Vascularized hemi-hamate graft: Anatomic description of a novel pedicled osteo-chondro-ligamentous flap for proximal scaphoid reconstruction.

Scaphoid proximal pole destruction remains a surgical challenge owing to its high propensity for nonunion and osteonecrosis. The hemi-hamate graft has shown promising results in addressing this issue. However, long-term results of non-vascularized composite grafts remain uncertain.

Arthroscopic suture in the management of palmar midcarpal instability.

Aims: Patients with midcarpal instability are difficult to manage. It is a rare condition, and few studies have reported the outcomes of surgical treatment. No prospective or retrospective study has reported the results of arthroscopic palmar capsuloligamentous suturing.

Scaphoid proximal pole ejection in perilunate injury: a case report and pathophysiological hypothesis.

Isolated ejection of the scaphoid proximal pole in perilunate injuries is rare, with only 4 reports in the literature, and does not correspond to the biomechanical situations in the Herzberg or Mayfield classifications. Bone ejection incurs a risk of avascular necrosis despite good osteosynthesis, notably because of precarious vascularization. We present a case of scaphoid proximal pole ejection and a theoretical hypothesis of the biomechanics of this injury.

Free Fibula Flap in Traumatic Femoral Bone Reconstruction: A 10-year Review.

Introduction: The loss of femoral bone substance represents a major therapeutic issue. When the loss of bone substance is extensive, or the local condition is unfavourable, there are few satisfactory solutions. In this study, we share our experience of large femoral bone reconstruction by free fibula flap.

All-Dorsal Arthroscopic Ligamentoplasty (ADAL) in Scapholunate Instability Management: Surgical Technique.

In advanced scapholunate instability, a scapholunate repair by open or arthroscopic ligamentoplasty is indicated. Although the radiographic results and functional scores are more or less satisfactory for open ligamentoplasty, it is often responsible for a decrease in joint amplitude postoperatively. Arthroscopic techniques are therefore of great interest, since they respect the joint capsule, but they remain technically difficult and demanding surgeries, requiring a good deal of experience in arthroscopy and using bone tunnels that are potentially a source of complications, as well as pinning to the palmar side of the wrist, which is potentially dangerous for the palmar structures of the wrist.

Correlation between dorsal capsulo-scapholunate septum (DCSS) lesion and predynamic scapholunate instability.

Objective: Scapholunate instability is the most common ligament injury of the wrist. In case of predynamic instability, diagnosis can be difficult, even under arthroscopy. Scapholunate instability is not the result of an isolated injury to the scapholunate interosseous ligament.

Targeted partial arthroscopic trapeziectomy with temporary distraction: a retrospective study with 5-year follow-up.

Targeted partial arthroscopic trapeziectomy with temporary distraction is a minimally invasive treatment for trapeziometacarpal osteoarthritis. We performed a retrospective single centre study from March 2011 to May 2022 and included patients with at least 5 years of follow-up. A failure was defined as a patient requiring a second procedure.

Immediate Proximal Row Carpectomy for Severe Perilunate Dislocation Injuries: A Minimum 5-Year Follow-Up.

In patients with perilunate injuries (PLI) with multiple ligamentous and bony injuries involving the proximal carpal row, open reduction and internal fixation (ORIF) can be difficult and lead to poor functional outcomes. Proximal row carpectomy (PRC) is an alternative procedure that has been used for severely comminuted fractures. The aim of our study is to evaluate the long-term functional outcome (minimum 5 years) of patients that underwent an emergency PRC for PLI.

Relationship between trapeziometacarpal joint morphological parameters and joint contact pressure: a possible factor of osteoarthritis development.

The trapeziometacarpal (TMC) joint is the one of the hand joints that is most affected by osteoarthritis (OA). The objective of this study was to determine if specific morphological parameters could be related to the amount of pressure endured by the joint which is one of the factors contributing to the development of this pathology. We developed 15 individualized 3D computer aided design (CAD) models of the TMC joint, each generated from the CT scan of a different participant.

Surgical Technique: Wide Arthroscopic Dorsal Capsuloligamentous Repair for Advanced Scapholunate Instability.

In the most advanced cases of scapholunate instability with dynamic or static signs, classical arthroscopic repair seems impossible. Ligamentoplasties or open surgery procedures are technically demanding, hampered by significant operative complications and often stiffening. Therapeutic simplification is therefore necessary for the management of these complex cases of advanced scapholunate instability.

Wide arthroscopic dorsal capsuloligamentous repair in patients with severe scapholunate instability.

A conventional arthroscopic capsuloligamentous repair is a reliable surgical solution in most patients with scapholunate instability. However, this repair does not seem to be sufficient for more advanced injuries. The aim of this study was to evaluate the functional results of a wide arthroscopic dorsal capsuloligamentous repair (WADCLR) in the management of severe scapholunate instability.

Does the choice of the optic portal influence the radiographic and early functional results in acute acromioclavicular disjunctions?

Exposure of the coracoid process during arthroscopic stabilization of acute acromioclavicular disjunctions (ACDs) can be achieved either by passing an extra- articular optical portal through the subacromial space or by an intra-articular optical route through the glenohumeral joint with opening of the rotator interval. The objective of our study was to compare the impact on the functional results of these two optical routes. This was a retrospective, multicentre study that included patients operated on for an acute acromioclavicular disjunction arthroscopically.
