Acute Hand and Wrist Injuries

Introduction

Acute hand and wrist injuries account for a substantial share of emergency department and urgent care visits, and the consequences of undertreating them are not subtle. A finger fracture that is splinted in the wrong position can heal stiff. A tendon laceration that goes unrecognized for weeks may not be repairable. A dislocation reduced without imaging can mask an associated fracture or ligament tear. The hand is unforgiving of delay and unforgiving of imprecise care.

I practice as a dual board-certified plastic and hand surgeon in Austin, Texas, with academic Affiliate Faculty appointments at Dell Medical School at The University of Texas at Austin and a partner in the Seton Institute for Reconstructive Plastic and Hand Surgery. Trauma — fractures, replantation, microsurgery, and soft-tissue reconstruction — is an explicit part of my clinical practice and the area in which my published work is densest. This page is an orientation to the major categories of acute hand and wrist injury, the principles that guide their treatment, and the timing windows that matter.

When Acute Hand or Wrist Injuries Need a Hand Surgeon

Most acute hand injuries are first evaluated by emergency or urgent-care clinicians, and many can be managed there. Hand surgery referral is appropriate when:

• The injury involves the joint surface, displaces a bone fragment, or rotates a digit. These features change non-operative management into operative management. A spiral phalanx fracture that looks innocuous on an AP film may rotate the finger across its neighbor when the patient makes a fist — a clinical exam finding that a hand surgeon recognizes and an x-ray does not show.
• There is concern for a tendon, nerve, or vessel injury. Lacerations on the volar (palm) surface of the hand and wrist sit close to multiple critical structures, and the threshold for surgical exploration is low. Inability to flex or extend a digit at a specific joint, sensory loss in a specific nerve distribution, or a pulseless digit all warrant emergency evaluation - seek care or call 911.
• The injury involves an open fracture, an amputation, or significant soft-tissue loss. These are time-sensitive - seek care or call 911.
• A previous fracture, dislocation, or laceration is not healing as expected. Persistent pain, deformity, or stiffness weeks after an injury that "looked okay" often indicates a missed component.

Hand and Wrist Fractures

Fractures of the hand and wrist range from straightforward injuries that heal predictably with splinting to complex multi-fragment patterns that require precise surgical fixation. The categories below cover the most common presentations.

Distal Radius Fractures

The distal radius — the wrist end of the larger forearm bone — is the single most commonly fractured bone in adults. These injuries typically occur after a fall onto an outstretched hand. Treatment depends on fracture pattern, displacement, joint surface involvement, fracture stability, and the patient's functional demands.

Stable, well-aligned distal radius fractures often heal well with closed reduction and casting. Displaced or unstable patterns, intra-articular fractures, and fractures in patients with high functional demands more often warrant surgical fixation. Surgical options include volar plate fixation, fragment-specific fixation, dorsal plating, and external fixation. The choice depends on the fracture geometry and the soft-tissue envelope.

I authored a chapter on distal radius fractures in the University of Michigan Comprehensive Guide to Upper Extremity Fracture Surgery, which addresses the evaluation, classification, and operative decision-making for these injuries in detail.

Scaphoid Fractures

The scaphoid is the most commonly fractured carpal bone. The injury typically presents as wrist pain after a fall onto an outstretched hand, often with point tenderness in the anatomic snuffbox. Initial radiographs may not show the fracture, which is one of the reasons clinical examination matters — patients with the right mechanism and the right tenderness deserve immobilization and re-evaluation even if x-rays are negative.

Scaphoid fractures matter because the bone has a tenuous blood supply. Untreated or undertreated scaphoid fractures can progress to nonunion or avascular necrosis, which over years produces a specific pattern of wrist arthritis (scaphoid nonunion advanced collapse, or SNAC). Stable nondisplaced fractures may heal with appropriate immobilization. Displaced fractures, proximal pole fractures, and patients with high functional demands often benefit from percutaneous or open screw fixation.

