headless compression screw

BACKGROUND: Arthrodesis of finger joints is often the last line of treatment of severe pain due to osteoarthritis, rheumatoid arthritis, or mallet finger. At the Department of Orthopedic and Hand Surgery, Örebro University Hospital (ÖUH) in Sweden, the Kirschner-wire technique was standard until 2020, when the headless compression screw technique was introduced as a complement. There is no consensus on which method is superior. The purpose of this study was to examine the outcomes and complications associated with distal interphalangeal (DIP) joint and thumb interphalangeal (IP) joint arthrodesis, and to see whether these correlated with patient-dependent and treatment-related factors...

INTRODUCTION: Hand fractures are associated with significant morbidity. Current management standards often result in prolonged immobilization, stiffness, and delayed return to functional use. Intramedullary (IM) compression screws offer minimal soft tissue disruption and early postoperative active motion. In this study, we describe our outcomes after intraosseous fracture fixation using IM cannulated headless screws for a multitude of fracture patterns. METHODS: This study is a retrospective review of patients who underwent IM screw placement for fixation of metacarpal and phalangeal fractures by a single surgeon from 2017 to 2022...

PURPOSE: Coronal shear fractures of the distal humerus involving the capitellum and trochlea are rare injuries. Internal fixation with headless compression screws provides a stable construct facilitating early mobilisation. Our study aimed to identify the key determinants of both radiological and functional outcomes of patients with distal humerus coronal shear fractures treated with internal fixation. METHODS: A retrospective analysis of 61 patients with distal humerus coronal shear fractures who were treated surgically was done...

PURPOSE: Proximal interphalangeal (PIP) joint arthrodesis is a procedure employed to address arthritis, instability, and deformity. Multiple fixation methods are available to maintain stability across the arthrodesis interval, including headless compression screws (HCSs), tension band wiring (TBW), plating, and Kirschner wire constructs. The purpose of this study was to compare the biomechanical properties of the HCS and TBW techniques. METHODS: Thirty-two nonthumb digits from the paired upper limbs of four fresh frozen cadavers were divided into pairs, matching contralateral digits from the same specimen...

BACKGROUND: An olecranon stress fracture (OSF) is a rare injury most commonly seen in high-level overhead throwing athletes with no clear consensus on surgical treatment. The most common surgical treatment described in the literature is cannulated screw fixation but there have been high rates of reported hardware irritation and need for subsequent hardware removal. HYPOTHESIS/PURPOSE: This study describes a novel surgical technique in the treatment of OSFs in high-level throwing athletes using retrograde headless compression screws...

OBJECTIVE: To compare the biomechanical stability of three cross-bridge headless compression screws and locking plates in the fixation of Mason type Ⅲ radial head fractures by finite element method. METHODS: Using reverse modeling technology, the radial CT data and internal fixation data of a healthy 25-year-old male were imported into the relevant software. Three-dimensional finite element model of 3 cross-bridge headless compression screws and locking plates for MasonⅢ radial head fractures were established, and the radial head was loaded with 100 N axial loading...

Background  Single- or bicolumn limited intercarpal fusion, also called one- or two-column fusion, has been introduced as an alternative to four-corner fusion. The rationale behind this is obtaining less need for bone grafting and consequently improving the chances of the union. Method  From August 2014 to October 2020, 45 consecutive patients (15 women), with a mean age of 58.4 years (range: 35-79), have been treated for scapholunate advanced collapse or scaphoid nonunion advanced collapse wrist...

OBJECTIVE: To describe fluoroscopically-assisted closed reduction and percutaneous fixation of sacroiliac-luxation (SIL) in cats and report radiographic results and long-term functional outcomes. STUDY DESIGN: Retrospective clinical study. ANIMALS: Eleven cats. METHODS: Percutaneous fixation of 17 SILs in 11 cats was performed with 2.4 mm headless cannulated compression screws under fluoroscopic guidance. Luxation-reduction, screw placement and purchase within the sacral body, pelvic canal diameter ratio (PCDR) and hemipelvic canal width ratio (HCWR) were assessed on pre- and postoperative radiographs...

The purpose was to compare clinical and radiological outcomes between two fixation techniques used to treat extra-articular fractures involving the base of the thumb metacarpal: retrograde intramedullary cannulated headless screw (RICHS) and locking plate (LP). Fifty-one patients who underwent RICHS (n = 22) or LP fixation (n = 29) from January 2010 through 2020 were included in this retrospective case-control study with mean follow-up 39 months. No inter-group differences were observed comparing mean time to radiological union, grip strength, range of motion, pain severity or QuickDASH scores...

