Background: Periprosthetic hip infections (PHIs) are troublesome complications of hip arthroplasties. The gold standard procedure for treating chronic PHI is a 2-stage approach. Recently, however, more conservative approaches have been developed to spare the osseointegrated components and avoid sequestra, bone loss, devascularization, and difficult reconstructions. The partial two-stage approach, which leaves the well-fixed component in situ and removes the loosened component, may be an effective strategy. Objective: This paper, a narrative mini-review, analyzed the preliminary results of a partial 2-stage approach to treating chronic hip arthroplasty infections. Methods: Pertinent papers describing the partial 2-stage approach (leaving the well-fixed component in situ and removing the loosened component) were collected and evaluated. Results: Six main case series were selected. A total of 76 patients were included. Many patients were treated with socket removal and stem retention with quite similar surgical techniques. Many cases included highly virulent bacteria, and no pre-operative selection about comorbidities was performed. The first outcomes of this approach were promising, with a rate of infection control ranging from 81.3% to 100% at mid-term follow-up. Conclusion: This approach proved good at mid-term follow-up; however, many concerns still exist. In particular, the indications are imprecise, and the role of biofilm is still unclear. Despite the first good outcomes, the partial 2-stage approach for chronic PHI should be validated by multicenter prospective studies.

Aims In elderly patients with osteoarthritis and protrusio who require arthroplasty, dislocation of the hip is difficult due to migration of the femoral head. Traditionally, neck osteotomy is performed in situ, so this is not always achieved. Therefore, the purpose of this study is to describe a partial resection of the posterior wall in severe protrusio. Methods This is a descriptive observational study, which describes the surgical technique of the partial resection of the posterior wall during hip arthroplasty in patients with severe acetabular protrusio operated on between January 2007 and February 2017. Results In all, 49 hip arthroplasties were performed. The average age of patients was 60 years, and idiopathic was the most frequent aetiology of protrusio. All patients were treated with femoral head autograft and no intra- or postoperative complications were reported. No patients required revision surgery. Conclusion Partial resection of the posterior wall demonstrated to be a safe surgical technique with 100% survival in a follow-up to ten years in total hip arthroplasty due to severe acetabular protrusio.

Abstract BACKGROUND Various surgical techniques have been attempted to treat patients with failed anterior subcutaneous transposition performed for cubital tunnel syndrome. OBJECTIVE To analyze intraoperative findings of failed anterior subcutaneous transposition and to report the outcome of in Situ neurolysis of ulnar nerve. METHODS Patients who, under diagnosis of failed anterior subcutaneous transposition of ulnar nerve, underwent in Situ neurolysis between 2001 and 2018 were included in this study. We excluded patients with follow-up of less than one year, records of traumatic ulnar nerve injury, and concomitant double crush syndrome such as cervical spondylosis causing radicular pain, ulnar tunnel syndrome, or thoracic outlet syndrome. Surgical outcomes were evaluated using visual analog scale (VAS) pain score and Disabilities of the Arm, Shoulder, and Hand (DASH) score, which were assessed before and after surgery. A total of 28 elbows in 27 patients whose average age was 58.5 (range, 31-76) yr were enrolled, and the duration of follow-up was 5.8 (range, 1.0-14.9) yr. RESULTS The most common pathologic finding identified during operation was severe adhesion of the transposed nerve in all elbows, followed by incomplete decompression of deep flexor-pronator aponeurosis in 26 elbows (93%). The average VAS pain score improved from 4.9 (range, 2-7) to 1.3 (range, 0-5), and the average DASH score from 31.7 (range, 18.1-66.7) to 14.1 (range, 5.0-46.6). Of the 28 elbows, 27 (96.4%) showed improvement of preoperative symptoms. CONCLUSION In Situ neurolysis of ulnar nerve for patients with failed anterior subcutaneous transposition resulted in satisfactory outcome.

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.

