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.

Fracture Dislocations

Intra-articular fracture dislocations of the base of the middle phalanx are complex and debilitating injuries that present a management conundrum when nonreconstructable. Hemi-hamate arthroplasty (HHA) is a treatment modality of particular use in the setting of highly comminuted fractures. This systematic review aims to summarize the reported outcomes of HHA in this context. A literature search was conducted using MEDLINE, Embase, and PubMed, yielding 22 studies with 235 patients for inclusion. The weighted mean postoperative range of movement at the proximal interphalangeal joint was 74.3° (range, 62.0°-96.0°) and at the distal interphalangeal joint was 57.0° (range, 14.0°-80.4°). The weighted mean postoperative pain Visual Analog Scale was 1.0 (range, 0.0-2.0). The weighted mean postoperative grip strength was 87.1% (range, 74.5%-95.0%) of the strength on the contralateral side. Posttraumatic arthritis was reported in 18% of cases, graft collapse in 4.2%, and donor site morbidity in 3.0%, with a mean follow-up period of 28.4 months (range, 1-87 months). Hemi-hamate arthroplasty is a reliable and effective technique for the reconstruction of intra-articular base of middle phalangeal fracture dislocations, affording symptomatic relief and functional restoration. Further research is required to assess the true incidence of long-term complications.

SummaryShortened fifth middle phalanges, defined as being less than half the length of the fourth middle phalanx, were found in 12 of 96 Philadelphia Chinese and none of 200 Philadelphia Negro children. At least nine of these can be characterized as having stunted cratered diaphyses, with precocious cone epiphyses, which underwent very early epiphyseal union.The possible extension of a current vascular hypothesis for cone epiphyses, to include inherited osseous variation in this region of the little finger, is discussed.A classification of metacarpal brachydactyly is presented, with the intention of investigating the syndrome of pseudopseudohypoparathyroidism. Reports of cases which have been held to negate the theory that Albright's hereditary osteodystrophy is sex linked were found to have the pattern of phalangeal shortening exhibited by one of the forms of metacarpal brachydactyly. This finding lends support to the contention of others that these reported cases are not pseudo-pseudohypoparathyroidism.

An apocrine hidrocystoma occurring on the finger of a 55-year-old man is reported. The lesion presented as a solitary, painless cystic nodule on the dorsal aspect of the middle phalanx of the index finger. Apocrine hidrocystoma is a benign tumour developed from apocrine sweat glands, but the location of the lesion was, however, not consistent with reported locations of apocrine glands in the adult.

Temperature Stimulus

The thermosensory system may misidentify a temperature stimulus with different thermal properties. The mechanism of this hot-cold confusion has not been clarified; hence, it has not yet been applied. In this study, we created a wearable temperature presentation device that is closer to the application and analyzed the tendency and mechanism of temperature confusion by analyzing the hot-cold confusion of temperature sensation in the fingers, which are most frequently in contact with objects. Two experiments were performed. In the first experiment, we presented stimuli on the tips of three fingers (first, second, and third fingers). In the second experiment, we presented stimuli at the center of the distal phalanx, middle phalanx, and proximal phalanx of the first finger. The experimental results indicated the occurrence of hot-cold confusion. Domination, in which the center is dominated by both ends, and a mutual effect, in which the center interacts with both ends, were observed.