OBJECTIVE: Treating high-level athletes involves a balance between early and safe return to play. Various types of protective immobilization have been recommended after operatively treated Bennett's fracture. The purpose of this study was to investigate if hand-based immobilization offers protection equivalent to forearm-based immobilization. MATERIALS AND METHODS: A cadaveric model of Bennett's fracture was created in 8 fresh-frozen, cadaveric forearms. Osteosynthesis was performed using a single headless compression screw...

INTRODUCTION AND IMPORTANCE: Lunate fractures without associated dislocations are rare injuries, combination scaphoid-lunate fractures without an associated dislocation are even more rare of which few are reported in the literature. CASE PRESENTATION: This case report describes a 16-year-old otherwise healthy male with ipsilateral scaphoid and lunate fractures after punching a goalpost with his left hand, for which he had surgical management. This patient had a successful treatment with two headless compression screws through a single extended carpal tunnel approach...

PURPOSE: Headless compression screws (HCS) have a variable thread pitch and headless design enabling them to embed below the articular surface and generate compression force for fracture healing without restricting movement. Locking screws have greater variety of dimensions and a threaded pitch mirroring the design of the HCS. The objective of this study is to determine whether locking screws can generate compression force and compare the compressive forces generated by HCS versus locking screws...

Metacarpal fractures are common and may require operative treatment; however, there is no gold standard fixation technique. K-wires are used for simplicity and flexibility but require immobilization and can lead to complications. Dorsal plating provides greater stability than K-wires but is subject to its own limitations. Intramedullary threadless nails have reduced time to union and improved range of motion (ROM) but may not provide the stability of plating. Intramedullary screws allow rapid return to activity and increased stability; however, compression forces may shorten metacarpals, producing non-anatomic reduction...

OBJECTIVES: Headless screw fixation used to treat metacarpal neck and metacarpal shaft fractures is gaining popularity. The aim of the study is to determine the proportion of the metacarpal head articular surface that is compromised during retrograde insertion of headless screws. METHODS: Metacarpal screw fixation through a metacarpal head starting point was performed using fluoroscopic guidance on 14 metacarpals. Headless compression screws, with a tail diameter of 3...

AIM: The study aimed to compare the outcomes of Open Reduction and Cannulated Screw Fixation (ORCF) and Open Reduction and Tension Band Wire Fixation (ORTF) for treating minimally displaced patellar fractures, with the intention to discern the more efficacious surgical method in terms of various clinical and radiographic parameters. METHODS: The research was a retrospective controlled trial encompassing 63 patients, culminating in a final data set of 52 patients with transverse patellar fractures with less than 8 mm of displacement...

PURPOSE: Hamate fractures are rare fractures of the wrist and there is still no consensus on the optimal treatment for these fractures, especially hook of hamate fractures. Herein, the authors present a case study of a series of patients who were treated with closed reduction and minimally invasive percutaneous fixation under robot navigation. METHODS: This retrospective study reviewed 14 patients who had nondisplaced or minimally displaced hamate fractures on computerized tomography images and were treated using the treatment in our centre from November 1, 2019, to October 31, 2022...

Distal radius fractures are common injuries that often require surgical intervention. Commonly, these fractures are fixed using open reduction internal fixation with plating and screws. This often requires a more extensive soft tissue dissection and exposure. In contrast for certain cases, percutaneous headless compression screws may be appropriate. We present a technique for minimally invasive arthroscopic-assisted reduction and percutaneous screw fixation with an extremity traction device. A case is provided to demonstrate the technique as a viable option for the treatment of intra-articular distal radius fractures...

OBJECTIVES: Scaphoid nonunion remains a challenging problem to manage with no general consensus on its treatment recommendations. We propose a novel minimally invasive (MIS) technique of arthroscopic bone grafting (ABG) with robot-assisted fixation for the treatment of scaphoid nonunions. METHODS: Patients with radiographically proven scaphoid nonunion treated by this novel surgical technique were included. Following arthroscopic debridement and iliac crest bone grafting, the scaphoid was fixed percutaneously using either multiple Kirschner (K)-wires or a headless compression screw using a robotic navigation system...

Second-generation headless compression screws (HCSs) are commonly used for the fixation of small bones and articular fractures. However, there is a lack of biomechanical data regarding the application of such screws to radial head fractures. This study evaluated the mechanical properties of the fixation of radial head fractures using a single oblique HCS compared with those obtained using a standard locking radial head plate (LRHP) construct and a double cortical screw (DCS) construct. Radial synbone models were used for biomechanical tests of HCS, LRHP, and DCS constructs...
