients who underwent forefoot surgery under ankle block to receive either subcutaneous local anesthetic mixture under the tourniquet or no additional anesthetic. We checked for local tourniquet pain score (VAS 0 to 100) and skin condition during and after the procedure. RESULTS The tourniquet was quite tolerable in both groups, with an average VAS score of 7 to 21. No difference was observed between groups throughout most of the procedure. No correlation between VAS scores and procedure length or patient's age or gender was found. CONCLUSION An ankle tourniquet was well-tolerated by patients without need for local anesthetic beneath the cuff.

Abstract
Femoroacetabular impingement is the abutment between the proximal femur and the rim of the acetabulum. It is a common cause of labral injury that has been identified as an early cause of hip osteoarthritis. The diagnosis of femoroacetabular impingement of the hip is currently well defined in orthopedic surgery but should attract the attention of physicians in other disciplines. Conversely, much less is known about the etiology and natural history of femoroacetabular impingement.The goal of this study was to assess the number of articles published on femoroacetabular impingement over 11 years in orthopedic vs nonorthopedic medical journals, and to evaluate the quality of available evidence. PubMed and OvidSP databases were searched for articles on femoroacetabular impingement published from 1999 to 2009. Articles were characterized by publication type and journal type per year. Regression analysis was used to determine the effect of publication year on number of publications of each type. The search yielded 206 publications on femoroacetabular impingement during the evaluation period. Seventy-two percent were published in orthopedic journals. Overall, the number of publications increased exponentially with time. There was an increase in clinical trials over the course of the study period. However, studies with high-quality evidence were scarce. The increase in data from orthopedic and nonorthopedic disciplines is welcome. Nevertheless, high-quality evidence on femoroacetabular impingement is lacking. We believe the current trend toward evidence-based orthopedic surgery will impact future research on this relatively new disorder.

Abstract
BACKGROUND Gunshot wounds impose a continuous burden on community and hospital resources. Gunshot injuries to the extremities might involve complex soft tissue, bone, vascular, musculotendinous, and nerve injuries. A precise knowledge of anatomy is needed to evaluate and treat those injuries. OBJECTIVES To review our experience with gunshot wounds to the extremities. METHODS We retrospectively reviewed all civilian cases of gunshot wounds to the limbs treated in our institution during 2003-2005. Altogether, we evaluated 60 patients with 77 injuries. RESULTS Of the 60 patients 36 had fractures, 75% of them in the lower extremity and 81% in long bones. The most common fixation modality used was external fixation (33%), followed by intramedullary nailing (25%). This relatively high percentage of fracture treated with external fixation may be attributed to the comminuted pattern of the fractures, the general status of the patient, or the local soft tissue problems encountered in gunshot wounds. About one-fifth of the fractures were treated by debridement only without hardware fixation. We treated 10 vascular injuries in 8 patients; 6 of them were injuries to the popliteal vessels. Fractures around the knee comprised the highest risk factor for vascular injuries, since 5 of the 12 fractures around the knee were associated with vascular injury requiring repair or reconstruction. There were 13 nerve injuries (16.8%), most of them of the deep peroneal nerve (38%). Only three patients had concomitant nerve and vascular injuries. The overall direct complication rate in our series was 20%. CONCLUSIONS To successfully treat complex gunshot injuries a team approach is necessary. This team should be led by an orthopedic surgeon knowledgeable in the functional anatomy of the limbs.

