Triple pelvic osteotomy (TPO) is a prophylactic surgical procedure performed on dogs with canine hip dysplasia. The procedure is indicated in skeletally immature dogs without secondary osteoarthritis (OA). It has been suggested that 60° of rotation is excessive and is associated with poor outcome. The objective of the study was to assess the medium term outcome in dogs having undergone triple pelvic osteotomy (TPO) using 60° dedicated plates. Nine TPOs were performed in seven dogs with hip dysplasia. Eight of nine hips had 72–100% osseous union at the time of revisit. The mean time to final radiographic recheck was 200 days (range, 185–229 days). The mean time to follow-up was 11.5 months (range 11–12 months). All 7 dogs had regained full function and did not require supplemental analgesia. Pelvic canal narrowing was noted in the two dogs with bilateral surgeries, but no clinical consequences were noted according to owner's statement.If more than 40 degrees reduction angles at Ortolani test, 60° of rotation of the acetabulum can be used successfully in dogs with hip dysplasia. At the time of mid-term follow-up, all dogs in this case series had full function.

Sternal Fractures

Background: Sternal fractures are rare, and they can be treated nonoperatively. Vertical sternal fractures have rarely been reported. Purpose: To describe the management and surgical treatment of a series of elite-level athletes who presented with symptomatic nonunions of a vertical sternal fracture. Study Design: Case series; Level of evidence, 4. Methods: Patients with an established symptomatic nonunion of a vertical sternal fracture, as diagnosed by computed tomography (CT) or magnetic resonance imaging (MRI), underwent open reduction and internal fixation using autologous bone graft and cannulated lag screws. The patients were assessed preoperatively and at the final follow-up using the Rockwood sternoclavicular joint (SCJ) score; Constant score; and shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores. Bony union was confirmed on postoperative CT scan. Results: Five patients (4 men and 1 woman) were included; all were national- or international-level athletes (rugby, judo, show-jumping, and MotoGP). The mean age at surgery was 23.4 years (range, 19-27 years), the mean time from injury to referral was 13.6 months (range, 10-17 months), and the mean time from injury to surgery was 15.8 months (range, 11-20 months). The mean follow-up was 99.4 months (range, 25-168 months). There was a significant improvement after surgery in the mean Rockwood SCJ score (from 12.6 to 14.8 [ P < .05]), Constant score (from 84 to 96.4 [ P < .05]; 80% met the minimal clinically important difference [MCID] of 10.4 points), and QuickDASH (from 6.8 to 0.98 [ P < .05]; 0% met the MCID of 15.9 points). Four of the patients were able to return to sport at their preinjury level, and 1 patient retired for nonmedical reasons. All of the fractures had united on the postoperative CT scan. There were no postoperative complications. Conclusion: Vertical fractures of the sternum are very rare and tend to behave clinically like an avulsion fracture injury to the capsuloligamentous structure of the inferior SCJ. The requirement of advanced imaging to diagnose this injury means that the actual incidence and natural history are not known. For high-demand athletes, early identification, surgical reduction, and fixation are likely to achieve the best outcome.

OBJECTIVETectal gliomas constitute a rare and inhomogeneous group of lesions with an uncertain clinical course. Because these supposedly benign tumors are frequently followed up by observation over many years, the authors undertook this analysis of their own case series in an effort to demonstrate that the clinical course is highly variable and that there is a potential for a progressive biology.METHODSClinical data analysis of 23 cases of tectal glioma (involving 9 children and 14 adults) was performed retrospectively. Radiographic data were analyzed longitudinally and MR images were evaluated for tumor volume, contrast enhancement, and growth progression. Quality of life was assessed using the EORTC BN20 and C30 questionnaires during follow-up in a subgroup of patients.RESULTSThe patients’ mean age at diagnosis was 29.2 years. The main presenting symptom at diagnosis was hydrocephalus (80%). Six patients were treated by primary tumor resection (26.1%), 3 patients underwent biopsy followed by resection (13.1%), and 3 patients underwent biopsy only (13.1%). For additional treatment of hydrocephalus, 14 patients (60.9%) received shunts and/or endoscopic third ventriculostomy. Radiographic tumor progression was observed in 47.9% of the 23 cases. The mean time between diagnosis and growth progression was 51.5 months, and the mean time to contrast enhancement was 69.7 months. Histopathological analysis was obtained in 12 cases (52.2%), resulting in 5 cases of high-grade glioma (3 cases of glioblastoma multiforme [GBM], grade IV, and 2 of anaplastic astrocytoma, grade III), 5 cases of pilocytic astrocytoma, 1 diffuse astrocytoma, and 1 ganglioglioma. Malignant progression was observed in 2 cases, with 1 case progressing from a diffuse astrocytoma (grade II) to a GBM (grade IV) within a period of 13 years. Quality-of-life measurements demonstrated distinct functional deficits compared to a healthy sample as well as glioma control cohorts.CONCLUSIONSAnalysis of this case series shows that a major subpopulation of tectal gliomas show progression and malignant transformation in children as well as in adolescents. These tumors therefore cannot be considered inert lesions and require histological confirmation and close follow-up. Quality-of-life questionnaires show that tectal glioma patients might benefit from special psychological support in emotional, social, and cognitive functionality.

