A Comparison of Outcomes in Acute Perilunate Injuries: Systematic Review and Meta-Analysis of Treatment Approaches.

BACKGROUND: Perilunate dislocations (PLD) and fracture-dislocations (PLFD) comprise a spectrum of high-energy wrist injuries. The purpose of this review was to review operative strategies for perilunate injuries based on approach and compare outcomes. METHODS: A systematic review of literature on PLD and fracture-dislocations was carried out according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). PubMed and EMBASE databases were queried for literature. Inclusion criteria included English studies reporting clinical or functional outcomes of acute PLD and PLFD. RESULTS: Twenty-nine full-text articles (604 PLD and PLFD injuries) were included. The most common method of PLD and PLFD fixation is through an open approach with combined volar and dorsal exposure. There were no differences between approaches with regard to total arc range of motion, grip strength, Mayo Wrist Score, or mean scapholunate angle. Similarly, there was no difference between approaches and postoperative radiographic arthritis or complications. Most patients were able to return to their prior level of function and work. The incidence of postoperative complications ranged from 0% to 22.5%. CONCLUSION: Current evidence shows no difference in postoperative total wrist arc range of motion, grip strength (as compared to contralateral), or Mayo Wrist Score with regard to surgical approach. The most common method of PLD and PLFD fixation in the literature is through an open approach with combined volar and dorsal exposure. There is a large difference in reported rates of radiographic arthritis, although this finding does not appear to correlate with postoperative pain or disability. LEVEL OF EVIDENCE: I, Systematic Review.

Osteolysis Following the Use of Polyetheretherketone Suture Anchors in Hand and Wrist Surgery: A Preliminary Study.

PURPOSE: The objective of this study was to investigate and describe the presence of osteolysis after implantation of polyetheretherketone (PEEK) suture anchors in the hand and wrist. METHODS: Patients who underwent hand or wrist surgery using PEEK suture anchor(s) at a large academic institution from January 2019 to January 2021 were identified. Patients without accessible intraoperative fluoroscopic imaging were excluded. Patient demographics, type of procedure, and suture anchor material were recorded. The suture anchor tunnel size was measured on sequential radiographs and recorded as percentage change. Descriptive statistics were used to summarize findings. RESULTS: A total of 26 PEEK suture anchors in 14 patients were included, with an average follow-up of 12.0 months (range, 1.5-24.1 months). Twenty-seven percent of the anchors (7/26) demonstrated osteolysis at final follow-up, as defined by enlargement of tunnel size by >30%. In all anchors, the tunnel size increased by 19.1% on average (range, -7.7% to 56.1%) by final follow-up. CONCLUSIONS: Polyetheretherketone suture anchors may be associated with the development of osteolysis in hand and wrist surgery. The clinical implications of osteolysis in the smaller bones of the hand and wrist remain unclear. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

The Cam-Post Dislocation in Posterior-Stabilized Total Knee Arthroplasty A Case Series.

Cam-post dislocations are a unique complication of total knee arthroplasty (TKA) designs that utilize a cam-post mechanism, representing an extreme form of deep flexion instability. They are rare complications and are poorly defined in the existing literature. The purpose of this case study is to present a series of six cam-post dislocation cases to improve understanding of this complication and its mechanism, presentation, and available treatment options. All patients experienced cam-post dislocations after a deep flexion moment that were identified clinically and confirmed radiographically. Affected implants included both primary and revision components and all utilized a cam-post mecha- nism. Three patients underwent revision surgery whereas the remaining three were treated with closed reduction only. Cam-post dislocations are rare complications of posterior- stabilized TKA that should be understood and recognized by adult reconstruction surgeons. Closed reduction may be achieved with hyperflexion and anterior drawer or with hyperextension, but these patients may ultimately require a revision procedure.

Acute Hantavirus Infection Presenting With Fever and Altered Mentation in the Absence of Pulmonary or Renal Manifestations.

Illness caused by hantaviruses is often severe and is typically characterized by diffuse pulmonary disease or renal insufficiency depending on the type of hantavirus. Here we report 2 cases of hantavirus infection that resulted in severe cognitive impairment but did not have any pulmonary or renal manifestations. These 2 cases may be indicative of previously underreported symptoms of hantavirus infection and might represent examples of hantavirus-related encephalopathy.

Anterior Talofibular Ligament Augmentation With Internal Brace in the Office Setting.

