Nail spicules result from incomplete excision of the nail matrix of the finger. We report a histological study to delineate the surface anatomy of the nail matrix. Sections were cut longitudinally and transversely in 19 fingertips. The proximal midline extent of the nail matrix was measured and expressed as a ratio of the distance from the nail fold to the distal interphalangeal joint. In the lateral sections, the angle subtended between the midline vertical and the lateral extent of the nail matrix was measured. The mean ratio of the proximal extent was 0.55 in the midline and the lateral angular extent was 66°. The authors recommend that excision of the nail matrix should be rectangular, extending to the midlateral lines and proximally to a point three-quarters of the distance from the nail fold to the distal interphalangeal joint crease.

New Surgical Technique

A new surgical technique is described for the treatment of mallet finger deformity which involves the application of a mini external fixator across the distal interphalangeal joint and resection of a portion of the extensor mechanism. We reviewed 19 patients who were treated with this technique, at a mean follow-up period of 36 (range, 24–48) months. The mean extensor lag was 2° (range, −7° to 13°) and the mean flexion range was 70° (range, 20°–90°).

Background: The vast majority of acute closed tendinous mallet injuries are treated with a splint. Very few studies have directly compared splinting versus pinning the distal interphalangeal joint for this injury. The aim of this cohort study is to determine the outcomes of both methods. Methods: A total of 59 patients with acute tendinous mallet injury were retrospectively enrolled (29 patients in conservative treatment and 30 patients in surgical treatment). Conservative treatment was performed using custom-made thermoplastic splint and surgical treatment was conducted with oblique K-wire fixation of the distal interphalangeal (DIP) joint. The DIP joint was immobilized for eight weeks in both treatments. Active ranges of motion of the affected finger and Miller’s classification were evaluated postoperatively. Results: The mean extension lag of the DIP joint in the surgical treatment group was significantly better than it was with conservative treatment (2.1° vs 13.8°). Three patients who were noncompliant with the splint showed poor results, while no patients in the surgical treatment group had a poor result. Conclusions: Surgical treatment with K-wire fixation leads to satisfactory results for acute tendinous mallet injury.

Abstract Background Closed tendinous mallet finger can be treated non-operatively by extension splinting of the distal interphalangeal joint (DIPJ) for 6 to 8 weeks. However, method of conservative treatment in detail differs among various reports, especially in type of orthosis, duration of full-time immobilization and additional night orthotic wear after full-time immobilization. In our institution, full-time Stack splint is applied with distal interphalangeal joint (DIPJ) in extension for 12 weeks and night orthosis is worn for 4 weeks. Purpose The purpose of this study was to evaluate clinical and functional outcomes of tendinous mallet finger using our treatment protocol. Patients and Methods Between March 2007 and December 2017, patients with tendinous mallet finger who were managed conservatively according to our treatment protocol were retrospectively reviewed. A total of 100 patients (101 cases) were enrolled, including 77 males and 23 females. Extension lag was measured before, soon after treatment, and at the final follow-up. Flexion angle of DIP joint was measured at the final follow-up. Patients were clinically evaluated based on the Crawford classification scale and Abouna & Brown criteria. Results The mean age of patients was 40 years and the mean follow-up was 48 months. The mean extension lag was 28.3 degrees initially and 2.6 degrees at the final follow-up. (p-value < 0.001) Flexion angle at the final follow-up was 68.3 degrees. Based on the Crawford classification scale, 56 % of patients had excellent results, and 25 % of patients had good results. According to Abouna & Brown criteria, 78 % of patients had success results and 7.5 % of patients had improved results. Conclusions Wearing orthosis for up to 16 weeks (12 weeks full time and 4 weeks night orthosis) in the treatment of tendinous mallet finger injuries can achieve satisfying result.