Background: Osteochondral allograft (OCA) transplantation is a useful alternative for treatment of posttraumatic ankle arthritis in young patients but has a relatively high failure rate and further procedures are often required. The purpose of this study was to evaluate outcomes of patients who underwent revision OCA transplantation of the ankle after failed primary OCA transplantation. Methods: Twenty patients underwent revision OCA transplantation of the ankle between 1988 and 2015. Mean age was 44 years, 55% (11 of 20) were female. The mean time from primary to revision OCA was 3.0 ± 1.7 years. All patients had a minimum follow-up of 2 years. Outcomes included the American Academy of Orthopaedic Surgeons Foot and Ankle Module (AAOS-FAM) and questionnaires evaluating pain and satisfaction. Failure of the revision OCA was defined as a conversion to arthroplasty, arthrodesis, or amputation. Results: Ten of 20 ankles required further surgery, of which 30% (6 of 20) were considered OCA revision failures (4 arthrodeses, 1 arthroplasty, and 1 amputation). The mean time to failure was 6.7 (range, 0.6-13.1) years. Survivorship of the revision OCA was 84% at 5 years and 65% at 10 years. The 14 patients with grafts remaining in situ had an average follow-up of 10.3 years; mean AAOS-FAM Core Score was 70.5 (range, 42.3-99). Of the patients who answered the follow-up questions, 4 of 7 reported moderate to severe pain, and 5 of 12 were satisfied with the results of the procedure. Conclusion: Although the results of revision ankle OCA transplantation are not inferior to primary OCA transplantation, the high rates of persistent pain, further surgery, and graft failure suggest that the indications for OCA as a revision procedure should be carefully evaluated, with proper patient selection. Considering the treatment alternatives, revising a failed OCA transplantation can be a useful treatment option, especially for young and active patients who wish to avoid arthrodesis or arthroplasty. Level of Evidence: Level IV, case series.

To investigate the efficacy of intravitreal ranibizumab (IVR) combined with laser photocoagulation for aggressive posterior retinopathy of prematurity (AP-ROP) patients with vitreous hemorrhage, we conducted a retrospective observational case series study. A total of 37 eyes of 20 patients’ medical records were reviewed. Patients first received IVR (0.25 mg/0.025 mL) and later photocoagulation. The mean postconceptual age of injection was 34.6 ± 1.4 weeks, and the mean follow-up period was 39.3 ± 8.3 weeks. During the follow-up, 96.6% eyes had various degree of rapid absorption of vitreous hemorrhage after IVR. The mean time of received first photocoagulation after IVR was 4.8 ± 2.9 weeks. Ten (27.0%) eyes received second laser therapy and the mean time of second laser therapy after IVR was 3.2 ± 0.8 weeks. All eyes exhibited adequate regression of ROP and were stable with attached retina. Fibrosis membrane was observed in seven eyes (18.9%) and three of them demonstrated mild ectopic macula. No significant side effects related to IVR were observed. So IVR could be conducted as primary treatment of AP-ROP associated with vitreous hemorrhage, which can improve the fundus visibility, followed by conventional photocoagulation. Further randomized controlled trials are necessary to compare the clinical efficacy and safety with conventional interventions.

