Cannulated screws fixation for nondisplaced femoral neck fractures: early versus late weight-bearing-a prospective analysis.

PURPOSE: Nondisplaced intracapsular fractures (Garden I/II) are predominantly treated with an internal fixation technique. The purpose of the study is to identify the best rehabilitation protocol after internal fixation with 3 parallel cannulated screws. METHODS: All patients operated on from 2016 to 2021 for femoral neck fractures by internal fixation with 3 cannulated screws were enrolled into this prospective study. The population was divided into two groups: Group A (n = 34) who followed a postoperative rehabilitation protocol involving full and immediate loading, and Group B (n = 22) who followed a postoperative rehabilitation protocol involving late full loading (after 30 days). The two groups were compared with each other by mortality rate, postoperative complications and need for re-interventions. Functional outcome and quality of life were assessed at the minimum follow-up of 1 year using the modified Harris Hip Score (HHS) and the Short form health survey (SF-12) questionnaire. RESULTS: Group A showed a lower complication rate (2.9% vs. 18.2%), a lower 1-year mortality rate (5.9% vs. 9.1%), a better perception of mental health status (SF12-MCS 56.2 vs. 51.4, p = 0.03) but a worse perception of one's physical health status (SF12-PCS 48.1 vs. 56.7, p < 0.01). The two groups were also statistically overlapping in terms of the functional outcome achieved after the intervention (HHS was 90.94 in Group A vs. 93.15 in Group B, p = 0.32). CONCLUSION: Postoperative complications, mortality and revision rate were higher in patients who followed a late-loaded rather than early loaded rehabilitation protocol. Functional outcome at 1-year survival is not significantly different. In nondisplaced intracapsular hip fractures treated with cannulated screws, an immediate full load should be preferred. Query.

Gamma nail versus percutaneous compression plate for the treatment of intertrochanteric hip fractures: a multicenter pair-matched study.

PURPOSE: To compare functional outcomes, complication rates, and survival in patients with intertrochanteric fracture treated with percutaneous compression plate (PCCP) or gamma nail (GN). METHODS: A retrospective study of prospectively collected data of patients treated with PCCP or GN for AO/OTA 31.A1 or AO/OTA 31.A2 fractures was conducted. Sixty-eight consecutive patients treated with PCCP between 2018 and 2020 were enrolled and matched with 68 patients with comparable characteristics treated with GN. The activities of daily living (ADL) index and specific scales for walking ability and need for walking aids at 4 months and 1 year after fracture fixation were chosen as primary outcomes. Postoperative complications and one-year survival were recorded and compared between the two groups. RESULTS: Walking ability and ADLs index decreased and the need for walking aids increased in both groups compared to the prefracture state at both follow-up intervals (p < 0.001), regardless of the treatment received. There was no difference between the two implants in the rate of implant-related complications. One-year survival rate was 78.9% (95% CI 67.0-86.9) and 82.4% (95% CI 71.0-89.5) in patients undergoing PCCP or GN, respectively, with no significant difference between the two groups. CONCLUSIONS: Walking ability, ADLs, complication rate, and 1-year survival are not significantly different when patients undergoing PCCP or GN are compared. The choice of implant may not be decisive for the outcome of treatment of intertrochanteric fractures, provided that stable fixation is ensured.

The use of suprapectineal plate in acetabular fractures via ilioinguinal approach with Stoppa window.

