Lower body bone fractures have high mortality rates and poor prognosis in the patients with hemodialysis.

INTRODUCTION: The objective of the current study was to investigate the association between lower body bone fractures occurring during maintenance hemodialysis and prognosis. METHODS: This study included 151 hemodialysis patients at the dialysis center of our hospital as of December 2017, and data were systematically gathered from medical records over a period of 5 years, concluding in December 2022. RESULTS: Fourteen patients, 3.0 per 100 person-years, in 151 hemodialysis patients suffered from lower body bone fractures. The ratio of males was significantly lower, and age was significantly higher in the lower body bone fracture group than in the no lower body bone fracture group. Duration of hemodialysis prior to entry into this study was significantly shorter in the lower body bone fracture group than in the no lower body bone fracture group. Serum albumin was significantly lower and alkaline phosphatase was significantly higher in the lower body bone fracture group than in the no lower body bone fracture group. Mortality rate was significantly higher in the lower body bone fracture group (85.7%) compared to no lower body bone fracture group (28.5%) (p = 0.01). Kaplan-Meier survival curves for mortality showed that lower body bone fracture group had poor prognosis compared to no lower body bone fracture group. Multivariable-adjusted odds ratio for mortality were significantly higher for cases with lower body bone fractures. CONCLUSION: Lower body bone fractures have high mortality rates and poor prognosis in the patients with hemodialysis.

Pipkin type III femoral head fracture: which treatment strategy can be recommended?

BACKGROUND: Pipkin type III femoral head fractures are relatively rare injuries. Few studies have explored and described the treatment and outcomes of Pipkin type III femoral head fractures. The purpose of this study was to evaluate the efficacy of open reduction and internal fixation (ORIF) in treating Pipkin type III femoral head fractures. METHODS: We retrospectively reviewed 12 patients with Pipkin type III femoral head fractures who underwent ORIF from July 2010 and January 2018. The complications and reoperations were recorded. The visual analog scale (VAS) pain score, Harris hip score (HHS), Thompson-Epstein criteria, and SF-12 score [including the physical component summary (PCS) and the mental component summary (MCS)] were used for functional assessment. RESULTS: Among the 12 patients, ten were males and two were females, with a mean age of 34.2 ± 11.9 years. The median follow-up time was 6 years (range 4-8 years). Five patients (42%) developed osteonecrosis of the femoral head, and one patient (8%) developed nonunion. These six patients (50%) underwent total hip arthroplasty (THA). One patient (8%) developed heterotopic ossification and underwent ectopic bone excision; this patient also presented with post-traumatic arthritis. The mean final VAS pain score and HHS were 4.1 ± 3.1 points and 62.8 ± 24.4 points, respectively. According to the Thompson-Epstein criteria, there was one patient (8%) with excellent, four patients (33%) with good, one patient (8%) with fair, and six patients (50%) with poor outcomes. The PCS score and MCS score were 41.7 ± 34.7 points and 63.2 ± 14.5 points, respectively. CONCLUSION: Limited by the high incidence of osteonecrosis of the femoral head, it is difficult to achieve satisfactory functional outcomes when treating Pipkin type III femoral head fractures using ORIF, and a primary THA may be considered. However, for younger patients, considering the survivorship of prosthesis, ORIF may be recommended with the proviso that the patient is fully informed of the high complication rate associated with this procedure. LEVEL OF EVIDENCE: IV.

Clinical effects of direct anterior internal fixation with Herbert screws on hip joint function and quality of life in patients with Pipkin II femoral head fractures.

