Does the Nonunion Rate of Atypical Femoral Fractures Differ According to Fracture Site?: A Meta-Analysis.

Background: The nonunion rate for atypical femoral fractures (AFF) is known to be higher than that for typical fractures of the femur. We performed a meta-analysis to determine the incidence of nonunion necessitating reoperation following fixation for AFF and compare the rates according to the fracture site (subtrochanter or midshaft).

Methods: A total of 742 AFFs from 29 studies were included.

Open Reduction and Internal Fixation for Vancouver B1 and B2 Periprosthetic Femoral Fractures: A Proportional Meta-Analysis.

Purpose: Periprosthetic femoral fracture (PFF) is a common complication after total hip arthroplasty, and open reduction and internal fixation (ORIF) is a common surgical treatment. We conducted a meta-analysis to compare the outcomes of ORIF in patients with different fracture patterns (Vancouver B1 and B2).

Materials And Methods: We conducted a systematic search of PubMed, Embase, Cochrane Library and KoreaMed from inception to August 2022.

Regional versus General Anesthesia in Postoperative Pain Management after Distal Radius Fracture Surgery: Meta-Analysis of Randomized Controlled Trials.

Distal radius fractures are the most prevalent upper extremity fractures, posing a significant public health concern. Recent studies comparing regional and general anesthesia for postoperative pain management after these fractures have yielded conflicting results. This meta-analysis aimed to compare the effectiveness of regional and general anesthesia concerning postoperative pain management and opioid consumption following distal radius fracture surgery.

Medial patellofemoral ligament reconstruction appears to be a better treatment than repair, proximal realignment, or conservative management for primary patellar dislocation: A network meta-analysis.

Background: The purpose of this study was to compare the functional outcomes and re-dislocation rates of medial patellofemoral ligament (MPFL) reconstruction, MPFL repair, combined proximal realignment (CPR), and conservative management for primary patellar dislocation by conducting a systematic literature search of the available studies. The hypothesis was that MPFL repair and MPFL reconstruction would be better options for treating primary patellar dislocation.

Methods: Randomized controlled trials or prospective studies of primary patellar dislocation treated with MPFL reconstruction, MPFL repair, CPR, or conservative management were identified from the MEDLINE, EMBASE, and the Cochrane Library databases through December 31, 2021.

Anterior tibial displacement on preoperative stress radiography of ACL-injured knee depending on knee flexion angle.

Purpose: To compare side-to-side difference (SSD) of anterior tibial translation in instrumented stress radiography for each series of anterior cruciate ligament (ACL)-injured subjects according to knee flexion angle.

Methods: Forty subjects who were suspected of having significant ACL injury by manual Lachman test and MRI were recruited for this prospective study. These subjects took stress radiographs for both knees with corresponding knee flexion of 10° (series M1) and 30° (series M2) using Telos stress device.

Editorial Commentary: Outcomes of Arthroscopic Triangular Fibrocartilage Complex Repair: Can We Predict Who Will Benefit or Not?

The arthroscopic repair of avulsed triangular fibrocartilage complex generally demonstrates a satisfactory outcome after ruling out additional combined pathologies for ulnar-sided wrist pain. Previous studies have reported that 10% to 20% of patients complain of dissatisfaction with this surgical treatment, suggesting that it is not effective for all patients. Several prognostic factors for poor outcomes such as female gender, chronicity, baseline functional state, and reduced pronator quadratus muscle mass have been proposed.

Comparison of Ultrasound-Guided Versus Landmark-Based Corticosteroid Injection for Carpal Tunnel Syndrome: A Prospective Randomized Trial.

Purpose: Although a local corticosteroid injection for carpal tunnel syndrome (CTS) is frequently performed by palpation using anatomical landmarks, ultrasound (US) allows physicians to visualize and confirm placement of the injectate close to the median nerve, possibly improving the efficacy of the injection. The aim of this study was to compare the effectiveness and complications of US-guided steroid injections with landmark-based injections for CTS.

Methods: A total of 102 patients with CTS were randomized into 2 groups: landmark-based injection and US-guided injection.

Altered gene and protein expressions of vitamin D receptor in skeletal muscle in sarcopenic patients who sustained distal radius fractures.

Despite the presence of vitamin D receptor (VDR) in skeletal muscle cells, the relationship between VDR expressions and muscle mass or function has not been well studied. The purpose of this study was to compare VDR gene and protein expression in the forearm muscle between sarcopenic and non-sarcopenic individuals who have sustained distal radius fractures. Twenty samples of muscle tissue from sarcopenic patients (mean age 63.

Idiopathic Avascular Necrosis of Trapezoid in Adolescence: 3-Year Follow-Up.

Avascular necrosis (AVN) is relatively uncommon in the carpal bones, although it most frequently involves the lunate and scaphoid. The trapezoid has abundant vascular channels from a rich network of dorsal and palmar vessels, and only a few cases of AVN have been reported in adults who sustained a traumatic insult. We present a rare case of idiopathic AVN of the trapezoid in an adolescent presenting with refractory pain at the second metacarpal base.