Objective: The aim of the study was to investigate the clinical results of open reduction and internal fixation using a suprapectineal buttress plate for specific acetabular fractures. Methods: We conducted a retrospective study involving thirty-three patients with specific acetabular fractures in an academic level 2 trauma center. We performed the ilioinguinal approach with Stoppa window for buttress plating of the quadrilateral surface. Clinical examination, radiographs and computed tomography were done using criteria described by Matta. Functional outcome was evaluated by visual analog scale (VAS), WOMAC, Harris Hip score modified, Hip disability and Osteoarthritis Outcome Score (HOOS) and modified Merle d'Aubignè scoring system. Results: Average follow-up was 40.4 months with a minimum of 24 months. Mean age was 59.09 years. The 82% of patients were treated with a suprapectineal plate using ilioinguinal approach with Stoppa window. The 18% of patients required a Kocher-Langenbeck approach in order to get anatomic reduction of posterior wall or column. The 91% of patients were satisfied of their condition during activity of day living and only a small cohort reported walking aids. The worst clinical results were obtained in patients characterized by highest step displacement. Deep infection of surgical wound was observed in 6% of patients. In 3% of patients, one vascular injury occurred during surgery. Conclusion: Internal fixation using ilioinguinal approach with Stoppa window and a suprapectineal plate to buttress the quadrilateral plate should be considered a viable treatment of some acetabular fractures. Patients can expect a good functional outcome with a low complication rate.

Treatment of periprosthetic supracondylar fractures after CR total knee arthroplasty with retrograde intramedullary nailing in an elderly population: a long term evaluation.

Retrograde intramedullary fixation has been proposed to improve the rate of union providing greater stability in patients with a posterior cruciate ligament retaining femoral TKA component and decreasing soft-tissue trauma. This study assessed the clinical and radiographical outcome of retrograde intramedullary nailing (RIN) for the treatment of periprosthetic supracondylar fractures of the femur in an elderly population. Between January 2014 and December 2018, 16 patients with PSF underwent RIN. The clinical outcome was evaluated using the Knee Society Score (KSS) and the Short-form health survey (SF-12). The radiographic outcome was evaluated directly on the X-rays. Complications were also described. 13 patients (11 females and 2 males) with a mean age of 84 years old (range, 77-89) were evaluated clinically and radiographically, after a mean of 48.3 months (range, 24-73 months). The SF-12 scores were similar to normative values for subjects in the comparable age group. Radiographic union was obtained in all patients after an average of 14,8 weeks (range, 12-40 weeks) postoperatively. RIN is a safe and effective treatment for PSF, above all in the elderly population. The overall clinical and radiographic result was satisfactory.

Assessment of deep vein thrombosis using routine pre- and postoperative duplex Doppler ultrasound in patients with pelvic trauma : a prospective study.

AIMS: The aims of this study were to assess the pre- and postoperative incidence of deep vein thrombosis (DVT) using routine duplex Doppler ultrasound (DUS), to assess the incidence of pulmonary embolism (PE) using CT angiography, and to identify the factors that predict postoperative DVT in patients with a pelvic and/or acetabular fracture. METHODS: All patients treated surgically for a pelvic and/or acetabular fracture between October 2016 and January 2020 were enrolled into this prospective single-centre study. The demographic, medical, and surgical details of the patients were recorded. DVT screening of the lower limbs was routinely performed using DUS before and at six to ten days after surgery. CT angiography was used in patients who were suspected of having PE. Age-adjusted univariate and stepwise multiple logistic regression analysis were used to determine the association between explanatory variables and postoperative DVT. RESULTS: A total of 191 patients were included. A DVT was found preoperatively in 12 patients (6.3%), of which six were proximal. A postoperative DVT was found in 42 patients (22%), of which 27 were proximal. Eight patients (4.2%) had a PE, which was secondary to a DVT in three. None of the 12 patients in whom a vena cava filter was implanted prophylactically had a PE. Multivariate logistic regression analysis indicated that the association with the need for spinal surgery (odds ratio (OR) 19.78 (95% confidence interval (CI) 1.12 to 348.08); p = 0.041), intramedullary nailing of a long bone fracture (OR 4.44 (95% CI 1.05 to 18.86); p = 0.043), an operating time > two hours (OR 3.28 (95% CI 1.09 to 9.88); p = 0.035), and additional trauma surgery (OR 3.1 (95% CI 1.03 to 9.45); p = 0.045) were statistically the most relevant independent predictors of a postoperative DVT. CONCLUSION: The acknowledgement of the risk factors for the development of a DVT and their weight is crucial to set a threshold for the index of suspicion for this diagnosis by medical staff. We suggest the routine use of the DUS screening for DVT in patients with a pelvic and/or acetabular fracture before and six to ten days after surgery.

