Surgical Selection of Unstable Intertrochanteric Fractures: PFNA Combined with or without Cerclage Cable

Prospective Research Comparing Different Trochanteric Fracture Fixation Techniques

Aim Evaluation and comparison of various methods of trochanteric fracture fixation. Methods This study was conducted prospectively at the Orthopaedics Department of Dr. D Y Patil Medical College and Research Centre. The study spanned 18 months and involved 100 patients treated in the outpatient and the emergency department. Patients who fulfilled that specific criteria were selected for this study and the appropriate surgical intervention for each group was determined through radiological examination. Results Of the 100 patients, 55 (55%) were male and 45 (45%) females. Patients in our collection ranged from 20 to 90 years old. Proximal Femoral Nail (PFN), Dynamic Hip Screw (DHS ), and Proximal Femoral Locking Compression Plate (PFLCP ) groups averaged 56, 58, and 64 years old, respectively. The most common cause of intertrochanteric fracture was domestic falls (60%), followed by road traffic accidents (35%). The Arbeitsgemeinschaft für Osteosynthesefragen (AO) classification rated 40 individuals (40%) as stable and 60 as unstable. Most patients in our study had unstable A3 fractures. PFN patients had 16 A3 fractures. In DHS, 32 patients suffered A3 fractures. Twelve PFLCP patients suffered A3 fractures. The smallest group had A1 fractures. Six PFN patients suffered A1 fractures. Two DHS patients had A1 fractures. Two PFLCP patients suffered A1 fractures. PFN group mean scores improved significantly after one and three months in this study. At six months, the PFN group had a significant mean score improvement. Conclusion PFN results ranged from satisfactory to excellent, offering numerous advantages over other methods such as DHS and PFLCP. The benefits of PFN include a shorter lever arm, fracture site compression, and enhanced rotational stability, which contribute to a lower chance of mechanical failure. Additionally, patients treated with PFN typically experience shorter hospital stays, earlier mobilization, less blood loss, shorter surgery times, faster rehabilitation, and quicker bone healing, making PFN a highly effective treatment option for certain fractures.

Is Sliding Compression Necessary for Intramedullary Nailing Fixation of AO/OTA Type A3.3 Intertrochanteric Fracture?

OBJECTIVES

The intramedullary nail is considered the gold standard for treating AO/OTA type A3.3 intertrochanteric fractures. However, it still faces a significant rate of failure, mainly due to the critical factor of comminuted lateral wall defects leading to inadequate proximal sliding compression. The primary objective of this study is to investigate the requirement of sliding compression in the treatment of unstable AO/OTA type A3.3 intertrochanteric fractures. To achieve this, we conduct a comparative analysis between two approaches: InterTAN alone and proximal femoral anti-rotation blade nailing (PFNA) combined with lateral wall reconstruction for treating AO/OTA type A3.3 intertrochanteric fractures with lateral wall damage.

METHODS

A retrospective analysis was conducted on the clinical data of patients who underwent intramedullary nailing fixation for AO/OTA type A3.3 intertrochanteric fractures at our hospital from January 2012 to January 2022. Patient characteristics as well as treatment details, including operative time, intraoperative blood loss, weight-bearing time, fracture healing time, tip apex distance (TAD) loss, Harris hip scores (HHS), Parker-Palmer mobility score (PPMS), and postoperative complications, were collected and analyzed. Continuous variables were analyzed using independent sample t-tests, while categorical variables were examined using the chi-square test. For group comparisons, variance analysis was applied, and pairwise comparisons were conducted using the LSD-t test.

RESULTS

These patients were divided into PFNA combined with lateral wall reconstruction group (sliding compression group) and InterTAN fixation group (static fixation group) based on surgical methods. The operation time, intraoperative bleeding loss, HHS at 12 months and PPMS at 12 months in the sliding compression group were significantly higher than those in the static fixation group, and time to weight-bearing and fracture healing time were significantly lower than those in the static fixation group (p < 0.05). There were no significant differences between two groups in terms of the TAD at 2 days, 2, and 12 months postoperatively, the incidence of complications (p > 0.05). At 6 months postoperatively, femoral neck length was shortened compared to 2 days postoperatively in both groups, and the sliding compression group had a significantly greater degree of femoral neck shortening than the static fixation group (p < 0.05).

