Postoperative treatment of distal phalangeal injuries

The aftercare can be divided into four phases of healing:

• Inflammatory phase (week 1–3)
• Early repair phase (week 4–6)
• Late repair and early tissue remodeling phase (week 7–12)
• Remodeling and reintegration phase (week 13 onwards)

• Principle: protection of the injured (operated) hand to facilitate uneventful healing
• Aim: healing without complications while facilitating early movement

The patient is encouraged to position the arm to facilitate lymphatic and venous drainage to avoid swelling.

A sling should be used to support the hand and forearm when the patient is mobile. Ideally, the hand should be held higher than the elbow to avoid edema caused by dependency.

These are intended to avoid edema in inactive soft tissues leading to interstitial fibrosis, adhesions, and contractures.

The patient should be encouraged to touch the skin of the affected hand (and fingers) and to use the hand (and fingers) to touch surfaces and objects as comfort permits. This encourages the restoration, retention, and maintenance of cutaneous and articular sensibility and may contribute to avoiding adverse events such as complex regional pain syndrome.

Specific exercises are determined by the injury pattern and treatment undertaken. Patient education and monitoring are ideally undertaken by a hand therapist.

Exercises should not provoke pain. Self-directed exercises are encouraged: frequent sets of low-amplitude, high-repetition movements are safer and more easily performed than infrequent sets of high-amplitude movements.

Resting between sets of exercises must be in a posture which avoids dependent swelling.

• Principle: continued protection of the injured (operated) hand with the promotion of directed tissue repair
• Aim: established healing of injured tissues with isometric strength

The same principles apply as in the first phase.

As soft-tissue healing progresses and swelling subsides, splintage can be removed for greater periods of time during which functional activities can be performed.

Resistance exercises can be introduced in addition to the exercises of the first phase.

• Principle: reestablishment of proprioception in the hand
• Aim: encourage normal tissue structure and reinnervation through daily activities without secondary injury

The limb can be rested without elevation. But long periods of dependent positioning should be avoided as swelling can still occur.

The need for external splintage is dictated by functional demands. Temporary or removable splintage may be used to protect the healing limb or joint.

Functional exercises are dictated by the specific injury or operation. The aim is to introduce activities relevant to the patient’s occupation or functional needs.

• Principle: normalization of the proprioceptive function with optimal biomechanics
• Aim: to establish normal tissue structure and reinnervation through training and practice for optimal endurance

Recurring swelling should not occur in this stage and the need to rest or position the limb is no longer required.

Normal occupational and personal activities should be resumed.