This article evaluates the outcome of 42 consecutive zone 1 flexor tendon injuries treated by using micro bone anchors during the period 2003–2008. Patients were rehabilitated using the modified Belfast Regime. The range of motion at the distal interphalangeal joint was assessed using Moiemen’s classification. A total of 56% of patients achieved excellent or good results for range of motion at the distal interphalangeal joint and 23% had a poor outcome. The mean distal interphalangeal joint and proximal interphalangeal joint range of motion were 48° and 96°, respectively. A total of 94% of patients returned back to work by 12 weeks. One patient sustained a tendon rupture and one developed osteomyelitis. The mean QuickDASH score was 13.5 and 81% of patients were satisfied with their outcomes. This is the largest clinical study on the use of bone anchors for zone 1 tendon injuries. Our study demonstrated a low rate of complications and outcomes that compare favourably with other published techniques.

Fifteen patients who underwent percutaneous fixation of mallet fractures of the distal phalanx using compression fixation pins were assessed. Anatomical reduction was achieved in all patients. There were no nonunions. The mean active range of motion of the distal interphalangeal joint was 1° of hyperextension to 69° of flexion. The fixation was stable enough to allow early active motion exercise of the distal interphalangeal joint. This technique results in a good range of motion in a shorter period of time than other treatments.

Periarticular Tissue

We investigated the relative ratios of collagen composition of periarticular tissue of the elbow, wrist, metacarpophalangeal, proximal and distal interphalangeal joints. Periarticulat tissue, which we defined as the ligaments, palmar plate and capsule, was harvested from ten fresh-frozen cadaveric upper limbs, yielding 50 samples. The mean paired differences (95% confidence interval) of the relative ratios of collagen between the five different joints were estimated using mRNA expression of collagen in the periarticular tissue. We found that the relative collagen composition of the elbow was not significantly different to that of the proximal interphalangeal joint, nor between the proximal interphalangeal joint and distal interphalangeal joint, whereas the differences in collagen composition between all the other paired comparisons of the joints had confidence intervals that did not include zero.

The purpose of this study is to determine the normal ranges of radioulnar (i.e. medial-lateral) finger deviations during growth. We retrospectively measured radioulnar interphalangeal joint angles in 6236 properly aligned thumbs and fingers in trauma radiographs of 4720 patients aged 0 to 19 years. The mean interphalangeal joint angle of the thumb was 0.2° (standard deviation 1.5°). The average proximal interphalangeal joint angles were ulnar deviation of 2.5° (1.7°) for the index, ulnar deviation 1.7° (1.5°) for the middle, radial deviation 1.3° (1.8°) for the ring, radial deviation 2.0° (2.8°) for the little fingers. The distal interphalangeal joint angles were ulnar deviation of 2.5° (1.7°), ulnar deviation 2.1° (1.7°), radial deviation 2.1° (1.7°), radial deviation 5.1° (2.8°) from index to the little fingers. Thumbs were typically straight, whereas the index and middle fingers deviated ulnarly, and ring and little fingers radially. There were no relevant differences in sex or laterality.

Abstract Lameness is a serious health concern for livestock species. Understanding individual animal response to pain and characterization of lameness are critical when developing appropriate treatments. The objectives of this pilot study was to evaluate two different lameness models and measures for determining response to induced lameness in meat goats. Lameness was induced by intraarticular injection into the left hind lateral claw distal interphalangeal joint with either amphotericin B (Amp-B) or kaolin-carrageenan (K-C). Response to lameness was characterized by behavior scoring, visual lameness scoring (VLS), infrared thermography (IRT) of the affected digit, pressure mat gait analysis (PMT), and plasma cortisol (CORT) analysis. Lame goats had higher VLS compared to controls (P = 0.003). Maximum temperatures measured in hooves from lame vs control goats were significantly higher (P = 0.003). Pressure mat analysis demonstrated, when compared to controls, lame goats had decreased force (P = 0.013), impulse (P = 0.007), contact pressure (P = 0.007), and contact area of the left hind limb (P = 0.009). Mean CORT levels 4 and 6 h after lameness induction were higher in lame goats (P = 0.005, P = 0.01). The two lameness methods reliably induced lameness of varying severity in healthy meat goats.