Chronic Pelvic Diastasis 22 Years After Twin Natural Delivery: A Case Report.

CASE: We present here a case of chronic pelvic separation 22 years after twin natural delivery in a 49-year-old woman surgically treated with anterior and posterior stabilization. The functional and radiological recovery after a 4-year follow-up was extremely good. CONCLUSION: Postpartum pubic symphysis diastasis is a rare but dreaded complication of natural delivery. Nonoperative treatment is still considered the gold standard. However, when pain persists despite nonoperative treatment and when a pelvic radiograph reveals a pubic diastasis greater than 2 cm, surgery is recommended. In the case of low back pain because of sacroiliac joint lesions, posterior fixation is indicated.

Long-Term Survival and Results at a Mean Follow-Up Period of 24 Years of a Tapered Straight, Collarless, Grit-Blasted, Titanium Alloy Stem.

BACKGROUND: There is limited evidence on the survivorship of patients who undergo cementless stem implantation, beyond 20 years of the hip arthroplasty. We report implant survival and results of the CLS Spotorno femoral stem until 30 years from implantation. METHODS: Survival analysis of 147 CLS Spotorno stems in 119 patients for an average period of 24 years (20-30) from the date of implantation was performed. During the course of the follow-up period, 33 patients (39 hips) died. The information on the survival of their hip implant at the time of death was gathered from their relatives and general practitioners. Sixty-six patients (86 hips) undertook the complete survey along with radiographic examination, while 18 subjects (20 hips) were interviewed over the telephone. The factors influencing survival, functional outcomes, and level of satisfaction with surgery were evaluated. RESULTS: The overall estimated survival of the stems was 89.9% after 30 years (95% confidence interval [CI] 83.5-93.9). Survival with femoral revision for aseptic loosening as an end point was 93.1% (95% CI 87.1-96.4). In the worst-case scenario, an overall implant survival of 77.2% (95 CI% 80.3-82.7) was observed after 24 years. Patients who were older than 50 in age at the time of surgery had better survival rates (P = .026). The mean Harris Hip Score at follow-up was 83.1 (range 43-100) and the level of satisfaction was 9/10. The main determinant of postsurgical satisfaction was Harris Hip Score, whereas radiographic alterations explained little with respect to the variation in the outcomes. CONCLUSION: The cementless CLS Spotorno stem displayed satisfactory results 24 years after implantation and high estimated survival until 30 years from surgery. However, patients below the age of 50 at the time of surgery have an increased risk of undergoing revision of their femoral stem.

External Fixation as a Definitive Treatment for Humeral Shaft Fractures: Radiographic and Functional Results With Analysis of Outcome Predictors.

OBJECTIVES: To evaluate the results obtained using unilateral external fixation as a definitive treatment for humeral shaft fractures and to identify possible predictors of radiographic and functional outcomes. DESIGN: Retrospective study. SETTING: One large metropolitan hospital. PATIENTS: A consecutive cohort of 107 patients who underwent external fixation for 109 humeral shaft fractures. MAIN OUTCOME MEASURES: Union rate, time to fracture healing, and functional assessment with disabilities of the arm, shoulder, and hand questionnaire, Constant score, Mayo Elbow Performance Index, and return to prefracture sports activity at a minimum of 2 years after surgery. Comorbidities were evaluated using the Cumulative Illness Rating Scale. Multiple linear regression analysis was used to determine whether any explanatory variables were significantly associated with the outcomes. RESULTS: The union rate in 109 humeral shaft fractures was 97.2% (106/109) at a mean of 99.2 days. Two patients (1.8%) had delayed union, and 1 patient (0.9%) did not achieve union. At the latest follow-up, the mean Constant score, Mayo Elbow Performance Index, and disabilities of the arm, shoulder and hand questionnaire score was 85.6, 97.4, and 7.4 points, respectively. All patients engaged in sports activities before fracture resumed a sport activity. At the multiple linear regression analysis, obesity was directly related to a delayed healing of fracture (P = 0.010) and comorbidity was the most important determinant of the functional outcomes at follow-up (P < 0.001). CONCLUSIONS: These data support the use of unilateral external fixation as an effective therapeutic option in patients with humeral shaft fracture. Comorbidity as assessed by Cumulative Illness Rating Scale score is the most important determinant of functional outcomes. LEVEL OF EVIDENCE: Therapeutic Level IV.

