A comparison of intramedullary nailing and plate-screw fixation in the treatment for ipsilateral fracture of the hip and femoral shaft

Comparison of reconstruction nails versus dual implants in the treatment of ipsilateral femoral neck and shaft fractures in adults: a meta-analysis and systematic review

OBJECTIVE

There is no consensus on the optimal treatment for ipsilateral femoral neck and shaft fractures. This meta-analysis aims to assess the effectiveness of reconstruction nails and dual implants in treating ipsilateral femoral neck and shaft fractures to provide a basis for decision-making when selecting the optimal approach.

METHODS

Relevant articles were retrieved from Pubmed, Embase, and Cochrane databases using the keywords "neck of femur", "shaft" and "fracture fixation" from inception until November 17, 2022. The screening process of the studies was conducted independently by two assessors, who assessed each study's eligibility and two assessors assessed the quality. Then compared differences in outcome measures using RevMan 5.3 software.

RESULTS

A total of ten retrospective cohort studies were included. There were no significant differences in union time, union rate, union-related complications (malunion, nonunion, delayed union) of femoral neck and shaft fractures, osteonecrosis of the femoral head, and functional outcomes (Friedman-Wyman scoring system) (P > 0.05).

CONCLUSION

Our pooled estimates indicated that reconstruction nails and dual implants for ipsilateral femoral neck and shaft fractures could yield satisfactory surgical results, and that there is no difference between the two treatment methods.

Surgical management of bifocal femoral fractures: a systematic review and pooled analysis of treatment with a single implant versus double implants

INTRODUCTION

Fractures of the proximal femur accompanied by a fracture of the femoral shaft are relatively rare, with a reported prevalence between 1 and 12%. Multiple surgical options are available, consisting of treatment with a single implant or with double implants. Controversy exists about the optimal management. A systematic review and pooled analysis were performed to assess the most reliable treatment for bifocal femoral fractures of the femur.

MATERIALS AND METHODS

A literature search was conducted on July 15, 2022. Selected studies were screened on title and abstract by two researchers independently, and full texts were read by both authors. Emphasis was put on adverse events such as postoperative infection, healing complications, malalignment, and functional outcome using either a single implant or double implants.

RESULTS

For the proximal femoral fractures, no significant difference could be confirmed for avascular necrosis of the femoral neck (5.1% for single implant and 3.8% for double implants), nonunion (6.4% for single implant and 7.8% for double implants), or varus malalignment (6.6% for single implant and 10.9% for double implants). This study also suggests that the number of implants is irrelevant for complications of the femoral shaft regarding the rates of postoperative infection and healing complications. Pooled rates of bone healing complications were 1.6-2.7-fold higher when patients were treated with a single implant, but statistical significance could not be confirmed. For hardware failure, revision surgery, leg length discrepancy, and functional outcome, no difference between the two groups was found either.

CONCLUSIONS

The pooled proportions of all postoperative complications had overlapping confidence intervals; thus, no inference about a statistically significant difference on the number of implants used for treating ipsilateral fractures of the femur can be made. Both treatment groups showed a similar functional outcome at the last moment of follow-up, with more than 75% of the patients reporting a good outcome.

Femoral shaft fractures in eldery patients - An epidemiological risk analysis of incidence, mortality and complications

OBJECTIVES

This work aimed at answering the following research questions: (1) What is the incidence of femoral shaft fractures in the geriatric population in the U.S.? (2) What is the rate of mortality, mechanical complications, nonunion and infection, and what are the associated risk factors?

STUDY DESIGN AND SETTING

In this cross-sectional study, femoral shaft fractures occurred between January 1, 2009, and December 31, 2019, were identified from Medicare records. Rates of mortality, nonunion, infection, and mechanical complications were calculated with the Kaplan-Meier method with Fine and Gray sub-distribution adaptation. Semiparametric Cox regression was applied with twenty-three covariates to determine risk factors.