Non-unions (failure to heal) of scaphoid fractures may require bone grafting, often with vascularized bone. Sometimes this vascularized bone with a blood supply can come from the same hand and sometimes bone with more structure or joint surface is required. In some cases, we may even perform microsurgery to transfer knee or femur bone to the wrist to restore the surface to these bones - such as in medial fermoral condyle or medial femoral trochlear flaps.

Metacarpal and Phalangeal Fractures

The hand bones — metacarpals in the palm, phalanges in the fingers — fracture in patterns that depend on mechanism. A "boxer's fracture" of the small finger metacarpal neck is a common closed-fist injury. Spiral phalangeal fractures from twisting injuries can produce malrotation that becomes obvious only when the patient flexes the fingers. Intra-articular fractures involving the proximal interphalangeal joint are technically demanding and have a low margin for error.

Surgical fixation of hand fractures uses a range of techniques: percutaneous pinning with wires, intramedullary screws, plate-and-screw constructs, and external fixation in select cases. The right operation depends on the fracture pattern, displacement, joint involvement, and the patient's hand demands.

I have also written for the American Society for Surgery of the Hand's patient education platform on hand fractures, contributing to the broader effort to make accurate hand-injury information available to patients online.

Tendon Injuries

Tendon lacerations are surgical emergencies in the relative sense — outcomes degrade meaningfully with delay, and proper repair within days produces better results than delayed repair weeks later.

Flexor Tendon Injuries

The flexor tendons run on the palm side of the fingers and wrist and bend the fingers when they contract. Lacerations of the flexor tendons are classified by zone, and Zone II — the segment of the tendon that runs through the digital sheath and pulley system between the proximal end of the A1 pulley and the insertion of the flexor digitorum superficialis — is the most technically demanding to repair. The space inside the digital sheath is constrained, the two flexor tendons (superficialis and profundus) move past each other, and post-operative scarring can defeat an otherwise excellent repair.

Modern flexor tendon repair uses multistrand core sutures with epitendinous reinforcement and is followed by a structured rehabilitation protocol that begins early — sometimes within days of surgery. The rehabilitation determines the outcome as much as the surgery does. My published research with the University of Michigan group, in Plastic and Reconstructive Surgery — Global Open, examined the effect of time to hand therapy following Zone II flexor tendon repair and found that earlier initiation of structured therapy was associated with better outcomes. Patients who delay or skip hand therapy after flexor tendon repair generally do not achieve their potential recovery.

Extensor Tendon Injuries

The extensor tendons run on the back of the hand and fingers and straighten the digits. Extensor injuries are also zone-classified, with treatment depending on zone, mechanism, and whether the injury is open or closed. Some extensor injuries — particularly mallet finger (a closed avulsion of the terminal extensor tendon at the distal phalanx - the last joint on a finger) — can be treated with prolonged splinting alone if the avulsion is small and the joint is congruent. Larger fragments, displaced fractures, and open lacerations more often require surgical repair or fixation.

FDP Avulsion (Jersey Finger)

A specific high-stakes tendon injury worth naming individually: avulsion of the flexor digitorum profundus from the distal phalanx, classically when a finger catches in another player's jersey during a tackle. Prompt recognition and referral are essential.

‍

Dislocations and Ligament Injuries

Dislocations of hand and wrist joints range from finger PIP joint dislocations — common in athletes and often reducible at the bedside — to major perilunate dislocations of the wrist that represent severe ligament disruption.

Finger Dislocations

Most simple PIP joint dislocations can be reduced under digital block, splinted briefly, and started on early protected motion. The clinical workup matters, however: post-reduction radiographs confirm a concentric reduction, and a careful examination assesses for collateral ligament integrity and any associated fracture. A "simple dislocation" that re-dislocates on early motion suggests an unstable injury that needs further treatment.

