This article describes an immediate active motion protocol for primary repair of zone I flexor tendons treated with tendon to tendon, or tendon to bone repair, and reviews clinical results. A rehabilitation protocol is proposed that will limit excursion of the zone I repair by blocking full distal interphalangeal (DIP) extension and by applying controlled active tension to both the unrepaired flexor digitorum superficialis (FDS) and the repaired flexor digitorum profundus (FDP). The rehabilitation technique utilized a dorsal protective splint with a relaxed position of immobilization with 30 degrees of wrist flexion, 40 degrees of metacarpophalangeal (MP) joint flexion, and a neutral position for the proximal interphalangeal (PIP) joints without dynamic traction. ⋯ Mean total active range of motion was 142 degrees (PIP 95 degrees plus DIP 47 degrees), or 81% of normal. Three tendons ruptured in non-protocol-related incidents and were excluded from the study. Results from this clinical study support the use of limited DIP extension combined with active tension with conventional repair in zone I.

The authors conducted a systematic review to determine if there is scientifically valid (level I or II) evidence for the effect of early motion (<21 days) of joints surrounding an extraarticular hand fracture on fracture healing or functional outcomes. Two reviewers independently evaluated for study inclusion, trial quality and internal validity. Six poor-quality, quasirandomized studies (level III evidence) involving 459 patients were included. ⋯ The scientific validity of EM interventions after an extraarticular hand fracture has not been established in well-conducted, randomized, controlled trials (level I or II evidence). Current evidence does not support or refute the use of EM after an extraarticular hand fracture. However, further investigations are warranted, as findings to date show a consistent potential for benefit with no significant risk of harm when early regional joint motions are incorporated into the management of closed, extraarticular, finger metacarpal fractures.

This article presents early controlled mobilization options for potentially unstable, nondisplaced, nonarticular hand fractures. Early controlled mobilization of tissues surrounding a healing fracture has the potential to enhance the quality and rate of fracture healing and a person's functional recovery. The options discussed protect the integrity of the fracture alignment, while permitting safe, pain-free protected motion of joints adjacent to the fracture. ⋯ If clinically unstable, the fracture often is considered unable to tolerate unrestricted active motion during the initial stages of healing. This article offers an alternative perspective, in which clinicians can consider the clinical factors that can be controlled to allow for early protected motion of the regional tissues surrounding a potentially unstable hand fracture. These additional clinical options offer an alternative to acute fracture immobilization and help progress the rehabilitation of hand fracture patients.

This article addresses current approaches for the rehabilitation of distal phalanx and middle phalanx fractures, excluding proximal interphalangeal joint avulsion fractures. Emphasis is placed on establishing the optimal rehabilitation program based on an understanding of the type and location of the fracture, method of fracture management, fracture stability, fracture healing, complications from soft tissue injuries, and recognizing and preventing common problems associated with fractures. Patient case examples and results reported in the literature are included.

Review
Fracture healing: bone healing, fracture management, and current concepts related to the hand.
Bones fracture frequently and often result in significant impairments, functional limitations, and disabilities, especially when the hand is involved. When fractures occur, there is a disruption of the skeletal tissue organization and a loss of mechanical integrity. ⋯ This article briefly reviews the history of fracture healing and the advances in mechanics and cellular and molecular biology, which should help the reader better understand the current mechanisms related to bone healing (primarily and secondarily). Fracture fixation modes also are described along with the temporal sequencing as to when to protect or move the fractured region.
