Management of soft tissue tumors of the upper extremity: a review
No full textIntroduction: Management of malignant tumors of the hand and wrist is challenging and is generally approached by limb salvage or amputation. With advances in care, amputation has been superseded by limb salvage as the treatment of choice.
Methods: A narrative literature review was performed to identify articles on the topic of management of soft tissue tumors of the upper extremity, including surgical management, adjuvant radiation therapy, and chemotherapy.
Results: A total of 29 articles were selected. Earlier reports favored radical tumor resection, which often led to amputation, whereas later articles demonstrated limb salvage as the preferential treatment modality.
Conclusions: Given the detrimental effects on function and psychologic outcomes, amputation has been superseded by limb salvage in most cases, although it can occasionally be the only option. A variety of adjuvant therapies have been described, including radiation or brachytherapy, chemotherapy, and regional hyperthermia. Radiation treatment, and specifically brachytherapy, is beneficial to select patients. Controversy surrounds chemotherapy in certain subtypes, and regional hyperthermia requires further investigation
Total hip arthroplasty via the direct anterior approach with Kerboull-type acetabular reinforcement device for an elderly female with factor XI deficiency
No full textWe present a case of successful and uncomplicated total hip arthroplasty with an acetabular reinforcement device in an elderly patient with hip osteoarthritis already diagnosed with factor XI deficiency, which is a very rare bleeding disorder and at high risk of post-operative haemorrhage, and it poses a substantial challenge to surgeons as a consequence of the specific risks of infection and fixation failure. Moreover, bone fragility in elderly patient increases potential risk of adverse event. Fresh frozen plasma was used to supplement factor XI activity. Importantly, transfusion-transmitted disease such as having factor XI inhibitor was promptly surveyed prior to the supplement since the patient had previous history of the administration of fresh frozen plasma. Under prompt and effective peri-operative haemostasis, rigid implant fixation and rigorous attention to the prevention of infection seem to achieve the best possible outcomes for elderly patients with a bleeding disorder undergoing total hip arthroplasty
Gluteal muscle contracture: diagnosis and management options
No full textGluteal muscle contracture (GMC), a debilitating disease, exists all over the globe but it is much more prevalent in China. Patients typically present with abduction and external rotation of the hip and are unable to bring both the knees together while squatting. Multiple etiologies have been postulated, the commonest being repeated intramuscular injection into the buttocks. The disease is diagnosed primarily by clinical features but radiological features are necessary for the exclusion of other pathological conditions. Non-operative treatment with physiotherapy can be tried before surgery is considered but it usually fails. Different surgical techniques have been described and claimed to have a better outcome of one over another but controversy still exists. Based on published literatures, the clinical outcome is exceptionally good in all established methods of surgery. However, endoscopic surgery is superior to conventional open surgery in terms of cosmetic outcome with fewer complications. Nevertheless, its use has been limited by lack of adequate knowledge, instrumentations, and some inherent limitations. Above all, post-operative rehabilitation plays a key role in better outcome, which however should be started gradually
Augmentation of proximal femoral nail in unstable trochanteric fractures
No full textIntroduction: Biomechanically proximal femoral nail (PFN) is a better choice of implant, still it is associated with screw breakage, cut out of screw through femoral head, Z effect, reverse Z effect, and lateral migration of screws. The purpose of this study is to evaluate the results of augmented PFN in terms of prevention of postoperative complications and failure rates in unstable trochanteric fractures.
Material and methods: We carried out a prospective study of 82 cases with unstable trochanteric femoral fractures from April 2010 to December 2015. Forty-two females and 40 males in the age group between 58 and 81 years were included in this study. There were 45 cases of AO 31 A2 (2.2, 2.3) and 37 cases of AO 31 A3 (3.1, 3.2, 3.3). Fractures were fixed by PFN with augmentation by an additional screw from trochanter to inferior quadrant of femoral head or cerclage wire to strengthen the lateral trochanteric wall.
Results: The bone healing is observed in all the cases in the mean period of 14.2 weeks. Nine patients developed complications, including lateral migration of neck screws (n = 5), Z effect (n = 1), infection (n = 2), and breakage of distal interlocking bolt in one case. Removal of screws was required in five cases. Patients were followed up for a mean of 8.4 months. At the end of follow-up the Salvati and Wilson hip function was 32 (out of 40) in 88% of patients.