Traumatic hip fracture-dislocation: A middle-term follow up study and a proposal of new classification system of hip joint associated injury.

Traumatic hip fracture dislocation is a rare injury associated with high-energy trauma. Most of these injuries should be surgically treated. Hip dislocation is an orthopaedic emergency and reduction must be performed within 6-8 hours of trauma. We performed a retrospective analysis of 69 patients with "hip joint associated injuries", treated between January 2002 and December 2016. 33 patients were assessed at a mean follow-up of 36.9 months (range 18-132) after surgery. We propose a new classification system in which, different patterns of fracture (head and/or neck and/or acetabular) are described according to different types of hip dislocation. This anatomical-descriptive classification system is based on the concept of hip as a complex anatomical district and contains all possible traumatic injuries associated with hip dislocation. It includes isolated hip dislocation, hip dislocation with femoral head or neck fracture or hip dislocation with acetabular fracture and femoral head fracture. There are 4 groups: Each one of the previous groups is composed by different subgroups. Post-traumatic osteoarthritis is the most common complication of these hip injuries, followed by avascular necrosis of femoral head and heterotopic ossification. The bad prognosis depends on the type of trauma rather than surgical treatment.

Surgical results and factors influencing outcome in patients with posterior wall acetabular fracture.

The purpose of this study was to evaluate the results of open reduction and internal fixation in a large series of posterior wall fractures of the acetabulum and to identify the factors that affect the outcomes in this case series. One hundred twenty-one patients who had undergone open reduction and internal fixation of a fracture of the posterior wall of the acetabulum were assessed at a mean of 53 months (range, 24-163) after surgery. The functional outcome was evaluated with use of the modified Merle d'Aubigne scoring system, the Harris Hip Score (HHS), and the Short Form-36 Health Survey (SF-36) questionnaire. Final follow-up radiographs were graded according to Matta's radiologic criteria. Patient, fracture, and radiographic variables were analyzed to identify possible associations with functional and radiographic outcome. The quality of fracture reduction on postoperative radiographs was anatomical in 115 hips (95.0%), satisfactory in 6 cases (5.0%), and unsatisfactory in none. Final modified d'Aubignè scores were excellent in 45 hips (40.2%), good in 52 (46.4%), fair in 7 (6.3%), and poor in 8 (7.1%). Mean HHS was 91.5±8.9 (48-100). The SF-36 scores were similar with respect to age and sex-matched norms, but physical domains in males remained lower in comparison with the normal population. The early reduction of an associated hip dislocation and quality of surgical reduction were strong positive predictors of functional and radiographic outcomes at follow-up, whereas associated injuries and the existence of pre-operative nerve palsy were negative predictors of patients' functionality. This study of surgically treated fractures of the posterior wall of the acetabulum has shown that functional and radiographic results are satisfactory in most patients, provided that prompt reduction of an associated hip dislocation and anatomical reduction of the fracture are carried out. Associated injuries and nerve lesions affect the final functional outcome.

Effect of surgical correction of adolescent idiopathic scoliosis on the quality of life: a prospective study with a minimum 5-year follow-up.