The anterior talofibular ligament (ATFL) is the most frequently injured lateral ligament of the ankle, and up to 20% of patients with ankle sprains may require surgical intervention to correct chronic lateral ankle instability. There has been increased interest in arthroscopic lateral ankle ligament repair techniques to minimize postoperative pain and expedite recovery. Additionally, the use of suture-tape augmentation may allow for improved recovery in those with ATFL reconstruction. The goal of this Technical Note is to describe the steps to performing in-office needle arthroscopy using suture tape as an internal brace for an ATFL deficient ankle. We also include an accompanying discussion on indications and opportunities afforded by an in-office procedure over the traditional operating room suite.

Endoscopic Carpal Tunnel Release: Techniques, Controversies, and Comparison to Open Techniques.

Endoscopic carpal tunnel release (ECTR) continues to rise in popularity as a treatment option for carpal tunnel syndrome. Numerous variations in technique and instrumentation currently exist, broadly classified into two-portal and single-portal techniques with antegrade and retrograde designs. ECTR is equally effective as open carpal tunnel release for alleviating symptoms of carpal tunnel syndrome with no differences in long-term outcomes. ECTR has an increased risk of transient nerve injury, whereas open carpal tunnel release has an increased risk of wound and scar complications. ECTR has higher direct costs but is associated with earlier return to work. ECTR is a safe and effective approach to carpal tunnel release in the hands of experienced surgeons.

Posterior Hindfoot Needle Endoscopy in the Office Setting.

Posterior hindfoot disorders encompass a spectrum of bony, cartilaginous, and soft-tissue pathology. Traditional open surgical techniques have been increasingly replaced by less-invasive arthroscopic and endoscopic approaches. Recent innovations such as the advent of the needle arthroscope continue to push the boundary of minimally invasive interventions. This Technical Note highlights our technique for posterior hindfoot needle endoscopy for common posterior hindfoot pathologies in the wide-awake office setting, including indications, advantages, and technical pearls.

Achilles Paratenon Needle Tendoscopy in the Office Setting.

Achilles tendinopathy is a common inflammatory condition of the Achilles tendon prevalent in the athletic population in which patients present with pain, swelling, and reduced performance exacerbated by physical activity. Operative intervention using either open or percutaneous approaches has traditionally been performed after failure of nonoperative treatment, but less invasive modalities that include endoscopic approaches have been increasingly used. This Technical Note highlights our technique for Achilles paratenon needle tendoscopy in the wide-awake office setting, with accompanying indications for use, advantages, and technical pearls.

In-Office Needle Arthroscopy for Anterior Ankle Impingement.

Anterior ankle impingement is a common cause of chronic ankle pain characterized by altered joint mechanics with considerable deficits in range of motion. The benefits of in-office nano arthroscopy (IONA) include the ability to diagnosis and treat anterior ankle impingement, quicker patient recovery, reduced cost, and improved patient satisfaction. The purpose of this technical report is to describe the technique for performing in-office nano arthroscopy for anterior ankle impingement, with special consideration of the technique for obtaining adequate local anesthesia, proper indications, adequate visualization, and the advantages of performing these procedures in the office rather than the operating room.

In-Office Needle Tendoscopy of the Tibialis Posterior Tendon with Concomitant Intervention.

Tendoscopy has been recognized to be a useful technique in the diagnosis and treatment of early tibialis posterior tendon (TPT) dysfunction. Although open surgical procedures for advanced TPT disease have led to excellent outcomes, disagreement persists concerning the correct management algorithm for early TPT dysfunction. Recent developments in needle tendoscopy have provided a minimally invasive option for direct evaluation and intervention throughout the forefoot, midfoot, and hindfoot. The goal of this manuscript is to describe the technique for performing in-office needle tendoscopy targeting the TPT with a discussion of indications and opportunities afforded by an in-office procedure over the traditional operating room suite.

In-Office Needle Tendoscopy of the Peroneal Tendons.

In-office needle tendoscopy (IONT) can be used for the diagnosis and treatment of several peroneal tendon pathologies including peroneal tendon tendinopathy, tears, and instability. Benefits of IONT for peroneal tendon disorders include the ability to dynamically evaluate peroneal tendon stability, quicker patient recovery, reduced cost, and improved patient satisfaction. Several studies have suggested that tendoscopic treatment may avoid several complications related to open treatment of peroneal tendon pathologies, including scar formation and groove stenosis. The purpose of the present report is to describe the technique for performing IONT for common peroneal tendon pathologies. This Technical Note describes the techniques for obtaining adequate anesthesia and performing IONT, indications, and advantages of performing these procedures in the office rather than in the operating room.

