To assess the viability of virtual reality (VR) technology in conjunction with femoral head reduction plasty for the treatment of coxa plana, and to determine its therapeutic efficacy.
The research team selected three male patients, each diagnosed with coxa plana and between the ages of 15 and 24, for their study, which encompassed the timeframe between October 2018 and October 2020. Preoperative surgical planning for the hip joint incorporated VR technology. 3D imaging was generated from 256 CT scan slices of the hip to simulate the operation and establish the anatomical correspondence between the femoral head and acetabulum. Preoperative planning dictated the surgical procedure, which entailed reduction plasty of the femoral head under surgical dislocation, relative lengthening of the femoral neck, and periacetabular osteotomy. The reduction in the size of the femoral head osteotomy, along with the rotation angle of the acetabulum, was verified through C-arm fluoroscopy. The osteotomy's healing process was evaluated radiologically following the operation. Prior to and subsequent to the surgical procedure, the Harris hip function score and VAS score were recorded. X-ray film analysis provided the measurements of femoral head roundness index, center-edge angle, and femoral head coverage.
Three operations were completed successfully, with operational times of 460, 450, and 435 minutes, and respective intraoperative blood losses of 733, 716, and 829 milliliters. Following surgery, all patients received an infusion of 3 U of suspension oligoleucocyte and 300 mL of frozen, inactivated virus plasma. The patient experienced no infections or deep vein thrombosis, which are common postoperative complications. Three patients were observed for periods of 25, 30, and 15 months, respectively, after initial presentation. At three months post-surgery, the CT scan revealed satisfactory osteotomy healing. Improvements in the VAS and Harris scores, femoral head rounding index, hip CE angle, and femoral head coverage were substantial at the 12-month post-operative mark and final follow-up, compared to the preoperative values. The Harris score, taken 12 months post-surgery, demonstrated excellent hip function for all three patients.

Assessing the impact of full bone tumor excision in the pelvic zone, alongside reconstruction with an allogeneic pelvis, a modular prosthetic device, and a bespoke 3D-printed implant.
Retrospective analysis encompassed the clinical details of 13 patients with primary bone tumors in the pelvic region, undergoing both tumor resection and acetabular reconstruction procedures between March 2011 and March 2022. selleck kinase inhibitor Consisting of 4 men and 9 women, the average age of the group was 390 years, with ages ranging from 16 years old to 59 years old. Among the diagnoses, four were giant cell tumors, five were chondrosarcomas, two were osteosarcomas, and two were Ewing sarcomas. A study of pelvic tumors, utilizing the Enneking classification, found that four cases presented involvement in zone one, four cases were identified in zones two and three, and five cases encompassed both zones four and five. The disease's course, in terms of duration, extended from a minimum of one month to a maximum of twenty-four months, averaging ninety-five months. A systematic follow-up procedure was implemented to monitor for tumor recurrence and metastasis, and concomitant imaging examinations were conducted to analyze implant condition, examining for fractures, bone resorption, bone nonunion, and other complications. The preoperative and one-week postoperative visual analogue scale (VAS) scores were used to assess hip pain improvement. The recovery of hip function was measured using the Musculoskeletal Tumor Society (MSTS) scoring system after the surgical procedure.
The operative time was four to seven hours, averaging forty-six hours; intraoperative blood loss ranged from eight hundred to sixteen hundred milliliters, averaging twelve thousand milliliters. selleck kinase inhibitor Post-operative monitoring revealed no instances of re-intervention or patient demise. Patients' follow-up spanned from nine to sixty months, with a mean duration of 335 months. selleck kinase inhibitor During the follow-up period, no instances of tumor metastasis were observed in four patients undergoing chemotherapy. A postoperative wound infection manifested in one patient, and one patient also suffered prosthesis dislocation within one month following prosthesis replacement. Twelve months post-surgical intervention, a reoccurrence of giant cell tumor was seen; puncture biopsy demonstrated malignant conversion, prompting hemipelvic amputation. Following the hip surgery, postoperative pain was significantly reduced, with a Visual Analog Scale (VAS) score of 6109 recorded one week post-operation. This score stood in stark contrast to the preoperative VAS score of 8213.

Reconstruction of primary bone tumors situated in the pelvic zone coupled with resection can result in satisfactory hip function, and the allogeneic pelvis's interface with a 3D-printed prosthesis demonstrates improved bone integration, more closely aligning with biomechanical and biological reconstruction requirements. The procedure of pelvis reconstruction, though intricate, requires a comprehensive evaluation of the patient's health prior to the operation, and sustained follow-up is essential to assess long-term outcomes.
Primary bone tumor resection and pelvic reconstruction procedures can yield satisfactory hip joint function. The interface between allogeneic pelvic components and 3D-printed prosthetics exhibits enhanced bone ingrowth, better conforming to biomechanical and biological reconstruction requirements. Despite the complexities of pelvis reconstruction, a meticulous preoperative evaluation of the patient's overall state is imperative, and the lasting benefits of the procedure demand continued observation.
The study scrutinizes the feasibility and results of percutaneous screwdriver rod-assisted closed reduction for valgus-impacted femoral neck fractures.
In the period encompassing January 2021 and May 2022, 12 patients afflicted with valgus-impacted femoral neck fractures were managed using a percutaneous screwdriver rod-assisted closed reduction procedure complemented by the femoral neck system (FNS) for internal fixation. Consisting of 6 males and 6 females, the group had a median age of 525 years, varying between 21 and 63 years of age. Two instances of fractures were caused by traffic accidents; nine by falls; and one by a fall from a lofty height. Seven femoral neck fractures, unilateral and closed, appeared on the left, and a further five such fractures were located on the right. The journey from initial injury to surgical intervention encompassed a duration varying from 1 to 11 days, with an average duration of 55 days. Data on fracture healing duration and post-operative complications were meticulously documented. The Garden index served as the basis for evaluating the quality of fracture reduction. The Harris score, applied during the final follow-up, served as a measure of hip joint function, complemented by the quantification of femoral neck shortening.
The successful completion of all operations is a fact. Post-operative incisional fat liquefaction presented in one patient. This resolved following enhanced dressing techniques; meanwhile, the other patients' incisions healed by first intention. Each patient underwent follow-up, monitored for a period ranging from 6 to 18 months, with an average follow-up duration of 117 months. The re-examined X-ray films, assessed by the Garden index, showed a satisfactory fracture reduction grade in ten cases and an unsatisfactory grade in two. Fractures ultimately reached bony union, the recovery period spanning three to six months, on average 48 months. In the final follow-up, the femoral neck showed a decrease in length of 1-4 mm, resulting in an average shortening of 21 mm. During the follow-up period, no instances of internal fixation failure or femoral head osteonecrosis were observed. The final follow-up observation reported a hip Harris score range of 85-96, with an average of 92.4 points. Notably, ten cases were classified as excellent, and two were rated as good.