CONCLUSION

The use of PFNA with lateral wall reconstruction for A3.3 intertrochanteric fractures demonstrated superior mobility, efficiency, and reduced internal fixation failure rates compared to InterTAN. These findings suggest that sliding compression may be required for intramedullary nailing treatment.

Barriers and facilitators of weight bearing after hip fracture surgery among older adults. A scoping review

PURPOSE

This scoping review aimed to synthesise the available evidence on barriers and facilitators of weight bearing after hip fracture surgery in older adults.

METHODS

Published (Cochrane Central, MEDLINE, EMBASE, CINAHL, and PEDro) and unpublished (Global Health, EThOS, WorldCat dissertation and thesis, ClinicalTrials.gov , OpenAIRE, DART-Europe) evidence was electronically searched from database inception to 29 March 2022. Barriers and facilitators of weight bearing were extracted and synthesised into patient, process (non-surgical), process (surgical), and structure-related barriers/facilitators using a narrative review approach.

RESULTS

In total, 5594 were identified from the primary search strategy, 1314 duplicates were removed, 3769 were excluded on title and abstract screening, and 442 were excluded on full-text screening. In total, 69 studies (all from published literature sources) detailing 47 barriers and/or facilitators of weight bearing were included. Of barriers/facilitators identified, 27 were patient-, 8 non-surgical process-, 8 surgical process-, and 4 structure-related. Patient facilitators included anticoagulant, home discharge, and aid at discharge. Barriers included preoperative dementia and delirium, postoperative delirium, pressure sores, indoor falls, ventilator dependence, haematocrit < 36%, systemic sepsis, and acute renal failure. Non-surgical process facilitators included early surgery, early mobilisation, complete medical co-management, in-hospital rehabilitation, and patient-recorded nurses' notes. Barriers included increased operative time and standardised hip fracture care. Surgical process facilitators favoured intramedullary fixations and arthroplasty over extramedullary fixation. Structure facilitators favoured more recent years and different healthcare systems. Barriers included pre-holiday surgery and admissions in the first quarter of the year.

CONCLUSION

Most patient/surgery-related barriers/facilitators may inform future risk stratification. Future research should examine additional process/structure barriers and facilitators amenable to intervention. Furthermore, patient barriers/facilitators need to be investigated by replicating the studies identified and augmenting them with more specific details on weight bearing outcomes.

Residual lateral wall width predicts a high risk of mechanical complications in cephalomedullary nail fixation of intertrochanteric fractures: a retrospective cohort study with propensity score matching

PURPOSE

The purpose of this study is to determine whether the integrity of the entry portal of head-neck implant is related to postoperative mechanical complications.

METHODS

We retrospectively reviewed consecutive patients with pertrochanteric fractures in our hospital treated from January 1, 2018, to September 1, 2021. Based on the integrity of the entry portal for head-neck implants on the femoral lateral wall, patients were divided into two groups, including the ruptured entry portal (REP) group and the intact entry portal (IEP) group. After 4:1 propensity score-matched analyses were used to balance the baseline of the two groups, a total of 55 patients were extracted from the original participants, including 11 patients in the REP group and 44 matched patients in the IEP group. The anterior to posterior cortex width on the mid-level of the lesser trochanter was measured and defined as the residual lateral wall width (RLWW).

RESULTS

Compared with the IEP group, the REP group was correlated with postoperative mechanical complications (OR = 12.00, 95% CI 1.837-78.369, P = 0.002) and hip-thigh pain (OR = 26.67, 95% CI 4.98-142.86). RLWW ≤ 18.55 mm indicated a high likelihood (tau-y = 0.583, P = 0.000) of becoming the REP type postoperatively and being more likely to suffer from mechanical complications (OR = 30.67, 95% CI 3.91-240.70, P = 0.000) and hip-thigh pain (OR = 14.64, 95% CI 2.36-90.85, P = 0.001).

CONCLUSION

Rupture of entry portal is a high-risk factor for mechanical complications in intertrochanteric fractures. RLWW ≤ 18.55 mm is a reliable predictor of the postoperative REP type.