Objectives: To describe short-term efficacy of goniotomy with trabecular meshwork excision using the Kahook Dual Blade (KDB, New World Medical Inc., Rancho Cucamonga, CA) in patients with Primary Open Angle Glaucoma, (POAG) either as a standalone or plus Phacoemulsification (phaco). Method and Patients: A retrospective review of 12 eyes of 9 patients who had goniotomy with Kahook dual blade either as a standalone or combined with cataract surgery by phacoemulsification from April 2017 to July 2018 at Eye Foundation Hospital, Ikeja, Lagos. The patients were follow-up for a minimum of 6 months. Results: The mean age of the patients was 66.4±8.8 years. Mean preoperative intraocular pressure (IOP) for all eyes was 18.58±5.42mmHg. From day 1 through the 6th Month of postoperative follow-up, the mean IOP ranged from 18.58±9.26mmHg to 12.27±1.68mmHg representing reductions of 0-6.31mmHg (0-34%; p<0.05 at each time point versus baseline except for day 1). For the Phaco+KDB group, the baseline mean IOP was 19.25±4.56mmHg while the mean IOP postoperatively from day 1 to 6 months ranged from 19.13±8.99mmHg to 12.13±1.89mmHg representing reductions of 0.12mmHg to 5.13mmHg (0.6-30.2%; p<0.05 only from 1 month to 6 months). At baseline, the mean IOP for the eyes that had KDB goniotomy as a standalone was 17.25±7.45mmHg and postoperatively ranged from 17.50±11.09mmHg to 12.67±1.67mmHg representing reductions of -0.25-9.08mmHg (-1.45%-41.7%; p<0.05 at one week, 3 and 6 months only versus baseline). Conclusion: KDB either as a standalone or with phaco recorded at least 30% reduction in IOP after 6 months of followup in these series.

ABSTRACT: The purpose of this study was to describe our initial experience with double pelvic osteotomy (DPO) in young dogs affected by hip dysplasia (HD) and to report their postoperative outcome. Seven dogs (four females and three males) were included in our study with mean age 8.3 (±1.7) months, and mean body weight 29.5 (±7.4)Kg. Breeds involved were: Rottweiler (n = 1), Labrador Retriever (n = 3), Golden Retriever (n = 1), Great Dane (n=1) and São Miguel Cattle Dog (n = 1). The most common history complaints were: pelvic limb lameness and pain at hip extension and hip abduction. All surgical procedures consisted of osteotomy of the ilium and pubis, acetabular ventroversion and iliac stabilization with a customized bone plate with seven screws, four screws placed at the cranial fragment and the remaining three in the caudal aspect. Average surgical time was 65.8 (±10.4) minutes and median follow-up assessment was 68 (±15) days. Fracture healing was observed within mean period of 26.3 (±8.9) days. Six patients (86%) had satisfactory outcome and one patient didn’t improve after surgery and had to undergo a total hip replacement. Our results showed that DPO is an effective treatment for HD due to the preservation of pelvic geometry and low postoperative morbidity. Since it is a recent technique, further studies are recommended.

Background: This study investigated the clinical efficacy of combined posteromedial and posterolateral approaches for repair of 2-part posterior malleolar fractures associated with medial and lateral malleolar fractures. Methods: This case series report included 27 Weber B with Haraguchi type II patients with medial and lateral malleolar fractures combined with 2-part posterior malleolar fractures. Patients were treated with open reduction and internal fixation through a combination of posteromedial and posterolateral approaches from January 2015 to January 2018. There were 11 males and 16 females, with an average age of 61.5 years (range, 53-67 years). The procedures were performed on prone patients under spinal anesthesia. The medial, lateral, and posterior malleolar fractures were exposed through posteromedial and posterolateral approaches performed at the same time. The lateral malleolar fracture was fixed using a plate, the medial malleolar fracture was fixed using screws, and the posterior malleolar fracture was fixed using a plate or cannulated screws according to the size of the fragments. We performed follow-up on 22 patients for an average of 30 months (range, 18-48 months). Results: Primary healing of the incisions was achieved in all cases, and no infection was found. The mean time of bone union was 12.5 weeks (range, 10-15 weeks). The mean time from the operation to full weightbearing was 13 weeks (range, 11-16 weeks). We used the American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot Scale to score patient outcomes; the mean score was 85.4 (range, 80-92) at the final follow-up. No significant pain was found at the final follow-up. Conclusion: This study showed that satisfactory outcomes were achieved with combined posteromedial and posterolateral approaches. Therefore, we believe this approach was a good alternative strategy to repair 2-part posterior malleolar fractures associated with medial and lateral malleolar fractures. Level of Evidence: Level IV, retrospective case series.