Hip Arthroplasties

Aims Short-stemmed femoral implants have been used for total hip arthroplasty (THA) in young and active patients to conserve bone, provide physiological loading, and reduce the incidence of thigh pain. Only short- to mid-term results have been presented and there have been concerns regarding component malalignment, incorrect sizing, and subsidence. This systematic review reports clinical and radiological outcomes, complications, revision rates, and implant survival in THA using short-stemmed femoral components. Materials and Methods A literature review was performed using the EMBASE, Medline, and Cochrane databases. Strict inclusion and exclusion criteria were used to identify studies reporting clinical and radiological follow-up for short-stemmed hip arthroplasties. Results A total of 28 studies were eligible for inclusion. This included 5322 hips in 4657 patients with a mean age of 59 years (13 to 94). The mean follow-up was 6.1 years (0.5 to 20). The mean Harris Hip Score improved from 46 (0 to 100) to 92 (39 to 100). The mean Oxford Hip Score improved from 25 (2 to 42.5) to 35 (12.4 to 48). The mean Western Ontario & McMaster Universities Osteoarthritis Index improved from 54 (2 to 95) to 22 (0 to 98). Components were aligned in a neutral coronal alignment in up to 90.9% of cases. A total of 15 studies reported component survivorship, which was 98.6% (92% to 100%) at a mean follow-up of 12.1 years. Conclusion Short-stemmed femoral implants show similar improvement in clinical and radiological outcomes compared with conventional length implants. Only mid-term survivorship, however, is known. An abundance of short components have been developed and used commercially without staged clinical trials. Long-term survival is still unknown for many of these components. There remains tension between innovation and the moral duty to ensure that the introduction of new implants is controlled until safety and patient benefit are demonstrated. Implant innovation and subsequent use should be driven by proven clinical outcomes, rather than market and financial forces, and ethical practice must be ensured.

Superior Approach

This study aims to establish the midterm safety and performance for the direct superior approach to minimally invasive surgery total hip arthroplasty (MIS-THA). We used a unicentric, single-surgeon, retrospective, consecutive case series analysis of the first 40 patients who received primary unilateral direct superior MIS-THA. Special attention was given to functional recovery by measuring Harris Hip Score (HHS) and timed-up-and-go (TUG) with a mean follow up of 2.2 ± 0.4 years. A radiologic evaluation was performed. HHS and TUG improved significantly at three months and one year (p < 0.001). All components were placed within the Lewinnek safe zone with no change position or signs of loosening at two years. With a minimum of two years of follow up, the direct superior approach appears to be safe without any obvious or consistent postoperative complications—clinically or radiographically—with excellent functional recovery. Additionally, our subgroup analysis supported no late learning curve effect.

Fixation Techniques

The valgus-impacted (VI) 4-part fractures are a subset of fractures of the proximal humerus with a unique anatomic configuration characterized by a relatively lower incidence of avascular necrosis after operative intervention. We systematically reviewed clinical studies assessing the benefits and harms of least possible fixation techniques (LPFT) for this unique fracture type. Such information would be potentially helpful in developing an evidence-based approach in the management of these complex injuries. We performed analytic searches of PubMed, Embase, Web of Science, Google Scholar and the Cochrane Library, restricting it to the years 1991-2014. Included studies had to describe outcomes and complications after primary osteosynthesis with any type of LPFT apart from plate-screws and intramedullary nailing. Eligibility criteria were also included English language, more than 5 cases, minimum follow up of one year and report of clinical outcome using at least one relevant score (Constant, Neer or ASES). Based on 292 database hits we identified 12 eligible studies including 190 four-part valgus impacted fractures in 188 patients. All eligible studies were case series composed of min 8 to max 45 patients per study. The gender distribution was 60% (112) female and 40% (76) male. The average age of the patients at the time of injury was 54.5 years. In 8/12 studies an open reduction was used for fracture fixation using different surgical techniques including KW, cerclage wires, cannulated screws and osteosutures. Closed reduction and percutaneous fixation was used in 4 studies. Mean follow-up time ranged from 24 to 69 months. A good functional outcome (constant score &gt;80) was reported in 9/12 studies. The most common complication was avascular necrosis of the humeral head with an overall incidence of 11% (range, 0-26.3%). Total avascular necrosis (AVN) was found in 15/188 patients (7.9%) and was more common in percutaneous techniques and partial AVN in 6/188 (3.1%) being more common in open techniques. The overall re-operation rate was very low (3.7%). Insufficient study designs cannot provide definite treatment recommendations and quantitative data synthesis of outcome. In general, LPFT for 4-part VI fractures leads to satisfactory outcomes with low incidence of complications. A considerable risk of biases can be attributed to fracture classification, proper radiological control, mean age of patients, mixed types of fixation methods, nonage adjusted clinical scoring and small follow up periods. These factors are discussed in detail. Level of evidence: systematic review of literature (level IV) as most of the studies were level IV.