Comparing the supine and lateral positions for proximal femoral nail use in the treatment of intertrochanteric femoral fractures

Background/Aim: The management of unstable intertrochanteric fractures (ITF), which are becoming more common, is still a significant issue for public healthcare systems. As a result, successful fracture therapy is becoming a more crucial aspect of orthopedic practice. To treat older patients who have an ITF, this study compared the therapeutic outcomes and side effects of proximal femoral nail anti-rotation (PFNA) conducted in lateral decubitus and supine postures. Methods: One-hundred twenty patients between the ages of 65 and 90 who underwent PFNA surgery as a result of an unstable femoral ITF brought on by low-energy trauma were included in the study, which was conducted as a retrospective cohort study. Two groups of patients were established: (1) Group L, consisting of patients who underwent surgery in the lateral decubitus position and (2) Group S, consisting of patients who underwent surgery in the supine position. Several patient characteristics were compared: (1) demographic information, (2) length of hospital stay, (3) length of surgery, (4) intra-operative blood loss, (5) incision length, (6) number of intra-operative fluoroscopies, (7) duration of activity outside of bed, (8) duration of clinical recovery of fracture, (9) surgical complications, (10) patient outcomes, and (11) Harris hip scores (HHS). Results: Group L (60 patients) consisted of patients who underwent surgery in the lateral decubitus position, while Group S (60 patients) underwent surgery in the supine position (60 patients). The average hospital stay for patients receiving PFNA was 8.2 days for those in the supine position compared to 8.0 days for those in the lateral decubitus position. The difference between the operative times was significant (P<0.001) with 48.6 and 59.7 min in Groups L and S, respectively. Intra-operative blood losses in Groups L and S were 129.2 and 151.5 mL, respectively. Compared to Group S, Group L's mean incision length was much lower at 6 cm (as compared to 8 cm in Group S). The difference between the mean intra-operative radiation exposure times for Groups L and S was considerable at 9.38 versus 12.5 min. The mean times for fracture union and the HHS were not statistically different between the two groups after 12 weeks of treatment. Conclusion: ITFs in elderly patients can be successfully treated with PFNA in either the lateral decubitus or supine position. Surgical duration, blood loss, intra-operative X-ray exposure, and incision lengths were all reduced with PFNA performed in the lateral decubitus position. As a result, treatment of ITFs in older individuals may involve PFNA fixation in the lateral decubitus position. Particularly for people with a muscular gluteal region or obese patients, the lateral decubitus position is advised.

RECONSTRUCTION OF THE TROCHANTERIC ZONE IN PRIMARY ARTHROPLASTY OF UNSTABLE PERTROCHANTERIC FRACTURES

OBJECTIVE

The aim: To justify the concept and features of acetabular reconstruction during primary endoprosthesis for transcatheter fractures from the standpoint of radiological data, biomechanical calculations and intraoperative observations.

PATIENTS AND METHODS

Materials and methods: A retrospective analysis of the use of primary cement arthroplasty for osteoporotic fractures of the trochanteric zone in 52 elderly and senile patients was conducted. Before implantation of the femoral component, fragments of the proximal metaphysis were fixed with cerclage tightening loops which depended on the type of fracture. For fractures 31-A2.1, 31-A2.2, 31-A2.3, reconstruction of the destroyed trochanteric zone and the walls of the bone marrow canal opening was performed using our own methodology. Finite-element modeling with the SolidWorks program was used to investigate the influence of the reconstruction of the trochanteric zone on the distribution of strain on the bone tissue around the implant under osteopenic conditions and load during single-support standing.

RESULTS

Results: Clinical and X-ray results were studied in 39 (74.36%) operated patients within 3 to 33 months. There were no complications associated with recon-struction of the proximal part of the femur and implantation of endoprostheses. Restoration of movements in the hip joint and full loading of the operated limb was allowed the day after surgery, depending on the patients` physical condition. The results of finite-element modeling indicate a significant reduction of the strain on the proximal metaphysis in the zone of predominant destruction of the medial and posterior walls of the bone marrow canal of the trochanteric zone reconstruction and ensuring the stability of the femoral component.