Introduction: This prospective case series study aimed to assess the value of the Less Invasive Stabilization System (LISS) to treat closed Segmental Tibial Fractures (STFs) using a proposed surgical technique.Materials and methods: Between August 2010 and January 2014, 21 consecutive recently (within 1 week) closed STFs that matched the inclusion criteria were enrolled. Patients were treated with the 13-hole LISS plate. All patients were followed up every 2 weeks for the first 2 months, then every month for the rest of the first 6 months and then every 6 months thereafter. Patients were assessed radiologically during the follow-up appointments and clinically at the final visit by the Lower Extremity Functional Scale (LEFS) to evaluate the result.Results: The mean time to union of the proximal fracture was 15.72 ± 2.78 (range: 12–20) weeks and for the distal fracture was 20 ± 2.22 (range: 16–24) weeks, excluding delayed union in three patients. All patients except the three showed radiological observable callus in a mean duration of 4.95 (range: 3–7) weeks. The mean final follow-up LEFS was 72.4 (range: 60–80).Conclusion: The mean time to union of the proximal fracture was shorter than the distal fracture. The use of LISS to treat closed STFs using the proposed surgical technique has proved to give favorable results. Further studies using the described technique are needed to justify the achieved results.Level of evidence: IV (Prospective case series).

Primary Total Hip Arthroplasty

Introduction: Late chronic periprosthetic infections (LCPIs) are worrisome complications of primary hip arthroplasties. The gold standard procedure is the 2-stage revision. 1-stage exchange is gaining popularity in order to reduce the invasivity of the former technique. A partial 2-stage exchange technique, retaining fixed components, may overcome some of the drawbacks of the previous techniques, allowing a much easier reconstruction step. Methods: 28 patients with a LCPI after a primary total hip arthroplasty underwent a first removal stage: the loosened component was removed (23 cups and 5 stems) and the fixed component, with no local signs of infection, was retained. An antibiotic hand molded spacer was positioned in 16 cases. After a mean time of 8 months and a tailored antimicrobial therapy, the spacer was removed and the implant was revised. Results: The mean follow-up was 5 years. The HHS score was 82.7. 4 cases failed (2 patients presenting a septic relapse after revision and 2 patients undergoing Girdlestone arthroplasty), achieving a survival rate of 83.4% at 5 years. 2 patients were unwilling to perform a further procedure and did not proceed to the second stage. All the other patients had no clinical, radiological, laboratory signs of septic relapse. Conclusions: The partial 2-stage approach seems a promising technique for LCPI in selected cases, with good infection control. It allows an easier revision by sparing the fixed components. Larger case series and longer follow-ups are needed to confirm the results and identify the limits of this approach.

SummaryA retrospective case series study was done to determine the long-term outcome of operations upon dogs treated for canine hip dysplasia by means of a triple pelvic osteotomy (TPO). Twentyfour dogs with bilateral hip dysplasia, that received a unilateral TPO between January 1988 and June 1995, were re-examined at the Ontario Veterinary College. The assessment included physical, orthopedic and lameness examinations, standard blood work, pelvic radiographs and force plate gait analysis. They were compared to bilaterally dysplastic dogs that had not been treated, and also to normal dogs. Force plate data analysis demonstrated a significant increase in peak vertical force (PVF) and mean vertical force over stance (MVF) in the limb that underwent surgical correction by means of a TPO, when compared to the unoperated hip. It was determined that performing a unilateral TPO on a young dysplastic dog resulted in greater forces and weight bearing being projected through the TPO corrected limb when compared to the unoperated limb.Dogs with bilateral hip dysplasia treated with a unilateral triple pelvic osteotomy (TPO) were assessed by force plate gait analysis, radiographs and orthopedic examination. There was a significant increase in hip Norberg angles over time, although degenerative changes did progress. Limbs that had been operated upon had significantly greater peak and mean ground reaction forces than limbs that had not received an operation.