RESULTS

Between 2009 through 2019 the incidence of femoral shaft fractures decreased by 12.07% to 40.8/100,000 inhabitants (p = 0.549). The 5-year mortality risk was 58.5%. Male sex, age over 75 years, chronic obstructive pulmonary disease, cerebrovascular disease, chronic kidney disease, congestive heart failure, diabetes mellitus, osteoporosis, tobacco dependence, and lower median household income were significant risk factors. The infection rate was 2.22% [95%CI: 1.90-2.58] and the union failure rate 2.52% [95%CI: 2.17-2.92] after 24 months.

CONCLUSION

An early assessment of individual patient risk factors may be beneficial in the care and treatment of patients with these fractures.

Clinicoradiological Outcome of Concomitant Fractures of Proximal Femur and Femoral Shaft Treated With Second-Generation Cephalomedullary Nailing

Background The ideal modality of treatment of concomitant fractures of the hip (intertrochanteric/femoral neck) and the femoral shaft is still evolving. The aim of our retrospective study was to assess the clinicoradiological outcome of such fractures managed by closed second-generation cephalomedullary nailing. Methodology The study was conducted among skeletally mature patients presenting within one week of injury who underwent closed second-generation cephalomedullary nailing (proximal femoral nail). Those presenting beyond one week or those who had pathological fractures, incomplete follow-ups, or other modes of fixation were excluded. Functional results were evaluated according to Friedman and Wyman's clinical assessment system. Time required for fracture healing and the presence of any complications were also noted. Results A total of 10 patients with the ipsilateral hip (five intertrochanteric and five femoral neck) and femoral shaft fractures were included in the study. Associated injuries found included fractures of the ipsilateral tibia/fibula at varying levels in three patients; hand and wrist injuries in two patients; and contralateral femoral shaft fracture, ipsilateral patella, bilateral crush injury of the foot, and head and chest injury with brachial plexus injury in one patient each. Four patients were diagnosed with intra-articular knee injuries (ligamentous and meniscal injuries) postoperatively. At the final follow-up, the functional outcome results were good in four, fair in one, and poor in five patients. All femoral neck fractures united at a mean of 15.2 weeks (range: 12.0-18.0 weeks) and intertrochanteric fractures at a mean of 14.0 weeks (range: 12.0-22.0 weeks). However, there was residual varus malunion in two intertrochanteric fractures. Eight femoral shaft fractures were infra-isthmic; of these, four resulted in nonunion (two of hypertrophic and two of atrophic type) and two were found to be in the delayed union, which eventually united by 24 weeks. Conclusions Second-generation cephalomedullary nail is an acceptable, cost-effective, and minimally invasive alternative for the management of concomitant ipsilateral fractures of the hip and supra-isthmic or isthmic femoral shaft fractures. For infra-isthmic fractures, retrograde femoral nail or distal femoral plate along with a separate implant for addressing the hip fracture (either cannulated cancellous screw or dynamic hip screw, preferably in a rendezvous/overlapping manner) are better options.

Salvaging Chronic Nonunion of Femoral Neck and Infected Nonunion of Ipsilateral Femoral Shaft Fracture Using Intramedullary Antibiotic Cement Spacer and External Fixator Alone

Concomitant ipsilateral fractures of femoral neck and shaft are rare injuries and pose challenging management. Infected non-unions of such fractures can further complicate the management options and have not been discussed in the literature. We present a case of an eight-month-old atrophic non-union of ipsilateral femoral shaft and femoral neck with evidence of intramedullary infection that was managed using a cost-effective, low strain rail fixator assembly and an intramedullary antibiotic cement spacer. Both fracture non-unions were salvaged without the need for any additional procedure. The patient returned to his regular activities within a year follow-up period. There was no clinical evidence of infection during the last follow-up at 16 months, and inflammatory markers were within normal limits. The current case study suggests that while aggressive debridement and intramedullary antibiotic cement spacer can control the intramedullary infection, and simultaneous union of even atrophic nonunion of femoral shaft and femoral neck, both, can be obtained using a tensioned Schanz pin-based external fixator without the need for any secondary procedure. Such a fixator and cement spacer assembly can thus address the dual purpose of fracture stabilization during infection control as well as the union of the non-union sites.

