Objectives: The relationship between volar fragment size and postoperative volar tilt loss in complete articular distal radius fracture is not well known. In this study, we measured precise radiological parameters to help identify other factors that might contribute to volar tilt loss.

Material And Methods: We retrospectively reviewed the radiological examinations and charts of 256 patients with distal radial fracture who underwent volar locking plate fixation between March 2014 and July 2022.

The appropriate surgical management of osteochondral lesions of the talus (OLT) remains a challenge for foot and ankle surgeons. Currently, microfracture (MF) is the first-line operative treatment for small osteochondral lesions. However, the fibrous cartilage regenerated after MF is mechanically inferior to hyaline cartilage regeneration and is susceptible to deterioration over time.

Background: Surgical management of a massive rotator cuff tear (RCT) is always challenging. This study describes the clinical and radiological outcomes of patients who underwent bridging grafts using a plantaris tendon for an irreparable RCT.

Methods: Thirteen patients with a massive RCT were treated with arthroscopic interposition of a folded plantaris tendon autograft between June 2017 and January 2020.

Objectives: To compare radiological and clinical outcomes between lateral locking plate (LLP) and dual-plate fixation (LLP and additional medial buttress plate) for proximal humerus fractures with medial column comminution and varus deformity in patients with osteoporosis.

Design: Retrospective.

Setting: Academic medical center.

Background: Intratendious ganglions are rare lesions, especially on the foot and ankle. Although several studies have presented the intratendinous ganglion of the foot and ankle, there are only few reported cases, and no cases of recurrence or secondary surgery have been reported.

Case Summary: We present the case of a 32-year-old man with an intratendinous ganglion of the second extensor digitorum brevis (EDB) tendon that recurred after ganglion excision.

Previous studies have reported a prevalence of tarsal coalition of 0.03-13%. Calcaneonavicular coalition is known as main anatomical type, and the bilateral occurrence of tarsal coalition is known to be 50% or more.

Introduction: Plate osteosynthesis is preferred for the treatment of proximal humerus fractures (PHFs). However, applying the locking plate flush against the bone may lead to varus malreduction and medial displacement of the humeral head. We hypothesized that slight valgus reduction and valgus bent locking plate fixation against potential varus deformation would yield better results than the traditional plate fixation.

Background: Surgical approach is an important factor that may affect the outcomes of reverse total shoulder arthroplasty (RTSA). The most common approaches for RTSA are anterosuperior (AS) and deltopectoral (DP). However, controversy exists on which surgical approach is better.

Distal humeral fractures are challenging injuries seen in the elderly. Open reduction and internal fixation (ORIF) are the gold standard treatments. Total elbow arthroplasty (TEA) is an alternative to ORIF.

The ulnar coronoid process plays a key role in maintaining elbow stability; however, there is no gold standard treatment for ulnar coronoid process fractures. We present a novel surgical technique, arthroscopic reduction and bent K-wire fixation, for type II and III coronoid process fractures according to the O'Driscoll classification. Five patients were treated and retrospectively reviewed between January 2016 and December 2019.

Background: Low transcondylar fractures (LTFs) of the distal humerus are relatively uncommon elbow injuries in elderly patients after low-energy injuries. Although there is still debate regarding the method of fixation, several surgeons prefer bi-columnar fixation using pre-contoured locking plates. However, posterior approaches, which are usually used to perform the above procedure, have disadvantages, such as ulnar nerve neuropathy, damage to the extensor mechanism, and the need for general anesthesia.

Periprosthetic joint infection (PJI) after shoulder arthroplasty is a devastating complication that requires several additional surgeries. The purpose of this study was to assess the evidence regarding risk factors for PJI and identify those that contribute to infection by performing a meta-analysis. We searched the PubMed, Embase, and Cochrane Library databases for studies that assessed the risk factors for infection after shoulder arthroplasty.

We describe a technique for treating irreparable rotator cuff tears (RCTs) by bridging grafts with a long tendon autograft. In this technique, the plantaris tendon is harvested and prepared in a Y-shaped graft. The folded end of the graft is anchored to the greater tubercle and the other 2 limbs are fixed to rotator cuff tissue using modified Mason-Allen stitches.

Objective: Both transarticular screw fixation (TAS) and segmental screw-rod fixation (SF) have been widely performed for C1-2 fusion; however, just only small clinical studies and a few meta-analyses comparing the 2 surgical techniques for C1-2 posterior fusion have been reported.

Methods: We searched the Cochrane, Embase, and Medline databases for articles comparing the intraoperative and postoperative outcomes of TAS and SF for C1-2 posterior fusion with April 14, 2022, as the publication cutoff date. The odds ratio (OR) and standardized mean difference were used to analyze differences in outcomes between the 2 abovementioned surgical techniques.

Article Synopsis
  • Spinal cord injury disrupts the autonomic nervous system by blocking communication between sensory and motor nerves, and current research is exploring ways to promote neuroregeneration.
  • This study focused on the therapeutic potential of exosomes from human epidural adipose tissue-derived mesenchymal stem cells (hEpi AD-MSCs) for aiding recovery from spinal cord injury.
  • Results showed that injecting these exosomes improved locomotor functions in rats with spinal cord injury by regulating inflammation and changing the expression of related genes.

Purpose: To suggest a cutoff value of tension related to retear of a repaired chronically contracted rotator cuff and to analyze the correlation between predictive factors and integrity of repair in large to massive contracted rotator cuff tears (RCTs).

Methods: We analyzed arthroscopic rotator cuff repairs for large to massive (>3 cm) contracted RCTs, not amenable to complete repair by standard means with meticulous release, with a minimum of 1 year follow-up. An intraoperative procedure was designed for the estimation of repair tension using a tensiometer.