Prognostic Factors for Nonsurgically Treated Sagittal Band Injuries of the Metacarpophalangeal Joint.

Purpose: The aim of this study was to evaluate the factors that influence the prognosis for patients with sagittal band injuries who were treated nonsurgically.

Methods: A total of 94 patients who had been diagnosed with traumatic sagittal band injury and initially treated with 7 weeks of metacarpophalangeal (MCP) joint extension orthosis wear (5 weeks of full-time followed by 2 weeks of part-time use) were studied. The response to treatment, including finger range of motion (ROM), extensor tendon instability, grip strength, and functional outcome measured as Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score were assessed at 24-week follow-up.

Prognostic effect of pain sensitization in patients with de Quervain's tenovaginosis receiving corticosteroid injection.

We investigated the influence of pain sensitization on the prognosis of de Quervain's tenovaginosis after a local corticosteroid injection. One hundred and fifteen patients with de Quervain's tenovaginosis who were treated with corticosteroid injection were recruited. We initially measured pain sensitization by assessing the patients' pressure pain thresholds in the mid-dorsal forearm and by administering a Pain Sensitivity Questionnaire.

Prognostic Value of Pain Sensitization During Early Recovery After Distal Radius Fracture in Complex Regional Pain Syndrome.

Objective: To evaluate the influence of pain sensitization in the early recovery of distal radius fractures (DRFs) on the occurrence and prognosis of complex regional pain syndrome (CRPS) type I.

Methods: We enrolled 58 patients who were diagnosed with CRPS I based on Budapest criteria within six months after sustaining DRF; they were age- and gender-matched with 58 patients with DRF who did not have CRPS I. We commonly measured patients' pressure pain thresholds (PPTs) in the forearm and administered a Pain Sensitivity Questionnaire (PSQ) when patients complained of pain with numeric rating scale ≥4 at three-month follow-up.

Comparison of clinical outcomes after ulnar shortening osteotomy for ulnar impaction syndrome with or without arthroscopic debridement.

Forty-four patients who had been diagnosed with ulnar impaction syndrome and who were scheduled to undergo ulnar shortening osteotomy were randomized into two groups, one treated by ulnar shortening osteotomy alone and the other treated by ulnar shortening osteotomy combined with arthroscopic debridement. The response to treatment, including the pain numeric rating scale in an ulnar provocation test and the Disability of the Arm, Shoulder and Hand score was assessed at 3 and 12 months after surgery. The mean pain and disability scores showed significant clinical improvement at the 12-month follow-up in both groups.

Prognostic Factors of Arthroscopic Debridement for Central Triangular Fibrocartilage Complex Tears in Adults Younger Than 45 Years: A Retrospective Case Series Analysis.

Purpose: The purpose of this study was to analyze factors that affect the treatment outcomes of arthroscopic debridement for central triangular fibrocartilage complex (TFCC) lesions in adults <45 years of age.

Methods: A total of 71 patients (mean age, 39 years; range, 20-44 years) who had been arthroscopically diagnosed with central TFCC tears were treated with arthroscopic debridement. Demographic, clinical, and arthroscopic findings were examined and analyzed.

Validity, Reliability and Responsiveness of the Korean Version of Quick Disabilities of the Arm, Shoulder, and Hand Questionnaire in Patients with Carpal Tunnel Syndrome.

Background: The Quick Disabilities of the Arm, Shoulder, and Hand questionnaire (QuickDASH) is one of the most widely used questionnaires for assessing functional ability of the patients with upper extremity diseases. Carpal tunnel syndrome (CTS) is the most common neuropathic disease in the upper extremities. The aim of this study was to verify the validity, reliability, and responsiveness of Korean version of QuickDASH questionnaire (K-QuickDASH) in the patients with CTS.

Clinical features affecting the patient-based outcome after minimal medial epicondylectomy for cubital tunnel syndrome.

Background: Little information is currently available to analyze unsatisfactory surgical outcomes for cubital tunnel syndrome (CuTS). The aim of this study was to analyze the clinical features influencing patient-reported outcomes of minimal medial epicondylectomy for CuTS.

Methods: We evaluated 91 patients who underwent minimal medial epicondylectomy for CuTS using the grip strength; two-point discrimination; Disability of the Arm, Shoulder and Hand (DASH) questionnaire; and a satisfaction with treatment questionnaire for one year, postoperatively.

Ultrasound-guided versus blind corticosteroid injections for De Quervain tendinopathy: a prospective randomized trial.

Unlabelled: A total of 154 patients with De Quervain tendinopathy were randomized into a blind injection group or an ultrasound-guided injection group to compare effectiveness and complications of steroid injection. The visual analogue scale score for pain, Finkelstein test result, and Disability of the Arm, Shoulder, and Hand (DASH) score were assessed at 12 and 24 weeks follow-up. At 12 weeks, the DASH scores were significantly better in the ultrasound-guided group, but the mean difference was less than the minimum clinically important difference.