OBJECTIVE: The study aimed to explore the therapeutic effects of direct anterior internal fixation with Herbert screws on hip joint function and quality of life in patients with Pipkin type II femoral head fractures (FHF). METHODS: From Dec 2017 to Jul 2020, 68 patients with Pipkin type II FHF were received in our hospital and divided into two groups. The direct anterior internal fixation (DAIF) group including 34 cases were treated by direct anterior internal fixation with Herbert screws. The control group of 34 patients received modified internal fixation with Herbert screws via posterior superior iliac spine and ectogluteus. The duration time and blood loss in operation as well as the postoperative drainage volume, hospital stays and complications were observed. The comparison of pain degree, hip functions, and life quality between two groups was performed. RESULTS: All the patients were followed up, and the operative time, intraoperative blood loss, postoperative drainage and hospital stay of the DAIF group were all significantly lower than those in the control group, with (p < 0.05, respectively). The pain degree of the DAIF group was significantly lower than that of the control group 7, 15 and 30 days after the operation (p < 0.05, respectively). At 3, 6 and 9 months after the operation, the hip function recovery of the DAIF group was significantly better than control group (p < 0.05). There were no significant differences between the two groups in preoperative physiological function, physiological function, emotional role, physical pain, general health, vitality, social function and mental health (p > 0.05). Six months after the operation, the physiological function, physiological function, emotional role, physical pain, general health, vitality, social function and mental health of the DAIF group were significantly higher than those of the control group (p < 0.05). No postoperative complications occurred in both groups. CONCLUSION: The treatment of directly anterior internal fixation with Herbert screws is effective for Pipkin type II FHF, like improving the function of hip joint and quality of life in patients. The method is reliable and worth clinical use.

Efficacy of direct anterior approach combined with direct posterior approach in Pipkin IV femoral head fractures.

OBJECTIVE: The study aimed to explore the efficacy of direct anterior approach combined with direct posterior approach in Pipkin IV femoral head fractures. METHODS: The study enrolled 64 patients with Pipkin IV femoral head fractures who were treated at our hospital between March 2019 and April 2020. They were assigned to the control group and the study group using the random number table method with 32 patients in each group and received treatment by the direct anterior approach and treatment by the direct anterior approach combined with the direct posterior approach. The operative time, intraoperative estimated blood loss, postoperative drainage time, drainage volume, time to partial and full weight-bearing, total length of hospital stay and the levels of hemoglobin (Hb) and hematocrit (Hct) in the two groups were compared, and severity of pain and hip function at different time points postoperatively were observed, and the occurrences of complications were compared. RESULTS: There was no statistical difference in the operative time and intraoperative estimated blood loss between the two groups (P > 0.05). Compared with the control group, the study group had shorter postoperative drainage time, lower drainage volume, shorter time to partial and full weight-bearing, and shorter total length of hospital stay, and the difference was statistically different (P < 0.05). There was no significant difference in Hb and Hct levels between the two groups before surgery (P > 0.05). The levels of Hb and Hct in both groups at postoperative day (POD) 1 were lower than those before surgery, and the levels of Hb and Hct in the study group were significantly higher than those in the control group (P < 0.05). Compared with the control group, the study group had significantly less severe pain at POD 1 and 7 and 1, 3 and 6 months postoperatively (P < 0.05). Compared with the control group, the study group had significantly better hip function at 3, 6 and 12 months postoperatively (P < 0.05). All patients were followed up for 12 months, and 1 case of ectopic ossification appeared in both groups 3 months postoperatively, both Brooker grade I. No special treatment was provided as it did not interfere with the mobility of the hip and caused no apparent discomfort in the patients. In the current study, no incision infection, ischemic necrosis of the femoral head, breakage of the internal fixation device, fracture nonunion and loss of fracture reduction and other complications were reported in any patients. CONCLUSION: Direct anterior approach combined with direct posterior approach in Pipkin IV femoral head fractures does not increase operative time and intraoperative estimated blood loss but can lessen severity of pain and promote functional recovery of the hip, leading to a favorable prognosis while not increasing the incidence of complications.

Gibson approach and surgical hip dislocation according to Ganz in the treatment of femoral head fractures.

