Percutaneous elevation of radial head fractures without fixation - a promising technique.

The aim of the study is to describe the surgical technique and to report the outcomes of triceps reflecting anconeus pedicle (TRAP) approach for intercondylar fractures of the humerus. Twenty two patients with intercondylar fractures of the humerus were operated on by open reduction via the TRAP approach and internal fixation with dual precontoured locking plates. Data were collected on union time, postoperative complications, range of motion (ROM), triceps power, and objective clinical measurement. All fractures were united with a mean union time of 16.5 weeks (range 12-22). All patients had good-to-excellent Mayo Elbow Performance (MEP) score results with a mean ROM of 118.2 degrees (range 90-135). Triceps power was grade 5 in 16 patients and grade 4 in 6. There were 3 transient ulnar nerve palsy and 1 heterotopic ossification. TRAP approach is safe and effective in terms of utility for articular reduction, restoration of elbow motion, and triceps function for intercondylar fractures of the humerus.

Total hip arthroplasty in acute acetabulum fractures: a systematic review.

INTRODUCTION: The incidence of acetabular fractures has increased significantly in recent years due to demographic change. It can be divided into high-energy acetabular fractures primarily seen in adult patients versus geriatric patients mostly suffering from low-energy trauma. Historically, acetabular fractures have been treated either non-operatively or surgically following open reduction and internal fixation (ORIF), whereas nowadays total hip arthroplasty (THA) provides a true alternative. Aim of this study was to perform a systematic review on the outcome following THA in acute acetabulum fractures. METHODS: PubMed/MEDLINE, Cochrane and Google databases were systematically searched on December 9, 2021. The key terms were [acetabular fracture] AND [[arthroplasty] OR [fixation]]. All retrospective and prospective original studies in English and German were analyzed the outcome following THA in acute acetabulum fractures were included. RESULTS: A total of 2459 studies were screened, which includes 15 studies that met the inclusion criteria with a total of 590 patients at a mean age of 61.3 years (SD 11.48). Most studies described good to excellent results. Especially, THA allows elderly patients quicker mobilization and rehabilitation as well as symptomatic relief, as compared to ORIF or non-operative treatment. Patients who underwent non-operative treatment showed better results compared to those who underwent ORIF initially. CONCLUSION: In acetabulum fractures, THA provides a good alternative with very good results when patients are carefully selected. Good to excellent outcomes are reported for both acute and delayed use of THA in elderly patients. LEVEL OF EVIDENCE: Level 2, systematic review.

Surgeon-Placed Erector Spinae Plane Catheters for Multilevel Lumbar Spine Fusion: Technique and Outcomes Compared With Single-Shot Blocks.

BACKGROUND: Postoperative pain management of multilevel lumbar fusion remains challenging. There are few reports of opioid-sparing regional analgesia for spine surgery. We present a novel method for surgeon-placed erector spinae plane (ESP) catheters for multilevel lumbar spine fusion and compare pain- and opioid-related outcomes in a matched cohort who received anesthesiologist-placed ESP blocks. METHODS: A retrospective matched pilot study of 18 patients: 6 received intraoperative, bilateral ESP catheters. Tunneled catheters were placed under the intact ESP at the proximal end of the incision. Continuous infusions of ropivacaine (0.2%) were started in the postanesthesia care unit (PACU) after emergence from anesthesia and maintained for 48 hours. Catheter patients were matched 1:2 with 12 patients who received preincision single-shot ESP blocks administered by an anesthesiologist, according to age, gender, American Society of Anesthesiologists class, body mass index, and number of spinal levels fused. All patients were provided opioid intravenous patient-controlled analgesia (IV-PCA). Numeric rating scale pain scores (NRS, 0-10), length of stay (LOS), opioid consumption (oral morphine equivalents, mg), opioid side effects, and complications (motor weakness, local anesthetic toxicity, infection, technical issues, and failure), were compared in the PACU and on the nursing floor. RESULTS: Only 1/6 patients with ESP catheter used opioid IV-PCA, compared with 11/12 who received ESP blocks. There were no differences in total opioid consumption (catheters: 135 ± 141 mg; blocks: 183 ± 112 mg; P = 0.448) or median (interquartile range) LOS (catheters: 73 [50,107] hours; blocks: 90 [72,116] hours, P = 0.708). NRS pain was significantly higher in the PACU after ESP catheters (5.9 ± 1.7) vs ESP blocks (3.3 ± 2.4; P = 0.036), but no differences were found at later timepoints (5.0 ± 1.6 vs 4.3 ± 1.1, respectively; P = 0.383). No catheter-related complications were found. CONCLUSION: Surgeon-placed ESP catheters represent a simple technique to provide regional analgesia, particularly in centers lacking regional anesthesiology services. Risks, benefits, and efficacy compared to other techniques require prospective study.

The cervical spine demonstrates less postoperative bone loss than the lumbar spine.

The objective of this study is to determine the bone mineral density (BMD) changes in adjacent vertebra following anterior cervical discectomy and fusion (ACDF). Consecutive patients undergoing ACDF with available preoperative and postoperative computed tomography (CT) imaging were included. Quantitative CT measurements of screw-free cervical and first thoracic vertebra were performed. Comparisons between pre- and postoperative BMD in the vertebrae one or two levels above the upper instrumented vertebra (UIV + 1, UIV + 2) and one level below the lowest instrumented vertebra (LIV + 1) were assessed. Seventy-two patients (men, 66.7%) met the inclusion criteria. The patient population was 91.7% Caucasian with a mean age of 55.0 years. The mean interval (±SD) between surgery and secondary CT was 157 ± 23 days. Preoperative BMD (±SD) in UIV + 1 was 300.6 ± 66.2 mg/cm3 . There was a significant BMD loss of 1.5% at UIV + 1 after surgery, resulting in a postoperative BMD of 296.2 ± 64.8 mg/cm3 (p = .029). At UIV + 2 and LIV + 1, no significant differences between pre- and postoperative BMD (304.7 ± 75.7 mg/cm3 vs. 299.8 ± 74.3 mg/cm3 , 197.3 ± 50.4 mg/cm3 vs. 200.8 ± 48.7 mg/cm3 , p = .113 and p = .078, respectively) were observed. Clinical significance Our results demonstrate a small BMD decrease of 1.5% at UIV + 1. This suggests that the effect of ACDF surgery on the adjacent levels might be smaller compared to the previously described lumbar BMD loss of 10%-20% following posterior lumbar fusion procedures.