Needle Arthroscopy Cheilectomy for Hallux Rigidus in the Office Setting.

Hallux rigidus is a progressive degenerative process of the first metatarsophalangeal joint characterized by altered joint mechanics and formation of dorsal osteophytes. Cheilectomy is the preferred operative intervention at early stages. Technologic advances, patient preference, and cost considerations combine to stimulate the development of minimally invasive and in-office interventions. This Technical Note highlights our technique for needle arthroscopy cheilectomy for hallux rigidus, which can be used either in the operating room or in the wide-awake office setting.

Compartment Syndrome of the Foot.

Foot compartment syndrome is an uncommon condition that should be recognized by all orthopedic surgeons. The clinical presentation is often less clear than other limb compartment syndromes and requires high clinical suspicion with a low threshold for direct measurement of compartment pressure. Controversy exists regarding the number of anatomic compartments and the most effective treatment. Both acute surgical intervention and delayed management can result in significant morbidity and long-term sequelae.

Pediatric Facial Fractures: An Assessment of Airway Management.

Pediatric facial fractures present unique and challenging management considerations, especially with regards to airway management. Anatomical differences in children increase both airway resistance and the difficulty of intubation. A surgical airway may be required if intubation is unable to be performed. The purpose of this study was to examine a single center's experience with pediatric facial fractures to determine the frequency of advanced airway use, as well as the risk factors that may predispose a patient to requiring an advanced airway. A retrospective review of all facial fractures at a level 1 trauma center was performed from 2000 to 2012. Patients age 18 years and younger were included. Patient demographics were collected, as well as location of fractures, concomitant injuries, services consulted, and surgical management strategies. Information was collected regarding the need for an advanced airway, including intubation and the need for a surgical airway. A total of 285 patients met inclusion criteria. Of these, 57 patients (20%) required emergency intubation and 5 (1.8%) required a surgical airway. Intubation was significantly related to fractures of the midface, frontal sinuses, spine, skull, and pelvis, as well as depressed Glasgow coma scores and traumatic brain injury. The need for a surgical airway is extremely uncommon (1.8%), and tracheostomy was only needed in the setting of penetrating head trauma. Both emergent intubation and tracheostomy are associated with complications, but these complications must be weighed against the potentially life-saving measure of securing an airway.

Effect of Additional Sutures per Suture Anchor in Arthroscopic Bankart Repair: A Review of Single-loaded Versus Double-loaded Suture Anchors.

PURPOSE: To directly compare single-loaded suture anchors (SSA) with double-loaded suture anchors (DSA) to help surgeons optimize the operative technique, time, and cost of Bankart repairs. METHODS: A literature review was performed using the PubMed and SCOPUS databases. Studies that directly compared SSA and DSA for Bankart repairs, or indirectly compared them by collecting relevant data despite a different objective, were included. RESULTS: A total of two studies were included, both of which were cadaveric laboratory studies. A total of 28 shoulders were tested. Tests conducted include loading to failure and cyclic loading. One study found SSA to be biomechanically equivalent to DSA, and one found DSA to be superior. CONCLUSIONS: Based on limited cadaveric study, DSA are at least equivalent biomechanically to SSA, and may be superior. By using DSA, surgeons create repair constructs that are as strong as, or stronger than, those made with SSA, but with fewer anchors. This reduces the amount of holes drilled and implants placed in the glenoid, while also minimizing cost. CLINICAL RELEVANCE: Quantifying the benefit of additional sutures in a suture anchor can help optimize the quality of repair, time, and cost in arthroscopic shoulder repair.

Radiologic evaluation of postoperative gastropericardial fistula.

Laparoscopic Nissen fundoplication is the current standard surgical option for complicated GERD and symptomatic hiatal hernia. Though comparable in safety, short-term efficacy, and patient satisfaction when compared with open operation, laparoscopic Nissen fundoplication has demonstrated shorter hospital stays and recuperative times. Commonly reported complications include gastric or esophageal injury, splenic injury, pneumothorax, bleeding, pneumonia, fever, wound infections, and dysphagia. We present an unusual case of gastropericardial fistula that developed as a late complication of laparoscopic Nissen fundoplication performed 4 years earlier.