BACKGROUND: The purpose of the study is to evaluate clinical and radiological outcomes in those patients with femoral head fracture, treated with open reduction and internal fixation through Gibson approach and Ganz flip trochanter osteotomy. The treatment of Pipkin fractures is very challenging, especially for small trauma centers, because of the unusual fracture patterns and high-level surgical skills required. CASE PRESENTATION: Between 2017 and 2020, nine cases of Pipkin fractures came to the Emergency Department at the Trauma Center of our Hospital in Rome. Inclusion criteria were the diagnosis of femoral head fracture, the open reduction and internal fixation as surgical choice and at least 24 months follow-up. Patients older than 65 years and those treated through total hip replacement or combined hip procedure (CHP) were excluded. Thus, five patients were included in our case series. The clinical outcome was evaluated according to Western Ontario and McMaster Universities Arthritis Index, Vail Hip score, modified Harris Hip score and Merle D'Aubignè Postel score. Radiographic assessment was scored according to Epstein-Thompson classification and heterotopic ossification was assessed through Brooker classification. The mean follow-up was 24 months (range 12-24). Average modified Harris Hip score was 92.1 points (range 75.9-100), and the average Vail score was 81.8 (range 55-95). WOMAC score was assessed in three different subscales, pain (A), stiffness (B) and physical condition (C), with the following results: 1.4 A (range 0-7), 1.2 B (range 0-6) and 6.4 C (range 0-22). Merle d'Aubignè Postel score resulted excellent for four patients and good for one patient. According to Epstein-Thompson score of the radiological outcome, four patients showed a good result and one a fair result. No mechanical or infective complications occurred in the five patients. CONCLUSIONS: Gibson's approach and surgical hip dislocation through Ganz trochanteric flip osteotomy allow a good exposure of the femoral head and acetabulum, giving us the possibility to perform an anatomical reduction of the fracture. In our case series, satisfactory clinical and radiological short-term results were obtained without significant complications.

Functional Outcome of Pipkin Type III Fracture Managed by Osteosynthesis through Trochanteric Flip Osteotomy in a Young Patient after 5 Years Follow-Up - A Case Report and Literature Review.

INTRODUCTION: Femoral head fractures are uncommon. A femoral head fracture associated with an ipsilateral neck of femur fracture is classified as a Pipkin's Type III fracture and is exceedingly rare. It is a high-energy injury associated with an extremely poor prognosis. This has led some authors to advocate primary arthroplasty for these injuries. The aim of reporting this case is that in young patients even with severely displaced Pipkin's Type III injuries, it is reasonable to opt for internal fixation of these fractures. It is possible to obtain good function for a significant amount of time as evidenced by the 5-year follow-up in this case. CASE REPORT: A 25-year-old male presented 4 days after a motorbike accident. He was diagnosed as a femoral head fracture with neck fracture of the left side. This fracture is classified as type III Pipkin fracture or OTA type 31C.3. This case was managed with open reduction and internal fixation utilizing the trochanteric flip osteotomy and multiple screws. It is worth to report the first case of Pipkin type three fracture having satisfactory functional outcome after 5 years of follow-up. CONCLUSION: It is worth preserving the femoral head in young patients. Good pre-operative planning, meticulous reduction, tissue handling, and fixation could get satisfactory results. The outcome also depends on post-operative rehabilitation and compliance of patient.

3D printing-based Ganz approach for treatment of femoral head fractures: a prospective analysis.