Conclusion: The stabilization of lateral trochanteric wall with additional screw or cerclage wire increases the stability of construct
Putting 3D modelling and 3D printing into practice: virtual surgery and preoperative planning to reconstruct complex post-traumatic skeletal deformities and defects
No full text3D printing technology has revolutionized and gradually transformed manufacturing across a broad spectrum of industries, including healthcare. Nowhere is this more apparent than in orthopaedics with many surgeons already incorporating aspects of 3D modelling and virtual procedures into their routine clinical practice. As a more extreme application, patient-specific 3D printed titanium truss cages represent a novel approach for managing the challenge of segmental bone defects. This review illustrates the potential indications of this innovative technique using 3D printed titanium truss cages in conjunction with the Masquelet technique. These implants are custom designed during a virtual surgical planning session with the combined input of an orthopaedic surgeon, an orthopaedic engineering professional and a biomedical design engineer. The ability to 3D model an identical replica of the original intact bone in a virtual procedure is of vital importance when attempting to precisely reconstruct normal anatomy during the actual procedure. Additionally, other important factors must be considered during the planning procedure, such as the three-dimensional configuration of the implant. Meticulous design is necessary to allow for successful implantation through the planned surgical exposure, while being aware of the constraints imposed by local anatomy and prior implants. This review will attempt to synthesize the current state of the art as well as discuss our personal experience using this promising technique. It will address implant design considerations including the mechanical, anatomical and functional aspects unique to each case
Learning navigation – Learning with navigation. A review
No full textThe goal of this review paper is to retrieve from the existing literature relevant information (1) about the learning curve of the currently existing navigation systems and (2) about the use of navigation system for teaching orthopaedic procedures. All studies reporting on the learning curve of navigation systems support the hypothesis that computer-navigated total knee arthroplasty (TKA) involves only a short learning curve and that beginners can obtain good results from the beginning of their experience, as navigation provides continuous feedback during all phases of the knee replacement surgery and allows for correcting any bone cut errors. Interestingly, there is no comparable research on the learning curve of TKA with standard, manual instrumentation. One might postulate that this learning curve might be longer than with navigation, with potentially a higher rate of outliers. The current literature does support that navigation may be an efficient teaching tool for both experienced orthopaedic surgeons and trainees. Experienced surgeons may improve their skills with conventional techniques and learn new techniques more efficiently and more quickly. Trainees may have a better understanding of the procedure and learn standard techniques with a shorter learning curve. This is probably due to the immediate feedback of navigation systems. A shorter learning curve may be associated with improved clinical and functional results for the patient during this critical period. However, there is no evidence that training with navigation excludes trainees from the need to work in academic environments with experienced teachers. Future techniques in training may include the development of laboratory simulation procedures using navigated feedback
Primary hemiarthroplasty for treatment of unstable pertrochanteric femoral fractures (AO/OTA Type 31 A2.3) in elderly osteoporotic patients
No full textIntroduction: The aim of this study was to prospectively analyze the role of primary hemiarthroplasty in unstable osteoporotic pertrochanteric fractures (AO/OTA Type 31 A2.3), with emphasis given to postoperative Functional Independent Measure (FIM) and Harris Hip Score (HHS).
Methods: Fifty-six consecutive patients (average age 78.25 ± 5.45), out of which 24 males (79.29 ± 4.99) and 32 females (77.47 ± 5.72), with unstable pertrochanteric femoral fractures, operated with primary hemiarthroplasty procedure from 2012 to 2014 were included in this prospective study with a follow-up of two years. Primary outcomes were FIM and HHS. Secondary outcomes included duration of surgery, estimated intraoperative blood loss, time to first postoperative full weight-bearing, time to walking ability with and without crutches, average hospital stay, postoperative complications, and mortality.
Results: The FIM score at 3 months was 85.9 ± 5.7. HHS at two years was excellent for 41 patients (73, 2%), good for eight (14.3%), fair for four (7.1%), and poor for three (5.4%). The mean duration of surgery was 62.6 min, estimated intraoperative blood loss 175.5 mL, time to first postoperative full weight-bearing 2.2 ± 0.4 days, ability to walk with crutches 6.3 ± 1.8 days and without crutches 44.2 ± 12.7 days, and the average hospital stay was 9.6 ± 2.7 days.
Conclusion: This study highlighted good clinical postoperative outcome scores for primary hemiarthroplasty for the treatment of unstable pertrochanteric femoral fractures in elderly osteoporotic patients. This procedure seems to be secure and effective, and offers a good quality of life in terms of FIM and HHS
Hospital at home – a review of our experience
No full textIntroduction: Hospital at home (HAH) is a service that provides home-based nursing and rehabilitation services whose aim is to prevent admission or to facilitate early discharge from care in an acute hospital.
