We present a case of a young man with heavily injured proximal interphalangeal joints and deficits of the extensor mechanism in 2 fingers treated by silicone proximal interphalangeal joint arthroplasty and 2-stage reconstruction of the extensor mechanism. The postoperative result was satisfactory with a painless, if limited, active arc of motion of the proximal interphalangeal joints of 50° in the middle finger and 35° in the ring finger.

Background: Arm-lifting movements (shoulder flexion) are essential for upper extremity rehabilitation after a stroke. Abnormal flexor synergy (elbow flexion) is frequently observed during shoulder flexion, impeding functional improvement. However, no quantitative method exists for assessing abnormal flexor synergy.

A 27-year-old man sustained right ring and little finger proximal interphalangeal joint fracture dislocations. He subsequently underwent bilateral hemi-hamate autograft to treat these intra-articular injuries. The patient was followed periodically and demonstrated return of normal grip strength and radiographic union of the hemi-hamate reconstruction arthroplasties.

Purpose: Terminal extensor tenotomy or Dolphin tenotomy, is a described treatment for the management of distal interphalangeal (DIP) joint hyperextension in chronic boutonniere deformity. The purpose of this study was to investigate the effects of incremental partial Dolphin tenotomy in correcting boutonniere deformity, with a focus on evaluating the improvement in DIP joint hyperextension deformity and documenting the development of iatrogenic mallet finger.
Methods: Thirty-eight fingers from 10 cadaveric hands were used.
Biomechanical Comparison of Surgical Steel Wiring and Suture Tape Tension Band Techniques for Arthrodesis of the Metacarpophalangeal and Proximal Interphalangeal Joint.

Purpose: The purpose of this study was to evaluate the biomechanical properties of SutureTape as an alternative technique for arthrodesis of the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joint arthrodesis when compared with surgical steel wire.
Methods: A total of 32 fingers (index, long, ring, and small) from two matched pair cadaveric hands were used. K-wire and surgical steel wire were used for MCP and PIP joint arthrodesis of the control group (group I), whereas K-wire and SutureTape were used for the experimental group (group II).
[CAN NATURAL SKIN CREASE PREDICT OUR PHALANX JOINT ALIGNMENT?].

Orthopedic Department, Mount Sinai Hospital, Canada.
Background: Proximal interphalangeal injury may result in malalignment of the phalanx axis of motion. In some instances, these fractures are treated with an external fixation method such as Suzuki-type fixation, during which the surgeon must perform X-rays to preserve the phalanx anatomical axis of motion.
Objectives: To assess the correlation between the palmar skin crease and the joint axis of the proximal interphalangeal joint (PIPJ) of the fingers opposing the thumb to improve the surgeons' perioperative planning procedure.
