Insights
Paediatric fifth metacarpal neck fractures (FMCNFs) with less than 30° angulation and no rotation can be treated with immobilisation alone. Higher angulation or rotational deformities require fracture reduction and surgical fixation for optimal outcomes.
Area of Science:
- Orthopaedic Surgery
- Paediatric Hand Fractures
- Traumatology
Background:
- Fifth metacarpal neck fractures (FMCNFs) are common in children.
- These fractures can lead to reduced metacarpophalangeal (MCP) range of motion and grip strength.
- Current management indications for paediatric FMCNFs are not standardized.
Purpose of the Study:
- To systematically review evidence on paediatric FMCNF management.
- To determine appropriate treatment pathways for these fractures.
Main Methods:
- Systematic literature search of PubMed, EMBASE, Scopus, and Google Scholar.
- Inclusion of studies on the management of paediatric FMCNFs.
- Analysis of treatment outcomes based on fracture characteristics.
Main Results:
- Ten studies involving 237 paediatric patients were reviewed.
- Immobilisation alone was successful for fractures with <30° angulation and no rotation.
- Fracture reduction and surgical fixation yielded good outcomes for higher angulation or rotational deformities.
Conclusions:
- Paediatric FMCNFs with <30° angulation and no rotational deformity can be managed non-operatively.
- Surgical fixation is indicated for fractures with significant angulation or rotational deformity.
- Standardized treatment pathways for paediatric FMCNFs are proposed.
Background:
Fifth metacarpal neck fractures (FMCNFs) are common among paediatric patients. Complications include reduced metacarpophalangeal (MCP) range of motion and grip strength, which impede the hand's functional abilities. Various management options are available, but indications are not standardised. This systematic review aims to assimilate all available evidence on the management of paediatric FMCNFs to determine appropriate treatment pathways.
Methods:
PubMed (Medline), EMBASE, Scopus and Google Scholar were used to identify evidence pertaining to the management of these fractures.
Results:
Ten studies were identified, involving 237 patients with a mean age of 14.4 years (Range 9-17). Ninety percent of patients were male. Sixty-one (26%) patients, with an average fracture angulation of 27° (Range 16°-33°) and no rotational deformities, were managed with immobilisation alone. These patients returned to normal metacarpophalangeal range of motion and grip strength. Fifty-four (23%) patients, with an average fracture angulation of 42.7° (Range 33°-54°), were managed with fracture reduction and immobilisation. This technique did not yield sustained reduction of fractures with significant angulation or rotation after intervention. One hundred twenty-two (51%) patients, with an average fracture angulation of 48.3° (Range 30°-58°) and including cases of malrotation, were managed with fracture reduction and surgical fixation. These patients experienced good functional outcomes.
Conclusions:
This review suggests paediatric FMCNFs can be safely managed with immobilisation alone when there is an absence of rotational deformity and an angulation of < 30°. In the case of a higher fracture angulation or rotational deformity, fracture reduction and surgical fixation is an appropriate method of management.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
