Proximal tibia stress fracture with Osteoarthritis of knee − Radiological and functional analysis of one stage TKA with long stem
No full textIntroduction: Proximal tibia stress fractures with knee osteoarthritis pose a challenging situation. We evaluated the radiological and functional outcome of one-stage total knee arthroplasty (TKA) and long stem for patients with varied grades of knee arthritis and proximal tibia stress fractures.
Methods: We analysed 20 patients from April 2012 to March 2017 with proximal tibia stress fractures associated with knee osteoarthritis of varied grades. Out of 20 patients, five were acute fresh fractures. The mean age was 64 years (range, 52–78) which includes three men and 17 women. Previous surgery in the same limb, rheumatoid arthritis, valgus deformity were excluded. All patients were treated with posterior stabilised TKA with long stem, of which, four patients had screw augmentation for medial tibial bone defect and two patients with malunited fracture at stress fracture site required osteotomy, plating and bone grafting. Two patients had two level stress fracture of tibia in the same leg.
Results: The mean follow-up period was 28 (range, 6–60) months. The mean tibiofemoral angle improved from 18.27° varus to 1.8° valgus. The mean knee society score improved from 21.9 (range, −10 to 45) to 82.8 (range, 15–99) [p < 0.05]. The mean Knee Society functional score improved from 15.5 (range, −10 to 40) to 76.8 (range, 10–100) [p < 0.05]. All fractures got united at the last follow-up. One patient had infection and wound dehiscence at six months for which debridement done and had poor functional outcome.
Conclusion: TKA with long stem gives excellent outcome, irrespective of severity of arthritis associated with stress fracture. By restoring limb alignment and bypassing the fracture site, it facilitates fracture healing. Early detection and prompt intervention is necessary to prevent the progression to recalcitrant non-union or malunion
Current paediatric orthopaedic practice in hereditary multiple osteochondromas of the forearm: a systematic review
No full textIntroduction: This systematic review aims to answer three research questions concerning the management of hereditary multiple osteochondromas of forearm in children: What is the best available evidence for the currently employed surgical procedures? What patient characteristics are associated with better prognosis? What disease characteristics are associated with better prognosis?
Methods: We searched the literature using three major databases with no publication date restrictions. To enhance search sensitivity and maintain precision we used keywords/subject terms correlating with patient population, problem and interventions. We used strict inclusion/exclusion criteria to improve validity evidence.
Results: The search process yielded 34 eligible studies with a total of 282 patients (315 forearms). We comprehensively analysed study and patient demographics and interventions and outcomes. Eleven studies (32%) had a long-term follow-up and 31 studies (91%) were retrospective. Of the total number of forearms, ulnar lengthening +/− associated procedures was used in 210 forearms (66.7%), isolated osteochondroma excision in 65 forearms (20.6%) and isolated distal radius hemiepiphysiodesis in 15 forearms (4.7%) among others.
Discussion: Ulnar lengthening can restore radiologic anatomy, improve appearance and to a lesser extent objective clinical parameters like joint range of motion on the short/intermediate term. Isolated osteochondroma excision can relief pain and satisfy cosmetic concerns occasionally. There is poor evidence to suggest that surgery improves quality of life or function. Predictors of surgical success in regard to patient and disease characteristics remain elusive. Natural history and prospective randomized control studies where the control group receives no treatment should be rethought. They have the potential for bias control and identification of the ideal surgical candidate. The complex interplay between the confounding variables has undermined the capability of most studies to provide well-grounded evidence to support and generalize their conclusions. Valid quality of life scales should supplement objective outcome measures
Preoperative ultrasound to identify distribution of the lateral femoral cutaneous nerve in total hip arthroplasty using the direct anterior approach
No full textIntroduction: Recently, the branching pattern of the lateral femoral cutaneous nerve (LFCN) named Fan type has been reported that LFCN injury cannot be avoided in surgical dissections that use the direct anterior approach to the hip joint in the cadaveric study. We hypothesized that the Fan type can be identified by ultrasound The aim of this study was to investigate whether LFCN injury occurs in DAA-THA in cases identified as the Fan type based on preoperative ultrasound of the proximal femur.
Methods: Ultrasonography of the proximal femur on the surgical side was performed before surgery and the LFCN distribution was judged as the Fan type or Non-Fan type. A self-reported questionnaire was sent to the patients at two months after surgery, and the presence or absence of LFCN injury was prospectively surveyed.
Results: After application of exclusion criteria, 45 hips were included. LFCN injury was observed after surgery in 9 of the 10 patients judged as the Fan type based on the ultrasound of the proximal femur (positive predictive value: 90%), and no LFCN disorder was actually observed in 25 of the 26 patients judged as Non-Fan type (specificity: 96.2%).
Conclusions: To prevent injury of the LFCN in patients judged as the Fan type on the ultrasound test before surgery, the risk of direct injury of the LFCN may be reduced through the approach in which an incision is made in the fascia which is opposite to the radial spreading, i.e., between the sartorius and tensor fasciae latae muscles or slightly medial from it
Percutaneous screws CT guided to fix sacroiliac joint in tile C pelvic injury. Outcomes at 5 years of follow-up
No full textIntroduction: The treatment of the sacroiliac joint (SIJ) vertical instability is a matter of current discussions and remains controversial. The aim of our study is the evaluation of the surgical management of SIJ vertical instability involving the use of cannulated screws introduced under CT guidance and local anesthesia.