CONCLUSION

Conclusions: Clinical results and biomechanical calculations confirm the possibility and feasibility of using primary arthroplasty in unstable osteoporotic fractures of the trochanteric zone with the aim of early restoration of the support function of the damaged limb in individuals with limited physical capabili¬ties. Reconstruction of the intertrochanteric area with a ring-shaped autograft contributes to the achievement of primary stability of the femoral component, restoration of the total femoral offset and stabilizing function of muscles around the joints.

Prospective Comparative Study Between Proximal Femoral Nail vs. Screw Augmented Proximal Femoral Nail in Unstable Intertrochanteric Fractures of Femur

Introduction The proximal femoral nail (PFN) is a widely accepted fixation method for the management of unstable intertrochanteric fractures. Reconstructing the lateral trochanteric wall and ensuring the stability of the trochanteric fragments are considered to be essential for enhancing the prognosis of unstable intertrochanteric fractures. The aim of this study is to evaluate and compare the results of the management of unstable intertrochanteric fracture of the femur using PFN and the screw-augmented PFN (aPFN). Methods This prospective comparative study was undertaken from January 2020 to July 2021 and included 60 patients presenting with unstable intertrochanteric fractures (AO/OTA type 31-A2.2 and 31-A2.3) at a tertiary care teaching institute in northern India. The enrolled patients were randomly divided into two groups (group 1 and group 2) and were managed with screw-augmented PFN and PFN, respectively. Functional outcome was evaluated using the Salvati and Wilson score at the 12-month follow-up. SPSS version 24.0 (IBM Corp., Armonk, NY, USA) was used for statistical analysis. A p-value less than 0.05 was regarded as significant. Results The average time to union of the fractures in group 1 was 12.66 ± 1.68 weeks, while it was 13.47 ± 1.47 weeks in group 2 (p = 0.055). At the 12-month follow-up, the average functional outcome, as evaluated by Salvati and Wilson score, was 34 ± 2.40 in group 1, whereas it was 31.58 ± 4.4 in group 2; and the difference was observed to be statistically significant (p = 0.011). Group 1 had 28 patients (93.33%) with excellent to good results, while group 2 had 25 patients (83.33%) with excellent to good results. One patient in group 1 and five patients in group 2 had poor outcomes at the 12-month follow-up. Conclusion Screw-augmented PFN has better functional outcomes as compared to PFN alone for the management of unstable intertrochanteric fractures. Hence, in our opinion, screw augmentation of PFN may be the better fixation technique for most unstable intertrochanteric femur fractures.

The effect of cerclage wiring with intramedullary nail surgery in proximal femoral fracture: a systematic review and meta-analysis

PURPOSE

The aim of this study was to evaluate the utility of cerclage wiring with intramedullary nail surgery in the treatment of proximal femoral fractures.

METHODS

MEDLINE, Embase, and Cochrane Library were systematically searched for studies that evaluated the impact of cerclage wiring on proximal femoral fractures published up to September 20, 2021. Pooled analysis identified differences in the (1) fracture healing profile, (2) perioperative variables, (3) complications, and (4) clinical outcome score between cerclage wiring and non-cerclage wiring.

RESULTS

Fourteen studies involving 1,718 patients with proximal femoral fractures who underwent cephalomedullary nailing surgeries were included. The pooled analysis revealed a longer fracture union time in the non-cerclage wiring group than in the cerclage wiring group (mean difference [MD] = - 1.03 months; 95% confidence interval [CI]: - 1.47 to - 0.59; P < 0.001), and there was no difference in the nonunion rate. The operation time was longer in the cerclage wiring group (MD = 14.32 min; 95% CI: 6.42-22.22; P < 0.001), but there were no differences in blood loss and the rate of poor quality of reduction. Superficial and deep infection rates showed no difference between the groups, and the readmission rate also showed no difference. The cerclage wiring group had a higher Harris hip score than the non-cerclage wiring group (MD = 2.13; 95% CI: 0.77-3.49; P = 0.002).

CONCLUSIONS

Intramedullary nailing with cerclage wiring is considered a useful treatment method for proximal femoral fractures. It enables anatomic reduction and stable fixation, thereby reducing union time and facilitating rapid functional recovery.
