Assessment of Complications of Distal Radius FracturesMcKay, MacDermid, Roth et al J Hand Surg 2001
• Evaluated incidence and types of complications in consecutive cohort
• Developed “check list” with classification and severity
• Evaluated difference in physician-reported vs patient reported

McKay et al J Hand Surg 2001
• Physician-reported in 235 pts -27%
• Patient-reported in 207 pts-- 21%
• Suggested patients more focused on symptoms rather than diagnoses
McKay et al J Hand Surg 2001Classification and rating of complication
• Mild—symptoms caused by the fx (or rx) but resolved with no treatment (1pt)
• Moderate-- required specific treatment such as therapy or splint (2 pts)
• Severe– required surgical treatment (3 pts)
McKay et al J Hand Surg 2001complexity of evaluation-ex median nerve
• Can be preexisting condition
• Can occur acutely with fracture
• Can be the result of intraoperative rx
• Can occur with increased postop swelling
• Can be later due to malunion

LOSS OF FIXATION OF THE VOLAR LUNATE FACET FRAGMENT IN
FRACTURES OF THE DISTAL PART OF THE RADIUS
Harness NG, Jupiter JB, Orbay JL, Raskin KB, Fernandez DLJBJS 86 A: 1900-1908, 2004
7 patients, average follow up 24 months after surgery
AO classification: 1 B3.2, 6 B3.3
4 had repeat ORIF
1 had a radiocarpal arthrodesis
2 had no further treatment
RESULTS (average 2 years after surgery)
6 patients returned to previous level of function
Average wrist extension 48° (75% of uninjured side)
Average wrist flexion 37° (64% of uninjured side)
4 patients had repeat ORIF with good maintenanceof reduction and carpal alignment
2 patients declined further treatment had tolerablesymptoms despite carpal subluxation
1 patient had a successful RSL arthrodesis
Loss of Reduction-strategies

COMPLICATIONS(osteoarticular)
POSSIBLE CAUSES
-over-distraction of fracture line with external fixation
-failure to graft large defects in comminuted fractures
-extensive devascularisation during initial ORIF
-unstable construct and cast-free aftertreament
-inadequate period of immobilisation

NONUNION OF THE DISTAL RADIUS
TYPES: -fibrous „stable“ nonunion-synovial „mobile“ non-union
delayed union: lack of radiographic signs of healing after 4 monthsNon-union: fractures failed to heal 6 months after injury
PROBLEMS: -small osteopenic distal fragment
-wrist and distal radioulnar jointcapsular contracture
-soft tissue contracture (brachioradialis)
-significant shortening (DRUJ disruption)
Strategies(1)Wrist arthrodesis
• 12 ununited fractures of the distal radius• ORIF not feasible• Distal fragment too small and osteopenic• Poor results commonplace• Multiple surgeries to achieve fusion• Wrist and digit stiffness• Sensory abnormalities
Segalman & Clark, ASSH 1994
-correction of deformity : -axial realigment-restoration of radial length
-soft tissue release : -dorsal wrist capsulotomy(if necessary) -DRUJ capsulotomy
-tenotomy brachioradialis
-internal fixation and and autologous bone grafting (iliac crest)
-additional DRUJ procedure if realignment not possible:-ulnar shortening-ulnar head prosthesis-ulnar head resection (older age group)

ORIF of Un-united Fractures of the Distal Radius:Does the Size of the Distal Fragment Affect the Result?
Prommersberger KJ, Fernandez DL, Ring D, Jupiter JB2000
-13 patients with a distal fragment with more than 5mm ofsubchondral bone supporting the articular surface
-10 patients with an un-united fracture with a distal fragmentsmaller than 5mm

1. LOSS OF REDUCTION
2. DELAYED UNION AND NONUNION
3. MALUNION
4. DISTAL RADIOULNAR JOINT
COMPLICATIONS(osteoarticular)
Three basic conditions:
1) Painful non-union of the ulnar styloid (no instability)
2) Capsular retraction (pronatory contracture)
3) Radio-ulnar impingement (following resection of the
ulnar head or unstable Sauve-Kapandji stumps)
Less frequent problems:
(these findings may present isolated or combined!!)
Incongruency, impaction and instability.
INCONGRUITYExtra-articular: abnormal orien-
tation of the joint surfaces due
to metaphyseal deformity of the
radius, ulna or both.
79
80
81
7/13/2021
28
INCONGRUITYIntra-articular: following fractures
entering the sigmoid notch, ulnar
head or both.
Ulnocarpal arthritis secondary
to chronic ulnar impaction.
(post-traumatic radial shortening)
INCONGRUITY--Strategies
A) Extra-articular: reorient sigmoid notch withRADIAL OSTEOTOMY
B)Intra-articular (Post-traumatic arthrosis): depending on the severity ofdegenerative changes, age, hand dominance, occupation
- RESECTION ARTHROPLASTY
- SAUVE-KAPANDJI PROCEDURE
- PROSTHETIC REPLACEMENT
C) Combined (Extra- and intra-articular):
RADIAL OSTETOMY and DRUJ PROCEDURE as in B)
EXTRA-ARTICULARINCONGRUITY OF THE DRUJ:
Reorient sigmoid notch to ulnarhead with radial ostetotomy