Materials and methods: In the set time frame of 7 years, 96 poly-trauma patients with Tile's type C fracture of the pelvis with vertical instability of the SIJ were treated. The average distance between the two stumps was 73.4 mm (range: 43–100 mm). All patients were treated with anterior stabilization and subsequent stabilization with cannulated screws (Asnis® Stryker® 6 mm, an average length of 70 mm; range from 55 to 85 mm) of the sacroiliac fracture. The clinical and radiological follow-up was performed with follow-up plain radiograph and Majeed score (from 1 to 60 months after injury).
Results: The consolidation of pelvic fractures was obtained after an average of 63 days. The average Majeed score was as follows: 96 points at 1 month, 84 points at 3 months, 62 points at 6 months, 44 points at 12 months, 42 points at 24 months, 32 points at 36 months, 28 points at 48 months and 28 points at 60 months. Complications were as follows: not fatal deep vein thrombosis in five cases, skin infection at the entry point of the screws in six cases, screw breakage in one case and loosening of the screws in one case. Radiological evidence of fracture consolidation was achieved on average at 63 days. Forty-seven patients managed to get back to their pre-trauma employment at the end of the convalescence period.
Conclusions: Our results suggest that the stabilization of SI Tile type C fracture/dislocations with CT-guided percutaneous cannulated screws is a valid and feasible management option and associated with a low complication rate
Characteristics of the patients with delaminated rotator cuff tear
No full textPurpose: The purpose of this study was to analyze factors relating to delamination in full-thickness rotator cuff tears.
Methods: 126 patients with full-thickness rotator cuff tears treated by arthroscopic rotator cuff repair were the subjects of this study. There were 52 females and 74 males whose average age was 64.2 years. Fifty-three patients had history of trauma. The average duration of disorder was 29.5 weeks. Nineteen patients were diagnosed with diabetes. On types of the tears, small tear was observed in 59 patients, medium tear in 47 patients, large tear in 6 patients, and massive tear in 14 patients. The average size of tear was 1.98 cm. Delamination of the torn cuff was observed in 45 patients. Factors compared between the patients without delamination and those with delamination were as follows: gender and age of the patients, history of trauma, duration of disorder, diabetes, smoking, size and number of rotator cuff tears.
Results: The delamination rate of the smoking patients was significantly higher than non-smoking patients. The delamination rate of patients with more than two tendon tears was significantly higher than those with only one tendon tear. The average size of tear with delamination was significantly larger than that of tear without delamination. The other factors were not related to delamination.
Conclusions: This study suggests that smoking, size of tear and number of torn cuffs are associated with delamination. The progression of torn cuff, anatomical features and nicotine of smoking affect the causes of delaminated tear of rotator cuff
Tuberculous lumbar spinal epidural abscess in a young adult (case report)
No full textIntroduction: Spinal Epidural abscess (SEA) is an uncommon pathology that needs an urgent intervention to decompress the pressure on the spinal epidural sac, cord, and roots. The authors report a rare case of a young adult with lumbar spinal epidural tuberculous abscess occupying the spinal canal from L2–L5 vertebrae with extesion to the posterior paraspinal muscles and presenting with bilateral progressive lower limb weakness.
Case report: A 42 years old male teacher presented with a 15-day history of progressive difficulty to walking and bilateral lower limb weakness associated with fever, malaise and later on urinary incontinence. A magnetic resonance imaging (MRI) scan revealed a paraspinal intermuscular abscess and an abscess occupying the spinal canal compressing the dural sac from L2–L4/5, without any signs of vertebral involvement. Surgery was done by a posterior midline incision. Pus was evacuated from multiple pockets through the paraspinal muscle layers. Laminectomy for L3/4, and hemilaminectomy for L2/3, and L4/5 were performed. Pus and bone specimens were negative for acid-fast bacilli. However, both histopathological studies and Polymerase Chain Reaction (PCR) testing confirmed the presence of tuberculosis (TB). The patient received TB antibiotics, and a follow-up MRI scan at 2 months showed complete evacuation of the abscess. However, signs of L5 spondylitis were evident. No further surgery was needed as there was no vertebral collapse or neural compression and the patient's clinical condition was improving. He had normal right lower limb power and sensation and grade 4+ motor power of the left lower limb. Bowels and bladder function was normal.
