The bladder exstrophy-epispadias complex includes some of the most challenging conditions treated by pediatric urologists. They are associated with the need for multiple intricate reconstructive procedures, aimed at restoring the anatomy and function of the bladder, urethra and external genitalia. These patients often endure multiple redo reconstructive procedures to improve urinary function, sexual function and cosmesis throughout the first two decades of life. In this article, we present the 30-year experience of a single surgeon performing redo surgery for males born with epispadias and bladder exstrophy. Through detailed documentation of 6 clinical cases, we highlight technical aspects that may contribute to a successful surgical reconstruction in these patients. The article is focused specifically on patients undergoing redo epispadias repair with or without concomitant continence procedures. We make the case for complete penile disassembly with external rotation of the corpora to correct recurrent dorsal curvature; this approach also allows the surgeon to have access to the proximal urethra and bladder neck after opening the intersymphiseal scar/band. This is useful when additional procedures on the bladder, such as bladder neck tailoring, are necessary. We also highlight the importance of avoiding reverse Byars\' flaps when performing skin closure, due to the resulting midline scar. Besides being associated with a poor cosmetic outcome, it can also contribute to recurrent dorsal curvature. The authors advocate for rotational skin flaps to cover the penile shaft. Correction of dorsal curvature and improved cosmesis obtained with complete penile disassembly sometimes comes at the expense of the urethra being left as a hypospadias (figure). This will require further surgeries (usually a 2-stage buccal mucosa graft), much like the treatment of proximal hypospadias. Redo epispadias surgery in males remains a challenge. The systematic approach offered by the case scenarios may help guide surgeons dealing with this difficult condition. Patient with complications after repair of classic bladder exstrophy.

UNASSIGNED: This study aimed to demonstrate the feasibility of lag screw exchange for painful lateral soft tissue impingement in patients initially treated with cephalomedullary nailing (CMN) for an intertrochanteric hip fracture.
UNASSIGNED: Ten patients initially treated with CMN for unstable intertrochanteric fractures presenting with persistent pain and radiographic evidence of lag screw lateral migration were treated with exchange of original screw with shorter lag screw buried in the lateral cortex to prevent impingement. Patients were evaluated for resolution of pain and achievement of pre-fracture ambulatory status at 6 months post-operatively.
UNASSIGNED: Average age was 71.5 years (range: 62-88). Average length of follow-up was 24.9 months. All patients were female, with an average Charlson Comorbidity Index of 1.0 (0-3) and average Body Mass Index of 22.2 (16.0-31.1). Five of ten patients (50.0%) were treated with a cortisone injection in the trochanteric bursa prior to screw exchange with temporary pain relief. Five (50.0%) patients presented with limited range of hip motion. Five (50.0%) had history of prior or current bisphosphonate use. Average lag screw prominence was noted to be 12.2mm (7.9-17.6mm) on radiographic evaluation. Screw exchange was performed at an average of 18.6 months (5.4-44.9 months) following the index procedure. Average operating time of the screw exchange procedure was 45.3 minutes (34-69 minutes) and blood loss was <50mL in all cases. Replacement lag screws were an average of 16.0mm (10-25mm) shorter than the initial screw. All patients achieved complete or significant resolution of lateral thigh pain, and nine (90%) returned to pre-fracture ambulatory status by eight weeks after screw exchange. All patients remained pain free at six months after screw exchange.
UNASSIGNED: Lag screw exchange is a efficacious method to address the mechanical irritation of laterally protruding lag screws following IT hip fracture, while also prophylaxing against subsequent femoral neck fractures. Level of Evidence: IV.

UNASSIGNED: A 60-year-old female underwent proximal tibial autograft harvest for a Cotton osteotomy. Her postoperative course was complicated by psychogenic non-epileptic seizure (PNES) episodes leading to unintentional weightbearing. Knee radiographs at 6 weeks post-procedure demonstrated a displaced proximal tibia fracture through the autograft harvest site. Further clinical review revealed metabolic derangements consistent with secondary hyperparathyroidism. Initial nonoperative treatment led to atrophic varus nonunion requiring definitive treatment with total knee arthroplasty with revision components.
UNASSIGNED: This case describes a rare complication of proximal tibial autograft harvest and highlights the importance of preoperative metabolic workup and bone health optimization.Level of Evidence: IV.