RESECTION ARTHROPLASTY-StrategiesPartial ulnar head resection (Bowers, Watson)
INDICATIONS:
LOW FUNCTIONAL WRIST DEMAND
Elderly patients, non-dominant hand, light manual activities
PRE-REQUISITES: neutral ulnar variance,otherwise ulnar shortening necessary to preventstylo-carpal impingement
To avoid late radio-ulnar impingement a voluminoussoft tissue interposition is mandatory: ECU anchovyand pronator quadratus!!
modified Bowers procedure with ECU “anchovy“ and pronator quadratus interposition

ULNO-CARPAL ABUTMENT
IMPACTIONAbnormal contact of two bony surfaces
due to radial shortening (synonyms: ulno-carpal abutment or impingement syndrome
IMPACTION or ULNAR ABUTMENT: Strategiesulnar shortening OT
-decompresses ulnar compartment-tightens ulno-carpal ligaments-controls instability
Pre-requisites: well oriented sigmoidnotch, no step-offs, no degenerativechanges
Tolat and Stanley classification

After 20 weeks, a distal radius fracture is probably
healed,
in order to minimize the flexor tendons rupture risk:
•Should protruding plates be removed, even if non-
symptomatic?
•Should even slightly or not protruding plates be
removed, if symptomatic?
•Should every plate be removed in younger patients?

Complications of Volar Plate Fixation for Managing Distal RadiusFractures
Lisa M. Berglund, MD and Terry M. Messer, MD
Benson et al evaluated the third extensor compartment through a limited dorsal incision in a clinical study of 10 patients. The authors identified postreduction bone spurs, dorsal gapping at the fracture site, and prominent screw tips as potential causes of EPL rupture.

REMEMBER“ Hand fractures can be complicated by
deformity from no treatment, stiffness from over treatment, and both deformity and stiffness from poor treatment….”
Swanson,A. Ortho Clin N.A, 1970
2
Spiral & oblique phalangeal fractures must be checked for malrotation
Assess active synchronous composite digital flexion w/ or w/o a metacarpal block
3
Fractures of the base of the proximal phalanx (meta-diaphyseal junction)…..
….. difficult to assess sagittal plane angulation on AP & lat.views. Oblique views + clinical assessment (for pseudo-clawing) are important in determining treatment
Faruqui, Stern, Kiefhaber. JHS, 2012
4
Condylar fractures of the head of P1 or P2 are usually unstable…..
……..If managed non-operatively, close follow-up with serial radiographs are mandatory.

Corollary: Condylar fractures
Single pin or screw fixation of condylar fractures is inadequate.

Plate fixation of phalangeal shaft fractures (flexor tendon zone II)……
…….is sexy but may not be all its cracked up to be.
After tenolysis

Corollary: Percutaneous fixation of unstable phalangeal shaft fractures…..
…….is not sexy but often does the trick.
8
Direct dorsal plating of phalangeal fractures can be risky………..
….....Screws that inadvertently penetrate the volar cortex can impair flexor tendon excursion or cause flexor tendon rupture

No Heroics: Gun shot injuries that ‘take out’ the metacarpal head and base of proximal phalanx of the border digits should strongly be considered for amputation. Salvage is a multi-step process that often results in short, stiff, and painful finger.

EXTERNAL FIXATION of comminuted open fractures of the phalanges (and metacarpals) is frequently the
better part of valor.
Ashmead D IV et al. JHS, 1992
13
Phalangeal shortening is poorly tolerated and is under-rated. Metacarpal shortening (up to 5 mm) is
over-rated and generally well tolerated
• There is a linear relationship b/t P-1 shortening and PIPJ extensor lag.
• For each mm of shortening 10° PIPJextensor lag
Vahey, Hastings, Wegner: J Hand Surg, 1998
14
………. Allows for intraoperative assessment of rotationby having the patient actively make a fist.
Consider WALANT (w/ or w/o sedation) for fixation of phalangeal fractures…………………
15
Quote from a highly respected A.O. surgeon and friend: regarding K-pins: “Pins penetrate, incinerate, irritate and
incarcerate” BUT in my opinion pin fixation is not a sign of weakness; they are forgiving, versatile, and minimize soft
tissue damage.
16
Interfragmentary fixation of spiral phalangeal & metacarpal fractures:
• Don’t forget to countersink• Lagging can be dangerous• Upon insertion: if there is resistance on the
far cortex: STOP• Close the periosteum when
possible
17
MANAGEMENT OF INFECTED FRACTURES
• Eliminate sepsis– Debride, cultures, antibiotics– Remove implants (especially if loose)
• Secure union ( staged procedure)– Ex. Fix. + PMM spacer– bone graft + stabilization (Masquelet)
• Regain function
