Surgical treatment of benign osteolytic lesions in the femoral head and neck: a systematic review.

ABSTRACT:

Background and objectives

Treatment of benign osteolytic lesions in the femoral head and neck can be extremely challenging, particularly in children with open physis or for aggressive tumors with pathological fracture. There remains the difficult management decision as to whether to perform complete excision of the involved area or only curettage. Moreover, there is no agreed consensus on the optimal approach to lesion access when performing curettage, which included the transcervical, open and direct approach. The current systematic review aims to provide guidance for selection of surgical methods in clinical practice by comparing the advantages and drawbacks of different procedures.

Methods

A comprehensive literature search of PubMed, Embase and Web of Science databases were executed for human studies restricted to the English language. The search was filtered to include studies published from January 1980 to January 2020.

Results

A total of 33 articles including 274 patients were enrolled in the final analysis. The most common diagnosis was chondroblastoma (CBT) (104, 38.0%), followed by giant cell tumor (GCT) (56, 20.4%). There were 57 (20.8%) patients with pathological fracture. Intralesional curettage was performed in 257 (93.8%) patients with the local recurrence of 12.5% at the mean follow-up of 51.5 months. The patients who were presented with open physis or curetted via transcervical approach developed higher local recurrence in patients with CBT (P < 0.001). The local recurrence rate of GCT is 33.3% after curettage, while 8 of 9 (88.9%) patients with fracture were treated successfully with joint preservation. Two of 45 (4.4%) patients developed avascular necrosis (AVN) of femoral head after surgical hip dislocation. The reported Musculoskeletal Tumor Society (MSTS) Score was comparable among patients with different approaches to curettage.

Conclusion

The majority of benign osteolytic lesions in the femoral head and neck can be treated with intralesional curettage with acceptable local tumor control and satisfactory function. The incidence of local recurrence might be decreased dramatically for lesion access under direct visualization. The native joint maintenance could be achieved even in patients with aggressive lesions presenting pathological fracture.

Project description:Background: Femoral head fractures are rare injuries with or without traumatic dislocations. The management of these fractures is crucial to prevent the development of severe complications and to achieve optimal functional outcomes. Wide treatment options for Pipkin 1 femoral head fractures range from fragment excision, fixation following open reduction with internal fixation, or conservative treatment such as close reduction alone after fracture dislocation. However, the best decision making remains controversial not only due to lack of large trials, but also inconsistent results reported. Therefore, we aim to compare the operative with nonoperative outcomes of Pipkin type 1 patients. Patients and Methods: We systemically searched MEDLINE, EMBASE, Cochrane library, In-Process & Other Non-Indexed Citations to identify studies assessing outcomes of Pipkin type 1 patients after conservative treatment, and open reduction with excision or fixation. Data on comparison of clinical outcomes of each management were extracted including arthritis, heterotopic ossification (HO), avascular necrosis (AVN), and functional scores (Thompson Epstein, Merle' d Augine and Postel Score). We performed a meta-analysis with the available data. Results: Eight studies (7 case series and 1 RCT) were included in this study. In a pooled analysis, the overall rate of arthritis was 37% (95% CI, 2-79%), HO was 20% (95% CI, 2-45%), and AVN was 3% (95% CI, 0-16%). In comparison of management types, the excision group reached the best functional outcomes including Thompson Epstein Score (poor to worse, 9%; 95% CI, 0-27%) and Merle d' Aubigne and Postel Score (poor to worse, 18%; 95% CI, 3-38%); ORIF group had the highest AVN rate (11%; 95% CI, 0-92%); conservative treatment had the highest arthritis rate (67%; 95% CI: 0-100%) and lowest HO rate (2%; 95% CI, 0-28%). Discussion: This meta-analysis demonstrates that different procedures lead to various clinical outcomes: fragment excision may achieve better function, conservative treatment may result in a higher arthritis rate, while ORIFs may have a higher AVN rate. These findings may assist surgeons in tailoring their decision-making to specific patient profiles. Future RCTs with multicenter efforts are needed to validate associations found in this study.