Conclusion: Isolated tuberculous spinal epidural abscess is a rare disease and should be treated urgently with evacuation and decompression. Signs of spondylitis or spondylodiscitis may appear later and therefore long follow up is recommended in tuberculous cases presenting with an isolated epidural abscess
One-stage bilateral anterior bikini total hip replacement − experience of two cases
No full textBilateral hip arthrosis is commonly seen and two-staged bilateral Total Hip Arthroplasty (THA) is a preferred choice of treatment due to the fear of complications associated with one-stage bilateral procedures. However, many studies now indicate that the treatment option should be patient specific. We report two cases of one-stage bilateral anterior THA. First, a 54-year-old male operated over a year ago and second a 59-year-old female operated 6 weeks ago. Both presented with a long history of bilateral grade IV hip arthritis causing them severe pain, compromised gait and disturbed sleep. Post-surgery, they were mobilized within few hours after surgery as part of our enhanced recovery programme. There was a drastic increase in their Harris Hip Scores from 34.5 in case 1 and 19.2 in case 2 to 100 for both hips in both patients. They reported excellent recovery, regained normal gait pattern, returned quickly to their routine lifestyle and felt it was an economical option. We conclude that one-stage bilateral bikini anterior THA is a preferred surgical option for patients with bilateral hip arthritis that are medically fit
Risk factors for onset of delirium after neck of femur fracture surgery: a prospective observational study
No full textBackground: Delirium is a common complication after surgery in the elderly that leads to increased length of stay and other adverse outcomes. The aim of this study was to better understand the exact causes of post-operative delirium in patients undergoing surgery for neck of femur (NOF) fractures.
Methods: We performed a prospective cohort study of 381 consecutive patients undergoing surgery for NOF fractures at a single institution. Baseline cognitive status and risk factors were recorded on admission. Post-operative cognitive status was assessed at regular intervals until discharge. Binary logistic regression was performed to identify independent predictors of delirium.
Results: Patients who developed post-operative delirium (n = 70) were significantly older (average age 83 vs. 78, p = 0.019) and more likely to be female (79% vs. 67%, p = 0.062) than non-affected patients. The presence of delirium was associated with increased length of stay (13 vs. 10 days, p = 0.001) and 1-year mortality (25.7% vs. 15% p = 0.03). Independent predictors of delirium included age ≥65 years (Odds Ratio = 5.8), presence of anaemia (OR = 2.9), hypoxia (OR = 2.86), cardiac disease (OR = 2.8), Chronic Obstructive Pulmonary Disease (OR = 2.5), new onset electrolyte imbalance (OR = 2.2) and renal failure (OR = 1.9).
Conclusion: Overall analysis demonstrated an increased incidence of delirium in older females with greater comorbid conditions. It was also found to be associated with increased morbidity and mortality. We recommend clinicians put greater effort into recognising risk factors of delirium and diagnosing it in a timely manner to mitigate its effects
When do patients drive after minimally invasive anterior hip replacements? A single surgeon experience of 212 hip arthroplasties
No full textIntroduction: Patients desire to return to normal activities soon after hip arthroplasty, with driving often being an integral component. We aimed to determine when patients resumed driving following a minimally invasive anterior bikini hip replacement and when they returned to work.
Methodology: All consecutive patients undergoing elective primary bikini hip replacements between January 2017 and April 2018 were included in the study. Patients who did not drive were excluded. A detailed questionnaire was sent to patients 3–6 weeks after surgery to record their driving status. Fifty patients were randomly selected to assess flexion at the hip, knee and ankle joints while seated in the driver's seat of their own vehicle.
Results: Altogether 212 anterior bikini total hip replacements (L = 102, R = 108 and 1 bilateral one stage) were performed in 198 patients (F = 129 and M = 69) with a mean age of 69 years. A total of 76% patients returned to driving within the first 3 weeks after surgery, of which 25 (14%) resumed driving within the first post-operative week, 71 (39%) in the second week and 42 (23%) in the third week. Among them, 98.4% stated they were confident when they first started driving and 90.66% stated they were more comfortable driving after surgery than before. Employed patients returned to work within 1–79 days (mean = 24 days).
Conclusion: Surgeons may allow patients to resume driving within 1 week after anterior hip replacement and return to work within 3 weeks if they are medically fit and deemed safe
Early results of total hip arthroplasty using dual-mobility cup in patients with osteonecrosis of the femoral head
No full textIntroduction: Osteonecrosis of the femoral head (ONFH) remains a therapeutic challenge for patients undergoing total hip arthroplasty (THA). The majority of these patients are young with high functional demand, and show an increased risk of dislocation following surgery than patients with osteoarthritis. The use of double mobility cup (DMC) has been linked with lower rates of complications when compared to conservative cups; however, the literature is scarce over DMC results in patients with ONFH. The aim of the study is to report the early outcomes of patients with ONFH treated with THA-DMC. Materials: A retrospective analysis of patients suffering from ONFH who underwent THA using DMC (THA-DMC) from 2006 to 2015 were evaluated for functional status and risk of post-operative complications. Thirty THA-DMC in 26 patients with a mean follow-up of 51 months were evaluated clinically (modified Hip Harris Score) and radiologically. Results: The mean age of the included patients was 54.9 years. At final follow-up, the mean modified Hip Harris score was 98.7 ± 2.7 and no dislocation episodes or revision surgeries were recorded. The radiological assessment revealed no signs of migration/tilting, radiolucent lines, periprosthetic osteolysis or heterotopic ossification over the DMC component and the femoral stem. The survival rate over 51 months of follow-up was 100%. Discussion: The use of the new generation of dual mobility cup in patients with ONFH showed excellent functional early results with no major complications such as dislocation