Application of fracture-sustaining reduction frame in closed reduction of femoral shaft fracture

Objectives

This study aims to explore the clinical efficacy of applying a new reduction brace in the closed reduction of femoral shaft fracture.

Methods

A total of 18 patients with femoral shaft fracture, who were admitted to the Bone Trauma Surgery, Second Hospital of Shanxi Medical University, from September 2015 to January 2017, were chosen. A novel reduction brace combined with closed reduction intramedullary nail insertion on the traction table adopted for the orthopedic surgery was taken for the fixation. Then, surgical time, bleeding amount, and postoperational fracture healing time were recorded.

Results

All 18 patients with femoral shaft fracture successfully received closed reduction femoral nail with the application of the novel reduction brace. The follow-up period was 3–18 months, with an average of 12 months, and the femoral shaft fracture was well healed with good recovery of function.

Conclusions

The design of the closed reduction brace of the femoral shaft fracture was reasonable, simple, and convenient to use and has a short learning curve. Furthermore, it led to little trauma to these patients and fully played the advantages of minimally invasive therapy for femoral fractures.

Nonunion and Reoperation After Internal Fixation of Proximal Femur Fractures: A Systematic Review

Nonunion after fixation of a proximal femur fracture is associated with increased disability, pain, and cost to both patient and health care system. Understanding the effect of fixation method and fracture pattern on healing is important to optimize healing. The authors evaluated surgical healing, nonunion rate, and reoperation rate after internal fixation of proximal femur fracture, especially since the year 2000. They performed a systematic review of all published records from PubMed, Embase, and the Cochrane Review system. The burden of proximal femoral fracture extends beyond acute disability, as it carries a high risk of long-term morbidity and mortality. Choice of fixation method for high-risk fractures is critical to reduce nonunion and reoperation rates. [Orthopedics. 2019; 42(2):e162-e171.].

Improve the Efficiency of Surgery for Femoral Shaft Fractures with A Novel Instrument: A Randomized Controlled Trial

Objective

To improve the efficacy of closed reduction and wire guiding during intramedullary nail internal fixation in femoral shaft fractures.

Methods

A novel instrument was designed and manufactured. Sixty-eight patients were enrolled from February 2011 to December 2013. The instrument designed was used during the operation in the experimental group, but not in the control group.

Results

All patients exhibited fracture union, excluding 1 patient in the experimental group and 2 in the control group who had non-union; all of whom achieved fracture union with reoperation. There were no statistically significant differences in operative blood loss or duration of hospital stay between the groups (P > 0.05). The operative time, frequency of wire drilling, and number of open reduction cases, were significantly smaller in the experimental group than in the control group (P < 0.05).

Conclusion

Femoral shaft fractures are difficult to reduce using general methods; the novel instrument showed high clinical value and proved effective and safe in assisting with closed reduction and intramedullary nail fixation for femoral shaft fractures.

Algorithm for the management of femoral shaft fractures in children

PURPOSE

Pediatric closed femoral shaft fractures are commonly related to a good prognosis. There is no consensus on treatment. We aimed to evaluate the treatment, features, radiological findings and management strategies, creating an algorithm of treatment.

MATERIALS AND METHODS

Fifty-two simple femoral shaft fractures in children were retrospectively evaluated for age and gender distribution, side of the fracture, etiology of injuries, limb length discrepancy, range of knee and hip motion and parents satisfaction with a mean clinical and radiographic follow-up of 3 years and 6 months. Twenty-eight patients were treated with reduction and early hip spica cast while 24 patients were treated with external fixation (EF).

RESULTS

Nearly 58 % of the cases were caused by traffic accidents and were predominantly male (61.5 %). Most of the fractures were of the middle femoral shaft (57.6 %). Muscle strength was normal (MRC scale) in all patients with no pain (NIPS and PRS scale). Knee and Hip range of motion were similar in both types of treatment. Patients treated with EF had shorter limb length discrepancy compared with SC. There were no reports of re-fracture. We found a higher familiar satisfaction in patients treated with EF.

CONCLUSIONS

An algorithm for the management of femoral shaft fractures in the pediatric population is proposed. Results on the study population gave raise to a satisfactory clinical and radiological results.