Abstract
BACKGROUND Unicompartmental knee replacement has become a surgical alternative for treating isolated medial or lateral osteoarthritis of the knee or avascular necrosis of the femoral condyls. OBJECTIVES To evaluate the short-term results of the Oxford Phase 3 unicompartmental knee replacement for unicompartmental knee arthrosis or avascular necrosis of the medial femoral condyle. METHODS During the period 2003-2005 a total of 59 patients (59 knees) underwent medial Oxford Phase 3 unicompartmental knee replacement in our unit. The patients were interviewed and examined, and standing anteroposterior and lateral X-rays were taken. All patients completed the Western Ontario and McMaster Universities Index of Osteoarthritis and the Short Form 12 questionnaire, and the International Knee Society score was evaluated. The data were collected and statistical analysis was performed. RESULTS X-rays were performed and scores for the WOMAC and IKS were assessed for 42 patients (31 females, 11 males). At an average of 32 months after surgery the total WOMAC score was 30. The mean SF-12 physical score was 38 and the mean SF-12 mental score was 51. The mean IKS score was 166. Ninety-one percent of the patients had active flexion of 120 degrees or more. Of 59 knees 7 were converted to total knee arthroplasty--all of them within the first 2 years of starting the procedure and all of them in relatively young patients. CONCLUSIONS Despite the higher revision rate to TKR in this study, our findings confirm the short-term results reported in other studies of the Oxford medial unicompartmental knee and our early failure rate could be explained by a performance learning curve. This study confirms that this bone-preserving procedure should be considered in end-stage isolated unicompartmental osteoarthritis or avascular necrosis by surgeons who have the adequate training and experience.

Abstract
BACKGROUND Pelvic fracture poses a complex challenge to the trauma surgeon. It is associated with head, thoracic and abdominal injuries. As pelvic fracture severity increases so does the number of associated injuries and the mortality rate. OBJECTIVES To report our experience in the treatment of pelvic fractures. METHODS Between October 1998 and September 2001, 78 patients with pelvic fractures were admitted to our hospital. The age range of the 56 male and 22 female patients was 16-92 (mean 42 years). The cause of injury was road accident in 52 patients, fall from a height in 15, a simple fall in 9, and gunshot wounds in 2 patients. The Glascow Coma Scale score on arrival at the hospital was 3-15 (average 12). Twenty-five patients (32%) were admitted to the intensive care unit, 38 (48%) to the orthopedic department, 5 (6.4%) to neurosurgery and the remainder to a surgical department. RESULTS Twenty-six patients (33.3%) received blood transfusion in the first 24 hours. Of the 25 patients with associated head trauma, 6 had intracranial bleeding (32%); 29 patients (37%) had associated chest trauma, 28 (35.9%) had associated abdominal trauma, 16 (20.5%) had vertebral fractures and 40 (51.2%) had associated limb fractures. Pelvic angiography was performed in 5 patients (6.4%), and computed tomography-angiography of the cervical arteries and chest was performed in 1 and 5 patients respectively. Overall, a CT scan was performed in 56 patients (71.8%), of whom 25 (32%) had a pelvic CT on admission. Injury Severity Score was 4-66 (median 20). Laparotomy was performed in 14 patients (18%), spinal fusion in 5 (6.4%), limb surgery in 16 (20.5%), cranial surgery in 4 (5.02%), pelvic surgery in 10 (12.8%), chest surgery in 3 (3.85%), and facial surgery in 2 patients (2.56%). Seven patients (9%) died during the course of treatment. CONCLUSIONS Pelvic fracture carries a high morbidity rate. Associated chest, abdomen and limb injuries are often encountered. A multidisciplinary approach is needed to improve survival and outcome in patients with pelvic fractures.

Abstract
Treatment of osteosarcoma (OSA) of the proximal humerus poses many difficulties and challenges to the treating team. Between 1993 and 2000, we treated 11 patients (three women, eight men; age range, 17-74 years) suffering from OSA of the proximal humerus by 'composite': massive allografts and long humeral prosthesis. At presentation, 10 patients were at stage 2-B and one at stage 3-B of OSA. One patient presented with a pathologic fracture. All patients except patient No. 6, received preoperative chemotherapy followed by limb salvage surgery and postoperative chemotherapy.Surgical margins were graded as wide in all patients. Postoperative complications included non-union at the allograft/host junction (which united after auto grafting) and superficial wound infections that resolved after antibiotic therapy. All surgical procedures were performed by a team headed by an orthopedic oncologist and shoulder surgeon. At latest follow-up (December 2001) all patients, with the exception of one (who was at stage 3-B at presentation) were alive, and had good function of the upper limb. It is our opinion that the team approach comprising an orthopedic oncologist and shoulder surgeon greatly contributed to the good surgical outcome, and hence the good survival and functional results of the patients. Bone allograft offers a modular malleable durable solution to the resected bone segment.

