Concentrated autologous bone marrow injection in the surgical treatment of scaphoid non-union.

New surgical techniques for the treatment of scaphoid non-union, developed in the last two decades, now enable a healing rate of 80-90%. However, no consensus exists for the surgical treatment of non-union. On the other hand, regenerative medicine techniques have enriched the therapeutic armamentarium for non-union, especially in the lower limbs, with the use of autologous concentrated bone marrow injection using autologous osteogenic precursors to create a favorable microenvironment for bone healing.

Treatment of long finger metacarpophalangeal arthritis using HAPY® pyrocarbon interposition implants: a study of 34 cases.

Introduction: Destruction of the metacarpophalangeal joint can result in disabling pain and stiffness. Several therapeutic options are available, including pyrocarbon interposition implants. The primary endpoint of this study was assessment of clinical and radiographic outcomes in 34 patients treated with HAPY® pyrocarbon interposition implants (Tornier, Grenoble, France) with a minimum follow-up of 3 years.

Posterior thigh compartment syndrome secondary to proximal hamstring avulsion.

Introduction: Thigh compartment syndrome is a rare clinical entity that requires urgent medical and surgical management due to its potentially severe medical and legal consequences. Although it typically affects a classic patient demographic-most often a young adult following a traffic accident.

Presentation Of Case: This case is unique in that it stems from a compressive hematoma secondary to an avulsion of the proximal hamstring tendon.

Vascular supply of the radial nerve and its terminal branches: an anatomical study.

Purpose: The aim of this cadaveric study was to further describe the vascular supply of the radial, posterior interosseous and superficial radial nerves.

Methods: 11 cadaveric upper limbs, injected with colored latex, were dissected. Vascular afferents to the radial nerve, superficial radial nerve (SRN) and posterior interosseous nerve (PIN) were described and located.

Distal radius fracture osteosynthesis by volar locking plate: influence of epiphyseal screw positioning on risk of loss of reduction.

Ulnar variance is an important radiological parameter for good functional outcome after distal radius fracture osteosynthesis. Secondary loss of reduction due to radial shortening is a common complication after volar locking plate fixation. Some authors recommend beginning by placing the most ulnar epiphyseal screw, ensuring that it is positioned as close as possible to the distal radioulnar and radiocarpal joints.

Consolidation rate in ulnar shortening osteotomy with the APTUS Wrist plate.

Introduction: Ulnocarpal impaction syndrome causes pain on the ulnar side of the wrist. Various surgical techniques have been described. Ulnar shortening osteotomy is now a standard treatment.

Management of advanced metacarpal aneurysmal cysts: Surgical technique.

The hand is a rare site for aneurysmal bone cysts (ABCs). Depending on their degree of invasiveness, treatment of ABCs ranges from medical therapy to surgical curettage and bone filling. In the most advanced cases, bone resection and reconstruction, with or without adjuvant or neoadjuvant treatment, are indicated.

The role of three-dimensional printing in coronavirus disease-19 medical management: A French nationwide survey.

Objectives: Coronavirus disease-19 (COVID-19) has spread worldwide and poses various challenges to healthcare services. The limited supply of medical and personal-protective equipment has affected the ability of many countries to respond to the crisis. Three-dimensional printing (3DP) is well suited to addressing these shortages.