PURPOSE: To prospectively evaluate the quality of life (QoL), functionality, and body image of subjects who had undergone surgery for adolescent idiopathic scoliosis (AIS) 5-12 years previously, and to identify the outcome predictors. METHODS: The sample consisted of 87 patients for whom follow-up data were available out of a series of 91 patients who had surgery for AIS between 2002 and 2009. We assessed the preoperative, 1-year postoperative, and 5-year or more postoperative SF-36 and SRS-23 questionnaire scores. Longitudinal clinical and radiographic data also were evaluated. Changes in the patient-oriented outcomes were compared with age and sex-adjusted normative values. A multiple regression analysis was used to identify possible outcome predictors. RESULTS: Preoperatively, patients had impaired QoL, functionality, and body image compared to age- and sex-matched healthy controls. Surgery led to significant improvement of the SF-36 and SRS scores at the one-year and final control date, but the final scores on SF-36's physical indexes were lower than control subjects' scores. No clinically relevant differences with the normative values were detected in the final SRS scores. The height of the residual rib hump negatively predicted the total SRS and self-image scores; a more caudal level of fusion correlated with more postoperative pain. CONCLUSIONS: Patients who underwent surgery for AIS a minimum of 5 years earlier had impaired self-reported physical QoL compared to control subjects, but they nevertheless performed better than before their surgery. Greater size of the residual hump and greater distal extension of the fusion area are negatively correlated with final self reported outcome.

Factors Predicting Mobility and the Change in Activities of Daily Living After Hip Fracture: A 1-Year Prospective Cohort Study.

OBJECTIVES: To assess the change in ambulatory ability, need for walking aids, and activities of daily living (ADL) after femoral neck, intertrochanteric, or subtrochanteric fractures and to examine the determinants of these functional outcomes. DESIGN: A prospective observational cohort study. SETTING: A multicenter study involving 1 university hospital and 2 community hospitals. PATIENTS: A consecutive cohort of 552 patients (mean age, 78.3 years; range, 50-105) who underwent surgery for a hip fracture. MAIN OUTCOME MEASURES: Ambulatory ability, need for walking aids, and ADL index, 4 and 12 months after surgery. RESULTS: At both 4 months and 1-year follow-up time points, there was a significant decrease in ambulatory ability and the ADL index score and also an increase in the need for walking aids in comparison with the prefracture status. Ambulatory ability, but not ADL, significantly recovered between the 4-month and 1-year follow-up. One year after fracture, the prefracture functional status was regained by 57% of the patients, but approximately 13% of the formerly ambulating patients were unable to walk. The prefracture status was the most important determinant of ambulatory ability, need for walking aids, and ADL. Comorbidities, a poor cognitive status, and non-weight-bearing status after surgery were also negative predictors. Neither the fracture pattern nor its specific surgical treatment was predictive of any functional outcomes. CONCLUSIONS: Regardless of the type of fracture or surgical treatment used, 57% of the patients do not regain their prefracture ambulatory ability. Recovery of ambulatory ability can occur until 1 year postoperatively. The prefracture status and cognitive level are the most important determinant of all functional outcomes. LEVEL OF EVIDENCE: Prognostic Level I. See Instructions for Authors for a complete description of levels of evidence.

Quality of life and functionality after total hip arthroplasty: a long-term follow-up study.

BACKGROUND: There is a lack of data on the long-term outcome of total hip arthroplasty procedures, as assessed by validated tools. METHODS: We conducted a follow-up study to evaluate the quality of life and functionality of 250 patients an average of 16 years (range: 11-23 years) after total hip arthroplasty using a validated assessment set including the SF-36 questionnaire, Harris Hip Score, WOMAC score, Functional Comorbidity Index, and a study specific questionnaire. Models of multiple stepwise linear and logistic regression analysis were constructed to evaluate the relationships between several explanatory variables and these functional outcomes. RESULTS: The SF-36 physical indexes of these patients compared negatively with the normative values but positively with the results obtained in untreated subjects with severe hip osteoarthritis. Similar results were detected for the Harris Hip Score and WOMAC score. There was a 96% rate of post-surgical satisfaction. Hip functionality and comorbidities were the most important determinants of physical measures on the SF-36. CONCLUSIONS: Patients who had undergone total hip arthroplasty have impaired long-term self-reported physical quality of life and hip functionality but they still perform physically better than untreated patients with advanced hip osteoarthritis. However, the level of post-surgical satisfaction is high.