BACKGROUND: Femoral head fractures are uncommon injuries. Open reduction and internal fixation (ORIF) of femoral head fracture is the preferred treatment for most patients. There are several surgical approaches and treatments for this difficult fracture. However, the optimal surgical approach for the treatment of femoral head fracture remains controversial. Meanwhile, the operation is difficult and the complications are numerous. We prospectively reviewed patients with femoral head fractures managed surgically through the 3D printing-based Ganz approach to define a better approach with the least morbidity. PATIENTS AND METHODS: Between 2012 and 2017, a total of 17 patients were included in this study. An exact 1:1 3D printing model of the injured hip side was fabricated for each patient and simulated surgery was finished preoperative. The surgical approach was performed as described by Ganz. Functional assessment was performed using the modified Merle d'Aubigne scores. The reduction of the fracture was evaluated according to Matta's criteria. The incidence of complications, such as heterotopic ossification (HO) and avascular necrosis (AVN), and the need for additional surgery were also documented. RESULTS: Twelve of 17 patients (four females and eight males) were available for 2 years follow-up. The mean follow-up was 35 months (25-48 months). Average age for the 12 patients was 39.9 ± 12.2 years. According to the Pipkin classification, four patients were type I fracture, three patients were type II fracture, and five patients were type IV fracture. The mean operative time was 124.2 ± 22.1 min, and the estimated blood loss was 437.5 ± 113.1 ml. According to Merle d' Aubigne scores, excellent results were achieved in six of the 12 patients; four good and two poor results occurred in the rest of the patients. On the radiograph evaluation, fracture reduction was defined as anatomical in eight patients, and imperfect in four. Most patients had good outcomes and satisfactory hip function at last follow-up. Almost all great trochanteric osteectomy healed uneventfully. One patient developed symptomatic AVN of the femoral head and underwent THA at 3 years. After THA, she regained a good hip function with the ability to return to work and almost no reduction in sports activities. Heterotopic ossification was found in four cases (type I-1, type II-2, and type III-1). CONCLUSIONS: The 3D printing-based Ganz approach provides a safe and reliable approach and satisfactory results of treatment in femoral head fractures. Using 3D printed model for the fracture of the femoral head, the fracture can be viewed in every direction to provide an accurate description of fracture characteristics, which contributes to make a reasonable surgical plan for patients. In addition, the 3D printing-based Ganz approach can obtain excellent surgical exposure and protection of the femoral head blood supply, reduce the operation time and intraoperative blood loss, make the precise osteotomy, anatomically fix the intra-articular fragments, and effectively reduce postoperative complications.

Comparison of the modified Heuter approach and the Kocher-Langenbeck approach in the treatment of Pipkin type I and type II femoral head fractures.

PURPOSE: To evaluate and compare the effectiveness of the modified Heuter approach and the Kocher-Langenbeck approach in the treatment of Pipkin type I and II femoral head fractures. METHODS: The study cohort consisted of 39 patients with Pipkin type I or type II femoral head fractures who were treated by open reduction and internal fixation through the modified Heuter approach (the Heuter group) or the Kocher-Langenbeck approach (the K-L group) between June 2013 and January 2016. Standard radiographs and computed tomography (CT) scans were obtained before surgery and during the follow-up. The two approaches were compared in reference to operative time, amount of blood loss, the occurrence of complications, and final functional outcome. The Brooker classification was used to document heterotopic ossification and the Thompson-Epstein scores were used for final evaluation. RESULTS: The mean operative time and estimated blood loss in the Heuter group were lower than those in the K-L group (P < 0.001 for both measures). The incisions healed primarily in all patients after surgery, no infection or deep venous thromboses were detected in either group, post-operative imaging data showed that dislocation and fractures were reduced, and the fractures finally achieved bony union. There were no significant differences in the incidence of complications or final functional outcomes between the two groups. CONCLUSIONS: Compared with the Kocher-Langenbeck approach, the modified Heuter approach can effectively reduce the blood loss and operative time without increasing the risk of complications; this approach is simple, straightforward, and atraumatic and may be a viable option for open reduction and internal fixation of Pipkin type I and type II femoral head fractures.

Middle-term follow-up results of Pipkin type IV femoral head fracture patients treated by reconstruction plate and bioabsorbable screws.

PURPOSE: To investigate the mid-term curative effects of the treatment of Pipkin type IV femoral head fractures using a reconstruction plate and bioabsorbable screws and provide the evidence for clinical practice. METHODS: From February 2010 to September 2014, 21 patients with Pipkin type IV femoral head fractures were treated surgically. There were 13 males and 8 females with an average age of 41.1 years (range, 20-65 years). The causes of the fractures included traffic accidents (13 cases), falls from a height (four cases), heavy lifting injuries (three cases), and sport injury (one case). All patients were followed up with radiography and three-dimensional reconstruction computed tomography and other checks and any complications were actively managed. Closed reduction of fracture-dislocation of the hip was attempted under general anesthesia using the Kocher-Langenbeck approach. Femoral head fractures were treated with internal fixation or excision based on the size of the fracture fragments, whereas acetabular fractures were fixed with a reconstruction plate and screws following anatomic reduction. RESULTS: The incisions healed by primary intention in all patients after surgery, without any infection, deep venous thrombosis, or other complications. All 21 patients were followed up for 36-76 months, with an average follow-up duration of 49 months. Postoperative imaging data showed that all dislocations and fractures were anatomically reduced, and bony union of the fractures was achieved. Heterotopic ossification was found in four patients, post-traumatic osteoarthritis in three, and avascular necrosis of the femoral head in two. At the final follow-up, the assessment of hip joint function according to the Thompson-Epstein scoring scale was excellent in 10 cases, good in six cases, fair in three cases, and poor in two cases. The rate of excellent and good functional outcomes was 76.1%. CONCLUSION: The mid-term curative effects of a reconstruction plate and bioabsorbable screws in the treatment of Pipkin type IV femoral head fractures is significant, and such the treatment can significantly improve the patient's joint function and quality of life.

