HYPOTHESIS: Fixation of a 3-part radial head fracture with cannulated compression screws will show equivalent stiffness to a locking plate under axial load. Debate exists regarding the management of Mason type III fractures, with many believing that open reduction and internal fixation provides advantages over other options. By virtue of their subarticular placement, screw fixation is less likely to cause impingement compared with plate fixation, which can result in loss of rotation and requirement for hardware removal...

Management of proximal pole scaphoid nonunion remains a challenging problem. Multiple surgical techniques have been described, although no treatment has proven superior. Recent studies have questioned the need for vascularized bone grafting, even in in the setting of avascular proximal poles. We present a relatively simple technique of intramedullary autogeneous cancellous bone grafting that does not disturb the intact cortical shell of the nonunion, which has so far provided gratifying clinical results.

PURPOSE: Several operative approaches and various implants for osseous fixation have been described to achieve four-corner fusion of the wrist. Given the discordance and to aid in further standardizing the technique, this study directly compares the outcomes of K-wire, fusion plate, and headless retrograde compressive screw fixations to achieve four-corner arthrodesis. METHODS: Sixty-four patients underwent four-corner fusion over a period of 5 years and were reviewed retrospectively...

BACKGROUND: Fractures of the scaphoid bone are common but can easily be overlooked in standard X‑rays. Inadequate diagnostics and therefore inappropriate treatment of scaphoid fractures often leads to problems in healing with formation of non-union and painful osteoarthritis of the wrist. OBJECTIVE: This review summarizes the current practical recommendations in the diagnostics and treatment of acute scaphoid fractures. METHODS: An analysis and review of selected literature including the current S3 guidelines were performed...

Articular fractures of the elbow require direct reduction and interfragmentary fixation to restore anatomic stability. The fragments are often small, with limited bone stock, hence implants are often placed through the articular surface to gain maximal purchase. Traditional techniques involve the use of countersunk cortical screws or cannulated headless compression screws. We describe a technique in which small locking screws are used independently from a plate as a substitute for headless or other traditional screws...

INTRODUCTION: Scaphoid nonunion remains challenging for hand surgeons. Several treatment options are available such as: non-vascularized or vascularized bone grafting, with or without additional stabilization. In the last few decades, extracorporeal shockwave therapy (ESWT) has become an established procedure for treating delayed and nonunions. Purpose of this retrospective follow-up study was (a) to investigate union rate and clinical outcome of the different implants [either one/two headless compression screws (HCS) or a plate] and (b) union rate and clinical outcome using only surgery, or a combination of surgery and ESWT...

BACKGROUND: Midcarpal arthrodesis is a treatment of choice in patients with midcarpal arthritis. Traditionally a four corner fusion has been favoured, however recent research has shown improved results when the triquetrum and scaphoid are excised. There is no clear evidence as to which remaining bones should be fused or which implants should be used. The purpose of this study is to compare the biomechanics of midcarpal arthrodesis after scaphoid and triquetrum excision, using memory staples or cannulated screws, in recognised construct patterns...

CASE: A 31-year-old Caucasian man presented with a greater arc perilunate variant injury after falling from a friend's shoulders onto an outstretched hand. Imaging revealed a minimally displaced scaphoid waist fracture and a nondisplaced transverse fracture through a previously unrecognized lunotriquetral coalition. A volar intercalated segmental instability (VISI) deformity was present. Open reduction with osseous fixation (a headless compression screw for the scaphoid waist fracture and 3 Kirschner wires across the midcarpal joint) and repair of the torn volar ligaments partially restored the carpal alignment...

Os acromiale is a failure of fusion between 1 or more ossification centers of the scapula and the acromion process. Pain can be caused by motion and impingement of the unfused segment. Several methods for the management of os acromiale have been described. Internal fixation is the most common surgical technique, followed by excision and acromioplasty. We present a novel technique for treatment of symptomatic os acromiale using arthroscopically-guided headless compression screws. This is a viable technique in the management of symptomatic os acromiale due to preservation of the periosteal blood supply and less concern for symptomatic hardware...

BACKGROUND: Arthrodesis of the distal interphalangeal (DIP) joint reliably improves symptomatic arthritis. A range of successful surgical techniques including tension band wiring, plate fixation and headless compression screws have been described and produce stable painless unions. For best functional outcome, the fusion angle should be between 10 and 61 degrees. In the past, it has been difficult to achieve more than 10 degrees of flexion with a headless compression screw. Higher fusion angles have been reported using tension band wiring techniques...

This study is the first biomechanical research of headless compression screws for fixation of vertical shear fractures of the medial malleolus, a promising alternative that potentially offers several advantages for fixation. Vertical shear fractures were simulated by osteotomies in 20 synthetic distal tibiae. Models were randomly assigned to fixation with either 2 parallel cancellous screws or 2 parallel Acutrak 2 headless compression screws (Acumed). Specimens were subjected to offset axial loading to simulate supination-adduction loading and tracked using high-resolution video...