Abstract
BACKGROUND Retroperitoneal abscess is a rare complication of normal labor and delivery, and no apparent etiology is evident. CASES We report on two patient who presented with back and leg pain soon after normal deliveries. While the condition was initially clinically misdiagnosed, ultrasonography and computed tomography demonstrated retroperitoneal collections and aided in guided percutaneous drainage. After a protracted course of antibiotic treatment and daily irrigation, the collections resolved. CONCLUSION Ultrasonography and computed tomography were invaluable in the diagnosis and guided drainage of rare psoas abscesses complicating delivery.

Abstract
We describe a case of stress fracture of the proximal femur occurring in a patient after removal of an internal fixation device for a comminuted subtrochanteric fracture. The presenting clinical picture resembled a late postoperative infection with a positive technetium and gallium bone scan and normal radiological findings. The stress fracture occurred after removal of the fixation device when the patient started full weight-bearing. The patient was treated initially as having osteomyelitis until a second X-radiograph some weeks later demonstrated a stress fracture through one of the previous screw holes. This case illustrates well the possible complication of a insufficiency fracture subsequent to the occurrence of stress risers through screw holes in a weakened bone when submitted to normal load. The clinical presentation may sometimes resemble late postoperative infection.

Abstract
Ankle pain after uncomplicated ankle fractures poses a diagnostic and therapeutic challenge, especially in joints that exhibit insignificant radiographic changes. Ankle joint arthroscopy has become an important diagnostic and therapeutic tool for such cases. Adhesion of the distal tibiofibular syndesmosis, as yet an undescribed entity, was found to be the cause of chronic ankle pain in 11 of 19 patients suffering from chronic ankle pain after an uncomplicated fracture of the ankle. Symptoms resolved after arthroscopic resection of the adhesions in all 11 patients. Arthroscopy has an important role in diagnosis and management of unexplained ankle pain after a seemingly uncomplicated fracture.

Abstract
Snapping of tendons is a well-described entity in the literature, occurring mostly in athletes around the hip, ankle, shoulder, and elbow, but rarely the knee. A case of snapping of the biceps femoris tendon (BFT) in a patient with a painful knee and no history of trauma is described. An abnormal anterior insertion of the BFT was found to be the cause of the pain and snapping. Surgical treatment, reinsertion of the tendon in its anatomic position, completely corrected the abnormality, whereas conservative treatment failed.

Chevron osteotomy in the treatment of hallux valgus. THE JOURNAL OF FOOT SURGERY 1991; 30:276-8. [PMID: 1875004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 12/29/2022]
Abstract
Fifty patients who underwent 80 chevron osteotomies for symptomatic hallux valgus were re-examined and assessed 4 years and 7 months (average) after surgery. Forty-five of the patients were satisfied with the result of their surgery, three patients suffered recurrence of their deformity and two had continuance of their symptomatology. The major complications noted were intraoperative intra-articular fracture of the metatarsal head in five feet, loss of initial repair in three feet, and tilt of the distal fragment (metatarsal head) in two feet. The Chevron osteotomy is a relatively simple procedure that corrects the varus deformity of the first metatarsal, realigns the valgus orientation of the metatarsal head, corrects the hallux valgus deformity, and improves symptomatology.

Abstract
Osteochondritis of the sesamoids of the hallux is an infrequently presenting condition of uncertain etiology. The diagnosis is usually established by the typical clinical presentation, fragmentation of the affected sesamoid seen on the axial-view radiogram and increased uptake on the 99mTc bone scan. The condition is usually refractory to conservative treatment and is best treated by excision of the affected sesamoid.
