The use of ultrasound to predict flexor tendinopathy after anterior locking plating of the distal radius.

This study compares ultrasound to clinical and radiographic measurements for assessing tendon pathology associated with distal radial anterior locking plates. A total of 46 patients undergoing removal of a distal radial plate had a preoperative clinical examination, radiographs and ultrasound evaluation to detect evidence of tendon irritation. Gross changes to the tendon were assessed during plate removal.

Necrotizing Soft Tissue Infection Following a Closed Distal Radius Fracture: A Case Report and Literature Review.

Necrotizing soft tissue infections (NSTIs), characterized by extensive soft tissue destruction, are rare but life-threatening. We present a case of a NSTI in a healthy 65-year-old woman following a closed distal radius fracture. The patient presented with severe pain, fever, and lethargy 4 days after her index injury, with physical examination of the right upper limb revealing erythema and swelling to the mid-humeral level and blisters of the fingers and hand.

Sagittal Band Injuries: A Review and Modification of the Classification System.

Sagittal band injuries, although relatively uncommon, can be difficult to treat. This review provides a contemporary perspective on this pathology, as well as a modification to the classification system. This modification aims to incorporate the spectrum of disease seen, guide treatment, and allow standardization when documenting and describing injuries.

Hemi-hamate Arthroplasty for Base of Middle Phalanx Fracture: A Systematic Review.

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.

Mechanics of Metacarpophalangeal Joint Extension.

Purpose: It is a common belief that extension of the metacarpophalangeal (MCP) joint of the finger is achieved via the sagittal bands acting as a sling or lasso to attach the extensor tendon to the base of the proximal phalanx. The aim of this study was to test the hypotheses that (1) division of the sagittal bands reduces extension force or torque of the MCP joint, and (2) division of the extensor tendon distal to the sagittal band will not affect the extension force or torque of the MCP joint.

Methods: Ten cadaver limbs were secured to a jig to allow for testing of the extension force of the MCP joints of the index, middle, and ring fingers.

Adhesion formation after flexor tendon repair: comparison of two- and four-strand repair without epitendinous suture.

Increased handling, increased bulk at the repair site and an increase in external suture material may affect adhesion formation and gliding after tendon repair. A previous study(1) showed no significant difference in biomechanical or histopathological measurement of adhesion formation in two- and four-strand repairs combined with an epitendinous suture in the chicken model. In the present study, the flexor digitorum profundus tendon of the middle toe of 47 broiler chickens was cut and repaired with either a single (two-strand) or double (four-strand) modified Kessler core suture without epitendinous suture and immobilised for four weeks.

Adhesion formation after flexor tendon repair: a histologic and biomechanical comparison of 2- and 4-strand repairs in a chicken model.

Purpose: Both increased handling and increased bulk at the repair site have been hypothesized as affecting adhesion formation and gliding after tendon repair. Tendons repaired with 2- and 4-strand techniques were compared using both biomechanical and histopathologic measurements to determine the influence of increasing strand number on adhesion formation and gliding.

Methods: The flexor digitorum profundus tendon of the right middle toe of 80 broiler chickens was cut and then repaired with either a single (2-strand) or double (4-strand) modified Kessler core suture, followed by a running epitendinous suture.

Low-intensity ultrasound stimulation in distraction osteogenesis in rabbits.

Low-intensity pulsed ultrasound has been shown to accelerate fracture healing. This experiment investigated its possible role in distraction. Thirty-four New Zealand White rabbits had distraction osteogenesis, followed by low-intensity pulsed ultrasound therapy.
