Background: Palmar finger or pulp defects require coverage with glabrous tissue to achieve a good match with the lost tissue. The management of multiple finger palmar or pulp defects is challenging because these defects may not always be suitable for local or pedicled flaps. In such situations, syndactylizing free or pedicled flaps can be used.

Article Synopsis
  • Researchers developed patient-specific 3D finite-element models to analyze stress distribution in the congruent-arc Latarjet (CAL) and traditional Latarjet (TL) surgical techniques in shoulder procedures, particularly focusing on different arm positions and glenoid defects.
  • The study involved 10 adult patients and simulated various bone defect scenarios (25% and 35%) in the anterior glenoid rim to compare stress patterns in the coracoid grafts between the two techniques.
  • Results indicated that while TL produced greater overall stress on the graft, CAL showed a risk of insufficient bone stimulation at the graft interface, potentially increasing the chances of graft failure or osteolysis.

Objective: The aim of this study was to analyze and classify hypertrophy seen in vascularized fibula flaps used for reconstruction of tubular bone defects.

Methods: Thirty-three patients who underwent a vascularized fibula flap for the reconstruction of massive bone defects of the upper or lower extremity long bones were retrospectively reviewed and included in this study. There were 24 lower extremities (21 tibial and 3 femoral) and 9 upper extremities (4 humeral, 2 radial and 3 ulnar) reconstructions in this series.

Article Synopsis
  • - The study assessed the outcomes of delayed open reduction and K-wire fixation in patients with bony mallet finger injuries over a 10-year period, involving 19 patients with a median age of 24.8 years.
  • - Results showed that after a median of 41 days from injury to surgery, all patients achieved bone union, with the majority having good to excellent functional scores according to the Crawford criteria.
  • - The findings indicate that the procedure can effectively restore joint function with low complication rates, and success may depend on the size of the fracture fragment.

Objective: The aim of this study was to analyze the outcomes of revision surgery following replantation of single digital amputations.

Methods: In this study, first, a total of 403 patients (339 male, 64 female; mean age=28 years; age range=1-76) in whom a single finger replantation was performed were retrospectively reviewed, and then 60 patients with arterial or venous insufficiency in whom revision surgery was performed were reanalyzed. The second finger was observed to be the most injured one (32.

Purpose: To compare five different repair techniques for extensor tendon zone III modified Kessler (MK), double-modified Kessler (DMK), modified Kessler epitendinous (MKE), double-modified Kessler epitendinous (DMKE), and running-interlocking horizontal mattress (RIHM) in terms of shortening, stiffness, gap formation, and ultimate load to failure.

Methods: A total of 35 human cadaver fingers were randomly assigned to five suture techniques with 7 fingers each and were tested under dynamic and static loading conditions.

Results: DMK was found to be superior over MK in terms of ultimate load to failure (36 N vs.

Purpose: If there are no veins available in a distal amputation, an artery-only replantation is performed, and an external bleeding method is commonly used. We conducted a survival analysis in a large series of artery-only replantations and compared 2 different external bleeding methods in artery-only distal replantations: nail matrix or hyponychial area bleeding and pulp skin area bleeding, which we have called the crater method.

Methods: Two hundred twenty-eight artery-only distal finger replantations in 199 patients were included in the study.

We present the treatment course of a 29-year-old male patient with for a Type 3 FDP avulsion (Jersey's finger) of a fifth finger treated with umbrella handle technique. The patient had a volar base fracture of distal phalanx with dorsal subluxation of DIP joint after a fall. Following open reduction of the FDP avulsion fracture and fixation was achieved with a 0.

Objective: There has been no consensus in literature for the ideal flexor tendon repair technique. The results of zone 2 flexor tendon lacerations repaired primarily by 4 strand Modified Kessler core suture and epitendinous interlocking suture technique followed by Modified Kleinert protocol were investigated.

Methods: 128 fingers of 89 patients who had flexor tendon laceration in zone 2 built the working group.

Unlabelled: We report techniques and survival incidence of three subtotally and nine completely degloved fingers in seven patients. We performed end-to-end arterial repairs in seven fingers, vein graft repairs for arteries in two fingers, arteriovenous anastomoses in three fingers. End-to-end vein anastomosis was performed in all fingers.

Venous flaps are flaps by which tissue perfusion is accessed through the venous network. Despite originally being questioned due to potential perfusion problems, as the dynamics of tissue perfusion have been more fully comprehended, venous flaps appear to have a far wider range of application than first thought. In our study, we analyzed the clinical results of the applications of free arterialized venous flaps along with the factors that can affect flap survival.

Article Synopsis
  • Multiple soft tissue finger defects are challenging to treat, often involving tendons and bones, and can lead to vascular issues.
  • In a study of seven patients with such injuries, all sustained damage from machinery, resulting in defects on multiple fingers.
  • The treatment involved using arterialized venous flaps from the forearm, successfully restoring function and appearance without any flap loss over an average follow-up of 12 months.
