“…A recent review study recommends internal stabilization for big cystic lesions in the proximal femur. 15 In our case cystic lesion was involving trochanteric area with extension into calcar portion of the neck as well as subtrochanteric area hence surgical treatment with extended curettage, auto-allo bone grafting with use of fibula strut for supporting calcar portion of neck and supplementary buttress plate fixation was done. Bone graft was well taken up in the follow up and excellent functional outcomes were seen in the follow up.…”

“…Our outcome findings are concurrent with the current literature. 11,15 There is paucity in literature on the treatment of large peritrochanteric cysts, and only few studies have evaluated the use of intralesional extended curettage with a fibular strut. 16,17 However, several studies have reported successful outcomes with curettage and bone grafting for these tumors.…”

Simple bone cysts are benign bone lesions commonly found in children and adolescents. They are usually asymptomatic and are incidentally detected on imaging studies. However, in rare cases, simple bone cysts can grow to a large size and cause symptoms such as pain and functional limitations. We present a case report of a large peritrochanteric simple bone cyst in an adolescent male who presented with hip pain and difficulty in walking. The diagnosis was confirmed by radiographic findings and histopathological examination of the cyst. The patient was managed with curettage and auto allo bone grafting with fibular strut and supplementary plate fixation. Patient had a favourable outcome with complete resolution of symptoms at 18-month follow-up. Our case report highlights the need of fixation for large simple bone cyst in proximal femur region along with curettage and bone grafting.

ObjectiveA retrospective study was conducted to compare the mid-term clinical efficacy between percutaneous calcium sulfate injection (PCSI) and localized scrape bone grafting (LSBG) in using titanium elastic nails treat humerus pathologic fractures caused by unicameral bone cysts in children.MethodsHumerus pathologic fracture patients with unicameral bone cysts in our pediatric orthopedic department from January 2015 to January 2020 were retrospectively analyzed. Patients were divided into two groups, namely the PCSI group and the LSBG group, based on the type of bone grafting material they received. Preoperative assessments were made in both groups using the Cyst Index and Cyst activity. During the perioperative phase, assessments were made regarding operative time, bleeding, postoperative VAS scores, and the frequency of reoperation within 2 years. Clinical outcomes were evaluated using the Capanna scale at the last follow-up, and the occurrence of re-fractures during the follow-up period.ResultsA total of 22 patients were included, with a mean follow-up duration of 33.5 ± 5.8 months. No significant differences were found between the two groups in terms of Cyst Index and Cyst activity before the operation. The operative time, bleeding, and postoperative VAS scores in the PCSI group were found to be lower than those in the LSBG group (P < 0.05). The PCSI group also showed a higher frequency of reoperation within 2 years compared to the LSBG group (P < 0.05). However, no significant differences were observed between the two groups in terms of Capanna scale scores at the last follow-up and the incidence of re-fractures during follow-up.ConclusionsBoth titanium elastic nails (TEN) combined with PCSI or LSBG were found to be safe and effective treatments for humerus pathologic fractures caused by unicameral bone cysts in children. PCSI is considered as a less invasive option with shorter operative times, less bleeding, and reduced postoperative pain, although it comes with the risk of multiple injections. On the other hand, LSBG is considered as a more invasive option for the treatment of active bone cysts but is associated with a lower recurrence rate.

“…Possible interventions for these patients include methylprednisolone injections, applications of autologous bone marrow, or a combination of demineralized bone matrix with bone marrow [ 4 ]. It is recognized that UBCs in the pertrochanteric region or those with significant enlargement (where the transverse diameter exceeds 85% or there is less than 0.55 mm of cyst wall remaining during follow-up) necessitate surgical treatment [ 5 ]. For those at risk of pathological fractures, ensuring stable fixation, decompressing, and breaking the cyst wall to facilitate bone marrow penetration into the cavity are paramount.…”

Background Unicameral bone cysts (UBCs) are benign tumor-like lesions that are the most common cause of pathological proximal femur fracture in children. This study aimed to present the outcomes of acute, unstable, pathological proximal femur fractures secondary to UBCs in children. Material/Methods We retrospectively reviewed data on 12 patients with a mean age of 9.3 years (7–12 years) who were initially treated with decompression and grafting, followed by stabilization using a 120° fixed-angle low-contact locking pediatric plate (LCLPP). The Musculoskeletal Tumor Society (MSTS) scores, Capanna classification of cyst repair, time to union, collodiaphyseal angle (CDA), and limb length discrepancy (LLD) were evaluated. Results The mean follow-up was 33.1 months (range, 13–96 months). The mean union time was 9.5 weeks (8–14 weeks). The mean time for reparation of the cyst was 6.9 months (range 3–9 months). Four patients had Dormans type IB, while the remaining had type IIB fractures. According to the Capanna classification, repairs in 10 cases were grade I and in 2 cases grade II. At the last follow-up, the mean 120.8° of preoperative CDA was corrected to 140.9° ( P <0.001) and there was no difference compared to the healthy side ( P =0.214). The mean postoperative MSTS score was 97.1% (29.1 points). Two patients experienced LLD at the affected extremities, while the other 10 patients healed without any complications. Conclusions Fixation of acute unstable fractures secondary to UBCs with a 120 ° fixed-angle LCLPP is a reliable and successful option after decompression and grafting of the lesion.