There is no definitive treatment suggested in literature for Pepkin fracture. In this work, a case with class IV Pipkin fracture is presented. Fixation of the fracture was done and the outcomes of the surgical procedure immediately and 6 years after surgery are documented.

Prosthesis selection and complication treatment in elderly femoral neck fractures / 中国组织工程研究

BACKGROUND:Elderly patients with femoral neck fractures have poor regulatory mechanism, accompanied by a variety of comorbidities and complications, so the treatment and rehabilitation of perioperative femoral neck fracture is very important. OBJECTIVE:To review the prosthesis selection and complication treatment in perioperative femoral neck fracture in elderly patients. METHODS:A computer-based research was conducted in PubMed database and CNKI database for the articles published since 2000, the key words were“elderly, femoral neck fracture, perioperative, treatment and rehabilitation, hip fracture”in Chinese and English. The clinical researches were selected. The subjects were the femoral neck fracture patients with the age over 65 years. The review literatures and the literatures with smal cases and old were eliminated, and final y 20 literatures were included for analysis. RESULTS AND CONCLUSION:Due to the osteoporosis of the elderly patients, the internal fixation often failed. For the Garden Ⅲ and Ⅳ femoral neck fracture patients with the age over 65 years, as long as there is no clear contraindication for surgery, the hip replacement is often used for the treatment. The tolerance of the patients should be accurately evaluated before replacement, and the blood pressure, blood glucose and various medical complications should be control ed;the rehabilitation training after replacement is also essential. The common complications in elderly patients after replacement include stress ulcer, deep venous thrombosis, neuropsychiatric symptoms, urinary tract infections and the surgical infection.

Fracturas de la cabeza femoral: ¿corresponden a lesiones catastróficasde la cadera? / Femoral head fractures: are they catastrophic hip injuries?

Objective: To describe the clinical results and complications of patients with femoral head fractures using the Pipkin classification. Materials and Methods: Retrospective and descriptive study. We analyzed the cases of femoral head fractures treated between 1992 and 2008. Medical history of hip surgery, associated injuries, Pipkin classification, type of treatment and complications were recorded from patients medical history. Results: We report 18 cases of femoral head fractures with clinical follow-up averaged 10.3 years (range from 2.3 to 18.7 years). 14 (78 percent) males with a mean age of 44.8 years without previous history of hip disease. In 17 (95 percent) patients the mechanism of injury was a traffic accident. Associated with posterior dislocation in 17 (94 percent) and anterior dislocation in 1 (6 percent) patient. 13 cases required closed reduction, 4 open reduction and in one case primary total hip arthroplasty was performed because of associated cervical hip fracture. There were 5 (28 percent) fractures Pipkin I, 4 (22 percent) Pipkin II, 1 (6 percent) Pipkin III and 8 (44 percent) Pipkin IV. Within the overall complication rates in our series, we had no cases of heterotopic ossification, there were 3 cases of postraumatic arthritis (16.5 percent) and 5 cases of femoral head avascular necrosis (27.5 percent). Seven patients (37.5 percent) required total hip arthroplasty during their evolution. Patients Pipkin III and IV were those with the highest complication rates, requiring total hip arthroplasty in 66 percent of cases. Conclusion: The fractures of the femoral head are associated with high energy mechanisms, generally with hip dislocation and present complications with significant impact for the patient’ship, becoming a catastrophic injury when they correspond to Types III and IV of Pipkin Classification.