OBJECTIVE: This study aims to assess time trends in case-mix and to evaluate the risk of revision and causes following primary THA, TKA, and UKA in private and public hospitals in the Netherlands.
METHODS: We retrospectively analyzed 476,312 primary arthroplasties (public: n = 413,560 and private n = 62,752) implanted between 2014 and 2023 using Dutch Arthroplasty Register data. We explored patient demographics, procedure details, trends over time, and revisions per hospital type. Adjusted revision risk was calculated for comparable subgroups (ASA I/II, age ≤ 75, BMI ≤ 30, osteoarthritis diagnosis, and moderate-high socioeconomic status (SES).
RESULTS: The volume of THAs and TKAs in private hospitals increased from 4% and 9% in 2014, to 18% and 21% in 2022. Patients in private hospitals were younger, had lower ASA classification, lower BMI, and higher SES compared with public hospital patients. In private hospitals, age and ASA II proportion increased over time. Multivariable Cox regression demonstrated a lower revision risk for primary THA (HR 0.7, CI 0.7-0.8), TKA (HR 0.8, CI 0.7-0.9), and UKA (HR 0.8, CI 0.7-0.9) in private hospitals. After initial arthroplasty in private hospitals, 49% of THA and 37% of TKA revisions were performed in public hospitals.
CONCLUSIONS: Patients in private hospitals were younger, had lower ASA classification, lower BMI, and higher SES com-pared with public hospital patients. The number of arthroplasties increased in private hospitals, with a lower revision risk compared with public hospitals.

METHODS: A patient underwent revision of a total knee replacement to a cementless rotating-hinge prosthesis. The femoral component became loose, but due to the patient\'s frailty and cognitive decline, revision was not performed. Subsequently, the yoke failed, dissociating the femoral and tibial components, necessitating a single-stage revision.
CONCLUSIONS: This case underlines the need for robust fixation of components of rotating-hinge knee replacements to avoid mechanical failures. It contributes valuable insights to the limited literature on yoke failure in total knee arthroplasty, emphasizing the importance of implant design, patient selection, and surgical technique to prevent such complications.

UNASSIGNED: Reoperations are part of neurosurgical practice. In these cases, an already formed craniotomy seems the most logical and appropriate. However, reoperations via large approaches can be quite traumatic for the patient. Then minimally invasive approaches, being less traumatic, can be a good alternative.
UNASSIGNED: We describe 7 consecutive patients who underwent reoperations using minimally invasive approaches in the areas of conventional craniotomies. Surgical Theater® visualization platform was used for preoperative planning. The study evaluated the size of surgical approach, surgical efficacy, and the presence of complications.
UNASSIGNED: The size of a minimally invasive craniotomy was significantly smaller than that of a conventional approach. The preoperative goals were achieved in all described cases. There were no complications in the early postoperative period. Although the anatomy of the operated brain region in reoperations is altered, keyhole approaches can be successfully used with the support of preoperative planning and intraoperative neuronavigation. Given that the goals of reoperations may differ from those of the primary surgery, and a large approach is more traumatic for the patient, minimally invasive craniotomy can be considered as a good alternative. The successful use of minimally invasive approaches in areas of conventional craniotomies reinforces the philosophy of keyhole neurosurgery. In cases where goals can be achieved using small approaches, it makes no sense to use large conventional ones.
UNASSIGNED: Minimally invasive approaches can be successfully used during reoperations in patients after conventional craniotomies.

UNASSIGNED: Many techniques exist to reapproximate a cleft lip but can leave unsatisfactory results with nonanatomic scars and a short upper lip, creating a need for revision. Many revisions focus on adjacent tissue transfers and realignment of landmarks, but in the senior authors\' experience, recreating the defect and utilizing the Fisher repair for revision have led to aesthetically pleasing results and less noticeable scars. A database was collected that included all cleft lip revisions performed at a large, comprehensive children\'s hospital from October 2018 to July 2021. Inclusion criteria included any cleft patient with a cleft lip revision performed by two craniofacial surgeons. Data collected included sex, characteristics of the cleft lip, age at initial and index repair, type of initial repair, previous revisions, type of revision with any additional tissue rearrangement, and any nose repair. Sixty-five patients were included in the study for analysis. The type of initial repair was known in sixty-four cases (98%), and fifty-four were Millard repairs (83%). Twenty-two patients (33%) had a previous revision prior to their index revision. Sixty patients (92%) underwent the Fisher repair technique for their index revision and forty-six patients (70%) underwent nasal revision. In follow-up, all patients demonstrated an improvement in lip aesthetics. This study demonstrates a large subset of patients that have undergone cleft lip revision using the Fisher technique. In the senior surgeons\' experience, the Fisher repair technique in the setting of cleft lip revision is an ideal way to address the shortcomings of historical repair techniques.

BACKGROUND: Surgical treatment for hinge failure in mega-prosthesis continues to be a challenge. This study introduces a new method for treating hinge failure by using a unilateral prosthesis and hinge revision.
METHODS: We here present two patients who underwent mega-prosthesis reconstruction after resection of osteosarcoma in the distal femur. To address the issue of knee hyperextension after mega-prosthesis reconstruction, one patient underwent three revision surgeries, two surgeries were performed using the original hinge, and one surgery involved a newly designed hinge. To resolve the problem of dislocation, one patient underwent three revisions, with the first two revisions not involving hinge replacement and the third revision involving a newly designed hinge. Two replacements of unilateral prosthesis and hinge renovations were successful.
CONCLUSIONS: Unilateral prosthesis and newly designed hinge device revision are effective in treating the failure of old-fashioned mega-prosthesis hinges.