Wrist Ligament Injuries

The wrist contains an intricate set of ligaments that maintain carpal bone alignment. Acute injury — most commonly a fall onto an outstretched hand — can disrupt the scapholunate ligament, the lunotriquetral ligament, or, in higher-energy injuries, produce a perilunate dislocation. These injuries are easy to miss on initial radiographs and produce long-term arthritis if undiagnosed and untreated.

Patients with persistent wrist pain after an apparent "sprain" deserve dedicated evaluation. Specific radiographic views, MRI, and sometimes wrist arthroscopy are used to clarify the diagnosis. Treatment ranges from immobilization for partial ligament tears to acute repair, ligament reconstruction, or limited carpal fusion for complete tears.

Thumb Ligament Injuries

The most clinically important thumb ligament injury is rupture of the ulnar collateral ligament of the thumb metacarpophalangeal joint — sometimes called "skier's thumb" for its acute presentation or "gamekeeper's thumb" for the chronic version. This ligament stabilizes the thumb during pinch and grip. Complete tears do not heal reliably with splinting, particularly when the torn ligament displaces above the adductor aponeurosis (a Stener lesion), and surgical repair is the standard treatment.

‍

Replantation and Revascularization

Amputations of digits, hands, or arms are time-sensitive surgical emergencies. The viability of the amputated part depends on warm ischemia time — how long the tissue has been without circulation — and on cold ischemia time once the part is properly preserved.

The amputated part should be wrapped in saline-moistened gauze, placed in a sealed plastic bag, and the bag placed on ice. The tissue should not be placed directly on ice or in water. The patient and the part should be transported together to a center capable of replantation.

Whether replantation is offered depends on multiple factors: the level of amputation, the mechanism (clean cut versus crush versus avulsion), the number of digits involved, the patient's age and medical status, and the patient's hand demands. Not every amputation should be replanted — a single distal fingertip amputation in an adult often heals better with revision amputation than with replantation, and a severely crushed or avulsed part may not be salvageable. Multi-digit amputations, thumb amputations, and amputations in children carry stronger replantation indications because the functional cost of revision amputation is higher.

Replantation involves bone fixation, tendon repair, microvascular anastomosis of arteries and veins under the operating microscope, and nerve coaptation. Post-operative monitoring is intensive. The work falls within the dual training of plastic and hand surgery — a combined orthopedic and microsurgical skill set is essential.

Nerve Injuries (Brief Overview)

Acute peripheral nerve injuries — most commonly from sharp lacerations on the palm or wrist — can present subtly. A laceration that heals at the skin level may have transected an underlying digital nerve, producing numbness in a specific distribution that is not always obvious to the patient until weeks later. The threshold for exploration is low when the injury location and mechanism are consistent with possible nerve involvement.

When primary repair is feasible, it is performed under microscopic magnification with meticulous tension-free coaptation. When a gap exists or primary repair is not possible, options include nerve grafts, processed nerve allografts, conduits, and nerve transfers. For a detailed discussion of nerve repair, nerve transfer, and Regenerative Peripheral Nerve Interfaces (RPNI) for amputation neuromas, see the [peripheral nerve surgery page].

Soft Tissue Injuries Requiring Reconstruction

Open wounds with skin, muscle, tendon, or bone exposed cannot heal by simple wound care. Reconstructive coverage matched to the defect — skin grafts for shallow wounds with vascularized beds, local flaps for moderate defects, regional flaps for larger defects, or free tissue transfer for the largest or most contaminated defects — is part of the treatment plan from the outset.

Soft-tissue reconstruction in upper extremity trauma is one of the published interests in my practice. My Hand Clinics review on soft-tissue coverage for elbow trauma addresses the reconstructive options when bone, tendon, or hardware is exposed in the elbow region — the same principles inform reconstruction of more distal injuries. The combined plastic surgery and hand surgery training that I bring to these cases is the framework that supports treating an injured hand as a complete biological system rather than as separate components.