Methods: We evaluated the effectiveness of early discharge hospital at home (HAH) schemes for hip fracture patients over a 27-year period in a district general hospital in the United Kingdom. A long-term database for audit and research purposes is maintained for all hip fracture patients admitted to Peterborough City Hospital. The data were analysed retrospectively and patients were followed up routinely for six weeks after discharge.
Results: As many as 8876 patients were admitted with a hip fracture between 1st January 1987 and 31st December 2014, of which 5512 patients were eligible for one of the two available HAH schemes. The proportion of eligible patients discharged to the HAH schemes, and their hospital stay and readmission rates were measured; 1786 patients were discharged to a HAH scheme. The proportion of patients discharged to the scheme progressively reduced from a maximum of 94% to a minimum of 13% over the study period. The length of hospital stay until discharge to the scheme progressively increased from a mean of eight days to 18 days.
Discussion: We conclude that HAH schemes can potentially reduce the length of hospital stay of hip fracture patients but continued resources and service organisation have to be provided to match the increasing demand to prevent the service from becoming ineffective
Dual head screw hip nailing for trochanteric fractures
No full textIntroduction: There are limited information and inconclusive results for dual head screw intramedullary hip nails for trochanteric fractures. Therefore, we performed a prospective study to evaluate the healing of fractures, and survival, function, and complications of patients operated with this implant.
Methods: We prospectively studied 79 patients (61 women and 18 men; mean age: 84.7 years; range: 65–96 years) with a low-energy trochanteric fracture, treated with a dual head screw intramedullary hip nail from 2013 to 2016. The mean follow-up was 2.1 years (range: 1–3 years); seven patients were lost to follow up. This left 72 patients for further analysis. We evaluated the healing of fractures, and survival, function, and complications of patients.
Results: Fracture healing was evident in 70 patients (97.2%) at 2–3 months postoperatively. One patient experienced cut-out and z-effect phenomenon of the head screws. Another patient experienced a periprosthetic femoral diaphysis fracture at the distal tip of the nail. A third patient experienced an acute postoperative superficial skin infection that was treated successfully with wound dressing changes and a course of antibiotics. Sixteen patients (22.2%) deceased within 12 months postoperatively. In the remaining patients, the Harris Hip Score (HHS) at 12 months postoperatively was excellent in 16 (28.6%), good in 23 (41.1%), fair in 10 (17.8%), and poor in 7 patients (12.5%). The function declined after the patients’ fracture. Fair and poor results were related to age > 85 years, poor pre-fracture level of function, and AO/OTA-31-A3 fracture types.
Conclusion: The dual head screw intramedullary hip nail is associated with high healing and low complication rates for intertrochanteric fractures. The function of the patients is good or excellent in most cases; however, it declines, especially for those patients with age > 85 years, poor pre-fracture level of function, and AO/OTA-31-A3 fracture types
Arthroscopic treatment of chondral defects in the hip: AMIC, MACI, microfragmented adipose tissue transplantation (MATT) and other options
No full textChondral lesions are currently considered in the hip as a consequence of trauma, osteonecrosis, dysplasia, labral tears, loose bodies, dislocation, previous slipped capital femoral epiphysis and Femoro-Acetabular-Impingement (FAI). The management of chondral lesions is debated and several techniques are described. The physical examination must be carefully performed, followed by radiographs and magnetic resonance imaging (MRI). Differential diagnosis with other pathologies must be considered. Debridement is indicated in patients younger than 50 years with a chondropathy of 1st or 2nd degree. Microfractures are indicated in patients younger than 50 years with a chondropathy of 3rd or 4th degree less than 2 cm2. Matrix-Induced Autologous Chondrocyte Implantation (MACI) and Autologous Matrix-Induced Chondrogenesis (AMIC) procedures are indicated in patients with full-thickness symptomatic 3rd–4th degree chondral defects, extended 2 cm2 or more. The AMIC procedure has the advantage of a one-step procedure and much less expense. Microfragmented adipose tissue transplantation (MATT) is indicated for the treatment of delamination and 1st and 2nd degree chondral lesions, regardless of the age of the patient. Chondral defects are effective when the joint space is not compromised. When the Tonnis classification is two or greater, treatment of chondral lesions should be considered ineffective