INTRODUCTION: Penoscrotal webbing (PSW) is an anomaly of penis and it includes penile and scrotal skin aberration. There are various surgical techniques for repairing PSW with different terminologies. Herein we present our surgical experience of Z-plasty procedure in these cases. METHODS: In this retrospective study, 5 patients with an average age of 46 months who were diagnosed and under follow-up for PSW, between June 2017 and May 2019 were included. Along with demographic and clinical characteristics, treatment and follow-up records were collected. RESULTS: Isolated PSW was observed in 4 patients and one patient had an associated megameatus intact prepuce (MMIP) of a hypospadias variant in addition to PSW. Circumcision and ventral prepuce reconstruction of the penis with the aid of "Z-plasty" solved problem and acceptable postoperative results were obtained. DISCUSSION AND CONCLUSION: PSW is a condition that warrants surgical treatment. During the management of these children, in the case of suspicion of penile skin abnormality at the time of circumcision, it should be deferred and should be consulted to a pediatric surgeon or a pediatric urologist. Gentle surgical treatment is recommended for a favourable surgical and psychological result

Published Evidence

Introduction: Longevity and success of total hip arthroplasty (THA) is largely dependent on component positioning. While use of robotic platforms can improve this positioning, published evidence on its clinical benefits is limited. Therefore, the aim of this study was to assess the clinical outcomes of THA with robotic surgical assistance. Materials and Methods: We conducted an analysis of robotic arm-assisted primary THAs performed by a single surgeon utilizing a posterior approach. A total of 99 patients (107 cases) who had a minimum two-year follow up were identified. Their mean age was 61 years (range, 33 to 84 years), and their mean body mass index was 30.5 kg/m2 (range, 18.5 to 49.1 kg/m2). There were 56% female patients and primary osteoarthritis was the principal hip diagnosis in 88.8%. Operative times, lengths of hospital stay, and discharge dispositions were recorded, along with any complications. Modified Harris Hip Scores (HHS) were calculated to quantify clinical outcomes. Results: Mean postoperative increases in HHS at 2- to 5.7-year follow up was 33 points (range, 6 to 77 points). There were no complications attributable to the use of robotic assistance. Surgical-site complications were rare; one case underwent a revision for prosthetic joint infection (0.93%) but there were no dislocations, periprosthetic fractures, or cases of mechanical implant loosening. There was no evidence of progressive radiolucencies or radiographic failure. Discussion: Robotic arm-assisted THA resulted in low complication rates at minimum two-year follow up, with clinical outcomes comparable to those reported with manual surgery.1–4 The haptically-guided acetabular bone preparation enabled reliable cementless acetabular fixation and there were no adverse events related to the use of the robot. Dislocations were avoided in this case series. Randomized controlled clinical trials are needed to compare manual to robotic surgery and to investigate whether the precision found with this functional planning will reliably reduce the incidence of dislocations.