Pain Management After Acute Hand Injury

Acute hand injury and the operations that treat it can be painful. Modern pain management uses multimodal approaches that minimize opioid exposure: regional anesthesia (digital blocks, wrist blocks, brachial plexus blocks), scheduled non-opioid analgesics, ice, elevation, and immobilization.

My systematic review of acute postoperative pain management in hand surgery, published in the Journal of Hand Surgery — American, reviewed the evidence base for these approaches and supports a stepped, evidence-based protocol that limits opioid use to where it adds genuine value. The findings inform how I manage post-operative pain in my own practice.

Frequently Asked Questions

Should I go to the emergency room or urgent care for a hand injury?

For deep lacerations, amputations, open fractures, suspected vascular injury (a cold or pulseless digit), high-energy injuries, or injuries with exposed bone or tendon, go to an emergency department. For closed injuries, sprains, and small lacerations, urgent care is reasonable although you may be transferred to a formal ED if they find further evidence of deep injury. Either pathway can refer to a hand surgeon if needed. When in doubt, the higher-acuity setting is the safer choice. In Austin, my partners and I cover hand call 24 hrs per day at the Dell Seton Medical Center at the University of Texas where hand surgeon consultation is available as part of comprehensive trauma care.

How quickly do tendon lacerations need to be repaired?

Most tendon lacerations should be repaired within one to two weeks of injury. Earlier is generally better, but the operation does not need to happen on the same day in all cases. Delay beyond a couple of weeks risks tendon retraction, muscle shortening, and loss of repair quality. Specific timing depends on which tendon is injured.

What should I do if I cut off my finger?

Apply pressure to control bleeding. Wrap the amputated part in saline-moistened gauze, place it in a sealed plastic bag, and put the bag on ice — do not place the part directly on ice or in water. Bring the patient and the part together to an emergency department capable of replantation - a LEVEL 1 trauma Center. In Austin, the only level 1 trauma center is Dell Seton Medical Center at the University of Texas. Time matters; do not delay transport to find a perfect container.

How long does a hand fracture take to heal?

Most hand fractures heal in six to eight weeks, though radiographic healing and clinical healing are not identical. Functional recovery — full range of motion, grip strength, and return to work — typically takes longer and depends on the location, the treatment, and adherence to hand therapy. Some fractures, particularly intra-articular fractures, may have permanent residual stiffness or arthritis even with optimal treatment. In children, this may occur more quickly depending on many factors.

Can I just wait and see if my finger heals on its own?

Some hand injuries do heal on their own. Many do not. Closed fractures that are non-displaced and not rotated, mild sprains, and small lacerations of skin alone often resolve with appropriate splinting and time. Displaced fractures, rotated digits, tendon injuries, nerve injuries, joint instability, and significant lacerations generally do not improve with watchful waiting. The challenge is that telling these apart requires examination and imaging, not self-assessment.

Will I be able to use my hand normally after a serious injury?

Functional recovery after acute hand injury depends on the injury, the treatment, the timing of the treatment, and the rehabilitation. Many injuries recover essentially full function. Some — particularly intra-articular fractures, complex tendon injuries, and nerve injuries — most often leave residual deficits. The most reliable predictor of outcome is the combination of accurate diagnosis, appropriate treatment, and committed hand therapy. Patients who engage seriously with rehabilitation generally do better than those who do not.

Do I need surgery for a finger dislocation?

Most simple finger dislocations can be reduced and treated non-operatively with brief splinting and early protected motion. Surgery is considered when the dislocation cannot be reduced, when it re-dislocates, when there is an associated fracture, or when ligament damage produces ongoing instability. Imaging after reduction is important to confirm a concentric joint and look for associated injuries.

Why would an amputation not be replanted?

Replantation is offered when the amputated part is clean enough, the patient healthy enough, and the expected functional result better than revision amputation. Severely crushed or avulsed parts, single digit injuries, distal fingertip amputations in adults, and certain medical contraindications may make revision amputation the better choice. The decision is individualized and made jointly with the patient.