BACKGROUND: Ventriculoperitoneal (VP) shunt insertion is a means of diverting cerebrospinal fluid (CSF) for management of hydrocephalus. Revision rates, operating time, and length of stay (LOS) following laparoscopic insertion of the distal catheter have been mixed. There are limited data on the role of adhesiolysis during VP shunt insertion. Valve characteristics have also been shown to influence patient outcomes. There is a paucity of Australian data reporting on the effect of these variables on shunt outcomes. We aimed to study patient demographics, indications, and surgical and instrument variables in the Australian context.
METHODS: We performed a retrospective, multi-surgeon, single-centre analysis of VP shunts inserted in adults via an open or laparoscopic technique. Data on patient demographics and surgery characteristics were collected from the hospital medical records and the Australasian Shunt Registry. The primary outcome was shunt revision rate and secondary outcomes were postoperative complications, operating time and LOS, and shunt survivability.
RESULTS: Fifty-six participants were eligible for analysis. The overall revision rate was 14.3 %, which was lower than the national average. The distal catheter revision rate was 0 %. Laparoscopic insertion of the distal catheter was shown to significantly reduce operating time (70.4 min in the open group and 50.7 min in the laparoscopic group, p < 0.001). This was demonstrated across different aetiologies, and when controlling for age and valve-type (p < 0.05). The revision rate of non-programmable was higher than programmable valves (42.9 % versus 2.9 %, respectively). There were no differences between previous abdominal surgery, LOS, complication, or revision rate between open and laparoscopic insertion. VP shunt survivability was greater in the laparoscopic group (90-day shunt survival of 96.7 % and 92 % in the laparoscopy and open groups, respectively; p > 0.05). We did not find any significant difference in operating time or length of stay for age, sex, or previous abdominal surgery, even when accounting for surgical technique. Indication and shunt survivability varied widely between age groups. The use of laparoscopic insertion increased over time, though surgeons did not crossover techniques.
CONCLUSIONS: The overall distal revision rate of VP shunts is low. Laparoscopic insertion of the distal catheter reduces operating time and may improve shunt survivability. Larger studies are needed to confirm differences in shunt survivability in open versus laparoscopic distal catheter insertion, between age groups, clinical indications, and valve type on patient outcomes.

UNASSIGNED: Satisfactory clinical results of meniscal allograft transplantation (MAT) have been reported in recent years. However, it remains unclear whether the clinical outcomes of MAT when combined with an osteotomy are inferior to those of isolated MAT.
UNASSIGNED: To compare the survival rates and clinical outcomes of patients who received isolated medial MAT with those of patients undergoing medial MAT combined with high tibial osteotomy (HTO).
UNASSIGNED: Cohort study; Level of evidence, 3.
UNASSIGNED: A total of 55 patients underwent arthroscopic medial MAT using the soft tissue technique and HTO (mean age, 41.3 ± 10.4 years; 9 female); after fuzzy case-control matching on demographics, 55 controls who underwent isolated medial MAT were also included. Survival analyses were performed using the Kaplan-Meier method with surgical failure, clinical failure (Lysholm score, <65), and reoperation as endpoints. Subjective clinical scores were collected preoperatively and at the final follow-up.
UNASSIGNED: The mean follow-up time was 5.4 years, up to 8 years. All outcomes significantly improved at the last follow-up (P < .001). No differences were identified between MAT and MAT + HTO groups preoperatively and at the last follow-up (P > .05). At the final follow-up, 8 of 55 (14.5%) of the MAT + HTO patients and 9 of 55 (16.4%) of the MAT patients had a Lysholm score <65 (P = .885). Overall, 90% of the patients declared they would repeat the surgery regardless of the combined procedure. Surgical failure was identified in 6 of 110 (5.5%) patients: 5 of 55 (9.1%) in the MAT + HTO group and 1 of 55 (1.8%) in the MAT group (P = .093). Clinical failure was identified in 19 of 110 (17.3%) patients: 11 of 55 (20%) in the MAT + HTO group and 8 of 55 (14.5%) in the MAT group (P = .447). A significantly lower survivorship from surgical failure was identified in the MAT + HTO group (hazard ratio, 5.1; P = .049), while no differences in survivorship from reoperation and clinical failure were identified (P > .05).
UNASSIGNED: Patients undergoing medial MAT + HTO showed similar clinical results to patients undergoing isolated medial MAT at midterm follow-up, and thus a surgically addressed malalignment does not represent a contraindication for medial MAT. However, the need for a concomitant HTO is associated with a slightly higher failure rate over time.
