RESUMEN
The aim of this study was to compare the closed reduction interfragmentary pinning method (IPM) with the extension block technique (EBT) for bony mallet finger. Patients who underwent mallet finger operations were screened retrospectively for the following inclusion criteria: Doyle type 4c, age between 18 and 75 years, less than 4 weeks to surgery, and more than 1 year of follow-up time. Group I underwent a closed reduction IPM, and group II underwent the EBT. Lateral radiographs taken during the preoperative and final examination were used to evaluate the size and amount of displacement from the distal interphalangeal (DIP) joint and the dorsal fragment as well as the articular surface. Operation times were compiled from patient records. During the final examination, pain and DIP joint range of motion (ROM) were assessed and complications were recorded. The Crawford criteria were used for functional results. Fifteen patients in group I (8 men, 7 women) and 17 patients in group II (10 men, 7 women) were evaluated. Age, gender, time to surgery and follow-up time showed no statistically significant differences between the two groups. The differences in fragment size, preoperative and postoperative joint displacement, amount of dorsal displacement and DIP joint ROM were not statistically significant between the two groups. However, the operation time was significantly shorter time in group I than in group II (p=0.000). The average time to fracture union was significantly longer in group I (7.3 weeks) than in group II (6 weeks) (p=0.013). The EBT has faster time to union and is a safer method with lesser risk of arthritis and fragmentation. The IPM can be an alternative with shorter operation time, less pin bed infection and nail bed damage, especially in Doyle type 4c cases with large fragments.

Arthrodesis of the proximal interphalangeal joint is a proven technique for treating of a range of pathological conditions, including osteoarthritis. There are multiple surgical procedures. A biomechanical study was conducted to compare the stability of a compression wire to intraosseous wiring for the arthrodesis. Seventeen formalin-fixed human fingers were randomly assigned into two groups and the bone mineral density was determined. Arthrodesis in 20° flexion was performed using an oblique compression wire (n=8) or intraosseous wiring (n=9). The stability of the arthrodesis was tested by applying a tensile bending force until failure. The mean force needed to fail the compression wire arthrodesis and intraosseous wire arthrodesis was not significantly different (76.2N, SD 31N and 63.0N, SD 28N). There was no correlation between bone density and force to failure. The compression wire was within the approximate range achieved by intraosseous wiring in withstanding substantial force before failure. From a biomechanical point of view, a compression wire is feasible for PIP arthrodesis.

The aim of this retrospective study was to compare the results of arthroscopic dorsal capsulodesis performed with or without temporary K-wiring to treat patients who had sustained scapholunate ligament injuries. Our case series included 30 patients with an average age of 37 years (range: 19-55) of whom 12 were female. Dorsal scapholunate capsulodesis was carried out in all patients. In 15 patients, splint immobilization only was used (group I). For the remaining 15 patients, supplementary scapholunate and scaphocapitate K-wiring was performed (group II). The outcomes, whether K-wiring was used or not, were not as good as the outcomes of other published studies. In our study, the reported QuickDASH score was on average higher than 20/100, pain score was higher than 2/10, grip strength was less than 70% of the contralateral side. There was one postoperative complication in the first group and three complications in the second group; five cases of DISI were reported in the first group and three in the second group. There were no significant differences between the two groups. Based on our findings, supplementary K-wiring is not necessary when a dorsal scapholunate capsulodesis is performed. The outcomes of our study were not as good as those of other published series, potentially due to a shorter follow-up and the more severe ligament injuries in our case series.

The aim of our study was to evaluate an original surgical technique for the treatment of fifth metacarpal neck fractures: elastic retrograde intramedullary percutaneous pinning (ERIPP). From January 2014 to January 2016, patients with a fifth metacarpal neck fracture with greater than 30° volar displacement and/or clinodactyly were included. All patients underwent an ERIPP procedure. With this technique, K-wires are used as joysticks to assist reduction when the Jahss maneuver is insufficient. Clinical evaluation incorporated the DASH score, range of motion and grip strength at 3months. Radiographic evaluation comprised apex dorsal angulation and metacarpal shortening at 1month and 3months. Thirty-two patients were included in the study. All fractures were healed after a mean of 5 weeks (range 4-7). The DASH score was less than 30 for all patients, indicating an absence of disability. There were no differences in grip strength at 3months between the injured and the contralateral hand. There was less than 10° extension deficit in the metacarpophalangeal joint. In our experience, retrograde percutaneous pinning is a stable, compressive fixation method with effective reduction of displaced fifth metacarpal neck fractures. However, this result needs to be confirmed in comparative studies.

Over-reduction is a classical complication following pinning of distal radius fractures. Indeed, the pinning techniques derived from Kapandji's technique do not allow anterior stabilization. A literature review and our experience show that it is an underestimated complication that can affect up to one-third of cases, but that is well tolerated if the anterior tilt is less than 20°. Excessive angulation of the dorsal intrafocal K-wires becomes a significant risk factor beyond 60°. Volar comminution of the fracture is an obvious predisposing factor. We will outline our ideas on the topic and present a new pinning technique, which has reduced the over-reduction rate to below 3 %: multiple mixed pinning combines two dorsal intrafocal K-wires with two trans-styloid K-wires along the anterior and posterior cortices of the radius to provide true sagittal stabilization of the fracture. This technique is suitable for fractures without major instability or associated anterior comminution-Milliez types 1 and 2 are its best indications. In our practice, there still is a place for pinning of non-complex fractures in young active subjects. More than 20° malunion in flexion can lead to symptoms; in this instance, isolated opening osteotomy of the radius is the most suitable technique.

Unstable distal phalanx fractures are typically treated by pinning of the distal phalanx or the distal interphalangeal joint (DIP). Complications include unstable fixation, K-wire migration, septic arthritis and osteoarthritis. To limit these complications, we wanted to explore the benefits of using locked extra-articular DIP pinning. The cohort consisted of 12 patients (mean age 36.3 years) who had an extra-articular (6 cases) or intra-articular distal phalanx fracture (6 cases). All patients were treated surgically with a construct consisting of two connected K-wires: one was placed inside the shaft of the distal phalanx and the other was placed perpendicular to the middle phalanx. The K-wires were removed after 1 month. After an average follow-up of 19.9 weeks, pain was 0.4/10 and the QuickDASH score was 7.41/100 on average. The range of motion was, on average, 30.0° less than the contralateral uninjured side for active flexion, 8.8° less for active extension, 32.0° less for passive flexion and 4.1° less for passive extension. The overall hand strength averaged 85.2% of the contralateral one. One secondary displacement occurred but there were no infections. In all, these findings suggest that locked extra-articular DIP pinning is a simple and reproducible surgical treatment for distal phalanx fractures. LEVEL OF EVIDENCE: IV.
