Article Synopsis
- A deep learning algorithm was developed to analyze distal radius fractures using X-ray images, and its effectiveness was compared with measurements taken by an orthopedic hand surgeon.
- The study utilized 634 wrist X-ray images, with 507 for training and 127 for testing, to segment the radius and ulna and measure specific radiologic parameters accurately.
- Results showed high accuracy rates (over 99%) for segmentation, and strong correlations (Pearson and intraclass correlation coefficients) between the algorithm's measurements and the manual methods used by the surgeon.
Locking of the Metacarpophalangeal Joint of the Thumb Caused by Entrapment of the Radial Sesamoid Bone.

Article Synopsis
- Locking of the thumb's metacarpophalangeal (MCP) joint can occur due to dorsal subluxation from hyperextension injuries, causing it to be stuck in mild hyperextension.
- The study discusses four cases where patients experienced locked MCP joints due to the radial sesamoid being caught after injuries involving hyperextension or forced flexion.
- It is suggested that if thumb movement is restricted after such injuries, evaluating the radial sesamoid is crucial, and excising it may help unlock the joint.
Article Synopsis
- Volar plate avulsion fractures of the proximal interphalangeal (PIP) joint are common injuries typically treated conservatively, but this approach may fail if the fracture fragments are significantly displaced or rotated.
- A study analyzed 88 cases of such fractures to compare outcomes between successful conservative treatments and those needing surgical intervention after around 75 days.
- Results showed that joint dislocation and more severe displacement or rotation were linked to treatment failure, but those requiring surgery experienced improved pain and range of motion post-excision.
Background: The restriction of wrist motion results in limited hand function, and the evaluation of the range of wrist motion is related to the evaluation of wrist function. To analyze and compare the wrist motion during four selected tasks, we developed a new desktop motion analysis system using the motion controller for a home video game console.
Methods: Eighteen healthy, right-handed subjects performed 15 trials of selective tasks (dart throwing, hammering, circumduction, and winding thread on a reel) with both wrists.
Article Synopsis
- * Malalignments can cause mechanical strain, weakening ligaments, and instability in the wrist, with radial corrective osteotomy proposed as a potential treatment.
- * Two cases are highlighted where traditional treatments failed, revealing that fixed lunate flexion deformity may lead to arthritis in the radiolunate joint post-injury.
Purpose: To compare the extramedullary femoral alignment guide system with the conventional intramedullary alignment guide system for bleeding and transfusion rate after total knee arthroplasty (TKA).
Materials And Methods: Forty-nine female TKA patients were randomized into two groups: intramedullary (IM) group vs. extramedullary (EM) group.
Background: The Korean version of the Disability of the Arm, Shoulder and Hand Questionnaire (K-DASH) was recently validated, but its responsiveness, which is the degree to which an instrument is sensitive to change, has not been thoroughly evaluated in a specific condition in Koreans. We evaluated the responsiveness of the K-DASH in a homogenous cohort of patients with carpal tunnel syndrome (CTS) and we compared it with that of the disease-specific Carpal Tunnel Questionnaire (CTQ).
Methods: Fifty-six patients with CTS prospectively completed the K-DASH and CTQ before and 6 months after surgery.
We attempted to determine whether muscle excursion observed during operation can be a prognostic indicator of muscle recovery after delayed tendon repair in a rabbit soleus model. Eighteen rabbits underwent tenotomy of the soleus muscles bilaterally and were divided into three groups according to the period from tenotomy to repair. The tendons of each group were repaired 2, 4, and 6 weeks after tenotomy.

Purpose: To assess the radiographic progression of degenerative lumbar scoliosis after short segment decompression and fusion without deformity correction.
Overview Of Literature: The aims of surgery in degenerative lumbar scoliosis are the relief of low back and leg pain along with a correction of the deformity.
Background: Factors regarding patient willingness to undergo or avoid joint replacement have been studied; however, these factors have not been studied in patients with carpal tunnel syndrome. To further understand the aspects that are important for a patient with carpal tunnel syndrome in deciding whether to have surgery, we identified factors that affect this decision in women and that are not related to Workers' Compensation status.
Methods: We retrospectively reviewed 282 female patients with electrophysiologically confirmed carpal tunnel syndrome without a known cause who were recommended for carpal tunnel release by a single hand surgeon in a tertiary medical setting.
Purpose: The loop-tendon method for the stabilization of tendon transfers or grafts has been demonstrated previously to have greater initial tensile strength than that of the end-weave method. To our knowledge, a comparison of the mechanical strengths of these methods over the early postoperative period has not been made. The purpose of this study was to compare the mechanical strengths of loop-tendon and end-weave methods of repair during the early postoperative period in rabbit hind limb tendons.

Hypothesis: Knotless suture anchor is a viable alternative for arthroscopic Bankart repair, but postoperative radiologic findings of radiolucency around anchors are correlated with poor clinical results.
