Flexor Digitorum

Background: The transfer of flexor-to-extensor is widely used to correct lesser toe deformity and joint instability. The flexor digitorum longus tendon (FDLT) is percutaneously transected at the distal end and then routed dorsally to the proximal phalanx. The transected tendon must have enough mobility and length for the transfer. The purpose of this study was to dissect the distal end of FDLT and identify the optimal technique to percutaneously release FDLT. Methods: Eight fresh adult forefoot specimens were dissected to describe the relationship between the tendon and the neurovascular bundle and measure the width and length of the distal end of FDLT. Another 7 specimens were used to create the percutaneous release model and test the strength required to pull out FDLT proximally. The tendons were randomly released at the base of the distal phalanx (BDP), the space of the distal interphalangeal joint (SDIP), and the neck of the middle phalanx (NMP). Results: At the distal interphalangeal (DIP) joint, the neurovascular bundle begins to migrate toward the center of the toe and branches off toward the center of the toe belly. The distal end of FDLT can be divided into 3 parts: the distal phalanx part (DPP), the capsule part (CP), and the middle phalanx part (MPP). There was a significant difference in width and length among the 3 parts. The strength required to pull out FDLT proximally was about 168, 96, and 20 N, respectively, for BDP, SDIP, and NMP. Conclusion: The distal end of FDLT can be anatomically described at 3 locations: DPP, CP, and MPP. The tight vinculum brevis and the distal capsule are strong enough to resist proximal retraction. Percutaneous release at NMP can be performed safely and effectively. Clinical Relevance: Percutaneous release at NMP can be performed safely and effectively during flexor-to-extensor transfer.

ABSTRACT: Laminitis is a severe podal affection, which pathophysiology remains partially renowned. Ischemic, enzymatic, metabolic and inflammatory mechanisms are connected to the development of laminar lesions. However, few therapeutic measures are effective to prevent or control the severity of acute laminitis and its prodromal stage, which often determines serious complications such as rotation and/or sinking of the distal phalanx and even the loss of hoof. The purpose of this study is to compile the actual knowledge in respect to the pathophysiology and treatment of equine laminitis.

Digital Blood Flow

Caffeine has been shown to increase mean blood pressure, but studies documenting the effect of caffeine on digits are lacking. We evaluated the effect of caffeine on digital blood pressure and pulse volume in normal volunteers. In the first part of the study, 24 subjects were given water containing either 200 mg of caffeine or placebo. Bilateral brachial and middle finger digital pressures were measured at room temperature before ingestion and at 30 and 60 minutes after ingestion. In the second part of the study, pulse volume recordings (PVRs) were obtained in 24 subjects at the level of the distal phalanx of the middle finger of one hand immediately prior to beverage ingestion and at 10 minute intervals for 90 minutes. Differences in mean digital systolic pressure, digital/brachial index, or PVR amplitude between the control and caffeine groups were not statistically significant. The administration of caffeine was found not to alter the haemodynamics of digital blood flow or digital pressure in this population.

Abstract Purpose To report the clinical and radiographic results of arthrodesis of relatively small-sized distal interphalangeal joints (DIPJs) using only K-wire fixation. Patients and methods Between January 2000 and December 2018 28 arthrodesis in 21 patients (9 males and 12 females with an average age of 52.1 years) with relatively small-sized DIPJs were performed using only K-wires. Data on patient’s characteristics, such as age, sex, affected finger, and the number and size of the used k-wires were collected from the medical database. The narrowest diameter of the cortex and medulla of the distal phalanx was measured on preoperative plain radiographs. The time to union and the arthrodesis angle was determined using serial X-ray radiography follow-up. Preoperatively and at the latest follow-up examination, pain using the visual analogue scale (VAS) and the quick DASH score was registered. In addition, complications were investigated. Results Average follow-up period was 11.4 months. The small finger was mostly affected (n = 12; 42.9 %). The narrowest diameters of the distal phalanx cortex and the medulla measured on preoperative X-ray images were 2.8 mm (SD 0.5) and 1.2 mm (SD 0.4), respectively. Seven fusions were done with use of 1 K-wire, 20 with 2 (71.4 %), and 1 with 3 K-wires. The most common K-wire sizes were 1.1-inch (24 K-wires = 48 %), and 0.9 inch (21 K-wires = 42 %) The preoperative VAS score and quick DASH score improved from 6.1 (range: 0–9) and 25.8 (range: 2–38) to 0.4 (range: 0–2) and 3.4 (range: 0–10.2), respectively. 25 (89.3 %) out of 28 fingers achieved bony union in an average of 96.1 days (range: 58–114) with three non-union. Conclusion Arthrodesis of small DIPJs with K-wire fixation has a high success rate. Therefore, we suggest K-wire fixation as an acceptable alternative for patients with a small phalanx which may be at risk of mismatch with bigger implants. However, concerns remain in terms of fusion delay with K-wire only fixation.