Project description:ObjectivesThe use of non-adhesive gel-like embolic materials (NAGLEMs) in the endovascular treatment of hypervascularized formations in the head and neck is gaining in popularity because of a number of important characteristics involved. Their primary benefits are their capacity to penetrate diseased vasculature, effectively distribute, and, most importantly, remain controllable during the process. We reviewed the literature and evaluated the results of using NAGLEMs in comparison to other embolizing substances (namely, coils, glue, and particles) as alternative embolizing agents for patients receiving care at our clinic. The process comprised evaluating the safety, effectiveness, and technological elements of endovascular therapy used to treat two categories of hypervascular pathological abnormalities that were surgically corrected between 2015 and 2023. Arteriovenous malformations (AVMs) located in the head, neck, and paragangliomas with jugular/carotid body localization are combined by intense shunting blood flow and shared requirements for the embolic agent used in endovascular treatment (such as penetration, distribution, delayed polymerization, and controllability). An analysis of the literature was also conducted. Results showed 18 patients diagnosed with neck paragangliomas of the carotid body and jugular type. Five patients with arteriovenous malformation (AVM) of the face and neck were included, consisting of sixteen females and seven males with an average age of 55 ± 13 years. Endovascular procedures were performed using NAGLEMs (ONYX (Medtronic, Irvine, CA, USA), SQUID (Balt, Montmorency, France), and PHIL (Microvention, Tustin, CA, USA)) and dimethyl sulfoxide (DMSO)-compatible balloon catheters. All patients achieved complete or partial embolization of hypervascularized formations using one or more stages of endovascular treatment. Additionally, three AVMs of the face and two paragangliomas of the neck were surgically excised following embolization. In other instances, formations were not deemed necessary to be removed. The patients' condition upon discharge was assessed by the modified Rankin Scale (mRs) and rated between 0 and 2.ConclusionCurrently, NAGLEMs are predominantly used to treat hypervascularized formations in the neck and head due to their fundamental properties. These properties include a lack of adhesion and a delay in predictable polymerization (after 30-40 min). NAGLEMs also exhibit excellent distribution and penetration throughout the vascular bed of the formation. Adequate controllability of the process is largely achieved through the presence of embolism forms of different viscosity, as well as excellent X-ray visualization.

Project description:BackgroundFemoral head fractures are rare injuries; incongruency and instability are indications for surgical intervention. Anterior, posterior, and transtrochanteric surgical approaches have been proposed, but the exposure is limited with classical approaches. Surgical hip dislocation allows for a 360° view of the head and may facilitate a reduction in selected head fractures, but to our knowledge, few studies have reported on the results with this technique. We therefore report on the (1) quality of fracture reduction; (2) modified Harris hip score at a minimum of 2 years (mean, 6 years, range, 26-122 months); and (3) frequency of complications, including avascular necrosis (AVN), arthritis development, and heterotopic ossification, in a case series of patients with femoral head fractures treated with this approach.Description of techniqueThe procedure involves digastric trochanteric flip osteotomy and safe dislocation of the femoral head, preserving its vessels. Using this technique we are able to reduce all displaced femoral head fractures under direct view. Definitive fixation is performed through this approach with 2.7-mm nonabsorbable screws. The same technique may be used also for Pipkin IV fractures to fix transverse, T-type, posterior wall, or posterior column acetabular fracture.MethodsBetween 2004 and 2011, we used this approach to manage all displaced femoral head fractures in patients younger than 55 years old. A total of 17 patients were thus treated; of those three were lost to followup before 2 years, and one was excluded from study because of severe preoperative neurological impairment, leaving 13 for analysis here. Patient demographic, injury, and surgical variables as well as complications were recorded and retrospectively evaluated. Radiographic outcome was scored according to Matta's criteria on postoperative radiographs. Outcomes were evaluated with the modified Harris hip score. Minimum followup was 24 months (mean, 77 months; SD, 32.8 months).ResultsFracture reduction was anatomic in eight hips and imperfect in five. Mean clinical score was 82 points (SD, 7.7). One patient developed symptomatic femoral head AVN and underwent total hip arthroplasty 4 years after the index procedure; no other patient underwent arthroplasty. Besides this patient, signs of arthritis (Grade I according to Tönnis classification) were found in one patient and heterotopic ossification was recorded in two patients, but neither was symptomatic.ConclusionsOur experience with surgical dislocation shows clinical results comparable to previously reported outcomes in femoral head fractures treated with common approaches; we also present a similar rate of AVN and a lower rate of posttraumatic arthritis, but a higher risk of heterotopic ossification. Further case-control studies are necessary to confirm these statements.Level of evidenceLevel IV, therapeutic study.
